Bio-inspired novel hybrid vertical axis wind turbine / Ts. Dr. Ashwindran Naidu Sanderasagran and Dr. Azizuddin Abd Aziz
No full textToday several countries are investing their resources on the development of renewable energy, the focused sector of development in renewable energy is wind power generation. Energy harvested by the wind turbine are relative to wind speed potential regardless the type or configuration of wind turbine used. Design modification were done on wind turbine by engineers in order to adapt the wind speed of the desired geographical area. In Malaysia studies indicated that the average wind speed potential is 2.1 m/s dependent on season and geographical area, which is not adequate in harvesting energy in megawatt scale. Researches indicates that, drag driven wind turbines VAWTs are suitable in harvesting wind energy in low wind speed potential. The objective of this research is to present the aerodynamics performance of a novel bio-inspired hybrid drag driven wind turbine and with two sub objective; operational under low speed wind potential, and low manufacturing cost. In this research, the novel hybrid design were created by the hybridizations of three design elements inspired by nature; Albatross bird’s wing, Pitcher plant, and Tulip flower. The novel wind turbine were design based on the principals of VAWT’s design parameters, in order to maintain design’s practicality and performance. Ansys fluent were used to perform aerodynamic performance study on the design. The usefulness of this research is to broaden the knowledge and understanding of bio-mimicry design implementation and adaptation into wind energy harvesting machinery

No full textIn the title compound, [Fe(C13H11O2)2], there are markedly different orientations of the two phenylmethoxycarbonyl substituents [O—C—C—C torsion angles = 84.5 (3) and 139.6 (2)°]. These orientations are mediated by a number of intermolecular C—H...O interactions, which result in a one-dimensional hydrogen-bonded network of molecules
Direct accounting system: improving data capture system for timely annual public accounts / Wan Azmin Wan Abd. Aziz
No full textEversince i am aware of the need of proper public accounting system for public monies, I wished I had an indepth knowledge and a reference material from which I could very quickly obtain accurate and concise information regarding the tedious preparation of Annual Public Accounts of the Malaysian Government. I have no doubt that many Malaysians have experienced this need. It is obvious that the Annual Account itself communicates no messages especially to those who have not had the advantage of learning this highly specialised field previously and practical working experience. It is my hope that this research! paper will make my dream comes true and also assist those readers who were curious enough to know the system adopted by the Government in improving data capture for preparation of Annual Public Accounts. I must concede and stress that this is, in essence, only a project paper and to those who demand a detailed exposition of the finer points of the system, may I humbly suggest that they refer to more advanced works by more eminent and di st i ngui shed author s/r esear c hers. However, I am confident that the areas covered ar& comprehensive enough to aid fellow students in their studies in this particular topic

Comparison of Cooling Cost Effectiveness Between Unitary and Central Cooling System
No full textAir conditioning is a basic need in building spaces to provide indoor comfort. This
research describes the evaluation of cooling cost effectiveness between unitary and
central chiller cooling system. Operational cost involving initial, energy and
maintenance for both systems was analysed throughout the life span period. A case
study was carried out where cooling load requirement of all conditioned spaces was
determined using cooling load temperature difference 1 cooling load factor method.
Currently in-use unitary system data was gathered and an all-water type central
cooling system was proposed as an alternative. Main equipment capacity of the
central system was designed based on cooling load and appropriate heat equation.
The study shows that the central system is the better option for high air conditioning
application of more than 60 kW heat gain. Although central system first cost is
almost double than that of unitary system, it has the advantage of much higher life
span. Cumulative cost analysis for the case study indicates that the investment of
central system provides a payback period of eight years. In addition, the central
system also contributes towards energy conservation by offering lower total power
input of its equipment
Air-conditioning system with simultaneous control of sensible and latent heat for building energy conservation in Malaysia
No full textBuildings in tropical countries such as Malaysia are exposed to excessive amount of solar heat during daytime occupancy. In addition to that, the outdoor air contains excessive humidity due to the nature of the climate.
Air-conditioning system is the main energy consumer of the buildings, more so with the requirement of the full 12 months cooling period in the country. The increasing demand of energy due to its status as a developing country puts Malaysia in a critical situation in terms of building sustainability. Another quandary associated with tropical environment is the indoor thermal comfort due
to the high humidity. The usage of normal air-conditioning system means that the room has to be overcooled in order to bring down the humidity. Unfortunately, the low temperature set-point technique is neither comfort cautious nor energy friendly. There is an option to solve the humidity problems by the use of the
outdoor air treatment system which neutralizes the incoming fresh air into the room. However, high equipment cost renders the system unfavorable in Malaysia.
