Motion Classification and Step Length Estimation for GPS/INS Pedestrian Navigation
"... Abstract The primary source for pedestrian navigation is the well known Global Positioning System. However, for applications including pedestrians walking in urban or indoor environments the GPS is not always reliable since the signal often is corrupted or completely blocked. A solution to this pro ..."

An Improved Algorithm for the Evaluation of Fixpoint Expressions
, 1996
"... Many automated finitestate verification procedures can be viewed as fixpoint computations over a finite lattice (typically the powerset of the set of system states). For this reason, fixpoint calculi such as those proposed by Kozen and Park have proven useful, both as ways to describe verification ..."

algorithms and as specification formalisms in their own right. We consider the problem of evaluating expressions in these calculi over a given model. A naive algorithm for this task may require time n q , where n is the maximum length of a chain in the lattice and q is the depth of fixpoint nesting
XTRACT: A System for Extracting Document Type Descriptors from XML Documents
 MOD
, 20001999
"... XML is rapidly emerging as the new standard for data representation and exchange on the Web. An XML document can be accompanied by a Document Type Descriptor (DTD) which plays the role of a schema for an XML data collection. DTDs contain valuable information on the structure of documents and thus ha ..."

of regular expressions, naive approaches typically fail to produce concise and intuitive DTDs. Instead, the XTRACT inference algorithms employ a sequence of sophisticated steps that involve: (1) finding patterns in the input sequences and replacing them with regular expressions to generate “general
Fast algorithms for finding O(congestion + dilation) packet routing schedules
 Combinatorica
, 1999
"... In 1988, Leighton, Maggs, and Rao showed that for any network and any set of packets whose paths through the network are fixed and edgesimple, there exists a schedule for routing the packets to their destinations in O(c+d) steps using constantsize queues, where c is the congestion of the paths in ..."

Feasibility Study of a Gradient Redirecting Algorithm Combined with Step Length Estimation for Including A Priori Data in the Image Reconstruction in Microwave Tomography
"... An iterative electromagnetic timedomain inversion algorithm for microwave tomography exploiting a priori data of the dielectric properties of the object being imaged is described. The algorithm is based on solving the regular and the adjoint Maxwell’s equations in order to compute gradients, which ..."

 Journal of Visual Communication and Image Representation
, 2000
"... this paper, we propose an active contour algorithm for object detection in vectorvalued images (such as RGB or multispectral). The model is an extension of the scalar ChanVese algorithm to the vectorvalued case [1]. The model minimizes a MumfordShah functional over the length of the contour, ..."
