ROV Power Cable Ampacity in Areas with High Ambient Temperatures

M. Hartland1, I. Roberts1
1Seabed Geosolutions, Houston, TX, USA

Offshore operations, using Robotically Operated Vehicles (ROVs) in areas with high ambient temperatures require ampacity limitations to be established. Specifically, the risk of overheating ROV umbilicals and tethers when running at high power, due to multiple layers on winch drums is a ... Per saperne di più

Silicon Nitride Corrugated Membrane with High-Width-Aspect-Ratio for MEMS Microphones

Shubham1
1Knowles Electronics, Itasca, IL, USA

Micro-Electro-Mechanical Devices such as acoustics sensors, finger print sensors, tunable capacitors etc. are widely used in commercial applications. The pressure sensors use membranes which deflect upon applied pressure load. The most important aspect of any pressure sensor is its ... Per saperne di più

Modeling Thrombosis through Viscosity Variation in a Coupled CFD-Chemical Kinetics Simulation

C. Rice1, R. Larson1
1University of Michigan, Ann Arbor, MI, USA

Thrombosis is the formation of a thrombus or blood clot within a vessel to maintain the integrity of the circulatory system [1]. The process involves surface interactions, with coagulation leading to the formation of thrombin and a fibrin network, and platelet aggregation [2]. ... Per saperne di più

Emerging battery technologies are addressing applications of renewable and fossil fuel energy sources since they can store and release energy on demand. In recent years significant strides have been made in lithium battery technology. Lithium batteries are the primary sources of power in ... Per saperne di più

Bumblebee Aerodynamics

R. Thiagarajan1, A. Prasad1, T. Nidi1
1ATOA Scientific Technologies Pvt Ltd, Bengaluru, India

Nature inspired innovation powered many engineering innovation. For example, Bird inspired flight helped us to develop intercontinental flying long range aircraft with efficiency as comparable to transcontinental migratory birds. But, short range air travel, efficiency is much lower than ... Per saperne di più

Finite Element Analysis of a Bipolar-Electrochemistry Based Water Sensor

J. Castro1
1Colorado College, Colorado Springs, CO, USA

This work computationally characterizes a new bipolar electrochemical sensing scheme recently developed for inexpensive detection of heavy metals in water. The sensing scheme employs a two-step optical anodic strip voltammetry protocol that couples a closed bipolar electrochemical cell ... Per saperne di più
