Published: November 2018

Abrasive brushes are often used for surface finishing and deburring and consist of a brush body with fixed, highly flexible abrasive filaments. During the brushing process the highly flexible abrasive filaments deform tangentially and axially and adapt to the shape of the workpiece. The contact behaviour of abrasive brushes in the machining process is very complex and has been insufficiently investigated so far. Abrasive brushes consist of a brush body with fixed, highly flexible abrasive filaments and are often used for surface finishing and deburring. During the brushing process, the highly flexible abrasive filaments deform tangential and axial and adapt to the shape of the workpiece. The mentioned contact behavior of the abrasive brush during the machining process is complex, and has not yet been sufficiently investigated. To better understand the contact behavior and, thus, the brushing process, a model of an abrasive filament is proposed in this study. The model describes the dynamic behavior of a single filament in contact with different workpiece geometries. The filament is discretized into a multi-body system of rigid links connected with rotational springs and rotational dampers, and the workpiece is approximated by using a polynomial. The contact of the multi-body system representing the filament with the surface of the workpiece is described by using Hertz’s theory of elastic contact and Coulomb’s law of friction. Based on this, a system of equations of motion for the multi-body system is obtained by using Lagrangian mechanics. A numerical solution of the equation of motion system was calculated by using experimentally determined material and contact properties of the filament as a composite of a plastic matrix and abrasive grains. A comparison of the calculated results with experimental data yielded satisfactory agreement for the contact between the filament and different workpiece geometries.

In industrial facilities, there are various types of equipment composed of surfaces that have a high degree of freedom. Rotational surfaces and generalized cylinders are often used for equipment handling liquids and gases. In this paper, we propose methods for reconstructing rotational surfaces and generalized cylinders from noisy and incomplete point-clouds captured by a terrestrial laser scanner. In our method, we convert point-clouds into wireframe models and calculate the intersection points with section planes. Then, we extract ellipses from the intersection points on each section plane and reconstruct the rotational surfaces and generalized cylinders using the extracted ellipses. We also propose a method for subdividing a rotational surface into primitive surfaces. We evaluated our method using actual point-clouds of engineering facilities and confirmed that our method could successfully reconstruct rotational surfaces and generalized cylinders.

Today in Japan, comfortable lifestyle and environment realized by abundant electric power is being questioned by energy consumption reduction policies called “cool biz” in summer, and “warm biz” in winter. One reason of these policies is the bad energy consumption efficiency of current air-conditioning systems that cool or warm indirectly human body. Several researches have been investigating the effect of direct human body cooling and warming. However, most proposed solutions focus on direct head or neck cooling, using ice to cool a water circulating system, such temperature during use cannot be controlled accurately nor adapted to user and environment conditions. Recently, a Japanese research team developed a portable system using Peltier elements that can both cool and warm neck. Though cooling was demonstrated to affect positively both physiological and psychological state in summer heat environment, in cold climate it could be confirmed for only neck warming but not feet and hands. In our objective of developing effective energy saving technology for direct temperature-conditioning of human body, and in order to reduce the discomfort caused by body chillness, we have proposed and developed a Peltier element based wrist-mounted wearable device that directly warms human body. A first experimental study showed how wrist warming rhythm affects hyperthermic sensation. Then, we verified whether the thermal sensation of the body, including the extremities, is improved by changing the position where the wrist is warmed.

Burnishing characteristics of a newly developed roller burnishing method were developed. The developed method can effectively control the sliding direction between the roller and a cylindrical workpiece by inclining the roller axis with respect to the workpiece axis. The outer surface of a round aluminum alloy bar was targeted. The influence of burnishing conditions on burnished-surface quality was investigated, and surface quality was evaluated based primarily on the surface roughness, surface profile, and external appearance. As observed, the burnished-surface quality was strongly influenced by the pressing force, roller-inclination angle, and number of tool passes. A superior surface quality could be realized by increasing the number of tool passes.

