A STUDY OF HUMAN SKILL ACHIEVEMENT IN MALAYSIAN PUBLIC UNIVERSITIES: KNOWLEDGE, SKILL AND ATTITUDE

The principle of sustainable technical skill development is an integrated skill approach in the long terms by the instruments of science, technologies, economics and global considerations. The prospect of full implemented successfully needs a workforce which is equipped with sustainable development with related knowledge, skill and attitude (KSA). This study is related to the human skill achievement referred to the capability of technical staff in public universities. Purposely is to establish the procedures for the management and control of capital equipment. It also is to satisfy the requirements of the federal and state government and good business practices respecting control over the capital equipments. This study will be a significant endeavor for Human Resource Development (HRD) to measure the capability of human factors through KSA. The methodology of this descriptive study by searching the related topic literatures, white papers, technical papers, conference proceedings, and web-pages or even communicate to the personnel in selected public universities in Malaysia. The finding of this study will contribute to develop Overall Equipment Efficiency Model (OEEM) that could be measurable throughout to the technical skill performance among technicians in the engineering lab derived from KSA components. Therefore, human skill developments are the first competence bench marking in the capital equipment management in Malaysian public universities was identified

Influence of Eu3+ dopant on physical and optical properties of lithium-borosulfophosphate glasses

Multi-components glass host with enhanced physical and optical features are greatly demanding for various photonics and optoelectronics devices. Selection of suitable glass former, modifier, and dopant ions with optimized composition is a key concern in the fabrication of novel optical glass materials for the aforementioned purpose. Thus, this work reports the convectional melt quench synthesis of europium (Eu3+) doped lithiumborosufophosphate glasses with composition 15Li2O-30B2O3-15SO3-(40-)P2O5-Eu2O3 (where = 0.1, 0.3, 0.5, 0.7 and 1.0 in mol%). The effect of P2O5 substitution by Eu2O3 on their physical (density, molar volume, ion concentration, polaron radius, inter-nuclear distance and field strength) and optical properties was examined. The amorphous nature of the samples was confirmed by XRD diffraction pattern. The density of glass samples was slightly increased with increasing concentration of Eu2O3. Such trend is attributed to the higher molecular weight of Eu2O3 (351.926 g/mol) than P2O5 (141.9445 g/mol). The room temperature absorption spectra revealed four weak bands in the UV-Vis range and two strong bands in the NIR range with 1.0 mol% glass sample possessing the highest intensity at 7F0→7F6 (2095 nm). Incorporation of Eu3+ ion significantly enhanced the glass absorbance and the physical properties. The results on high refractive index (~2.3), polarizability and non-linear physical features suggest that these glasses are potential for photonics and solid-state laser applications.Keywords: Borosulfophosphate glasses, Europium ions, physical properties, optical properties and photoluminescenc

Canonical surfaces associated with projectors in Grassmannian sigma models

We discuss the construction of higher-dimensional surfaces based on the harmonic maps of S2 into PN−1 and other Grassmannians. We show that there are two ways of implementing this procedure—both based on the use of the relevant projectors. We study various properties of such projectors and show that the Gaussian curvature of these surfaces, in general, is not constant. We look in detail at the surfaces corresponding to the Veronese sequence of such maps and show that for all of them this curvature is constant but its value depends on which mapping is used in the construction of the surface

Synthesis of Fused Heterocyclic Derivatives from 5-Ethyl-3-Hydrazino-5H-1,2,4-Triazino[5,6-b]Indole

5-Ethyl-3-hydrazino-5H-1,2,4-triazino[5,6-b ]indole II was used for the synthesis of various heterocyclic derivatives. This was performed by reaction of its 3-hydrazino group with different reagents such as acid anhydrides, ethylacetate, diethyl oxalate, thioglycolic acid, aroyl esters and acid chlorides. The structure of the products was confirmed by different spectroscopic and analytical methods

A convenient criterion under which Z_2-graded operators are Hamiltonian

We formulate a simple and convenient criterion under which skew-adjoint Z_2-graded total differential operators are Hamiltonian, provided that their images are closed under commutation in the Lie algebras of evolutionary vector fields on the infinite jet spaces for vector bundles over smooth manifolds.Comment: J.Phys.Conf.Ser.: Mathematical and Physical Aspects of Symmetry.

Production of bioethanol by direct bioconversion of oil-palm industrial effluent in a stirred-tank bioreactor

The purpose of this study was to evaluate the feasibility of producing bioethanol from palm-oil mill effluent generated by the oil-palm industries through direct bioconversion process. The bioethanol production was carried out through the treatment of compatible mixed cultures such as Thrichoderma harzianum, Phanerochaete chrysosporium, Mucor hiemalis, and yeast, Saccharomyces cerevisiae. Simultaneous inoculation of T. harzianum and S. cerevisiae was found to be the mixed culture that yielded the highest ethanol production (4% v/v or 31.6 g/l). Statistical optimization was carried out to determine the operating conditions of the stirred-tank bioreactor for maximum bioethanol production by a two-level fractional factorial design with a single central point. The factors involved were oxygen saturation level (pO2%), temperature, and pH. A polynomial regression model was developed using the experimental data including the linear,quadratic, and interaction effects. Statistical analysis showed that the maximum ethanol production of 4.6% (v/v) or 36.3 g/l was achieved at a temperature of 32�C, pH of 6, and pO2 of 30%. The results of the model validation test under the developed optimum process conditions indicated that the maximum production was increased from 4.6% (v/v) to 6.5% (v/v) or 51.3 g/l with 89.1% chemicaloxygen-demand removal

An improved load shedding scheduling strategy for solving power supply defisit

When high electricity demand growth not matched by the growth in generating capacity, energy deficit problem cannot be avoided. Power outages of up to 6 hours per day are part of the power crisis experienced by electricity consumers in Sumatra. The utility has applied load shedding approach to tackle the problem, however, there are weaknesses on the current load shedding program. It is discovered that most of the power outage occurs randomly without any prior notice and sometime lasted for many hours. Load shedding program is not properly scheduled and not fairly distributed among all consumers. A proper scheduling program must have a clear periodic schedule, fixed outage hours, fairly distributed and alternated among consumers and most importantly solve energy deficit problem. This paper presented an improved load shedding scheduling strategy based on Round Robin method. The method is then illustrated and applied on actual daily load profile of Sumatra electrical system

REDUCING DISTRIBUTED URLS CRAWLING TIME : A COMPARISON OF GUIDS AND IDS

Web crawler visits websites for the purpose of indexing. The dynamic nature of today’s web makes the crawling process harder than before as web contents are continuously updated. In addition, crawling speed is important considering tsunami of big data that need to be indexed among competitive search engines. This research project is aimed to provide survey of current problems in distributed web crawlers. It then investigate the best crawling speed between dynamic globally unique identifiers (GUIDs) and the traditional static identifiers (IDs). Experiment are done by implementing Arachnot.net web crawlers to index up to 20000 locally generated URLs using both techniques. The results shown that URLs crawling time can be reduced up to 7% by using GUIDs technique instead of using IDs
