Bahasa Indonesia and English have many differences in their linguistic structure. Translating sentences from one language to another is not a straight forward task for these pair of languages. Example-Based Machine Translation (EBMT) approach which introduced as a new paradigm in machine translation field is used in this initial work of developing a Bahasa Indonesia to English machine translation. The machine translation is developed by utilizing Moses system. Experiments in translating Bahasa Indonesia to English by tuning the parameters in Moses decoder have set alight about how the effects of manipulating the weight on translation model, language model, distortion (re-ordering) and word penalty on increasing the quality of the translation.

In this paper, a single-phase DC power supply based on single-phase matrix converter (SPMC) with reduced number of switches is proposed. In the proposed approach, only six switches of the typical SPMC topology are used to convert the voltage 240 Vrms (50Hz) input to a 12 VDC DC link. In the proposed topology a current control loop is used to ensure that the supply current waveform is continuous, sinusoidal and in-phase with the supply voltage resulting in high input power factor with low total harmonic distortion (THD) level. Therefore, the input currents are of a high quality and devoid of low frequency harmonics under varying load conditions, inherently. Simulation results verify the feasibility of the proposed converter.
本文提出了一种基于减少开关数的单相矩阵变换器(SPMC)的单相直流电源。在提出的方法中,仅使用典型SPMC拓扑的6个开关来将240 Vrms (50Hz)的输入电压转换为12 VDC的直流链路。在所提出的拓扑结构中,电流控制环用于确保电源电流波形连续、正弦且与电源电压同相,从而产生高输入功率因数和低总谐波失真(THD)水平。因此,在变负载条件下,输入电流具有高质量和无低频谐波的特性。仿真结果验证了该变换器的可行性。

The traditional approach for mixed-signal systems is partitioning the design at the beginning of its development cycle: digital and analog portions are then designed and verified separately. The digital design flow is typically top-down, thus allowing a continuous verification of the matching between specification and simulation results. Instead the analog flow is more frequently bottom-up and this makes hard to feedback information from the bottom level simulations to the design top level, being almost impossible SPICE simulations of the whole system (due to the excessive simulation time, convergence troubles and computational effort). This kind of mixed-signal separated flow can easily lead to a final assembly which is not sufficiently tested (such strategy cannot provide the designer with much confidence that digital and analog portions will interface correctly) and thus it's extremely difficult to debug. A full covering test strategy is not allowed also for another reason: many tests are not possible at HDL level, because of the lack of interactivity during simulation process. In fact, if we consider for example a generic calibration sequence, the procedure must assign parameter values depending on DUT state, by changing actions to perform, relating to effects of the previous acted. In this paper we propose a complete environment to test together analog and digital parts by using a semi-automatic VHDL-AMS flow adding the use of Python scripts to drive the simulation, interacting with both Verilog top-level model or real chip, creating a dynamic co-operation for real-time data processing with high re-usability for a fast conditional complete test flow.
混合信号系统的传统方法是在其开发周期开始时划分设计:然后分别设计和验证数字和模拟部分。数字设计流程通常是自上而下的,因此允许对规格和仿真结果之间的匹配进行连续验证。相反,模拟流更频繁地是自下而上的,这使得很难将信息从底层模拟反馈到设计顶层,几乎不可能对整个系统进行SPICE模拟(由于过多的模拟时间,收敛问题和计算工作量)。这种混合信号分离流很容易导致没有经过充分测试的最终组装(这种策略不能为设计师提供足够的信心,即数字和模拟部分将正确地接口),因此很难调试。不允许采用全覆盖测试策略还有另一个原因:由于在模拟过程中缺乏交互性,许多测试无法在HDL级别进行。事实上,如果我们考虑一个通用的校准序列,过程必须根据被测件的状态,通过改变要执行的动作来分配参数值,这与前一个动作的效果有关。在本文中,我们提出了一个完整的环境,通过使用半自动VHDL-AMS流来测试模拟和数字部分,并使用Python脚本来驱动仿真,与Verilog顶级模型或真实芯片进行交互,为实时数据处理创建一个动态合作,具有高可重用性,用于快速条件完整的测试流。

