The inclination of the earth\u27s equatorial plane to the plane of the earth\u27s orbit around the sun, termed the obliquity of the ecliptic by astronomer\u27s, is approximately equal to 23º27\u27 of arc. If this inclination were 0º the sun would remain directly overhead the Equator throughout the year and there would be no seasons. In reality, the directly overhead point of the sun moves north and south with the seasons

Machine Issues Associated with Solid Freeform Fabrication

Before we begin a discussion of machine issues it is important that we categorize exactly what we mean. There are differences between the design of a research piece of equipment as compared to a commercial piece of equipment. A research piece of equipment has to have the flexibility to demonstrate a success pattern. A commercial piece of equipment, on the other hand, assumes that you have a stable platform and you are now trying to assess how broad a success path you have (Figure 1). In fact, you are trying to make that path as broad as possible so that the machine will not fail and will always work the same way. This particular talk, and my expertise, is much more along the lines of design of a research piece of equipment. What I will be talking about today are machine issues associated with developing a success path in Solid Freeform Fabrication. The machines we will be talking about have to have the flexibility to operate in a wide variety of ways with a wide variety of experiments.Mechanical Engineerin

Leapin\u27 Lizards -- L.O. Annie

Have you ever wondered about the credited quotes in Webster\u27s Third New International Dictionary? Webster\u27s assures us they are contemporary quotations from well-known people and publications. Close examination of the dictionary itself, however, reveals they are a bewildering diversity, not necessarily either contemporary or well-known

A focus on getting along: respect, caring and diversity

Drawing inspiration om Joseph T. O’Connell’s work on socio‐cultural integration, this pa‐ per connects the notion of ‘deep equality’ with two broad lessons that can be taken om O’Connell’s approach that pertain to the study of religious diversity in contemporary life. The rst is the recognition of the amorphous nature of religious identity, and the second is the necessity to search for models of socio‐cultural integration in the face of di erence. These lessons are valuable in providing an alternative discourse of diversity that moves away om problematisation to collaboration. Słowa kluczowe: ; ; ; ; ; ; ;;

Working memory and working attention: What could possibly evolve?

The concept of “working” memory is traceable back to nineteenth century theorists (Baldwin, 1894; James 1890) but the term itself was not used until the mid-twentieth century (Miller, Galanter & Pribram, 1960). A variety of different explanatory constructs have since evolved which all make use of the working memory label (Miyake & Shah, 1999). This history is briefly reviewed and alternative formulations of working memory (as language-processor, executive attention, and global workspace) are considered as potential mechanisms for cognitive change within and between individuals and between species. A means, derived from the literature on human problem-solving (Newell & Simon, 1972), of tracing memory and computational demands across a single task is described and applied to two specific examples of tool-use by chimpanzees and early hominids. The examples show how specific proposals for necessary and/or sufficient computational and memory requirements can be more rigorously assessed on a task by task basis. General difficulties in connecting cognitive theories (arising from the observed capabilities of individuals deprived of material support) with archaeological data (primarily remnants of material culture) are discussed

Application of Factorial Design in Selective Laser Sintering

Selective Laser Sintering (SLS) is a complex process involving many process parameters. These parameters are not all independent. A factorial design technique is utilized to study the effects of three main process parameters, laser power, laser beam scanning speed, and powder packing density as well as their interactions on the sintering depth and fractional density. The results of this investigation provide useful information for the further experimental analysis of the process parameters and for selecting suitable parameters for SLS process.Mechanical Engineerin
