Hubs are facilities to collect arrange and distribute commodities in telecommunication networks, cargo delivery systems, etc. In this paper, an uncapacitated phub center problem in case of single allocation and also multiple allocation will be introduced in which travel times or transportation costs are considered as fuzzy parameters. Then, by proposing new methods, the presented problem is con...

stroke is an important cause of death in the world and disability world‑wide especially in developed countries. following acute phase of stroke, some procedures and medical treatment such as thrombolytic agents has been recommended; nevertheless many patients have enduring deficits. thus, there is a realistic need to develop treatment strategies for reducing neurological deficits. however, the ...

My approach to selection of candidates for these topics is to accept nominations for each topic, and then to choose the most suitable person for the job. Expressions of interest can be made by emailing me. Expressions from multiple students are acceptable as students working on each project will work as a team. I will arrange a meeting later in 2 semester with all interested parties and will as...

Organogenesis, such as long tubule self-organization, requires long-range coordination of cell mechanics to arrange cell positions and to remodel the extracellular matrix. While the current mainstream in the field of tissue morphogenesis focuses primarily on genetics and chemical signaling, the influence of cell mechanics on the programming of patterning cues in tissue morphogenesis has not bee...

In this paper we present recent developments for interactive statistical graphics on the Web, derived from the Java–based software development kit “nViZn” (read “envision”). We demonstrate how to access and arrange data from Federal Agencies using interactive tables and micromaps. For example, the data can be sorted according to several criteria, different types of displays can be used at the s...

Szasz and others have pointed out that many so-called voluntary admissions to mental hospitals have various elements of coercion involved, and are thus not truly voluntary. The author contends that the converse situation is also true, that many patients admitted under involuntary commitment papers arrange for their own commitments. Reasons for such choices are discussed in the context of a revi...

-Authors propose the spherical electromagnetic actuator that applied Surface Motor. The feature of this actuator is the ability to arrange the magnetic poles uniformly by distributing the stator's magnetic poles in triangular lattice. In this paper, we report that the fundamental structure of this actuator and secondary side permanent magnets arrangement, and we measure the thrust force charact...

This issue’s Open Problem Column is by Ryan Williams and is on Some Open Problems Regarding Lower Bounds For NP. Ryan himself has made progress on lower bounds for SAT and is an expert in the area. I invite any reader who has knowledge of some area to contact me and arrange to write a column about open problems in that area. That area can be (1) broad or narrow or anywhere inbetween, and (2) re...

We propose an iterative algorithm for the Virtual Topology Design (VTD) in optical networks. The algorithm eliminates lighter traffic lightpaths and re-arrange the traffic through the remaining lightpaths. This tries to preserve the open capacity for the accommodation of future unknown demands. The results suggest that it is feasible to preserve enough open capacity to avoid blocking of future ...

A one-dimensional assembly of cadmium sulfide (CdS) nanoparticles was prepared by using functionalized polymers with pendant Fréchet-type dendritic wedges of different generation. The novel dendronized polymers acted as both nanoreactors for the formation of CdS nanoparticles and a template to arrange the nanoparticles into a necklace. The polymers of different dendron generation were applied t...
