Data Reduction Algorithms for Wireless Sensor Networks Applications: Review 无线传感器网络应用中的数据约简算法:综述
M. Hussein
Nowadays, wireless sensor networks (WSNs) appear as an active research area due to challenging issues, including power consumption, routing algorithms, efficiency, and so on. Notwithstanding the open problems in WSN, there is already a high number of applications available. In any case for the design of any application, one of the main goals is to keep WSN as long as possible in terms of the life cycle and function. This paper discussed previous works that focused on the data reduction and routing algorithms, which aims to save energy consumption by the sensor node. Besides, it concludes the limitations in current studies and further research opportunities as well.

Enhanced Super Twisting -based RISE Control for trajectory tracking of parallel robot 基于增强超扭转的并联机器人轨迹跟踪RISE控制
Nouri Fatima, Ferguene Farid, T. Redouane
In this work, an Enhanced Super twisting-based Robust Integral of the Sign of the Error (RISE) controller is developed and is applied to control a 4 DOF Parallel Kinematic Manipulator (PKM) called – VELOCE. The proposed controller is designed by replacing the integral term of the Super Twisting Control law (STC) by a RISE control term. The main aim of the proposed controller is to benefit from the advantages of STC and RISE control method in order to improve the trajectory tracking performances. Super Twisting Control (STC) method is a powerful tool to control uncertain and nonlinear systems. Better control performances are added to the original STC thanks to RISE control method which ensures semi-global asymptotic tracking without needing the model of the manipulator. To prove the effectiveness of the proposed controller, simulations have been conducted on a 4DOF non redundant parallel manipulator called VELOCE. By comparing the original and proposed controllers, we show on simulation results the clear improvement in trajectory following performance for the proposed controller.
本文提出了一种增强型超扭转鲁棒误差符号积分(RISE)控制器,并将其应用于四自由度并联机器人velce的控制。该控制器的设计方法是将超扭转控制律(STC)的积分项替换为RISE控制项。该控制器的主要目的是利用STC和RISE控制方法的优点,以提高轨迹跟踪性能。超扭转控制(STC)方法是控制不确定非线性系统的有力工具。由于采用了RISE控制方法,使得原有的STC具有较好的控制性能,可以在不需要机械臂模型的情况下实现半全局渐近跟踪。为验证所提控制器的有效性,对四自由度无冗余并联机器人VELOCE进行了仿真。通过对原始控制器和所提控制器的比较,仿真结果表明所提控制器在轨迹跟踪性能上有明显改善。

An overview of challenges for data dissemination and routing protocols in VANETs VANETs中数据传播和路由协议的挑战概述
Mustafa Maad Hamdi, Othman Arkan Rahomi Al-Dosary, Omar Alrawi, A. Mustafa, M. Abood, Mustafa Sabah Noori
The Vehicle Ad-hoc Network (VANET) represents a developing and emerging intelligent transport technology (ITS) technology that allows interaction between vehicles (V2V) through various IEEE standards, such as IEEE 802.11p. VANET's high mobility of nodes generates major challenges when routing packets through the main target node that must be addressed with various routing protocols. Take that into consideration. In this review paper, we study three sections to describe this review. In the first section, we will explain the principle of data dissemination. In the second section, we will classification and explain the routing protocols for all their types. Finally, we will discuss the challenges for VANETs, data dissemination, and routing protocols.

Nickel-Titanium SMA Springs Actuated Bioinspired Soft Robot for Pipeline Inspections 用于管道检测的镍钛SMA弹簧仿生软机器人
Yavuz Sapmaz, S. Dilibal, Orhan Yilmaz, Ali Riza Sapmaz
Soft continuum system-based robots which can interact with different environment are becoming a novel mechatronic system in varied fields. Many soft continuum robot can easily crawl, roll, steer, and climb. These innovatively designed systems are safe, effective and easy to control. In this study, two different soft continuum robotic prototypes are developed for locomotion in pipeline inspections. The motions of these soft robots were inspired from the locomotion behavior of the caterpillar. Unlike other types of soft robotic systems, the developed soft robots do not rely on pneumatic or hydraulic actuators, but can be operated electrically using nickel-titanium (NiTi)-based shape memory alloy (SMA) springs. These soft robot systems are fabricated via casting process using silicone elastomers. The linear locomotion profile of the soft robots are investigated carefully. Prismatic and tubular forms are used for designing of the soft robots to move within the pipelines via actuation of the NiTi shape memory alloy springs. The soft body of the robot systems are made of RTV-2 grade silicone rubber due to its hyperelastic response. A thermo-mechanical training process is applied on the NiTi SMA springs for achieving the linear motion inside of the silicone-based body. A microprocessor is used for creating the locomotion sequence of the soft robotic system. The periodic optimal locomotion sequence of the soft robots is determined by means of experimental investigations.

Admission Chance Prediction Models For The School Of Physical Education And Sports Candidates 体育学院考生录取机会预测模型
Cumali Kaynar, Mustafa Mikail Özçiloğlu
Admission chance prediction helps in many ways for candidates such as estimation of results, saving time and effort for higher acceptance chance, selecting the right school and making a good training plan. Admission chance prediction is also very valuable to prepare a good training plan since the physical ability test is one of the most important criteria for admission. Among many Machine Learning approaches, we only used Support Vector Machine (SVM), Single Decision Tree (SDT). In this study, these approaches were applied to train models on the dataset of 403 candidates who applied in 2018. These models were compared to each other for better accuracy and will be used them in the following years. The results were analyzed with K-fold cross-validation to decrease data dependency and increase reliability.
预测录取机会对考生有很多帮助,比如对成绩的估计,为提高录取机会节省时间和精力,选择合适的学校,制定好的培训计划。由于体能测试是最重要的录取标准之一,因此预测录取机会对制定良好的训练计划也很有价值。在众多的机器学习方法中,我们只使用了支持向量机(SVM)、单决策树(SDT)。在本研究中,这些方法被应用于在2018年申请的403名候选人的数据集上训练模型。这些模型相互比较以获得更好的准确性,并将在接下来的几年中使用它们。结果采用K-fold交叉验证进行分析,以减少数据依赖性,提高可靠性。
