emittance control in high power linacs
چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
Array control for high-performance SIMD systems
Although arrays of SIMD PEs can be built with very high operating frequencies, problems exist in keeping the array busy. The inherent mismatch between host and array makes it difficult to maintain high array utilization: either the rate of instruction issue is very low or PE data locality is compromised, having the same effect. Our solution is based on an array control unit (ACU) design that ex...
متن کاملControl Flow Emulation on Tiled SIMD Architectures
Heterogeneous multi-core and streaming architectures such as the GPU, Cell, ClearSpeed, and Imagine processors have better power/ performance ratios and memory bandwidth than traditional architectures. These types of processors are increasingly being used to accelerate compute-intensive applications. Their performance advantage is achieved by using multiple SIMD processor cores but limiting the...
متن کاملEnhanced Iteration Control for Ultra Low Power LDPC Decoding
Today's and tomorrow's wireless systems and applications require high throughput and low latency. Additionally low energy consumption and efficient air bandwidth usage are very important to provide mobile services anytime and anywhere. Channel coding is one of the key techniques to fulfill these requirements. LDPC codes are used in current and upcoming standards due to their outstanding communi...
متن کاملEnhanced Transmission Power Control Mechanism based on RSSI for MANET
Today’s power consumption is the critical issue in MANET. Since, we have limited battery power to operate nodes. Due to the lack of power (Energy), the nodes “die out” from the network. Recently, power control in mobile ad hoc networks has been the focus of extensive research. Energy of nodes is consumed according to transmission power required by the radios. In this paper, we develop a mechani...
