Aviméta 88. The Aviméta 88 was an all-metal French two-seat reconnaissance-fighter or heavy fighter tested in 1927.

Design and development 

Aviméta, (Société pour la Construction d'Avions Métallique)‚ grew out of the Aeronautical Department of the Schneider-Creusot arms manufacturer.  Both the frame and the corrugated covering of the Aviméta 88 were made from Alferium, an aluminium-iron alloy developed by Schneiders.

It was a parasol aircraft, with wings of constant chord and with slightly pointed, semi-elliptical tips. The thin-airfoil-section wings were built around two lattice girder spars and had a skin thickness of 300 μm.  There was a large, trapezoidal cut-out in the trailing edge to improve the view from the cockpits.  Its aileron hinges were set at a shallow angle to the trailing edge.

The wings were braced to the fuselage with a parallel pair of struts from the lower longerons to the spars at about mid-span assisted by N-form, cross-braced jury struts at right angles. Four very short struts from the upper fuselage longerons to the wing centre section formed a low cabane.

The square-section, rounded-cornered fuselage was built around these four longerons and a set of diagonally braced formers.  The Aviméta's  Hispano-Suiza 12Hb water-cooled V-12 engine was in a pointed nose, driving a two-blade propeller.  There were two open cockpits, with the pilot forward at mid-chord and the gunner/observer behind in line with the trailing edge.  Behind the cockpits the fuselage tapered rapidly in profile to a conventional empennage, with the tailplane mounted at mid-fuselage.  Both horizontal and vertical surfaces were strongly tapered, particularly on the leading edges, with a broad tailplane and fin but with small, inset elevators and rudder. The Aviméta 88 had independent bungee-sprung wheels on legs enclosed in tapered trouser fairings attached to the lower longerons at the bottom of the wing struts.

The Aviméta 88 was on show at the December 1926 Paris Aero Salon. It may not have flown by that date, and rather little is known about its later history, though it gave a "pretty impressive" display at Villacoublay in September 1927.  Development was terminated when the official call for a two-seat fighter-reconnaissance aircraft was rescinded.

MBrace. MBrace is a .NET open-source framework and runtime which introduces a novel programming model for performing large scale computations in public, private and hybrid cloud computing environments. MBrace is inspired by the programming paradigm of asynchronous workflows as introduced in the F# programming language while borrowing ideas from CloudHaskell and HdpH. MBrace is written entirely in F# and provides bindings for F# and C#.

Overview 
MBrace is a programming model and framework powered by the .NET software stack that is suitable for distributed programming. Based on the F# programming language, it offers an expressive and integrated way of developing, deploying and debugging large-scale computations running in cloud environments. MBrace is capable of distributing arbitrary code and offers native access to the rich collection of tested libraries offered with the underlying .NET framework. MBrace draws heavy inspiration from the Haskell community, especially from the work on concurrency/parallelism and shares many similar ideas with the HdpH project. Its programming model is founded on the premise that monads, in a recursive higher-order language, offer a rich substrate for expressing many different kinds of algorithmic patterns (i.e.: MapReduce, streaming, iterative or incremental algorithms) which can be defined at the user level as libraries, without the need to change any underlying runtime infrastructure.

Distinguishing features 
MBrace offers a series of unique features such as:

 Bigger scope: MBrace provides a unified experience for authoring various kinds of algorithms. While other frameworks focus on more specific algorithms or patterns (e.g. MapReduce, actors). MBrace provides such algorithms as extensions (i.e.: the workflow library implementing MapReduce) which can be combined and tweaked by the users.
 Centralized deployment, monitoring and debugging: MBrace provides a shell that can be used for centralized monitoring and deployment without the need of batch files, manual copying, etc.
 Concise and succinct algorithm development: The code developed using MBrace is not cluttered by orchestration details which makes code maintenance and debugging less cumbersome while its programming model enables less experienced users to tackle with big data and HPC algorithms.

