Generic Modeling Environment. The Generic Modeling Environment (GME) is a domain-specific, model-integrated program synthesis tool for creating domain-specific models of large-scale systems. GME development started in 2000 at Vanderbilt University, US and continues well into 2022. Initially it only supported MS Windows OS, but later evolved into WebGME, a web- and Node.js- based software. Its primary purpose is model-building.

Overview 
GME allows users to define new modeling languages using UML-based metamodels. GME was developed in 2000 by the Institute for Software Integrated Systems at Vanderbilt University. GME is a part of the META Tool Suite and the Adaptive Vehicle Make program. The main language it uses is CyPhyML.

DISCUS. DISCUS, or distributed source coding using syndromes, is a method for distributed source coding. It is a compression algorithm used to compress correlated data sources.  The method is designed to achieve the Slepian–Wolf bound by using channel codes.

History

DISCUS was invented by researchers S. S.  Pradhan and K. Ramachandran, and first published in their
paper "Distributed source coding using syndromes (DISCUS): design and construction",
published in the  IEEE Transactions on Information Theory in 2003.

Variations
Many variations of DISCUS are presented in related literature. One such popular scheme is the Channel Code Partitioning scheme, which is an a-priori scheme, to reach the Slepian–Wolf bound. Many papers illustrate simulations and experiments on channel code partitioning using the turbo codes, Hamming codes and irregular repeat-accumulate codes.

Flow stress. In materials science the flow stress, typically denoted as Yf (or ), is defined as the instantaneous value of stress required to continue plastically deforming a material - to keep it flowing. It is most commonly, though not exclusively, used in reference to metals. On a stress-strain curve, the flow stress can be found anywhere within the plastic regime; more explicitly, a flow stress can be found for any value of strain between and including yield point () and excluding fracture ():  .

The flow stress changes as deformation proceeds and usually increases as strain accumulates due to work hardening, although the flow stress could decrease due to any recovery process. In continuum mechanics, the flow stress for a given material will vary with changes in temperature, , strain, , and strain-rate, ; therefore it can be written as some function of those properties:

The exact equation to represent flow stress depends on the particular material and plasticity model being used. Hollomon's equation is commonly used to represent the behavior seen in a stress-strain plot during work hardening:

Where 
 is flow stress, 
 is a strength coefficient, 
 is the plastic strain, and 
 is the strain hardening exponent. Note that this is an empirical relation and does not model the relation at other temperatures or strain-rates (though the behavior may be similar).

Generally, raising the temperature of an alloy above 0.5 Tm results in the plastic deformation mechanisms being controlled by strain-rate sensitivity, whereas at room temperature metals are generally strain-dependent. Other models may also include the effects of strain gradients. Independent of test conditions, the flow stress is also affected by: chemical composition, purity, crystal structure, phase constitution, microstructure, grain size, and prior strain.

The flow stress is an important parameter in the fatigue failure of ductile materials.  Fatigue failure is caused by crack propagation in materials under a varying load, typically a cyclically varying load.  The rate of crack propagation is inversely proportional to the flow stress of the material.

Mass Storage Control Protocol. The Mass Storage Control Protocol (MSCP) is a protocol that was designed by Digital Equipment Corporation of Maynard, Massachusetts for the purposes of controlling their high-end mass storage options.

First implemented in the HSC50 hierarchical storage controller, the protocol quickly spread throughout the entire line of mass storage controllers built by DEC. The UDA50 is an implementation of MSCP built on a Unibus card; other implementations (for example, the RQDX) stretch down to the Q-bus and small, 5 megabyte disk drives and even diskettes.

Designed to minimize the amount of CPU involvement, the protocol depends upon two queues. Into one queue are placed packets which fully describe the commands to be executed by the mass storage subsystem. To initiate an I/O request, the CPU has only to create a small data structure in memory, append it to a "send" queue, and if that is the first packet in the send queue, wake the MSCP controller. After the command has been executed, an appropriate status packet is placed into the second queue to be read by the CPU.

Interrupts to the CPU (a costly operation) are not needed so long as further command packets remain in the command queue and the response queue is not in danger of over-flowing. I/O-space reads and writes to the MSCP controller, a less-expensive but still-costly operation, are similarly minimized.

Because MSCP packets were deliberately designed to resemble the packets exchanged on the VMScluster interconnects, it is a very inexpensive operation to ship storage requests around a VMScluster for remote execution; this greatly facilitates the creation of large-scale VMSclusters. The dependence upon in-memory packets and the minimization of interrupts and I/O-space reads and writes greatly facilitates remote operations.

Source Code in Database. Source Code in Database (SCID) is a technique of code manipulation where the code is parsed and stored in a database. This allows many productivity-enhancing shortcuts which were otherwise not possible.

A drawback of SCID systems is that code with syntax errors or other code that cannot be parsed, cannot be imported into a SCID system directly.  One workaround for this is to comment out code that doesn't parse correctly.

Visual programming tools may store programs as databases, since specialized structure editors are required to edit visual code.

Examples

IBM VisualAge Java is an example of an integrated development environment implementing SCID features. A more recent example of Source Code in Database is CodeOntology, an open source tool and RDF database of Java source code that supports advanced SPARQL queries, such as Select recursive methods or Select methods that compute the cube root of a double.

Apple Assembly Line. Apple Assembly Line was a monthly newsletter edited by Bob Sander-Cederlof from October 1980 through May 1988. The publisher was S-C Software Corporation based in Dallas, Texas.

Overview
The newsletter focused on assembly language programming for the Apple II personal computer. Initially, the programs were only written for the MOS 6502 microprocessor, but this expanded to the 65C02, 65802, and 65816 microprocessors as the Apple II family continued to develop.

