Analog signature analysis. Analog signature analysis is an electronic component and circuit board troubleshooting technique which applies a current-limited AC sine wave across two points of an electronic component or circuit. 

The resulting current/voltage waveform is shown on a signature display using vertical deflection for current and horizontal deflection for voltage. This unique analog signature represents the overall health of the part being analyzed. By comparing the signatures of known good circuit boards to those of suspect boards, faulty nets and components can be quickly identified.

Analog signature analysis relies on a change in electrical characteristics to detect problems on a circuit board.

Business Intelligence 2.0. Business Intelligence 2.0 (BI 2.0) is a development of the existing business intelligence model that began in the mid-2000s, where data can be obtained from many sources. The process allows for querying real-time corporate data by employees but approaches the data with a web browser-based solution. This is in contrast to previous proprietary querying tools that characterized previous BI software.

Overview
The growth in service-oriented architectures (SOA) is one of the main factors for the development of BI 2.0, which is intended to be more flexible and adaptive than normal business intelligence. Data exchange processes also differ, with XBRL (Extensible Business Reporting Language), Web Services , and various Semantic Web ontologies enabling the use of data external to an organization, such as benchmarking-type information. In addition, BI 2.0 facilitates the integration of real-time data, allowing businesses to react to market changes more swiftly than traditional systems. This has made BI 2.0 particularly valuable in industries requiring rapid decision-making, such as finance and e-commerce.

Business Intelligence 2.0 is believed to have been named after Web 2.0, although it takes elements from both Web 2.0 (a focus on user empowerment and community collaboration, technologies like RSS, and the concept of mashups), and the Semantic Web, sometimes called "Web 3.0" (semantic integration through shared ontologies to enable easier exchange of data).

According to analytics expert Neil Raden, BI 2.0 also implies a move away from the standard data warehouse that business intelligence tools have used, which "will give way to context, contingency, and the need to relate information quickly from many sources."

Oriel Wind Farm. Oriel Wind Farm is a proposed offshore wind farm in the northwestern Irish Sea.  The project is associated with Oriel Windfarm Limited, a privately owned Irish renewable energy company.

According to a 2007 press release, the proposed farm is due to be located near Clogherhead, approximately  southeast of Dundalk, County Louth, and approximately  northeast of Drogheda.  The farm takes its name from the ancient Kingdom of Oriel.

Environmental impact
Detailed surveys and studies of the physical, ecological, and human environment at the proposed wind farm site have been carried out since 2003. These included geotechnical assessments of the area and surveys of birds flying above the site.

Construction
In 2007, the proposed developers suggested that if permission was obtained, "construction could commence as early as Autumn 2009". However, as of 2014, the project was on hold pending talks between the Irish and UK governments on exporting the electricity to the UK.

In July 2015, the companies Oriel Windfarm and Gaelectric announced a proposed co-development of a 15MW demonstration project, to potentially include the development of a research and development hub for offshore energy. The two companies suggested that the project, termed the North Irish Sea Array, had the potential to produce 870MW of electricity.

Output
If completed as per the 2007 proposals, the wind farm would reportedly be capable of generating up to 330 megawatts of electricity. The generated electricity could be fed into the Irish national electrical grid, with some of the output exported via interconnector to the UK and European energy markets.

Linear scheduling method. Linear scheduling method (LSM) is a graphical scheduling method focusing on continuous resource utilization in repetitive activities.

Application
LSM is used mainly in the construction industry to schedule resources in repetitive activities commonly found in highway, pipeline, high-rise building and rail construction projects. These projects are called repetitive or linear projects. The main advantages of LSM over critical path method (CPM) is its underlying idea of keeping resources continuously at work. In other words, it schedules activities in such a way that:

 resource utilization is maximized;
 interruption in on-going process is minimized, including hiring-and-firing; and
 the effect of the learning curve phenomenon is maximized

Alternative names

Specific names for the linear scheduling method have been adopted, such as:
Location-based scheduling (the preferred term in the book)
Harmonograms
Line-of-balance
Flowline or flow line
Repetitive scheduling method
Vertical production method
Time-location matrix model
Time space scheduling method

Sequence step algorithm. A sequence step algorithm (SQS-AL) is an algorithm implemented in a discrete event simulation system to maximize resource utilization. This is achieved by running through two main nested loops: A sequence step loop and a replication loop. For each sequence step, each replication loop is a simulation run that collects crew idle time for activities in that sequence step. The collected crew idle times are then used to determine resource arrival dates for user-specified confidence levels. The process of collecting the crew idle times and determining crew arrival times for activities on a considered sequence step is repeated from the first to the last sequence step.

