From this it was concluded that cyber security and cyber-attack is best defined and prevented based on the field of research. This paper review 27 articles on cyber security and cybercrimes and it showed that cyber security is a complex task that relies on domain knowledge an...
A smart grid is an intervention technology for the massive energy demand of the world today. It combines cyber-physical technologies, information communication technology, and electrical power networks from the generating company stations to the end-users while ensuring bidirectional communication among the actors. The smart grid is a complex growing technology that is yet to reach its maturity state. This paper seeks to examine the literature on the state of the art of smart grid technology ...
The uncertainty associated with modelling and performance of solar photovoltaic systems could be easily and efficiently solved by using Maximum power point techniques. During the past decade of 2010 to 2021, the classification of techniques based on intelligent, non- intelligent and their hybrid models are found as potential techniques for detecting the maximum power point of a photovoltaic system. In addition, for this decade there is no extensive and comprehensive review on applicability of...
The recent developments in computational science and smart metering have led to a gradual replacement of the traditional load forecasting methods by artificial intelligent (AI) technology. The smart meters for residential buildings have become available on the market, and since then, various studies on load forecasting have been published. Contingency planning, load shedding, management strategies and commercialization strategies are all influenced by load forecasts. Predicting a lower load t...
ABSTRACT The study was conducted of the Improvement on concurrency control in a distributed database. The objectives of the study are to ensure consistent and correct transaction, efficient data collection and management and recoverability of data in a distributed database. The Mysql relational database was employed in collecting data for concurrency control protocols. The Unified Modeling Language (UML) was used in creating the use case, sequence diagram, class diagram and contract for the...
ABSTRACT The IEEE 802.11 Wireless Local Area Network (WLAN) standard was able to ease the communication difficulty by providing mobility and low cost of system deployment for its users. On the other hand, the WLAN has difficulty in meeting the optimum Quality of Service (QoS)demand for data applications. Consequently, a later variant of the amendment standard, IEEE 802.11n, came with improvement strategies. The introduction of frame aggregation, block acknowledgment and reverse direction pr...
ABSTRACT Web-based health management system for National Health Insurance Scheme is considered in this project work as an online information storage and retrieval internet portal where the stakeholders registered and participating in the National Health Insurance Scheme of the federal ministry of Health will be able to access relevant information regarding NHIS. The Internet portal will also be useful to prospective or intending participants who want to key into the programme. The stakeholder...
A CMOS biosensor with a folded floating-gate is created to detect charged biochemical molecules. It contains a FET, a control-gate and a sensing area. The floating-gate spans the whole device, allowing the sensing area to be placed on top of the FET, resulting in a decrease of the device's total area. The device is sensitive to the polarity and quantity of charged poly amino acids and could be used for electronic recognition of temporal and spatial migration of charges, such as in biological ...

A CMOS biosensor with a folded floating-gate is created for the detection of charged biochemical molecules. It is made up of a field-effect transistor with a floating-gate, a control-gate, and a sensing area. The molecules on the sensing area result in a voltage being induced on the floating-gate and a shift in the threshold characteristics. The floating-gate spans the entire device, which allows for the sensing area to be placed above the FET. This reduces the total device area. The device d...

An open microfluidic system has been developed to dispense and manipulate individual droplets on plastic sheets. Superhydrophobic material is applied to the surface of obtainable plastic sheets by spraying, then hydrophilic symbols are printed with an inkjet printer. The plastic sheets are connected to a two-axis tilting platform driven by stepper motors, which produces mechanical agitation enabling droplet transport. The system has been demonstrated to carry out various droplet operations, s...
This paper presents a remote monitoring tool for the objective measurement of behavioral indicators that can help in assessing the health and welfare of pigs in precision swine production. The multiparameter electronic sensor board can measure posture, gait, vocalization, and external temperature, and has been characterized through laboratory measurements and animal tests. Machine learning algorithms and decision support tools can be implemented to detect animal lameness, lethargy, pain, inju...
Electronic sensors to monitor pig behavior in farms.
ABSTRACT With recent advances in wireless technology, users of wireless network now expect quality of service and performance comparable to what is available in fixed networks. The IEEE 802.11e Medium Access Control (MAC) is an emerging supplement to the IEEE 802.11 Wireless Local Area Network (WLAN) standard that supports Quality-of-Service (QoS) requirements of both data and real-time applications. The IEEE802.11e MAC is based on both centrally-controlled and contention-based channel acce...
