Conducted analyse of the knowledge of design brick arched lintels shows lack of information about the mentioned process. The only piece of information, reached by the author, includes simplified matching method of arch’s shape by empirical use of ultimate limit state method. Presented paper contains review of more interesting empirical and numeric research. Additionally, the analyse of technica...

This paper introduces Europe’s largest Canal Bridge found in Magdeburg, Germany. The uncommon nature of the bridge is established through its history and its function. Various relative checks are then applied on critical aspects under its Ultimate Limit State. A structural analysis of critical members, according to BS5400, is also undertaken.

We examine the ultimate fate of individual opinions in a socially interacting population of leftists, centrists and rightists. In an elemental interaction between agents, a centrist and a leftist can both become centrists or both become leftists with equal rates (and similarly for a centrist and a rightist). However leftists and rightists do not interact. This interaction step between pairs of ...

The measurement of relative displacements and deformations is important in many fields such as structural engineering, aerospace, geophysics, and nanotechnology. Optical-fiber sensors have become key tools for strain measurements, with sensitivity limits ranging between 10(-9) and 10(-6)ε hertz (Hz)(-1/2) (where ε is the fractional length change). We report on strain measurements at the 10(-13)...

We recall the motivation for research in high-gradient acceleration and the problems posed by a compact collider. We summarize the phenomena known to appear in operation of a solid-state structure with large fields, and research relevant to the question of the ultimate gradient. We take note of new concepts, and examine one in detail, a miniature particle accelerator based on an active millimet...

The present paper investigates the effect of limit state selection ~strength versus serviceability! on bridge deck life-cycle costs and thus on optimal repair strategies. Such a comparison may then help determine whether safety or functionality ~or both! are important criteria when optimizing bridge life-cycle performance and costs. The structural element under consideration is a reinforced con...
