Matheuristics. Matheuristics are problem agnostic optimization algorithms that make use of mathematical programming (MP) techniques in order to obtain heuristic solutions. Problem-dependent elements are included only within the lower-level mathematic programming, local search or constructive components. An essential feature is the exploitation in some part of the algorithms of features derived from the mathematical model of the problems of interest, thus the definition "model-based heuristics" appearing in the title of some events of the conference series dedicated to matheuristics matheuristics web page.

The topic has attracted the interest of a community of researchers, and this led to the publication of dedicated volumes and journal special issues besides to dedicated tracks and sessions on wider scope conferences.

A word of caution is needed before delving into the subject, because obviously the use of MP for solving optimization problems, albeit in a heuristic way, is much older and much more widespread than matheuristics. However, this is not the case for metaheuristics. Even the very idea of designing MP methods specifically for heuristic solution has innovative traits, when opposed to exact methods which turn into heuristics when enough computational resources are not available.

Some approaches using MP combined with metaheuristics have begun to appear regularly in the matheuristics literature. This combination can go two-ways, both in MP used to improve or design metaheuristics and in metaheuristics used for improving known MP techniques, even though the first of these two directions is by far more studied.

Lufkin (brand). Lufkin is a brand featuring primarily measurement tools such as calipers, gauges, micrometers, and measuring tapes. Lufkin is a brand of Apex Tool Group.

History

The company was founded by Edward Taylor Lufkin, an American Civil War veteran of the Sixtieth Regiment Ohio Volunteer Infantry in Cleveland, Ohio, 1869 and was originally named E.T. Lufkin Board and Log Rule Manufacturing Company.  Its Canadian manufacturing plant was first at Windsor, Ontario around 1907 and later at Barrie, Ontario around 1948 . The company's headquarters and chief U.S. manufacturing plant later moved to Saginaw, Michigan, and remained there for decades.

The company was acquired in 1967 by Cooper Industries, which aimed to create a stable of hand tools brands through acquisitions. The Saginaw plant was soon closed and a new plant in Apex, North Carolina became the chief U.S. manufacturing plant.  

The brand was a member of the Cooper Tools group until that group was sold off to form Apex Tool Group in 2012 and Cooper Industries was acquired by Eaton Corporation.

Innovations

Throughout its history Lufkin patented a variety of devices and manufacturing processes.

SZD-11 Albatros. The SZD-11 Albatros was a single-seat glider aircraft that was designed and built in Poland at Szybowcowy Zakład Doświadczalny - Glider Experimental Works in Bielsko-Biała in 1954. Only one prototype was completed and flown.

Development
Based on a fuselage of the SZD-8 Jaskółka, the SZD-11 Albatros was designed to investigate the performance of aircraft during flight in thermal lift. The main designer was Justyn Sandauer, and the main constructor was J. Niespał. With wings of greater span, and reduced empty weight, the wing loading was reduced, markedly improving the climb performance over the 16m-span SZD-8 Jaskółka. Three more SZD-11 aircraft were planned with fixed trailing edges and no flaps, but only the prototype was completed. The SZD-11 first flew on 14 September 1954, flown by Tadeusz Góra.

ISO 19439. ISO 19439:2006 Enterprise integration—Framework for enterprise modelling, is an international standard for enterprise modelling and enterprise integration developed by the International Organization for Standardization, based on CIMOSA and GERAM.

Overview 
ISO 19439 framework wants to provide a "unified conceptual basis for model-based enterprise engineering that enables consistency, convergence and interoperability of the various modelling methodologies and supporting tools. The framework does not encompass methodological processes; it is neutral in this regard".

This standard specifies a framework, which "serves as a common basis to identify and coordinate standards development for modelling of enterprises, but not restricted to, computer integrated manufacturing. It also serves as the basis for further standards for the development of models that will be computer-enactable and enable business process model-based decision support leading to model-based operation, monitoring and control".

Dimensions 
According to David Shorter (2004) the ISO19439 is alike CIMOSA, and has defines three dimensions for enterprise modelling:

 Model phase : "The enterprise model phases are based on the idea that enterprise models have a life cycle that is related to the life cycle of the entity being modeled. The phases defined in the standard are: Domain Identification, Concept Definition, Requirements Definition, Design Specification, Implementation Description, Domain Operation, Decommission Definition."    
 View dimension : "This is based on the idea that both enterprise modelers and users filter their observations of the real world by particular views. The predefined views are: Function View, Information View, Resource View, Organization View/Decision View." 
 Genericity dimension: "This defines the dimension from general concepts to particular models . The standard defines three levels of genericity: Generic Level, Partial Level, Particular Level"

SZD-12 Mucha 100. The SZD-12 Mucha 100 (Szybowcowy Zakład Doświadczalny - Glider Experimental Works) was a single-seat glider aircraft that was designed and built in Poland from 1953.

