EFFECT OF INVENTORY MANAGEMENT ON PROFITABILITY OF CEMENT MANUFACTURING COMPANIES IN NIGERIA

The rapid growth in technology has aided tremendous innovations which have ensured that man’s life is invigorated. It has elevated man’s effort towards achieving his goals easily. In the past, there are different ways of knowing or measuring time which include the use of the people’s shadow, position of the sun, and cock crows, but all these ways are not accurate and reliable but boring and tedious; and that leads to the introduction of clock. Analog clock was first introduced and this type of clock displays numerical values by physical variables. This analog type of clock does not solve the problems of accuracy and reliability and that led to the invention of digital clock. Digital clock displays a numeric representation of time with discrete or digital display (numerals or other symbols) as opposed to an analog clock where time is indicated by the positions of rotating hands. Digital clocks typically use the 50 or 60Hertz oscillation as a quartz clock to keep time. Digital clock displays the hour of day mostly in 24-hour and 12-hour format with AM or PM indicator, it also uses an LCD or LED display time. In this project a digital clock is developed with an LCD screen for the display of second, minute and hour. 1.2 Problem Statement Most digital clocks run consume power and drain battery. In addition, most digital clocks do not have backup battery to enable them keep accurate time and allow operations such as triggering alarm, even when the main battery dies. This is the need for a digital clock with backup battery. 1.3 Aim and Objectives The major aim of this project is to design and implement a real time digital clock which will display minutes, hours of the day with backup battery. Other specific objectives include: a.
