Cadet UT-1. The Cadet UT-1 is an American single-seat, high wing, strut-braced glider modified by Alex Dawydoff from the original Slingsby Kirby Cadet design and produced by Cadet Aeronautics.

Design and development
In 1942 Dawydoff obtained the plans and the rights to produce the Slingsby Cadet under licence from Fred Slingsby. Dawydoff had the plans redrawn to US measurements, the structural strength increased, plus a new tow hook and wing rigging design. The wing is assembled using just one  long pin per wing.

The UT-1 is built predominantly from wood, with the fuselage wooden framed and covered in plywood. The wing and tail are also wooden-framed and covered in doped aircraft fabric covering. The two-spar wing is supported by dual struts.

Dawydoff's plan was to gain government support to provide the UT-1 in kit form for assembly by schools and clubs. The government money was not forthcoming and the post-war period saw a large number of surplus military training gliders saturate the market. As a result, only one UT-1 was completed. It is now located in the National Soaring Museum.

Passage development (Egypt). Path of Development and Reconstruction (Egypt) to enhance the economy of Egypt, is a national project in the Western Desert of Egypt that is proposed by Farouk El-Baz initially in the 80th and reintroduced to the Egyptian government after the 25 January, 2011 revolution.

Description 

The passage development is a corridor reconstruction route that starts on the Mediterranean coast at the site between Alexandria and El Alamein. It includes the establishment of a new global port comparable to other international ports, and provides for the use of modern information technology in dealing easily and quickly with exports and imports of goods and commerce.

Development consists of the main road of the eight lanes at least, two of the trucks and two cars back and forth, as necessary, paved to international standards that allow safe speed without stopping, except in cases of emergency stations and rest, fuel centers and collection of fees for traffic.

Water pipe

Necessary to provide safe drinking water along the corridor of the proposed plateau of Western Sahara.

Power line

Necessary for the proposal to establish a line of electricity for lighting and cooling along the main road, especially because the route passes in a desert area where the requirements do not exist Development infrastructure, through the early stages of the project.

Asger Ostenfeld. Asger Skovgaard Ostenfeld (13 October 1866 – 23 September 1931) was a Danish civil engineer who specialized in the theory of steel and reinforced concrete structures. He is now considered to be the founding father of the theory of structures in Denmark.

Biography

Ostenfeld was born in Hvirring near Horsens in Jutland in 1866. From 1900, he was professor of applied mechanics and steel structures at the Technical University of Denmark. In 1894, he designed the Langelinie Bridge at Østerport Station which at the time was the largest structure in Denmark built by a Danish engineer. In 1926, he was instrumental in creating Denmark's first Theory of Structures Laboratory which he later directed. Ostenfeld published a number of textbooks on the theory of structure which were widely read outside Denmark.

Deformation method

Around 1920, Ostenfeld extended Axel Bendixsen's method of deformations together with the force method creating the dual concept of the method of deformations. His method represented significant progress in that "it enables previously analysed structural elements so to speak, to be built on". This is achieved through the introduction of rigidly fixed members for the obstruction of joint rotations. It allows the complete frame to be divided into finite elements.

Trilogic Expert Cartridge. The Expert Cartridge from the UK company Trilogic was a popular extension cartridge which was introduced in mid-1986 for the Commodore 64 and a later Commodore 128 compatible version, It offered a fast loader, increasing the speeds of the disk drive, and a freezer, allowing the program execution to be stopped to be resumed later. Later Cat & Korsh International took over the distribution and the Trilogic name disappeared from the cartridge.

A major difference to the other two The Final Cartridge III and Action Replay is that it held its system software in an 8 kB RAM that could be reprogrammed. And thus allowed the user to change its functionality.

The author of the Expert Cartridge default firmware is John Twiddy who also programmed The Last Ninja for the Commodore 64. He claims that it saved him many months of programming.

ISEPIC. The ISEPIC ("Ice-pick") from Starpoint Software in USA is an extension cartridge introduced in June 1985 for the Commodore 64. It offers the capability to memory dump software regardless of the implementation scheme or storage medium. The resulting snapshot can be tested before saving.

Snapshots require ISEPIC to run, but can be modified to create standalone versions that do not need the cartridge. A major factor is the 2 KB RAM that can be reprogrammed, and thus allows the user to change its functionality. The 2 KB RAM is memory banked into a 256-byte page at  – .

