The main purpose of this article is to present the use of R programming language in cartographic visualization demonstrating using machine learning methods in geographic education. Current trends in education technologies are largely influenced by the possibilities of distance-learning,...

This paper analyzes two scripting approaches for topographic and geodetic visualization and geomorphological modeling of Bulgaria: R language and Generic Mapping Tools (GMT). The data include high-resolution raster grids: topographic datasets (GEBCO, SRTM), geoid model based on Earth...

The research problem is about to generate artificial fractal landscape surfaces from the Digital Elevation Model (DEM) using a stochastic algorithm by Geographic Resources Analysis Support System Geographic Information System (GRASS GIS) software. Fractal surfaces resemble appearance of natural...

The aim of this commentary is to show how the use of formal models — both closed-form and computational — can improve theory development and theory testing in organization theory. I also provide practical suggestions (aimed at PhD students and researchers considering to develop a formal...

In this paper, we investigate model-independent bounds for option prices given market instruments.This super-replication problem can be written as a semi-infinite linear programming problem. As these super-replication prices can be large and the densities Q which achieve the upper bounds quite...

An enhanced option pricing framework that makes use of both continuous and discontinuous time paths based on a geometric Brownian motion and Poisson-driven jump processes respectively is performed in order to better fit with real-observed stock price paths while maintaining the analytical...

Using a “plug” figure or “slack term” within a pro forma analysis is the standard method to make a forecasted balance sheet have assets equal liabilities and equity. The plug is usually stock or long-term debt because either one or a combination of the two, are assumed to be the source...

Conventional financial advice is that net present value (NPV) is a superior investment criterion to internal rate of return (IRR) because IRR has pitfalls. Despite the pitfalls, evidence shows most practitioners continue to employ IRR as an investment criterion. Such behavior is puzzling. This...
