Minimal surfaces in circle bundles over Riemann surfaces
, 2009 For a compact 3-manifold $M$ which is a circle bundle over a compact Riemann surface $\Sigma$ with even Euler number $e(M)$, and with a Riemannian metric compatible with the bundle projection, there exists a compact minimal surface $S$ in $M$.

Abstract and Applied Analysis, 2013 We create some new ideas of mappings called quasi-strict f-pseudocontractions. Moreover, we also find the significant inequality related to such mappings and firmly nonexpansive mappings within the framework of Hilbert spaces.

On paraquaternionic submersions between paraquaternionic K\"ahler manifolds
, 2008 In this paper we deal with some properties of a class of semi-Riemannian submersions between manifolds endowed with paraquaternionic structures, proving a result of non-existence of paraquaternionic submersions between paraquaternionic K\"ahler non ...

Moisture Metrics Project [PDF]
, 2011 the goal of this project was to determine the optimum moisture levels for biomass processing for pellets commercially, by correlating data taken from numerous points in the process, and across several different feedstock materials produced and harvested using a variety of different management practices.

Journal of Approximation Theory, 1995 Let \(E\) denote a normed vector space, and \(M\hookrightarrow E\) a vector subspace. If \(P_M: E\to M\) denotes the metric projection, then trivially \(|P_M|\leq 2\). Moreover, \(|P_M|\leq 1\) for every vector subspace \(M\hookrightarrow E\) if and only if \(E\) is a pre-Hilbert space. In the paper under review, the authors establish that for a Banach

Informative Data Projections: A Framework and Two Examples [PDF]
, 2015 Methods for Projection Pursuit aim to facilitate the visual exploration of high-dimensional data by identifying interesting low-dimensional projections. A major challenge is the design of a suitable quality metric of projections, commonly referred to as ...

Face recognition in different subspaces - A comparative study [PDF]
, 2006 Face recognition is one of the most successful applications of image analysis and understanding and has gained much attention in recent years. Among many approaches to the problem of face recognition, appearance-based subspace analysis still gives the ...

, 2014 The aim of this deliverable is to provide project-wide metrics to track the progress and impact of BioMedBridges. There are different areas in the project that offer themselves to performance measurement via different, specific types of metrics: Grant fulfilment Technical metrics (data and services, tools, standards) Knowledge output and ...
