11 Best Penetration Testers For Hire In July 2017 #penetration #testing


Hire the World’s Best Penetration Testers

At a Glance: Penetration Testing

Penetration testing is the practice of performing a software attack on a computer system or network with the goal of discovering weaknesses, exploits, and vulnerabilities. If you’re looking to improve network security or proactively seek to prevent exploits, you’ll need the help of a penetration testing specialist to keep your systems one step ahead of people looking for an easy way into your system.
A penetration testing specialist can design and run tests to assess the ability of your security systems to guard against potential attack vectors. To do this, they may set up either a white box (a target filled with actual system information) or a black box (a dummy file) as a target. The penetration tester then identifies potential exploits and designs attack vectors to potentially breach the system. The penetration tester can also design attacks that can expose other exploits that have yet to be predicted. Penetration testing specialists on Upwork can help you improve your network’s defenses by designing, building, and executing penetration tests that reveal vulnerabilities.

Building an IT Infrastructure: Landing Page as a Service

Landing pages can be very powerful, interactive, data-driven experiences that increase sales and drive traffic. However, they require the expertise of developers, designers, and marketing analysts to bring them to life—something many businesses outsource. Here, we’ll look at how to build a Landing-Page-as-a-Service software business from the ground up.

4 Ways to Optimize your Registration Wall

There’s often a debate that happens at companies – should you force registration or should you allow your site to be open to users and then hope to provide enough value that they register later. While I understand the merits of the second and think that optimizing the experience to reveal some parts of the site is great, giving the entire experience away for free is a waste of an opportunity to capture the email

Colorado Bureau Of Investigation Admits Dozens Of Faulty DUI Blood Tests –


Colorado Bureau Of Investigation Admits Dozens Of Faulty DUI Blood Tests

DENVER (CBS4) Responding to a CBS4 investigation, the Colorado Bureau of Investigation has acknowledged at least 56 of the DUI blood tests it conducted in the last six months were incorrect.

“The initial results in each of those 56 cases showed lower alcohol levels for the drivers than when additional quality assurance retesting occurred, said Susan Medina, a spokesperson for the CBI. “There is no indication that any defendant was inappropriately charged with an offense based on test results showing an erroneously high level of alcohol in a driver’s bloodstream.”

The CBI opened labs in July 2015 in Pueblo and Grand Junction and since then has done about 1,500 DUI blood tests for the Colorado State Patrol and other law enforcement agencies. Medina said the faulty tests amounted to about 4 percent of the DUI testing the labs have conducted since last July.

The CBI said it learned of its erroneous lab results “in recent months“ when an independent lab checked two blood samples that had also been tested by the CBI and the independent lab ChemaTox discovered what the CBI calls “anomalies.

ChemaTox told CBS4 it notified state authorities of the problems in December 2015. The CBI said it then checked some of its other DUI alcohol results and confirmed its lab testing problems.

“While a thorough review remains in progress, said CBI, “it is believed the cause of the anomalies has been identified and corrected.

Medina declined to say if the problem was human error, testing equipment, or some other factor.

Sarah Urfer of ChemaTox labs told CBS4, “I contacted CBI and said, Look, we had an anomaly and it s 24 percent different.’

Urfer said the anomalies are important “because those are people’s lives at stake.

David Miller, a Denver-based defense attorney who defends DUI clients, told CBS4 the CBI needs to come clean.

“It creates a problem with the integrity of the system. They’re not saying what the problem is so we don’t know what the problem is, so we’re going to have to get full disclosure to start with. I think it s up to prosecutors now to look at each case and see if the convictions are proper in the first place and notify the client or lawyer as to what s happening, said Miller.

He said the CBS4 investigation revealing the faulty testing shows a “huge problem. It’s a big deal if you’re the person affected by it. It’s a big deal individually and if you look at the big picture, if you are the person affected by this it’s a very big deal.

Miller said to re-establish credibility, the CBI needs to have all 1,500 blood samples it has examined since last July re-tested.

In many cases, blood drawn from a suspect is a critical piece of evidence establishing either guilt or innocence in DUI cases. There are an estimated 30,000 DUI cases in Colorado each year, according to the CBI.

Dr. Pat Sulik, a chemist with Rocky Mountain Instrumental Laboratories, checked 16 blood samples from the CBI in recent months. She said of those 16 samples, seven were problematic having at least a 5 percent variance from the readings she found. Of those seven, she said five had more than a 10 percent discrepancy.

Dr. Pat Sulik (credit: CBS)

Sulik said she would normally expect to have her results and the CBI results be nearly identical 99 percent of the time.

“To see this many discrepancies when the CBI just started this summer, this is, at a simple overview, way too many discrepancies, said Sulik. “When we saw our first large discrepancy we retested the sample and gave ourselves a heart attack.”

Sulik said the CBI’s erroneous, lower testing numbers mean “they are not being taken off the road, the DUI law is not being enforced if the state lab is coming up with lower numbers.

Sulik said in at least one case she checked, the suspect in a DUI case would have faced a more serious charge had the CBI lab testing been correct the first time around.

