Introduction Randomized Optimization involves a collection of optimization techniques allowing the computation of global minima in otherwise non-straightforward functions. Making these algorithms unique are tweaks which invoke randomness to expand the search space, preventing their halting when finding local minima. In this paper, we will discuss four common randomized optimization algorithms: randomized hill climbing, simulated … Read more

1: General Context Industrial control systems which are also known as ICS are generally used for controlling the various Industrial processes. These systems include many complex connections and the architecture for running the production in the Industry. These generally include Programmable Logic Controllers (PLC), Supervisory Control and Data Acquisition (SCADA) along with distributed control systems … Read more

This introduction will prepare and inform, once read, there should be a better understanding of the project. It will also include the aims and objectives of the project, which will be discussed to provide clarity. The aim of this project was to create an app that locates coffee shops for a user that are in … Read more

Initially known as MSN Messenger since its inception in 1999 and Windows Live Messenger from 2005, which was the king of instant messaging services closed its meeting on 31 October 2014. Year and a half later and the wisdom they have Mondays when you see the results of the pools, one wonders why. MSN Messenger … Read more

Investigative Question Is it possible to increase the speed of a wireless internet connection by using satellite-based concepts such as radio wave reflection to focus the signal in a certain direction? If possible, by what percentage will the signal be increased? Is it possible to increase the speed of a wireless connection by reflecting concentrated … Read more

ABSTRACT MANETs are deployed in adversarial environment it is important to provide a security based on onion routing mechanism a security is provide by authenticating the route request packet to satisfy unidentifiability and unlinkability, maximizing the throughput. In order to reduce the delay and to evaluate energy consumption the AASR protocol is combined with trust … Read more

Abstract: This paper presents a survey of fragile watermarking schemes for image authentication proposed in recent times. The limited embedding capacity and extent of tampering are some of the important issues among other issues that drive the research in this area. Therefore we have presented in this survey the gist of the components of the … Read more

ABSTRACT: The main objective of my project is to find the edges of the grayscale image effectively with less computational complexity and also to reduce the thickness of the image edges. Edge of the image is one of the most fundamental and significant features. The classical studying of computer vision and image processing field is … Read more

Reasons for choice of language: Organizational Policy: “BAC IT” is an IT software development firm and its organizational policy confirms total intolerance to software piracy. Which is why the use of java language as it is free for use. It legalizes the software development process and also dramatically reduces the cost of ownership of the … Read more

I. Summary of Proposed project Multi Input Multi Output (MIMO) strategies accomplish the similar Bit Error Rate i.e., higher throughput (point-point communication) by permitting nodes to sending and receiving information combined with lower power (individually, for the same power) . Multi input multi output (MIMO) frameworks are studied very thoroughly in recent years because of … Read more

3. OVERVIEW AND EXPLANATION 3.1 ONION ROUTING It is a mechanism to provide private communications over a public network in which the sender and the receiver nodes communicate with each other anonymously by means of some intermediate nodes called onion routers. It relies on public key cryptography. The source node sets up the core of … Read more

Introduction Since time immemorial security has been inevitable for the safe and peaceful existence of mankind. The need for security is an essential and fundamental need to for survival. Security cut across all areas of life from providing security for life to providing security for properties which are non-living things. The need for security also … Read more

MVC MVC is an architectural pattern that separates an application into three main logical components: the model, the view and the controller. Model component correspond to all the data-related logic that the user works with. It also represents the data that is being transferred between the View and Controller components. View component is used for … Read more

Abstract: Communication in Mobile Ad hoc (MANETS) networks happens without specific infrastructure. This prototype assumes that an arbitrary node will forward traffic flow originating from other nodes readily. Contrariwise, in aggressive surroundings where we discover most uses of ad hoc systems, an always obliging and obedient behavior on behalf of the other nodes of the … Read more

Abstract This paper investigates Structured Query Language (SQL) Injection from a web security stand point. SQL Injection consists of attackers injecting malicious SQL commands into an application to alter how it interacts with the database. This consists of any statement that creates, reads, updates or deletes data from a database. SQL injection is dangerous because … Read more
