Co-production of Science and Regulation: Radiation Health and the Linear No-Threshold Model
The model used as the basis for regulation of human radiation exposures in the United States has been a source of controversy for decades because human health consequences have not been determined with statistically meaningful certainty for the dose levels allowed for radiation workers and the …

An Algorithm for Influence Maximization and Target Set Selection for the Deterministic Linear Threshold Model
… maximization under the deterministic linear threshold model and presents a novel heuristic for finding influential nodes in a graph with the goal of maximizing contagion spread that emanates from these influential nodes. Inputs to our algorithm include edge weights and vertex thresholds. The …

Validating and Refining a Locally Developed Universal Screening System in High School Mathematics
… between at-risk and non-at-risk students. The threshold model is an identification model that excludes students with a low probability of failure from intervention, includes students with a high probability of failure in intervention, and requires additional information for those with no clear …

Graph methods in Multi Agent Systems Coordination and Social Network Analysis
… Social Network according to the so called Linear Threshold Model, in which the innovation is incepted in the network starting from a seed set, and nodes adopt the innovation if the ratio of the neighbours that have already adopted it is greater than or equal a certain threshold value. We focus on …

Models of the auditory threshold
… procedure in conjunction with an automatic threshold seeking method is selected for detailed study. Sequential strategies and decision rules for the location of specific points on a psychometric function are introduced as the basis of the automatic threshold seeking method. To aid in the …

Depth and orbital tuning : a new chronology of glaciation and nonlinear orbital climate change
… to orbital variations. By developing a new age-model, independent of orbital assumptions, a significant non-linear response to orbital forcing becomes evident in the [delta] 18 0 record. The new age-model also indicates glacial terminations two through eight are 8,000 years older than the …

EXTENDED LEARNING TIME THROUGH AFTERSCHOOL PROGRAMS:
… time was analyzed through attendance. The threshold model (Marsh & Kleitman (2002) guided the relational analyses and found a strong to minimal relationship between attendance and grades (GPA) in six of the sixteen scatter plots. The parent and staff survey results support the need for a …

Comparison Of Four Models For Predicting Person Reliability
… research was to examine the efficacy of four models for predicting person reliability, which was defined as across-session item consistency. Two prediction models were based on item characteristics alone, namely, p-values and social desirability scale values. Two prediction models attempted to …

A Morphological and Phylogenetic Comparative approach to investigating Branching Architecture Evolution in Monocots A Dissertation
… role in the diversification of monocots. The models in the aforementioned approach are based largely on models of nucleotide substitution for discrete states. The third chapter seeks to achieve a more realistic understanding of branching architecture evolution by incorporating morphospaces …

Multisensory models for human spatial orientation including threshold effects
… a stand-alone executable version of the Observer model developed by Newman and Oman (2009), was developed. The complicated structure of the Observer model and its parameters made this conversion challenging. The resulting Windows PC executable uses a publically available library (MATLAB component …

Optimal Management of a Common Property Pest Under Risk: An Application to the Corn Rootworm
An integrated pest management model is developed for the northern corn rootworm, Diabrotica longicornis, and the western corn rootworm, Diabrotica virgifera, insect pests of corn. Uncertainty and risk aversion are incorporated into an economic threshold model. Two control actions, soil insecticide …

Problems in Pedigrees and Phylogenies
… ordinal outcome trait. We discuss the use of the threshold model for heritability estimation, exploring the consequences of model misspecification and sample size requirements under this model. Next, we move to phylogenetic methods for the detection of recombination, or the exchange of genetic …

Belief propagation analysis in two-player games for peer-influence social networks
… in Afghanistan. A discrete time, agent-based threshold model is developed to analyze the propagation of beliefs in the social network, whereby each agent has a belief and a threshold value, which indicts the willingness to be influenced by the peers. Agents communicate in stochastic pairwise …

Intertwined evolution of swimming, morphology and microhabitat in tree frogs from the subfamily Hylinae
… of traits along the phylogeny by using the threshold model. I found that Hylinae species use the two types of swimming reported for frogs, alternating gait (considered the primitive condition in frogs) and simultaneously gait (the derived mode). In addition, there is a high rate of inter- …

Acceleration-Based Gesture Recognition for Conducting with Hidden Markov Models
… Bluetooth to the host computer. Hidden Markov models are chosen to perform the gesture recognition task. While realizing a reliable and continuous gesture recognition, the proposed system is able to successfully reject non-meaningful hand movements, applying a threshold model. The system makes …

Differential and numerical models of hysteretic systems with stochastic and deterministic inputs
Many deterministic models with hysteresis have been developed in the areas of economics, finance, terrestrial hydrology and biology. These models lack any stochastic element which can often have a strong effect in these areas. In this work stochastically driven closed loop systems with hysteresis …
