Sympathy expression model for the bystander robot in group communication 群体交流中旁观者机器人的同情表达模型
Shoji Iguchi, H. Takenouchi, Masataka Tokumaru
In this paper, we propose a sympathy expression model for a bystander robot that honors the concept of moral emotion. Therefore, we pay attention to the robot that is in a bystander position, which is unrelated to the communication between participants. We propose a sympathy expression model that lets a bystander robot learn the emotional display of others and enables cooperative expressiveness. This model allows the appropriate expressiveness affecting communication of a robot in the position of a bystander. To test it, we assume the interaction of three robots with the emotion generation model using the neural network. Further, we inspect the movement of this model by using a psychology model. As a result, we confirmed the appropriate actions of this model.
在本文中,我们提出了一个尊重道德情感概念的旁观者机器人同情表达模型。因此,我们关注的是处于旁观者位置的机器人,它与参与者之间的交流无关。我们提出了一个同情表达模型,让旁观者机器人学习他人的情感表现,并实现合作表达。这个模型允许在旁观者的位置上适当的表达影响机器人的交流。为了验证它,我们使用神经网络假设三个机器人与情感生成模型的交互。进一步,我们用一个心理学模型来检验这个模型的运动。因此,我们确认了该模型的适当动作。

Performance evaluation of direct-contact cooling tower used on thermoelectric module and parabolic trough collector for power generation 热电模块用直接接触冷却塔和发电用抛物线槽集热器的性能评价
Kenneth S. Limpahan, Rommel R. Viña, F. B. Alagao
Thermoelectric has gained attention for its clean energy generation. It has the potential of converting heat from renewable energy into direct current electricity which will replace our dependency on fossil fuels. This paper presents thermoelectric power generation system which consists of cooling tower that provides direct water cooling and solar thermal collector that provides high heat source on thermoelectric modules. Eight (8) thermoelectric modules connected in series with 40mm × 40mm × 3.5mm in size were sandwich between the absorber plate from parabolic trough collector and cooling water inside the square tube. Cooling tower thermal performance was evaluated using SolidWorks Flow Simulation software and experimental validation in steady-state and transient analysis. Experiment results show that the cooling tower has a thermal capability of lowering 100°C heated water to 28°C cold water at 2.51/min. A temperature difference of 97°C across the thermoelectric module was achieved with 28°C maintained on the cold side and 125°C on the hot side. It generated up to 21Watts at 12.7Volts. Thermoelectric technology has a significant potential for renewable and sustainable power generation especially when integrated with cooling towers for medium scale and large scale thermoelectric power generation.
热电发电以其清洁能源的发电方式而备受关注。它具有将可再生能源的热量转化为直流电的潜力,这将取代我们对化石燃料的依赖。本文介绍了一种由提供直接水冷却的冷却塔和在热电模块上提供高热源的太阳能集热器组成的热电发电系统。8个尺寸为40mm × 40mm × 3.5mm串联的热电模块夹在抛物线槽集热器吸收板与方管内冷却水之间。利用SolidWorks Flow Simulation软件对冷却塔的热工性能进行了评估,并进行了稳态和瞬态分析的实验验证。实验结果表明,该冷却塔具有以2.51/min的速度将100℃的热水降至28℃的冷水的热能力。热电模块之间的温差为97°C,其中冷侧保持28°C,热侧保持125°C。它在12.7伏电压下产生21瓦的功率。热电技术在可再生和可持续发电方面具有巨大的潜力,特别是在与冷却塔集成用于中规模和大型热电发电时。

Determination of optimum placement of the liquid metal antenna design embedded in concrete beam prototype under center — Point loading test 中心点荷载试验下混凝土梁原型内嵌液态金属天线设计最佳位置的确定
E. Fernandez, A. Carandang, J. W. Orillo, Leny Rose Quezada, I. Valenzuela, V. Yee
This study describes the application of dipole liquid metal antenna as a possible sensor of crack when embedded in a concrete beam prototype on several locations. The approach to the fabrication of antenna is based on McGyver-esque approach to microfabrication. The antenna consists of Eutectic Gallium Indium (EGaIn), a fluid metal alloy injected into microfluidic channels comprising a silicone elastomer composed of polydimethylsiloxane (PDMS). While the fluidic dipole antennas are highly flexible, stretchable, and reversibly deformable, changing its length through stretching the elastomeric channel also changes its resonant frequency. Experiments show that increasing the length of the antenna (not embedded in concrete), decreases its resonant frequency. This relationship becomes the basis of the study whether the antenna behaves in the same manner when it is already embedded in prototype concrete beams. Simultaneous testing using center-point loading machine and network analyzer for the three embedding locations of antenna are conducted to gather the necessary data that would best adapt to the inverse relationship of antenna's resonant frequency and displacement due to loading.
本研究描述了偶极子液态金属天线在混凝土梁原型中嵌入多个位置时作为裂缝传感器的应用。天线的制造方法是基于mcgyver式的微加工方法。天线由共晶镓铟(EGaIn)组成,这是一种注入微流控通道的流体金属合金,由聚二甲基硅氧烷(PDMS)组成的有机硅弹性体组成。虽然流体偶极子天线具有高度的柔性、可拉伸性和可逆变形性,但通过拉伸弹性通道来改变其长度也会改变其谐振频率。实验表明,增加天线长度(不嵌入混凝土中)会降低天线的谐振频率。这种关系成为研究天线嵌入原型混凝土梁时是否具有相同行为的基础。利用中心点加载机和网络分析仪对天线的三个嵌入位置进行同步测试,以收集最适合天线谐振频率与加载位移成反比关系的必要数据。