Development
The SZD-12 Mucha (Fly) 100 was derived from the IS-2 Mucha-ter for use by aero clubs throughout Poland. Two hundred and ninety were built with 73 exported to several countries and an unknown number were licence-built in the People's Republic of China (PRC).

Constructed from wood/plywood throughout, the Mucha 100 was much improved from the IS-2 Mucha, with smoother surfaces, better aerodynamics and comprehensive instruments and equipment including a KF-18 oxygen system, lighting and instruments for cloud flying. Pilot comfort was improved by slightly reclining the seat back and increasing legroom, and visibility was increased through a larger one-piece cockpit canopy. Schempp-Hirth style airbrakes replaced the DFS style airbrakes of the IS-2, external mass balances fitted to the ailerons cured the tendency to flutter. The wing incidence was reduced to 2° to better align the fuselage with the airflow at higher speeds, reducing drag. Main designer was Władysław Okarmus, constructors were Jan Dyrek and Zbigniew Badura. The prototype was made in ZSLS No.5 in Krosno - it was the only prototype of SZD design that was not made in the SZD works in Bielsko.

Flight trials commenced on 14 November 1953 in Krosno (first flight by Adam Zientek); a tendency to control surface flutter was resolved by mass balancing. After this and other improvements, the Mucha 100 was cleared for production as the SZD-12 Mucha 100. From 1954, 256 were built in ZSLS in Krosno, 14 in Gdańsk and 20 in Wrocław.

Further improvements were incorporated into the SZD-12A Mucha 100A, which had the external mass balances replaced by weights in the leading edges of the ailerons, forward of the hinges. Another modification which was also applied retrospectively to earlier units was a re-located mainwheel, moved rearwards to reduce the weight on the tailwheel during ground handling.

70 Mucha 100's were exported, mostly to the USSR, DDR, Italy, Switzerland and China in multiple orders; single examples were also exported to Austria, France, Finland and India.

Variants
SZD-12 Mucha 100 – initial production version, 104 built
SZD-12A Mucha 100A – modified version with altered undercarriage arrangement and internal aileron mass balances, 186 built from 1958

Agilent ChemStation. Agilent ChemStation is a software package to control Agilent liquid chromatography, gas chromatography, and  ultraviolet-visible spectroscopy  systems such as the 1050, 1100 and 1200 Series HPLC system and the 8453 and 8454 single-beam diode array detector spectrophotometers. It is an evolution of the Hewlett-Packard ChemStation System.

Two versions are available: one ("online") in connection with the modules of the HPLC chain is designed to control instruments and run experiments, and the other ("offline"), without a connection with the HPLC chain, is designed to analyze data.

ChemStation is structured around a number of registers.  Two of the more important registers are CHROMREG and CHROMRES, the chromatographic data registers. Other special registers exist for the UV-vis implementation of the software.

ChemStation has a command line interpreter and can run macros. Those macros are files grouping a set of commands.  These files possess a .mac extension.

ChemStation can import analysis lists and export result files in XML by adding new lines to the ChemStation.ini configuration file. This is a feature to implement the connection with a Laboratory information management system (LIMS).

Global IP Solutions. Global IP Solutions (also known as GIPS) was a United States–based corporation that developed real-time voice and video processing software for IP networks, before it was acquired by Google in May 2010. The company delivered embedded software that enabled real-time communications capabilities for video and voice over IP (VoIP). GIPS was perhaps best known for developing the narrowband iLBC and wideband iSAC speech codecs.

GIPS software was generally delivered as “engines” that packaged together voice and video processing components for smoother integration and better performance. GIPS’ customers are primarily service providers, application developers, and manufacturers of IP phones, gateways or voice and video conferencing systems.

History
The company (formerly known as Global IP Sound) was founded in July 1999 in Stockholm, Sweden, by signal processing experts Roar Hagen (then GIPS’ CTO)  and Bastiaan Kleijn (then GIPS’ Chief Scientist), Espen Fjogstad and Ivar T. Hognestad. The founders recognized that, at the time, most VoIP technology had been developed for circuit switched networks, and were therefore not suited to handle the network delay, jitter and packet loss presented by IP networks.

In May 2010, Google bought GIPS for $68.2 million. In June 2011, Google released WebRTC, a proposed standard for pluginless peer-to-peer audiovisual communication between browsers, with GIPS technology.

Charles Kohlhase. Charles Kohlhase (born 1935) worked for forty years at NASA/JPL leading the design of several robotic deep-space planetary missions. He is also an author, game developer and lecturer.

