This paper aims to compare the performance of Asymmetric Turbo Code and the LTE Turbo Code. The LTE Turbo Code refers to a symmetric turbo code utilizing the component codes [1 15/13] on both RSC encoders and QPP Interleaver. The component codes of asymmetric turbo code are specifically developed for the LTE frame length of 128, 256 and 752, while they are utilizing the ΩQPP Interleaver. The simulation shows that the Asymmetric Turbo Code may outperforms the LTE turbo code on the LTE frame length of 256 and 752, giving the coding gain difference 0.1 dB at BER 10-6. However, on the frame length of 128, the LTE turbo code is better than the asymmetric turbo code, giving the coding gain difference 0.3 dB.
本文旨在比较非对称Turbo码和LTE Turbo码的性能。LTE Turbo码是指在RSC编码器和QPP交织器上使用组件码[1 15/13]的对称Turbo码。不对称turbo码的分量码是专门针对LTE帧长度128、256和752而开发的,它们利用ΩQPP交织器。仿真结果表明,非对称Turbo码在LTE帧长为256和752的情况下优于LTE Turbo码,在误码率为10-6时,编码增益差为0.1 dB。然而,在帧长为128的情况下,LTE turbo码优于非对称turbo码,编码增益差0.3 dB。

A digital microfluidic system (DMFS) is realized using a surface acoustic wave (SAW) device. In this paper, the DMFS was applied to blood coagulation monitor. The DMFS used consisted of sensor plate/liquid layer/piezoelectric substrate. One pair of interdigitated electrode (IDE) was fabricated on the sensor plate. Electrical impedance change due to the blood coagulation was monitored on the IDE. For monitoring coagulation, temperature of the sample must keep at 37 °C. The liquid temperature can be controlled by the SAW. The optimum input signal condition was experimentally found and the blood coagulation was monitored. Using the DMFS, reproducible measurements of the blood coagulation were possible.

This paper proposes a RF Birdcage Coil resonator without lumped elements. The RF Birdcage Coil resonator is designed without using lumped elements, which is able to resonate at 128 MHz for non-invasively 3T Magnetic Resonance Imaging (MRI) system. This resonator has the Leg and End Rings (ERs), which are composed from copper sheets and then they are attached on the inner and the outer of a circular acrylic as a substrate material in order to produce the capacitance of the resonator and to form a suitable RF Birdcage Coil's configuration. The ERs configuration is arranged to create the capacitance at each birdcage's edge. In order to generate a resonant frequency, the ER sheets should be tuned dimensionally to change each capacitance. The Birdcage Builder software is used to design the initial capacitance configuration of the resonator. Once each capacitance value of the configuration is obtained, then the resonator is numerically simulated by using electromagnetic (EM) simulator. The simulated results show good reflection coefficient at 128 MHz with uniform magnetic field strength distribution. In addition, the birdcage coil performance is also investigated by inserting numerical hand and head phantom models into the coil. The results show that the coil with head phantom is slightly shifted to 128 MHz, in comparison with the coil without human head model, which it resonates at 128.2 MHz.
提出了一种无集总元件的射频鸟笼式线圈谐振器。RF鸟笼线圈谐振器设计时不使用集总元件,能够在128 MHz下谐振,用于非侵入性3T磁共振成像(MRI)系统。该谐振器具有腿环和端环(er),由铜片组成,然后它们连接在圆形丙烯酸的内部和外部作为衬底材料,以产生谐振器的电容并形成合适的RF鸟笼线圈的配置。在每个鸟笼的边缘布置了er配置以创建电容。为了产生谐振频率,应调整ER片的尺寸以改变每个电容。使用Birdcage Builder软件设计谐振器的初始电容配置。在得到各电容值后,利用电磁模拟器对谐振器进行数值模拟。仿真结果表明,在128 MHz处反射系数较好,磁场强度分布均匀。此外,还通过在鸟笼线圈中插入手部和头部的数值模型,研究了鸟笼线圈的性能。结果表明,与不带人头模型的线圈相比,带人头模型的线圈谐振频率为128.2 MHz,谐振频率为128 MHz。

