Excess spread efficiency

We will discuss portfolio yield, monthly payment rate (MPR), delinquencies, charge-offs, and excess spread as well as excess spread efficiency (ESE) and charge-off coverage (COC) the latter two are combinations of the first five performance indicators. The various performance indicators will be shown for European and US credit card collateral. We will use our BECCI for European collateral and Standard Poor s Credit Card Quality Indexes (S P Index) for US collateral.

However, we are introducing two ratios to help predict the severity of change in collateral performance with a worsening economic environment. The two ratios are excess spread efficiency (ESE) and charge-off coverage (COC). 

The central problem in efficiently using wood for the decentralised production of heat and power has been the gas clean-up process. Tars and particles need to be removed efficiently to prevent depositions or excessive wear in the power conversion devices (gas engines, gas turbines).The problems and costs associated with efficient gas cleanup, especially for the conversion or removal of tars, have not been solved so far in a satisfactory way and have hindered the wide-spread introduction of gasificahon as a means of utilising fuel wood with high exergy efficiency. 

Concentration quenching is not a major problem in semiconducting polymers. Typically, the quantum efficiency for photoluminescence from thin films is comparable to that from dilute solutions. The absence of strong concentration quenching is the result of the spatial delocalization of the excited states. Because the weakly bound excitons are spread over many repeat units, the Davidov splitting that results from interchain interactions is small. As a result, the disorder that is present in films cast from solution is sufficiently large to mix the dark and emissive Davidov-split states. Thus, quantum efficiencies in excess of 60-70% can be obtained from thin solid films of luminescent semiconducting polymers. 

In several runs, e.g. run 17, Table 4, stable operation of the anode was obtained at a rather low voltage. This was due to the effect of the anode construction (the inner current lead had been pressed into a hole in the anode body) and also that the temperature in this run was high, which resulted first in a relatively low electrical resistance of the ceramic anode and secondly in a more complete and faster metal-thermal reduction reaction. As a result tantalum powder was not spread over the container volume, but was concentrated on the cathode rod as a compact conglomerate which could be removed from the melt together with the cathode. In addition there was practically no Ta205 powder in the container and after the experiment it was not difficult to separate the tantalum powder from that of TajOj. The low current efficiency in this run is due to the non-optimized operating conditions of electrolysis in particular that an excess amount of electricity had been passed. 

Atomization by compressed air involves the use of air at high speeds to produce an aerosol. The liquid is introduced into an air stream and drops are pulverized through the energy of the gas stream [15]. Typically, the fraction of the deposited material is small due to excess spray spread. Many drops are deflected or reflected from the surface of the substrate, decreasing the deposition efficiency. In general, the droplet size grows proportional to the increase of viscosity, surface tensiou and density [1],...