Dibromine monoxide. Dibromine monoxide is the chemical compound composed of bromine and oxygen with the formula Br2O. It is a dark brown solid which is stable below −40 °C and is used in bromination reactions. It is similar to dichlorine monoxide, the monoxide of its halogen neighbor one period higher on the periodic table. The molecule is bent, with C2v molecular symmetry. The Br−O bond length is 1.85 Å and the Br−O−Br bond angle is 112°, similar to dichlorine monoxide.

Reactions
Dibromine monoxide can be prepared by reacting bromine vapor or a solution of bromine in carbon tetrachloride with mercury(II) oxide at low temperatures:

2 Br2 + 2 HgO → HgBr2·HgO + Br2O

It can also be formed by thermal decomposition of bromine dioxide or by passing an electrical current through a 1:5 mixture of bromine and oxygen gases.

MV H. Lee White. M/V H. Lee White is a diesel-powered Lake freighter owned and operated by the American Steamship Company (ASC). This vessel was built in 1974 at Bay Shipbuilding Company, Sturgeon Bay, Wisconsin and included self-unloading technology.

The ship is  long and  wide, with a carrying capacity of 35,400 tons (at midsummer draft), limestone, grain, coal or iron ore.

History 
The ship was built for American Steamship in 1974 and was named H. Lee White for former chairman Harris Lee White.

On September 6, 1992, H. Lee White struck the Grosse Ile Toll Bridge knocking off one of the spans. Damage to the bridge was around $1.7 million for repairs and lost toll revenue. Courts initially ruled the bridge company 100% liable as they did not open the bridge as promised. On appeal, the judgement was reversed and sent back to the district court for re-evaluation of liability. In 2006, the ship and American Steamship were found 3% liable, as the port anchor could have been deployed to potentially avoid the collision. The bridge company was found 97% liable for not opening the bridge in a timely manner as promised and requested.

Exchange spring media. Exchange spring media (also exchange coupled composite media or ECC) is a magnetic storage technology for hard disk drives that allows to increase the storage density in magnetic recording. The idea, proposed in 2004 by Suess et al., is that the recording media consists of exchange coupled soft and hard magnetic layers. Exchange spring media allows a good writability due to the write-assist nature of the soft layer. Hence, hard magnetic layers such as FePt, CoCrPt-alloys or hard magnetic multilayer structures can be written with conventional write heads. Due to the high anisotropy these grains are thermally stable even for small grain sizes. Small grain sizes are required for high density recording. The introduction of the soft layer does not decrease the thermal stability of the entire structure if the hard layer is sufficiently thick. The required thickness of the hard layer for best thermal stability is the exchange length of the hard layer material.
The first experimental realization of exchange spring media was done on Co-PdSiO multilayers as the hard layer which was coupled via a PdSi interlayer to a FeSiO soft layer.

Besides the improved writeability, another advantage of exchange spring media is, that the switching field distribution of the grains, which has to be as small as possible to allow for high storage densities, can be decreased. This effect was predicted theoretically and experimentally verified on Co/Pd multilayers as hard layer coupled to Co/Ni multilayers as soft layer.
In commercial hard disks exchange spring media is used since about 2007.

TFX Program. The United States Air Force and Navy were both seeking new aircraft when Robert McNamara was appointed U.S. Secretary of Defense in January 1961. The aircraft sought by the two armed services shared the need to carry heavy armament and fuel loads, feature high supersonic speed, twin engines and two seats, and probably use variable geometry wings. On 14 February 1961, McNamara formally directed the services to study the development of a single aircraft that would satisfy both requirements. Early studies indicated that the best option was to base the design on the Air Force requirement, and use a modified version for the Navy. In June 1961, Secretary McNamara ordered the go ahead of Tactical Fighter Experimental (TFX) despite Air Force and Navy efforts to keep their programs separate.

