Multi-Objective Management of Multiprocessor Systems: From Heuristics to Reinforcement Learning

Arman Iranfar

In my thesis, I reveal several already-existing and emerging challenges in multi-objective management of multiprocessor systems, and address them through novel solutions, from heuristics to RL, depending on the complexity of the problem. Conventional multi ...

Nutrients influence seasonal metabolic patterns and total productivity of Arctic streams

Luis Gómez Gener

The seasonality of gross primary production (GPP) in streams is driven by multiple physical and chemical factors, yet incident light is often thought to be most important. In Arctic tundra streams, however, light is available in saturating amounts througho ...

Imitation, Proximity, and Growth - A Collective Swarm Dynamics Approach

Max-Olivier Hongler, Olivier Gallay, Fariba Hashemi

This paper is based on the premise that economic growth is driven by an interplay between innovation and imitation in an economy composed of interacting ̄rms operating in a stochastic environment. A novel approach to modeling imitation is presented based o ...

An assessment of how well we account for intangibles

Gaétan Jean A de Rassenfosse

Estimates of intangible capital stock are of prime importance for accurate measurement of productivity growth. Aggregate intangible capital stock is usually estimated using the so-called Corrado-Hulten-Sichel (CHS) new growth accounting framework. Yet this ...

At the Origins of Learning: Absorbing Knowledge Flows from within the Team

Fabiana Visentin, Michele Pezzoni, Charles Chadi Ayoubi

Empirical studies document a positive effect of collaboration on team productivity. However, little has been done to assess how knowledge flows among team members. Our study addresses this issue by exploring unique rich data on a Swiss funding program prom ...

The productivity of science & engineering PhD students hired from supervisors’ networks

Fabiana Visentin, Annamaria Conti, Stefano Horst Baruffaldi

We compare the scientific productivity of PhD students who are hired from a fine-grained set of mutually exclusive affiliation types: a PhD supervisor's affiliation, an external affiliation from which the supervisor derives her coauthors, and an external a ...
