Cloud computing presents a different resource allocation paradigm than either grids or distributed systems. Cloud service providers dynamically scale virtualized computing resources as a service over the internet. Due to variable number of users and limited resources, cloud is prone to deadlock at very large scale. Resource allocation and the associated deadlock avoidance is problem originated in the design and the implementation of the distributed computing, grid computing. In this paper, a new concept of free space cloud is proposed to avoid deadlock by collecting available free resource from all allocated users. New algorithms are developed for allocating multiple resources to competing services running in virtual machines on a heterogeneous distributed platform.&nbsp; An experiment is tested in CloudSim. The performance of resource pool manager is evaluated by using CloudSim and resource utilization and indicating good results.</p> Ha Huy Cuong Nguyen Van Thang Doan ##submission.copyrightStatement## 2019-01-01 2019-01-01 2 1 98 107 10.15157/IJITIS.2019.2.1.98-107 Recognition of Bearing Type by Spectrum Analysis <p>The methods of bearing condition analysis advanced much since the processor technologies had enormously raised the computational power.&nbsp; Both smaller and larger platforms have gained in computational speed. The manufacturers of portable vibration measurement devices have got the opportunity to apply such efficient but heavy tools as digital filters, convolution, fast Fourier transforms with better resolution, wavelet transforms, pattern recognition or even neural networks with 2D- and 3D-representation of data. But even then obtaining of good results is limited with multiple conditions as shown in [1]. Having solved the problem with CPU power it may seem that there are no limitations to use the hard methods. But, the electronic component’s lifetime still has the limits: read/write operations and etc. Although these limits are high, it is always good to prolong the lifetime of entire device or reduce its power consumption, or increase the diagnostic speed by using a less demanding algorithm at least at some parts of diagnostic procedure. The laboratories of bearing analysis which are commonly the part of bearing production enterprises have the best opportunities to test the bearings. The type is known, the dimensions are known. The test SW is tuned to the bearing type and the detailed diagnosis gives the best outcome. It is unlike in field service where the bearing type is unknown.&nbsp; Knowing it in the field would help to tune the vibrometer (as in laboratory) and then to switch on the heavy diagnostic methods. The purpose of this work was to create a prototype of software and the bearing model. The model would have the features enough to be determined by the frequency analysis of signal mix and recognized as a certain bearing type.</p> Roman Volis ##submission.copyrightStatement## 2019-01-01 2019-01-01 2 1 108 118 10.15157/IJITIS.2019.2.1.108-118 Design of a Robust Controller Using Sliding Mode for Two Rotor Aero-Dynamic System <p>This paper deals with two rotor aero-dynamic system (TRAS) which is a multi-input multi-output highly coupled nonlinear system, for creating a mathematical model based following the Lagrange’s Equations, and creating controllers for Sliding Mode Control and Linear Quadratic Regulator. The Sliding Manifold is designed by employing the reduced order representation. Linear Quadratic Regulator has been created by linearizing the nonlinear system acquired by creating the state space representation following the mathematical model. The signal tracking conditions of PID, SMC, and LQR have been discussed.&nbsp; Although the proposed control methodology has perfect actuation time, the tracking efficiency was not satisfactory. Therefore, a rework on the parametrization and introduction of filters, i.e. types of Kalman Filters have been proposed as a conclusion.</p> Yigitcan Coskunturk ##submission.copyrightStatement## 2019-01-01 2019-01-01 2 1 119 132 10.15157/IJITIS.2019.2.1.119-132 Study on Modeling and Simulation of HEV for Optimal Fuel Economy <p>Hybrid electric vehicle uses internal combustion engine (ICE) and electrical power for propulsion.

The system is aimed to detect faults quickly and reconfigure the controller accordingly. Thus, such system can perform its function correctly even in the presence of internal faults. An FDMB controller consists of two main parts, the first is fault detection and diagnosis (FDD); and the second is controller reconfiguration (CR). Systems subject to such faults are modelled as stochastic hybrid dynamic model. Each fault is deterministically represented by a mode in a discrete set of models. The FDD is used with interacting multiple-model (IMM) estimator and the CR is used with generalized predictive control (GPC) algorithm. Simulations for the proposed controller are illustrated and analysed.</p> Nitin Afzulpurkar ##submission.copyrightStatement## 2019-01-01 2019-01-01 2 1 160 172 10.15157/IJITIS.2019.2.1.160-172 Stabilizability Analysis of Multiple Model Control with Probabilistic Switching <p>In this paper, we derive some useful necessary conditions for stabilizability of multiple model control using a bank of stabilizing state feedback controllers. The outputs of this set are weighted by their probabilities as a soft switching system and together fed back to the plant. We study quadratic stabilizability of this closed loop soft switching system for both continuous and discrete-time hybrid system. For the continuous-time hybrid system, a bound on sum of eigenvalues of &nbsp;is found when their derivatives of Lyapunov functions are upper bounded.&nbsp; For discrete-time hybrid system, a new stabilizability condition of soft switching signals is presented.</p> Anan Suebsomran ##submission.copyrightStatement## 2019-01-01 2019-01-01 2 1 173 180 10.15157/IJITIS.2019.2.1.173-180 MATLAB-based Graphic User Interface for Monitoring and Control of Wireless Sensor Networks <p>Wireless sensor networks are becoming more popular to remote sensing applications due to their high mobility, speed, security, and cost effective. A smart sensing network can be setup with XBee modules, sensors, actuators connected to microcontrollers. However due to the limited memory and speed, embedded microcontrollers cannot perform completed and sophisticated calculations needed in a modern sensing system. Further, the design of the remote human-machine interface, interaction and control for this system is also a challenge. This paper develops a new application for a wireless smart sensor network using XBee modules and microcontrollers LPC2148. The network interfaces to the personal computer’s Matlab software for data archiving, processing and exchanging in order to improve the ability of calculation, visualization, and control of remote embedded microcontrollers via this wireless network.</p> Altunin Valeri Victor Musalimov ##submission.copyrightStatement## 2019-01-01 2019-01-01 2 1 181 191 10.15157/IJITIS.2019.2.1.181-191 Psychological Relatedness Factor influencing Performance in Archery <p>This paper serves to explain the conceptual performance in archery that affected by psychological relatedness factor. Coaches, teammates and athlete play important role in every sport. Distinguishing and understanding each factor of psychological relatedness is important in determining the athlete’s performance. The inter-relatedness between coach and athlete is vital in bringing out the best performance of athletes. Despites of having advance tools and equipment in archery, however, archer’s performance still can be fluctuated, this may be due to the intangible factor which requires more study in the context. Thus this research served the theoretical explanation that may affect the athlete’s performance. This research suggests that factor such as coach; teammate and athlete should understand the way they communicate with each other, so that the interaction between them would not affect athletes’ performance. Therefore, future research should focus more on interrelationship existed between them and factors that might influence on athletes’ performance.</p> Irza Hanie Abu Samah Abdul Shukor Shamsudin Amer Darus ##submission.copyrightStatement## 2019-01-08 2019-01-08 2 1 192 199 10.15157/IJITIS.2019.2.1.192-199 Trajectory Generation and Control of Autonomous Vehicles <p>The objective of this paper is to find feasible path planning algorithms for non-holonomic vehicles subject to their real dynamical constraints.

At the end, other controllers are presented in order to continue this work and compare their performances.</p> Thibaud Poulain ##submission.copyrightStatement## 2019-01-18 2019-01-18 2 1 200 211 10.15157/IJITIS.2019.2.1.200-211
