Relevant Cost

The following article completes the review of the development and state of engineering economic applications of the Second Law of Thermodynamics, which was begun in Part I (El-Sayed and Gaggioli, 1989). We began with a historical review, followed by a brief discussion of the relevant cost accounting concepts and, in turn, general descriptions of the different exergy costing methods which are in existence. Then, the various algebraic techniques of exergy costing were analyzed and critiqued, generally by considering successive publications developing and/or based on a technique. This paper, on the other hand, is devoted primarily to calculus methods. Of course the algebraic and calculus techniques do relate to each other, and those relationships are developed here. Furthermore, general concepts, discussion and conclusions which are relevant to both algebraic and calculus methods are presented, along with suggestions regarding further research.

Analyse Time

This article borrows its methodology from physics in order to analyse time in the theatre as evolution of order. Two set designs (both designed by Roni Toren for the Khan Theatre in Jerusalem) are portrayed through this perspective, representing inverse examples. In Measure for Measure, directed by Gadi Roll, the temporal evolution of space is from order to disorder, obeying the second law of thermodynamics. On the other hand, in The Seagull, directed by Ofira Henig, the evolution contradicts that law. The problem of depicting disorder on stage, the possibility of such a contradiction, the implication of the two different perceptions and their ethical values are discussed to prove the effectiveness of a methodology adopted from physics.

Ultimate Objective

The following report reviews the development and state of engineering economic applications of the second law of thermodynamics. It encompasses virtually all of the work carried out publicly in the United States, and to the best of our knowledge that done in other countries (but also see Tsatsaronis, 1987). The ultimate objective here is to provide direction for future research on the fundamentals and applications of this subject, and for the support thereof. We begin with a historical review, which is important for better comprehension of second law costing, its objectives, its state, and its prospects. Following the history, further relevant background, on cost accounting, is presented in Part II. Part III describes in general terms the different exergy costing methods which are in existence. Parts IV and V constitute the nucleus of the report. Therein the various techniques are analyzed and critiqued, generally by considering successive publications developing and/or based on a technique. Part IV is devoted to algebraic methods for determining and applying exergy costs and Part V, to be presented in the sequel to this article, to calculus methods. These two parts do refer to each other, and the relationships between them are developed. Suggestions regarding further research are incorporated into both sections. It should be mentioned that the references we cite are not intended to be exhaustive. However, it is our intention to refer to the most recent work of each author, so that the reader may trace back to earlier publications. Also, the bibliographies of Wepfer (1979) and Liu and Wepfer (1983) are quite exhaustive.

The Belief-Desire-Intention (BDI) model is a popular approach to design flexible agents. The key ingredient of BDI model, that contributed to concretize behavioral flexibility, is the inclusion of the practical reasoning. On the other hand, researchers signaled some missing flexibility’s ingredient, in BDI model, essentially the lack of learning. Therefore, an extensive research was conducted in order to extend BDI agents with learning. Although this latter body of research is important, the key contribution of BDI model, i.e., practical reasoning, did not receive a sufficient attention. For instance, for performance reasons, some of the concepts included in the BDI model are neglected by BDI architectures. Neglecting these concepts was criticized by some researchers, as the ability of the agent to reason will be limited, which eventually leads to a more or less flexible reasoning, depending on the concepts explicitly included. The current paper aims to stimulate the researchers to re-explore the concretization of practical reasoning in BDI architectures. Concretely, this paper aims to stimulate a critical review of BDI architectures regarding the flexibility, inherent from the practical reasoning, in the context of single agents, situated in an environment which is not associated with uncertainty. Based on this review, we sketch a new orientation and some suggested improvements for the design of BDI agents. Finally, a simple experiment on a specific case study is carried out to evaluate some suggested improvements, namely the contribution of the agent’s “well-informedness” in the enhancement of the behavioral flexibility.

Syntactic Relations

The paper is part of a series of publications that set out to examine various aspects in the analysis of appositive constructions. The purpose of this particular study is to reveal the multidimensional, diverse, and complex interaction between three types of syntactic relations – attributive, predicative, and appositive. The study offers a critical review of various theories on the status of the grammatical relation between the components of non-detached (close) appositive constructions. The main argument of this paper is that determining this status, on the one hand, is a function of the morphological and semantic characteristics of the components of the construction, while, on the other hand, it determines their syntactic status.

