Published: May 2020

Abstract
Nowadays, road and environmental safety of people during vehicle operation is one of the most important problems. One of the main ways to solve this problem is development and implementation of driverless vehicles, start of operation of which on public roads is expected since 2020-2025. In the process of development, no due attention is paid to addressing the social problem of ensuring passengers’ environmental safety in habitable
compartments of driverless vehicles (DLV) and modern driver-controlled vehicles. This fact may lead to the DLV implementation process restraint and negative consequences in the process of their operation as a result of harmful exposure of people’s life and health to hazardous substances in the air of habitable compartments. The objective of this research is analysis of the solutions for this social problem.

Abstract
With the growth of the average speed of wheeled vehicles, the wear-resistant brake system which would increase their mobility by improving their braking performance and lower the heat loads on the service brake system is gaining interest of the manufacturers. At the same time, a good option for increasing power efficiency of the high-mobility wheeled vehicles is to use an electric machine in the wear-resistant brake system. The electric machine can operate in the generator cycle and provide energy recuperation during braking. Recuperation at braking requires accumulation of high values of electric energy in a storage device (usually a molecular storage device), which brings to the forefront the problem of its efficient capacity selection. The article deals with the selection of the required capacity of an onboard energy storage device providing better power efficiency of the vehicle due to the use of an electric machine in the wear-resistant brake system. The method for the selection of the required capacity of the onboard energy storage device is based on the calculation of the energy spent by the vehicle for maintaining the given speed. The following strategy of the electric machine control was used in the research: the energy accumulated in the storage device after braking will be spent at the next acceleration. Therefore, the power efficiency can be increased only due to such compensation of the high frequency oscillations of the spent/accumulated electric energy in the potential storage device that would prevent reaching its maximum charge level in a typical driving cycle. Based on the results of the research the capacity of the storage device is assessed by the peak-to-peak amplitude of the time history of the accumulated/stored energy when driving along a given route. A method that allows formulation of the specifications for the onboard energy storage device used as an element of the wear-resistant brake system, the method uses statistical data on the road conditions of vehicles operation. The method provides selection of the optimal parameters (required capacity) of the electric energy storage device which would guarantee effective operation of high-mobility wheeled vehicles in typical driving cycles.

Abstract
The article presents the results of mathematical modeling and implementation of algorithms for ensuring the charge balance of an automotive low-voltage battery as part of an intelligent vehicle control system with a hybrid power system. The aim of the research is to evaluate the effectiveness of the proposed complex of mathematical models in calculating the control parameters of the DCDC converter to achieve a positive charge balance of the low-voltage battery. The work evaluates the boundary conditions of the system and adapts the mathematical models and algorithms implemented in the program code of the controller as part of the current model of an intelligent vehicle with a combined power system. The following parameters are evaluated as criteria for the optimality of the proposed models: SOC - state of charge (%), battery charge (A * h), charge and discharge current of the battery (A), voltage on the battery during its charge, in the absence of a charging current and at rest (V). A full-scale experiment was carried out, experimental data and graphs were obtained. Optimal control coefficients for the processes of charge and discharge of the battery, current characteristics, the dynamics of their changes during operation, experimental time-current dependences during the operation of each component of the low-voltage power supply network were studied. The results of the work make it possible to make adjustments to the charge balance management model and contribute to improving the energy balance of the power grid, increasing the efficiency and service life of batteries, forming requirements for power systems and their subsequent implementation.

Published: May 2020

Abstract
Biophilic city is a new term of sustainable cities that connects human to nature by lessening the barrier between them. With a few additional elements from the sustainable city approach, the biophilic city brings human to nature instead of nature to cities or human as adopted by the former concept. Since biophilic city is a new approach not just in Malaysia but worldwide in general, no guideline has been published including the appraisal system on the contractors undertaking biophilic city projects. Many problems occur in the construction industry, and it persists across different projects. Problems related to performance, safety and environment amongst all need to be controlled by both the government agencies and private bodies such as developer and consultant. Even so, the contractor’s appraisal system should also be implemented to ensure the above problems can be reduced or eventually avoided. If regular development facing those problems, a new approach of cities development will face even worst. Hence, this paper, via literature review, aims to investigate the importance of contractors’ performance appraisal system for a biophilic cities development project in Malaysia. This found that: (1) since biophilic city is alient to many, appraisal system for contractor’s performance is important; (2) the current contractor’s appraisal system should be improvised by adding the biophilic elements and; (3) contractors need to mutually understand the appraisal system and the concepts of biophilic cities approach. Since there is a significant need to implement the contractor’s performance appraisal in biophilic city development in Malaysia, this paper suggests that a deeper study in terms of the critical success factors of current contractor’s performance appraisal system should be conducted as to ensure their best performance in reducing or avoiding future problems in biophilic city development in Malaysia.

