Drawing Realistic Textures in Pencil
ISBN: 9780891348689 / Angielski / Miękka / 1999 / 128 str. Termin realizacji zamówienia: ok. 8-10 dni roboczych. You won't believe the incredible drawings you can create using common pencils and the special techniques illustrated in this book. These methods are so easy that anyone--from doodler to advanced artist--can master them in minutes Step by step, you'll learn how to capture the look of metal, glass, weathered wood, skin, hair and other textures. Two detailed start-to-finish demonstrations show you how to use these textures to create drawings that look so real they seem to leap right off the page.

Optically Trapped Microspheres as Sensors of Mass and Sound
ISBN: 9783031443312 / Angielski / Twarda / 2023 Termin realizacji zamówienia: ok. 20 dni roboczych. This thesis makes significant advances in the use of microspheres in optical traps as highly precise sensing platforms. While optically trapped microspheres have recently proven their dominance in aqueous and vacuum environments, achieving state-of-the-art measurements of miniscule forces and torques, their sensitivity to perturbations in air has remained relatively unexplored. This thesis shows that, by uniquely operating in air and measuring its thermally-fluctuating instantaneous velocity, an optically trapped microsphere is an ultra-sensitive probe of both mass and sound. The mass of... This thesis makes significant advances in the use of microspheres in optical traps as highly precise sensing platforms. While optically trapped mi... |