Early life 
Kohlhase graduated with honors from The McCallie School in Chattanooga, Tennessee in 1953, with honors for a BS degree in Physics from the Georgia Institute of Technology in 1957, and with a Masters of Engineering degree from UCLA in 1968. He served as a LTJG on the US Navy aircraft carriers Essex and Independence from 1957–1959 as the assistant electrical officer of a nuclear weapons team.

Work at the NASA Jet Propulsion Laboratory 
Kohlhase led the design of many deep-space missions during his extended career, including Mariner, Viking, Voyager, and Cassini missions. For his sustained robotic exploration contributions over the last 40 years of the 20th century and solid success record, he received the NASA Distinguished Service Medal and has an asteroid, 13801 Kohlhase, named in his honor. The official  was published by the Minor Planet Center on January 6, 2003 (). He managed and guided the team which designed the epic Voyager Grand Tour mission to the outer planets and their moons and rings. After Voyager, Kohlhase became the science and mission design manager for the international Cassini–Huygens mission to Saturn and Titan. Following the launch, cruise, and Saturn orbit phases of Cassini, he has continued to advise NASA/JPL on numerous missions to Mars and to other worlds. In addition to his counsel on various review boards, Kohlhase has chaired the Mars Program Systems Engineering Team, composed of many senior experts spanning diverse disciplines. He is also a member of the Advisory Council for The Planetary Society.

He partnered with Jim Blinn in creating computer graphic animations of the Voyager spacecraft encounters and for the Carl Sagan Cosmos TV series. He has directed many public activities that creatively blend art, science, and education, including international projects sponsored by the NEA, NASA, Dept of Education, and other agencies.

Kohlhase was also a member of Voyager team honored with an Emmy for ""The Farthest" (2017)," by the National Academy of Television Arts & Sciences at their 39th Annual News & Documentary Emmy Awards in New York, N.Y., on October 1, 2018

Root barrier. A root barrier is an underground wall placed to block plant roots. This is often for the purpose of protecting structures or other plants, but root barriers are also used to preserve soil moisture.

Development
Root barriers were developed to stop trees damaging buildings. Concrete was historically a common material but since 1992 plastic root barriers have become more common due to their resistance to cracking caused by soil and moisture movement.

Placement 
Root barriers intended to protect structures normally run parallel to the structure at a distance. They typically extend down to a naturally-occurring soil layer which is not penetrable by roots, to prevent the roots growing under the barrier. To avoid endangering trees, root barriers must be placed some distance away from the tree and avoid surrounding it completely.

Applications
Root barriers can be used to protect infrastructure from damage by tree roots below. They are also moisture-proof, which can be useful to preserve buildings on clay soils by preventing moisture escaping laterally. After installation the soil under the building can be rehydrated if necessary.

Root barriers are also used to separate plant roots from each other. In particular, walnut trees secrete the chemical juglone which is toxic to other plants but the use of root barriers can prevent the yield reduction that would normally occur when walnut trees are alley cropped with maize as often occurs in the American Midwest.

HP 110. The HP 110 (aka HP Portable and HP 45710A) is an MS-DOS-compatible laptop released in 1984 by Hewlett-Packard. It runs off batteries and uses a Harris 80C86 running at 5.33 MHz with  of RAM. It has an 80 character by 16 line monochrome () liquid crystal display, runs MS-DOS 2.11 in ROM, and has the application programs MemoMaker, Terminal Emulator and Lotus 1-2-3 in ROM.

The LCD can be tilted for visibility, and can be folded down over the keyboard for transport, unlike computers such as the TRS-80 Model 100 which has the display in the same fixed plane as the keyboard. The HP 110 is similar to the Dulmont Magnum and the Sharp PC-5000, but all three computers were separately developed by their respective companies. At introduction it had a list price of  .

HP 110 Plus
In 1985 the HP 110 Plus (aka HP Portable Plus and HP 45711A) was released with a higher-speed internal modem (1200 baud vs. 300 baud), more resident applications, reduced price, and an 80 character by 25 line display, which improved compatibility with desktop software applications. In text mode, the machine supported either a derivation of the 1984 version of the HP Roman-8 character set (in "HP mode") or IBM code page 437 (in "ALT mode").

Reception
BYTE in January 1985 acknowledged the HP 110's high price, but stated that it was "a computer with true desktop capability and performance well worth its cost for those who need the power". It praised the keyboard, and predicted that the built-in Lotus 1-2-3 "will likely account for more HP 110 sales than any other single feature".

Creative Computing said that the 110 was "the overwhelming winner" in the category of notebook portables when "price is no object" for 1984. The magazine stated that the $2995 price was "surprising modest" for its hardware, Lotus 1-2-3 and other software, and excellent manufacturer support.
