"Collaborative filtering algorithms’ performances have been evaluated using a variety of metrics.
These metrics, such as Mean Absolute Error and Precision, have often ignored recommendations for
which they do not have data. Ignoring these recommendations has provided numbers which do not
accurately represent the user experience. Qualitatively we have seen...
Farm machinery continues to increase in its importance to the agricultural sector. Depreciation, the decline in value of a durable asset over time, represents one of the largest costs of agricultural production. The general objectives of this study were to update and expand the number of Remaining Value (RV) functions...
This project aims at building a Java application and a Java applet that would simulate a Stern-Gerlach laboratory in Quantum Mechanics. The project provides a tool for allowing the student to quickly design and run on the computer screen a number of experiments involving spin systems. This application could be...
This thesis presents a model for simulating individual pedestrian motion based on empirical data. The model keeps track of a pedestrian’s position, orientation, and body configuration and leverages motion capture data to generate plausible motion. Our model can automatically incorporate a pedestrian’s physical limitations when making movement decisions, since it...
Functional programming is concerned with referential transparency, that is, given a certain function and its parameter, that the result will always be the same. However, it seems that this is violated in applications involving uncertainty, such as rolling a dice. This thesis defines the background of probabilistic programming and domain-specific...
Nonnegative matrices have a myriad of applications in the biological, social, and physical genres. Of particular importance are the primitive matrices. A nonnegative matrix, M, is primitive exactly when there is a positive integer, k, such that M[superscript k] has only positive entries; that is, all the entries in M[superscript...
In order to aid comparison of estimates of genetic parameters between dominant and codominant makers for population genetics society, we developed a genetic dominance simulation program to determine how the dominance and biallelism could affect the estimation of population genetic statistics. The simulation indicates that genetic diversities within populations based...
The new Technical Report Management System (TRMS) is a client/server web application developed for the Compute Science Department. It provides web services like online browsing, viewing, searching and online database administration including creating and modifying the existing bibliographic records. It is a multi-tiered, component-based application that deploys the latest J2EE...
The Elliptic Curve Digital Signature Algorithm (ECDSA) is a public key cryptosystem used for creation and verification of digital signatures in electronic documents. In this thesis, we created a Java applet that provides the functionality of the ECDSA using all of the NIST elliptic curves over GF(p). This applet was...