In recent years, long glass fiber reinforced plastic and carbon fiber reinforced plastic have begun to be used for structural components that require high strength. As a result, thick-walled injection molded products are being manufactured. However, defects, known as voids, are generated inside the molded product and decrease the strength of the molded product, posing a significant problem at molding production sites. The partial compression method, which is a type of injection compression molding, is effective in preventing voids in thick-walled injection molding. However, there have been limited studies that comprehensively investigated the effects of the compression conditions on void prevention in thick-walled injection molding products or the shape and dimension of the molded product, or the issues in the molded product produced by applying compression. The authors have previously proposed the in-mold pressing (IMP) method, which allows the application of partial compression without the use of an injection compression molding machine and verified its validity. In this study, we proposed a compression device in which a servomotor-driven hydraulic pump actuator is used to propel a movable rod to apply compression to the melt inside the mold cavity. The IMP method using this device was applied to mold thick-walled products with thicknesses of 10 mm and greater, and the effects of compression on the generation of voids inside the molded product and the shape and dimensions of the product were investigated. The results indicate that the generation of voids can be prevented by application of this method. In addition, it was found that marginal deformations, which can pose issues, occur in the molded product when compressive stresses generated inside the molded product by compression are released after demolding.

Delamination or fiber out often occurs when machining carbon fiber reinforced plastics (CFRPs) with conventional cutting tools. Moreover, the tool life is short. As a new machining strategy for peripheral finishing of CFRP plates, an oscillating finish grinding process with a woven metal wire (WMW) tool utilizing plunger pump pulsation is proposed in this study. A WMW tool is a type of core drill, but the tool body is made of woven metal wire. A wire mesh and grinding fluid supplied from the inner side of the wire netting are expected to prevent the clogging of CFRP chips on the tool surface. However, the surface machined by the side face of the WMW tool becomes wavy as the wavy side surface of the WMW tool is copied to the machined surface when the rotating tool moves vertically to the tool axis. To overcome this limitation, a tool oscillation mechanism utilizing plunger pump pulsation action was newly developed and applied for finish grinding. As a result, it was demonstrated that the machined surface roughness of the CFRPs was improved through axial oscillation of the WMW tool.

A new methodology to generate instruction commands for real-time machine control instead of preparing NC programs is developed under the CAM-CNC integration concept. A machine tool based on this methodology can eliminate NC program preparation, achieve cutting process control, reduce production lead time, and realize an autonomous distributed factory. The special feature of this methodology is the generation of instruction commands in real time for the prompt machine control instead of NC programs. Digital Copy Milling (DCM), which digitalizes copy milling, is realized by referring only to the CAD model of the product. Another special feature of this methodology is the control of the tool motion according to the information predicted by a cutting force simulator. This feature achieves both the improvement in the machining efficiency and the avoidance of machining trouble. In this study, the customized end milling operation of a dental artificial crown is realized as an application using the new methodology mentioned above. In this application, the CAM operation can be eliminated for the NC program generation, and tool breakage can be avoided based on the tool feed speed control from the predicted cutting force. The result shows that the new methodology has good potential to achieve customized manufacturing, and can realize both high productivity and reliable machining operation.

A method for the estimation of the die release force of die castings of JIS-ADC12 aluminum alloy manufactured through high-pressure die casting was examined. The die release force was evaluated by the strain in the axial direction of the extrusion pin when releasing the die castings. In this research, it was assumed that the factors that influenced the die release force were the thermal deformation of the die and die castings and the reaction layer of Al and Fe generated during the solidification process in the die. These factors in the resistance of the die release were evaluated by the friction coefficient. The die and die castings temperature in the die release process were simulated, and calculation results were mapped onto an FE model, and a coupled analysis of the thermal structure was performed. The calculated value of the mold release force was approximately the same as the actual value, and the friction coefficient was estimated to be approximately 0.5.

