On a New Method for Derivative Free Optimization
A new derivative-free optimization method for unconstrained optimization of partially separable functions is presented. Using average curvature information computed from sampled function values the method generates an ...
Regular Expressions with Numerical Constraints and Automata with Counters
Regular expressions with numerical constraints are an extension of regular expressions, allowing to bound numerically the number of times that a subexpression should be matched. Expressions in this extension describe the ...
A Note on Exact Algorithms for Vertex Ordering Problems on Graphs
In this note, we give a proof that several vertex ordering problems can be solved in O ∗(2 n ) time and O ∗(2 n ) space, or in O ∗(4 n ) time and polynomial space. The algorithms generalize algorithms for the Travelling ...

Similarity-based Exploded Views
Exploded views are often used in illustration to overcome the problem of occlusion when depicting complex structures. In this paper, we propose a volume visualization technique inspired by exploded views that partitions ...
A Type System for Usage of Software Components
The aim of this article is to support component-based software engineering by modelling exclusive and inclusive usage of software components. Truong and Bezem describe in several papers abstract languages for component ...
Solving the pooling problem with LMI relaxations
(The authors, 2012)
We consider the standard pooling problem with a single quality parameter, which is a polynomial global optimization problem occurring among other places in the oil industry. In this paper, we show that if the feasible ...
Building Trust in Remote Internet Voting
(The University of Bergen, 2010-05-27)
During the past decades, a lot of research has been done to create voting protocols and election systems that facilitate voting via the Internet. Many universities and private organizations are now using such systems for ...
The male germ cell gene regulator CTCFL is functionally different from CTCF and binds CTCF-like consensus sites in a nucleosome composition-dependent manner
(BioMed Central, 2012-06-18)
<p>Background: CTCF is a highly conserved and essential zinc finger protein expressed in virtually all cell types. In conjunction with cohesin, it organizes chromatin into loops, thereby regulating gene expression and ...
