This paper introduces a systematic approach to synchronize identical Nosé-Hoover systems that can have multiple number of thermostats. Synchronization is achieved via using a Lyapunov-based approach for which both stability and performance satisfaction are investigated. Both modeling and simulation of the system are presented using different scenarios to verify its similarity to chaotic systems that...
The Adaptive/Approximate Dynamic Programming (ADP) is an online design approach proposed to make possible the implementations in real time of optimal controllers based on Hamilton-Jacobi-Bellman (HJB) equation solution. In this paper, ADP schemes are presented in a Heuristic Dynamic Programming (HDP) framework, where Policy Iteration (PI) strategies in conjunction with Recursive Least Squares (RLS)...
Software applications have become an indispensable integral part of this world. In all areas of everyday life they are used to store information. Users of software applications rely on the data correctness. Incorrect data within the data set can cause a reduced user acceptance. To avoid incorrect data sets the process of knowledge discovery in databases (KDD) is a powerful instrument. The application...
Accurate individual anatomical joint models are becoming increasingly important for both realistic animation and diagnostic medical applications. A number of recent approaches have exploited unit quaternions to eliminate singularities when modelling orientations between limbs at a joint. This has resulted in the development of unit quaternion based joint constraint validation and correction methods...
Different types of serious games have been used in elucidating computer science areas such as computer games, mobile games, Lego-based games, virtual worlds and webbased games. Different evaluation techniques have been conducted like questionnaires, interviews, discussions and tests. Simulation have been widely used in computer science as a motivational and interactive learning tool. This paper aims...
The reconfigurability may be required in operating frequency, radiation pattern and/or polarization of the antenna. Application areas that drive the development of reconfigurable antennas include multifunction wireless devices, WLAN, multiple-input multiple-output (MIMO), ultra-wideband (UWB) systems, anti-jamming and secure communication. Recent technologies enable electronic and RF circuits in radar...
Challenges faced by Medium access control (MAC) protocols for Wireless Sensor Networks (WSNs) include energy efficient operation and bandwidth limitations. Low duty cycle MAC conserves energy but at the same time it affects delivery ratio and latency. Use of multiple channels can improve the throughput and latency by alleviating the bandwidth limitations. This paper presents the design and performance...
To reduce the cost of network-wide broadcast in wireless sensor networks (WSNs), it's a common practice to establish a connected dominating set (CDS). A lot of algorithms have been proposed to construct CDS, and most of them aim at reducing the size of the created CDS. Existing distributed algorithms require that all nodes exchange announcement messages to acquire local topology in order to construct...
To overcome the issue of the fast decay of the magnetic fields of a magnet over distance, a device constructed of a highly permeable material was developed, aiming to focus the magnetic fields at a sensing point, hence named "field focuser". This device allows designers to increase distances between magnet and sensor, chose weaker and cheaper magnets and work with simpler 1D magnetic sensors...
Inventory is carrying high risk and high benefit as a supply chain management system. A shortage or lack of supplying sufficient inventory can disrupt manufacturing plan. Inventory management plays an important role to avoid shortage or ending up with overstock. The most important task of inventory management is making trade-off between the minimization of the total cost and maximization of the customer...
This work focus on the application of Fuzzy-Backstepping controller, based on optimization method, for trajectory tracking problem. The control algorithm based on the errors in postures of mobile robot which feed to the Fuzzy-Backstepping controller to generate correction signals that transport to torque for each driven wheel. By means of dynamic model of mobile robot, these torques are used to compute...
The study of complex networks has attracted the attention of many research in recent years due to their potential to describe complex systems. Identifying potential missing links in networks has a wide range of applications. In this paper, we propose a new approach for solving link prediction problem based on a hidden variables model. Recent studies suggest that real networks have underlying hidden...
The main objective of this study is to generate an optimum solution for capacity planning and appointment scheduling issues, which are frequently encountered in clinical flows with various route and treatment periods at dental hospitals. With this study, given the flow of different existing treatment processes belonging to patients are optimized, and also the continuity of the system is ensured by...
Genetic Algorithms are designed to find the accuracy of approximated solutions in order to perform as effectively as possible. This paper present a new way for genetic algorithm to solve NP-Complete problem. We study genetic algorithm to find an optimal solution for instances of the Traveling Salesman Problem. To overcome this solution, we have to see what is the shortest path that satisfies all of...
Electromyogram signal is a biomedical signal that measures electrical activity produced in a muscle during its contraction. This work presents a prototype system for moving a prosthetic lower arm, without prior operation intervention, using electrodes that measure electromyogram (EMG) signals placed on two muscles only. The signals are then read by sensors connected to Arduino microcontroller, processed...
Gamification is a recent phenomenon that emphasizes the process of incorporating game elements, for a specific purpose, into an existing system in order to maximise a user's experience and increase engagement with the system. In this paper, we discuss the effects of the introduction of the principles of gamification to a system for solving real-world container loading problems in a warehouse environment...
Imaging in the visible spectrum demonstrates difficulties in recognizing the faces in conditions of varying illumination, especially under total darkness conditions. Further, the pose variations in such images add extra burden and heavy challenge on successful performance. As such, thermal face recognition has laid itself as a successful alternative solution and eventually has become an area of growing...
