A parametric study of DMS subjected to induced low-stress consolidation and heat treatment

Dredging activities are important either in the control the accessibility and navigability to harbours or the maintenance to the existing facilities. Dredged marine sediments (DMS) is the products generated from dredging activities. DMS consists mainly of clays, silts and sand mingled with rocks, debris, larger obstacles and organic matter such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated aromatic biphenyl (PCBs

The impact of word of mouth on consumer purchase intention for smartphone / Tuan Farah Azlinda Tuan Ismail

The purpose of this study is to determine the impact of WOM towards purchase intention for smartphone among youth generations. The research is based on a sample of 135 respondents. The result show that source attractiveness variables have significant influence on purchase intention for smartphone among youth generations. It involves the process of conducting the research such as in determining the sample, the reliability and validity of questionnaire and including the research design, sampling technique, data collection method also involving primary data, secondary source and data analysis technique. Word of mouth or known as WOM is defined as a new marketing tool in the hands of marketers emerging in the digital age that can be effectively leveraged to achieve the desired consumer groups and influence consumer attitudes effectively and it could generate a large amount of revenue. The main objective of this study is to determine whether the factors (ie: source credibility, source expertise, source attractiveness and social tie strength) have impact on consumer purchase intention for smartphone. The strongest relationship can be identified is between source attractiveness and purchase intention among youth generations

The characterization of recycled concrete aggregate as filter in removal of phosphorus

Phosphorus (P) is one of the key nutrients that lead to eutrophication problem in surface water. However, the existing conventional wastewater treatment system to remove phosphorus is expensive and require a complex process. Therefore, a system using low cost and environmental friendly should be practiced to overcome this problem. Recycled concrete aggregate (RCA) used as a filter system emerged as an alternative technology for phosphorus removal. This can overcome the problem of construction site waste by converting the waste into something valuable products. Thus, this study aim to investigate the physical and chemical characteristic of RCA that influenced adsorption of P. RCA was analyzed using Scanning Electron Microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX) testing to determine chemical composition. Results shows that RCA is highly contained with Aluminium, Calcium and Magnesium elements that enhanced the Phosphorus adsorption

Development and field testing of Geocomposite Cellular Mats (GCM) to minimize the ground movements of highway embankments founded on peat ground

Challenging grounds are often met in planning, design and construction of highway embankments which as a consequence succumb to undesirably excessive ground movements. Such ground conditions can range from unforeseen cavernous grounds to soft compressible organic soils of variable depths. Often alternate route planning is not feasible, and if necessary alternative construction procedures are not adopted, the net result will be unwanted roads user discomforts such as bumpy roads or even fatal road collapse. Highway constructions norms to circumvent such occurrences are to replace with alternative transported foundation soil/ground improvement or use an appropriate form of geo mats. Hence, this paper presents an alternative and innovative lightweight fill material: Geocomposite Cellular Mat (GCM) used to minimize the ground movements of highway embankments over peat ground. The conceptual development of a stiff mat structure but with a weight lighter than the embankment fill soil is described. The material used for the stiff mat is environmentally friendly in utilizing recycled plastic and its structure, enabling the free movement of water to dissipate any excessive porewater pressures. The performance of theGCMwas appraised under field trial conditions on a test site in Parit Nipah, Johor, Malaysia. The site comprised of a vast expanse of hemic peat and environmental conditions at the test site were fully monitored. The geotechnical properties of the peat at Parit Nipah were typically high organic matter content (~85%), high moisture content (>600%) and very low undrained shear strength (<15 kPa). Details of the set up and layout of the trial embankments tested are fully described, and the techniques adopted to get a comprehensive narrative of the settlement characteristics using innovative measurement techniques are also described. The performance of the GCM incorporated embankment was compared with that of a similar embankment that was formed of conventional backfill (sand fill). The findings show that the field ground movement observations confirmed that themaximum settlementswere reduced by up to 84% with the GCMfills.Moreover, the differential settlements were reduced by up to 70%

Comparing forecasting effectiveness through air travel data

Airline traffic forecasting in the medium term is important to airlines and regulatory authorities that attempt to plan and schedule capacity. This study examines a number of alternative approaches to forecasting short to medium term (1 to 3 years) air traffic flows. The data examined are flows between the UK and six other countries over the period of 1961- 2002, which has seen substantial changes in both transport technology and economic development. The economic drivers, under consideration, are price, income and bilateral trade. The forecasting models employed include autoregressive models, autoregressive distributed lag models specified using various statistical and economic criteria and a newly developed automatic method for model specification(PcGets), as well as time varying parameter models.Various approaches to including interactions between the contemporaneous air trriffic flows are examined including pooled autoregressive distributed lag models and the inclusion of a 'world' variable that measures overall trade growth in the world economy. Based on the analysis of forecasting error measures, it is concluded that time varying parameter models that include the 'world' variable with an average error of around 2.5% outperform alternative forecasting models. This is perhaps explained by the dramatic structural changes seen in the air traffic market

House Of Silver Mobile Application (HOSAPP): Embrace The Art Of Silver Handicraft

“To know is to love”, it is a best idiom to illustrate the need of awareness creation in attracting attention towards a subject. As such, this project focused on the study, design, development and deployment of mobile application as a medium to create an awareness and further attraction toward House of Silver; a niche retailer of silver handicraft. In addition, as cited by Lavidge and Steiner in an article entitled “A Model for Predictive Measurements of Advertising Effectiveness”, effective marketing is to create the awareness of the product. As it is, House of Silver has a hard time to market and attract buyers due to lack of silver-value knowledge among current consumers. Therefore, the objective of this project is to solve the above mentioned issue by utilizing the use of mobile application in creating consumer awareness and attraction toward House of Silver merchandise

Algorithmic approaches in model selection of the air passengers flows data

Algorithm is an important element in any problem solving situation.In statistical modelling strategy, the algorithm provides a step by step process in model building, model testing, choosing the ‘best’ model and even forecasting using the chosen model.Tacit knowledge has contributed to the existence of a huge variability in manual modelling process especially between expert and non-expert modellers.Many algorithms (automated model selection) have been developed to bridge the gap either through single or multiple equation modelling.This study aims to evaluate the forecasting performances of several selected algorithms on air passengers flow data based on Root Mean Square Error (RMSE) and Geometric Root Mean Square Error (GRMSE).The findings show that multiple models selection performed well in one and two step-ahead forecast but was outperformed by single model in three step-ahead forecasts
