Agilla is the most common mobile agent middleware to facilitate adaptive applications in WSN. But due to lack of bandwidth and energy level in agilla, it is restricted to local tuples. This article presents eagilla, a middleware to support remote level multicasting wireless sensor networks. Eagilla organizes multicasting communication in different tuples, integrating mobile agents to the network for sensing data and to regulate the data to organize global communication. Eagilla model comes up with a hybrid multi-layered architecture to reduce the complexity and to support interoperability, heterogeneity in WSN. Eagilla provides non-functional requirements such as Qos, scalability, flexibility and reliability. The effectiveness of eagilla middleware is proved by conducting experiments in a professional environment. © 2017 Faculty of Engineering, Alexandria University.

Day by day the quantum of data has been increasing not only in terms of user generated content in social media but also outside the social media, due to which the data has gone from scarce to superabundant that conveys new advantages to users. This explosion of data has made it difficult to handle and analyze huge datasets. Therefore, the techniques of Data Mining assist in exploring and analyzing enormous datasets and helps in discovering meaningful patterns. Clustering is one such task of Data Mining that gathers all the data and partitions it into various groups taking into account their similarity or closeness measure. Clustering in the field of Social Science is used in identification, analysis and detection of various crime patterns. This paper proposes the Modified k-means clustering technique which is applied on the fictitious crime data in order to identify various crime patterns or trends and make a variety of predictions from the analysis of different crime patterns. © Springer Nature Singapore Pte Ltd. 2018.

In this paper, we consider the sensing methods based on the known noise level in cognitive radio (CR) networks under multi antenna systems and compare with the unknown noise level detection methods. The analysis is focused on energy detection (ED) and maximum eigenvalue based methods that require the knowledge of noise level. Threshold and detection performance of the maximum eigenvalue based method are expressed by closed analytical formulas. Random matrix theory is used to derive the expressions for threshold and probability of detection. The performance comparison of different sensing methods is provided through simulation analysis. Simulation results provide performance of various sensing methods for wireless microphone signals and independent and identically distributed (iid) signals. © 2013 IEEE.

In this study, the authors consider the problem of signal detection in cognitive radio under the cases of known and unknown noise levels. The analysis is focused on maximum eigenvalue-based method which requires the knowledge of noise variance and the ratio of maximum eigenvalue to the trace of covariance matrix. The analytical formulas are derived for threshold calculation and probability of detection for the considered methods. Performance of the considered methods is measured through simulation analysis. The performance comparison between the considered methods and other existing methods is provided. Simulations based on independent and identically distributed signals and wireless microphone signals are presented to verify the various sensing methods. © The Institution of Engineering and Technology 2013.

A Pulse Width Modulation (PWM) Voltage Source Inverter (VSI) fed induction motor drive has superior dynamic characteristics than sine wave driven induction motor. But it has a problem with induced bearing voltage and high frequency bearing current that flows through bearings due to parasitic capacitive coupling that results in premature bearing failure. In many industrial applications the PWM inverters and motors must be at separate locations thus requiring long motor cable, which contributes over voltage and higher common mode voltage at the motor terminal due to voltage reflection phenomenon. Higher common mode voltage results in higher induced shaft voltage and bearing currents. This paper presents simulation and analysis of influence of motor cable length on the magnitude of common mode voltage, bearing voltage and bearing current in two level and three level diode clamped multilevel inverter fed induction motor drive. The dv/dt of common mode voltage and bearing voltage also presented. Simulation is carried out using MATLAB/simulink. © 2015 IEEE.

The Cadmium oxide doped nanocrystalline polyaniline (CdO/PANI) composite was prepared with various weight percentages of CdO by in situ polymerization method using aniline, ammonium persulfate and CdO as starting materials. The CdO/PANI composite was characterized by X-ray diffractometer and FTIR techniques. The SEM micrograph of the pure polyaniline shows irregular shaped granules of size ranging from 60-80 nm and that of CdO/PANI composites show granules of 0.60-0.65 μm in size. The temperature dependent conductivity measurement shows the thermally activated exponential behavior of CdO/PANI composites. The selectivity is found to be maximum for LPG and moderate for CO 2 and ethanol. It is also seen that around 400 PPM v concentration of LPG, sensitivity is 75% for 50 wt% of CdO/PANI composites.

Distillery spent wash is the unwanted residual liquid waste generated during alcohol production and pollution caused by it is one of the most critical environmental issue. Distillery spent wash is one of the recalcitrant wastes having extremely high Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Suspended Solids (SS), inorganic solids, color and low in pH. Wastewater collection, storage, treatment and management are of prime importance towards environmental pollution prevention and control. In this concern, Microbial Fuel Cell (MFC) and Rotating Biological Contactor (RBC) were fabricated and further used to treat distillery spent wash. The present study was carried out at ambient environmental conditions. Different feed concentrations of 1,100 mg COD/L to 10,100 mg COD/L was fed to MFC which treated spent wash anaerobically. As the feed concentration increased the percentage reduction of COD, BOD and Dissolved Solids (DS) increased initially up to 6,100 mg COD/L and further reduction in the removal efficiencies were observed. The highest percentage of COD, BOD and DS removal were 64, 61. 2 and 44. 8 % respectively at 6,100 mg COD/L and was considered as optimal effluent. The average current (0. 27 mA) and power density (18. 35 mW/m2) values also proved to be higher at the feed concentration of 6,100 mg/L COD. This optimal effluent was treated further aerobically in RBC and obtained 84 % COD, 81 % BOD and 46. 4 % DS removal. Hence MFC and RBC can be adopted to treat spent wash in an effective manner. © 2013 Society for Sugar Research & Promotion.