Rosemberg (1991) has made a critical review of a long-standing discussion between Eastern philologists and Buddhist philosophers. The discussion is centered around the translation of the doctrine on the one hand, and its philosophical systematization on the other hand. When scientific-philological translation prevails, the literal meaning of Buddhist terminology is declared to be its basis. The young scholar, who had specialized in Japan, studied Buddhism from Japanese and Chinese sources and collected lexicographic material from non-Hindu sources. After comparing them, he encountered inaccuracies in the translation. In an attempt to overcome them, he preferred the point of view of the philosophy of Buddhism. The conclusion that he has drawn in the preface of this edition is that the study should begin with a systematization of antiquity.

Ethics And Politics

In first chapters of this article MacIntyre?s view of ethics is analyzed, together with his critics of liberalism as philosophical and political theory, as well as dominant ideological conception. In last chapters MacIntyre?s view of the relation between politics and ethics is considered, along with the critical review of his theoretical positions. Macintyre?s conception is regarded on the one hand as very broad, because the entire morality is identified with ethical life, while on the other hand it is regarded as too narrow since it excludes certain essential aspects of deliberation which refers to the sphere of individual rights, the relations between communities, as well as distribution of goods within the state.

Chemical Reaction Mechanisms

In 1997, Ross Kelly and his coworkers at Boston College reported their results from an experiment with an intriguing premise (Kelly et al., 1997; see also Kelly et al., 1998). They had synthesized the molecule shown in figure 12.1. It was designed to be a “molecular ratchet,” so named because it appeared that it should undergo internal rotation about the A—B bond more readily in one direction than the other. The reason for thinking this might occur was that the benzophenanthrene moiety—the “pawl” of the ratchet—was anticipated to be helical. Thus, in some sense, this might be an inverse ratchet where the asymmetry dictating the sense of rotation would reside in the pawl rather than in the “teeth” on the “wheel” (the triptycene unit) as it does in a normal mechanical ratchet. Kelly and coworkers designed an elegant experiment to determine whether their molecular ratchet was functioning as anticipated, and they were (presumably) disappointed to find that it was not—internal rotation about the A—B bond occurred at equal rates in each direction. In 1998 Davis pointed out that occurrence of the desired behavior of the molecular ratchet would have constituted a violation of the second law of thermodynamics (Davis, 1998). With hindsight, I think most chemists would agree that Davis’s critique is unassailable, although the appeal of the mechanical analogy was so strong that I imagine those same chemists would also understand if Kelly et al. had overlooked the thermodynamic consequences of their proposal in the original design of the experiment. But now comes the interesting question: Suppose Kelly et al. had been fully aware that their experiment, if successful, would undermine the second law of thermodynamics, should they have conducted it anyway? Davis, in his critique writes: . . .Some would argue that this experiment was misconceived. To challenge the Second Law may be seen as scientific heresy (a nice irony, considering the Jesuit origins of Boston College), and the theoretical arguments against molecular ratchets and trapdoors are well developed. . . .

This chapter discusses the well-known dichotomies between sentence negation and constituent negation on the one hand and external negation and internal negation on the other hand. It explains how the notions differ and where they show overlap. Crucial in this discussion is the presentation and critical review of some of the most relevant tests for negation as discussed by Klima (1964). The discussion leads to the observation that both sentence negation and constituent negation are umbrella terms for multiple scopal types of negation. The chapter further shows how a careful analysis of negative morphology can be insightful in putting up a more fine-grained classification that does better justice to the reality of negative markers than captured by the well-known dichotomies.

The problem of the mixing of two streams of the same compressible fluid in a constant-area duct is solved by applying certain dimensionless parameters first used by Kiselev. The extension to dissimilar fluids or to more than two streams is straightforward. Although the analysis is unrestricted, detailed results are given only for the case where one stream is sonic or supersonic and the other sonic or subsonic at the origin of mixing. For this case, the second law of thermodynamics indicates that, of the two solutions of the conservation equations, the subsonic one is always permitted while some of the supersonic solutions are thermodynamically impossible. Upon examination of experimental data, it is further concluded that of the admissible supersonic solutions, only one may be expected to occur. The establishment of this supersonic solution with its relatively high stagnation pressure leads to the conclusion that when the initial temperatures are sufficiently different, there exist thermodynamically possible solutions with a stagnation pressure higher than that of either of the two initial streams.

The hypothetical possibility of distinguishing preparations described by non-orthogonal density matrices does not necessarily imply a violation of the second law of thermodynamics, as was instead stated by von Neumann. On the other hand, such a possibility would surely mean that the particular density-matrix space (and related Hilbert space) adopted would not be adequate to describe the hypothetical new experimental facts. These points are shown by making clear the distinction between physical preparations and the density matrices which represent them, and then comparing a "quantum" thermodynamic analysis given by Peres with a "classical" one given by Jaynes.
