Determination of the Probability Plotting Position for Type I Extreme Value Distribution
Ahmad Shukri Yahaya,Norlida Md. Nor,Nor Rohashikin Mat Jali,Nor Azam Ramli
Journal of Applied Sciences , 2012,
Abstract: In this study the emphasis is placed on choosing the best plotting position used for the estimation of the parameters of the Gumbel distribution. The Type I extreme value distribution that is also known as Gumbel distribution has been used frequently to predict return periods in many engineering studies. The location parameter (μ) and scale parameter (σ) of the Gumbel distribution was estimated using the regression method. Simulation was used to obtain random variables of twenty Gumbel distributions with different location and scale parameters. The number of sample sizes chosen is 10, 20, 50, 60, 80 and 100. The sample sizes was divided into three different criteria namely small sample sizes for n = 10 and n = 20; medium sample sizes for n = 50 and n = 60 and large sample sizes for n = 80 and n = 100. This simulation study was replicated ten times. Seventeen plotting position formulae were chosen for this study namely Adamowski, Beard, Blom, Chegodayev, Cunnane, Gringorten, Hazen, Hirsch, IEC56, Landwehr, Laplace, Mc Clung, Tukey, Filliben estimator, Weibull, Gumbel and Anon. These plotting positions were used to estimate the Cumulative Distribution Function (CDF) of Gumbel Distribution. Performance measures comprising of two error measures and two accuracy measures were used to determine the best probability plotting position. It was found that different plotting positions perform well for different sample sizes. The best plotting method for small sample size is Landwehr and Hazen, for medium sample size the most suitable method is Landwehr and for large sample size the best method is the Blom method.

Abstract: Flood is the most significant natural disaster in Malaysia in terms of frequency, area extent, population affected bad damage. As a non-structural measures, flood map is very useful to be implemented mainly to prevent loss of people s lives as well as to notifying the residents of potential flood damage. This study discusses the development of flood inundation in Sungai Pulai using the XPSWMM hydrodynamic software and Geographical Information System (GIS) simulation. Floodplain mapping process includes gathering required data, hydrologic analysis, hydraulic analysis and floodplain mapping using output data sets and base maps. The results indicate that 21 flood occurrences were recorded >81 years giving the average of 3.86 or probability of 26% chance of flooding each year. About 206.433 km2 are subjected to flood inundation areas covering flood depth between 0.2-1.5 m. This study revealed for the strength and potential of a hydrological oriented XPSWMM-GIS as a tool for flood mapping.

Journal of Applied Sciences , 2009,
Abstract: The objectives of this study were to design, develop and evaluate an adaptive multimedia courseware (A-MathS) for teaching mathematics, based on learning styles. The courseware consisted of diagnostic modules and instructional modules. The diagnostic modules provided data for adaptation of instructions based on user′s learning style and knowledge level in the given topic of percentage. The instructional modules were designed based on four dominant learning styles; global-visual, global-verbal, analytical-visual and analytical-verbal. Methodology used was based on Robyler′s Instructional Design (ID) model for computer-aided instruction. Evaluation of the courseware involved usability and the effectiveness aspects. The usability study on the courseware was a case study involving thirty five Form 1 secondary school students, using the quasi-experimental pre and post-tests approach, observation, as well as survey questionnaire. Findings indicated that samples using matching A-MathS modules showed a significant rise in their post-test achievement (p = 0.000). This experimental group obtained a significant mean gain score of 10.5 compared to the low mean gain score of 1.8 for the mismatched group. Results from the study indicated that matching students′ learning styles to instructions using A-MathS multimedia courseware is effective in enhancing students′ learning gains.

Abstract: Since the last decade, globalization has significantly changed the pattern of economic activities of many developing countries including Malaysia. This economic shift has in turn brought about changes to the country s population and wealth distributions in favor of the large cities, particularly cities around Kuala Lumpur, the capital of Malaysia. The metropolitan city and its surrounding areas, by virtue of their location and other attractions, became the focus of investment of many Trans National Corporations. Expansion of industrial activities and recently service activities, to the peripheral areas has increased the level of urbanization of the region. The region is known as the Klang-Langat Metropolitan Region. The level of primacy of the metropolitan region during 2000 census as calculated using Four City Index was >71%. This pattern of polarized urbanization and economic development undoubtedly had positive implications on the country s economy. For instance, the GNP per capita for the country increased significantly from RM4,426 in 1990 to RM14,584 in 2000. This rapid economic growth mainly contributed by manufacturing and services sectors. The Klang-Langat Metropolitan Region emerged as the main player. However, such polarization of economy and urbanization can create some degree of regional imbalances. The gaps of income and other socioeconomic well beings of people in the country not only widening regionally but also ethnically. The trend now is that such a pattern of development continues to take place. These regional and racial inequalities can be major constrains for the country to achieve a long term objective of national integration.
Human Enterovirus 71 DNA Vaccine Constructs Containing 5’UTR with Complete Internal Ribosome Entry Site Sequence Stimulated Improved Anti-Human Enterovirus 71 Neutralizing Immune Responses  [PDF]

