An Application of Proposed Ridge Regression Methods to Real Data Problem
Authors: Shariff N S M , Duzan H M B 
Published: April 2019

The Ordinary Least Squares (OLS) is a common method to investigate the linear relationship among variable of interest. The presence of multicollinearity will produce unreliable result in the parameter estimates if OLS is applied to estimate the model. Due to such reason, this study aims to use the proposed ridge estimator as linear combinations of the coefficient of least squares regression of explanatory variables to the real application. The numerical example of stock market price and macroeconomic variables in Malaysia is employed using both methods with the aim of investigating the relationship of the variables in the presence of multicollinearity in the data set.Â The variables on interest are Consumer Price Index (CPI), Gross Domestic Product (GDP), Base Lending Rate (BLR) and Money Supply (M1). The obtained findings show that the proposed procedure is able to estimate the model and produce reliable result by reducing the effect of multicollinearity in the data set.

Published: April 2019

This paper assesses of recycled concrete aggregates as a filter for removal of phosphorus in synthetic wastewater. Recycled concrete aggregate 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 determine the percentage of Phosphorus removal by using two different size of Recycled Concrete Aggregate which is (5 mm to 10 mm) and (25 mm to 30 mm). A total of five vertical recycled concrete aggregate filter laboratory scale was design using recycled concrete aggregate and five different concentration of synthetic wastewater which is 10 â€“ 50 mg/L was prepared. Samples were taken from the influent and effluent filters to be tested once a week, and analyzed to determine the value of pH and the percentage of Phosphorus removal (%). 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. The RCA with size 5 mm to 10 mmÂ and synthetic wastewater 10 mg/L display high potential in removing Phosphorus with 99.54% removal at pH 9.77. The lower concentration of synthetic wastewater, smaller size of RCA and higher pH have slightly better Phosphorus removal efficiency. Thus, RCA has a potential in removing Phosphorus from synthetic wastewater.

Optical temperature sensors gain interest from the community recently due to their immunity to electromagnetic interference and ruggedness against chemical and mechanical disturbances as opposed to the conventional temperature sensors such as thermocouples and resistance temperature detectors. Optical temperature sensors come with many varieties and Sagnac interferometer is one of them. In this work, an all-fiber temperature sensor is proposed and experimentally demonstrated. The proposed optical temperature utilizes Sagnac interferometer as the temperature head. The underlying mechanism for this sensor is based on the temperature dependence of a polarization maintaining fiber (PMF) in the Sagnac interferometer. The PMF birefringence which is influenced by temperature affects the phase difference of two incoming lights that enter the Sagnac interferometer and this contributes to the shifting of the transmission spectrum. The input light for the sensor characterization is provided by a custom-made amplified spontaneous emission source which comprises of a tunable laser source, a 980 nm laser diode pump, a wavelength division multiplexing coupler and a 10 m long erbium-doped fiber. Experimental results indicate that the temperature does affect the PMF characteristic.Â As the temperature increases from 30Â°C to 45Â°C, the wavelength dip reduced from 1553.8 nm to 1536.78nm. This proposed optical temperature sensor has a sensitivity of-1.0345 nm/Â°C. The development of this optical temperature sensor is promising especially for the measurement in the harsh environment.

The main aim of the present work is to study the effect of heat enhancement method on the cooling process of a spherical dimple profile. It was prominently known that introducing dimples configuration causes an enhancement in heat transfer over a surface.Â In this project, an experimental investigation was carried out to examine the cooling effect of the spherical dimple profile during steady laminar flow in a wind tunnel. Seventeen different sets of parameters related to dimple diameter (mm), dimple orientation (angle) and air stream velocity (m/s) were studied. The Box-Behnken of Response Surface Methodology (RSM) was used as design of experiments (DoE) tool to evaluate these parameters on cooling time. This work deals with the analysis of variance (ANOVA) in order to establish the significant effect of input parameters. The result reveals that an increase in dimple diameter and air stream velocity increase heat dissipation. The shortest cooling time of 7 minutes can be achieved when the dimple diameter is 12 mm; the dimple orientation is 60Â° and air flow velocity at 18 m/s. The mathematical model has been rendered where the model has been experimentally validated with the average error of 6%.