Therefore, the viable solution to the high latent load requires an innovative system that is affordable, runs at relatively low energy consumption yet be able to provide satisfactory indoor thermal comfort. In the research, a new air-conditioning approach termed Dual ABU (air handling unit) system is proposed to be the answer. The simplicity in arrangement and control setup ensures that the system can be reasonably priced. On top of that, it can be designed as an add-on configuration to the existing air-conditioning. The function of Latent AHU in the proposed system is to remove moisture from the conditioned room up to the desired humidity level and in the process the room temperature is also fractionally reduced. The Sensible AHU completes the task by removing the remaining sensible heat so that the room temperature is maintained at the required set-point. By reducing the relative humidity to 50%, a much lower value than
that of the normal air-conditioning could offer, room temperature of the new system is shifted higher to 26°C in order to reduce the energy consumption. However, thermal comfort of the occupants has not been compromised. The performance of the proposed system is evaluated through simulation approach. The result shows that the new system could offer energy savings of between 10.2 to 13.6% in constant-air-volume configuration and between 10.7 to 13.2% in variable-air-volume configuration compared to normal air-conditioning system. The procedure to design of the proposed system using manual calculation and psychrometric chart is also being clarified. In addition, the possibility to retrofit the new system into existing air-conditioning system is explained at the end of the research
Sejauh mana peranan agama dalam politik Malaysia
No full textRamai sarjana dan ahli politik Malaysia berpandangan Tsunami Politik pada 8 Mac 2008 didakwa sebagai titik mula bagi perubahan dalam landskap politik Malaysia. Agama yang sekian lama menjadi elemen terpenting dalam politik Malaysia yang perkauman dilihat semakin kurang peranannya. Politik Malaysia pasca Tsunami Politik dilihat lebih ‘sekular’, ‘buta warna’ atau tidak komunal. Bersandarkan keputusan pilihan raya umum 8 Mac 2008 dan pelbagai pilihanraya kecil yang kebanyakannya lebih memihak kepada Pakatan Rakyat, agama dilihat semakin hilang peranan dalam politik Malaysia. Begitu juga dengan penggunaan agama dalam memasarkan politik, parti-parti yang dahulunya begitu cenderung dalam menggunakan agama bagi beroleh sokongan nampaknya memilih pendekatan lembut berbanding radikal.
Justeru itu, kajian ini cuba melihat sejauh mana agama memainkan peranan dalam politik Malaysia secara menyeluruh
Adapting authoritarianism: institutions and co-optation in Egypt and Syria
No full textThis PhD thesis compares Egypt and Syria’s authoritarian political systems. While the tendency in social science political research treats Egypt and Syria as similarly authoritarian, this research emphasizes differences between the two systems with special reference to institutions and co-optation. Rather than reducibly understanding Egypt and Syria as sharing similar histories, institutional arrangements, or ascribing to the oft-repeated convention that “Syria is Egypt but 10 years behind,” this thesis focuses on how events and individual histories shaped each states current institutional strengthens and weaknesses. Specifically, it explains the how varying institutional politicization or de-politicization affects each state’s capabilities for co-opting elite and non-elite individuals.
Beginning with a theoretical framework that considers the limited utility of democratization and transition theoretical approaches, the work underscores the persistence and durability of authoritarianism. Chapter two details the politicized institutional divergence between Egypt and Syria that began in the 1970s. Chapter three and four examines how institutional politicization or de-politicization affects elite and non-elite individual co-optation in Egypt and Syria. Chapter five discusses the study’s general conclusions and theoretical implications.
This thesis’s argument is that Egypt and Syria co-opt elites and non-elites differently because of the varying degrees of institutional politicization in each governance system. Rather than view one country as more politically developed than the other, this work argues that Syria’s political institutions are more politicized than their Egyptian counterparts. Syria’s political arena is, thus, described as politicized-patrimonialism. Syria’s politicized-patrimonial arena produces uneven co-optation of elites and non-elites as they are diffused through competing institutions. Conversely, the Egyptian political arena remains highly personalized as weak institutions and individuals are manipulated and molded according to the president’s ruling clique. This is referred to as personalized-patrimonialism. As a consequence, Egypt’s political establishment demonstrates more flexibility in ad hoc altering and adapting its arena depending on the emergence of crises.
This study’s theoretical implications suggest that, contrary to modernization and democratization theory’s adage that institutions lead to a political development, politicized institutions within a patrimonial order actually hinder regime adaptation because consensus is harder to achieve and maintain. It is within this context that Egypt’s de-politicized institutional framework advantages its top political elite. In this reading of Egyptian and Syrian politics, Egypt’s personalized political arena is more adaptable than Syria’s. These conclusions do not indicate that political reform is a process underway in either state
