A virtual environment is a computer-generated world accessible to a (human) user through input/output devices. It is similar to a traditional simulation but with an emphasis on threedimensional graphics, immersion and real-time interaction. A distributed virtual environment has several participants interacting simultaneously with the virtual world. An example application would be a surgical tra...

Producer-initiated communication mechanisms have been proposed to reduce communication latency in distributed shared memory systems. These mechanisms aim to move data close to its consumers, as soon as it is produced. The data is then available locally when needed by the consumer, avoiding the latency of retrieving it from global memory or from the producer’s cache. Studies have shown that thes...

Determining injector-producer relationships, i.e., to quantify the inter-well connectivity between injectors and producers in a reservoir, is a complex and non-stationary problem. In this paper, we present a neural-network-based sensitivity analysis approach to address this problem. To the best of our knowledge, sensitivity analysis has never been applied for identification of the injector-prod...

We study the performance of a stylized supply chain where multiple retailers and a single producer compete in a Cournot-Stackelberg game. At time t = 0 the retailers order a single product from the producer and upon delivery at time T > 0, they sell it in the retail market at a stochastic clearance price. We assume the retailers’ profits depend in part on the realized path of some tradeable sto...
