The ability to model 3D objects from monocular video allows for a number of very useful applications, for instance: 3D face recognition, fast prototyping and entertainment. At present there are a number of methods available for 3D modelling from this and similar data. However many of them are either not robust when presented with real world data, or tend to bias their results to a prior model. ...

Overview Most of the books on data warehousing and business analysis automation are typically concerned with technical issues. Certain books also attempt to describe the overall organization of a data warehousing project – a challenging process that usually requires extraordinary skills and significant efforts. But there is the vital element of data warehousing methodology that makes DWs valuab...

Robot navigation in poorly structured and uneven outdoor environments is an unsolved problem. Thus we present a SLAM (simultaneous localization and mapping) approach that is based on “leveled range scans”. The method is combining 3D perception with 2D localization and mapping. In this way established path planning and 2D navigation algorithms can be used in uneven terrain without the computatio...

We present a linear three-dimensional modeling paradigm for lips and face, that captures the audiovisual speech activity of a given speaker by only six parameters. Our articulatory models are constructed from real data (front and profile images), using a linear component analysis of about 200 3D coordinates of fleshpoints on the subject's face and lips. Compared to a raw component analysis, our...

Motivated by contact resistance on the front side of a crystalline silicon solar cell, we formulate and analyse a two-dimensional mathematical model for electron flow across a poorly conducting (glass) layer situated between silver electrodes, based on the driftdiffusion (Poisson-Nernst-Planck) equations. We devise and validate a novel spectral method to solve this model numerically. We find th...

Three-dimensional modeling of geological bodies is a useful tool for multiple applications. Such tasks are usually accomplished starting from fieldcollected data, which typically suffer from intrinsic limitations such as accessibility constraints and punctuality of data collected. In this work, we explore the reliability of photo-geological mapping from interpretation of aerial photographs in p...

Lateral current injection (LCI) lasers are promising candidates for optoelectronic integration and novel functional devices. We investigate experimentally the performance of a new class of LCI lasers with improved operating characteristics, focusing in particular on regions of agreement and disagreement with our physical model. We then employ fully selfconsistent two-dimensional modeling in ord...

Poro-mechanical, thermal, and chemical processes can play a significant role when developing enhanced geothermal systems. These processes occur on various time scales and the significance of their interaction varies with the problem of interest. Of particular importance is the thermo-mechanical coupling during injection operations (time scale of months/years). In fact, the phenomena of the vari...

Classical dimensional modeling aims for simple data warehouse designs in order to make the job of the end user and the DBMS easier. This paper describes a different approach aimed at simplifying data extraction, transformation, and loading tasks. Our design approach avoids and isolates changes to source data tables by surrounding them with helper-views. Each helper-view specializes in a single ...
