Android Assault: The Revenge of Bari-Arm. Android Assault: The Revenge of Bari-Arm, released in Japan as , is a 1993 shoot 'em up video game developed and published by Human Entertainment for the Sega CD.

Story
Humanity makes advances in space travel and colonization. In the year 2192 however, the colonists near Jupiter are attacked by the independent military nation of Zias stationed on the Olympus colony of Saturn. Zias uses a symbiotic computer system and several mecha factories powered by a device called the GEO as their primary attack force. Human scientists study the Zias technology and, based on the Zias GEO system, became able to build a space fighter capable of fighting against the Zias: the Bari-arm, a space ship capable of using multiple weapons and transforming into a giant robot with the same capabilities as the Zias cyborgs. Bari-arm is piloted by two young pilots with the mission of destroying the new GEO system before the Zias war machines destroy any further colonies and eradicate humanity forever.

Gameplay
Players control the Bari-arm through seven shooting stages. The Bari-arm has four ship speed levels and is equipped with a fully automatic shot and a charge weapon. The charge weapon automatically charges when the player does not hold down the fire button. The charge weapon unleashes a stronger version of whichever weapon the player has equipped. Weapons are collected as icons in the stage. The weapons available to the ship included the Thunder Cracker, Chase Cannon, Burning Wave and the Satellite Bombs. Every weapon covers the front and back of the ship except the Burning Wave, the only primary straight firing weapon.

Reception
GamePro gave the game a negative review, commenting that it is decent but outdated, especially when compared to other CD-based shooters, and is too derivative in every respect to be worthwhile for players who have played any of the dozens of shooters which preceded it. Electronic Gaming Monthly gave it a 6.2 out of 10. They praised the soundtrack but criticized that the graphics are mediocre for a CD-based game.

Company history

In 1947, Charles W. Lerch started a company performing maintenance and repairs, C. W. Lerch Co, (widely accepted as the first independent elevator consulting company) in Chicago. He later added elevator consulting as a side business. In 1964 Charles W. Lerch was joined by Vane Q. Bates and both men working full-time on elevator consulting. The firm moved to its offices to Denver, Colorado that same year and officed downtown in the Patterson Building on 17th Street (since demolished).  The Company moved a number of times but has maintained its HQ in and around Denver.  In 1974 the company was incorporated as Lerch Bates & Associates and by the 1980s building boom, and under the leadership of Quent Bates (CW Lerch having died in the early 1980s)  Lerch Bates had 15 offices in North America. In 1985 Lerch Bates Limited in London was formed and in 1990 it created the first "Performance Related" maintenance contact, which related equipment downtime and traffic performance to maintenance premiums. In 1994 under the direction of Quent Bates and his quest to reward the employees, Lerch Bates became an employee owned company and is now considered one of the best and longest running ESOP's in the US. In 1998 Lerch Bates designed the world's fastest elevators for the then world's tallest building, the Taipei Financial Centre / Taipei 101.

BotSeer. BotSeer was a Web-based information system and search tool used for research on Web robots and trends in Robot Exclusion Protocol deployment and adherence. It was created and designed by Yang Sun, Isaac G. Councill, Ziming Zhuang and C. Lee Giles. BotSeer was in operation from 2007 to 2010, approximately.

History
BotSeer served as a resource for studying the regulation and behavior of Web robots as well as information about the creation of effective robots.txt files and crawler implementations. It was publicly available on the World Wide Web at the College of Information Sciences and Technology at the Pennsylvania State University.

BotSeer provided services including robots.txt searching, robot bias analysis, and robot-generated log analysis. The prototype of BotSeer also allowed users to search 6,000 documentation files and source codes from 18 open source crawler projects.

BotSeer had indexed and analyzed 2.2 million robots.txt files obtained from 13.2 million websites, as well as a large Web server log of real-world robot behavior and related analysis. BotSeer's goals were to assist researchers, webmasters, web crawler developers and others with web robots related research and information needs. However, some people received BotSeer negatively, arguing that it contradicted the purpose of the robots.txt convention.

BotSeer had also had set up a honeypot to test the ethics, performance and behavior of web crawlers.

AlphaIC. AlphaIC is a method for assessing the value of information technology (IT) investments that surpasses banal ROI analyses and looks at how IT affects an organization's intellectual capital.

The methodology was developed in 2003–2004 by technologist Paolo Magrassi and economist Alessandro Cravera, based on the observation of two ongoing trends:

 On one side, research on the information technology (IT) 'productivity paradox’ and the quantitative assessment of IT’s impact as a general purpose technology. This was mainly stimulated by Erik Brynjolfsson’s works in 1998-2002;
 On the other side, research and practitioners’ work on intangible assets (a.k.a. a company's ‘intellectual capital’ ), such as that by Karl-Erik Sveiby at Skandia AV in 1986, Baruch Lev at NYU's Stern in 1996, and Cravera in 1999–2000.

