Signal Processing Demo: A web based interactive simulation tool for Continuous-Time Signals and Systems

Continuous Signals and System classes are often taught through a very theoretical approach. This approach entails large mathematical derivations of complex concepts, without applying practical hands on application of how the underlying math affects real world situations. To assist in the theoretical content, showcasing the application of the classroom theory, a web-based simulation tool was developed using MATLAB’s App Designer Toolbox. This simulation tool covers some of the foundational fundamentals in continuous-time signals and systems classes, such as frequency spectrum analysis, amplitude modulation/demodulation and the impacts of filtering

Subjective Mortality Risk and Bequests

This paper investigates whether subjective expectations about future mortality affect consumption and bequests motives. We estimate a dynamic life-cycle model based on subjective survival rates and wealth from the panel dataset Asset and Health Dynamics among Oldest Old. We find that bequest motives are small on average, which indicates that most bequests are involuntary or accidental. Moreover, parameter estimates using subjective mortality risk perform better in predicting out-of-sample wealth levels than estimates using life table mortality risks, suggesting that decisions about consumption and saving are influenced more strongly by individual-level beliefs about mortality risk than by group level mortality risk.

Targeting the profits of illicit drug trafficking through proceeds of crime action

This study sought to identify the disruptive effect of proceeds of crime action on criminal activity, and to identify factors associated with successful proceeds of crime action. Executive summary Illicit drug trafficking is a source of funds for further trafficking and for supporting the lifestyles of criminals. Drug trafficking has been closely linked with organised crime and with social harms. This project had two main aims: • To identify the disruptive effect of proceeds of crime action on criminal activity. The project attempted to measure the disruptive effect by developing an economic model that estimated the multiplier impact of the reinvestment of the profits of drug trafficking. • The project also attempted to identify factors associated with successful proceeds of crime action. There are two main audiences for the findings of this study. Senior police, police intelligence, policymakers and researchers will be interested primarily in measuring the disruptive effect of proceeds of crime action. Police responsible for managing proceeds of crime investigations and senior investigators will be interested in the practical applications of findings relating to success factors in financial investigations. The results of the project should improve agencies’ ability to target trafficking and increase the seizure of proceeds of crime. The proposed index of the disruptive effect of proceeds of crime action—the Proceeds of Crime Drug Disruption Index (POCDDI)—will also allow agencies to provide both the Government and the community with a more accurate assessment of the value of their proceeds of crime initiatives

How a National Carbon Policy Could Affect Grain Variety Selection: The Case of Rice in Arkansas

This study conducts a life cycle assessment (LCA) of carbon emissions and estimates the carbon sequestered in 14 commonly sown rice varieties across the Arkansas Delta. Given the uncertainty regarding future carbon legislation, and increased consumer and industry demand for “greener” products, this study estimates how potential carbon policies would affect rice cultivar selection Hybrid rice varieties, given their higher yield and higher yield per unit of green house gas (GHG) emission, are better positioned to take advantage of any increase in consumer demand for “greener” products and/or absorb any government policy better than conventional rice cultivars.Rice, Carbon Policy, Cap and Trade, Carbon Offset, Agricultural and Food Policy, Crop Production/Industries, Environmental Economics and Policy, Q52, Q54, Q58,