Recent improvement in the technologies for efficient delivery of DNA vaccines has renewed interest in the DNA-based vaccines. Several DNA-based vaccines against human enterovirus 71 (EV71), the causative agent for hand, foot and mouth disease (HFMD) have been developed. Here we examined the potential of improving the vaccines by inserting the EV71 5’ untranslated region (5’ UTR) containing the full length internal ribosome entry site (IRES) sequence to the EV71 VP1-based DNA vaccine constructs. Four vaccine constructs designated as 5’ UTR-VP1/EGFP, VP1/EGFP, 5’ UTR-VP1/pVAX and VP1/pVAX, were designed using the pEGFP-N1 and pVAX-1 expression vectors, respectively. Transfection of Vero cells with the vaccine constructs with the 5’-UTR
(5’-UTR-VP1/EGFP and 5’ UTR-VP1/pVAX) resulted in higher percentages of cells expressing the recombinant
protein in comparison to cells transfected with vectors without the 5’-UTR (67% and 57%, respectively). Higher
IgG responses (29%) were obtained from mice immunized with the DNA vaccine construct with the full length 5’ UTR. The same group of mice when challenged with life EV71 produced significantly higher neutralizing antibody (NAb) titers (>5-fold). These results suggest that insertion of the EV71 5’ UTR sequence consisting of the full length IRES to the EV71 DNA vaccine constructs improved the efficacy of the constructs with enhanced
elicitation of the neutralizing antibody responses.

Abstract: Equine herpesvirus-1 (EHV-1) remains one of the most common viral pathogens affecting horses worldwide presenting as a persistent infection which can establish latency in nerve ganglia (trigeminal ganglion), lymphoid tissues of the respiratory tract and peripheral blood lymphocytes. EHV-1 infection induces both humoral and cellular immune responses in horses. Virus neutralising antibody, particularly in the nasopharynx, is to kill free virus shed from infected epithelial cells. Hence this antibody has important functions in reducing virus shedding and spreading infection to cohorts. Cellular immune responses, particularly those carried out by cytotoxic T lymphocyte (CTL), have been shown to be effective in killing virus-infected cells in vitro. This review underlines the state of knowledge regarding immunity to EHV-1 and also its interaction with equine lymphocyte. Finally, the review also includes the importance of the viral immediate early (IE) protein in the pathogenesis of EHV-1. This information can be used as the basis for future research.

Abstract: This study attempts to examine the relationship between level of diversification and board ownership using bivariate correlation analysis. It further analyses using partial correlation analysis if any of the selected variables act as a common cause variable that correlates level of diversification and firm performance and develop a final estimated regression model using the selected variables extracted from 121 listed companies on the Kuala Lumpur Stock Exchanges (KLSE). Only concentration of ownership and degree of shareholders' control shows significant positive correlation. In the multiple regression analysis, dividend policy remains to be the predictor variable for Tobins' Q as a measure of firm performance but with a small R square.

Abstract: Pilihan Raya Kecil (PRK) Parlimen Bukit Gantang 2009 diadakan pada 7 April 2009 kerana kematian penyandangnya, Roslan Shaharum, daripada PAS. Pilihan raya ini dikatakan dapat dijadikan pungutan suara rakyat sama ada menerima atau sebaliknya terhadap penubuhan kerajaan baru Negeri Perak dibawah pemerintahan BN. Hasil kajian menunjukkan hampir 100 peratus responden etnik Melayu, Cina dan India menjadikan televisyen sebagai sumber utama maklumat politik mereka. Dari segi kriteria calon pula, 72.1 peratus responden Cina menyatakan mereka memilih calon yang mesra rakyat berbanding Melayu (67.9 peratus) dan India (47.9 peratus). 78.7 peratus responden Melayu, 81.6 peratus Cina dan 48.9 peratus responden India bersetuju bahawa mereka tidak merestui wakil rakyat mereka melompat parti. Persoalan mengenai krisis perlembagaan Perak memperlihatkan responden Melayu lebih cenderung menyokong Institusi Raja dan sebaliknya bagi responden Cina dan India. Merujuk kepada jangkaan kemenangan parti dalam PRK Parlimen Bukit Gantang, 27.0 peratus responden Melayu, 34.2 peratus Cina dan 57.3 peratus India menyatakan PAS akan memenangi pilihan raya tersebut berbanding BN 45.5 peratus responden Melayu, 35.5 peratus (Cina) dan 20.8 peratus (India). Ketiga-tiga kaum menyatakan Dato’ Sri Mohd. Najib Tun Haji Abdul Razak akan menjadi Perdana Menteri yang dapat menerajui pembangunan Malaysia dengan lebih inovatif dan progresif.

Abstract: This research provides evidence on the efficiency of one of the fastest developing and largest emerging securities market (Kuala Lumpur Stock Exchange, KLSE) in the Asia Pacific rim with respect to foreign investment announcements. Specifically, our study focuses on international investment announcements made in 1990 through 2000 for firms listed on the main board of the KLSE of Malaysia. The result shows that the announcements of foreign investment produce a significant positive daily abnormal return surrounding the event period. This implies that foreign investment announcements made by listed Malaysian firms do contain new relevant information which may creates market movements. At the same time, since the reaction is significantly positive, this implies that investors generally favor the international investment efforts of Malaysian firms listed at KLSE. In addition, it is also discovered that the economic development of the target country does influence the wealth creation process.

Abstract: Much research has been done and written on women. However, the same cannot be said about men. Novels, as one of the sources of corpus, are able to portray the image of Malay men which to some extent mirrors reality. The Malay culture has always looked at a man as someone who is powerful, strong, a pillar of strength for women to depend on and is always “right” in his actions. All these perceptions give the impression that the world belongs to men, alone. These images are portrayed in such genres as television, classical novels, P. Ramlee films and even popular contemporary novels. It is obvious that there has been no paradigm shift in the portrayal of men in contemporary times. Relevance theory, a theory that focuses on information processing, is able to scientifically guide readers in understanding how these images of men are being portrayed. This article looks at images of men as depicted in films and novels through a relevance theory analysis to reaffirm the above mentioned perception. Explicatures and implicatures in the messages will be explicated to help understand Malay men, in particular.
