Arado Ar 76. The Arado Ar 76 was a German aircraft of the 1930s, designed as a light fighter with a secondary role as an advanced trainer in mind.

Development
Arado's response to a requirement by the Reichsluftfahrtministerium (RLM) for a light / emergency fighter aircraft, was the Ar 76 which was evaluated against the Heinkel He 74, Focke-Wulf Fw 56, the Henschel Hs 121 and Hs 125 in 1935. Although the Fw 56 was selected for the main production contract, the RLM was sufficiently impressed by the Ar 76 to order a small number of production aircraft as well.

Design
The Ar 76 was a parasol-wing monoplane with fixed, tailwheel undercarriage. The wings were constructed of fabric-covered wood, and the fuselage was fabric-covered steel tube.

It was powered by an Argus As 10C inverted V8 which produced  and was capable of propelling the Ar 76 up to a maximum speed of  and to a maximum altitude of .

When used as a fighter the Ar 76 was armed with twin 7.92mm MG 17 machine guns which were mounted above the engine and each had access to 250 rounds. However, when used as an advanced trainer, it only carried a single MG 17. Alongside this it could also carry two  SC 10 bombs, one under each wing.

Operational history
Production Ar 76A aircraft were used by Jagdfliegerschulen (fighter pilot schools) from 1936.

Neutron supermirror. A neutron supermirror is a highly polished, layered material used to reflect neutron beams. Supermirrors are a special case of multi-layer neutron reflectors with varying layer thicknesses.

The first neutron supermirror concept was proposed by Ferenc Mezei, inspired by earlier work with X-rays.

Supermirrors are produced by depositing alternating layers of strongly contrasting substances, such as nickel and titanium, on a smooth substrate.  A single layer of high refractive index material (e.g. nickel) exhibits total external reflection at small grazing angles up to a critical angle .  For nickel with natural isotopic abundances,  in degrees is approximately  where  is the neutron wavelength in Angstrom units.

A mirror with a larger effective critical angle can be made by exploiting diffraction (with non-zero losses) that occurs from stacked multilayers.  The critical angle of total reflection, in degrees, becomes approximately , where  is the "m-value" relative to natural nickel.   values in the range of 1–3 are common, in specific areas for high-divergence (e.g. using focussing optics near the source, choppers, or experimental areas) m=6 is readily available.

Nickel has a positive scattering cross section, and titanium has a negative scattering cross section, and in both elements the absorption cross section is small, which makes Ni-Ti the most efficient technology with neutrons.  The number of Ni-Ti layers needed increases rapidly as , with  in the range 2–4, which affects the cost.  This has a strong bearing on the economic strategy of neutron instrument design.]

ISO 15926 WIP. The ISO 15926 is an interoperability standard in the process industry. ISO 15926 includes the Work in Progress (WIP) database. WIP is available online and includes technical class descriptions of all the main equipment items, pipe, instruments, buildings, activities and anything else used in engineering, constructing, procuring, operating and maintaining process facilities.

Description 

The ISO 15926 Reference Data Library contains the approved core library set and the Object Information Models (e.g. product models), but is expanded with proposed classes and proposed model extensions.

Work process 
To expand the set, a user must be certified. This is to keep the Reference Data Library in a certain structure, and directly usable for all the various connected projects.

When a new item is submitted by a certified user, it can be used immediately, and it will also enter an approval cycle performed by modeling and domain matter experts. In this cycle the new item can reach a higher status of approval; up until ISO certification.

History 
In order to create the WIP, the builders needed to have the content, the infrastructure and the tools.

 The content was created originally by many companies, starting around 1992. At some point it was divided up into Reference Data Libraries called STEPlib (of USPI) and PClib (of POSC Caesar Association). In 2005-2006, these libraries were merged again into the present content. About 10,000 classes are now (2007) ISO certified. That set is called the core library. In the near future the content will be expanded by the POSC Caesar IDS project, with new classes and with Object Information Models.
 The infrastructure is created by the POSC Caesar Association RDS (Reference Data System) project. It consists of Express-native and SQL Server databases which can be opened through multiple web-enabled screens. Some screens are targeted for engineers and some for modelers. In 2007 and 2008 it will be in operation with 24/7 access. This infrastructure will be kept as a test to gain experience with the procedures and operations. In the future ISO Maintenance Agency will take over the content and it may be brought into a different infrastructure, using the gained experience.
 The tools are created by the POSC Caesar RDS project and the FIATECH ADI project.

Engine Arm Aqueduct. The Engine Arm Aqueduct near Smethwick, West Midlands, England, was built in 1825 by Thomas Telford to carry a water feeder, the Engine Arm, from Edgbaston Reservoir over the BCN New Main Line canal to the adjacent and parallel Old Main Line. The structure is maintained by the Canal & River Trust. It is a Scheduled Ancient Monument and is Grade II* listed.

