Compressive sensing is a new data compression paradigm that has shown significant promise in fields such as MRI. However, the practical performance of the theory very much depends on the characteristics of the signal being sensed. As such the utility of the technique cannot be extrapolated from one application to another. Electroencephalography (EEG) is a fundamental tool for the investigation of many neurological disorders and is increasingly also used in many non-medical applications, such as Brain-Computer Interfaces. This paper characterises in detail the practical performance of different implementations of the compressive sensing theory when applied to scalp EEG signals for the first time. The results are of particular interest for wearable EEG communication systems requiring low power, real-time compression of the EEG data.

Ohya and Volovich found the quantum algorithm with a chaos dynamics, called the OV SAT algorithm which enabled to solve NP-Complete problem in polynomial time. It is proved that the unitary operator of the quantum algorithm can be constructed by a product of so called fundamental gates. To discuss the computational complexity rigorously, we introduced a generalized quantum Turing machine(GQTM) where the computational process is given by quantum channels including a dispative dynamics and the configuration is represented by density operators. In this paper, we explain the GQTM and the OV SAT algorithm, then we discuss the computational complexity of OV SAT algorithm. Finally, we introduce some resent results and topics by use of GQTM.

A lot of research in the radio domain has focussed on integrating autonomy and smartness capabilities inside future radio equipments like mobile phones. Such a smart radio is called a cognitive radio. This requires complementary management facilities to be added to the radio signal processing facilities present in traditional radios. Hierarchical and Distributed Cognitive Radio Architecture Management (HDCRAM) has been proposed as a solution for managing cognitive radio equipments. HDCRAM can realize the cognitive radio paradigm by integrating all three cognitive cycle stages: sensing, decision making and real-time adaptation. This paper aims at showing an analogy between HDCRAM, a cognitive radio equipment management architecture defined for cognitive radio, and the human nervous system, including both the central and the peripheral nervous systems. This is an originality in this field, as generally electronics has only considered the copying of brain functions (neurons in particular). Obvious similarities have been identified although this was never an a priori goal. This can be verified at several levels: (i) the structure of the cognitive management itself with a general manager (brain) made of, (ii) sensors and their management (sensorial sub-system), (iii) processing functions and their configuration management (motor sub-system), (iv) but also mechanisms which are very close to the biological model, such as reflex principle for real-time reactivity.

This paper describes the practical design issues and potential strategies for implementing cognitive radio (CR) equipments that support spectrum agility. We first discuss a simplified cognitive cycle that satisfies the requirements of a typical CR scenario. We give a brief overview of the various steps involved in the above cycle, namely, sensing, decision making and flexible signal processing. A management architecture called HDCRAM (Hierarchical and Distributed Cognitive Radio Architecture Management) is proposed as a solution for efficiently managing all the steps in the cognitive cycle. Finally we give an integrated proposal, which serves a starting point for designing future spectrum agile CR equipments.

An interferometric radar operating between 6 and 9 GHz for non-invasive measurement of the respiration rate, is presented. An adaptive RF front-end tracks slow body movements by changing the operating frequency such that the sensing system always operates in its optimum point. Experimental results have been obtained from human beings and the good correlation between the radar signals and a reference signal obtained from a conventional respiratory sensor show the validity of this approach.

Blast-induced traumatic brain injuries have become the signature injury of the current conflicts in the Middle East, due to the emergence of improvised explosive devices (IEDs) as the weapon of choice by insurgents. Significant efforts are made by the medical and scientific communities to investigate the source and mechanisms related to that type of injury. To collect information related to the intensity of the blast events to which soldiers are exposed to in the field, a helmet-mounted blast dosimeter has been developed to track the acceleration and pressure field at the soldier helmet level. While initial proof of concepts had confirmed the appropriateness of the device in terms of correlating readings with corresponding dynamic motion of a soldier's head, significant electronics and signal processing challenges remained to be addressed and solved. The data from the unit can be downloaded to a computer system for further analysis. Thousands of units of the original concept were fielded by the US Military in the Middle East.

Performance of classification methods using Machine Learning Techniques majority depends on the quality of data were used in learning. The transformation techniques are used to increase the efficiency of classification because each type of data is suitable for different classification techniques. This study is aimed at providing comparative performance of different classification techniques by changing the type of data to find the appropriate type of data for each technique. The ß-Thalassemia data is used for classifying genotypes of ß-Thalassemia patients. The results of this study show that the types of data are Nominal scale which can be used as well for Bayesian Networks (BNs) and Multinomial Logistic Regression with the percentage of accuracy 85.83 and 84.25 respectively. Moreover, the data types which such as Interval scale can be used appropriately for K-Nearest Neighbors (KNN), Multi-Layer Perceptron (MLP) and NaiveBayes with the percentage of accuracy 88.98, 87.40 and 84.25 respectively. In the future, we will study the impacts of data separation to be used for classifying genotypes of patients with Thalassemia using the other classification techniques.

ICT technology and solutions are always more deployed in the healthcare sector, both in the private and in the public sectors. Health related information is sensitive data, which under the law has to be collected and processed in compliance with strict privacy and security requirements. Implementation of ICT technology in the Healthcare sector has therefore to take into careful consideration the applicable privacy and data security legal framework.

This paper describes wireless wearable and ambient sensors that cooperate to monitor a person's vital signs such as heart rate and blood pressure during daily activities. Each wearable sensor is attached on different parts of the body. The wearable sensors require a high sampling rate and time synchronization to provide a precise analysis of the received signals. The trigger signal for synchronization is provided by the ambient sensors, which detect the user's presence. As wireless technologies, Bluetooth and IEEE 802.15.4 are used for real-time sensing and time synchronization. Thus, this wearable health-monitoring sensor response is closely related to the context in which it is being used. Experimental results indicate that the system simultaneously provides information about the user's location and vital signs, and the synchronized wearable sensors successfully measures vital signs with a 1 ms resolution.

Bodyworn tags are a challenging application for radio frequency identification (RFID) systems. The importance of this application will increase in the future due to emerging novel wireless identification and sensor systems. In this paper, a literature survey of wearable RFID tag antennas is presented. One-layer and multilayer tags are compared. The body effect on antenna parameters is analysed. Based on the findings, guidelines for wearable tag antenna design are given. As an example of a bodyworn tag, a meandered dipole is presented.
