Robust fault detection filter design for a class of linear systems with mixed time-varying delays and nonlinear perturbations

2009

In this note, the problem of robust fault detection filter (RFDF) design for a class of linear systems subjected to some nonlinear perturbations and mixed neutral and discrete time-varying delays is investigated based on an H ∞ performance condition. By introducing a descriptor technique, using Lyapunov-Krasovskii functional and a suitable change of variables, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities (LMIs) to synthesize the residual generation scheme. Based on Luenberger type observers, the explicit expression of the filters is derived for the fault such that both asymptotic stability and a prescribed level of disturbance att…

Income structure, profitability and risk in the European banking sector: The impact of the crisis

2017

This study sets out to analyse whether the effect of the income structure on the risk and profitability of European banks has changed as a result of the crisis and if it varies according to banks’ specialisation in a particular type of banking business. To do so, it estimates the income structure over the period 2002–2012 using data for a panel of European banks. The study also examines if there are differences between investment-oriented banks and banks specialising in financial intermediation in terms of the effect of income structure on risk and profitability. Our findings show that an increase in the share of non-interest income has a negative impact on profitability, although the effec…

Quantifying Structural Subsidy Values for Systemically Important Financial Institutions

2013

Abstract Claimants to Systemically Important Financial Institutions (SIFIs) would receive transfers when governments are forced into bailouts. Ex ante, this bailout expectation lowers SIFIs’ daily funding costs. The funding cost advantage reflects both the structural level of the government support and the time-varying market valuation for such a support. Based on a large worldwide sample of banks, we estimate the value of the structural subsidy, by exploiting expectations of state support embedded in credit ratings and by applying the long-run average value of the rating bonus. The value of the structural subsidy was already sizable, 60 basis points (bp), as of the end-2007, before the cri…

Finansinis stabilumas ir koncentracija: besivystančios Europos tyrimas

2016

Šiame straipsnyje tiriamas bankų sektoriaus koncentracijos poveikis finansiniam stabilumui naudojant 134 komercinių bankų iš 17 Vidurio ir Rytų Europos šalių 2007-2012 m. laikotarpio duomenis. Empirinio tyrimo rezultatai pabrėžia vadinamąją „koncentracijos trapumo“ hipotezę, parodydami, kad aukštas koncentracijos lygis bankų sektoriuje yra siejamas su didesne bankų, ypač mažesniųjų, įsipareigojimų neįvykdymo tikimybe. Taip pat parodoma, kad neigiamas koncentracijos poveikis gali būti sumažintas taikant griežtą priežiūros sistemą. Pirmiausia - griežtas oficialus bankų sektoriaus priežiūros įgaliojimas. Antra - skirtingi priimančiosios šalies ir buveinės šalies priežiūros įgaliojimai gali žym…

New Tendencies of Management and Control of Operational Risk in Financial Institutions

2013

Abstract Nowadays, financial institutions highly recognize a great influence of effective risk management on profit abilities. Therefore risk management became an important part of the financial instrument. According to the latest researches, there still remain problems related to the management of various types of risks. For instance, the Basel Committee of the Bank of International Settlements imposes financial institutions for more intensive devoting their attention to operational risk management problems. Due to the increased intensity of performed financial operations, financial institutions became very vulnerable to operational risks. In many cases, the high level of operational risks…

A Chronology of Financial Crises for Norway

2010

The paper offers a chronology of financial crises in Norway from her independence in 1814 till present times. Firstly, business cycles, covering almost two hundred years of economic history are mapped. These reveal years of crises in the real economy. These seem to coincide with most of the major financial crises. Secondly, the paper the financial crises are described chronologically. Thirdly, the paper investigates key patterns in credit and money volumes. It concludes that major financial crises typically took place after substantial money and credit expansion causing financial instability, loss of long term equilibriums, overheating and bubbles followed by severe meltdowns in the economy.

Financial Sector Reform After the Crisis: Has Anything Happened?

2013

We analyze the reactions of stock returns and CDS spreads of banks from Europe and the United States to four major regulatory reforms in the aftermath of the subprime crisis, employing an event study analysis. In contrast to the public perception that nothing has happened, we find that financial markets indeed reacted to the structural reforms enacted at the national level. All reforms succeeded in reducing bail-out expectations, especially for systemic banks. However, banks' profitability was also affected, showing up in lower equity returns. The strongest effects were found for the Dodd-Frank Act (especially the Volcker rule), whereas market reactions to the German restructuring law were …

German Bank Lending During Emerging Market Crises: A Bank Level Analysis

2007

This paper studies German bank lending during the Asian and Russian crises, using a bank level data set, which has been compiled from credit data at the Deutsche Bundesbank. Our aim is to gain more insight into the pattern of German bank lending during financial crises in emerging markets. We find that German banks reacted to the Asian crisis mainly by reallocating their portfolios among emerging markets. This behaviour is consistent with active portfolio management and does not necessarily indicate a spontaneous reaction to the Asian crisis. By contrast, the banks' behaviour during the Russian crisis is characterised by a general withdrawal from emerging markets. The use of micro data allo…

Modeling the electromechanical impedance technique for the assessment of dental implant stability

2015

We simulated the electromechanical impedance (EMI) technique to assess the stability of dental implants. The technique consists of bonding a piezoelectric transducer to the element to be monitored. When subjected to an electric field, the transducer induces structural excitations which, in turn, affect the transducer's electrical admittance. As the structural vibrations depend on the mechanical impedance of the element, the measurement of the transducer's admittance can be exploited to assess the element's health. In the study presented in this paper, we created a 3D finite element model to mimic a transducer bonded to the abutment of a dental implant placed in a host bone site. We simulate…
