ABSTRACT The steam boiler is to control specification problem, to illustrate how the evolving algebra approach to the specification and the verification of complex system can be exploited for a reliable and well-documented development of executable but formally inspectable and systematically modifiable code. A hierarch of stepwise defined abstract machine model in developed, the ground version of which can be checked for whether it faithfully reflects the informally given problem. The sequen...
ABSTRACT In this research, an hydrological modelling tool, soil and water assessment tool (SWAT) used to investigate the spatial and temporal variation of sediment yield in a watershed. The model was run for 31years using spatial data such as Digital Elevation Model, soil map, land use and precipitation, wind and solar radiation. The results showed that the maximum value of surface Runoff was estimated as 19100.034mm in the year 2005 while the minimum surface Runoff was 1000.671mm in the yea...

ABSTRACT In present time due to increase in number of kidnapping and road accident cases, parent always worry about their children. This paper proposes a SMS based solution to aid parent to track their children location in real time. The proposed system takes the advantage of the location services provided by module kit which carry by the child in their school bag. It allows parent to get their child location on a real time map by the geographical co-ordinates which send by module kit. Infor...
ABSTRACT The research deals with estimating some mechanical properties of rock from in-situ rebound value in Oreke open pit quarry ,N-Type Schmidt rebound hammer data were collected from Oreke open pit .the data were collected with the view to ascertain the suitability of Schmidt hammer for quick ,cheap and less cumber some estimation of the uniaxial compressive strength of marble .The data collection was strictly carried out by ASTM and suggested equation by different authors.

ABSTRACT In the face of a possible scarcity of natural aggregates in the future in line with sustainable construction, this research investigates the feasibility of the use of recycled coarse aggregates as an alternative to natural coarse aggregates in structural concrete. The recycled coarse aggregate used in the research was processed from waste concrete. The percentage of recycled coarse aggregates by weight of all in aggregates in the test mixes were 0%, 5% 10% 20% and 30 % respectivel...

ABSTRACT Maintenance is the technical exercise that is usually carries out on machines to restore a component going to fail or failed component back to it design function in the machine. The role of maintenance in machine work shop can not be over emphasized, because without it, many causality that would have been recorded in a workshop would have been much, most especially in some machine workshop that deal with the use of hazardous chemical in their production process of materials. e.g petr...
CHAPTER ONE 1.1 INTRODUCTION For quite sometimes, organization have been reaping low profits, the reason for this is not for fetch. They failed to appreciate the significance of an effective communication in an organization, which is the tool or instrument of efficient and effective operation in an organization. However, Communication is a crucial element to every organization. Communication is an organization is a primary binder, it binds every department together...
ABSTRACT Refrigeration is term used to denote the maintenance of a body at a temperature lower than that of its surroundings. The applications of refrigeration are many and varied. In addition to the common applications of refrigerationin the manufacture of ice, in the preservation of foods, in air-conditioning filed, and in the creation of skating rinks, the refrigeration effect is also used in the presentation of blood plasma, in the low-temperature treatment of metals and in the liquefact...
ABSTRACT Security of life and property cannot be over emphasized. Human beings need privacy in their various homes and offices which necessitate the need for doors among another security services. To has been a major challenges for the people to have door of high quality and that are also durable at affordable prices by an average Nigerian. This project was done purposely to fabricate a metal panel door of high quality capable of giving maximum securities to life and properties at affordable...
ABSTRACT The single wheel driven boom sprayer was developed, fabricated and evaluated for its performance at the department of Agricultural and Bio-environmental engineering workshop, Kwara state polytechnic, Ilorin. The spraying performance was carried out at spraying height of 0.5m, 0.6m and 0.7m respectively. The theoretical field capacity CT, the effective field capacity CE and Field efficiency (ŋ) at spraying height of 0.5m are 0.285ha/hr , 0.165ha/hr and 58%, while at spraying h...
ABSTRACT This project is on the design and fabrication of deep freezer for the preservation of items/products and making the items to cool. The project is able to develop a simple efficient economical and environmental friendly refrigeration system (A freezer) towards better technological advancement in Nigeria. This project modifies the existing refrigeration system with the use of R-600a which is ozone friendly, and non-contaminant like previous refrigerant of the hydrofluoric-carbon, HFC ...
ABSTRACT This project is aimed at explaining the Design and construction of a digital wall clock with a calendar. It give report on how we can achieve this aim and the primary objective of this work is to bring a vibrant digital clock display to everyone located within the vicinity where the clock is being installed, and the importance of clock is to tell time and date, so you can meet up with events and assignments, these are just few importance of CLOCK. In developing co...
