The ISO 20462 method for subjective image quality evaluation relies on a set of reference images, which are calibrated in terms of known absolute quality differences. The original reference images, Standard Reference Stimuli (SRS), were in the form of photographic prints, to be viewed under controlled lighting and fixed viewing conditions. This method was then extended for scenes presented on c...

introduction: applying quality management systems can be useful for the development of health care organizations standards, services, quality improvement and costs reduction. the purpose of this study is to investigate the possibility of applying quality management system iso9001/2000 in hospitals affiliated with medical sciences universities from managers' viewpoints. methods and materials: it...

This paper presents a novel architecture for Home Automation Networks management through high speed Internet connections ensuring QoS support. These connections can be ADSL links, an emerging technology which provides the user of the local loop with broadband speeds. So, a remote end-user who manages a Home Automation Network can use an ADSL connection to assure the real-time transmission of im...

This paper describes ADSL (Asymmetric Digital Subscriber Line) simulation model developed using COMNET III. ADSL is integrated with IP (Internet Protocol) and ATM (Asynchronous Transfer Mode) in order to provide QoS (Quality of Service). Using this model, a comparison study between networks using IP over ATM over ADSL and IP over ADSL is provided.

This paper presents the fault detection technique in wide area power system network using Phasor Data Concentrator (PDC). Single line to ground (SLG) fault data of transmission line is processed using the WAMS technology. Phasor Data Concentrator (PDC) is primarily data collecting centres located at the control centre processing unit and is responsible for collecting all the PMUs data that is t...

Thanks to their high bandwidth ability, Asymmetric Digital Subscriber Lines (ADSL) and Very high speed DSL (VDSL) am access technologies that permit the transmission of several applications simultaneously on telephonic subscriber lines. Considering that these applications may require a different Quality of Service (QoS), and particularly different Bit Error Rates (BER), for transmission, this p...

The protein content and its type are principal factors affecting wheat (Triticum aestivum) end product quality. Among the wheat proteins, glutenin proteins, especially, high molecular weight glutenin subunits (HMW-GS) are major determinants of processing quality. Wheat and its primary gene pool have limited variation in terms of HMW-GS alleles. Wild relatives of wheat are an important source of...

− Energy transmission by high voltage direct current – HVDC is steadily increasing in the world, both at the highest power levels, but also at medium power, for example in connections of remote wind-parks to the main a.c. grid. Although principles for d.c. side measurements are known since long, support from metrology is not on par with the needs. An overview of available technologies and the c...
