The nature, extent and definition of a collaboration varies between individuals, disciplines, departments and institutions. It depends upon such factors as the people involved, the nature of the research problem, the research environment, the institutional culture and demographic factors. This paper will examine the concept of collaborative research and discuss its place and position in an evolving university.
Algal communities possess many attributes as biological indicators of spatial and temporal environmental changes. Algal parameters, especially the community structural and functional variables that have been used in biological monitoring programs, are highlighted in this document. Biological indicators like algae have only recently been included in water quality assessments in some areas of Malaysia. The use of algal parameters in identifying various types of water degradation is essential and complementary to other environmental indicators.
Frequency hopping spread spectrum (FHSS) systems with partial band interference require appropriate compounding of spread spectrum modulation, error correcting code, diversity and decoding method to receive improved transmission signal. In this paper, a fast FHSS system with regular low-density parity-check codes was employed to cater some anti-jamming competence by using good waterfall and error floor performance. The performance evalution of the previously mentioned system was conducted in the presence of partial band noise jamming. The best possible design of the system was achieved with the combination of diversity level L=2 with a probability rate of at 0.7 dB which showed the robustness of the system.
Comet Lulin was discovered by Lin Chi-Sheng and Ye Quanzhi using the 16-inch telescope at Lulin Observatory in Nantou, Taiwan in 2007. According to Brian Marsden of the Smithsonian Astrophysical Observatory, it reached its perihelion on 10 January 2009 at a distance of 113 million
km from the Sun. It moves in a very nearly parabolic retrograde (‘backwards’ compared to the movement of the planets) orbit at an inclination of 1.6 degrees from the ecliptic (“Newfound Comet Lulin to Grace Night Skies”). http://www.space.com/spacewatch/090206-ns-cometlulin.html). It passed nearest to the Earth at a distance of 61 million km on 23 February 2009.
This paper presents an experimental characterization of millimeter-wave (mm-wave) channels in the 6.5 GHz, 10.5 GHz, 15 GHz, 19 GHz, 28 GHz and 38 GHz frequency bands in an indoor corridor environment. More than 4,000 power delay profiles were measured across the bands using an omnidirectional transmitter antenna and a highly directional horn receiver antenna for both co- and cross-polarized antenna configurations. This paper develops a new path-loss model to account for the frequency attenuation with distance, which we term the frequency attenuation (FA) path-loss model and introduce a frequency-dependent attenuation factor. The large-scale path loss was characterized based on both new and well-known path-loss models. A general and less complex method is also proposed to estimate the cross-polarization discrimination (XPD) factor of close-in reference distance with the XPD (CIX) and ABG with the XPD (ABGX) path-loss models to avoid the computational complexity of minimum mean square error (MMSE) approach. Moreover, small-scale parameters such as root mean square (RMS) delay spread, mean excess (MN-EX) delay, dispersion factors and maximum excess (MAX-EX) delay parameters were used to characterize the multipath channel dispersion. Multiple statistical distributions for RMS delay spread were also investigated. The results show that our proposed models are simpler and more physically-based than other well-known models. The path-loss exponents for all studied models are smaller than that of the free-space model by values in the range of 0.1 to 1.4 for all measured frequencies. The RMS delay spread values varied between 0.2 ns and 13.8 ns, and the dispersion factor values were less than 1 for all measured frequencies. The exponential and Weibull probability distribution models best fit the RMS delay spread empirical distribution for all of the measured frequencies in all scenarios.
Leech infestation in otolaryngology is sporadically seen in
remote area of tropical countries, but the cases are usually not
scientifically reported. We are reporting an unusual case of a
land leech removal from external auditory canal (EAC).
The concept of the cultural construction of illness is important in terms of understanding people's behaviour. In this article, this idea is applied to psychiatric illness in Malaysia to explore how it is informed by sociocultural elements, a process that will help us understand the psychiatric expression and help-seeking behaviour of the country's population.
