Adaptive Preference Tradeoffs
… oppression. Prevailing opinion is that forced tradeoffs—especially following Serene Khader’s taxonomy—, like the case presented above, are a type of AP: one in which a person makes a decision because of a limited option set. In this paper I argue that no paradigm cases of forced tradeoffs …

Representation: preferences, priorities, and tradeoffs
… whether citizens are willing to make tradeoffs between descriptive and substantive representation. Answering this question is critical to efforts to maximize satisfaction with government for both minorities and members of the majority. This study makes four main contributions. First, …

Latency Tradeoffs in Distributed Storage Access
The performance of storage systems is central to handling the huge amount of data being generated from a variety of sources including scientific experiments, social media, crowdsourcing, and from an increasing variety of cyber-physical systems. The emerging high-speed storage technologies enable …

Power-Performance Tradeoffs in Database Systems
… energy usage of database servers and control the tradeoffs between energy consumption and system performance. In this thesis, we provide an in-depth anatomy of typical queries in various benchmarks and qualitatively analyze the energy profile of such queries. The results of extensive experiments …

Risk-Return Tradeoffs and Managerial incentives
… this assumption or the role of such risk-return tradeoffs in incentive compensation design. Using measures based on the firm’s stock price, I find that shareholder value increases with risk, consistent with managerial risk aversion imposing agency costs on shareholders. I also find that firms …

Tradeoffs and Limits in Computational Imaging
For centuries, cameras were designed to closely mimic the human visual system. With the rapid increase in computer processing power over the last few decades, researchers in the vision, graphics and optics community have begun to focus their attention on new types of imaging systems that utilize …

Latency-bandwidth tradeoffs in Internet applications
Wide-area Internet links are slow, expensive, and unreliable. This affects applications in two distinct ways. Back-end data processing applications, which need to transfer large amounts of data between data centers across the world, are primarily constrained by the limited capacity of Internet …

Environmental tradeoffs of denitrifying woodchip bioreactors
The development of row cropped agriculture on hydrologically altered landscapes in the Midwestern United States has led to environmental concerns. Tile drainage in this region acts as a conduit carrying sediment, nutrients, and other environmental pollutants to surface waters. Propelled by these …

Time and space tradeoffs in point location
We preprocess the input subdivision with n points on the plane in O(n√log n) time and store them in O(n/t) space to facilitate point location in O(log t) time, where t is an adjustable parameter. When t is a constant we get O(n) space and constant time. When t = O(n) we get constant space and O(log …

Tradeoffs in Designing Massively Parallel Accelerator Architectures
… of the performance-area and performance-power tradeoffs for the low level micro-architecture. We use this methodology to find the optimal design points for an accelerator architecture under area constraints and power constraints. Our results indicate that more complex architectures scale well …

Tradeoffs among ecosystem services in restored wetlands
… frequently involve choices that reflect tradeoffs among ecosystem services. Tradeoffs occur when one service changes at the expense of another. These tradeoffs are not always explicit, and can exist without our knowledge. As a consequence, land managers may make decisions that diminish …

Evaluating Fuel-Climate Tradeoffs in Contrail Avoidance
… work has estimated the fuel burn and climate tradeoffs associated with contrail avoidance by focusing on a small set of routes or weather conditions, targeting only specific regions of the world, focusing on minimizing contrail length without quantifying the contrail impact, limiting …

A programming language for precision--cost tradeoffs
… for many applications, trying to make these tradeoffs severely complicates the program, because there does not yet exist a programming model that gives the programmer the ability to easily describe the relevant tradeoffs between precision and cost of operations or to express in an algorithm …

Computational Tradeoffs and Symmetry in Polynomial Nonnegativity
Understanding when a polynomial is nonnegative on a region is a fundamental problem in applied mathematics. Although exact conditions for nonnegativity are computationally intractable, there has been a surge of recent work giving sufficient conditions for nonnegativity to address its many practical …

Integrated Framework for Aircraft Design and Assembly Tradeoffs
… higher production rates, lower costs, and better tradeoffs by leveraging the additional feedback loops produced via consideration of variables common to both disciplines. Finally, this framework is tested and compared with a state-of-the-art framework on a representative aircraft's wingbox and its …

Three essays evaluating tradeoffs in agricultural decision making
… act of decision making involves a choice amongst tradeoffs. In agriculture this is no different. This dissertation is composed of four papers that examine the tradeoffs being made across different agricultural decision making processes. The first two papers examine the tradeoffs made at the …

Improving capacity-performance tradeoffs in the storage tier
… and bandwidth aggregation. Typically these tradeoffs do not allow much choice with regard to capacity use. This work will leverage replication as the enabling mechanism to improve the capacity-performance tradeoff in the storage tier, while still providing for availability. ^ This …

Environmental Tradeoffs in Bioenergy Production and Agricultural Practices
… focus of this dissertation is the environmental tradeoffs of stover removal within the Corn Belt. The environmental tradeoffs considered are mainly concerned with managing soil erosion and soil quality. The analysis layers soil characteristics, management strategies and per acre costs using an …

Exploiting cost-performance tradeoffs for modern cloud systems
… systems. This thesis explores cost-performance tradeoffs for three types of systems that permeate today's clouds, namely (1) storage, (2) virtualization, and (3) computation. A distributed key-value storage system must choose between the cost of keeping replicas synchronized (consistency) and …
