This document describes an efficient method for exporting bidirectional flow (Biflow) information using the IP Flow Information Export (IPFIX) protocol, representing each Biflow using a single Flow Record.

This paper presents new, efficient methods for computing finite-time Lyapunov exponent (FTLE) fields in unsteady flows. The methods approximate the particle flow map to eliminate redundant particle integrations in neighboring flow map calculations. Two classes of flow map approximations are investigated based on composition of intermediate flow maps; unidirectional approximation constructs a ti...

Machine comprehension (MC), answering a query about a given context paragraph, requires modeling complex interactions between the context and the query. Recently, attention mechanisms have been successfully extended to MC. Typically these methods use attention to focus on a small portion of the context and summarize it with a fixed-size vector, couple attentions temporally, and/or often form a ...

Conventional thermal flow sensors require samples to be heated; however, the temperature rise of measuring tools limits their use in biological applications. To address this limitation, study, we propose a sensor with bidirectional reference. We fabricated an integrated calorimetric and hot-film reference using Peltier module produce distribution that depends on rate. The enable high-resolution...

Bidirectional data flow analysis has become the standard technique for solving bit-vector based code motion problems in the presence of critical edges. Unfortunately, bidirectional analyses have turned out to be conceptually and computationally harder than their unidirectional counterparts. In this paper we show that code motion in the presence of critical edges can be achieved without bidirect...

Power electronic converter systems for applications such as telecom, automotive, and space can have dc voltage buses that are backed up with batteries or super-capacitors. These batteries or super-capacitors are connected to the buses with bidirectional dc–dc converters which allow them to discharged or charged, depending on the operating conditions. Bidirectional dc–dc converters may be isolat...

In 26 of 214 patients with erectile dysfunction and proved venous incompetence by cavernosography, an additional bidirectional Doppler ultrasound was performed also to demonstrate venous outflow disturbances. All except one leakage in the superficial and deep dorsal veins could be demonstrated as well as 4 of 6 cavernosum-glandular shunts. Bidirectional Doppler ultrasound visualized a continuou...
