Abstract: This study presents the thermodynamic performance characteristics; fuel power (FP), brake thermal efficiency (BTE), brake power (BP) and Specific fuel consumption (SFC) of petrol and diesel fuel. The experiments were conducted in two stages: constant load and constant speed.In constant load,the load is held constant and the speed is varied, and readings were taken, while in constant speed,the speed is held constant and the load is varied, and readings were taken. These tests were performed on cortina petrol engine testbed and diesel engine testbed for the petrol and diesel fuel respectively.Both engines are four stroke,four cylinder engines. The result showed that petrol engine requires more brake power than the diesel engine,however,the petrol engine has a lower fuel economy than the diesel engine.Thus, petrol engines are generally employed in light duty vehicles such as motorcycles, carsetc while the diesel engines are generally employed in heavy duty vehicles like trucks and earth moving equipment.

Abstract: Increasing in the industrial construction activities depending on conventional materials of concrete can lead to increased construction cost as well as scarcity of construction materials. This research was conducted aiming investigation of the changes in the mechanical properties of concrete following incorporation of different percentages of ceramic powder as partial replacement of ordinary Portland cement for compressive, split tensile strength and water absorption in comparison with conventional concrete. Experimental Results gained revealed that the concrete incorporated with low percent of ceramic powder exhibited significant elevation in compressive strength, splitting tensile strength, moreover lower water absorption at various ages compared to those of conventional concrete.

Abstract: With rapid improvement in life style of society, waste generation like municipal solid waste(MSW) is increasing which needs constructive utilization. In this paper gas turbine system is operated by burning municipal solid waste (MSW) as fuel in combustion chamber. The power output of gas turbine system is 1 MW operated throughout the year in Kolkata city, West Bengal, India. The excess power generated by gas turbine is used for operating the compressor. The air flow rate and fuel (municipal solid waste) flow rate are maintained in such a way that 1 MW power is obtained throughout the day. The temperature of air entering the compressor is ambient temperature of Kolkata city and gas coming out from combustion chamber is considered at a temperature of 1000 K. In Kolkata city the study..........

Abstract: One drawback of the Line of Balance (LOB) method is the unavailability of commercial software featuring its fundamentals. Studies pointed out this drawback as a factor that prevents a more frequent use. Recognizing the potential of the LOB method for managing construction projects, the objective of this paper is to propose a methodology for modeling Line of Balance schedules using CPM software like MS Project®. Previous researches developed an integrated Critical Path Method (CPM) and LOB model in an analytical nongraphical manner. This paper advances LOB modeling one step further to deal with other possible logical dependencies between activities. The presented framework can be used to develop a scheduling model that can link input and output data to commercial scheduling software; MS project®. The results of model application on a case study show the model ability in dealing with all possible relations with lags between activities and data transfer to MS project®.

Abstract: Knowing all characteristics of rotational system vibrations is most significant for a maintenance technician or engineer. Vibrations are carriers of a machine condition and by analysis of the vibration characteristics, it is possible to find what is the real cause of the vibrations. As a part of the research of rotational machinery vibrations, mathematical modeling of a rotational system is common tool before research is transferred to a real physical model. As an excellent method for this purpose, the best candidate could be a Finite Element Method. In this paper, an analysis of a Finite element model of rotational system motor – flexible coupling – rotor is presented. As a fault analyzed in this paper, misalignment and rotating looseness are modeled as external loads. For this FEM model of a rotational system is shown that it is suitable for the analysis of rotational machinery vibrations

Abstract: Liquid air energy storage is a new generation of air energy storage system that uses a liquefied air stored in a cryogenic liquid storage tank to form a potential energy reserve. Using Aspen HYSYS software to realize the simulation analysis of the combined process and independent process of liquid air energy storage system, based on the simulation results, it can be seen that the power consumption for liquefied air is much greater than the output work of liquefied air expansion, and its optimization direction is to combine the liquefied process with the Rankine cycle process to increase the overall efficiency of the system

Abstract: This paper presentsthe experimental results of the rheological behavior of cement stabilized dredged materials (DM) at high water contents. Slurries used for experiments were dredged from Baima Lake of Huai'an city and Tianjin Port of Tianjin city in China to prepare DM samples with various initial water contents (1.5~3.5 times of liquid limit). Various amounts of Portlandcement in different proportions (50~200 kg/m3) were added to stabilize the specimens. A series of laboratory tests were conducted on the treated specimens includingflow tests and viscosity tests. Test results have indicated that the flow value of the cement-stabilized DM increases with increasing initial............

Abstract: A time-dependent model designed for estimating the response of a horizontally loaded pile in a layered saturated soil is presented in the present paper. The results of the present model are compared with the results of existing solution; a better agreement is seen thereof, thus verifying this model. The present results show that the shear force of the pile decreases with increasing depth. The results also indicate that the displacement of the pile decreases as the depth increases. In addition, the pore pressure along the pile-length vanishes to zero as the time increases. This model shows the influence of the soil on a single horizontally loaded pile. When the depth of the soil increases, the shear force and displacement of the pile all decrease significantly.

Abstract: In this Study, we must stabilize the soil mass by using micropile. The micropile which is provided for soil stabilization is not greater than 300 mm in diameter. This type of study is taken because there are some limitations for execution of Soil Stabilization by a different technique like by providing pile having diameter is greater than 300 mm. If we provide pile then the heavy machinery is not easily going to site & create more vibration which affects the old building is existing nearby but in case of micropile the headroom required is less, the machine is lighter than pile M/c and creates very less vibration as compared to a pile. Also, the axial and lateral force a consideration during the design of micropile but in case of pile designing only axial force get into consideration. Micropile...........

Abstract: Rehabilitation programs of irrigation structures are essential in maintaining their functionality and increasing their life time. In irrigation systems involving large number of structures, prioritizing these structures in the rehabilitation program is essential in decision making process and budget allocation. In this study, a decision support system (DSS) was developed to prioritize and rank irrigation structures in the rehabilitation program. The developed DSS adopted the technique of Analytic Network Process (ANP) performed through the Super Decision (SD) V2.6.0 software. The developed DSS was applied to prioritize 140 Egyptian irrigation structures located in the River Nile irrigation system based on eight criteria. Results were checked using the well-known technique of Classic Multi Criteria Decision Making (CMCDM). The developed DSS proved high ability to deal with the huge amount of data collected with high accuracy for structures' prioritization.
