Classification of frontal alpha asymmetry using k-Nearest Neighbor

Frontal alpha asymmetry is used as the EEG feature in this study. Total number of 43 students participated in EEG data collections of relax and non-relax conditions. The spectral power of the alpha band for both left and right brain are extracted using data segmentations and then the Asymmetry Score (AS) is computed. Subtractive clustering is used to predetermine the number of cluster center that are presented in the data. While Fuzzy C-Means (FCM), is used to discriminate the EEG data into an appropriate cluster after the total number of cluster had been determined. The classification rate obtained from the k-Nearest Neighbor (k-NN) classifier is 84.62% which gives the highest classification rate

Experimental investigation on the feasibility and durability of a novel diesel particulate filter

The increasing concerns on fuel prices, lowest fuel consumption, higher operating efficiency and low levels of carbon monoxide and unburned hydrocarbon during cold start have generated noticeable interest on diesel engine as a prime mover with expected higher soot and NOX emissions. In order to reduce the emission from diesel fuelled vehicle, some control technologies were introduced. One of the technology is diesel particulate filter (DPF) which consists of a porous substrate that permits exhaust to pass through but traps particulate matter (PM) or carboneous soot. Conventional DPFs are manufactured using expensive materials. In this study, alternative material based on alumina and zeolite was used to form porous ceramics filter installed in diesel fuelled vehicle exhaust system and named as novel diesel particulate filter (NDPF). The NDPF elements were arranged in line with 1cm spacing inside an enclosed casing. The NDPF showed potential as DPF to curb soot emissions. Pressure drop for the NDPF was in the range of 89% - 93% at every given flow rate during pressure drop test. Effective soot reduction was in the range of 60% - 70%. As predicted, trapped soot were accumulated mostly at the front and middle of NDPF. Scanning electron microscope (SEM) and energy dispersive xray (EDX) analysis confirmed the trapping ability of carbon elements in the range of 19% - 70% for each filter. Brake specific fuel consumption (BSFC) and brake mean effective pressure (BMEP) was slightly affected when NDPF was installed in the exhaust system and resulted to drops in engine efficiency in the range of 2% - 26%. Nevertheless, further reinforcement steps for the NDPF are needed to prolong its filtering capacit

Stress analysis in steel fiber reinforced lightweight concrete wall panel with square opening using lusas / Noradila Mohd Taib

Reinforced concrete (RC) wall panel have becoming increasingly popular as load bearing structure member and Construction Industry Development Board (CIDB) play their role by introducing prefabrication technology as the method offers advantage in terms of speed of construction, better quality, easy handling and economical. Steel fiber reinforced lightweight concrete (SFR-LWC) wall panel were introduced in order to replace normal weight concrete towards benefit of reducing self-weight, overall cost of construction and most importantly sustainable. Demands for opening at wall panel are generally for doors, windows and pathway ventilation in which may create stress concentration especially at perimeter opening. In this research paper, wall panel with and without opening was model using the finite element LUSAS 14.7 software. The behavior of load bearing wall and stress concentration factor was evaluated when subjected to direct compression axial load. The model is 2000 mm wide 3000 mm high and 150 mm thick wall with 800 mm width 800 mm height and 150 mm thick size of opening. The SFR-LWC without opening (SW) showed higher ultimate load of 3911.48 kN compared to wall with opening (WO) of 1659.44 kN. The maximum compression vertical and horizontal displacements for SW were 3.43 mm and 0.454 mm respectively, meanwhile for WO was 1.96 mm and 0.031 mm respectively. Single curvature deformation profile is dominant due to applied boundary conditions of pinned at upper end and fixed at lower end. Stress concentration factor for WO is 2.91 focusing at comer. The wall panel with opening were have critical effect on the ultimate load carrying capacity, as the result shown by having opening size area of 11% from the total wall section were reduced the ultimate load carrying capacity by 56% than SW. The addition of steel fiber is superior resistance to cracking and control crack propagation of SFR-LWC as the cracks were appear when the concrete exceeded tensile strength in which stress concentration were develop

