Social Trap
In psychology, a social trap is a conflict of interest or perverse incentive where individuals or a group of people act to obtain short-term individual gains, which in the long run leads to a loss for the group as a whole. Social traps are the cause of countless environmental issues, including overfishing, energy "brownout" and "blackout" power outages during periods of extreme temperatures, the overgrazing of cattle on the Sahelian Desert, the destruction of the rainforest by logging interests and agriculture, and, most importantly, climate change.

Suzuki TT Superbikes: Real Road Racing Championship
Suzuki TT Superbikes: Real Road Racing, often shortened to simply Suzuki TT Superbikes; also known as TT Superbikes: Real Road Racing in Europe and Japan, is a 2005 motorcycle simulation racing video game developed by Jester Interactive exclusively for the PlayStation 2 gaming console. The game was self–published by Jester in Europe, with Valcon Games and Taito handling publishing in North America and Japan, respectively. In North America, the game is licensed under Suzuki, an automobile manufacturer. The title features over 50 licensed vehicles and is entirely based around the famed Isle of Man TT race, a 60.72 km annual competition held within the Isle of Man. It is the second game based on the race, following the 1995 release of Manx TT Super Bike, though this game was only based on the Manx TT event, which is a small section of the course. The game was available on the PlayStation 3 via the North American PlayStation Store. Suzuki TT Superbikes has since received two sequels.

Base 16 Floating Point
IBM System/360 computers, and subsequent machines based on that architecture (mainframes), support a hexadecimal floating-point format (HFP). In comparison to IEEE 754 floating-point, the IBM floating-point format has a longer significand, and a shorter exponent. All IBM floating-point formats have 7 bits of exponent with a bias of 64. The normalized range of representable numbers is from 16−65 to 1663 (approx. 5.39761 × 10−79 to 7.237005 × 1075). The number is represented as the following formula: (−1)sign × 0.significand × 16exponent−64.

Hungarian Testing Board
The Hungarian Testing Board (HTB), or the Hungarian Software Testing and Qualifications Board (HSTQB), is a non-profit organisation founded in 2007 for the purpose of supporting the improvement of the professionals practicing in the field of inland software testing, software quality and related areas. In addition to testing in itself, the HTB is an official panel for all testing related disciplines and activities in Hungary. HTB is the only official member organisation of ISTQB (International Software Testing and Qualification Board) in Hungary, therefore the organiser, provider of the ISTQB Tester Certification exams based on international standards. In addition to arranging exams for professionals and providing standards, in 2011 HTB created HUSTEF (Hungarian Software Testing Forum), which is the biggest software testing conference in the Central European Region. The Board consists of testing experts from a wide range of organizations: the IT industry, consultancies, training providers and other professional and scientific/academic communities who volunteer their time to the achievement of organization's goals.

Mobile Agents in the Medical Care Domain
A mobile agent is a software application that moves naturally among hosts in a uniform and non-uniform environment; it starts with one host and then moves onto the next in order to divide data between clients. The mobile paradigm is utilized in a wide assortment of medical care applications such as the medical information of a patient, the recovery of clinical information, the incorporation of information pertaining to their wellbeing, dynamic help, telemedicine, obtaining clinical data, patient administration, and so on. The accompanying security issues have grown in tandem with the complexity and improvements in mobile agent technologies. As mobile agents work in an insecure environment, their security is a top priority when communicating and exchanging data and information. Data integrity, data confidentiality and authentication, on-repudiation, denial of service, and access control, are all key security concerns with mobile agent migration.

Test Generation
Test generation is the process of creating a set of test data or test cases for testing the adequacy of new or revised software applications. Test Generation is seen to be a complex problem and though a lot of solutions have come forth most of them are limited to toy programs. Test Generation is one aspect of software testing. Since testing is labor-intensive, accounting for nearly one third of the cost of the system development, the problem of generating quality test data quickly, efficiently and accurately is seen to be important.

Epiphany (Feeling)
An epiphany (from the ancient Greek ἐπιφάνεια, epiphanea, "manifestation, striking appearance") is an experience of a sudden and striking realization. Generally the term is used to describe scientific breakthrough, religious or philosophical discoveries, but it can apply in any situation in which an enlightening realization allows a problem or situation to be understood from a new and deeper perspective. Epiphanies are studied by psychologists and other scholars, particularly those attempting to study the process of innovation. Epiphanies are relatively rare occurrences and generally follow a process of significant thought about a problem. Often they are triggered by a new and key piece of information, but importantly, a depth of prior knowledge is required to allow the leap of understanding. Famous epiphanies include Archimedes's discovery of a method to determine the volume of an irregular object ("Eureka!") and Isaac Newton's realization that a falling apple and the orbiting moon are both pulled by the same force.