NISO Circulation Interchange Protocol. NISO Circulation Interchange Protocol (NCIP) is a protocol that is limited to the exchange of messages between and among computer-based applications to enable them to perform functions necessary to lend and borrow items, to provide controlled access to electronic resources, and to facilitate cooperative management of these functions.

Released in May 2001 and approved on October 17, 2002, ANSI/NISO Z39.83-2002 or NCIP is a "NISO Draft Standard for Trial Use." This protocol defines a repertoire of messages and associated rules of syntax and semantics for use by applications: to perform the functions necessary to lend items; to provide controlled access to electronic resources; and to facilitate co-operative management of these functions. It is intended to address conditions in which the application or applications that initiate the lending of items or control of access must acquire or transmit information about the user, items, and/or access that is essential to successful conclusion of the function.

Beuth (locomotive). BEUTH was a 2-2-2 steam locomotive manufactured by Borsig in 1843 and  was the first steam locomotive developed independently in Germany. Borsig had previously built locomotives based on American models. The locomotive won a race against a model by Stephenson by about ten minutes and was considered the prototype of fast German locomotive designs for the next ten years. A driving axle and two running axles as well as a vertical boiler ensured comparatively high speeds. It was named after the head of the Prussian trade academy Christian Peter Wilhelm Beuth, who had prophesied to August Borsig that nothing would ever come of it. A replica of the locomotive is currently on display in the German Museum of Technology in Berlin.

Technical specifications

Compared to the Adler, the Beuth had larger cylinders mounted externally. This meant that a crank axle that was difficult to manufacture could be dispensed with. The connecting rods of the cylinders acted directly on the driving wheels located in the middle using eccentrically mounted crank pins pressed into the wheel spoke system. This meant that the crank pin and connecting rod bearings with the highest shear forces were more easily accessible for lubricating and inspection. The higher steam consumption of the engine required a more powerful and larger steam boiler in the form of a long boiler and a vertical boiler with a high steam dome. This cupola-like boiler is typical of all early Borsig designs such as the Borsig and the Borussia that followed the Beuth. The rear wheel set under the open driver's cab of the Beuth is also found in many later designs. The Beuth was actually the first steam locomotive to be produced in series with classic features that were used in almost all later designs worldwide.

The locomotive's design included bar frames and a 2-2-2 wheel arrangement.

History
Named after a teacher of August Borsig at the , the Beuth was the 24th locomotive built by the manufacturer. Beuth ended up being a great success, and its valve design became de facto standard for locomotives for decades to come. The original locomotive was scrapped.

The Beuth was displayed at the Berlin Trade Exhibition in 1844 and then operated by the Berlin-Anhalt Railway. A total of 71 examples of this design were produced in a kind of series and they were used throughout northern Germany. A further development of the Beuth by Borsig went in service as Borussia from 1844 e.g. delivering services on the Cologne-Minden Railway; other manufacturers at the time took the Beuth as a prototype.

Replica
A replica of the locomotive was constructed in 1912, which is exhibited in the German Museum of Technology in Berlin.

Moseley Iron Bridge and Roof Company. 

The Moseley Iron Bridge Company was founded by Thomas William Moseley in Cincinnati, Ohio around 1858 and existed until 1879.  Moseley was an engineer, bridge builder, and designer.  John Paul Verree used T.W.H. Moseley's designs for his bridge manufacturing business in Philadelphia, Pennsylvania.

