Damped machining tools. Damped machining tools refer to a series of machining tool which are damped to suppress severe vibrations during machining process. The damping method includes both active damping method and passive damping tool.

The active damping tools utilize a compensating force to the vibrating object in the reversed vibrating direction. Normally, piezoelectric devices are the common apparatus for researchers when developing active damping tools.

The passive damping tools can be divided into constrained layer damping tools and tuned mass dampers. The tuned mass dampers transmit the vibration energy to an extra unit on the structure and maintain the unit under focus to be stable. One typical example is the SilentTools provided by Sandvik Coromant in Sweden.

Development
The technology is developed by researchers in Norway. The constrained layer damping tools usually apply high damping material in the tool end's clamping interface, at specific areas where vibration strain energy concentrates. Typical examples refer to Mircona AB's product series Zero Vibration Tooling developed by the research group led by Cornel-Mihai Nicolescu, in Royal Institute of Technology in Sweden. Lorenzo Daghini, a PhD student of Prof. Cornel-Mihai Nicolescu participated mainly in the development process and finished his PhD thesis along with the development process.

SQuORE. SQUORE is a software analytics and static code analysis tool for software projects. It gathers information from different artefacts types (e.g. source code, test results, bug tracking system) and tools (reads outputs of Checkstyle, PMD, FindBugs, Polyspace, Coverity or SonarQube) and publishes a summarised view of the project quality or progress.

The quality model used for analysis is fully customisable, and many different quality models have been implemented: SQALE, ISO9126 maintainability, European Cooperation for Space Standardization or HIS Automotive group. It is used in the industry and academic research for software engineering and data mining related concerns.

History 

Squore was initially developed by  Squoring Technologies, a French software editor founded in 2010 in Toulouse and specialized in the evaluation and monitoring of software and systems development projects..

In June 2018, Vector Informatik acquired Squoring Technologies and is now the owner of the Squore tool.

Common uses 
The main goal of Squore's software analysis is the assessment of quality characteristics like maintainability, reliability or maturity. Software quality is subject to many definitions and debates; hence evaluation, sub-characteristics and metrics used will differ depending on the context of the analysis: e.g. critical flight systems, medical devices, desktop products.

Contract management may rely on code analysis to define levels of quality between contractors: e.g. cloning ratio, complexity of functions, specific ratings. By using such constraints stakeholders may accept or refuse a delivery based on the analysis result of the product.

Mixed criticality. A mixed criticality system is a system containing computer hardware and software that can execute several applications of different criticality, such as safety-critical and non-safety critical, or of different safety integrity level (SIL). Different criticality applications are engineered to different levels of assurance, with high criticality applications being the most costly to design and verify. These kinds of systems are typically embedded in a machine such as an aircraft whose safety must be ensured.

Principle
Traditional safety-critical systems had to be tested and certified in their entirety to show that they were safe to use. However, many such systems are composed of a mixture of safety-critical and non-critical parts, as for example when an aircraft contains a passenger entertainment system that is isolated from the safety-critical flight systems. Some issues to address in mixed criticality systems include real-time behaviour, memory isolation, data and control coupling.

Computer scientists have developed techniques for handling systems which thus have mixed criticality, but there are many challenges remaining especially for multi-core hardware.

Priority and criticality 
Basically, most errors are currently committed when making confusion between priority attribution and criticality management. As priority defines an order between different tasks or messages to be transmitted inside a system, criticality defines classes of messages which can have different parameters depending on the current use case. For example, in case of car crash avoidance or obstacle anticipation, camera sensors can suddenly emit messages more often, and so create an overload in the system. That is when we need to make Mixed-Criticality operate : to select messages to absolutely guarantee on the system in these overload cases.

Aeros Profi. The Aeros Profi is a Ukrainian high-performance ultralight trike wing, designed and produced by Aeros of Kyiv. The wing is widely used on Aeros trikes as well as by other ultralight aircraft manufacturers.

Design and development
The base model Profi wing is a cable-braced, king post-equipped hang glider-style wing for two-place trikes, while the Profi TL is a "topless" design, lacking the king post and using streamlined lower lift struts instead of wires. The topless design lowers the overall height of the wing and allows storage in lower-roofed hangars. A carbon fibre leading edge insert is optional, while winglets are standard on the TL model.

