Abstract: The widespread presence of uncontrolled electric vehicles causes overloading of distribution network equipment. One of these equipments is distribution transformer, which should pay attention to overloading and reducing lifetime of this equipment due to charging of electric vehicles. First, strategies have been proposed to investigate the effect of electric vehicle penetration level a...
In this paper, multi-class dynamic PERT network is considered as a queueing network, where the projects are similar and new projects are generated according to a Poisson process. Each activity is performed independently in its corresponding service station with exponential distribution by one server from several servers settled in service station based on FCFS (Fist Come, First Served) discipli...
in this paper we present a method related to extracting white blood cells (wbcs) from blood microscopic figures and recognizing them and counting each kind of wbcs. in this method, first we extract the white blood cells from other blood cells by rgb color system's help. in continuance, by using the features of each kind of globules and their color scheme, we extract a normalized feature vector,...
backgrounds: thyroid hormones play an important physiological role in human metabolism. erythrocyte abnormalities are frequently associated with thyroid disorder. however, they are rarely investigated and related to the subclinical and primary hypothyroidism in kashmiri patients. in this study an attempt was made to study hematological parameters in untreated and treated subclinical hypothyroid...
The analysis and modelling of various complex networks has received much attention in the last few years. Some such networks display a natural bipartite structure: two kinds of nodes coexist with links only between nodes of different kinds. This bipartite structure has not been deeply studied until now, mainly because it appeared to be specific to only a few complex networks. However, we show h...
We develop a new approach to the study of the dynamics of link utilization in complex networks using records of communication in a large social network. Counter to the perspective that nodes have particular roles, we find roles change dramatically from day to day. “Local hubs” have a power law degree distribution over time, with no characteristic degree value. Our results imply a significant re...
Abstract Background Hypertension is a major health problem, especially because it has no clear symptoms. It is strongly correlated with modifiable risk factors such as adiposities, age, stress, high salt intake. Overweight and obesity is conveniently determined from BMI and visceral adiposity is determined by waist circumference. ABO blood group is one such factor which needs to be investiga...
In this paper, we construct a weighted industrial cluster complex network model according to preferential attachment and local world mechanism, in which the logistics amount of business contact between one enterprise and others is defined as edge weight. We simulate and analyze statistic characteristics of the industrial cluster model such as degree distribution, point strength, point strengthp...
Grid Technology has proven to be a suitable means for the efficient sharing of various resources within a well–defined community. The EC–funded projects LeGE–WG and e–LeGI have set out to apply this technology for technology enhanced learning services. Previously, the applicability of distributed skill maps for adaptive e–Learning within a grid network has been discussed. In this paper, we prop...
This paper presents a multi-periodic, multi-echelon blood supply chain network consisting of blood donors, mobile collection units, local blood centers, main blood centers and demand points in which the local and main blood centers are subject to random failure in dispatching blood products to demand points. The problem has two objectives including minimization of the total chain costs and maxi...