The demand for edible oil from all over the world has generated a huge amount of solid waste. Due to that, the problem of disposal method has become a constraint by the authorities. Therefore, this study is focusing on the incorporation of palm kernel shell (PKS) into fired clay brick in terms of indoor air quality assessment. The brick was incorporated with 0% and 5% of PKS and fired at 1050Â°C with heating rates of 1Â°C/min. Preliminary analysis was conducted with X-Ray Fluorescence test to determine chemical composition of raw materials used in the study. A further experiment of indoor air quality was obtained by measuring gases emission of total volatile organic compound (TVOC), carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), formaldehyde (HCHO) and particulate matter (PM10) in Walk in Stability Chamber with controlled temperature and relative humidity. All parameters were compared with Industry Code of Practice on Indoor Air Quality standard.Â The result shows that incorporation 5% of PKS into fired clay brick complied with the standard requirement for use as building materials. As the conclusion, the use of palm kernel shell as clay replacement could reduce the waste disposal in landfills whilst providing low-cost building materials.

Published: April 2019

Food waste is a global issue with environmental, social, and economic consequences. The problem with food waste has become more and more evident during recent years and a reduction of the waste would be one important step towards a more sustainable society. Food waste is a global issue with environmental, social, and economic consequences. As fast food industry strives to develop distinctive identities, deeper understanding about topics such as brand identity, meaning, image, and reputation will enable brand owners to communicate more effectively with stakeholders including shareholders, customers, employers, and others. Many studies have focused on investigating the sources of food waste from households, while very little is known about other outlets such as food plants and restaurants whose services contribute to the food waste amounts. The study was conducted through a literature review and interviews with the actors that included 3 QSR fast food restaurants management and 1 official from AYAMAS Food Corporation Sdn. Bhd. To broaden the scope of the research several supporting frameworks were utilized and aided in the generation of a complete understanding of the thoughts of the actors. The results from the research showed a variety of the actions they have taken to address the issue, and the opportunities and obstacles they see for the management of food waste. However, the environmental, economic, and social dimensions of the issue were acknowledged by the interviewees, being the latter the most relevant one for them, stating the importance of a change in behavior and raising of awareness and consciousness from all people towards the issue.Â Â

This study was implemented to identify the specific factors that lead to major contribution of floods in Klang River Basin. A thirty-year (1987-2017) database obtained from Department of Irrigation and Drainage (DID), the selected data was analyzed by using integrated Chemometric techniques. The finding from Correlation Analysis revealed strong correlation between stream flow and water level is more than 0.5 (= 0.799). The finding from Principal Component Analysis proved that the selected parameters were significant with the result of R2 > 0.7was applied as a main tool for further analysis. Based on the result, it revealed that stream flow and water level were the most significant hydrological factor that influenced flood risk pattern in Klang River basin. Based on the result from Statistical Process control (SPC), the finding showed that the Upper Control Limit (UCL) for water level was 30.290m. The plotted data which is more than 30.290 m can cause flood to occur in Klang River Basin. Thus, it is very important to continuously monitor and maintain the mitigation measure of flood in the study area to avoid flood to occur. This study also helps to provide visualization of flood pattern and show the optimal rates for the maximum limit for flood control in Klang River Basin.Â Â

This article investigated the general compositions of the areas (the road) including the geology, mineralogy, and geochemistry to explore the reason for the road failure. The zone is underlain basement (storm cellar) and sedimentary rocks of different textures, mineralogy, and geochemistry. The results implies that the areas that is most stable along the road portions is underlain by the granite-gneiss, granites, amphibole schist and quartz, schist and small sandstone while portions with the failures are underlain by mica schist, phyllite, and coarse-grained granite. It is apparently sure from this study that poor quality metasedimentary rocks constitute the formation of the failed portions. However, the high numbers of the sediment and sandstone present in the area that can easily be weathered due to the climate variation have increased the failure. In conclusion, the result will help the engineers during reconstruction of these parts need to be excavating deeply and replace with granite-gneiss, granites, amphibole schist and quartz for better result.Â Â

Published: April 2019

The hotel industry has remained one of the most competitive industries in the 21st century, and there is a great deal of study being done on guest satisfaction and the consequent effects it has on guest loyalty and financial performance. Many studies have demonstrated that hoteliers that have more satisfied guests experience higher guest loyalty and perform better financially compared to their competitors, ensuring continuity of their business in the long term. The overwhelming demand for quality products and services among Muslim travelers in recent years has led to the establishment of Muslim Friendly Hotels (MFH) in Malaysia and other Muslim countries. It is widely believed that Muslims perceive Islam as something more than just a religion - it is a way of life. Hence, the religion shapes their consumption behavior even during travel. Currently, very little research has examined the influence of satisfaction on revisit intention among guests staying at MFH, specifically in Malaysia. Preliminary findings from a survey of hotel guests indicate that there is a significant relationship between guest satisfaction and revisit intention, which further explains the importance of desirable hotel attributes in influencing hotel selection and a guestâ€™s experience.Â Â

