Robust Lattice Alignment for K-user MIMO Interference Channels with Imperfect Channel Knowledge
, 2011 In this paper, we consider a robust lattice alignment design for K-user quasi-static MIMO interference channels with imperfect channel knowledge. With random Gaussian inputs, the conventional interference alignment (IA) method has the feasibility problem

Nucleic Acids Research, 1984 We show how to speed up sequence alignment algorithms of the type introduced by Needleman and Wunsch (and generalized by Sellers and others). Faster alignment algorithms have been introduced, but always at the cost of possibly getting sub-optimal alignments.

Ancestral sequence alignment under optimal conditions [PDF]
BMC Bioinformatics, 2005 Abstract Background Multiple genome alignment is an important problem in bioinformatics. An important subproblem used by many multiple alignment approaches is that of aligning two multiple alignments. Many popular alignment algorithms for DNA use the sum-of-pairs heuristic, where the score of a multiple alignment is the ...

Gradient Descent Optimization-Based SINS Self-Alignment Method and Error Analysis
IEEE Access, 2021 In this paper, the self-alignment for stationary strapdown inertial navigation system (SINS) is formulated as an optimization problem, and two gradient descent optimization-based SINS self-alignment methods (GD1 and GD2) are proposed.

Evaluation of Trace Alignment Quality and its Application in Medical Process Mining
, 2017 Trace alignment algorithms have been used in process mining for discovering the consensus treatment procedures and process deviations. Different alignment algorithms, however, may produce very different results.

A possible solution of the grain boundary problem for applications of high-Tc superconductors
, 2002 It is shown that the critical current density of high-Tc wires can be greatly enhanced by using a threefold approach, which consists of grain alignment, doping, and optimization of the grain architecture.

Distribution on Warp Maps for Alignment of Open and Closed Curves [PDF]
, 2019 Alignment of curve data is an integral part of their statistical analysis, and can be achieved using model- or optimization-based approaches. The parameter space is usually the set of monotone, continuous warp maps of a domain.

Visualization of near-optimal sequence alignments [PDF]
Bioinformatics, 2004 Abstract Motivation: Mathematically optimal alignments do not always properly align active site residues or well-recognized structural elements. Most near-optimal sequence alignment algorithms display alternative alignment paths, rather than the conventional residue-by-residue pairwise alignment.

Optimal molecular alignment and orientation through rotational ladder climbing
, 2005 We study the control by electromagnetic fields of molecular alignment and orientation, in a linear, rigid rotor model. With the help of a monotonically convergent algorithm, we find that the optimal field is in the microwave part of the spectrum and acts
