Don't Compete....Tilt the Field: 300 irreverent lessons for tomorrow's business leaders - Original PDF
نویسندگان: خلاصه: When I was starting out in business I got very good advice from a friend who said "ninety percent of business is half mental!" I have come to believe those numbers and have found that, if anything, 90% may be too low! In business, as in writing a book, so much depends upon good thinking, lots of discipline, and plenty of support.

Preparing for Blockade 1885–1914 - Original PDF
نویسندگان: خلاصه: Today British strategy is slowly swinging back to the sea, as the critical importance of the wider world as fuel and food security, economic prosperity and diplomatic and cultural links reinforce the hard lessons of the past decade, namely that large-scale land operations are both ineffective and costly methods of waging war on inchoate, amorphous organisations, and large backward states unified by vehement hatred of foreigners
Liberator Band 1 Ausgabe 2 - PDF
نویسندگان: خلاصه: Do you want to recycle your electrical and electronic equipment for free? Learn more Molly Birch has everything a poor City girl could want: an apartment with her own bedroom, two living parents and a boyfriend. But none of it is stable when the anonymous Government dictates all aspects of citizens' lives, from food and medical care access to the number of children couples can have. Molly is sixteen and now old enough to apply for a Courtship with her boyfriend, Gavriel Kingsley. Courtships are the only legal form of romantic relationship for unmarried citizens over sixteen and are the step leading to marriage. Molly and Gavriel have waited years to apply. However, things don't go as planned following their application and medical tests during Clinic Day. The fallout leaves Molly's world shattered, and she makes a desperate and dangerous escape from the only life she's ever known to keep control over something after the Government takes everything from her. On her journey, Molly makes new friends, discovers her dad's secret past, learns her heart's true feelings and finds out how she can make a difference in the City for everyone, not just herself.

Adaptive Optics for Vision Science Principles Practices Design and Applications - Original PDF
نویسندگان: خلاصه: The high transverse resolution of retinal imaging systems equipped with adaptive optics provides a unique opportunity to record these eye move- ments with very high accuracy. Putnam et al. showed that it is possible to record the retinal location of a fixation target on discrete trials with an error at least 5 times smaller than the diameter of the smallest foveal cones [63]. We used this capability to measure the standard deviation of fixation positions FIGURE 1.7 Images of the cone mosaics of 10 subjects with normal color vision, obtained with the combined methods of adaptive optics imaging and retinal densi- tometry. The images are false colored so that blue, green, and red are used to repre- sent the S, M, and L cones, respectively. (The true colors of these cones are yellow, purple, and bluish-purple). The mosaics illustrate the enormous variability in L/M cone ratio. The L/M cone ratios are (A) 0.37, (B) 1.11, (C) 1.14, (D) 1.24, (E) 1.77, (F) 1.88, (G) 2.32, (H) 2.36, (I) 2.46, (J) 3.67, (K) 3.90, and (L) 16.54. The proportion of S cones is relatively constant across eyes, ranging from 3.9 to 6.6% of the total population. Images were taken either 1° or 1.25° from the foveal center. For two of the 10 subjects, two different retinal locations are shown. Panels (D) and (E) show images from nasal and temporal retinas, respectively, for one subject; (J) and (K) show images from nasal and temporal retinas for another subject. Images (C), (J), and (K) are from Roorda and Williams [52]. All other images were made by Heidi Hofer. (See insert for a color representation of this figure.) (From Williams and Hofer [57]. Reprinted with permission from The MIT Press.) across discrete fixation trials, obtaining values that ranged from 2.1 to 6.3 arcmin, with an average of 3.4 arcmin, in agreement with previous studies [63, 64]. Interestingly, the mean fixation location on the retina was displaced from the location of highest foveal cone density by an average of about 10 arcmin (as shown in Fig. 1.8), indicating that cone density alone does not drive the location on the retina selected for fixation. This method may have interesting future applications in studies that require the submicron registra- tion of stimuli with respect to the retina or delivering light to retinal features as small as single cells. Whereas the method developed by our group can only record eye position on discrete trials, Scott Stevenson and Austin Roorda have shown that it is possible to extract continuous eye movement records from video-rate images obtained with an adaptive optics scanning laser ophthalmoscope (AOSLO) [66]. Eye movements cause local warping of the image within single video frames as well as translation between frames. The warping and translation information in the images can be used to recover a record of the eye move- ments that is probably as accurate as any method yet devised. This is illus- trated in Figure 1.9, which compares the eye movement record from the AOSLO with that from a Dual Purkinje Eye Tracker. The noise in the AOSLO trace is on the order of a few arc seconds compared to about a minute of arc for the Dual Purkinje Eye Tracker. Note also the greatly reduced overshoot following a saccade in the AOSLO trace. These overshoots are thought to be partly artifacts caused by lens wobble following the saccade and do not reflect the true position of the retinal image. The AOSLO is not susceptible to this artifact because it tracks the retinal position directly rather than relying on reflections from the anterior optics.
A devil's chaplain: reflections on hope, lies, science, and love - Original PDF
نویسندگان: خلاصه: The first essay in this volume, A Devil's Chaplain (1.1), has not previously been published. The title, borrowed by the book, is explained in the essay itself. The second essay, What is True? (1.2), was my contribution to a symposium of that name, in Forbes ASAP magazine. Scientists tend to take a robust view of truth and are impatient of philosophical equivocation over its reality or importance. It's hard enough coaxing nature to give up her truths, without spectators and hangers-on strewing gratuitous obstacles in our way. My essay argues that we should at least be consistent. Truths about everyday life are just as much - or as little - open to philosophical doubt as scientific truths. Let us shun double standards. At times I fear turning into a double standards bore. It started in child- hood when my first hero, Doctor Dolittle (he returned irresistibly to mind when I read the Naturalist's Voyage of my adult hero, Charles Darwin), raised my consciousness, to borrow a useful piece of feminist jargon, about our treatment of animals. Non-human animals I should say, for, of course, we are animals. The moral philosopher most justly credited with raising today's consciousness in this direction is Peter Singer, lately moved from Australia to Princeton. His The Great Ape Project aims towards granting the other great apes, as near as is practically possible, civil rights equivalent to those enjoyed by the human great ape. When you stop and ask yourself why this seems so immediately ridiculous, the harder you think, the less ridiculous it seems. Cheap cracks like 'I suppose you'll need reinforced ballot-boxes for gorillas, then?' are soon dispatched: we give rights, but not the vote, to children, lunatics and Members of the House of Lords. The biggest objection to the GAP is 'Where will it all end? Rights for oysters?' (Bertrand Russell's quip, in a similar context). Where do you draw the line? Gaps in the Mind (1.3), my own contribution to the GAP book, uses an evolutionary argument to show that we should not be in the business of drawing lines in the first place. There's no law of nature that says boundaries have to be clear-cut.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
