Scalable, repeatable, and contention-free parallelization of traffic simulation
Tripod is a project funded by ARPA-E and partly carried on by the Intelligent Transportation Systems (ITS) Lab at MIT that aims to promote more energy efficient travel options by offering commuters incentives to make smart travel choices. These incentives depend on the current network state, and …

Repeatable and adjustable on-demand local anesthesia using externally-triggerable liposomes
Pain management would be greatly enhanced by a formulation that would provide local anesthesia at the time desired by patients, with the desired intensity and duration. Current treatment for many pain states - including localized pain - often involves systemic medications such as opioids that have …

Technique for Repeatable Hyperosmotic Blood-Brain Barrier Disruption in the Dog
… the blood-brain barrier. However a technique for repeatable BBBD in the canine has not been described. This study describes a repeatable technique for BBBD in the dog and evaluates the clinical and morphological effects of BBBD. Using fluoroscopic guidance, an arterial catheter was directed into …

Optimal Parameter Values for Accurate and Repeatable Nanoindentation of Human Trabecular Bone
… rate that can be used to obtain accurate and repeatable material properties from human femoral trabecular bone through experimentation and statistical analysis. All testing was conducted using a single nanoindenter on a single trabeculae, with the assumption that material properties within the …

Development of Open-Source Software for Repeatable Processing of Mechanical Test Data
… a software toolkit for automated processing and repeatable analysis of mechanical test data. The toolkit, named Paramaterial, was developed as a pip installable Python package, and is designed for use in Jupyter Notebooks. The usage of Jupyter Notebooks makes the steps that a user took in …

GENERATION, MECHANICAL AND STATISTICAL ANALYSIS, AND FEM SIMULATION OF FRACTURE OF REPEATABLE RANDOM ROUGH SURFACES
Natural weathering and wear of structural materials in service nearly always generate surface roughness, and follow the Central Limit Theorem prediction for surface topology. This study couples experimental and statistical theory, and FEM to extend knowledge of life of materials from initial …

Effects of Training and Experience on Repeatable and Reliable Assessment of Beef Cattle Body Condition Scores
In recent years, body condition scores (BCS) have been included in Expected Progeny differences (EPD) calculations for maintenance energy. This experiment was designed to identify the acuteness at which technicians of different skill levels can correctly quantify BCS in beef cattle. Thirteen …

Establishment of a repeatable test procedure for measuring adhesion strength of particulates in contact with surfaces
The firm adhesion of flavouring particles onto snack surfaces during coating processes is a major concern in the snack production industry. Detachment of flavouring powders from products during handling and production stages can lead to poor appearance and reduced taste of the product as well as …

An Investigation into Improving the Repeatability of Steady- State Measurements from Nonlinear Systems. Methods for measuring repeatable data from steady-state engine tests were evaluated. A comprehensive and novel approach to acquiring high quality steady-state emissions data was developed
The calibration of modern internal combustion engines requires ever improving measurement data quality such that they comply with increasingly stringent emissions legislation. This study establishes methodology and a software tool to improve the quality of steady-state emissions measurements from …

Further development of a non-invasive infra-red (IR) system in clinical assessment of knee laxity in healthy volunteers
… 30° & 45° intervals. Valgus measurements were repeatable (CR 3°) between 5° and 15° of flexion, varus measurements were repeatable at 5°. The AP test for laxity was less successful, with only the assessment at 15° falling with the predefined limit of 3mm. When this experimental protocol was …

Assessing the Use of Ultrasound to Quantify Spine Kinematics
… imaging method was considered robust and repeatable however the transverse method was less repeatable, with error potentially resulting from soft tissue creep. This thesis demonstrated that it is possible to measure multiplanar intervertebral motion via US and may help identify risky …

Does personality affect competition, social organization, and fitness? a study using a small social mammal, Octodon degus
… variation among individual behaviors that are repeatable across time and contexts. Recent research in behavioral ecology has revealed that animal personality influences ecological and evolutionary processes, and a growing number of studies demonstrate that personality can play a large role in …

Robust Repetitive Control and Its Application
… tracking servo control problem to reject both repeatable runout (RRO) and non-repeatable runout (NRRO) simultaneously. Simulation results show that the position error signal (PES) of a disk drive is reduced by three folds. The initial response of the TPRRC as well as most other repetitive …

Design of planar-flexure-based contacts for high-repeatability kinematic couplings
… Few devices exist that are capable of passive, repeatable nanoscale fixturing; this research facilitates the design of such devices by providing a more complete understanding of how flexural elements affect their performance. Improvements in coupling technology are expected to decrease …
