Abstract: Al-Murabahah is an Islamic financing facility used in
asset financing, the profit rate of the contract is determined by
components which are also being used in the conventional banking.
Such are cost of fund, overhead cost, risk premium cost and bank-s
profit margin. At the same time, the profit rate determined by Islamic
banking system also refers to Inter-Bank Offered Rate (LIBOR) in
London as a benchmark. This practice has risen arguments among
Muslim scholars in term of its validity of the contract; whether the
contract maintains the Shariah compliance or not. This paper aims to
explore the view of Shariah towards the above components practiced
by Islamic Banking in determining the profit rate of al-murabahah
asset financing in Malaysia. This is a comparative research which
applied the views of Muslim scholars from all major mazahibs in
Islamic jurisprudence and examined the practices by Islamic banks in
Malaysia for the above components. The study found that the shariah
accepts all the components with conditions. The cost of fund is
accepted as a portion of al-mudarabah-s profit, the overhead cost is
accepted as a cost of product, risk premium cost consist of business
risk and mitigation risk are accepted through the concept of alta-awun
and bank-s profit margin is accepted as a right of bank after
venturing in risky investment.
Abstract: The objective of this contribution is to study the
performances in terms of bit error rate, of space-time code algorithms
applied to MIMO communication in tunnels. Indeed, the channel
characteristics in a tunnel are quite different than those of urban or
indoor environment, due to the guiding effect of the tunnel.
Therefore, MIMO channel matrices have been measured in a straight
tunnel, in a frequency band around 3GHz. Correlation between array
elements and properties of the MIMO matrices are first studied as a
function of the distance between the transmitter and the receiver.
Then, owing to a software tool simulating the link, predicted values
of bit error rate are given for VLAST, OSTBC and QSTBC
algorithms applied to a MIMO configuration with 2 or 4 array
elements. Results are interpreted from the analysis of the channel
properties.
Abstract: This study experimentally investigates the heat transfer effects of forced convection and natural convection under different substrate openings design. A computational fluid dynamics (CFD) model was established and implemented to verify and explain the experimental results and heat transfer behavior. It is found that different opening position will destroy the growth of the boundary layer on substrates to alter the cooling ability for both forced under low Reynolds number and natural convection. Nevertheless, having too many opening may reduce heat conduction and affect the overall heat transfer performance. This study provides future researchers with a guideline on designing and electronic package manufacturing.
Abstract: This research is to explore the satisfaction for senior
citizens on continuing education in Taiwan. The purpose of this
research aims at the difference on teacher-s teaching, personal
relationship, learning result, materials and environment. Through
different sexual and living area as the background variables, a
questionnaire is adopted as the methodology in this research. Three
results are found in this research. In overall, senior citizens taking
continuing education put the most important attention on personal
relationship but materials and leaning environment put the least. There
is a significant difference on personal relationship, teacher-s teaching
and research result between different sexes. Female senior citizens
attach more importance to teacher-s teaching and learning results but
male senior citizens value on personal relationship. Another
significant difference is shown on teacher-s teaching and personal
relationship because of senior citizens living area. Urban senior
citizens put importance on personal relationship and rural senior
citizens respect teacher-s teaching more.
Abstract: In recent years, though, the concept of fit has been
now in widespread used in strategic management research, it is in its
infancy for applying fit concept to service innovation issue. Therefore,
drawing on the concept of fit, this present research proposed an
innovation service fit model within service innovation, market
orientation, marketing strategy, and IT adoption are coexisted. The
perspective of fit as covariation will be employed to test the hypothesis
and identify the effects of fit. We contend that the fit among these four
factors will contribution to business performance. Finally, according
to the empirical data collected from manufacturing, service, and
financial industry in Taiwan, meaningful findings and conclusions
will be proposed and discussed.
Abstract: In this paper, the difference between the Alternating
Direction Method (ADM) and the Non-Splitting Method (NSM) is
investigated, while both methods applied to the simulations for 2-D
multimaterial radiation diffusion issues. Although the ADM have the
same accuracy orders with the NSM on the uniform meshes, the
accuracy of ADM will decrease on the distorted meshes or the
boundary of domain. Numerical experiments are carried out to
confirm the theoretical predication.
