The Behavior of Wood Shear Walls Designed Using Diekmann\u27s Method and Subjected to Static In-Plane Loading
No full textA method of distributing static forces through wood shear walls, called Diekmann\u27s Method, was used to design nominal 8-foot high and 12-foot and 8-foot long shear walls with window size openings. The shear walls were built and load tested in the Haggerty Hall Structures Laboratory at Marquette University. Diekmann\u27s Method has two cases. Case 1 assumes sheathing provides resistance to shear forces, shear forces are uniformly distributed along the length of sheathing, shear wall rigidity is linearly proportional to length, and only framing provides bending resistance. An additional assumption for Case 2 is that inflection points occur in panels adjacent to an opening at the mid-height of the opening. Equations of statics are used to distribute an applied load through a wall. The resulting sheathing-edge forces are designed to be resisted by sheathing-edge nails. When Diekmann\u27s Method Case 2 was used in load tests of twelve 12-foot long walls, the ultimate load analysis showed the results obtained were not those expected. Additionally, the walls did not appear to deform in the assumed double curvature shape. On the other hand, the ultimate loads for eight of the nine walls with openings exceeded those for the three walls with no openings. All aspects of the testing program were evaluated and were the basis for testing twenty-one 8-foot long walls. The 8-foot walls utilized Case 1 and were evaluated using the design load. These load tests showed that undesigned headers contribute to shear wall stiffness, full height panels have the potential to resist fractions of a laterally applied load, and panels below openings resist shear forces. The method and load test data are useful to design and manufacture wood shear walls
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Pseudospectral discretization of nonlinear delay equations: new prospects for numerical bifurcation analysis
No full textWe apply the pseudospectral discretization approach to nonlinear delay models described by delay differential equations, renewal equations or systems of coupled renewal equations and delay differential equations. The aim is to derive ordinary differential equations and to investigate the stability and bifurcation of equilibria of the original model by available software packages for continuation and bifurcation for ordinary differential equations. Theoretical and numerical results confirm the effectiveness and the versatility of the approach, opening a new perspective for the bifurcation analysis of delay equations, in particular coupled renewal and delay differential equations
On Common Intervals with Errors
No full textChauve C, Diekmann Y, Heber S, Mixtacki J, Rahmann S, Stoye J. On Common Intervals with Errors. Forschungsberichte. Bielefeld: Technische Fakultät der Universität Bielefeld; 2006.The information that groups of genes co-occur in several genomes provides a basis for further comparative genomic analysis. The task of finding such constellations, mostly referred to as gene clusters, has led to various models of increasing generality. A central feature to enhance the biological relevance of their definition when applied to real genomic data is to allow for slight differences in the gene content within a cluster, thus not only considering groups of exact equality. We contribute a model defining gene clusters as common intervals with errors and discuss different representations and the corresponding problems resulting for the search procedure
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
