The load-carrying capacities of welded joints need to be paid attention in the design frame, which transfers thrust generated by rocket engine body. A capacity evaluation method based on structural stress is proposed this study. Both ultimate and fracture section angle are precisely obtained method. At same time, a definition weld-failure given tests. frame analyzed through finite element model...

The normal carrying angle in Shiraz population was measured on the basis of sex and age. The right elbow angle of 4266 cases was examined from birth to 30 years old. This study found the carrying angle in 2540 females to be 7.20 (range 2-19) and in 1726 males to be 6.40 (range 2-11), a 0.80 difference. A significant difference (p= 0.05) was found in relation to age. There is a gradual incr...

The number of companies operating globally is constantly increasing. In order for these companies to operate globally, they require a global view of processes and their implementation in global enterprise resource planning (ERP) systems. These ERP systems allow to integrate an organization’s information sources and to harmonize its processes across multiple sites and countries. But, not all glo...

Proof-Carrying Code (PCC) enables a computer system to determine, automatically and with certainty, that program code provided by another system is safe to install and execute without requiring interpretation or run-time checking. PCC has applications in any computing system in which the safe, eecient, and dynamic installation of code is needed. The key idea of Proof-Carrying is to attach to th...

An extended economic production quantity (EPQ) model under stochastic demand is investigated in this paper, where a fixed lot sizing policy is implemented to reduce the complexity of production planning and inventory control, and outsourcing with a secondary facility is used to supplement the lot sizing policy and to cope with the random demand. The considered cost includes: setup cost for the ...

Currently there are no Internet access authentication protocols available that are lightweight, can be carried over arbitrary access networks, and are flexible enough to be re-used in all the likely future ubiquitous mobility access contexts. This article proposes the PANA/UMTS authentication protocol for heterogeneous network access as a step towards filling this gap. A security analysis of th...
