Abstract: Water distribution systems mostly involve laying of pipes with the digging of trenches to lay down water pipes as a significant activity. During rainy seasons, trenches tend to fill-up with rainwater before the said pipes could be laid. This poses a danger to workers and residents due to potential landslides. This paper presents the design and simulation of an autonomous anti-rain construction site cover system (AARCSCS), which automates the process of covering a trench or excavati...
Spiders are primarily beneficial and their activities should be encouraged in the garden. Pesticide control is difficult and rarely necessary. The best approach to controlling spiders in and around the home is to remove hiding spots for secretive spiders such as black windows and regularly clean webs off the house with brushes and vacuums. Maintenance of a building is the work undertaken in order to keep or restore every part of a building, every facilities or machinery to an acceptable stan...
ABSTRACT This project work is designed mainly for the preservation of foodstuffs, storing of medicines and the cooling of water and drinking fluids in our homes and offices. In the choice of the necessary parameters for the design, Dichlorodifluoromethane, Freone (R12) is used as the refrigerant. An evaporating pressure of 1.237 bar and condensing pressure of 13.66 bar and corresponding temperatures of -25°c and 55°c was considered and the volume of the inside of the refrigerator was fixed...
Abstract: In this work, we study the soft vector space introduced by A. Sezgin Sezer et al. in 2014. We define normal soft sub vector space, normalistic soft vector space, trivial normalistic soft vector space and whole normalistic soft vector space. We also present the properties of operations such as union (∪ ), intersection (∩ ), restricted union (∪𝑅), extended intersection (∩𝐸), restricted difference (~𝑅), AND (⋀ ) and OR (⋁ ) operations and investigate their inter-re...
INTRODUCTION A program in a non-structured language usually consists of sequentially ordered commands, or statements, usually one in each line. The lines are usually numbered or may have labels: this allows the flow of execution to jump to any line in the program. Non-structured programming introduces basic control flow concepts such as loops, branches and jumps. Although there is no concept of procedures in the non-structured paradigm[citation needed], subroutines are allowed. Unlike a proc...
ABSTRACT This paper discusses the meaning of the terms Expression of interest, invitation for bids and request for tenders. These terms are often used and hence a clear understanding of what they mean is cardinal to everyone whose day to day vocabulary involves these terms
Abstract Construction projects are known to experience time delays due to various reasons. The aim of this study is to find out if the material management approach used on building projects has a relationship with the scheduled completion time of the projects. Various literatures were reviewed so as to identify the different material management techniques available and classification of time overrun. The study was carried out on building projects situated in Lagos and simple random sampling t...