Sander-Cederlof used the S-C Macro Assembler, which he had authored and sold himself, to publish his programs. At its peak, the newsletter had over 1000 subscribers–mainly those learning to program in assembly language–with issues being mailed all over the world.

In a retrospective of Apple II periodicals, Steven Weyhrich wrote:

HMS Rye (J76). HMS Rye (J76) was a  built for the Royal Navy during the Second World War.

Design and description
The Bangor class was designed as a small minesweeper that could be easily built in large numbers by civilian shipyards; as steam turbines were difficult to manufacture, the ships were designed to accept a wide variety of engines. Rye displaced  at standard load and  at deep load. The ship had an overall length of , a beam of  and a draught of . The ship's complement consisted of 60 officers and ratings.

She was powered by two Parsons geared steam turbines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of  and gave a maximum speed of . Rye carried a maximum of  of fuel oil that gave her a range of  at .

The turbine-powered Bangors were armed with a 12-pounder  anti-aircraft gun and a single QF 2-pounder (4 cm) AA gun. In some ships the 2-pounder was replaced a single or twin  20 mm Oerlikon AA gun, while most ships were fitted with four additional single Oerlikon mounts over the course of the war. For escort work, her minesweeping gear could be exchanged for around 40 depth charges.

Construction and career
Rye was built by the Ailsa Shipbuilding Co. Ltd. in Troon, Scotland and commissioned in 1941. Her pennant number was J 76. Rye served in the Mediterranean Sea based in Malta as part of the 14th/17th Minesweeper Flotilla. She took part in the Malta Convoys, notably Operation Harpoon during which she rescued 84 survivors from the SS Chant, and in Operation Pedestal during which she was one of the ships that rescued the SS Ohio. The Ryes captain, Iain Pearson, was awarded a bar to his DSC for service during the Malta Convoys.

After the Mediterranean, Rye returned to Home waters and served with the 14th M/S Flotilla based in Plymouth. She was part of Operation Neptune, the naval component of Operation Overlord (D-Day). The flotilla participated in minesweeping operations from 5–30 June, initially clearing paths through the German minefields to the invasion beaches, and subsequently clearing wider areas to allow transport and supply vessels to operate in safety.

Postwar 
Rye was decommissioned on 24 August 1948. She was scrapped at Purfleet in Essex in September 1948. Her ensign is laid up in St Mary's parish church in the town of Rye, East Sussex.

The Rye and District Sea Cadets maintain the traditions of HMS Rye.

Phaeodactylum. Phaeodactylum tricornutum is a diatom, the only species in the genus Phaeodactylum. Unlike other diatoms, P. tricornutum can exist in different morphotypes (fusiform, triradiate, and oval) and changes in cell shape can be stimulated by environmental conditions. This feature can be used to explore the molecular basis of cell shape control and morphogenesis. Unlike most diatoms, P. tricornutum can grow in the absence of silicon and can survive without making silicified frustules. This provides opportunities for experimental exploration of silicon-based nanofabrication in diatoms.

Another peculiarity is that during asexual reproduction the frustules do not appear to become smaller. This allows continuous culture without need for sexual reproduction. It is not known if P. tricornutum can reproduce sexually. To date no substantial evidence has been found to support sexual reproduction in a laboratory or other setting. Although P. tricornutum can be considered to be an atypical pennate diatom, it is one of the main diatom model species. A transformation protocol has been established and RNAi vectors are available. This makes molecular genetic studies much easier.

History

Phaeodactylum tricornutum was first described in the triradiate morphotype by Bohlin in 1897. Recordings of the first cultures of P. tricornutum were published by Allen and Nelson in 1910, although it was misidentified as Nitzschia colsterium,W. Sm., forma miuntissima. The isolate was later correctly revised as P. tricorntum by J.C. Lewin in 1958. This strain among other later isolates are still maintained in culture collections around the world.

Genome sequencing
Phaeodactylum tricornutum is one of a handful of diatoms whose genome has been sequenced. As of 2023, P. tricornutum is the only diatom for which a telomere-to-telomere genome assembly exists. P. tricornutum is a diploid with 25 pairs of nuclear chromosomes.

P. tricornutum has emerged as a potential microalgal energy source. It grows rapidly and storage lipids constitute about 20-30% of its dry cell weight under standard culture conditions. Nitrogen limitation can induce neutral lipid accumulation in P. tricornutum, indicating possible strategies for improving microalgal biodiesel production.

Gwilym Jenkins. Gwilym Meirion Jenkins (12 August 1932 – 10 July 1982) was a Welsh statistician and systems engineer, born in Gowerton (), Swansea, Wales. He is most notable for his pioneering work with George Box on autoregressive moving average models, also called Box–Jenkins models, in time-series analysis.

He earned a first class honours degree in mathematics in 1953 followed by a PhD at University College London in 1956. After graduating, he married Margaret Bellingham and together they raised three children. His first job after university was junior fellow at the Royal Aircraft Establishment. He followed this by a series of visiting lecturer and professor positions at Imperial College London, Stanford University, Princeton University, and the University of Wisconsin–Madison, before settling in as a professor of Systems Engineering at Lancaster University in 1965. His initial work concerned discrete time domain models for chemical engineering applications.

While at Lancaster, he founded and became managing director of ISCOL (International Systems Corporation of Lancaster). He remained in academia until 1974, when he left to start his own consulting company.

He served on the Research Section Committee and Council of the Royal Statistical Society in the 1960s, founded the Journal of Systems Engineering in 1969, and briefly carried out public duties with the Royal Treasury in the mid-1970s. He was elected to the Institute of Mathematical Statistics and the Institute of Statisticians.

He was a jazz and blues enthusiast and an accomplished pianist.

He died from Hodgkin's lymphoma in 1982.
