Abstract

Purpose

The modeling of magnetostrictive effects is a topic of intensive research. The authors' goal is the precise modeling and numerical simulation of the magnetic field and resulting mechanical vibrations caused by magnetostriction along the joint regions of electric transformers.

Design/methodology/approach

The authors apply the finite element (FE) method to efficiently solve the arising coupled system of partial differential equations describing magnetostriction. Hereby, they fully take the anisotropic behavior of the material into account, both in the computation of the nonlinear electromagnetic field as well as the induced magnetostrictive strains. To support their material models, the authors measure the magnetic as well as the mechanical hysteresis curves of the grain-oriented electrical steel sheets with different orientations (w.r.t the rolling direction). From these curves they then extract for each orientation the corresponding commutation curve, so that the hysteretic behavior is simplified to a nonlinear one.

Findings

The numerical simulations show strong differences both in the magnetic field as well as mechanical vibrations when comparing this newly developed anisotropic model to an isotropic one, which just uses measured curves in rolling direction of the steel sheets. Therefore, a realistic modeling of the magnetostrictive behavior, especially for grain-oriented electrical steel as used in transformers, needs to take into account the anisotropic material behavior.

Originality/value

The authors have developed an enhanced material model for describing magnetostrictive effects along the joint regions of electric transformers, which fully considers the anisotropic material behavior. This model has been integrated into a FE scheme to numerically simulate the mechanical vibrations in transformer cores caused by magnetostriction.

Abstract

Map of this detour: This is one of a series of detours compelled by consideration of inheritance law as an aspect of cultural transmission. 1 This course draws attention to three problematic time forms (temporalities) through which the “self” and its relations with history are often written and read. These implicit time forms are all too common and all too easily go unrecognized. Each involves the illusion of some kind of exalted and immediate convergence between the self (the subject) and an object of exaggerated importance to this self (the world, the universe, the metaphysical or artistic beyond, the origin, etc.). Three figures are explored here: that of Hercules in Hegel’s Aesthetics, and those of Adrian and Breisacher in Thomas Mann’s Doctor Faustus. Each of these invites attention to a different temporality through which an exalted convergence may be imagined: the first involves a fantasy of immediate belonging to the whole of history, the second, that of escape forward from history (toward a self-created “ultimate” object), and the third, that of return to fullness in origin (before history). This detour also suggests ways of reading history (including “reading for mana through glances,” which will be explained) that protect against the problems just described. The detour closes considering implications of all of the above for U.S. inheritance law. The tutor text for this last leg is François Mauriac’s Le noeud de vipères.

Abstract

Purpose

This paper aims to investigate how digital capabilities associated with building information modelling (BIM) can integrate a wide range of information to improve built asset management (BAM) decision-making during the in-use phase of hospital buildings.

Design/methodology/approach

A comprehensive document analysis and a participatory case study was undertaken with a regional NHS hospital to review the type of information that can be used to better inform BAM decision-making to develop a conceptual framework to improve information use during the health-care BAM process, test how the conceptual framework can be applied within a BAM division of a health-care organisation and develop a cloud-based BIM application.

Findings

BIM has the potential to facilitate better informed BAM decision-making by integrating a wide range of information related to the physical condition of built assets, resources available for BAM and the built asset’s contribution to health-care provision within an organisation. However, interdepartmental information sharing requires a significant level of time and cost investment and changes to information gathering and storing practices within the whole organisation.

Originality/value

This research demonstrated that the implementation of BIM during the in-use phase of hospital buildings is different to that in the design and construction phases. At the in-use phase, BIM needs to integrate and communicate information within and between the estates, facilities division and other departments of the organisation. This poses a significant change management task for the organisation’s information management systems. Thus, a strategically driven top-down organisational approach is needed to implement BIM for the in-use phase of hospital buildings.

Abstract

Purpose

The financial crisis 2007‐2009 calls for a regulatory response. A crucial element of this task is the treatment of systemic risk. Basel III gains centre stage in this process. Thus, the purpose of this paper is to evaluate Basel III, examining its ability to reduce systemic risk.

Design/methodology/approach

The paper highlights the importance of reducing systemic risk to achieve the goal of overall financial stability. By first focusing on the theoretical foundations of systemic risk, this paper explores and analyzes the crucial aspects of this almost impalpable risk type. It further investigates the current regulation of systemic risk, clearly showing Basel II's inability to reduce it. Then, it evaluates the Basel Committee's efforts to address these weaknesses through Basel III by investigating its incentives and its ability to reduce obvious drawbacks of Basel II as well as systemic risk factors.

Findings

The findings show that there are still adjustments necessary. Although the development of Basel III is well advanced, providing some stabilizing incentives, there are still issues calling for closer consideration to counter all Basel II drawbacks and systemic risk factors adequately. These include: a risk‐weighted leverage ratio; a more thorough treatment of procyclicality; adjustments for the NSFR (Net Stable Funding ratio); and most importantly, the mandatory issue to internalize negative externalities from financial institutions, that is, the call for pricing systemic risk.

Originality/value

The paper not only examines the new Basel III framework, as a response to the Financial Crisis 2007‐2009, but also draws attention to specific areas which the Basel Committee and regulators need to focus on more thoroughly.

Abstract

Includes four outstanding essays from the Scottish Schools Essay Competition, illustrating how children see libraries and bookshops, and improvements they would like to see made. Demonstrates not only good creative writing, but an awareness, on the part of the young, of what is currently available and what could become available for the library/bookshop user. Includes some criticism and some praise, particularly with regard to the modern library.

Abstract

In this chapter, we describe the rise and fall of Germany’s Neuer Markt from its promising start to its ultimate failure. We show that the Neuer Markt was designed to serve the special needs of small and medium sized growth firms. However, some regulatory flaws, insufficient means to enforce the rules, the IPO frenzy and the bursting of the stock market bubble destroyed its reputation beyond recovery. The closing of the Neuer Markt and the rebranding and restructuring of the entire Frankfurt stock market indicate the seriousness of the crisis of German public equity markets.
