Digital data reformatter/deserializer
A method and apparatus is presented for reformatting and de-serializing a serially-received sequence of data words, each consisting of a fixed number of binary data bits. A block of nm bits is serially fed into a shift register or serially-connected group of shift registers. In lieu of the(nm-1)th shifts, the bits are rearranged within the shift register in parallel fashion, according to a prescribed scheme. Shifting then continues, until the first bit of each data word appears in the last bit position in the shift register, at which time that data word is shifted in parallel into an output buffer stage, from which it is outputted in parallel, after a fixed delay
Analysis, Tracing, Characterization and Performance Modeling of Select ASCI Applications for BlueGene/L Using Parallel Discrete Event Simulation
Caltech's Jet Propulsion Laboratory (JPL) and Center for Advanced Computer Architecture (CACR) are conducting application and simulation analyses of Blue Gene/L[1] in order to establish a range of effectiveness of the architecture in performing important classes of computations and to determine the design sensitivity of the global interconnect network in support of real world ASCI application execution
Workflow and Best Practices of Planting Design in Virtual Reality
The purpose of this study is to develop a technical workflow and deliver an instructional module for teaching planting design in Virtual Reality (VR). The developed workflow and instructional model will be presented to students enrolled at Utah State University in the Landscape Architecture and Environmental Planning (LAEP) Department. The first objective of this thesis project is to explore and create a successful workflow of basic planting design principles and apply them in virtual reality with the use of new technology. The virtual reality and planting design software that were explored were Twinmotion, VR Sketch, SketchUp, AutoCAD, Land FX, Gravity Sketch, and Unreal Engine 5. After exploration and testing, Unreal Engine 5 and Gravity Sketch were not used, due to the programs either being too complicated to learn in a short amount of time, or because the program was to be used for a portion of the design process not included in this workflow. The creation of a workflow will introduce the application of virtual reality technology into the landscape architecture industry by preparing students with the requisite knowledge to successfully design in virtual reality prior to their entry into the workforce. The second objective is to introduce students to the application of virtual reality in relation to planting design. Students will be introduced to the basics of virtual reality through a walkthrough video and an in-class lecture on the developed workflow, followed by a vignette and a final design assignment. The vignette and the final design will allow students to apply what they have learned via the workflow. These objectives will be achieved using the LAEP 3500 Planting Design course taught during the fall semester to MLA graduate students and matriculated juniors in the LAEP department. Expected results of this thesis include landscape architecture students developing skills to create unique planting designs, within the constraint of given assignments, while using virtual reality technology, which by allows students to view their design âin person.

How to approach research : a guide for child life specialists
This how-to guide aims to increase the understanding of research and provide child life specialists and students a concise and easy tool to access information about how they incorporate research into their work
Tergitol-induced colonial growth without inhibition of conidiation
The cloning of genes from Neurospora crassa usually involves transformation of a mutant with genomic library DNA and the subsequent identification of transformants showing wild-type phenotype (Vollmer and Yanofsky 1986. Proc. Natl. Acad. Sci. 83:4869- 4873). This can be problematic in the case of morphological mutants, because the sorbose- containing medium that is typically used to promote colonial growth of the transformants tends to interfere with conidiation, and sometimes inhibits aerial hyphal growth altogether. The medium described below uses the nonionic detergent tergitol (Tatum et al. 1949. Science 109:509-511) to induce colonial vegetative growth without affecting aerial hyphal growth or morphology
Collectors of Rhodiola species on the Sichuan-Tibetan and Sichuan-Shaanxi borders
Medicinal Rhodiola species, including Rhodiola rosea L. and Rhodiola crenulata (Hook.f. & Thomson) H.Ohba, have been widely used as traditional herbal medicines with numerous claims for their therapeutic effects. Faced with resource depletion, environment destruction and higher demand, R. rosea and R. crenulata are becoming endangered, making them economically even more valuable, but also increasing the risk of adulteration and low quality - and raising awareness for the role of often unlicensed collectors and middlemen.
Although R. rosea is the most well known in Europe, R. crenulata is the recognised species in China. On the border of Sichuan and Tibet, members of the Yi minority collect R. crenulata in order to sell it to the âtraditionalâ Chinese medicine market. Collection of this medicinal herb represents about one third of the annual income for the Yi. Three times a year they climb up to 5,000 metres in search of the plants. As it is stripped out, the Yi have to travel to more and more inhospitable places to ensure its supply.
At Taibai mountain along the border of Sichuan and Shaanxi, the same medicinal plant, hongjingtian in Chinese, is growing in the wild, too. Yet, in a socioeconomic context, collectors do not have a particular ethnic background such as Yi, Tibetan or Han collectors. Here, the collectors are various unlicensed providers-cum-prescribers 'caoyi'. (The term does not mean herb-physician, as one might assume from terms such as caoyao (herbals). It means unofficial or not following the scholarly standard.) Using neither an ethnic identity nor the general botanical terms in Latin, they claim Daoism and terroir of their mountain as a sign of good quality âTaibai hongjingtianâ.
There appears to be no strategy in place to protect the species across all those socioeconomic, ethnic and provincial boundaries, and without some intervention it is likely that R. crenulata will eventually become so rare that it can no longer be collected in the current quantities. This will have consequences both for the livelihoods of the Yi and of various Caoyi, and also for the conservation of R. Crenulata and itâs sustainability
Study of an engine flow diverter system for a large scale ejector powered aircraft model
Requirements were established for a conceptual design study to analyze and design an engine flow diverter system and to include accommodations for an ejector system in an existing 3/4 scale fighter model equipped with YJ-79 engines. Model constraints were identified and cost-effective limited modification was proposed to accept the ejectors, ducting and flow diverter valves. Complete system performance was calculated and a versatile computer program capable of analyzing any ejector system was developed
