Data extraction. Data extraction is the act or process of retrieving data out of (usually unstructured or poorly structured) data sources for further data processing or data storage (data migration). The import into the intermediate extracting system is thus usually followed by data transformation and possibly the addition of metadata prior to export to another stage in the data workflow.

Usually, the term data extraction is applied when (experimental) data is first imported into a computer from primary sources, like measuring or recording devices. Today's electronic devices will usually present an electrical connector (e.g. USB) through which 'raw data' can be streamed into a personal computer.

Data sources
Typical unstructured data sources include web pages, emails, documents, PDFs, social media, scanned text, mainframe reports, spool files, multimedia files, etc. Extracting data from these unstructured sources has grown into a considerable technical challenge, where as historically data extraction has had to deal with changes in physical hardware formats, the majority of current data extraction deals with extracting data from these unstructured data sources, and from different software formats. This growing process of data extraction from the web is referred to as "Web data extraction" or "Web scraping".

Imposing structure
The act of adding structure to unstructured data takes a number of forms
 Using text pattern matching such as regular expressions to identify small or large-scale structure e.g. records in a report and their associated data from headers and footers; 
 Using a table-based approach to identify common sections within a limited domain e.g. in emailed resumes, identifying skills, previous work experience, qualifications etc. using a standard set of commonly used headings (these would differ from language to language), e.g. Education might be found under Education/Qualification/Courses;
 Using text analytics to attempt to understand the text and link it to other information

Joins (concurrency library). Joins is an asynchronous concurrent computing API (Join-pattern) from Microsoft Research for the .NET Framework. It is based on join calculus and makes the concurrency constructs of the Cω language available as a CLI assembly that any CLI compliant language can use.

Overview
Joins can be used to express concurrency in an application using the joins pattern, usable both for multi-threaded applications as well as for event based distributed applications. The Joins API emulates declarative type-safe expression of synchronization patterns. 

The Joins library emulates asynchronous and synchronous methods. An asynchronous method, in Cω and Joins parlance, is one which does not block the caller method, nor does it return any result, whereas a synchronous method blocks the caller method. In the Joins API, synchronous as well as asynchronous methods are implemented as generic delegates. Usage of generics provide type safety. For example, a set of synchronous and asynchronous method can be created and using them to create an object that implements the pattern, as:
public class JoinDemo
{
    public readonly Asynchronous.Channel<int> Queue;
    public readonly Asynchronous.Channel<string> Send;
    public readonly Synchronous<int>.Channel Retrieve; 
    private Join joinPattern = Join.Create();
    
    public JoinDemo()
    {
        joinPattern.Initialize(out Queue);
        joinPattern.Initialize(out Send);
        joinPattern.Initialize(out Retrieve);
    }
}

When asynchronous methods are called, the parameters are put in a channel, which is a queue managed by the Joins runtime. The method can optionally start a new thread to process the parameters in the background, and return the results. When the corresponding synchronous method is called the parameter is returned for further processing. If no parameter is present in the queue when the synchronous method is called, the caller stalls. The Joins runtime schedules which parameter is returned based on whether it is ready.

The synchronization pattern of the methods are defined by joins patterns, which describes what happens when a set of channels are invoked. For example, what happens when Send and Retrieve are called together can be different than Send and Queue.

public void SetPatterns()
{
    join.When(Send).And(Retrieve).Do(s => s);
    join.When(Queue).And(Retrieve).Do(n => n.ToString());
    join.When(Send).And(Queue).And(Retrieve).Do(s => 
                                                {
                                                    Send(s);
                                                    return Retrieve();
                                                });
}

Systems analyst. A systems analyst, also known as business technology analyst, is an information technology (IT) professional who specializes in analyzing, designing and implementing information systems. Systems analysts assess the suitability of information systems in terms of their intended outcomes and liaise with end users, software vendors and programmers in order to achieve these outcomes. A systems analyst is a person who uses analysis and design techniques to solve business problems using information technology. Systems analysts may serve as change agents who identify the organizational improvements needed, design systems to implement those changes, and train and motivate others to use the systems.

Industry 

, the sectors employing the greatest numbers of computer systems analysts were state government, insurance, computer system design, professional and commercial equipment, and company and enterprise management. The number of jobs in this field is projected to grow from 487,000 as of 2009 to 650,000 by 2016. According to the U.S. Bureau of Labor Statistics (BLS), Occupational Outlook predicts the need for Computer Systems Analysts as growing 25% in 2012 to 2022 and gradually decreasing their estimates and now predict the years 2022 to 2032 as only 10% growth. Saying "Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire."

This job ranked third best in a 2010 survey, fifth best in the 2011 survey, 9th best in the 2012 survey and the 10th best in the 2013 survey.

