Precision rotational rheometry
For rotational rheometers, alignment of rotating surfaces is of prime importance in conducting accurate, reproducible measurements. A custom glass bottom surface has been designed and fabricated that has < 1 µm of planar misalignment with respect to the instrument axis of rotation. This also …

Optimizing Weapon Precision
An accurate soldier is a lethal soldier, lethal soldiers make an effective army, and an effective army is a deterrent to war. In this paper we aim to apply optimization methods to nonlinear trajectory models to make every soldier more lethal with their assigned weapon system (and hunters more …

Precision Cosmological Parameter Estimation
Our idea is to shift the computationally intensive pieces of the parameter estimation framework to a parallel training step. We then provide a machine learning code that uses this training set to learn the relationship between the underlying cosmological parameters and the function we wish to …

Precision connector assembly automation
Telecommunication systems, network servers, mainframes, and high-performance computers contain several printed circuit boards (PCBs) that are mounted in card-cage assemblies. Level-3 connectors, often called board-to-board connectors, transmit signals between the primary backplane PCB and the …

Precision hybrid pipelined ADC
… explore the use of the ZCBC technique for high-precision ADCs. The goal of the project is a 13-bit pipelined ADC operating at up to 100MS/s. A two-phase hybrid ZCBC operation is used to improve the power-linearity tradeoff of the A/D conversion. The first phase approximates the final output …

Precision Aggregated Local Models
… continuity, as a flagship example of what I call precision aggregated local models (PALM). Using N_C LAGPs, each selecting n from N data pairs, I illustrate a scheme that is at most cubic in n, quadratic in N_C, and linear in N, drastically reducing computational and storage demands. Extensive …
