 Abstract

In the field of image processing, image enhancement is one of the central tasks. On applying conversion of an image from one form to another form using operations for example compressing, scanning, storing, digitizing, and transmitting and so on, some loss of image details occurs in the output. Therefore, the image has to undertake a process of adjusting contrast called image enhancement. Image enhancement incorporates different classes of spatial operations to escalate the contrast, smoothen the areas of image, and sharpen the edges and structures. Hence, it gives a clear, a more visible and a distinct image as its output. There exists numerous techniques for improving the image quality, including: histogram techniques, gray-level modification, filters based on order statistics, filters which use Fourier/ Wavelet transform, adaptive and morphological filters, fuzzy logic. Because of its non-linear and knowledge based nature, fuzzy technique provides an appropriate framework for the implementation of various methods. In this paper, existing techniques for image enhancement have been compared and analyzed based upon different key descriptors.

 Abstract

The paper explores the intricacies of the film, Kingdom of Diamonds, directed by the acclaimed cinematic artist, Satyajit Ray. The filmmaker portrays the structural violence of the imperialistic force on the common people of the society through the archetypal representation of the kingdom. Various microcosmic examples are used by the filmmaker to expose the negative impacts of the structural violence. Moreover, the film uses the powerful symbolism of the brainwashing machine that is used to punish the commoners by the despotic ruler of the kingdom. The writing discusses the manner in which the filmmaker exudes the tendency of the powerful force to consolidate its omnipotence through the establishment of the huge idol. The film’s portraiture of the final subversive act of the common people represents the friction between the powerful and the oppressed people. As such, the socio-political commentary of the filmic narrative has been decoded in the paper.

 Abstract

At present industries are using an individual controller for controlling their individual parameters. The main aim of this project is to use a single controller for controlling more than one parameter in a fully automatic mode. In our state, there is a scarcity of electrical energy due to which EB provide limited amount of energy for us to utilize, which when exceeded we have to pay penalty. In order to overcome this problem in our project we have designed a low cost PIC microcontroller which will sense on load utilization and will send the control signal to the load tripper relay in such a way near our consumption does not exceed. Also it prevents us from paying penalty to EB. This project help in maintain data base and also, gives a voice command and in addition 2 phase voltage, current, and power can be monitored and controlled.

 Abstract

Under water communications draws the attention of researchers of different fields as this has many applications in the areas of sea diver communications and environment monitoring. The challenges that stop achieving a reliable communication in underwater are noise, limited bandwidth and power resources and harsh ambient conditions. As acoustic waves severely affected by ambient noise, multipath propagation and fading leads to large propagation delays which made the acoustic channel to be not a reliable one. In this paper Magnetic Induction (MI) channel is modelled and its performance measures are studied. MI channel can achieve low path loss and better Signal to Noise Ratio (SNR).

 Abstract

An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. With short circuit capabilities of power systems getting larger, and the voltage levels going higher the conventional current transformers becomes more bulky and costly. It appears that the newly emerged MOCT technology provides a solution for many of the problems by the conventional current transformers. MOCT measures the rotation angle of the plane polarized lights caused by the magnetic field and convert it into a signal of few volts proportional to the magnetic field. Main advantage of an MOCT is that there is no need to break the conductor to enclose the optical path in the current carrying circuit and there is no electromagnetic interference.

 Abstract

Rapid Industrialization & Urbanization coupled with increase in vehicular traffic in urban areas has become threat to air quality. An Air Quality Index is an interpretive technique, which transforms complex data on measured atmospheric pollutant concentrations into a single number or set of numbers in order to make the data more reasonable. When two or more pollutants are present in the air in significant amounts, the cumulative effect is observed using Air Quality Index. AQI gives clear picture of Air Quality. The parameters used for Air Quality Index are SO2, NOx & SPM. In the present study Air Quality Index was calculated at Abids Site to evaluate the status of air pollution continuously and to assess its impact on human health.

 Abstract

One of the main purposes of Highway failure and its maintenance is to provide a better road surface for the road users and carry traffic smoothly and safely with minimum cost. Paved roads in tropical and sub-tropical climates often deteriorate in different ways to those in temperate regions, because of the harsh climatic conditions, lack of proper design and quality control, high loads and inadequate assessment for identifying causes of distresses before carrying out maintenance and rehabilitation. A pavement distress that occurs at the surface can have a number of different causes which must be properly identified before corrective action is taken. Proper maintenance is very essential for longer life of the road surface. In this thesis work, describe a maximum possible cause of failure of different roads and also be discussed maintenance technique to repair the road surface using different pavement maintenance materials. Coir Geotextiles and Polygaurd is used in the road construction maintenance to avoid the chances of the pavement failure and accidental cases.