Abstract: The increasing divorce and fertility rates outside of marriage, the changing values in the last decades have led to a high prevalence of single parent families. Currently, worldwide, singleparent families represent about a quarter of all families. Recent changes occurring in the structure of single-parent families and also the multitude of factors that influence the quality of life of these families require the development of new research tools in order to provide foundations for social policies addressed to this type of family. The purpose of this paper is to present an analysis concerning the quality of life for single parent families in Romania, based on data collected through a research methodology developed by the authors within a scientific research project funded by a national grant called Partnerships in priority areas.
Abstract: 15 strains of oil-destructing microorganisms were
isolated from oil polluted soil of Western Kazakhstan. Strains 2-A
and 41-3 with the highest oil-destructing activities were chosen from
them. It was shown that these strains oxidized n-alkanes very well,
but isoalkanes, isoparaffin, cycloparaffin and heavy aromatic
compounds were destructed very slowly. These both strains were
tested as preparations for bioremediation of oil-polluted soil in model
and field experiments. The degree of utilizing of soil oil by this
preparation was 79-84 % in field experiments.
Abstract: It-s difficult for China-s current land transfer
institutions limited to county-wide to solve the contradiction between
urban-rural development and construction land shortage. On the basis of analyzing China-s construction land transfer system, and evaluation
toward Transfer of development rights (TDR) practices in Anhui and
Chongqing, the passage proposes: (1) we should establish a multi-level
land indicators trade market under the guidance of regional spatial
objectives, and allow land transfer paid across cities and counties
within a specific area following the regulation of both government and
market; (2) it would be better to combine organically the policy ntentions of land plan, regional plan, urban plan and economic plan, and link them with land indicators transfer to promote a wider range of
urban-rural balance and regional coordination.
Abstract: This paper explores oil prices changes impact on energy policy of Kazakhstan in 2001-2009. It involves the role of oil income to the economic development, process of diversification of internal and external energy policy of Kazakhstan, and the changes in oil law towards subsoil users.
Abstract: In recent years, an increased competition and lower profit margins have necessitated a focus on improving the performance of the product development process, an area that traditionally have been excluded from detailed steering and evaluation. A systematic improvement requires a good understanding of the current performance, wherefore the interest for product development performance measurement has increased dramatically. This paper presents a case study that evaluates the performance of the product development performance measurement system used in a Swedish company that is a part of a global corporate group. The study is based on internal documentation and eighteen in-depth interviews with stakeholders involved in the product development process. The results from the case study includes a description of what metrics that are in use, how these are employed, and its affect on the quality of the performance measurement system. Especially, the importance of having a well-defined process proved to have a major impact on the quality of the performance measurement system in this particular case.
Abstract: In this work, axisymetric CFD simulation of fixed bed
GTL reactor has been conducted, using computational fluid dynamics
(CFD). In fixed bed CFD modeling, when N (tube-to-particle
diameter ratio) has a large value, it is common to consider the packed
bed as a porous media. Synthesis gas (a mixture of predominantly
carbon monoxide and hydrogen) was fed to the reactor. The reactor
length was 20 cm, divided to three sections. The porous zone was in
the middle section of the reactor. The model equations were solved
employing finite volume method. The effects of particle diameter,
bed voidage, fluid velocity and bed length on pressure drop have
been investigated. Simulation results showed these parameters could
have remarkable impacts on the reactor pressure drop.
Abstract: This paper presents an architecture to assist in the

implementations of tools based on this architecture are also described
in this paper. These tools are applied to the real world problem of
fault attack emulation and detection in cryptographic algorithms.
Abstract: The main aims in this research are to study the solid
waste generation in the Faculty of Engineering and Built
Environment in the UKM and at the same time to determine
composition and some of the waste characteristics likewise: moisture
content, density, pH and C/N ratio. For this purpose multiple
campaigns were conducted to collect the wastes produced in all
hostels, faculties, offices and so on, during 24th of February till 2nd
of March 2009, measure and investigate them with regard to both
physical and chemical characteristics leading to highlight the
necessary management policies. Research locations are Faculty of
Engineering and the Canteen nearby that. From the result gained, the
most suitable solid waste management solution will be proposed to
UKM. The average solid waste generation rate in UKM is 203.38
kg/day. The composition of solid waste generated are glass, plastic,
metal, aluminum, organic and inorganic waste and others waste.
From the laboratory result, the average moisture content, density, pH
and C/N ratio values from the solid waste generated are 49.74%,
165.1 kg/m3, 5.3, and 7:1 respectively. Since, the food waste (organic
waste) were the most dominant component, around 62% from the
total waste generated hence, the most suitable solid waste
management solution is composting.
