Ant Colony Systems, in particular, are inspiring. They commonly have drawn inspiration from the behaviors of real ants in nature in order to construct routes between the food sources and the nest. There are still gaps in alternative options for path decision in ant agents. Bellman's equation has been successfully used to solve path decision problems in machine learning. We proposed to investigate impact of a Bellman's equation inspired algorithm for path decision on stigmergic ant agent robotic devices. A design science research paradigm was used to design our research experiment in which a simulated environment was designed to simulate the behavior of ant agents when using a Bellman's equation inspired algorithm for path decision. We introduced a reward function to the orientation process of ant agents. Reward function rewards a decision made when an ant moves from one point to an adjacent cell. The Bellman's inspired algorithm for ant orientation led to convergence of ant agents even though there was reduced quality of convergence. Evaluation of results show that Bellman's equation can be used in path decision processes for ant agent robotic devices. Our results contributed to adding an alternative way of implementing path decision for ant agents. This will help in growing the knowledge around ant agents and finding better ways to implementing path decisions for ant agents.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122867439","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}

Examining human facial expressions, subject to the activities they carry out at certain times can help improve interactions between humans and computers especially in the era of a digitized society. Communication channels include vocal, body gestures, and facial expressions. Body gestures and facial expressions, as a means of communication, are known to be acquired either involuntarily or voluntarily to lay emphasis on emotions that may not be explicitly expressed via vocal means. Facial expressions are one of the common non-verbal visual cues used by humans in communicating emotions. Facial expressions as a channel to estimate emotions is useful in many applications such as e-learning, online marketing, and e-therapy. E-therapy is regarded as having a healthcare professional to provide mental health services via an electronic medium. There happens to be a range of challenges that could prompt therapy to be administered via electronic channels. This study explores the development of a tool that can facilitate the evaluation of a patient's emotion using their facial expressions during an e-therapy session. Further to evaluating facial expressions, there is a medium provided to estimate the expressions and generate a feedback that can be used by the therapist. Models for facial expression estimation and feedback generation uses deep learning and transfer learning techniques. The initial study was carried out using expression samples obtained from the KDEF and JAFFE databases. The results obtained show a 74.9% and 90.9% accuracy in facial expression classification of images from KDEF and JAFFE databases respectively.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131724560","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}

Phylogenomic tracking of the pandemic represents one of the ways to monitor its spread in real-time. However, effective phylogenomic monitoring is dependent on the generation and analysis of rich genomic datasets. In this study, we performed phylogenetic analysis on SARS-CoV-2 genome data for the African continent to illustrate the spread of the pandemic. Africa's contribution to the SARS-CoV-2 genome data stands at just under 2% of the global total, with only seven countries currently represented on the NCBI virus database, and 16 countries on the GISAID database, as of 10 August 2020. A large portion of the data (79%) in NCBI is from Egypt, while sequence data from South Africa (48%) dominates the GISAID collection. Although there exist a massive data gap in terms of geographic coverage and scale across both databases, the inferred phylogeny is consistent with Egypt having the first reported case of COVID-19 on the continent, with multiple independent infections in other parts of Africa. However, we identify significant incongruences in the timing of sampling and placement of sequence on the inferred phylogeny. We surmise that the source of incongruence is a probable discrepancy between sample collection and sequence generation, leading to phylogenetic placements that violate basic rule of molecular evolutionary progression. Consequently, we propose the rapid processing of samples destined for sequencing as soon as they are collected, as Africa gradually increases its SARS-CoV-2 genomic footprint. We also advocate for the release of SARS-CoV-2 genomic sequences to the public domain to facilitate quality research around the virus.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134071434","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 study proposes the use of smart locker systems that are opened by pin codes, mobile applications, mobile USSDs, or RFID tags. These lockers will be placed at secure centres in rural areas e.g. hospitals or police stations and be used for the collection of parcels. Currently, most rural areas are under-serviced by logistics service providers as they do not have good roads and address systems. Anchoring on the Unified Theory of Acceptance and Use of Technology (UTAUT), this paper analyses attributes that affect a customer's intention to accept and use smart locker systems as a last-mile delivery method. The study has 56 voluntary participants from Gqala village (Eastern Cape, South Africa) who were divided into focus groups for interviews to be conducted. The data collected was coded and themes were identified, of the themes identified the strongest six are presented in this paper as propositions. These results highlighted some critical determinants of technology acceptance and use that are not reflected in the UTAUT. This study then also presents a modification of the UTAUT which the enhanced unified theory of acceptance and use of technology (EUTAUT) is coined from.