Ironically, the CBI only began doing this kind of testing after similar testing by the Colorado Department of Public Health and Environment came under fire in 2013 and CDPHE testing of DUI blood samples was shut down. In that case, defense attorneys maintained that the Department of Health testing was biased in favor of prosecutors and that staff was inadequately trained in handling blood samples.

In 2014 the state Legislature approved a bill providing nearly $2 million in annual funding and the hiring of five new full-time employees for the CBI to take over the DUI blood testing that was previously conducted by the Department of Health. Now the Department of Health is assisting in the investigation of the faulty CBI testing.

According to Medina’s statement to CBS4, ”After the review the CBI will issue amended reports to the law enforcement agencies that submitted the blood samples, and work with stakeholders to ensure accurate scientific results and prosecutions statewide.

Mike Rankin, the CBI Director, said, ”While the CBI works extremely hard to avoid any testing errors in our laboratories, the quality assurance procedures served their designed purpose of safeguarding the integrity of the program.

The CBI declined to answer any other questions from CBS4 citing an ongoing review of what happened. Medina said the agency might be able to provide more information once the review is completed.

Miller told CBS4 he intended to reopen any DUI cases he has handled in the last seven months that involved CBI blood testing. Urfer called the problem “very frustrating. I’ve been through this twice before. It seems like this should be a preventable problem. There are a number of labs that have not had these problems.

LifeBank Placental and Cord Blood Banking – FemmPro OB #femmproobgyn, #femmpro, #professionals


The time of labor and birth of your baby is a wonderful milestone in your family’s life, and a miraculous new beginning. Your baby’s birth is also the perfect time to collect your newborn’s umbilical cord and placenta blood for cryobanking and storage. While many parents are banking their babies’ cord blood, you can actually do more by banking stem cells from two usable sources of stem cell-rich blood: the umbilical cord and the placenta. This service is called placental and cord blood banking, and it is available only from LifebankUSA which is registered with the FDA.

Why is banking stem cells the right thing to do for your baby?

Banking placental blood in addition to cord blood doubles the number of segments preserved and increases the total number of stem cells available. This is important for two reasons. First, transplanting more stem cells has been shown to increase the probability of transplant success and survival if needed. Second, having multiple segments available may offer the potential to treat additional conditions that may affect your baby and/or other close family members. Whether this child is your first or an addition to your family, you want to do everything you can to provide for your newborn’s well-being now and in the future. Cord blood and placental blood and tissue banking provides you with the ability to collect and preserve potentially lifesaving stem cells and bank even more stem cells. This is accomplished by collecting them from two usable sources of stem cell-rich blood: the umbilical cord and the placenta. And, doing so could one day save the life of your child or a close family member.

FemmPro OB/GYN believes that banking the most stem cells may ensure the best possible outcome for your child or family member in case there is a need for a future transplant. Your doctor simply takes the blood and tissue in a special LifebankUSA collection kit and is sent to their local processing and storage facility in New Jersey.

With LifebankUSA, you also have the option to donate the umbilical cord and placenta to contribute to lifesaving medical breakthroughs that will help save lives through research and transplantation. LifebankUSA accepts donations from any hospital nationwide. So, please consider donating cord blood and placenta to help save lives, even if you make a personal decision not to pursue private banking.

For more information and enrollment, consult with your FemmPro OB/GYN Professional or visit www.LifebankUSA.com .

What is pen test (penetration testing)? Definition from #open #source #penetration #testing


pen test (penetration testing)

Penetration testing (also called pen testing) is the practice of testing a computer system, network or Web application to find vulnerabilities that an attacker could exploit.

Pen tests can be automated with software applications or they can be performed manually. Either way, the process includes gathering information about the target before the test (reconnaissance), identifying possible entry points, attempting to break in (either virtually or for real) and reporting back the findings.

The main objective of penetration testing is to determine security weaknesses. A pen test can also be used to test an organization’s security policy compliance, its employees’ security awareness and the organization’s ability to identify and respond to security incidents.

Penetration tests are sometimes called white hat attacks because in a pen test, the good guys are attempting to break in.

Pen test strategies include:

Targeted testing
Targeted testing is performed by the organization’s IT team and the penetration testing team working together. It’s sometimes referred to as a lights-turned-on approach because everyone can see the test being carried out.

External testing
This type of pen test targets a company’s externally visible servers or devices including domain name servers (DNS), e-mail servers, Web servers or firewalls. The objective is to find out if an outside attacker can get in and how far they can get in once they’ve gained access.

Internal testing
This test mimics an inside attack behind the firewall by an authorized user with standard access privileges. This kind of test is useful for estimating how much damage a disgruntled employee could cause.

Blind testing
A blind test strategy simulates the actions and procedures of a real attacker by severely limiting the information given to the person or team that’s performing the test beforehand. Typically, they may only be given the name of the company. Because this type of test can require a considerable amount of time for reconnaissance, it can be expensive.

Double blind testing
Double blind testing takes the blind test and carries it a step further. In this type of pen test, only one or two people within the organization might be aware a test is being conducted. Double-blind tests can be useful for testing an organization’s security monitoring and incident identification as well as its response procedures.

