SURVEY : Reputation and Trust Management in VANETs
Jitendra Singh Sengar 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.1
This paper concerns reputation and trust computation in vehicular ad hoc networks (VANETs). Various survey and implemented work has been studied and analyzed to form a new survey on trust model to VANET. In this survey it is observed that there are lot of new techniques are possible to form a new trust model in VANET to provide better security with trust concern over the entire environment of trust management in VANET. Trust management in VANET (TMV) is one well know concept and basic need to maintain a reliable secure faith full VANET on which node may believe through their close eye and could drive for safe journey with ultimate faith.

Enhanced Artificial Neural Network Approach to Identify Specific Binary Pattern
Jitendra Singh Sengar 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.6
The main focus of this paper is to design a Artificial Neural Network Modal to identify specific binary pattern. This pattern will work at binary level to recognize that the received data is authentic at low level, through this work we are able to design a specific binary pattern and it would apply directly to the input layer to check accuracy in data at binary mean at low level. In this paper we have four bit data and user may arrange it in his own specific pattern, then ANN Modal will train for the given pattern then it will apply to check the pattern is found and data is authentic.
Review : Ad-Hoc Cloud Architecture & Modern Cryptography
Jitendra Singh Sengar,Richa Sharma 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.6
This paper is showing the review study on cloud architecture that uses donation based resources in a network & helps multiple organizations to collaborate and yet compete with each other. The resources are utilized non intrusively. Organizations collaborate to create a Data-centre, that doesn’t harm their existence or profitability. At the same time, these organizations can compete by spreading to those locations where they carry certain edge over theirs. An ad-hoc cloud in heterogeneous environment helps to venture into remote areas. To achieve this some, ad-hoc cloud architecture is proposed along with issues and strategies. This is being elaborated in this paper with some effective sense.
Review : A Survey on Brain Tumor Extraction from MRI
Jitendra Singh Sengar,Priyanka Chanderiya 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.6
It is survey over various approaches applied on brain tumor extraction & detection from magnetic resonance image (MRI). Some of them are completely elaborated below with their strength & weaknesses. Magnetic resonance brain image are segmented & synthetically colored to represent original data through modified fuzzy c-means algorithm, supervised computational neural network approach (SCNNA), knowledge based technique (KBT), fractal-based brain tumor detection (FBTD), automatic segmentation of brain tumor (ASBT).
Two Segment Approach to Find Tumor Affected Area from Brain MRI
Jitendra Singh Sengar 보안공학연구지원센터 2016 International Journal of Bio-Science and Bio-Techn Vol.8 No.3
Two region graph cut image partitioning after mapping entire image of brain in brain MRI. It is seen that piecewise constant model of the graph cut formulation becomes applicable when the image data is transformed by a main function. The proposed function contains data term to evaluate the deviation of the transformed data within two segmentation region, from the piecewise constant model, and a smoothness boundary preserving regularization term. Using a common function, energy minimization typically consists of iterating image partitioning by graph cut iterations and evaluations of region parameters via fixed point computation. The method results in good segmentations and runs faster the graph cut methods. The segmentation of MRI image is challenging due to the high diversity in appearance of tissue among the patient. An automatic interactive brain MRI image segmentation system with the ability to adjust operator control is achieved through this method.

This paper presents a novel shunt radio frequency microelectromechanical system switch on a quartz substrate with stiff ribs around the membrane. The buckling effects in the switch membrane and stiction problem are the primary concerns with RF MEMS switches. These effects can be reduced by the proposed design approach due to the stiffness of the ribs around the membrane. A lower mass of the beam and a reduction in the squeeze film damping is achieved due to the slots and holes in the membrane, which further aid in attaining high switching speeds. The proposed switch is optimized to operate in the k-band, which results in a high isolation of -40 dB and low insertion loss of -0.047 dB at 21 GHz, with a low actuation voltage of only 14.6 V needed for the operation the switch. The membrane does not bend with this membrane design approach. Finite element modeling is used to analyze the stress and pull-in voltage.

This paper proposes a novel RF MEMS dc-contact switch with stiff membrane on a quartz substrate. The uniqueness of this work lies in the utilization of a seesaw mechanism to restore the movable part to its rest position. The switching action is done by using separate pull-down and pull-up electrodes, and hence operation of the switch does not rely on the elastic recovery force of the membrane. One of the main problems faced by electrostatically actuated MEMS switches is the high operational voltages, which results from bending of the membrane, due to internal stress gradient. This is resolved by using a stiff and thick membrane. This membrane consists of flexible meanders, for easy movement between the two states. The device operates with an actuation voltage of 6.43 V, an insertion loss of -0.047 dB and isolation of -51.82 dB at 2 GHz.
