Isobaric vapor–liquid equilibrium for ternary mixtures of ethanol and methylcyclohexane with 3-methylpentane and tert-butyl alcohol at 101.3kPa
2007
Abstract Consistent vapor–liquid equilibrium (VLE) data for the ternary systems 3-methylpentane + ethanol + methylcyclohexane and ethanol + tert-butyl alcohol (TBA) + methylcyclohexane are reported at 101.3 kPa. The VLE data have been correlated by Wilson, UNIQUAC and NRTL equations. The ternary systems do not present azeotrope and are well predicted from binary interaction parameters.
Farmer-Herder Conflict in Africa: An Assessment of the Causes and Effects of the Sedentary Farmers-Fulani Herdsmen Conflict : A Case Study of the Ago…
2017
Master's thesis Global development and planning UT505 - University of Agder 2017 Violent conflicts, particularly farmer-herder conflicts have, for a long time, been a common feature of economic livelihood in West Africa (Bleach, 2004). This thesis explores the causes and the effects of farmer-Fulani herdsmen conflict, and the mitigation responses towards the conflict. The resource scarcity, eco-survivalism and social capital theories (Hommer-Dixon, 1999; Okoli, 2013; Bourdieu, 1986) serve as the main theoretical point of discussion for this study. Using Agogo in Ghana as a case study, the study empirically examines the reasons behind the movement of the Fulani herdsmen to Agogo, the causes …
Embedding the Remote Application Control: Visual API for PDA Programming
2009
PDAs are more and more used as advanced adaptive HEI (human-environment interaction) interfaces, thus enabling their users to easily operate applications remotely running in pervasive computing scenarios. Based on a previous implementation, in this paper we discuss the development of a new set of .NET-compliant Application Programming Interfaces to be used within the Visual Studio IDE. Our main goal is to provide programmers with a set of components to be used with the common drag-and-drop operation, in order to embed a remote application control within an application running on the PDA and vice-versa. The interaction relies on ad-hoc communication protocols over a framework devoted to pair…
Ontonuts: Reusable Semantic Components for Multi-agent Systems
2009
The volumes of data in information systems are growing drastically. The systems become increasingly complex in trying to handle heterogeneity of ubiquitous components, standards, data formats, etc. According to the vision of Autonomic Computing, the complexity can be handled by introducing self-manageable components able to "run themselves." Agent Technology fits this vision, whereas interoperability among autonomic components can be tackled by Semantic Technologies. The problem of efficient heterogeneous data sharing, exchange and reuse within such systems plays a key role. We present an approach of constructing semantic capabilities (self-descriptive functional components) for software ag…
A Security Framework for Smart Ubiquitous Industrial Resources
2007
Conventional approaches to manage and control security seem to have reached their limits in new complex environments. These environments are open, dynamic, heterogeneous, distributed, self-managing, collaborative, international, nomadic, and ubiquitous. We are currently working on a middleware platform focused on the industrial needs, UBIWARE. UBIWARE integrates Ubiquitous Computing with Semantic Web, Distributed AI, Security and Privacy, and Enterprise Application Integration. In this paper, we describe our long-term vision for the security and privacy management in complex multi-agent systems like UBIWARE, SURPAS. The security infrastructure has to become pervasive, interoperable and inte…
Problems and Perspectives of the EU-Ukraine Cooperation in the Area of Tourism in the Process of Implementing the Association Agreement
2017
W artykule przedstawiono specyfikę współpracy między UE a Ukrainą w sferze turystyki w kontekście realizacji polityki turystycznej UE i perspektyw gospodarczych. Omówiono problemy i perspektywy wspólnych działań w sferze turystyki jako jednej z głównych dróg Ukrainy do integracji europejskiej, a także polityczne i prawne aspekty współpracy między UE a Ukrainą w sferze turystyki w ramach realizacji umowy o stowarzyszeniu
Współpraca transgraniczna jako czynnik transformacji międzynarodowych funkcji granicy ukraińsko-polskiej
2014
W artykule dokonano analizy właściwości ukraińsko-polskiej współpracy transgranicznej, która jest realizowana w ramach współpracy między regionami przygranicznymi sąsiadujących ze sobą państw i przejawia się w różnych formach. Przeanalizowano wpływ współpracy transgranicznej na funkcjonowanie ukraińsko-polskiej granicy państwowej, w szczególności wzmacnianie jej funkcji kontaktowej i międzynarodowej. Zbadano determinanty funkcjonowania euroregionów, obejmujących tereny przygraniczne Polski i Ukrainy. Jako jedno z istotnych wyzwań w tym zakresie na współczesnym etapie należy rozpatrywać konieczność doskonalenia infrastruktury transportowej, modernizacja której będzie sprzyjała poprawie funkc…
Beurling ultradistributions of Lp-growth
2003
We study the convolutors and the surjective convolution operators acting on spaces of ultradistributions of Lp-growth. In the case p = 2 we obtain complete characterizations. Some results on hypoellipticity are also included. 2003 Elsevier Science (USA). All rights reserved.
Unbounded derivations and *-automorphisms groups of Banach quasi *-algebras
2018
This paper is devoted to the study of unbounded derivations on Banach quasi *-algebras with a particular emphasis to the case when they are infinitesimal generators of one parameter automorphisms groups. Both of them, derivations and automorphisms are considered in a weak sense; i.e., with the use of a certain families of bounded sesquilinear forms. Conditions for a weak *-derivation to be the generator of a *-automorphisms group are given.
Continuous frames for unbounded operators
2021
Few years ago G\u{a}vru\c{t}a gave the notions of $K$-frame and atomic system for a linear bounded operator $K$ in a Hilbert space $\mathcal{H}$ in order to decompose $\mathcal{R}(K)$, the range of $K$, with a frame-like expansion. These notions are here generalized to the case of a densely defined and possibly unbounded operator on a Hilbert space $A$ in a continuous setting, thus extending what have been done in a previous paper in a discrete framework.
