SS7 probe. An SS7 probe is a physical device to obtain signalling and/or bearer information from a telecommunications network, such as the PSTN or a corporate telephone system. The probe passively monitors the E1/T1 or SDH/SONET bearer channels, and extracts the signalling information for onward presentation to an application. A passive probe does not affect the network under observation—this is achieved through use of protected monitor points on the network distribution frames.

Applications 
The network application may be lawful interception  or a revenue-generating application such as missed call. Probes are also extensively used in operational support systems (OSS).

Applications served by probes include solutions for inter-carrier billing, revenue loss (by-pass/phantom traffic and analysis services), fraud prevention, billing, local number portability, quality of service, surveillance (global call trace), maintenance (protocol analysis), traffic engineering (link and trunk forecasting), alarming and SS7, Sigtran and IS-41 monitoring.

Passive monitoring probes provide a network and switch vendor-independent solution for network applications.

Lawful interception
Lawful interception concerns the delivery of calls and data to government approved reception centres. Interception is authorized through a legal framework, such as UK RIPA or US CALEA or Russia SORM.

Technology 
SS7 probe technology provides the correct physical interface to the telecommunications network. Opportunities for probing occur in both traditional TDM infrastructure as well as in ATM and IP networks. The different characteristics and infrastructure used for these interfaces is reflected in the types of interfaces to be monitored. These range from E1 or T1 2 Mbit/s or 1.5Mbs to SDH and SONET STM-x OC-x multiplexes.

Sd.Kfz. 4. The Sd.Kfz. 4 was a 4.5-tonne military truck of Maultier ("mule") half-track family developed during World War II by Germany. Its manufacturer designation was Mercedes-Benz L4500R.

Development
The Sd.Kfz. 4 was developed after the 1941 invasion of the USSR to deal with the ice and mud, which bogged down the wheels-only road-bound commercial vehicles that were used to supply German forces. It was a modified Standard Mercedes-Benz L4500S (4x2) with Horstmann suspension instead of a rear axle. Another manufacturer of 4.5-t truck, Büssing planned a similar conversion of its Büssing-NAG L4500S but did not proceed.

A total of 22,500 Maultier halftracks were produced by 1944, among which 1480 were 4.5-t. Sd.Kfz. 4, others 2-t. Sd.Kfz. 3. In 1943 Opel was directed to build armored vehicles outfitted with 15 cm Panzerwerfer 42 rocket launchers.  These vehicles were designated Sd.Kfz. 4/1, with around 300 produced. Given the extra weight of the Panzerwerfer, the top speed was only 24 mph (40 km/h). Another multiple rocket launching system, the 8 cm Raketen-Vielfachwerfer, was also fitted to the Sd.Kfz. 4 chassis.

The vast majority of Maultiers operated using British-pattern Carden-Loyd running gear, with the exception of the Type L4500R, which used PzKpfw. II running gear. The 6-cylinder engines were mated to a transmission with five forward gears plus reverse and could attain a maximum forward speed of 40 km/h. Each halftrack was equipped with the FuG Spr G f radio.

Aside from the Sd.Kfz. 4/1, the Sd.Kfz. 4 was armed only with a light 7.92 mm MG 34 or MG 42 machine gun with a traverse of 270° and elevation limits of -12° to +80°.

Dewvaporation. Dewvaporation is a novel desalination technology developed at Arizona State University (Tempe) as an energy efficient tool for freshwater procurement and saline waste stream management. The system has relatively low installation costs and low operation and maintenance requirements.

The process uses air as a carrier gas that transfers water vapor from ascending evaporative channels to adjacent, descending dew-forming channels. Heat flowing through the barrier allows the evaporative energy requirement to be fully satisfied by the heat released by condensation on the dew forming side. A small pressure difference is held so that the condensing cooler air is kept on the cool side.

Near atmospheric operation permits corrosion free and scale-resistant polypropylene construction, and also allows the use of low-grade heat to drive the process.

