The History of Visual Magic in Computers: How Beautiful Images are Made in CAD, 3D, VR and AR
Year: 2013

If you have ever looked at a fantastic adventure or science fiction movie, or an amazingly complex and rich computer game, or a TV commercial where cars or gas pumps or biscuits behaved liked people and wondered, How do they do that? then youve experienced the magic of 3D worlds generated by a computer.3D in computers began as a way to represent automotive designs and illustrate the construction of molecules. 3D graphics use evolved to visualizations of simulated data and artistic representations of imaginary worlds. In order to overcome the processing limitations of the computer, graphics had to exploit the characteristics of the eye and brain, and develop visual tricks to simulate realism. The goal is to create graphics images that will overcome the visual cues that cause disbelief and tell the viewer this is not real. Thousands of people over thousands of years have developed the building blocks and made the discoveries in mathematics and science to make such 3D magic possible, and The History of Visual Magic in Computers is dedicated to all of them and tells a little of their story. It traces the earliest understanding of 3D and then foundational mathematics to explain and construct 3D; from mechanical computers up to todays tablets. Several of the amazing computer graphics algorithms and tricks came of periods where eruptions of new ideas and techniques seem to occur all at once. Applications emerged as the fundamentals of how to draw lines and create realistic images were better understood, leading to hardware 3D controllers that drive the display all the way to stereovision and virtual reality.
Persistent Postural Perceptual Dizziness.
Venue: Seminars in neurology
Year: 2020

Persistent postural perceptual dizziness (PPPD) was defined for the International Classification of Vestibular Disorders in 2017. It is a chronic vestibular disorder that manifests with waxing and waning symptoms of dizziness, unsteadiness, or nonspinning vertigo that last for 3 months or more and are exacerbated by upright posture, active or passive motion of self, and exposure to environments with complex or moving visual stimuli. Triggers of PPPD include a wide variety of conditions that may cause vestibular symptoms or disrupt balance functioning, including neuro otologic and other medical conditions and psychological distress. The diagnosis is made by identifying key symptoms in patients' histories and conducting physical examinations and diagnostic testing of sufficient detail to establish PPPD as opposed to other illnesses. Ongoing research is providing insights into the pathophysiological mechanisms underlying PPPD and support for multimodality treatment plans incorporating specially adapted vestibular rehabilitation, serotonergic medications, and cognitive behavior therapy.
Using Zoom Videoconferencing for Qualitative Data Collection: Perceptions and Experiences of Researchers and Participants
Year: 2019

Advances in communication technologies offer new opportunities for the conduct of qualitative research. Among these, Zoom an innovative videoconferencing platform has a number of unique features that enhance its potential appeal to qualitative and mixed methods researchers. Although studies have explored the use of information and communication technologies for conducting research, few have explored both researcher and participant perspectives on the use of web and videoconferencing platforms. Further, data are lacking on the benefits and challenges of using Zoom as a data collection method. In this study, we explore the feasibility and acceptability of using Zoom to collect qualitative interview data within a health research context in order to better understand its suitability for qualitative and mixed methods researchers. We asked 16 practice nurses who participated in online qualitative interviews about their experiences of using Zoom and concurrently recorded researcher observations. Although several participants experienced technical difficulties, most described their interview experience as highly satisfactory and generally rated Zoom above alternative interviewing mediums such as face to face, telephone, and other videoconferencing services, platforms, and products. Findings suggest the viability of Zoom as a tool for collection of qualitative data because of its relative ease of use, cost effectiveness, data management features, and security options. Further research exploring the utility of Zoom is recommended in order to critically assess and advance innovations in online methods.

Incidence, Type, Related Factors, and Effect of Workplace Violence on Mental Health Nurses: A Cross sectional Survey
Venue: Archives of psychiatric nursing
Year: 2018

Workplace violence and its impact on mental health nurses have yet to be thoroughly explored in China. This study aims to investigate the incidence, type, related factors, and effects of workplace violence on mental health nurses as well as identifying coping strategies.  A researcher designed workplace violence questionnaire and the Maslach Burnout Inventory General Survey were distributed to nurses at a mental health hospital in Wuhan, China.  Most nurses reported a high incidence of workplace violence (94.6% in the past year ranging from verbal aggression, sexual harassment, to physical attack. The forms of violence significantly correlated with each other (r 0.5, p 0.000) Working on the psychiatric intensive care unit for adult males and being a male nurse placed nurses at significantly higher risk for workplace violence. Providing routine treatment, caring for male patients, and working the night shift increased the risk of sexual harassment. Nurses who believed that workplace violence was preventable experienced a significantly lower incidence of violence. Burnout levels of the mental health nurses were relatively mild, but increased with age, professional title, years of employment and frequency of workplace violence.  The incidence of workplace violence among mental health nurses is common, and its frequency is correlated with nurses' level of burnout. Management and clinical nurses should work together on an organization wide strategy targeting the major identified risk areas to reduce the incidence of workplace violence and minimize its impact on nurses. HIGHLIGHTSThe incidence of workplace violence on mental health nurses was high.Significant risk factors for workplace violence were working on the psychiatric intensive care unit and being a male nurse.Workplace violence reduced with prevention, de escalating skills, effective coping strategies, and communication skills.
Measuring and Profiling Self Regulated Learning in the Online Environment:
Year: 2010