The paper analyzes the effectiveness of magnetic resonance imaging with cartilage diagram in diagnosing signs of professional deforming arthrosis of knee joints in miners working in conditions of significant physical loading.

Aim of the research – to determine of diagnostic efficiency of indicators of magnetic resonance imaging of the knee joint and cartilage diagram in miners of the main occupations suffering from deforming arthrosis.

Methods. The research is conducted in 30 miners of basic occupations: 20 mining workers of breakage face (MWBF) and 10 machinists of shearer mining machines (МSMM) have been treated in the inpatient department of occupational pathology of the Lviv Regional Clinical Hospital in 2015-2017 due to deforming arthrosis. Damages of the main anatomical elements of the knee joint with arthrosis were analyzed, visualized initially with the help of MRI, and then - cartilage diagram.

Results. According to the MRI data, in miners of the main occupations with arthrosis of the knee joint the posterior cross-shaped ligament are most commonly affected (in 75.0±9.7 % MWBF and 70.0±14.5 % МSMM), damage to the medial collateral ligament are diagnosed less frequently (in 5.0±4.9 % in the MWBF and in 10.0±9.5 % in the МSMM). On average 3.8±0.4 modified elements of the knee joint are visualized in patients, whereas 4.8±0.1 affected areas are visualized on the cartilage diagram (р<0.05). In 86.7±6.2 % patients, in the analysis of cartilage diagram, changes in all five analyzed areas are diagnosed, indicating a higher efficiency of the diagnosis of changes in the structures of the joint with DA of the professional etiology of the method of cartilage diagram compared with MRI. According to the cartilage diagram the most significant changes are noted in the hypertrophy of the femur: among all miners 62.5±0.3 ms (medial) and 62.6±0.4 ms (lateral), in the MWBF group the average time of Т2-delay is the largest in the area of the medial hypertrophy of the femur is 60.9±2.3 ms, in the МSMM group – in the area of the lateral hypertrophy of the femur: 66.7±3.3 ms, which can be linked to the peculiarities of the forced working position of miners of these professions and the kinetics of joint structures.

These results can be used to diagnose the initial lesions of joint structures with DA of professional genesis, as well as the creation of prognostic models for determining the the degree of risk of development of knee joint damage, which will allow to improve the system of personified approach to diagnostic and preventive measures in working persons in conditions of considerable physical activity and forced working position.

The natural ecosystems are increasingly being replaced by urban built-up area due to fast urbanisation. The urban development pressure brought urban areas to the uncontrolled built environment which, in turn, significantly compromises the quality of public spaces and facilities. Furthermore, the urban environment discourages active living. Thus, research on the relationship between urbanisation and physical health is rapidly coming to the force. Urbanisation can have detrimental effects, particularly on physical health, which further attributed to unsustainable urban development. A study was carried out at Sri Pahang Public Housing (Flat), Kuala Lumpur with the aim to investigate the healthy lifestyle among residents and the relationship with the public facilities available at study area for the physical activity. Data was obtained through questionnaire survey. The relationship between healthy lifestyle particularly the level of physical activity and the facilities in the study area was analysed using correlation test. It was found that most of the respondents were physically inactive and their healthy lifestyle can be related to the planning aspects of facilities in the study area.

Authors: Tahir Zurinah , Abdul Malek Jalaluddin
Published: November 2018

The concept of gated community housing is a feature of contemporary housing development. Housing developers promote this concept through an emphasis on security in gated housing. House owners today favour fenced-in residences, not only for their homes, but also for the entire housing development, including recreational areas and other facilities. The aim of this study is to prioritize the elements of physical security in a gated community housing development. The methodology employed a quantitative approach using the Analytical Hierarchy Process (AHP) in ascertaining the weightage for each element deemed important in the planning of secure gated community housing, with focus on the elements of access, fencing, CCTV installation, lighting, guardhouse and landscape, which are the principal elements that serve to enforce security in the protected community. The results of this study showed that two principal elements, namely access to the property (entry/exit points) and protective fencing, were deemed the most important in providing security in gated community housing. Accordingly, these aspects should be accorded particular attention in the planning of gated communities in the future and be factored into the strategy to enhance security.Gated community housing and guarded neighbourhoods employing such a strategy would be quite effective in providing security to residents.
ILLEGAL HOUSE RENOVATIONS: IMPROVING THE RENOVATION GUIDELINES OF A LOCAL AUTHORITY THROUGH PUBLIC PARTICIPATION
Authors: Sarkom Yazid
Published: November 2018

