Economic load and emission dispatch (ELED) method is playing a crucial role in power systems operation. The main objective of ELED is to schedule the committed generating units to supply power at optimum operation and minimum fossil fuel emission. In this paper, biomass energy is integrated gradually into an IEEE 30 bus test system comprising 6 generating units to reduce the conventional fuel ratio and maintain the total generated power up to seven hundred megawatts. Adding biomass as a fuel will drastically reduce the emissions from the conventional fossil fuels. The model consists of the fuel cost objective function, emission-level target produced by conventional thermal generators and the operational cost generated partially by biomass. The effectiveness of the suggested ELED model is tested on the conventional thermal generation system and the modified biomass-thermal power generation system using a modified ant lion optimization algorithm (MALO). The results of the optimized ELED biomass-using MALO are tested and validated using three different optimization techniques. These techniques are Simulated Annealing (SA), BAT and Quadratic Programming and Equal Increment Cost Criterion (QPEICC) algorithms. The results prove the effectiveness of the integrated biomass model based on MALO algorithm by minimizing the emission value, the fuel cost, and the power losses.
经济负荷排放调度方法在电力系统运行中起着至关重要的作用。排能发电的主要目标是调度发电机组,使其在最佳运行状态和最小的化石燃料排放下供电。本文将生物质能逐步集成到由6台发电机组组成的IEEE 30总线测试系统中,以降低常规燃料比,使总发电功率保持在700兆瓦。添加生物质作为燃料将大大减少传统化石燃料的排放。该模型由燃料成本目标函数、传统火力发电机组产生的排放水平目标和部分生物质发电机组产生的运行成本组成。利用改进的蚁狮优化算法(MALO)在传统热电联产系统和改进的生物质热电联产系统上验证了该模型的有效性。采用三种不同的优化技术,对利用MALO优化后的生物量进行了测试和验证。这些技术包括模拟退火(SA)、BAT、二次规划和等增量成本准则(QPEICC)算法。结果证明了基于MALO算法的生物质综合模型在最小化排放值、燃料成本和功率损失方面的有效性。

Covid-19 pandemic has been the black swan event disrupting our ordinary lives in 2020. All of us have been affected one way or another, although elderly people have been hit the hardest, meaning that they had to live with a certain degree of isolation in order to protect themselves from the disease caused by Sars-CoV-2virus. In this paper, a project for remote monitoring isolated patients is proposed, by implementing a surveillance system which senses different variables related to their own biomedical conditions, the environmental conditions of their homes and some special emergency conditions, and in turn, they are sent over to the cloud, where a monitoring team may get and process them, or otherwise, specific users may have access to them.
新冠肺炎疫情是扰乱2020年我们日常生活的黑天鹅事件。我们所有人都受到了这样或那样的影响,尽管老年人受到的打击最大,这意味着他们必须在一定程度上与世隔绝,以保护自己免受sars - cov -2病毒引起的疾病的影响。本文提出了一个远程监测隔离患者的项目,通过实施一个监测系统,该系统可以感知与患者自身生物医学条件、家庭环境条件和一些特殊紧急情况相关的不同变量,然后将它们发送到云端,在那里监测团队可以获取和处理它们,或者特定用户可以访问它们。

Advance Digital Signal Processing (DSP) techniques are controlling a wide range of signals in Smart Grid (SG) and narrowing the communication gap between various SG entities. Therefore, DSP is considered the backbone of SG that will meet future needs. The DSP interactions within SG are vital for SG reliability and efficiency. The advanced techniques for DSP interactions within SG are playing a pivotal role in improving the Power Quality (PQ). PQ includes technical challenges, such as instrumentation, measurement, and DSP techniques to increase knowledge of disturbances suffered by SG. PQ disturbances can have significantly different parameters and SG must deal with wide ranges of voltage and current magnitude disturbances, frequency drifts, and duration of disturbances. Power electronic components, such as (a) AC/DC converters, (b) adjustable-speed drives, (c) inverters, and (d) light dimmer controls the flow of power by de-shaping, flattening, or chopping sinusoidal power system voltages and currents. The aforementioned distortion of waveforms can affect PQ and create problems for nearby loads. SG ensures to operate linear and non-linear loads: (a) without damaging them, and (b) without reducing the efficiency of the power system.