Testing an WebAPI app in memory – david whitney, agile – software


One of the nice things around the rising tide of OWIN in the .NET ecosystem is that it literally supports пїЅhosting anywhere пїЅ as long as thereпїЅs a viable host!пїЅ. For fans of TDD, the great thing about this is пїЅanywhereпїЅ includes пїЅinside your unit testsпїЅ.

This lets you build a really powerful development workflow where you can lean entirely on your test runner while building your APIs, and not have to bother with the painful cycle of breaking out into external tools. You get to execute the entire WebAPI stack, from inside your acceptance or unit tests and get rapid feedback.

This only works if youпїЅre using WebAPI hosted пїЅusing OWINпїЅ, and allows you to write tests that look like this:

Combined with manipulation of your container registrations, you can execute full stack tests with a single mocked out component like your data store like this:

Powerful right? Lets take a look at how we put this together over a vanilla WebAPI controller, with a single DIпїЅd dependency.

WeпїЅre going to use a few nuget packages пїЅ the ones provided by Microsoft to host OWIN components in IIS, some testing helpers that support in process hosting of OWIN components outside of IIS, and Ninject an IoC container.пїЅ We have a packages.json that looks like this:

Our solution looks like this:

There are a couple of important pieces here пїЅ the WebAPI app with itпїЅs OWIN Startup file, a Ninject dependency resolver to hook up IoC into WebAPI, and the controller described earlier. In addition to this we have the interface IGetValues implemented by ValueService. For this example, ValueService is very simple:

Your OWIN startup class is effectively your пїЅGlobal.asaxпїЅ пїЅ it bootstraps your app and configures components.

YouпїЅll see that weпїЅre configuring routes, creating a new Ninject пїЅStandardKernelпїЅ IoC container, and using the Ninject.Extensions.Conventions library to bind up all our components пїЅ in this case just our IGetValues service. IпїЅll skip over the implementation of the Ninject dependency resolver, but all it does is delegate calls to create components to the Ninject standard kernel.

Pressing F5 in Visual Studio will launch the WebAPI app in IIS Express, and you can visit it in a browser

Now we have a working WebAPI app, lets see how we can test it in memory. We want to build a test that runs the whole of the WebAPI stack in memory, and asserts on its response.

To do this, we need to use a couple of packages пїЅ the Microsoft Owin HttpListener package, the Owin Hosting package and Owin testing package, alongside our test framework (NUnit).

With those packages installed, we can write a test that wires all these components together.

What weпїЅre doing here is using the Owin hosting components to invoke our apps Startup class, hosted over HttpListener, on localhost on the port 8086. WeпїЅre then using a regular HTTP client to connect to this server, execute a request, and assert on a response. ItпїЅs a small marvel that we can do this at all, but TDDers will be cringing at the amount of noise in the test distracting you from the meaningful parts of your test пїЅ the preconditions and assertions. We can do better than this!

A Less Noisy Approach

Consider this class

Firstly, itпїЅs a base class that tidies all the noise out of the way пїЅ all the boilerplate code is moved into a test fixture setup and teardown, and weпїЅre detecting the first available free port to ensure that tests written execute on any machine theyпїЅre executed on. Using this class, our previous test becomes

instantly becoming readable and exposing only the things we really care about in the test пїЅ what weпїЅre asking our code to do, and what the response is. We can pretty much use this base class everywhere because itпїЅs bootstrapping our entire application for each text fixture.

Given how hard itпїЅs previously been to test the full ASP.NET web stack, this is a revelation пїЅ you can write full stack acceptance tests without an installed web server, and with no additional infrastructure or support.

In real world examples your application likely has many components that connect to and use external resources (databases, web services) that youпїЅll want to isolate and replace with test doubles. With some creative use of our IoC container, we can get the best of both worlds and execute full stack acceptance tests (because at this point, weпїЅre definitely not пїЅunit testingпїЅ) while swapping out пїЅjustпїЅ your data access component or пїЅjustпїЅ an API client library to provide fake responses.

To do this, we want to rebind parts of our application stack for each test, and luckily, Ninject (and pretty much any other good container) makes this quite easy. Consider the following additions to our base class

ItпїЅs a little bit long winded, but what weпїЅre doing is maintaining a dictionary of Mock objects (using Moq) and providing some helper methods for use in our unit tests. When a unit test calls the method пїЅMockOutпїЅ a mock is generated and returned for the test to use. This Mock is пїЅfrozenпїЅ for the duration of the test fixture and rebound into our IoC container.

What this means is that we can bootstrap our entire stack, and then re-register a single component to a Mock, letting us manipulate a single external resource. This becomes exceptionally useful in our broad acceptance tests

Here you can see weпїЅre replacing the implementation of IGetValues with a mock that returns a known value, and asserting that the full stack call returns a body with that value in it. The test is synthetic, but the application is very real пїЅ you could mock out API calls to third parties, mock out your entire data store or a single component and verify the full execution of your entire system.

These broad acceptance tests, combined with unit tests of individual components give you the perfect mix of high level пїЅfeature focusedпїЅ tests (you can add a BDD framework of choice if thatпїЅs your thing) that assert on behaviour not implementation and regular пїЅTDD Unit TestsпїЅ around the components that your system is composed from.

