Industrial control hardware may be reused for several purposes. The same industrial PC type may control the drives of a portal system, act as a programmable logic controller, or control any other device. Moreover the same piece of hardware may control different device types at the same time in concurrency. In this paper, we discuss four successive software engineering approaches to exploit the ...

Task and group comparisons in functional magnetic resonance imaging (fMRI) studies are often accomplished through the creation of intersubject average activation maps. Compared with traditional volume-based intersubject averages, averages made using computational models of the cortical surface have the potential to increase statistical power because they reduce intersubject variability in corti...

This article addresses design issues that are relevant in the Autism project which aims at developing a computer games, for diagnosis and training of the children with autism and accompanying mental disorders. This approach is put in the broader context of interactive environments, which computer games are a special case. The characteristic of our approach is that it has the capability of user ...

A PC based program has been designed for analysis of EEG data using brain electrical activity mapping technique. It operates under control of MS-DOS operating system and can be used as a stand alone program or incorporated into a digital EEG system. The program can apply different map interpolation algorithms from nearest neighbours methods to spherical spline functions. It performs analyses in...

This paper presents a PC-based PCR thermal cycler with a host-local architecture, where a PC is employed as the host. The local system only executes the thermal cycling process and the PC is responsible for the management of PCR protocols with a convenient GUI. The presented host-local system greatly reduces the development time and the maintenance cost, providing an economical PCR thermal cycler.

Using a personal computer (PC) for simple visual reaction time testing is advantageous because of the relatively low hardware cost, user familiarity, and the relative ease of software development for specific neurobehavioral testing protocols. However, general-purpose computers are not designed with the millisecond-level accuracy of operation required for such applications. Software that does n...

Pen-based computing has and continues to become accepted and increasingly used. Hardware and software vendors have typically stored and represented digital ink using proprietary or restrictive ink formats, and have provided software development toolkits to access or manipulate ink for user development on their devices. The variety of digital ink formats and device-dependent software toolkits ha...

Accurate positioning is an essential element of next generation Software Defined Radio (SDR) applications such as cognitive radios, telematics, and E-9-1-1, leading to an increased demand for GPS waveforms on SDR platforms. The Software GPS Receiver (SGR) developed in-house at NAVSYS implements functionality largely in software, and uses a reprogrammable hardware platform that can also be confi...

 ABSTRACTBackground: Delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. The aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field.   Methods: The software was written based on local enhancement of the pixel values in image ma...
