Let R be a ring with center Z(R). We write the commutator [x, y] = xy− yx, (x, y ∈ R). The following commutator identities hold: [xy,z] = x[y,z] + [x,z]y; [x, yz] = y[x,z] + [x, y]z for all x, y,z ∈ R. We recall that R is prime if aRb = (0) implies that a= 0 or b = 0; it is semiprime if aRa = (0) implies that a = 0. A prime ring is clearly a semiprime ring. A mapping f : R→ R is called centrali...
We present quantitative statistical evidence for a γ-ray emission halo surrounding the Galaxy. Maps of the emission are derived. EGRET data were analyzed in a waveletbased non-parametric hypothesis testing framework, using a model of expected diffuse (Galactic + isotropic) emission as a null hypothesis. The results show a statistically significant large scale halo surrounding the center of the ...
Quantifying roughness effects on ground surface emissivity is an important step in obtaining high-quality soil moisture products from large-scale passive microwave sensors. In this study, we used a semi-empirical method to evaluate roughness effects (parameterized here by the parameter) on a global scale from AMSR-E (Advanced Microwave Scanning Radiometer for EOS) observations. AMSR-E brightnes...
Expectations for design and evaluation approaches are set by the development practices within which they are used. WorthCentred Development (WCD) seeks to both shape and fit such practices. We report a study that combined two WCD approaches. Sentence completion gathered credible quantitative data on user values, which were used to identify relevant values and aversions of two player groups for...
Map/Reduce approach has been popular in order to compute huge volumes of data since Google implemented its platform on Google Distributed File Systems (GFS) and then Amazon Web Service (AWS) provides its services with Apache Hadoop platform. Map/Reduce motivates to redesign and convert the existing sequential algorithms to Map/Reduce algorithms for big data so that the paper presents Market Bas...
One of our first activities in natural resources management and development programs is to acquire knowledge on Landslide Susceptible areas. The aim of this research is landslide hazard zonation in some part of Haraz watershed between Vana village and Emam zadeh Ali, using fuzzy membership functions and fuzzy operators. At first landslide points were recognized using arial photography and field...
One of the slopping processes which creates tremendous damage in many locations of Iran and the world is landslide phenomenon. Creating a landslide susceptibility map provides the possibility to recognize susceptible areas and to verify them in the environmental programs. The purpose of this research is to map the susceptibility of landslide in Taleghan watershed by establishing informational l...
