Finite element prediction of the ultimate axial load capacity of V-section band clamps
Band clamps with a flat bottomed V-section are used to connect a pair of circular flanges to provide a joint with significant axial strength. Despite the wide application of Vband clamps, their behaviour is not fully understood and the ultimate axial strength is currently only available from physical testing. This physical testing has indicated that the ultimate strength is determined by two different types of structural deformation, an elastic deformation
mode and a plastic deformation mode. Initial finite element analysis work has demonstrated
that analysis of this class of problem is not straightforward. This paper discusses the difficulties encountered when simulating this type of component interaction where contact is highly localised and contact pressures are high
Muller v Oregon: Reassessing Protective Legislation
Although the Progressive Era has drawn the attention of countless scholars, few historians have deeply investigated one of the most important Supreme Court cases of the era, Muller v. Oregon (1908). It was not until the failure of the Equal Rights Amendment (ERA) in 1972 that scholars seriously considered the case. The failure of the ERA brought a surge of scholarship from the field of history, law, sociology, psychology, and communications. This historiography examines the reemergence of interest in Muller v. Oregon in the years following the ERA’s failure. In addition to examining the increasing interest of scholars, this historiography also considers the method in which secondary school educators should teach the Muller case. Should Muller be taught as a triumph of progressivism or as a setback for women’s rights? This historiography considers the important changes Muller brought to the Supreme Court’s decision-making process as well as the damaging legacy left in its wake. As the United States appears to move toward revoking protective legislation for a woman’s reproductive rights, Muller v. Oregon, deserves to be studied by students and scholars alike
Indicator functions, v-numbers and Gorenstein rings in the theory of projective Reed-Muller-type codes
For projective Reed--Muller-type codes we give a global duality criterion in
terms of the v-number and the Hilbert function of a vanishing ideal. As an
application, we provide a global duality theorem for projective
Reed--Muller-type codes over Gorenstein vanishing ideals, generalizing the
known case where the vanishing ideal is a complete intersection. We classify
self dual Reed-Muller-type codes over Gorenstein ideals using the regularity
and a parity check matrix. For projective evaluation codes, we give a duality
theorem inspired by that of affine evaluation codes. We show how to compute the
regularity index of the -th generalized Hamming weight function in terms of
the standard indicator functions of the set of evaluation points.Comment: 33 page

A Class by Herself: Muller v. Oregon (1908)
This chapter assesses Muller v. Oregon (1908), its significance, and the law it upheld: Oregon's ten-hour law of 1903. Convicted of violating Oregon's law of 1903 that barred the employment of women in factories and laundries for more than ten hours a day, Curt Muller—the owner of a Portland laundry—challenged the constitutionality of the law, which he claimed violated his right of freedom to contract under the due process of the Fourteenth Amendment. On February 24, 1908, the Supreme Court unanimously upheld the Oregon law. This decision marked a momentous triumph for progressive reformers and a turning point in the movement for protective laws. At the same time, by declaring woman “in a class by herself,” the Supreme Court embedded in constitutional law an axiom of female difference. The Muller decision thus pushed public policy forward toward modern labor standards and simultaneously distanced it from sexual equality.</p
Classical and numerical approaches to determining V-section band clamp axial stiffness
V-band clamp joints are used in a wide range of applications to connect circular flanges, for ducts, pipes and the turbocharger housing. Previous studies and research on V-bands are either purely empirical or analytical with limited applicability on the variety of V-band design and working conditions. In this paper models of the V-band are developed based on the classical theory of solid mechanics and the finite element method to study the behaviour of the V-bands under axial loading conditions. The good agreement between results from the developed FEA and the classical model support the suitability of the latter to model V-band joints with diameters greater than 110 mm under axial loading. The results from both models suggest that the axial stiffness for this V-band cross section reaches a peak value for V-bands with radius of approximately 150 mm across a wide range of coefficients of friction. Also, it is shown that the coefficient of friction and the wedge angle have a significant effect on the axial stiffness of V-bands

Xenophobia and social closure: A development of a model from Coleman
The study builds on the results of an article from James Coleman entitled 'Norm-Generating Structures'. In this article Coleman considers whether cooperative behavior establishes itself through evolution as the norm in a social group when group members encounter foreigners occasionally. Since people cooperate in closed social groups the question that Coleman asks is: in what ways cooperation with foreigners depends on the degree of social closure? In the article mentioned above Coleman is only able to outline the answer to this question. The goal of this contribution is to broaden Coleman's model and completely answer the question, whereby it will become clear that Coleman's results only represent a special case. In general the evolution of cooperation with foreigners is unpredictable, but a low level of xenophobia can be established through evolution under a broad range of circumstances
