The ZwickRoell Group is a manufacturer of static testing machines and systems for materials and components testing used to evaluate the mechanical and physical properties and performance of materials and components. Core static tests carried out with this equipment includes tensile, compression, flexure (also referred to as bend), and cycling.
The company operates in 56 countries, has manufacturing facilities in Germany, UK and China, and strategic headquarters in the US and Singapore.
As of 2014 the Group employs 1250 staff in its international operations. It generates revenues of approximately 210 million euros.[1]
Zwick manufactures a range of testing systems for research and routine testing of materials and components. It has developed materials testing software, digital contact and non contact extensometry and pioneered robotic materials testing systems.
Roell & Korthaus have been involved in materials testing since 1920. Zwick began building machines and instruments for mechanical materials testing in 1937. The company founded by Professor Seger in 1876 evolved into the present-day concern Toni Techni. Roell and Korthouse, along with Toni Technik, have been part of the Zwick Roell Group since 1992.
In July 2001 the group become a corporation under the name of Zwick Roell AG, incorporating Zwick, Toni Technik and Indentec Ltd. Acmel Labo, the French manufacturer of laboratory instruments for the cement, lime and plaster industry, has been part of the group since May 2002. Zwick/Roell AG acquired the German company GTM in 2007 and Messphysik of Austria in 2006. In 2014 ZwickRoell opened its new factory in Taicang, China, some 50 km north-west of Shanghai. Here, on a site totaling around 2,000 m2, testing machines and instruments will be developed and assembled for the Chinese and world markets.[2]

Static application security testing (SAST) is used to secure software by reviewing its source code to identify security vulnerabilities. Although the process of checking programs by reading their code (modernly known as static program analysis) has existed as long as computers have existed, the technique spread to security in the late 90s and the first public discussion of SQL injection in 1998 when web applications integrated new technologies like JavaScript and Flash. Unlike dynamic application security testing (DAST) tools for black-box testing of application functionality, SAST tools focus on the code content of the application, white-box testing. A SAST tool scans the source code of applications and their components to identify potential security vulnerabilities in their software and architecture. Static analysis tools can detect an estimated 50% of existing security vulnerabilities in tested applications. In the software development life cycle (SDLC), SAST is performed early in the development process and at code level, and also when all pieces of code and components are put together in a consistent testing environment. SAST is also used for software quality assurance, even if the many resulting false positives impede its adoption by developers. SAST tools are integrated into the development process to help development teams as they are primarily focusing on developing and delivering software respecting requested specifications. SAST tools, like other security tools, focus on reducing the risk of downtime of applications or that private information stored in applications is not compromised.
Static load testing is an in situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower. Static load testings are performed in order to measure a design's axial tension or axial compression. It can also be used to measure its deflected shape under lateral load.
In software development, dynamic testing (or dynamic analysis) is examining the runtime response from a software system to particular input (test case). Tests can be run manually or via automation. Unit testing, integration testing, system testing, regression testing and acceptance testing are forms of dynamic testing. In contrast to static testing, the software must be runnable.

Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
