Development of the Guide Tube for Magnetic High Field Side Pellet Injection
, 2001
"... For attaining a higher fueling efficiency in JT-60U centrifugal pellet injection experiments, guide tubes for a magnetic high-field side (HFS) injection were developed. The guide tube for HFS (top) injection is about l5 m in length, 5 mm in inner diameter and 600 mm in the smallest curvature radius, ..."

High Field Side Penetration Depth Scaling Studies at ASDEX Upgrade
"... In modern tokamak experiments refueling of plasmas by the injection of frozen hydrogen isotope pellets is a promising approach. By injecting the pellets from the magnetic high field side (HFS) a grad B induced drift [1] accelerates the deposited material toward the center of the plasma, hence achiev ..."

High field side measurements of non-thermal electron cyclotron emission on TCV plasmas with ECH and ECCD. Plasma Phys
- Control. Fusion
"... Abstract. Measurements of electron cyclotron emission from the high field side of the TCV tokamak have been made on plasmas heated by second and third harmonic X-mode Electron Cyclotron Heating (ECH) and Electron Cyclotron Current Drive (ECCD). Suprathermal Electron Cyclotron Emission (ECE), up to a ..."

Markov Random Field Models in Computer Vision
, 1994
"... . A variety of computer vision problems can be optimally posed as Bayesian labeling in which the solution of a problem is defined as the maximum a posteriori (MAP) probability estimate of the true labeling. The posterior probability is usually derived from a prior model and a likelihood model. The l ..."

. The latter relates to how data is observed and is problem domain dependent. The former depends on how various prior constraints are expressed. Markov Random Field Models (MRF) theory is a tool to encode contextual constraints into the prior probability. This paper presents a unified approach for MRF modeling
Formal Ontology and Information Systems
, 1998
"... Research on ontology is becoming increasingly widespread in the computer science community, and its importance is being recognized in a multiplicity of research fields and application areas, including knowledge engineering, database design and integration, information retrieval and extraction. We sh ..."

is the adoption of a highly interdisciplinary approach, while on the architectural side the most interesting aspect is the centrality of the role they can play in an information system, leading to the perspective of ontology-driven information systems.
New results in linear filtering and prediction theory
- TRANS. ASME, SER. D, J. BASIC ENG
, 1961
"... A nonlinear differential equation of the Riccati type is derived for the covariance matrix of the optimal filtering error. The solution of this "variance equation " completely specifies the optimal filter for either finite or infinite smoothing intervals and stationary or nonstationary sta ..."

in this field. The Duality Principle relating stochastic estimation and deterministic control problems plays an important role in the proof of theoretical results. In several examples, the estimation problem and its dual are discussed side-by-side. Properties of the variance equation are of great interest
MULTILISP: a language for concurrent symbolic computation
- ACM Transactions on Programming Languages and Systems
, 1985
"... Multilisp is a version of the Lisp dialect Scheme extended with constructs for parallel execution. Like Scheme, Multilisp is oriented toward symbolic computation. Unlike some parallel programming languages, Multilisp incorporates constructs for causing side effects and for explicitly introducing par ..."

parallelism. The potential complexity of dealing with side effects in a parallel context is mitigated by the nature of the parallelism constructs and by support for abstract data types: a recommended Multilisp programming style is presented which, if followed, should lead to highly parallel, easily
Design of capacity-approaching irregular low-density parity-check codes
- IEEE TRANS. INFORM. THEORY
, 2001
"... We design low-density parity-check (LDPC) codes that perform at rates extremely close to the Shannon capacity. The codes are built from highly irregular bipartite graphs with carefully chosen degree patterns on both sides. Our theoretical analysis of the codes is based on [1]. Assuming that the unde ..."
