This paper illustrates and extends an efficient framework, called the square-root-elastic (SRE) framework, for studying shapes of closed curves, that was first introduced in [2]. This framework combines the strengths of two important ideas - elastic shape metric and path-straightening methods - for finding geodesics in shape spaces of curves. The elastic metric allows for optimal matching of fe...

The transition from initial education to work has received a great amount of attention, but hardly any research treats this process holistically. This paper focuses on the serial succession of statuses instead of on single events in the early years after leaving full-time education. As methodological tool Sequence Analysis will be applied. Optimal matching procedures allow for the direct compar...

The field of approximation algorithms for clustering is a very active one and a large number of algorithms have been developed for clustering objectives such as k-median, min-sum, and sparsest cut clustering. For most of these objectives, the approximation guarantees do not match the known hardness results, and much effort is spent on obtaining tighter approximation guarantees [1, 4, 5, 8, 6, 9...

Case-control studies for association are widely used for finding genetic variants causally associated with phenotypes. Unfortunately, population structure can induce false positives. For instance, if cases and controls have different genetic backgrounds, differences in frequencies of distinct forms of variants might be due to differences in ancestral population of origin. Traditional approaches...

There has been a significant volume of recent work on FPGA designs for pattern matching. Although various pattern-matching architectures have been presented, attempts to compare different designs have been inconclusive, or even misleading, due to the lack of a common evaluation framework. In this paper, we present an analytical model of FPGA pattern-matching architectures that quantitatively ex...

A robust ground penetrating radar (GPR) signal processing approach is developed and applied to the sensing of surface soil and ice/water layers as well as near-surface buried objects. The principal technique relies on a reference set of waveforms which are tested for optimal matching with measured radar reflections to be analyzed. In principle the reference set can be based on measurements as w...

A method is introduced for model order reduction of large circuits extracted from layout. The algorithm, which is based on balanced realization, can be used for reducing the order of circuits before circuit-level simulation. In contrast to Padebased algorithms which match the reduced order system with original system in some given frequencies, balanced realization based model algorithms provide...

Mass-scale red blood cell genotyping of donors and transfusion recipients increases the availability extended antigen matched units. Therefore, a new mathematical framework is developed that can be applied for general groups (i.e., beyond ABO, RhD groups). It determines which units should issued from inventory, such requests hospitals satisfied with compatible units, shortages future are avoide...
