PathEngine. PathEngine is a software company as well as an advanced path finding software development kit, created under the leadership of Thomas Young. The company was founded after Young left Infogrames Sheffield, and the first commercial version of the software was offered in 2002. The software uses a technique called points of visibility path finding, where the agent takes into account dynamic obstacles and agent shape when navigating between points. Over time, the software has been optimized with rapid bug-fixes, and has been made to support platforms such as the Xbox 360. PathEngine has been used in games such as Titan Quest, among others.

History 
PathEngine was founded in 2000. The first version of PathEngine SDK was released in early 2002. By the end of 2005, over 50 finished products had been released that used PathEngine.

In 2007, the 5.10 version was released. Improvements included a new graph search core and several bugfixes. In 2010, PathEngine released version 5.23.

Features 
PathEngine supports personal computers running the Microsoft Windows, Linux and FreeBSD, as well as the game consoles of Xbox 360 and PlayStation 3.

PathEngine implements the search for the path and the movement of the agent in a three-dimensional medium with dynamic obstacles. There is a dynamic control overcoming obstacles and automation of content. Such a technology applied to some very large and detailed worlds includes special optimization for embossed surfaces (or other surfaces that combine detailed obstacles with a good overview and large open spaces).

License terms 
PathEngine is a commercial software product created solely for the purpose of being licensed by third parties. There are three types of licenses for PathEngine SDK, each of which differs in price and level of access to the source code. In addition, each license may differ depending on which and how many platforms the final product will be released on.

Paul Wallace (racing driver). Paul Wallace (born 22 October 1958) is a British former racing driver.

Early life

Born on 22 October 1958 to Ruth and Kenneth Wallace, Paul Wallace was educated at The King's School, Grantham. He then studied Mechanical Engineering at UMIST.

Following his degree, Wallace worked for three large corporates: RHP Bearings, Fisons Pharmaceuticals and Mars Electronics. In 1987 he went into business, setting up his own successful software company, PWA, which developed and marketed a range of leading HR/Personnel software applications with many blue chip clients in the UK and worldwide. His company was sold to Great Plains Software (which became a division of Microsoft) in 2000. Following this sale, Paul decided to pursue his long term wish to compete professionally in motorsports.

Racing career

Starting in 1998, Wallace competed in the Tomcat Vento Challenge. In 2000 Wallace won the Tomcat Championship title driving a Rover 220 Coupe Turbo. He entered his Rover into the Super Coupe Cup for the 2001 season. After leaving the Super Coupe Cup, Wallace began driving in the Elf Clio Renaultsport UK Cup. He completed two winter championships (2001 and 2002) and the full 2002 season, finishing 19th. In 2003 he began his British Touring Car Championship career.

The first half of the season was spent in the Production Class, with an Alfa Romeo 156 during which he achieved 3 top three finishes. For the second half of the year he moved into the Touring Class, replacing Gavin Pyper in a Vauxhall Astra Coupé. Both cars were run by former racer Gary Ayles and his team, GA Motorsport. Wallace returned for the 2004 BTCC season under the 'Team Sureterm' banner. After round six he was replaced in the team by Kelvin Burt.

He went on to compete in the MG Trophy from 2005, winning the trophy in 2006 and placed in the top 3 in all other seasons. He set four lap records in his final season (2008). He finished motor racing after the 2008 season, to pursue other business activities.

He is now retired and lives in Switzerland.

PSU Zephyrus. The PSU Zephyrus is a human-powered aircraft being constructed by the Penn State AERSP 404H team. It is a composite material, single-seat, single propeller, high-wing airplane. The Zephyrus is designed to compete in the Kremer prize sport competition.

Development
The PSU Zephyrus was developed to compete in the Kremer's prize sport competition. The basic mission goal is to traverse an equilateral triangle with sides of 500 meters once in each direction in seven minutes. The competition specifies a minimum average airspeed of 5.0 m/s during the flight. In addition, for a flight to be considered official, the airspeed cannot drop below 5.0 m/s for a period of more than 20 seconds.
The aircraft is also being developed and constructed as a fulfillment of the course requirements of Penn State's AERSP 404H course.

Design

Fuselage
The fuselage was sized based a dimension range of a 5’10”(1.78 m) pilot and the assumption that the pilot could output the necessary power-to-weight ratio to fly the aircraft will be no greater than 1.78 m. Constraints include minimum widths for pilot comfort and desired center of gravity of the aircraft. The shape of the pod was designed to be a low-drag body that will not generate lift regardless of angle of attack. The length of the shape was reduced to allow for aircraft maneuverability in crosswind. The internal structural members are designed to firmly hold the seat configuration in place, yet still provide a maximum field of vision for the pilot. Structural members attach to the main boom at a hard-point located behind the trailing edge of the wing.

Propeller
To successfully complete the challenge, it was determined that the propeller would need to produce 27.5 N of thrust when cruising at 11.5 m/s and spinning at 135 rpm. To meet these requirements, the propeller design underwent many alterations, with the final design broken into two components.

