Comminution 1994 Proceedings of the 8th European Symposium on Comminution and 50th Event of the European Federation of Chemical Engineering, May 17-19, 1994 Stockholm, Swede - PDF
نویسندگان: خلاصه: Particle arrangements and confinements can be classified in the four groups (1) single particle situation, (2) one-particle layer, (3) particle bed confined closely or widely, and (4) ideal particle bed. Any confinement influences the stress distribution inside the bed due to the wall friction, and a complex stress field arises. The size-reduction effect is represented with the fraction of broken particles, the breakage function and the specific surface increases. The breakage functions of the particle bed comminution display as truncated logarithmic normal distributions. The stressing intensity can be quantified by the pressure, the stress field characteristics or the energy absorption. Although the stress field situation can differ extremely, the overall energy absorption has been proven to represent the stressing intensity very well in respect to the size-reduction. The transition from a close to a moderately wide confinement does not affect the size-reduction strongly. Steel balls inserted in a particle bed improve the breakage of coarse particles at a low intensity level. This advantage fades with increasing intensity and decreasing particle size.
Construction Management JumpStart The Best First Step Toward a Career in Construction Management (3rd Edition) - Original PDF
نویسندگان: خلاصه: Introduction Congratulations! You are about to embark on an adventure. This book is about the processes, the people, and the practices that we call construction management—a term and a profession that may be unfamiliar to many people. Construction, as most individuals understand it, is an activity or a series of activities that involves some craftspeople, building materials, tools, and equip- ment. But you will learn that there is a great deal more to it than that. If you think that construction is all about brawn and not much about brains, then you probably haven’t been paying very close attention to what has been going on in the built environment in the past several decades. Buildings today can be very complicated, and the building process has become extremely demanding. It takes savvy professional talent to orchestrate all of the means and methods needed to accomplish the building challenge. This book’s focus is not on construction per se. Its focus is on the construction process and those individuals who manage that process. Construction manage- ment involves the organization, coordination, and strategic effort applied to the construction activities and the numerous resources needed to achieve the building objective. Construction management combines both the art and science of building technology along with the essential principles of business, management, computer technology, and leadership. Construction management as a profession is a relatively new concept, which may explain why you have not heard of it before. Up until the 1960s, the management tasks associated with large construction projects were typically handled by civil engineers. But in 1965, faculty from nine universities gathered in Florida to form the Associated Schools of Construction. What started as a movement to upgrade the status of construction education at universities evolved into a standardized construction management curriculum leading to an exciting new career choice, one for which there was increasing demand. Men and women who love the idea of transforming a lifeless set of plans and specifications into something real—a single-family home, a high-rise office building, a biotech facility, a super highway, or a magnificent suspension bridge—had found an educational program that provided both the academic course work and the practical management tools needed to plan, organize, and coordinate the increas- ingly complex construction process. If you are one of the many individuals who desire the intellectual challenges of architecture, engineering, technology, and business, yet long to be outside in the thick of things, getting your hands dirty and ultimately producing a tangible result—something of lasting value—then construction management might just be the ticket for you
Discrete Element Modelling of Particulate Media by Chuan-Yu Wu - Original PDF
نویسندگان: خلاصه: In numerical simulations of dense two-phase flow involving particulate materials the Discrete Element Method (DEM) has proved particularly effective in capturing the complex hydrodynamics of the solid phase. 1 DEM-based granular solid dynamics, including collisions and persistent contact with elaborate force-displacement laws, friction and cohesion have shown to be superior to traditional fluid-like, continuum approaches, which typically require coarse approximations and the introduction of artificial variables like solids pressure and viscosity. However, computational limitations of DEM models do not allow adding also the burden of flow simulations resolved at the level of particle-particle interstices, so that typically an averaged scale approach, with computational cell sizes of the order of a few particle diameters, is used. 2 .3 As a consequence, formulations of the drag force acting on individual particles are required to close the set of equations to solve for the solid and fluid phases. While many drag force models for monodisperse systems have been proposed in the literature, as discussed below, expressions for such force on a particle in a multi-particle system is currently the subject of extensive research work
