In this paper we present DIVA, an architecture for Intelligent Virtual Environments. In DIVA, systems consist of three different modules. There is a World Server that represents the environment in an abstract way, an arb itrary number of Intelligent Agent Clients acting as the world’s inhabitants and a set of Visualisation Clients that generate the system’s visual output. All client modules are...

With the advent of DIVA style correctness checking [1], processor architecture becomes much less constricted, to the point that even an entirely nonfunctional processor with a DIVA checker will produce correct results. Without the need for absolute correctness, processor designs that work “most of the time” are still acceptable. In this paper, we examine input dependent architecture variance (A...

As a processor gets smaller and faster, it becomes more sensitive to both the increasing process variation and environment disturbances such as cosmic rays and heat. These imperfections and uncertainties lead to transient errors or even destructive malfunctions of the processor. The previous effort on processor execution error detection includes the DIVA scheme [1], which excels other dynamic v...

The Distributed Interactive Video Array (DIVA) system is developed to provide a large-scale, redundant cluster of video streams to observe a remote scene and to supply automatic focus-of-attention with event-driven servoing to capture desired events at appropriate resolutions and perspectives. Installing multiple sensors introduces several new research issues related to the system design, inclu...

The Data-Intensive Architecture (DIVA) system employs Processing-In-Memory (PIM) chips as smartmemory coprocessors. This architecture exploits inherent memory bandwidth both on chip and across the system to target several classes of bandwidth-limited applications, including multimedia applications and pointer-based and sparse-matrix computations. The DIVA project has built a prototype developme...

We have constructed an easy-to-use portable, wearable gesture-to-speech system based on the Glove-TalkII and GRASSP gesture-controlled speech systems and a vizeme based face-synthesizer. Our new portable system is called a Digital Ventriloquized Actor (DIVA) and refines the use of the formant speech synthesizer. Using a DIVA, a user can speak using hand gestures mapped to both synthetic sound a...

DIVA (differentiating infected from vaccinated animals) vaccines have proven extremely useful for control and eradication of infectious diseases in livestock. We describe here the characterization of a serologic marker epitope, so-called epitope-M201, which can be a potential target for development of a live-attenuated DIVA vaccine against porcine reproductive and respiratory syndrome virus (PR...

BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) often persists into adulthood. This study was designed to estimate the prevalence of ADHD in adult psychiatric outpatients in several European countries. METHOD ADHD diagnosis was made using the Diagnostic Interview for ADHD in Adults, version 2.0 (DIVA), according to criteria of the Diagnostic and Statistical Manual of Mental Disorde...

The option of vaccinating poultry against avian influenza (AI) as a control tool is gaining greater acceptance by governments and the poultry industry worldwide. One disadvantage about vaccination with killed whole-virus vaccines is the resulting inability to use common serologic diagnostic tests for surveillance to identify infected flocks. There has been considerable effort to develop a relia...
