In many domains, the combined opinion of a committee of experts provides better decisions than the judgment of a single expert. This paper shows how to implement a successful ensemble strategy for predicting recovery rates on defaulted debts. Using data from Moody’s Ultimate Recovery Database, it is shown that committees of models derived from the same regression method present better forecasts...

Hydraulic fracturing is one of the most common methods of well stimulation for reservoirs with low permeability. Hydraulic fracturing increases the flow capacity, alters flow geometry, bypasses damage and improves recovery factor. The pressure of most of Iranian oil reservoirs is declined and consequently the production is reduced. It is necessary to improve the production by using new stimulat...

This paper investigates interoperability problems arising from the use of dissimilar key recovery mechanisms in encrypted communications. The components that can cause interoperability problems are identified and a protocol is proposed where two communicating entities can negotiate the key recovery mechanism(s) to be used. The ultimate goal is to provide the entities a means to agree either on ...

Gothic Art and Architecture, religious and secular buildings, sculpture, stained glass, and illuminated manuscripts and other decorative arts produced in Europe during the latter part of the Middle Ages (5th century to 15th century). Gothic art began to be produced in France about 1140, spreading to the rest of Europe during the following century. The Gothic Age ended with the advent of the Ren...

A team of students from City College of New York and the Bronx Community College, as well, traveled to the Yampa River Valley in the northwest of the Colorado State to conduct experiments related to the contamination of the air in January 2005. The objective of this report is to investigate if pollution from the valley reached Storm Peak Laboratory (SPL). According to the studies made on the tw...

The aim of this paper is to explain the divergent developmental outcomes between South Korea, Taiwan, and South Vietnam. Whilst US aid has correctly been cited as key factor in explaining the rapid post-war development of South Korea and Taiwan, the ultimate failure to establish strong institutions in South Vietnam calls for a closer analysis of how differing historical and geopolitical factors...

A typical Iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. The modeling was carried out by using a fine-scaled Eclipse model in the single porosity mode (the fractures were explicitly modeled). The model was extended to a stack of 6 matrix blocks to understand block-to-...

In man and in subhuman primates the paresis produced by lesions of the motor cortex is variable in respect of rate and of extent of ultimate recovery of motor power, Clinically various factors influencing recovery are recognized, such as the size and nature of the lesion and its location in the cerebral hemispheres, but the extent of recovery is generally unpredictable. In an experimental study...