Illegal house renovations have created numerous problems to local councils in Malaysia. Enforcement work have cost unnecessary financial burden to local councils as well as losses to the house owners. Hence, this research is aimed at investigating the issues associated with illegal house renovations in a local council and exploring the responses from the local council’s stakeholders on the possibility of involving the public in reframing the house renovation guidelines. A qualitative research method of focus group discussion was held among the related stakeholders in Ampang Jaya Municipal Council (MPAJ). The findings indicated that the problems with illegal renovations are mainly due to the unsuitable guideline itself, the level of understanding of the public, the unrestrained small contractors and the complicated enforcement procedures. The council’s stakeholders also agreed that more community involvement is encouraged in restructuring the existing renovation guideline, but not to the extent of giving the public all the rights to decide the final outcome.

Published: November 2018

Learning with nature is a form of psychological therapy for all, including children with disability. Beyond the psychological aspect, access to outdoor green space can also improve social, environmental, developmental, emotional and behavioural, and even medical outcomes. In Malaysia, studies of learning with nature remain scarce due to the Malaysian education system’s focus on indoor learning rather than outdoor learning. This research aimed at determining perceptions towards the application of learning with nature among preschool educators. Qualitative methods were used for data collection, consisting of structured interview and field observation. Four preschools were selected as sample. Results show that learning with nature contributes to the positive development of the children. The approaches used to instil nature awareness include conducive landscape, environmental activities, outdoor class activities, outdoor free play, formal education and recreational programme outside a preschool. These involved both outdoor and indoor spaces and facilities.

Referring to the Malaysian National Security Council, disaster is defined as a catastrophic situation that claimed many lives and caused extensive damage to property and potentially endangers the public peace and security. In Malaysia, there were few natural disaster events that can be said to be among the worst ever in terms of the number of deaths and damages. However, these occurrences were not as severe as overseas. At the end of December 2014, there was a catastrophic flood called as the 'Bah Kuning' was hitting the east coast of Peninsular Malaysia. It resulted in almost 85% of the total Kuala Krai area inundated by flood water. One of the elements in post-disaster recovery is rebuilding shelter for victims. Regardless, it is important to research on residents’ satisfaction as it will affect the well-being directly or indirectly. Thus, a study was carried out to evaluate the satisfaction of residents (victims) on the “New Permanent Houses” (Rumah Kekal Baharu, RKB) that they received from the redevelopment project. A questionnaire survey was carried out to collect and understand respondents’ satisfaction on the redevelopment of their housing area, in specific, the quality of their newly reconstructed houses and the supporting facilities or infrastructure in their area. From the analysis, it was found that majority of the respondents were satisfied with their newly redeveloped houses and the infrastructure. The satisfaction level was associated with the locational and land ownership factors.

Published: November 2018

This paper aims to explore the rich potential of interactive visualisation environment integrating GIS for modelling urban growth and spatio-temporal transformation of Malaysian cities. As a case study example, authors consider a 3-D GIS model of Ampang Jaya, Selangor to investigate the techniques of data acquisition, data reconstruction from physical to digital, urban analysis and visualisation in constructing a digital model ranging from low to high geometric content including 2-D digital maps, digital orthographic and full volumetricparametric modelling. The key aspect of this virtual model is how it would assist in understanding the urban planning and design of Ampang Jaya by translating complex spatial information that are currently used by the authorities for planning activities such as maps, plans and written information into responsive, easily understandable spatial information. It could serve as a new platform to disseminate information about Ampang Jaya, bridge gaps among professionals involved in planning processes, improve communications among decision makers, stakeholders and the public as well as support decision making about thespatial growth of Ampang Jaya. Demonstrations of Ampang Jaya will also provide a clearer picture of the importance of ownership and control of 3-D models by local councils in empowering them in decision making, for example, in improving transparency, and avoiding misuse by project developers (Shiffer 1993; Sunesson et al., 2008). Such environment will improve the subsequent digital models and research in the area of urban design and planning in Malaysia where visual communication is pivotal.

