2D Filters
Two dimensional filters have seen substantial development effort due to their importance and high applicability across several domains. In the 2-D case the situation is quite different from the 1-D case, because the multi-dimensional polynomials cannot in general be factored. This means that an arbitrary transfer function cannot generally be manipulated into a form required by a particular implementation. The input-output relationship of a 2-D IIR filter obeys a constant-coefficient linear partial difference equation from which the value of an output sample can be computed using the input samples and previously computed output samples. Because the values of the output samples are fed back, the 2-D filter, like its 1-D counterpart, can be unstable.

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.

Acute and Obtuse Triangles
An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle. Acute and obtuse triangles are the two different types of oblique triangles — triangles that are not right triangles because they have no 90° angle.

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.

Signalling (Economics)
In contract theory, signalling (or signaling; see spelling differences) is the idea that one party (the agent) credibly conveys some information about itself to another party (the principal). Although signalling theory was initially developed by Michael Spence based on observed knowledge gaps between organisations and prospective employees, its intuitive nature led it to be adapted to many other domains, such as Human Resource Management, business, and financial markets. In Spence's job-market signaling model, (potential) employees send a signal about their ability level to the employer by acquiring education credentials. The informational value of the credential comes from the fact that the employer believes the credential is positively correlated with having the greater ability and difficulty for low ability employees to obtain. Thus the credential enables the employer to reliably distinguish low ability workers from high ability workers. The concept of signaling is also applicable in competitive altruistic interaction, where the capacity of the receiving party is limited.

Vibrotactile Feedback in Virtual Reality
While substantial progress in computer graphics and sound rendering has resulted in highly realistic visual and auditory experiences in virtual reality (VR), achieving genuine immersion, interactivity, and the stimulation of imagination necessitates the integration of realistic tactile experiences, often facilitated through haptic feedback. The incorporation of vibrotactile feedback in VR allows users to fully engage their sense of touch, enabling them to explore, grasp, and manipulate virtual objects as if they were interacting with them in the physical world.

Life Quality Index
The Life Quality Index (LQI) is a calibrated compound social indicator of human welfare that reflects the expected length of life in good health and enhancement of the quality of life through access to income. The Life Quality Index combines two primary social indicators: the expectancy of healthy life at birth, E, and the real gross domestic product per person, G, corrected for purchasing power parity as appropriate. Both are widely available and accurate statistics.

NS320xx
The NS32000, sometimes known as the 32k, is a series of microprocessors produced by National Semiconductor. The first member of the family, the 32016, came to market in 1982, making it the first 32-bit general-purpose microprocessor on the market. However, the 32016 contained a large number of bugs and often could not be run at its rated speed. These problems, and the presence of the similar Motorola 68000, led to almost no use in the market. Several improved versions followed, including 1985's 32032 which was essentially a bug-fixed 32016 with an external 32-bit data bus possible due to improvements in chip carriers that were becoming common in the market. However, it offered only about 50% better speed than the 32016, and was outperformed by the 32-bit Motorola 68020, released a year prior. The 32532, released in 1987, outperformed the competing Motorola 68030 by almost two times, but by this time most interest in microprocessors had turned to RISC platforms and this otherwise excellent design saw almost no use as well. National was working on further improvements in the 32732, but eventually gave up attempting to compete in the central processing unit (CPU) space. Instead, the basic 32000 architecture was combined with several support systems and relaunched as the Swordfish microcontroller. This had some success in the market before it was replaced by the CompactRISC architecture in mid-1990s.

GNU Build System
The GNU Build System, also known as the Autotools, is a suite of programming tools designed to assist in making source code packages portable to many Unix-like systems. It can be difficult to make a software program portable: the C compiler differs from system to system; certain library functions are missing on some systems; header files may have different names. One way to handle this is to write conditional code, with code blocks selected by means of preprocessor directives (#ifdef); but because of the wide variety of build environments this approach quickly becomes unmanageable. Autotools is designed to address this problem more manageably. Autotools is part of the GNU toolchain and is widely used in many free software and open source packages. Its component tools are free software-licensed under the GNU General Public License with special license exceptions permitting its use with proprietary software. The GNU Build System makes it possible to build many programs using a two-step process: configure followed by make.

Gamification and Technology Acceptance
Technology acceptance is essential for technology success. Individual users are known to differ in their tendency to adopt and interact with new technologies. Among the individual differences, personality has been shown to be a predictor of users’ beliefs about technology acceptance. Gamification, on the other hand, has been shown to be a good solution to improve students’ motivation and engagement while learning. Despite the growing interest in gamification, less research attention has been paid to the effect of personality, specifically based on the Five Factor model (FFM), on gamification acceptance in learning environments.

ID-Based Encryption
ID-based encryption, or identity-based encryption (IBE), is an important primitive of ID-based cryptography. As such it is a type of public-key encryption in which the public key of a user is some unique information about the identity of the user (e.g. a user's email address). This means that a sender who has access to the public parameters of the system can encrypt a message using e.g. the text-value of the receiver's name or email address as a key. The receiver obtains its decryption key from a central authority, which needs to be trusted as it generates secret keys for every user. ID-based encryption was proposed by Adi Shamir in 1984. He was however only able to give an instantiation of identity-based signatures. Identity-based encryption remained an open problem for many years. The pairing-based Boneh–Franklin scheme and Cocks's encryption scheme based on quadratic residues both solved the IBE problem in 2001.

Iterared Skew Polynomial Rings
Skew polynomial rings used to be, especially during the 1970’s and 1980’s, a popular topic of the modern abstract Algebra with great theoretical interest. The researchers’ attention about them has renewed recently, due to the important applications that they have found to the study of Quantum Groups and to Cryptography. The present work studies a special class of iterated skew polynomial rings over a ring R, defined with respect to a finite set of pairwise commuting derivations of R.

Local Zeta-Function
In number theory, the local zeta function Z(V, s) (sometimes called the congruent zeta function) is defined as where Nm is the number of points of V defined over the mth cyclotomic field extension Fqm of Fq, and V is a non-singular n-dimensional projective algebraic variety over the field Fq with q elements. By the variable transformation u = q−s, then it is defined by as the formal power series of the variable [math]\displaystyle{ u }[/math]. Equivalently, the local zeta function sometimes is defined as follows: In other word, the local zeta function Z(V, u) with coefficients in the finite field Fq is defined as a function whose logarithmic derivative generates the numbers Nm of the solutions of equation, defining V, in the m degree extension Fqm.