Rhythmically coordinating with a partner can increase pro-sociality, but pro-sociality does not appear to change in proportion to coordination success, or particular classes of coordination. Pro-social benefits may have more to do with simply coordinating in a social context than the details of the actual coordination (Cross et al., 2016). This begs the question, how stripped down can a coordination task be and still affect pro-sociality? Would it be sufficient simply to imagine coordinating with others? Imagining a social interaction can lead to many of the same effects as actual interaction (Crisp and Turner, 2009). We report the first experiments to explore whether imagined coordination affects pro-sociality similarly to actual coordination. Across two experiments and over 450 participants, mentally simulated coordination is shown to promote some, but not all, of the pro-social consequences of actual coordination. Imagined coordination significantly increased group cohesion and de-individuation, but did not consistently affect cooperation.
Improving organizational performance is the main objective of any organization. Six
Sigma is one of the most important approaches to improve performance and sustain
competitive advantage. This article reviewed the literature related to organizational
performance and explains the potential impact of Six Sigma and innovation culture on
organizational performance. Given that previous studies have reported inconclusive
results, this paper tries to establish a mechanism to explain the role of Six Sigma in
improving organizational performance. Therefore, based on the theoretical foundation
and comprehensive review of previous literature, a research framework is proposed.
This proposed framework is grounded in the implementation of Six Sigma projects; it
also establishes that innovation culture can help organizations to achieve success in a
turbulent business environment.
Pedestrians' fatality trend in road crashes has been improving in recent years though it remains third in rank behind
motorcyclists and car occupants. Based on the statistics, young pedestrians were the most affected group and the
commonest injury regions were head and legs. Pedestrian crashes occurred primarily in rural areas and straight roads
and at low light environment, and often involve cars and motorcycles. In addition to existing issues of careless and
illegal crossing practices, there are potential new hazards face by pedestrian, which are mobile electronic device use
and electric vehicle, especially when crossing roads. Road safety programs and interventions shall consider these new
Logging activity is one of the most important activities for tropical countries
including Malaysia, as it produces quality trees for papers. One of the important tree
species is the Acacia Mangium which it produces a soft tree for papermaking enterprises.
The papers are exported to Europe and countries which have high demand for paper
due to the rapid development of the printing industry. Thus we analyzed the height for
individual trees. We investigate the maximum height of the trees from 1990 to 2006
and we fit the data using extreme value model. Some of the data are missing and three
imputation methods we used to solve this problem.
Various claims have been made about the extinction of Malay Reservation Land in the country. Before
independence, the land depreciation was due to the acquisition of land by the British colonial
government for mining, opening of new villages during the communist threat and the mortgage and
sale activities by the Malay landowners to non-Malays. After independence, land depreciation linked
with the acquisition of land by the government through the Land Acquisition Act, 1960. This study is a
content analysis study involving material derived from the secondary source text and earlier research
findings. Emphasis is given to analyze the statistical size of Malay Reservation Land in the country.
Results show that the allegations regarding the depreciation trend of the Malay Reservation Land is
inaccurate and misleading. While the analysis of the size of the Malay Reservation Land found that the
actual percentage of Malay Reservation Land in 2009 was 30.13 percent instead of 11.83 percent as
claimed. The percentage grew steadily in 2013 to 31.85 percent. The analysis also found that there was
confusion about the actual size of Malay Reservation Land in the country.
Workplace deviant behavior is an action performed voluntarily by an individual and harms the
organizational norms and affects individual, organization or both. Therefore, it is a priority to the
organization to understand and look at the workplace deviant behavior issue because different
individual and environment will cause differences in how an individual behaves. Understanding the
terms, factors, typologies and effects of deviant behavior will enable organization to draw the
rehabilitation plan so deviant behavior will be curbed from the beginning. Overcoming workplace
deviant behavior will result in positive impact to the organization management and financial and will
lead to positive and conducive environment at the workplace.
In this paper, cap and pin porcelain insulator was studied under an environment with different levels
of humidity. The electric field strength and voltage distribution profile along the insulator string was
simulated using a computational software package. In this study, ANSYS Maxwell based on the Finite
Element Method (FEM) was used to simulate the short standard insulator string. The short standard
insulator string was modelled as a five-unit cap and pin porcelain insulator that was stacked according
to the IEC 60383 standard. Different humidity levels measured using relative humidity is applied to
the insulator. From this simulation, the locations within the insulator under high electric field stress are
identified when different humidity is applied.
