Orchestrator has found applications in integration of software services. An Orchestrator is like a coordinator. It provides controlled computation at parallel and sequential computational nodes. Many computational problems need the solutions of simultaneous equations which have large number of coefficients. This paper presents a novel application of an Orchestrator Framework to find faster solution...
In medical field the disease diagnosis is often made based on the knowledge and experience of the medical practitioner. Due to this there are chances of errors, unwanted biases and also takes longer time in accurate diagnosis of disease. In case of heart disease, its diagnosis is most difficult task. It depends on the careful analysis of different clinical and pathological data of the patient by medical...
The system introduced here is an experimental study which helps in controlling the characteristics and ON/OFF states of a control valve. A graphical user Interface has been developed using supervisory control and data acquisition (SCADA) and the programming of the control system has been done using programmable logic control (PLC). A descriptive study has been incorporated in this paper to formulize...
The trends and necessity of running business organizations from multi-locations and multi-nations caused huge demand for distributed databases. The performance of any distributed database is highly depends on th e fragmentation of global relations and allocation of those fragments at different sites of the network. The data or fragment allocation ma y be performed either by static or dynamic ways...
In the presented paper, we consider initial values entering into an element ‘zero’ with period one for logistic maps over integers. First, we derive the logistic map over integers. Second, we describe that only two elements, namely zero and the maximum value in domain of the logistic map, enter into the loop with zero, respectively, for control parameters less than 4. Last, we show that three elements,...
Online social networks such as Sina Weibo micro-blogging website allow user to annotate himself (or herself) using tags, which describe the characteristics of the user. Many researches have been done on photos, films, commodities but rare researches on users. In this paper, we try to recommend tags for users who can communicate directly with other users. Our method is based on interactive relations...
This paper aims at the implementation of 16 bit floating point multiplier using Residue Number system. Residue Number System (RNS), which is a non-weighted number system gains popularity in the implementation of fast and parallel computing applications. It has inherent properties such as modularity, parallelism and carry free computation, which speeds up the arithmetic computations. Floating Point...
We consider the dynamic search of a target located in one of K cells. At each time, one cell is searched, and the search result is subject to false alarms. The objective is a policy that governs the sequential selection of the cells to minimize the error probability of detecting the whereabouts of the target within a fixed time horizon. We show that the optimal search policy is myopic in nature with...
This paper presents an unsigned truncated recursive multiplier architecture based on the variable correction method. The proposed design can be partitioned to perform as one N-bit fixed width multiplier or as two N/2-bit full precision multipliers. Design targets single level recursive multiplier architecture. Exhaustive analysis was carried out to calculate the maximum error bound in case of truncated...
There is a growing interest to understand the fundamental principles of how epidemic, ideas or information spread over large networks (e.g., the Internet or online social networks). Conventional approach is to use SIS models (or its derivatives). However, these models usually are over-simplified and may not be applicable in realistic situations. In this paper, we propose a generalization of the SIS...
The linearization of the differential equations is always the important work in the study of partial differential equations. In this paper, a necessary and sufficient condition is established for the existence of a 1-1 transformation of a system of nonlinear differential equations to a system of linear equations is shown with some examples including Burgers' equation and the Liouville equation.
This paper is concerned with the simultaneous actuator and sensor faults reconstruction problem using sliding mode observer for polytopic Linear Parameter Varying (LPV) systems. Sufficient conditions in terms of Linear Matrix Inequality (LMI) are derived to guarantee the stability of such observer. A simple filter is introduced to transform the sensor fault into a pseudo-actuator fault scenario and...
This paper deal with the use of fuzzy sets whose shape evolves as the error to construct a robust PDC fuzzy controller for nonlinear system in continuous time described by the T-S fuzzy model. This controller is based on time-Varying Fuzzy Sets (VFS) characterized by the displacement of the support points to both right and left side of the universe of discourse, and they are directed by a well-defined...
In this paper ART2 classifier is used to extract clusters of databases taken from complex processes with different behaviors. The used classifier is an unsupervised one and the obtained clusters characterize local models of a considered system. These local models represent linear behaviors of the process. This result is the consequence of the characteristic of the F1 layer of the ART2 neural network...
Hybrid Bond Graph (HBG) is a bond graph-based modeling approach which provides an effective tool not only for dynamic modeling but also for fault detection and isolation (FDI) of switching systems. Efficient algorithms exist for fault detection and isolation based on functional redundancy. In a qualitative approach, this redundancy can be captured by a temporal causal graph (TCG), a directed graph...
This work was done in Tunisian Chemical Group (TCG) factory Skhira producing phosphoric acid. It involves studying the filtration of slurry of phosphoric acid manufacture in second stage. This study will focus on the physical modeling of filtration phase and the setpoint is optimization under constraints which takes into account the different functional requirements of the system. The optimized parameters...
In this paper we present a method for prediction and trajectory tracking of a set of vehicles operating in a port. The objective is to enable the prediction of risk situations in order to avoid collisions. The system is designed for high traffic areas located in ports or civil engineering projects, environments in which traffic occurs without structured lanes of movement. While many studies have been...
This paper presents a nonlinear control of a synchronous permanent magnet machine based on second order sliding mode control using super twisting algorithm. This algorithm allows to reduce the chattering phenomenon. Simulation results are presented to show the effectiveness of the proposed control method.
The work reported in this paper deal with of Finite Impulse Response FIR digital filter design by using window method. The window method is easiest to design FIR, but lacks flexibility especially when the passband and stopband ripples are different. The digital filter is used to filter discrete time signals with the ability to modify the frequency response of the filter at any time and it used in...