Epistemology Modalized by Kelly Becker - Original PDF
نویسندگان: خلاصه: 1 Introduction: Externalism and modalism Recent developments in epistemology, and in philosophy more generally, provide a promising foundation for an answer to a very old question: What is knowledge? The question stymied Plato in the Theaetetus, from which the traditional tripartite analysis of knowledge as justified true belief derives. It received fresh attention when Edmund Gettier showed that the three conditions of the traditional analysis were not jointly sufficient for knowledge. Subsequent attempts to repair the analysis of knowledge aimed (1) to amend the notion of justification to avoid the Gettier problem; (2) to add a fourth condition, for instance that there are no defeaters to one’s justification; or (3) to replace justification with some other condition that captures the requisite link between belief and truth constitutive of knowledge. 1 The uniqueness of the third strategy is not clearly defined because one could easily argue that, whatever the necessary link between belief and truth turns out to be, it just is justification. Nonetheless, I see myself as pursuing this approach because the very term ‘‘justification’’ is all too pregnant with associated notions that I believe are not essential to knowledge, and work- ing toward an account that explicitly involves justification as a necessary condition can lead us away from a proper understanding of knowledge. (A specific instance of this problem arises in Chapter 2.) Unencumbered by the requirement to explicate ‘‘justification,’’ we can inquire into the requisite belief-truth link constitutive of knowledge by testing proposals for that link against our intuitions concerning whether an agent actually knows in parti- cular cases. If we find that a correct or, at least, working account of that link does not capture the traditional conception of justification, then so be it. 2 Our topic, then, is propositional knowledge: knowledge that p for some arbitrary proposition p. I will not claim that all other forms of knowledge, for instance, knowledge by acquaintance, knowledge of one’s own phenom- enological states, and know-how, are reducible to propositional knowledge, and so do not intend to give an account of knowledge in general. This only slightly diminishes the importance of an account of propositional knowl- edge, since it is through sentences and the propositions they express that we think and talk about the world. It would be a significant advance in our understanding if we had a plausible theory of such knowledge
Evolution 2.0: Breaking the Deadlock Between Darwin and Design - Epub + Converted PDF
نویسندگان: خلاصه: This product is estimated to be delivered within 2-3 weeks from the dispatch date. In the ongoing debate about evolution, science and faith face off. But the truth is both sides are right and wrong. In one corner: Atheists like Richard Dawkins, Daniel Dennett, and Jerry Coyne. They insist evolution happens by blind random accident. Their devout adherence to Neo-Darwinism omits the latest science, glossing over crucial questions and fascinating details. In the other corner: Intelligent Design advocates like William Dembski, Stephen Meyer, and Michael Behe. Many defy scientific consensus, maintaining that evolution is a fraud and rejecting common ancestry outright. There is a third way. Evolution 2.0 proves that, while evolution is not a hoax, neither is it random nor accidental. Changes are targeted, adaptive, and aware. You’ll discover: How organisms re-engineer their genetic destiny in real time Amazing systems living things use to re-design themselves Every cell is armed with machinery for editing its own DNA The five amazing tools organisms use to alter their genetics 70 years of scientific discoveries-of which the public has heard virtually nothing! Perry Marshall approached evolution with skepticism for religious reasons. As an engineer, he rejected the concept of organisms randomly evolving. But an epiphany-that DNA is code, much like data in our digital age-sparked a 10-year journey of in-depth research into more than 70 years of under-reported evolutionary science. This led to a new understanding of evolution-an evolution 2.0 that not only furthers technology and medicine, but fuels our sense of wonder at life itself. This book will open your eyes and transform your thinking about evolution and God. You’ll gain a deeper appreciation for our place in the universe. You’ll see the world around you as you’ve never seen it before. Evolution 2.0 pinpoints the central mystery of biology, offering a multimillion dollar technology prize at naturalcode.org to the first person who can solve it.
