Optimización en GPU de algoritmos para la mejora del realce y segmentación en imágenes hepáticas

This doctoral thesis deepens the GPU acceleration for liver enhancement and segmentation. With this motivation, detailed research is carried out here in a compendium of articles. The work developed is structured in three scientific contributions, the first one is based upon enhancement and tumor segmentation, the second one explores the vessel segmentation and the last is published on liver segmentation. These works are implemented on GPU with significant speedups with great scientific impact and relevance in this doctoral thesis The first work proposes cross-modality based contrast enhancement for tumor segmentation on GPU. To do this, it takes target and guidance images as an input and enhance the low quality target image by applying two dimensional histogram approach. Further it has been observed that the enhanced image provides more accurate tumor segmentation using GPU based dynamic seeded region growing. The second contribution is about fast parallel gradient based seeded region growing where static approach has been proposed and implemented on GPU for accurate vessel segmentation. The third contribution describes GPU acceleration of Chan-Vese model and cross-modality based contrast enhancement for liver segmentation

Legislature Library of Maharashtra State

The paper describes the Legislature library,one of the oldest, richest and largest libraries, managing wide ranges of information e.g. Acts & Bills, Proceedings, Gazettes, Rare books, LT papers, Old News Paper, Debates, Report etc. There is hardly any library other than Legislature library handling all kinds and variety of information resources. This makes the management and functioning of legislative library unique. The Legislature library has ‘Research and Reference’ services for members of assembly have gradually developed into what is now referred to as the library and Reference, Research, Documentation and Information service more familiar. The Legislature library is under the control of Government of Maharashtra. This easily offers information to the various users of different fields such as government officers, administrative staffs, MLAs, ex –MLAs etc.The optimum use of Legislature library is instrumental in making the members of assembly and overall function of the assembly very effective

FORMULATION AND OPTIMIZATION OF CURCUMIN SOLID DISPERSION PELLETS FOR IMPROVED SOLUBILITY

Objective: The present study was aimed at designing of solid dispersion based pellets of curcumin (Cu) for improving its solubility. Methods: Solid dispersion (SD) of Cu was prepared by the melt method using Poloxamer 407 (Pol 407) at a different weight ratio of Cu-Pol 407 (1:2, 1:3, 1:5, 1:7, 1:10). The solid dispersion was characterised by FTIR, SEM, DSC, XRD and evaluated for saturation solubility in water, drug content and in vitro dissolution. The pellets of Cu solid dispersion were prepared by extrusion spheronization technique and optimization was performed by 32full factorial design. The pellets were evaluated for size distribution, flow properties, hardness, disintegration and in vitro drug dissolution. Results: From the phase solubility analysis, Pol 407 was selected as a Solid dispersion carrier. The formation of Cu-SD by melt method using Pol 407, was confirmed from FTIR and DSC studies. XRD studies indicated a change of Cu from crystalline to amorphous form. There was a significant increase of Cu when formulated as SD compared to plain Cu. The optimization of extrusion spheronization process revealed the significant effect of Cu-Pol 407 ratio (p<0.0001) on in vitro dissolution of pellets. Higher Cu dissolution was obtained with Cu-SD pellets compared to plain Cu pellets. Conclusion: The present study demonstrated the potential of Cu-SD pellets in improving the solubility of poorly soluble Cu

Modeling phosphorus distribution under different fertigation strategies in onion (Allium cepa L.) crop

The understanding of soil and nutrient dynamics under drip fertigation is relevant for crop production as well as water and nutrient management. The aim of this study was to generate information about the distribution of phosphorus (P) under different fertigation strategies for onion production on sandy clay loam soil during 2007-2008 to 2008-2009. The study involved field experiment, laboratory analysis and modeling of P distribution. The phosphorus distribution data in the field were collected, analyzed and used to calibrate and validate the solute transport model HYDRUS-2D for sandy clay loam soil. The performance of HYDRUS-2D was evaluated by comparing its simulated values with the observed values of soil moisture and nutrient concentration. The coefficient of determination (R2), root mean square error (RMSE) and mean absolute error (MAE) were used as model performance indicators. The range of R2 between 0.72-0.99 for water as well as nutrient distribution indicates good correlation between the observed and simulated values. The MAE and RMSE values for water and nutrient distribution were in between 0.0009 to 0.0039 which indicated the accuracy of the model. From these results, it can be concluded that the model is performing well for predicting the P concentration in the soil as well as the soil moisture distribution for onion crop grown under sandy clay loam. The model was also validated for water and phosphorus distribution with the observed values at the end of the crop season and found to be performing well. The HYDRUS-2D model may be used to carry out simulations for different soil types and with different fertigation and irrigation strategies for developing guidelines

A study and comparison of COordinate Rotation DIgital Computer (CORDIC) architectures

Most of the digital signal processing applications performs operations like multiplication, addition, square-root calculation, solving linear equations etc. The physical implementation of these operations consumes a lot of hardware and, software implementation consumes large memory. Even if they are implemented in hardware, they do not provide high speed, and due to this reason, even today the software implementation dominates hardware. For realizing operations from basic to very complex ones with less hardware, a Co-ordinate Rotation Digital Computer (CORDIC) proves beneficial. It is capable of performing mathematical operations right from addition to highly complex functions with the help of arithmetic unit and shifters only. This paper gives a brief overview of various existing CORDIC architectures, their working principle, application domain and a comparison of these architectures. Different designs are available as per the target, i.e. high accuracy and precision, low area, low latency, hardware efficient, low power, reconfigurability, etc. that can be used as per the application in which the architecture needs to be employed

IoT based intelligent irrigation support system for smart farming applications

India is an agricultural country with an ample amount of arable land that produces wide variety of crops. Growing population and urbanization puts up challenges: more and quality yield in limited area, effective utilization of water resources, inculcating technology with traditional mechanisms, to be faced. A crop irrigation management system with sensor data fetch, transfer and operate functionalities is proposed to meet the expectations. The system comprises of: sensing, data processing and actuator sections, with a network of ambient temperature and humidity at a height and, soil moisture sensor placed at the root zone of the subject. The sensor generated data is compressed and then sent to an FTP server for processing. At the server, a 2-layer Neural Network with 4-Inputs, plant growth, temperature, humidity and soil moisture is used for decision making that controls water supply, fertilizer spray, etc. and a plant is used as the test object. Results show that there is tolerable error in the reconstructed data and 62.5% and 67.5% compression is achieved for ambient temperature, humidity and soil moisture respectively. The decisions are only 2% erroneous when done using Neural Networks using this data. Thus, due to its good data handling, decision making capabilities for precise water usage, being portable and user-friendly, this system proves beneficial in home gardens, greenhouses