Proposals were received from Boeing, General Dynamics, Lockheed, McDonnell, North American and Republic. The evaluation group found all the proposals lacking, but Boeing and General Dynamics were selected to submit enhanced designs. The Boeing 818 was recommended by the selection board in January 1962, with the exception of the engine, which was not considered acceptable. Switching to a crew escape capsule instead of ejection seats and alterations to radar and missile storage were also needed. Both companies provided updated proposals in April 1962. Air Force reviewers favored Boeing's offering, while the Navy found both submissions unacceptable for its operations. Two more rounds of updates to the proposals were conducted, with Boeing being picked by the selection board.

In November 1962, McNamara selected General Dynamics' proposal due to its greater commonality between Air Force (F-111A) and Navy (F-111B) versions. The Boeing aircraft shared less than half of the major structural components. General Dynamics signed the TFX contract in December 1962. A Congressional investigation followed, but could not change the selection. The winning proposal later became the General Dynamics F-111 Aardvark.

DUP programming language. DUP (DataUnit Processing language) is a special-purpose, interpreted and functional programming language. The DUP language looks like a mixture of C and ASN.1. It borrows its structure from C, while the way of using variables comes from ASN.1. This makes it intuitive for a programmer used to C/C++ and ASN.1 to use the language. It was developed at Ericsson, and used in Ericsson Billing Gateway and Ericsson Multi Activation platform.

Language

Functions 
A function is declared as follows:

<return type> <function name> ( <argument list> )
{
  <function body>
}

The <return type> is one of the ASN.1 types supported by the application in which is used.
It is possible to add CONST to the type which implies that the return value is constant and can not be changed. A function can also have the return type VOID which means that it does not return anything.

The <argument list> is a comma separated list of arguments.
Each argument is declared as follows:
<argument name> <argument type>
The <argument type> is an ASN.1 data type. It is
also possible to use the ANY type if the type is unknown.
All return values and arguments are passed as reference.

An example of DUP code can be seen below:

CONST INTEGER add(a CONST INTEGER)
{
  declare result INTEGER;
  result ::= 10;
  result += a;
  return result;
}

Value Delivery Modelling Language. Value Delivery Modeling Language (VDML) is a standard modeling language for analysis and design of the operation of an enterprise with particular focus on the creation and exchange of value.

In 2009, the Object Management Group (OMG) launched a Request for Proposal (RfP) to develop a standard for value modeling. The goal of this RfP is to integrate the different existing value models and give a complete overview of the business logic of an organisation. To reach this goal, the standard has to satisfy nine requirements:
 The metamodel must satisfy the characteristics of the Meta-Object Facility (MOF) metamodel. MOF is a standard developed for model-driven engineering and is structured in 4 layers. The top layer (M3 model) consists of a language that is used to construct metamodels. These metamodels are the second layer (M2 model) and they describe the third layer (M1 laer). The last layer, the data layer is used to describe real objects. 
 The metamodel must support the analysis of the activities of the value chain to support the identification of differentiators. The internal value chain should as such be part of the metamodel.
 A capability analysis must be possible. This is closely linked to the second requirement. A capability is the possibility to execute some sort of activity. The quality of an activity is as such dependent on the capabilities of the organisation. As such the metamodel should include a way to analyse these capabilities.
 The value model should have an adequate level of detail to include both activities and capabilities on the operational level. However a value model focuses on the inputs and outputs unlike a process model such as BPMN. 
 The value model should be able to aggregate activities at multiple levels to analyse them from different angles (e.g. strategic vs operational).
 It should be possible to couple performance- and cost aspects to the activities
 The relationships with other organisations such as competitors and strategic alliances should be included.
 The events that trigger an activity should be included in the metamodel
 The user should be able to include its own specifications.

The VDML standard integrates 7 existing value models:
 Porter's Value Chain
 Business Model Ontology of Osterwalder
 Verna Allee's Value Network Analysis
 E3-Value analysis
 Resources, Events, Agents (REA) analysis
 Value Stream Mapping
 Service-Oriented Business Architecture analysis

The use of VDML diagrams to support business model innovation is discussed in

VDML has been applied to a use case in manufacturing. It demonstrates the use of VDML for modeling and analysis of a proposed change to an
as-is business system.
