This study offers a novel empirical equation for those involved in ski-jump type energy dissipator, stilling basin, and plunge pool designs to determine the dissipation level due air resistance. The verified by conducting experimental, empirical, numerical regression analyses at prototype scale. Energy resistance can then be easily calculated discharges reaching up 10000 m3/s using equation.

Abstract— The ICT4S Green Hackathon was an event exploring the use of information and communications technologies in sustainable food production and consumption, where developers, designer and problem owners met for creating prototypes and applications for a whole d...

This paper describes the Orbit Scheme optimizing compiler. Orbit was one of the first practical compilers for Scheme, whereas most existing Scheme compilers at the time were research prototypes. The paper walks us through the phases of the compiler, explaining design decisions along the way. The result of this research is a production-quality Scheme compiler. It generates code that is competiti...

The demand for flow visualization software stems from the popular (and growing) use of Computational Fluid Dynamics (CFD) and the increasing complexity of simulation data. CFD is popular with manufacturers as it reduces cost and the time of production relative to the expense involved in creating a real physical model. Modifications to a physical model to test new prototypes may be non-trivial a...

Bicycle production has not changed much over the last 100 years, it is still performed mainly by manual labor in mass production. During global pandemic, demand for ecologically friendly and customized transport increased. Hence, customers start to impose same requirements on bikes as cars: they want more products short delivery time. This publication describes an approach transform bicycle man...

OBJECTIVES There is still limited understanding of how different kinds of drinker prototypes are associated with adolescent drinking. This study uses the strengths of multiple time-point diary measures (enhanced validity of alcohol use measurement) to test the predictive value of abstainer, moderate and heavy drinker prototypes in social situations. We examined whether the favorability of these...

Quantum Information Science (QIS) is in its infancy and quantum computers are currently at an experimental stage. No production system exists and, while small prototypes are being tested in laboratories (using a few “qubits”), we may not see such reality for another 10 or 20 years. The challenge is that, while we do understand the underlying theoretical physics, the engineering needed to build ...
