This study presents an optical inspection system for detecting a commercial point-of-care testing product and a new detection model covering from qualitative to quantitative analysis. Human chorionic gonadotropin (hCG) strips (cut-off value of the hCG commercial product is 25 mIU/mL) were the detection target in our study. We used a complementary metal-oxide semiconductor (CMOS) sensor to detec...

The wide adoption of underground mining has contributed immensely to the rapid growth of the countries’ economy, job creation, gross domestic product, fixed capital formation, gross investment and merchandise exports on an enormous global scale. At the same time, the tedious and dangerous nature of underground mining makes it vulnerable to mine accidents and disasters, such as the fall of loose...

background: to correct patient positioning errors (setup errors) during prostate cancer treatment using epid and fiducial gold markers, to improve the accuracy of the dose delivery in these patients. materials and methods: fifteen patients with localized prostate carcinoma after implantation of fiducial gold markers in their prostate gland underwent the five-field imrt planning technique. the p...

We present a pole inspection system for outdoor environments comprising a high-speed camera on a vertical take-off and landing (VTOL) aerial platform. The pole inspection task requires a vehicle to fly close to a structure while maintaining a fixed stand-off distance from it. Typical GPS errors make GPS-based navigation unsuitable for this task however. When flying outdoors a vehicle is also af...

Software inspections, which were originally developed by Michael Fagan in 1976, are an important means to verify and achieve sufficient quality in many software projects today. Since Fagan’s initial work, the importance of software inspections has been long recognized by software developers and many organizations. Various proposals have been made by researchers in the hope of improving Fagan’s ...

background: the hygienic issues are the essential criteria in the primary site selection, compatibility and maintain of passengers health after use of the services. qom with 17 million annual tourists is the second religious tourism center in iran. the aim of this study was to investigate the impact of the public residential centers internal managers’ educational status on their environmental h...

in this paper, absorbing markov chain models are developed to determine the optimum process mean levels for both a single-stage and a serial two-stage production system in which items are inspected for conformity with their specification limits. when the value of the quality characteristic of an item falls below a lower limit, the item is scrapped. if it falls above an upper limit, the item is ...

We consider state-space specifications of autoregressive moving average models (ARMA) and structural time series models as a framework to formulate and estimate inspection and deterioration models for transportation infrastructure facilities. The framework provides a rigorous approach to exploit the abundance and breadth of condition data generated by advanced inspection technologies. From a ma...

uality is an elusive goal throughout the software development industry. The common assumption is that there simply is no efficient way to improve quality without significantly lengthening the development cycle, increasing development costs, or both. Releasing quality software on schedule and on budget is almost impossible. Ever-shorter development cycles, limited engineering and QA resources, a...