Abstract: Innovations, especially technological, are considered
key-drivers for sustainable economic growth and competitiveness in
the globalised world. As such they should also play an important role
in the process of economical convergence inside the EU.
Unfortunately, the problem of insufficient innovation performance
concerns around half of the EU countries. Poland shows that a lack of
a consistent high-tech financing system constitutes a serious obstacle
for the development of innovative firms. In this article we will
evaluate these questions referring to the example of Ammono S.A., a
Polish company established to develop and commercialise an original
technology for the production of bulk GaN crystals. We will focus on
its efforts to accumulate the financial resources necessary at different
stages of its development. The purpose of this article is to suggest
possible ways to improve the national innovative system, which
would make it more competent in generating high-tech leaders.
Abstract: The gel-supported precipitation (GSP) process can be
used to make spherical particles (spherules) of nuclear fuel,
particularly for very high temperature reactors (VHTR) and even for
implementing the process called SPHEREPAC. In these different
cases, the main characteristics are the sphericity of the particles to be
manufactured and the control over their grain size. Nonetheless,
depending on the specifications defined for these spherical particles,
the GSP process has intrinsic limits, particularly when fabricating
very small particles. This paper describes the use of secondary
fragmentation (water, water/PVA and uranyl nitrate) on solid
surfaces under varying temperature and vibration conditions to assess
the relevance of using this new technique to manufacture very small
spherical particles by means of a modified GSP process. The
fragmentation mechanisms are monitored and analysed, before the
trends for its subsequent optimised application are described.
Abstract: Representation and description of object shapes by the
slopes of their contours or borders are proposed. The idea is to capture
the essence of the features that make it easier for a shape to be
stored, transmitted, compared and recognized. These features must
be independent of translation, rotation and scaling of the shape. A
approach is proposed to obtain high performance, efficiency and to
merge the boundaries into sequence of straight line segments with
the fewest possible segments. Evaluation on the performance of the
proposed method is based on its comparison with established method
of object shape description.
Abstract: This study investigated the presence of polycyclic
aromatic hydrocarbons (PAHs) in the sediments of the Musa Bay
(around the PETZONE coastal area) from Feb 2010 to Jun 2010.
Concentrations of PAHs recorded in the Musa Bay sediments ranged
from 537.89 to 26,659.06 ng/g dry weight with a mean value of
3990.74 ng/g. the highest concentration of PAHs was observed at
station 4, which is located near the aromatic outlet of Imam
Khomeini petrochemical company (station 4: BI-PC Aromatic
effluent outlet) in which its concentration level was more than the
NOAA sediment quality guideline value (ERL= 4022 ng/g dry
weight). Owing to the concentration of PAHs in the study area, its
concentration level was still meet the NOAA sediment quality
guideline value (ERL: 4022 ng/g dry weight); however, according to
the PELq factor, slightly adverse biological effects are associated
with the exposure to PAHs levels in the study area (0.1< PELq= 0.24
> 0.5).
Abstract: In this paper, a new recursive strategy is proposed for determining $\frac{(n-1)!}{2}$ of $n$th order diagrams. The generalization of $n$th diagram for cross multiplication method were proposed by Pavlovic and Bankier but the specific rule of determining $\frac{(n-1)!}{2}$ of the $n$th order diagrams for square matrix is yet to be discovered. Thus using combinatorial approach, $\frac{(n-1)!}{2}$ of the $n$th order diagrams will be presented as $\frac{(n-1)!}{2}$ starter sets. These starter sets will be generated based on exchanging one element. The advantages of this new strategy are the discarding process was eliminated and the sign of starter set is alternated to each others.
Abstract: Caching was suggested as a solution for reducing bandwidth utilization and minimizing query latency in mobile environments. Over the years, different caching approaches have been proposed, some relying on the server to broadcast reports periodically informing of the updated data while others allowed the clients to request for the data whenever needed. Until recently a hybrid cache consistency scheme Scalable Asynchronous Cache Consistency Scheme SACCS was proposed, which combined the two different approaches benefits- and is proved to be more efficient and scalable. Nevertheless, caching has its limitations too, due to the limited cache size and the limited bandwidth, which makes the implementation of cache replacement strategy an important aspect for improving the cache consistency algorithms. In this thesis, we proposed a new cache replacement strategy, the Least Unified Value strategy (LUV) to replace the Least Recently Used (LRU) that SACCS was based on. This paper studies the advantages and the drawbacks of the new proposed strategy, comparing it with different categories of cache replacement strategies.
