Adhesion of Fouling Organisms and its Prevention Technique

Biofouling is the undesirable accumulation of microorganisms, plants, algae and animals on submerged structures especially ship hulls. Biofouling also occurs on the surface of living marine organisms. It is also found on membrane systems such as membrane bioreactors and reverse osmosis spiral wound membranes.The application of TBT and other heavy metal-based antifoulants has created another environmental problem.This review article summarizes the adhesion mechanisms of biofouling organism, type of biofoulers and technique to prevent artificial surfaces from marine fouling organisms. The antifouling methods based on traditional chemical methods, biological methods, and physical methods are discussed. The chemical methods include such as tributyltin self-polishing copolymer base coatings, it having good performance among the other coating but this coatings cause’s serious environmental problem. Hence, we focus on other antifouling coatings include coatings with base on copper acrylate, TBT free self-polishing co-polymer coating,Non-toxic antifouling Coating mostly silicon base chemistry,Biological antifouling methods including Enzymes that degrade adhesive used for settlement, Enzyme that disrupt the biofilm matrix, Enzyme that generate deterrents and biocides, Physical methods. In this review paper, most of the focused non-toxic antifouling technologies are discussed. It is concluded that Low Surface Energy Anti-fouling Coatings, Modified Organic Silicone Anti-fouling Coatings, Modified Organic Fluorine Anti-fouling Coatings, Fluorine Silicone Resin Anti-fouling Coatings because of their excellent effectiveness and low toxicity.

Client Server Architecture for IT Company

The client server communication via wired or wireless LAN is an important feature of every company. The project creates an effective file sharing client server application via LAN for an IT company. In modern IT companies have different types of application for communication. The file sharing system and broadcast nature via client server architecture is a tedious one. The project aim to create a new client server communication architecture for IT Company, which helps to send files, message to the department or a single employee.

Performance Estimation of OFDM in Multipath Rayleigh Fading Channel

In recent years high speed wireless data communications have increasingly been used in many application areas like Orthogonal Frequency Division Multiplexing (OFDM) .The principles of OFDM modulation have been in theory from a long time. But in recent years, this technology has crossed the limitations into the real world of modern communication systems to combat Inter Symbol Interference (ISI) through multicarrier modulation. OFDM has proved to be very effective in mitigating adverse multipath effects of a broadband wireless channel. Counteracting the frequency selectivity of multipath channels by multiplexing information on different orthogonal carriers is the key to the OFDM success. In this research work, the aim is to figure out the way, for improving the performance of transmitting information. Various kinds of modulation techniques will be studied in terms of their performance in a virtual Rayleigh Channel environment. The average BER performance for different MPSK and M-QAM will be evaluated and use of gray coded bit mapping for different modulation schemes to get BER performance with OFDM technique The numerical results are computed and plotted for M=16 and 64

Design and Analysis of Casted Mecanum Wheel

In this study, an attempt has been made to design and manufacture the mecanum wheels by using aluminium alloys. Sand casting is adopted as the fabrication technique. The study was also extended to understand the load carrying capacity of the mecanum wheel using standard compression test of universal testing machine. It was observed that single wheel can withstand maximum load of 340 Kg. It is also observed the hardness number up to 170 BHN (Brinell hardness number) was achieved through the casted aluminium product.

Electricity Theft in India: Its Measure and Solution

The paper discusses the power theft problem occurring in the Indian scenario and the problems associated with it. The power theft is categorized as the non technical losses.the amount of power theft in India varies with different states . In this paper effect of power theft on distribution of power is analysed. Intensity of usage of tube-wells, linked to unmetered electricity use by farmers increases the power theft.methods of power theft are discussed and various measures to control is discussed in this paper.

A Survey of Monitoring and Controlling Power Theft Problem in Local Area

The paper discusses the distribution structure of Talapara Bilaspur Chattisgarh and how the power theft problem in this area is monitored and controlled. Almost about 7000 houses are located and power theft problem is very popular in this area. Illegal consumption of electricity or electricity theft constitutes a major share of NTL (Non-Technical Losses). This dissertation discusses several methods implemented by illegal consumers for stealing electricity a comprehensive review of the advantages, challenges, and technologies involved in the design, development, and deployment of smart meters is presented and distribution wire of aluminum is replaced by rubber coating and insulating wire. Illegal consumer used a non linear load like cooking heater, water heater, freezer, washing machine, tube light, exhaust fan, CFL etc. The theft of power overloads the distribution system and causes low voltage, voltage dips problem and generate heavy harmonics in power system.