Design and development of mobile robot thematic mapping using flexible ellipse shape region

Map is used to associate the entity of normal data distribution of an environment and also be used as a reference to detect changes in monitoring application. However, there is limitation in the use of a map if the designer of a robot needs to consider its resources, such as usage of memory space. The available map has a problem in terms of rigid structure or rigid perception of robot heading and indirectly uses a lot of memory space. Therefore, a new mapping technique called flexible ellipse shape region is proposed in this study. The ellipse boundary can be changed to accommodate normal data distribution of environment and it allows perception of robot heading to be mapped to normal data distribution from 0° until 360°. The objective of this study is to design and validate a new mapping technique, called flexible ellipse shape region. The performance of the map will be compared with grid map, perception based map and flexible region map in terms of memory space, access time and accuracy of map. Number of region is used to measure memory space of different maps. Meanwhile, the access time is calculated using time complexity, while accuracy of map is measured using new technique of confidence region. The experiments were conducted using Amigobot mobile robot in an L-shaped environment equipped with sonar sensor. The robot also has to carry a light sensor and a temperature sensor. The results of the experiments have shown that flexible ellipse shape region used 0.13%, 5%, 13.04% of memory space when being compared to grid map, perception-based map and flexible region map when being mapped with non-directional sensor data. In terms of access time, flexible ellipse shape region has used less time when being compared to perception based map and flexible region map. However, flexible ellipse shape region uses more access time when being compared to grid map. Lastly, map accuracy of flexible ellipse shape region is found to be higher, which is about 55.5% when being compared to flexible region map when being mapped with non-directional sensor data

PHYSICAL PROPERTIES AND SOLUBILITY OF C02 IN BIS(2- HYDROXYETHYL)AMMONIUM ACETATE ([BHEAA]), 1-BUTYL-3- METHYLIMIDAZOLIUM TETRAFLOUROBORA TE ([BMIM] [BF 4]) AND MONOETHANOLAMINE (MEA) BASED HYBRID SOLVENTS

An industrially attractive solvent to capture COz, has been developed by incorporating the desirable properties of ionic liquids(ILs) as well as amines through mixing of the targeted ILs with amine to form hybrid solvents for the effective capture of COz. In the present work, ILs of two different families namely, bis(2- hydroxyethyl)ammonium acetate ([bheaa]) and 1-butyl-3-methylimidazolium tetraflouroborate ([bmim] [BF 4]) have been chosen to form a new binary/ ternary solvents in combination with monoethanolamine (MEA) and water for the solubility of C02. In order to establish the physical properties for the new binary [ (bheaa + water); (bheaa+ MEA); (bmimBF4+water); BmimBF4+MEA) I ternary [(bheaa + MEA + Water) (bmimBF4 + MEA + Water)] solvents, density, viscosity and refractive index measurements have been made at T = (293.15 to 353.15) K for the whole composition range. Based on the measured values the effects of temperature and concentration of individual spicies have been discussed in detail and suitable correlations have been proposed. The excess properties, namely, the excess molar volume V', viscosity deviation t'l.iJ, as well as the refractive index deviation t'l.no, have been deduced from the measured density, viscosity and refractive index values respectively for all the binary and ternary systems studied in the research. The Redlich Kister equation was used to correlate the estimated excess properties for the binary systems while the Cibulka equation was used to correlate the excess properties for the ternary systems. The COz uptake capabilities of the present developed hybrid binary ([bheaa] +water; [bheaa] +MEA; [bmimBF4] +water; [bmimBF4]+MEA) I ternary ([bheaa] +MEA+ Water, [bmimBF4] +MEA+ Water) solvents, have been made by using the SOLTEQ High Pressure Gas Solubility Cell (Model: BP-22) and the results are presented and the effect of concentration, pressure and temperature on the COz uptake have been discussed in detail. The present results indicated that the aqueous solution of [bheaa] + MEA have been found to have better C02 loading than the aqueous solution of [bmim][BF4] + MEA. The combination of these chosen ILs with selective amine solution have proved to have the characteristics for efficent C02 capture and seems to be a promising alternative for the aqueous amine solution/absorbents which are currently being used for C02 absorption

