No full textThis paper reports on a high-resolution lensless fluorescence imaging system using membrane deflection for reducing the gap between fluorescent samples and a CMOS image sensor array. The presented system applied the principle of the total internal reflection of excitation light inside a PDMS chip to minimize the exposure of excitation light to the image sensor. We integrated a very thin (5.5 μm) PDMS membrane as a flexible deflector, which allowed for significant reduction of the gap (∼20 μm) inevitably created during the conventional packaging (i.e., wire bonding) of image sensors. In the fabricated system, we achieved minimum distance of 7.5 μm between fluorescent samples and an image sensor array. This reduced gap almost directly corresponds to a resolution as high as ∼7.5 μm, based on the point spread function (PSF)
local dimming and autostereoscopic display
No full text학위논문(박사) - 한국과학기술원 : 전기및전자공학부, 2019.2,[xi, 77 p. :]In this dissertation, two LGPs for local dimming and autostereoscopic display are introduced. The brief intro-duction is below:
i. Local Dimming (Chapter 3)
Two-dimensional local dimming is a technique for reducing energy consumption and enhancing the contrast ratio of LCD. For this, locally luminance controllable BLU is required. Conventional local dimming BLU is made by back-lit type, which has comparably thick feature, or edge-lit type with limited local dimming per-formance. In this dissertation, an ultra-thin BLU for 2D local dimming was proposed and demonstrated by using newly designed LGP. The LGP shows the on-axis light extraction feature without prism sheets. Moreo-ver, due to its unique design of thin channel between each block, local isolation level is controllable.
ii. Autostereoscopic Display (Chapter 4)
An autostereoscopic display is a device for giving binocular disparity without any special glasses. Conven-tional ways to make autostereoscopic display are a temporal and spatial modulation. The proposed LGP can spatially modulate the scene of the display without any additional films like a barrier and a lenticular lens. So it reduces the thickness and cost of the display. The LGP also can be used in two-layered BLU for 2D/3D switchable display because the LGP is transparent. Moreover, I proposed a systematic feature for increasing viewing number and resolution by using spatial-/temporal- hybrid modulation.한국과학기술원 :전기및전자공학부

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
