The three-dimensional (3D) rotation about any axis is essential in diverse applications and fields, particularly in computer graphics. This paper focuses on accelerating the operation of this transform using GPU in a real-time environment. This special type of rotation is complicated compared to rotation about the conventional axes due to having many matrix operations, so accelerating such a transform with parallel techniques is an important issue to reduce the execution time that is important to ensure the realistic view of 3D animation scene. In addition to that, concatenating these many operations in a single rotation matrix also gives a significant reduction in computation time required to perform the rotation. The rotation transform is applied to complex models with hundreds or even millions of vertices, so standard 3D objects with different resolutions are used for testing the rotation about a selected axis that created interactively using LabVIEW and Visual Studio software environments. The experimental results showed the significant speedup on CUDA/C++ compared to LabVIEW computations for the same model complexity.
围绕任何轴的三维(3D)旋转在各种应用和领域,特别是在计算机图形学中是必不可少的。本文的重点是在实时环境下利用GPU加速该变换的运算。这种特殊类型的旋转由于需要进行大量的矩阵运算,相对于传统的绕轴旋转来说比较复杂,因此利用并行技术加速这种转换是减少执行时间的一个重要问题,对于保证3D动画场景的真实感至关重要。除此之外,将这些操作连接到一个旋转矩阵中也可以显著减少执行旋转所需的计算时间。旋转变换适用于具有数百甚至数百万个顶点的复杂模型,因此使用不同分辨率的标准3D对象来测试使用LabVIEW和Visual Studio软件环境交互式创建的选定轴的旋转。实验结果表明,在相同的模型复杂度下,CUDA/ c++比LabVIEW计算有显著的加速。

A network that has recently received a lot of interest is the Vehicular Ad hoc Network VANET. Vehicle – to – Vehicle V2V communication is the conventional method in VANET communication, where vehicles can share information regarding the road status such as a warning message related to the incidence of an accident. The aim of this paper is the use of Multiple – Input – Multiple – Output MIMO diversity technique called Alamouti Space-Time Block Coding STBC as a channel coding in V2V communication. The simulation tests were constructed according to the conditions of vehicles speeds, modulations and the distances between the vehicles. These tests included both symmetric and asymmetric channels. The results showed that Alamouti STBC is suitable for slow fading channel communication rather than for mobility communication such as V2V.

In this paper, we present a discussion panel of two of the hottest topics in this area namely distributed parallel processing and distributed cloud computing. Various aspects have been discussed in this review paper such as concentrating on whether these topics are discussed simultaneously in any previous works. Other aspects that have been reviewed in this paper include the algorithms, which simulated in both distributed parallel computing and distributed cloud computing. The goal is to process the tasks over resources then readjusted the calculation among the servers for the sake of optimization. These help us to improve the system performance with the desired rates. During our review, we presented some articles which explain the designing of applications in distributed cloud computing while some others introduced the concept of decreasing the response time in distributed parallel computing.

Convolutional neural network (CNN) is a multilayer architecture, and considered as a robust model for image recognition. Learning in this neural network achieves progressively in its successive layers such that the layers produce higher-level features and the categories are produced by the last layer. To use the CNN in different real time applications, high performance implementation is required. To reduce the resources required for implementation, in this paper a time sharing based parallel implementation of CNN is proposed. The computing of the upper convolution nodes is done sequentially while the parallelism is increased in the direction of the preceding layer resulting maximum parallelism in the bottom layer Then the CNN relatively complex design is implemented on an FPGA model with no more than 200,000 gates and can speed up computation up to 166 times.
卷积神经网络(CNN)是一种多层结构,被认为是一种鲁棒的图像识别模型。该神经网络的学习在其连续的层中逐步实现,使得层产生更高级别的特征,而类别由最后一层产生。为了在不同的实时应用中使用CNN,需要高性能的实现。为了减少实现所需的资源,本文提出了一种基于分时的CNN并行实现方法。上层卷积节点的计算按顺序进行,同时沿前一层的方向增加并行度,使底层并行度最大,然后在不超过20万个门的FPGA模型上实现CNN相对复杂的设计,计算速度可提高166倍。

"Wireless sensor networks (WSNs) are spatially distributed at diverse locations to monitor different physical or environmental conditions". Subject to the sensing part duty, sensors can transmit their data through the network to other nodes or to the base station. The growth of WSN applications was motivated to assist the awkward activities in military, industrial and healthcare applications. Sensors size and cost restrictions add many constraints on its performance such as energy, computational speed, "communications bandwidth" and memory. Most of the real-world engineering optimization problems represent multi-Objective problems. Objectives are often conflicting. Multi-objective optimization (MOO) is the optimization of conflicting objectives. Their solutions are set of answers that describe the best tradeoff between conflicting objectives. In this paper, a developed non-dominated sorting genetic algorithm (NSGA-II) will be proposed to address certain WSN issues. It aims to control the overlapping level between nodes via unit desk graph connectivity model. A suggested Multi-objective optimization model will also help in defining the best tradeoff between network coverage and connectivity as two competing objectives.
“无线传感器网络(wsn)在空间上分布在不同的位置,以监测不同的物理或环境条件”。在传感部分的职责下,传感器可以通过网络将其数据传输到其他节点或基站。WSN应用的增长是为了帮助军事、工业和医疗保健应用中的尴尬活动。传感器的尺寸和成本限制给其性能增加了许多限制,如能量、计算速度、“通信带宽”和内存。现实世界中大多数工程优化问题都是多目标问题。目标往往是相互冲突的。多目标优化(MOO)是对相互冲突的目标进行优化。他们的解决方案是一组描述冲突目标之间最佳权衡的答案。本文将提出一种改进的非支配排序遗传算法(NSGA-II)来解决某些无线传感器网络问题。它的目的是通过单元桌面图连接模型来控制节点之间的重叠程度。一个建议的多目标优化模型也将有助于定义网络覆盖和连接之间的最佳权衡作为两个相互竞争的目标。