Authors: Zamri Mohd Amirul Hakim , Abdullah Jamalunlaili
Published: November 2018

In Kuala Lumpur, there are a few heritage schools that are more than 100 years old which have experienced significant infill developments since colonial era. This study evaluates the infill building structures and proposes a suitable design approach of infill development in heritage school. It focuses on the infill development theory, reviews on the physical aspect of heritage school buildings as well as related local policies and guidelines. In order to achieve the research purpose and objectives, the study uses the qualitative methodology. The studyfound that there are 2 infill design approaches, which is the complementary design approach and contrast design approach and both can be used as long as compatible and in harmony with the existing heritage building and site. Through site observation survey, it was found that although infill development at St John’s Institutions and Maxwell Secondary Schools adopted the contrast approach, the outcome were different. Infill development at St John’s Institutions was compatible and in harmony, while at Maxwell Secondary School was theopposite. Therefore, this study suggests improvement on the existing infill structures in the heritage school, either through image restoration or transfer of facilities to future development. Other recommendation include the government providing infill development guidelines for heritage site, encouraging private sector to participate in heritage school conservation and development, and controlling the height of new development within 100 meter radius from heritage buildings.

This study has a special interest in urban public transportation institutional framework in the Klang Valley, Malaysia. The notions for the topic were developed from issues regarding institutional framework in delivering urban public transportation. Although the current urban public transport in Klang Valley has improved, there are still issues concerning the institutional framework. To date, there is no single regulator or agency with the express and overriding responsibilities for strategic management of the public transport system in KlangValley. The purpose of this study is therefore to assess the current urban public transportation institutional and governance framework especially towards urban mobility. To achieve this, the study employs the content analysis and case study method, using the purposive sampling approach for expert interviews in gaining the data from participants of related agencies. It examines the importance of public transportation frameworks and present status of current transport development, as well as the roles of urban transportation agencies involved in delivering urban public transport. Results demonstrated that urban public transportation is delivered through multiple agencies with separate roles, not counting the inconsistency of various policies. Hence, the expectation of this study is to suggest practical approaches to improve the current institutional framework of urban public transportation.

Numerous studies acknowledged green open space (GOS) as part of the sustainable component which promotes livability and active community. GOS offers the opportunity for people to socialise through appropriate outdoor setting. Acknowledging countless GOS benefits, hence it appears relevant to plan for a good quality of GOS (QGOS). A QGOS ensures park users enjoy maximum utilisation and benefit of outdoor spaces. Having a good QGOS is one of the government strategies included in the 11th Malaysian Plan 2016-2020, to improve people quality of life. Numerous urban related studies had shown that proximity, use pattern, sociability, accessibility and varieties of activities are the significant factors for successful parks design with the consideration of needs and preferences of park users. Hence, this paper will focus on park use pattern to access the quality of the neighbourhood park (QNP) in Malaysia. The objectives are; i) to identify park use pattern among Malaysian, ii) to determine influential factors of Malaysian park use pattern. A quantitative method of questionnaire survey was conducted to obtain the data. Factor analysis results generated from the 1,500 respondents surveyed at 15 Malaysian neighbourhood parks indicated that nature appreciation loads the highest (Eigenvalue = 2.067, Variance Explained = 29.534%), social and active activities (Eigenvalue = 1.270, Variance Explained = 18.137%), followed by passive activities (Eigenvalue = 0.825, Variance Explained = 11.785%). Together, this finding provides essential guidance for park planners to plan for future QGOS and as part of the support to the 11th Malaysian Plan (2016-2020).

