Effects of Aerodynamics Changes on A Car Caused by Another in Its Proximity: An Experimental Study
The study of road vehicle aerodynamics is quite different from that of an aircraft
aerodynamics which mainly focuses on producing lift. The subject does not lend
itself to traditional methods such as mathematical analysis where there are no
straightforward methods for predicting how air will flow around a given vehicle
shape and no equivalent of the simple formulae used in earlier days for determining
the lift and drag of an aircraft from its geometry. With regards to this Final Year
Project (FYP), Experiments is to be conducted to study the effect of aerodynamics
change on a car caused by another in its proximity. For this experimentation project,
the Kelisa car’s is to be considered as the model which enable in achieving
dimensional similarity and more accurate in getting the experimental result. In the
experiments, certain ranges of distance between the two cars were to be highlighted
in order to show the drag force and other aerodynamic changes that might occur. The
aerodynamic changes are to be studied on two model vehicles using a wind tunnel
equipped with the necessary measuring equipment. The study is focused on the
effects of the wake of a vehicle to another vehicle in tailing position (back-to-back),
where the experiment is done using wind tunnel and scaled vehicle models. The
model is to be manufactured by using CNC machining process
2-D strength prediction of single-row multi-bolted joints woven fabric kenaf composites
Implementation of multi-bolts arrangements in structures connections are commonplace in steel design to allow for joint efficiency and stronger connections. Woven fabric kenaf fibers are potentially used as reinforcement in composite materials due to excellent specific strength, renewability and less hazardous during handling as compared to commercial fibers. A two-dimensional Extended Finite Element Method (XFEM) framework of single-row multi-bolted joints has been developed to study the stress distribution and predict the joint bearing stress at failure. Stress distribution among adjacent bolts were compared along the hole boundary and net-tension plane, suggesting net-tension failure occurred at end-bolt. The predicted bearing strength from finite element modelling are validated against experimental framework. The testing series under investigated consists of four datasets from single-row 2 bolts and 3 bolts single-lap joints. Current study showed that the XFEM models demonstrated good agreements with the experimental results
Assessments of healthy lifestyle practices using fuzzy / Mohd Khairi Mohd Adnan
The changes in the health behaviour of most individual nowadays are showing a trend towards a less healthy lifestyle. There are low levels of awareness about their health states. Health experts now describe lifestyle as one of the most important factors affecting health. In fact, it is estimated that as many as seven of the ten leading causes of death could be reduced through common-sense changes in lifestyle. Lifestyle assessment or evaluate is the process of identifying behavioural risk factors particular to an individual with the intent to encourage behaviour change for the prevention of poor health outcomes in the future. Improving the health of people living requires an initial assessment of their health status. Various instruments exist to measure perceived health. One such instrument is simply a question that asks people to rate their health as poor, fair, good, very good, or excellent. Six categories of lifestyle behaviour has used in this research, there are cigarette smoking, alcohol and drugs, eating habits, exercise/fitness, stress control and last one is safety. As fuzzy method has high potential of reasoning capability, the purpose of this research study is to investigate and develop an assessment system using fuzzy which are able to rate the health lifestyle practices based on behaviour of those six categories by answering a few provided questionnaire related to health style
ONLINE 2D SOCCER GAME USING SOCKS PROGRAMMING & AGENTS
A soccer game is designed to simulate a real soccer game that is played all over the
world. The more realistic the game is, the more it will be played by people. The
development of soccer games nowadays are moving towards creating 3D graphics that
are almost human-like and artificial intelligence that are nearly perfect as a real soccer
players. Some of them allow multiplayer gameplay which allows two people at different
places connect to each other or to a game server and play the same game as opponent or
teammates. This entire feature requires a personal computer which has fast processing
power, a lot of memories, and a high-speed graphic processing chip. The objective of this
project is to design a 2D soccer game which has the AI capability and multiplayer
gameplay but only need minimum requirement to play it. To design such game, a lot of
study and research had to be done in the field of artificial intelligence and networking.