Reception
ISEPIC creator Chip Gracey said that he sold 20,000 cartridges within one year, mostly through computer clubs and magazines.

Ahoy! in October 1985 stated that "the ramifications of [ISEPIC] are startling, to say the least". While warning readers against violating copyright, the magazine discussed the cartridge's ability to both produce snapshots that require the cartridge to boot, and help users modify snapshots to produce standalone versions of programs ("In the tradition of the true hacker, these routines also display the Isepic logo while booting the program"). In a review of two other memory dumpers ("Clonebuster" and "Capture") in March 1986, the magazine stated that they were superior: "While ISEPIC did not do bad as a forerunner, it does not measure up to the products reviewed here" which, among other improvements, produce standalone snapshots.

Robert Thom (engineer). Robert Thom (1774 Tarbolton, South Ayrshire, Scotland - 1847) was a Scottish civil engineer who worked upon major hydraulic projects on the Isle of Bute and Inverclyde.  On Bute, he created aqueducts to increase the flow of water which powered the cotton mills there, so that their capacity was increased.  This economic success resulted in him becoming the laird of Ascog.  He then created a larger system to supply water power to Greenock. The reservoir is named after him — Loch Thom — and the supply aqueduct is known as the Greenock Cut. In the early 1800s, he designed the first water purification plant in Scotland.

Daebul Industrial Complex. Daebul Industrial Complex () is an industrial complex which covers a large portion of Samho, Yeongam of South Jeolla province in South Korea. The complex was initially designed to set up fundamental base for development in the Mokpo area. Finalized in December 1996, the residence of enterprises start from 1997. The complex was initially aimed at the south east Asia and China market.

Disposals of the site plots had been quite difficult since its launch to start lease for foreigners since 2000 to rearrange supplies of LNG and infrastructure. Until 2001, portion of parcel stayed at 30% to confront serious complains by regional municipalities. 

The establishment of Hyundai Samho Heavy Industries following purchase from Halla group greatly promoted the economical encouragement in local area, attracting businesses in similar or related industries. The connection from Seohaean expressway also increased the easier approach from Seoul via cars and also railroad via Mugunghwa-ho. The province also started advertisement to gain public gains through investment.

The region went through disadvantage via industrialization of South Korea, while shipbuilding industries has technically promoted further investment to boast local regional economy including Mokpo and south western coastal area. To settle down functional difficulties for foreign investors, the provincial office tackled down inquired matters from social infrastructure including expressway, gases, fundamental traffic map to license permissions.

In 2002, Ministry of Industries designated the Daebul area as a free trade region to attain additional support in national level to raise up the inter-related industries like shipbuilding and renewable energy provision. In Honam area, Daebul is supposed to co-operate that resided in Gunsan, Iksan and Gwangju. 

Mokpo Customs also resides in this complex to inspect imported merchandise.

TIBCO Hawk. TIBCO Hawk is a software product that allows monitoring and management of distributed computing applications. A very scalable product, it is notable for the number of these rule-based software agents deployed (organisations and in total) claimed by the vendor:

Details
TIBCO Hawk provides a distributed agent-based extensible system which allows the monitoring and control of system and application software components. There are 3 main components: 
 Hawk Agents, which embed MicroAgents that in turn communicate with application  and system services and processes, or external interfaces
 Hawk Display, which provides a user interface displaying the community of agents (and thereby systems)
 Hawk Event Service, which provides the ability to store and retrieve events via a database.

Hawk Agents include a non-inferencing, event-driven rule engine to filter events and send alerts to Hawk Display(s). The rulebases for these can be updated and distributed from a Hawk Display while the agents are operating.

Hawk is designed to be customisable to suit specific enterprise requirements. For example, custom MicroAgents can be used to monitor custom applications though an Application Monitoring Interface (API) using C, C++, or Java. These allow for dynamic discovery on startup, application heartbeat testing, and so on.

