    In this work, the influences of different concentration of sodium hydroxide (NaOH) (3, 6 and 9 wt.%) on the flexural and impact properties of linear low-density polyethylene / date seeds (LLDPE/DS) composites were examined. The LLDPE / DS ratio was fixed at 90/10 wt.% and the size of DS particles was measured at 125 - 250 micro m. The process used to synthesize the composites id extrusion followed by injuction molding process. Results showed that the presence of NaOH particularly at 6 wt.% concentration has improved the flexural and impact properties of the composite. This is due to bonding of the date seeds particles with the LLDPE matrix that reflected posativelly on the mechanical properties of the composite. However, the using of high NaOH concentration (9 wt.%) has shown an opposite trend, the increasing of surface roughness of the fiber after 9% NaOH treatment has reduced the flexibility of the composite and made it stiffer and more rigid, which in turn made it easy to break during mechanical test.

    Tracking the heritage building changes has been a primary concern in an architectural works, as the building features may transformed due to periodic of time. In addition, the perseverance of heritage buildings seems taken lightly due to the eagerness of the Malaysian architect in designing urban anxious architectural features for the new building development. Therefore, in order to preserve the delicate features in heritage building; the development of an 'As Built Drawing' (ABD) is crucial. Plotting the ABD has several laidback which includes the reachability of the human to measure the building on site. Hence, technology acceleration using Unmanned Aerial System (UAS) has provided an instrument to develop ABD without risking human's lives. Prior to development of ABD, there are several challenges in the implementation, specifically on the photogrammetry area. The photogrammetry phase in this research is crucial, as the ambiguous imaging captured can caused the misrepresentative Building Modelling replication. Therefore, the research aims to identify the imaging challenges during the progression of producing the ABD using UAS technology. With aid of the 3D Laser Scanner, the instrumental parameters have been set up, and data were recorded. On field data were collected in heritage building in Masjid Alwi Kangar. The ABD has been produced and the challenges arose from the implementation were bountiful to discuss. The research found that, the imaging challenges were the imperative parameters to tackle in order to score the accuracy in producing ABD using UAS technology.

    Coal and coal-fired power plants are crucial for supplying global energy demand. However, coal-fired power plants produce significant quantities of bottom ash as by-products. Through these power plants, it produces approximately 18 tons of bottom ash each day. Malaysia has the challenging task of dealing with an increasing amount of waste generated by power plants each year. The high cost of construction and operation of incineration plants coupled with a lack of landfills have given rise to the need for waste minimization and recycling. The use of coal ash in concrete is a new dimension in concrete mix design and if applied on large scale can revolutionize the construction industry, by economizing the construction cost and decreasing the ash content. The used of the coal bottom ash in the concrete brick can reduce the wastage of the coal bottom ash in Malaysia, beside that the cost of the housing can be reduced. In addition, the sustainability in the housing construction in Malaysia can be achieved using the wastage material in the construction.

    This work evaluated the effect of different loading and size of date seeds (DS) on some mechanical properties of LLDPE/DS composites. Three different size (125 - 250 mm, 250-500 mm, and 500 - 1000 â–¡m) and four different size loading (5, 10, 15, 20 wt%) of DS were used in this work. Flexural and Impact properties were evaluated when DS added to the LLDPE/DS composites. In order to fabricate this composite, the extrusion process followed by injection molding process was used respectively. It is found that the Flexural strength and Flexural modulus decreased with the increasing of date seeds loading in the composites. Furthermore, the Flexural properties of the composite with a coarser size of DS reduced more than other size of DS. The results of the impact strength testing have shown a similar trend of flexural properties. The LLDPE/DS composites at high DS loading show low impact strength (IS) value. Furthermore, the DS coarser size shows lower impact strength than other DS size. The reduction of the mechanical properties in the composites was probably due to the lack of a suitable coupling agent system need to be used to improve the adhesion bonding between filler and matrix.

    Road and highway observation is critical for road engineers to determine the information of the highway itself for the needs of maintenance, rehabilitation and even in construction. This research reviews the efficiency of information of roads and highway by visual and experience. The mean of visual includes the usage of Unmanned Aerial Vehicles (UAV) and on spot observation. It also reveals the image based, photogrammetric and stereo-vision, and mobile mapping systems.The software output has compatibility with known CAD/GIS packages to widen its scope of applications. Methodologies, examples and demonstration related to the use of the developed software and laser scanning data in road mapping for a case study are described. The results showed the flexibilities of the developed software and the proposed method for generating the necessary maps and data for road distresses such as longitudinal cracks, transverse cracks, patch deterioration, potholes, and ravelling. However, the present work shows that using terrestrial laser scanning technologies for modelling the road surface has advantages such as surveying speed, big roads, highways and tunnels. Also it provides the safety for surveyors and the absence of a disruption to traffic. The developed software and methodology are suitable for universities, academic centres and are of great interest to small engineering firms for the generation of road surface maps.
