Effects of Sports Drinks on the performance of Young Soccer Players
… soccer players, ages 10 and 11, performed two experimental trials while consuming 32 ounces of either a sports drink (G)- Gatorade or a placebo (P)- Crystal Light in a double-blind, crossover design. Both trials consisted of a 15-minute warm-up period, a pre and post exercise test protocol and …

Segregation of granular particles in suspension flow
… the development of the instabilities, and in experimental trials where stripes were not initially seen, the application of a shear stress was able to induce the fluid to develop the instability.

Tip-up and stabilization of an autonomous four-wheeled vehicle
… position. The controller was implemented on experimental hardware, which included an ARM7-based FEZ Domino microcontroller and a MicroStrain 3DM-GX2 inertial measurement unit. Data logged during experimental trials were analyzed in MATLAB to assess the stability and effectiveness of the …

Composite circular braid mechanics
… underlying the model's formulation, a series of experimental trials are documented that verify the fundamental braid mechanics. A wide variety of analytical cases are also introduced to investigate the influences of various model parameters. Possible extensions for the existing model are also …

Biometric and Biomechanical Sensing for Violin Performance Analysis
… of a violinist’s performance. Results from experimental trials reveal that the EVPS system provides relatively reliable data on expressive violin performance. While the general measures of physicality did not reveal significant differences between players of distinct skill levels, …

Advanced controllers for building energy management systems. Advanced controllers based on traditional mathematical methods (MIMO P+I, state-space, adaptive solutions with constraints) and intelligent solutions (fuzzy logic and genetic algorithms) are investigated for humidifying, ventilating and air-conditioning applications.
… designed control solutions are verified through experimental trials using the full-scale BMS facility at the University of Bradford.

Autonomous active ankle exo-skeleton devices provide metabolic cost reduction
… and pulse were recorded for both control and experimental trials. Using these physiological responses, associated energy expenditure rates were calculated. The results of these trials suggest the presence of a quantifiable reduction in energy expenditure rate seen by the implementation of an …

The effects of two breathing patterns on selected physiological parameters during a simulated 200 yard freestyle in male swimmers
… responses to a timed swim were made under two experimental breathing conditions. The intensity of the experimental trials was maintained at approximately 95% of the subjects' maximal workload to induce maximal effort. The validity of capillary blood samples for the use of micro-determination of …

Application of Optical CT to Estimate the Mass of Macroalgae in a Tank of Water
… the relationship was inconsistent across experimental trials, and the reconstructed volumes were blurry and inaccurate. Despite several tests and analyses, these difficulties remain unexplained at this time. While the system has some potential due to the strong linearity within sets, the …

Use of a Two-Action Paradigm Apparatus with Captive Lemurs: Insights into Social Learning
… to pull), and control (no model). I conducted experimental trials to determine if lemurs in push/pull groups learned faster and more efficiently from the model than lemurs in control groups who lacked a model to observe. I found evidence of social facilitation in that lemurs in control groups …

Enabling Long-Range Underwater Backscatter via Van Atta Acoustic Networks
… and evaluated it in over 1,500 real-world experimental trials in a river and the ocean. Our evaluation demonstrates that VAB achieves a communication range that exceeds 300m in round trip backscatter across orientations (at BER of 10-3). We compared our design head-to-head with past …
