In this paper, we perform an Autonomous deep learning robot using an end-to-end system. The system operates as the controller for navigating and driving automatically. The deep learning robot used Convolution Neural Network (CNN). The CNN architecture is Mobile net with Softmax activation function. The Softmax activation function predicts the probability of steering angles. In the training phase, the CNN model learns from images and steering angles that are collected during the driving. In the testing phase, we apply the diversified environment to the trained CNN model. The CNN model accuracy is up to 85.03%. The results showed that the CNN is able to learn the diversified tasks of lanes and roads following with and without lane marking, direction planning and automatically control. Also, the CNN can replace the conventional PID controller.

This work presents a novel security technique using the optical hash function to create a message digest algorithm in the wavelength domain. The optical devices used for high speed and high security algorithm handling comprised a PANDA ring resonator connected with an add/drop filter system. The PANDA ring resonator was introduced to access the dynamic behavior of bright-bright soliton collision within the modified add/drop filter. Outputs of the dynamic states formed key suppression as a high security application for optical cryptography. The add/drop filter was an essential device in the proposed design for optical hash function processing. Simulation outputs proved that the proposed technique obtained optical hash function in the wavelength domain for real time message digest creation. The wavelength of the data must be within 40% of the center wavelength of the system input signal. The integrity of the data was maintained by this highly secure process.

In an operation, large number of surgical devices are generally used by surgeons. After they have been used, a special cleaning protocol is required to make sure that they will be disinfected and safe and to use in subsequent operations. In hospitals, the used devices will return to be treated at CSSD (Central Sterile Supply Department). The device needs to be classified and treated separately according to the types and models. Traditionally manual classification process has become an issue when the number of the returned devices increases. In this research, robotic and vision systems are used to classify the surgical devices. Object recognition and detection are developed with Machine Learning (ML) approach. Artificial Neural Networks, YOLO (You Only Look Once) algorithm, is applied to solve this problem. Five classes of surgical devices - i.e., scissor, blade holder, clamp, suction, retractor- are trained and demonstrated.

Deep learning techniques using convolutional neural networks (ConvNet) was used to detect welding defects. This technique requires a large number of input images in order to train the network. This is not practical as the defective workpieces are undesirable and often rare. This study proposes the use of synthetic images which imitate the defective spot welding characteristic as the input dataset. By replicating Heat Effected Zone Ring(HAZ), Fusion Zone Ring (FZ)and Melt Ring in different size, color, and shape, both abnormal and typical spot welding images can be generated using image processing program written in Python. These images were then used to train two different levels of classification ConvNet. The results showed that by using two thousand artificial images, the ConvNet can classify the defective spot welding at the accuracy above 98%. Finally a test set of real defective spot welding images were carried out. The outcome also yielded the similar performance.
利用卷积神经网络(ConvNet)的深度学习技术检测焊接缺陷。这种技术需要大量的输入图像来训练网络。这是不实际的,因为有缺陷的工件是不希望的,而且往往是罕见的。本研究提出使用模拟缺陷点焊特征的合成图像作为输入数据集。通过复制不同尺寸、颜色和形状的热影响区环(HAZ)、熔合区环(FZ)和熔体环(Melt Ring),利用Python编写的图像处理程序生成异常点焊图像和典型点焊图像。然后使用这些图像来训练两种不同级别的分类卷积神经网络。结果表明,利用2000张人工图像对缺陷点焊进行分类,准确率达到98%以上。最后建立了一套真实缺陷点焊图像测试集。结果也产生了类似的表现。

In the world of sound-based art installations a visual aspect of sound is often neglected. Loudspeakers come many shapes and sizes but finding the right loudspeaker can be a daunting task. Especially the venue which the installation is presented, and budgetary limitations can create many problems. Visual aspect of the design of loudspeakers can take away from the effect that the sound installation is trying to achieve. In most of the cases artists mostly interested in the sound and visual parts of the installation they created is neglected. Therefore, the loudspeakers need to be inconspicuous and unobtrusive. This paper focuses on choice of loudspeakers that will not interfere with installation itself and it is affordable enough that can be install at any venue. Through this research different types of speaker designs are investigated, and their pros and cons are compared. Commercial to do-it-yourself methods is discussed. Sound reproduction through sound exciters and their use to make different objects to become sound emitters is examined and use of such loudspeakers is advised.
在以声音为基础的艺术装置世界中,声音的视觉方面经常被忽视。扬声器有多种形状和大小,但找到合适的扬声器可能是一项艰巨的任务。尤其是展示装置的场地和预算限制会产生很多问题。扬声器设计的视觉方面可能会偏离声音装置想要达到的效果。在大多数情况下,艺术家们最感兴趣的是他们创作的装置的声音和视觉部分被忽视了。因此,扬声器需要不显眼,不引人注目。本文的重点是选择扬声器,不会干扰安装本身,它是负担得起的,可以安装在任何场所。本研究对不同类型的扬声器设计进行了研究,并对其优缺点进行了比较。讨论了商业到自己动手的方法。通过声音激发器进行声音再现,并使用它们使不同的物体成为声音发射器,并建议使用这种扬声器。

