    2010-12-01

    The need for STEM professional development for K-8 teachers is well documented. Such professional development promises broad impact, but it must have a positive effect on teachers’ knowledge and skills: 1) a focus on content knowledge, 2) opportunities for active learning, and 3) coherence with other activities. However, sustained impact is only achieved through intensive professional development. In response to the need for science education courses for K-8 teachers, for the past three years, the School of Education and the Department of Physics have collaborated to offer K-8 teachers science content courses of extended duration (75 contact hours) that emphasize inquiry based learning and investigation. The School of Education graduate courses have consisted of five three-hour meetings during the months of May and June, and a two week intensive period in July when the participants come for six hours per day. The alignment of these courses with inquiry teaching was confirmed using the Reformed Teaching Observation Protocol (RTOP). Courses offered in this format have been: --Immersion in Green Energy (IGE) -alternative sources of energy and how electricity is generated (75 teachers over the last 3 years), --Immersion in Global Energy Distribution (IGED) -understanding global climate as an outcome of insolation, convection, and radiation (27 teachers over the last 2 years) The Immersion courses cover a spectrum for inquiry learning that begins with introduction to equipment and experiments through guided discovery and culminates with students taking responsibility for defining and completing their own investigative projects. As a specific example, we consider here the IGED course. For IGED, the first five sessions are devoted to content and learning to use experimental equipment such as digital data collection probes to measure temperature, CO2 and salinity. Content addressed during these sessions include the differentiation between conduction, convection, and

    Riveras, Nykkita L.

    2004-01-01

    This summer I am working in the Educational Programs Office. My task is to convert the Aeronautics Interactive Workstation from a Macintosh (Mac) platform to a Personal Computer (PC) platform. The Aeronautics Interactive Workstation is a workstation in the Aerospace Educational Laboratory (AEL), which is one of the three components of the Science, Engineering, Mathematics, and Aerospace Academy (SEMAA). The AEL is a state-of-the-art, electronically enhanced, computerized classroom that puts cutting-edge technology at the fingertips of participating students. It provides a unique learning experience regarding aerospace technology that features activities equipped with aerospace hardware and software that model real-world challenges. The Aeronautics Interactive Workstation, in particular, offers a variety of activities pertaining to the history of aeronautics. When the Aeronautics Interactive Workstation was first implemented into the AEL it was designed with Macromedia Director 4 for a Mac. Today it is being converted to Macromedia DirectorMX2004 for a PC. Macromedia Director is the proven multimedia tool for building rich content and applications for CDs, DVDs, kiosks, and the Internet. It handles the widest variety of media and offers powerful features for building rich content that delivers red results, integrating interactive audio, video, bitmaps, vectors, text, fonts, and more. Macromedia Director currently offers two programmingkripting languages: Lingo, which is Director's own programmingkripting language and JavaScript. In the workstation, Lingo is used in the programming/scripting since it was the only language in use when the workstation was created. Since the workstation was created with an older version of Macromedia Director it hosted significantly different programming/scripting protocols. In order to successfully accomplish my task, the final product required correction of Xtra and programming/scripting errors. I also had to convert the Mac platform

    1993-01-01

    The complete VP4 gene of the human rotavirus (HRV) K8 strain (G1 serotype) was cloned and inserted into the baculovirus transfer vector pVL941 under the control of the polyhedrin promoter. A K8VP4 recombinant baculovirus was obtained by cotransfection of Spodoptera frugiperda (Sf9) cells with transfer vector DNA containing the K8VP4 gene and wild-type baculovirus DNA. Infection of Sf9 cells with this VP4 recombinant baculovirus resulted in the production of a protein that is similar in size and antigenic activity to the authentic VP4 of the K8 strain. Guinea pigs immunized with the expressed VP4 developed antibodies that neutralized the infectivity of the K8 strain. This antiserum neutralized HRV strains belonging to VP4 serotypes 1A, 1B, and 2 with efficiency eightfold or lower than that of the homologous virus, indicating that the human rotavirus K8 strain represents a distinct VP4 serotype (P3). In addition, low levels of cross-immunoprecipitation of the K8VP4 and its VP5 and VP8 subunits with hyperimmune antisera to HRV strains representing different VP4 serotype specificities also suggested that the K8 strain possesses a unique VP4 with few epitopes in common with other P-serotype strains.

    Beauclair, N.

    1984-12-01

    The main and subcomponent French suppliers of aircraft tubes and pipes are discussed, and the state of the industry is analyzed. Quality control is essential for tubes with regard to their i.d. and metallurgical compositions. French regulations do not allow welded seam tubes in hydraulic circuits unless no other form is available, and then rustproofed steel must be installed. The actual low level of orders for any run of tubes dictates that the product is only one of several among the manufacturers' line. Automation, both in NDT and quality control, assures that the tubes meet specifications. A total of 10 French companies participate in the industry, serving both civil and military needs, with some companies specializing only in titanium, steel, or aluminum materials. Concerns wishing to enter the market must upgrade their equipment to meet the higher aeronautical specifications and be prepared to furnish tubes and pipes that serve both functional and structural purposes simultaneously. Additionally, pipe-bending machines must also perform to tight specifications. Pipes can range from 0.2 mm exterior diameter to 40 mm, with wall thicknesses from 0.02 mm to 3 mm. A chart containing a list of manufacturers and their respective specifications and characteristics is presented, and a downtrend in production with reduction of personnel is noted.

    2004-02-01

    Full Text Available Play in the K-8 curriculum? What robotic technologies are currently available for educators having no prior computer programming experience? and How should instruction in robotics technologies for K-8 educators be designed? Robotics engineering courses have provided undergraduate computer science students with opportunities for designing and programming simulations of robotic tasks. In contrast, many teacher education programs have lacked courses in this area. Educators who have not gained a conceptual understanding of computer programming could lack the skills that would have enabled them to successfully integrate robotics technologies into their K-8 curriculum.

    The emissivity of three Ni and Co based aeronautical alloys is analyzed in this paper. These alloys are employed in high temperature environments whenever good corrosion resistance, high temperature resistance and high strength are essential. Thus, apart from the aeronautical industry, these alloys are also used in other technological applications, as for example, aerospace, nuclear reactors, and tooling. The results in this paper extend the emissivity data for these alloys available in the literature. Emissivity dependence on the radiation wavelength (2-22 {mu}m), sample temperature (200-650 {sup o}C) and emission angle (0-85{sup o}) has been investigated. In addition, the effect of surface finish and oxidation has also been taken into consideration. The data in this paper have several applications, as temperature measurement of a target by pyrometry, low observability of airplanes and thermal radiation heat transfer simulation in airplane nozzles or furnaces.

