The purpose of this paper is to present a very general overview as to how basic concepts of aerodynamics and hydrodynamics can be utilized in the selection and trim of sails. I have used the term selection to go all the way back to the routes of designing and selecting a rig for a given boat. The paper introduces absolutely no data and, in fact, does not explore any existing data in detail. Its main purpose is to show that almost any decision on rig or sails on a sail boat is always a compromise of varying forces. Sometimes these compromises are conflicting dynamics of the hull and sails, other times the forces are man-made such as rule parameters. Perhaps I could have done a more scien­tific job by choosing just one set of parameters that are in conflict and explored these in great detail showing how a conclusion can be reached from all the varying inputs into one particular problem involving rig, sails or hull. This type of thorough analysis, which would obviously require more exacting research to prove the hypothesis once defined, is not my strength. Therefore, it would be inappropriate for me to do such an analysis. My strength is in actually applying a large range of sail­ing theory to actual on-the-water sailing conditions. What I hope to accomplish by this paper is to let sailors realize that when making a decision on a rig, a particu­lar sail, or how to trim a particular sail, they first must decide what they want to accomplish with the rig, sail or sail trim. They must think about it in general terms as to what direction they should take aerodynamically or hydrodynamically to get the forces they want to achieve. Then they must go about the task with the full realization that there is no preset answer and that they must be willing to experiment in order to hone in on the optimum. The input variables of the hydrodynamics of a pitching yacht going to weather in a moderate breeze that is constantly receding and increasing in velocity as well as direction defies simple solu­tions. Thus, the best compromise is usually the best solution.

Because the term θεóς is used so infrequently of Jesus in the New Testament, it is not surprising to find that there are relatively few discussions of it as a christological title. However, it may be of value to investigate the way in which the Fourth Gospel speaks of Jesus as ‘God’ since its usage differs somewhat from that of the rest of the New Testament. First, the extent to which the New Testament describes Jesus as God will be surveyed, and this will be contrasted in general terms with the approach of the Fourth Evangelist. Then the passages in the Fourth Gospel which may call Jesus ‘God’ will be examined in more detail, and an attempt will be made to establish the way in which this designation is used by the evangelist. Next it will be asked how the distinctive usage of the Fourth Gospel came to be adopted. Finally the view that the word θεóς expresses a functional christology will be considered.

The purpose of the research is to outline the structure of the main methodological ideas within the frames of interpretive thinking in the essay of the famous Vistnyk’s writer, critic and essayist Yevhen Malaniuk. Considering the purpose and tasks of the studio, an interdisciplinary methodological base, related to the author’s “national approach”, has been worked out. The epistemological potential of national philosophy as a philosophy of national existence, national science as a theory of nation, hermeneutics as a theory and practice of interpretation and post-colonialism as interpretation of cultural phenomena from the standpoint of anti- and post-imperial consciousness are used in the work. The scientific novelty is that on the basis of the previous hermeneutic generalization and definition of national-existential methodology, a propaedeutic outlining of the structure of national-philosophical concepts within the frames of the essayistic interpretation of reality in Ye. Malaniuk is proposed. In the methodological sense, the writer’s essayism is structured by such concepts as nation-centrism, idealism, voluntarism, heroism, and can be considered as one of the variants (close by the experiences of D. Dontsov, Yu. Lypa, M. Mukhyn, etc.) of the Vistnyk’s national-philosophical (national-existential, nationalistic or nation-centric) hermeneutics, that is, the way of understanding, which the author by himself outlined as a “national approach”. The support of Ye. Malaniuk as a culture-philosopher and exegete on the eternal nation-centric values and criteria in his essayistic studies makes his reflections not only historically interesting, but also theoretically productive, classically important for the development of modern Ukrainian hermeneutics and humanities in general.

I. While so much improvement has recently taken place in the arrangement and construction of various tables for facilitating calculations founded on existing data, very little has been done in the way of investigating and correcting the data themselves; and it is feared that the question of the rate of mortality among select lives is still involved in the greatest doubt and obscurity.II. It is not proposed in the present paper to go farther than to show that the rate of mortality, during the first year of selection, of select assured lives is so materially different from what it has hitherto been represented, as to lead to the inference that the data from which the erroneous deduction has been made cannot be true data for the ascertainment of the value of selection. To investigate the rate of mortality of select lives at separate ages, I conceive to be of the utmost importance for the elucidation of truth, and the proper direction of sanatory inquiries; but I do not consider that sufficient data at present exist for the determination of this, and these can only be obtained by a united inquiry. I shall be very happy if the present observations have any effect in hastening such an investigation, which sooner or later must be entered upon.

