In this paper, an equivalent circuit model is proposed that describes the avalanche and snapback characteristics of Vertical Impact Ionization MOSFET (IMOS). The equivalent circuit model is constructed using MOS transistors that represent the avalanche characteristics. The main goal is to predict the vertical IMOS integrated circuits by using circuit simulations. The vertical IMOS is predicted to have a lower subthreshold slope and high ratio of current. Besides that, the equivalent circuit model is explained which is include the parasitic bipolar transistor with a generated-hole-dependent base resistance. The models for parasitic bipolar is combined with a PSPICE MOS transistor model and it is represented the gate bias dependence of snapback characteristic. The equivalent circuit parameters are extracted from the reference experimental values of previous research and modified to reproduce the measured avalanche and snapback characteristic of the vertical IMOS transistor. The results show that 90% of the analysis subthreshold slope value of circuit simulations similar to the reference experimental value. The ratio of the current also shows almost the same behavior. Therefore, the equivalent circuit model for vertical IMOS can be used in circuit simulations.
本文提出了一种描述垂直冲击电离MOSFET (IMOS)雪崩和频回特性的等效电路模型。等效电路模型是用MOS晶体管来表示雪崩特性的。主要目的是通过电路仿真来预测垂直IMOS集成电路。预测垂直IMOS具有较低的亚阈值斜率和较高的电流比。此外,还解释了等效电路模型,其中包括产生空穴依赖基极电阻的寄生双极晶体管。寄生双极模型与PSPICE MOS晶体管模型相结合,并表示了闸偏与回跳特性的依赖关系。从前人研究的参考实验值中提取等效电路参数,并对其进行修改,以再现垂直IMOS晶体管的雪崩和回吸特性。结果表明,90%的分析电路模拟的亚阈值斜率值与参考实验值相近。电流的比值也表现出几乎相同的行为。因此,垂直IMOS等效电路模型可用于电路仿真。

M. Shanmugavel, S. V. Ragavan, Hui Jean Quek, R. Gobithaasan, Abd. Rahni Mt. Piah
This paper presents preliminary investigationsinto quantification of curvature uncertainties in executing piecewise-continuous-curvature curves (PCC-Curves). ThePCC-Curves are widely used in path planning & trajectoryshaping in robotics, CAD, image processing. Dubins curve is one of such curves used in path planning. This paper investigates the difference between reference and actual velocities and their influence in curvature and in turn in final trajectories. The curvature uncertainties are measured using the uncertainties in velocity-pair. A path planning experiment using Dubins paths is conducted to quantify the difference between reference and actual velocities and curvature uncertainties. The results show the error in velocities and their distribution, and uncertainties in curvature.

Effects of Station Location and Capacity for Personal Mobility Sharing 站点位置和容量对个人出行共享的影响
K. Tomita, N. Hashimoto, M. Yokozuka, O. Matsumoto
In this study, we consider the sharing of standing-type personal mobility devices. Such devices have various advantages as a means of transportation, but their cost makes sharing more attractive than owning. Sharing personal mobility devices is expected to have social influences such as a modal shift, however, this is not yet apparent. Consideration of the effects based on a multi-agent simulation is useful, and in a previous study, we showed the preliminary results of such simulation. In this study, we extend the simulation and investigate the effects of the location and capacity of personal mobility sharing stations. The results suggest that a location change largely affects the traveling distance. Such a simulation will provide a basis for the future demand prediction and planning of personal mobility sharing.

The main purpose of this study is to develop an on-line simulation-based learning system for supporting the undergraduate students to learn linked list structures in data structures curriculum. This simulation system consists of demonstration mode, step mode, and quiz mode. In demonstration mode, the system will automatically present the operation process with its corresponding Java codes by using HTML 5.0 animation techniques. In step mode, the users can trace the process and its corresponding codes step by step. In quiz mode, the system will diagnose the learners' misconceptions and offer remedial learning suggestion. A short term self-regulated remedial learning experiment was conducted for at risk students, and the evaluation questionnaire was employed for assessing its suitability. The results reveal that the participants show high appraisal toward this system on usefulness, easiness, interest and use intention.

