CG: n CT: A public-key algorithm (also known as an asymmetric algorithm) is one where the keys used for encryption and decryption are different, and the decryption key cannot be calculated from the encryption key. This allows someone to keep a public-key/private-key pair. S: ScDir – shorturl.at/uCUW4 (last access: 31 December
GC: n CT: Exploring the nature of the atom. Uranium was discovered in 1789 by Martin Klaproth, a German chemist, and named after the planet Uranus. Ionising radiation was discovered by Wilhelm Rontgen in 1895, by passing an electric current through an evacuated glass tube and producing continuous X-rays. Then
GC: n CT: ‘Attractors‘ are all-or-none states abstracted from dynamic trajectories. Each attractor can represent a symbol. A symbol is present when the phase-space trajectory belongs to the corresponding attractor. There are as many symbols as ‘attraction basins‘. No symbol is instantiated in a state characterized by a ‘chaotic attractor‘.
GC: n CT: Reasoning is the ability to make inferences, and automated reasoning is concerned with the building of computing systems that automate this process. Although the overall goal is to mechanize different forms of reasoning, the term has largely been identified with valid deductive reasoning as practiced in mathematics
GC: n CT: In order to better answer the current needs of training in automatic control engineering in higher education, Scilab joined forces with Didalab, the French specialist of the educational equipment. This association gave birth to D_Scil, ideal tool to teach automatic engineering. The pedagogical purpose of D_Scil is
GC: n CT: Automatic Control Systems provides engineers with a fresh new controls book that places special emphasis on mechatronics. It follows a revolutionary approach by actually including a physical lab. In addition, readers will find authoritative coverage of modern design tools and examples. Current mechatronics applications build motivation to
GC: n CT: Automatic Natural Language Processing and the Detection of Reading Skills and Reading Comprehension. The primary goal of this study is to assess two approaches for detecting comprehension processes in R-SAT (Reading Strategy Assessment Tool). One approach is based on Latent Semantic Analysis (LSA) while the other is
GC: n CT: Automatic speech recognition (ASR) can be defined as the independent, computer-driven transcription of spoken language into readable text in real time (Stuckless, 1994). In a nutshell, ASR is technology that allows a computer to identify the words that a person speaks into a microphone or telephone and
GC: n CT: Automation is the creation of technology and its application in order to control and monitor the production and delivery of various goods and services. It performs tasks that were previously performed by humans. Automation is being used in a number of areas such as manufacturing, transport, utilities,
GC: n CT: Leonardo Da Vinci wrote extensively about automatons, and his personal notebooks are littered with ideas for mechanical creations ranging from a hydraulic water clock to a robotic lion. Perhaps most extraordinary of all is his plan for an artificial man in the form of an armored Germanic
GC: n CT: One major area of autonomous vehicle development concerns an area where machines have already been used for over a century – the motor car. Cars are so widely used that there is already a coherent system in place to organise their operation, perhaps making it easier to
GC: n CT: Autotrophs vs. Heterotrophs. Living organisms obtain chemical energy in one of two ways. Autotrophs, shown in Figure below, store chemical energy in carbohydrate food molecules they build themselves. Food is chemical energy stored in organic molecules. Food provides both the energy to do work and the carbon
CG: n CT: An instant messaging user may be represented in communications with other users by an avatar that is capable of being animated or may convey information about the user by displaying other types of self-expression items, such as non-animated icons, sounds, wallpaper, or objects associated with an avatar or
CG: n CT: The azimuth angle is the compass direction from which the sunlight is coming. At solar noon, the sun is always directly south in the northern hemisphere and directly north in the southern hemisphere. The azimuth angle varies throughout the day as shown in the animation below. S:
GC: n CT: Banking Energy. The fact that electrical energy must be used in real time, when it’s generated, creates a host of problems. Geothermal plants produce electricity around the clock and need a way to save the electricity they produce at night for more productive times of day. Wind
GC: n CT: A conversational agent is a software program which interprets and responds to statements made by users in ordinary natural language. It integrates computational linguistics techniques with communication over the internet. S: Chatbots.org – https://www.chatbots.org/conversational_agent/ (last access: 30 December 2014) N: 1. conversational (adj): 1779, from conversation (mid-14c.,
GC: n CT: What is e-learning? In the early days of e-learning, some people were concerned that bringing computers into the classroom would remove the human element that many learners benefit from. But technology has developed, and smartphones and tablets are now widely embraced in both the classroom and office.
GC: n CT: A genetic algorithm is a search heuristic that is inspired by Charles Darwin’s theory of natural evolution. This algorithm reflects the process of natural selection where the fittest individuals are selected for reproduction in order to produce offspring of the next generation. The process of natural selection
GC: n CT: The concept of green and blue water is relatively new1. When precipitation reaches land, it takes either green or blue water pathways. The water that is stored in the unsaturated soil layer forms the green water resource and the water that is stored in the rivers, streams,
GC: n CT: An intelligent agent is a software that assists people and act on their behalf. Intelligent agents work by allowing people to delegate work that they could have done, to the agent software. Agents can perform repetitive tasks, remember things you fo rgot, intelligently summarize complex data, learn
GC: n CT: Machine learning is the science of getting computers to act without being explicitly programmed. In the past decade, machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome. Machine learning is so pervasive today that
GC: n CT: Many reports have emphasized the need for major changes to the agricultural system to meet the challenge of feeding the growing population while minimizing environmental impacts (Godfray et al., 2010; Foley et al., 2011). Organic farming, which largely relies on organic materials instead of chemical fertilizers, pesticides,