Software-defined networking is changing the way we design and manage networks. This prominent paradigm based on the separation of control and management plane is highly heterogeneous with different devices from various technologies and leads to an incredible growing of materials. As SDN expands in size of devices and complexity, it faces greater administrative and management challenges. The paradigm of MDA was introduced using NETCONF/YANG as a way to model in order to deal with these management challenges and soften the development of SDN applications. The researchers joined the MDA and its related concepts as model-driven engineering to SDN to implement a platform called model-driven networking increasing the level of abstraction on development. This chapter presents a comprehensive survey of the research relating to MDN paradigm. It starts by introducing the basic concepts of SDN. Next, it presents the concepts related to MDA, and the YANG which is a modeling language. Last, it highlights the studies introducing the MDN paradigm and its benefits in SDN applications.

Authentication is the way of identifying an individual. The techniques used to accomplish such practice strongly depend on the involved parties, their interconnection, and the required level of security. In all cases, authentication is used to enforce property protection, and may be specifically intended for the copyright protection of digital contents published on the Internet. This chapter introduces the basic concepts of authentication, explaining their relationship with property protection. The basic functionalities of challenge-response frameworks are presented, together with several applications and the future trends.

The way that herpetologists have traditionally measuredlive snakes is by stretching them on a ruler andrecording the total length (TL). However, due to the thinconstitution of the snake, the large number of intervertebraljoints, and slim muscular mass of most snakes,it is easier to stretch a snake than it is to stretch anyother vertebrate. The result of this is that the length ofa snake recorded is infl uenced by how much the animalis stretched. Stretching it as much as possible is perhapsa precise way to measure the length of the specimenbut it might not correspond to the actual length ofa live animal. Furthermore, it may seriously injure a livesnake. Another method involves placing the snake in aclear plexiglass box and pressing it with a soft materialsuch as rubber foam against a clear surface. Measuringthe length of the snake may be done by outlining itsbody with a string (Fitch 1987; Frye 1991). However, thismethod is restricted to small animals that can be placedin a box, and in addition, no indications of accuracy of thetechnique are given. Measuring the snakes with a fl exibletape has also been reported (Blouin-Demers 2003)but when dealing with a large animals the way the tapeis positioned can produce great variance on the fi nal outcome.In this contribution we revise alternative ways tomeasuring a snake and propose a method that offers repeatableresults. We further analyze the precision of thismethod by using a sample of measurements taken fromwild populations of green anacondas (Eunectes murinus)with a large range of sizes.

The pendulum has swung; in this case, it may be a double pendulum. The double pendulum is a pendulum hanging from a pendulum. It is a simple physical system used in physics to demonstrate mathematical chaos. When the motion of its tip is monitored, it appears very predictable at the outset, but soon reveals a very chaotic and unpredictable pattern. It is very difficult to know where the tip of the double pendulum will be at any given time in the future. This seems to describe the course of the use of opioids, especially for the treatment of chronic pain. Once, all but ignored, then heralded, and then demonized. At every step of the way, pundits will argue the incompleteness, absence, or misinterpretation of existing data. It is important to understand the psychological environment is which the opioid tapering movement occurs and to carefully consider the process in the context of the individual patient. Simply instituting another set of presumptive evidence-based guidelines could have unforeseen, and potentially tragic, consequences for the patient.

Notwithstanding its overwhelming descriptive power for existing data, it is not clear whether the kinematic theory of Plamondon & Alimi could generate new insights into biomechanical constraints and psychological processes underlying the way organisms trade off speed for accuracy. The kinematic model should elaborate on the role of neuromotor noise and on biomechanical strategies for reducing endpoint variability related to such noise.

Like Professor Manser (January 1983) I felt moved to comment on D. Z. Phillips's article on Sartre (‘Bad Faith and Sartre's Waiter’ (January 1981)); and the editor thoughtfully suggested that we should exchange our comments. We both agree, I think, that Phillips's concern over Sartre's alleged unfairness to waiters has led him to be unfair to Sartre, but whereas Manser is concerned to pursue in general terms the questions of sincerity and commitment I am more concerned to see the example, and the implications that Sartre draws from it, as showing the kind of writer he was and the view of the world that he held. It is this context that seems to me to be lacking in Phillips's article. He thinks that Sartre is unfair to waiters by over-simplifying their attitudes to their jobs, the ways in which they behave when doing them, and the satisfaction that they derive from them. He draws out of these specific comments some more general criticisms of the way in which Sartre over-simplifies the problems of choice: how much of our total personality we express in any particular choice that we make; and the degree of commitment that individual choices involve. All this is very reasonable, but he does not really get to grips with Sartre's concern.
