One of important part on speaker identification is the measurement of sound similarity. This study has compared two of the similarity measurement techniques in the noisy voice.First techniqueis done by using smallest vector sum of pairs and second technique is done by using frequency of occurrence of smallest vector pairs. Noise in the voice can reduce accuracy of speaker identification significantly. To overcome this problem, the two of similarity measurement was combined with Least Mean Square (LMS) for remove noise. Results of the experiments showed that the use of LMS can improve the accuracy of speaker identification at the two of similarity measurement techniques. Second technique produces better accuracy than first technique. Experimental result also showed improvement of LMS learning rate can improve the accuracy of speaker identification. © 2016, Institute of Advanced Engineering and Science. All rights reserved.


The pavement of the nailed-slab system has been proposed as an alternative solution for addressing the rigid pavement problem in soft soils. This system is used for developing a rigid pavement. The simple method of using an equivalent modulus of subgrade reaction (k') in nailed-slab system analysis was proposed by a previous researcher. This modulus consists of the modulus of subgrade reaction from a plate load test (k) and an additional modulus of subgrade reaction due to pile installing (δk). The additional modulus of subgrade reaction has been proposed by some authors. The displacement factor was used in determining the additional modulus of subgrade reaction. This factor is difficult to define. In this research, the prototype test of a nailed slab with single-pile installation was conducted to learn the validation of the theory of the additional modulus of subgrade reaction on a full-scale dimension. The prototype was constructed on soft clay, and the connection between the pile and slab was perfect monolithically. This system was loaded by centric load. A new curve of the displacement factor is proposed. Calculated deflections based on this curve were compared to the observed deflection and resulted in good agreement with the observation. Hence, it can be used in preliminary design.

Basel Convention 1989 on the control of hazardous wastes has incorporated the precautionary principle. The precautionary principle plays an important role in the area of international environmental law and governance. The use of the precautionary principle in the area of international environmental law and governance is largely in respond to the inevitability of every human being around the globe to protect environment from being polluted in their surroundings. As the Basel Convention is concerned, the Convention created an essential mechanism to protect environment from negative effects of hazardous wastes globally. Therefore, this article examines the use of the precautionary principle in the Basel Convention 1989 with relation to the international environmental law and governance by identifying actions and cases which deal with environmental protection. This article is also identifying the relation between the Basel Convention 1989 which applied the precautionary principle and Rio Declaration as a means to protect Mother Nature.

This paper reviews the use of solid polymeric electrolyte (SPE) and gel polymeric electrolyte (GPE) in photoelectrochemical cell (PEC) and dye-sensitized solar cell (DSSC). The structure of PEC and its working principle are presented. The various types of polymer electrolytes utilized in PEC and DSSC have been highlighted in this review. It also highlights the comparison of performance of PEC and DSSC utilizing those polymer electrolytes. This review is completed with the list of other SPEs that potentially be tested in DSSC. © 2014 Springer-Verlag Berlin Heidelberg.

Criminal law plays an essential role in human habitat and environment protection. The used of the criminal law in human habitat and environmental protection is largely in respond to the inevitability of every human to protect human habitat and environment from being polluted in their surrounding and habitat. Therefore this study examines the used of the criminal law with relation to the human habitat and environmental protection from the national law approach by identifying actions and cases which deal with human habitat and environmental protection. This study is also identifying the relation between the criminal law and the concept of sustainability as a means to protect human habitat and environment. © Medwell Journals, 2011.

Interest approach, which concerns with costs and benefits, would lead for environmental sustainability. This can be done through banking industry, which includes both conventional and Islamic banking. The used of the interest approach, which concerns with costs and benefits to the area of environmental sustainability, largely in response to the necessity to safeguard the environmental surrounding area. Therefore, this paper examined the use of the interest approach, which concerns with costs and benefits, which promote environmental sustainability from the environmental management perspectives; identify actions, which deal with the protection for the environment as well as a tool for the achievement in sustainable development.

Criminal law and precautionary principle hand in hand play essential roles in environmental sustainability. The used of the Criminal law and precautionary principle in environmental sustainability is largely in respond to the inevitability of every individual to protect environment from being polluted in their surroundings. Therefore, this study examines the used of the Criminal law and precautionary principle hand in hand with relation to environmental sustainability from the legal approach by identifying actions and cases which deal with environmental sustainability in order to achieve sustainable development. © Medwell Journals, 2013.

This paper proposes the utilization of extreme beamsquint technique to minimize the reflection coefficient of very small aperture radial line slot array (VSA-RLSA) antennas when the normal beamsquint technique is no longer able to do so. This technique utilizes very high beamsquint in order to obtain multiple rings on the radiating element of VSA-RLSA antennas, thus minimizes the reflection coefficient and improves the efficiency of VSA-RLSA antennas. The theoretical analysis on the generation procedure of signal reflections in the VSA-RLSA antennas, as well as the operational function of how extreme beamsquint technique can minimize the signal reflections, is explained. Various extreme beamsquint VSA-RLSA antennas and normal beamsquint VSA-RLSA antennas with radius of 75mm are designed, simulated and fabricated. The good agreement between simulation and measurement results shows that the extreme beamsquint VSA-RLSA antennas have much lower reflection coefficient response and higher efficiency than the normal beamsquint VSA-RLSA antennas. © 2012 Taylor & Francis.

This paper presents an application of Radio Frequency Identification (RFID) technology and used of e-seal in a container terminal gate in to do a clearance process. RFID and Information and Communication Technology (ICT) technologies are incorporated for the purpose of identifying prime mover driver, truck (vehicle), and number of containers used e-seal. An RFID middleware applied as to manage all the information received from Gate Checker (GC) staff and RFID reader. The used of RFID e-seal in Container Terminal Management System (CTMS), as well as RFID reader. The middleware receives information requested by GC from reader then verified by CTMS database. Both passive and active RFID tags are used in the proposed system. In order to comply with the global standard of container terminal ports, passive RFID was used for driver and vehicle tag, while e-seal, the container tag, uses active RFID. The proposed system was implemented and tested at a private Container Port in Malaysia. ICT system implementation at receiving station gate of the container terminal will reduce truck queue and manpower. The processing clearance time in conventional manual operational procedure is significantly reduced from average 300 second per container to 59 second per container. © 2016 IEEE.
