This two-day conference highlights the accomplishments of students who have immersed themselves in faculty- mentored research and creative projects. Promoting collaboration between students and faculty in research is central to the mission of our campus, and I am proud of the long-standing tradition in undergraduate research at UC Davis. The work you will see here represents the passion students have for their topics of study and their excitement to share their results with the public. These students have dedicated a great deal of time and sweat equity to their research. They have learned how to approach problem- solving and how to overcome challenges. They have garnered valuable experience with time management. They are actively honing their skills for communication. There will be some nervous looks on our students’ faces today, but every one of them should be proud to be participating. As someone who spent years working in research labs, I commend the students on the diligence, creativity, and courage required to bring them here today. I also want to offer my deepest thanks to the faculty mentors who engaged, challenged and inspired these undergraduates in their research projects. The mentorship and supervision of student researchers requires dedication and a degree of altruism. I truly appreciate our faculty’s commitment to mentoring students. The many faculty volunteers who have taken time out of their schedules to moderate oral and poster sessions also deserve our gratitude. Without your participation, this event would not be possible. My warm congratulations to the Undergraduate Research Center for its organization of the conference and its tireless dedication to connecting students with research opportunities. The Center represents our campus’s commitment to exposing students to training that can connect the theoretical foundations of their coursework with research and critical thinking skills that will prepare them for their future careers. I invite you to sample all that the conference has to offer and let yourself to be amazed and inspired by the incredible accomplishments of the dedicated young people who will be presenting their work in the poster and oral sessions. Thank you for participating in this celebration of undergraduate research, scholarship and creative excellence! Linda P.B. Katehi Chancellor UC Davis 26th Annual Undergraduate Research, Scholarship and Creative Activities Conference 26th Annual Undergraduate Research, Scholarship and Creative Activities Conference Vice Provost and Dean’s Welcome May 1, 2015 Dear Colleagues, Presenters, and Guests: Welcome to the 26th annual UC Davis Undergraduate Research, Scholarship, and Creative Activities Conference. More than 500 students, representing each of our colleges and divisions, will present their work at this two-day event. The conference’s format encourages all who attend to encounter new discoveries within and beyond their own disciplines. Here you will meet students working to advance solutions in health, agriculture, world hunger, and renewable energy. They are contributing to cutting-edge design and engineering breakthroughs. They are forging a better understanding of critical issues in human development and human rights. They are discovering data that lead to a better understanding of ourselves as human beings. And all of this new knowledge is coming to us in a cacophony of formats from colorful posters to complex charts and graphs to impassioned presentations and engaging exhibits of objects and spaces. Take time to engage with and learn from our students. Ask them how they found their projects. Re-create with them the moment in a class or reading a text or settling into a new lab position or internship or talking with a friend late at night when they happened upon a topic that grabbed them. Ask them who they learned from. You’ll no doubt hear about amazing faculty who are truly engaged with undergraduate research and the dedicated teaching assistants and postdoctoral scholars who round out our instructional teams. And ask them what they’ve discovered that’s really new. You’ll be surprised at how many students have found, in the midst of so much that we already know, things we don’t. They’re asking new questions, demanding new answers, and in so doing improving the world we live in for the generation to come. To the students who are sharing their research and creative projects this weekend, I offer my congratulations and best wishes. To our mentors, I offer my thanks for your commitment to our undergraduates. All of you make real the promise of our world-class research and teaching institution. Lastly, I commend the Undergraduate Research Center for hosting this conference this year as they have each year since 1990, with great care, attention to detail, and commitment to the highest standards of student excellence. As each student participating over the next two days can assure you, the URC’s commitment to engaging UC Davis students in world-class research is a model for us all.

  • Freelensing Presentation
    FREELENSING WORKSHOP NOTES by ALMITRA HILL These notes are taken from a workshop presentation by Almitra Hill at Lane Cove Creative Photography on Thursday 3 May 2018. WHAT IS FREELENSING? An alternative shooting technique where an interchangeable lens is detached from the camera body and held up to the mount opening during exposure. The lens is often tilted to distort the focal plane and selectively focus. Distinctive features include: wedge of focus, distorted perspective, softness/blur, light leaks, flare. Above: some examples of freelensed images STARTING OUT Which lens to use • A “normal” prime lens is a good place to start (35mm or 50mm) but zoom lenses can be used. • Something lightweight that is easy to handle. • A slower maximum aperture can be handy. • Manual aperture ring is extremely useful. • Vintage lenses are great! • A different-mount lens with a longer register/flange focal distance will enable more distant focus (e.g. Nikon lens with Canon body). A note on aperture… • Default apertures depend on the make and mount of lens: Canon-mount lenses default to wide open when detached, most other lenses default to fully stopped down. • TIP: Canon users can hold down the DoF preview button while detaching a lens (with the power on) and the aperture will remain as set. www.lanecovecreativephotography.org • Nikon, Pentax, Sony, Sigma, Tamron etc lenses have an aperture control lever on the rear of the lens that can be held open with a small piece of card/plastic/hairtie. • Manual aperture rings allow you to stop down mechanically. Setting exposure • Meter electronically: Canon and Nikon meters still function with the lens detached.

