A methodology has been developed for predicting the future growth in demand for irrigation in countries with supplemental irrigation such as England and Wales. This takes into account expected changes in agricultural policy, technical, market and other factors. The methodology has also been applied within a geographical information system (GIS) to map the growth. The GIS approach represents an ...

In the unglaciated parts of Southwestern Wisconsin, buried Terra Rossas are commonly found. These clayey, red soils are buried by loess and mainly found on ridges underlain by limestone. They have been eroded during periglacial climates. The red clay has implications for groundwater recharge as well as lateral flow through the landscape. This project focusses on a 50 km2 watershed where some 40...

Several studies have demonstrated that reward from a human trainer can be a powerful feedback signal for control-learning algorithms. However, the space of algorithms for learning from such human reward has hitherto not been explored systematically. Using model-based reinforcement learning from human reward, this article investigates the problem of learning from human reward through six experim...

FIST121 Making a Killing: Murder and True Crime Non/Fiction Narratives This course explores the genre of true crime in a comparative setting and by way of a study of different typologies of murder: spree killing, fratricide, serial killing, infanticide. Roland Barthes wrote in Mythologies that, "Periodically, some trial, and not necessarily fictitious like the one in Camus's THE STRANGER, comes...

Taking the maximum joint payoff of a 2×2 matrix game as a measure of potential social welfare, one can compute a simple “value of government” based upon the difference between this maximum payoff and the joint payoff obtained in noncooperative equilibrium. We construct an efficiency loss index (ELI) as the expected value of this difference divided by the maximum joint payoff, and use the ELI to...

Motivated by recent recommendations by both European and American accounting standards boards that executive stock options be expensed in firms’ statements, we provide an analytical and flexible framework for their evaluation. Our approach takes into account the vesting period, American style, resetting and reloading provisions that are features of many options programs, and also considers the ...

[1] We analyze the temperature anomaly of the Pinatubo eruption using an exact mathematical solution of a standard energy balance model that includes coupling between the mixed layer and the thermocline. Our solution yields a short response time t = 4.4 months and a small climate sensitivity l = 0.22 C/(W/m), implying short-term negative feedback. Also, our analysis determines a value of the ef...

A comparative study is made of the Knox-Thompson and triple-correlation techniques as applied to image restoration. Both photon-noise-degraded imaging and atmospheric-turbulence-degraded imaging are considered. The signal-to-noise ratios of the methods are studied analytically and with the aid of computer simulations. The ability to retain diffraction-limited information on imaging through turb...