Long Term Evolution (LTE) technology can provide 100 Mbps and 30 Mbps in down and upstream. Its improvement in latency and scalable bandwidth capacity depend mainly on the channel numbers and quality. Analysing the performance of LTE downlink using Environmental Protection Agency (EPA) and Extended Typical Urban (ETU) models can lead to better usage of these networks. Therefore, in this paper physical layer for downlink channel of LTE in FDD (frequency division duplexing) mode will be analysed. Where the two propagation techniques of LTE Physical Downlink Shared Channel (PDSCH) will be compare to choose the best in this paper. The simulation results show that ETU better and faster than EPA in reaching target throughput and reaching higher maximum throughput for all cases at all Doppler values.

The use of Non-Tactile Semi Cylindrical Capacitive Sensors is quite common in petroleum applications. While these devices are comparatively inexpensive and effective way of measurements in horizontal pipes, they lack the required accuracy in vertical pipes applications. The measurements have shown a drift of up to 35%, when 500 ml water is used as a test sample, due to spatial variation of the electric field inside the sensor. In order to analyse the situation, a two-dimensional mapping of the electric field and equipotential lines inside the sensor has been numerically calculated by employing finite difference method model using MATLAB programming environment. The electric field diversifies spatially across the cross-sectional area of the pipe and a non-homogeneous distribution has been shown by the results. This compromises the accuracy of semi cylindrical sensors in vertical pipes application.
非触觉半圆柱形电容式传感器在石油应用中非常普遍。虽然这些设备在水平管道中是相对便宜和有效的测量方法,但它们在垂直管道应用中缺乏所需的精度。测量结果显示,当使用500毫升水作为测试样本时,由于传感器内部电场的空间变化,漂移高达35%。为了分析这种情况,在MATLAB编程环境下,采用有限差分法模型对传感器内部的电场和等势线的二维映射进行了数值计算。结果表明,电场在管道横截面积上呈非均匀分布。这就影响了垂直管道中半圆柱形传感器的精度。

Particle swarm optimization (PSO) has become universal due to its simplicity and effectiveness in solving many problems in various applications with low computational cost. This algorithm consumes time as dealing with large tasks programs. The main goal of this paper is to introduce a parallel particle swarm optimization (PPSO) on multi-core processing kernel to decrease the determination. In order to ease transfer information among particles of shared area and exchange information by switching randomly. Most of serial PSO algorithms allow updating information among particles which takes a long time during the implementation period. The algorithm was applied to the standard optimization test set CEC (Congress on Evolutionary Computation) 2014 and gave good results compared to the previous algorithm. The empirical results show the execution time of Shared-PSO is more efficient than the serial PSO’s. The proposed algorithm using a multicore CPU technique to improve it via parallelization and enhanced the efficiency of an algorithm by increase the range of PSO application.
粒子群算法以其简单、有效、计算成本低的特点在各种应用中得到广泛应用。该算法在处理大型任务程序时消耗大量时间。本文的主要目的是在多核处理内核上引入并行粒子群优化算法(PPSO),以减少决策的确定性。为了方便共享区域内粒子间的信息传递,通过随机切换来交换信息。大多数串行粒子群算法允许粒子间的信息更新,但在实现过程中需要花费较长的时间。将该算法应用于2014年CEC (Congress on Evolutionary Computation)标准优化测试集,与之前的算法相比,取得了较好的效果。实验结果表明,共享粒子群算法的执行时间比串行粒子群算法的执行时间更短。该算法采用多核CPU技术,通过并行化对算法进行改进,并通过增加粒子群的应用范围来提高算法的效率。

Modern lives are dominated by what people see, and so there are many travel guides described wonderful places to visit. However, the sounds of these places are part of the experience. In some cases, what people hear is more important and interesting than what they see. This paper presents a new technique that gives an approach to combine map locations with their environmental sounds. It identifies places with unique sounds and encourages people to become interested in what they hear. The system is a collaborative data input, which allows public contribution in recording and archiving. Users are allowed to participate and upload their own sounds onto an efficient mapping system (Google map). The idea is to develop an audio map application; it is a great way to encourage people to gather audio and plot sounds to locations. The system is equivalent to Google Street View but with embedding audio will be Audio Street View.
