NL-addressing is approach for building of a kind of so called “post-relational databases”. Some practical aspects of implementation and using of NL-addressing are discussed in this paper. The software realized in this research was practically tested as a part of an instrumental system for automated construction of ontologies "ICON" (“Instrumental Complex for Ontology designatioN”) which is unde...

User interface designers still have to rely on personal creativity and skill when designing computer icons for program functions that have no existing conventional representation. Further, designers often stumble upon usable icons by trial and error. We designed an Icon Intuitiveness Test to gain better insight into how users interpret icons. Our hypothesis was that users would interpret icons ...

Handheld devices are enhancing many aspects of our lives. As increasingly complex devices appear with decreasing form factors, haptics may become an essential tool for interacting with them. In this regime of operation, issues of power, weight and volume are of significant importance. The haptic thresholds of the index finger for active exploration of a two dimensional virtual environment for t...

Emotion is one of the lovely gifts from nature. It is present not only in humans, but most species present sorts of emotions and expressions in daily behaviors. However, only human beings ask for explanations. Research into the mystery of emotion can be traced back to Heraclitus (500 BC), who claimed that “the emotional state is characterized by a mixture of body parameters such as temperature ...

This paper describes the design and use of the Interconnection Network Simulator (ICNS) framework. ICNS is a modular, object-oriented simulation system that has been developed to investigate performance issues in multiprocessor interconnection networks that exploit photonic technology in their design. We describe the ICNS infrastructure, present two distinct photonic interconnection networks th...

Introdouction: The major demand for orthodontic treatment is associated with esthetic complaints rather than with the severity of occlusal irregularities. This study evaluated the relationship between orthodontic treatment need based on index of complexity, outcome, and need (ICON) and orthodontic- specific quality of life (QOL) among high school students in Shiraz. Materials and methods: Base...

This paper examines inter-organizational innovation collaboration networks (ICNs) using a relational view of the firm perspective. This study suggests that information technology (IT) structure and firm interdependencies can be significant predictors of relational rent generation for innovation collaboration networks. Furthermore, the authors argue that the alignment of these structural propert...

Rhesus monkeys (Macaca mulatta) have shown the ability to monitor their own mental states, but fail the mirror self-recognition test. In humans, the sense of self-agency is closely related to self-awareness, and results from monitoring the relationship between intentional, sensorimotor and perceptual information. Humans and rhesus monkeys were trained to move a computer icon with a joystick whi...

How do customers make selections from among millions of smartphone apps? In this study, we analyzed the relationship between icon attributes and choice of game apps. Based on the literature, 5 icon attributes were identified: active, balance, complexity, depth, and organic. 3 game types were selected: arcade, brain, and casual games. Explicit policy implications were exploited for icon design. ...
