Hyperproduction : an audio-centric framework for the abstract modeling of live performance to guide audience attention and perspective using connected real-time systems
Hyperproduction is a conceptual framework and a software toolkit which allows producers to specify a descriptive computational model and consequently an abstract state for a live experience through traditional operating paradigms such as mixing audio, operation of lighting, sound or video systems. …

Value of Cultural Practices for Improving Nitrogen Management in Corn
Production and profitability of corn (Zea mays L.) is highly dependent on fertilizer nitrogen (N) use. The efficiency of fertilizer N use and the capacity of the soil to supply N are the two main components determining the corn N requirement. The cropping management system can also affect N use …
