Cross border banking supervision : incentive conflicts in supervisory information sharing between home and host supervisors

The global financial crisis has uncovered a number of weaknesses in the supervision and regulation of cross border banks. One such weakness was the lack of effective cooperation among banking supervisors. Since then, international bodies, such as the G-20, the Financial Stability Board and the Basel Committee have actively promoted the use of supervisory colleges. The objective of this paper is to explore the obstacles to effective cross border supervisory information sharing. More specifically, a schematic presentation illustrating the misalignments in incentives for information sharing between home and host supervisors under the current supervisory task-sharing anchored in the Basel Concordat is developed. This paper finds that in the absence of an ex ante agreed upon resolution and burden-sharing mechanism and deteriorating health of the bank, incentive conflicts escalate and supervisory cooperation breaks down. The promotion of good practices for cooperation in supervisory colleges is thus not sufficient to address the existing incentive conflicts. What is needed is a rigorous analysis and review of the supervisory task-sharing framework, so that the right incentives are secured during all stages of the supervisory process. For this purpose, it is essential that policy makers integrate and harmonize the current debates on crisis management, resolution policy and good supervisory practices for cross border banking supervision.Banks&Banking Reform,Emerging Markets,Labor Policies,Financial Intermediation,Debt Markets

Advanced nonlinear modelling techniques for switched reluctance machines

This paper gives an overview of different modelling techniques to describe the nonlinear behaviour of both saturated switched reluctance machine (SRM) and power electronic converter. The current research contributes by comparing the de-coupled single-phase superposition method (lookup-tables) with a coupled analysis between drive model in Matlab/Simulink® and finite element model of the SRM motor. Experimental characterization techniques as well as finite element techniques are used to obtain the single-phase flux-linkage data. Transient electromagnetic analysis using the finite element method,coupled with a drive model and optimization strategy in Matlab/Simulink®, results in a more accurate SRM modelling. These results are more accurate because the mutual coupling between different phases is taken into account. Using this direct coupling, a complete analysis of the motor behaviour (local saturation, iron losses, …) can be modelled with the finite element software, keeping the complex drive and control strategy in Matlab/Simulink®.At every time step of the discrete solver, data is exchanged between the drive model and the coupled electric circuit of the finite element analysis.Simulation results are compared with measurements offlux-linkage, torque, phase current and iron losses. Pro’s and contra’s of the coupled and de-coupled modelling technique are discussed

Modeling of the behavior of AC undervoltage relays during voltage dips

This paper proposes a dynamic model for the behavior of an AC undervoltage protection relay during voltage dips. The behavior is expressed by means of standardized voltage tolerance curves and highly depends on the point on-wave (phase angle) of the dip initiation. Using the model, it can be explained that AC undervoltage relays are much more sensitive to voltage dips of e.g. 50% Urated than to short interruptions (0% Urated), caused by the magnetic behavior. The model takes into account the electrical, magnetic and mechanical system equations. An experimental set-up with a programmable power source as dipgenerator is build to validate the model. Finally, a complete weaving machine is represented to analyze the influence towards voltage dip immunity by adding an undervoltage protection relay

Egypt and Syria in the Fatimid, Ayyubid and Mamluk Eras - IX

This is the ninth volume of CHESFAME’s proceedings, with contributions from the twenty-third and twenty-fourth meetings of CHESFAME, which were held at the University of Leuven (KU Leuven, Belgium) in May 2015 and 2016. This collected volume of fifteen contributions once again reflect the uniquely wide range of the research and debates that —as also stated in the prefaces of previous proceedings— have always constituted CHESFAME’S core business, ever since its first meeting in 1992. As always, many of these contributions again have little more in common than their geographical, chronological and historiographical links with the Islamic eastern Mediterranean world between the tenth and the fifteenth centuries CE. As always, also, these contributions represent in their diversity the crux of CHESFAME’s remit, the key to its success over many years and the unique essence of its scholarly identity: its organisational set-up around principles of multi-disciplinarity and of trans-cultural and trans-dynastic cross-fertilization, long before these became fashionable buzz-words in Western higher education and academia. In line with the tradition of CHESFAME meetings and proceedings, this ninth collected volume is once again divided in three dynastic sections (each arranged alphabetically by the authors’ surnames): first a condensed Fatimid section (1 chapter), and then two well represented sections on Zengid and Ayyubid times (6 chapters) and on the so-called Mamluk era (8 chapters). The Fatimid section represents in integrated approach to the rich intersection of literary narrative and material culture (Richter-Bernburg). The Zengid and Ayyubid section furthers this (Ducène, Nicolle, Piana), but also opens up towards the engagements with the history of ideas, of discourse, and of mentalities more in general (Antrim, Goudi, Zouihal). The Mamluk section finally similarly combines discussion of material culture (Abdel Barr) and literature (Lelli, Martel-Thoumian) with the history of ideas (Post) as well as with engagements with the highly diverse social worlds from East and West that connected in often surprising ways with the sultanate and its many agents (Claverie, Coureas, Wijntjes)

A practical approach to the influence of ground connection on inverter supplied electrical machines

It is known that the steep voltage changes caused byIGBT frequency inverters can cause overvoltage problems at motor terminals and in the motor winding [1,2,3]. Moreover,due to the distributed phase capacitances of the cable, these voltage changes cause a voltage variation in the ground wire[4], which can only be partially eliminated by introducing filters that limit the rate of change of the voltage [5]. This paper investigates, through a number of test measurements,the influence of cable type and cable length on the induced ground wire voltage for most practically applied combinations of ground connections
