for the parameters of a linear cross-sectional spatial-auto...
Eye movements and an object-based model of heading perception
Eye movements object-based model heading perception
2015/8/13
The movement of an observer through an environment of stationary objects creates a complex set of motions called optical flow. Accurately registering these motions with our mobile eyes and acting upon...

Mathematical Model Interpretable Clinical Decision Support Applications Gynecology
2015/7/9
Over time, methods for the development of clinical decision support (CDS) systems have evolved from interpretable and easy-to-use scoring systems to very complex and non-interpretable mathematical mod...
Nonconvex Model Predictive Control for Commercial Refrigeration
Energy management Optimization methods Predictive Control Nonlinear control systems
2015/7/9
We consider the control of a commercial multi-zone refrigeration system, consisting of several cooling units that share a common compressor, and is used to cool multiple areas or rooms. In each time p...

We consider the operation of a wind turbine and a connected local battery or other electrical storage device, taking into account varying wind speed, with the goal of maximizing the total energy gener...
Business Model Innovation and Competitive Imitation: The Case of Sponsor-Based Business Models
Business Model Innovation and Invention Market Entry and Exit Competitive Strategy Competitive Advantage Value
2015/4/23
We study sponsor-based business model innovations where a firm monetizes its product through sponsors rather than setting prices to its customer base. We analyze strategic interactions between an inno...
