This paper presents a new structure to implement compact bandstop filters by employing coupled DGS resonators etched in the ground plane. The proposed bandstop filter consists of symmetrical DGS resonators with a microstrip excitation to obtain a bandstop filter response. By adjusting space S between the two DGS coupled resonators, the bandwith of the bandstop filter can be easily controlled. A bandstop filter is designed, analyzed and implemented on FR4 dielectric substrate to operate at 2GHz. The measured results are in good agreement with simulations.

Simple uniform reduced order model is used to model an RLC interconnect line. Waveform characterization is used to evaluate the accuracy of the adopted models. As compared to RC lines, less than five times the number of sections is sufficient to model RLC lines. Look-up tables are provided to simplify the process of choosing the best interconnect section model to characterize an RLC interconnect line. The tables are shown to be accurate for wide range of relative impedance of the driver, the line, and the load. The tables provide a simple and quick mean to characterize an RLC interconnect which is necessary for performance evaluation in digital circuits. The presented model reduces the simulation time while keeping the simulation accuracy. The simulation time can be reduced by up to 72% with less than 10% reduction in accuracy using the provided tables.

Development of the tracking algorithms used in an infrared seekerhead missile requires the infrared characteristics of the target against which the missile will be directed. Mid-wave infrared recordings of such a target were made at altitude during a flight test. The measurement setup for this test is described, as well as the additional recordings required during data reduction afterwards. An exposition of the general theoretical approach used for the data reduction of infrared image recordings of targets is given and the minimum data required is inferred. The data reduction is then applied to the plume of the target aircraft. The results of the plume data reduction, consisting of mid-wave infrared radiance profiles at different altitudes and the effect of altitude as well as aircraft aspect angle on plume intensity are then presented.

Modern experimental radar systems that are used for advanced research into persistent surveillance and topics such as high range resolution need an ultra wide bandwidth of several hundred megahertz. There is furthermore a requirement for a high Spurious Free Dynamic Range (SFDR). This presents a unique challenge to the designer of the receiver- and exciter system. This paper presents the design challenges and one solution to these challenges.

In this paper we have studied strained structures wells based on GaInAsSb over GaSb substrate. The GaSb substrates allow the mesh accordability with the GaInAsSb solid solution in the range 1.7–3.5 μm. The conduction band and valence discontinuities are evaluated. A Basic source-detector direct transition has been demonstrated at 2–3 μ m. The III-V based GaSb components have many applications in optical fiber links, radar transmissions through atmospheric windows or air detection and spectroscopic analysis of the gases. From this structure it is possible to make semiconductor lasers operating continuously at room temperature, low non-cooled detectors.

Electrical power grid is among the critical infrastructures of a nation. In the past several years, the power grids have experienced several major failures which have caused large financial losses in various countries around the globe. In a close future, the imbalance between the growing demand and the diminishing fossil fuels, aging equipments, and lack of communications are anticipated to negatively impact the operation of the power grids. For this reason, governments and utilities have recently started working on renovating the power grid to meet the power quality and power availability demands of the 21st century. The opportunities that have become available with the advances in Information and Communications Technology (ICT) have paved the way to this modernization. The new grid empowered by ICT is called as the smart grid. The natural extension of the smart grid applications to the consumer premises can be through Wireless Sensor Networks (WSNs) which are able to provide pervasive communications and control capabilities at low cost. WSNs have broad range of applications in the smart grid. In this paper we discuss the application of the WSNs in the home energy management services. We evaluate the performance of WSNs in terms of delivery ratio, delay and Packet Delay Variance (PDV) for varying interarrival times and varying network sizes. We also provide numerical results on the reduced cost, load and carbon emissions by our home energy management application.

Automatic testing of stationarity and detecting of its abrupt change are of primary importance in numerous applications ranging from exploratory data analysis to diagnosis or surveillance. In which case, we are interested in points where the signal stationarity is violated. We consider the problem of how to detect these change-points, which we identify by finding sharp changes in the signal characteristics. Several different methods are considered. Here we suggest a method for detecting and picking these abrupt changes automatically. We divide a record into intervals of equal lengths and check the "local stationarity" between two consecutive intervals by using cross correlation. Because of its ability to accentuate abrupt changes in the signal frequency, it can be effectively employed to detect weak signals in a stationary noise background. In this paper we demonstrate the technique on the problem of detecting and picking P-arrival phase seismic. The intervals have approximately the same characteristics when these include only background noise. But, the similarity breaks abruptly when a seismic signal arrives. This break of similarity makes us possible to detect P-wave arrival. Because the method can detect changes both in frequency and amplitude we can use it on a basic problem in seismic data analysis, which is recognition of weak signals in the presence of ambient noise.

Decision on a strategy for effective predictive Reliability, Availability, Maintainability and Safety (RAMS), by the application of Bayesian networks, while ensuring a better preserving of the operators and installation safety in its entirety. A Bayesian network is an acyclic directed graph where nodes represent discrete random variables value (True, False), and the links influences between the variables or conditional dependencies. Relations between variables are deterministic or probabilistic. In a context of risk management, the causal relationships between different events (cause-effect) that can save any installation dysfunction should be taken into account, integrating the conditional probabilities, based on the opinions of experts' field and on the data mining. Bayesian Networks have become a tool for uncertain reasoning, monitoring tasks such as diagnosis, prediction, and decision making. This makes Bayesian networks a subject of research of artificial intelligence. The processing of data through inference allows us to analyze up-and-down and enrich the basis of feedback through the acquisition of observations (evidence). In this study we present the contribution of Bayesian networks to production and processing of natural gas and an application example will be given for a component (boiler) of the liquefied natural gas complex GL4z industrial facility located in Arzew, western Algeria.
