Effect of optical lattice potentials on the vortices in rotating dipolar Bose-Einstein condensates

We study the interplay of dipole-dipole interaction and optical lattice (OL) potential of varying depths on the formation and dynamics of vortices in rotating dipolar Bose-Einstein condensates. By numerically solving the time-dependent quasi-two dimensional Gross-Pitaevskii equation, we analyse the consequence of dipole-dipole interaction on vortex nucleation, vortex structure, critical rotation frequency and number of vortices for a range of OL depths. Rapid creation of vortices has been observed due to supplementary symmetry breaking provided by the OL in addition to the dipolar interaction. Also the critical rotation frequency decreases with an increase in the depth of the OL. Further, at lower rotation frequencies the number of vortices increases on increasing the depth of OL while it decreases at higher rotation frequencies. This variation in the number of vortices has been confirmed by calculating the rms radius, which shrinks in deep optical lattice at higher rotation frequencies.Comment: 10 pages, 7 figure

Winery Professional Internship In Jose Maria da Fonseca

Vinifera Euromaster - European Master in Viticulture and Oenology Engineering / Instituto Superior de Agronomia. Universidade de Lisboa / Montpellier SupAgroThe present Master Thesis is about Professional Internship which is based on the study of different techniques, protocols and procedures of Wine Production by several conventional and developed method professionally performed in a respected and well recognized company José Maria da Fonseca based in Setubal Peninsula, Portugal .The winery was founded in 1834, making his mark as the biggest wine company of Portugal. With the great old history of wine production, the company has always shown its concern to develop and adopt new effective scientific ways to produce wine of better quality and to superior extent. The company is currently operating on 7th generation wine production which is totally dedicated to produce great brands of Portuguese wine. The company is lashed with highly potent and efficient wine makers along with new tools, equipment, technology and structured export model. The company is currently exporting nearly 70 percent of its overall production providing the blend of wine to the tables of different countries like USA and many others. This report comprises the basic idea and working protocols for a professional intern on how to perform several practices of wine production in the vineyard as well as in the cellar to be a professional wine maker. Although, this report readily focuses on cellar based work in wine production. While we know great wine comes from the great grapes (quality-wise) for that proper harvesting is a major and quality-decisive process in a vineyard for the vines. Pruning is performed during January and February, known as winter pruning, Pruning is a very cost-effective procedure in wine production. A proper pruning is required to be done for good quality wine. Pruning is a time consuming procedure. Introduced a new technique called mechanical pruning by using pneumatic system of switcher attached with the tractor for pruning vines to save lot of time and cost. To make the wine commercialize have a set of guidelines asserted by International Organisation of Vine and Wine (OIV) and Instituto da Vinha e do Vinho (IVV) is needed to be followed to check the essential chemical parameters to know the wines’ status and also the quality control. Which performed all along the year, at the time April. I joined laboratory and have performed the chemical parameters checking which to finish the aging and prior to bottling steps to commercialize the wines. The parameters are measured, those are pH, Total Acidity, Volatile Acidity, Alcoholic Strength, Residual sugar (Fructose, Glucose), Total and Free SO2, The main task is to keep the wine stable in the cellar and protect and preserve it from any microbiological spoilage which is mandatory for bottled wines. Periodically in order by the seasons (months) at the time of August have performed in the cellar for the harvest time in vinification process. Also, application of some new technologies for the enhanced production of wine to a larger scale have been discussed to make the production more profitable and less time consuming. This professional internship is very beneficiary for the master student to have all knowledge to run a winery as an EnologistN/

Using Machine Learning to Predict Readmissions of Diabetes Patients

We live in an era where machine learning and data science play a pivotal role in almost all of the fields. Healthcare is one such field where the implementation of cutting-edge machine learning tools are used to predict, prevent, and cure diseases in a timely manner. Readmission of patients after their discharge from a medical facility has a significant impact on the cost and patient health. In this scenario, this project ventures out to utilize the historic data of diabetes patients to predict their re-admission based on a variety of diagnostic tests performed over the course of the time that the patient is in the hospital. The methodology is to employ machine learning classification algorithms such as Logistic Regression, Decision Trees, Random Forest, K-Nearest Neighbors (KNN), Linear Discriminant Analysis, and Stochastic Gradient Descent to classify a patient as to whether he/she would be readmitted or not. This project uses Recursive Feature Elimination technique to figure out the most important features that can be used as predictors to predict the readmission of patients. This information could be utilized on new patients such that based on the few diagnostic test results performed on the patient while he/she is treated in the hospital, we would be able to get a clearer picture of the patient concerning re-admissions. The model evaluation metrics that were used are Training Accuracy, Testing Accuracy, Precision, Recall, F-1 score, and Confusion Matrix

Polyvinyl alcohol size recovery and reuse via vacuum flash evaporation

Polyvinyl alcohol (PVA) desize effluent is a high COD contributor to towel manufacturing plant's Primary Oxygenation Treatment of Water operation, and being non-biodegradable, is a threat to the environment. When all-PVA/wax size is used in weaving, significant incentives exist to recover the synthetic polymer material from the desize wash water stream and reuse it. A new technology that would eliminate the disadvantages of the current Reverse Osmosis Ultrafiltration (UF) PVA recovery process is Vacuum Flash Evaporation (VFE). This research adapts the VFE process to the recovery and reuse of all-PVA size emanating from towel manufacturing, and compares the economics of its implementation in a model plant to current plant systems that use PVA/starch blend sizes with no materials/water recovery. After bench scale research optimized the VFE PVA recovery process from the desize effluent and determined the mass of virgin PVA that was required to be added to the final, recycled PVA size formulations. The physical changes in the recycled size film and yarn composite properties from those of the initial (conventional) slashing were determined using a number of characterization techniques, including DSC, TGA, SEM, tensile testing, viscometry, number of abrasion cycles to first yarn breaks, microscopy and contact angle measurements. Cotton chemical impurities extracted from the yarns during desizing played an important role in the recovered PVA film physical properties. The recovered PVA improved the slashed yarn weave ability. Along with recovered PVA, pure hot water was recovered from the VFE. Virgin wax adds to the final, recycled size formulations were determined to be unnecessary, as the impurities extracted into the desize effluent stream performed the same functions in the size as the wax. Using the bench results, the overall VFE process was optimized and demonstrated to be technically viable through six cycles, proof-of-concept trials conducted on a Webtex Continuous Pilot Slasher. Based on the pilot scale trials, comparative economics were developed. Incorporation of the VFE technology for PVA size recovery and recycling resulted in ~$3.2M/year in savings over the conventional PVA/starch/wax process, yielding a raw ROI of less than one year based on a$3M turnkey capital investment.Ph.D.Committee Chair: Dr. Cook, Fred L.; Committee Member: Dr. Carr, Wallace W.; Committee Member: Dr. Parachuru, Radhakrishnaiah; Committee Member: Dr. Realff, Matthew J.; Committee Member: Dr. Muzzy, John D
