Observatility and observers for nonlinear systems with time delays
No full text"Basic properties on linearization by output injection are investigated in this paper. A special structure is sought which is linear up to a suitable output injection and under a suitable change of coordinates. It is shown how an observer may be designed using theory available for linear time delay systems.

One way to increase resilience after disasters is to install microgrids so that some services can be provided to local communities during recovery. This thesis describes a mixed integer linear program for equitably siting microgrids according to travel distance and community resources. The travel distances can be calculated using either single-destination naive trips, or optimal solutions to the generalized traveling salesperson problem (GTSP) to support multi-destination trips. However, this microgrid siting method is impractical at scale without access to computing resources currently difficult to access ""off the shelf.""
We propose a heuristic procedure, based on spanning trees, for calculating trip distances and the burden associated with them for a given set of facilities and a graph network. This procedure can be used to evaluate a given candidate microgrid placement scenario. We present a case study showing that this heuristic is a better approximation of GTSP-based distance and burden than the naive procedure when calculating multi-destination trips. Our heuristic presents a more nuanced alternative to the naive procedure without resorting to repeatedly solving the GTSP to underlie calculations of burden.
As ilhas culturais (da literatura brasileira) a partir da interpretação de Vianna Moog
No full textVianna Moog em Uma Interpretação da Literatura Brasileira – Um arquipélago cultural propõe um novo método para a compreensão do fenômeno literário em nosso país, a partir da ideia de ilhas culturais, mais ou menos diferenciadas. A primeira ilha é a Amazônica, seguindo-se o Nordeste, a Bahia, Minas Gerais, São Paulo, Rio Grande do Sul e Rio de Janeiro, fixadas por força de fatores de ordem histórica e geográfica, assim definidos. Diante disso, a presente dissertação objetiva recuperar esse texto e trazê-lo de volta aos debates acerca do fazer da História da Literatura, respondendo às seguintes questões norteadoras: Em que consiste a literatura nacional com base nas ideias do autor? O que diferencia a tese proposta por Moog das demais histórias literárias escritas até aquele momento? O que caracteriza as ilhas culturais, de acordo com o autor? Como a referida obra foi recebida e absorvida, ou não, por outros estudiosos? Para isso, além da apresentação descritiva e análise do texto de Moog, realizou-se pesquisa bibliográfica em diferentes histórias da literatura, e buscou-se diversos teóricos dedicados ao estudo da História da Literatura como David Perkins, Heidrun Olinto, Siegfried Schmidt, Roberto Acízelo de Souza, Ferdinand Denis, entre outros.Vianna Moog in Uma Interpretação da literatura brasileira - Um arquipélago cultural proposes a new method for understanding of the literary phenomenon in our country, from the idea of islands cultural, more or less differentiated. The first island is the Amazônia, followed by Nordeste, Bahia, Minas Gerais, São Paulo, Rio Grande do Sul and Rio de Janeiro, these islands are imposed by virtue of historical order factors and geographical as well defined. So, this work wants to retrieve this text and bring it back to debates about making History of Literature, answering the following questions: How the national literature can be based on the author’s ideas? What differentiates thesis proposal by Moog other literary stories written until time? What characterizes the cultural islands, according to the author? As the reference book was received and absorbed, or not, by other theorist? To do this, in addition to descriptive and analytical presentation of text Moog, bibliographic search in different stories of literature, and sought for various theoretical dedicated to the study of the history of literature as David Perkins, Heidrun Olinto, Siegfried Schmidt, Roberto Acízelo de Souza, Ferdinand Denis, among others
A identidade dos descendentes de alemães em "Um rio imita o Reno", de Vianna Moog * The identity of German descendants on “Um rio imita o Reno”, by Vianna Moog
No full textThis article will address the scope of the issues of cultural integration of German people in the work of Brazilian author Vianna Moog, Um Rio Imita o Reno. The space of this novel is marked by the existence of an imaginary city called Blumental, and the work itself brings aspects very representative of the culture of southern Brazil, marked by stereotypes and
customs originating in the traditions of immigrants who have lived in this region and their
descendants.Este artigo irá abordar o âmbito das questões de integração cultural do povo alemão na obra de autor brasileiro Vianna Moog, Um Rio Imita o Reno. O espaço do romance é marcado pela existência de uma cidade imaginária chamada Blumental, e o próprio trabalho traz aspectos muito representativas da cultura do sul do Brasil, marcados por estereótipos e costumes originários das tradições dos imigrantes que viveram nesta região e seus descendentes