An improved interconnect noise methodology for reduced pessimism using dAP model 一种改进的互连噪声方法,利用dAP模型降低悲观情绪

Noise simulators were never accurate estimators of interconnect noise values as the switching pattern, slew and delay in a cluster of adjacent nets were never addressed. In modern signal integrity flows, a very high level of pessimism is incorporated into the noise methodology to augment the lack of accuracy, such as lumped aggression, noise ramps and lumped slews. Desirably, such pessimistic assumptions are much easier to compute hence efficient on simulation runtime, but often than ever it will result in an overdesigned chip. This paper discusses a recipe to reduce pessimism in interconnect noise methodologies by effectively modeling the downstream degradation on the aggression line. We will be presenting an aggression slew estimation method derived from the Elmore delay, which has less than 0.8% error compared to SPICE simulations and is inclined towards the higher slew bound when compared to both Elmore's delay and SPICE. We also show that the dAP method reduces the average reported noise by 5% even when we account for victim-aggressor reverse aggression issues.
噪声模拟器从来都不是互连噪声值的准确估计器,因为在一组相邻的网络中从来没有处理过开关模式、转换和延迟。在现代信号完整性流中,噪声方法中包含了非常高的悲观情绪,以增加准确性的缺乏,例如集总攻击,噪声斜坡和集总回转。理想情况下,这样的悲观假设更容易计算,因此在模拟运行时效率更高,但通常会导致芯片设计过度。本文通过对攻击线上的下游退化进行有效建模,讨论了一种减少互连噪声方法中的悲观情绪的方法。我们将提出一种基于Elmore延迟的攻击回转估计方法,与SPICE模拟相比,该方法的误差小于0.8%,并且与Elmore延迟和SPICE相比,该方法倾向于更高的回转界。我们还表明,即使我们考虑到受害者-攻击者的反向攻击问题,dAP方法也能将报告的平均噪音降低5%。

For the Synchronous DC-DC converter switching performance of low-voltage power MOSFETs, the gate-drain charge density (Qgd) is an important parameter. The so-called figure-of-merit, which is defined as the product of the specific on-resistance (Ron.sp) and Qgd is commonly used to quantify the switching performance for a specified off-state breakdown voltage (BVds). Two approaches are taken to reduce the Ron.sp & Qgd. First is by shrinking the trench gate width to increase the cell densities up to 645Mcell/inch2 for an ultra low on state resistance using 0.18um design rule process. The other is to obtain lower Qgd with thick bottom oxide (TBO) at minimum trench gate width by double HDP processing. The results shows that the reduce Qgd 36%, total Qg[Vgs=10V] 27% and Qg uniformity around 7% within wafer.
对于低压功率mosfet的同步DC-DC变换器开关性能来说,栅极漏极电荷密度(Qgd)是一个重要的参数。所谓的品质因数,定义为特定导通电阻(Ron.sp)和Qgd的乘积,通常用于量化特定断态击穿电压(BVds)下的开关性能。采用了两种方法来减少Ron。zh;首先是通过缩小沟槽栅极宽度,将电池密度提高到645mccell /inch2,使用0.18um设计规则工艺实现超低状态电阻。二是通过双HDP处理,在最小沟槽栅极宽度下获得较低的Qgd和厚底氧化物(TBO)。结果表明,该方法可使Qgd降低36%,总Qg[Vgs=10V]降低27%,晶圆内Qg均匀度降低7%左右。

Due to its attractive features such as high power density, long duration, high efficiency, the Brushless DC Motor (BLDCM) has gradually replaced the conventional brush DC motor and has been widely used in home appliances, office equipments, industrial applications and vehicles, etc. This paper proposes an intellectual property design of functions needed to implement a BLDCM drive, including the algorithms for commutation and control. The developed IP is verified by an Altera FPGA Board. In addition, the IP developed in this paper can be implemented as an Application Specific Integrated Circuit (ASIC) or embedded in SoC IC as a motor drive module. It is cost effective and requires shorter development time compared with the conventional microcontroller drive.