    The successful development of high-temperature superconductors (HTS) could have a major impact on future aeronautical propulsion and aeronautical flight vehicle systems. A preliminary examination of the potential application of HTS for aeronautics indicates that significant benefits may be realized through the development and implementation of these newly discovered materials. Applications of high-temperature superconductors (currently substantiated at 95 k) were envisioned for several classes of aeronautical systems, including subsonic and supersonic transports, hypersonic aircraft, V/STOL aircraft, rotorcraft, and solar, microwave and laser powered aircraft. Introduced and described are the particular applications and potential benefits of high-temperature superconductors as related to aeronautics and/or aeronautical systems.

  1. Achieving QoS for Aeronautical Telecommunication Networks over Differentiated Services

    Science.gov (United States)

    Bai, Haowei; Atiquzzaman, Mohammed; Ivancic, William

    2001-01-01

    Aeronautical Telecommunication Network (ATN) has been developed by the International Civil Aviation Organization to integrate Air-Ground and Ground-Ground data communication for aeronautical applications into a single network serving Air Traffic Control and Aeronautical Operational Communications. To carry time critical information required for aeronautical applications, ATN provides different Quality of Services (QoS) to applications. ATN has therefore, been designed as a standalone network which implies building an expensive separate network for ATN. However, the cost of operating ATN can be reduced if it can be run over a public network such as the Internet. Although the current Internet does not provide QoS, the next generation Internet is expected to provide QoS to applications. The objective of this paper is to investigate the possibility of providing QoS to ATN applications when it is run over the next generation Internet. Differentiated Services (DiffServ), one of the protocols proposed for the next generation Internet, will allow network service providers to offer different QoS to customers. Our results show that it is possible to provide QoS to ATN applications when they run over a DiffServ backbone.

    At the intersection of biology and computer science is the growing field of bioinformatics-the analysis of complex datasets of biological relevance. Despite the increasing importance of bioinformatics and associated practical applications, these are not standard topics in elementary and middle school classrooms. We report on a pilot project and its evolution to support implementation of bioinformatics-based activities in elementary and middle school classrooms. Specifically, we ultimately designed a multi-day summer teacher professional development workshop, in which teachers design innovative classroom activities. By focusing on teachers, our design leverages enhanced teacher knowledge and confidence to integrate innovative instructional materials into K-8 classrooms and contributes to capacity building in STEM instruction.

  4. Inquiry-based course in physics and chemistry for preservice K-8 teachers

    Directory of Open Access Journals (Sweden)

    Michael E. Loverude

    2011-05-01

    Full Text Available We describe an inquiry-based course in physics and chemistry for preservice K-8 teachers developed at California State University Fullerton. The course is one of three developed primarily to enhance the science content understanding of prospective teachers. The course incorporates a number of innovative instructional strategies and is somewhat unusual for its interdisciplinary focus. We describe the course structure in detail, providing examples of course materials and assessment strategies. Finally, we provide research data illustrating both the need for the course and the effectiveness of the course in developing student understanding of selected topics. Student responses to various questions reflect a lack of understanding of many relatively simple physical science concepts, and a level of performance that is usually lower than that in comparable courses serving a general education audience. Additional data suggest that course activities improve student understanding of selected topics, often dramatically.

  8. KEY COMPARISON: Report on key comparison EUROMET.EM-K8 (DC voltage ratio)

    Science.gov (United States)

    Marullo Reedtz, G.; Cerri, R.

    2004-01-01

    The purpose of the regional comparison EUROMET.EM-K8 was to compare the scaling capabilities up to 1000 V DC of the European national metrology institutes, thus extending to Europe the evaluation of equivalence of voltage ratio measurements obtained by the comparison CCEM-K8. Twenty laboratories participated, with the Istituto Elettrotecnico Nazionale Galileo Ferraris (Torino, Italy) acting as pilot laboratory. The circulation of the travelling standard, a resistive voltage divider, started in July 1998 and ended in January 2002. The technical protocol requested the measurement of voltage ratios 1000 V/10 V and 100 V/10 V, the measurement of other ratios being optional. Nineteen laboratories reported measurements of the mandatory ratios. For these ratios, the measurement methods used are described and the process to evaluate the comparison reference value and the degrees of equivalence is reported in detail. The relative uncertainty of the comparison, given by the combination of the uncertainty of the reference value and the instability of the transfer standard, was about 0.26×10-6 for ratio 1000 V/10 V and about 0.16×10-6 for ratio 100 V/10 V, at 95% level of confidence. The results for the optional ratios are reported in an appendix. With some exceptions, the agreement between the results is satisfactory. Main text.

  11. Preservice Teachers' Perspectives on 'Appropriate' K-8 Climate Change and Environmental Science Topics

    Science.gov (United States)

    Ford, D. J.

    2013-12-01

    With the release of the Next Generation Science Standards (NRC, 2013), climate change and related environmental sciences will now receive greater emphasis within science curricula at all grade levels. In grades K-8, preparation in foundational content (e.g., weather and climate, natural resources, and human impacts on the environment) and the nature of scientific inquiry will set the groundwork for later learning of climate change in upper middle and high school. These rigorous standards increase pressure on elementary and middle school teachers to possess strong science content knowledge, as well as experience supporting children to develop scientific ideas through the practices of science. It also requires a set of beliefs - about children and the science that is appropriate for them - that is compatible with the goals set out in the standards. Elementary teachers in particular, who often have minimal preparation in the earth sciences (NSF, 2007), and entrenched beliefs about how particular topics ought to be taught (Holt- Reynolds, 1992; Pajares, 1992), including climate change (Bryce & Day, 2013; Lambert & Bleicher, 2013), may face unique challenges in adjusting to the new standards. If teachers hold beliefs about climate change as controversial, for example, they may not consider it an appropriate topic for children, despite its inclusion in the standards. On the other hand, those who see a role for children in efforts to mitigate human impacts on the environment may be more enthusiastic about the new standards. We report on a survey of preservice K-8 teachers' beliefs about the earth and environmental science topics that they consider to be appropriate and inappropriate for children in grades K-3, 4-5, and 6-8. Participants were surveyed on a variety of standards-based topics using terminology that signals publicly and scientifically neutral (e.g. weather, ecosystems) to overtly controversial (evolution, global warming) science.

    Richmond, C.R.

    1991-01-01

    Teachers need help, not harassment. So do the establishments in which teachers practice their profession. Community resources must be marshalled to provide help to local schools and teachers. In 1990 the National Science Foundation (NSF) established a unique educational activity named the National Teacher Enhancement Program (NTEP). NSF took advantage of the Department of Energy (DOE) sponsored educational programs and resources at several large DOE contractor labs that had had prior experience with DOE supported teacher enhancement programs. While DOE concentrated on teacher enhancement activities for secondary teachers, the NSF concentrated on teachers from grades K-8. The Oak Ridge National Laboratory (ORNL) is the lead organization for both administering and coordinating the grant. Other participating laboratories are Argonne National Laboratory (ANL), Fermi National Accelerator Laboratory (FERMI), Battelle-Pacific Northwest Laboratory (PNL), Lawrence Livermore Laboratory (LLNL) with some support functions provided by Brookhaven National Laboratory (BNL) and the Oak Ridge Associated Universities (ORAU). The program calls for a three week duration workshop to be conducted at each lab followed by in-service training and other activities during the year. The NSF/NTEP protocol calls for networking among the participating organizations and some of the teachers. An assessment effort is also an integral part of the program. 2 refs.

