Online Voting System

The project "Online Voting System" aims to simplify voting in any type of election. In India, presently voting is done either using ballot paper or with EVM machines. In the traditional Voting approach, Individuals are required to visit voting stations and cast their votes. People from various locations who don’t have their voting cards are unable to cast their votes. Also, the user's validation is poor and inappropriate. Further, the conventional voting system involves a lot of manual work which is a time-consuming process. Therefore, to overcome the drawbacks in the existing system this particular system was proposed to mark our work much easier and to reduce wastage of time. This work deals with design, building and testing a online voting system that facilitates user (the person who is eligible for voting), candidate (Candidate are the users who are going to stand in elections for their respective party), Election Commission Officer (Election Commission Officer who will verify whether registered user and candidates are authentic or not) to participate in online voting. This voting system is highly secured and has a very simple, user-friendly, and reliable design. The proposed application is developed and tested to work on Ethernet and allow online voting. The user can register by giving his personal details and the image of his face which gets stored in the database presented at the central side. After the voting date is fixed and the user gets pop up notifications on his\her android phone via GCM (Google Cloud Messaging). After that the users open the application then the face authentication is done at server side using the OTP. If the user is a valid user, then OTP is sent to the user's mail address the user accesses the voting form using their OTP, casts their vote, clicks the submit button, and then logs out.

Interviews with Indigenous Māori with type 1 diabetes using open-source automated insulin delivery in the CREATE randomised trial

PurposeOpen-source automated insulin delivery (AID) is used by thousands of people with type 1 diabetes (T1D), but has unknown generalisability to marginalised ethnic groups. This study explored experiences of Indigenous Māori participants in the CREATE trial with use of an open-source AID system to identify enablers/barriers to health equity.MethodsThe CREATE randomised trial compared open-source AID (OpenAPS algorithm on an Android phone with a Bluetooth-connected pump) to sensor-augmented pump therapy. Kaupapa Māori Research methodology was used in this sub-study. Ten semi-structured interviews with Māori participants (5 children, 5 adults) and whānau (extended family) were completed. Interviews were recorded and transcribed, and data were analysed thematically. NVivo was used for descriptive and pattern coding.ResultsEnablers/barriers to equity aligned with four themes: access (to diabetes technologies), training/support, operation (of open-source AID), and outcomes. Participants described a sense of empowerment, and improved quality of life, wellbeing, and glycaemia. Parents felt reassured by the system’s ability to control glucose, and children were granted greater independence. Participants were able to use the open-source AID system with ease to suit whānau needs, and technical problems were manageable with healthcare professional support. All participants identified structures in the health system precluding equitable utilisation of diabetes technologies for Māori.ConclusionMāori experienced open-source AID positively, and aspired to use this therapy; however, structural and socio-economic barriers to equity were identified. This research proposes strength-based solutions which should be considered in the redesign of diabetes services to improve health outcomes for Māori with T1D.Trial Registration: The CREATE trial, encompassing this qualitative sub-study, was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12620000034932p) on the 20th January 2020.

The social media: the fortunate unfortunate village square for hate propaganda

This treatise is a qualitative research in philosophy and literary studies and it considers fake news (misinformation and disinformation) from the perspective of hate speech. It focuses on the social media as the contemporary day smart village square for all sorts of hate mongering. This is one of the ill-starred pitfalls of the bandwagon called “globalization”. The buzz word ‘globalization’ is a catchword that points to the prevailing moment in human history of civilization and development-the age of digital-micro-lization of the world space. The fulcrum of globalization is communicative technologies. The presence of advanced communicative technologies or facilities like the internet, satellite, android phones and other related smart gargets has made global communication now easy and swift; since these facilities have the capability to move information from one part of the globe to the other (within a slit-second). It is in this sense that the world is now called a global village. However, the paradox of this village square enabled by the social media networking is that it is relishing and at the same time palpably fraught. Positively, social media is accessible, interactive, immediate and relevant; negatively, one among the numerous causes for alarm is the rising misappropriation of social networking sites for hate speech. Employing analytic and hermeneutical methods, the philosophico-literary discourse critically interrogates the misappropriation of this artificial and synthetic neighborhood for the proliferation of all sorts of inciting, poisonous, destructive, divisive, manipulative and inflammable speeches. This study reveals that two fundamental factors are responsible for the thriving of hate speech in this techno-neighborhood, i. humans nowadays are gullible to the point of naïvely believing any information from the social media as true and correct; ii. lack of censorship and quality control of most social media. Consequently, the ultimate goal of the chapter is to seek for philosophically pragmatic remedy to this malady in order to advance the frontiers of this creative and emerging technology. Therefore, the researchers present a number of philosophico-literary theoretical frameworks and modalities to stern the tide of hate speech explosion in the social media.

