ScalaBison is a parser generator accepting bison syntax and generating a parser in Scala. The generated parser uses the idea of “recursive ascent-descent parsing,” that is, directly encoded generalized left-corner parsing. Of interest is that fact that the parser is generated from the LALR(1) tables created by bison, thus enabling extensions such as precedence to be handled implicitly.

Abstract The emergence of risk-based capital regulation that is allowing banks to use their internal risk models for regulatory purposes was among the main developments prior financial crisis. During crisis, it became evident these underestimated level risk. post-crisis approach brought a reversal policy by significantly reducing scope and making regulations less risk-sensitive. At first glance...

Mesoscale eddies play an important role in regulating the global ocean ecosystem and climate variability. However, few studies have been found to focus on survey of underwater gliders (UGs) motion performance inside mesoscale eddies. The dynamic model UG considering eddy density is established predict its eddy. Ignoring effect vertical velocity UG, simulation results experimental data are compa...

This paper introduces the concept of a steepest ascent tariff reform for a small open economy. By construction, it is locally optimal in that it yields the highest gain in utility of any feasible tariff reform vector of the same length. Accordingly, it provides a convenient benchmark for the evaluation of the welfare effectiveness of other tariff reform proposals. We develop the properties of t...

BACKGROUND Few studies have reported the biomechanical aspects of stair climbing for this ergonomically demanding task. The purpose of this ethically approved study was to identify normal functional parameters of the lower limb during stair climbing and to compare the actions of stair ascent and descent in young healthy individuals. METHODS Thirty-three young healthy subjects, (16 M, 17 F, ra...

PURPOSE This study compared the kinematics and kinetics of the knee joint during traditional step-over-step (SOS) and compensatory step-by-step lead-leg (SBSL) and trail-leg (SBST) stair ambulation patterns. METHODS Seventeen (M:9) healthy adults completed five trials of ascent and descent using three different stepping patterns: 1) SBSL, 2) SBST, and 3) SOS. Kinematics and kinetics were coll...

Individuals with anterior cruciate ligament (ACL) reconstruction are at increased risk to develop knee osteoarthritis (OA). Gait analysis describing kinetics of the lower extremity during walking and stair use (stair ascent and stair descent) can provide insight to everyday dynamic knee joint loading. In this study, we compared lower extremity gait patterns of those with ACL reconstruction (>1 ...
