The main purpose in this work is to enhance relay technique in underlay cognitive radio scheme through estimating the best path between the secondary source and the secondary destination under the power interference constraint of the primary user. A protocol is proposed based on the cooperation process between the secondary relay nodes in the system in order to establish the best path at low complexity without exceeding the interference threshold of the primary user. Performance analyses, through simulation, of the suggested protocol shows great enhancement in network outage probability when compared with direct path model and one relay node based-model.

We propose an innovative overlay architecture among heterogeneous devices that works on different operating systems and an application based on standard web technologies that leverages on such architecture to perform a broad range of functions using audio commands. To achieve this, a secure web runtime platform allows connecting different devices such as an Android mobile device, a single board computer and a Web of Things (WoT) sensor/actuator in a secure and independent manner. Methods and functions have been created in order to capture the audio from the microphone on personal computers and on mobile phones, and to safely transfer files to a single board computer, in which a speech recognition engine is embedded. Therefore, by recording the audio command from one of these devices and performing voice command identification using the speech engine, it is possible to perform different actions previously defined by the user on one of his devices. This work demonstrates how open source platforms can interconnect and operate with proprietary architecture in a complementary and secure manner.

This research paper deals with Reconfigurable Hardware Systems (abbreviated, RHS) that should be adapted to their environment under well-defined conditions. A reconfiguration scenario is a run-time hardware operation allowing the addition/removal of hardware components. We classify the reconfiguration scenarios into three levels: Architectural, Structural and Data Reconfiguration Levels. We propose a new solution for optimal hardware tests of RHS based on the definition of new fault collapsing relationships termed Inter-Equivalence, Inter-Dominance and Redundancy.

Public display systems are becoming increasingly complex. They are moving from passive closed systems to open interactive systems that are able to accommodate applications from several independent sources. This shift needs to be accompanied by a more flexible and powerful application management. In this paper, we propose a run-time life-cycle model for interactive public display applications that addresses several shortcomings of current display systems. Our model allows applications to load their resources before they are displayed, enables the system to quickly pause and resume applications, provides strategies for applications to transition and terminate gracefully by requesting additional time to finish the presentation of content, allows applications to save their state before being destroyed and gives applications the opportunity to request and relinquish display time. We have implemented our model as a Google Chrome extension that allows any computer with the Google Chrome browser to become a public display driver without further software. In this paper we present our model, implementation, and evaluation of the system.

Recently, 3rd Generation Partnership Project (3GPP) has developed sidehaul system to cope with the explosively increasing mobile data traffic. The sidehaul system is based on single carrier-frequency division multiple access (SC-FMDA) due to its low peak-to-average power ratio (PAPR). Also, demodulation reference signal (DMRS) is designed to support multiple input multiple output (MIMO). In this paper, we propose the DFT-based channel estimation scheme for sidehaul system. The proposed scheme uses the 2-dimensional minimum mean square error (2-D MMSE) interpolation scheme for the user moving at a high speed. Simulation results show that the proposed channel estimation scheme can improve normalized mean square error (NMSE), error rate and throughput of conventional system.

In our daily life, we often have a sense of being exhausted due to mental or physical work, together with a feeling of performance degradation in the accomplishment of simple tasks. This is in part due to the fact that the working capacity and the performance of an individual, either physical or mental, generally decrease as the day progresses, although factors like motivation also play a significant role. These negative effects are especially significant when carrying out long or demanding tasks, as often happens in an educational context. In order to avoid these effects, initiatives to promote a good management of the time and effort invested in each task are mandatory. Such initiatives, when effective, can have a wide range of positive effects, including on the performance, productivity, attention and even mental health. Seeking to find a viable and realistic approach to address this problem, this paper presents a non-invasive and non-intrusive way to measure mental workload, one of the aspects that affects mental fatigue the most. Specifically, we target scenarios of e-learning, in which the professor may not be present to assess the student's state. The aim is to create a tool that enables an actual management of fatigue in such environments and thus allows for the implementation of more efficient learning processes, adapted to the abilities and state of each student.

In recent years, a substantial work has been devoted to the design of cryptographic protocols with reduced computational load and power consumption. However, implementations are scarce, especially in case of embedded devices. In this paper, we discuss the implementation over elliptic curves of a two-party key agreement protocol for the Raspberry PI platform. The protocol requires just one round to derive an (implicit) authenticated session key, and it makes use of identity-based cryptography, which fits very well some application scenarios, allowing for more efficiency than the certificate-based approach. Our implementation takes advantage of the portability and security features of the Java programming language and, due to a modular design, it can be easily extended to encompass other identity-based schemes and protocols. We run a set of tests in order to verify the correctness of our implementation and to measure its performances in term of computing time. Our results demonstrate that getting secure communications using low cost, resource constrained devices is viable to the point that it can be used for real world applications.

In this paper, a bit-inverted Gray coded bit-plane matching algorithm is proposed for low complexity motion estimation. Unlike the typical Gray coded bit-plane matching algorithms, the proposed algorithm uses bit-inverted Gray codes for transforming image frames and a corresponding extended matching criterion to enhance the motion estimation accuracy. Experimental results show that the proposed algorithm outperforms other bit-plane matching based motion estimation algorithms while preserving the binary matching characteristic.

This paper describes the architecture and functionality of a generic agent that is in charge of handling a given environment in an Ambient Intelligence context, ensuring suitable contextualized and personalized support to the user's actions, adaptivity to the user's peculiarities and to changes over time, and automated management of the environment itself. The architecture is implemented in a multi-agent system, where different types of agents are endowed with different levels of reasoning and learning capabilities. In addition to controlling normal operations of the environment, the system may identify user's needs and goals and activate suitable workflows to satisfy them. Some actions in these workflow involve the execution of semantic services. When a single service is not available for fulfilling a given need, an automatic service composer is used to obtain a suitable combination of services. The architecture has been implemented in a prototypical agent-based system that works in a Smart Home Environment.

Recently, closed-form approximated expressions were obtained for the residual Inter-Symbol Interference (ISI) obtained by blind adaptive equalizers valid for the real or two independent quadrature carrier case such as the 16 Quadrature Amplitude Modulation (QAM) input. In this paper we propose for the complex and dependent quadrature carrier case (such as the 32QAM source), a closed-form approximated expression for the achievable residual ISI which depends on the step-size parameter, equalizer's tap length, input signal statistics, channel power and SNR. This approximated expression is applicable for blind adaptive equalizers where the error is fed into the adaptive mechanism, which updates the equalizer's taps and can be expressed as a polynomial function up to order five of the equalized output. Godard's algorithm for example, applies a third order polynomial function to the adaptation mechanism of the equalizer thus belongs to the above-mentioned type of equalizers. Since the channel power is measurable, or can be calculated if the channel coefficients are given, there is no need to perform any simulation with various step-size parameters and different values of SNR to reach the required residual ISI for the dependent quadrature carrier input case.
