One of the crucial and challenging issue with the use of Wireless Sensor Network (WSN) for monitoring pipelines, detecting and locating leaks is that of energy saving. With the use of real-time acquisition using heterogeneous sensors, communication and innetwork processing, a great level of accuracy in the results can be achieved, but may involve huge energy consumption. In this work, the idea of exploiting 3 different approaches for energy conservation in WSN is presented for water pipelines monitoring namely schemes based on Duty-Cycling and Data-Driven approaches for energy saving, and Least Squares Estimation are presented for reducing communication, sensing and processing energies, when noisy pressure sensors along a straight pipeline are used for finding the location of a leak. Simulation results are shown for localization of small and large leaks for different numbers of sensors that result in various levels of accuracies and energy consumption, which shed some light on the tradeoff that can be achieved in saving energy and attaining good accuracy.

The transformation of a city into a smart city starts in urban quarters. Information and communication technology is a key factor for the implementation of smart solutions for a higher quality of Life in urban spaces. International Standards can be a solution for these future challenges. To link the important phenomena "smart city, smart grid, electric vehicle" the paper on the one hand suggests a methodical approach of the communication design between these complex systems and on the other hand considers their influence on the functional behavior of the power net.

This paper presents a simulation study using different control strategies to control the position of robot arm DC motor. Fixed field DC motor mathematical model is applied using certain parameters settings. A state feedback pole placement, Fuzzy Logic, Multi-Layer Perceptron (MLP) Neural Network, and the conventional PID control theories have been applied successfully. Matlab Simulink work space is used in the simulation. Almost the same controlled output responses are obtained with a different transient responses speed.

Underwater vehicles have developed greatly to the point that allowed their use in a variety of applications. However, using this kind of vehicles for in-service oil tank inspection is not yet advanced enough. As part of an effort to design a new class of underwater vehicles suitable for inspection, the present work ascertained requirements devoted to each component of those vehicles. A detailed design process was introduced and the main parts of the vehicle are described with emphasis on its related constraints. Finally, a control navigation strategy is proposed so that the vehicle will incorporate six degrees of freedom.

The serious threat of global warming on earth made it necessary to look for alternative sources of energy. In fact, the seek for clean and cheap energy is subject of several research investigations nowadays, and the invention of solar cells was one of the breakthrough towards clean energy alternatives. Unfortunately, the solar cells dominating the market are all made of inorganic materials requiring expensive and complicated manufacturing processes and have limited applications basically to the rooftops. One of the promising alternatives to inorganic solar cells is the organic ones. In this paper, a thorough review on the organic solar cells is elaborated.

Modern industrial networks and field-buses are designed to provide a tough and efficient communication between all connected peers. Complex data stream modifications like encryption or compression are often omitted to ensure functionality and compatibility. The DNSec project aims to add these features while retaining typical characteristics of dynamic industrial networks.

We consider a two-wheeled single axle vehicle freely moving on the horizontal plane. This system is underactuated, nonholonomic and unstable. In order to achieve a simple control structure, the system is modeled on two levels: a nonholonomic kinematic model covering the motion of the axles midpoint and a holonomic kinetic model reflecting the (unstable) dynamics of the 3D multibody system. The kinematic model can be controlled via dynamic extension and exact feedback linearization while the multibody system is stabilized by a linear static state feedback. Both models are linked by the velocities of the wheels. The unavoidable lack of controllability for vanishing velocity is also addressed.

This paper investigates the problem of fault detection for discrete linear systems subjected to unknown disturbances, actuator and sensor faults. A bank of Augmented Robust Three stage Kalman filters is adapted to estimate both the state and the fault as well as to generate the residuals. Besides, this paper presents the evaluation of the residuals with Bayes test of binary hypothesis test for fault detection to adaptive threshold compared with fixed threshold. This test allow the detection of low magnitude faults as fast as possible with a minimum risk of errors, the increase of detection probability and the reduction of false alarm probability.

Although the research made in the field of indoor localization based on wireless sensor networks (WSN) has shown encouraging and sometimes adequate results in terms of position estimation accuracy, raising the network longevity is still a challenging issue especially when the used sensor nodes are battery-powered and their energy capacity is very limited. In this paper we present an energy efficient approach for indoor localization purpose that is based on optimizing the activity periods of the sensor nodes during the indoor localization process.

In this work, a passive rectifier circuit is presented, which is operating at 868 MHz. It allows energy harvesting from low power RF waves with a high efficiency. It consists of a novel multiplier circuit design and high quality components to reduce parasitic effects, losses and reaches a low startup voltage. Using lower capacitor rises up the switching speed of the whole circuit. An inductor L serves to store energy in a magnetic field during the negative cycle wave and returns it during the positive one. A low pass filter is arranged in cascade with the rectifier circuit to reduce ripple at high frequencies and to get a stable DC signal. A 50 kΩ load is added at the output to measure the output power and to visualize the behavior of the whole circuit. Simulation results show an outstanding potential of this RF-DC converter witch has a relative high sensitivity beginning with -40 dBm.
