Global climate policies, local institutions and food security in a pastoral society in Ethiopia

2011

This paper explores climate change adaptation within national policy priorities in a least developed country (LDC). The premise of the article is that when considering food security, climate is an exogenous trigger, while the deeper causes lie in social problems. Therefore, adaptation is subordinate to poverty alleviation. The paper examines how these two goals, climate adaptation and poverty alleviation, can be combined. Recent studies have shown that the most effective way to adapt to changing climate conditions in a poor country is to rely on local institutions that have established and sustainable mechanisms to deal with extreme climatic conditions. This research analyzes the stakeholde…

Measurement of the Higgs boson coupling with tau leptons and search for an additional neutral MSSM Higgs boson with the ATLAS detector

2018

El Modelo Estándar de física de partículas (SM), la teoría que describe el comportamiento de las partículas subatómicas, ha sido un éxito en su precisión y exactitud. Uno de sus pilares básicos es el mecanismo de Higgs, que regula los términos de masa de las partículas fundamentales. La partícula responsable de este mecanismo es el bosón de Higgs, que fue descubierto en 2012 en los experimentos ATLAS y CMS del colisionador de partículas LHC del CERN, mediante el análisis de su acoplamiento a partículas bosónicas (fotones y bosones W y Z). Tras su descubrimiento, es necesario confirmar que el resto sus propiedades se corresponden con las predichas por el SM, como, por ejemplo, su acoplamient…

Standard testing of photovoltaic modules for use in renewable energy education

2015

A photovoltaic laboratory exercise has been devised and used in the educational curriculum of the Renewable Energy Programme at the University of Jyväskylä. The purpose of the experimental tasks is to give students of renewable energy a good understanding of standard testing procedures used in industry for characterising photovoltaic modules and to provide practical skills in sizing simple photovoltaic installations. Herein the experimental set-up, basic theory and measurement procedure are described. The experimental apparatus is simple to assemble and uses both standard laboratory equipment and recycled components. From the experimental results, the tested PV cell had a maximum efficiency…

A Proposal of Process Fragment Definition and Documentation

2012

This paper focuses on the field of Situational Method Engineering (SME) for the construction of agent-oriented design processes. Whatever SME approach a method designer wants to use, he has to manage two main elements: the (method or process) fragment and the repository where it is stored. Specific fragment definition and documentation are fundamental during these activities, for new process composition, and for the consequent system design activities. This paper aims at illustrating a proposal of fragment definition and documentation. This proposal is aimed to be an input for the IEEE FIPA Design Process Documentation and Fragmentation working group and, as regards our own research work, t…

Pseudospectrum of Reissner-Nordström black holes: Quasinormal mode instability and universality

2021

Black hole spectroscopy is a powerful tool to probe the Kerr nature of astrophysical compact objects and their environment. The observation of multiple ringdown modes in gravitational waveforms could soon lead to high-precision gravitational spectroscopy, so it is critical to understand if the quasinormal mode spectrum is stable against perturbations. It was recently shown that the pseudospectrum can shed light on the spectral stability of black hole quasinormal modes. We study the pseudospectrum of Reissner-Nordstr\"om spacetimes and we find a spectral instability of scalar and gravitoelectric quasinormal modes in subextremal and extremal black holes, extending similar findings for the Sch…

Il dynamic business model: una prospettiva dinamica per la progettazione dei modelli di business

2017

Building on the extant literature on business modelling and focussing on start-up firms, this article aims at exploring the combination between conventional business model schemes and System Dynamics methodology with the intent to overcome those limitations related to a static design approach. By mapping the multiple key elements underlying value creation processes – linked according to a cause-and-effect perspective – and with the support of a simulation-based methodology, entrepreneurs may experiment and understand how the firm reacts to strategic and organizational changes in terms of performance, innovation and value creation.

It is very important to envestigate tbe theoretical foundations of the local govcmment before the research of its functioning. They provide the most completc ccweruge of philosophical and poiitical aspects of the phenomenon of local democracy. The scienlifrc potential of self-governing idcas discloscd in the aggregate theoretical structures, basie concepts and categories. In the concepts the common elements of the models of local govemment in their dynamics are refiectcd. Ali concepts of local government start from trying to solve the problem: Does the community have a separate, distinct from state power, whether it is independent from the state public corporation or firm incorporated in th…

IPE scholarship about Southeast Asia : Theories of development and state-market-society relations

2020

Contemporary Southeast Asia is a diverse region that is fully integrated into the world economy. Its eleven constituent countries are distinct with unique historical, political, economic, and cultural configurations – as such, they develop unevenly within, and respond accordingly to, the evolution of the global capitalist system. This chapter provides a survey of literatures, themes and debates that have significantly contributed to the study of Southeast Asia from the discipline of international political economy (IPE). It shows how specific IPE scholarship about Southeast Asia since the 1950s have been framed within the general theories of development (i.e., modernization and dependency) …

Modeling and Backstepping Control of the Electronic Throttle System

2013

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/871674 Open access Electronic throttle is widely used in modern automotive engines. An electronic throttle system regulates the throttle plate angle by using a DC servo motor to adjust the inlet airflow rate of an internal combustion engine. Its application leads to improvements in vehicle drivability, fuel economy, and emissions. In this paper, by taking into account the dynamical behavior of the electronic throttle, the mechanism model is first built, and then the mechanism model is transformed into the state-space model. Based on the s…