Jeremias A. Gonzaga, J. M. B. Biona, Byron Michael C. Omboy
This paper presents the results of the evaluations conducted on the alternative pathways considered in net energy analysis of Jatropha press-cake utilization as biofuel feedstock. Biogasification and thermal gasification are the two alternative pathways specifically being considered in this particular study. An Energy Return on Investment (EROI) was introduced in this study as the primary tool for net energy analysis respectively. EROI was able to further evaluate the economic variability and potentials of utilizing Jatropha press-cake as the feedstock for generating renewable biofuels. The by-products of the two alternative pathways being evaluated is not yet considered in this study. However it is highly recommended for future research that by-products must be considered in net energy analysis.

Path planning of underwater swarm robots using genetic algorithm 基于遗传算法的水下群机器人路径规划
Marck P. Vicmudo, E. Dadios, R. R. Vicerra
Path planning is one of the most exciting challenges in building autonomous swarm robots. It consists on finding a route from the origin of the robot to its target destination. It becomes more difficult when some obstacles are added to the environment. This paper consists of multiple obstacles: the robots and their possible path. This paper will present the path planning of underwater swarm robot based on genetic algorithm. Swarm robots will determine the position of pre-defined object and genetic algorithm generates shortest path for each robot to reach the object without collision to one another. The xyz coordinates of possible path of robot are randomly generated and they are encoded into chromosome and their fitness is defined by the summation of their displacement using Euclidian distance formula for 3-dimensional plane. The simulation results demonstrated that proposed algorithm is able to plan safe collision free paths for swarm robots. It also shown that using more population, the optimum path will be obtained. The implementation of genetic algorithm is done using computer simulation and explains the process in section two of this paper.
路径规划是构建自主群机器人最令人兴奋的挑战之一。它包括找到从机器人原点到目标目的地的路线。当环境中添加了一些障碍时,它变得更加困难。本文由多个障碍物组成:机器人和它们可能的路径。提出了一种基于遗传算法的水下群机器人路径规划方法。群体机器人将确定预定目标的位置,并通过遗传算法生成每个机器人到达目标的最短路径,而不会相互碰撞。随机生成机器人可能路径的xyz坐标,并将其编码到染色体中,利用三维平面的欧几里得距离公式将其位移之和定义其适应度。仿真结果表明,该算法能够为群机器人规划安全的无碰撞路径。结果表明,在种群数量较多的情况下,可以得到最优路径。本文第二节对遗传算法的实现进行了计算机仿真,并对实现过程进行了说明。

D. J. Mariano, J. M. B. Biona, Jeremias A. Gonzaga
Co-firing coal with biomass is one way to reduce greenhouse gas contribution from clinker production. A model was developed to determine the optimum percentage mix of rice hull for a cement plant in the Philippines that would provide the minimum life impact while ensuring product quality and economic viability. Results indicated that optimum environmental benefits is obtained at 64% rice hull thermal substitution. It is important however also to take into consideration rice hull supply limitations and system modification requirements.

J. D. dela Cruz, F. Caluyo
This study is based on the previous works conducted for the purpose of determining the Digital Terrestrial Television (DTT) coverage of National Broadcasting Network (NBN). It is also based on the results of indoor measurements conducted at 28 residential sites using live broadcast at 677 MHz. Penetration loss and path loss were investigated and a great contributor of indoor signal reduction in the four residential classifications considered, namely Class A, B, C and D. The focus of this study is to develop a statistical path loss model by measuring indoor losses caused by penetration and path loss inside residences using fixed and portable indoor antenna at 1.5m. The indoor path loss models developed for four residential classes were further calibrated for improved accuracy using heuristic approach.

