The paper presents a wearable wireless system and a proprietary algorithm along with a preliminary study on the time gait variability analysis as a tool for early diagnosis. The system is non-invasive and it is composed by a set of Inertial Measurements Units (IMUs) positioned on the patient leg. Each unit in the set bases its operations on Bluetooth Low Energy (BLE) standard. Experimental results validating system capabilities are reported and discussed.

Solar panel efficiency is an essential parameter in determining the cost of converting solar energy into electrical energy. This paper addresses a technique for maximizing energy extraction from photovoltaic (PV) solar systems using power electronic circuits to achieve maximum power point tracking. Design and implementation details are presented, illustrating the perturbation and observation algorithm based on DC-DC power converter. Simulations are done in Matlab/Simulink environments, and experimental implementation is conducted in a developed PV testbed. Analysis of the recorded results reveals the potential of the presented techniques in enhancing the efficiency of energy extraction from PV systems.

Vehicular networks are increasingly gaining popularity among researchers for their potential to enable diverse applications associated with road traffic safety, infotainment and road transportation management. In this paper we present a QoS-based routing protocol named VanetQoS which purpose is to accommodate real-time and multimedia applications with specific quality of service (QoS) requirements. Therefore, routing such applications data over a vehicular ad hoc networks (VANET) consists of selecting the most appropriate route that complies with required QoS. Our proposed protocol uses an algorithm which is based in multi-constraint path (MCP) problem, and which essential task is the selection of the best path among several available ones, by using and evaluating a composite formula expressed in terms of the QoS requirements such as required bandwidth, maximum delay and jitter, and minimum link expiry time. In this paper we present the architecture and design of our protocol, and provide performance results, which show the benefits of using our scheme for the purpose of routing multimedia traffic in VANET. The performance evaluation is achieved through simulation experiments using OMNET++ simulator.

One of the common means of delivering e-government services to citizens is via Web sites. Building a Web site and publishing it to them should be the beginning of the service cycle, not its end. In other words, it is essential to evaluate the user satisfaction with the design and delivery of online services. To that end, and as a case study, we evaluate the e-services of one of the local e-governments in the United Arab Emirates and link the satisfaction of users to the design of the portal. We collect data from users using a customized SERVQUAL survey and analyse data using the Two Dimensional Mean Value Matrix (TDMVM) method in order to spot what services are most important to users and to what extent they are satisfied with them.

This paper investigates memristor based demodulators and proposes new circuit designs for Binary Frequency Shift Keying (BFSK) and circular 8-Quadrature Amplitude Modulation (QAM) demodulators using two memristors at most. The proposed designs consider utilizing the unique features of the memristor element, crucially, its variable average memristance with the amplitude, phase and frequency of the sinusoidal excitation signal. The proposed QAM demodulator eliminates the need for any carrier recovery circuits. Moreover, both of the proposed QAM and BFSK demodulators are all passive circuits. The designs are further verified by the transient circuit simulations using the memristor linear dopant drift model.

This paper presents a new design of compact coplanar waveguide (CPW)-fed patch antenna for UWB operation. The shape of the patch is obtained by choosing the six different parameters of the closed form superformula, resulting in a circular patch with sawtooth-like circumference. Simulation results demonstrate that the derived antenna operates in the FCC band (3.1–10.6 GHz) for UWB operation. In comparison to the conventional CPW-fed-circular patch antenna whose optimal diameter is 25 mm, the circular patch of the proposed design has a diameter of 18.2 mm. Moreover, the proposed antenna has an improved group delay, with similar radiation and gain characteristics. Simulation results using HFSS are provided to verify the design and performance.

The potential of cost efficiency of Zero Energy Buildings has not been tackled widely so far. The market of Zero Energy Buildings lacks reliable and cost effective data logging and measuring devices of energy parameters in Buildings. The research group at the Aerospace School of Madrid has addressed the gap by developing wireless sensors to enable energy-supply by means of PV microcells. The challenge for those devices consists of the need of sending data every minute without being affected by the lack of sun. The aim of this paper is to demonstrate by means of experimental data that the proposed device is continuously provided with Tension, so that it can send regular data over the years.

This paper presents a hardware architecture for the QR decomposition (QRD) of a complex-valued matrix based on Modified Gram-Schmidt (MGS) algorithm. A high throughput iterative-pipelined design is implemented, which achieves similar performance of a fully parallel-pipelined design, with a significant reduction in hardware usage. For a fixed-point Field Programmable Gate Array (FPGA) implementation optimized to decompose a 4 × 4 complex-valued matrix, an 18.6% reduction in resources utilization is achieved, compared to the fully parallel-pipelined design. Extending the proposed architecture to decompose larger matrices is straight forward, and in such cases more savings with respect to resources utilization can be attained.

No matter how sophisticated and advanced an organization's security system is, it remains vulnerable due to the human factor. In this paper, we conducted a survey to analyze the patterns used by the faculty, staff, and students when generating passwords at a small sized university. We found that users are not as aware of security requirements and practices as they think. Moreover, the vast majority of users' passwords are breakable within days or shorter. Interestingly, we found that using numbers and uppercase letters is common among users. However, numbers are mostly used at the end of the passwords and uppercase letters are mostly used at the beginning of passwords. The existence of such trends makes it easier for attackers to generate more effective dictionaries. Based on the analysis in this paper, we make recommendations to IT personnel and the general public to harden the security of their passwords.

This paper focuses on the problem of drunk driver which is represent one of the major reasons for traffic accidents during the last decades. Alcohol negatively affects the drunk driver judgment abilities and driving skills. Many engineering solutions have been proposed to reduce the consequences of drunk driving. However, most of these solutions were based on a certain type of control units or though computerized protection systems including wirelessly monitoring facilities. This resulted in having systems with demerits of complexity, high cost and slow response in the case of remote monitoring and remote decision making. These solutions were mainly dependendent on one type of controlling unit as well. To avoid all the above mentioned disadvantages, this paper introduces a simple, cheap and highly responsive design. The proposed design is based on discrete electronic components with processing and decision made locally and does not involve wireless transmission to guarantee the required fast response.