There are lots of parts of ASP.NET vNEXT that are пїЅcoming soonпїЅ or пїЅwait and seeпїЅ, but the community effort around OWIN and the maturation of some of the middleware frameworks makes this a technique you can and should adopt now.

5 Responses to Testing an ASP.NET WebAPI app in memory

While not quite as completely end to end as the solution you have provided, you can also assign an HttpServer instance to be the HttpMessageHandler of an HttpClient, which allows you to use an HttpClient in exactly the manner you have described here, but without using any system resources to bind the site to an actual port (which has a happy side effect of not requiring you to run the tests as an administrator). Additionally, this lets you test sites which are not currently OWIN-hosted.

Really nice solution.

Question though. if your api uses the Authorize attributes how can we implement this with inmemory testing?

Hi. Have you ever had an issue where you ran a test suite and only the first test passes and the rest fail with test server returning 500 internal server error? How can I debug the 500 error?

if your api uses the Authorize attributes how can we implement this with inmemory testing.
No answer?

If you need a mocking server, you can take a look at WireMock.Net. https://github.com/StefH/WireMock.Net

This is a C# .NET version which mimics the functionality from http://WireMock.org

Brucelle Arizmendi


After having the opportunity to test the Virtual Hacking Labs, I must admit that the VHL Labs are challenging-fun, awesome and unique in its own way. I find it challenging, intriguing and inspiring at the same time. Great work by the VHL Team.

Kgomotso Pule

CEH, Information Security Analyst

The courseware is one of the most comprehensive that I’ve ever come across. It’s very easy to understand and follow! Recommended for anyone starting with no prior knowledge of the subject of ethical hacking. Great job, VHL.

Latest News

Many people have asked me what are the best hacking tools and which tools they should use for penetration testing. Not a strange question considering the fact that there are so many different hacking tools around. Getting started with the right toolset makes penetration testing much more fun and approachable for new comers. Therefore I created a list of the most popular and commonly used penetration testing tools.

Today it has been 4 weeks since the official launch of the Virtual Hacking Labs. In the last 4 weeks we ve had the honour to welcome the first students in the Virtual Hacking Labs. We are very excited to see that the hacking labs have drawn attention from both beginners and experts in the field of penetration testing. We also appreciate the positive feedback we ve got from both groups.

Today we have finally launched the Virtual Hacking Labs for the public! After almost a year of hard work we can offer our students a full self paced penetration testing course that includes lab access to 30 machines that are vulnerable by design. All lab machines have been carefully developed by us in such way that they contribute to a specific learning experience. Learn about exploiting SMB vulnerabilities, SQL injection, SNMP enumeration, code analysis, reverse shells and Metasploit in the courseware and practice techniques in the Virtual Hacking Labs.

Load Testing Web Services with soapUI #soapui #load #testing


Load Testing Web Services with soapUI

There are many tools available for testing web services. One of the ones we use that’s easy and has a fairly rich set of features is soapUI (did I mention that it’s also free and open source). With this tool you can easily test SOAP or RESTful services either by manually adding the links and messages, or via a WSDL or WADL utilizing their import feature. In either case, entering a request and receiving a response is a fairly trivial task and for purposes of time, will not be discussed here. You can find more information on how to get started with soapUI on their website .

Setting up a Test Suite

Another capability of soapUI that you might not know about is the ability to setup Test Suites for automated Unit Testing and a step beyond that, actually running simulated Load Tests for your web services. Setting up a Test Suite with a Test Case is as simple as right-clicking on an existing request and selecting “Add to Test Case”. When the dialog appears, you can either pick an existing Test Suite or add a new one. The Test Case editor will then appear and let you configure the Test Case with the request details (input message, headers, etc.) and the Assertions you want to perform. soapUI allows quite a few options for how to build the assertions such as XQuery, XPath, contains, not contains, schema compliance, and SLA Response. More details on how to setup test cases can be found here .

For example, a simple Test Case should have some assertion(s) that check the response message for correctness and another for the SLA Response Time. So perhaps one of your assertions could use an XPath expression to test the number of XML nodes returned or maybe the content of the JSON response. Setting up an SLA Response Time assertion is pretty straight-forward but is significant if you are running load tests and it requires some thought as to how long each Test Case should run. If you have a service request that is hitting the database using a primary key search, this should be much faster than one that uses wildcards. These types of scenarios should be considered when determining the desired response time. Once you setup your assertions and request details, you can run your Test Case to make sure it passes. Run it several times and check out the “Request Log” tab to get an idea of the SLA Response Time and adjust the assertion if necessary.

Load Testing

Once you have your Test Suite setup with at least one Test Case, you can perform a Load Test; this is where you find out how your service is handling a lot of messages all at once. To create a Load Test, you simply right click on the Load Tests option under the Test Suite and then select “New Load Test”. Once you get to the Load Test Editor screen you will see that it was nice enough to add all of your Test Cases (or Steps) to the new Load Test. Now you can configure the Load Test to setup how long it will run, how many threads, the delay between requests, and the strategy (this drives more test options depending on which you choose). soapUI offers several load testing strategies which simulate different scenarios and types of load. Here are a few of the ones you might want to try (you can find a detailed list here ):

  • Simple – Runs a specified number of threads using a randomized delay between requests. This is good for setting a baseline for performance of your service. Run this test first to make sure you’re service is performing well under normal circumstances.
  • Variance – Runs a varied number of threads in a “sawtooth” (randomly increasing/decreasing number of threads; think of an ECG line of your heartbeat). This is good for stress testing and potentially baseline testing based upon what you believe will be “normal” load on your service.
  • Burst – Runs a specified number of threads all at once for a specified amount of time, then waits until the next “burst” to begin based off the set delay. This is good for recovery testing, i.e. if you service is completely slammed, how does it react.

