Device Applications of Metal-2D-Materials Interfaces A Short Review

Abstract: The electronic energy band gaps of 2D-materials are known to spread over a wide range from zero in graphene to > 6eV in hexagonal boron nitride (h-BN). Various combinations of such engineered nanomaterials offer a number of novel device applications involving their unique optical, electronic, and thermal properties along with their higher charge carrier mobilities and saturation limited drift velocities. Structurally, these nanomaterials have single or multiple monolayers stuck together, which are not only suitable for flexible electron devices and circuits but also in preparing heterostructures (lateral as well as vertical configurations) that form super lattices with different kinds of band alignments. Such possibilities offer flexible control over the charge carrier transport in these materials via numerous types of exciton formations. Their extra sensitivity towards the presence of atomic, molecular and nanoparticulate species in their vicinity is the most significant aspect of these 2D-materials. This is the reason behind studying them in detail for detecting the presence of extremely low concentrations of the analyte that are not achievable in conventional sensors. For translating the above-said superlative properties of these fast emerging families of 2-D nanomaterials into usable devices and circuits, applying the conventional device fabrication technologies poses a real challenge. The experimental results reported in the context of forming usable interfaces between a metal and 2D-nanomaterial are examined here to assess their current status and future prospects. Their widespread applications are certainly anticipated in the fields like printed micro/nano sensors, large area electronics and printed intelligence with special reference to their emerging usages in Internet of Things (IoT) in the near future.

Regression test selection for object oriented systems using OPDG and slicing technique

Abstract: Regression testing is a selective retesting of software whenever software gets modified or some new functionality is added to it In this paper a regression test case selection technique is proposed This technique is based on identification of affected paths, affected functions and dynamic slicing which can be used to reduce the number of test cases for regression testing This paper considers all three cases of modification to object oriented programs The proposed approach is evaluated by showing the reduction in total number of test cases to be selected For each program to be tested, this approach focuses on finding the affected paths, affected functions and on computing the dynamic slice of modified variables In addition this approach is also open to combine a variety of available information for selection of test cases For analysis it is applied to the software module in C++

An efficient hybrid security mechanism based on chaos and improved BPCS

Abstract: Commonly used security mechanisms such as cryptography and steganography suffer from weaknesses when used in a standalone manner. Extra efforts in the form of additional permutations/diffusions etc. result in higher ciphering/deciphering time complexity. Thus, there is a requirement for a security mechanism(s) which can provide adequate security without putting a considerable burden on ciphering/deciphering time complexity. This paper is an effort in this direction. The paper proposes a hybrid mechanism that employs chaotic based encryption scheme to encrypt data and an improved Bit-Plane Complexity Segmentation Steganography algorithm to embed the data. The proposed mechanism uses two new complexity measures to differentiate between noisy regions and simple ones appropriately. The scheme was implemented in MATLAB, and the simulation results show that the proposed mechanism has high embedding capacity, high security with a moderate decrease in PSNR value and is computationally fast.

FANET routing protocols: Review

Abstract: FANETs is most evolved research area in today's time it makes use of multi-UAV. Use of UAVs is increasing day by day due to the advancement of sensors, processor, and applications. FANETs is mostly used in the undeployed area such as flood, Drought and most importantly in military reason. The main challenge of FANETs is routing of these multiple UAVs due to high speed which required highly dynamic routing protocols. In this paper, we tried to study already proposed routing protocols.

Developing the weighted ISM-MICMAC framework for process design stage of production system life cycle

Abstract: The main purpose of this paper is to develop a framework for the process design stage of production system life cycle (PSLC) using weighted interpretive structural modelling (ISM) and MICMAC analysis. In the present study, various quality enabled factors (QEFs) of process design stage has been identified through the extensive literature analysis and opinions of industrial and academic experts. In order to validate the identified QEFs, a questionnaire survey has been utilised. Then, QEFs are analysed by using ISM approach in order to develop the relationship among the considered QEFs. Afterwards, Matriced Impacts Croises Multiplication Appliqueeaun Classement (MICMAC) analysis is used to identify the driving and dependence power of QEFs. Lastly, a method of effectiveness index (EI) has been used for identifying the key areas of process design stage of PSLC. This index can be effectively utilised by the manufacturing organisations to benchmark their process design phase through effectively utilising the QEFs reported in this work.