  19. Amino acid contents and transport of fixed N in nodules of Leucaena leucocephala variety K-8

    Energy Technology Data Exchange (ETDEWEB)

    DuBois, J.D.

    1987-04-01

    Seedlings of Leucaena leucocephala var. K-8 were grown with a N-free fertilizer or fertilizer containing /sup 15/N-depleted (NH/sub 4/)/sub 2/SO/sub 4/ (0.01 atom /sup 15/N; 10 ppm). The nodules of 5 month old trees grown on N-free media were used for /sup 15/N-enriched treatment and as controls. Nodules from plants grown on /sup 15/N-depleted media were also used. Nodules were extracted with 0.5% aqueous toluene and aliquots were analyzed with a Beckman 120B Amino Acid Analyzer. Samples were separated into free ammonium, Asp-N, Glu-N, Asn and Gln amide- and amino-N, and remaining amino acids. Fractions were then analyzed for /sup 15/N content. Asn (27.3 umol/gfw) represented 56% of the total free amino acid pool in the nodules. Asn (amide-N and amino-N) also represented approximately 77% of the total N fixed during the one hour /sup 15/N-enriched N/sub 2/ and the /sup 15/N-depleted treatments. Based on these findings and the fact that the ureide fraction is barely detectable in the nodules (0.25 ..mu..mol/gfw), the authors considers L. leucocephala an amide transporter of fixed N. Additional information will be presented on the amino acid contents of tissues, as well as a time course of amino acid content from seed through nodulation.

    2007-12-01

    The Virtual Museum, a Louisiana Board of Regents sponsored SELECT program, is a collaborative project between the Museum of Natural Science and the French Education Project at Louisiana State University. It offers Louisiana science teachers, in-training teachers, and immersion teachers a professional development program via six videoconferences. These videoconferences are broadcast from LSU to six distance-learning sites across the entire state of Louisiana. This unique teacher population was selected because in Louisiana, there are two types of K-8 science teachers: teachers in traditional classroom settings and teachers in immersion programs. In the Foreign language Immersion programs, the target language (French or Spanish) is the language of instruction and communication in the classroom. For each videoconference, teachers are provided content material that is prepared by geology faculty and graduate students, example of ongoing field research by LSU faculty members, classroom-ready activities, information on available loan material and on-line resources, training on the unique Scope-On-A-Rope microscope, pre-made PowerPoint presentations and virtual museum photos, all, in French and in English. Three of the videoconferences emphasize regional and statewide earth science topics including Louisiana fossils, rocks and minerals, and field techniques used to interpret Louisiana's geologic history. The activities provided for teachers are hands-on, inquiry based classroom exercises that focus on the availability of local materials. These activities can also be scaled for use in a variety of grade-levels and teachers are encouraged to use these activities in their classrooms. The program has proven to foster new collaboration between science teachers in regular programs and immersion schools while boosting the interest statewide for natural science topics.

  5. GeoGebra in Professional Development: The Experience of Rural Inservice Elementary School (K-8 Teachers

    2013-07-01

    Full Text Available GeoGebra is an emergent open-source Dynamic and Interactive Mathematics Learning Environment (DIMLE (Martinovic & Karadag, 2012 that invites a modeling perspective in mathematics teaching and learning. In springs of 2010 and 2012, GeoGebra was integrated respectively into two online professional development courses on mathematical problem solving in a rural region of a Midwest state in the USA. Using GeoGebra as a primary tool for modeling and communication, fifty-three K-8 inservice elementary school teachers with no or little previous exposure to DIMLEs participated in the graduate level course, where they experimented with various resources of GeoGebra for mathematical modeling in the broad context of problem solving. The instructional team incorporated a variety of pedagogical components to support teachers’ exploration of the new technologies and the mathematical content, including video-based demonstration, affective intervention, learning with children, and social and cognitive scaffoldings. After intensive online instruction, a 25-item questionnaire was administered to collect data on participants’ attitudes, curricular awareness, mathematical content, and pedagogical reflection regarding the integration of GeoGebra. Based on results of the questionnaire (N = 45, this article provides a preliminary description of inservice elementary school teachers’ learning experience in a GeoGebraintegrated DIMLE setting, including an exploratory dimension analysis of the survey data. Overall, the use of GeoGebra challenged teachers’ view about the nature of mathematics and student-teacher interactions and further enriched their mathematical knowledge and pedagogical choices. The course design, context, and implications for future efforts are discussed.

  6. Teaching strategies and conceptual change in a professional development program for science teachers of K--8

    Science.gov (United States)

    Shen, Ji

    This case study investigates two consecutive science courses for teachers of K-8 in a professional development program at Washington University. It aims (1) to trace the processes of the teachers' conceptual change; (2) to analyze the teaching strategies by course instructors; and (3) to try to establish possible links between the two. To achieve this goal, I build a modeling theory to account for the observations. The main body of the study consists of four sub-cases. The first two cases instantiate the elements of the modeling theory. The opening case of balance shows that learning tools and task structures shape the learning outcome, and discusses cycles of modeling. The case also delineates the strategy that the instructors employed---moving from concrete experience to abstract explanation. The second case of buoyancy demonstrates that the modeling theory is able to explain the origins and forming mechanism of the alternative conceptions held by the teachers. It also shows that the teaching strategies of using alternative conceptions, applying analogies and following a logical sequence helped the teachers build new models. The last two cases demonstrate the ways of improving the competence of modelers. The third case of physical models emphasizes the metacognition of the learner who builds models. It illustrates that teachers' level of self-awareness in learning is increased when the models are physical. It shows that the creativity of modeling is rooted in agency, curiosity, communicability, and confidence, and that a chain of transformation among models is the key of systematizing and forming knowledge. The last case of frames of reference tries to answer the question "what is the justification of models if there are alternatives?" The teachers employed different forms of justification which relied heavily on common sense, authority, relativism, and pragmatism, all of which are not rational. While discussing both the positive and negative traits of these

    Hamilton, C.

