Recourse against Judgments in the Netherlands
No full textIn the 1980s, the Netherlands witnessed the start of a comprehensive programme of reform in the fields of judicial organisation and procedure. The reform programme consists of three stages, of which the first has now been completed. This has, amongst other things, resulted in the consolidation of several administrative procedures which were formerly adjudicated by different judicial bodies, in the Arrondissementsrechtbank. Consequently, the Arrondissementsrechtbank has obtained extensive administrative jurisdiction together with its jurisdiction in civil and criminal cases. As part of the reforms in the second stage, a bill has been submitted to Parliament which contains changes in the court structure. It is proposed to abolish the Kantongerecht and to reallocate its jurisdiction to the Arrondissementsrechtbank, transforming the latter court into a general first-instance court. In addition, the bill contains changes in the Code of Civil Procedure. In the present report the author discusses the current situation January 1998
In control. Methodological and clinical aspects of cerebral autoregulation and haemodynamics
No full textCerebral autoregulation (CA) is a key mechanism to protect the brain against excessive fluctuations in blood pressure (BP) and maintain cerebral blood flow. Analysing the relationship between spontaneous BP and cerebral blood flow velocity (CBFV) using transfer function analysis is a widely used technique to quantify CA in a non-invasive way. The objective of this review was to provide an overview of transfer function techniques used in the assessment of CA. For this review, 113 publications were included. This literature showed that there is no gold standard for the execution and implementation of the transfer function. There is a high diversity in settings and criteria used for transfer function analysis. Notable is also the high number of studies which report little on the settings. This disparity makes it difficult to replicate or compare the results of the different studies and further hinders the opportunity to make a distinction between intact and impaired CA in different patient groups. More research on the effects of different implementation techniques on outcomes for CA and optimization of the transfer function analysis is urgently needed. Furthermore, the results of this review show that international guidelines should be created to inform the minimal description of the applied technique and the interpretation of transfer function outcomes in scientific research
On the Determination of the Number and Multiplicity of Zeros of a Function
No full textIt is shown that certain simple integrals determine the number of zeros with a certain multiplicity of a function of one variable in an arbitrary interval. Several typical numerical examples are given.
On the Calculation of the Exact Number of Zeroes of a Set of Equations
No full textThe number of simple zeroes common to a set of nonlinear equations is calculated exactly and analytically in terms of an integral taken over the boundary of the domain of interest. The integrand consists only of simple algebraic quantities containing the functions involved as well as their derivatives up to second order. The numerical feasibility is shown by some computed examples.
Bifurcation Routes in Financial Markets
No full textThe heterogeneity of expectations among traders introduces an important non-linearity into the financial markets. In a series of papers, Brock and Hommes, propose to model economic and financial markets as adaptive belief systems. Asset price fluctuations in adaptive belief systems are characterized by phases of close-to-the-fundamental-price fluctuations, phases of optimism where most agents follow an upward price trend, and phases of pessimism with small or large market crashes. In this paper will be discussed the EMH benchmark and forecasting rules of fundamentals and trend extrapolators. Some illustrative examples are supplied.heterogeneity of expectations, adaptive belief systems, forecasting rules, fundamentals, trend extrapolators equations, limit cycles, asymptotical stability
Extracting cyclostationary features from single carrier signals
No full textThis paper contributes to the discussion about the usefulness of cyclostationary feature detection for the purpose of cognitive radio. From a simple but realistic radio signal model and an ideal channel, the power spectral density of the random signal component is derived, and compared with the periodical component that can be retrieved from the signal with a nonlinear operation
On the theory of the reconstruction of a weak phase-amplitudeobject from its images, especially in electron microscopy: III. Low-dose imaging using oblique illumination
No full textSignal Processing and Restoration
No full textDigital Signal Processing (DSP) concerns the theoretical and practical aspects of representing information-bearing signals in digital form and the use of processors or special purpose hardware to extract that information or to transform the signals in useful ways. Areas where digital signal processing has made significant impact include telecommunications, man-machine communications, computer engineering, multimedia applications, medical technology, radar and sonar, seismic data analysis, and remote sensing, to name a few