The scope of study also involves the research on the physics of the ball, such as the
movement and interaction with other players. This system is developed using Visual
'
Studio 2005 with the installment of Microsoft .NET 2.0 framework. Coding is done using
WinSocks programming for the multiplayer mode, GDI+ Programming (.NET APis) for
graphical details and Visual Basic language for AI and other features. All features in the
game have meet the targeted requirements. There are still rooms for improvements
mostly on the AI

Kefahaman dan pengalaman akhlak dalam kalangan pelajar Politeknik Sultan Abdul Halim Mu'adzan Shah
Akhlak yang baik adalah hasil daripada kefahaman ilmu pengetahuan yang diperolehi secara formal dan tidak formal.Dewasa ini, kepincangan akhlak timbul dalam masyakat yang sukar dibendung lagi. Kurangnya penghayatan akhlak Islam di pengaruhi oleh pelbagai faktor antaranya faktor kefahaman pelajar serta sikap pelajar.Kajian ini bertujuan untuk mengenalpasti tahap kefahaman dan pengamalan akhlak dalam kalangan pelajar, untuk menentukan perbezaan kefahaman dan pengamalan akhlak berdasarkan demografi jantina dan tempat tinggal. Seramai 381 pelajar Politeknik Sultan Abdul Halim Mu’adzam Shah dipilih sebagai responden untuk menjawab soal selidik.Data yang diperolehi daripada borang kaji selidik dianalisis menggunakan perisian program Statistical Packages For Social Science (SPSS) versi 20.0 dan dapatan kajian dihuraikan dengan menggunakan kaedah statistik deskriptif dan inferensi untuk menganalisa hipotesis kajian.Analisa data melibatkan min dan ujian-t.Kebolehpercayaan Alpha Cronbach bagi item borang kaji selidik soalan kefahaman akhlak iaitu 0.94 dan soalan pengamalan akhlak iaitu 0.97 adalah tinggi.Dapatan kajian mendapati tahap kefahaman ajaran Islam meliputi akhlak dalam kalangan responden berada pada tahap yang tertinggi bagi setiap aspek yang dikaji. Manakala dapatan kajian mendapati tahap pengamalan ajaran Islam meliputi akhlak juga tinggi.Namun terdapat sebahagian kecil responden tidak mengamalkan apa yang mereka faham terutama perkara-perkara yang berkaitan akhlak. Oleh itu, implikasi kajian ini menunjukkan bahawa penekanan aspek pengamalan ajaran Islam sangat penting agar pelajar menjadi seorang muslim yang mengamalkan akhlak yang baik dalam kehidupan harian berlandaskan al-Quran dan as-Sunnah
Toxic Effects Of Signal Grass (Brachiaria Decumbens) On Drug- Metabolizing Enzyme Activities In Sheep
Signal grass (Brachiaria decumbens) is widely grown on livestock farms in
many countries including Malaysia due to its high productivity and nutritive value.
Unfortunately, it is toxic to sheep and goats causing a severe hepatic and renal
damage, and death. Two experiments were conducted to determine the effect of the
toxicity of signal grass (B. decumbens) on the activity of drug-metabolizing enzymes
(DME) in sheep and cattle. It was hypothesized that the activities of selected
enzymes would be affected during intoxication and that differences in the activity
level of the enzymes in the two species might explain why cattle were safe from the
toxic effect of the grass. Twenty-three healthy Wiltshire-Malin crossed rams, aged 1 4-
1 6 months were used, fifteen for the first experiment and eight for the later. In the
first experiment, aniline 4-hydroxylase (A4H), aminopyrine N-demethylase (AND),
UDP-glucuronyl transferase (UDPGT), glutathione S-transferase (GST) and
cytochrome P450 of the liver and kidney of the control and intoxicated sheep wer
Improvements in separation of peptides using capillary electrophoresis
In this review, various aspect concerning the resolution of capillary electrophoresis for
nine standard peptides ( namely, bradykinin, bradykinin fragment 1-5, substance P,
Arg-vasopressin, luteinizing hormone·releasing hormone (LHRH), bombesin, leucine-enkephalin,
methionine-enkephalin and oxytocin). The experiment were carried out
using 100 mM phosphate buffer as the separation buffer, added with acetonitrile
(ACN) and triethylamine (TEA) as an additive at low pH. The resolution of these
peptides was examined at different concentrations of ACN ( 0, 10, 20, 30, 40, 50 and
60 %) and TEA ( 0, 5, 10, 20, 30, 40 ppm) at their respective final pH. The results
showed that the resolution was improve when 10 % of ACN added in the BGE. The
optimum resolution found at 40 % ACN where all peptides were resolved at baseline.
The shape was perfectly symmetrical. As for the TEA addition, adding 5 ppm already
improve the peaks and addition of 30 ppm TEA gives the optimum resolution
compare to all. For both ACN and TEA, adding more concentrated additive gives poor
resolution of peptides. The investigation was continued by applying voltage ( 23, 24,
25,26 and 27 kV). Shorter time separation achieved when voltage increased. The best
resolution found at 25 kV. However, more voltage caused poor resolution