However, their use for work purposes is largely becoming a common practice as most organisations rather prefer to find security countermeasures than miss out on the momentous benefits they provide. Since the weakest link in cybersecurity is the human element, organisations are increasingly looking for ways to upskill their employees so that they can be able to implement the necessary security safeguards. Yet, a concerning trend is that even individuals with a high-security self-efficacy sometimes fail to take the needed security actions. To better understand why this occurs, the present study proposes and validates psychological ownership as a possible boundary condition for explaining the security self-efficacy to security behaviour nexus in the mobile security context. Using an online survey with 214 respondents, this study showed that both the direct and indirect effects of security self-efficacy on mobile device security behaviour were moderated by psychological ownership such that the effects were more pronounced when psychological ownership was high than when it was low. The paper culminates with a discussion of the implications for theory and practice.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121233062","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}

Although there's effort in urban areas by municipalities to purify and monitor the water used for consumption, the existing mechanism used is not as automated and reliable, even worse in rural areas no proper care is taken or no genuine mechanisms put in place. In this paper, Water Quality with Notifications System is presented to better the lives of the people by providing an easy and simple mechanism to know the water quality stored in the reservoir. It holds different sensors for getting water quality parameters namely PH Sensor, Nitrate Sensor, Turbidity Sensor, Water Level Detection Sensor. The system gets water parameters from the sensors through Raspberry Pi. It is a portable system and no monitoring authority is required at the water source 24 hours a day.

Intersatellite optical wireless communication (ISO WC) is a unique modus operandi for the communication between satellites either they are in the same orbit or not using optical wireless communication as a medium. ISOWC as a system has some merits among are low power consumption, unlicensed Spectrum, huge bandwidth, high data rate, low-priced alternative to microwave satellite systems and immune to electromagnetic interference. In designing an efficient ISOWC link (ISOWCL), the choice of choosing an optical wavelength with an appropriate modulation formats that will enhance the performance the system become paramount. Previous studies have limited their work to two modulation formats and wavelengths. This cannot be used as a yard stick to for efficient design of an ISOWCL. In this research work, we evaluated the performance of ISOWCL considering multiple wavelength and diverse modulation formats. Bit error rate was used to evaluate the performance of the link. The result obtained showed that non-Return to zero performed better than all other modulation at all wavelengths while hyper secant had the worst performance. In all the wavelength considered, 1650 nm performed better than all other wavelength which is not mentioned in previous researches. The result will assist to develop an ISOWC link with good quality of service for inter-satellite.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"339 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122750369","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}

Real world applications are often streaming and their measurements are often sampled after an extended period of time thereby giving rise to the formation of a time series. Measurement devices assigned to measure nonstationary quantities are subject to failure. When a failure occurs, the process of approximating missing values becomes difficulty. The process of approximating missing values in such dynamic environments is further exacerbated by the chaotic and unpredictable nature of the evolving data. Typical examples include stock market, network intrusion detection systems and seismic waves. To estimate missing values with traditional statistical methods can lead to bias when applied to environments that evolve with time. This paper introduces an ensemble of regressors approach to approximate missing data in online nonstationary data. The approach learns new concepts incrementally and the current learnt concept is then used to approximate the missing values.","PeriodicalId":349926,"journal":{"name":"2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129338442","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}
