This paper investigates the application of a recursive synchronization technique that can be applied to chaotic systems, using a single time series. The Unified system is used to exemplify the chaotic systems due to its versatile characteristics. The proposed method doesn't require the direct construction of an error signal between the measurable state and its estimate; thus, allowing for easily constructing a reduced-order state observer. Proving the stability of the synchronization mechanism is done using a systematic Lyapunov-based approach. Adjusting the decay rates of the synchronization errors is achieved by tuning of the proposed observation gains of the system. It is demonstrated that different sets of gains can be chosen to achieve a stable satisfactory performance, which is an added advantage to the proposed system. Different scenarios that include the Lorenz, the Lü, and the Chen systems are explored to provide a rich comparison between the proposed system and other synchronization techniques, reported in the literature. Extensions, improvements, and possible real-world applications are also discussed to complete the analysis of the recursive nature of the proposed system. © 2016 IEEE.

Modern computing systems are hybrid in nature and employ various processing technologies that range from specific-To general-purpose processors. In co-design environments, specific-purpose processors, also known as hardware, work to support software implementations under general-purpose systems to create high-performance computers. Algorithms and computationally intensive tasks are partitioned among the different processing subsystems to achieve desirable degrees of parallel processing and performance characteristics. In this paper, a unified statistical performance analysis formulation is presented. The proposed statistical formulation combines the heterogeneous characteristics of both hardware and software implementations to provide grounds for thorough evaluations. The formulation includes the development of performance profiles, key indicators, and the composition of a master indicator based-on heterogeneous measurements. The investigation includes a case-study that targets a set of simple cryptographic algorithms. The two main targeted high performance computing devices are multicore processors for software implementations and high-end Field Programmable Gate Arrays for hardware implementations. © 2016 IEEE.

A new radiation pattern reconfigurable antenna is designed and fabricated. The antenna is able to radiate in four orthogonal directions in the azimuth plane and sweep the whole azimuth. The radiation pattern reconfigurability is obtained using the passband and stopband characteristics of EBG surfaces which are used to form EBG panels to surround the feeding dipole centered in the structure. Switching between passband and stopband is implemented using active elements in the structure. © 2017, Electromagnetics Academy. All rights reserved.

The class of foraging algorithms is a relatively new field based on mimicking the foraging behavior of animals, insects, birds or fish in order to develop efficient optimization algorithms. The artificial bee colony (ABC), the bees algorithm (BA), ant colony optimization (ACO), and bacterial foraging optimization algorithms (BFOA) are examples of this class to name a few. This work provides a complete performance assessment of the four mentioned algorithms in comparison to the widely known differential evolution (DE), genetic algorithms (GAs), harmony search (HS), and particle swarm optimization (PSO) algorithms when applied to the problem of unconstrained nonlinear continuous function optimization. To the best of our knowledge, most of the work conducted so far using foraging algorithms has been tested on classical functions. This work provides the comparison using the well-known CEC05 benchmark functions based on the solution reached, the success rate, and the performance rate. © 2011 Elsevier Inc. All rights reserved.

IEEE 802.15.4 is the de facto standard for Wireless Sensor Networks (WSNs) that outlines the specifications of the PHY layer and MAC sub-layer in these networks. The MAC protocol is needed to orchestrate sensor nodes access to the wireless communication medium. Although distinguished by a set of strengths that contributed to its popularity in various WSNs, IEEE 802.15.4 MAC suffers from several limitations that play a role in deteriorating its performance. Also, from a practical perspective, 80.15.4-based networks are usually deployed in the vicinity of other wireless networks that operate in the same ISM band. This means that 802.15.4 MAC should be ready to cope with interference from other networks. These facts have motivated efforts to devise improved IEEE 802.15.4 MAC protocols for WSNs. In this paper we provide a survey for these protocols and highlight the methodologies they follow to enhance the performance of the IEEE 802.15.4 MAC protocol. © 2014 IEEE.

The Artificial Bee Colony (ABC) algorithm is a relatively new algorithm for function optimization. The algorithm is inspired by the foraging behavior of honey bees. In this work, the performance of ABC is enhanced by introducing the concept of opposition-based learning. This concept is introduced through the initialization step and through generation jumping. The performance of the proposed opposition-based ABC (OABC) is compared to the performance of ABC and opposition-based Differential Evolution (ODE) when applied to the Black-Box Optimization Benchmarking (BBOB) library introduced in the previous two GECCO conferences.

Purpose - The paradigm shift in global competition and the resulting business challenges have led manufacturing enterprises, particularly in the developing world, to take a different look at their operations. Responding to this climate meant reassessing their competitive advantage, and re-engineering their business models and operations. The purpose of this paper is to discuss many of these new challenges and present potential solutions from the practitioner point of view. Design/methodology/approach - This paper discusses many of these new challenges and presents potential solutions. The results are from interviews with the enterprise managers and owners. Findings - The issues are divided into three categories based on who can manipulate them: regional and international, national, and enterprise factors. The level of enterprises' ability to respond to these issues varies from full control to partial or no control. Nevertheless, issues' impact could be minimized by certain adopted polices and action plans. Practical implications - The paper creates a guiding compass for developing countries' manufacturing enterprises, by which they can navigate around the arising challenges, in a well-rounded, comprehensive overview. Originality/value - The paper lays a foundation for a road map for researchers and practitioners to assist small and medium-sized enterprises in becoming more competitive and improving their survivability, in a well-rounded, comprehensive way. © 2012 Emerald Group Publishing Limited.

In this paper, we investigate the periodicity of the solutions of the stochastic system of rational difference equations xn= a/y n-p, yn = b/xn+p-2(p≥1), and we develop a new analytic technique to solve it, where a, b, x0 = N y0 = M are independent random variables. © 2011 American Institute of Physics.

In this paper we test a hybrid Particle Swarm Optimization (PSO) and Artificial Bee Colony (ABC) algorithm on the CEC13 testbed. The hybridization technique is a component-based one, where the PSO algorithm is augmented with an ABC component to improve the personal bests of the particles. © 2013 IEEE.
