Abstract A reasonable concept for the true trade price index in situations where low-price countries capture market shares from high-price is average paid by importers same quality of good or service all exporting countries. However, decompositions indices are usually inexact sense that used as underlying aggregator formula not exactly reproduced. In this paper, we compare analytically exact an...

the present research aims to evaluate impacts of crude oil price return index, bloomberg petroleum index and bloomberg energy index on stock market returns of 121 companies listed in tehran stock exchange in a 10 years' period from early 2006 to april 2016. first, explanatory variables were aligned with petroleum products index mostly due to application of dollar data. subsequently, to che...

This study proposes a new linear approximation for solving the dynamic response equations of a rocking rigid block. Linearization assumptions which have already been used by Hounser and other researchers cannot be valid for all rocking blocks with various slenderness ratios and dimensions; hence, developing new methods which can result in better approximation of governing equations while keepin...

Early in January 1984, beneficiaries under the OldAge, Survivors, and Disability Insurance (OASDI) program received a 3.5-percent cost-of-living increase. This increase, effective for December 1983, was originally scheduled to take effect in June but was postponed by the 1983 Amendments to the Social Security Act. . Automatic cost-of-living increases were instituted in 1975 by legislation enact...

In this paper, a Takagi–Sugeno–Kang (TSK) type Fuzzy Rule Based System is developed for stock price prediction. The TSK fuzzy model applies the technical index as the input variables and the consequent part is a linear combination of the input variables. The fuzzy rule based model is tested on the Taiwan Electronic Shares from the Taiwan Stock Exchange (TSE). Through the intensive experimental ...

We present a column-generation model and branch-and-price-and-cut algorithm for origin-destination integer multicommodity flow problems. The origin-destination integer multicommodity flow problem is a constrained version of the linear multicommodity flow problem in which flow of a commodity (defined in this case by an origin-destination pair) may use only one path from origin to destination. Br...