Putting your Service to the Test

Once you have a load test setup, the challenge becomes setting the thresholds for your service that will help to meet the desired SLA Response Time. This means different things for different applications. In a Java or .NET application, it might mean adjusting the number of threads running in parallel. It could also mean you need more hardware (i.e. Memory, CPU) to handle the expected load. Whatever the case may be, it is always fun (and useful) to get a before and after snapshot of the performance of the service. This way you can make sure your changes actually worked!

In the following example, we have hosted HTTP RESTful Services using IBM’s Message Broker (version 7). Message Broker makes it very easy to scale the number of threads by adjusting the number of additional instances of a flow that is deployed into the runtime. Each instance of the flow is essentially an additional thread that can be utilized for handling requests. The default is 0 additional instances which means, in this case, only one (1) HTTP request can be handled at a time. When you hit the service with multiple threads, the subsequent threads will wait for the previous one to finish. As you can see, this is not a good setup for a production web service:

You can see in the image above that during a 60 second time period, 51 runs of the Search_ById service resulted in an assertion error which, in this case, is because it did not meet the SLA response Time. This is simply using the default settings of the Simple Test strategy which this should not be a problem for a typical service to handle. At this point, running any other testing strategy is pointless until we figure out how to make some pretty drastic changes to the service. So we will increase the number of instances of the flow in Message Broker to 5 and re-run our test:

After this change, you can plainly see that the service handled the load much better. There was only 1 error and the SLA set on the “by Id” search is pretty aggressive, so even the max response of 2,347 milliseconds is still acceptable. You can also see that it executed 236 more tests in the same 60 second time period. This is because the requests did not have to wait for the previous request to finish. This service is now acceptable to run in a production environment. Just for fun, let’s try the service with a more aggressive test strategy and see how it does:

In this scenario, we started with 8 threads, set the interval to 60, and the variance to 0.8 which means the number of threads will increase from 8 to 14 within the first 15 seconds, then decrease back to 8 and continue down to 2 threads after 45 seconds, and finally go back up 8 after 60 seconds. You can see that the service performed fairly well overall during this test. We might want to raise the expected SLA on the “by Id” search service to a little less aggressive number, but again, 1,968ms for the max response is acceptable.

Taking it a Step Further

With the latest release of soapUI, you have the ability to run the load tests out of another tool called, loadUI. This tool uses the Test Suite and Load Tests you have setup in soapUI to run the tests but provides much more detail and better graphs and charts to analyze your results. I have not used this tool, but the soapUI website recommends using it for benefits such as distributed tests in real-time, better UI, scalable testing, live analytics, and more. It is free and open source and integrates seamlessly with soapUI, so why not give it a shot? If you have already used loadUI or decide to try it out, leave some feedback below.

Security Assessment, VAPT, ECSA Training in Bangalore, Chennai, Mumbai, Pune, Delhi, Gurgaon,


A penetration test is done to evaluate the security of a computer system or network by simulating an attack by a malicious user / hacker. The process involves active exploitation of security vulnerabilities that may be present due to poor or improper system configuration, known and / or unknown hardware or software flaws, or operational weaknesses in process or design.

This analysis is carried out from the position of a potential attacker, to determine feasibility of an attack and the resulting business impact of a successful exploit. Usually this is presented with recommendations for mitigation or a technical solution.

About this workshop

3 Quick Statnamic Facts 21 Statnamic devices world-wide
12 Statnamic testing companies Over 1200 contract Statnamic load tests performed in 16 countries – more than one test every day, somewhere in the world! Over 80 published papers, including papers from 2 International Statnamic Seminars More than 10 Universities currently researching Statnamic (USA – Auburn, USF, BYU, Umass, John Hopkins, plus others) Acceptance by 16 State DOT’s in the US, US Army Corps of Engineers, FHWA, and Japanese Geotechnical Society





12 The Idea Statnamic Note: The JGS defines a Rapid Load Test as 5 tr 500, where tr is the number of times a stress wave will travel up and down the pile during the loading event

13 Inertial Load Testing (Bermingham – 1987)
This type of test was clearly different from a Dynamic Load Test A NEW WORD WAS REQUIRED. Inertial Load Testing (Bermingham ) STATNAMIC (Middendorp – (1989)) Pseudo-static (Fundex PS PLT – early 1990’s) Kinetic (Holeyman ) Rapid Load Test (Japanese Study Group ) Transient Long-period (Janes -1997) Slow dynamic (Goble, Rausche ) others – impulse, kinematic, push, etc.