While the presence of technology enhanced learning environments (TELEs) will only increase in higher education, this book chapter examines current literature concerning the measurement of online SRL behaviors and the application of this online SRL measurement with regard to profiling SRL behaviors in TELEs. The methodologies and issues associated with the measurement of SRL behaviors in TELEs is discussed in view of extant research. The organization of SRL behaviors into five, distinct profiles is then discussed in view of a social cognitive perspective concerning the development of SRL (e.g. Zimmerman Schunk, 2001) The book chapter concludes with recommendations for future research concerning the presence of SRL profiles and their relationship to other metacognitive factors and academic achievement.
Fast Paxos Made Easy: Theory and Implementation
Venue: Int. J. Distributed Syst. Technol.
Year: 2015

Distributed consensus is one of the most important building blocks for distributed systems. Fast Paxos is one of the latest variants of the Paxos algorithm for distributed consensus. Fast Paxos allows an acceptor to cast a vote for a value of its choice unilaterally in a fast round, thereby eliminating a communication step for reaching consensus. As a tradeoff, the coordinator must build a quorum that is bigger than the simple majority used in Classic Paxos. This article presents the theory, implementation, and a comprehensive performance evaluation of the Fast Paxos algorithm. The theory is described in an easier to understand way compared with the original article by Lamport. In particular, an easy to implement value selection rule for the coordinator is derived. In the implementation of Fast Paxos for state machine replication, a number of additional mechanisms are developed to cope with practical scenarios. Furthermore, the experiments reveal that Fast Paxos is most appropriate for use in a single client configuration. The presence of two or more concurrent clients even in a local area network would incur frequent collisions, which would reduce the system throughput and increase the mean response time as experienced by clients. Due to frequent collisions, Fast Paxos actually performs worse than Classic Paxos in the presence of moderate to large number of concurrent clients.

EFFECTS OF UNFOLDING TECHNIQUES AS DESIGN STIMULI IN BUILDING DESIGN
Year: 2018

Through paper folding techniques, i.e. origami, people can make fascinating 3D forms from 2D sheets. Many architects utilise folding techniques in their design process as design stimuli. However, the reverse process, unfolding 3D forms, presents computational geometry problems, and there is limited research that clarifies how designers can use theses unfolding techniques. In this study, we begin by introducing a computational geometry method for generating common developments by unfolding 3D plural cuboids. Next, this paper presents the results of an experiment where extended protocol analysis methods were used to examine the effects of using the unfolding techniques as design stimuli during concept generation. The results show that the unfolding techniques promote creativity in building design and enhance participants' extension of idea space from the microscopic perspective.
Covalent Organic Framework Film for Three State Near Infrared Electrochromism and Molecular Logic Gate.
Venue: Angewandte Chemie
Year: 2021

A Kagome structure covalent organic framework (COF) film with three state near infrared (NIR) electrochromic properties was designed and synthesized. The morphology and structure characterization revealed that the COFTPDA PDA film was composed of hexagonal nanosheets with high crystallinity. The COFTPDA PDA film exhibit three reversible color states at different applied potentials, and high absorption spectra changes in the NIR region, which can be ascribed to the strong intervalence charge transfer (IVCT) interaction of the Class III mixed valence systems of the conjugated triphenylamine species. The COFTPDA PDA film showed the sub second response time (1.3 s for coloring and 0.7 s for bleaching at 1050 nm) and the long retention time in the NIR region. In comparison with the amorphous film with the same monomers, COFTPDA PDA film show superior NIR electrochromic properties in term of response time and stability, which could be attributed to the highly ordered porous structure and the p p stacking structure of the COFTPDA PDA architecture. Furthermore, the COFTPDA PDA film was successfully applied in mimicking flip flop logic gate with optical memory functions.
La Verite. Verite et credibilite: construire la verite dans le systeme de communication de l'Occident (XIIIe XVIIe siecle) ed. by Jean Philippe Genet (review)
Year: 2018

