iran’s industry has had a considerable number of difficulties to perform so well as was expected in the post – revolutionary era. unfavorable legal, political environments combined with eight –year imposed war may be singled out as the root causes of such performances. however, this paper argues that our industry’s lack of realization of its dire need to adapt to the emerging unprecedented envi...

This paper addresses the issue of hybridization between reactive and cognitive approaches within a single decision-making architecture for virtual agent in an urban simulation. We use a reactive module in order to manage reactive behaviors and agent autonomy, and a cognitive module for anticipation, learning and complex behaviors management. The purpose of the cognitive module is to increase th...

A virtual reality tool is presented which allows to display the activity of a human operator performing a routine which involves manipulation with objects. This tool represents a presentation module of the running EU project ActIPret. The project stresses mainly the cognitive vision aspects and aims at interpretation and understanding of expert activities for teaching and education purposes. Th...

We report progress on adding affect-detection to a program for virtual dramatic improvisation, monitored by a human director. To aid the director, we have partially implemented emotion detection. within users’ text input. The affect-detection module has been used to help develop an automated virtual actor. The work involves basic research into how affect is conveyed through metaphor and contrib...

Post-secondary institutions are looking for ways to provide virtual computing labs to students. Using the open source systems Apache VCL and OpenStack, as well as a preexisting OpenStack provisioning module for Apache VCL, we implemented a pilot project to provide virtual computing labs. As the pilot continued we altered and improved our implementation and discovered new requirements. These imp...

The traditional approach to assessing neurocognitive performance makes use of paper and pencil neuropsychological assessments. This received approach has been criticized as limited in the area of ecological validity. While virtual reality environments provide increased ecological validity, they are often done without taking seriously the demands of rigorous research design and control for poten...

At present, the main research in Evolvable Hardware (EHW) field is focused on the intrinsic evolution based on the virtual reconfigurable circuit. On the basis of previous researches, we take a further explore on designing a virtual reconfigurable architecture for intrinsic evolvable hardware, and propose a virtual circuit architecture based on Look-Up-Table, each evolution module of which can ...

This paper describes a new mesh-connected SIMD architecture, called a Sliding Memory Plane (SIiM) Array Processor. On SIiM, the inter-processing element (inter-PE) communication, using the sliding memory plane, and the data input/output (I/O), using two U 0 planes, can occur without interrupting the PE’s, which greatly diminishes the communication and I/O overhead. SliM is unique in its ability...

Virtual function calls are one of the most popular control-flow hijack attack targets. Compilers use a virtual function pointer table, called a VTable, to dynamically dispatch virtual function calls. These VTables are read-only, but pointers to them are not. VTable pointers reside in objects that are writable, allowing attackers to overwrite them. As a result, attackers can divert the control-f...
