31st IARCS Annual International Conference on Foundations of Software Technology and Theoretical Computer Science (FSTTCS)
作者: Madry, Aleksander Panigrahi, Debmalya Microsoft Res New England Cambridge MA 02142 USA MIT Comp Sci & Artificial Intelligence Lab Cambridge MA 02139 USA
In this paper, we introduce the semi-stochastic model for dealing with input uncertainty in optimization problems. This model is a hybrid between the overly pessimistic online model and the highly optimistic stochasti... 详细信息

学位级别:硕士
Modern congestion and routing management algorithms work well for networks with static topologies and moderate QoS requirements. However, these algorithms may not be suitable for modern military networks with fluid dy... 详细信息

Increasing the efficiency of existing complex downstream processes by plant-wide retrofit
收藏 引用
CHEMICAL ENGINEERING RESEARCH & DESIGN 2015年 99卷 199-207页
作者: Lorenz, Hilke-Marie Otte, Daniel Staak, Daniel Repke, Jens-Uwe TU Bergahademie Freiberg Inst Thermal Environm & Nat Prod Proc Engn D-09596 Freiberg Germany Lonza Ltd CH-3930 Visp Switzerland
The economic feasibility of processes in the chemical industry is often determined by the energy and raw material demand, hence process efficiency is crucial. Most published methods to increase the efficiency of indus... 详细信息

A sum-over-paths algorithm for third-order impulse-response moment extraction within RC IC-interconnect networks
收藏 引用
SOLID-STATE ELECTRONICS 2015年 第Jul.期109卷 63-71页
作者: Wojcik, E. A. Ni, D. Lam, T. M. Le Coz, Y. L. Rensselaer Polytech Inst ECSE Dept Troy NY 12180 USA
We have created the first stochastic SoP (Sum-over-Paths) algorithm to extract third-order impulse-response (IR) moment within RC IC interconnects. It employs a newly discovered Feynman SoP Postulate. Importantly, our... 详细信息

COMPUTATIONAL STATISTICS & DATA ANALYSIS 2011年 第1期55卷 132-142页
作者: Barbillon, Pierre Celeux, Gilles Grimaud, Agnes Lefebvre, Yannick De Rocquigny, Etienne Univ Paris 11 INRIA Saclay Orsay France Ecole Cent Paris Paris France
In the uncertainty treatment framework considered, the intrinsic variability of the inputs of a physical simulation model is modelled by a multivariate probability distribution. The objective is to identify this proba... 详细信息

Prediction under uncertainty in reservoir modeling
收藏 引用
JOURNAL OF PETROLEUM SCIENCE AND ENGINEERING 2004年 第1-2期44卷 143-153页
作者: Subbey, S Christie, M Sambridge, M Heriot Watt Univ Inst Petr Engn Edinburgh EH14 4AS Midlothian Scotland Australian Natl Univ Inst Adv Studies Res Sch Earth Sci Canberra ACT 0200 Australia
Reservoir simulation is routinely employed in the prediction of reservoir performance under different depletion and operating scenarios. Usually, a single history-matched model, conditioned to production data, is obta... 详细信息

Unsupervised Nearest Neighbors Clustering With Application to Hyperspectral Images

IEEE JOURNAL OF SELECTED TOPICS IN SIGNAL PROCESSING 2015年 第6期9卷 1105-1116页
作者: Cariou, Claude Chehdi, Kacem Univ Rennes 1 IETR TSI2M Team CNRS UMR 6164 F-22300 Lannion France
We address the problem of unsupervised clustering of multidimensional data when the number of clusters is not known a priori. The proposed iterative approach is a stochastic extension of the kNN density-based clusteri... 详细信息

Approximation of exit times for one-dimensional linear diffusion processes

COMPUTERS & MATHEMATICS WITH APPLICATIONS 2020年 第6期80卷 1668-1682页
作者: Herrmann, Samuel Massin, Nicolas Univ Bourgogne Franche Comte CNRS UMR 5584 Inst Math Bourgogne IMB F-21000 Dijon France
In order to approximate the exit time of a one-dimensional diffusion process, we propose an algorithm based on a random walk. Such an algorithm was already introduced in both the Brownian context and the Ornstein-Uhle... 详细信息

Bayesian Mixed Effect Atlas Estimation with a Diffeomorphic Deformation Model

SIAM JOURNAL ON IMAGING SCIENCES 2015年 第3期8卷 1367-1395页
作者: Allassonniere, S. Durrleman, S. Kuhn, E. Ecole Polytech CMAP F-91128 Palaiseau France INRIA Paris Roquencourt Aramis Lab F-75013 Paris France Univ Paris 06 Sorbonne Univ UMR 1127 F-75013 Paris France CNRS UMR 7225 F-75013 Paris France ICM F-75013 Paris France INRA Unite MIA F-78352 Jouy En Josas France
In this paper we introduce a diffeomorphic constraint on the deformations considered in the deformable Bayesian mixed effect template model. Our approach is built on a generic group of diffeomorphisms, which is parame... 详细信息

A sum-over-paths impulse-response moment-extraction algorithm for RLCM IC-interconnect networks
收藏 引用
SOLID-STATE ELECTRONICS 2007年 第8期51卷 1109-1123页
作者: Le Coz, Y. L. Krishna, D. Petranovic, D. M. Rensselaer Polytech Inst ECSE Dept Troy NY 12180 USA Mentor Graph Corp Wilsonville OR 97070 USA
We have created a new impulse-response (IR) moment-extraction algorithm for RLCM circuit networks. It employs a Feynman sumover-paths postulate. Our approach begins with generation of s-domain nodal-voltage equations.... 详细信息