The wing is made from bolted-together aluminium tubing, with its double surface wing covered in Dacron sailcloth. Its  span wing has an area of  , a nose angle of 128° and uses an "A" frame weight-shift control bar. An electro-mechanical trim is optional.

Apache Storm. Apache Storm is a distributed stream processing computation framework written predominantly in the Clojure programming language. Originally created by Nathan Marz and team at BackType, the project was open sourced after being acquired by Twitter. It uses custom created "spouts" and "bolts" to define information sources and manipulations to allow batch, distributed processing of streaming data. The initial release was on 17 September 2011.

A Storm application is designed as a "topology" in the shape of a directed acyclic graph (DAG) with spouts and bolts acting as the graph vertices. Edges on the graph are named streams and direct data from one node to another. Together, the topology acts as a data transformation pipeline. At a superficial level the general topology structure is similar to a MapReduce job, with the main difference being that data is processed in real time as opposed to in individual batches. Additionally, Storm topologies run indefinitely until killed, while a MapReduce job DAG must eventually end.

Storm became an Apache Top-Level Project in September 2014 and was previously in incubation since September 2013.

Development 
Apache Storm is developed under the Apache License, making it available to most companies to use. Git is used for version control and Atlassian JIRA for issue tracking, under the Apache Incubator program.

Apache Storm architecture 
The Apache Storm cluster comprises following critical components:
 Nodes: There are two types of nodes: Master Nodes and Worker Nodes. A Master Node executes a daemon Nimbus which assigns tasks to machines and monitors their performances. On the other hand, a Worker Node runs the daemon called Supervisor which assigns the tasks to other worker nodes and operates them as per the need. As Storm cannot monitor the state and health of cluster, it deploys ZooKeeper to solve this issue which connects Nimbus with the Supervisors.
 Components: Storm has three critical components: Topology, Stream, and Spout. Topology is a network made of Stream and Spout. Stream is an unbounded pipeline of tuples and Spout is the source of the data streams which converts the data into the tuple of streams and sends to the bolts to be processed.

Peer platforms 
Storm is but one of dozens of stream processing engines, for a more complete list see Stream processing. Twitter announced Heron on June 2, 2015 which is API compatible with Storm. There are other comparable streaming data engines such as Spark Streaming and Flink.

Precision Airborne Standoff Directed Energy Weapon. The Precision Airborne Standoff Directed Energy Weapon was a weapons system described in unclassified documents leaked to Wired magazine in 2007.

In 2008 Boeing tested a prototype of the weapon, mounted in a C-130.

Some commentators compared the military`s requests with fantastical science fiction.
They have repeated passages from the military briefing documents where the weapon was described as like a long distance blow torch.  It was described as being able to erode the morale of enemies by showing the USA had the ability to set suspects on fire from a distance.  It was also described as being able to incapacitate vehicles by bursting their tires, at lower intensity levels.

In 2012 Wired reported that the Naval Criminal Investigation Service was trying to track the individual who leaked the documents, even though they were not classified.

Jean-Baptiste-Pierre le Romain. Jean-Baptiste-Pierre Le Romain (dates of birth and death unknown) was a French engineer and contributor to the Encyclopédie during the eighteenth century and the Age of Enlightenment.

Living in Martinique, in 1734 Le Romain drew up a topographic map of the island for the French government. In 1740 he was sent as an assistant engineer to improve the fortifications of the island of Grenada, where he was appointed chief engineer in 1748.

Le Romain provided nearly seventy articles on the Caribbean between volumes III and XVI of the Encyclopédie of Diderot and D'Alembert. More than half of his articles are short descriptions of production, animals, minerals and geography of the Caribbean islands. He provided more detail of the production of regional products such as indigo, sugar and foods derived from cassava. Le Romain also wrote the entry for 'negroes' which reflects the colonial prejudices against blacks, referring to them as "barbarians".

A competent naturalist, Le Romain's contributions gave Diderot and d'Alembert first-hand information on the Caribbean and thus an expanded view of the world for their Encyclopédie.
