Introduction Interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. The effect of applicator attenuation is not considered in dose calculation method released by AAPM-TG43. In this study, the effect of High-Dose Rate (HDR) brachytherapy esophageal applicator on dose distribution was surveyed in HDR brachytherapy. Materials and Methods A cylindrical PMMA phan...

The design of electricity markets determines the technologies, services and modes operation that can access value, consequently shaping current future landscapes. This paper highlights efficacy Great Britain’s market in facilitating net zero is inadequate must be reconfigured. rules are remnants an sector dominated by large-scale, centralised, fossil fuel technologies. Therefore, routes to for ...

This paper proposes a parameterized digital signal processor (DSP) core for an embedded digital signal processing system designed to achieve demodulation/synchronization with better performance and flexibility. The features of this DSP core include parameterized data path, dual MAC unit, subword MAC, and optional function-specific blocks for accelerating communication system modulation operatio...

While suppliers of digital signal processing (DSP) chips and programmable logic may differ over which device type is pre-eminent for new wireless system designs, what is important is what customers are actually implementing. Today, designers are applying a mix of both PLDs and DSP chips to meet market demand. The “intelligent partitioning” between these two device types gives wireless systems t...

The emerging need for high data rate wireless services has raised considerable interest in MC-CDMA systems. In this work, we describe an MC-CDMA system design process for indoor propagation scenarios. The system specifications and simulations are firstly given, and then implementation aspects on a mixed, multi-DSP and FPGA architecture are presented. In order to reduce development cycle, we pro...

Arti cial Neural Networks (NNs) are high parallel structures that consist of a large number of elementary non-linear units (called neurons) fully interconnected. In this article we present a hardware implementation of NNs combined with a DSP; both NNs and DSP combined together results in a powerful system used in control applications. NNs process most of the control tasks, while DSP performs si...

Nowadays, most of the electronic devices used Digital Signal Processing (DSP). This paper discussed the block diagram, radar detection, implementation of a convolution, Doppler processing, scanning, compression and filtering that been used in the applications of DSP in Radar purposes. Keywords–Digital Signal Processing (DSP), Filter, Pulse, Radar, System

the harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. this paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. the objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...

Digital Signal Processing (DSP) has become today an integral part of the basic skills required for scientists and engineers of many specialties. Most courses offer only using for DSP laboratory classes the Matlab system. This approach has the disadvantage – it excludes the students’ acquisition of the basic skills of software development for implementation of DSP algorithms based on real digita...
