In the past, viewers were constrained to watch television in front of a receiver in their home. Today, people watch video at any time and in any place. A viewer can now browse video on their desktop PC, or watch a movie outdoors on a mobile handheld device, or view HDTV (High Definition Television) in their own home theater system or at Digital Cinemas within a well controlled viewing environment.

High quality instruments are useful tools for clinical and research purposes. To determine whether an instrument has high quality, measurement properties such as reliability and validity need to be assessed, using standardised criteria. This paper discusses these quality domains and measurement properties using the standardised criteria that were recently published by the COSMIN group. Examples...

Background and Purpose—The Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) is widely used to measure health status after stroke. However, a fundamental assumption for its valid use after stroke has not been comprehensively tested: is it legitimate to generate scores for 8 scales and 2 summary measures using the standard algorithms? We tested this assumption. Methods—SF-36 data f...

The VoIP quality of service can be either estimated by analyzing the voice data flow characteristics, or by recording a transmitted voice probe over the whole VoIP transport chain and comparing it to the original. When the quality estimation by the voice data flow characteristics is deployed, the three most prominent degradation factors are observed – the packet loss, the packet delay and the d...

Web sites are now considered an extension of the entire business, not just an additional channel or storefront or a simple information portal for the company. Creating an effective web site that gives a positive overall experience to the customers and visitors is important in business today.

Sir, Measurements are very important in all activities so as to differentiate and rank among themselves. Health care services are generally administered by professionals but are received by patients and so they may have different perceptions. Doctors who are providers of health care are almost satisfied with the clinical outcomes. On the contrary, the patients are more sensitive to the treatmen...

Over the past years software architecture has become an important sub-field of software engineering. There has been substantial advancement in developing new technical approaches to start handling architectural design as an engineering discipline. Measurement is an essential part of any engineering discipline. Quantifying the quality attributes of the software architecture will reveal good insi...

s of papers 85 (PE) and PC of birds fed Diet III and IV when compared to Diet I and II. The n-6:n-3 fatty acid ratio was highest in the VT of birds fed Diet II (P<0.05). The content of lipid oxidation products as measured by TBARS assay was higher in the VT of birds fed Diet II, III, and IV when compared to Diet I (P<0.05). The total lipid content of VT constituted 3.1, 3.2, 3.0 and 3.0% for Di...

Quality of measurements is an important factor affecting the reliability of analyses in environmental sciences. In this paper we combine foliar measurement data from Finland and results of multiple measurement quality tests from different sources in order to study the effect of measurement quality on the reliability of foliar nutrient analysis. In particular, we study the use of weighted linear...
