The material system 0.92 Bi0.5Na0.5TiO3-0.08BaTiO3 are an excellent candidate of lead free ceramics which were prepared by conventional solid-state sintering method. In this study, sintering was carried out 1000° C, 1050 ° C, 1100 ° C temperature with one fixed composition (x=0.08). X-ray diffraction pattern showed the co-relation of rombohedral & tetragonal phases was indicative of the MPB around x=0.08 & BNT-BT crystallization occurred at 900 ° C, which was ensured by peak splitting 20~46.5° of (002) plane. The density of BNT-BT was increased with rising temperature and maximum densities were obtained at 1100° C temperature. Microstructure of the samples were examined by field emission scanning electron microscopy (FESEM), which ensured that the grain size tended to increase with temperature. The MPB composition, sintered for 2h at 1100 ° C, signified better properties: larger grain size ~687.81 nm. The dielectric constants ($varepsilon _{mathbf{r}}$) were measured, which availed that with increasing sintering temperature, $varepsilon_{mathbf{r}}$ values were also increased and maximum dielectric constant 1046.73 was attained at 1100 ° C for x=0.08. Thus, BNT-BT ceramics suggested about the usefulness of these systems for the capacitor, sensor & most importantly energy storage applications, respectively.

The aim of this study is to build a classifier for predicting a disease existence by learning a least conventional set of features extracted from the clinical dataset. Rough set, indiscernibility relation method along with a feedforward neural network is applied and divided the whole process into two parts. At first part, the rough set method is considered as a reduction of features and selected as subset of attributes. In the next part, classification via feedforward artificial neural network is applied to the selected reduction on the dataset. Obtaining datasets of skin cancer disease from the Engineering in Medicine and Biology Society (EMBC) has been used to test the classifier. Our proposed method obtained 95% accuracy for melanoma skin cancer detection. In this regard, this (ANN) model is proposed intended for detecting automatically the cancer patients at a primary stage. Finally, our proposed model is working improved as opposed to some other conventional model (for example RF and SVM).

Individuals in online social networks seek and share information with other social users having similar topical interests or choices which results in the formation of online social groups or communities. Existing approaches considered the social users’ interests and structural property of the social network to find online social groups. However, most approaches ignored the degree of intimacy among the users resulting in less interactive social groups. Many business companies require interactive expert consumers for advertising their marketing information. In this paper, we propose a model to discover topic-aware intimate online social groups in which group members are highly interactive with others in the group. The performance of our proposed approach is demonstrated by conducting experiments on dataset.

Vehicular ad hoc network (VANET) has attracted more attention for providing safe and efficient traffic management in the modern roads. Performance of the VANET depends on proper routing protocol, mobility management, and efficient inter-vehicular communications. To ensure the optimal data forwarding and energy efficiency in VANET, a suitable network hierarchy is required. In this paper, we propose a new optical network-based clustering hierarchy (ONCH) to improve the quality of services of the VANET. In the proposed scheme, the road side units (RSUs) of a VANET will be divided into several small groups called clusters. In each cluster, an RSU will act as gateway node and each gateway node will be connected to the WiMAX base station through optical fiber. We have analyzed the performance of the proposed ONCH scheme by numerical simulations. The simulated results prove that the ONCH scheme of VANET provides higher energy efficiency than the conventional wireless network-based clustering hierarchy (WNCH) scheme of VANET.

Falls are a dangerous problem for people of all ages. Thus, accurate falls detection with minimized false alarms is very important. This study aims to detect falls and activities of daily living (ADLs) using acceleration data and to introduce an effective feature selection criterion to reduce the false positive rate of the falls detection systems. The falls detection system in this study consists of three stages. At the first stage, we have harnessed some feature extraction techniques to have discriminative features from the acceleration data. Then we have used feature selection criterions to select effective features in the detection task. At the last stage, we used Support Vector Machine (SVM) to classify the selected features in falls and ADLs. We have used raw acceleration data and extracted all the features. Then we selected features based on the Minimum Redundancy Maximum Relevance (MRMR) criterion and Double Input Symmetrical Relevance (DISR) in the fall detection experiment. We have found that the DISR feature selection criterion is more effective in acceleration based fall detection system. The results show 100% classification accuracy and zero false positive rates in fall detection for the DISR based selected features.