PRC (file format). PRC (Product Representation Compact) is a file format that can be used to embed 3D data in a PDF file.

This highly compressed format facilitates the storage of different representations of a 3D model. For example, it is possible to save only a visual representation that consists of polygons (a tessellation), and it is also possible to save the model's exact geometry (B-rep data). Varying levels of compression can be applied to the 3D CAD data when it is converted to the PRC format using Adobe Acrobat 3D.

The 3D data stored in PRC format in a PDF is interoperable with Computer-Aided Manufacturing (CAM) and Computer-Aided Engineering (CAE) applications.

History
The PRC file format was first presented by TTF (Trade and Technologies France) in 2003 at DMS in Tokyo. In 2006, the TTF company was acquired by Adobe Systems. In 2014, the PRC file format was approved as an international standard (ISO 14739-1:2014).

Austro-Daimler 6. The  Austro-Daimler 6 was a series of Austrian six-cylinder water-cooled inline aero engines first produced in 1910 by the Austro-Daimler company.

Design and development
The first Austro-Daimler six-cylinder engine was designed by Dr-Ing Ferdinand Porsche to be an aircraft engine from the outset. Of high quality manufacture, the Austro-Daimler was modestly rated at relatively low rpm, which gave the engine family a reputation for robustness and reliability.

Features of the Austro-Daimler included welded steel water jackets (originally copper), seven main bearings and large diameter inclined inlet and exhaust valves opened by dual action push-pull rods and closed by spring pressure. 

The single-overhead cam (SOHC) valvetrain of later engines was driven from the crankshaft through the usual vertically-oriented shaft as the contemporary Mercedes D.III was, but the Austro-Daimler had its vertical camshaft drive system mounted at the front of the engine instead, and not the usual aft-end placement of other Central Powers straight-six SOHC liquid-cooled aircraft powerplants, like the Mercedes and BMW designs.  

The Austro-Daimler inspired many imitators such as the Mercedes D.II, Benz Bz.IV and Hiero 6. Limited availability of the Austro-Daimler engines forced some aircraft manufacturers to substitute Mercedes (the German Daimler company) engines in their aircraft, due to greater availability. From 1913, the 90 and 120 hp models were produced under license in Scotland by William Beardmore and Company. The Beardmore 120 hp went on to power many British military aircraft during WW1.

Xsgi. Xsgi is the X Window System (X11) server for the IRIX-based graphical workstations and servers from Silicon Graphics (SGI).  Xsgi was released in 1991 with IRIX 4.0 on the SGI Indigo workstation.

History
Work on Xsgi began in May 1989 when Tom Paquin left IBM to join SGI to integrate the X Window System with SGI's IRIS GL interface.  Paquin recruited a set of software engineers experienced in X server implementation: Jeff Weinstein, Erik Fortune, Paul Shupak, John Giannandrea, Peter Daifuku, Michael Toy, Todd Newman, Spence Murray, and Dave Spalding.

Graphics hardware designed by Silicon Graphics provides accelerated rendering access through graphics hardware commands rather than memory-mapped framebuffers manipulated by the CPU.  This makes the Monochrome FrameBuffer (MFB) and Color FrameBuffer (CFB) device-dependent rendering layers supplied with the MIT X11 Sampler Server inappropriate for Silicon Graphics hardware. Jeff Weinstein developed the No FrameBuffer (NFB) device-dependent rendering layer to support the Silicon Graphics style of hardware access. SCO later incorporated the NFB layer in its X server porting layer.

Silicon Graphics hardware includes overlay planes to provide a hardware overlay. Initial efforts by Todd Newman to implement overlay plane support in Xsgi eventually led to Peter Daifuku's "fully functional" support for overlay planes. Daifuku separated the notion of a window's visibility clipping region from the window's renderable clipping region. The previous MIT X sample server treats these two clipping regions as being the identical region. Xsgi advertises overlay planes as X11 visuals with their overlay characteristics described by the  convention.

Erik Fortune developed the X keyboard extension (XKB) for Xsgi.

Xsgi supports the X11, IRIS GL, OpenGL, Display PostScript, and PEX PHIGS rendering models.

Howland's Michigan Engineers Company. Howland's Michigan Engineers Company, or the Battle Creek Engineer Corps, was an engineer company that served in the Union Army during the American Civil War.

Service
The company  was organized at Battle Creek, Michigan on September 16, 1861, and mustered into Federal Service on October 9, 1861.  However, when Major General H.W. Halleck took command of the Department of Missouri, he decided that Howland's Company did not meet federal organizational standards.  Upon notification of this fact, the company voted to disband and were subsequently mustered out of Federal Service on January 8, 1862.

Total strength and casualties
Over its existence, the regiment carried a total of 53 men on its muster rolls.
