Various methods have been presented to improve the performance of buildings against earthquakes. Friction damper device is one of the energy dissipation devices that appropriately absorbs and dissipates the input energy and decreases displacements. In this paper, the possibility of using endurance time method to determine the efficiency index and optimum slip load for these dampers was investig...

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...

Services provided Over-The-Top to Internet users are becoming more advanced and the business models for operating in this domain are becoming more sustainable. When services of this type are something which is paid for, the importance of optimizing Quality of Experience (QoE) is crucial. In this paper we study and test a selected mechanism PostACK for controlling TCP flows, and implement a home...

In drilling of composite laminates, it is important to minimize or reduce occurrences of delaminations. In particular, a peel-up delamination at entrance and push-out delamination at exit are common. Delaminations may be avoided by regulating the drill thrust force can be controlled by adjusting the feedrate of the drill. Dynamics involved in drilling of composite laminates is time varying and ...

In this paper, we propose a versatile scheduling discipline, called Precedence with Partial Push–out (PPP), in Asynchronous Transfer Mode (ATM) switches supporting two delay and two loss priorities. By employing a threshold L, PPP provides delay guarantee by allowing a newly–arriving highdelay–priority cell to precede a maximum of L low-delay– priority cells. Through the use of another threshol...
