Usability Study of a Wireless Monitoring System among Alzheimer’s Disease Elderly Population
No full textHealthcare technologies are slowly entering into our daily lives, replacing old devices and techniques with newer intelligent ones. Although they are meant to help people, the reaction and willingness to use such new devices by the people can be unexpected, especially among the elderly. We conducted a usability study of a fall monitoring system in a long-term nursing home. The subjects were the elderly with advanced Alzheimer’s disease. The study presented here highlights some of the challenges faced in the use of wearable devices and the lessons learned. The results gave us useful insights, leading to ergonomics and aesthetics modifications to our wearable systems that significantly improved their usability and acceptance. New evaluating metrics were designed for the performance evaluation of usability and acceptability

The invisible ideology of white light
No full textThis paper explores the role of white light in film history. It argues that, though we live our lives immersed in ‘white’ daylight, the historical hegemony of white light within moving images has been far from inevitable. The paper elaborates this claim by focusing on how and why Technicolor Inc. predicated its infamous but influential ‘law of emphasis’ on white balanced lighting, and by foregrounding ways in which subsequent uses of and discourses about colour in film have assumed the presence of full-spectrum light. Having drawn attention to this imperceptible – and so, until now, unnoticed – visual ideology, the paper then explores cinematic challenges to the hegemony of white light in films including South Pacific, Querelle and Chunkging Express
MIMS: A Minimally Invasive Monitoring Sensor Platform
No full textThis paper describes a minimally invasive sensor platform for active and passive monitoring of human movements and physiological signals. Such a system is needed in cases where 24 #x00D7; 7 monitoring is required, as in older adults with cognitive impairment, dementia and Alzheimer's disease. The passive monitoring systems used today are useful only in detecting events after they happen; the accuracy and speed of detection is questionable. The noninvasive nature of such systems does not bring trade off benefits to early detection and prevention of emergency incidents. We compare some existing sensor platforms and present our monitoring approach using minimally invasive wearable sensor device(s). With a Minimally Invasive Monitoring Sensor (MIMS), using advanced intelligent systems, we analyze the physiological signal data preceding potential emergency events in order to predict them quickly. The Virtual Hub is the core component of MIMS, which acts as a gateway between a monitored person and her/his caregivers, as well as a shared access point between active and passive sensing devices. Some preliminary results are presented here from our sleep-related fall study using two heterogeneous sensor systems
Dynamics of finite-sized light spheres in turbulence
No full textWe report experimental results on the Lagrangian dynamics of finite-size light particles in turbulence. Using an orthogonal camera setup and 3D particle tracking, we study the velocity and acceleration statistics of rigid light spheres in a water tunnel with nearly homogeneous and isotropic turbulence. The Reynolds number (ReY) is varied from 180 to 300, and the study covers a range of size ratios (4 < D/η < 16) for marginally light spheres. We find that the normalised acceleration PDF decreases in intermittency with increasing size ratio - in qualitative agreement with the predictions of the Faxén corrected model. We also present preliminary results on the rotational dynamics of large light spheres in turbulence
Interview with Dr. Michael C. Keith (Communication Department), author Of Night and Light: Stories (Blue Mustang Press, 2012)
No full textDr. Keith's latest book is a collection of shorts stories entitled Of Night and Light. This book collects more than 40 short stories covering all manner of speculative fiction, humor, and even a bit of romance. As the title notes, there are both light and dark themes within the book, though the author readily admits he leans a bit darker at times.Title supplied by cataloger
Stereoscopic Clustered Light Shading
No full textReal-time realistic rendering requires the evaluation of the influence of many light sources. In case of dynamic geometry or light sources, this evaluation must be performed every frame. In this thesis I present enclosed clustering: an adaptation of Clustered Light Shading to stereoscopic rendering which cuts the per-eye cost of light assignment in half. To achieve this, clustering is performed once with a clustering camera frustum that encloses both of the eye camera frusta. Decoupling of the clustering camera from the rendering camera gives way to two alternative ways of constructing the clustering: orthographic clustering and displaced perspective clustering. Orthographic clustering uses a uniform world-space grid and has been traditionally dismissed. Displaced perspective clustering uses a decoupled clustering camera to reduce the number of small clusters near the camera. These techniques can be applied to both monoscopic and stereoscopic rendering

Publisher Copyright: © 2021 by the author. Licensee MDPI, Basel, Switzerland.Organic light emitting transistors (OLETs) represent a relatively new technology platform in the field of optoelectronics. An OLET is a device with a two-fold functionality since it behaves as a thin-film transistor and at the same time can generate light under appropriate bias conditions. This Review focuses mainly on one of the building blocks of such device, namely the gate dielectrics, and how it is possible to engineer it to improve device properties and performances. While many findings on gate dielectrics can be easily applied to organic light emitting transistors, we here concentrate on how this layer can be exploited and engineered as an active tool for light manipulation in this novel class of optoelectronic devices.Peer reviewe

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
