CAST: Tiering Storage for Data Analytics in the
"... Enterprises are increasingly moving their big data analytics to the cloud with the goal of reducing costs without sacrific-ing application performance. Cloud service providers offer their tenants a myriad of storage options, which while flex-ible, makes the choice of storage deployment non trivial. ..."

patterns and across-jobs interdependencies common in realistic analytics workloads. Tests with produc-tion workload traces from Facebook and a 400-core Google Cloud based Hadoop cluster demonstrate thatCast++ achieves 1.21 × performance and reduces deployment costs by 51.4% compared to local storage
1.l The Case for the Analytical Cache Model
"... Trace-driven simulation and hardware measurement are the techniques most often used to obtain accurate performance figures for caches. The former requires a large amount of simulation time to evaluate each cache configuration while the latter is restricted to measurements of existing caches. An anal ..."

. An analytical cache model that uses parameters extracted from address traces of programs can efficiently provide estimates of cache performance and show the effects of varying cache parameters. By representing the factors that affect cache performance, we develop an analytical model that gives miss rates for a
Performance-aware Energy Optimization on Mobile Devices in Cellular Network
"... Abstract—In cellular networks, it is important to conserve ener-gy while at the same time ensuring users to have good transmission experiences. The energy cost can result from tail energy due to the radio resource control strategies designed in cellular networks and data transmission. Existing effor ..."

Integral projection models for species with complex demography.
- American Naturalist
, 2006
"... abstract: Matrix projection models occupy a central role in population and conservation biology. Matrix models divide a population into discrete classes, even if the structuring trait exhibits continuous variation (e.g., body size). The integral projection model (IPM) avoids discrete classes and po ..."

and potential artifacts from arbitrary class divisions, facilitates parsimonious modeling based on smooth relationships between individual state and demographic performance, and can be implemented with standard matrix software. Here, we extend the IPM to species with complex demographic attributes, including
QOS WITH RELIABILITY AND SCALABILITY IN ADAPTIVE SERVICE-BASED SYSTEMS
"... Service-based systems that are dynamically composed at runtime to provide complex, adaptive functionality are currently one of the main development paradigms in software engineering. However, the Quality of Service (QoS) delivered by these systems remains an important concern, and needs to be manage ..."

to be managed in an equally adaptive and predictable way. To address this need, we introduce a novel, tool-supported framework for the development of adaptive servicebased systems called QoSMOS (QoS Management and Optimization of Service-based systems). QoSMOS can be used to develop service-based systems
Sustainability Policy Analysis: What Is It? What Can It Do for Us? Part One: Sustainability as an Analytical Framework
"... Few concepts are as influential or pervasive in contemporary political discourse as that of sustainability. The concept gained currency with the report of the World Commission on Environment and Development in 1987, Our Common Future. Its political relevance was established at the Rio Earth Summit ..."
Abstract

in Managing without Growth, the economic system is dynamic and may expand indefinitely while the ecological system is more static and subject to fixed limits (its carrying capacity). The choice thus turns from one of competing values to one of collective survival. Whatever one's views on the inherent