Hawk Microagents and adapters are either included or available as options: they either turn system information or events into Hawk events, or turn Hawk events into system actions. These include:
 Process MicroAgent: allows processes to be monitored (e.g. number of processes and resources used)
 Filesystem MicroAgent: allows file systems to be monitored (e.g. space available)
 System microagent: system resources to be monitored (e.g. CPU and memory utilization)
 Logfile MicroAgent: allows system logs to be read
 Custom MicroAgent: allows scripts to be executed on a system and return some values
 Database MicroAgent: monitor the system tables of database engines via JDBC
 JVM MicroAgent: monitors JVM resources (e.g. memory and thread information)
 JMX MicroAgent: monitors JMX information
 SNMP MicroAgent: communicates with SNMP services

Chase-Sisley C100-S. The Chase-Sisley C100-S is an American mid-wing, single seat FAI Open Class glider that was designed in the 1960s by Dr. Robert Chase.

Design and development
The C100-S project was started by Chase in 1962, with prototype construction commenced near the end of 1963. The resulting aircraft was first flown in 1968.

The aircraft is built from a combination of wood, styrofoam, aluminium and fiberglass. The semi-tapered wing is built from wood and styrofoam, covered with stress-bearing fiberglass. The wing is tapered outboard of the mid-span point. The wing spar is built up from 14 layers of fiberglass and epoxy resin at the root and is a box-style spar that occupies 40% of the wing chord. The wing is constructed in three pieces, a center-section and wing tips and features Schempp-Hirth dive brakes. The wing is 15% thick and employs a NACA 64(3)-615 laminar flow airfoil.

The fuselage is built from aluminium and features stressed skin construction. The landing gear is a fixed monowheel. The pilot's seating position is semi-reclined. In addition to the dive brakes the pilot has a tail-mounted drag chute available.

Only one C100-S was ever built and it is registered in the experimental amateur-built category.

Operational history
The former owner of the glider, Dr. Richard Sisley of Los Angeles, California, reported in 1983 that the aircraft had excellent thermalling flight characteristics.

In May 2011 the sole example produced was still registered with the Federal Aviation Administration.

Berlekamp–Welch algorithm. The Berlekamp–Welch algorithm, also known as the Welch–Berlekamp algorithm, is named for Elwyn R. Berlekamp and Lloyd R. Welch. This is a decoder algorithm that efficiently corrects errors in Reed–Solomon codes for an RS(n, k), code based on the Reed Solomon original view where a message  is used as coefficients of a polynomial  or used with Lagrange interpolation to generate the polynomial  of degree < k for inputs  and then  is applied to  to create an encoded codeword .

The goal of the decoder is to recover the original encoding polynomial , using the known inputs  and received codeword  with possible errors. It also computes an error polynomial  where  corresponding to errors in the received codeword.

The key equations 

Defining e = number of errors, the key set of n equations is

Where E(ai) = 0 for the e cases when bi ≠ F(ai), and E(ai) ≠ 0 for the n - e non error cases where bi = F(ai) . These equations can't be solved directly, but by defining Q() as the product of E() and F():

and adding the constraint that the most significant coefficient of E(ai) = ee = 1, the result will lead to a set of equations that can be solved with linear algebra.

where q = n - e - 1. Since ee is constrained to be 1, the equations become:

resulting in a set of equations which can be solved using linear algebra, with time complexity .

The algorithm begins assuming the maximum number of errors e = ⌊(n-k)/2⌋. If the equations can not be solved (due to redundancy), e is reduced by 1 and the process repeated, until the equations can be solved or e is reduced to 0, indicating no errors. If Q()/E() has remainder = 0, then F() = Q()/E() and the code word values F(ai) are calculated for the locations where E(ai) = 0 to recover the original code word. If the remainder ≠ 0, then an uncorrectable error has been detected.

Example

Consider RS(7,3) (n = 7, k = 3) defined in  with α = 3 and input values: ai = i-1 : {0,1,2,3,4,5,6}. The message to be systematically encoded is {1,6,3}. Using Lagrange interpolation, F(ai) = 3 x2 + 2 x + 1, and applying F(ai) for a4 = 3 to a7 = 6, results in the code word {1,6,3,6,1,2,2}. Assume errors occur at c2 and c5 resulting in the received code word {1,5,3,6,3,2,2}. Start off with e = 2 and solve the linear equations:

Starting from the bottom of the right matrix, and the constraint e2 = 1:

 with remainder = 0.

E(ai) = 0 at a2 = 1 and a5 = 4
Calculate F(a2 = 1) = 6 and F(a5 = 4) = 1 to produce corrected code word {1,6,3,6,1,2,2}.
