Requirements Modeling Framework. The Requirements Modeling Framework (RMF) is an open-source software framework for working with requirements based on the ReqIF standard. RMF consists of a core allowing reading, writing and manipulating ReqIF data, and a user interface allowing to inspect and edit request data.

RMF is the first and, currently, the only open-source reference implementation of the ReqIF standards. Noteworthy is the fact that RMF has already been deployed in the ProStep ReqIF Implementor Forum in order to ensure the interoperability of the commercial implementation. Since 2011 there have been reports in the German and in the international press about RMF.

History 

RMF has been in development under the name ProR since 2009 in the scope of the DEPLOY research project, collaborative efforts quickly developed with the research project Verde resulting in significant acceleration of development. At this point, the data model is based on RIF, the predecessor of ReqIF.

In June 2011, a proposal was created to transform the code into an Eclipse Foundation project. This proposal was adopted in November 2011. A part of the migration to the Eclipse Foundation was the conversion of RIF to the current version of ReqIF 1.0.1.

In the spring of 2012 DEPLOY and Verde opted out of the research projects. Nevertheless, RMF keeps on evolving, within the framework of the research project Advance. From Formal Mind free extensions to ProR under the name ProR Essentials are developed.

Currently neither version 0.14 nor 0.13 can be integrated into the latest version of eclipse, neither ProR nor RMF. Only version 0.10.0 remains, reasons for that are unknown. Version 0.13 (from the release folder) and version 0.14 (from the latest folder) can be integrated into eclipse version "Mars.2 Release (4.5.2)".

Functionality 

The RMF core allows for storing, writing, validating and manipulating ReqIF files. The manipulation of data is implemented programmatically using EMF.

ProR additionally enables the interactive creation, inspecting and editing of ReqIF models. The requirements are then presented in configurable tables. Links between requirements can be created via Drag & Drop, or through context menus.

Integration with other tools 

ProR is designed for integration with other Eclipse-based tools. There is an extension point available, which makes it possible to integrate other available renderers and editors, or to react to Drag & Drop events from outside.

As part of DEPLOY and Advance, the integration of Event-B models was developed.

The TOPCASED -project has now, as suggested, integrated RMF.

Further integrations have been proposed or implemented in a prototype.

Thermal center. The thermal center is a concept used in applied mechanics and engineering. When a solid body is exposed to a thermal variation, an expansion will occur, changing the dimensions and potentially the shape of the body and the position of its points. Under certain circumstances it may happen that one point belonging to the space associated to the body has no displacement at all: this point is called the thermal center (TC).

Applications
The thermal center position is not affected by a thermal expansion: this property makes the TC a very interesting point in those applications where it is important that thermal variations have no effects on a certain process. Photolitography machines and high precision optical instruments are some examples of application of this concept.

Definition

The thermal center is defined under the following hypothesis:
A solid body with homogeneous and isotropic thermal properties;
Isostatically constrained;
A thermal variation ΔT is applied to the entire body.

The thermal variation will produce an expansion of the body: this means that for each couple of points P and Q the distance will become:

where ,  is the coefficient of thermal expansion.
Analyzing this phenomenon in an absolute coordinate system, the transformation of the solid body is a geometrical similarity.
It is possible that, choosing the constrains conveniently, one point belonging to the space associated to the body will not move during the thermal variation: this point is called thermal center. In this case, the geometrical similarity becomes a homothety and the thermal center is the center of the homothety itself.
 
The thermal center does not always exist. The TC is a function of the constraints. Picture B shows an example where the geometry of the constraints doesn't come to a unique point.

The TC may exist even if the body has non-homogeneous isotropic thermal properties, but when this condition is not verified, it's not possible to determine its position by using the simple geometric method shown above, and the transformation will not be a homothety.

Shurly & Dietrich. Shurly & Dietrich Co. was a Canadian saw manufacturer that was founded in 1873 by Cosmos J. Shurly (1835 - 1918) and Jerome C. Dietrich (1838 - 1925). Shurly & Dietrich saws were heavily used in the Canadian logging industry.

History 

In 1873, Jerome Dietrich and Cosmos Shurly brought skills learned while working at Disston Saw Works in Philadelphia, Pennsylvania, and invested $12,000 to found the Shurly & Dietrich Co. They hired nine saw makers from Rochester, New York and Sheffield, England and began to manufacture saws in Galt, Ontario, now called Cambridge. By 1886 the company employed 70 skilled workman. The company held a number of Canadian patents for saw design.

By 1906, Cosmos' son Theodore Shurly was the factory superintendent.

