This paper evaluates three plant grow light spectra suitable for indoor planting for Spinacia Oleracea (Spinach) and Lactuca Sativa (Lettuce). Indoor plant growing chambers and three commercial plant grow lights in the Red, Red-Blue and Yellow spectral range were used. Temperature, humidity and soil moisture were recorded. The spectral range of the grow light was found to affect the temperature, humidity and soil moisture, hence also affecting plant growth. Red light was found to be more suitable for spinach and red-blue light was found to be more suitable for lettuce. A system design allowing control of the spectral range by selection of the appropriate LED's based on the plant needs using the Internet of Things was developed. Future work will implement and test this feature together with other semi-automated plant growth systems such as irrigation and light intensity.

In this work, we discuss about the design of a pyramidal horn antenna with high gain and reduced side lobes partially covering the C band and the X band of operation. The waveguide width (a), waveguide height (b), flare width (A), flare height (B) and flare length of the pyramidal antenna have been optimized. These dimensions determine the required characteristics such as S11, gain, radiation pattern of the antenna. The optimized antenna shows decent gain of approximately 12.2 dB over operating range while having a bandwidth of 3 GHz centered at the frequency of 7.5 GHz (approximately 7 GHz to 10 GHz). Ansys HFSS has been used to design and simulate the antenna. Genetic Algorithm, Quasi-Newton method and Pattern search optimization techniques are comparatively utilized to optimize the antenna design.

A new approach for ranking visual career counselling based on distance measures is explained. In this paper, the traditional method of career counselling will be carried out by means of distance consulting services to make career counselling. Especially, professional education in the capacity limitation and professional working demand for education has led to a proliferation of virtual applications. Hence, e-Visual Career Application has been developed as a web-based program for clients who have taken professional counseling efficiently. With this application, it will help clients in the process of discovering and making decisions to their interests, abilities, personalities, skills and values. This paper relies on the implications of introducing online visual career consulting in the login sessions and how it affects the people (supervisor and client), the processes (consulting), and the organizations involved.

In recent years liquid antennas have evolved as a favourable option for several use. In this paper we have tried to present a optimized cylindrical liquid antenna using Particle Swarm Optimization (PSO) algorithm and the simulation of the said antenna was done using CST. Investigation shows that generated electric field line changes the effective radius of cylinder which in turn changes the resonant frequency. So good optimization technique for proper calculation of parameters was required which will consider both the electric field line effect and designed resonant frequency. In this paper only resonant frequency is optimized and PSO has been used to calculate radius (w) and height (L) of the liquid in order to get desired result. Experiment was carried out at different frequencies by varying the parameters such as the inner radius of the cylinder, height of the liquid, and the dielectric.
近年来,液体天线已发展成为多种用途的有利选择。本文采用粒子群算法提出了一种优化的圆柱形液体天线,并用CST对该天线进行了仿真。研究表明,产生的电场线改变了圆柱体的有效半径,从而改变了谐振频率。因此,需要良好的优化技术来合理计算参数,同时考虑电场线效应和设计谐振频率。为了得到理想的结果,本文只对谐振频率进行了优化,并利用粒子群算法计算了液体的半径w和高度L。通过改变圆柱体内半径、液体高度和介质等参数,在不同频率下进行实验。

One of the latest trends in wireless technology is wearable antennas. This type of antenna needs to be flexible, lightweight and compact as they are meant to be a part of clothing and body. Properties of the textile antenna such as efficiency, input impedance, bandwidth etc. depend upon the type of substrate material used. These properties are mostly determined by the substrate dielectric constant. This paper describes the design of 2 types of rectangular microstrip patch antenna for on-body wireless communications in the 2.4GHz WLAN Band. In each design type, 3 different materials have been used as the dielectric substrate. The structure is simple, compact and easy to manufacture by using textile materials. The first design consists of three layers namely patch, substrate and ground plane. The second design consists of five layers namely superstrate, patch, substrate, ground plane and a tissue layer having properties similar to that of skin. The materials used as the substrate and superstrate for the 3 antennas are polyester, cordura and lycra. The patch and the ground plane in each of the 3 antennas have been made of copper. The simulation has been done using IE3D software. These antennas have a wide range of applications, especially in the field of healthcare.
无线技术的最新趋势之一是可穿戴天线。这种类型的天线需要灵活、轻便和紧凑,因为它们意味着成为衣服和身体的一部分。纺织天线的性能,如效率、输入阻抗、带宽等,取决于所使用的衬底材料的类型。这些性质主要由衬底介电常数决定。本文设计了两种用于2.4GHz无线局域网无线通信的矩形微带贴片天线。在每种设计类型中,使用了3种不同的材料作为介电衬底。结构简单、紧凑,易于采用纺织材料制造。第一个设计由三层组成,即贴片、基板和接地面。第二种设计由五层组成,即上覆层、贴片、衬底、地平面和具有类似皮肤特性的组织层。这3个天线的衬底和衬底材料分别是聚酯、灯芯绒和莱卡。3个天线的贴片和接地面都是铜制的。利用IE3D软件进行了仿真。这些天线具有广泛的应用,特别是在医疗保健领域。

