A model is developed that allows simulating the most-likely failures possibly occurring in freecooling (FC) systems of telecommunication (TLC) switching rooms. Main aim to provide an effective and online implementable diagnosis method, which turn will allow fulfilling threefold function safeguarding electronic equipment, ensuring desired air quality case human presence reducing malfunction-rela...

In this paper we present the notion of Social Instruments as a set of mechanisms that facilitate the emergence of norms from repeated interactions between members of a society. Specifically, we focus on two social instruments: rewiring and observation. Our main goal is to provide agents with tools that allow them to leverage their social network of interactions when effectively addressing coord...

In this study, construct validity of 2 pain behaviour observation measurement instruments for young children aged 1 to 56 months (mean age was 20 months) with burns is assessed by using Rasch analysis. The Rasch model, wherein data should meet the model expectations, assumes that an instrument measures one unidimensional construct, and focuses on the items of measurement instruments. The Pain O...

introduction: this study investigated the fatigue and fracture modes of race and protaper rotary instruments. materials & methods: fatigue resistance was evaluated by rotating the files 30 ° or 60 ° and with 2 or 5mm radius of curvature. race taper 06 size 25 and protaper f1 files (n=40) were used. the number of rotations to failure was analyzed by two-way anova and independent sample     t-tes...

Original scientific paper MODIS and CALIOP are two independent observation instruments in the A-train satellite constellation. They both provide aerosol optical depth (AOD) retrievals and scan the same points on the Earth’s surface within a two-minute interval. With different design principles, MODIS and CALIOP instruments obtain varying AOD retrieval accuracies under different conditions. In t...

abu al-qasim khalaf ibn-e-abbas zahrawi(936-1013 a.d.), known as albucasis in west, was one of the greatest physicians in the islamic world. to many historians, he was considered as the father of modern surgery. his book, al-tasrif, e.g., written in 30 chapters, was, in fact, a medical encyclopedia of that era. it was used as one of the main references in medical academic centers for centuries....
