In the design process, the filter length, pass band and stop band frequencies, feasible pass band and stop band ripple sizes are specified. FIR filter design is a multi-modal optimization problem. The conventional gradient based optimization techniques are not efficient for digital filter design. An iterative method is introduced to find the optimal solution of FIR filter design problem. Genetic algorithm (GA), particle swarm optimization (PSO), improved particle swarm optimization (IPSO) has been used here for the design of linear phase low pass FIR filter. IPSO is an improved PSO that proposes a new definition for the velocity vector and swarm updating and hence the solution quality is improved. A comparison of simulation results reveals the optimization efficacy of the algorithm over the prevailing optimization techniques for the solution of the multimodal, non-differentiable, highly non-linear, and constrained filter design problems.","PeriodicalId":383828,"journal":{"name":"2011 IEEE Student Conference on Research and Development","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127420109","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}

However, the main drawback of this logic is the non implementation of inverted logic. To implement the inverted logic, it is required to duplicate the logic circuit up to that part with inverted inputs. This obviously results the increase in area, delay as well as the power dissipation of the circuit. On the other hand, it is very simple to realize the circuit with both the inverted and non-inverted logic using static CMOS implementation. In this paper, this problem is addressed with the realization of the circuit which requires the implementation of inverted logic using mixed static and domino logic. To show the efficiency of the proposed model, a simple example like implementation of high fan-in NAND gate cascaded with AND gate is considered. With the comparison of all the three logics with a fixed fan-in of 7, 8 and 9 for both the gates, on an average 69.7% improvement is achieved in Power Delay Product (PDP), 11.4% improvement in area in terms of transistors using mixed logic implementation over static logic implementation and 68.64% improvement in PDP and 28.4% improvement in area over dynamic CMOS implementation when designed in 180nm technology.","PeriodicalId":383828,"journal":{"name":"2011 IEEE Student Conference on Research and Development","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114957088","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}

Therefore, many studies have been done to support the demand of the monitoring system and the current trend was focusing on the optical behavior of the lubricant by using spectrometer. In our research work, UV/VIS Spectrometer was employed to analyze the optical behavior of lubricant and the relation with real parameter of lubricant such as oxidation, Total Acid Number (TAN) and contamination. The sample of used transmission oil was taken in real time and based on different mileage. With the combination of spectroscopy method and statistical analysis, the main parameters in lubricant monitoring properties including TAN and contamination can be determined quantitatively.

A Coordinated Voltage Control (CVC) approach that consists of primary voltage control (PVR), secondary voltage control (SVR) and tertiary voltage control (TVR) is the most effective solutions for reactive power and voltage control. CVC refers to an approach in which secondary voltage control or regulations (SVR) is carried out automatically using a control system that would coordinate the various voltage control equipment to achieve a desired voltage at a pilot node in the system. There are various SVR model has been deployed by power utility for their CVC implementation. In Tenaga Nasional Berhad (TNB) power system, coordinated voltage control system is yet to be implemented, but improvement in the approach and methods to performing secondary voltage control are desirable since it could enhance system performance in terms of reliability and security as well as system losses. To demonstrate the capabilities of SVR within TNB grid system, a preliminary studies has been carried out, where new SVR dynamic model has been developed suitable for TNB CVC system implementation. Since voltage control is a real time activity that repeats itself on a daily basis, it was agreed that a more effective approach to study the process of SVR would be to perform simulations on a 24-hour basis where at defined times during the day the SVR would be applied. Two simulations approach has been carried: 24-hour load flow and 24-hour dynamic simulation, both implemented using PSS/E simulation software. From studies conducted, it is clear that implementation of SVR system can bring great potential and benefits to TNB in-term of system loss reduction, better voltage profile, and control and effective utilization of reactive power resources.","PeriodicalId":383828,"journal":{"name":"2011 IEEE Student Conference on Research and Development","volume":"5 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127993915","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}
