To realize this, the artist Kim Waldron and kimura-lemoine decided to stage photographs of everyday life and key moments of the journey of a fictitious adoption. These photographs tell the story of a Caucasian woman adopted into a Canadian family of Korean descent. By this reversal, these images, at first sight banal, become interesting and intriguing here. The Kim Kim project elaborates Kim Waldron’s previous photographic and video work that incorporates self-portraiture into fictitious situations in order to challenge aspects of identity and social conditioning. Her photographic work uses a documentary aesthetic to make fictional propositions credible. This collaboration with kimura-lemoine uses the aesthetics of family photographs, a Korean family whose surname is Kim and Kim Waldron’s birth parents to create an imaginary and improbable tale of international adoption." -- Artexte website
Particle size effects on the particle deposition from non-isothermal stagnation point flows
No full textThe deposition (transport) of particles onto cold smooth walls (about 1159-1345 K) from high temperature combustion suspensions (about 1565 K) undergoing a two-dimensional stagnation point flow was investigated experimentally for a wide range of particle sizes (having diameter from 0.1 to 30 μm) by SEM (Scanning Electron Microscopy) techniques. Using an LDA (Laser-Doppler Anemometry) system, the velocities of the two-phase and the particle size were measured simultaneously. Particle sizes were measured using the maximum pedestal amplitude of Doppler signal and the visibility. Also, particle motion that considered the effects of thermophoresis and inertial impaction was computed by numerically solving Eulerian partial differential equations of momentum, energy and mass for the gas and particle phases (two-fluid model). The experimental data were compared to the numerical results for variation of Stokes numbers. Good agreements between experimental and numerical results were obtained for velocity, temperature and particle deposition rates. Also, the importance of combined thermophoresis and inertial impaction was examined. © 1991
Protecting Animals 25: Kim Stallwood
No full textThis episode of Knowing Animals is from the Protecting Animals series. I am joined by Kim Stallwood. Kim is a long standing animal advocate, having working for many of the world’s leading animal protection agencies in both the UK and the USA. We talk to Kim about his reflections on that work. They are outlined in his book ‘Growl: Life, Lessons, Hard Truths and Bold Strategies from an Animal Advocate’. Growl was published by Lantern Books in 2014
분산 구동 메커니즘을 내장한 로봇 핑거의 정밀 자세 제어기 설계
No full textIn this paper, we newly propose a novel control strategy of a three joints-robot finger for the purpose of artificial hands. The robot finger is specifically modeled by using a 3D CAD program (CATIA), considering human fingers, and then the proposed control method is verified through the dynamic simulation tool (Simulink and Recurdyn R2). Each slider is individually controlled to be located at the optimal positions where the maximal joint torque can be generated. To prove the effectiveness of the proposed control method, we devise two cases for the reference position of sliders. By comparing the control performance of two cases, the validity of the proposed control method will be verified. © ICROS 2010

Mode decomposition of three-dimensional mixed-mode cracks via two-state integrals
No full textA numerical scheme is proposed to obtain the individual stress intensity factors in an axisymmetric crack and in a three-dimensional mixed-mode crack. The procedures presented here are based on the path independence of J and M integrals and mutual or two-state conservation integrals, which involve two elastic fields. A useful method to decompose the stress intensity factors along curved three-dimensional cracks under mixed mode is derived by using appropriate auxiliary fields for the plane problems. The choice of the auxiliary fields available is critical to success of the present scheme, and in this study it is made of not only the asymptotic plane-strain solution, which requires some remedy in application of the two-state integral due to the lack of equilibrium and compatibility, but a numerical solution with a given stress intensity as well. Some numerical examples of penny-shaped cracks are presented to investigate the applicability and effectiveness of the method for problems of axisymmetric and three-dimensional cracks.
