Micro free-flow isoelectric focusing
… complexity and increase assay sensitivity. Rapid free flow isoelectric focusing (FF-IEF) is achieved in a microfluidic device by isolating the electrodes from the focusing region with porous buffer regions. Moving the electrodes enables the use of large electric fields without the detrimental …

Enhancing Micro Free Flow Electrophoresis: Detection, Application, And Fabrication
Micro Free Flow Electrophoresis (µFFE) is a separation technique where analytes are moved through a planar separation channel via pressure driven flow. Analytes streams are deflected laterally within an electric field applied perpendicular to the flow and separated from one another based on …

Analytik und präparative Trennungen liposomaler Systeme mit Zonen-Free-Flow Elektrophorese
… herauszufinden, inwieweit sich die Methode der Free-Flow Elektrophorese (FFE) dazu eignet, liposomale Systeme aufzutrennen. <br>Zwischen einzelnen Liposomen findet ein Lipidaustausch statt, d.h. Lipide wechseln ihren Aufenthaltsort zwischen zwei benachbarten Liposomen. Die FFE ermöglicht auf …

A Study of Inclement Weather Impacts on Freeway Free-Flow Speed
… duration on the accuracy of loop detector speed, flow, and density measurements using a Monte Carlo simulation approach. The inputs to the model are the frequency of failures and failure duration. Several regression models were developed to relate loop detector accuracy to detector failure data. …

Estimating the Effect of Connected and Autonomous vehicles (CAVs) on Capacity and Level of Service at Freeway Merge Segments
… methodology in obtaining Level of Service for freeways when Connected and Autonomous Vehicles (CAVs) are present inside the traffic stream. Accordingly, various two-lane heterogeneous flow scenarios were modelled which included variations in free-flow speed and percent of heavy vehicles wherein …

Performance-directed design of asynchronous VLSI systems / Samuel Scott Appleton.
… new method for describing asynchronous systems (free-flow asynchronism). The method is demonstrated through two applications ; a channel signalling system and amedo.

Modeling drivers' acceleration and lane changing behavior
… model defines two regimes of traffic flow: the car-following regime and the free-flow regime. In the car-following regime, a driver is assumed to follow his/her leader, while in the free-flow regime, a driver is assumed to try to attain his/her desired speed. A probabilistic model, …

Secrecy in Political Communication: Aspects of an Analytical Framework
Concerns about First Amendment rights and the free press have inspired numerous accounts and studies of political secrecy, usually to reassert the importance of the free flow of information in a democratic society or to detect indicators of deception. Such studies frequently assume that secrec

Legal regulations of the capital market in Nigeria : analysis and prospects for reform
… The execution of these projects requires the free-flow of capital. The capital market serves various purposes to a country, principal amongst these is that it facilitates the free-flow of short and long term equity and debt capital to corporations and governments that use it to carry out …

The History of Chinese Cybersecurity: Current Effects on Chinese Society Economy, and Foreign Relations
… all suggest that there is a free flow of Internet both within and without China that promotes peaceful socioeconomic development which the Chinese government seeks to promote.<em> </em>But is China sacrificing lucrative business prospects to secure their country? From whom is …

Data-Fitted Generic Second Order Macroscopic Traffic Flow Models
… (PW) model. The ARZ model possesses a family of flow rate versus density (FD) curves, rather than a single one as in the ``first order" Lighthill-Whitham-Richards (LWR) model. This is more realistic especially during congested traffic state, where the historic fundamental diagram data points are …

Safety Evaluation of Freeway Exit Ramps
… exit ramp types on safety performance for freeway diverge areas; and (2) to identify the different factors contributing to the crashes happening on the exit ramp sections. To achieve the research objectives, the research team investigated crash history at 424 sites throughout Florida. The …

Underfill material selection for flip chip technology
… each underfill material. A material with a fast flow rate, uniform and void free flow pattern, fast curing schedule, good thermal and mechanical properties, and good reliability results is needed to satisfy the requirements for this project. Materials F and E exhibited all the above requirements …

Development of a User Cost Estimation Procedure for Work Zones.
… sooner, thus allowing traffic to return to the free-flow speed. Methods to determine user costs are explored through a literature search, questionnaire survey, and interviews with employees of the Utah Department of Transportation (UDOT). Based on the research and interviews, a program named …

Experimental investigation on turbulent flow overlying permeable walls
A turbulent flow overlying a permeable wall can be subdivided into two distinct flow regions separated by a permeable interface. The first is the surface (or free) flow region, which overlies the interface. The second is the subsurface (or pore) flow region, which occurs within the permeable wall. …

Recovery Strategies and Flow Modeling in Fractured Grosmont Carbonates with High Permeability Conduits
… its possibility to describe the multi-physical flow in both free flow fractures and porous matrix. The application range and validity of Brinkman-Stokes multi-physical flow on karstified carbonates are discussed.

A Framework for Dynamic Traffic Monitoring Using Vehicular Ad-Hoc Networks
… various traffic conditions (<em>e.g.</em>, free flow traffic, transient flow traffic, traffic with congestion, etc.). We show that DTMon can accurately monitor speed and travel times in both free-flow and traffic with transient congestion. For some types of data, the percentage of equipped …

Incidentalità in ambito urbano: studio del comportamento di guida in relazione alle caratteristiche geometriche dell’infrastruttura stradale
… in two scenarios: normal traffic and under free flow conditions when vehicles are isolated. Particular attention was given to define the isolated vehicle. In the literature the definition of isolated vehicle does not exist for urban roads. For this reason, the time intervals were defined. …
