A cancer diagnosis by using the DNA microarray data faces many challenges the most serious one being the presence of thousands of genes and only several dozens of patient's samples. The classification of different tumor types is of great importance in cancer diagnosis and drug discovery. Although cancer classification has improved over the past 30 years, there has been no general approach for identifying new cancer classes (class discovery)or for assigning tumors to known classes (class prediction). The recent advent of DNA microarray technique has made simultaneous monitoring of thousands of gene expressions possible. The results demonstrate the feasibility of cancer classification based solely on gene expression monitoring and suggest a general strategy for discovering and predicting cancer classes for other types of cancer, independent of previous biological knowledge.

Cancer classification is one of the major research areas in the medical fields. The primary objective is to propose efficient cancer classification techniques which provide reliable and significant classification accuracy. To achieve this primary research goal is to find the smallest set of genes that can ensure better performance in classification using machine learning algorithms. Gene expression of microarray data requires the selection of subsets of relevant genes in order to achieve good classification. Modified Extreme Learning Machine (MELM) is used for direct multicategory classification problems in the cancer diagnosis area. Modified ELM avoids problems like local minima, improper learning rate and overfitting commonly faced by iterative learning methods and completes the training very fast. Experimental result shows that the Modified Extreme Learning Machine (MELM) classifier is used for increasing the classification accuracy over ELM by using three benchmarks microarray datasets for cancer diagnosis namely, Leukemia, Lymphoma and SRBCT.

Automotive theft has been a persisting problem around the world and greater challenges come from professional thieves. In this paper, we present an automotive security system which effectively prevents the stealing of key auto systems for re-sellingby introducing three layers of security features written in the form of firmware and embedded on the Electronic Control Units(ECUs). First we design a new Innovative car key, the car key transfers a random data each and every time the car is unlocked. The transaction of password from key to car is known only to these devices and any intermittent unit cannot diagnose the transaction as each and every time the data is changing. Secondly the image section has been proposed for security system in car. The face recognition and comparison is done in this section. Thirdlya Controller Area Network(CAN) bus based authentication system has been introduced to avoid the dismantling of car parts and reuse in some other vehicle, wherein the car engine gets started only in case if the car part belongs to the car. It has showed in practice that compared with the traditional auto guard system, this system could not only stop car theft singly, but also improve the security and reliability.Keywords

This paper presents the method for selecting the power system stabilizer (PSS) parameters. Design of local output feedback power system stabilizer using local signal of the generator (e.g. speed or power) is formulated as a decentralized modal control (DMC) problem. Exact model reduction based on modal control theory is proposed to make the determination of PSS parameters highly efficient. Results obtained from the coordinated tuning of the parameters of power system stabilizers equipped on a SMIB system show that exact assignment of the eigenvalues associated with the poorly damped electromechanical modes can be achieved in a very efficient manner.- Simulation and Modelling of 5-Level Single Phase Z-Source based Cascaded Inverter

Objective: Small-signal modelling is a widespread analysis practice in power electronic converters which is used to fairly accurate the performance of non-linear devices with linear equations. The order of the dc-dc depends on the non-linear elements of the system. As the number of non-linear element of the converter is high, it’s modelling and control becomes extremely complicated. Thus, there is a need for generalization of such converters by small signal modelling. Traditional modelling schemes using the averaging and small-signal linearization procedures are utilised for the advance modelling of the converters. Method: In this work, the purpose of the switching flow graph (SFG) and the Mason’s gain formula aid the solution of the equations. The duty cycle to output and the input to output transfer functions are obtained. Those transfer function can be used for closed loop examination. Findings: Open loop analysis of the converter is done and the outcomes are verified through simulation. Theoretical and simulation results are shown to prove the accuracy of the developed small signal models. The derived topology is unstable in open loop condition. A prototype is developed to validate the performance of the proposed topology. Improvement: Closed loop analysis can be carried out with any type of controller.Keywords

Blockchain technology has revolutionized the way in which financial transactions are conducted. It has made possible secure financial management and digital transaction systems that are faster, more secure, and more reliable than traditional payment methods. Blockchain technology offers increased efficiency, trustworthiness and transparency to its users. The Blockchain works by creating a shared, distributed ledger of transactions. Each transaction is cryptographically secure and immutable, and all participating nodes have identical copies of the ledger. This ensures that transactions are traceable and secure, eliminating traditional problems such as double spending or fraudulent activities. Through the integration of Blockchain, the system provides transparency, prevents fraud, and ensures accountability. The research focuses on optimizing performance by reducing processing times and transaction costs, while maintaining scalability and flexibility. Additionally, the system facilitates auditing and compliance processes, while promoting financial inclusion by providing access to unbanked individuals. The proposed system’s contributions lie in its novel approach to secure financial management, utilizing Blockchain’s features to address the challenges of modern digital transactions.Keywords