The two trends were merged in order to develop a ‘value of IT’ assessment methodology that go beyond simple return on investment (ROI) analyses as well as other existing methodologies, all unable to capture the true advantage provided by IT.

The methodology is copyrighted, however a simple and concise description, including that of its application in real-world organizations, is to be found in.

7.5 cm FK 38. The 7.5 cm Feldkanone 38 (7.5 cm FK 38) was a field gun used by Germany and Brazil in World War II. Built by Krupp to satisfy an order by the Brazilian Army some 64 were delivered before the war began. In 1942 the remainder of the order was completed and 80 were delivered to the Heer.

Design 
The FK 38 had a longer barrel than the 7.5 cm FK 18 that was fitted with a cylindrical muzzle brake. Originally this was an unusual 6 slot design, but it was later replaced by a standard German four port design. Early versions had wood-spoked wheels, but later models had pressed steel wheels with solid rubber tires and had sprung axles for motor transport. It used a semi-automatic version of the original breech mechanism and fixed ammunition instead of the original separate-loading rounds. These changes likely boosted its rate of fire over the FK 18 considerably.

Hythe Bridge. Hythe Bridge (formerly known as High Bridge) is a Victorian flat cast iron beamed bridge on Hythe Bridge Street in the west of central Oxford, England. It spans the Castle Mill Stream, a backwater of the River Thames. Hythe Bridge forms part of the main arterial route west of Oxford. It lies on the A4144, which continues west as the Botley Road (A420).

The first bridge here, probably of wooden construction, was built by Oseney Abbey in 1200–10. A stone bridge was built in 1383. It was a round-arched bridge with three arches. The current iron bridge was designed by John Galpin, an Oxford-based engineer, in 1861. The name "Hythe" is derived from the "hithe" (wharf) that used to be located by the bridge. "Hithe" is a Saxon word that means a landing place.

Immediately to the northeast of Hythe Bridge is the current southern end of the Oxford Canal. This used to continue south of Hythe Bridge Street to a basin with wharves that in 1951 was filled in and is now a car park and part of Nuffield College.

Glass batch calculation. Glass batch calculation or glass batching is used to determine the correct mix of raw materials (batch) for a glass melt.

Principle
The raw materials mixture for glass melting is termed "batch".  The batch must be measured properly to achieve a given, desired glass formulation. This batch calculation is based on the common linear regression equation:

with NB and NG being the molarities 1-column matrices of the batch and glass components respectively, and B being the batching matrix. The symbol "T" stands for the matrix transpose operation, "−1" indicates matrix inversion, and the sign "·" means the scalar product. From the molarities matrices N, percentages by weight (wt%) can easily be derived using the appropriate molar masses.

Example calculation
An example batch calculation may be demonstrated here. The desired glass composition in wt% is: 67 SiO2, 12 Na2O, 10 CaO, 5 Al2O3, 1 K2O, 2 MgO, 3 B2O3, and as raw materials are used sand, trona, lime, albite, orthoclase, dolomite, and borax. The formulas and molar masses of the glass and batch components are listed in the following table:

The batching matrix B indicates the relation of the molarity in the batch (columns) and in the glass (rows). For example, the batch component SiO2 adds 1 mol SiO2 to the glass, therefore, the intersection of the first column and row shows "1". Trona adds 1.5 mol Na2O to the glass; albite adds 6 mol SiO2, 1 mol Na2O, and 1 mol Al2O3, and so on. For the example given above, the complete batching matrix is listed below. The molarity matrix NG of the glass is simply determined by dividing the desired wt% concentrations by the appropriate molar masses, e.g., for SiO2 67/60.0843 = 1.1151.

            

The resulting molarity matrix of the batch, NB, is given here. After multiplication with the appropriate molar masses of the batch ingredients one obtains the batch mass fraction matrix MB:

               or   

The matrix MB, normalized to sum up to 100% as seen above, contains the final batch composition in wt%: 39.216 sand, 16.012 trona, 10.242 lime, 16.022 albite, 4.699 orthoclase, 7.276 dolomite, 6.533 borax. If this batch is melted to a glass, the desired composition given above is obtained. During glass melting, carbon dioxide (from trona, lime, dolomite) and water (from trona, borax) evaporate.

Simple glass batch calculation can be found at the website of the University of Washington.

Advanced batch calculation by optimization
If the number of glass and batch components is not equal, if it is impossible to exactly obtain the desired glass composition using the selected batch ingredients, or if the matrix equation is not soluble for other reasons (i.e., the rows/columns are linearly dependent), the batch composition must be determined by optimization techniques.

