Performance Degradation of Discrete PID Controller for Digital Excitation Control System Due to Variation of Sampling Time
2019
Modern digital AVR are consisting PID controller in forward path ensures fast response in the event of disturbance. Digital keypad is used for setting PID gains to improve performance of the system. Digital PID controller reads the error signal at regular interval unlike analog controller that reads the error signal continuously. Regular interval at which digital processor reads error signal is called sampling time that has substantial effect on the performance of the controller and consequently affects the stability of the power system where synchronous generator using digital excitation system is connected in parallel. This paper addresses the issues of variation of sampling time on the p…
Applying Spring Security Framework with KeyCloak-Based OAuth2 to Protect Microservice Architecture APIs: A Case Study
2022
In this study, we implemented an integrated security solution with Spring Security and Keycloak open-access platform (SSK) to secure data collection and exchange over microservice architecture application programming interfaces (APIs). The adopted solution implemented the following security features: open authorization, multi-factor authentication, identity brokering, and user management to safeguard microservice APIs. Then, we extended the security solution with a virtual private network (VPN), Blowfish and crypt (Bcrypt) hash, encryption method, API key, network firewall, and secure socket layer (SSL) to build up a digital infrastructure. To accomplish and describe the adopted SSK solutio…
Corporate e-Governance Disclosure in the Digital Age: An Empirical Study of Spanish Listed Companies
2005
Corporate governance research has focused mainly on the analysis of the information that firms ought to disclose and the effects of disclosure, basically without considering the media involved. This paper examines the relevance of technology, and particularly the internet, for the improvement of corporate governance and transparency in listed companies. The need for this study is clear in view of the increasing interest shown by supervisory authorities for the oversight of the European and US capital markets in regulating not only content but also the manner in which corporate governance information is disclosed over the internet. In this paper we have quantified three corporate governance …
Honouring the opening: Unfolding the rich ground between the philosophical thinking of Martin Heidegger and practice-based empirical work
2021
The aim of this article is to bring philosophical thinking closer to practice-based empirical work. Using Martin Heidegger’s philosophy, it offers a bridge between these two worlds, attempting to provide philosophical depth to the findings of a hermeneutic phenomenological study. This process unfolded through the appearance of three intertwined, potential, meaningful modes of being in the lifeworld: space as a condition for being and being for worlding the world; temporal and spatial self-being, the existence of multiple selves in time and space; and suffering and thriving as modes of being. The article extends the dialogue and concludes with key reflections and insight for research practic…
Les mouvements de capitaux en union économique et monétaire : approches historiques et théoriques
2019
The liberalization of international capital flows seems linked to the increase and worsening of financial crisis. Since the financial crisis in 2007-2008, the ideological dimension of “happy globalization” has brought to light and given new strength to dissentient voices that could not be heard before. This thesis tries to evaluate the importance of capital flows on the stability of à financial system. Its purpose is to compare different financial systems and levels of financial liberalization, using the Economic and Monetary Union as an example because it combined full liberalization of the capital market within the zone a well as in relations with the outside. We have considered the need …
Money and the natural rate of interest: structural estimates for the United States and the Euro area
2008
We examine the role of money, allowing for three competing environments: the New Keynesian model with separable utility and static money demand; a non-separable utility variant with habit formation; and a version with adjustment costs for holding real balances. The last two variants imply forward-looking behavior of real money balances, as it is optimal for agents to allow their forecast of future interest rates to affect current portfolio decisions. We distinguish between these specifications by conducting a structural econometric analysis for the U.S. and the euro area. FIML estimates confirm the forward-looking character of money demand. Using these estimates we find that, in response to…
The New Consensus and Post-Keynesian Interest Rate Policy.
2007
Abstract This paper outlines the fundamental arguments of the New Consensus, critiques it from a Post-Keynesian perspective, and offers a Post-Keynesian alternative to the Taylor Rule. While Post-Keynesian economics provides a theory of endogenous money with exogenous interest rates, it has no clear description of a central bank reaction function. We attempt to remedy this oversight by identifying some of the difficulties attached to developing a Post-Keynesian reaction function, and suggesting an approach to the setting of interest rates that is more consistent than the Taylor Rule with Keynes's General Theory.
Long-term properties and end-of-life of polymers from renewable resources
2017
[EN] The long-term properties and end-of-life of polymers are not antagonist issues. They actually are inherently linked by the duality between durability and degradation. The control of the service-todisposal pathway at useful performance, along with low-impact disposal represents an added-value. Therefore, the routes of design, production, and discarding of bio-based polymers must be carefully strategized. In this sense, the combination of proper valorisation techniques, i.e. material, energetic and/ or biological at the most appropriate stage should be targeted. Thus, the consideration of the end-of-life of a material for a specific application, instead of the end-of-life of a material s…
ES enerģijas politika un Turcijas loma energoapgādes drošības kontekstā.
2015
Ņemot vērā vietējo energoresursu trūkumu, ES ir bijusi enerģijas importētājas pozīcijā jau kopš tās dibināšanas. Lai gan energoapgādes drošība galvenokārt ir bijusi ES darba kārtībā, tikai nesen ir veikti stingri drošības pasākumi. Konflikts starp Ukrainu un Krieviju sākās 2013. gadā un parāda, cik steidzama un stingra rīcība ir nepieciešama, lai tiktu nodrošināta droša energoapgāde. Saistībā ar iepriekš minēto, enerģijas piegāžu diversifikācija ieņem ļoti īpašu lomu dalībvalstu dienaskārtībā kopā ar to uzticamo sabiedroto - Turciju. Šī pētījuma mērķis ir izskaidrot kā ES enerģētiskā atkarība ir mainījusies laika gaitā, analizēt esošos energoapgādes drošības pasākumus un pierādīt Turcijas l…
ERCP : Energy-Efficient and Reliable-Aware Clustering Protocol for Wireless Sensor Networks
2022
Wireless Sensor Networks (WSNs) have been around for over a decade and have been used in many important applications. Energy and reliability are two of the major problems with these kinds of applications. Reliable data delivery is an important issue in WSNs because it is a key part of how well data are sent. At the same time, energy consumption in battery-based sensors is another challenge. Therefore, efficient clustering and routing are techniques that can be used to save sensors energy and guarantee reliable message delivery. With this in mind, this paper develops an energy-efficient and reliable clustering protocol (ERCP) for WSNs. First, an efficient clustering technique is proposed for…