Mixed forests reconsidered: A forest economics contribution on an ecological concept
No full textTo stimulate an economically oriented discussion on mixed forest management, this paper considers economic implications of mixed investments of pure stands of the Norway spruce (Picea abies (L.) Karst.) and the European beech (Fagus sylvatica L.) on a methodological basis. It is well known that the classical economic calculus leads to an overwhelming financial superiority of single species coniferous forest management in Central Europe, especially for growing monocultures of spruce. This explains why, since the early 19th century, the range of these forest types extends far beyond their natural limits. The change in the natural vegetation cover bore severe environmental problems as it was accompanied by a loss of biodiversity and a severe reduction in the resistance against storm, snow, ice, drought and insect damage of the forest stands. In contrast to this development as early as 1886, the Bavarian silviculturist Karl Gayer claimed that the forest condition must be able to deal with the uncertainty of future development. While pointing out that this condition could only be provided by “mixed forests” he, as a pioneer, formed an ecological concept for forest management. Unfortunately, forest managers have not broadly accepted his concept up to now. In order to support the ecological idea of “mixed forests”, it seems crucial to demonstrate that mixed diverse forests also possess economic advantages. Through using the portfolio theory founded by Markowitz and Sharpe, this paper evaluates mixed forest management and compares it to single species forest management. Its focus is on mixtures of Norway spruce and European beech. The Monte Carlo simulation method was used to simulate expected financial returns and their dispersion under risk. Mixed forests reduce the profitability but also show diversification effects due to only weak positive or even slightly negative correlated timber markets and diversified time structure of the timber harvests. Risk-averse decision-makers should therefore establish ecologically desired mixed forests with beech proportions between 10% and 50%, even if the profitability for mixed forests decreases. They will however benefit largely due to a significant risk attenuation. Although, effects of small-scale mixtures in stands comprising of many species were not considered we are sure that the findings of this study will in part also apply to mixtures on the forest stand level. While analysing an ecological concept from an economic viewpoint, which is transferable to the general idea of natural diversity, we intend to arouse interest in the ecologically oriented reader to evoke intensified future cooperation

No full textInterest rates in the German forest valuation literature of the early nineteenth century
No full textValuation with the help of the present value method can be traced back to at least medieval times. In forest literature the scientific achievement of calculating the present value of forestland is predominantly attributed to Martin Faustmann, whose 1849 publication is truly considered pioneering. However, without cheapening Faustmann's intellectual effort, this paper points to some earlier and relatively unknown German authors. By doing so, it presents the state of knowledge on forest valuation in the early nineteenth century, which is a very interesting and lively period of time with respect to the choice of the interest rate. It is revealed that already at that time publications on forest valuation showed a tendency towards an interest rate that yields a desired result
Entwicklung eines gemeinwohlorientierten Steuerungssystems für das kommunale Management
No full textÖkosystemfunktionen, Bürgerbegehren, Verpflichtungen der Daseinsvorsorge, Verantwortung für die Folgegenerationen und der Druck knapper Kassen führen in Kommunen zu Konflikten im Bemühen um zu steigerndes Gemeinwohl. Die Vielschichtigkeit öffentlicher Interessen, unterschiedliche Wirtschaftsformen städtischer Einrichtungen und kurzfristige politische Handlungszwänge erfordern ein hochflexibles, jedoch ganzheitliches Steuerungssystem für das kommunale Management. Ziel der Dissertation war deshalb eine strategische Balanced Scorecard als nachhaltiges Führungssystem zu entwickeln, mit zusätzlich besonderer Fokussierung auf Natur- und Umweltbelange. Durch den permanenten Abgleich, aber auch Beachtung der Korrelationen zwischen shareholder value und citizen value, ergeben sich kommunale Organisationsstrukturen, die den Anforderungen einer mündigen Gesellschaft und der wirtschaftlichen Notwendigkeiten gerecht werden.Ökosystemfunktionen, Bürgerbegehren, Verpflichtungen der Daseinsvorsorge, Verantwortung für die Folgegenerationen und der Druck knapper Kassen führen in Kommunen zu Konflikten im Bemühen um zu steigerndes Gemeinwohl.
