چکیده
The objective of this paper is to develop criteria that guarantee that a nite group G which acts faithfully on a vector space V possesses \many" orbits of diierent sizes. This has consequences on (classical and modular) character degrees of nite solvable groups.

Reading with fixed and variable character pitch.
We compared the effects of fixed and variable (proportional) spacing on reading speeds and found variable pitch to yield better performance at medium and large character sizes and fixed pitch to be superior for character sizes approaching the acuity limit. The data indicate at least two crowding effects at the smallest sizes: one that interferes with individual character identification and one ...
متن کاملRetrieving Information about a Group from Its Character Degrees or from Its Class Sizes
We prove that a knowledge of the character degrees of a finite group G and of their multiplicities determines whether G has a Sylow p-subgroup as a direct factor. An analogous result based on a knowledge of the conjugacy class sizes was known. We prove variations of both results and discuss their similarities.
متن کاملPositive Display Polarity Is Particularly Advantageous for Small Character Sizes: Implications for Display Design
OBJECTIVE To test the display luminance hypothesis of the positive polarity advantage and gain insights for display design, the joint effects of display polarity and character size were assessed with a proofreading task BACKGROUND Studies have shown that dark characters on light background (positive polarity) lead to better legibility than do light characters on dark background (negative pola...
متن کاملLBG Vector Quantization for Recognition of Handwritten Marathi Barakhadi
Handwritten character recognition has been studied a lot in the past and involves various problems due to many reasons. In this paper, novel method of Handwritten Marathi Barakhadi Character Recognition with Shape and Texture features has been proposed. The Shape features and Texture feature are more unique, so a novel technique based on combination of these is derived and proposed here. For ex...
متن کاملEvaluation of Possible Reproductively Mediated Character Displacement in the Crayfishes, Orconectes rusticus and O. sanbornii
Orconectes rusticus is replacing several species of crayfishes in north-central and northeastern North America, including 0. sanbornii in Ohio. Recent evidence suggests that the species replacements may be driven by asymmetrical reproductive success favoring 0. rusticus. Nonetheless, some sympatric associations appear locally persistent. Because crayfish demonstrate size-assortative mating and ...