Recently, cyber physical system (CPS) has become one of the most useful computer systems used in critical infrastructure. The CPS has been effectively applied in many areas such as power systems, transportation, and robotics. The main focus of this paper is to review integrating the physical components with cyberspaces, avoiding some security issues, and ensuring system stability. In this review, we address what the CPS is, its architecture and why security is essential. This paper introduces some issues that result because of the integration. Also, this paper will be discussing some solutions that are used to enhance the security and protection of CPS, assessing the vulnerabilities in the CPS, detecting attacks to CPS and countermeasures.

This study investigates the barriers and drivers to cloud infrastructure adoption as perceived by Information Technology Professionals. If the barriers to adoption of cloud computing technologies exist in small then the identification of these barriers will help organizations implement cloud technologies into their operating environments. This study will focus on the adoption of Infrastructure-as-a-Service technologies and not Software-as-a-Service technologies. Much of the literature on this topic revolves around security and the perception that it is less secure. While there are security issues to be addressed, many of the barriers can be overcome through an understanding of the cloud technology. A survey was conducted to measure the perception and readiness of Information Technology professionals and business decision makers. The results of the survey show that the major barriers to adoption are not always security related and that some benefits may also be found. Perceived security is found to be a significant driver for adoption of IaaS.
本研究调查了信息技术专业人员认为的云基础设施采用的障碍和驱动因素。如果采用云计算技术的障碍很小,那么识别这些障碍将有助于组织在其操作环境中实施云技术。本研究将重点关注基础设施即服务技术的采用,而不是软件即服务技术。关于这个主题的许多文献都围绕着安全性和不太安全的看法。虽然存在需要解决的安全问题,但通过理解云技术可以克服许多障碍。我们进行了一项调查,以衡量资讯科技专业人士和商业决策者的认知和准备情况。调查结果显示,采用的主要障碍并不总是与安全有关,也可能发现一些好处。可感知的安全性是采用IaaS的重要驱动因素。

In this paper, Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) based robust adaptive PI Control Scheme have been proposed and implemented on the simulated model of the non-linear benchmark processes. The servo and regulatory performance using proposed tuning methodologies were found satisfactory. The performances of the proposed control schemes have been compared with conventional adaptive PI (CA-PI) control scheme. From the extensive simulation studies, it was found that the proposed schemes implemented on non-linear processes are having better performance over CA-PI control scheme. It was also found that proposed control schemes are able to eliminate measurement noise and having good robustness features.

It was also found that proposed control schemes are able to eliminate measurement noise and having good robustness features.","PeriodicalId":269697,"journal":{"name":"2020 IEEE International IOT, Electronics and Mechatronics Conference (IEMTRONICS)","volume":"62 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134523164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computer Vision (CV) has become ubiquitous in smart systems for detecting and labeling objects, starting from social media platforms to autonomous vehicles. It requires extensive computation and image processing. In this paper, a model is processed and used to detect various colored cups with saucers from a set of different objects. The system is trained using Cascade Trainer Graphical User Interface (GUI), and the testing is done utilizing MATLAB, discussed in detail. Finally, the model is tested for its efficacy on the S32V234 Evaluation Board (EVB). Our proposed system accomplished its goal by identifying and tagging the objects of interest with maximum possible accuracy.
从社交媒体平台到自动驾驶汽车,计算机视觉(CV)在检测和标记物体的智能系统中已经无处不在。它需要大量的计算和图像处理。本文对一个模型进行处理,并用于从一组不同的物体中检测不同颜色的杯碟。利用级联训练器图形用户界面(GUI)对系统进行了训练,并利用MATLAB对系统进行了测试。最后,在S32V234评估板(EVB)上测试了该模型的有效性。我们提出的系统通过尽可能准确地识别和标记感兴趣的对象来实现其目标。