History
Zenas King was hired by Moseley as a salesperson and represented Moseley at many bridge lettings, mainly in southern Ohio.  King remained in Ohio and started his own bridge building business in Cleveland. In 1861, Moseley decided to move the company to Boston, Massachusetts.  Moseley moved his business to Boston when he discovered marketing his iron bridge designs were ideal for areas in the New England area. The company was also known as the Moseley Iron Bridge Works of Boston.
 
The company changed names and locations several times between 1858 and 1879, including Philadelphia and New York.

Arthur Newell Talbot. Arthur Newell Talbot (October 21, 1857 –April 3, 1942) was an American civil engineer.  He made many contributions to several engineering fields including structures, sewage management, and education.  He is considered to be a pioneer in the field of reinforced concrete.

Biography

Early life and education
Talbot was born on October 21, 1857, at Cortland, Illinois.  His elementary education was in Cortland, and he attended high school in nearby Sycamore.  After graduation from high school, he taught in a country school for two years.

He enrolled at Illinois Industrial University (now the University of Illinois Urbana-Champaign) in 1877 to study civil engineering.  He was a brilliant student and also participated in many extracurricular activities.  He was secretary, vice president and president of the Philomathean Literary Society, associate editor of the Illini delegate to the Interstate Oratorical Association, class essayist, a leading officer in the student government, and an officer in the Cadet Corps.  He graduated from the university in 1881.

Career
After graduation, Talbot headed west and did railroad construction and maintenance in Colorado, Idaho, Kansas, and New Mexico.  In September 1885, he returned to the University of Illinois as an assistant professor of engineering and mathematics.  He taught a wide range of subjects, which at different times included mathematics, surveying, engineering drawing, contracts and specifications, roads and pavements, railroad engineering, mechanics and materials, hydraulics, tunneling and explosives, and water supply and sewerage.

In 1890, he was named Professor of Municipal and Sanitary Engineering in charge of Theoretical and Applied Mechanics.  Around this time, engineering schools began expanding rapidly, and engineering materials and mechanics began to attract his attention even more than sanitary engineering.  Without ever changing his title, the emphasis of his work continued to be placed on mechanics and materials.

In 1926, he retired and was named Professor of Municipal and Sanitary Engineering, Emeritus.

Personal life
Talbot married Virginia Mann Hammet in Camargo, Illinois, on June 7, 1886.  They had 4 children together.  She died on December 4, 1919.

Rankine theory. Rankine's theory (maximum-normal stress theory), developed in 1857 by William John Macquorn Rankine, is a stress field solution that predicts active and passive earth pressure. It assumes that the soil is cohesionless, the wall is frictionless, the soil-wall interface is vertical, the failure surface on which the soil moves is planar, and the resultant force is angled parallel to the backfill surface.  The equations for active and passive lateral earth pressure coefficients are given below. Note that φ' is the angle of shearing resistance of the soil and the backfill is inclined at angle β to the horizontal.

 

 

For the case where β is 0, the above equations simplify to

Rankine theory 
Rankine's Theory says that failure will occur when the maximum principal stress at any point reaches a value equal to the tensile stress in a simple 
tension specimen at failure. This theory does not take into account the effect of the other two principal stresses.  Rankine's theory is satisfactory for brittle materials, and not applicable to ductile materials.  This theory is also called the Maximum Stress Theory.

Active and passive soil pressures

This theory, which considers the soil to be in a state of plastic equilibrium, makes the assumptions that the soil is homogeneous, isotropic and has internal friction. The pressure exerted by soil against the wall is referred to as active pressure. The resistance offered by the soil to an object pushing against it is referred to as "passive pressure". Rankine's theory is applicable to incompressible soils. The equation for cohesionless active earth pressure is expressed as:

 

where:

 

and:

 Ka = Coefficient of active pressure

 w = weight density of soil

 h = depth of the section (below top soil) where the pressure is being evaluated.

 β = angle that the top surface of soil makes with the horizontal.

 φ = angle of internal friction of soil.

The expression for passive pressure is:

 

where:

 
 Or in the case of β=0, then the two coefficients are inversely proportional, such that:
