Modeling and Simulation Second Edition Springer

Industrial and applied mathematics, 2020

The Industrial and Applied Mathematics series publishes high-quality research-level monographs, lecture notes and contributed volumes focusing on areas where mathematics is used in a fundamental way, such as industrial mathematics, bio-mathematics, financial mathematics, applied statistics, operations research and computer science.

This introductory tutorial is an overview of simulation modeling and analysis. Many critical questions are answered in the paper. What is modeling? What is simulation? What is simulation modeling and analysis? What types of problems are suitable for simulation? How to select simulation software? What are the benefits and pitfalls in modeling and simulation? The intended audience is those unfamiliar with the area of discrete event simulation as well as beginners looking for an overview of the area. This includes anyone who is involved in system design and modification -system analysts, management personnel, engineers, military planners, economists, banking analysts, and computer scientists. Familiarity with probability and statistics is assumed.

Environmental Modelling and Software, 1998

A computer program, SAM, has been developed to undertake the sophisticated task of statistical analysis and modelling for PCs, UNIX stations and mainframes. This paper illustrates the various procedures and methodologies adopted within the computer package. SAM is a useful tool for practitioners in selecting an appropriate probability distribution from a set of alternatives to represent statistical, environmental, socioeconomic, and engineering data. It also estimates the parameters of the distribution, predicts the desired percentile values, and calculates the minimum errors associated with the prediction. The package also provides extreme value, reliability and life-testing analyses that are essential in many scientific fields.

There are two rival images often offered of the state. In one the state serves like a nanny to provide for the welfare of its members; in the other it requires people to look after themselves, providing only the service of a night-watchman. But this dichotomy, which is routinely invoked in debates about public health and welfare provision in general, is misleading. What the rival images turn on is not competing pictures of how the state should function in people's lives but competing pictures of what it is to guard the freedom of its people. On the neo-liberal theory, which has been dominant over the last century or so, providing for people's freedom means leaving them to their own devices and fortunes. On the neo-republican theory, which answers to a much longer tradition, it means democratically identifying a common set of basic liberties in the exercise of which everyone should be protected by law and, if necessary, resourced. This older way of thinking about freedom has important merits missing in the newer and argues strongly against the night-watchman state.

Russia's War Against Ukraine – Complexity of Contemporary Clausewitzian War, 2024

In this working paper, we ask how have new technologies affected the Clausewitzian fog of war? We leverage examples from Russia’s ongoing full-scale invasion of Ukraine to address this research question. The evidence includes both “high-tech” systems like nuclear-capable hypersonic weapons and “low-tech” systems like cheap commercially available drones and affordable open-source intelligence (OSINT) technology. In the case of the former, we find that Russian threats and propaganda created myths surrounding weapons with unclear military applications. Regarding the latter, media and pundit claims were sensational as these systems changed combat dynamics without delivering revolutionary effects. Both cases point to pronounced gaps between expectations about performance and battlefield realities. Emerging weapon technologies have therefore failed to provide clarity about the balance of forces and conditions on the ground––two pathways to reducing the fog of war. In land warfare, history has long shown that new technologies are rarely determinative of victory or defeat. Making claims to the contrary only contributes to the fog of war and necessitates new strategies to counter the hype surrounding exaggerated expectations about weapons.

Popular Music Research Today: Revista Online de Divulgación Musicológica, 2022

La utilización de la música electrónica en los audiovisuales ha recorrido un largo camino hasta la actualidad. En este sentido, aunque la música electrónica sigue asociándose en la imagen con los clichés de los géneros de la ciencia ficción, el terror o la tecnología, ha pasado a formar parte de productos audiovisuales de otros géneros, y sus múltiples hibridaciones, además de construir nuevas capas de significación y diferentes formas de identificación con el público en el apogeo de la era digital o metamodernidad. Las nuevas herramientas para la producción musical –DAW (Digital Audio Workstation) y VST Plug-ins (Virtual Studio Technology)– han posibilitado la creación de nuevas sonoridades y paisajes audiovisuales. De manera paralela, este software ha mediado en la construcción de un imaginario colectivo que pone sus ojos en los productos audiovisuales de los años ochenta del siglo pasado, y en especial en los videojuegos y su música de 8 y 16 bits, como periodo canónico de la cultura popular. La creación de nuevos instrumentos virtuales, inspirados en las sonoridades de aquella década, y la reutilización mediante «sampleo» de cajas de ritmos, bass lines y sintetizadores de los ochenta, como «retrotecnia» y «technostalgia», han experimentado un continuo crecimiento en las más recientes producciones audiovisuales y han posibilitado narrativas transmedia. La mirada nostálgica a los productos canónicos de aquella época se ha ampliado progresivamente a la década de los noventa y a momentos más recientes. En este artículo nos centraremos en diferentes productos audiovisuales (películas y series de plataformas en streaming) de la última década. Analizaremos algunas de estas producciones con el objetivo de conocer la manera en que las herramientas digitales de producción musical, y en concreto ciertos instrumentos virtuales vinculados a la cultura de baile y la música rave, median en la construcción de significados, la creación de identidades digitales y la gestión de las emociones de los espectadores.