14. a global perspective. In March of 2000, the Japanese Geotechnical Society added “Rapid Load Testing” to their national standard for pile testing. In the year 2000, it is estimated that there will be more than 500 Statnamic Load Tests on foundations around the world.












40 Lateral Test Programs in the US
New Bern, North Carolina DOT (50 tons) Brigham Young University – (200 tons) Utah DOT & CALTRANS Auburn University, Alabama – (250 tons) (FHWA) Pascagoula, Mississippi DOT (800 tons, over-water) Providence, Rhode Island DOT (400 tons, over-water) San Juan, Puerto Rico Trans Authority (400 tons) New Bern, North Carolina DOT (1200 tons, over-water)

42 Foundation Types Tested in the USA Using Statnamic
Drilled Shafts tested up to 3500 tons laterally and axially Driven Piles (all types) Pile Groups tested laterally and axially Stone Columns Auger-Cast Piles conventional and ‘displacement’ types Spread Footings and Plates Other types of “Ground Modification”

43 Background Statnamic Theory and Analysis
GOAL: to derive the STATIC load displacement behavior from a STATNAMIC load test (usual goal for axial compression testing)

47 Physical Model m c k F u In a STATNAMIC LOAD TEST:
F = Applied force from the Statnamic device (measured by a load cell) m = Pile mass (easy to calculate) c = pile/soil damping (UNKNOWN) k = pile and soil stiffness (the term we need to find) u, v, a = measured by an optical sensor and/or accelerometer

48 Physical Model F = ma + cv + ku GENERAL LIMITATIONS:
This equation makes the following assumptions: 1. Inertia (mass x acceleration) – assumes that a single value of ‘m’ (the pile mass) represents all of the moving mass in the system 2. Damping (damping coefficient x velocity) – assumes that a single value of ‘c’ is valid throughout the entire load test, and that the damping force is directly proportional to velocity 3. Stiffness (stiffness coefficient x displ.) – the calculated stiffness is the stiffness of the pile and soil system under a RAPID load – no correction is made for long-term, time-dependent pile behavior, which includes effects such as changes in pore-pressure and creep F = ma + cv + ku

50 Physical Model F = ma + cv + ku c m k F u EQUATION OF MOTION:
This equation describes the equilibrium between some forcing function and the 3 forces: Inertia (mass x acceleration) Damping (damping coefficient x velocity) Stiffness (stiffness coefficient x displ.) This equation forms the basis for describing the motion of any single degree of freedom system. F = ma + cv + ku

51 Analysis Assuming that stress-waves can be ignored, the analysis of a Statnamic Load Test is greatly simplified in comparison to a dynamic load test. Although stress-waves may be ignored, the ‘dynamic’ effects of INERTIA and DAMPING CANNOT! Result: a detailed model, which includes pile and soil properties IS NOT NEEDED. A simple physical model can be used to remove the effects of damping and inertia from the measured signals – no information about the soil is needed, and subjective judgement is minimized.

Drill Pipe – Riser Cleaning #waterjetting, #water #jetting, #water #jetting #equipment, #water


Drill Pipe Cleaning

Aqua Energy are a market leader in manufacturing and supplying drill pipe and oil riser cleaning systems.

For manually cleaning pipes, box pins in different locations our diesel engine driven, 10′ foot, containerised unit, our skid mounted or trailer mounted units are ideal.

We manufacture a mobile semi-robotic drill pipe cleaner that is installed inside 20′ foot or 40′ foot container. Once on site two operators take several hours to set up the cleaning system. Once set up the semi robotic system should easily clean forty to eighty 48′ feet pipes inside and outside in an eight our shift.

For permanently situated inside pipe yards we manufacture and supply semi robotic or full robotic pipe cleaning systems.

Our very basic equipment will clean 20 to 30 drill pipes in an 8 hour shift and our fully robotic system can clean up to 130 (one hundred and thirty) 14.80 metre (48′ feet) long pipes, box and pins in the same 8 hour shift.

  • With our robotic equipment the customer has many options.
  • He can clean the pipe ID first and then clean the OD.
  • Or if he requires fast production, he can clean both the ID and the OD at the same time.
  • Plastic lined pipes are not damaged due to the variable pressures of the system.
  • Using 2,800 bar (40,000 psi) pressure we can clean the pipes, box and pins to a surface finish suitable for NDT inspection.
  • With our larger pumps removing hard concrete or cement from the pipes is not a problem.
  • With our system there is no requirement for abrasive bead blasting.
  • NORM Scale is easily removed.
  • Our Riser cleaning equipment is the fastest on the market.

Please visit our YouTube channel for videos of our equipment in operation.

The above risers are being cleaned with our Model: DC-400, 20′ foot containerised unit.

Pipe Cleaning

This image is of our Model: DT-60-ST, Diesel Engine Driven, Trailer Mounted, Low Pressure Pipe Cleaning Unit.

The small 50 horsepower pumps are driven with 61 horsepower engines and are ideal for removing sand, silt and light rust from 8″ metal pipes.

The DT-60-ST has twin water tanks that hold up to 1,000 litres of water and these are good for pipe yards that don’t have water readily available.