Wing
Starting from a parent aircraft approach, primarily using the Musculair 1 and 2, but also including the Monarch B, MIT Daedalus, and Velair models, a first iteration choice for an airfoil was made. A modified version of the FX-76MP, as used for the Musculair 2 was chosen. Taking characteristics from this airfoil, using an initial weight buildup, the wing planform size was determined. Then, assuming a take-off weight of 81 kg (27 kg empty weight), sea-level air density, and using a CL at cruise of 0.8.

Control Surfaces
Ailerons were designed as a piano hinge attached near the upper surface, so the upper surface incorporates the leading edge radius, so that the upper surface maintains smooth flow. This design maximizes weight efficiency and construction ease.

Philadelphia Bourse. 

The Philadelphia Bourse was a commodities exchange founded in 1891 by George E. Bartol, a grain and commodities exporter, who modeled it after the Bourse in Hamburg, Germany. The steel-framed building – one of the first to be constructed – was built from 1893 to 1895, and was designed by G. W. & W. D. Hewitt in the Beaux-Arts style.  Carlisle redstone, Pompeian buff brick and terra cotta were all used in the facade.  The building was sold in 1979 to Kaiserman Company and underwent extensive renovations, bringing the internal usable surface to approximately 286,000 square feet (26,000 square meters). In 2016, MRP Realty took ownership of the building and spent $40 million renovating it. MRP Realty owns the building as part of a three-building collection named The Independence Portfolio, which also includes 325 Chestnut and 400 Market Street—both located within a block of The Bourse. The building is home to nine floors of office space which includes the Mexican Consulate in Philadelphia. There is also a food hall on the first floor which opened on 15 November 2018.

History

Upon his return from a European trip in 1890, Bartol organized the Philadelphia business community. He asked each new member to pledge $1,000 to the project. The Bourse motto was "Buy, Sell, Ship via Philadelphia."

The Bourse stopped functioning as a commodities exchange in the 1960s. The structure continued to serve as an office building until 1979, when it was sold and renovated to include upscale retail space on floors near the street level. The upper levels of the building continued to house office space.  A movie theater specializing in independent films, The Ritz at the Bourse, sits across the street at 4th and Ranstead streets.

In 2018, a two-year rehabilitation created a brand new food hall with 30 vendors.

The building is listed on the National Register of Historic Places.

Today 

After a two-year rehabilitation, The Bourse reopened as a modern food hall with 30 vendors in November, 2018.  However, the covid pandemic severely impacted these businesses and as of June 2024 all the restaurants are closed and abandoned.  It has been reported a new developer is acquiring the building to turn it into a wedding venue.

Minato Bridge. The Minato Bridge is a double-deck cantilever truss bridge in Osaka, Japan; upper deck is for Hanshin Expressway Route 16 Osakako Line, and lower deck is Route 5 Bayshore Line.  It opened in 1974.  It is the third-longest cantilever truss span in the world, behind the Quebec Bridge and the Forth Bridge.

Designs including arch and suspension elements were eliminated from consideration due to poor subsoil conditions of alternating layers of clay and gravel.  Instead, the designers selected a cantilever structure using high-strength steel, to reduce mass.

Austin transformer. An Austin ring transformer is a special type of isolation transformer with low capacitance between the primary and secondary windings and high isolation.

Etymology
It is named after its inventor, Arthur O. Austin.

Background
AM radio stations that broadcast in the medium frequency (MF) and low frequency (LF) bands typically use a type of antenna called a base-fed mast radiator.  This is a tall radio mast in which the steel mast structure itself is energized and serves as the antenna.  The mast is mounted on a ceramic insulator to isolate it from the ground and the feedline from the transmitter is bolted to it.  Typically the mast will have a radio frequency AC potential of several thousand volts on it with respect to ground during operation. 

Aviation regulations require that radio towers have aircraft warning lights along their length, so the tower will be visible to aircraft at night.  The high voltage on the tower poses a problem with powering the lights.  The power cable that runs down the tower and connects to the utility line is at the high voltage of the mast.  Without protective equipment the RF current from the mast would flow down the cable to the power line ground, short-circuiting the mast.  To prevent this, a protective isolator device is installed in the lighting power cable at the base of the mast which blocks the radio frequency power while allowing the 50/60 hertz AC mains power for the lights through.

Use and mechanism
The Austin transformer is a specialized type of isolation transformer made specifically for this use, in which the primary and secondary windings of the transformer are separated by an air gap, wide enough so the high voltage on the antenna cannot jump across.  It consists of a ring-shaped toroidal iron core with the primary winding wrapped around it, mounted on a bracket from the mast's concrete base, connected to the lighting power source.  The secondary winding which provides power to the mast lights is a ring-shaped coil which circles the toroidal core through the center, like two links in a chain, with an air gap between the two. The magnetic field created by the primary winding induces current in the secondary winding without the necessity of a direct connection between them.  The wide gap of several centimeters between the coils also ensures that there is minimal interwinding capacitance, to prevent RF voltage being induced in the supply wiring by capacitive coupling. A spark gap is often located nearby with a gap smaller than the gap between the rings, to prevent damage to the transformer and transmitting equipment in the case of a lightning strike.
