In this paper we investigate the use of a smartphone database to explore influences on travel behavior. Our aim is to exploit the rich individual-level data available from the smartphone to study the influence of communication and social contacts (collecte ...
In this paper, we identify transaction-local memory as a major source of overhead from compiler instrumentation in software transactional memory (STM). Transaction-local memory is memory allocated inside a transaction, which cannot escape (i.e., is capture ...
We introduce a generalization of the atomic snapshot object, which we call the partial snapshot object. This object stores a vector of values. Processes may write components of the vector individually or atomically scan any subset of the components. We inv ...
Worldwide globalization increases the complexity of problem solving and decision-making, whatever the endeavor is. This calls for a more accurate and complete understanding of underlying data, processes and events. Data representations have to be as accura ...
The interdisciplinary character of urban morphology using the fundamental trio - form, scale and history - tries to characterize what we call the primitive morphological ontology. However, this ontology is less useful in other domains unless a formal langu ...
To simulate realistic crowds of virtual humans in real time, three main requirements need satisfaction. First of all, quantity, i.e., the ability to simulate thousands of characters. Secondly, quality, because each virtual human composing a crowd needs to ...
The purpose of this paper is to present a novel approach to study sliding friction by the use of 3D multiscale coupling techniques. We highlight the difficulties of using multiscale schemes that couple molecular dynamics (MD) with finite elements to perfor ...
This paper asks how much liveness a transactional memory (TM) implementation can guarantee. We first devise a formal framework for reasoning about liveness properties of TMs. Then, we prove that the strongest liveness property that a TM can ensure in an as ...
The last decade has experienced a vivid enthusiasm to unravel the mystery of consciousness believed to be one of the major puzzles of humankind. We share this enthusiasm. Still,we feel that current models are incomplete suffering from a problem that we cal ...
complexity and computational social sciences. This paper draws from explicit (phone calls, SMS messaging) and implicit (proximity sensing based on Bluetooth radio signals) interaction patterns collected via smartphones and reality mining techniques to expl ...