    2009-12-01

    Ice, Ice, Baby is a K-8 science program created by the education team at the Center for the Remote Sensing of Ice Sheets (CReSIS), an NSF-funded science and technology center headquartered at the University of Kansas. The twenty-four hands-on activities, which constitute the Ice, Ice, Baby curriculum, were developed to help students understand the role of polar ice sheets in sea level rise. These activities, presented in classrooms by CReSIS' Educational Outreach Coordinator, demonstrate many of the scientific properties of ice, including displacement and density. Student journals are utilized with each lesson as a strategy for improving students' science process skills. Journals also help the instructor identify misconceptions, assess comprehension, and provide students with a year-long science reference log. Pre- and post- assessments are given to both teachers and students before and after the program, providing data for evaluation and improvement of the Ice, Ice, Baby program. While students are actively engaged in hands-on learning about the unusual topics of ice sheets, glaciers, icebergs and sea ice, the CReSIS' Educational Coordinator is able to model best practices in science education, such as questioning and inquiry-based methods of instruction. In this way, the Ice, Ice, Baby program also serves as ongoing, in-class, professional development for teachers. Teachers are also provided supplemental activities to do with their classes between CReSIS' visits to encourage additional science lessons, reinforce concepts taught in the Ice, Ice, Baby program, and to foster teachers' progression toward more reform-based science instruction.

    The course for the future aeronautical communications architecture has been defined for more than 10 years and is known as the Aeronautical Telecommunication Network (ATN). However, the operational implementations of making use of the ATN remain 3-5 years away, and these implementations are still only in the early phases of long-range projects. Thus, it is an objective of this effort to consider what the potential outcome within the air transport industry may be, given the rapid growth in commercial-off-the-shelf (COTS) products, networks, and services that are based upon the Internet TCP/IP protocol suite.

  4. Genetic Evidence for O-Specific Antigen as Receptor of Pseudomonas aeruginosa Phage K8 and Its Genomic Analysis

    Directory of Open Access Journals (Sweden)

    Xuewei ePan

    2016-03-01

    Full Text Available Phage therapy requires the comprehensive understanding of the mechanisms underlying the host-phage interactions. In this work, to identify the genes related to Pseudomonas aeruginosa phage K8 receptor synthesis, 16 phage-resistant mutants were selected from a Tn5G transposon mutant library of strain PAK. The disrupted genetic loci were identified and they were related to O-specific antigen (OSA synthesis, including gene wbpR, ssg, wbpV, wbpO, and Y880_RS05480, which encoded a putative O-antigen polymerase Wzy. The LPS profile of the Y880_RS05480 mutant was analyzed and shown to lack the O-antigen. Therefore, the data from characterization of Y880_RS05480 by TMHMM and SDS-PAGE silver staining analysis suggest that this locus might encode Wzy. The complete phage K8 genome was characterized as 93879 bp in length and contained identical 1188-bp terminal direct repeats. Comparative genomic analysis showed that phage K8 was highly homologous to members of the genus PaP1-like phages. On the basis of our genetic findings, OSA of P. aeruginosa PAK is proven to be the receptor of phage K8. The highly conserved structural proteins among the genetic closely related phages suggest that they may recognize the same receptor.

    Full Text Available The ABC1K family of atypical kinases (activity of bc1 complex kinase is represented in bacteria, archaea and eukaryotes. In plants they regulate diverse physiological processes in the chloroplasts and mitochondria, but their precise functions are poorly defined. ABC1K7 and ABC1K8 are probably involved in oxidative stress responses, isoprenyl lipid synthesis and distribution of iron within chloroplasts. Because reactive oxygen species take part in abscisic acid (ABA-mediated processes, we investigated the functions of ABC1K7 and ABC1K8 during germination, stomatal movement and leaf senescence. Both genes were upregulated by ABA treatment and some ABA-responsive physiological processes were affected in abc1k7 and abc1k8 mutants. Germination was more severely affected by ABA, osmotic stress and salt stress in the single and double mutants; the stomatal aperture was smaller in the mutants under standard growth conditions and was not further reduced by exogenous ABA application; ABA-induced senescence symptoms were more severe in the leaves of the single and double mutants compared to wild type leaves. Taken together, our results suggest that ABC1K7 and ABC1K8 might be involved in the cross-talk between ABA and ROS signaling.

  10. Civilian Aeronautical Futures - The Responsibly Imaginable

    2006-01-01

    Since 1940 Aeronautics has had an immense impact upon Global Human lifestyles and affairs - in both the Civilian and Military arenas. During this period Long distance Train and Ship passenger transport were largely supplanted by Air Travel and Aviation assumed a dominant role in warfare. The early 1940 s to the mid 1970 s was a particularly productive period in terms of Aeronautical Technology. What is interesting is that, since the mid 1970 s, the rate of Aeronautical Technological Progress has been far slower, the basic technology in nearly all of our current Aero Systems dates from the mid 70 s or earlier. This is especially true in terms of Configuration Aerodynamics, Aeronautics appears to have "settled" on the 707, double delta and rotary wing as the approach of choice for Subsonic long haul, supersonic cruise and VTOL respectively. Obviously there have been variants and some niche digression from this/these but in the main Aeronautics, particularly civilian Aeronautics, has become a self-professed "mature", Increasingly "Commodity", Industry. The Industry is far along an existing/deployed technology curve and focused, now for decades, on incremental/evolutionary change - largely Appliers vs. developers of technology. This is, of course, in sharp contrast to the situation in the early-to-later 20th century where Aeronautics was viewed as A Major Technological Engine, much the way IT/Bio/Nano/Energetics/Quantum Technologies are viewed today. A search for Visionary Aeronautical "Futures" papers/projections indicates a decided dearth thereof over the last 20 plus years compared to the previous quarter Century. Aeronautics is part of Aerospace and Aerospace [including Aeronautics] has seen major cutbacks over the last decades. Some numbers for the U.S. Aerospace Industry serve as examples. Order of 600,000 jobs lost, with some 180,000 more on the block over the next 10 years. Approximately 25% of the Aerospace workforce is eligible to retire and the average

    standards for quality of teaching, and an educational agenda that promotes high standards for all students, Aeronautics and Aviation Science: Careers and Opportunities had as its aim to deliver products to schools, both in and outside the project sites, which attempt to incorporate multi-disciplined approaches in the presentation of a curriculum which would be appropriate in any classroom, while also aiming to appeal to young women and minorities. The curriculum was developed to provide students with fundamentals of aeronautics and aviation science. The curriculum also encouraged involving students and teachers in research projects, and further information gathering via electronic bulletin boards and internet capabilities. Though not entirely prescriptive, the curriculum was designed to guide teachers through recommended activities to supplement MCET's live telecast video presentations. Classroom teachers were encouraged to invite local pilots, meteorologists, and others from the field of aviation and aeronautics, particularly women and minorities to visit schools and to field questions from the students.

