It is generally accepted that the recent economic crisis of 2007-2010 has caused widespread economic recession in different countries. Since the ports and coastal regions are of great importance to economic infrastructure, this study examined the possible impact resulting from such a global...

The study attempts to report the motivating factors of women entrepreneurs of Agartala to become self-employed through beauty parlor business and to assess their strategies for sustainability in a competitive environment. Using cross-sectional research design, a survey through interview-Schedule...

The paper introduces a general purpose prototype able to dynamically generate visually enriched routes starting from simple input data as start, stop, intermediary coordinates, and a feed-back e-mail address. The results are portable documents (.pdfs) with many pages, each having info about the...

The study is focused on the geomorphological analysis of the Guatemala Trench, East Pacific Ocean. Research goal is to find geometric variations in western and eastern flanks of the trench and correlation of the submarine geomorphology with geologic settings and seismicity through numerical and...

It appears intuitive that technological advances and economic growth are closely related. This is evident by the fact that technologically advanced nations also have a developed economy. Technological advances of a country are based on the research done in various areas by the respective nation....

The author presents a geospatial analysis of the Peru-Chile Trench located in the South Pacific Ocean by the Generic Mapping Tool (GMT) scripting toolset used to process and model data sets. The study goal is to perform geomorphological modelling by the comparison of two segments of the trench...

We present and evaluate a numerical optimization method (together with an algorithm for choosing the starting values) pertinent to the constrained optimization problem arising in the estimation of the GARCH models with inequality constraints, in particular the Simplified Component GARCH Model...

A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and I concentrate on the numerics and...

We estimate time varying risk sensitivities on a wide range of stocks' portfolios of the US market. We empirically test, on a 1926-2004 Monthly CRSP database, a classic one factor model augmented with a time varying specification of betas. Using a Kalman filter based on a genetic algorithm, we...