During islanding conditions, two or more on/off GTIs will work stand alone, these inverters can't work in parallel, because there is no parallel mechanism in this inverter. So power absorption from PV not reach maximum and battery power drain. To make these inverters can work in parallel we must add a power limiter in input inverter using chopping/PWM method and this is not cheap. This research proposed method to parallel two inverter using reconfiguration of Photovoltaic (PV) circuit on microgrid based on/off GTI inverter, in islanding condition, using master slave parallel network topology inverter. The test results showed paralleling two inverter can be done using reconfiguration of Photovoltaic (PV) circuit and increase the absorption of energy from PV up to 26% and reduce the use of battery backup up to 26.38%, so the level of the battery can be sustained.
在孤岛状态下,两个或多个开/关gti将独立工作,这些逆变器不能并联工作,因为该逆变器中没有并联机构。因此,从光伏吸收的功率没有达到最大,电池的电力消耗。为了使这些逆变器可以并行工作,我们必须使用斩波/PWM方法在输入逆变器中添加功率限制器,这并不便宜。本研究提出了基于/关GTI逆变器的微网光伏(PV)电路重构并联两逆变器的方法,在孤岛条件下,采用主从并联网络拓扑逆变器。试验结果表明,通过对光伏(PV)电路的重新配置,可以实现双逆变器并联,将光伏的能量吸收提高到26%,将备用电池的使用减少到26.38%,从而维持电池的水平。

In this paper we study the effect of Hole Transport Layer NPB (N,N'-diphenyl-N,N'-bis(1-naphtyl)-1,1'-biphenyl-4,4"-diamine) and Electron Transport Layer on the performance of a single layer of Blue Organic Light Emitting Diode. Three different structures are analyzed and are compared to the reference structure. SimOLED is used to simulate and to analyze both electrical and optical characteristics. We found that the addition of 1 nm hole transport layer significantly improve the luminance by more than 1.5 times which is ascribed to the increase of the hole injection leading to the balance charge in the emissive layer. On the other hand, the application of 1 nm electron transport layer provide lower operating voltage which become more significant when both hole transport layer and electron transport layer are combined. The proposed structure reaches a luminance of 49,543 cd/m2 at 10 V.
本文研究了空穴传输层NPB (N,N′-二苯基-N,N′-双(1-萘基)-1,1′-联苯-4,4”-二胺)和电子传输层对单层蓝色有机发光二极管性能的影响。分析了三种不同的结构,并与参考结构进行了比较。SimOLED用于模拟和分析电学和光学特性。我们发现,加入1 nm空穴输运层后,发光亮度显著提高了1.5倍以上,这是由于增加了空穴注入导致发射层电荷平衡所致。另一方面,1 nm电子传输层的应用提供了更低的工作电压,当空穴传输层和电子传输层结合使用时,这种电压变得更加显著。该结构在10 V时的亮度达到49,543 cd/m2。

An implementation scheme of speech recognition over Internet called network speech recognition (NSR) can use TCP to ensure the reception of speech data on the server so that the accuracy of recognition obtained could be better. Although TCP can not guarantee the timeliness of data delivery as required by multimedia streaming applications, NSR prefer to receive the whole speech data to be recognized on the server rather than delay. In this paper, we enhance our study [1] about an analytic model of NSR recognizing a speech sent via TCP sentence by sentence by realizing and solving the model with the help of modeling tool TANGRAM-II.
网络语音识别(network speech recognition, NSR)是一种基于Internet的语音识别实现方案,它可以利用TCP协议保证服务器接收语音数据,从而提高识别的准确性。虽然TCP不能保证多媒体流应用所要求的数据传输的及时性,但NSR更愿意接收到服务器上需要识别的整个语音数据,而不是延迟。本文利用建模工具TANGRAM-II实现并求解了一个基于TCP的语音逐句识别的低噪声语音识别分析模型,从而进一步完善了我们的研究[1]。

