Abstract:

For every five years, the Faculty of Engineering and Built Environment in Universiti Kebangsaan Malaysia, a public university in Malaysia will update the structure of the undergraduate education curriculum in order to improve and enhance its teaching and learning methods. One important feature of this effort is the result of updating the mapping of the course outcome, the programme outcome and the level of Bloom Taxanomy. In this study, the achievements of the course outcome, prograame outcome and Bloom Taxanomy for Vector Calculus subject for semester 1 session 2015 / 2016 were assessed using the pre-final method. The pre-final test was conducted in the 14th week of the semester. A total number of five questions were given provided that each measures the level of understanding of Bloom Taxanomy from level 1 (knowlwdge) to stage 6 (creation). A total of 42 first year students from the departments of Electrical, Electronic and System Engineering programs participated in the pre-final test results were analyzed using the Reasch measurement model. The study found that all the questions fulfill the real purpose of the assessment. The conclusion of the study is that the pre-assessment of the achievement of both the course outcome and programme outcome should be made to ensure that the assessment tool for course outcome and programme outcome, in this case the exam questions, really evaluates what needs to be assessed.

Abstract:

Implementation of foundations in the rammed pits allows to provide the construction of buildings on soft loess and subsidence soils, as well as on clay and loam grounds. Principle of the proposed pit ramming under foundation consists in the fact that a weight of 2.5-15 tons drops from a height of 6-12 m in a same spot. As a result of soil compaction the hollow is formed, in which the reinforcing rebar skeleton is installed and concrete is poured. Foundation in rammed pit, which created in this way, can hold the bearing capacity of up to 10,000 kN. Machineries based on the tractor, the crane-excavator or the ramming machine are used for pit ramming under the foundation. The main strike element is the rammer that falls under its own weight along the guiding rail trunk or the guiding rail road. Using of such machineries and foundation implementation in rammed pit can significantly reduce the volume of excavation work, material consumption and the complexity of implementation. Pit ramming in the soil with water-saturated layer (aquifer) is associated with some technical difficulties. The softened soil collapses into the pit bottom. Water at the pit bottom contributes to the creation of vacuum, during the removal of rammer, which generates the effect of its suction. It makes the pit ramming without any special measures quite problematic. And at the same time it is necessary to prevent the entry of water into the pit cavity for foundation implementation in the soils with water-saturated layer. A way to successfully cross the water-saturated layer and to implement the foundations in rammed pits is proposed. The developed technology has been repeatedly tested in the constructions of industrial and livestock buildings.

Abstract:

Thermal treatment (TT) of concrete can significantly accelerate the strength growth during cast-in-situ construction. Forecasting the compressive strength of thermal treated self-compacting concrete (SCC) is one of the pillars of the technical safety of buildings. To this end we carried out a study of strength development issue of SCC during TT. For our study, we used SCC of grade C25. Test samples were cured with TT by infrared radiators for 7, 9, 11, 13, 16 and 24 hours. Then warmed samples were tested for compressive strength after 0.5, 4, 12 and 24 hours of cooling period. Study was carried out on the basis of analyzing, generalizing and evaluations of experimental data. A mathematical model for determining the compressive strength of SCC after one day of curing of SCC with TT is proposed, which allows to forecast the concrete behavior in a real cast-in-situ construction of SCC structures immediately after one day of curing with TT. This paper also presents a technology of TT of structures for cast-in-situ construction with SCC. The proposed technology can be used for mass cast-in-situ construction. Application of this technology allows to reduce the turnover of formwork, the labor costs for construction, and the construction period.

Abstract:

Waterproof plywood as product of the wood reprocessing has the number of advantages for civil engineering, such as: ability to form curved surface; transportability and possibility of quick erection; relatively large size and similar physical-mechanical properties in lengthwise and crosswise direction; resistance against chemical and biological influence. Bakelite plywood is one of the prospective types of waterproof plywood. The effective introduction of bakelite plywood into civil engineering slows down because of insufficient knowledge of influence of the range of factors on strength and deformability of the bakelite plywood structures. Taking into account the above, the research work is devoted to study physical-mechanical properties of bakelite plywood as orthotropic material. The aim of the research is to obtain the results, which can be used for design of the bakelite plywood structures. Samples with size 30x30x120 mm, made by bonding the required number of 9-layers plywood sheets with the use of phenol-formaldehyde glue, were used to determine mechanical-physical characteristics of bakelite plywood. The sheets with thickness of 10 mm were used in the research work. Every sample was tested by sixfold loading and unloading with measurement of deformations in the process of loading. The research results of physical-mechanical properties of bakelite plywood as orthotropic material are shown in the article. They are necessary for practical calculations of tensions in the adhesive joints by methods of elastic theory of anisotropic materials. The possibility of using the obtained research results for practical calculations is shown on the example of the overlapping adhesive joint.

