Contextual Factors in the Adoption of Social Software: a Case Study

Denis Gillet, Maryam Najafian-Razavi

Over the past decade, social computing has emerged immensely as a phenomenon among distributed communities. The benefits of social systems depend on a large part on the existence of an active user community who use it continuously to deploy and share infor ...

Cerebrospinal fluid hydrodynamics in type I Chiari malformation

Bryn Andrew Martin

Purpose: The objective of this study was to review past studies that have used engineering analysis to examine cerebrospinal fluid hydrodynamics in cranial and spinal subarachnoid spaces in both healthy humans and those affected by type I Chiari malformati ...

The origin of early age expansions induced in cementitious materials containing shrinkage reducing admixtures

Karen Scrivener, Barbara Lothenbach, Patrick Juilland

Studies on the early-age shrinkage behavior of cement pastes, mortars, and concretes containing shrinkage reducing admixtures (SRAs) have indicated these mixtures frequently exhibit an expansion shortly after setting. While the magnitude of the expansion h ...

Betatron squeeze optimisation at the Large Hadron Collider based on first year of operation data

Xavier Buffat

In order to achieve the high luminosity expected from the Large Hadron Collider, the beta function at the interaction points must be minimised. As the aperture in the surroundings of the interaction points become smaller and smaller with decreasing beta fu ...

Dynamic response of a rock block in a plunge pool due to asymmetrical impact of a high-velocity jet

Anton Schleiss, Erik Bollaert, Matteo Paolo Elia Antonio Federspiel

Flood release structures of high-head dams generate high-velocity plunging jets. These may scour the downstream rocky riverbed and even damage the dam foundation. Assessment of the scour evolution is essential to ensure the safety of the dam and appurtenan ...

Enhancing Pilot Performance with a SymBodic System

Daniel Thalmann, Dario Floreano, Walter Karlen, Sylvain Cardin

Increased fatigue of pilots during long flights can place both humans and machine at high risk. In this paper, we describe our research on a SymBodic (SYMbiotic BODies) system designed to minimize pilot fatigue in a simulated 48 hour mission. The system de ...

Robust Dynamically Deployed Static Analysis for Java

Sebastian Gfeller

Guaranteeing the absence of errors in a program is a great challenge and many static analysis techniques have been developed to see whether a program is correct before we run it. There is, however, a whole class of programs that are especially difficult to ...

Scalable Delivery of Stream Query Result

Karl Aberer, Ali Salehi

Continuous queries over data streams typically produce large volumes of result streams. To scale up the system, one should carefully study the problem of delivering the result streams to the end users, which, unfortunately, is often over-looked in existing ...

Reference-based vs. task-based evaluation of human language technology

Andrei Popescu-Belis

This paper starts from the ISO distinction of three types of evaluation procedures – internal, external and in use – and proposes to match these types to the three types of human language technology (HLT) systems: analysis, generation, and interactive. The ...
