This Dissertation is a qualitative case study that examines transformative technical adaptations and organizational process changes in the context of a new product deployment in a large Telecommunications Corporation. The dissertation advances the existing body of knowledge and understanding of...

The software industry is characterized by a significant number of mergers and acquisitions and licensing transactions each year. When the driving factor for these transactions is technology acquisition, the effort to recreate the innovation by the potential licensee becomes a key variable to...

The k-Nearest-Neighbor (k-NN) pattern recognition procedure is a nonparametric method of classifying patterns based on the nearest training samples in feature space. In biometric authentication systems, the Receiver Operating Characteristic (ROC) curve is a graphical representation of the...

Social and computer networks permeate our lives. Large networks, such as the Internet, the World Wide Web (WWW), AND wireless smartphones, have indisputable economic and social importance. These networks have non-trivial topological features, i.e., features that do not occur in simple networks...

EXECUTIVE SUMMARY Undergraduate computing students often produce high quality final-year projects with a software product that has the potential to become commercially viable. It is feasible to identify such projects by enterprise-aware academic staff during the projects' development. The...

We describe a class of sparse latent factor models, called graphical factor models (GFMs), and relevant sparse learning algorithms for posterior mode estimation. Linear, Gaussian GFMs have sparse, orthogonal factor loadings matrices, that, in addition to sparsity of the implied covariance...

Strategic reasoning is part of our everyday lives: we negotiate prices, bid in auctions, write contracts, and play games. We choose actions in these scenarios based on our preferences, and our beliefs about preferences of the other participants. Game theory provides a rich mathematical framework...

Peer-to-peer systems, networks of egalitarian nodes without a central authority, can achieve massive scalability and fault tolerance through the pooling together of individual resources. Unfortunately, most nodes represent self-interested, or rational, parties that will attempt to maximize their...

Crowd analysis is of increasing interest. Sociologists, for example, are interested in studying social influence within and between small groups of individuals traveling in a crowd. However, current empirical studies conducted by human observers are very time-consuming. We propose an automatic,...
