26 Kirby, Robert MichaelVerifying volume rendering using discretization error analysisWe propose an approach for verification of volume rendering correctness based on an analysis of the volume rendering integral, the basis of most DVR algorithms. With respect to the most common discretization of this continuous model (Riemann summation), we make assumptions about the impact of parame...2014-01-01
27 Bronson, Jonathan RichardLattice cleaving: a multimaterial tetrahedral meshing algorithm with guaranteesWe introduce a new algorithm for generating tetrahedral meshes that conform to physical boundaries in volumetric domains consisting of multiple materials.

28 Khan, Faisal HabibMaximum power point tracking of stirling generator and ocean wave energy conversion systems using a two-stage power converterWave energy has become one of the most promising renewable energy resources nowadays. By using a linear generator/alternator, the periodic piston motion of the wave energy conversion system (WEC) can be converted to AC voltage with variable RMS amplitude and frequency; this process is comparable to ...2013-01-01
29 Harman, Todd B.Multiscale modeling of accidental explosions and detonationsAccidental explosions are exceptionally dangerous and costly, both in lives and money.

36 Couldwell, William T.Intracranial hypotension in the setting of concurrent perineural cyst rupture and subarachnoid hemorrhageAlthough most patients with intracranial hypotension typically present with headaches, the rest of the clinical spectrum is characteristically non-specific and often quite variable. In a patient with concurrent pathologies that can produce a similar clinical picture, a high index of suspicion must b...2013-01-01
37 Wen, MingResidential racial composition and black-white obesity risks: differential effects of neighborhood social and built environmentThis study investigates the association between neighborhood racial composition and adult obesity risks by race and gender, and explores whether neighborhood social and built environment mediates the observed protective or detrimental effects of racial composition on obesity risks. Cross-sectional d...2014-01-01
38 Balasubramonian, RajeevQuantifying the relationship between the power delivery network and architectural policies in a 3D-stacked memory deviceMany of the pins on a modern chip are used for power delivery. If fewer pins were used to supply the same current, the wires and pins used for power delivery would have to carry larger currents over longer distances. This results in an "IR-drop" problem, where some of the voltage is dropped across t...2013-01-01
39 Hibler, Michael J.Isolation of malicious external inputs in a security focused adaptive execution environmentReliable isolation of malicious application inputs is necessary for preventing the future success of an observed novel attack after the initial incident.