The process is proprietary, developed by Dr. James R. Beckman. Currently, Altela Inc. (Albuquerque, NM) is manufacturing this technology under the AltelaRain trade name.

Detailed process 
According to the Bureau of Reclamation, a branch of the US Department of Interior, this process uses simple corrugated plastic tanks with many "DewVaporation columns" inserted in each tank. Each column is made of corrugated plastic and is divided into two compartments. The wall in the middle serves for receiving and evaporating sea-water into a hot air stream, and on the other side for condensing freshwater. The cooling from the evaporation helps water condense on the dividing wall, while the energy from the condensing vapor, now turned to droplets, passes back to the evaporation side, and is absorbed in the evaporating sea water. This way, much of the energy (as heat) is left in the process, and is not removed with the air leaving the DewVaporation column.

Various improvements have been proposed, among those reusing the output brine and adding external heat in a stacked way, so that the pressure and humidity gap between the two sides of the column are optimal and constant.

Mating connection. A mating connection is any method of assembling of two or more component parts with mutually complementing shapes that, with some imagination, resembles the way two animals, male and female, are physically connected during the act of mating. In such connections one of the two components acts as male and the other as female, although more complex relationships exist. Any electrical connector, bolted joint, and jigsaw puzzle is an example of assembling based on mating connection.

Pencil milling. Pencil milling is a cleanup toolpath generated by computer-aided manufacturing (CAM) programs to machine internal corners and fillets with smaller radius tools to remove the remaining material  that are inaccessible with larger tools used for previous roughing, semi-finishing, and finishing toolpaths. The name comes from the way that a pencil could naturally be drawn along these corners.  It is sometimes called a rolling ball toolpath.

Often a constant step-over passes are derived from single pencil pass to create parallel pencil passes that are very good for cleaning up corners and fillets where excess material remains from a bigger cutter.

Generating pencil toolpaths 

There are several alternate algorithms for generating pencil passes.  The method most commonly published in the academic literature involves creating tool surface offsets of the model surfaces and intersecting them to find the common line where the cutter would be in contact with two surfaces at once.  An example of this implementation uses the ZMap method described by Park, et al.

Cadence SKILL. SKILL is a Lisp dialect used as a scripting language and PCell (parameterized cells) description language used in many electronic design automation (EDA) software suites by Cadence Design Systems. It was originally put forth in an Institute of Electrical and Electronics Engineers (IEEE) paper in 1990.

History
SKILL was originally based on a flavor of Lisp called Franz Lisp created at University of California, Berkeley by the students of Professor Richard J. Fateman. SKILL is not an acronym; it is a name. For trademark reasons Cadence prefers it be capitalized.

Franz Lisp and all other flavors of LISP were eventually superseded by an ANSI standard for Common Lisp. Historically, SKILL was known as IL. SKILL was a library of IL functions. The name was originally an initialism for Silicon Compiler Interface Language (SCIL), pronounced "SKIL", which then morphed into "SKILL", a plain English word that was easier for everyone to remember.

"IL" was only Interface Language. Although SKILL was used initially to describe the application programming interface (API) rather than the language, the snappier name stuck. The name IL remains a common file extension used for SKILL code  designating that the code contained in the file has lisp-2 semantics. Another possible file extension is , designating that the content has lisp-1 semantics.

Talisman UUV. The Talisman UUV is a fully autonomous unmanned mini-sub designed and made by BAE Systems. It has the capability to perform shoreline reconnaissance when the risks may be deemed too high, or conditions unsuitable, for human operators.

The Talisman system comprises a vehicle and remote control console. The vehicle can be re-programmed in mid-mission by satellite and features a carbon fibre hull giving it a stealth-like profile and low observability. Talisman can carry a wide variety of payloads, such as image capture, environmental sensors or mine counter measures.

Programme history
The Talisman programme was launched in late 2004, and was developed and managed by BAE Systems Underwater Systems and went from paper to initial trials in less than a year.

