The PoC (Push-to-talk over Cellular) application allows point-to-point, or point-to-multipoint voice communication between mobile network users. The related work over PoC focuses on the performance analysis only and is completely ignorant about dimensioning PoC controller to optimize revenue for service providers. In this paper, we dimension a PoC controller with the assumption that the network...

Plain ATM (Asynchronous Transfer Mode) has poor performance in case of Data transmission. In order to improve its performance many Buffer Management Mechanisms have been proposed, e.g. push-out. The aim of this paper is to propose improved approach to push-out based on the analysis of various packet discard policies, and create a simulation model in GPSS (General Purpose Simulation System) in o...

background global health policy is created largely through a collaborative process between development agencies and aid-recipient governments, yet it remains unclear whether governments retain ownership over the creation of policy in their own countries. an assessment of the power structure in this relationship and its influence over agenda-setting is thus the first step towards understanding ...

In this note, we extend the existing algorithms Extra [13] and subgradient-push [10] to a new algorithm ExtraPush for convex consensus optimization over a directed network. When the network is stationary, we propose a simplified algorithm called Normalized ExtraPush. These algorithms use a fixed step size like in Extra and accept the column-stochastic mixing matrices like in subgradient-push. W...

In this research, we have developed the data driven computational walking model to overcome the problem with traditional kinematics based model. Our model is adaptable and can adjust the parameter morphological similar to human. The human walk is a combination of different discrete sub-phases with their continuous dynamics. Any system which exhibits the discrete switching logic and continuous d...

Most of oil and gas offshore platforms are located in the seismic regains. So, Seismic vulnerability evaluation of the offshore platforms is one of the most important and vital issues in the structural systems. In this study, jacket type offshore platforms are studied by incorporating the pushover analyses and nonlinear time history analyses, in such a way that, first some push over analyses ar...

Since the 1960s civilian technology demonstration programs in the US Departments of Transportation and Commerce have manifested a pattern in their initiation, content, and outcomes. Programs are episodic, with long periods of relative inactivity occasionally interrupted by brief periods of budgetary largesse. Program content often emphasizes information and automation technologies and system in...

Objectives: The purpose of this study was to investigate technique differences between expert and novice manual wheelchair users during over-ground wheelchair propulsion. Method: Seven experts (spinal cord injury level between T5 and L1) and six novices (non-wheelchair users) pushed a manual wheelchair over level ground, a 2.5% cross slope and up a 6.5% incline (7.2 m length) and 12% incline (1...
