The country has been having security challenges such as Insurgency, Arm banditry, Cattle rustling, Kidnapping, Political thugs, among others which leads to loss of lives and properties. The most occurring and challenging is the insurgencies that spread into many parts (Borno, Adamawa, Yobe etc) of the country. It has been a quite challenge to the security forces to track down and/or to prevent any insurgency before it occurs. This proposal tends to address these challenges by analysing the phone conversations through telecommunication networks to prevent the attack before it occurs. The analyser engine is to be developed which processes the most common spoken languages (English, Hausa, Yaruba, and Igbo) in the country and passes it to inference engine for decision making. The inference engine qualifies the processed conversions as either threats or not. If found to be suspected, a notification will be sent to the security forces to investigate and/or prevent.","PeriodicalId":228657,"journal":{"name":"2019 2nd International Conference of the IEEE Nigeria Computer Chapter (NigeriaComputConf)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133244730","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}

Blockchain can be regarded as a revolutionized distributed ledger technology which uses temper proof database in conjunction with consensus algorithms and cryptography. On the other hand, corruption has been a major problem in developing countries like Nigeria that bedevils their progress and development. In this paper, we investigate corrupt practices in developing countries with Nigeria as a case study. We study some blockchain use cases in some countries like Estonia and Georgia. We propose a blockchain framework to curb corrupt practices related to public funds embezzlement as the biggest corruption act. All transactions made by government agencies are stored in the blockchain shared by anti-corruption agencies, police, judiciaries and other related offices at the same time. We also propose the blockchain architecture and consensus suitable for the framework. Blockchain technology is immune to the influence of central authorities and intermediaries. It is secure against tempering and provides transparency and auditability. Hence using blockchain technology will help to tackle corrupt practices for betterment of developing countries such as Nigeria.","PeriodicalId":228657,"journal":{"name":"2019 2nd International Conference of the IEEE Nigeria Computer Chapter (NigeriaComputConf)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123916711","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 use of cables for hosting of payload can lead to natural swaying which makes it difficult to perform alignment, fine positioning as well as detrimental to safe and efficient operations. This paper presents a particle swarm optimization (PSO) based linear quadratic regulator (LQR) controller; for position and sway control of a double pendulum crane system. The major problem of designing an LQR controller is that, the Q and R parameter are obtained by trial and error which is quiet laborious. This paper optimized Q and R parameters by using PSO algorithm to obtain the best or optimal results. Simulation studies were carried out on the double pendulum nonlinear crane model which is created in MATLAB/Simulink environment. The simulation results show the effectiveness of the proposed controller in terms of reducing the trolley position percentage overshoot, hook oscillation and payload oscillation by 65%, 89.8% and 88.6% respectively.","PeriodicalId":228657,"journal":{"name":"2019 2nd International Conference of the IEEE Nigeria Computer Chapter (NigeriaComputConf)","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123059875","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}

To achieve this, extensively power steering systems have been employed today. This has been as a result of the increase in the front axle loads of vehicles, making it require more power to turn its wheels. In addition, there is a need for vehicles with more responsive steering properties. As a result, the quest for higher efficiency of the system necessitates the need for a more flexible and efficacious system. Electric Power-Assisted Steering (EPAS) systems can serve as alternatives to hydraulic power-assisted steering systems. The EPAS system offered the desired flexibility, engine and space efficiency. In addition, no pollution is emitted to the environment because of the omission of all hydraulic components. However, it has issues with system inertia and vehicle stability. Therefore, the requirement for vehicle steering stability becomes strict. As such, the focus of this paper is to give an overview of the EPAS system, its different configurations and subsystems, in addition to prospects and challenges of adopting the technology in vehicles.","PeriodicalId":228657,"journal":{"name":"2019 2nd International Conference of the IEEE Nigeria Computer Chapter (NigeriaComputConf)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115766457","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}

Hence, this paper carries out the usability and accessibility evaluation of the four main Nigeria mobile network operators’ websites. The websites tested are: www.mtnonline.com, www.gloworld.com, www.ng.airtel.com, and www.9mobile.com.ng. Four online automated tools were used which are: Mobile SEO, WAVE, TAW and Achecker. User testing was also conducted in a controlled environment with forty participants who were given five tasks to perform on the websites. The activities of the participants were recorded using Camtasia studio to get the total time taken to complete the task. Questionnaire for Interaction Satisfaction (QUIS) was used to get users feedback on the tested websites. The QUIS was designed based on five categories with each category dealing with an aspect of usability. The results show that the overall usability level of MTN was the best among the four. This was followed by GLO, 9mobile and Airtel respectively. From the results obtained, it is recommended that the web designers of the mobile network operators compare their website design with web content accessibility guideline (WCAG 2.0) to make sure the different categories of subscribers are satisfied with the features and services provided by the websites.","PeriodicalId":228657,"journal":{"name":"2019 2nd International Conference of the IEEE Nigeria Computer Chapter (NigeriaComputConf)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131113050","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 IEEE added mobility characteristics which made batterylife of Mobile Station (MS) a critical challenge, since MS are battery powered with an impose rechargeable life. An Efficient Battery Lifetime Aware Power Saving Scheme was proposed. The Scheme minimizes frequent transition of MS in order-to reduce power consumption but increases average response delay due to a longer sleep interval used. Thus, a Delay Aware Power Saving Scheme (DAPSS) Based on Traffic Load is proposed to reduce the excessive response delay. The Scheme introduces a modified minimum and maximum sleep interval in order to reduce the longer sleep time of a MS, and dynamically tunes the sleep parameters more appropriately according to the traffic load. It employed a delay aware algorithm to save power. The Scheme was evaluated using discrete event simulator, the results showed that the proposed DAPSS achieves superior performance compared to the existing Scheme in terms of the average power consumption and response delay.","PeriodicalId":228657,"journal":{"name":"2019 2nd International Conference of the IEEE Nigeria Computer Chapter (NigeriaComputConf)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134148409","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}
