Simulation and theoretical study of swimming and resistive forces within granular media
… the sand-swimming sandfish lizard. I developed a resistive force theory (RFT) with empirical force laws to explain the swimming speed observed in animal experiments. By varying the amplitude of the undulation in the RFT, I found that the range of amplitude used by the animal predicted the optimal …

Optimisation considerations for the measurement of human muscle power
… measure power outputs. Most of the tests utilise resistive forces that are based on total-body mass values (TBM). Conceptually, selecting an optimal resistive force based on total-body mass may not be the best approach. Resistive forces that reflect the mass of the lean tissue specifically …

Development of an automated and scalable lab-on-a-chip platform with on-chip characterization
… on an array of electrodes using electrostatic forces. In contrast to most other lab-on-a-chip technologies (e.g., channel-based microfluidics), DMF is highly reconfigurable (i.e., function is defined by software and not by the physical structure of the chips). Thus, DMF offers the possibility …

Does training with PowerCranks™ affect economy of motion, cycling efficiency, oxygen uptake and muscle activation patterns in trained cyclists?
… recruitment patterns that contribute to the resistive forces occurring during the recovery phase of the pedal stroke. However, scientific research examining the efficacy of training with PowerCranks™ is lacking. Therefore, the purpose of this study was to determine if five weeks of training …

Comparative Study of the Effect of Tread Rubber Compound on Tire Performance on Ice
… region of the drawbar-slip curve) and on the resistive forces of free-rolling tires. Modeling of the tire-ice contact for estimation of temperature rise and water film height was performed using ATIIM 2.0. The performance of this in-house model was compared against three classical tire-ice …

Reduced-order modeling of granular intrusions driven by continuum approaches
… deep insights into the origin of granular resistive forces encountered during granular intrusions. We further use these insights to extend an empirical modeling method called Resistive Force Theory (RFTs) for real-time modeling of granular intrusions. RFTs developed in this work are …

Development of an integrated tracking control algorithm and a test platform for autonomous excavation
… of the excavator. To compensate for the ground resistive forces, an impedance controller was designed. Finally, contour compensation was considered to generate an optimal path of the bucket tip by reducing the contour profile error that is vital for skilled tasks such as ground levelling. …

Limitations on tidal-in-stream power generation in a strait
… friction; the interplay between the driving and resistive forces determines the flow rate and thus the extractible power. The use of kinetic energy flux, previously employed as a metric for extractible power, is found to be unreliable as it does not account for the increased resistance the …

Effects of added drag on cetaceans : fishing gear entanglement and external tag attachment
… The energetic cost of movement depends on the resistive forces acting on an animal; changes in this force balance can occur naturally or unnaturally. Fishing gear that entangles large whales adds drag, often altering energy balance to the point of terminal emaciation. An analog to this is drag …