Katie Peebles then turns our attention to the seventeenth century in her examination of John Aubrey's influential Monumenta Britannica. Dustin M. Frazier Wood picks up on Aubrey's interest in the Boarstall Horn in a discussion of the broader significance of charter horns in late medieval and early modern England. Renee Ward looks at two adaptations of the Griselda story by Louisa Hervey which show the author's dissatisfaction with the social systems that inform the medieval versions of her story. If Hervey's agenda is overtly political, Harlan Ellison's embrace of Dante may be less so. Jeremy Withers argues that in Ellison's 'I Have No Mouth and I Must Scream' references to Dante, specifically his approach to having the punishment fit the crime, only compound the horrors inflicted upon the characters in the story by a sentient supercomputer. Carol Jamison examines textual interlacement in George R. R. Martin's A Song of Fire and Ice, seeing his narrative techniques as copying those of Malory and other writers of Arthurian romance. If Ellison moves beyond the medieval, Martin moves back to it as an anchor for his immensely popular series of novels. Elan Justice Pavlinich looks beyond literature to examine Disney's embrace of medievalism in Maleficent as a way for the corporation to at best pay lip service to progressive causes. The same can be said, Ann F. Howey suggests, for attempts at (neo)medievalism on the part of two television series from the 1990s, Babylon 5 and Crusade. Kara L. McShane argues that such mixed agendas also seem to inform Netflix's Marco Polo, which links Orientalism with medievalism in at times troubling ways. The 2014 television program The Quest is, according to Angela Jane Weisl, more successful in its use of cartography to allow medievalism to provide a window into the past. Paul B. Sturtevant follows with a qualitative survey of the perceptions which a select group of university undergraduates hold about the Middle Ages and medievalism. Dean Swinford ends the volume on no pun intended a different note by examining the intersection of the medieval and black metal music, specifically in Mayhem's De Mysteriis Dom Sathanas. Taken individually, some of the essays here offer valuable new insights into (neo)medievalism in its many forms, but the newness of ecomedievalism as a field partly contributes to a lack of any real cohesiveness of the volume. Such cohesiveness might be more apparent with the addition of an index, which would help readers to see more easily connections among the volume's fifteen essays. Kevin j. harty, La Salle University
Fast locking adaptive PLL using Dual Edge Phase Frequency Detector
Venue: Microelectron. J.
Year: 2015

Three stage PLL with a Dual Edge Phase frequency Detector (DE PFD) is proposed to reduce the locking time and to reduce jitter when locked. The DE PFD speeds up the locking time by detecting the phase difference between the reference clock signal and the PLL's feedback signal of the divider circuit in both the rising edge and the falling edge. Meanwhile, the control signal generated from the DE PFD can switch the loop bandwidth automatically. The locking status detection using DE PFD saves the hardware overhead and switches the bandwidth smoothly. The DE PFD is switched to the single edge PFD to decrease the jitter further when the PLL is locked. The implemented proposed three stage 1.6GHz PLL under the TSMC 0.18um CMOS process shows the pre simulation result of 56% locking time improvement as compared to the conventional PLL and the measured results of the RMS jitter reduced from 13.36 to 11ps and the peak to peak jitter from 60ps to 44ps. When the bandwidth switching mechanism is activated, the power level of interference is reduced by 10dBm.
Markets and Networks in International Trade: On the Role of Distances in Globalization
Year: 2010

The enduring importance of geographic distance as an impediment to international trade has recently become recognized as an empirical fact in need of explanation. According to one line of argument the 'network view' the continuing high sensitivity of international trade to geographical distance is associated with a shift in the composition of trade towards goods requiring more extensive information exchange and personal interaction between buyers and sellers. An alternative explanation 'the market view' contends that improved availability of information and increasing transparency of markets have facilitated the matching of geographically more proximate buyers and sellers, and that the observed decline in average transportation distances is a reflection of increasingly efficient markets.This paper examines empirically the merits of these two arguments based on a longitudinal analysis of bilateral trade between 25 major trading nations for the period 1962 2008. It compares the development of the relative importance of 'psychic distance' a proxy for information related transaction costs and geographic distance a proxy for transportation costs in three categories of goods.The results are broadly in support of the 'market view' showing that the sensitivity of trade to psychic distance has declined dramatically for all categories of goods. The impact of geographic distance has increased markedly for homogenous goods, whereas for more differentiated goods it has decreased mildly.
Satellite 5G Integration: A Network Perspective
Venue: IEEE Network
Year: 2018

Future 5G mobile communication systems are expected to integrate different radio access technologies, including the satellite component. Within the 5G framework, the terrestrial services can be augmented with the development of HTS systems and new mega constellations meeting 5G requirements, such as high bandwidth, low latency, and increased coverage including rural areas, air, and seas. This article provides an overview of the current 5G initiatives and projects followed by a proposed architecture for 5G satellite networks where the SDN/NFV approach facilitates the integration with the 5G terrestrial system. In addition, a novel technique based on network coding is analyzed for the joint exploitation of multiple paths in such an integrated satellite terrestrial system. For TCP based applications, an analytical model is presented to achieve an optimal traffic split between terrestrial and satellite paths and optimal redundancy levels.