  • Applications of the Fresnel Diffraction of Neutrons
    f\u-*•? 0 *o •? ^- UM-P-78/43 APPLICATIONS OF THE FRESNEL DIFFRACTION OF NEUTRONS A. G. Klein and G. I. Opat School of Physics, University of Melbourne, Parkville, Victoria, Australia 3052 ABSTRACT The place of Fresnel diffraction in the overall scheme of neutron interference experiments is outlined and possible applications are discussed in the areas of: magnetic domain visualisation; measurement of nuclear scattering lengths with ver/ small specimens; focussing of long wavelength neutron beams using zone plates. 1. INTRODUCTION In classical optics, two principal types of interference experiment are distinguished: interference by amplitude division and interference by division of wavefront. The first of these, typified by the Michelson and Mach-Zehnder interferometers and by various thin film interference situations, relies on partial reflection, i.e. beam-splitters. They find their realisation in the case of neutron optics in the highly successful single crystal interferometers , in which the dynamical Bragg diffraction of neutrons provides the beam-splitting. Another situation of inter­ ference by amplitude division has been manifested in thin film 2 experiments with neutrons . Interference by division of the wavefront has as its paradigm Young's two-slit experiment, in which spatially separated parts of a coherent wavefront are recombir.ed. One of the classical variants of this scheme is the Fresnel bi-prism experiment which has also been demonstrated in the case of electrons by X A Mollenstedt and, in the case of neutrons by Maier-Leibnitz et al. An even simpler set-up was used by us in 1976 : Naufron b«om from cold Moneehrofflotor Cryttol. o« 200 mm.

Not only does the archival quality of the resulting image matter but a simple understanding of lighting can achieve an enormous impact on the given textures, form and inherent detail of objects, giving valuable information which is often lost. Depending on the complexity of the artefacts’ shape, lighting can be experimented with by finding the best position and angle of the lights used for the job. It is often a laborious job to find the time to read up on the correct lighting positions for any given artefact. Often, it is far better to spend some time experimenting and observing, to find the best solution in any given situation. This will help you to judge artefacts by eye, leading to an implicit understanding of the qualities of light and should lead to sound practical experience, which should then become second nature. Simple lighting or copy stands can be cheaply purchased or rigs can be built out of simple materials utilizing desk lamps if your budget is limited. See final section on how to improvise with lighting.

  • Special Techniques to Make Your Image Different
    Special techniques to make your image different 1. Timelapse in one image During a photo tour in Yunnan province, China, we go shoot at a busy local market. I, however, like to experiment something new, presenting the hustle and bustle of the market photographically in a unique way: A time-lapse compressed into one image. To achieve the result, 2 approaches coming to my mind: Option 1. Using the in-camera Multiple exposure mode: Nikon cameras has multiple exposure functions for long time. After years of being ignored, it finally comes to Canon cameras starting 5D III, which I happen to use. This one is shot using "Average" mode in multiple exposure, I set total of 9 exposures, taking one shot every couple seconds, the exposure is automatically reduced, proportional to the number of shots taken, to avoid over-exposing common areas or overlapping bright areas. Where overlapping areas do occur, the final brightness level will be the same as the would have been in a single, properly- exposed shot. And, any non-overlapping areas will be darkened. The final combined image is automatically generated by the camera. The pro is that you can experiment a lot with this technique, simple and fast. The con however, is that you have no control on the resulting image at all. The camera has full control here. Option 2. Taking a lot shots and manipulate them in post processing: This is a hard way, but you have absolute control of the final image. It, however, is time-consuming and requires lots of fiddling with Photoshop.

Box 162700, Orlando, FL 32816-2700, USA Received 23 March 2005; received in revised form 25 October 2005; accepted 27 October 2005 Abstract The design of plane Fresnel zone plates, and binary-staircase kinoforms, has been analyzed in this paper for a non-imaging applica- tion aimed to increase the performance of point-like detectors. They maximize the irradiance at the focal point of the diffractive element maintaining some constrains in the lateral size of the element. The design of the binary-staircase kinoform has been described as an iter- ative process. Some interesting results have been obtained for the values of the relative aperture number, or F/#. The practical case trea- ted here produces elements with very low F/#. The results shows that the gain of the irradiance at the focal point increases with the focal distance of the binary-staircase kinoform, and decreases with the focal length for a plane Fresnel zone plate having a limited lateral size.
