We explore time-varying networks for high-dimensional locally stationary time series, using the large VAR model framework with both the transition and (error) precision matrices evolving smoothly over...
New findings on the diet of Arctic foxes, determined by the condition of their teeth, show how varying climate conditions in the Arctic affect the animals that live there.In a U.S. National Scien...
Document classification is an area of great importance for which many clas-sification methods have been well developed. However, most of these methods cannot generate time-dependent classification rul...
We present results from direct N-body simulations of collisions between gravitational aggregates of varying size as part of a study to parameterize planetesimal growth in the Solar System. We find tha...
Bifurcation theory is often used to investigate the inception of a shear band in a homogeneously deforming body. The theory predicts conjugate shear bands that have the same likelihood of triggering. ...
A two-factorial experiment was carried out on 6 groups (10 animals each) of Polish Black and White Holstein-Friesian cows in the transition period to determine the effect of glucogenic additive (G...
In this paper we give a direct derivation of the solution to the continuous time finite horizon H-infinity synthesis problem. An explicit separation of the time domain cost function into past and futu...
In this paper we construct suboptimal H-infinity controllers which satisfy a new robust performance condition, using the receding horizon technique. A method is described for the synthesis of H-infini...
In this paper new techniques are developed for the analysis of linear time varying (LTV) systems. These lead to a formally simple treatment of problems for LTV systems, allowing methods more usually r...
This paper considers control design for distributed systems, where the controller is to adopt and preserve the spatial structure of the system. Specifically systems that vary spatially are considered;...
New techniques are presented for the model reduction of linear time-varying and linear periodically-varying systems, including the formulation and proof of guaranteed upper bounds for the error. The c...
Error-bounds are developed for balanced truncation of linear time-varying systems, leading to an extension of the `twice the sum of the tail' formulae, well-known in the time-invariant case. The appro...
In this paper new techniques are developed for the analysis of linear time varying (LTV) systems. These lead to a formally simple treatment of robust control problems for LTV systems, allowing methods...
In the Erdalen and Bødalen drainage basins located in the inner Nordfjord in western Norway the soils were formed after deglaciation. The climate in the uppermost valley areas is sub-arctic ocean...
