As a result, websites started showing more and more consent management modules–i.e., Consent Banners–the visitors have to interact with to access the website content. Since these banners change the content the browser loads, they challenge web measurement collection, primarily to monitor the extent of tracking technologies, but also to measure web performance. If not correctly handled, Consent Banners prevent crawlers from observing the actual content of the websites. In this paper, we present a comprehensive measurement campaign focusing on popular websites in Europe and the US, visiting both landing and internal pages from different countries around the world. We engineer Priv-Accept , a Web crawler able to accept the Consent Banners, as most users would do in practice. It lets us compare how webpages change before and after acce...

Whilst these clinicians have mostly been infected with such a respiratory tract disease whenever they come in contact with both the disease, it was revealed in a clinical trial of COVID-19 treated persons that they had been mostly diagnosed with a respiratory tract infection when they made contact with the disease. A chest x-ray (also recognised as radiography) is a somewhat complicated imaging technique for detecting concerns in the respiratory system. Artificial intelligence is the most widely used accomplished machine learning algorithm for examining a substantial array of chest x-ray images, but it has the capacity to have a significant impact on Covid-19 testing. In this study, we have used PA interpret of x-rays tests both for covid-19 patients and safe individuals. We tested CNN templates and deep learning strategies. To review ResNeXt models and examine their performance ...

Replacing the tedious old method this system will save time, reduce the amount of work the teachers has to do and will replace the stationery material with a computer based system. This system deals with the maintenance of the student's attendance details. It generates the attendance of the student on basis of presence in class. It is maintained on the daily basis of their attendance. The staffs will be provided with the separate username & password to make the student's presence. The staffs handling the particular subjects will be responsible to mark the attendance for all students. Only if the student present on that particular period, the attendance will be marked.

In 5G, Bells Labs is aiming at the possibility of federating both 3GPP and non-3GPP resources, to create the infrastructure suited for Network Slicing. These resources must be organized and their coverage evaluated, solving two aspects: the problem of deduction (prediction of coverage interaction between resources starting from the relative positioning) and the problem of detection (estimation of resources’ signal quality). During the internship, a graph-based database has been built exploiting internal and external sources. Several techniques for both deduction and detection have been studied, among which the INF-score-based algorithm has been selected for deduction and the coverage radius estimation technique has been used to perform detection. A first baseline pipeline has been built to solve the ...

I exploit the increase in compulsory education‐work participation age from 15 to 17 in Australia's largest state. The policy primarily increased participation in schools with high enrolments in school‐based vocational education programs. By using incidents of crime, I incorporate incapacitation effects on crimes that do not lead to arrests and provide net effect of the policy. Results show substantial reduction in incidents of crime, particularly by male offenders in urban areas and suggest that the policy did not displace crime from streets to schools. Crimes against property, which are often diverted from the criminal justice system, show the largest decline.

Combustion synthesis, Precipitation Method, Sol-Gel. The samples are annealed from 600-14000C temperature. Effect of Temperature on luminescence intensity of Europium Doped Y2O3 phosphor prepared from different synthesisroutes is studied in the presented paper. Prepared samples are found to have monoclinic structure when compared with JCPDS standard data. The luminescence intensity increases with the increase of particle size and is affected by synthesis route. Eu doped Y2O3 particle shows sharp emission at 611nm at UV excitation. The samples are excited with different UV wavelength and maximum emission intensity is found when excited with 234nm wavelength. Powder X-Ray Diffraction (XRD) results indicated that high temperature leads to increase in the particle size. TEM photographs show the agglomeration of the samples at higher temperature.

Chocolate is one of the major industries causing water pollution. Considering the increased milk demand, the Chocolate industry in India is expected to grow rapidly and have the waste generation and related environmental problems are also assumed increased importance. Poorly treated wastewater with high level of pollutants caused by poor design, operation or treatment systems creates major environmental problems when discharged to the surface land or water. Various operations in a Chocolate industry may include pasteurization, cream, cheese, milk powder etc. Considering the above stated implications an attempt has been made in the present project to evaluate one of the Effluent Treatment Plant (ETP) for Chocolate waste. Samples are collected from three points; Collection tank (CT), outflow of Anaerobic Contact Filter (ACF) and Secondary clarifier (SC) to evaluate the perfo...

Cage rotor induction generators are being replaced by doubly-fed induction generator configurations. However, in this paper an attempt is made to highlight the specific features of a cage rotor bifurcated winding induction generator configuration found suitable for variable speed applications especially in the area of wind energy systems. The study based on finite element models (FEM) offers more information on the phenomena characterizing the operation of electrical machines than the classical analytical models and is convenient to develop especially if the machine is asymmetrical in its winding configuration. A model of the machine is developed using Ansys and its performance under various conditions successfully compared with the experimental results obtained on the actual machine.

Even operating systems used for mobile phones are not an exception for this fact. This paper proposes a technique for maximizing the utilization of the storage space present in mobile phones. Thus it is important to utilize the space occupied by SMS files in phone’s memory, which take maximum space. The objective involved is designing a semantic dictionary based on Intelligent Dictionary Based Encoding (IDBE) which provides a high text compression ratio to utilize the space in phone’s memory. When SMS file will be received, English words present in the text will be replaced by the respective short words in the designed semantic dictionary. Thus replacing English words by the respective short forms reduces the space occupied by the SMS file. The paper describes the IDBE Compression Techniques for SMS Text Compression.

Each year, approximately 14 per cent of teachers leave teaching (becoming a principal is not counted as leaving teaching). Most who leave return to teaching at some stage, commonly after a gap of just one or two years. This absence from teaching is typically associated with starting a family. Overall, teachers are just as satisfied with their jobs as other professionals, and express aboveaverage levels of job satisfaction in relation to job security, but below average satisfaction in relation to job flexibility (i.e. work/life balance). Those who left teaching recorded substantially lower job satisfaction on all aspects of their job while teaching, which su gests they were no longer well suited to teaching. The starting wages of full-time teachers are similar to those of other full-time professions, but their wages grow much more slowly with experience than other professions, for both males and females.
