Understanding and managing ecosystems as biocomplex wholes is the compelling scientific challenge of our times. Several different system-theoretic approaches have been proposed to study biocomplexity and two in particular, Kauffman’s NK networks and Patten’s ecological network analysis, have shown promising results. This research investigates the similarities between these two approaches, which...

one of the most important issues in the plant layout design especially in mass production organizations with high inter-plant logistics is‘material flow and inter-plant traffic analysis and its effects on the production capabilities or pauses in production lines. in this paper the inter-plant traffic analysis issue on the basis of single channel queue model (m/m/1) is analyzed in a carmaker c...

The free mesh method (FMM) is a kind of the meshless methods intended for particle-like finite element analysis of problems that are difficult to handle using global mesh generation, or a node-based finite element method that employs a local mesh generation technique and a node-by-node algorithm. The aim of the present paper is to review some unique numerical solutions of fluid and solid mechan...

Cytogenetic abnormalities seen at presentation of acute lymphoblastic leukemia or lymphoblastic lymphoma (ALL/ LBL) are associated with distinct clinical and hematologic disease entities. T-ALL/LBL are morphologically indistinguishable from those of B-ALL/LBL. An abnormal kariotype is found in 50-70% of cases of T-ALL/LBL. We present a 35-year old male patient with T-ALL/LBL and t(8;14)(q24;q11...

We study information flow in a model for data-parallel computing. We show how an extant notion of virtual time can help guarantee information-flow properties. For this purpose, we introduce functions that express dependencies between inputs and outputs at each node in a dataflow graph. Each node may operate over a distinct set of virtual times—so, from a security perspective, it may have its ow...

Existence of line of sight (LOS) and alignment between the communicating antennas is one of the key requirements for free-space-optical (FSO) communication. To ensure uninterrupted data flow, auto-aligning transmitter and receiver modules are necessary. We previously proposed [1] a new FSO node design that uses spherical surfaces covered with transmitter and receiver modules for maintaining opt...

In this paper we broadly generalize the assignment auction algorithm to solve linear minimum cost network flow problems. We introduce a generic algorithm, which contains as special cases a number of known algorithms, including the e-relaxation method, and the auction algorithm for assignment and for transportation problems. The generic algorithm can serve as a broadly useful framework for the d...

background: exposures to lead above the threshold value of 50–60 μg/dl have been linked to diminished semen quality parameters. worldwide, the lead exposure has been diminished during the last years. therefore, it has become of a great concern to examine the effects of lead exposures on semen quality at low levels of exposure. objective: to evaluate the effect of low level (<20 μg/dl) blood lea...

This paper deals with resource unconstrained project scheduling problems with the objective of maximizing the net present value (NPV) of project cash flows. Here we present a heuristic algorithm named as differential procedure (Dif_AOA).&#10In order to evaluate the efficiency of this algorithm, networks with node numbers between 10-1000 and network complexity coefficients between 1.3-6.6 have ...

In the new millennium, traditional electrical power systems have undergone a significant change driven by set of requirements arising from evolving and changing technology. Thus, fundamental changes occurred in way energy is produced, transmitted, distributed. This situation has revealed need to expand existing networks or establish networks. The available literature that particular attention l...
