The potential exists for an increasing population of older Web users, who tend to have a high disposable income, to become a major factor in the success and profitability of e-Commerce websites. Due to the natural ageing process, this group are subject to a decline in their visual, motor and cognitive abilities. These age-related impairments form the major barriers that adversely affect both We...

In general game playing [5], game rules are communicated at runtime, and the players must be able to read and understand the descriptions they are given in order to play legally and effectively. Unlike specialized game players, such as Deep Blue, general game players cannot rely on algorithms designed in advance for specific games. General game playing expertise depends on intelligence on the p...

Invasive Computing enables a resource-aware programming style, which includes adapting to external resource changes similar to malleability. We introduce asynchronously-malleable applications, which can adapt at any time without synchronizing the whole application, in contrast to specific synchronization points. We show how master-slave applications meet the requirements for asynchronous mallea...

A haptic device using flexible sheet such as rubber has already been proposed. Controlling the bias tension of the sheet, the device varies compliance of the sheet in the normal direction; users can feel compliance of various virtual objects if they touch the sheet. This device is integrated into a visual and haptic display. The haptic device uses transparent flexible sheet, and a liquid crysta...

soil detachment is known as an important process in soil erosion and its quantification is necessary to establish a basic understanding of erosion. this study was carried out to find the best flow erosivity indicator(s) for predicting detachment rate at low slopes. for this purpose, 12 experiments including 6 flow discharges (75, 100, 125, 150, 175 and 200 ml/s) and 2 slope gradients (1.5 and 2...

A well-founded data model for Conceptual Structures can help in understanding issues of definitional semantics, efficient implementations and even syntax of proposed languages. This paper presents several useful data models of increasing complexity and applicability that can support Conceptual Structures definitional semantics. The models are presented in Haskell, a non-strict, stronglytyped fu...

recently, incremental sheet metal forming (ismf) process as one of the new methods in rapid prototyping collection has been considered by researchers. this process is based on a defined path in cnc controller and applies a spherical-head tool that supplies the required pressure for sheet metal forming. despite affirmation of process ability in forming symmetric geometries, some of its aspects s...

in this work, a bench-scale process was developed using mineral-processing methods to recover iron from a placer deposit located in bardaskan, khorasan-e-razavi, iran. the mineralogical studies were performed by x-ray diffraction (xrd), x-ray fluorescence (xrf), electron probe micro-analyzer (epma), and an optical microscope. these studies indicated that titanomagnetite, magnetite, and hematite...

the present study investigated any probable relationship between theidentity processing styles and l2 literacy of advanced persian efl learners. theparticipants included 160 (female = 109, male = 51) advanced efl iranian learners.the instruments used included a simulation of the toefl ibt test, measuring theparticipants’ l2 literacy-related proficiency, reading, and writing, and the identitysty...
