Rites of Spring concert flier, Food For Thought, Washington, D.C. - December 15, 1984
No full textPhotocopy of an advertising flier promoting a concert by the Washington, D.C. punk band, Rites Of Spring. The concert occurred on December 15, 1984 at Food For Thought, a restaurant/concert venue in Washington, D.C. The other bands on the bill were the Washington, D.C. punk bands Gray Matter and Grand Mal. The photocopy was made by D.C. artist, author, and musician Sharon Cheslow as part of the research for "Banned in D.C.," a book she co-authored with Cynthia Connolly and Leslie Clague
State of Alert (S.O.A.), Untouchables, Minor Threat, Type-O concert flier, Washington, D.C., December 17-18, 1980
No full textFlier advertising State of Alert (S.O.A) concert at d.c. space, with Untouchables, Minor Threat, Type-O, Nurses, Fluffy Pig, and Wiggly Mittens, Washington, D.C., December 17-18, 1980. These concerts were also known as the Unheard Music festival. Within a year, S.O.A. vocalist Henry Garfield joined the influential California hardcore punk Black Flag and changed his last name to Rollins. He went on to a successful career as a musician, author, actor, television host and more. Guitarist Michael Hampton went on to play in the notable D.C. bands The Faith, Embrace, The Snakes, and Manifesto. These concerts were some of the first performances by Minor Threat. Fronted by vocalist Ian MacKaye (who went on to play in the bands Fugazi, Embrace, and The Evens), Minor Threat went on to become the definitive D.C. hardcore punk band

Flood defenses Washington D.C.
No full textThe United States of America have a safety standard for flood protection of 1/100 year. However the flood protections in the Washington D.C. do not comply with this requirement. During this study the levees in Washington D.C. area were analysed and it was found, that in order to comply with the 1/100 safety standard the levees in the NationalMall needs to be heighten by 0.5mand those near the Anacostia river by 1.5m. The safety standard of 1/100 imposed in the United States of America is not based on exact calculation, therefore another design method was applied, which uses an optimal safety level based on the damage cost of floods and investment cost of flood protections.The calculation of the optimal return period was based on the ’Standaardmethode 2017’ and it was found that the optimal return period at the NationalMall levee is 1/263 years. At the southern bank of the Anacostia river this optimal return period is 1/373 year. With these return periods new levees were designed in order to ensure the safety of the area of Washington D.C. There were two new levees needed around the National mall. The first was situated north of the Lincolnmemory along the Potomac river and the second replaces the temporary flood defence by the 2nd street SW and had an L-shape facing the Potomac river. The Anacostia levee was stretched on the East side in order to comply with the new 1/373 year safety standard. The old and new National mall levees needed a height of 3.5 m and those by the Anacostia needed a height of 8.5 m. It is important to take cautionwith these new levees as some houses needed to be removed. An attempt was made at modelling the above mentioned floods in ADCIRC to improve the accuracy of the design water levels and to verify the final design. However, the model showed instabilities, preventing the results from being used.Explanations for these instabilities are the incoming water not being properly ramped up, the large vertical gradients in shallow areas and the upstream and downstream boundaries being too close to each other.MP278Multidisciplinary Projec
El carácter defensivo de Xochicalco (650-1100 d.C.). 43. Arqueología
No full textA partir del debilitamiento teotihuacano, alrededor del año 650 d.C., surgen varios sitios con características defensivas en toda Mesoamérica. Se ha considerado a Xochicalco como una ciudad de orden defensivo y militar, desde la primera vez que se visitó en 1777, dada la presencia de murallas, bastiones y fosos. Investigaciones recientes —aunadas a trabajos anteriores en una de las entradas principales a Xochicalco— ratifican que entre los años 650 y 1100 d.C., estos elementos arquitectónicos tuvieron una función defensiva, a pesar de que involucran diferentes áreas de actividad, incluyendo las de tipo ritual. La ciudad tenía todo previsto para efectuar la defensa ante un asalto, un ataque frontal o por los costados, la invasión, la escalada, el confinamiento, todo menos un conflicto interno que le llevaría a su total abandono

Effect of Lossy Networks on Stereoscopic 3D-Video Streams
Full text linkWe present an experimental study of the sensitivity of stereoscopic 3D-Video streams to lossy networks. By means of a controlled network testbed, we impaired and assessed the quality of a broad range of 3D stereoscopic video sequences considering different content types, compression levels and packet loss rates. Our study and methodology are meant to provide service providers with the means to pinpoint the working boundaries of their videosets in face of different network conditions
Network Performance Assessment with Quality of Experience Benchmarks
Full text linkToday the performance of network services and devices is mainly assessed using Quality of Services (QoS) factors. These provide statistics about the quality of the network behavior but cannot accurately reflect how the unpredictable impairments which might occur in the network end up affecting the perception of the final beneficiary of these services, i.e. the user. This situation arises because QoS-based performance analysis does not capture the combined end-to-end properties of networks and applications. In this paper, we introduce a new network performance methodology based on Quality of Experience benchmarks, whereby we estimate the quality of the service as it is perceived by the user. We illustrate this approach in the context of video streaming services, showing how to evaluate quality degradation in Software Defined Networks. Our approach is better suited to the evaluation of dynamic networks and helps better pinpointing the critical factors that affect the applications the most
