Drivers' distraction is widely recognized as a leading cause of car accidents. To investigate the distracting effect of dual-tasks involving driving and answering mathematical equations in the stimulus onset asynchrony (SOA) conditions, we design five different cases: two cases involving single-tasks and three cases involving dual-tasks. We have found that there is no statistically significant change in the behavioral data among the three dual-tasks. This raises an important question - is there any detectable effect of the dual tasks on the brain waves? To answer this, we use the Self-Organizing Map (SOM) to recognize the changes, if any, in the Electroencephalography (EEG) dynamics associated with such dual-tasks. Our SOM analysis based on independent components corresponding to EEG signals extracted from Frontal and Motor areas revealed that single- and dual-tasks have distinguishable signatures in the EEG signals. Specifically, each of the two single-task conditions is clustered in a distinct spatial area of the map. Two of the dual-tasks also exhibit distinct spatial clusters, while the third case although shows differences from the other two, the neurons corresponding to this case are sub-clustered reflecting the fact that different subjects may give different priorities to the tasks when confronted with two tasks simultaneously. SOM-based exploratory analysis reveals the existence of distinct EEG signatures among the distracting and non-distracting tasks, although there is no any noticeable difference in the behavioral data among these cases. © 2010 IEEE.

Meta-heuristics are efficient techniques for solving large scale optimization problems in which traditional mathematical techniques are impractical or provide sub-optimal solutions. The Shuffled Frog Leaping algorithm (SFLA) is a stochastic iterative method, bio-inspired on the memetic evolution of a group of frogs when seeking for food, which combines the social behavior-based of the particle swarm optimization technique (PSO) and the global information exchange of memetic algorithms. However, the SFLA algorithm suffers on large execution times, being this problem clearly evident when solving complex optimization problems for embedded applications. This drawback can be overcome by exploiting the parallel capabilities of the SFLA. This paper proposes a hardware parallel implementation of the SFLA algorithm (HPSFLA) using FPGAs (Field Programmable gate Arrays) and the efficient floating-point arithmetic. The proposed architecture allows the SFLA to improve the functionality of the algorithm as well as to decrease the execution times by implementing parallel frogs and parallel memeplexes. Three well-known benchmark problems have been used to validate the implemented algorithm and simulation results demonstrate that the HPSFLA speeds-up by factors of 362, 727 and 211 a C-code implementation using an embedded microprocessor for the Sphere, Rastrigin and Rosenbrock benchmarks problems, respectively. Synthesis, simulation and execution time results demonstrate the effectiveness of the proposed HPSFLA architecture for embedded optimization systems. © 2010 IEEE.

The purpose of this project is to allow a free movement of Building Management System (BMS) operator in all controlled building area. The current state of the problem consists in an impossibility of operator's movement from control centre. We found a solution in using of mobile devices like PDA with a client of BMS to allow a remote access to all alarms of system. Solution consist in use of web services and web methods interface on BMS server, where is possible to connect a remote PDA client to interchange a requested info about alarms and trends. A web services and mobile client application was created using a Microsoft Visual Studio 2008. Future trends are also discussed to provide a solution for small and mid size constructions in direction of use a Microsoft .NET Micro Framework. © 2010 IEEE.

The purpose of this work is the implementation of the program code that enables digital filtration on aJ-80 embedded JAVA processor. While working the implementation filter we need to provide the fastest calculation with the greatest accuracy. Next, it is almost always necessary for the results to be available after the same time from the sample upload. These matters determine the digital filtration as a problem called RT, which is the problem suitable for testing of the processor aJ-80 and its RT features. The work also describes the chosen task example, which examines RT features of this processor. We also mention the attained results and their evaluation. Based on the evaluation, the performance of the hardware program of the processor aJ-80 is very effective. In this respect, the product is recommended to use in many hard RT areas. © 2010 IEEE.

Business forecasting uses statistic tools more or less sophisticated that relay on the observation values from the past, regarding the activity level, and calculates predictions for the future. The majority of the methods can calculate forecast without any problem and with high accuracy when the data has a satisfying quality. This paper describes our results in implementing the forecast in general and highlights the cases with sporadic data, cases with a high forecasting need, that are common in real life.

According to the intelligent behavior of social population, a novel particle swarm optimization algorithm based on predatory search strategy (PS-CPSO) is proposed by introducing the centroid of particle swarm in the standard particle swarm optimization model to improve global optimum efficiency and accuracy of algorithm. Results of Benchmark function simulation and material balance computation (MBC) in alumina production show that the new method not only improves the local searching efficiency and global searching performance greatly, but also has faster convergence speed and higher precision, and can avoid the premature convergence problem effectively.

Over the last two or three years, the increasing costs of energy, greater awareness of environmental concerns and worsening market conditions have focussed even greater attention within paper mills than before, on considering ways to reduce the energy used in paper making. Arising from a multivariable understanding of paper machine operation, Advanced Process control (APC) technology enables paper machine behaviour to be controlled in a more coherent way, using all the variables available for control. Furthermore, with the machine under better regulation and with more variables used in control, there is the opportunity to optimise machine operation, usually providing very striking multi-objective performance improvement benefits of a number of kinds. Traditional three tem control technology does not offer this capability. The paper presents results from several different APC paper machine projects we have undertaken around the world. These projects have been aimed at improving machine stability, optimising chemicals usage and reducing energy use. On a brown paperboard machine in Australia, specific steam usage has been reduced by greater than 10%, averaged across the grades;the controller has also provided a significant capacity to increase production. On a Canadian newsprint machine the APC system has reduced steam usage by 10%, and it provides better control of colour and much improved wet end stability. The paper also outlines early results from two other APC projects being undertaken in England, each aimed at examining a different approach to reducing the energy used in paper making. The first of these two projects is focussed on optimising sheet drainage, aiming to present the dryer with a sheet having higher solids content. The second project aims to reduce specific steam usage by maximising machine production. The paper concludes with an outline of a project just begun in which better understanding is being sought of the role of differential pressure and cond

A non-linear iterative learning control approach is developed for application to stroke rehabilitation. The subject is seated in a robotic workstation and electrical stimulation is applied to their triceps muscle to assist the tracking of trajectories in a horizontal plane. In addition to rotation about vertical axes through the shoulder and elbow joints, the forearm is also permitted to elevate in order to provide full arm extension. A dynamic model of the human arm is first developed, and then constraints are introduced to overcome kinematic redundancy. The expressions necessary to implement the control law are derived, and experimental results confirm its ability to achieve a high level of performance in practice. © 2010 AACC.
