Epistemicism and modality

AbstractWhat kind of semantics should someone who accepts the epistemicist theory of vagueness defended in Timothy Williamson's Vagueness (1994) give a definiteness operator? To impose some interesting constraints on acceptable answers to this question, I will assume that the object language also contains a metaphysical necessity operator and a metaphysical actuality operator. I will suggest that the answer is to be found by working within a three-dimensional model theory. I will provide sketches of two ways of extracting an epistemicist semantics from that model theory, one of which I will find to be more plausible than the other.

Compressor Design

Profile is the most important base in double-action compressor design. Different cylinder profile decides different working chamber volume in double-action sliding vane compressor. Five equations of cylinder profile were researched by calculating the working chamber volumes and a new cylinder profile equation of double-action sliding vane compressor was composed to get larger chamber. In same condition with the other equations, the working chamber volume of new profile is bigger than the old profiles over 20 percent while it has no change in the moving and friction characters. And a three dimensional model based on SolidWorks of a new profile was done. Finally, it was assembled successfully in computer to check the design.

Process Based Models

Ice-sheet responses to climate warming and associated sea-level rise depend sensitively on the form of the slip law that relates drag at the beds of glaciers to their slip velocity and basal water pressure. Process-based models of glacier slip over idealized, hard (rigid) beds with water-filled cavities yield slip laws in which drag decreases with increasing slip velocity or water pressure (rate-weakening drag). We present results of a process-based, three-dimensional model of glacier slip applied to measured bed topographies. We find that consideration of actual glacier beds eliminates or makes insignificant rate-weakening drag, thereby uniting process-based models of slip with some ice-sheet model parameterizations. Computed slip laws have the same form as those indicated by experiments with ice dragged over deformable till, the other common bed condition. Thus, these results may point to a universal slip law that would simplify and improve estimations of glacier discharges to the oceans.

Presenting the results of a qualitative research on the practice of prayer in pastoral care, this article discusses the questions which most interest ministers in the Protestant Church in the Netherlands. Dialogue − between the pastor and the other, and between the conversation partners and God − is a key issue. The article presents a three-dimensional model of this dialogue and elaborates a theology of pastoral prayer as spiritual fellowship. It then argues that in pastoral care, ministers, with their conversation partners, should pay more attention to the theological quality and the practical significance of dialogue on praying together.

The aim of this paper is to present an overview of studies for the representation/visualization of stakeholders with a proposal of our own method of visualization. The following text examines the existing representational methods and at the same time critically evaluates their advantages and disadvantages. In addition, our own proposed approach is also presented.The need to develop visualization methods for use in the concept of stakeholders has been accepted by researchers, and it is possible to encounter number of various alternatives which have been applied more or less successfully. The shared weakness of the majority of the models is that they only represent two main attributes simultaneously. When such models do contain three variables, then the third one is only a complementary aspect of the relationship compared to the two dominant attributes.Our proposed visualisation model based on three Mitchell´s (1997) stakeholder attributes should overcome the before mentioned disadvantage. Also, it takes into account the development over time in accordance with the dynamic of the relationships with the stakeholders. Therefore, the proposed three-dimensional model meets these needs and simultaneously removes the shortcomings of the other models, which are identified in our overview presented in this paper.

The Finite Element Model

In this paper, a mechanical MEMS S&A device has been proposed. The size of the device is 10mm×13mm×0.5mm. The role of the lock-releasing mechanism is to amplify the moving distance of two times, so as to effectively guarantee the time of long-distance arming. Through establishing the three-dimensional model of without optimized lock-releasing mechanism, establishing the force and the parameters of locking-releasing mechanism, deriving the mathematical model according to the rigid dynamic mechanics theory and establishing the finite element model by using ANSYS/LS-DYNA, appropriate lock-releasing mechanism is designed to meet two items, one item is that the lock-releasing rod locks the main centrifugal slider before sub-centrifugal slider movement in place; the other item is that sub-centrifugal slider will hit the lock-releasing rod when it movement in place, so the lock-releasing rod rotates around rotational positioning block and releases the main centrifugal slider.