Abstract
The accident occurred in the construction industry is reportedly the third-highest after manufacturing and agriculture industry. The percentage of accident cases and fatality ratios in the Malaysian construction industry are getting larger and gradually increasing each year. This data indicates that the safety and health performance in the Malaysian construction industry appears to be weak. Henceforth, the Department of Occupational Safety and Health Malaysia (DOSH) through government initiative has introduced and published a guideline on Occupational Safety and Health in Construction Industry (Management) 2017. This guideline aims to decrease 50% of the fatality rates in the construction industry by 2020. Therefore, this paper sought to review the current OSHCIM practice in Malaysia construction industry towards the OSHCIM implementation. This study adopted a quantitative approach in conducting the data collection and the data analysis process. A set of a questionnaire developed, tested and distributed to the construction stakeholders, i.e. client, designer, safety and health officer, contractor, and enforcer. The results discovered that the OSHCIM concept already being “Practice” by the construction stakeholders in Malaysia in terms of the (1) management, and (2) standard operating procedure elements. Thus, this study shows that the construction stakeholders were currently practising the OSHCIM concept but with different procedure and approach. In conclusion, the implementation of OSHCIM in Malaysia construction industry is foreseen to be well accepted as most of the stakeholders are familiar with the concept of design for safety.

Abstract
The high incidents number of injuries and fatality rates in the construction industry are generally due to hazards on site. Early intervention of hazards could lead to safer construction processes. The Safety by Design (SbD) is a process that identifies hazard and assesses risks early in the project design stage, in comparison to during the construction stage. A study in Spain shows that there is still lack of emphasis on the SbD concept in higher education although the concept had been implemented for quite some time. The lack of tertiary education regarding SbD could lead to insufficient knowledge for the effective implementation of SbD by future professionals. As for the Malaysian construction industry, SbD will be soon implemented as the Guidelines on Occupational Safety and Health in Construction Industry (Management) – OSHCIM. Therefore, this paper sought to review the perception of academician regarding OSHCIM implementation. The quantitative strategy is adopted, and a set of questionnaires are distributed among academicians involved in educating architecture, civil engineering, quantity surveying, mechanical and electrical engineering courses in Malaysia’s Institute of Higher Learning. The research indicates that most of the academicians appear to agree that sufficient knowledge and the right attitude is essential for the successful implementation of SbD education in university. It seems that all academicians from different background have higher attitude mean score compared to their knowledge mean score. Even though some of the academicians might not be familiar with the concept, most of the academician was not against it and had a positive attitude towards it.
The benefits of implementation of BIM technologies and tools in significantly construction wastes in the Malaysia construction industry
Authors: Vasudevan Gunalaan 
Published: May 2020

Abstract
Malaysia, as a rapid developing nation with a ballooning construction industry, has fallen victim to a predicament that has affected most similar developing nations, which is the mass outflow of construction wastes. The expeditious advancements made by this sector couple with an all-time high demand of a list of development projects ranging from infrastructure to residential and commercial centres, has led to the production of large amounts of construction wastes which is made exponentially worse by the emplacement of flawed, inconsistent and insufficient practices in dealing with the ever-expanding rates of construction wastes. As a potential solution in mitigating this problem, Malaysia has been looking at the introduction of BIM tools and technologies, as an industry norm, to all construction practices and stages. However, the proper and systematic assimilation of the BIM systems in Malaysia has not proven to be entirely possible yet, particularly in a scale that would be significant enough where it could sufficiently be utilised in the reduction of construction wastes. This limitation, can be attributed to many factors such as the perceptions and acceptance of industry players to learn and adapt to this relatively new software, reluctance in replacing the conventional methods, which the industry players are all too complacent with, of waste managements that have been in-place for decades, coupled with an incomprehension of the myriad of benefits such an implementation could bring about to the local construction industry, as exemplified by many other developing nations that have jumped on the bandwagon of incorporation of BIM into their practices for years now.

Abstract
The post-earthquake housing redevelopment projects success will be much affected when facing with labor, technical staff and experts who are not competent in their field. Moreover, materials scarce supply can cause poor quality of work. At the same time poor community involvement and other important factors that may hinder the project success. Assessment needs also to be carried out in determining the level of damage, location and community conditions so that successful reconstruction can be achieved. This paper provides an overview of the issues and challenges in the implementation of public housing redevelopment projects due to earthquake. The methodologies adopted were mainly focusing on analyzing the information gathered through review of literature and observations made based on personal experience involving in housing redevelopment projects. It was discovered that the most common problem in post-disaster housing redevelopmentis funding. In many instances the government is expected to provide funds earlier. Housing redevelopment project can be an opportunity for corruption which causes loss of project funding, injustice and community rights. Redevelopment projects require top managerial coordination to avoid the ineffectiveness and repetition. Effective policies and strategies are very important to ensure that people’s lives are returned to a better condition and are able to withstand future disasters. Identification of ownership and loss of land documents needed to be identified to prevent the redevelopment process from being hampered and delayed. In order to ensure successful implementation of reconstruction projects issues and challenges that influence its success need to be addressed early.