  • Pressures for this model range from 100 bar up to 600 bar.
  • Water flow from 30 litres per minute up to 100 litres per minute.
  • Special build models can be supplied in 1,500 bar up to 2,500 bar.

The photo shown is in the Maldives in the Indian Ocean where the customer purchased two of these small units specifically for pipe and sewer cleaning.

Citrix: Edgesight for loadtesting best practices – My Virtual Vision #citrix #edgesight


My Virtual Vision

Citrix: Edgesight for loadtesting best practices

I ve been involved with quite a few Citrix XenApp/XenDesktop projects and a reoccurring phase in all of these projects is scaling/load testing. When starting a project there s a initial phase where you try to give an answer to all of the questions concerning scalability and sizing. So I ve build a load test a couple of times now, the problem with these load tests is that no load test is equal to another. Every company has it s own applications, settings and user types thus these load tests are custom made and can be re-used only partly for other customers.

Citrix offers EdgeSight for loadtesting when you buy the right Citrix XenApp licenses (See load testing services ):

At one of my recent projects I had to write a load testing script containing an average user with average applications . My first problem was to define what an average user is for this organization. The second problem was to define what the average applications where for this average user. To tackle this problem I had a couple of meetings with key users (which normally aren t average users btw), application admins and the sys admins. That s when I created a matrix of users and their generated workload based on the outcome of these meetings. The applications where fairly easy to determine, the core applications for the different users where chosen and based on input of users and sys admins we decided to use that certain applications.

The start of the project was to determine what to test and the user type (work load). After this we should determine what we want to measure. In a best practices document for XenDesktop I found the following parameters:

1 Provisioning Server Process

2 Desktop Delivery Controller Process

Is this what you need to monitor for your own environment? It depends, it covers a great deal of the most important parameters but you ll still need to fine tune your own dataset and need to analyze the outcome.

So the most important things you ll need to know when defining a load test:

  • What applications do I want to test?
  • At what load should these applications be tested?
  • What parameters do I need to analyze?

A couple of tips while writing the load tests:

  • Make sure you have a description of the steps you want to test. Create manuals for user actions so you can reproduce the load test and are able to show what you ve tested, even after a couple of years (create a baseline).
  • Define the load, create different load profiles for the different types of users.
  • Install Operating System Updates and make sure driver installations are finished.
  • Ensure that any environment-specific changes are made to the golden image at the start. Disk cache optimizations, memory usage limitations and firewall settings are just a few examples. Also ensure that local and domain policies will work as-planned.
  • Tackle First-Time User Log Ons so that the load test will be completed successfully.
  • Build your load test fool proof, use the windows shortcut keys as much as possible. Make sure timing is right!
  • When recording the load test Edgesight will record the name of the screens, make sure these are anonymous otherwise the script will fail while checking the screen names and expecting another value.
  • Make sure that all of the users used for the test can access the applications and run the processes defined to that user type.

This will probably can be used on all types of load testing so you can use it while preparing for any load testing software and if you ve got additional comments on preparing for. and conducting load testing please let me know and I will add them!

Test Automation Tools – Popular Automated Testing Tools and Software #test #automation,


Software Test Automation Tools

Automated software testing is becoming more and more important for many software projects in order to automatically verify key functionality, test for regressions and help teams run a large number of tests in a short period of time. Many teams (especially larger projects) still require a significant amount of manual functional testing in addition to automated testing, either because of the lack of sufficient resources or skills to automate all tests.

There are various tools that help software teams build and execute automated tests. Many teams are actively using unit tests as part of their development efforts to verify critical parts of their projects such as libraries, models and methods. Historically, testing user interfaces of desktop-based applications via automated tests have been more challenging, and currently available tools for this are usually commercial and quite expensive.

With the growing number of web-based applications this is changing, however, as verifying and testing web-based interfaces is easier and there are various tools that help with this, including free open source projects. Please see below for a list of popular and useful tools, projects, books and resources to get started with automated software testing.

Automated Web Testing Tools 7 Tools

Automatically testing your web application is a good way to ensure that new versions of your application don’t introduce bugs and regressions. Automation of your web application testing also allows your development team to make changes and refactor code with more confident, as they can quickly verify the functionality of the application after every change.

However, actually building automated tests for web applications can be challenging because the user interface of your application might change regularly, because of incompatibilities between browsers and because you usually need to support various server or client platforms. The following tools make it easier to build and execute automated tests for your web application.

Selenium is a popular automated web testing tool and helps you automate web browsers across different platforms. Selenium has the support of some of the largest browser vendors who have taken steps to make Selenium a native part of their browser.

Watir is a set of Ruby libraries for automating web browsers and allows you to write tests that are easy to read and maintain. Watir drives browsers the same way people do (it clicks links, fills in forms, presses buttons etc.) and also checks results such as whether expected text appears on the page.

Windmill is a web testing tool designed to help testers automate and debug web applications. It comes with a cross-browser test recorder, JavaScript integration and an interactive shell to automate web browsers.

