Model order reduction plays an important role in the analysis of the fractional order systems. Fractional systems being more complex in nature are not easily processable. Hence for mathematical understanding of such systems it is fundamentally important to derive their proper integer order approximations. These integer order approximations are obtained using a well known technique, the Oustaloup method...
VANETs can benefit by using an infrastructure-less model such as Floating Content (FC) in absence of infrastructures or as support to these latter. This work presents FC performances in vehicular context by using Random Waypoint mobility model.
This study was conducted to identify the relationship among some intrapersonal factors such as professional competency, interdisplinary ability, social skills capability, and team cohesion. The validated questionnaire was delivered to 296 students in the design programs of universities as research samples. Consequently, the SPSS 18.0 and AMOS statistic software were used to analyze the collected data...
In this paper, we review and prove certain properties regarding t-way coverage when covering arrays are merged together to form larger arrays. Moreover, we build upon these theoretical observations to formulate a procedure on how, from the input space model of a composed SUT and t-way test suites for its components, to create a larger and unified t-way test suite. The proposed modelling methodologies...
We consider in this paper a discrete-time deterministic m-ary diffusion model over a strongly connected directed graph. The update rule is easy to state: let the vertices of the graph represent the agents and the edges represent the information flow; at every time step, each vertex updates its value to the maximum value held by its incoming neighbors at the last time step. The resulting system, defined...
In this study, a game integrated historical events were designed for improving and promoting students' motivation and understanding for history education. For this reason, the epistemological beliefs were incorporated in the model to explore students' digital games preference by applying technology acceptance model (TAM). A total of 112 fifth grade students in an elementary school were participated...
This paper presents a preliminary analysis of an active Bayesian observer that communicates with humans to correct the overconfidence effects due to their confirmatory biases. Two types of confirmatory biases, called Z- and E-types, are introduced and formalized using a model of noisy channels between signals and perceptions. Persons suffering from Z-type confirmatory bias receive a signal and perceive...
Response time plays an important factor in determining the Service Level Agreement (SLA). For the reason that actual measurement costs a large amount of resource, theoretical/numerical analysis based on Stochastic Process Algebra (SPA) is a good choice to obtain the response time of concurrent systems. Among all SPAs, Performance Evaluation Process Algebra (PEPA) is the most popular one due to its...
A new concept of composition is proposed in the framework of the Graph Model for Conflict Resolution. Two graph models whose sets of decision makers are identical are composed into one graph model. The composition is interpreted as a situation in which the same decision makers are involved in two independent conflicts at the same time. Relationships between stabilities of states in a composed graph...
In polytopic model-based controller synthesis, the vertices of the model determine the achievable performance characteristics. This paper introduces a new concept, that allows for the sophisticated construction of non-simplex enclosing polytopes. The non-simplex structures in general, have much better descriptor properties than the simplex one that leads to less conservative synthesis. The paper demonstrates...
This paper proposes a new method to analyze driver behavior. Analysis of the behavior is done through the observation of the time-evolution of parameters of simple driver models. The behavior analysis is decomposed in two steps. First the driver model have to be selected or designed to represent the average behavior of a large sample of drivers. Then personal driver's behavior evolution can be analyzed...
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...
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...
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...
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...
Issues related to power quality of electrical service are becoming more and more concerning, not only because of the impact that they have both for the industrial production system and for the service industry in a globalized and competitive world, but also because of the regulatory authorities' penalty systems that are pushing Distribution System Operators (DSO) to ensure better service standards...
In this study, we conduct agent-based simulation experiments of network formation focusing on a mathematical model proposed by Berninghaus et al. (2007) such that a periphery sponsored star network is the strict Nash equilibrium. Hayashida et al. (2011) conducted the simulation experiment using NN(Neural Network) and GA(Genetic Algorithm) model to analyze behavior of human subject in the experiment...
This article focuses on the study of detecting key individuals in terrorist network, combining the theories and algorithms of Social Network Analysis (SNA), Multi-meta Network Analysis and Fuzzy Analytical Network Process (FANP). Firstly an index system is built and then within this system the scores of terrorists are calculated, referencing the measures (total degree, betweenness, closeness, etc)...
In this work modeling and control strategy is presented for the simultaneous control of oxygen and carbon dioxide blood gas partial pressures to be used during cardiopulmonary bypass surgery with heartlung machine support. As the exchange of blood gases in the artificial extracorporeal lung is a highly nonlinear process comprising varying time delays, uncertainties, and time-varying parameters, it...
