A Generalized Log-Weibull Distribution with Bio-Medical Applications

Here we consider a generalized log-transformed version of the Weibull distribution and investigate some of its important properties like expressions for the cumulative distribution function hazard rate function, quantile function, characteristic function, raw moments, incomplete moments, etc. The distribution and moments of order statistics are obtained along with some results on certain structural properties of the distribution. The maximum likelihood estimation of the parameters of the distribution is attempted for both complete and censored data sets and the usefulness of the distribution is illustrated with the help of real-life data sets from biomedical fields

Low Cost Smart Automation System with Energy Meter

Automation and the Internet of Things (IoT) has become a hot topic in the present tech-driven world. Smart security solutions, smart home automation, smart health care, smart wearable’s etc. are in-trend applications of IoT, and by the near future we expect to see its application to a city's transportation system or smart power grids.. Nowadays there are lots of automation products that are available in the market but the cost of which is not affordable to the common man to use it at home or office. Home automation have various applications such as: Lighting control system, Appliance control and integration, Security, Leak and smoke detection, Home automation for the elderly and disabled etc[2]. Mostly all automation products needs special wiring and is not retro fit to their current switches. Automation for both smart and those who are not that smart should also be able to use automation. The research aims at finding sensors and IC’s that are cheap and with little modification on the software will reduce cost and making it small enough to fit into the current switch box so the little wiring will convert the current system to smart automatic system. It works on the principle of IOT with a central server to allow access from outside the premises of the system using mobile with internet connectivity. The energy meter also provides all the active and reactive power components of the equipment's connected to the system. In this project most of the objectives were achieved including features and cost optimization. Further research needs to incorporate camera and other security features

An extended version of Kumaraswamy inverse Weibull distribution and its properties

Here we consider an extended version of the Kumaraswamy modified inverse Weibull distribution and investigate some of its theoretical properties through deriving expressions for cumulative distribution function, reliability function, hazard rate function, quantile function, characteristic function, raw moments, median, mode etc. Certain reliability measures of the distribution are obtained along with the distribution and moments of its order statistics. The maximum likelihood estimation of the parameters of the distribution is discussed and certain real life data applications are given for illustrating the usefulness of the model. Further, with the help of simulated data sets it is shown that the average bias and mean square errors of the maximum likelihood estimators are in decreasing order as the sample size increases

On Some Properties of the Log-Weibull Distribution

Through this paper we consider some theoretical properties of the log-Weibull distribution proposed by Jiang and Wang (2013), by deriving expressions for its quantile function, moment generating function, raw moments, incomplete raw moments, percentile measures of skewness and kurtosis, median, mode and geometric mean. Some structural properties of the distribution and certain reliability measures are investigated along with a few results on order statistics. The parameters of the distribution is estimated using the maximum likelihood estimation method and their asymptotic behavior is examined with the help of simulated data sets

Cancer relapse in surgical patients who received perioperative transfusion of blood and blood products: A case-control study

Background and Aims: Immunomodulatory consequences of allogeneic blood transfusion may outweigh the advantages of improved oxygen delivery and tissue perfusion, especially in patients with cancer. In colorectal cancer, there is evidence of cancer relapse in patients who received transfusion. This retrospective analysis was undertaken to evaluate the relationship between perioperative blood transfusion and cancer recurrence in patients undergoing oncosurgery. Methods: In this case-control study, we retrospectively analysed the case sheets of 194 patients who had perioperative transfusion and underwent cancer surgery from March to December 2013(Study group, Cases). They were compared with controls matched for cancer site and TNM staging who did not receive perioperative transfusions (Control Group, Controls). We intended to find out if the Study group had any increased risk of cancer relapse compared with the controls. Records from the institute cancer registry were analysed in 2018 to give a follow-up period of 5 years. Continuous variables were analysed using Student's T test and Mann Whitney U test for normally distributed and skewed data respectively. For Categorical data Fisher's exact test and Chi square test were applied. The risk for recurrence was estimated using odds ratio. Results: The recurrence rate in cases and controls was 53.09% and 19.59% respectively and the odds ratio, 4.647 (CI: 2.954, 7.309). In Cases, significant relapse was noted for carcinomas of ovary, colorectal, bladder, larynx, head of pancreas and liver. Conclusion: In surgical oncology patients, ABT is associated with greater rate of recurrence

660-667<span style="font-size: 15.5pt;mso-bidi-font-size:8.5pt;font-family:" times="" new="" roman","serif""="">Feeding of 2% cholesterol diet increased lipid parameters in serum and tissues of rats during a period of one month. In addition to the above, lipid peroxidation also increased and activities of certain enzymes were significantly altered in the tissues. Similar changes were also observed to a greater extent with diets containing 40% by weight of coconut kernel or groundnut with and without 2% cholesterol. The enzymes studied were HMGCoA reductase, AST, ALT and ALP in tissues and serum as the case may be. In general the atherogenic effects were observed more with groundnut containing diets than those with coconut. Even though the oil from the former is mostly unsaturated and that from the latter is mostly saturated, these analytical criteria do not relate to their atherogenic effects. When 5% garlic was incorporated with any of the high fat diets, the lipid parameters, their peroxidation and alterations in enzyme activities were significantly decreased. These results show that garlic contains some principles that counteract the atherogenicity of the above oil seeds. </span

CO2 absorption studies on mixed alkali orthosilicates containing rare-earth second-phase additives

© 2015 American Chemical Society. Lithium silicate containing eutectic orthosilicate mixtures developed by a solid-state route displayed excellent characteristics as carbon dioxide absorbents at elevated temperature, showing absorption capacity of 256 mg g-1. Incorporation of second-phase materials was investigated as a strategy to enhance the stability of the absorbent materials against agglomeration and sintering during powder processing and high-temperature cyclic absorption/desorption loading. Yttrium oxide, gadolinium oxide, and lanthanum phosphate were added as second phases to the absorbent. It was found that when the composites were rich in absorbents (10:1 and 20:1 absorbent/second phase), the absorption performance was hardly influenced by the type of the second-phase material present. Yttrium oxide or gadolinium oxide additions in large quantities were found to enhance the absorption capacity of the orthosilicate phase. The 2:1 sample containing yttrium oxide gave absorption capacity of 315 mg g-1 of orthosilicate absorbent present in the composite sample. On the basis of the structural and morphological studies, we believe that the nonreactive second-phase components formed a virtual shell against the segregation of absorbent phase, thereby helping to improve their absorption performance. Cyclic studies have supported the superior stability and performance of such composite absorbent materials
