Methodology for identifying parameters for the TRNSYS model Type 210 -wood pellet stoves and boilers

This report describes a method how to perform measurements on boilers and stoves and how to identify parameters from the measurements for the boiler/stove-model TRNSYS Type 210. The model can be used for detailed annual system simulations using TRNSYS. Experience from measurements on three different pellet stoves and four boilers were used to develop this methodology. Recommendations for the set up of measurements are given and the re-quired combustion theory for the data evaluation and data preparation are given. The data evalua-tion showed that the uncertainties are quite large for the measured flue gas flow rate and for boilers and stoves with high fraction of energy going to the water jacket also the calculated heat rate to the room may have large uncertainties. A methodology for the parameter identification process and identified parameters for two different stoves and three boilers are given. Finally the identified models are compared with measured data showing that the model generally agreed well with meas-ured data during both stationary and dynamic conditions.

Dissonant Voices : Philosophy, Children's Literature, and Perfectionist Education

Dissonant Voices has a twofold aspiration. First, it is a philosophical treatment of everyday pedagogical interactions between children and their elders, between teachers and pupils. More specifically it is an exploration of the possibilities to go on with dissonant voices that interrupt established practices ��� our attunement ��� in behaviour, practice and thinking. Voices that are incomprehensible or expressions that are unacceptable, morally or otherwise. The text works on a tension between two inclinations: an inclination to wave off, discourage, or change an expression that is unacceptable or unintelligible; and an inclination to be tolerant and accept the dissonant expression as doing something worthwhile, but different. The second aspiration is a philosophical engagement with children���s literature. Reading children���s literature becomes a form of philosophising, a way to explore the complexity of a range of philosophical issues. This turn to literature marks a dissatisfaction with what philosophy can accomplish through argumentation and what philosophy can do with a particular and limited set of concepts for a subject, such as ethics. It is a way to go beyond philosophising as the founding of theories that justify particular responses. The philosophy of dissonance and children���s literature becomes a way to destabilise justifications of our established practices and ways of interacting. The philosophical investigations of dissonance are meant to make manifest the possibilities and risks of engaging in interactions beyond established agreement or attunements. Thinking of the dissonant voice as an expression beyond established practices calls for improvisation. Such improvisations become a perfectionist education where both the child and the elder, the teacher and the student, search for as yet unattained forms of interaction and take responsibility for every word and action of the interaction. The investigation goes through a number of picture books and novels for children such as Harry Potter, Garmann���s Summer, and books by Shaun Tan, Astrid Lindgren and Dr. Seuss as well narratives by J.R.R. Tolkien, Henrik Ibsen, Jane Austen and Henry David Thoreau. These works of fiction are read in conversation with philosophical works of, and inspired by, Ludwig Wittgenstein and Stanley Cavell, their moral perfectionism and ordinary language philosophy.

Perfectionist Philosophy as a (an Untaken) Way of Life

I am honored to respond to Paul Guyer���s elaboration on the role of examples of perfectionism in Cavell���s and Kant���s philosophies. Guyer���s appeal to Kant���s notion of freedom opens the way for suggestive readings of Cavell���s work on moral perfectionism but also, as I will show, for controversy. There are salient aspects of both Kant���s and Cavell���s philosophy that are crucial to understanding perfectionism and, let me call it, perfectionist education, that I wish to emphasize in response to Guyer. In responding to Guyer���s text, I shall do three things. First, I shall explain why I think it is misleading to speak of Cavell���s view that moral perfectionism is involved in a struggle to make oneself intelligible to oneself and others in terms of necessary and sufficient conditions for moral perfection. Rather, I will suggest that the constant work on oneself that is at the core of Cavell���s moral perfectionism is a constant work for intelligibility. Second, I shall recall a feature of Cavell���s perfectionism that Guyer does not explicitly speak of: the idea that perfectionism is a theme, ���outlook or dimension of thought embodied and developed in a set of texts.��� Or, as Cavell goes on to say, ���there is a place in mind where good books are in conversation. ��� [W]hat they often talk about ��� is how they can be, or sound, so much better than the people that compose them.��� This involves what I would call a perfectionist conception of the history of philosophy and the kinds of texts we take to belong to such history. Third, I shall sketch out how the struggle for intelligibility and a perfectionist view of engagement with texts and philosophy can lead to a view of philosophy as a form of education in itself. In concluding these three ���criticisms,��� I reach a position that I think is quite close to Guyer���s, but with a slightly shifted emphasis on what it means to read Kant and Cavell from a perfectionist point of view.

'In Charge of the Truffula Seeds' : On Children's Literature, Rationality and Children's Voices in Philosophy

In this paper I investigate how philosophy can speak for children and how children can have a voice in philosophy and speak for philosophy. I argue that we should understand children as responsible rational individuals who are involved in their own philosophical inquiries and who can be involved in our own philosophical investigations-not because of their rational abilities, but because we acknowledge them as conversational partners, acknowledge their reasons as reasons, and speak for them as well as let them speak for us and our rational community. In order to argue this I turn, first, to Gareth Matthews' philosophy of childhood and suggest a reconstruction of some of his concepts in line with the philosophy of Stanley Cavell. Second, in order to examine more closely our conceptions of rationality and our pictures of children, I consider the children's books, The Lorax and Where is My Sister? and Henrik Ibsen's play, The Wild Duck.

The Philosophy of Dissonant Children : Stanley Cavell's Wittgensteinian Philosophical Therapies as an Educational Conversation

Education is often understood as a process whereby children come to conform to the norms teachers believe should govern our practices. This picture problematically presumes that educators know in advance what it means for children to go on the way that is expected of them. In this essay Viktor Johansson suggests a revision of education, through the philosophy of Stanley Cavell, that can account for both the attunement in our practices and the possible dissonance that follows when the teacher and child do not go on together. There is an anxiety generated by the threat of disharmony in our educational undertakings that may drive teachers toward philosophy in educational contexts. Here Johansson offers a philosophical treatment of this intellectual anxiety that teachers may experience when they, upon meeting dissonant children, search for epistemic justifications of their practices���a treatment whereby dissonant children can support teachers in dissolving their intellectual frustrations.
