Field programmable gate array architecture of proportional-integral-derivative controller
Proportional-integral-derivative (PID) control is widely used in control and automation. PID implementation in software especially using microcontroller requires a lot of CPU execution time. The performance of PID controller can be improved by accelerating control function in hardware. Thus, the performance and throughput can be further improved when incorporated in FPGA architecture system. This project focuses on exploration of hardware architecture of PID controller and targeted for implementation on FPGA system. The architecture exploration include concurrent, serial and pipeline designs, functionality correctness and non-functional verification. These architectures was designed to support modularity and can be use for other control applications. Serial design architecture of PID is able to reduce - 60% of datapath unit resources compared to concurrent design but it required five cycles to produce the output. High throughput can be achieve using pipeline design and required 7 more registers compared to concurrent design with pipeline speed up about 1.5 and five times compared to serial design architecture
Identification of rainfall temporal patterns
Temporal pattern for rainfall events is required in the design and evaluation of hydrologic safety for hydraulic structures. In this paper, a method of statistical cluster analysis is applied to identify event-based representative temporal rainfall pattern in fourteen stations in Johor. The 8 hour separation time of no rain is used to divide the 5 years rainfall data into individual rainfall event according to the monsoons. The analysis is implemented from the dimensionless mass curve ordinates as the attributes in statistical cluster analysis of the cumulative storm depth over the non-dimensionalized time. As a result, three representative rainstorm patterns are identified and classified under the two basic types of advanced-type (A) and central-peak type (C) for northeast and southwest monsoon. Meanwhile, only one basic type is identified to represent rainstorm pattern during the inter-monsoon that is advanced type (A). In addition, the rainfall pattern is dependent on rainfall depth and duration, season and geographical location by contingency table test. The rainfall information presently used for design in Malaysia is very dissimilar to the representative curves derived in this study. The identification of three representative rainfall temporal patterns according to the monsoon seasons in Johor can be used as a basis to stochastically generate the plausible rainfall hyetographs of the specified pattern in Johor

Development of generalized feed forward network for predicting annual flood (depth) of a tropical river
The modeling of rainfall-runoff relationship in a watershed is very important in designing hydraulic structures, controlling flood and managing storm water. Artificial Neural Networks (ANNs) are known as having the ability to model nonlinear mechanisms. This study aimed at developing a Generalized Feed Forward (GFF) network model for predicting annual flood (depth) of Johor River in Peninsular Malaysia. In order to avoid over training, cross-validation technique was performed for optimizing the model. In addition, predictive uncertainty index was used to protect of over parameterization. The governing training algorithm was back propagation with momentum term and tangent hyperbolic types was used as transfer function for hidden and output layers. The results showed that the optimum architecture was derived by linear tangent hyperbolic transfer function for both hidden and output layers. The values of Nash and Sutcliffe (NS) and Root mean square error (RMSE) obtained 0.98 and 5.92 for the test period. Cross validation evaluation showed 9 process elements is adequate in hidden layer for optimum generalization by considering the predictive uncertainty index obtained (0.14) for test period which is acceptable
Introducing Shariah compliant hotels as a new tourism product: the case of Malaysia
This paper is concerned with the concept of Shariah compliant hotels which are introduced to attract a
growing Muslim travelers market. Major attributes of Shariah compliant hotels are investigated based on
the available literature and secondary data. The concept of Shariah compliant hotels should be clearly
defined and it is suggested that the relevant stakeholders to play important roles in contributing to the
understanding of such concept. The idea of setting up of Shariah compliant hotel is very interesting
indeed considering the growing population of Muslim travelers. In the case of Malaysia, the concept of
Shariah compliant hotel is yet to be explored and warranted further investigation. It is recommended that
the setting up of Shariah compliant hotels to be promoted aggressively to stimulate the tourism industry
which may be cater to the growing Islamic market especially from the Middle East region
Effect analysis on strategy implementation drivers
Currently, the strategy implementation is believed to be a dynamic activity within strategic management process. The main objective of this research is to examine the structural relationships between strategy implementation and performance within the small and medium manufacturing firms. In order to implement strategy effectively, it is crucial to consider several organizational issues. The literature indicates that, several researchers have identified three fundamental factors in Strategy Implementation: the structure, leadership style and resources. The current research particularly discusses the main drivers of strategy implementation, prevailing in the smaller industries. In this regard, empirical relationships are established relating strategy implementation and performance of the firm. We provide a structural equation model on the relationship among drivers of strategy implementation and organization performance and also sensitivity analysis on the drivers

Hiving Method Of Stingless Bee Domestication For Sustainable Meliponiculture
The stingless bee rearing is emergent agriculture activity in Malaysia. The stingless bee products
including honey and bee bread, which are stored in propolis-rich pots. The activities of stingless bee
rearing are referred to as meliponiculture and it is a crucial activity that encourages the conservation of
stingless bees and helping to reduce deforestation due to feral stingless bee colony hunting. Here, we
studied direct and indirect hiving method of the feral stingless bee colony into a newly innovative hive
called Mustafa-Hive. In the hive, the brood was placed into a split-able throne as a brood chamber and
inserted into an air-jacketed palace as an insulation chamber. The honey cassette was used on the hive
to induce a monolayer honey pot formation. Findings have shown that all broods in an indirect hiving
module provide cleaner broods from the sawdust compared to the direct hiving process. Indiriect hiving
gave 100% colony viability and supported by noteworthy yield pot formations in the honeycassette.
Findings also showed an average of 4.5ml honey were extracted from each pot to produce an average
of 99ml and 256.5ml honey at week 2 and week 4 for every hive, respectively. As conclusion, the
indirect hiving method and the use of Mustafa-hive ensures colony survival and induced formation of
monolayer honey pots. Thus this hiving module encourage for sustainable meliponiculture, enables for
absolute and hygienic honey extractions from honey cassette which could indirectly promote the
development of the stingless bee industr
