CREATING, VISUALIZING AND SHARING HIGH-POLY AND MULTI-TEXTURES MODELS ON THE WEB
Texture Mapping High-resolution Mesh Web Sharing WegGL Web Information System
2019/3/4
In many Cultural Heritage cases study, where usually the shapes to be reproduced have complex and irregular geometries there is a growing demand to create and use very high-resolution polygonal models...
A command for estimating spatial-autoregressive models with spatial-autoregressive disturbances and additional endogenous variables
spivreg spatial-autoregressive models
2015/9/24
We describe the spivreg command, which estimates the parameters
of linear cross-sectional spatial-autoregressive models with spatial-autoregressive
disturbances, where the model may also contain add...
Computing Optimal Uncertainty Models from Frequency Domain Data
Computing Optimal Uncertainty Models Frequency Domain Data
2015/7/10
Uncertainty models are an essential ingredient in robust control design. In addition, because of the tradeoff between uncertainty and performance, the uncertainty model should be as ‘tight’ as possibl...
Segmentation of ARX-Models Using Sum-of-Norms Regularization
Segmentation Regularization ARX-models
2015/7/9
Segmentation of time-varying systems and signals into models whose parameters are piecewise constant in time is an important and well studied problem. It is here formulated as a least-squares problem ...
A Distributed Algorithm for Fitting Generalized Additive Models
Convex optimization Distributed optimization Generalized additive models
2015/7/9
Generalized additive models are an effective regression tool, popular in the statistics literature, that provide an automatic extension of traditional linear models to nonlinear systems. We pres...
Principal components analysis (PCA) is a well-known technique for approximating a data set represented by a matrix by a low rank matrix. Here, we extend the idea of PCA to handle arbitrary data sets c...
Unbiased Estimation with Square Root Convergence for SDE Models
Unbiased Estimation Square Root Convergence SDE Models
2015/7/6
In many settings in which Monte Carlo methods are applied, there may be no known algorithm for exactly generating the random object for which an expectation is to be computed. Frequently, however, one...
Applying Random Coefficient Models to Strategy Research:Testing for Firm Heterogeneity,Predicting Firm-Specific Coefficients,and Estimating Strategy Trade-Offs
Strategy Mathematical Methods
2015/4/27
Although Strategy research aims to understand how firm actions have differential effects on performance, most empirical research estimates the average effects of these actions across firms. This paper...
Business Model Innovation and Competitive Imitation: The Case of Sponsor-Based Business Models
Business Model Innovation and Invention Market Entry and Exit Competitive Strategy Competitive Advantage Value
2015/4/23
We study sponsor-based business model innovations where a firm monetizes its product through sponsors rather than setting prices to its customer base. We analyze strategic interactions between an inno...

We provide a preference framework for situations in which \intentions matter." A
behavioral type describes the individual's observable characteristics and the individual's
personality. We deˉne a ca...

2014/7/3
When people speak about "business models," they could be speaking about three distinct things: components of business models, real operating business models, and what we call change models. A business...
A Critical Analysis of Measurement Models of Export Performance
export performance international business construct validation
2009/9/25
Poor conceptualization of the export performance construct may undermine theory development efforts and may be one of the reasons behind the often conflicting findings in empirical research on the exp...
