MODELLING AND SIMULATION OF HYBRID RENEWABLE ENERGY SOURCES CONNECTED TO UTILITY GRID

ABSTRACT The proposed system presents power-control strategies of a grid-connected hybrid generation system with versatile power transfer. This hybrid energy system allows maximum utilization of freely available renewable energy sources like wind and photovoltaic energies. For this, an adaptive MPPT algorithm will be used for the system. Also, this configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the energy sources. The turbine rotor speed is the main determinant of mechanical output from wind energy and Solar cell operating voltage in the case of output power from solar energy. Permanent Magnet Synchronous Generator is coupled with wind turbine for attaining wind energy conversion system. The inverter converts the DC output from non-conventional energy into useful AC power for the connected load. This hybrid energy system operates under normal conditions which include normal room temperature in the case of solar energy and normal wind speed at plain area in the case of wind energy. The simulation results are presented to illustrate the operating principle, feasibility and reliability of this proposed system

Website Creator by Mock-Up Images Using Machine Learning.

The first step of designing a website is to build the mock-up images for the particular web pages by operating with the hands or using mock-up developer tools. It is efficiently used for the developer to transfer web pages mock-up to the coding. It is generating the proposed system to create the wireframe to the layout interfaces. There are two techniques mostly used: first is computer vision and second is deep systematic analysis. The automatic code generation is time reducing and cost effective. The goal of this research is to automate the process of creating code from hand-drawn mock-ups. Computer vision techniques are utilised to process hand-drawn mock-ups, and then deep learning approaches are employed to construct the suggested system

DONSON and FANCM associate with different replisomes distinguished by replication timing and chromatin domain

Eukaryotic replisomes are multiprotein complexes. Here the authors reveal two distinct stressed replisomes, associated with DONSON and FANCM, displaying a bias in replication timing and chromatin domain

Reviewing Effectiveness of CAPTCHA

Abstract: The massive use of the Internet and WWW by the government and commercial organizations for automation of work has resulted in extensive proliferation of online computing. To avoid online forms being filled by bots or malicious computers the form designers usually use a cryptic image known as CAPTHA (Completely Automated Public Turing test to Tell Computers and Humans Apart) [CAPTCHA] which is human readable and the form can be submitted only when the user has decrypted the captcha and filled in the text represented by that captcha. This type of visual and textual verification comes at a huge price to users who are blind, visually impaired or dyslexic. In many cases, these systems make it impossible for users with certain disabilities to create accounts, write comments, or make purchases on these sites, that is, CAPTCHAs fail to properly recognize users with disabilities as human. Also like every security system that has preceded it, this system can be defeated by those who benefit most from doing so. For example, spammers can pay a programmer to aggregate these images and feed them one by one to a human operator, who could easily verify hundreds of them each hour. The efficacy of visual verification systems is low, and their usefulness is nullified once they are commonly exploited

Considerations in career choices for oral health professionals in Australia

Aim or Purpose: Australian universities with a curriculum focussing on underserved communities are uniquely positioned in addressing health needs and current workforce shortages of regional, rural and remote communities. This project reports on the mixed-methods study that investigated trends in graduates’ career choices and identified enablers and barriers to rural and public health practices in Bachelor of Dental Surgery (BDS) program at James Cook University (JCU). Materials and Methods: This study involved a quantitative analysis of an online survey of BDS graduates from 2013-2020, followed by qualitative semi-structured interviews with a sample of graduates focusing on their career choices. Interviews were digitally recorded, manually transcribed, and analysed thematically. Results: In the first postgraduate year, more than 4 in 5 graduates originally from non-metro areas chose to work for an employer in non-metro location enabled by extended exposure to rural and remote sites during university placements, familiarity with the physical environment, job security and lifestyle as identified through interviews. Additionally, they or their partner having a rural background was a strong indicator for retaining workforce in rural and remote areas. However, a move to metro area within subsequent few years was often noted, mainly due to lack of mentoring, support groups and/or social isolation. Conclusions: Early career choices of dental graduates aligned with the workforce needs of non-metropolitan Australia but did not translate to long term retention. Strategies to address the identified barriers could assist in greater retention of graduate dentist workforce in rural, remote and public practices
