Abstract: The Operating Theater (OT) is one of the most critical and expensive hospital resources since a high percentage of hospitalizations are due to surgery. The main objectives are to perform the operation at the right time without incurring excessive waiting times and to optimize the use of medical resources in order to achieve maximum profitability. With the unpredictability and disruptions ingrained in the process (OT), its management is a very complex procedure. Management problems in the (OT) have been identified with well-known problems in the field of manufacturing or transport. This prompted us to look for a model used in industrial applications that would allow us to solve the problems of (OT) process as a whole..........

Abstract: Construction Industry is a high risk Industry and involves considerable investment. There are plethora of risks and uncertainty in the construction industry due to which the actual cost exceeds the budgeted amount. This places strain on the client and in the process of completion of project, keeps on borrowing the funds finally leading to insolvency of the client in most of the projects. Hence, it is very important to have a proper cost estimation of the project taking the identify and foreseeable risks and uncertainties into This paper has analysed the cost of construction project by using the Monte Carlo Simulation. The research examines the effect of correlation between the various project costs by using Monte Carlo Simulation.

Abstract: Numerical modelling for predictive maintenance deals with the capturing and recording of process variables during operational phasesof multi-machines configurations intended for maintenance driven decisions. This imply that the design phase of this lean manufacturing strategy draws from the anticipated process conditions and logics of operation of the assembly. In order to investigate the possibility of this proposition, the study conducted twocombinatorial simulationsfor both series and parallel multi-machines configuration. This simulation was done in order to support the proposition of the application of numerical modelling in the area of predictive maintenance. The results of the simulations were tabulated and process sequence graphs were generated to indicate...........

Abstract: The phenomenon of increasing population and high building density causes limited interaction space in residential areas so that the road network functions as a place to carry out activities and endanger the safety of residents due to high traffic activities. The aims of this discussion are 1) to explain the condition of the site of residential buildings and environmental roads to the comfort and safety of residents; 2) explain the occupants' daily activities in the use of roads as a public space for traffic activities on the road; 3) develop the concept of sustainable roads in dense settlements. The research design uses a qualitative and quantitative descriptive approach with the research location survey stage, which aims to obtain the accurate data and information to find out the concept of roads needed in dense residential areas...........

Abstract: This study investigated the feasibility of saving the energy required in a building right from its design stage. The School of Engineering and Engineering Technology (SEET) building of the Federal University of Technology, Akure, Ondo State in Nigeria was used for the study. The indoor temperature and the illuminance of selected facilities within the building were measured and recorded, over a month; when the air conditioning and lighting systems were respectively switch off. Subsequently, the air conditioning (A/C) and the lighting requirements of the investigated facilities were estimated using existing formulae and design charts assembled for the purpose. It was ensured that the estimation took into consideration the ergonomics requirement of the investigated facilities to provide the needed comfort..........

Abstract: Construction as well as performance of an unmanned underwater vehicle is discussed in this paper. The unmanned underwater vehicle is developed to exploit the underwater environment. The body is 0.56 m long and 0.254 m diameter torpedo shaped. Different components of the vehicle are made by aluminum to reduce the weight. Four submersible pumps are used in two ballast tanks for water intake and exert through two solenoid valves. One propeller is used and a rudder is set behind the propeller. The thrust force generated by the propeller gives forward motion to the vehicle. In the present research, an UUV was developed and experiment was conducted. During experiment, major problems were water leakage and system stability. Very little amount of water enters into the pressure hull through different joints. To avoid this situation, glue is used in different joints and tape is wrapped at the outer surface of the body. In this study it is found that this small flat form can be used in various purposes like underwater research, military and civil works.

Abstract: Abstract: Beams are structural elements that primarily resist loads applied laterally by bending. They exhibit dynamic behaviours and hence the need to predict their dynamic characteristics for proper structural design. In the cause of some disturbances, beams start to vibrate which may result to some shear deformation on the fundamental frequency. Analysis of shearing effects on beams resulting from vibration is necessary in order to know how the member behaves. With this knowledge one can predict and avoid structural element from failure. Hence, this paper investigates shearing effects on free transverse vibration of beams. Classical method was adopted to determine the natural frequencies of beams with...........

Abstract: Reinforced concrete (RC) shear walls are considered to be one of the most major elements in the lateral force resisting systems. The existence of openings in RC shear walls becomes essential in some cases that relate basically to architectural or mechanical requirementsalthough they are not preferred to be constructed from the structural point of view. In this current work,massive numbers of numerical models are conducted using the well-known finite element software (ANSYS) for achieving an obviousconclusion about the influence of positions and dimensions of openings on the nonlinear behavior of shear walls under lateral monotonic loads. Furthermore,the efficiency of a proposed configuration of CFRP strips in retrofitting these RC walls with openings is investigated.
