DiStefano, Frank, III; Wobick, Craig; Chapman, Kirt; McCloud, Peter 2012-01-01 The Personal Computer Transport Analysis Program (PCTAP) is C software used for analysis of thermal fluid systems. The program predicts thermal fluid system and component transients. The output consists of temperatures, flow rates, pressures, delta pressures, tank quantities, and gas quantities in the air, along with air scrubbing component performance. PCTAP s solution process assumes that the tubes in the system are well insulated so that only the heat transfer between fluid and tube wall and between adjacent tubes is modeled. The system described in the model file is broken down into its individual components; i.e., tubes, cold plates, heat exchangers, etc. A solution vector is built from the components and a flow is then simulated with fluid being transferred from one component to the next.
Tutorial: Creating A FoxPro Application Dr. Hicks Computer Science Department Trinity University Organize Files & Create Directories/Folders. Add a main program in which to launch your application and a code file in which to store all of your button code.
The solution vector of components in the model file is built at the initiation of the run. This solution vector is simply a list of components in the order of their inlet dependency on other components. The component parameters are updated in the order in which they appear in the list at every time step. Once the solution vectors have been determined, PCTAP cycles through the components in the solution vector, executing their outlet function for each time-step increment. Hara, Hiroshi; Handa, Madoka; Watanabe, Yoshihiko 1990-01-01 The method of automating the judgement works using photographs in radiation nondestructive inspection with a simple type image processor on the market was examined. The software for defect extraction and making binary and the software for automatic judgement were made for trial, and by using the various photographs on which the judgement was already done as the object, the accuracy and the problematic points were tested. According to the state of the objects to be photographed and the condition of inspection, the accuracy of judgement from 100% to 45% was obtained.
The criteria for judgement were in conformity with the collection of reference photographs made by Japan Cast Steel Association. In the non-destructive inspection by radiography, the number and size of the defect images in photographs are visually judged, the results are collated with the standard, and the quality is decided.
Recently, the technology of image processing with personal computers advanced, therefore by utilizing this technology, the automation of the judgement of photographs was attempted to improve the accuracy, to increase the inspection efficiency and to realize labor saving.

Universitaetsklinik fuer Hals-Nasen-Ohrenheilkunde, Wien (Austria); Czerny, C. Universitaetsklinik fuer Radiologie, Wien (Austria) 1997-12-01 In the last decade, the rehabilitation of postlingually deaf adults and prelingually deaf children with cochlear implants has been established as a treatment of deafness.
The technological development of the implant devices and improvement of the surgical technique have led to a considerable increase of hearing performance during the last years. The postlingually deaf adults are able to use the telephone and may be integrated in their original job. Prelingually deaf children can even visit normal schools after cochlear implantation and hearing rehabilitation training. In order to preoperatively establish the state of the cochlear, radiological diagnosis of the temporal bone is necessary.
High resolution computerized tomography imaging of the temporal bone with coronar and axial 1 mm slices and MRI with thin slice technique (three dimensional, T2 weighted turbo-spinecho sequence with 0.7 mm slices) have proved to be valuable according to our experience. Furthermore a postoperative synoptical X-ray, in a modified Chausse III projection, offers good information about the position of the implant and insertion of the stimulating electrode into the cochlea. (orig.) Deutsch In der letzten Dekade hat sich der operative Einsatz von Cochlearimplantaten fuer die Rehabilitation taubgeborener Kinder und ertaubter Erwachsenen als erfolgreiche Therapie etabliert. Durch technische Weiterentwicklung der Implantatsysteme und Verbesserung der Operationstechnik konnten in den letzten Jahren die Hoerleistungen der Patienten deutlich verbessert werden. Postlingual ertaubte Erwachsene koennen nun oftmals wieder ins Berufsleben eingegliedert werden und praelingual ertaubte Kinder koennen regulaere Schulen besuchen. Im Rahmen der Voruntersuchung fuer die Cochlearimplantation ist die radiologische Felsenbeindiagnostik von besonderer Bedeutung.

1994-01-01 Processing of CT images was attempted by using a popular personal computer. The program for image-processing was made with C compiler. The original images, acquired with CT scanner (TCT-60A, Toshiba), were transferred to the computer by 8-inch flexible diskette. Many fundamental image-processing, such as displaying image to the monitor, calculating CT value and drawing the profile curve. The result showed that a popular personal computer had ability to process CT images. It seemed that 8-inch flexible diskette was still useful medium of transferring image data. (author).
Nakagawa, T.; Wargocki, Pawel; Tanabe, S. 2003-01-01 Chemical emission measurements from different brands of personal computers (PCs) were conducted in a 1 m3 glass chamber.

Downing, John P.; Bauer, Frank H.; Thorpe, Christopher J. 1989-01-01 The ASTEC (Analysis and Simulation Tools for Engineering Controls) software is under development at Goddard Space Flight Center (GSFC). The design goal is to provide a wide selection of controls analysis tools at the personal computer level, as well as the capability to upload compute-intensive jobs to a mainframe or supercomputer.
The project is a follow-on to the INCA (INteractive Controls Analysis) program that has been developed at GSFC over the past five years. While ASTEC makes use of the algorithms and expertise developed for the INCA program, the user interface was redesigned to take advantage of the capabilities of the personal computer. The design philosophy and the current capabilities of the ASTEC software are described. Craig 2012-06-01 Full Text Available This paper discusses aspects of a collaborative investigation of embodied computing and personal manufacturing. We describe the NeuroMaker 1.0, an artwork that playfully implements the concept of “translating of the designer’s ideas into a product”. Visitors to the installation were invited to use their own EEG to fabricate personalized physical objects.
While primarily intended to provoke thought about the process of creativity, we also demonstrated that, with the right team, radical new interfaces are well within the reach. Will, H.; Mackin, M.

Tak, Sunghee H; Zhang, Hongmei; Patel, Hetal; Hong, Song Hee 2015-06-01 The study examined participant's experience and individual characteristics during a 7-week computer activity program for persons with dementia. The descriptive study with mixed methods design collected 612 observational logs of computer sessions from 27 study participants, including individual interviews before and after the program. Quantitative data analysis included descriptive statistics, correlational coefficients, t-test, and chi-square. Content analysis was used to analyze qualitative data.
Each participant averaged 23 sessions and 591min for 7 weeks. Computer activities included slide shows with music, games, internet use, and emailing. On average, they had a high score of intensity in engagement per session.
Women attended significantly more sessions than men. Higher education level was associated with a higher number of different activities used per session and more time spent on online games. Older participants felt more tired. Feeling tired was significantly correlated with a higher number of weeks with only one session attendance per week. More anticholinergic medications taken by participants were significantly associated with a higher percentage of sessions with disengagement. The findings were significant at p.
