In recent years, we have witnessed a growing interest in Business Continuity (BC) solutions to reach maximum availability of computing resources, where the main function is to provide a high available and smooth fail over and fail back processes. Our growing needs to provide world-class and high available computing resources to serve Saudi Aramco's Oil and Gas Upstream Operations has given us the...
This research presents a logical approach for implementing dynamic business rules based on a context-aware integrated BPM-SOA framework [18]. Specifically, a system is developed to demonstrate how Internet-based commercial lending operations with intelligent decision making can deliver faster speed, improved consistency and reliability throughout the entire lending process with scalability. With Internet-based...
The firm's capability to develop product innovation and successfully launch new products has been regarded as crucial determinant in sustaining a firm's competitive advantage. Firms have been faced with a complicated problem in selecting innovation development project. From review of the related studies we found two groups of capability, firm's innovative capability and firm's new product development...
This paper addresses the problem of structural control for mitigating seismic effects in the presence of structural parameter uncertainties. A linear single degree-of-freedom (DOF) structure is considered. It is supposed that mass, damping and stiffness coefficients of the structure contain uncertainty. Two different methods based on sliding mode control (SMC) are proposed. The first method uses upper...
In this paper, one helicopter model with two degrees of freedom (2-DOF) is controlled by fuzzy sliding mode control with boundary layer (FSMC-BL) while exposed to disturbance. The model is a nonlinear and multi-input multi-output (MIMO) system that requires a MIMO, robust, stable, and nonlinear control to reject the disturbance. These requirements have been satisfied by SMC. In this paper, boundary...
This paper presents 3D simulation work for ion-drag micro pump. The commercial simulation software Comsol Multiphysics 4.2 was used to model and simulate ion-drag micro pump for three different configurations of collector electrode. The purpose of the simulation was to investigate the ways to improve the performance of the micro pump and analyze the effect of the electric field, fluid velocity and...
In the context of water networks, in order to supply water to consumers without any disruption in service, the state of the system has to be monitored. One way to achieve this is by using simulators algorithms that provide means of combining the water consumptions called also pseudo-measurements by relating them to the mathematical model of the system. Therefore a comprehensive description of the...
Steam temperature of a steam distillation process possessed variable process gain and a significant dead-time when operating from 27oC to its saturation point. Model accuracy is an important factor when tuning a PID for temperature regulation using model-based method such as open-loop Ziegler-Nichols. This study will evaluate the adequacy of two models; each estimated at different operating range...
This paper is a review of principles and aims of partnering to improve quality and efficiency within the manufacturing industry. Partnering is used to carry out this research so that we can ascertain the features and issues that contribute to trust within the partnering arrangements. There are many other procurement routes available in manufacturing industries which are having different qualities...
The DC motor speed control is commonly used in several robotic applications. Thus the controller design for the DC motor speed control is a compulsory to optimize the performance of the motor towards the system design specification. In this paper the DC motor mathematical model is obtained then Three linear controllers, which are PID, LQR, and Q-parameterization controllers are designed for controlling...
In this paper we introduce a new programming language for Micro controller using bond graph. Bond graph is a system for modeling in Mechatronic systems. The advantage of using bond graph for Micro controller programming is the use of a common language for hybrid mechanical and electrical systems. For a better understanding we use Statement method which is a circuit definition language. We have used...
Fuzzy direct controllers are being used widely in industry these days. One of the benefits of fuzzy controllers is their ability to control unidentified processes which lets a model free controlling scheme; but on the other hand, an efficient fuzzy direct controller design, strictly depends on human expert and knowledge of a certain process. This will limit the ability of noncontrol specialists to...
The philosophy envisages to enhance the overall power quality of a DC drive system through a mechanism that attempts to phase correct the input current. It orients to improve the performance of the separately excited motor in addition to regulating its speed through the entire operating range. The Digital Signal Processor (DSP), besides generating the PWM gating pulse for the lone power switch in...
This paper focuses on determining the transfer function (TF) of a highly nonlinear and hysteretic piezoelectric actuator and its inverse. A system identification (SI) technique was employed based on the direct measurements of the inputoutput data from a bender type piezoelectric actuator mounted on a suitably designed platform equipped with appropriate instrumentation. Eventually, the actuator TF...
The paper presents a robust feedback control method to suppress the vibration and squeal noise phenomenon in disc brake model using an active force control (AFC) strategy. A two degree-of-freedom (2-DOF) Wagner model was considered in the study as the main dynamical element to be controlled. The system was tested for robustness and effectiveness in reducing the vibration and squeal, taking into account...
Solar hydrogen harvesting system converts the solar irradiance collected and stored in the form of compressed hydrogen instead of charges in batteries. Furthermore, oxygen released during the electrolysis process is a nonpolluting element. In this paper we present the feasibility study of solar hydrogen harvesting system using seawater instead of clean water to produces compressed hydrogen. Besides,...
Transient Stability Analysis (TSA) is a major analysis in the operation of power systems, due to the increasing stress on power system networks. One of the main goals of this analysis is to gather critical information, such as critical clearing time (tCCT) of the circuit breakers for faults in the system. tCCT is defined as the maximum time between the fault initiation and its clearing, such that...
While wireless sensor network drives the trend toward low-cost, in many industrial applications, it is not this factor that impacts on the rapid deployment of products on the markets but the rapidly changing application environment and design requirements. How to rapidly construct application software for different design requirements and operate smoothly are major challenges. An automatic embedded...

The reliability of high voltage power apparatus depends upon the careful design of its insulation and configuration of electrostatic field. The most common failure of the insulation occurs due to the surface insulation failure and the discharges within the void. In this regard, the monitoring and prevention of insulation failure becomes essential for uninterrupted functioning of high voltage power...
