Abstract: This paper focuses on the comparison of the behavior of a panel type MSE wall using the existing geosynthetic strip and steel strip reinforcement with the behavior of a suggested design of panel type MSE wall using wider geogrid reinforcement subjected to various compaction loadings and built above bedrock and stiff clay soil foundation. The behavior of the MSE wall is analyzed using finite element method in Plaxis 3D program. The numerical simulations showed that wider geogrid reinforcement exhibited similar lateral displacement with negligible difference compared to steel strip reinforcement having 26 times larger stiffness value. Also, wider geogrid reinforcement obtained higher stability level compared to strip reinforcements............

Keywords: MSE wall, compaction effect, geogrids, steel strips, geo-strips, lateral displacement

Abstract: In this paper input data has been collected from the real existing system and proposed AMS simulation models are developed using C programming. The flow of job through the system managed with multi-level scheduling rules related to launching of job in to a system. The proposed simulation models are modeled for the existing system and optimum part selection rule is determined for the performance parameters such as Make Span, mean flow time, average part waiting time.

Key Words: Part launching, Scheduling, and Simulation model.

Abstract: The Petroleum Industry is one of the largest and broadest entrepreneurs of the world, and it grows each year, with new technologies and new innovation perspectives. The hydrocarbon exploration is a risk-filled activity, requiring dangerous tasks involving very high pressures and the manipulation of gigantic amounts of gas. Therefore, all equipment need to meet security standards. This paper was based on improving a machine component to meet the requirements on the API 610/671 Standards. The coupling used in the past could cause sparking, creating dangerous explosions, and if there were severe vibrations, their blades could come loose, becoming a danger for operators In order to meet the API 610/671 Standards, a change was made to the coupling design, where a study was carried out to select a new material with more adequate mechanical characteristics for the work, phosphatizing thermal treatment and salt spray tests to analyze the material life time.

Key Words: Blade coupling, API 610/671 Standards, Petroleum, Security

Abstract: Elastoplastic dimensioning is an important step in the design of Tubesheets. Indeed, they must be as thin as possible in order to reduce the internal temperature gradients and the risks related to thermal fatigue, and at the same time, to reduce the industrialization costs related to the material and perforations. Several studies have been developed with the aim of finding an elastoplastic model of calculation which is the most appropriate in analytical theor1,2 or using finite element method. The aim of this work is, then to propose a 2D Typical model for the numerical simulation of the circular clamped perforated thin plates behavior in the elastic and elastoplastic domains. Unlike the majority of the literature calculations that are based on the equivalent solid plate model,this Model is based on the real geometry of plates and takes into account different perforation distribution patterns and ligament factors and it is then validated by experiments1

Abstract: The residential housing sector (G+3,G+6 etc.) use of steel has increased, but RCC construction still predominates the Indian construction business.In the present study an attempt has been made to analyze the seismic behavior of RCC and steelframes using Etabs2015.The high self-weight and brittleness of concrete is not favorable to seismic prone structures whereas steel structures are 60% lesser in weight through they can withstand earthquake more effectively than the concrete structures. Aim of the study to compare the seismic performance of G+6 and G+9 frames for both steel and RCC. For current study all frames are analyzed under equivalent static method. In this comparative study it is concluded that steel frames are most effective than the concrete as it has the highest strength to weight ratio.

Abstract: This paper summarizes the ongoing researches about the defects in Flexible and Rigid pavement and the maintenance in Flexible and Rigid pavements. In the past, lots of researchers have already studied the defects and problems of maintaining the Flexible and Rigid pavements all over the world. Efforts have been made to refer some of the publications related to this topic. Various defects in Flexible and Rigid pavements have been identified since the existence of Flexible and Rigid pavement. Pavement structure can be destroyed in a single season due to water penetration .Defects in Flexible and Rigid pavements is a problem of multiple dimensions, phenomenal growth of vehicular traffic (in terms of no. of axle loading of commercial vehicles), the rapid expansion in the road network, non-availability.............

Abstract: This paper gives a review of the vibration characteristics and its analysis associated with two stroke low speed marine diesel engines and its counteract measures.Marine diesel engines are variable speed engines and face resonance vibration in a narrow band speed within its speed range and this band is called as barred speed range. The historical strategy for vibration control has been sub-critical design criteria. This strategy adopts vibration analysis of local primary forces of machinery components and thereby neglects the impact of secondary forces. Recently, Global vibration analysis has been adopted to reduce the influence of barred speed rangeand secondary excitations. In this paper, we study the performance comparison of both sub-critical design criteria and global vibration analysis...

Abstract: Air pollution is the release of air pollutants into the atmosphere. Those pollutants may be gases or particulate matter and can come from a variety of sources. These are carbon monoxide, sulfur dioxide, nitrogen oxides, ozone, particulate matter and lead. Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. 𝑆𝑂2, 𝑁02 𝑎𝑛𝑑 SPM is the good indicators of automobile pollution. In this paper, air quality of many places of Chennai in India was calculated and impact of human health is presented..

Abstract: Engine is the most critical operating mechanism in industrial machines. Its function is to transmit power to the parts of the machine. Diesel power plants utilize two or four stroke engines in their operations and needs to be lubricated with the appropriate lubricant to maintain their performance and reliability. The lubricant creates a thin film between the sliding surfaces thus reducing friction in the machine. Base oil and additives are two ingredients of the lubricant. The base oil gives lubrication to the moving parts to protect them from wear caused by friction while additives prevents deterioration of oil under extreme temperature. Condition monitoring in power plants arises from the fact that in a power plant unexpected fault or shutdown may result to fatal accident or huge loss of output. The recent development in computer and transducer technologies, signal processing and artificial–intelligence (AI)............

Abstract: The general public of service users have not understood about the value of construction consultancy services. This hampers marketing opportunities in the private sector for construction consulting services particularly, in South Kalimantan. The objective of the research is to create an appropriate marketing strategy for corporation construction consultancy services in South Kalimantan. It can be identified by SWOT analysis, AHP analysis, and Importance Performance-Analysis. This research is done by giving the questionnaire to the service users and construction consulting firms in South Kalimantan. The result of its are, a model of the marketing strategy of the construction consulting service, Strength-Opportunity strategy, grow and build it, service pricing strategy, and basic strategy. This model is a collaboration between the marketing-mix and service quality.