    2012-01-01

    This paper addresses the major problems/issues with civilian aeronautics going forward, the contextual ongoing technology revolutions, the several emerging civilian aeronautical "Big Ideas" and associated enabling technological approaches. The ongoing IT Revolution is increasingly providing, as 5 senses virtual presence/reality becomes available, along with Nano/Molecular Manufacturing, virtual alternatives to Physical transportation for both people and goods. Paper examines the potential options available to aeronautics to maintain and perhaps grow "market share" in the context of this evolving competition. Many of these concepts are not new, but the emerging technology landscape is enhancing their viability and marketability. The concepts vary from the "interesting" to the truly revolutionary and all require considerable research. Paper considers the speed range from personal/general aviation to supersonic transports and technologies from energetics to fabrication.

    2004-01-01

    Aviation industries in United States and in Europe are undergoing a major paradigm shift in the introduction of new network technologies. In the US, NASA is also actively investigating the feasibility of IPv6 based networks for the aviation needs of the United States. In Europe, the Eurocontrol lead, Internet Protocol for Aviation Exchange (iPAX) Working Group is actively investigating the various ways of migrating the aviation authorities backbone infrastructure from X.25 based networks to an IPv6 based network. For the last 15 years, the global aviation community has pursued the development and implementation of an industry-specific set of communications standards known as the Aeronautical Telecommunications Network (ATN). These standards are now beginning to affect the emerging military Global Air Traffic Management (GATM) community as well as the commercial air transport community. Efforts are continuing to gain a full understanding of the differences and similarities between ATN and Internet architectures as related to Communications, Navigation, and Surveillance (CNS) infrastructure choices. This research paper describes the implementation of the IPv6 test bed at NASA GRC, and Computer Networks & Software, Inc. and these two test beds are interface to Eurocontrol over the IPv4 Internet. This research work looks into the possibility of providing QoS performance for Aviation application in an IPv6 network as is provided in an ATN based network. The test bed consists of three autonomous systems. The autonomous system represents CNS domain, NASA domain and a EUROCONTROL domain. The primary mode of connection between CNS IPv6 testbed and NASA and EUROCONTROL IPv6 testbed is initially a set of IPv6 over IPv4 tunnels. The aviation application under test (CPDLC) consists of two processes running on different IPv6 enabled machines.

    Wilson, William C.; Atkinson, Gary M.

    2013-01-01

    NASA aeronautical programs require rigorous ground and flight testing. Many of the testing environments can be extremely harsh. These environments include cryogenic temperatures and high temperatures (greater than 1500 C). Temperature, pressure, vibration, ionizing radiation, and chemical exposure may all be part of the harsh environment found in testing. This paper presents a survey of research opportunities for universities and industry to develop new wireless sensors that address anticipated structural health monitoring (SHM) and testing needs for aeronautical vehicles. Potential applications of passive wireless sensors for ground testing and high altitude aircraft operations are presented. Some of the challenges and issues of the technology are also presented.

    Lehr, William H.; Pupillo, Lorenzo Maria

    The Internet is now widely regarded as essential infrastructure for our global economy and society. It is in our homes and businesses. We use it to communicate and socialize, for research, and as a platform for E-commerce. In the late 1990s, much was predicted about what the Internet has become at present; but now, we have actual experience living with the Internet as a critical component of our everyday lives. Although the Internet has already had profound effects, there is much we have yet to realize. The present volume represents a third installment in a collaborative effort to highlight the all-encompassing, multidisciplinary implications of the Internet for public policy. The first installment was conceived in 1998, when we initiated plans to organize an international conference among academic, industry, and government officials to discuss the growing policy agenda posed by the Internet. The conference was hosted by the European Commission in Brussels in 1999 and brought together a diverse mix of perspectives on what the pressing policy issues would be confronting the Internet. All of the concerns identified remain with us today, including how to address the Digital Divide, how to modify intellectual property laws to accommodate the new realities of the Internet, what to do about Internet governance and name-space management, and how to evolve broadcast and telecommunications regulatory frameworks for a converged world.

    2012-01-01

    Internet addiction is defined as uncontrolled and harmful use of Internet, which manifests in three forms: gaming, various sexual activities and excessive use of emails, chats or SMS messaging. Several studies have found that abuse of alcohol and other substances, depression and other health problems are associated with Internet addiction. In boys and men depression may be more a consequence of the addiction than a cause for it. ADHD seems to be a significant background factor for developing the condition. Because it is almost impossible to lead a life without Internet and computers nowadays, it is unrealistic to aim towards full abstinence. Treatment has generally followed the guidelines adapted for pathological gambling.

  5. Ensuring US National Aeronautics Test Capabilities

    Marshall, Timothy J.

    2010-01-01

    U.S. leadership in aeronautics depends on ready access to technologically advanced, efficient, and affordable aeronautics test capabilities. These systems include major wind tunnels and propulsion test facilities and flight test capabilities. The federal government owns the majority of the major aeronautics test capabilities in the United States, primarily through the National Aeronautics and Space Administration (NASA) and the Department of Defense (DoD). However, changes in the Aerospace landscape, primarily the decrease in demand for testing over the last 20 years required an overarching strategy for management of these national assets. Therefore, NASA established the Aeronautics Test Program (ATP) as a two-pronged strategic initiative to: (1) retain and invest in NASA aeronautics test capabilities considered strategically important to the agency and the nation, and (2) establish a strong, high level partnership with the DoD. Test facility utilization is a critical factor for ATP because it relies on user occupancy fees to recover a substantial part of the operations costs for its facilities. Decreasing utilization is an indicator of excess capacity and in some cases low-risk redundancy (i.e., several facilities with basically the same capability and overall low utilization). However, low utilization does not necessarily translate to lack of strategic importance. Some facilities with relatively low utilization are nonetheless vitally important because of the unique nature of the capability and the foreseeable aeronautics testing needs. Unfortunately, since its inception, the customer base for ATP has continued to shrink. Utilization of ATP wind tunnels has declined by more than 50% from the FY 2006 levels. This significant decrease in customer usage is attributable to several factors, including the overall decline in new programs and projects in the aerospace sector; the impact of computational fluid dynamics (CFD) on the design, development, and research

    Full Text Available Civil aviation is developing rapidly, and the number of domestic and international operations is increasing exponentially every year than the previous one. Airline companies with increased air traffic and the number of passengers increase the demand of new aircrafts. An aircraft needs not only fuel but also pilot and aeronautical information (charts, digital navigation information, flight plan, and etc. to perform flight operation. One of the most important components in aeronautical information is the terminal chart. Authorized institution in every state is responsible to publish their terminal charts for certain periods. Although these charts are produced in accordance with ICAO’s Annex 4 and Annex 15, cartographic representation and page layout differs in each state’s publication. This situation makes difficult to read them by pilots. In this paper, standard instrument departure (SID charts are analysed to produce by use of cutting-edge and competitive technologies instead of classical computer-aided drawing and vector based graphic applications that are currently used by main chart producers. The goal is to design efficient and commercial chart management system that is able to produce aeronautical charts with same cartographic representation for all states.

