We introduce online codes – a class of near-optimal codes for a very general loss channel which we call the free channel. Online codes are linear encoding/decoding time codes, based on sparse bipartite graphs, similar to Tornado codes, with a couple of novel properties: local encodability and rateless-ness. Local encodability is the property that each block of the encoding of a message can be c...

AbstracrMirror sites enable client requests to be serviced by any of a number of servers, reducing load at individual servers and dispersing network load. Typically, a client requests service from a single mirror site. We consider enabling a client to access a file from multiple mirror sites in parallel to speed up the download. To eliminate complex client-server negotiations that a straightfor...

A 116 infectious disease Rare fungal illness follows tornado More than 1,000 people were injured when a severe tornado ripped through Joplin, Missouri, on 22 May 2011, and 158 eventually died. 1 Within a few days of the tornado, several of the injured began to suffer from a fungal infection suspected to be cutaneous necrotizing mucormycosis. Doctors scrambled to do what they could, but testing ...

This paper aims to offer an accessible, flexible, and homogenised approach career counselling development via the conceptualisation of a new metaphor in response evolving careers labour markets. The research question asks: How can Weather as Career Metaphor (WCM) accessible tool for counsellors use with their clients across lifespans? theoretical framework draws together sustainable theory cons...

The analytical model for tornado vortices is crucial in both the wind field characterization and tornado-resistant design of civil structures. objective this study to derive a novel three-dimensional from vortex governing equations simplified based on force balance analysis tornado-like (TLVs). First, TLVs with different swirl ratios are generated numerical simulator utilizing large-eddy simula...

A significant tornado passed through the Oklahoma City metropolitan area on May 3,1999. This study was undertaken at St Michael Hospital (Oklahoma City, Okla) to describe the impact on a community hospital's emergency department close to the tornado strike zone. Cases were defined as patients receiving diagnostic procedures, care, and interventions at the study hospital's emergency department f...

BACKGROUND Implementation of clinical guidelines for diagnosis and treatment of attention deficit hyperactivity disorder (ADHD) in children and adolescents is a challenge in practice due to insufficient availability of mental health specialists and lack of effective cooperation with primary care physicians. The Tornado program aims to reduce time between referral and start of treatment in eligi...

An experimental study was conducted to quantify the characteristics of wake vortex and flow structures around a gable-Roof building model as well as the resultant pressure distribution and wind loads (both forces and moments) acting on the test model in tornadolike winds. In addition to measuring the pressure acting on the tested high-rise building model using pressure transducers and wind load...

A Doppler radar emulator was developed to simulate the expected mean returns from scanning radar, including pulse-to-pulse variability associated with changes in viewing angle and atmospheric structure. Based on the user’s configuration, the emulator samples the numerical simulation output to produce simulated returned power, equivalent radar reflectivity, Doppler velocity, and Doppler spectrum...

In this paper we analyze the behavior of tornado time-series in the U.S. from the perspective of dynamical systems. A tornado is a violently rotating column of air extending from a cumulonimbus cloud down to the ground. Such phenomena reveal features that are well described by power law functions and unveil characteristics found in systems with long range memory effects. Tornado time series are...
