It is difficult to compute Value-at-Risk (VaR) using multivariate models able to take into account the dependence structure between large numbers of assets and being still computationally feasible. A possible procedure is based on functional gradient descent (FGD) estimation for the volatility matrix in connection with asset historical simulation. Backtest analysis on simulated and real data pr...

The objective of the present paper is to analyse syntactic ambiguity of prepositional groups (Pg’s) within the background of dependency oriented Functional Generative Description (FGD). Several basic types of Pg-ambiguity are presented and the possibilities of searching for their occurrences in the Prague Dependency Tree Bank (PDT) is illustrated. Criteria for automatic Pg-ambiguity detection a...

combustion flue gas desulfurization (FGD) using lime or limestone are the primary processes employed to reduce sulfur dioxide (SO 2 ) emission from coal combustion. However, these processes generate voluminous solid wastes, i.e., pyrite and gypsum, that are usually landfilled, occupying thousands of acres of land and creating serious land and water pollution problems due to the release of acids...

This research is a part of a wide range investigation on the use of flue gas desulphurisation (FGD) in construction applications. It reports some results on the porosity and pore size distribution of cement paste containing varying amounts of fly ash-gypsum blends as partial replacement of cement. The cement was replaced with 25% of different blends of fly ash and gypsum. The gypsum content ran...

The paper presents details and comparison of two valuable language resources for Czech, two independent verb valency frames electronic dictionaries. The FIMU verb valency frames dictionary was designed during the EuroWordNet project and contains semantic roles and links to the Czech wordnet semantic network. The VALLEX 1.0 format is based on the formalism of the Functional Generative Descriptio...

Background & aim: Male involvement is evidently an effective strategy for enhancing maternal health outcomes. Although childbirth has traditionally targeted women, the key roles of men in decision-making and financial support cannot be ignored. This study aimed to analyze women’s perception of men in birth preparedness in Migori County, Kenya. Methods: This qualitative study was conducted on 32...