A new formulation for implementing T-junction matching networks used in diplexer design is proposed in this paper. The investigation exploits the electrical length of quarter-wavelength microstrip transmission lines, and the guided-wavelength of the lines at one giga-Hertz frequency, in achieving the T-junction design formulation. This novel design would eradicate the uncertainties associated with frequent tuning and optimisation of T-junctions to achieve the desired energy distribution in diplexer designs. A prototype diplexer for separating the transmit from the receive frequencies within the front end of a wireless cellular base station is investigated and used to demonstrate the new design method. The prototype microwave diplexer with Tx and Rx centre frequencies of 2680 MHz and 3000 MHz, respectively, have been designed, implemented using microstrip, simulated, and presented. The simulation results of the circuit model and that of the microstrip layout prototype diplexer, demonstrate decent agreement with a high isolation of better than 50 dB between the transmit (Tx) and the receive (Rx) channels. The in-band lowest insertion loss is located at 1.1 dB, with a better than 20 dB in-band return loss across both the Tx and Rx bands.
本文提出了一种用于双工器设计的t结点匹配网络实现的新公式。该研究利用了四分之一波长微带传输线的电长度,以及在千兆赫频率下导线的引导波长,以实现t结设计公式。这种新颖的设计将消除与频繁调谐和优化t型结相关的不确定性,以实现双工器设计中所需的能量分布。研究了一种用于分离无线蜂窝基站前端发射和接收频率的原型双工器,并用它来演示新的设计方法。设计了Tx和Rx中心频率分别为2680 MHz和3000 MHz的微波双工器原型,并采用微带技术进行了仿真和演示。电路模型和微带布局原型双工器的仿真结果表明,发射(Tx)和接收(Rx)通道之间的高隔离度优于50 dB,具有良好的一致性。带内最低插入损耗位于1.1 dB,在Tx和Rx波段上的带内回波损耗都优于20 dB。

In Indonesia, fire safety requirement in building in Indonesia prerequisite that a building structure must able to resist fire at a certain time, which is represented by fire resistance rating. As the only one fire laboratory in Indonesia, furnaces in the laboratory are quite old and operated manually both in monitoring and controlling. This study aims to develop a monitoring system of temperatures of furnace and unexposed surface of specimen test for the fire resistance test. The developed system consists of three main parts: hardware, electronics, and software. The hardware system included sensors thermocouple type K and LM35, power supply, and a case-box. Electronics system used Arduino Mega 2560 as main microcontroller and other components such as MAX 6675, etc. Software system managed data communication between the furnace and human through graphical user interface (GUI). Writing code in Arduino was carried out using Arduino IDE while GUI was developed using Microsoft Visual Studio. The results demonstrated that the developed system was able to measure and read the temperature of both the furnace and specimen test in real time. The both measurement results could be monitored through graphical user interface (GUI), including the average values of both results. The acquisitioned data were able to convert into excel file (.xls) and stored them into memory card. Nevertheless, further development is required particularly to control the fire in furnace automatically.

This work evaluates the robustness of control systems for a quadrotor tracking a two-wheeled ground robot. To guarantee the best motion tracking and stability, a Backstepping controller is adopted for each robot. The path following approach in the quadrotor controller removes any time dependence of the problem to improve the performance in presence of uncertainties and fast motion. A real-time path of the quadrotor is planned using the potential field method to track a moving ground robot target. The motion planning system provides the quadrotor with the appropriate attractive forces as a function of the relative position and velocity of the target with respect to the quadrotor. The implementation of the proposed controllers on real robots shows smooth convergence to the path with unsaturated control signals, in addition to smaller transient error and a stronger robustness.
本工作评估了四旋翼跟踪两轮地面机器人控制系统的鲁棒性。为了保证最佳的运动跟踪和稳定性,每个机器人都采用了反步控制器。四旋翼控制器中的路径跟踪方法消除了问题的任何时间依赖性,以提高存在不确定性和快速运动的性能。利用势场法规划了四旋翼飞行器的实时路径,以跟踪地面移动机器人目标。运动规划系统为四旋翼提供适当的吸引力,作为目标相对于四旋翼的相对位置和速度的函数。该控制器在实际机器人上的实现表明,该控制器收敛到具有不饱和控制信号的路径平滑,并且具有较小的瞬态误差和较强的鲁棒性。

