In this paper, we proposed a compact photonic crystal based double hole nano cavity pressure Sensor. The Pressure Sensor is designed by introducing double hole nano-cavity with some side holes in the middle of line defect waveguide. This increases sensor Sensitivity, Quality factor and Resolution factor. Nano Pressure sensor works on the principle of resonance wavelength shift, with the applied pressure. According to the results of proposed design, the shift of resonant wavelength lies in the Optical range. This sensor works in optical S and C band. The sensitivity of silicon membrane based Pressure Sensor is 0.50nm/GPa and its minimum detectable pressure is 0.04 nN. By using plane wave expansion (PWE) method band gap of the structure is evaluated. Finite difference time domain (FDTD) method is utilized for computation of transmission power and field distribution of proposed sensor.

Diffuse optical tomography (DOT) is a noninvasive diagnostic imaging technique which uses near infrared (NIR) light to measure optical properties of tissue. Absorption and scattering are the major optical properties of the tissue which can characterize tissue functional and metabolic activities. The basic idea of diffuse optical tomography imaging is to illuminate the tissue with an array of light sources and to measure the light leaving the tissue with an array of detectors. DOT imaging system comprises light illuminating and light detector system, and a controlling unit. The controlling unit controls and synchronizes various components of the DOT system to acquire high speed optical measurement data. The data are sent to a high performance computing unit to reconstruct high speed 3D- DOT image. In this project, high power LED will be used to illuminate the tissue because of its simple design, fast response times, good intensity characteristics, cost effective and efficient modulation up to 100 to 150 MHz. For the detection of the diffused light Silicon photo detectors will be used as it is cost effective and compact. In this project, building of an instrument which can illuminate tissue and measure diffused light at high speed as well as accurately is the aim. To achieve high speed controlling, compact design and fast data acquisition, Raspberry Pi is used. By building such a system cost effective high speed optical data measurement can be achieved along with a compact design and good accuracy.

The concept of feature detection is a method to compute abstraction of image information at every point of an image and making local decision at that particular point that there is a feature in an image or not under image processing and computer vision. An interesting part of an image can be called as feature. In this paper I have done the comparison between three keypoint descriptors and have proposed a new combined approach to detect the keypoints present in an image. One of the descriptor is well known as SURF descriptor and other two are new in the fields which are called BRISK and FREAK. In this paper comparison is done between the three descriptor in terms of the Number of Features detected and Time Taken by each of the descriptors to do so. Thus by dividing the time by the number of feature we can calculate the average time taken for a single feature lesser the number greater is Descriptor in terms of speed and lesser computation power. In the end I have made a flow chart of new proposed methodology which I will work to implement that proposed methodology and compare them with the other descriptor in my future work.

The water quality data of Kukkarahalli Lake for 13 years obtained from KSPCB was analyzed for trends using Box-and Whisker’s plots, Mann–Kendall test, Exceedance Probability plots and Principal Component Analysis. Mann-Kendall test performed for water quality data interprets that there is increasing trend in the BOD concentrations while decreasing trend in DO concentration indicating deterioration of the water quality of lake. The increasing trend for phosphate and nitrate concentration also indicates that the state of the lake is turning eutrophic. The exceedance probability curves indicated that the BOD and phosphate concentrations exceeded the permissible limit for more than 62% and 95% of the total time period. DO values were lower than 4 mg/L for about 36% of the entire time period which indicates that the sustaining aquatic life is adversely affected while nitrate concentrations did not exceed the permissible limits. The variance explained by the principal components varied among the years in the study period.

Abstract— For the Effective energy utilization and its management to minimizing irreversibility has made human to look for efficient energy consumption & conversion. The energy supply to demand narrowing down day by day around the world, the growing demand of power has made the power plants of scientific interest, but most of the power plants are designed by the energetic performance criteria based on first law of thermodynamics only. The real useful energy loss cannot be justified by the fist law of thermodynamics, because it does not differentiate between the quality and quantity of energy. The aim of this research work is the comparison of energy and exergy analysis of cogeneration power plants. In this thesis work calculation of energy loss and exergy destruction of various components of Indian Glycol cogeneration thermal power plant has been done.
