MODELLING OF NONLINEAR SYSTEMS USING INTEGRATED OBFARX PLUS NEURAL NETWORK MODELS

The objective of this project is to develop a new model, which is by combining OBFARX linear model with nonlinear NN model. The results obtained will be compared with the previous models to show performance improvement by the new model. The new model development is based on the model developed by (Zabiri et al 2011) which is OBF linear model combination with nonlinear NN model. The OBF-NN model cannot work efficiently on some problems due to the limitations of the OBF part of the equation. So it is important to analyze the new model which is OBFARX-NN with OBF-NN model. The scope for this project will be the development of the parallel OBFARX-NN model, methods for estimating the model parameter, simulation analysis using MATLAB and evaluation on OBFARX-NN model performance. The method for completing the project will be firstly, make sure all the necessary information about the individual model is available. Then develop a theoretically working OBFARX-NN model. After that, analysis of the performance of the created model is done and also alterations here and there for better clarification. All in all, the result are the improve performance of process control by OBFARX-NN model compared to OBF-NN model.The most important aspect of the model development is the extrapolation capabilities of the model itself. When a model is forced to perform prediction in regions beyond the space of original training, then it can be said that the model can function well even when the process parameter is changed. This aspect is very important because in practical plant, the process conditions are continually changing making extrapolation inevitable. Thus, by testing the extrapolation capabilities of the OBFARX-NN model, the project had come up with the subsequent RMSE value and compared with previous model. The RMSE value indicates superior performance in the extrapolation region

Walkability Design for Urban Public Housing Park

The walkability approach is essential to ensure the connectivity among space in the urban area. The design should be appropriate, safety, maximize and capable of reaching every inch of the spaces, just by walking. Good connectivity must allow people to walk freely and accessible in many ways. People have great chances to meet each other or having potential outdoor activities without any challenges. This study aims to measure the user perception of the existing spaces in the urban public housing environment that been covered and uncovered with the walkability linkages. The objectives of this study are to identify the existing pedestrian linkages in the study area; to investigate the user perception of the existing walkability system in the study area, and finally to conclude and provide a better solution for better walkability opportunity among residents to access the public park.© 2016.

Youth in Vertical Housing Neighbourhood Space: A Focus Group Discussion

Focus group discussion series was set up at the vertical housing of Kerinchi People Project Housing, Lembah Pantai with two different group in separate venue and time. The analysis was done by using Atlas.ti after transcribing and coding the audio-taped of discussion, searching for networking on youth participation. The finding shows youth demandingly indoor space compared to outdoor space due to open space inadequacy and absence of space quality yet lost the sense of belonging. Furthermore, the residents' committee neglected youth participation in decision-making process or meeting with the committee, has resulted from youth not to actively participate in the community

The Importance of Public Library for Youth Development in Malaysia

The purpose of this paper is to examine the usage of public library towards youth development. Generally, a public library offers information and educational resources to a community. Being that in the modern world, there are other modes in seeking information, the public library is often disregarded and being ignored of its existence. Factors that affect the use of public library such as accessibility, availability, comfortability and the maintenance of it plays an important role in determining its usage among youth. The paper will look into four research areas of the urban and rural areas involving 800 respondents (youth) in Malaysia as the base of this study to see whether the public library is used by the youth to gain information apart of other resources available.Keywords:Public Library, Youth, Youth development.ISSN: 2398-4287© 2017.

Detection of organochlorine compound in puyu, sepat and haruan fish caught from irrigation canals in paddy fields in Selangor and Perak, Malaysia

A case study was conducted to investigate the concentration of organochlorine pesticide residues in fish samples collected from irrigation canals in paddy fields in Tanjong Karang and Sekinchan, Selangor and Seberang Perak, Perak, Malaysia. The samples comprised of three fish species, namely puyu (Anabas testudineus), haruan (Channa striatus) and sepat (Tricogaster pectoralis). Samples were chopped and homogenized and later digested and extracted using QuEChERS method and characterised for organochlorine compounds using gas chromatography. Seven organochlorine compounds, namely aldrin, dieldrin, endrin, endosulfan, o,p-DDT, o,p-DDD and p,p-DDT were identified and quantified. The water samples taken from the irrigation canals were analysed only for endosulfan at 0.04 mg/kg, which exceeded the maximum residue level for endosulfan pesticide residue for water sewage by Environment Protection Administration of the Republic of China on Taiwan (2000) at 0.03 mg/kg. However, the concentrations of endosulfan in all fish samples were below the Codex Alimentary Maximum Residue Limit of 0.2 mg/kg for meat

Youth in Public Housing: Place attachment and Quality of Life Index

This study examines the quality of life (QoL) satisfaction through place attachment theory upon neighbourhood area among youth in Kuala Lumpur. The objectives are to test the impact of neighbourhood sense of place on QoL index. For place attachment, the environmental factors closest to the home of the residents exerted a greater influence than the more distal factor. These findings contribute to understanding the relationship between place attachment theory and quality of life among youth. The discussion also considers personal dimensions of place belonging and identifying associations amongst them as ways to explore youth quality of life in the PPH.  Keywords: Quality of Life; Place Attachment Theory; Youth; Public HousingISSN: 2398-4287© 2017.

A Mixed-Method Research on Recreation Space for Youth in Malaysia

This research applied a mixed-methods analysis of the recreation space for youth in Malaysian urban and rural areas applying both the qualitative and quantitative approach. For qualitative research, four (4) focus group discussions (FGD) with 24 youth and 22 stakeholders have conducted while for quantitative research, a total of 800 youth selected as respondents. The quantitative research questionnaire based on the outcome of the FGD. The results found that the provision of recreational space in urban and rural areas including location, adequacy ratio, current condition, proximity, accessibility and level of maintenance required to reviewed for improvement.

Relationship between body weight and linear body measurements in boer goats.

Fifty-five Boer goats from a private farm located at Kg Pulau Meranti, Mukim Dengkil, Puchong, Selangor was sampled to examine the relationship between body weight and linear body measurements (body length, height at withers and heart girth). The goats were of four age groups: Group 1 (4-12 mo), Group 2 (13-18 mo), Group 3 (19-24 mo) and Group 4 (25-36 mo). Body weight and linear body measurements (body length, height at withers and heart girth) were taken during a 7-d period in December 2010. The body weight and linear body measurements were not significantly (p>0.05) different between male and female goats but were significantly(p<0.05) different among age groups. Male goats were heavier in weight, longer in body length, taller in height at withers and larger in heart girth compared to the female goats. Pearson’s coefficient of correlation showed positive, high and significant correlation between body weight and linear body measurements and also among the body measurements.A simple linear regression equation with a high coefficient of determination (R² = 0.948) using heart girth to predict body weight of Boer goats was also derive
