This paper studies stability of interconnections of hybrid dynamical systems, in the general scenario that the continuous or discrete dynamics of subsystems may have destabilizing effects. We analyze two existing methods of constructing Lyapunov functions for the interconnection based on candidate ISS Lyapunov functions for subsystems, small-gain conditions, and auxiliary timers modeling restrictions...
The purpose of this study is to investigate the best practices in the transdisciplinary field of knowledge management system implementation and measurement of IT Complain in a telecommunication company (PT Telkomsel). This paper examines three variables of Knowledge Management (People, Process and Technology) and IT Complain Variable. This research used two methods such as a qualitative and quantitative...
This study aimed to support the effectiveness and efficiency of employee performance in the Provincial Education Office (Dinas Pendidikan) regarding teacher placements in elementary school, middle school, and high school. Three provinces are chosen as samples: Bali, Yogyakarta, and DKI Jakarta. The employee performance assessment was conducted using criteria and weight calculation regarding teacher's...
The earlier result of his research showed that most Taiwanese SME designers were frustrated in innovations since it takes hard evidences to persuade their managements, but they are in lack of resources. Thus, this research proposed the SSFD model with ready templates to help them. This paper focused on the third stage of the SSFD Model, i.e. "The Stage of Strategy Formulation". It will help...
This paper presents a methodology combining Failure Mode and Effects Analysis (FMEA) and Value Engineering (VE), assisted by a set of hierarchical Functional Analysis Diagram (FAD) models, and its pilot introduction in a UK-based manufacturing Small Medium Enterprise (SME). The proposed methodology suggests the parallel execution of both processes, using a combination of FAD models and the FMEA tabular...
The visual comfort of human being has been gradually considered in high performance building since the higher living quality and lower energy use requirements. Good lighting layout is more and more important, especially in classroom for the students' vision. The number and location of light sources are traditionally determined by the experimented engineer or technician. However, un-precise results...
In view of recent economic or shared resources shared ideas advocated the development of network technology and applications, this trend has also led to the digital content industry-related design industries and the development of cultural and creative industries, this study hope that through analysis of the designer in while authoring modeling required design resources to design the Creative Design...
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...
Plant growth models able to simulate phenotypic plasticity are increasingly required because (i) they should enable better predictions of the observed variations in crop morphology and production, and (ii) their parameters are expected to have a more robust genetic basis compared to conventional crop models, with possible implications for selection of quantitative traits such as interplant competition...
Urban traffic network is a typical example of a complex system called hybrid dynamic system (SDH). Although hybrid automata (HA) is a popular formalism in modeling, analysis and controlling SDH, the HA model of large scale urban traffic network gets substantially complicated for analysis and control due to large dimensionality of such systems. To overcome this problem, a new hierarchical control structure...
In this paper we present a HAZOP Assistant based on D-higraphs and dedicated to a functional modeling technique that gathers functional and structural information of the process under study. The Assistant and the methodology are presented and applied to a High Density Polyethylene reactor part of the CP2K plant situated in the petrochemical platform of Skikda.
Classroom activities that are based in the real-world are known to be impactful. Similarly, activities that relate to social good have been found to be engaging and meaningful for students especially to those from underrepresented groups. Many times, these activities tend to be design based projects, and while meaningful, activities of that nature may not be suitable for every class. In this innovative...
This paper proposes a simulation platform developed to study and identify critical cases in a Smart Grid. A distribution network with different Distributed Energy Resources (DER) components, connected along the feeders, is analyzed, having the objective to identify limitations of existing simulation and planning tools, with a particular objective on the challenges faced by the introduction of Smart...
This paper presents the research field analysis method using the Linked Data of I-Scover [1]. I-Scover is the article retrieval system of the Institute of Electronics, Information and Communication Engineers (IEICE). This system manages the article metadata by Linked Data format. The research field analysis of the articles is important, and the effective article classification is desired for faceted...
The recent attentions on video analysis have led to the extensive enhancement of computer vision technologies. However, it is still necessary to closely monitor the results of video analysis by human operators. This paper introduces a trajectory-based scene retrieval system that can help human operators look closely at desired scenes based on a trajectory query. The system includes the index and mapper...
Recent examples have shown that sophisticated cyber attackers are capable of infiltrating the cyber defenses of major organizations and spreading stealthily through a network, potentially doing significant damage before exploited vulnerabilities can be identified or patches developed. Autonomous systems are particularly vulnerable because they are further removed from human intervention. One emerging...
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...
The so-called “ilities” of a system—such as safety, interoperability, and efficiency—should be designed into systems from their very conception, which can be achieved by integrating more powerful analysis techniques into the general systems engineering process. The primary barrier to achieving this objective is the lack of effectiveness of the existing analytical tools during early concept development...
The primary goal of this paper is to investigate what could have made successful Google's OpenSpot, a crowdsensing based parking assistance application cancelled in 2012. For this analysis we have developed UPark, a simulation environment capable of simulating large numbers of vehicles, which look for optimal parking spots in busy urban environments and whose drivers might inform others when they...