  14. MAP3K8 (TPL2/COT affects obesity-induced adipose tissue inflammation without systemic effects in humans and in mice.

    Directory of Open Access Journals (Sweden)

    Dov B Ballak

    Full Text Available Chronic low-grade inflammation in adipose tissue often accompanies obesity, leading to insulin resistance and increasing the risk for metabolic diseases. MAP3K8 (TPL2/COT is an important signal transductor and activator of pro-inflammatory pathways that has been linked to obesity-induced adipose tissue inflammation. We used human adipose tissue biopsies to study the relationship of MAP3K8 expression with markers of obesity and expression of pro-inflammatory cytokines (IL-1β, IL-6 and IL-8. Moreover, we evaluated obesity-induced adipose tissue inflammation and insulin resistance in mice lacking MAP3K8 and WT mice on a high-fat diet (HFD for 16 weeks. Individuals with a BMI >30 displayed a higher mRNA expression of MAP3K8 in adipose tissue compared to individuals with a normal BMI. Additionally, high mRNA expression levels of IL-1β, IL-6 and IL-8, but not TNF -α, in human adipose tissue were associated with higher expression of MAP3K8. Moreover, high plasma SAA and CRP did not associate with increased MAP3K8 expression in adipose tissue. Similarly, no association was found for MAP3K8 expression with plasma insulin or glucose levels. Mice lacking MAP3K8 had similar bodyweight gain as WT mice, yet displayed lower mRNA expression levels of IL-1β, IL-6 and CXCL1 in adipose tissue in response to the HFD as compared to WT animals. However, MAP3K8 deficient mice were not protected against HFD-induced adipose tissue macrophage infiltration or the development of insulin resistance. Together, the data in both human and mouse show that MAP3K8 is involved in local adipose tissue inflammation, specifically for IL-1β and its responsive cytokines IL-6 and IL-8, but does not seem to have systemic effects on insulin resistance.

    Morris, A. Terry; Goode, Plesent W.

    2002-01-01

    The future Communication, Navigation, and Surveillance/Air Traffic Management (CNS/ATM) System will rely on global satellite navigation, and ground-based and satellite based communications via Multi-Protocol Networks (e.g. combined Aeronautical Telecommunications Network (ATN)/Internet Protocol (IP)) to bring about needed improvements in efficiency and safety of operations to meet increasing levels of air traffic. This paper will discuss the development of an approach that completely describes optimal data link architecture configuration and behavior to meet the multiple conflicting objectives of concurrent and different operations functions. The practical application of the approach enables the design and assessment of configurations relative to airspace operations phases. The approach includes a formal taxonomic classification, an architectural analysis methodology, and optimization techniques. The formal taxonomic classification provides a multidimensional correlation of data link performance with data link service, information protocol, spectrum, and technology mode; and to flight operations phase and environment. The architectural analysis methodology assesses the impact of a specific architecture configuration and behavior on the local ATM system performance. Deterministic and stochastic optimization techniques maximize architectural design effectiveness while addressing operational, technology, and policy constraints.

    Aeronautical information is an important type of geospatial data to ensure the safety and efficiency for air traffic. Currently, aeronautical information service (AIS) pro- vide these data to users by the medium of aeronautical chart, aeronautical information pub- lic (AIP), notice to airman (NOTA M), and so on. We are in the age of the Internet, sat- ellite navigation and computer networks, yet our approach to aeronautical geospatial data distribution is still based on paper charts, paper documentation and telex-based text mes- sages. Systems exist in isolation. Many of the data is entered more than twice in different computers using a keyboard rather than via file transfer or database transactions. To satisfy new requirements for the Global Air Traffic Management Operational Con- cept, aeronautical information services should be transferred to support a digital, real- time, accredited and secure aeronautical information environment. As an open geospatial data standard, GML gives aeronautical information feature coding method and interchan- ging format. Much has been done in air traffic community, and the technology has become more mature and is widely used. EUROCONTROL and FAA have developed AIXM (Aeronautical Information Exchange Model) based on GML. In Europe, the European AIS Database (EAD) provide unique reference database of aeronautical information on be- half of AIXM. In Chinese air traffic community, unique aeronautical geospatial data model has been considered as the key to ensure quality, integrity and interoperation of the aeronautical in- formation. But there is littlematerial progress on the data modeling. Based on studies on the characteristic of aeronautical information, the paper analyzed the mapping aeronautical data between and GML. Taking the basic aeronautical information database in Airline Management System as an example, an aeronautical geographic data model has been brought forward in this paper. Studies have shown that

    2012-08-01

    In many innovative science content professional development (PD) courses for teachers, science concepts are situated within pedagogical contexts, or in other words, science content is incorporated within contexts relevant to teaching and student learning. Pedagogical contexts are often used because they are believed to be engaging for teachers and to support content transfer to the classroom. However, few studies have investigated how pedagogical contexts serve to impact teacher engagement and science content learning. This qualitative case study examined K-8 in-service teachers' interactions with pedagogical contexts in a chemistry PD course. Findings indicate that teachers': (1) contribution of teaching experiences helped create a collegial learning environment, (2) sharing of concerns from classroom teaching directed content discussion and learning objectives, and (3) reflection on teacher and learner roles in the PD classroom led to persistence in chemistry-content learning. Implications for PD instructor use of pedagogical contexts in science content based PD are discussed.

    Full Text Available Current health education and physical fitness programs have failed to prevent the youth obesity epidemic. The diminishing emphasis placed on such programs due to curricular and budgetary constraints results in few opportunities to promote students’ active participation in regular physical activity and health education programs. Findings indicate that a successful program to promote healthy nutrition, an active lifestyle, and regular physical exercise requires that the information is easily accessible, and presented in a clear and concise format. Readers are introduced to a comprehensive program, easily adjustable throughout the K-8 curriculum. It is designed to complement regular classroom activities by introducing a series of stand-alone lessons and activities to educate students on the benefits of regular exercise and healthy lifestyle.

    We measured the phonon dispersion at ambient conditions in single-crystal type-I clathrate K8Zn4Sn42, a material with promising thermoelectric properties that has only recently been synthesized, using the high-energy resolution inelastic X-ray scattering (IXS) technique. From the sound velocities along high-symmetry directions, we extracted the elastic constants (C 11, C 12, C 44 = 63.2, 19.1, 21.9 GPa, respectively). Experimental results agree with the predictions from first-principles calculations on the hypothetical, "guest-free", type-I clathrate Sn46. The size of the crystal investigated was several orders of magnitude smaller than what is required for neutron and ultrasonic measurements. Due to this essential property, together with the high-energy resolution, high-momentum-transfer resolution, and the access to the strongest Bragg reflections, IXS is the technique of choice for measuring the full elastic constant tensor for microcrystals.

