2. PATIENT HEARTBEAT AND TEMPERATURE MONITOR

30 Student Researchers

BACKGROUND

Heart beat rate means the number of heartbeats per unit time, usually expressed as beats per minute (bpm).

60. DESIGN AND CONSTRUCTION OF A SINGLE PHASE AUTO-TRANSFORMER OF RATING IKVA, 240V/110, 80 12V, 6V

30 Student Researchers

ABSTRACT

This project work-up deals on the design and construction of a single phase step down nations fermor, with raking IKVA, 240V/11OV, 80V 12U, 6V. It is a multi-circuit transformer that has one input as the primary and tappins to produce the output (secondary). It is considered as a single coil in series with the supply and a common coil to the head. It is experimentally done using flat metal shocks of cast steel to form the &...

61. RELIABILITY AND PROTECTION IN DISTRIBUTION POWER SYSTEM CONSIDERING CUSTOMER BASED INDICES

30 Student Researchers Quantitative

BACKGROUND OF THE STUDY

Electricity is a component that cannot be overlooked in any contemporary economy. It is essential for the expansion of a nation's economy and its overall development that the nation have access to an affordable and dependable source of electricity (Chidanandappa et al., 2015). Therefore, electric power utilities all over the world work hard to satisfy consumer expectations in the most cost-effective manner while still pro...

62. DESIGN AND IMPLEMENTATION OF ARDUINO-BASED COUNTER SYSTEM

30 Educators Qualitative

Background of the study

As physical and time-consuming operations are digitalized, the globe is rapidly becoming a digital hub. In the 1990s, people utilised primitive ways to count visits by manually counting them or using a manual tally counter. However, with ongoing innovations and increased requirements and obstacles, such as the covid-19 epidemic, which necessitated social distance and crowd management, load control for str...

63. AN EXAMINATION OF IMPROVED FAULT LOCATION ON POWER SYSTEM TRANSIMMISION LINES USING FUZZY LOGIC APPROACH

30 Student Researchers Quantitative

​​​​​​​BACKGROUND

The reliable operation of large power systems with small stability margin is highly dependent on systems and protection devices. The application of microprocessor based (numeric) relaying protection has improved performance over time but, this has not led to a major impact on speed, sensitivity, and selectivity of primary protective relays. However decision making based on elements of artificial intelligence (AI) can, in my view, lead to a major im...

64. ANALYTICAL DESIGN AND CONSTRUCTION OF AUTOMATIC SOLAR STREET LIGHT

30 Student Researchers Quantitative

INTRODUCTION   

Since the discovery of electrical energy for illumination, it is evident that human interaction is required to operate the switch, either off when not in use or ONM when needed. Because of this reason, as well as a lack of electricity supply, there has been a pressing need to develop a highly efficient and effective method of generating electricity for the purpose of illumination known as solar energy (Craig, 2016). According to Oke, Adigun...