Shurly & Dietrich later expanded into Quebec by purchasing an existing saw factory, Beaver Saw Works, in Sherbrooke.

Between 1904 and 1910 the company expanded its original Galt factory, but in 1914 it sustained damage from a fire. By that time they had also built another plant in St. Catharines.

In 1931, Shurly & Dietrich merged with another saw manufacturer, E. C. Atkins of Hamilton, and became Shurly-Dietrich-Atkins.

During World War II, Shurly Dietrich produced about 40,000 tons of light armoured plate, bringing in workers from Newfoundland to supplement the workforce.

In 1957, Shurly Dietrich was one of two main saw manufacturers in Canada. By 1968 about 1,400,000 feet of band saw blades designed for cutting metal and over 1,000,000 jigsaw blades were being manufactured each year.

In 1969, Shurly Dietrich was acquired by H.K. Porter.

In 1973, Shurly Dietrich closed its plant after one hundred years in business.

Turned, ground, and polished. Turned, ground, and polished (TGP) is a classification of finishing processes often used for metal shafting. Turning (on a lathe) creates straight round bars without the strain induced by cold drawing, while grinding and polishing improves the surface finish and roundness for high dimensional accuracy. Extreme straightness is critical in high-speed applications to prevent vibration and reduce wear on bearings.

Sparrow (target missile). The Sparrow (, ) target missile is an Israeli medium-range air-launched ballistic missile produced by Rafael Advanced Defense Systems. The missile is currently used as a target missile to test the Arrow anti-ballistic missile system. The missile has a modular warhead section and is capable of carrying a high-explosive warhead.

Versions 
There are three versions of the missile: Black Sparrow, Blue Sparrow, and Silver Sparrow. The Silver Sparrow version is designed to simulate Iranian Shahab-3 class ballistic missiles with a 1,500-2,000 km range. The Blue Sparrow has a total length of , weight of  and a range of  on a high ballistic trajectory.

The Rafael ROCKS stand-off range air-to-surface missile uses a Sparrow missile booster.

According to Petagon leaks concerning the october 2024 retaliatory strikes by Israel on Iranian military targets 16 Blue Sparrow based missiles with the previously unknown designation "Golden Horizon" were readied and cleared for use by the Israeli military.

Operational history
The Silver Sparrow version was first tested on September 2, 2013. The launch from the Mediterranean was detected by a Russian ballistic missile early warning radar at Armavir, followed by Israeli acknowledgement of the test over an hour later.

The Financial Times reported experts identifying the Blue Sparrow, from its booster remnants, as the missile most likely used in the 2024 Israeli strikes on Iran.

Following the Israeli retaliation leak, it is likely the ROCKS missile was used (sharing the same booster as Blue Sparrow) in the 2024 Israeli strikes on Iran.

DreamFactory. DreamFactory is an American software developer based in Las Vegas. It develops both commercial and open-source software that provides self-hosted integration and API generation services to multiple applications in cloud-based or on-premise environments.

History
DreamFactory was founded in 1998 by technology entrepreneur Bill Appleton. The company's flagship software, DreamFactory, was developed during his tenure as president of Cyberflix. The software was used in Cyberflix’s CD-ROM video game Titanic: Adventure Out of Time. DreamFactory began work on its foundation development environment in 2002. By 2004 they released their first product, SBuilder. Ultimately, DreamFactory sold a series of products on the SalesForce AppExchange including DreamTeam, SnapShot, OrgView, and Sbuilder. The product evolved over time until 2015, when the current iteration of DreamFactory first began in the current Github Repo. This new version of DreamFactory was built in Laravel and was originally entirely Open Sourced. The original team built a business model on only selling support, but by 2018 this business model failed. The company was sold, and the decision was made to close source some connectors and features.

Funding 
DreamFactory took on a $5.6 million Series A round of funding from New Enterprise Associates in 2006. Greg Papadopoulos, former chief technology officer at Sun Microsystems and a partner at NEA, sat on the DreamFactory board during this time.

In 2018, DreamFactory was acquired by Xenon Partners, a tech-centric private equity fund that has funded companies such as Right Signature, Dropbox, Packagecloud and Earth Class Mail.

Service 
DreamFactory’s core product is the same between Open Source and Commercial Versions. DreamFactory can run on Linux, Windows, and Docker and includes security controls and management services for Roles Based Access, API Key Management, Rate Limiting, Authentication, Logging, and Service-Side Scripting. The DreamFactory Scripting is in PHP, Python, and NodeJS.
