The safety performance of an autonomous vehicle based on the longitudinal, lateral and yaw dynamics were investigated. Moreover, steering and braking control under dangerous situations and yaw rate dynamics are of interest in this research. The dangerous situation was modelled as an external disturbance to the vehicle, and as such variations were investigated by the implementation of three controllers: LQR, H infinity – one degree and two-degree controllers. After analysis, H-infinity control approached was found to have the best solution for stability control of yaw vehicle dynamics.

According to some research, building information modelling, or BIM, could be a valuable tool for predicting waste. This paper discusses how BIM could be used for pre-empting waste and reducing the course of the planning and design process of constructing a building. In Malaysia, a questionnaire survey of 340 construction experts was undertaken. Simultaneously, a regression analysis was carried out in order to determine the impact of BIM on the management of construction waste during the planning and design stage. This research could help many stakeholders in the construction industry to recognise various aspects of waste management, beginning with the planning and design stage of a project, which can be represented by designing a model that can be applied to mitigate waste during the construction of a building.

The construction industry generates a significant volume of waste and faces a challenge with poor construction waste minimisation in order to prevent adverse environmental and dumping impacts worldwide. In developing countries, regional waste management systems have increased problems. Environmental pollution (air, water, and soil) and human health issues are caused by waste produced in a country as a result of different cultural, social, and religious activities. Prior studies were reviewed to choose dimensions and items for the data gathering instrument. A pilot test was conducted to identify potential questionnaire adjustments, and hypotheses were tested using structural equation modelling (SEM). A total of 220 Malaysian construction professionals answered the survey, which yielded the results. Fiv...

However, despite the increasing trend of Nigeria economic growth, poverty rate is on the rise. There are many programmes targeted to improve the well-being of the poor which yielded unfruitful results due to their poor implementation. However, Small and Medium Enterprise (SMEs) development have been recognised as essential instrument for poverty reduction. Hence, the aim of this study is to investigate the relationship between SMEs development and multidimensional poverty index (MPI) in Niger State of Nigeria. The quantitative research methods were adopted. In addition, cluster sampling was used to divide the population into two clusters (poverty rate < 80% and ≥ 80%), and convenience sampling techniques was adopted for the selection of 432 SMEs owners. Self-administrated questionnaire was employed in data collection. The first objective of the study was to construct the multidimensional poverty index of hous...

The paper aimed to explain the effect of time overrun (TO) and inflation rate on project completion cost (PCO). Variations in costs and durations of projects were calculated for 250 government and private building projects executed between 2005 and 2015, while inflation rates for the last quarter of these years were used. A multiple regression analysis of cost overrun as the endogenous variable, with time overrun and inflation rates as the exogenous variable was conducted for private and government funded projects. The result revealed that the cost overrun can be predicted by the equations; predicted private cost overrun = -669673.60 + 50182.35 (time overrun) + 106690.20 (inflation rate), and predicted government cost overrun = -9805996 – 148721.90 (time overrun) + 1266038 (inflation rate) respectively for private and government funded projects...

Out of 302 reported and analyzed cases to the Department of Safety and Health (DOSH) from 2010 to 2019, about 0.66% are exposure to hazardous chemicals. This paper developed an AHP model for the factors and subfactors of chemical exposure and determined their relative weights and priorities. Worker's unsafe actions have a maximum weight of about 80.98% for the significant factors based on the proposed model, followed by unsafe site conditions of 10.89% and management factors of 8.13%. Financial constraint carries the most weight with 20.22% for management factors, lack of or improper on-site storage for hazardous chemicals, incorrect labelled or unlabeled signs indicating hazardous chemicals, incorrect labelled or unlabeled containers carrying hazardous chemicals and lack of or improper on-site disposal of used hazardous chemicals with 16.13% each carry the most weight for unsafe site conditions. Rushing to complete the job and unauthorized access to the hazardous chemicals carry the most weight, with 17.24 % each. This study can help safety practitioners understand the factors and sub-factors responsible for chemical exposure and how they can decrease fatal accidents on-site.

Therefore, there is need to search for biopesticides that can be used to control the pest rather than using synthetic chemicals. In this work different concentrations of Agave sisilana n-hexane extract were prepared using twofold dilution at 100, 50, 25, 12.5, 6.25, 3.125 and 1.5625 mg/ml and were used to treat 40 selected beans in different kilner jars. The treated beans were infested with ten (10) identified female and male C. mauculatus each. The result shows that the insect was more killed by the extract at concentration greater than 50 mg/ml. The plant extract was effective against the oviposition and survival of larvae and pupae when compared with the untreated control. In conclusion, the extract of has great potential for use as a plant-based biopesticide for controlling C. maculatus.

This is because the success or otherwise of construction projects is largely dependent on price variations. Using a multi-method approach, this paper assesses the influence of monetary variables on prices of construction materials. An analysis of the F-statistics shows a significant relationship between variables (0.05 significant level and R2 of 0.8) of the construction materials under review. Furthermore, the F-values show that the predictive value align with observed values at 95% confidence level for some of the materials. Based on the forgoing, the study recommends the establishment of monetary frameworks to guard against sudden changes in fiscal policy. The outcome of the study would be useful to the government in regulating the macro economy through the use of macroeconomic variables.

However, it has been shown that in spite of huge amounts earmarked for infrastructural projects, the desired outcome/benefits are not attained in many cases. This has been attributed to poor adherence to project management principles in the conception, design, and execution of these projects. This paper highlights poor project conception and definition, poor budget and stakeholder management, as well as inadequate monitoring and evaluation as major causes of these failures. This can be minimized through the integration of good project management principles in the planning, design and execution of projects, supported by a robust monitoring and evaluation procedure.
