In this context, Web scraping for Big Data is a technique that has gained importance because of its rapidity and efficiency in gathering data for Big Data technology. This study was conducted to propose a Web Scraping framework for descriptive analysis of meteorological Big Data. The introduced framework makes it possible to extract a set of data to process it, present it in a form that is easier to analyze and understand, and use it for decision-making purposes about weather forecasts. The study employed descriptive analysis of available big data as it allows one to easily make quality and effective decisions. The web scraping process takes place in several stages, including data extraction, data archiving in a data warehouse, and finally data filtering and analysis. To test its applicability, the proposed web scraping framework was implemented and tested in the meteorological context to extract and present meteorological data issued from a specialized web source. The proposed system makes it possible to restore the data in the form of statistical models published in a dashboard. The results of the study revealed that the predictive models provided by the system are capable of predicting certain weather-related variables, such as humidity, precipitation, and temperature. The opportunities and implications to leverage the results of this study are many, including weather forecasting and decision support.

Research paper thumbnail of Effect of the pulsed laser deposition conditions on the tribological properties of thin-film nanostructured coatings based on molybdenum diselenide and carbon

Technical Physics, 2012

The structural state and tribological properties of gradient and composite antifriction coatings ... more The structural state and tribological properties of gradient and composite antifriction coatings produced by pulsed laser codeposition from MoSe 2 (Ni) and graphite targets are studied. The coatings are deposited onto steel substrates in vacuum and an inert gas, and an antidrop shield is used to prevent the dep osition of micron size particles from a laser jet onto the coating. The deposition of a laser jet from the graphite target and the application of a negative potential to the substrate ensure additional high energy atom bom bardment of growing coatings. Comparative tribological tests performed at a relative air humidity of ~50% demonstrate that the "drop free" deposition of a laser induced atomic flux in the shield shadow significantly improves the antifriction properties of MoSe x coatings, decreasing the friction coefficient from 0.07 to 0.04. The best tribological properties, which combine a low friction coefficient and high wear resistance, are detected in drop free MoSe x coatings additionally alloyed with carbon (up to ~55 at %) and subjected to effective bombardment by high energy atoms during growth. Under these conditions, a dense nanocompos ite structure containing the self lubricating MoSe 2 phase and an amorphous carbon phase with a rather high concentration of diamond bonds forms.

For this purpose, two models are proposed that are expressed as a blend of two functions which reflect the effect of the temperature and the wetness. In addition, we provide an original method to _t the proposed models by employing simple techniques that can constitute an easy-to-use tool for simulation, prediction and/or control. Moreover, the method accuracy and efficiency are evaluated for some reported works in the literature. Computational results are provided to show the validity and effectiveness of the proposed epidemic models for some plant infections.

The bactiguard coating is firmly bound to the surface of the device and reduces the adhesion and growth of microbes. This occurs without any pharmacological or toxic effect. The solution is unique. It is effective and, at the same time, biocompatible and tissue friendly, which increases patient safety. Bactiguard infection protection is thus an important component in the prevention of hospital acquired infection (HAI) and reduced use of antibiotics. The study will consist in an open, randomized, and parallel clinical trial with blinded assessment. The study will include 33 pa ents who require prolonged urethral catheterization as a method of bladder voiding who visited the polyclinic of surgical subspecialty hospital, medical city complex for the period from November 2014 to December 2015. To all 33 patients urinary ...

The simulation results are provided for the validation and in order to show the effectiveness of the proposed epidemic models for diverse plant infections reported in the literature.

Objectives In this study, we aimed to determine if there is a significant relationship between lower pole ratio (infundibular length: infundibular width) on preoperative excretory urograms and stone fragment clearances after shockwave lithotripsy. Methods A total of 60 patients with isolated lower pole stones were prospectively included in the study. Anatomical factors, such as infundibular length and width were measured and the lower pole ratio was calculated on pretreatment excretory urogram. Stone fragment clearance was assessed on periodic follow up visits (1-8weeks) with a plain abdominal X-ray for kidney, ureter and bladder. Results The overall eight-week stone-free rate was 56.66%. Mean stone size ± SD was 11.383 ± 5 mm, mean infundibular length was 11.95 ± 6.52 mm, mean infundibular width was 4.25 ± 1.6...

Such models are fundamentally characterized by the influence of some meteorological variables. In this paper, we design a new model to predict incidence of infection by pathogens in function of the mixed effects of temperature and wetness. These deeply influential parameters are estimated and adjusted with regards to the disease caused by various infectious pathogens. In addition, we show that it is primordial to introduce bound constraints on the model’s location parameters. This allows to perform a more accurate minimization of the sum of residuals. The proposed optimization procedure is based on the trust-region method. Our methodological approach is simple and easy to implement for the prediction and / or control of diverse plant infections. In order to show its efficiency, our model is validated and compared for different plant diseases adapted from se...