Development of electrocardiogram intelligent and wearable monitoring system-assisting in care

<p>The primary factor contributing to the high mortality rate in our country is coronary heart disease, which affects almost 50% of people from rural regions. Internet of things (IoT) contributes effectively to the development of point of care (POC) gadgets that support the medical upkeep of an expanding agricultural population. An electrocardiogram test is crucial for analysing cardiac disorders. Therefore, we must develop a POC piece of hardware to assess the health of the heart in an affordable manner and to design it for the patients without interfering with their daily regular procedure in order to monitor the patient's coronary heart disease. As a result, we must design an uninterrupted workbench, which consists of three main integrated parts. The first is a mobile Bluetooth low energy device that has 5-lead electrocardiogram (ECG) surveillance equipment and the smallest form factor. The smart phone Android application that inherits, resolves, and maps the data sent from the ECG device comes next. The patient's information and report details are then compiled on a cloud server for the doctor's future attribution needs.</p>

An artificial pancreas system in android phones: A dual app architecture

An Artificial Pancreas (AP) system centered around an Android Smartphone is proposed in this paper. This unique architecture involves two separate but interacting modular Android applications (Apps) that are designed for unique functionalities. Even though an artificial pancreas system is a safety-critical system that demands a complex architecture and careful coding process, owing to their modular nature, these apps could be designed and developed through rapid prototyping processes. The first app (App-A), which runs in the front-end, serves as the user interface and acts as a connection hub for the hardware devices, was developed on the Android studio platform. Necessary communication protocols to enable communication with the hardware devices are incorporated into this app. The second app (App-B), which runs in the back-end, is developed using Simulink’s Android support package. It contains a safety-critical model predictive control algorithm with appropriate constraints to compute the required insulin rate, augmented with a Kalman Filter for estimating the states. There is an additional safety logic as well to prevent insulin over-dosage, thereby augmenting to the cause of a safety-critical control algorithm. The contribution of this work is a modular software framework and prototyping methodology that can be used for rapid development, testing and deployment of Android based AP-systems.

Digitalisasi Museum Cakraningrat sebagai Sumber Literasi Edukasi pada Siswa Di Era Disrupsi 5.0

Museums are a source of knowledge and literacy for their visitors. However, so far, museum visitors only stop by and don't discuss comprehensive data related to objects seen by visitors. Others create interest in museums by digitizing the objects in them. So this research is a preliminary study before developing barcodes. This research is a preliminary study prior to the development of learning media for literary language and its barcode-based teaching for reading skills to facilitate the learning process in museums and educate local knowledge about relics that are full of information and knowledge.

The role of social norms on adolescent family planning in rural Kilifi county, Kenya.

Despite Kenya's encouraging progress in increasing access to modern contraception among youth, several barriers remain preventing large-scale efforts to reduce demand-side unmet need for family planning. Shifting social norms around the use and acceptability of modern contraception may represent a potent target for future interventions. However, the structure of normative influence on individual modern contraceptive use among youth needs to be determined. Therefore, our aim was to estimate the influence of individual and group-level normative influence on modern contraceptive use among adolescents from two villages in rural Kenya. Trained enumerators collected data from individuals aged 15-24 who provided oral informed consent, or parental informed consent, in two villages in rural Kilifi county. Participants completed a questionnaire related to modern contraceptive use and were asked to nominate one to five people (referents) with whom they spend free time. The enumerators photographed each individual who nominated at least one referent using Android phones and matched them with their nominated referents. Using this social network data, we estimated group-level normative influence by taking an average of referents' modern contraception use. We then explored associations between descriptive norms, injunctive norms, and network modern contraceptive use on individual modern contraceptive use, controlling for known confounders using logistic regression models. We also conducted sensitivity analyses to test a pattern of differential referent influence on individual modern contraceptive use. There was a positive association between pro-modern contraception descriptive and injunctive norms and individual modern contraception use (adjusted Odds Ratio (aOR) = 1.29, 95% confidence interval (CI) = 1.05-1.6, and aOR = 1.31, CI = 1.06-1.62, respectively). Network modern contraceptive use was associated with individual use in the bivariate model (aOR = 2.57, CI = 1.6-4.12), but not in the multivariable model (aOR = 1.67, CI = 0.98-2.87). When stratified by sex and marital status, network modern contraceptive use was associated with individual modern contraceptive use among female participants (aOR = 2.9, CI = 1.31-6.42), and unmarried female participants (aOR = 5.26, CI = 1.34-20.69), but not among males. No interactive effects between norms variables were detected. Sensitivity analyses with a different estimate of network modern contraceptive use showed similar results. Social norms are multilevel phenomena that influence youth modern contraceptive use, especially among young women in rural Kenya. Unmarried women with modern contraceptive users in their social network may feel less stigma to use contraception themselves. This may reflect gendered differences in norms and social influence effects for modern contraceptive use. Future research should investigate group-level normative influence in relation to family planning behaviors.

Laser Range Scanners for Enabling Zero-overhead WiFi-based Indoor Localization System

Robust and accurate indoor localization has been the goal of several research efforts over the past decade. Toward achieving this goal, WiFi fingerprinting-based indoor localization systems have been proposed. However, fingerprinting involves significant effort—especially when done at high density—and needs to be repeated with any change in the deployment area. While a number of recent systems have been introduced to reduce the calibration effort, these still trade overhead with accuracy. This article presents LiPhi++ , an accurate system for enabling fingerprinting-based indoor localization systems without the associated data collection overhead. This is achieved by leveraging the sensing capability of transportable laser range scanners to automatically label WiFi scans, which can subsequently be used to build (and maintain) a fingerprint database. As part of its design, LiPhi++ leverages this database to train a deep long short-term memory network utilizing the signal strength history from the detected access points. LiPhi++ also has provisions for handling practical deployment issues, including the noisy wireless environment, heterogeneous devices, among others. Evaluation of LiPhi++ using Android phones in two realistic testbeds shows that it can match the performance of manual fingerprinting techniques under the same deployment conditions without the overhead associated with the traditional fingerprinting process. In addition, LiPhi++ improves upon the median localization accuracy obtained from crowdsourcing-based and fingerprinting-based systems by 284% and 418%, respectively, when tested with data collected a few months later.
