Restoration of a polluted river front is as important as conservation of a polluted river itself because its shore line has the potential of making the conservation project self-sustainable. In the present study, an attempt has been made to study the polluted river front of a river in India. A self-sustainable restoration and development experimental plan has been prepared for the area considered in the study. This experimental plan aims at utilizing arable land strips on both sides of the river, currently deserted or encroached by rank vegetation, open wastewater drains, etc. The cost estimates have also been presented for various items and actions proposed under this study to prove its economical sustainability in the long run. The proposed plan and the existing conditions have been compared using CIPAR index to ensure increased public accessibility. It has been found that the present unsatisfactory conditions of the riverfront considered in this study can be raised to more than 90 % satisfaction by implementation of the proposed plan in a period of 3 to 4 years. HYDRO Nepal JournalJournal of Water Energy and EnvironmentIssue: 21, July, 2017Page: 25-33Upload Date: July 18, 2017

Variability and uncertainty in renewable energy generation has a direct impact on the cost of electricity prices because of the potential impacts on the operation of existing power generating units. The purpose of this paper is to present a case study detailing the variability added to the UC Merced campus load after including a 1-MW photovolataic (PV) plant to supply a significant amount (25–30% of maximum demand) of the energy load. Cost estimates of the required mechanisms to compensate for the variability are calculated based on utility prices and the PV power output fluctuations. The resulting cost estimates are then compared with solar power variability metrics in order to show the economic impacts of solar variability. Additionally, a simulation is performed for a integrated battery storage system to mitigate the PV fluctuations by solving a revenues optimization formulation. The simulated costs are also correlated with three variability metrics including the standard deviation of the fluctuations and the mean absolute values of the fluctuations. In order to extrapolate results from the case study to a more general scenario, we show that the obtained correlations of normalized variables can be useful for providing estimates on the financial impacts of variable generation resources based on more widely available solar irradiance data.

One of the most important challenges and obstacles faced by tomato farmers in the new lands is the scarcity of productive resources and their high cost, especially the suppliers of fresh water and arable land, which negatively affects the net yield. Therefore, this research paper aims to make a comparison between tomato production using traditional greenhouses (with soil) and using Hydroponics technology in the new lands with the research sample, aiming to measure the effect of using hydroponics in agricultural greenhouses on the most important indicators of economic returns, by studying and analyzing the cost components of the two production types and studying the most important productive, economic and financial indicators.

Shift to The Front II Komplek Sukamukti Banjaran Project is one of the projects implemented by one of the companies engaged in telecommunications. In its implementation, each project including Shift to The Front II Komplek Sukamukti Banjaran has a time limit specified in the contract. Project scheduling is an important role in predicting both the cost and time in a project. Every project should be able to complete the project before or just in the time specified in the contract. Delay in a project can be anticipated by accelerating the duration of completion by using the crashing method with the application of linear programming. Linear programming will help iteration in the calculation of crashing because if linear programming not used, iteration will be repeated. The objective function in this scheduling is to minimize the cost. This study aims to find a trade-off between the costs and the minimum time expected to complete this project. The acceleration of the duration of this study was carried out using the addition of 4 hours of overtime work, 3 hours of overtime work, 2 hours of overtime work, and 1 hour of overtime work. The normal time for this project is 35 days with a service fee of Rp. 52,335,690. From the results of the crashing analysis, the alternative chosen is to add 1 hour of overtime to 34 days with a total service cost of Rp. 52,375,492. This acceleration will affect the entire project because there are 33 different locations worked on Shift to The Front II and if all these locations can be accelerated then the duration of completion of the entire project will be effective

Abstract A component failure has the potential to significantly impact the cost, manufacturing schedule, and/or the perceived reliability of a system, especially if the root cause of the failure is not known. A failure analysis is often key to mitigating the effects of a componentlevel failure to a customer or a system; minimizing schedule slips, minimizing related accrued costs to the customer, and allowing for the completion of the system with confidence that the reliability of the product had not been compromised. This case study will show how a detailed and systemic failure analysis was able to determine the exact cause of failure of a multiplexer in a high-reliability system, which allowed the manufacturer to confidently proceed with production knowing that the failure was not a systemic issue, but rather that it was a random “one time” event.

Resultant Wave

As the wave forces are the function of the wave height, period and the angle between the incoming wave direction and the axis of the discharge pipeline, the resultant wave force is directly related to the alignment of the pipeline. In this paper, a method is explained to determine an optimum pipeline route for which the resultant wave force becomes minimum and hence, the cost of the constructive measures may decrease. Also, the application of this method is submitted through a case study.

Realistic Goal

Between 2007 and 2011, Wootton Bassett, a small Wiltshire town in the UK, became the focus of national attention as its residents responded to the regular repatriations of dead soldiers through its High Street. The town’s response came to symbolize the way that broader attitudes developed and changed over that period. As such, it is a fascinating case study in civil–military relations in the twenty-first century. Success may be the same as victory, but victory, at least as it has been traditionally understood, is not a realistic goal in many types of contemporary conflict. Discretionary wars—conflicts in which national survival is not an issue and even vital national interests may not be at stake—pose particular challenges for any government which does not explain why the cost being paid in blood and treasure is ‘worth it’.
