This paper proposes that to understand various issues concerning tune-text alignment, three levels of timing relations need to be recognized, namely, underlying association, target synchronization, and surface alignment. While the link between underlying association and target synchronization may be stipulated by various phonological rules, the link between surface alignment and target synchron...

In this thesis, the degrees of freedom (DOF) of wireless networks are studied with imperfect channel state information at transmitters (CSIT) and/or secrecy constraints. Different interference alignment schemes are proposed to establish the DOF lower bound for a variety of wireless networks. For the imperfections of CSIT, we mainly have two practical concerns. The first concern is the long dela...

This paper is concerned with some feasibility issues in mathematical programs with equilibrium constraints (MPECs) where additional joint constraints are present that must be satis ed by the state and design variables of the problems. We introduce su cient conditions that guarantee the feasibility of these MPECs. It turns out that these conditions also guarantee the feasibility of the quadratic...

Word-level alignment of bilingual text is a critical resource for a growing variety of tasks. Probabilistic models for word alignment present a fundamental trade-off between richness of captured constraints and correlations versus efficiency and tractability of inference. In this article, we use the Posterior Regularization framework (Graça, Ganchev, and Taskar 2007) to incorporate complex cons...

bioinformatics, through the sequencing of the full genomes for many species, is increasingly relying on efficient global alignment tools exhibiting both high sensitivity and specificity. many computational algorithms have been applied for solving the sequence alignment problem. dynamic programming, statistical methods, approximation and heuristic algorithms are the most common methods applied t...

OBJECTIVES To analyse the first four rounds of country applications to the GAVI Alliance Health Systems Strengthening (GAVI-HSS) funding window; to provide valuable insight into how countries prioritize, articulate and propose solutions for health system constraints through the GAVI-HSS application process and to examine the extent to which this process embodies alignment and harmonization, Pri...

Segmentation of femurs in Anterior-Posterior x-ray images is very important for fracture detection, computer-aided surgery and surgical planning. Existing methods do not perform well in segmenting bones in x-ray images due to the presence of large amount of spurious edges. This paper presents an atlas-based approach for automatic segmentation of femurs in x-ray images. A robust global alignment...
