 Abstract

In the daily scenario, people facing many illnesses due to unwanted pollution of air, smut. Nowadays most of the people working in the industries, organizations are unaware of dust levels and they also not even know about toxic gas which is presented in the air so we are implementing this idea with the help of internet of things technology used to find dust levels and toxic gases in air it is used to help people to know about the environment polluted or not. The premises of this research idea are to prevent people affected by allergy in cause of dust present in the environment. Measuring air quality by finding its density was an existing idea. We are using dust sensors to find out dust particles presented in the air. Moreover we are also finding the toxic substances presented in the air using gas sensor and also it measures temperature and humidity presented in the air. In addition to that our schema is about sending information to people about dust alert present in the workplaces. With the help of the message, management can pass it to workers so that they can clean that area

With fast development over generations, encryption is one of the most trusted approaches for data protection and privacy. Data encryption strategies are meticulously applied in such a way that the original information is recovered easily using a key, referred to as decryption. Encryption can be implemented using techniques like substitution, permutation or by some mathematical operations. By applying any one of these, a cipher text thus generated goes beyond human comprehension and readability. This paper, provides a basic overview of five different substitution and transposition encryption techniques and an analysis of these algorithms based on the effectiveness of each algorithm with regard to the efficiency parameters like encryption time, decryption time, memory utilization and the avalanche effect. All the algorithms are tested using Java 2 Platform Standard Edition Development Kit 5.0.

 Abstract

Aluminum wheels should not fail during service. Their strength and fatigue life are critical. In order to reduce costs, design for light-weight and limited-life is increasingly being used for all vehicle components. In the actual product development, the rotary fatigue test is used to detect the strength and fatigue life of the wheel. Therefore, a reliable design and test procedure is required to guarantee the service strength under operational conditions and full functioning of the wheel. Loads generated during the assembly may cause significant levels of stress in components.

 Abstract

Electronic commerce is generally thought as simply buying and selling of goods and services using the internet. But actually e-commerce involves much more than electronically mediated transactions between organizations and customers. People using internet must understand the risk of using it. The security safeguards ensured are sometimes not adequate to protect the data or private information. Many people are getting victim of frauds. Credit card and identity theft are common online frauds now days. There is a need of controlling, monitoring, auditing and taking actions so we can attain highest level of security. No matter how secure the system is but a malicious insider can create blunders so e-commerce is slowly focus on internal security and started training and orientation program to make people aware of security concerns.

 Abstract

The public sector became a major instrument of planned economic development and was viewed as its prime mover in several countries including India. Public sector is a very comprehensive term encompassing a vast array of activities undertaken through public funding from resources raised mainly through fiscal efforts. In India public enterprises consists of central public enterprises and state level public enterprises. The major sources of financing of public enterprises are equity and debt financing. Generally, financing decisions are often referred as capital structure decisions. The objective of the study is first, to analyse capital structure of selected state level public enterprises with the help of selected ratios, second analyses the influence of capital structure on the over all operating result of the state level public enterprises and compare the impact of new economic policy in the financial health of the Modern Manufacturing Public Enterprises (MMPEs) of Kerala. The analysis reveals that the financial health of the modern manufacturing state level public enterprises in Kerala has improved after the implementation of the new economic policy.

 Abstract

A per the thought of a great scholar of Hyderabad Narendhra Luther Muhammad Quil Qutb Shah built the beautiful city of Hyderabad as a 'replica of heaven on earth'. It was plundered in 1687 by the Mughal forces led by Aurangzeb. After a long period of neglect it rose to be the capital of the expansive Deccan province. The city witnessed phenomenal expansion under Asaf Jah I, and also the dissipation of his legacy. The author acknowledges the most unique feature of this city--the continuance of its cosmopolitan character in the face of communal pressures. He attributes this amalgam of Hindu and Muslim cultures to the mixed 'parentage'--Hind and Muslim--of its rulers. As per the title related Hyderabad is most popular for the unique on Tourist places i.e; Monuments like Golkonda Fort, Charminar and Plaknama etc; Bazaars like Lad Bazar, Kabutarkhana and Cappal Bazaar etc; Museums like Khazana Building Museum, Salarjung Museum and H.E.H Nizam Museum etc; as per the research paper shows on the related topic mainly the museums are the most important; why because how they are leaved, those life style extra ; based on present research can move for educate and every one can get knowledge.

 Abstract

Earlier some of the authors have shown the nature and occurrence of the singularities in non spherical gravitational collapse of strange quark matter and Hussain space time. In the previous issues it was also shown that the naked singularities are formed. In the present work we explore the comparative study about the nature of naked singularities occurred in between both the space times. Implication of the same initial data to the non spherical gravitational collapse of strange quark matter and Hussain space times has been discussed.

 Abstract

Let G be a finite and simple graph with the vertex set V = V (G) and edge set E = E(G). If v is a vertex of a graph G, the open k-neighborhood of v, denoted by N_k(v) and N_k [v] = N_k (v) ? {v} is the closed k-neighborhood of v. A function f? V (G) ? {-1,+1} is a k-distance non-negative signed dominating function (k-DNNSDF) of a graph G, if for every vertex v ? V, f(N_k [v]) = ?_(u?N_k [v])??f(u)?0?. The k-distance non-negative signed domination number (k-DNNSDN) of a graph G equals the minimum weight of a k-DNNSDF of G, denoted by ?_(k,s)^NN (G). This paper contains some properties of k-DNNSDN in graphs and some families of graphs such as cycles, paths, Complement of cycles, Complete graphs, Wheel graphs and Friendship graphs which admit 2-DNNSDF.

 Abstract

In recent days Cyber attacks have become common threat which is leading to exploit data confidentiality. Spoofing is a common technique which is used by the attackers to make themself unidentified and probe towards phishing the data from target machines. So to make the data not influenced to phishing and the nodes in the network are not subjecting to spoofing we use a mechanism called pilot signal which is used with Channel state indicator. When we like to send data from the source to receiver we use a mechanism called pilot signal which is used like a strobe to the node in the network and estimates the channel state having the genuine internet protocol address. We maintain uplink and downlink paths for the nodes. We set frequency energies to the node at the time of adding it to the network, these frequencies are used to send and receive the signals throughout the network. By using CSI in the downlink and uplink paths the difference in the frequency is calculated to detect a spoofing event over a node if the received parameters are in un order to the standard frequency which is aligned earlier we treat it as detection of spoofing attack. The detection probability is evaluated based on the derived parameters of CSI from a node at a given requirement on the less probability of false alarming. The achievable secrecy rate is utilized to measure the security level of the data transmission. Our analysis shows that even without any pre-assumed knowledge of eavesdropper, the proposed scheme is still able to achieve the maximal secrecy rate in certain cases. our scheme could achieve a high detection probability as well as secure transmission.