Talisman has undergone a series of trials in the Irish Sea, with 100 per cent success rate. During further trials in late 2006, Talisman has become the first UUV to successfully fire and control weapons at sea during trials off the South Coast of England.

The first remote sea launch of the Archerfish mine disposal system from Talisman was successfully completed during the trials. The mine neutraliser then acquired Talisman and subsequently simulated target eradication. In another deployment, also from the Talisman UUV, Archerfish successfully identified and acquired BAE Systems' versatile exercise mine system (VEMS).

The vehicle
The Talisman vehicle is based on an innovatively shaped carbon fibre composite hull, with internal pressure vessels containing the electronics systems and payload. The stealthy hull design was based on BAE Systems’ aircraft technology. The vehicle weighs 1800kg, is approximately 4.5m long by 2.5m wide, can dive to 300m and has a top speed of 5 knots (9 km/h).

It is fitted with vectorable thruster pods, which allow it to manoeuvre very accurately in difficult conditions, including strong currents, and over an extended period of time: the Talisman can be deployed 50 miles offshore and remain in operation for 24 hours. The precise handling in all directions comes from six thrusters, two at the front, and four at the back in two pairs. A rotary actuator is used to vector each pair of thrusters and to operate the hydroplanes.

Talisman has been designed with a software architecture, which allows easy and rapid re-configuration of the mission systems. All mission parameters are pre-settable before launch, for full autonomous operation, with the possibility of operator intervention throughout the mission.

Communications to and from the vehicle are via RF while the vehicle is surfaced and via acoustic communications systems when the vehicle is underwater.

Payloads
As standard the vehicle is equipped with a suite of environmental sensors. Other payloads are mission or role specific and can include sonar systems, mine countermeasures and even other UUVs such as Archerfish.

Ohio Valley Electric Railway. The Ohio Valley Electric Railway was a street railway and interurban system that ran between Huntington, West Virginia, and Ashland, Kentucky.  The system was also connected by ferry to Ironton, Ohio.

History

The Ohio Valley Electric Railway was incorporated in West Virginia on August 28, 1899, and, backed by Senator Johnson N. Camden, bought out the Consolidated Light and Railway Company of Huntington, the Ashland and Catlettsburg Street Railway, and the Ironton and Petersburg Street Railway. By the fall of 1900, new track connected the West Virginia and Kentucky segments of the line, and the combined properties became known as the Camden Interstate Railway Company.

In 1908, the company changed its name back to the Ohio Valley Electric Railway. Street railway operations ceased in 1937.

High-speed craft. A high-speed craft (HSC) is a high-speed water vessel for civilian use, also called a fastcraft or fast ferry. 
The first high-speed craft were often hydrofoils or hovercraft, but in the 1990s catamaran and monohull designs become more popular.
Most high-speed craft serve as passenger ferries, but the largest catamarans and monohulls also carry cars, buses, large trucks and freight.

In the 1990s there were a variety of builders, but due to HSC high fuel consumption, many shipbuilders have withdrawn from this market so the construction of the largest fast ferries, up to 127 metres, has been consolidated to two Australian companies, Austal of Perth and Incat of Hobart. There is still a wide variety of builders for smaller fast catamaran ferries between 24 and 60 metres.

Hulled designs are often powered by pump-jets coupled to medium-speed diesel engines. Hovercraft are usually powered by gas turbines or diesel engines driving propellers and impellers.

The design and safety of high-speed craft is regulated by the International Convention for the Safety of Life at Sea (SOLAS) Convention, Chapter 10, High-Speed Craft (HSC) Codes of 1994 and 2000, adopted by the Maritime Safety Committee of the International Maritime Organization (IMO).

In accordance with SOLAS Chapter 10 Reg. 1.3, high-speed craft are craft capable of a maximum speed, in metres per second (m/s), equal to or exceeding:

 

where  = volume of displacement in cubic metres corresponding to the design waterline, excluding craft of which the hull is supported clear above the water surface in non-displacement mode by aerodynamic forces generated by ground effect.
