Subsea processing technologies such as boosting, separation, water re-injection and compression has been used in other oilfields but alien to West Africa. The technologies can increase oil recovery, extend the field life, and reduce topside equipment requirements. In this study Subsea, compression was adopted to model a typical field in the Niger Delta region whose data was collected and inputted into Flow ManagerTM Software that generated values for production and cost analyses. Though, there are many relevant field parameters but this study focuses mainly on the production profile of gas produced using subsea compression as against natural reservoir pressure. From the results, the field could produce 28,371,557Sm3/hr using natural reservoir pressure for the field life. Introducing 2-compressors at intervals increased the production to 32,050,438 Sm3/hr, hence extending the production plateau by 7-years with 13% oil recovery increase. Also, the cost analysis showed a $115.4m profit after subsea compression integration in this West African field.

A study on the evaluation of Avocado (Persea Americana L.)seed (AS), and African pear (Dacryodes Edulis L.)seed (APS) and Apricot (Prunus Armeniaca L.)kernel (AK), as vegetable based cutting fluids (VBCFs) in the turning of Ф25mm AISI 1020 Steel with high speed steel (HSS) cutting tool was carried out. The turning was performed at varied spindle speeds of 90, 125, 180rpm at constant 0.5mm/rev feed rate and 2mm cutting depth. The cutting fluids were fed to the tribo-interface by gravity. The surface temperature, surface roughness and chip thickness measured in the turning operations using the different VBCFs formulated were compared with those from commercial cutting fluids (CCF). The results showed that increase in speed decreased the surface roughness of AISI 1020 steel; and the least roughness-value was obtained at 180 rpm for AK oil-based fluids. The VBCFs of different formulations all showed good lubricity properties which compared favorably with the CCFs. The VBCFs formulation that showed the best tribological surface cooling characteristics, and lowest roughness and lowest chip thickness formation was Apricot Kernel Oil Cutting fluids (AKOF), even better than the CCFs.

Everywhere the electrical cable work is preferably underground because it is not easily damaged and also not affected by weather, therefore more reliable and has no risk of electrocution. Whenever a fault occurs within the underground cable, it is very difficult to find out the exact location of the fault for the exact cable. The main concept of this project is to find the distance of underground cable fault from the base station in kilometres. This project uses Ohms Law concept, when a low voltage DC is applied to the feeder end through a series resistor, then the current would differ based on the location of fault occurred in the cable. There are three types of cable fault like an open circuit fault, short circuit fault, ground fault or earth fault. All these types of faults are detected by the prototype of our project. The model uses Power supply , Arduino microcontroller , 16*2 liquid crystal display , GSM, Transformer, Rectifier, Voltage regulation, DC 0804,Relay, Relay driver, Fault Switches, Buzzer.

Since the volume level of the reservoir and impounding of the reservoir depend on the amount of sediment deposition, so the calculation of sediment has a great importance in the design of reservoirs and hydraulic structures. Soil erosion in the catchment and subsequently sedimentation in rivers, lakes and reservoirs is the main concern for two reasons; first, the basin surface soil loses its fertility, second, reservoir capacity is reduced and downstream water quality is reduced. Many studies have shown that the suspended sediments can be received, processed and estimated by remote sensing techniques and related software such as ENVI and GIS. Since applying the remote sensing technique has a greater speed and precision compared to traditional methods, it is used as an efficient technique in the modern.............

Controlling air quality is of the utmost importance within today's buildings. Vertical air curtains are often used to separate two different climatic zones in order to reduce heat transfer. This research work proposes an air curtain aimed to ensure a proper separation between two zones, a clean one and a contaminated one, which is to be used together with an air extraction from the ―contaminated‖ compartment. A CFD parametric study was carried out in order to assess the optimal parameters for achieving the aerodynamic sealing of the air curtain. The software OpenFOAM was used to carry out the simulations. This paper presents the numerical validation of the computational fluid dynamics model for contaminant control applications and the final simulation results...............

Due to the growth of web and internet technologies in last few decades rapid changed has been seen in most of the Manufacturing industry which revolutionized the manufacturing industry from local to global competitive industry. There are increased in customer demand for customized and high quality product with lower cost and shorter life cycle. In this agile environment, manufacturing industry need to be competitive, innovative, inter operative and collaborative to meet the changing demands of customer while maintaining productivity. Traditional manufacturing execution systems, supply chain management (SCM) and enterprise resource planning (ERP) are built upon rigid architecture that can't respond fully in dynamic environment. In these circumstances, the challenge is to develop an integrated solution that is intelligent, agile and robust and have the potential to meet environmental and customer demands................
