An instance-based learning approach for evaluating the perception of ride-hailing waiting time variability

Michel Bierlaire, Nejc Gerzinic

Understanding user’s perception of service variability is essential to discern their overall perception of any type of (transport) service. We study the perception of waiting time variability for ride-hailing services. We carried out a stated preference su ...

Combining hypothesis- and data-driven neuroscience modeling in FAIR workflows

Daniel Keller

Modeling in neuroscience occurs at the intersection of different points of view and approaches. Typically, hypothesis-driven modeling brings a question into focus so that a model is constructed to investigate a specific hypothesis about how the system work ...

A Novel Approach to Modeling Enterprise Services Leveraging Object Cloning and Multilevel Classification

Alain Wegmann, Lam Son Lê

Object-oriented modeling is concerned with capturing common properties of objects. The dominant thinking in this realm is to classify objects that share certain properties into what is called a class, which in turn enables us to instantiate additional obje ...

A Design-oriented Charge-based Simplified Model for FDSOI MOSFETs

Christian Enz, Farzan Jazaeri, Alessandro Pezzotta, Louis Hutin

In this paper a design-oriented model for asymmetrical double-gate (ADG) MOSFETs is proposed. Including the back-gate effect into the original simplified EKV bulk model requires only one additional parameter to the existing four, and extends the simplified ...

Designing, Aligning, and Visualizing Service Systems

Gorica Tapandjieva Sekulovska

Service is a concept that separates the concerns of an organization into (1) the value created for users and (2) the way the organization manages its resources to provide this value. The discipline of management of information technology (IT) uses services ...

Setting contextual life-cycle objectives in urban design: requirements for a decision-support method

Marilyne Andersen, Thomas Bernard Paul Jusselme, Émilie Nault

A variety of building labels and norms exist that set evermore-ambitious environmental and energy performance targets. In parallel, a growing number of building performance evaluation tools are adopting the life-cycle assessment (LCA) methodology to allow ...