Sustainable development is key to the strategic sustainability within a society. Sustainable neighbourhood development (SND) is a fundamental element of a sustainable community. However, SND on it own will certainly not permit all stakeholders, particularly the end-users, to efficiently address current or projected future issues that positioned beyond the extent of physical development scope. Thus, this research aims to explore whether pre-occupancyassessment criteria addresses the adaptive measures of sustainable dimension pillars (SDP) upon post-occupancy holistically. The research objective is to identify the post-occupancy sustainable criteria gap of SND. To achieve this, the research applied Stakeholders-Inclusion Approach using Post-Occupancy Evaluation Model (POEM) Handbook as measurement tool. This research seeks to measure and identify SDP gap on economic, social and environmental balance and responsive approach towards incremental improvements in SND at community and individual levels. The findings indicated that there are SDP adaptation gaps in post-occupied SND.

Planning permission is prerequisite in development control process as it acts as one of the most significant and effective factors that determine the quality built environment and physical planning. This paper focuses on the temporary planning permission, which is a short-term approval and is only permissible for temporary use of land and buildings. The potential advantages of temporary planning permission have yet to be explored by the planning authorities in Malaysia. This study is aimed at exploring the implementation of the planning permission delivery process in controlling the development of land and building on a temporary basis. Thus, the objectives are intended to examine the process and procedure of temporary planning permission for urban development in relation to Act 172, to ascertain the role and function of the local planning authority, and reviewing the provision of law related to the temporary planning permission as in the Act 172. Comparative analysis between Act 172 (West Malaysia), Planning Act (Cap. 232) (Singapore) and Town and Country Planning Act 1990 (UK) in terms of decision making process has been made to explore the best practices in temporary planning permission. This study is anticipated toenhance the temporary planning permission delivery process and the development control system in Peninsular Malaysia.

The process of urban development today treats buildings as isolated objects, not as part of the larger fabric of streets, squares, parks and viable open space, and without an understanding of human behaviour. What emerges in most environmental settings is unshaped antispace. The essence of this research seeks to establish a better understanding towards the local perception of lost space in the urban core areas of Kuala Lumpur and identify the appropriate tools to improve the usability of the space. The research has been designed with the aim of seeking effective ways of designing a space in the urban core to minimize the undermanaged space. For this reason, the research focuses on the definitions and characteristics of lost space before the process of designing the space. A qualitative analysis is made on selected parameters in the theory of lost space by Trancik (1986); activities, accessibility, connectivity, maintenance and design aspect. Through a qualitative approach, the result indicates that there were various new perceptions of descriptive lost space includes economic and social activity, connectivity, and accessibility as these are an important strategy for maintaining the vitality and robustness of urban space. It is proposed in this paper that more attention should be given to urban areas to continue to give cities’ life and vitality, and the most significant result is to achieve holistic sustainable planning andmanagement of urban space.

This paper seeks to understand patterns of residential preferences of urban Malaysians when seeking to purchase residential properties. Data was gathered through sampling surveys targeting potential house buyers in property fairs in three urban centres in Malaysia, namely Kuala Lumpur, Georgetown and Johor Bahru. Results highlighted significant presence of young purchasers and firsttime buyers; majority seeking to purchase properties priced RM600,000 and below; and taking very long tenure to finance the properties. Double-storeyterrace and condominium, accumulatively garnered higher popular choice, but both fell short of ‘Most Preferred’ category. Factor analysis discovered that overall landed properties fared better than multi-storey buildings as preferred residential typology across the board regardless of socio-economic backgrounds. Family situation and circumstance, referring to marital status, number of family member, and whether they previously owned a property, were found to be the most crucial factors governing their choice on the preferred type of residential properties.