A STUDY OF THE EFFECTIVENESS OF THE PETROLEUM ENGINEERING SPECIALIZATION CURRICULUM OFFERED BY THE MECHANICAL ENGINEERING PROGRAM AT UNIVERSITY TECHNOLOGY PETRONAS

Tertiary education in Malaysia has become a subject of great importance and concern to both its people and the government. Universiti Teknologi PETRONAS, or UTP, which is wholly owned by the national oil and gas corporation PETRONAS, is one such tertiary institution <hat has emerged in response to the growing demand for higher education in the country. Under the mechanical and chemical engineering programs of UTP, undergraduate students are offered a petroleum specialization stream, for those interested in the study of petroleum or inclined to pursue a career in the oil and gas industry, which is undoubtedly one of the biggest sectors of the Malaysian economy. The motivation for offering petroleum education at UTP and the effectiveness of UTP's petroleum program and courses are the principal areas of concern of this paper. A discourse will first be presented on the progress of Malaysia's tertiary education leading to the founding of UTP, on the university's education system and its overall undergraduate engineering programme. Then, the following three aspects to the rationale for having a petroleum specialization elective at UTP are deliberated. The first aspect concerns UTP's main motivation for offering education on petroleum engineering- why petroleum engineering is taught at UTP, considering it is not a conventional field of study at the undergraduate level. The second relates to the advantages and effectiveness of offering petroleum education as a specialized stream under the mechanical engineering program', as opposed to conferring a full petroleum engineering degree. The third aspect of the issue of UTP's petroleum education discussed in this paper is the apportioning of the study of petroleum under mechanical and chemical engineering programs. The effectiveness of UTP's petroleum curriculum, in preparing its mechanical engineering graduates for the oil and gas industry, is investigated. For this, the * The scope of discussion of this paper centers on the mechanical engineering program's petroleum specialization stream. Thus, when a specific program evaluation is presented, the petroleum elective stream under chemical or civil engineering will not be discussed in this paper. MOGE Project 2002 MohJ Taib, Page 6 of 59 educational process flow within the mechanical engineering program is examined to determine the program's strength and weaknesses in preparing its students for the finalyear petroleum specialization courses. The suitability ofUTP's petroleum elective courses are also discussed, along the lines of adequacy to impart maximum benefit to students who will be embarking on a career in the petroleum industry. Due to their relevancy, monologues on the Malaysian oil and gas industry and the significance of petroleum education for the local industry are presented, to reflect on the industry's current and future requirements for skills and knowledge of its workforce. For comparison and for assessing the appropriateness of UTP' s petroleum program, this paper briefly discusses similar programs offered by other universities. In the final evaluation, issues of quality assessment and academic accreditation are delved into, capped up by a review of the strengths of UTP' s petroleum program and some recommendations for improving the program's courses

Vibriosis Vaccine Development: Pathogenesis, Immunological And Molecular Characterization Of Vibrio Alginolyticus

The aim of the research is to develop an effective vaccine against vibriosis. Vibriosis is a bacterial disease caused by Vibrio spp due to the intensive production activity of brackishwater ponds and cage-cultured fish. The pathogenicity study of V alginolyticus was performed by challenging the juvenile seabass (10±0.75 g) with 5 different isolates of V alginolyticus at different cell concentrations. All the isolates caused mortality to fish at a concentration as low as 0.2 optical density (6.28 X 103 CFU/ml). Ultrastructure changes observed by scanning and transmission electron microscopy, revealed the presence of V .alginolyticus in the gills, liver, muscle, spleen and kidney of infected fish. In addition, the V .alginolyticus cells were observed in the spleen. These pathological changes showed that V alginolyticus was responsible for the death of the infected seabass
