Demanding of harmonious society is a challenging task in every country especially for multi-ethnicity society. Despite sharing the same homeland, they has their own heritage that reflect their ethnics. Each of the ethnic are defending their respective right. Ergo, the similarities of these diversity, particularly culture and identity should be as a nation forte to unite the society. Overall, 18 criteria was identified which are consist of 11 for national culture and 7 for national identity. Thus, the aims of this paper is a comparative analysis on weighting allocation in determining the importance of these criteria that contribute towards Malaysian harmonious living. In order to identify relevant important criteria, Multi-Criteria Decision Making (MCDM) approach is utilized to allocate the weight for each identified criteria. The findings reveal the degree of importance of each criteria under culture and identity that could be used as a guideline for national policy maker and relevant government authorities to planning the activities specifically when it is involving the community as a whole.Demanding of harmonious society is a challenging task in every country especially for multi-ethnicity society.

For any organisation that offers certain services, waiting time is very important as it indicates the level of service performance. University Service Centre (USC) is a one-stop centre that provides most of the services for students’ affair. It is estimated that around 667 students pay a visit to USC every day for the services. Although there are twenty seven counters, only three of them are very busy. The issue arises whether all the counters are fully utilized by the management. The purpose of this study is to evaluate the performance of USC in giving services to the students. The simulation model is developed to represent the real operation system of the USC. The data is obtained from the USC database for the period of 4 days of operation. The results show that the maximum waiting time for information counter, counter 24 and counter 25 in USC are 16.37 minutes, 160.95 minutes and 42.41 minutes, respectively. Two scenarios have been created for what-if analysis in finding ways to improve the service performance. The findings can help the management of USC to plan and manage resources efficiently while providing the best services.For any organisation that offers certain services, waiting time is very important as it indicates the level of service performance.

We are interested to investigate whether the presence of the third nearest-neighbour would give any significant effect on the generation of the phase diagrams. For this purpose, we analyze the phase diagrams of the Potts model with prolonged competing binary interactions J2 and J3 on the Cayley tree up to the third nearest-neighbour generations. We derive the recurrence system of equations and investigate the phase diagrams for several ranges of the competing parameters. Then, we conduct a numerical analysis by carrying out an iteration scheme on the phase diagrams. For some non-zero parameter J3, we found the additional phases of period 5, 6, 9, and 11, along with the ferromagnetic, antiphase, paramagnetic, antiferromagnetic and modulated phase.We are interested to investigate whether the presence of the third nearest-neighbour would give any significant effect on the generation of the phase diagrams.

One of most important techniques that plays a key role in elevating a mobile robot’s independence is its ability to construct a map from an unknown surrounding in an unknown initial position, and with the use of onboard sensors, localize itself in this map. This technique is called simultaneous localization and mapping or SLAM. Over the last 30 years, numerous new and interesting inquiries have been raised, with the improvement of new techniques, new computational instruments, and new sensors. However, the big challenges facing mobile robots in the next decade, as in the autonomous urban vehicles, require extended representations that exceed traditional mapping found in classical SLAM systems, i.e. the so-called semantic representation. The main goal of a SLAM system with semantic concepts is to expand mobile robots’ services and strengthen human-robot interaction. Related works reviewed show that the visual-based SLAM or VSLAM has received a great deal of interest in the last decade. This is due to the visual sensors’ capability to provide information of the scene whereas they are low-priced, smaller and lighter than other sensors. Unlike the metric representation, semantic mapping is still immature, and it comes up short on durable formulation. This paper aims to systematically review recent researches related to the semantic VSLAM, including its types, approaches, and challenges. The paper also deals with the classical SLAM system by giving an overview of necessary information before getting into detail. This review also provides new researches in the SLAM domain facilities to further understand the anatomy of modern VSLAM generation, discover recent algorithms, and apprehend some open challenges.

Duopoly is a market dominated by two firms, where the action of one firm will affect the other firm and also the market price of the product. In a Cournot duopoly, firms make their moves at the same time while in Stackelberg duopoly, one firm becomes the leader and so make the first move, followed by the other firm. In this paper, a duopoly market with isoelastic demand function and linear production cost is considered. The profit gained by each firm when both are competing in a Cournot duopoly and Stackelberg duopoly model were derived and compared. Results showed that regardless of whether the firms are moving simultaneously or sequentially, the firm with the lower production cost would gain a greater profit than the firm with the higher production cost. Also, profit wise, a firm with greater production cost than the other firm is better off making the first move instead of moving simultaneously with the other firm or following the other firm. On the other hand, a firm with lower production than the other firm is better off in becoming a follower rather than making the first move or moving simultaneously with the other firm.Duopoly is a market dominated by two firms, where the action of one firm will affect the other firm and also the market price of the product.

Air pollution is a crucial subject that needs responsiveness from all relevant authorities as it is one of the major factors that disturbing public health, agricultural industries, forest species and environments. Thus, it is important to determine the most significance contaminants to monitor the air quality. In this study, the daily data of contaminants suspended in the air which are particulate matter (PM), and various gases such as ozone (O3), nitrogen oxides (NO2), sulphur dioxide (SO2), and carbon monoxide (CO) are used. It is covering a four year time period from 2011 until 2014 that vetained from the Malaysian Department of Environment (DOE). Multivariate statistical analysis such as a radar plot, correlation analysis and principal component analysis is used to determine the most significant contaminants for the air-pollutant. From the study, it can be concluded that that Nitrogen Oxides (52%) is the most influential contaminant of air pollutants followed by Particulate Matter (43.9%) and Carbon Monoxide (43.3%).

In this research, the Benjamin-Bona-Mahony (BBM) equation is solved numerically using cubic B-spline (CBS) collocation method. The BBM equation is transformed into a system of two equations and Besse’s formula is applied to the nonlinear term. Then, Forward Difference Approximation is used to discretize the time derivative while the CBS function is used to discretize the space dimension. Two numerical examples are discussed and compared with the exact solutions.In this research, the Benjamin-Bona-Mahony (BBM) equation is solved numerically using cubic B-spline (CBS) collocation method.

Then, Forward Difference Approximation is used to discretize the time derivative while the CBS function is used to discretize the space dimension. Two numerical examples are discussed and compared with the exact solutions.