Published: April 2019

The introduction of Aerotourism using Unmanned Aerial Vehicle (UAV) is timely due to the importance of strong, positive destination image and how it works to influence tourist destination selection and satisfaction, as well as destination sustainability. UAV has certain advantages over piloted aircraft missions, which include the lower operating cost, improved safety, flexibility in mission planning, less expensive remote sensing platform, more rapid deployment capability than piloted aircraft and closer proximity to the target requirement.Â The increasing trend of UAV (fixed wing and rotorcraft) as part of image capturing and live telecasting has prompted many tourism operators to migrate into this autonomous technology. Unfortunately, due to its restricted design configurations and requirements related to fixed wing and rotorcraft UAV such as the need for landing strip and long endurance has receded the ultimatum usage of this technology. This paper aims to develop a conceptual framework of Aerotourism for destination image enhancement, as well as addresses the conceptual approach of Hybrid UAV (hUAV) by integrating fixed wing with rotorcraft. It is predicted that this enabling technology will achieve the smooth transition from hover to cruising and the realization of Aerotourism in Malaysia. This research could be considered as a breakthrough for Malaysian destination image, thus it could further boost the tourism industry in Malaysia.Â Â

Published: April 2019

This paper aims to understand the role of homestay programme development as a medium for community-based tourism in rural areas. Although many homestay businesses are actively run by the local community, the sustainability of the development is questionable. Attributes from previous research of local communitiesâ€™ attitude were reviewed and linked to construct a conceptual framework within the scope of homestay tourism. This study is deductive in nature where descriptive analysis is used to generate mean values of the variables. Four variables were tested: financial resources, infrastructure resources, community participation and community empowerment for the mean values. This finding can be used in determining sustainable tourism practice which will be focused on economic, socio cultural and environmental pillars. The descriptive statistical analysis reveals that the community is heavily participating in tourism activities in their village; however, they are not genuinely empowered. Apart from that, financial and infrastructure resources are not in good state and require improvement.Â Â

Published: April 2019

This research integrates information from both environmental and social sciences to inform effective management of the wetlands. A three-stage research framework was developed for modelling the drivers and pressures imposed on the wetlands and their impacts to the ecosystem and the local communities. Firstly, a Bayesian Belief Network (BBN) was used to predict the probability of anthropogenic activities affecting the delivery of different key wetland ecosystem services under different management scenarios. Secondly, Choice Experiment (CE) was used to quantify the relative preferences which key wetland stakeholder group (aquaculturists) held for delivery of different levels of these key ecosystem services. Thirdly, a Multi-Criteria Decision Analysis (MCDA) was applied to produce an ordinal ranking of the alternative management scenarios accounting for their impacts upon ecosystem service delivery as perceived through the preferences of the aquaculturists. This integrated ecosystem management approach was applied to a wetland ecosystem in Setiu, Terengganu, Malaysia which currently supports a significant level of aquaculture activities. This research has produced clear guidelines to inform policy makers considering alternative wetland management scenarios: Intensive Aquaculture, Conservation or Ecotourism, in addition to the Status Quo. The findings of this research are as follows. The BBN revealed that current aquaculture activity is likely to have significant impacts on water column nutrient enrichment, but trivial impacts on caged fish biomass, especially under the Intensive Aquaculture scenario. Secondly, the best fitting CE models identified several stakeholder sub-groups for aquaculturists, each with distinct sets of preferences for the delivery of key ecosystem services. Thirdly the MCDA identified Conservation as the most desirable scenario overall based on ordinal ranking in the eyes of most of the stakeholder sub-groups. Ecotourism and Status Quo scenarios were the next most preferred and Intensive Aquaculture was the least desirable scenario. The methodologies developed through this research provide an opportunity for improving planning and decision making processes that aim to deliver sustainable management of wetland ecosystems in Malaysia.Â Â

Published: April 2019

The importance of sustainability reporting for companies to be able to know the role of the company in disclosing social responsibility and the implementation of corporate sustainability as a manifestation of corporate governance mechanisms, company size and financial performance. This study uses a stratified random sampling method for companies that have revealed sustainability reports and those that do not disclose sustainability reports. The research method uses logistic regression, with a sample of 13 non-financial companies listed on the Indonesia Stock Exchange. Based on the results obtained, it can be seen that the mechanism of corporate governance consisting of independent commissioner variables has a negative influence on sustainability reporting, institutional ownership variables have a positive influence on sustainability reporting, managerial ownership variables have a negative influence on sustainability reporting, audit committee variables have a negative effect on sustainability reporting, the variable size of the company gives a negative influence on sustainability reporting, and financial performance variables which are leverage variables have a negative influence on sustainability reporting.Â Â
