Convolution (Computer Science)
In computer science, specifically formal languages, convolution (sometimes referred to as zip) is a function which maps a tuple of sequences into a sequence of tuples. This name zip derives from the action of a zipper in that it interleaves two formerly disjoint sequences. The reverse function is unzip which performs a deconvolution.

Positional Tracking
Positional tracking detects the precise position of the head-mounted displays, controllers, other objects or body parts within Euclidean space. Positional tracking registers the exact position due to recognition of the rotation (pitch, yaw and roll) and recording of the translational movements. Since virtual reality is about emulating and altering reality it's important that we can track accurately how objects (like the head or the hands) move in real life in order to represent them inside VR. Defining the position and orientation of a real object in space is determined with the help of special sensors or markers. Sensors record the signal from the real object when it moves or is moved and transmit the received information to the computer.

Virtual Reality in the Rehabilitation
Over the past two decades, virtual reality technology (VRT)-based rehabilitation has been increasingly examined and applied to assist patient recovery in the physical and cognitive domains. The advantages of the use of VRT in the neurorehabilitation field consist of the possibility of training an impaired function as a way to stimulate neuron reorganization (to maximize motor learning and neuroplasticity) and restoring and regaining functions and abilities by interacting with a safe and nonthreatening yet realistic virtual reality environment (VRE). Furthermore, VREs can be tailored to patient needs and provide personalized feedback on performance. VREs may also support cognitive training and increases patient motivation and enjoyment. Despite these potential advantages, there are inconclusive data about the usefulness of VRT in neurorehabilitation settings, and some issues on feasibility and safety remain to be ascertained for some neurological populations.

Forensic Arts
Forensic art is any art used in law enforcement or legal proceedings. Forensic art is used to assist law enforcement with the visual aspects of a case, often using witness descriptions and video footage. It is a highly specialized field that covers a wide range of artistic skills, such as composite drawing, crime scene sketching, image modification and identification, courtroom drawings, demonstrative evidence, and postmortem and facial approximation aids. It is rare for a forensic artist to specialize in more than one of these skills. Many forensic artists do the job as a collateral duty to their "regular" job in law enforcement, such as police officer, crime scene tech, etc. Such forensic artists perform their work while on a fixed salary and are not additionally compensated for artistic duties. There are few full-time forensic artist jobs available. Most full-time artists work in large cities, or in state or federal agencies. "Freelancing" in forensic art is a difficult career path, as ties to law enforcement are a necessary part of the job, and agencies have limited budgets to pay outside contractors. The skill of facial approximation is closely associated and related to forensic anthropology in that an artist specializes in the reconstruction of the remains of a human body. Generally this discipline focuses on the human face for identification purposes. The forensic artist can create a facial approximation in a number of ways to include 2D (drawings), 3D (sculptures) and other methods using new computer technology. Forensic artists generally can add greater character and make their subjects come back to "life".

Office 365
Office 365 is a line of subscription services offered by Microsoft as part of the Microsoft Office product line. The brand encompasses plans that allow use of the Microsoft Office software suite over the life of the subscription, as well as cloud-based software-as-a-service products for business environments, such as hosted Exchange Server, Skype for Business Server, and SharePoint, among others. All Office 365 plans include automatic updates to their respective software at no additional charge, as opposed to conventional licenses for these programs—where new versions require purchase of a new license. After a beta test that began in October 2010, Microsoft launched Office 365 on 28 June 2011, aimed originally at corporate users as a successor to Microsoft Business Productivity Online Suite (BPOS). With the release of Microsoft Office 2013, Microsoft expanded Office 365 to include new plans aimed at different types of businesses, along with new plans aimed at general consumers, including benefits tailored towards Microsoft consumer services such as OneDrive (whose integration with Office was a major feature of the 2013 suite). On 21 April 2020, the consumer and small business plans of Office 365 were renamed Microsoft 365, which emphasizes productivity features and services outside of the core Microsoft Office software suite. All products that were called Office 365 were renamed as Microsoft 365 on the same day. In the fourth quarter of fiscal year 2017, Office 365 revenue exceeded that of conventional license sales of Microsoft Office software for the first time.