  20. A Novel Onboard-gateway-based Mechanism to Improve TCP Performance in Aeronautical Satellite Networks

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The IP-based networks on aircraft serve to support Internet services via satellites. However, in aeronautical satellite hybrid networks, the TCP protocol performance often deteriorates due to improper decreases and slow recovery of the congestion window. This paper proposes a window size determination and notification mechanism, onboard-gateway-based mechanism (OGBM), which is based on the onboard gateway in the networks on aircraft. A cross-layer approach is adopted by the onboard gateway to obtain the satellite link bandwidth information. And then, by the gateway, through changing the receiver's advertised window field in ACK packets, TCP sources are notified of the window size of each TCP source calculated on the ground of bandwidth delay product and flow numbers. The mechanism is able to avoid improper changes of TCP window and serve multiple users. Simulation results show that the mechanism with the fairness index close to 1 improves TCP performance in aeronautical satellite networks.

    1953-07-01

    Full Text Available The progress in aeronautics in the United Kingdom from 1903 to the present-day has been traced. The advance in design could be traced partly to the steady improvement in techniques such as strength of materials, structural methods, aerodynamics and engine design, and partly to definite technical discontinuities such as the introduction of the unbraced monoplane and later of the jet turbine. The key to this progress has been the large investment made in science and technical research and the healthy integration between industrial enterprise and government planning.

  14. Internet Sexualities

    Science.gov (United States)

    Döring, Nicola

    The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

    Full Text Available Three-dimensional (3D textile structures with better delamination resistance and damage impact tolerance to be applied in composites for structural components is one of the main goals of the aeronautical industry. Textile Research Centre in Canet de Mar has been working since 2008 in this field. Our staff has been designing, developing and producing different textile structures using different production methods and machinery to improve three-dimensional textile structures as fiber reinforcement for composites. This paper describes different tests done in our textile labs from unidirectional structures to woven, knitted or braided 3 D textile structures. Advantages and disadvantages of each textile structure are summarized. The second part of this paper deals with our know-how in the manufacturing and assessing of three-dimensional textile structures during this last five years in the field of textile structures for composites but also in the development of structures for other applications. In the field of composites for aeronautic sector we have developed textile structures using the main methods of textile production, that is to say, weaving, warp knitting, weft knitting and braiding. Comparing the advantages and disadvantages it could be said that braided fabrics, with a structure in the three space axes are the most suitable for fittings and frames.

    Internet technologies have made a rapid progress, bringing convenience to daily life. On the other hand, internet use disorder and internet addiction (IA) have become reportedly serious health and social problems. In 2013, internet gaming disorder criteria have been proposed in the section of Conditions for Further Study of DSM-5. Existing epidemiological studies by questionnaire methods have reported that the prevalence of IA ranges between 2.8% and 9.9% among youths in Japan. Attention deficit hyperactivity disorder (ADHD), sleeping disorders, depression, obsessive compulsive disorder, and phobic anxiety disorder are extremely common comorbid mental disorders with IA. Some psychotherapies (e.g., cognitive behavioral therapy, motivational interviewing) and medical treatments (e.g., antidepressant drugs, methylphenidate) for comorbid mental disorders as well as rehabilitation (e.g., treatment camp) are effective for IA remission. However, some serious cases of IA may be difficult to treat, and prevention is very important. In future, the prevention, rehabilitations and treatments for IA will be more required in Japan.

  1. Plakophilin3 loss leads to an increase in PRL3 levels promoting K8 dephosphorylation, which is required for transformation and metastasis.

    Directory of Open Access Journals (Sweden)

    Nileema Khapare

    Full Text Available The desmosome anchors keratin filaments in epithelial cells leading to the formation of a tissue wide IF network. Loss of the desmosomal plaque protein plakophilin3 (PKP3 in HCT116 cells, leads to an increase in neoplastic progression and metastasis, which was accompanied by an increase in K8 levels. The increase in levels was due to an increase in the protein levels of the Phosphatase of Regenerating Liver 3 (PRL3, which results in a decrease in phosphorylation on K8. The increase in PRL3 and K8 protein levels could be reversed by introduction of an shRNA resistant PKP3 cDNA. Inhibition of K8 expression in the PKP3 knockdown clone S10, led to a decrease in cell migration and lamellipodia formation. Further, the K8 PKP3 double knockdown clones showed a decrease in colony formation in soft agar and decreased tumorigenesis and metastasis in nude mice. These results suggest that a stabilisation of K8 filaments leading to an increase in migration and transformation may be one mechanism by which PKP3 loss leads to tumor progression and metastasis.

    Full Text Available It has now become quite obvious that the Internet has brought significant changes to our society and a break on how we lived before its emergence. It is still too early to assess the impact on society of the new services at our disposal, such as the capacity to communicate faster and cheaper on a global scale, access information and, perhaps more importantly, to produce and disseminate information in a way that is accessible to all.It is clear that the advent of the Information Society implies changes in our society that constitute a point of no return. However, contrary to what happened when we entered the Industrial Age about three centuries ago, when the changing process was slow and led by older individuals, these days the entrance into the Information Society is taking place rapidly and the decisive players are younger people. The global nature of the Internet, the possibility of producing and distributing any type of content in digital form at almost zero cost, as well as the vast number of people who use the web, have highlighted the need for new forms of intervention in a sector where there are many types of players. It is in this context that the problem of Internet Governance becomes a very current issue, inasmuch as one feels the need to guarantee a diversity of rights and duties, which may appear difficult to reconcile.This paper presents a brief overview of the main players and initiatives which, in the field of Internet Governance, have tried to contribute to turning this network into a factor for social development and democraticity on a global scale.

    The World Wide Web and the Internet are rapidly expanding spaces, of great economic and social significance, which offer an opportunity to study many phenomena, often previously inaccessible, on an unprecedented scale and resolution with relative ease. These phenomena are measurable on the scale of tens of millions of users and hundreds of millions of pages. By virtue of nearly complete electronic mediation, it is possible in principle to observe the time and ``spatial'' evolution of nearly all choices and interactions. This cyber-space therefore provides a view into a number of traditional research questions (from many academic disciplines) and creates its own new phenomena accessible for study. Despite its largely self-organized and dynamic nature, a number of robust quantitative regularities are found in the aggregate statistics of interesting and useful quantities. These regularities can be understood with the help of models that draw on ideas from statistical physics as well as other fields such as economics, psychology and decision theory. This thesis develops models that can account for regularities found in the statistics of Internet congestion and user surfing patterns and discusses some practical consequences. practical consequences.