Abstract:

One of the main guarantees of sustainable development of the civilization nowadays is settlement of the energy problem. People will encounter the crisis, connected with the reduction of the modern rate of production due to the depletion of fossil fuels without introduction of energy-saving technologies and renewable energy resources. The research work is devoted to reduction of the fossil fuels consumption in manufacturing of concrete elements and replacement them by solar energy, which can be used for heat treatment of concrete. Transformation to the renewable energy resources is associated with economic costs, which seem unjustified without taking into account its social and ecological aspects. The aim of the research work is to develop the methodic of economic assessment of the solar energy use for the manufacturing of concrete elements, taking into account its social and ecological advantages. The developed methodic includes equitation for determination: of the cost of yearly saving of fuel and energy resources during operation of solar energy equipment; the nonrecurring cost of production and installation of the solar energy equipment; ecologic and social components of the converted economic costs. The economic assessment shows that yearly replacement of fossil fuels by solar energy is 40-60% in dependence on the geographic area of manufacturing of concrete elements. The yearly economic benefit from replacement of fossil fuels is 60-85 tons of oil equivalent for the plants with manufacturing capacity of 20000 m3, 150-200 tons of oil equivalent for the plants with manufacturing capacity of 50000 m3.

Abstract:

Although the Internet of Things (IoT) is an emerging research area which has brought significant advantages for smart homes and smart building applications on the whole, these implementations are still very rare for linguistic landscapes (LLs). Based on a comprehensive literature review, this paper aims to contribute towards narrowing the gap between the employment of the IoT advanced technologies and their proper integration into smart LLs. The analysis focuses on IoT, Big Data, Cloud Computing, LLs, and the challenges and existing solutions, in order to effectively integrate cloud-centric IoT for smart LLs. The paper additionally proposes a framework which involves three main levels comprising different components from IoT, the big data and cloud computing literature that are mostly required for IoT-based smart LLs solutions. Finally, suggestions for the successful integration of IoT into LLs are presented together with future directions for research in this area. The key rational behind this study is to improve the quality of life for people utilizing IoT tools and techniques

Abstract:

This study aimed to determine the relationship of psychosocial learning environment with the Additional Mathematics achievement. The study also aimed to identify psychosocial differences in the learning environments by gender and school type in achievement. Quantitative approaches with a survey design were used for this study. A number of 205 form four Additional Mathematics students from 13 secondary schools in Setiu district were chosen using strata sampling methods as studied subjects. Research instrument were employed which is ‘What is Happening in This Classroom’ (WIHIC). Data were analysed using descriptive and inferential analysis. Descriptive analysis describe the level of perception about psychosocial learning environment while inferential analysis involved the MANOVA and Spearman’s Rho correlation test. The findings showed that the students’ familiarity had the highest level of level of perception. The results also showed that students from Boarding Schools are concerned with the aspects of relationship with each other compared the students in other schools. Spearman’s Rho correlation analysis showed that was significant relationship between psychosocial learning environments with achievement of Additional Mathematics. As a conclusion, psychosocial learning environment is the elements that need to be attention to enhance the achievement of these subjects. The implicates of the study are the psychosocial environment learning is the elements that need to be addressed in order to improve the achievement of this subjects.

Abstract:

Modern apprenticeship training systems require trainees to have the capability to become highly skilled workers. However, most studies only deal with high-skill and knowledgeable terms without deliberating in depth what skills are required in the high-skilled intentions. Thus, this study is conducted to examine the characteristics of the trainers to form the model of modern apprenticeship trainer characteristics to develop highly skilled workers. Modern apprenticeship system should combines elements of mixed trainee ability. Previous study showed that most trainees enter public training institutions due to poor academic results. This creates the view of public vocational training institutions as second-class education. Study using grounded theory method was to identify the factors behinds successful trainees and how they manage their learning process. A total of 32 respondents were interviewed comprising trainees, industry supervisors, and employers. The results showed that there are eight factors that contribute to the success of the trainees in training institutions and also through industrial training before being appointed as an employee. This clearly shows that the success of the apprenticeship training system not only depends on the training system itself but also on the trainees’ characteristics model that are natural or formed by the working environment.

Abstract:

This paper attempts to investigate the impact of CO2 emissions and energy consumption on energy sector in Malaysia using ordinary least square (OLS) method for the period from year 1978 to 2015. The empirical evidence indicates significant positive impact of CO2 emissions on energy consumption for industrial sector and commercial sector. Transport sector has a positive relationship with carbon dioxide emission but insignificant impact on carbon dioxide emission. The coefficient of determination (R-squared) is signal that shows how many percent the independent variables explain the variation on dependent variables. Based on this study, found that that commercial sector and industrial sector is the most sector that give towards the increasing of carbon dioxide emission in Malaysia. the R- squared is 0.990219 @ 99.02% of independend variables of energy consumption explains the movements in carbon dioxide emission, only 0.98% is not explained by independent variables because maybe there is other variables more important than variables that already test.

Abstract:

This paper deals with mixed convection of Casson fluid which flows over a heated surface that has been stretched exponentially. The governing equations that govern the fluid flow are reduced to ordinary differential equations by imposing suitable similarity variables. Numerical computational was carried out to solve for the f “(0) and θ (0) for some arbitrary values of the mixed convection parameter λ, Biot number Bi and Newtonian fluid parameter β when Pr =7.
