Analyzing DNA microarray data pose a serious challenge because of their large number of features (genes) and relatively small number of samples. Extracting features, those have predictive capability for classifying these huge datasets demands appropriate approaches like feature reduction and identifying optimal set of genes. In this paper along with conventional statistical methods like filtering the dataset to reduce the number of features, one additional approach of evaluating correlation between the classes for each feature is performed. Proposed approach yields higher classification accuracy for both Acute Lymphoblastic (ALL) and High Grade Glioma cancer dataset than using only traditional statistical filtering methods.

The increased penetration of renewable energy sources and the concept of a dynamic and highly distributed Smart Grid which can intelligently integrate production units, storage systems and connected users opened new challenges in the application of optimization techniques. In this work, a dynamic optimization problem is formulated on a power grid characterized by wind and photovoltaic production units, conventional power plants, biomass co-generation and storage systems. A Model Predictive Control (MPC) scheme is adopted in the dynamic decision model for real time purposes. The decision problem takes into account the network load flows constraints and a state equation related to the state of charge (SOC) of the batteries. Different issues (economic, technical, environmental, security) have been taken into account for the formalization of the objective function. Numerical results are finally reported and discussed. © 2012 IEEE.

This paper is for the study of feature analysis of the correlation of brain waves between channels in the stimulation of the 5 senses (sight, hearing, touch, smell, taste). In the existing studies, feature analysis of brain waves in response to stimulation of the human senses has been made by single sense stimulation or double sense stimulation, but, study with stimulation of all 5 senses is still not yet satisfactory. In this paper, the brain waves in response to stimulation of the 5 senses in the behavior of eating food are collected and analyzed for the analysis of the features of brain waves. From time-based data and frequency elements, features of correlation in brain waves between channels are extracted. The overlapping rates between the stimulation sections, between experimenters, and between frames consisting of channels with high correlation coefficients are calculated. In the experiment, 65 sections (32 stimulation sections, 33 break sections) of a brain wave database (DB) about the stimulation of the 5 senses were collected and analyzed for 9 men and 2 women. In the results of the experiment, the stimulation is distinguishable for each sense.

systems on Chips (SoCs) architecture complexity is result of integrating a large numbers of cores in a single chip. The approaches should address the systems particular challenges such as reliability, performance, and power constraints. Monitoring became a necessary part for testing, debugging and performance evaluations of SoCs at run time, as On-chip monitoring is employed to provide environmental information, such as temperature, voltage, and error data. Real-time system validation is done by exploiting the monitoring to determine the proper operation of a system within the designed parameters. The paper explains the common monitoring operations in SoCs, showing the functionality of thermal, voltage and soft error monitors. The different architectures that are approached by the research community until now are discussed.

A method for detecting spikes and slow burst in photic evoked electroencephalogram (EEG) was proposed. The spikes were detected by combining methods of the morphological filter and the similarity coefficient in the time domain. The slow burst was detected by using pole of AR model (auto-regressive model) in the frequency domain. The proposed method was applied for the photic evoked EEG data containing spikes and slow burst, and brought satisfactory coincidence with the results interpreted by a qualified electroencephalographer. © 2012 IEEE.

The theory of the plasmon resonance excitation in the plasmonic-crystal structure on a dielectric substrate is presented. The effect of the plasmon resonance intensity oscillation as a function of the substrate thickness is predicted. It is shown that the enhancement of the plasmon resonance intensity occurs in a broad terahertz frequency range in the structure on a membrane substrate. © 2012 Allerton Press, Inc.

Dangerous goods transportation (DGT) is a relevant safety and security issue that has been treated in many papers in the last decades. Considering the significant damages that a DGT accident can cause, a DGT routing strategy is to avoid the worst case accident scenario, following a risk-averse behaviour. Game-theory is very useful in this context. Taking into account a DGT flow on a road network and the technologies for vehicle/infrastructure communication which are nowadays available, the overall context can be modelled as a system of systems, where a team of road segments concurs to find an optimal strategy to minimise the maximum risk on the territory. Two problems related to DGT are presented and preliminary formulations, at operational and at real-time level, are described. A solving method based on linear matrix inequalities is shown and first results are shown.

We propose a generalised diffusion-based file replication scheme for load balancing in unstructured P2P file-sharing networks. The generalised method is derived by replacing the replication probability of a peer used in our previous study with a new expression. In the previous expression, the replication probability is defined to be proportional to the difference between its own load and the average load of its neighbour peers. We show here that the replication probability can instead be expressed as a simple average of one defined to be negatively proportional to its own load and one defined to be proportional to the average load of its neighbour peers. The generalised method (a) includes the above three methods as special cases, (b) can control the trade-off between search and load balancing performances, (c) has a physical analogy to diffusion phenomena, and (d) achieves a good balance in the trade-off differently from our previous method.

The new paradigm in mobile services lies in providing a location-based user experience and here lies the tremendous scope for expansion of location-based services (LBS). One of the key approaches that have been recognized as an enabler of such a view is policy-based management, which has been mostly acknowledged as a methodology that provides adaptability and support to automatically assign network resources, control Quality of Service and security, by considering administratively specified rules. Whilst current research focuses mostly on rules for low-level device configuration, significant challenges remain to be addressed in order to provide dynamic adaptation of policy in response to changes and ensure that policies will lead to a feasible implementation within the managed environment. In this paper, the emphasis is on building the described environment using today's existing technologies. We use our policy-based framework PobMC to combine mobile (location-based) services, ubiquitous and autonomic computing concepts. The goal is to bring the kind of informationrich environment, which is currently limited to computer screens, to the real world. This is achieved by constructing an architecture based on existing wireless network technologies and Web applications. Location information of destinations and users is computed by the received signal strength indicator (RSSI) values of the Wi-Fi sensors, to provide adaptive services over wireless Web. The users use their mobile devices to access these location-based services.

Image segmentation is the most important step and a key technology in image processing which directly affect the next processing. In human blood cell segmentation cases, many methods were applied for obtaining better results. It is basically an improved visualization to observe blood cell under blood smear process. This paper will present an approach for red blood cell (RBC) segmentation which is a part of study to perform automated counting for RBC. The methods involve are Ycbcr color conversion, masking, morphological operators and watershed algorithm. The combination of Ycbcr color conversion and morphological operator produce segmented white blood cell (WBC) nucleus. Then it is being used as a mask to remove WBC from the blood cell image. Morphological operators involve binary erosion diminish small object like platelet. The resulted RBC segmentation is passing through marker controlled watershed algorithm which handles overlapping cells. The improvement need to be done for both segmentation and overlapped cell handling to obtain better result in the future.