Types of degradation modes of AlGaN/GaN high electron mobility transistors (HEMTs) in dependenc on epitaxial design and buffer quality 氮化镓/氮化镓高电子迁移率晶体管(hemt)的降解模式与外延设计和缓冲质量的关系

DC-Step-Stress tests have been applied on wafers as a fast AlGaN/GaN HEMTs robustness screening method with different epitaxial designs. The results showed three types of early degradation which are permanent and are dependent on epitaxial design and GaN buffer quality. The criterion of critical voltage is defined for the onset of degradation when a subthreshold drain current and/or gate leakage current increase significantly in a step source-drain voltage during stress test. It has been found that AlGaN/GaN HEMT devices with GaN cap show higher critical source-drain voltages as compared to non-capped devices. Devices with low Al concentration in the AlGaN barrier layer also show higher critical source-drain voltages. Superior stability and robustness performance have been achieved from devices with AlGaN backbarrier epitaxial design grown on n-type silicon carbide substrate. It is found that high electric field under the gate at the drain side is the main cause of degradation. Consequently careful epitaxial design to reduce high electric field is required. It is also shown that epitaxial buffer quality and growth process have a great impact on device robustness.
在不同外延设计的硅片上进行了直流台阶应力测试,作为一种快速筛选AlGaN/GaN HEMTs稳健性的方法。结果表明,三种类型的早期退化是永久性的,并取决于外延设计和GaN缓冲质量。临界电压的定义是在应力测试过程中,当亚阈值漏极电流和/或栅极漏极电流在阶跃源漏极电压中显著增加时开始退化。研究发现,有GaN帽的AlGaN/GaN HEMT器件比无帽器件具有更高的临界源极漏极电压。AlGaN阻挡层中Al浓度较低的器件也显示出较高的临界源漏电压。在n型碳化硅衬底上生长的AlGaN后阻挡外延设计器件具有优异的稳定性和鲁棒性。研究发现,栅极下漏极侧的强电场是导致降解的主要原因。因此,需要仔细的外延设计来减少高电场。研究还表明,外延缓冲器的质量和生长过程对器件的鲁棒性有很大的影响。

It is found that high electric field under the gate at the drain side is the main cause of degradation. Consequently careful epitaxial design to reduce high electric field is required. It is also shown that epitaxial buffer quality and growth process have a great impact on device robustness.","PeriodicalId":127270,"journal":{"name":"2015 International Conference on Quality in Research (QiR)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131595164","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}

In this research, we describe the design and manufacture of the monopole antenna for Automatic Packet Reporting System (APRS) as a payload of nanosatellite and the deployment technique of the antenna. The monopole structure made of metal ribbon rolled in a square shape, making it easy to be folded and unfolded. Satellite structure made of metal gives an advantage to the additional effect of the gain. The obtained VSWR is less than 1.5. The antenna has omnidirectional radiation pattern with HPBW 77.63° in eliptic polarization. Deployment technique has average time to deploy the antenna in 3.88 minutes. Using Global Positioning System (GPS) as a height sensor can provide the right time to activate heating circuit for cutting the nylon which deploy the antenna in the expected altitude.
本文介绍了作为纳米卫星载荷的自动分组报告系统(APRS)单极天线的设计和制造,以及天线的部署技术。单极结构的金属带卷成方形,使其易于折叠和展开。金属制成的卫星结构有利于增益的附加效应。得到的驻波比小于1.5。该天线具有全向辐射方向图,椭圆极化时HPBW为77.63°。部署技术的平均部署时间为3.88分钟。使用全球定位系统(GPS)作为高度传感器,可以提供正确的时间来激活加热电路,以切割尼龙,使天线部署在预期的高度。
