Much reusable software is available for solving routine mathematical and statistical problems. Unfortunately, locating this software is often quite diicult in current distributed computing environments. The Guide to Available Mathematical Software (GAMS) virtual software repository seeks to remedy this by providing users with convenient access to thousands of software modules physically distrib...

This paper describes the PSAT-GAMS interface to solve a variety of optimization models. The Power System Analysis Toolbox (PSAT) is an open source Matlab-based software package for analysis and design of small to medium size electric power systems. While the General Algebraic Modeling System (GAMS) is a high-level modeling system for mathematical programing problems. It consists of a language c...

A complete synthetic medium containing 15 amino acids, a minimal synthetic medium (GAMS) containing 4 amino acids, and a supplemented minimal medium (GAMS + calcium pantothenate) have been developed for the cultivation of Hyphomicrobium neptunium ATCC 15444. Depending on the complexity of the synthetic media, generation times were approximately 2 to 3 times longer, and maximum cell densities we...

away from the underlying programming languagein favour of using graphical means of programming, suchas wizards and statecharts. Platforms. Closed frameworks such as DESIRE, strongly based on a platform, provide more complete solutions thanothers such as Jadex or TuCSoN. They usually offer anagent architecture and a system model, very useful fornovel developers, together with...

This document gives a short introduction into Spatial Equilibrium modeling with GAMS. 1. Intertemporal-Spatial Price Equilibrium Solving spatial equilibrium models by mathematical programming is pioneered by [9],[12], [11], and [13]. One of the most basic forms is the transportation problem, also known as the “Koopmans-Hitchcock” model. An example is found in the GAMS model library in trnsport....

The paper presents applications of a class of semi-parametric models called generalized additive models (GAMs) to several business and economic datasets. Applications include analysis of wage-education relationship, brand choice, and number of trips to a doctor’s office. The dependent variable may be continuous, categorical or count. These semiparametric models are flexible and robust extension...

Biolog EcoPlates™ can be used to measure the carbon substrate utilisation patterns of microbial communities. This method results in a community-level physiological profile (CLPP), which yields a very large amount of data that may be difficult to interpret. In this work, we explore a combination of statistical techniques (particularly the use of generalised additive models [GAMs]) to improve the...

Positive allosteric modulators of GABAA receptors (GAMs) acting at specific subtypes of GABAA receptors effectively restore compromised spinal pain control in rodents. Studies addressing a similar antihyperalgesic effect in humans are sparse and are hampered by sedative effects of nonselective GAMs available for use in humans. We present results from a randomized controlled double-blind crossov...
