We review the pricing of synthetic CDO tranches from the point of view of factor models. Thanks to the factor framework, we can handle a wide range of well-know pricing models. This includes pricing approaches based on copulas, but also structural, multivariate Poisson and affine intensity models. Factor models have become increasingly popular since there are associated with efficient semi-anal...

In this paper, we focus on what we call “European Proxy” of structural models, or shortly “ProxyStructural models” for credit derivatives. In standard structural models, default arrives as the first hit of a stochastic process to a barrier, hence involving a path-dependent condition. In “Proxy-Structural models”, by contrast, the path condition modeling the default indicator function is replace...

Continuous Descent Operations (CDO) has been recognized as an effective way to significantly reduce fuel burn and noise impact. Designing efficient flexible arrival routes for generating conflict-free economical trajectories is a cornerstone fully achieving CDO by high-level automation in high-density traffic scenarios. In this research, inspired the Point Merge (PM), we design Inverted Crown-S...

Introduction. Non-ferrous smelters are one of the critical nanoscale cadmium particles sources in workplace and ambient air. Materials methods. The research was performed to evaluate subchronic toxicity oxide nanoparticles (CdO-NPs) white outbred rats. Male 3.5-month old rats received intraperitoneal injections CdO-NPs 3 times a week for six weeks (18 total) doses 0.25 mg/kg body mass. After en...

Cadmium oxide has found its applications in various areas of research such as solar cells, phototransistors, photodiodes, transparent electrodes and gas sensors. In the present work CdO nano particles were successfully synthesized from cadmium acetate through thermal decomposition at high temperatures by adopting the solid state reaction. The prepared nano particles are subjected to ball millin...

We develop a method that o¤ers consistent and computationally e¢ cient credit risk analysis of cash‡ow CDO structures. The proposal makes use of simple portfolio models that admit semi-analytic representations of the loss distribution, combined with detailed and fast calculations of realistic interest and principal cash‡ow waterfalls. We de…ne in this context and study credit tranche risk measu...

We compare the performance of various hedging strategies for index collateralized debt obligation (CDO) tranches across a variety of models and hedging methods during the recent credit crisis. Our empirical analysis shows evidence for market incompleteness: a large proportion of risk in the CDO tranches appears to be unhedgeable. We also show that, unlike what is commonly assumed, dynamic model...

An ab initio pseudopotential method based on density functional theory, generalized gradient corrections to exchange and correlation, and projector-augmented waves is used to investigate structural, energetical, electronic and optical properties of MgO, ZnO, and CdO in rocksalt, cesium chloride, zinc blende, and wurtzite structure. In the case of MgO we also examine the nickel arsenide structur...

This paper describes the accidental poisoning of five workers by cadmium fume. The men were dismantling a frame of girders in a confined space by cutting bolts with an oxyacetylene burner. They were unaware at the time that the bolts were cadmium-plated or that this presented a serious industrial hazard. The paper sets out to give an appreciation of acute cadmium poisoning, the characteristics ...

CdS crystallites with rod- and flower-like architectures were synthesized using a facile hydrothermal growth method. The hexagonal crystal structure of CdS dominated the growth mechanisms of the rod- and flower-like crystallites under specific growth conditions, as indicated by structural analyses. The flower-like CdS crystallites had a higher crystal defect density and lower optical band gap v...