This paper presents a review and comparison of high-efficiency LED drivers based on single-stage flyback converters. Three different flyback designs with Continuous Conduction Mode (CCM), Discontinuous Conduction Mode (DCM) and quasi-resonant (QR) are put into consideration. The results show that unlike conventional flyback converter, which works in hard switching region, the QR flyback converter has fewer switching losses and lower electromagnetic interference (EMI) thanks to switching on the MOSFET at the valley point. For validation purposes, a 70 W QR flyback LED driver prototype is designed and tested in the laboratory. Experimental results indicate that at rated load condition, efficiency is approximately 91.3 % with Power Factor (PF) higher than 0.98, and THD lower than 7 % at universal input voltage.

User experience (UX) studies in video games have become increasingly prevalent in the literature in recent years due to an increasing global focus in UX, multiple new video game platforms and the growing utilisation of virtual reality technology. To have a video game perform at an acceptable level for the user, research scientists must investigate which parts of a video game are effective in terms of overall game enjoyment and playability. There are various factors that affect the overall user experience in a video game. In this study, we take a closer look at the differences in brain waves using an electroencephalogram (EEG) and UX satisfaction metrics in both desktop and VR gaming conditions utilising a commercial EEG device capable of measuring a range of brain activity.
近年来,由于全球越来越关注用户体验、多个新的视频游戏平台以及虚拟现实技术的日益普及,电子游戏中的用户体验(UX)研究在文献中变得越来越普遍。为了让电子游戏达到用户可接受的水平,研究人员必须调查电子游戏的哪些部分在整体游戏乐趣和可玩性方面是有效的。影响电子游戏整体用户体验的因素有很多。在这项研究中,我们使用能够测量大脑活动范围的商用EEG设备,在桌面和VR游戏条件下使用脑电图(EEG)和用户体验满意度指标来仔细研究脑电波的差异。

Web development began in the 1990s. The versatility and flexibility of this technology has made it possible for its use and application to enhance technological development in different fields of application around the world. However, in Latin American countries such as Peru, there is a lack of culturally relevant web applications applied in the socio-political field. On the other hand, since 2018 to date, many social and political movements have been making efforts to obtain perspectives and demands from citizens to promote a constituent process in Peru, efforts that to date have not achieved the expected results. In this context, the present research project aims to design and implement a Bilingual Participative Argumentation Web Platform based on a Participatory Argumentation Model in terms of Duties, Rights, Values, Policies and Facts. The methodology for the development of the web platform is WSDM (Web Semantics Design Method). The system architecture has 03 layers: View layer, Application layer and Data layer and uses the MVC (Model-Views-Controllers) as the system architecture pattern. To get a web platform culturally relevant, the API “Siminchikkunarayku” was natively integrated into the backend of the system. This web platform is considered important as a research medium because of the bilingual (Spanish/Quechua) structured corpus that will be achieved in the medium term. As a result of this phase of the research, the Bilingual Participatory Argumentation Web Platform is available on the web, which strengthens e-Participation under the Bottom-Up approach and contributes to the preservation of Quechua.
Web开发始于20世纪90年代。该技术的多功能性和灵活性使其使用和应用能够促进世界各地不同应用领域的技术发展。然而,在秘鲁等拉丁美洲国家,在社会政治领域缺乏与文化相关的网络应用程序。另一方面,自2018年以来,许多社会和政治运动一直在努力获取公民的观点和要求,以促进秘鲁的组成进程,但迄今为止尚未取得预期结果。在此背景下,本研究项目旨在设计并实现一个基于责任、权利、价值观、政策和事实四个方面的参与辩论模型的双语参与辩论网络平台。开发web平台的方法是WSDM (web语义设计方法)。系统架构分为视图层、应用层和数据层,采用MVC (Model-Views-Controllers)模式作为系统架构模式。为了使web平台与文化相关,API“Siminchikkunarayku”被本地集成到系统的后端。这个网络平台被认为是重要的研究媒介,因为双语(西班牙语/克丘亚语)结构化语料库将在中期实现。通过这一阶段的研究,双语参与式论证网络平台在网络上可用,加强了自下而上方式下的电子参与,有助于克丘亚语的保护。