Sustainability is an important factor in designing vernacular architecture, including vernacular palace architecture; the latter refers to low-rise buildings similar to Traditional Malay Houses (TMH). However, the Istana Lama Seri Menanti is a 4-storey mid-rise vernacular palace which was designed with sustainability in mind. This mid-rise element of the palace communicates the vernacular architecture of TMH in Negeri Sembilan whereas sustainable designs are factored in environmentally friendly materials, construction methods, and the environmental impact of the building culturally and economically. This research was aimed at examining the sustainability approach of Istana Lama Seri Menanti as a mid-rise vernacular palace in the early 20th Century, and its impact on the current generation after 109 years. The research methodologies include case and precedent studies of vernacular palaces in Malaysia as well as interviews with experts in the field. In conclusion, the architectural sustainability of Istana Lama Seri Menanti had taken into account timber availability, consumption of naturally available resources, designs with minimal environmental impact and high cultural importance in the building design with the ultimate aim of conserving it for future generations.
Prolonged drought conditions have adverse environmental and socio-economic impacts due to unmet water demands. Defining drought is difficult because of its onset and ending time. Therefore, characterisation of drought is essential for drought management operations. Thus, drought indices come in handy and are a practical approach to assimilate large amounts of data into quantitative information which can then be applied for drought forecasting, declaring drought levels, contingency planning and impact assessments. This study analyses drought events using indices, namely SPI and Deciles Index, computed with DrinC software program but are not popular in Malaysia. It is observed that both indices are identical and suitable for drought occurrences.
This paper describes the culture of Traditional Malays, in particular the use of sustainable furniture inside a Traditional Malay House (TMH). The sample houses for this study were retrieved from archived reports, from the Centre for Built Environment in the Malay World (KALAM), Universiti Teknologi Malaysia (UTM). Data collected were analysed using Componential Analysis for the presence of components (based on drawings of archival reports as well as photographic evidence from site visits). The findings showed that the Malays used a variety ofsustainable furniture in their houses. Additionally, their homes had built-in furniture, which indicated the houses were pre-designed based on its user.
Accumulation kinetic trends of cesium and cadmium in the Penaeus monodon were studied using Cs-134 and Cd-109 as a tracer. The objective of this study was to quantify the uptake and loss/depuration kinetic of these two radionuclides in the Penaeus monodon. Uptake and loss/depuration kinetic of these two radionuclides in the Penaeus monodon were varied widely, displayed a simple double kinetic model of linear and exponential trend with time unless modified by moulting at the stage in the mount cycle. Therefore, the variation of Cs-134 and Cd-109 bio-concentration factor could be concluded considerably influence by moulting cycle, environmental and biological condition as well as physico-chemical that direct effects on their uptake and loss/depuration kinetic.
Students are characterized according to their own distinct learning styles. Discovering students' learning style is significant in the educational system in order to provide adaptivity. Past researches have proposed various approaches to detect the students' learning styles. Among all, the Bayesian network has emerged as a widely used method to automatically detect students' learning styles. On the other hand, tree augmented naive Bayesian network has the ability to improve the naive Bayesian network in terms of better classification accuracy. In this paper, we evaluate the performance of the tree augmented naive Bayesian in automatically detecting students' learning style in the online learning environment. The experimental results are promising as the tree augmented naive Bayes network is shown to achieve higher detection accuracy when compared to the Bayesian network.
Dengue is the most rapidly increasing arthropodborne
disease globally. The disease burden has increased
exponentially, doubling almost every decade from the
estimated 8.3 million cases in 2010 to about 58.4 million
cases in 2013.1
The number of countries reporting
dengue has also increased. Before 1970, less than 9
countries reported dengue but now it has been reported
in more than 100 countries worldwide. It is transmitted
by two species of Aedes mosquito, Aedes aegypti and Ae.
albopictus. (Copied from article).
