Emotional Challenges across the Welfare provided among the Stranded University Students during Covid-19 Pandemic

The Movement Control Order (MCO) for Covid-19 safety measure caused worry and anxiety among university students, especially those stranded in their university hostels or rental accommodation. Universities’ staffs helped their basic living and study needs. This study aims to determine the emotional challenges among these students and examine the association between their emotional score across the university’s welfare. Based on a survey of 284 respondents, the findings show that there is a significant difference between their emotions and stranded locations. Residential facilities, information updates, and food provided are substantial to their emotional scores.

Analysis and optimum machining parameters on surface roughness and material removal rate for titanium alloy in milling machining with MQL

Proper cutting parameters are needed to produce lower surface roughness of titanium alloy machined material. The high temperature in the cutting zone is always happened due to high friction between the tool and the workpiece and will cause dimensional error and poor surface roughness. Therefore, the main objectives of this research were to investigate and compare the surface roughness and material removal rate (MRR) of Ti-6AL-4 V alloy under the dry and minimum quantity lubrication (MQL) technique. The effect of cutting parameters towards surface roughness was investigated and the optimum cutting parameters was studied to obtain lower surface roughness and higher MRR. From ANOVA, spindle speed has been identified as the most significant parameter that affects the surface roughness and MRR. In t his paper, the optimum cutting parameters that give the low surface roughness and high MRR was 1500 rpm (spindle speed), 0.4 mm/tooth (feed per tooth), and 0.4 mm (depth of cut). From this study, it can be concluded that in this milling of Ti-6Al-4 V alloy, higher spindle speed, feed per tooth, and depth of cut are preferable to achieve the better surface quality of Ti-6Al-4 V alloy

Design and analysis of circular shaped patch antenna with slot for UHF RFID reader

This paper presents an analysis of microstrip circular shaped antenna with slot for ultra-high frequency (UHF) portable radio frequency identification (RFID) reader applications. The fabricated antenna is designed to work with UHF RFID system in Malaysia with frequency allocated from 919 to 923 MHz. The antenna design was made with circular patch and rectangular slot that has the dimension of 122 mm × 122 mm. Moreover, the FR-4 material used in this project has thickness of 1.6 mm with dielectric constant of 4.7 and loss tangent of 0.019. Thus, it is easily connected to the portable RFID reader module together with the antenna characteristics of easy fabrication, low profile and simple structure. From the results, the antenna has the reflection coefficient (S11) less than −10 dB along the bandwidth of 3.6% (903–936 MHz) for operating frequency at 921 MHz

Badminton agility training device

Badminton is one of the most popular sports in Malaysia. This sport requires the athlete to be agile, running around the court to return the shuttlecock. One of the most important training in badminton is the footwork training. This training is conducted on the court without using any shuttlecock. In this drill, the coach stands in front of the players and shows the location where the player needs to go. The players will go to the instructed location, perform an action of a badminton shot, and return to the centre point. This drill is done for a few minutes. This project aims to replace the need of the coach to stand in front by creating an intelligent electronic training device

Internal Motivation as a Mediating Factor in Determining the Competitiveness of Micro Entrepreneurs

ABSTRACT Entrepreneurial motivation is a critical element in enhancing the competitiveness of micro entrepreneurs. The Malaysian government has taken several initiatives in providing motivational training through several federal and state agencies such as Gagasan Badan Ekonomi Melayu (GABEM), Yayasan Pembangunan Usahawan (YPU), Majlis Amanah Rakyat (MARA) and Yayasan Pembangunan Keluarga (YPK) Terengganu. The issue remains whether the micro entrepreneurs are able to sustain their motivation in improving their business competitiveness that will help them penetrate new and bigger markets. In light of this issue, the authors postulate three entrepreneurial success factors and internal motivation as the mediating variable in determining the competitive level of the micro entrepreneurs. A total of 520 micro-entrepreneurs were selected from seven districts in Terengganu, Malaysia. The three steps regression analysis revealed that internal motivation partially mediates all three entrepreneurial success factors, effective management, personal quality and family support. These findings revealed that the combination of internal motivation with other entrepreneurial success factor would be critical in creating sustainable competitive advantage among micro entrepreneurs. The authorities responsible for the development of the entrepreneurs would therefore be wise to design better motivation programs that will sustain their competitiveness in the long run

Piecewise Trajectory Replanner for Highway Collision Avoidance Systems with Safe-Distance Based Threat Assessment Strategy and Nonlinear Model Predictive Control

This paper proposes an emergency Trajectory Replanner (TR) for collision avoidance (CA) which works based on a Safe-Distance Based Threat Assessment Strategy (SDTA). The contribution of this work is the design of a piecewise-kinematic based TR, where it replans the path by avoiding the invisible rectangular region created by SDTA. The TR performance is measured by assessing its ability to yield a maneuverable path for lane change and lane keeping navigations of the host vehicle. The reliability of the TR is evaluated in multi-scenario computational simulations. In addition, the TR is expected to provide a reliable replanned path during the increased nonlinearity of high-speed collisions. For this reason, Nonlinear Model Predictive Control (NMPC) is adopted into the design to track the replanned trajectory via an active front steering and braking actuations. For path tracking strategy, comparisons with benchmark controllers are done to analyze NMPC’s reliability as multi-actuators nonlinear controller of the architecture to the CA performance in high-speed scenario. To reduce the complexity of the NMPC formulation, Move Blocking strategy is incorporated into the control design. Results show that the CA system performed well in emergency situations, where the vehicle successfully replanned the obstacle avoidance trajectory, produced dependable lane change and lane keeping navigations, and at the same time no side-collision with the obstacle’s edges occurred. Moreover, the multi-actuators and nonlinear features of NMPC as the PT strategy gave a better tracking performance in high-speed CA scenario. Assimilation of Move Blocking strategy into NMPC formulation lessened the computational burden of NMPC. The system is proven to provide reliable replanned trajectories and preventing multi-scenario collision risks while maintaining the safe distance and time constraints

Acclimatization of Eurycoma longifolia (Tongkat Ali) Plantlets to Ex Vitro conditions

Eurycoma longifolia is one of the famous herbal plants with great medicinal benefits. The plant which also known as Tongkat Ali is well-known for treating erectile dysfunction and as energy booster. Tongkat Ali plantlets were produced using in vitro propagation technique to cater the demand for planting material. The development of successful acclimatization technique is prerequisite for in vitro propagation method. Acclimatization is a step to prepare the plantlets to survive and grow in different environment compare to laboratory. In this study, an attempt was made to identify the best potting media to acclimatize Tongkat Ali using glass chamber. Rooted plantlets about 2-4 cm height were used and subsequently transferred to different potting media for acclimatization i.e jiffy 7, sand, baked soil, mixture of cocoa peat and sand, sand and top soil and lastly cocoa peat and baked soil. Plantlets grown in jiffy 7 showed 100% survival followed by the mixture of cocoa peat and baked soil with 94.45% of survival. The acclimatized plantlets were transplanted into polybag and maintained in the shadehouse condition
