DESIGN AND ANALYSIS OF CAR DOOR WITH S2 GLASS AND THERMO PLASTIC MATERIALS

The car door is one of the important factors which can be used as a safety for passengers from facet collisions. Side Impact crashes can be normally risky because of the fact there may be no room for massive deformation to protect an occupant from the crash forces. The component effect collision is the second biggest cause of death. Day thru day growth within the fuel price and the emission of the smoke from the auto corporation are also the fundamental issues in the current-day worldwide, as a end result, the protection, gasoline overall performance and emission gas law of the passenger cars are crucial issues inside the modern-day global. In this thesis, the auto aspect door beam modeling in CREO parametric software with particular systems of beam evaluation completed in ANSYS and COSMOS software program utility. Static, modal, fatigue evaluation doing in ANSYS software program and effect assessment by way of using COSMOS software application utility. The car door beam analyzing with wonderful loads (5000N, 6869 N and 12000N) and high-quality composite materials (carbon fiber, s2 glass, and glass mat thermoplastic material)

EXPLORATORY OF DIE CASTING PROCESS PARAMETERS TO SPOT THE OPTIMIZED INDICATES USING TAGUCHI METHOD

The present paintings analyses particular parameters of pressure die casting to reduce the casting defects. Pressure die-casting is generally carried out for the casting of aluminum alloys. Good ground finish with required tolerances and dimensional accuracy can be accomplished thru optimization of controllable method parameters which encompass solidification time, molten temperature, filling time, and injection strain and plunger speed. Moreover, via a selection of ideal manner parameters, the strain die casting defects which embody porosity, the inadequate spread of molten cloth, flash and so on. In this thesis, the major emphasis is probably on the optimization of way parameters in High-pressure die casting. A case observes of EMF load cell is taken into consideration wherein the go with the flow simulations outcomes are analyzed for optimization. An analytical technique is stated by way of manner of the usage of software program Ansys Fluent to research the behaviour of molten metallic at specific degrees of time by means of looking at the consequences of temperature versions, stress variations, and liquid fractions by way of manner of making use of the enter parameters molten metal temperature, die temperature and velocity of go together with the go together with the drift. The model of the element with spreader layout, runner layout, a gate area and overflows is finished in three-d modelling software program Pro/Engineer

Unstructured Peer-to-Peer Botnet Simulation for Measuring Its Robustness

Malware attacks on the Internet have increasedsubstantially in recent years for which botnets are a root cause. A "botnet" is a network of compromised computers controlled by an attacker known as the "botmaster". To be able to effectively detect and defend against botnets, it is very important to have a good understanding of their construction procedure and propagation methodology. In this work, we study the construction of an unstructured peer-to-peer botnet, its propagation methodology, diurnal properties and robustness. This simulation shows that the more frequently a node updates its buddy list, the lesser is the process overhead involved

3-[2-(2,6-Dichloro­anilino)benz­yl]-4-[(4-meth­oxy­benzyl­idene)amino]-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C23H19Cl2N5OS, the triazole ring makes dihedral angles of 24.81 (18), 69.94 (19) and 35.68 (18)° with the dichloro­phenyl, benzene and meth­oxy­phenyl rings, respectively. An intra­molecular N—H⋯N hydrogen bond occurs. In the crystal, inversion dimers linked by pairs of N—H⋯S hydrogen bonds occur. In addition, there are weak C—H⋯π inter­actions involving the dichloro­phenyl and triazole rings

Challenges and opportunities in mixed method data collection on mental health issues of health care workers during COVID-19 pandemic in India

Background: The present paper describes the key challenges and opportunities of mixed method telephonic data collection for mental health research using field notes and the experiences of the investigators in a multicenter study in ten sites of India. The study was conducted in public and private hospitals to understand the mental health status, social stigma and coping strategies of different healthcare personnel during the COVID-19 pandemic in India.Methods: Qualitative and quantitative interviews were conducted telephonically. The experiences of data collection were noted as a field notes/diary by the data collectors and principal investigators.Results: The interviewers reported challenges such as network issues, lack of transfer of visual cues and sensitive content of data. Although the telephonic interviews present various challenges in mixed method data collection, it can be used as an alternative to face-to-face data collection using available technology.Conclusions: It is important that the investigators are well trained keeping these challenges in mind so that their capacity is built to deal with these challenges and good quality data is obtained

Factors associated with stigma and manifestations experienced by Indian health care workers involved in COVID-19 management in India: A qualitative study

Healthcare personnel who deal with COVID-19 experience stigma. There is a lack of national-level representative qualitative data to study COVID-19-related stigma among healthcare workers in India. The present study explores factors associated with stigma and manifestations experienced by Indian healthcare workers involved in COVID-19 management. We conducted in-depth interviews across 10 centres in India, which were analysed using NVivo software version 12. Thematic and sentiment analysis was performed to gain deep insights into the complex phenomenon by categorising the qualitative data into meaningful and related categories. Healthcare workers (HCW) usually addressed the stigma they encountered when doing their COVID duties under the superordinate theme of stigma. Among them, 77.42% said they had been stigmatised in some way. Analyses revealed seven interrelated themes surrounding stigma among healthcare workers. It can be seen that the majority of the stigma and coping sentiments fall into the mixed category, followed by the negative sentiment category. This study contributes to our understanding of stigma and discrimination in low- and middle-income settings. Our data show that the emergence of fear of the virus has quickly turned into a stigma against healthcare workers

The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy

Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care
