Been Set Free: A Distributed Virtual Theatre Dance Performance

For Frameless 2021, we present a fully realized example of virtual theatre. We define virtual theatre as a live theatrical performance, experienced on a stage in virtual reality, with participants in different physical locations (Geigel 2018)

A REVIEW AND EVALUATION OF WEATHER-CROP YIELD MODELS

The purpose of this paper is the relatively limited one of reviewing the literature for models which develop specific relationships between climatic variables and crop yields. Following a review of recent weather-crop yield modeling efforts we evaluate these models and suggest some conceptual models and data base improvements if we are to adequately project the impacts on crop production of expected future climatic change. Our review and evaluation centers on weather-crop yield models applicable to the central grain belt of the U.S., mainly the Corn Belt and Great Plains production regions.Crop Production/Industries,

An econometric analysis of family labor supply decisions and household incomes: U.S. rural farm and nonfarm households, 1978-82

The objectives of this study are (1) to develop a general model of farm and rural nonfarm household behavior that explains how labor supply and labor participation decisions are made by rural married couple households, and (2) to develop econometric models of labor demand, labor supply, labor participation and household income for rural nonfarm households and of off-farm labor participation and household income for farm households;The econometric models are fitted to micro data sets on households obtained by combining together household and individual data in the Current Population Survey for 1978, 1979, 1981, and 1982. These variables on households are augmented by state-level labor market and farm-profitability variables matched to households by state of residence;The work-not work decisions of husbands and wives are modeled jointly in a household decision-making context. The bivariate analysis of their wage labor participation decisions takes into account the correlation of disturbance terms across husband\u27s and wife\u27s participation equations. The cross equation correlation was found to be statistically significant and positive for both types of households but to be larger for husbands and wives in farm households. Predicted probabilities from the bivariate labor participation equations were used to construct estimates of sample selection terms for the labor demand and labor supply equations of the rural nonfarm husbands and wives;For rural nonfarm households, schooling, experience and local labor market variables, especially the unemployment rate, state average manufacturing wages, and the change in the percentage of service jobs, are shown to have significant effects on labor participation decisions and household incomes. For farm households, schooling, experience and local climatic conditions have significant effects on the probability of wage work participation of couples and household income. Local labor market variables and indicators of farm profitability had relatively weak effects on off-farm work participation and farm household incomes. Estimated rates of return to husbands\u27 and wives\u27 education are higher for rural nonfarm households than for farm households, and the return on husbands\u27 and wives\u27 schooling (effect on household income) are not significantly different

Unsupervised Learning Trojan

This work presents a proof of concept of an Unsupervised Learning Trojan. The Unsupervised Learning Trojan presents new challenges over previous work on the Neural network Trojan, since the attacker does not control most of the environment. The current work will presented an analysis of how the attack can be successful by proposing new assumptions under which the attack can become a viable one. A general analysis of how the compromise can be theoretically supported is presented, providing enough background for practical implementation development. The analysis was carried out using 3 selected algorithms that can cover a wide variety of circumstances of unsupervised learning. A selection of 4 encoding schemes on 4 datasets were chosen to represent actual scenarios under which the Trojan compromise might be targeted. A detailed procedure is presented to demonstrate the attack\u27s viability under assumed circumstances. Two tests of hypothesis concerning the experimental setup were carried out which yielded acceptance of the null hypothesis. Further discussion is contemplated on various aspects of actual implementation issues and real world scenarios where this attack might be contemplated

Experimental Analysis of Spatial Sound for Storytelling in Virtual Reality

Virtual Reality leverages our cognitive and perceptual abilities to provide immersive experiences that recreate both the visual and aural elements of real spaces with a high degree of realism making it a suitable delivery platform for conveying narratives through games and films. Spatial sound is useful in enhancing immersion and presence of the user in a virtual world. This audio design allows the game designer to place audio cues that appropriately match with the visual cues in a virtual game environment. These localized audio cues placed in a story based game environment also help to evoke an emotional response from the user and construct the narrative of the game by capturing the user’s attention towards the guiding action events in the game. Our work currently involves a thorough literature study on the significance of debating the usefulness of spatial sound. Our future work involves conducting a user study for analyzing the same i.e., understanding how spatial sound improves user performance and user experience in a virtual game environment. Furthermore, with the help of the relevant subjective and objective inferences that will be collected from the user study conducted on four different evaluation models, our work will also analyze and establish the potential of spatial sound as a powerful storytelling tool in a virtual game environment
