Freight transport by road: challenges towards the freight transport efficiency / Mimi Suriani Mat Daud
No full textFreight transport by road is the transportation of the raw material and finishing product from one location to another location and it is essential for the development of the country as it support the daily life of the residents and operation of industry. However, the challenges in freight transport by road has becomes the limitation to its efficiency. Therefore, identification of the challenges in freight transport by road is a need. The aim of this research is to identify the factors behind the challenges in freight transport by road. To achieve the aim, three objectives have been formulated which are identification of the challenges in freight transport by road, evaluation of the characteristic of freight transport by road and examination of the factors behind the challenges in freight transport by road. To achieve all the objectives, questionnaire survey, observation method and the development of partial least square (PLS) have been conducted. Questionnaire survey is conducted to the haulage companies. 12 challenges regarding the freight transport by road have being survey and the results indicates that the major challenges in freight transport by road are poor road condition access to port, congestion and poor loading/unloading activity at ports. From the results of observations on five selected major roads from Port Klang to Kuala Lumpur meanwhile, verified that some of challenges as stated by haulage companies in the questionnaire survey especially in terms of road condition and congestion, are still exist at present situations. The model for the challenges factor in freight transport by road then developed by using PLS. Six hypotheses are establishing and three were accepted. These three accepted hypothesis are Management has a positive significance influence to the Distribution, Authority has a positive significance influence to the Others and Authority has a positive significance influence to the Management, and reveal the challenges factor in freight transport by road. Therefore, it is hope that the government can address these factors in increasing the efficiency in freight transport by road
The study of stemming algorithm on Malay words that begin with alphabets P, Q, Y, and Z from the translated Al-Quran / Suriani Mat
No full textThis thesis concerns a Malay language documents retrieval system. Stemming algorithm, Malay Quran translated documents and root dictionaries are used in order to complete this study. The performance of a Malay stemming algorithm is tested based on words beginning with letter 'p', 'q', 'y' and 'z', using 5 experiments. First experiment uses the original set of data collections. In second experiment, new words are added in the dictionary and the total value for i ' , 'm', 'p', 'q', 'y' and 'z' are modified in the header file "dcvarnew.h". Other than that, affixes rule format in file "rule.txt" are added and misspell words are corrected. Third, the locations of rules in file "rule.txt" are changed. For fourth experiment, words that have more than one root, old spelling words and spoken word are deleted from the dictionary. After the modification, the total value for 'k', 'm\ 'n' and 'p' in header file "dcvarnew.h" are corrected again. Otherwise, new code is added into module 'ubahejaan'. In fifth experiment, the spoken word is deleted from the dictionary and the total value for 'p' in file "dcvarnew.h" is corrected. Then alternative rule to solve the words pengawal, pengawalan and perangan is carried out. The objective of this project is achieved when the best order of the rules to use to stem the words that beginning with p', 'q', 'y' and 'z' is met. This involves the use of two combinations simultaneously such as the pair combination of 1234 as primary combinations and 3124 as the secondary. First, all the words used the 1234 combination, and if the program encountered that the words cannot be solved correctly, combination will be shifted to the secondary combination that is 3124 combination. These experiments can serves as a benchmark for future research in Malay language

Determination of defects and damage modes in kenaf-reinforced epoxy composites under fatigue loading using thermal imaging and SEM techniques
No full textIn engineering design, concerns arose on the fatigue behaviours of composite materials.Much effort has been done to estimate the fatigue life by which destructive techniques were commonly used. Recently, non-destructive techniques (NDT) are increasingly being used on composite materials to detect defects. Parallel to the development, shifting interests from traditional monolithic materials to fiber reinforced polymer based materials have been demonstrated by researchers and engineers. Nevertheless,
information on the use of NDT on natural fiber reinforced composite materials is still sparse.
The present study was set out to detect defects and estimate fatigue life in natural fiber reinforced composite materials. In making the composite, kenaf bast was used as a reinforcement fiber with epoxy as the matrix. The NDT employed to serve the study purposes are Infrared (IR) thermal imaging and optical microscope. In parallel,destructive technique (DT) was also used in this study specifically in carrying out the fatigue tension-tension test and scanning electron microscope (SEM). By and large, the DT was used just to verify all the results by NDT.
The advantages of using NDT via IR thermal imaging in kenaf reinforced epoxy composites to estimate the fatigue life are evidenced in the following results: IR has
successfully detected five types of manufacturing defects in kenaf reinforced epoxy composites due to manufacturing process. The defects are voids, resin rich area, pockets
of undispersed cross-linker, misaligned fiber and regions where resin has poorly wetted the fibers. Subsequently, IR thermal imaging has significantly determined fatigue
damage in kenaf reinforced epoxy composites. In addition, fatigue damage modes has also been predicted and determined by the types of defects occurs due to manufacturing process. This proves that IR has successfully been a significant NDT in estimating
fatigue life due to fatigue damage, proved experimentally and interpreted by the S-N curve. In terms of fatigue resistance, it is found that 60% fiber volume fraction kenaf reinforced epoxy composites specimen has the highest resistance at 119.71-53.20 MPa. Finally, based on damage accumulation, a model of fatigue life estimation, namely S-IR has been proposed
Review of development and characterization of sugar palm fiber reinforced polymer composites
No full textSugar palm fiber (SPF) has been gaining interest in the area of natural fiber composites owing to its good mechanical properties, high durability, good resistance to seawater and biodegradability. SPF is among the natural fibers that could be a potential material to be used as reinforcement in polymer composites. Incorporation of SPF as reinforcement in polymer composites has resulted in improvement in the physical, mechanical, and thermal properties of the composites. Another interesting point is the low density of SPF, which helps to reduce the weight of the composites, as well as increase the biodegradability. Much research has been carried out to determine the suitability of SPF as reinforcement in polymer composites. SPF-reinforced composites are suitable for a wide range of applications such as automotive anti-roll bars, rescue boats and drain covers. Chapter 2 provides an overview of the characteristics and development of various products derived from SPF-reinforced composites and the future direction of SPF and SPF-reinforced composites
