A Multirate, Multiscale Economic Model Predictive Control Approach for Velocity Trajectory Optimization of a Heavy Duty Truck
JOURNAL OF DYNAMIC SYSTEMS MEASUREMENT AND CONTROL-TRANSACTIONS OF THE ASME, 143(3).
TL;DR:
This paper introduces a hierarchical economic model predictive control approach for maximizing the fuel economy of a heavy-duty truck, which simultaneously accounts for aggregate terrain changes that occur over very long length scales, fine terrain changes which occur over shorter length scale, and lead vehicle behavior that can vary over much shorter time/length scales.

Toward Quantifiable Evidence of Excess' Value Using Personal Gaming Desktops
Long, D., Morkos, B., & Ferguson, S. (2021, March 1). JOURNAL OF MECHANICAL DESIGN, Vol. 143.
author keywords: excess; value; requirements modeling; uncertainty; technology forecasting; design evaluation; systems design
TL;DR:
The argument that engineers (and end-users) should embrace strategic inefficiencies—even though they might never be used—is strengthened, and evidence is provided that excess can improve end-user system value when future requirements are unknown.

Isolating the energetic and mechanical consequences of imposed reductions in ankle and knee flexion during gait
JOURNAL OF NEUROENGINEERING AND REHABILITATION, 18(1).
author keywords: Biomechanics; Gait; Ankle; Knee; Metabolic cost
MeSH headings : Adaptation, Physiological / physiology; Adult; Ankle; Ankle Joint / physiology; Biomechanical Phenomena; Female; Gait / physiology; Humans; Knee Joint / physiology; Male; Range of Motion, Articular / physiology; Walking; Young Adult
TL;DR:
As expected, reduced ankle motion, either without ( restricted-ank) or in addition to knee restriction (restricted-a + k) yielded significant increase in net metabolic rate when compared with the braced condition, and the relative increase in metabolic cost was significantly larger with restricted-a'+’k when compared to restricted-knee condition.

Centrifugal Detachment of Compound Droplets from Fibers
LANGMUIR, 37(2), 928–938.
Contributors: H. Holweger*, M. Jamali n & H. Tafreshi n
TL;DR:
This article presents the first experimental-computational study on the centrifugal detachment of a compound droplet (e.g., a primary water droplet cloaked by an immiscible oil) from a fiber and defines effective interfacial tensions and contact angles for detaching compound droplets, for the first time.
