This paper focuses on the trade-off between the deduplication rate and the processing penalty in backup system which uses a conventional variable chunking method. The trade-off is a nonlinear negative correlation if the chunk size is fixed. In order to analyze quantitatively the trade-off all over the factors, a simulation approach is taken and clarifies the several correlations among chunk siz...

wind erosion is a major environmental issue affecting land resources and socio-economic settings in iran. this paper outlines a study undertaken to provide a new tool to manage wind erosion from physical and economic perspectives. the southern part of the varamin plain in south of tehran is used as a case study. the focus of this study is on exploring the economic and physical impacts of 16 veg...

this paper explores the leverage determinants across firms’ sizesbased on the two main theories behind the capital structure, the trade-offand the pecking order theories. a panel data is sued to find therelationship between capital structure and the variables that proxy forbenefits and costs of debt during 1990 to 2006. our findings show thatboth principles help to explain the capital structure...

Trade-off is one of the main design parameters in the field of electronic circuit design. Whereas smaller electronics devices which use less hardware due to techniques like hardware multiplexing or due to smaller devices created due to techniques developed by nanotechnology and MEMS, are more appealing, a trade-off between area, power and speed is inevitable. This paper analyses the trade-off i...

Large-scale simulations play a central role in science and the industry. Several challenges occur when building simulation software, because simulations require complex software developed in a dynamical construction process. That is why simulation software engineering (SSE) is emerging lately as a research focus. The dichotomous trade-off between efficiency and scalability (SE) on one hand and ...

Two different types of trade-offs have been discussed with regard to memory for emotional information: A trade-off in the ability to remember the gist versus the visual detail of emotional information, and a trade-off in the ability to remember the central emotional elements of an event versus the nonemotional (peripheral) elements of that same event. The present study examined whether these tw...

In common models of project time-cost trade-off, time value of money is not considered and often time-cost trade-off is performed without considering time value of money. In real world, pass of time causes decrease in money value. Therefore, taking into account the time value of money in time-cost trade-off problem makes this problem is becoming more and more realistic. In this paper, we study ...

A trade-off between immune system and moulting is predicted in birds, given that both functions compete for resources. However, it is unclear whether such a trade-off exists during post-breeding moult. This study tests such a trade-off in the house sparrow (Passer domesticus). Males injected with an antigen (lipopolysaccharide) significantly moulted slower than sham-injected males. Moreover, ma...

This article analyses the conflict between trade values and other values ('trade and ... problems'), such as environmental protection, labour rights or free competition, as It Is addressed by the principal legal devices available to address such conflicts ('trade-off devices') In the dispute resolution context In the European Union, the GATT/World Trade Organization system and In the United Sta...

Immune defense and reproduction are physiologically and energetically demanding processes and have been observed to trade off in a diversity of female insects. Increased reproductive effort results in reduced immunity, and reciprocally, infection and activation of the immune system reduce reproductive output. This trade-off can manifest at the physiological level (within an individual) and at t...
