We ran a Lagrangian stochastic (LS) dispersion model in both forward-in-time and backward-in-time ways to derive footprints. Three Eulerian analytical footprint models were compared with this Lagrangian model for a wide atmospheric stability range. Despite some differences among the three analytical footprint models, their results generally agreed. Results from the forward LS simulations agreed...

[Purpose] The purpose of this study was to evaluate the effects of stair walking training on balance ability of chronic stroke patients. [Subjects and Methods] Forty stroke patients were allocated equally and randomly to an experimental group and a control group. The experimental group undertook 30 minutes of training therapy and 30 minutes of walking exercise on stairs with flat surfaces. The ...

Security in every real time applications is of utmost importance. The secure architecture implemented in the automobiles such as EVITA (E-safety Vehicle Intrusion protected Application), SEVECOM (Secure Vehicle Communication) has rich cryptographic properties, but has more footprint area and high power consumption. This existing architecture uses standard engines like AES (Advanced encryption s...

One of the main advantages of the Gantry-Tau machine is a large accessible workspace/footprint ratio compared to many other parallel machines. The Gantry-Tau improves this ratio by allowing a change of assembly mode without internal link collisions or collisions between the links and the moving TCP platform. This paper introduces the geometric approach for the unreachable workspace area for the...

A reconfigurable mechanism for varying the footprint of a four-wheeled omnidirectional vehicle is developed and applied to wheelchairs. The variable footprint mechanism consists of a pair of beams intersecting at a pivotal point in the middle. Two pairs of ball wheels at the diagonal positions of the vehicle chassis are mounted, respectively, on the two beams intersecting in the middle. The ang...

Large hydropower project (LHP) is now the most important renewable and low-carbon source for electricity generation, carbon footprint calculation is crucial for it. We established an embodied carbon budget accounting system for LHP to calculate its actual carbon footprint. In additional to traditional carbon emission from plant construction, the accounting system included two new items in the c...

The global nitrogen (N) cycle has been transformed by human use of reactive N as a consequence of increased demand for food and energy. Given the considerable impact of humans on the N cycle, it is essential that we raise awareness amongst the public and policy makers as this is the first step in providing individuals and governments the opportunity to reduce their impact on the N cycle and red...
