The objective of this study is to analyse the changes in air quality between pre and during the lockdown in Asansol, the “coal mining city” of Eastern India is characterized by high pollution levels due to several industries leading to human discomfort and even health problems. Secondary data of seven parameters like CO, SO2, NO2, PM2.5, PM10, NH3, and O3 have been collected from the website of the Central Pollution Control Board, India and AQI were calculated as per the calculator provided by CPCB. The result displays a significant reduction of seven parameters from 33.31 % (SO2) to 60.44 % (PM2.5) due to the shut down of all manufacturing units and transportation throughout the lockdown period. The air quality index (AQI) was also upgraded from a very poor to a satisfactory state during this period. Plants are the main carbon sink, so, a green belt project proposal for this polluted city has been recommended to improve air quality management. This lockdown (temporarily) showed some vaccine effect on the air quality, but this is totally against economic growth.","PeriodicalId":254600,"journal":{"name":"JOURNAL OF MECHANICS OF CONTINUA AND MATHEMATICAL SCIENCES","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115140583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Huge numbers of ANPR techniques have been proposed by various researchers in the past. Most of the ANPR techniques are designed for restricted conditions due to the diversity of the license plate styles, environmental conditions etc. Not every technique is suited for all kinds of conditions. In general, the ANPR technique comprises of the following three stages; license plate detection (LPD); character segmentation; and character recognition. There exist a wide variety of techniques for carrying out each of the steps of the ANPR. Some score over others. This paper presents a State-of-the-Art survey of the various leading LPD techniques that exist today and an attempt has been made to summarize these techniques based on pros and cons and their limitations. Each technique is classified based on the features used at each stage of LPD. This survey shall help provide future direction towards the development of efficient and accurate techniques for ANPR. It shall also assist in identifying and shortlisting the methodologies that are best suited for the particular problem domain.","PeriodicalId":254600,"journal":{"name":"JOURNAL OF MECHANICS OF CONTINUA AND MATHEMATICAL SCIENCES","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124119337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though patients and healthcare staffs provide psychiatric treatment, the psychological health of the overall population often demands concern which causes psychosocial stressors, impacting both the spread of the disease and the incidence of emotional distress and psychological disorder. The study aimed to identify the psychological condition and demand as wee as the coping process of the population of the capital city-Dhaka of Bangladesh. For collecting data with these categories, the online portals, like facebook vote, Google met, LinkedIn, were used for both male and female gender. Among the participants, 35% people were depressed, in grief 4% people, 25% people were suffering from Anxiety,13% people were facing Insomnia problems and 7% people were facing Trauma. Our survey also revealed that 21%sample acknowledged to open up lockdown, on the other hand, 31% of people were consistently strongly agreed on the government decision. 34.8% of people spent their time during lockdown using Facebook, 26% on online classes, work from home were 14%, and the other 26% people were utilizing their lockdown time by watching YouTube and other social sites. This study puts together a towering contribution to developing an assessment of mental health profile during SARS-2-CoV-19 and lockdown in Dhaka.","PeriodicalId":254600,"journal":{"name":"JOURNAL OF MECHANICS OF CONTINUA AND MATHEMATICAL SCIENCES","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134381031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This thesis deals with the comparative study of wireless cellular technologies namely First Generation, Second Generation, Third Generation, and Fourth Generation. A cellular network or mobile network is a radio network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station. In a cellular network, each cell uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed bandwidth within each cell. The First Generation were referred to as cellular, which was later shortened to “cell”, Cell phone signals were based on analog system transmissions, and First Generation devices were comparatively less heavy and expensive. Second Generation phones deploy GSM technology. Global System for Mobile communications or GSM uses digital modulation to improve voice quality but the network offers limited data service. The Third Generation revolution allowed mobile telephone customers to use audio, graphics and video applications. Fourth Generation is short for fourth-generation cell phones or/and hand held devices.","PeriodicalId":254600,"journal":{"name":"JOURNAL OF MECHANICS OF CONTINUA AND MATHEMATICAL SCIENCES","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115273372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
