Cellular Internet of Things (C-IoT) is one of the emerging 5G technologies. 4G LTE being the most promising cellular technology so far and is a suitor for serving C-IoT devices. In future millions of C-IoT devices will be deployed in the coverage of a single 4G LTE base station. However, the existing random access (RACH) mechanism in 4G LTE is not designed to connect millions of devices. Hence, in...
An analysis of MATLAB® integration into mathematical modules at two UK universities is carried out. Both MATLAB integration projects appear to be successful, despite the fact that the two institutions in question are quite different, with one being a well-established research intensive institution and the other a teaching-oriented institution that gained university status in 1992. Despite these differences...
Model-based testing is used for automatically generating test cases based on models of the system under test. The effectiveness of tests depends on the contents of these models. Therefore, we introduce a novel three-step model refinement approach. We represent test models in the form of Markov chains. First, we update state transition probabilities in these models based on usage profile. Second, we...

A number of probabilistic flooding schemes have been recently considered in VANETs to address problems of information dissemination in safety applications. The design approach has so far been simulative, a method which does not guarantee that the derived protocols will work when the simulation settings are violated in practice. In this paper, motivated by the need to design information dissemination...
For any large scale cloud applications coming around large geographic distribution, the large requirements have to be evaluated by the developers. Simulation procedures are very much useful for the researchers during their research process. Their own algorithms can be tested in a cloud environment using any type of simulators. Therefore, the common toolsets have to be used for evaluation and modeling...
Sub-Resolution-Assist-Feature (SRAF) placement is an essential approach of Resolution Enhancement Technology (RET) [1], especially for technology node below 45nm. A lot of studies show SRAF can help to improve semi-dense and isolated patterns resolution and process window. However SRAF effect to dense pattern is rarely focused. The border line of the dense pattern is an isolated line on the outer...
Petri Nets (PN) modeling has been proposed as an alternative to Ladder Logic Diagram (LLD) modeling to program complex programmable logic controllers (PLCs) due to its high level of abstraction and functionalities. Due to design legacy, existing LLD models are converted to PN models. This paper proposes a new algorithm to efficiently convert existing LLD models to their PN models equivalences. The...
This article focuses on the tracking control problem for nonlinear analytical systems. A polynomial state feedback controller is designed to guarantee that the system output tracks those of linear reference model. The parameters of the feedback regulator are derived by solving a linear algebraic problem in the least square sense. The efficiency of the proposed control strategy is illustrated by mass-spring-damper...
Actuators and Manipulators either robotic or mechatronic require controllers which are very accurate and fast. The rotary inverted pendulum has been an under actuated system classified as a potential model in the category of advanced research problems. In this paper, a method is proposed for stabilization of a rotary inverted pendulum using full state feedback controller based modified particle swarm...
Cloud computing is a new, promising technology for future computing platforms and is expected to provide easier access to remote computational resources. Task scheduling is one of the active research area in cloud computing. Task scheduling algorithms play an important role to reduce the turnaround time and to improve the resource utilization. This paper presents a new task scheduling algorithm which...
Reputation-based methods have been widely proposed and practised to foster online trust relationships. Previous works introduced the concept of reputation utility that bridges reputation and trust to reveal the reciprocal transformation mechanism between them. In this paper, an improved model, concerning the popularity of online entities, is constructed. Based on the model, further exploration on...
To keep up with the competition, organizations must be capable to dynamically change business process components at runtime. This problem has been relevant for many years; however, there is no proposed solution, which ensures the dynamicity. This paper presents analysis of related work on dynamic business processes, i.e. the analysis of definitions of dynamic business process and different views on...
This article discusses the influence of customer relationship proneness in hairdresser's context. Data are collected using online survey. A conceptual model about customer relationship proneness, relational benefits, customer commitment and customer loyalty is proposed to explain the influence. Structural equation modelling is used to analyze the data. Empirical results show that customer relationship...
Spatial planning analysis towards conservation of Malay traditional house landscape characteristics is one of the important element in our country. It is because, this element is one of the uniqueness symbol that show the Malay culture in Malaysia and have a big potential for future development. So, to promote this symbol as a Malaysian identity, the government was spent and invested too much money...
The Cox model has been widely used in time-to-outcome predictions, particularly in studies of medical patients, where prediction of the time of death is desired. In addition, the cure model has been proposed to model times of death for discharged patients. However, neither the Cox model nor the cure model allow explicit cure information and prediction of patient cure times (discharge times). In this...
Currently, the electricity demand is exponentially increasing due to the population growth. Therefore, the demand side management (DSM) is becoming unavoidable especially with the increasing use of renewable energy sources. One of the most known tactics of DSM is the use pricing strategies to threaten users to schedule their loads by controlling their own appliances. In this paper, a new model of...
Topic detection always plays an important role in social network analysis. In this paper, we focus on a very simple question that how to choose the terms that can represent a topic better before topic detection. To tackle this problem, we propose an effective model named Topic Model based on Entropy and LDA (TMELDA). The model is built on the user intention, which means different users have different...
The importance of understanding the information technology (IT) adoption process in organizations has been highlighted by many researchers. Information technology adoption at individual or organizational level is a highly researched topic in the IT field. Most literature on IT adoption in organizations is often premised on the assumption that IT investment benefits are always obvious after selecting...
