Abstract:

This paper presents the design and performance of inset feed hexagonal patch antenna for miniaturization, bandwidth enhancement and circular polarization. Along with the novel geometry, a 2X1 array and 2X2 array of hexagonal patch has also been implemented. The prototype of the antenna has been designed and simulated on ADS (Advanced Design System). By implementing the hexagonal geometry, impedance bandwidth has improved by 62.8% and the gain has been enhanced by 14.2%.The designed antenna resonates at a frequency of 5Ghz.Nowadays,this frequency band is being used extensively in various applications which primarily include Wi-Fi and WLAN, which earlier was used in 2.4 GHz frequency band. A comparative study of hexagonal geometry with rectangular geometry arrays has been presented in terms of impedance bandwidth, gain and polarizations. The designed hexagonal array antennas have been fabricated by CNC Engraver while the rectangular geometry arrays by photo-lithographic method. The design is fabricated and tested on Vector Network Analyzer (VNA).It is found that the stimulated results are in close proximity with the fabricated ones. The antenna design can be used in modern day mobile communication due to its optimized area coverage along with enhanced bandwidth.

Keywords: Impedance Bandwidth, Circular Polarization, Gain, CNC Engraver, Vector Network Analyzer.

Abstract:

Due to the covid-19 pandemic, the lockdown has been implemented throughout India since mid-march 2020. This paper discusses the comparative analysis of air quality for two consecutive years 2019 and 2020 in the Pune region with data obtained from the Central Pollution Control Board (CPCB), and real-time verification, with a survey of over 100 families across Pune. This paper also determines and crosschecks possible sources for predominant pollutants during the lockdown period along with the meteorological factors. Due to restriction of activities during lockdown such as industrial, transportation, commercial, etc, a significant average reduction in pollutants was observed. During lockdown (20 March-20 May), calculations with observed data indicate 57% reduction in PM2.5, 46% reduction in PM10, 25% reduction in NO2, 49% reduction in ozone, 10- 15% reduction in SO2 and 42% reduction in AQI. The preceding figures signify the city received better air quality after decades. However, a significant hike was observed in CO. The analysis shows that strict lockdown can not only keep people safe from covid but also has the potential to heal the environment.

Keywords: AQI, CO, Covid-19, NO2, O3, Particulate matter, SO2.

Abstract:

Healthcare is undergoing a paradigm shift toward a much greater quality of care delivery. The better care of patients is the driving force behind modernizing many processes; there are plenty of other factors—such as compliance, getting more value out of existing technology investments and workflows implementation, for example, integration of electronic health records (EHR). E-health clouds provide the possibility to easily access the medical data and it provides opportunities to build new business models. It also requires Good coordination and data visualization for the identification of high-risk patients. Many Cloud implementation techniques are made by researchers to collect and utilize patient data effectively. It is important to analyses and identifies the High-risk patient so that prior medications can be done to them. Health Cloud can give healthcare organizations a complete view of patients with rich data from current conditions to medications. It enables a focus on the entire patient history It integrated with EHR and other healthcare systems and get a complete view of the patient's conditions. Einstein Analytics feature on Health Cloud can drive intelligent patient engagement and improve care effectiveness, and manage patient risk. Such type of analysis expert can improve the healthcare industry.

Keywords: E-Health Cloud, Healthcare Data Ecosystem, Einstein Analytics.

Abstract:

Li-fi which is also referred to as Visible Light Communication (VLC), is a combination of “Wi-Fi” and “Light”. As we all know that the conventional Wi-Fi uses radio waves for transmitting and receiving data but in our project visible light will be used for the same. As a state-of-the-art technology, it’s application can be found everywhere in the world, both in the field of industry as well as research; mostly because of its economic viability, high expandability and extreme efficiency and performance. Our project, although introductory, may be an extensive validity of concepts, with enhanced circuits and an extended communication truce executed simultaneously to successfully implement the sending and receiving of various data or information.

Keywords: Li-Fi (Light Fidelity), Wi-Fi (Wireless Fidelity), VLC (Visible Light Communication), LOS (Line of Sight).

Abstract:

This paper present a design of stacked rectangular dielectric resonator antenna provides 52.57 degree beam width and gain 6.9 dBi which operate in 5 to 8 GHz range of frequencies by stacking of descending order of permittivity from 20 to 10 of 1.5mm height of every block. A 50 ohm microstrip line is employed in proposed antenna as feeding mechanism. A novel different beam aperture coupled DRA is proposed which consists of multi-layered rectangular geometry of ceramic disk of various dielectric constant joined to realize the specified height. The parameter of antenna is 15x18x1.5 mm3 with grounded substrate size: 50x50 mm2. The proposed antenna is suitable for C and X band application.

Abstract:

Development is an indispensable part in the information technology field. The Internet of Things (IoT) basically opens door for all devices, appliances, and software to share and communicate information over the Internet. The shared data contains a large amount of secretive information, thus preserving information security on the shared data is an important issue that cannot be neglected. To secure data linked with IOT, blockchain is combined with IOT. IOT when implemented with blockchain is of great advantage to us. Here, the various characteristics, challenges and applications related to IOT are studied. Also, the Blockchain architecture and challenges are discussed in brief. In this work, the two IOT cases are considered; one for COVID-19 and another for Defense System.  In both the cases the security and privacy issues are discussed and the solution is proposed in context of the blockchain. 

Keywords: Internet of things (IoT), blockchain, privacy.