Incremental placement or Engineering Change Order (ECO) placement remains one of the most influential steps in Very Large Scale Integration (VLSI) layout design. New logic may be added into design after placement stage to meet functionality requirement. The added logic will cause design timing to become worse. In this paper, we develop an incremental placement Computer Aided Design (CAD) automation module to improve timing of the layout design. This incremental placement serves as a post-placement optimization solution that provide a cells position adjustment strategy such that no cells overlap occur and ensure no significant deviation from initial placement. Experiment is carried out by integrating the developed CAD automation module with standard industrial Electronic Design Automation (EDA) and Intel in-house design tools. Experimental results show that our approach can effectively reduce maximum and total negative slack on most of the benchmark circuits.

Transient stability analysis has become one of the major analyses in the power system to ensure the system stability to withstand a major disturbance. The effect of transient occurrence can lead to malfunction of electronic control equipment. Transient analysis can be conducted using simulation software package. One of the commercial simulation software package that used by industry worldwide is Siemens Power System Simulation for Engineering (PSS/E). This research paper highlights the usage of PSS/E to analyze Sarawak's Grid System stability using the simplest dynamic model that has been embedded into the program. To observe transient analysis using PSS/E, basic machine model such as generator, exciter and governor were used by varying default data in the program to find the best simulation output. This paper also analyzed the theory of critical clearing time (CCT) of fault occurrence between a transmission line near to the generator and far from the generator. CCT appears to be lesser when the fault occurs at a transmission line near to the generator. On the contrary, when fault occurs far from the generator, the duration of CCT is greater. The stability of the system is observed based on the machine rotor angle, machine speed, output electrical power and terminal voltage.
暂态稳定分析已成为电力系统中保证系统稳定承受大扰动的主要分析内容之一。瞬态发生的影响会导致电子控制设备的故障。利用仿真软件包进行瞬态分析。西门子电力系统工程仿真(PSS/E)是全球工业使用的商业仿真软件包之一。本研究论文强调使用PSS/E来分析沙捞越的电网系统稳定性,使用最简单的动态模型嵌入到程序中。为了观察PSS/E的暂态分析,通过改变程序中的默认数据,使用发电机、励磁机和调速器等基本机器模型来寻找最佳模拟输出。本文还分析了离发电机近和离发电机远的输电线路发生故障的临界清除时间理论。当故障发生在靠近发电机的传输线上时,CCT似乎较小。相反,当故障发生在远离发电机的地方时,CCT的持续时间更长。根据电机转子角度、电机转速、输出电功率和端电压观察系统的稳定性。

The effect of transient occurrence can lead to malfunction of electronic control equipment. Transient analysis can be conducted using simulation software package. One of the commercial simulation software package that used by industry worldwide is Siemens Power System Simulation for Engineering (PSS/E). This research paper highlights the usage of PSS/E to analyze Sarawak's Grid System stability using the simplest dynamic model that has been embedded into the program. To observe transient analysis using PSS/E, basic machine model such as generator, exciter and governor were used by varying default data in the program to find the best simulation output. This paper also analyzed the theory of critical clearing time (CCT) of fault occurrence between a transmission line near to the generator and far from the generator. CCT appears to be lesser when the fault occurs at a transmission line near to the generator. On the contrary, when fault occurs far from the generator, the duration of CCT is greater. The stability of the system is observed based on the machine rotor angle, machine speed, output electrical power and terminal voltage.","PeriodicalId":110449,"journal":{"name":"2011 IEEE Symposium on Industrial Electronics and Applications","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130758223","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}
