This paper presents an evaluation of two commonly accepted Raman linewidth models typically used to fit CARS model parameters data; the Modified Exponential Gap (MEG) and Energy Corrected Sudden (ECS) models. The adjustable in each have been published experimental linewidths, comparisons are made various publications that already provided similar constants. approaches presented literature discu...

The proton spectrum of single crystals of Cu(NOs)2-2 ) Hz0 is studied between 0.3 and 1 OK. Fields up to 47 kOe were applied along the b axis. The field and temperature dependence of the magnetization obtained from these measurements can be described by an interpair exchange coupling zJ'/k = 1.9 OK that generates a transverse ordering below a critical temperature of 0.45 OK. Introduction. Low f...

Let Pe2n denote the subposet obtained by selecting even ranks in the partition lattice P2n. We show that the homology of Pe2n has dimension (2n)! E2n-1, where E2n-1 is the tangent number. It is thus an integral multiple of both the Genocchi number and an Andre or simsun number. Using the general theory of rankselected homology representations developed in [22], we show that, for the special cas...

The estuary tides affect groundwater dynamics; these areas are susceptible to waterlogging and salinity issues. A study was conducted on two fields with a total area of 60 hectares under center pivot irrigation system that works solar energy belong commercial farm located in Northern Sudan. To monitor soil calcium carbonate the stop future degradation resources, easy, non-intrusive, practical p...

In this paper we address the Length Constrained K-Drones Rural Postman Problem (LC K-DRPP). This is a continuous optimization problem where fleet of homogeneous drones have to jointly service (traverse) set (curved or straight) lines network. Unlike vehicles in classical arc routing problems, drone can enter line through any its points, portion that line, exit another then travel directly point...

this research was done in order to submit a model for salinity map made with tm satellite data and salinity values in a buienzahra. the necessary processings such as principal component analysis and producing of different indices was done on the main bands. the 38 soil samples using random sampling (with 10×10 km dimension) from different horizons were designed and performed on the study area. ...