Crackdown
Crackdown is a series of action-adventure video games created by David Jones and published by Xbox Game Studios. The series takes place in a futuristic dystopian city controlled and enforced by a secret organization called the Agency. The games center on the Agency's super soldiers, known as 'Agents', as they fight threats ranging from various criminal syndicates, a terrorist group known as 'Cell', and zombie-like monsters called 'Freaks'. Games of the series have been developed by various game developers, with the first game Crackdown completed by Realtime Worlds on February 20, 2007, and a sequel called Crackdown 2 developed by Ruffian Games on July 6, 2010. Both games were released for the Xbox 360. A third installment Crackdown 3 developed by Sumo Digital was released on February 15, 2019 for Xbox One and Microsoft Windows. Although Crackdown started as a game that was released with access codes for the Halo 3 multiplayer beta, the game itself has been met with positive critical reception and won several video game awards. Critics praised the sandbox style third-person shooter for allowing the ability to cause massive destruction in a non-linear gameplay, while also criticizing the series for lacking an actual story. The series has garnered mostly positive reception and commercial success.

Altitude (Triangle)
In geometry, an altitude of a triangle is a line segment through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex). This line containing the opposite side is called the extended base of the altitude. The intersection of the extended base and the altitude is called the foot of the altitude. The length of the altitude, often simply called "the altitude", is the distance between the extended base and the vertex. The process of drawing the altitude from the vertex to the foot is known as dropping the altitude at that vertex. It is a special case of orthogonal projection. Altitudes can be used in the computation of the area of a triangle: one half of the product of an altitude's length and its base's length equals the triangle's area. Thus, the longest altitude is perpendicular to the shortest side of the triangle. The altitudes are also related to the sides of the triangle through the trigonometric functions. In an isosceles triangle (a triangle with two congruent sides), the altitude having the incongruent side as its base will have the midpoint of that side as its foot. Also the altitude having the incongruent side as its base will be the angle bisector of the vertex angle. It is common to mark the altitude with the letter h (as in height), often subscripted with the name of the side the altitude is drawn to. In a right triangle, the altitude drawn to the hypotenuse c divides the hypotenuse into two segments of lengths p and q. If we denote the length of the altitude by hc, we then have the relation For acute and right triangles the feet of the altitudes all fall on the triangle's sides (not extended). In an obtuse triangle (one with an obtuse angle), the foot of the altitude to the obtuse-angled vertex falls in the interior of the opposite side, but the feet of the altitudes to the acute-angled vertices fall on the opposite extended side, exterior to the triangle. This is illustrated in the adjacent diagram: in this obtuse triangle, an altitude dropped perpendicularly from the top vertex, which has an acute angle, intersects the extended horizontal side outside the triangle.

Aural Cascading Style Sheets
Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language like HTML. CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript. CSS is designed to enable the separation of presentation and content, including layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file, and reduce complexity and repetition in the structural content. Separation of formatting and content also makes it feasible to present the same markup page in different styles for different rendering methods, such as on-screen, in print, by voice (via speech-based browser or screen reader), and on Braille-based tactile devices. CSS also has rules for alternate formatting if the content is accessed on a mobile device. The name cascading comes from the specified priority scheme to determine which style rule applies if more than one rule matches a particular element. This cascading priority scheme is predictable. The CSS specifications are maintained by the World Wide Web Consortium (W3C). Internet media type (MIME type) text/css is registered for use with CSS by RFC 2318 (March 1998). The W3C operates a free CSS validation service for CSS documents. In addition to HTML, other markup languages support the use of CSS including XHTML, plain XML, SVG, and XUL.

Map Database Management
Map database management systems are software programs designed to efficiently store and recall spatial information. They are widely used in localization and navigation, especially in automotive applications. Moreover, they are playing an increasingly important role in the emerging areas of location-based services, active safety functions and advanced driver-assistance systems. Common to these functions is the requirement for an on-board map database that contains information describing the road network. When designed well, a map database enables the rapid indexing and lookup of a large amount of geographic data.