Local Binary Patterns for Gender Classification 性别分类的局部二元模式
Balakrishna Gudla, S. Chalamala, Santosh Kumar Jami
Gender classification using facial features has attracted researchers attention recently. Gender classification using texture features of faces exhibited promising improvement over other facial features. Gender classification finds applications in systems which use gender as one of the parameters. Local Binary Patterns (LBP) are known to have good texture representation properties. Through this paper we present a variant of Local Binary Patterns for gender classification which can discriminate the facial textures efficiently. In this method, we used a new neighborhood shape for obtaining LBP as its representation of texture is superior than traditional LBP. We compute the proposed LBP on each non-overlapping blocks of a face image and a histogram of these LBPs is computed. We used these histograms as facial feature vectors for gender classification as these histograms shown their robustness to compression and uniform intensity variations. The classification task has been achieved by using Support Vector Machine (SVM). We compared our method with existing gender classification methods based on LBP with classifier being the same as SVM. The proposed LBP based descriptor outperforms the traditional LBP based methods and achieved 96.17 percent recognition rate on combined frontal face datasets of FERET and FEI.
近年来,利用面部特征进行性别分类已成为研究领域的热点。使用面部纹理特征进行性别分类的效果优于其他面部特征。性别分类在使用性别作为参数之一的系统中得到应用。局部二值模式(LBP)具有良好的纹理表示特性。本文提出了一种基于局部二值模式的性别分类方法,可以有效地识别人脸纹理。在该方法中,我们使用了一种新的邻域形状来获得LBP,因为它对纹理的表示优于传统的LBP。我们在人脸图像的每个非重叠块上计算所提出的LBP,并计算这些LBP的直方图。我们使用这些直方图作为性别分类的面部特征向量,因为这些直方图显示了它们对压缩和均匀强度变化的鲁棒性。利用支持向量机(SVM)实现了分类任务。我们将该方法与现有的基于LBP的性别分类方法进行了比较,分类器与SVM相同。基于LBP的描述子在FERET和FEI组合的正面人脸数据集上的识别率达到96.17%,优于传统的LBP方法。

I. Burhan, A. A. Azman, S. Talib, Ahmad Azlan Ab Aziz
Multiple Outputs Programmable Integrated Circuits (MOPICs) trainer for educational applications is fabricated based on unsatisfactory usage of PIC simulation which is not able to achieve the learning outcome especially in enhancing leaner's hands-on skill through circuit designing, connection and trouble shooting. Current PIC programming is done through computer simulation, cause the leaners facing difficulty in understanding the wiring connection between the input component, PIC microcontroller and output components. The fabrication of MOPICs trainer was designed and improved by adding more output components, cost effective and user friendly. Moreover, MOPICs trainer are embedded with input component such as normally open push buttons, and 5 difference output components such as seven-segment display, servomotor, LEDs, LCD display, and 12VDC motor. Newly fabricated MOPIC trainer can be programme and re-programme for numerous tasks. Based on respondent questionnaire, it is show that on average of 92.59% agreed that newly developed MOPICs trainer is user friendly, safe and attractive to be used while 94.64% respondent agreed that there are enhancements in theoretical knowledge aspect and hands-on skill implementation in their learning process.
多输出可编程集成电路(MOPICs)培训机是基于PIC仿真的不理想使用而制作的,不能达到学习效果,特别是在通过电路设计,连接和故障排除提高学习者的动手能力方面。目前的PIC编程是通过计算机仿真来完成的,这使得学习者在理解输入元件、PIC单片机和输出元件之间的接线连接时面临困难。设计并改进了mopic教练机的制作,增加了输出元件,具有成本效益和用户友好性。此外,MOPICs教练机内嵌了常开按钮等输入元件和七段显示、伺服电机、led、LCD显示、12VDC电机等5个差分输出元件。新制造的MOPIC培训机可以为许多任务进行编程和重新编程。根据被调查者的问卷,平均有92.59%的被调查者认为新开发的MOPICs培训机是用户友好的、安全的、有吸引力的,而94.64%的被调查者认为他们在学习过程中在理论知识方面和实践技能的实施方面有了提高。

Current PIC programming is done through computer simulation, cause the leaners facing difficulty in understanding the wiring connection between the input component, PIC microcontroller and output components. The fabrication of MOPICs trainer was designed and improved by adding more output components, cost effective and user friendly. Moreover, MOPICs trainer are embedded with input component such as normally open push buttons, and 5 difference output components such as seven-segment display, servomotor, LEDs, LCD display, and 12VDC motor. Newly fabricated MOPIC trainer can be programme and re-programme for numerous tasks. Based on respondent questionnaire, it is show that on average of 92.59% agreed that newly developed MOPICs trainer is user friendly, safe and attractive to be used while 94.64% respondent agreed that there are enhancements in theoretical knowledge aspect and hands-on skill implementation in their learning process.","PeriodicalId":121874,"journal":{"name":"2015 3rd International Conference on Artificial Intelligence, Modelling and Simulation (AIMS)","volume":"262 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121225337","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}
