An Empirical analysis on the factors influences the wastage of Banana and Cherries

Tue, 07 Sep 2021 00:00:00 +0000

The research highlights main critical points related to controlling the wastage of bananas and cherries. Above all, there are: the limited shelf-life, packaging, delivery time sensor, and costs that can influence the wastage. However, the methodological framework suggests that Packaging under the influence of efficient sensors and cost forces the supply chain to be shaped as both responsive to the market (by reducing the wastage) as well as efficient. The study uses a theory-building approach that adopted a qualitative research method. The research strategy includes preliminary desk research followed by qualitative research composed of interviews with experts in the field. All interviews were constructed using open-ended questions either executed face to face or through phone calls. The questionnaire was also distributed among different retailers, wholesalers, and manufacturers.

Impact of Digital Technology and the Need for Periodical Review of Educational Curriculum in Nigeria Tertiary Institutions

Najeem Olawale Adelakun — Mon, 11 Oct 2021 00:00:00 +0000

Effective curriculum is a key determining factor to the growth of the education system in any meaningful societies or nations. It is worthy of note that technology keeps evolving which prompts the need for concurrent review of the curriculum. Presently, there are still outdated topics that ought to have been phased out from the curriculum, it is alarming that some tertiary institutions are still using the old curriculum while those that have adopted the new curriculum have not fully implemented the full content due to the lack of adequate equipment or unavailability of trained personnel. This paper assessed the present state of the Nigerian curriculum, and for better output performance, there should be a recurrent review of the curriculum at most every three years to keep abreast of modern technology. Hence, it was recommended that there should be a recurrent review of the curriculum to meet the trend of economic needs of the nation, training and retraining of lecturers, establishing and equipping all laboratories with modern equipment. Most importantly, those from industries should be part of the team for the formulation of the curriculum to produce competent and qualified graduates.

Opportunistic Cooperative Relaying Protocol for UAV-assisted Flying Adhoc Network

Muhammad Nauman Bashir, Kamaludin Mohamad Yusof — Fri, 29 Oct 2021 00:00:00 +0000

A tremendous rise in the use of Unmanned Aerial Vehicles (UAVs) in wireless communication is recently observed. Due to the useful features of UAVs, a new era of over-the-head wireless communication is finding its space at a rapid pace. A range of civilian and military applications is being tested using such UAV-assisted Flying Ad-hoc Networks. In such networks, the quality of communication is usually affected due to fading on channels and limited resources of the UAVs. In this work, we study the outage performance of dual-hop network over Rayleigh fading air-to-ground channels between source UAV and destination Ground Control Station and a group of intermediate UAV aerial relays. We focus on spatial diversity using cooperative relaying through relaying UAVs working in a cooperative manner to support the communication using maximum ratio combining at the destination. The best relay may be selected based on channel state information in terms of signal-to-noise ratio to make the system resource efficient. UAVs are assumed to work in Amplify and Forward mode in Half Duplexed downlink communication scenarios while deriving the closed-form expression for the outage probability. Numerical results are validated using Monte Carlo Simulations to study the impact of various system parameters on performance. The results of proposed non-buffer aided scheme is compared with compulsory direct-only communication. The impact of number of intermediate relays on dual hop links, symmetric and asymmetric channels is studied. The results are compared by changing the data rate and SNR of the links. The results show that cooperative relaying decreases the outage probability. More relays in cooperation, improve the system performance but at the cost of the network increased resources.

Heat Stroke Prevention Wearable Based in Internet of Things (IOT)

Thu, 25 Nov 2021 00:00:00 +0000

This study is to introduce the development of a new alerting system for parents about children exposure to risk related to heat stroke. The smart heat stroke detector was created with the intention of measuring the internal temperature of the human body, which is closely linked to cases of heat stroke. Heat stroke is caused by the body overheating, which usually occurs as a result of being exposed to or exerting physical effort in high temperatures. Usually, the foremost genuine of warm damage and warm stroke and can happen in case the body temperature rises to 40 °C (104 F) or higher. The methodology adopted for this sub project is implementing the Internet of Things (IoT) system and embedding the interface hardware into smartphone system software. This device connects to the network provider to display information the device gathers from the environment through sensors. A gateway enables cloud services to be accessed by devices that are not directly linked to the Internet. The results obtained undeniably implicit that the body temperature increased significantly when children too expose to the environment. Thus, the importance of this device evaluated through lecturers, parents and students perspectives was 90% respectively. The resulting system was also low in power and cost, non-invasive, and provided real time monitoring. It is also easy to use and provides accurate measurements. In conclusion, the study of this proposal will assist in the reduction of heatstroke among potential children in the near future in Malaysia.

ALICE Pattern Matching Based Chatbot for Natural Language Communication: System Development and Testing

Wed, 05 Jan 2022 00:00:00 +0000

The simulation of human processes using Artificial Intelligence (AI) features is finding place in various fields including the e-learning environment. Chatbot system using text and voice, recognizing images, analyzing the sentiments, and generating natural language is latest utility based on AI concepts. The chatbot systems are becoming more common due to their benefits as a support mechanism helping human beings in their day to day tasks. This project aimed at developing and testing a chatbot system to communicate with the education sector users using natural language through android based application creating a smart education environment. The project developed an online chatting platform using Artificial Linguistic Internet Computer Entity (ALICE) Pattern Matching techniques where students could communicate related to their learning activities such as submission deadline of the reports and assignments, student’s information, co-curricular and extracurricular activities. The system design uses a Raspberry Pi 3 which works as Transmission Control Protocol (TCP) server and uses three different types of pattern matching techniques which are keyword detection, symbolic reduction, and synonyms resolution. An android user interface application is also designed which works as TCP client. The system design uses a database for student information system in the Python server. The obtained results are in voice and text format from the android user interface application and are displayed on Python Interpreter. The developed project system can enhance the student engagement in learning activities. This system can also help teachers in saving their time and to support them to utilize their class timings for other co-curricular activities like synchronous and asynchronous activities to support active learning and flipped learning. The proposed system has the potential to test and analyze various factors as use of technology, student learning including impact of student engagements in their learning activities.
