Background The performance of TVS, TRS and MRI for the diagnosis of DIE have been separately reported in earlier studies. However, the three methods have not been concurrently compared in terms of their overall performance and classified results as per different anatomical locations of DIE lesions in a large study population. This study was an attempt to compare pelvic magnetic resonance imagin...

in this study 121 prescapular, prefemoral and popliteal lymph node of male healthy camel from mashhad abattoir were collected. after collecting of specimens factors such as: length, width, thickness, weight, volume and density of each lymph node were measured by caliper device. all factors were analyzed and compared using excel program. it was revealed that, normal dimensions of right prescapul...

Wireless Sensor Networks (WSNs) consists of large number of energy constrained sensor nodes that are randomly deployed. Sensor nodes have the ability to sense and send data towards the base station (BS). Sensor nodes require large amount of energy for data transmission. So while transmission, some nodes die because of energy depletion. In this case, chance of data loss increases. In order to re...

Hypergraphs are generalizations of graphs where an edge can consist of more than two nodes. A reoccurring task is to divide the node set of a hypergraph into k different non-empty parts where we simultaneously want to minimize a partitioning objective. This problem is called the k-way hypergraph partitioning problem. Applications can be found in the area of VLSI design and the parallelization o...

Aluminum extrusion die manufacturing is a critical task for productive improvement and increasing potential of competition in aluminum extrusion industry. It causes to meet the efficiency not only consistent quality but also time and production cost reduction. Die manufacturing consists first of die design and process planning in order to make a die for extruding the customer’s requirement prod...

Das Benzoldimer ist ein Prototypsystem f r die Untersuchung nichtkovalenter Wechselwirkungen zwischen aromatischen Systemen, die durch Dispersionskr fte bestimmt werden. Es weist zwei miteinander konkurrierende Gleichgewichtsstrukturen auf: eine gekippte, T-fçrmige (edge-toface) und eine, in der die beiden Benzolringe parallel angeordnet, aber zueinander verschoben sind (stacked). Sowohl der ve...

Deutschland steht 2009 vor einem überaus schwierigen Jahr. Vorausschauende Manager schielen aber weniger auf die nicht beeinflussbaren Eckdaten, sondern finden heraus, welche Verbesserungspotenziale in ihrer Firma schlummern. Eine Alternative zu Cost-Cutting-Programmen kann die Optimierung des Projektmanagements sein. Ein kritischer Blick auf den Markt der dafür erforderlichen Projektmanagement...

High speed and absence of a precise control over pressure distribution confine sheet Electromagnetic Forming into a die to simple shapes having shallow depth. It is possible to reach a higher depth by using a convex punch instead of a concave die. In this study, sheet Electromagnetic Forming on a punch and sheet Electromagnetic Forming into a die are investigated. The electromagnetic part of th...

The hydrostatic extrusion is a new method of extrusion process. The most important advantage of this method is reduction of friction and close tolerance for the coating thickness. In this study, the hydrostatic extrusion simulation of bimetallic wires has performed using of finite element method. In the following the advantages of hydrostatic extrusion compared to the direct extrusion are prese...