The bridge is a 52ft (16m) span cast iron arch structure formed by 5 ribs, each of them consisting of four sections with bolted joints. The ribs are connected to each other by transverse members and they are fixed to the masonry abutments. The three central ribs support the 8ft wide (2.4m) cast iron trough and the outer ones support the 4ft-4in (1.32m) towpaths and the bracing that connects to the sides of the trough. The towpath support consists of an arcade of Gothic arches with quatrefoil spandrels. The eastern towpath is paved in brick with raised strips for horses. The ironwork was cast at the Horseley Ironworks at Tipton, which is where most of Thomas Telford bridges were cast.

Configurable Fault Tolerant Processor. The Configurable Fault Tolerant Processor (CFTP), developed by the Space Systems Academic Group at the Naval Postgraduate School, is an experimental payload on board the United States Naval Academy's (USNA) MidSTAR-1 satellite.  Midstar-1 was launched into a 492km low Earth orbit (LEO) on March 8, 2007, aboard an Atlas V expendable launch vehicle from Cape Canaveral Air Force Station, along with FalconSat 3, STPSat 1, and CFESat as secondary payloads. The primary payload was Orbital Express.

CFTP Purpose

The Configurable Fault Tolerant Processor Project aims to demonstrate the feasibility of using Field Programmable Gate Arrays (FPGAs) for spacecraft computer processing by applying various fault tolerance techniques to the designs.  CFTP provides a valuable testbed for on-orbit evaluation of various fault tolerant concepts.

The use of FPGAs provides added flexibility, allowing on-orbit upgrades and rapid development cycles.  Using Commercial off the shelf (COTS) technology allows the engineer to produce more technologically advanced designs at a lower cost and in a shorter time than using more traditional space-grade components.  

Space-based FPGA design also provides the Naval Postgraduate School students with unique challenges in developing for and configuring the system. Remotely accessing the platform over a limited downlink and uplink provides challenges not seen on ground-based systems.

CFTP Versions

CFTP-1

The CFTP-1 board utilizes Xilinx Virtex I parts for both the control and experiment FPGAs.  The complete CFTP payload, as delivered to MidSTAR-1, consists of the CFTP board itself (shown in the spacecraft image above), an ARM processor board that communicates with the control FPGA on the CFTP board through a PC/104 bus, and a power supply board.  The ARM processor board communicates with the spacecraft's Command and Data Handler (C&DH) computer through a serial PPP link.

CFTP-1 underwent radiation testing at the UC Davis' cyclotron facility prior to integration with the MidSTAR satellite.

CFTP-2

The CFTP-2 system is currently an entirely ground based system.  The CFTP-2 board itself is set up nearly identically to the CFTP-1 board, however it utilizes a Xilinx Virtex 2 part as the experiment FPGA, rather than the Xilinx Virtex I part on CFTP-1.  This system was tested in a proton beam using the University of California at Davis' cyclotron.

Al-Mogran Development Project. The Al-Mogran Development Project is an over $4 billion development project undertaken by the Alsunut Development Company that seeks to develop several thousand acres in downtown Khartoum along the spot where the White Nile and Blue Nile merge to form the Nile. The discovery of oil in Sudan has provided the Sudanese government with a billion dollar surplus that allows the funding of this project.

Starting in 2004, the project has two main phases:

 Phase I: The Central Business District development
 Phase II: The residential estate portion

The Al-Mogran project, when completed, would have produce  of office space, 1,100 villas, housing for 45,000 residents and visitors, and jobs for 60,000 Sudanese. The project, however, has received criticism in light of the continuing Darfur Conflict. Completion was expected by 2014.

Disruption 
With the Sudanese government facing increased pressure to halt the conflict in Darfur, the Al-Mogran project came to a halt in 2007 after the United States included the project management company, Al Sunut Development to the OFAC Sudan sanctions list, due to its connection to the Sudanese government.

Recent 

In 2021, the Emirates Stallions Group announced a hospitality project within the Al Mogran Development in partnership with DAL Group worth $65.3 million. The project will consist of a 16-floor hotel and residences.

Application Session Controller. In computer networking, the Application Session Controller (ASC) network element resides at the application layer and sits between the application layer and the core network to provide and manage connectivity to the evolving telecom network. The ASC incorporates a number of open standard APIs, plus the signaling, media between disparate networks that converged.  It insulates the application server farm from the network below via a programmable network abstraction engine, thereby providing the application specific call-control functions independent of each network.

The ASC incorporates a number of open standard APIs, plus the signaling, media, and the feature inter-working between disparate networks that converged and consolidated applications require. It is scalable to support tens of millions of subscribers via a single system or via clustering and provides the necessary calls per second / transactions per second required for large-scale multi-network environments.

As Communications Service Providers continue to deploy new network assets and technology at an increasingly rapid pace, achieving feature transparency becomes very challenging. The benefit of creating a solution to ensure feature transparency will provide subscribers application feature parity across multiple networks, enable the service providers to consolidate their application platforms and fully enable them to leverage their network assets to offer converged applications across ever evolving networks.