Experimental Design in Psychology Ninth Edition A Case Approach - Original PDF
نویسندگان: خلاصه: PART I Basic Principles in Experimental Design Some people dread taking the research methods course required for most psychology majors. I’m not sure of all the reasons why, but for many they fear the course. It often has a lab compo- nent; at some universities it is worth more credit than regular content courses. It simply often has the reputation of being “hard.” Instead, for a moment, consider that research methods is exciting! It provides you the tools to be able to conduct your own research. Finally, you are in charge and you can study what you want to know. You are explorer, scientist, puzzle solver. The frst half of this book (Part I) introduces to you the basics of scientifc inquiry, including what science is and how psychological science is a subset of it. We’ll discuss how to distinguish between facts, theories, and speculation and how each are useful for developing research questions. We’ll cover the basics of the scientifc method, the specifcs of experimental design, and a review of other non-experimental research methods (so you know when it is appropriate to choose the experiment). You will be given insight into how to fnd and read the literature in psychology as well as how to plan, design, and carry out research. We will also cover the rules and procedures designed to ensure sound, ethical, and meaningful research. Throughout this material, you’ll be exposed to examples from the psychological literature that will allow you to see concepts and principles as they play out in real research studies. And in one particu- lar chapter (Chapter 7) you’ll be prompted to critically analyze experimental designs that have conceptual or technical faws. Being sensitive to mistakes will help you avoid them yourself
Exporting the European Convention on Human Rights - Original PDF
نویسندگان: خلاصه: As for the right to protect one’s private and family life, as enshrined in Article 8 ECHR, the CJEU provided the very first explicit reference to the ECHR in Rutili v Minister for the Interior�53 In casu, the Convention was conceived as a source of inspiration as well as a human rights standard for determining the legality and legitimacy of the acts of Member States applying EU law. Therefore, the CJEU applied the ECHR as a clear human rights standard to also interpret the ‘public policy’ exception to the free movement of workers, justifying Member States to restrict this freedom only to the extent authorised by the ECHR, that is, when it is necessary for the protection of the interests of national security or public safety ‘in a democratic society’.54 This landmark case illustrates how the CJEU has progres- sively shaped its autonomous human rights case law, inspired, though, by the ECHR and by the common constitutional traditions of EU Member States.55 The Luxembourg Court established a much broader human rights review over their actions and paved the way for a much clearer reference to the Convention’s provi- sions as a material source of EU legal order, rather than a source of inspiration.56 Nonetheless, besides the consensus in this field, conflicts and inconsistencies between the two European jurisdictions have not been sidestepped. The main preoccupation of the following section is thus to unveil the extent to which the CJEU has directly referred to ECHR norms to protect private and family life57 with regard to the most controversial fields of data protection and migration/ asylum cases.
From Darwin to Derrida Selfish Genes, Social Selves, and the Meanings of Life - Epub + Converted PDF
نویسندگان: خلاصه: Evolutionary theory can be a nasty business. Perhaps it has something to say about human nature. Most scientifically respectable evolutionary theories wear garments of math. I think of mathematical models as disciplined metaphors. We use x to represent something in the world, say slugs, and y to represent something else, say lettuces, then we analyze the relation of x to y using mathematics. We imagine that slugs and lettuces behave like x and y in the model, and then we use how x and y behave in the model to understand how slugs and lettuces behave in the world. Nobody can argue with mathematical models—that is one of the points of using mathematics—but there can be endless arguments about what you put into a model and what you leave out, and endless arguments about what the model means, because metaphors can be interpreted in many ways. I am not criticizing the use of metaphors—far from it, they are essential. All that we know about the world is metaphor. Our perceptions are a virtual reality, not the thing in itself but something that stands in the place of the thing. Phenomena are metaphors used to comprehend things. Don’t worry, this book contains almost no mathematics; but, if you don’t like metaphor, then this is probably a good time to return the book and ask for a refund.
Game storming by Dave Gray Sunni Brown James Macanufo - Epub + Converted PDF
نویسندگان: خلاصه: Imagine a boy playing with a ball. He kicks the ball against a wall, and the ball bounces back to him. He stops the ball with his foot and kicks it again. By engaging in this kind of play, the boy learns to associate certain movements of his body with the movements of the ball in space. We could call this associative play. Now imagine that the boy is waiting for a friend. The friend appears, and the two boys begin to walk down a sidewalk together, kicking the ball back and forth as they go. Now the play has gained a social dimension; one boy's actions suggest a response, and vice versa. You could think of this form of play as a kind of improvised conversation, where the two boys engage each other using the ball as a medium. This kind of play has no clear beginning or end; rather, it flows seamlessly from one state into another. We could call this streaming play. Now imagine that the boys come to a small park, and that they become bored simply kicking the ball back and forth. One boy says to the other, "Let's take turns trying to hit that tree. You have to kick the ball from behind this line." The boy draws a line by dragging his heel through the dirt. "We'll take turns kicking the ball. Each time you hit the tree you get a point. First one to five wins." The other boy agrees and they begin to play. Now the play has become a game; a fundamentally different kind of play. What makes a game different? We can break down this very simple game into some basic components that separate it from other kinds of play.Imagine a boy playing with a ball.