Atomic Force Microscopy (AFM)

Atomic Force Microscopy (AFM)

Atomic Force Microscopy

Description of Technique

Atomic Force Microscopy (AFM) is a form of scanning probe microscopy (SPM) where a small probe is scanned across the sample to obtain information about the sample’s surface. The information gathered from the probe’s interaction with the surface can be as simple as physical topography or as diverse as measurements of the material’s physical, magnetic, or chemical properties. These data are collected as the probe is scanned in a raster pattern across the sample to form a map of the measured property relative to the X-Y position. Thus, the AFM microscopic image shows the variation in the measured property, e.g. height or magnetic domains, over the area imaged.

The AFM probe has a very sharp tip, often less than 100 Å diameter, at the end of a small cantilever beam. The probe is attached to a piezoelectric scanner tube, which scans the probe across a selected area of the sample surface. Interatomic forces between the probe tip and the sample surface cause the cantilever to deflect as the sample’s surface topography (or other properties) changes. A laser light reflected from the back of the cantilever measures the deflection of the cantilever. This information is fed back to a computer, which generates a map of topography and/or other properties of interest. Areas as large as about 100 µm square to less than 100 nm square can be imaged.

Analytical Information

Contact Mode AFM – The AFM probe is scanned at a constant force between the probe and the sample surface to obtain a 3D topographical map. When the probe cantilever is deflected by topographical changes, the scanner adjusts the probe position to restore the original cantilever deflection. The scanner position information is used to create a topographical image. Lateral resolution of

Intermittent Contact (Tapping Mode) AFM – In this mode, the probe cantilever is oscillated at or near its resonant frequency. The oscillating probe tip is then scanned at a height where it barely touches or “taps” the sample surface. The system monitors the probe position and vibrational amplitude to obtain topographical and other property information. Accurate topographical information can be obtained even for very fragile surfaces. Optimum resolution is about 50 Å lateral and

Lateral Force Microscopy – This mode measures the lateral deflection of the probe cantilever as the tip is scanned across the sample in contact mode. Changes in lateral deflection represent relative frictional forces between the probe tip and the sample surface.

Phase Detection Microscopy – With the system operating in Tapping mode, the cantilever oscillation is damped by interaction with the sample surface. The phase lag between the drive signal and actual cantilever oscillation is monitored. Changes in the phase lag indicate variations in the surface properties, such as viscoelasticity or mechanical properties. A phase image, typically collected simultaneously with a topographical image, maps the local changes in material’s physical or mechanical properties.

Magnetic Force Microscopy – This mode images local variations in the magnetic forces at the sample’s surface. The probe tip is coated with a thin film of ferromagnetic material that will react to the magnetic domains on the sample surface. The magnetic forces between the tip and the sample are measured by monitoring cantilever deflection while the probe is scanned at a constant height above the surface. A map of the forces shows the sample’s natural or applied magnetic domain structure.

Image Analysis – Since the images are collected in digital format, a wide variety of image manipulations are available for AFM data. Quantitative topographical information, such as lateral spacing, step height, and surface roughness are readily obtained. Images can be presented as two-dimensional or three-dimensional representations in hard copy or as digital image files for electronic transfer and publication.

Nanoindentation – A specialized probe tip is forced into the sample surface to obtain a measure of the material’s mechanical properties in regions as small as a few nanometers. (See the Handbook section on Nanoindentation Hardness Testing .)

Sample Requirements

No sample preparation is typically required. Samples can be imaged in air or liquid. Sample height is limited to about 1.5 inches. Areas up to 8 inches in diameter can be fully traversed without repositioning. Larger samples can be fixtured for imaging within a limited area. Total surface roughness in the image area should not exceed about 6 µm.

Typical Applications

  • 3-dimensional topography of IC device
  • Roughness measurements for chemical mechanical polishing
  • Analysis of microscopic phase distribution in polymers
  • Mechanical and physical property measurements for thin films
  • Imaging magnetic domains on digital storage media
  • Imaging of submicron phases in metals
  • Defect imaging in IC failure analysis
  • Microscopic imaging of fragile biological samples
  • Metrology for compact disk stampers

Under these regulations, you must have a certain type of mechanical experience before the F.A.A. will allow you to take the F.A.A. written exams. The required experience for the powerplant mechanic rating is a minimum of 18 months working with tools on any type of aircraft engine. The required experience for the airframe mechanic rating is a minimum of 18 months working with tools on any type of airframe. If you want both ratings, and your experience was a combination of airframe and powerplant, then you need a total of 30 months experience (not 36).
Obtaining Your Authorization Slips
To be enrolled in GLOBAL SCHOOL OF AERONAUTICS as a mechanic student, you must first meet the F.A.A. experience requirements. The purpose of this is to be sure the F.A.A. will permit you to take the written exam after you finish the course.
Oral and Practical Examinations
The F.A.A. requires the written results to be in the student’s hands before an Oral and Practical examination may be given. Therefore, in order to take an oral and practical examination with one of our examiners, you must bring your written score slips and your airmen certificate and/or rating application 8610-2. Your F.A.A. inspector should give you two copies of the 8610-2 form, both bearing original signatures. Photo copied signatures are not accepted.
Classroom Time
The average time to obtain the A P rating is from 11 – 13 days. Our instructors work closely with each student, progressing him/her based on their own capabilities. Our course is guaranteed 100% – we keep working with you until you pass – good for 36 months.
