Due to the extremely combustible nature of the gas, there is always the risk of gas leakage as a consequence of carelessness or failure of the regulating valve on the gas cylinder, which poses a significant risk. Gas-related fires are on the rise, which may be prevented by utilizing a gas leakage detection system, necessitating the creation of a microcontroller-based cooking gas detector. The use of a microcontroller allows for the creation of a highly precise and quick reaction time detecting system. The detector includes a MQ-6 LPG gas sensor, a PIC16F690 microcontroller, an LCD, a buzzer, and a number of LEDs to learn about the gas leak's condition. When a voltage signal is present from the MQ-6 sensor exceeds a specific threshold, the microcontroller detects the presence of a gas and sends an audiovisual alert. All peripherals are linked to the microcontroller through its pins, which are coded in the PIC assembly language. When the system was turned on, the microcontroller turned on a green LED to indicate that there was no gas leakage. A digital multimeter is used to monitor the sensor voltage signal when LPG gas is discharged. Whenever the voltage is less than 2.0V, the green light remains illuminated; when the voltage is more than 2.0V, the microcontroller blinks a red LED and sounds an alarm to indicate the presence of a gas. The alert can be recognized by pressing a button on the sensor. When the system was turned on, the microcontroller turned on a green LED to indicate that there was no gas leakage.

Sentiment analysis can systematically identify, extract, and scrutinise emotional states and subjective information in social media data. Exploring reactions and perceptions to response messaging is invaluable and proved especially useful for a pandemic response as it can demonstrate general population reaction to the pandemic and governments response actions. This can be further analysed to identify the gap between government response actions and communications and citizens' perceptions. In this paper, an analysis of Twitter data explores population reaction towards COVID-19 health messaging. A Natural Language Processing Python tool is known as TextBlob was used to discover general data sentiment. Data were divided into three sentiments and text extraction of health messages was conducted to explore subsequent tweets in predefined categories. Our findings show the outcome of Tweets analysis could help us to identify the general population concerns and their reactions to COVID-19 to give a better understanding of the situation to governments and support them in implementing appropriate policies.","PeriodicalId":272590,"journal":{"name":"2021 IEEE 12th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)","volume":"33 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":"131643593","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}

In such a connected world, one of the critical factors in maintaining the security of transmitted data is user authentication, which establishes confidence in the user identities presented to an information system. Over time, the definition of user authentication has not changed; however, a simple password is no longer the only factor used for authenticating a user. Two-factor Authentication (2FA) and Multi-factor Authentication (MFA) were proposed to provide a high level of security by adding more than one layer of authentication. For the most part, these layers of Authentication are based on knowledge, ownership, biometrics, and/or users' behaviors. This paper presents and analyzes authentication factors that are utilized to authenticate a user and prove his/her identity to a resource.","PeriodicalId":272590,"journal":{"name":"2021 IEEE 12th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)","volume":"6 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":"131649388","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}

The proposed integrated system architecture consists of an attached camera that communicates with the FPGA through HDMI interface. The deployed computer vision algorithm in the FPGA can capture video frames at the rate of 60 fps with the large image sizes of up to 1280×1024 pixels. It then identifies the object based on the specified color, removes noise via spatial filtering and calculates the centroid allowing the object to be tracked during motion. The proposed algorithm leverages a reduction method to minimize the FPGA area as well as power consumption by averaging values over a range of several pixels; thus logarithmically reduces the design size. Our implementation is parameterized to be made as accurate or small as an application requires, with minimal error. The proposed tracking system is implemented on a Xilinx ZYNQ-7000 series XC7Z010 FPGA housed on Xilinx Zybo development board. The utilization reports show for a selected reduction rate of 16, 86.5% reduction in Slice LUTs and 81.3% in Slice registers with the maximum error of 1.5% in centroid calculation.","PeriodicalId":272590,"journal":{"name":"2021 IEEE 12th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)","volume":"103 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":"133497640","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}

In the past years, one of the hot research issue in the context of ridesharing is to enhance trust. Such trust based ridesharing problem can be described as an optimization problem in which a large number of constraints must be satisfied. Due to complexity of this optimization problem, exact methods are limited and cannot be applied. Therefore, approximate methods are usually applied to find the solutions. This problem can be solved by evolutionary algorithms. The purpose of this study is to develop an algorithm for trust based ridesharing problems by applying neighborhood search in Differential Evolution approach. We compare the proposed algorithm with other competitive algorithms. The numerical results indicate that applying neighborhood search in Differential Evolution approach leads to a more efficient solution algorithm.","PeriodicalId":272590,"journal":{"name":"2021 IEEE 12th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)","volume":"35 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":"114476839","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}

The two PLLs only differ in voltage-controlled oscillator (VCO): current starved and LC VCOs. Using device degradation models and equations, their performances are investigated under the combined effects of soft breakdown, hot carrier injections, and negative bias temperature instability. It is observed in the current starved VCO that the gain reduces by 33.5%, the maximum frequency decreases from 1180 MHz to 1100 MHz, and the phase noise increases from −107.6 dBc/Hz to −103.5 dBc/Hz at 1 MHz offset frequency after 6 hours of stress. The varactor degradation in LC voltage-controlled oscillator causes a decrease in the mean capacitance, resulting in increased oscillation frequency. In addition, the phase noise increases from −120 dBc/Hz to −117.2 dBc/Hz at 1 MHz frequency.","PeriodicalId":272590,"journal":{"name":"2021 IEEE 12th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)","volume":"4 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":"114650076","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}

A crowd is formed at sporting, holiday, religious, or political events. Proper management of a crowd is one of the major duties for the civic agencies such as police and fire departments to maintain public order and safety. When such management is ill-prepared and poorly executed, it can result in chaotic situations with human injuries and fatalities as well as damage to public properties. Good crowd management requires a good modelling of crowd dynamics and devising strategies accordingly. This paper presents the modelling and simulations of crowd dynamics that resembles the actual crowd behaviours using the social force model. With the realistic crowd dynamics, different scenarios and crowd management strategies were tested for optimal crowd flows. Our framework can be used to test various scenarios of an event that attracts a large crowd and devise suitable strategies for the crowd management.","PeriodicalId":272590,"journal":{"name":"2021 IEEE 12th Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON)","volume":"48 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":"125123917","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}

Spectral graph theory may assist the study of network forensics by better understanding how a virus spreads throughout a networked system. This paper analyzes the spread of a virus throughout a computer network using actual data. The novelty is the calculation of various Laplacian matrices to observe the changes to the network, modeled as a graph resulting from the virus spread.

Recently, the advances in artificial neural network have led to varied high-performance single-shot detection algorithms. These algorithms are especially useful in real-time applications. Hence, in this paper, we present a study of various object detection algorithms towards pothole detection with its speed and accuracy.