J. W. Orillo, J. D. dela Cruz, Leobelle Agapito, Paul Jensen Satimbre, I. Valenzuela
In this study, digital image processing was incorporated to eliminate the Subjectiveness of manual inspection of diseases in rice plant and accurately identify the three common diseases to Philippine's farmlands: (1) Bacterial leaf blight, (2) Brown spot, and (3) Rice blast. The image processing section was built using MATLAB functions and it comprises techniques such as image enhancement, image segmentation, and feature extraction, where four features are extracted to analyze the disease: (1) fraction covered by the disease on the leaf; (2) mean values for the R, G, and B of the disease; (3) standard deviation of the R, G, and B of the disease and; (4) mean values of the H, S and V of the disease. The Backpropagation Neural Network was used in this project to enhance the accuracy and performance of the image processing. The database of the network involved 134 images of diseases and 70% of these were used for training the network, 15% for validation and 15% for testing. After the processing, the program will give the corresponding strategic options to consider with the disease detected. Overall, the program was proven 100% accurate.

Development and validation of a CFD model using ANSYS CFX for aerodynamics simulation of Magnus wind rotor blades 基于ANSYS CFX的Magnus风转子叶片空气动力学仿真CFD模型的开发与验证
Brian Kieffer Mara, B. Mercado, Luigi Andrew Mercado, J. M. Pascual, N. S. Lopez
Magnus wind turbine has become one of the emerging technologies that could harness wind power even if installed in urban areas. However, the technology has yet to reach widespread commercial use because of slow research and development. This is due to the lack of computer-based working model that could analyze and test easily all potential designs and derive which among them could significantly improve and optimize Magnus rotor blade designs. The methodology involved simulation of a parasolid model using ANSYS CFX to reproduce similar values of the reference experimental data. Inflation meshing strategies were introduced to enhance the boundary layer calculation of the model. Various turbulence models were also tested. Results showed that the first aspect ratio as the inflation layer meshing strategy and Eddy Viscosity Transport Equation turbulence model were the settings of the most favorable and well-validated working model.
Magnus风力涡轮机已经成为新兴技术之一,即使安装在城市地区也可以利用风力发电。然而,由于研发缓慢,这项技术尚未达到广泛的商业用途。这是由于缺乏基于计算机的工作模型,可以轻松地分析和测试所有可能的设计并推导出其中可以显着改进和优化Magnus转子叶片设计的设计。该方法包括使用ANSYS CFX模拟一个拟面体模型,以再现参考实验数据的相似值。引入膨胀网格策略,增强了模型的边界层计算能力。还测试了各种湍流模型。结果表明,第一展弦比作为膨胀层网格策略和涡动黏度输运方程湍流模型的设置是最有利和最有效的工作模型。

Results showed that the first aspect ratio as the inflation layer meshing strategy and Eddy Viscosity Transport Equation turbulence model were the settings of the most favorable and well-validated working model.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121779854","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}

Development of an Arduino-based automated household utility power monitoring system 基于arduino的自动化家庭公用事业电力监控系统的开发
Alan L. Vergara, Harreez M. Villaruz
This work develops an automated household utility power monitoring system and data logging in real-time. It utilizes the Arduino Uno Rev3 Microcontroller board intended for use in conjunction with the ATmega328 chip. For monitoring these parameters, it will be connected to a current transformer through the current and voltage sensor circuit. The system will convert these raw data to digital input for data acquisition and will log these to an SD card by the SD/MMC shield module for data retention in case of power failures. The system is also equipped with DS1307 serial RTC (Real-Time Clock) chip which is responsible for providing real time clock and date needed in the data logging operation. Results and findings indicated that the device has indeed successfully performed its desired function as an automated household utility power monitoring system. As such it will display in real-time, the consumed average power in watt along with its price. This will serve as an assessment parameter in order to measure the acceptability, performance relative to functionality, and marketability of the accomplished technology.
本课题开发了一个自动化的家庭公用事业电力监测系统和实时数据记录系统。它利用Arduino Uno Rev3微控制器板,用于与ATmega328芯片一起使用。为了监测这些参数,它将通过电流和电压传感器电路连接到电流互感器上。系统将这些原始数据转换为数字输入进行数据采集,并通过SD/MMC屏蔽模块将这些数据记录到SD卡上,以便在电源故障时保留数据。系统还配备了DS1307串行RTC(实时时钟)芯片,负责提供数据记录操作所需的实时时钟和日期。结果和发现表明,该装置确实成功地实现了其作为自动化家庭公用事业电力监测系统的预期功能。因此,它将实时显示,消耗的平均功率瓦特以及它的价格。这将作为评估参数,以度量完成的技术的可接受性、相对于功能的性能和可销售性。
