A fabrication of high performance heat sink composite material made of copper matrix reinforced by multiwalled carbon nanotubes (MWCNTs) up to 2.5 Vol. % using powder injection molding technique (PIM) has been done successfully. A mixture of Cu/MWCNTs was compounded using a Z-blade mixer for homogenous dispersion of solids in the binder. The flow properties were measured using a capillary rheometer in the shear rate range which expected to occur during metal injection molding. To avoid binder degradation, TGA test was carried out. The TGA results showed that the processing temperature such as mixing and injection molding should be lower than 170°C. The injection molding was carried out at low pressure. A combination of solvent and thermal debinding was used for binder removal from the samples and then the sintering process has taken place in argon gas at 900°C. The results show that the sintered samples experience isotropic shrinkage around 21% with 14% weight loss and the density of the composites was decreased after sintering process.

Numerous accidents have happened in all types of moored units, permanent and mobile. The problems related to mooring system failures are collision, abrasion, anchors etc. These problems have impact on people, environment, assets and reputation of the company. The objective of this paper are to determine the frequency of failure, to categorize severity of failure of mooring system and to rank the particular hazards by dividing the dimensions of frequency and severity into risk matrix. This work proposes HAZOP (Hazard and Operability) analysis to evaluate risks related to accidents in mobile mooring system. In qualitative assessment the accident risk level and acceptance criteria were established through a scoring system. The result of this methodology can be used to prevent future damage and aid to set a priority of maintenance based on hazards ranking.

Driving on roads nowadays has a lot of limitations. Traffic congestion is increasingly happening especially at the urban areas because of the increasing population & urbanization. Accordingly, the traffic flow is not being run properly (vehicles delay & traffic congestion) and reduces the throughput at the intersections. In this paper, We suggest a system architecture serving as Intelligent Transportation Systems (ITS) to overcome the road limitation resultants. The proposed system design, Initially, has five main devices which would co-operate together to provide safety, assistance, and comfort for the drivers. By applying this system on roads, researcher would have an opportunity to create more protocols and algorithms improving traffic flow, safety, and comfort of driving. A chosen application (Improving intersection traffic flow) results were obtained from simulation studies, are compared with our system to show the significance or the need for the proposed system and its protocol's control actions and strategies.

This paper investigates the low temperature thermochemical treatments in conventional tube furnace of hybrid treating which introduce nitrogen and carbon simultaneously with the aim to improve surface properties of austenitic AISI 316L and Duplex 2205 stainless steels. The expected resulting layer is a structure termed expanded austenite which is supersaturated with nitrogen and carbon and this structure are responsible to the higher hardness and better wear properties without impairing its corrosion resistance. Characterization of this expanded austenite layers have performed including Line scan elemental analysis, SEM and SPM were used to reveal the characters of the produced thin layers. Elemental profile of nitrogen and carbon across the hybrid treated layer were obtained by line scan mode EDS-SEM.

The Kinta Valley is bounded by granite ranges. The extant vestige limestone hills which dot the valley mainly formed by the rivers arising from the granite. In order to determine the denudation rate of the Kinta Valley, sound assumptions and estimates of volume, area and time were taken. A 2 mm/ka denudation rate is found, although it underestimates the modern rate measured in the area, and the mean value obtained from tropical karst terrain. In spite of this, the value has been taken as good estimate since it reflects the fluctuation of denudation rate through time, which is possibly caused by factors other than considered in this study. It is inferred that, the realistic estimation of volume and time, presumed for the limestone deposit which has been taken away from the Kinta Valley, enabled to determine the long term denudation rate; nonetheless, to fully comprehend this, reviewing the paleoclimate of the region is indispensable.

Despite of the well documentation of Model Driven Architecture (MDA) technique and the transformation language Query/View/Transformation Relation QVT (QVT-R) that provided by Object Management Group (OMG), we are finding there is no specific description about the execution engine for the QVT-R Transformation Language. In this paper we will try to provide a preliminary overview about the implementation (execution) model of QVT-R Language which we find it looks like prolog language code execution and this last one depends on Warren's Abstract Machine (WAM) to execute its' code.

The quantification of microporosity leads to determine its empirical relationships with permeability and sonic velocity of Miocene carbonate reservoirs. These relationships can be used for a better understanding of the reservoir systems. This study on Miocene carbonate reservoirs of Central Luconia, offshore Sarawak, Malaysia revealed an inverse relationship between microporosity and permeability. Microporosity has its effects on porosity-permeability correlation. The relationship between porosity and permeability of Miocene carbonate reservoirs shows a better correlation when microporosity is deducted from the total porosity of the reservoir. Microporosity in carbonate reservoirs of Central Luconia, affects the elastic properties of the rock. Microporosity reduces the sonic velocity of the carbonate reservoirs. Both P and S wave velocities of Miocene carbonates of Central Luconia, show an inverse relationship with microporosity. Microporosity affects sonic velocity and permeability in carbonate reservoirs and influences the assessment of ultimate recovery of hydrocarbon. Microporosity can occur in grain, cement or matrix and it is related to the diagenetic history of the carbonate reservoirs.

Boron compounds are widely used raw materials in various industries. However, high boron concentration in aqueous systems may be harmful to both humans and plants. Many treatment technologies have shown wide limitations in the removal of boron from wastewater and boronic wastes due to the complex boron chemistry. Boron exists as boric acid at pH<9.2 but as borate ions at pH>9.2. Recovery of boron is one process that has reduced the harmful effects of boron on both plants and animals especially in areas with boron rich mineral ores like colemanite, ulexite, borax etc. It has also become a new means of boron production and used industrially at a purity of 99%. Many authors have reported successful recovery of boron from different sources in a cost effective ways. This paper reviews the literatures on the applications of boron, its economic significance and the methods of recovery boron.

Abnormality of melanin production causes skin pigmentation disorders. Currently, assessment of treatment efficacy (under Physician's Global Assessment framework) only refers to visual conditions of skin surface and not the condition of the underlying skin layers and pigments. Albeit researches on models and simulations of light interaction with human skin have been reported, none has been specifically developed for pigmentation analysis of melanin types - eumelanin and pheomelanin. Therefore, our research objectives are to develop image analysis of skin pigmentation for classification and quantification of eumelanin and pheomelanin pigment types in human skin. In this research, the model is developed using data collected from clinical study. It is hypothesised that the multispectral approach will provide an accurate characterisation of skin layers to determine melanin types namely eumelanin and pheomelanin. Monte Carlo method is then used to determine skin model parameters such as concentration of eumelanin and pheomelanin.

Natural fibers fulfill most requirements needed to replace synthetic fibers in thermoplastic composites. However, some disadvantages appear when natural fibers are used for composites. The poor compatibility between the hydrophilic fibers with the hydrophobic thermoplastic matrix leads to a weak interface and hence, poor mechanical properties. In this work, the effects of processing techniques (fiber surface modification and varying compounding pressure) on the mechanical properties of rice husk-polypropylene composite were investigated. The results showed improvement in mechanical properties for the treated composites (tensile strength, impact energy and hardness), with the mercerized sample having the highest improvement. The trend of results suggest that there is a need for further work on the optimization of the fiber-matrix interface for improved mechanical properties to be achieved.