In this paper we propose a very highly sensitive photonic crystal fiber (PCF) based refractive index (RI) sensor with a Nano film of gold which is externally coated. To avoid any reflection of radiation power, the utmost layer is circled with perfect match layer (PML). Finite element method (FEM) based numerical outcome shows that the proposed sensor has a maximum amplitude sensitivity of1052 per refractive index unit $(mathrm{R}mathrm{I}mathrm{U}^{-1})$ and maximum wavelength sensitivity of 24,000 nanometer per refractive index (nm/RIU) in the basis of y polarization mode with the variation of wide refractive index range from 1.33 to 1.42. Therefore, this proposed sensor can be implemented for unknown analyte and chemical detection.

When two transmission lines with different imbalance factor are connected, mode conversion occurs at that interface point. The aim of this paper is to suppress mode conversion by improving the shielding of Ethernet cable connector or RJ45 connector of male and female types. By focusing on it, we improved the shielding of the connector by filling gaps at the edge of the connector shield with copper foil tape and the gap between the underside of the female type connector and the printed circuit board, with solder. In this way, the improved shielding around the connector makes the imbalance factor of the connector section close to that of the cable section, and results in the suppression of mode conversion. Based on this idea, it was experimentally confirmed that the shield-improved male type connector shows better reduction of mode conversion than the shield-improved female type connector. Moreover, more reduction in mode conversion was observed when implement the improved shielding of male and female type connectors together.

The thermal conductivity of Graphene Nanoribbon (GNR) of size 10nm×2nm is investigated in our study for different interatomic potentials by varying the temperature in the range of 200K to 600 K. In our study, we have considered Tersoff-2010, REBO, AIREBO and Tersoff-original potentials that are widely used to model the interatomic forces present in any C-C system. The highest room temperature (RT) average thermal conductivity of GNR reported in our study using tersoff2010 potential is 1865 $Wm^{-1}K^{-1}$. To validate our simulated results, we have also calculated the phonon density of states (PDOS) for all the potentials at RT. Our calculated PDOS for Tersoff-2010 potential shows many peaks at different frequencies which mostly resembles the experimental results. Therefore, our study strengthens the application of Tersoff-2010 to model the interatomic potential for any Graphene based system. Moreover, the high thermal conductivity of GNR found in our study for all the potentials suggests the application of GNR in many electronic and optoelectronic devices.

This paper is concerned with the Analysis and Mitigation of Harmonics generated by the Solar system, Semiconductor device, and Power electronics converters. The investigation of harmonics has been carried out for analyzing total Harmonic Distortion (THD%) of the system with and without filters. Then by using harmonics filter or passive filter, the 5th, 7th, 11th, and 13th harmonics are compensated. Then the data and simulation of THD percentage are shown. DC-DC and DC-AC converters create many harmonics. Harmonics are measured line to line in AB, BC, and AC of a 3 phase line. Finally, the Total percentage of THD is come down to 0.72% which is our desired value. So, the main aim is to design a PV solar system and a passive Harmonic filter to mitigate Harmonics from the system.

The main challenge of today's wireless network is the Quality of Service (QoS) of the medium. Now a days, many different types of Ultra High Definition (UHD) video types are introducing and online streaming of these videos are getting much popular to the users for the high quality viewing experience. But the conventional way treats all the video traffic in the same manner which may lead to the unusual delay of the real time streaming of UHD video traffic. Considering dense deployment scenario a new amendment is expecting to be announced called IEEE802.11ax on 2020 by making a big change in Physical layer features which will make faster data transmission in the network than ever. Moreover, in such huge contending situation there must need a suitable medium access control (MAC) protocol which can give priority access to UHD video traffic and can overcome the lagging experience of time critical video traffic. We have investigated this issue and proposed a novel technique to mitigate UHD video traffic scheduling problem.