Chyetverikov ARK-3. The Chyetverikov ARK-3 (ARKtichyeskii - arctic) was a multi-role flying boat designed for Arctic operations that was built in the Soviet Union from 1933. It featured a conventional flying boat hull, with high cantilever wings equipped with floats at mid-span. The two piston engines were mounted in tractor-pusher fashion on a pylon above the fuselage.

Development 
In 1933 Chyetverikov had the design for a compact twin engined flying-boat ready for further development, which he proposed to the Glavsyevmorput (Glavsyevmorput – chief administration of northern sea routes) as a multi-role Arctic aircraft, and an order for a prototype was made, setting up Chyetverikov in his own OKB (design bureau).

The ARK-3 was of mixed construction, with a  long Duralumin stressed skin fuselage; wooden wings of MOS-27 aerofoil section; duralumin tubing tail surfaces; and ailerons with fabric covering. The dual control enclosed cockpit housed two pilots sided by side with two gunners/observers in bow and dorsal positions. Strut-supported wooden floats, at approximately half-span; and a pylon-supported engine nacelle housing tandem radial engines with Townend ring cowlings; completed the structural elements, built with a safety factor of 5.5.

Flight- and sea trials in 1936 revealed weaknesses in the bows, floats and engine nacelle pylon, which were all strengthened. Performance was deemed to be good, prompting an order for a second prototype with the fuselage lengthened by  to  and a slightly enlarged wing; this was designated ARK-3-2 and the first prototype was re-designated ARK-3-1. A production order for five aircraft was placed, with production commencing immediately.

On 14 July 1937 the ARK-3-1 was destroyed following a structural failure; the ARK-3-2 was destroyed exactly one year later and the programme was cancelled.

Variants 
ARK-3-1The first prototype ARK-3 renamed after the second prototype was ordered
ARK-3-2The second prototype ARK-3 with more powerful engines, longer hull, increased wing chord and manual guns fitted in a manual gun turret in the bows and a dorsal sliding hatch.
ARK-3 MP2Designation of the five production aircraft and the initial designation of the first prototype.

Dual loop. Dual-loop is a method of electrical circuit termination used in electronic security applications, particularly modern intruder alarms. It is called 'dual-loop' because two circuits (alarm and anti-tamper) are combined into one using resistors.  Its use became widespread in the early 21st century, replacing the basic closed-circuit system, mainly because of changes in international standards and practices.

Dual-loop allows the burglar alarm control panel to read the values of end-of-line resistors for the purpose of telling a zone's status. For example: if an alarm system's software uses 2K ohms as its non-alarm value, an inactive detector will give a reading of 2K ohms as the circuit is passing through just one resistor. When the detector goes into an active state (i.e. a door contact being opened), the circuit path has been altered and it must now pass through a second resistor wired in series with the first. This gives a reading of 4K ohms and will trigger an intruder alarm. If a resistance reading is not recognised by the system either due to short-circuit or open-circuit, an anti-tamper alarm will trigger.

Dual loop is more commonly known as Balanced EOL (End of Line) resistors. It is more secure than the former Double Pole loop, but nevertheless can be bypassed by someone with sufficient knowledge of security alarm systems.

Superstatistics. Superstatistics is a branch of statistical mechanics or statistical physics devoted to the study of non-linear and non-equilibrium systems. It is characterized by using the superposition of multiple differing statistical models to achieve the desired non-linearity. In terms of ordinary statistical ideas, this is equivalent to compounding the distributions of random variables and it may be considered a simple case of a doubly stochastic model.

Consider an extended thermodynamical system which is locally in equilibrium and has a Boltzmann distribution, that is the probability of finding the system in a state with energy  is proportional to . Here  is the local inverse temperature. A non-equilibrium thermodynamical system is modeled by considering macroscopic fluctuations of the local inverse temperature. These fluctuations happen on time scales which are much larger than the microscopic relaxation times to the Boltzmann distribution. If the fluctuations of  are characterized by a distribution , the superstatistical Boltzmann factor of the system is given by

This defines the superstatistical partition function

for system that can assume discrete energy states . The probability of finding the system in state  is then given by

Modeling the fluctuations of  leads to a description in terms of statistics of Boltzmann statistics, or "superstatistics". For example, if  follows a Gamma distribution, the resulting superstatistics corresponds to Tsallis statistics. Superstatistics can also lead to other statistics such as power-law distributions or stretched exponentials. One needs to note here that the word super here is short for superposition of the statistics.

This branch is highly related to the exponential family and Mixing. These concepts are used in many approximation approaches, like particle filtering (where the distribution is approximated by delta functions) for example.