This paper proposed implementing an RF energy harvesting system with efficiency improvement by using metamaterials. The system can store the energy and supply it to a load or sensor device in the IoT system. The microstrip rectenna and metamaterial structure were implemented to improve efficiency in the energy harvesting system at 2.4 GHz. The microstrip rectenna was composed of a microstrip antenna and a rectifier circuit to converts receiving RF signal into DC voltage. Two metamaterial types were applied to the energy harvesting system: 1) the artificial magnetic conductor type which designed to be placed behind the rectenna and 2) the multiple split-ring resonators with a negative refraction index which placed in front of the rectenna. The fabricated prototypes were implemented on an RF energy harvesting system to demonstrate that the metamaterials improved the system efficiency. The measurement showed that the efficiency of the energy harvesting system was improved by using metamaterial. The electric charging time on a capacitor was measured. It was found that the electric charging time in the case of the system with AMC and MSRR structures was faster than the one without metamaterial structures.

We consider a vehicle routing problem starting from a depot to serve customers whose demands are deterministic using company vehicles. However, the capacities of their own vehicles cannot fulfill all customer demands. Thus, the company must hire vehicles with several vehicle types, each type being defined by a capacity. All company vehicles must return back to the depot, while hiring vehicles do not have to come back to the depot in order to achieve the objective of the minimum total travel distance. This mentioned characteristic of the problem are called Homogeneous Fixed Fleet Close Open Mixed Vehicle Routing Problem (HFFCOMVRP) which is an NP-Hard problem. Therefore, this research presents applying ant colony optimization which is meta-heuristic algorithms for solving complex optimization problems to find good solutions with acceptance in computation time. The algorithm presented is developed in Python and then tested against 15 standard problems of Augerat et al. (1995). The ant colony optimization with improving the solution using 2-Opt and one-move heuristics is efficient in simultaneously determining the open and close routes in the solutions with a wide range of vehicle capacities. It provides the best solution for 12 out of 15 problems
我们考虑一个车辆路线问题,从一个仓库开始,为使用公司车辆的需求确定的客户提供服务。然而,他们自己的车辆的能力并不能满足所有的客户需求。因此,公司必须租用几种类型的车辆,每种类型都由容量定义。所有公司车辆必须返回车厂,而租用车辆不必返回车厂,以达到总行驶距离最小的目标。这类问题被称为同质固定车队封闭开放混合车辆路径问题(HFFCOMVRP),属于NP-Hard问题。因此,本研究提出应用蚁群算法这一求解复杂优化问题的元启发式算法,在计算时间上寻找可接受的好解。提出的算法是用Python开发的,然后针对Augerat等人(1995)的15个标准问题进行了测试。利用2-Opt和单步启发式改进解的蚁群优化算法可以有效地同时确定大容量车辆解中的开闭路线。它为15个问题中的12个提供了最佳解决方案

However, the capacities of their own vehicles cannot fulfill all customer demands. Thus, the company must hire vehicles with several vehicle types, each type being defined by a capacity. All company vehicles must return back to the depot, while hiring vehicles do not have to come back to the depot in order to achieve the objective of the minimum total travel distance. This mentioned characteristic of the problem are called Homogeneous Fixed Fleet Close Open Mixed Vehicle Routing Problem (HFFCOMVRP) which is an NP-Hard problem. Therefore, this research presents applying ant colony optimization which is meta-heuristic algorithms for solving complex optimization problems to find good solutions with acceptance in computation time. The algorithm presented is developed in Python and then tested against 15 standard problems of Augerat et al. (1995). The ant colony optimization with improving the solution using 2-Opt and one-move heuristics is efficient in simultaneously determining the open and close routes in the solutions with a wide range of vehicle capacities.

This paper presents the development of high level synthesis tools for finite impulse response (FIR) filtering application on the embedded system. A hardware description language (HDL) is used to describe the structure and behaviour of the electronic circuits and digital logic circuits. The HDL coder is a high level synthesis tool that converts the C/C++ files into.ngc files and then to generate bitstream. MATLAB is supported with Vivado in order to generate the MATLAB programming on FPGA board. Based on the least mean square (LMS) algorithm, FIR filter is developed by MATLAB generated with the HDL coder and compatible with FPGA hardware. Then, the developed algorithm is implemented and automated the verification of HDL code on Xilinx Zedboard for FIR filtering and planning including with the cost estimation and hardware usage. Simulation implementation show that the experimental results of adaptive LMS-FIR from MATLAB and Vivado can perform well for system identification.