    The Planetary Science Institute (PSI), in partnership with the Tucson Regional Science Center, offers a series of professional development workshops targeting K-8 science teachers in southern Arizona. Using NASA data sets, research results, and a team of PSI scientists and educators, our workshops provide teachers with in-depth content knowledge of fundamental concepts in astronomy, geology, and planetary science. Current workshops are: The Earth-Moon System, Exploring the Terrestrial Planets, Impact Cratering, The Asteroid-Meteorite Connection, Volcanoes of the Solar System, Deserts of the Solar System, and Astrobiology and the Search for Extrasolar Planets. Several workshops incorporate customized computer visualizations developed at PSI. These visualizations are designed to help teachers overcome the common misconceptions students have in fundamental areas of space science. For example, the simple geometric relationship between the sun, the moon, and Earth is a concept that is rife with misconceptions. How can the arrangement of these objects account for the constantly changing phases of the moon as well as the occasional eclipses of the sun and moon? Students at all levels often struggle to understand the explanation for phases and eclipses even after repeated instruction over many years. Traditional classroom techniques have proven to be insufficient at rooting out entrenched misconceptions. One problem stems from the difficulty of developing an accurate mental picture of the Earth-Moon system in space when a student's perspective has always been firmly planted on the ground. To address this problem our visualizations take the viewers on a journey beyond Earth, giving them a so-called "god's eye" view of how the Earth-Moon system would look from a distance. To make this journey as realistic as possible we use ray-tracing software, incorporate NASA mission images, and accurately portray rotational and orbital motion. During a workshop our visualizations are

    2016-07-01

    Full Text Available For a further understanding of the phase transitions mechanism in type-I silicon clathrates K8Si46, ab initio self-consistent electronic calculations combined with linear-response method have been performed to investigate the vibrational properties of alkali metal K atoms encapsulated type-I silicon-clathrate under pressure within the framework of density functional perturbation theory. Our lattice dynamics simulation results showed that the pressure induced phase transition of K8Si46 was believed to be driven by the phonon instability of the calthrate lattice. Analysis of the evolution of the partial phonon density of state with pressure, a legible dynamic picture for both guest K atoms and host lattice, was given. In addition, based on phonon calculations and combined with quasi-harmonic approximation, the specific heat of K8Si46 was derived, which agreed very well with experimental results. Also, other important thermal properties including the thermal expansion coefficients and Grüneisen parameters of K8Si46 under different temperature and pressure were also predicted.

    Rapid growth in air travel has been projected to continue for the foreseeable future. To maintain a safe and efficient national and global aviation system, significant advances in communications systems supporting aviation are required. Satellites will increasingly play a critical role in the aeronautical communications network. At the same time, current ground-based communications links, primarily very high frequency (VHF), will continue to be employed due to cost advantages and legacy issues. Hence a hybrid satellite-terrestrial network, or group of networks, will emerge. The increased complexity of future aeronautical communications networks dictates that system-level modeling be employed to obtain an optimal system fulfilling a majority of user needs. The NASA Glenn Research Center is investigating the current and potential future state of aeronautical communications, and is developing a simulation and modeling program to research future communications architectures for national and global aeronautical needs. This paper describes the primary requirements, the current infrastructure, and emerging trends of aeronautical communications, including a growing role for satellite communications. The need for a hybrid communications system architecture approach including both satellite and ground-based communications links is explained. Future aeronautical communication network topologies and key issues in simulation and modeling of future aeronautical communications systems are described.

    U.S. leadership in aeronautics depends on ready access to technologically advanced, efficient, and affordable aeronautics test capabilities. These systems include major wind tunnels and propulsion test facilities and flight test capabilities. The federal government owns the majority of the major aeronautics test capabilities in the United States, primarily through the National Aeronautics and Space Administration (NASA) and the Department of Defense (DoD), however an overarching strategy for management of these national assets was needed. Therefore, in Fiscal Year (FY) 2006 NASA established the Aeronautics Test Program (ATP) as a two-pronged strategic initiative to: (1) retain and invest in NASA aeronautics test capabilities considered strategically important to the agency and the nation, and (2) establish a strong, high level partnership with the DoD Test Resources Management Center (TRMC), stewards of the DoD test and evaluation infrastructure. Since then, approximately seventy percent of the ATP budget has been directed to underpin fixed and variable costs of facility operations within its portfolio and the balance towards strategic investments in its test facilities, including maintenance and capability upgrades. Also, a strong guiding coalition was established through the National Partnership for Aeronautics Testing (NPAT), with governance by the senior leadership of NASA s Aeronautics Research Mission Directorate (ARMD) and the DoD's TRMC. As part of its strategic planning, ATP has performed or participated in many studies and analyses, including assessments of major NASA and DoD aeronautics test capabilities, test facility condition evaluations and market research. The ATP strategy has also benefitted from unpublished RAND research and analysis by Ant n et al. (2009). Together, these various studies, reports and assessments serve as a foundation for a new, five year strategic plan that will guide ATP through FY 2014. Our vision for the future is a balanced

  9. Involvement of MAP3K8 and miR-17-5p in poor virologic response to interferon-based combination therapy for chronic hepatitis C.

    Directory of Open Access Journals (Sweden)

    Akihito Tsubota

    Full Text Available Despite advances in chronic hepatitis C treatment, a proportion of patients respond poorly to treatment. This study aimed to explore hepatic mRNA and microRNA signatures involved in hepatitis C treatment resistance. Global hepatic mRNA and microRNA expression profiles were compared using microarray data between treatment responses. Quantitative real-time polymerase chain reaction validated the gene signatures from 130 patients who were infected with hepatitis C virus genotype 1b and treated with pegylated interferon-alpha and ribavirin combination therapy. The correlation between mRNA and microRNA was evaluated using in silico analysis and in vitro siRNA and microRNA inhibition/overexpression experiments. Multivariate regression analysis identified that the independent variables IL28B SNP rs8099917, hsa-miR-122-5p, hsa-miR-17-5p, and MAP3K8 were significantly associated with a poor virologic response. MAP3K8 and miR-17-5p expression were inversely correlated with treatment response. Furthermore, miR-17-5p repressed HCV production by targeting MAP3K8. Collectively, the data suggest that several molecules and the inverse correlation between mRNA and microRNA contributed to a host genetic refractory hepatitis C treatment response.

    2016-07-01

    Full Text Available The paper presents the concept of a method ensuring quality of aeronautical data. European Union (among others UE 73/2010 as well as international (among others ICAO Annex 15 regulations introduce a number of requirements regarding the quality and safety of aeronautical data. Those directives set up a complementary regulations system. However with their objective and scope they determine mainly the specifications and requirements that are to be implemented and compatible. Mentioned regulations also refer to selected international standards (e.g. ISO 19157, focused on quality and safety of geographic data and information. Nevertheless within the scope of considered regulations and norms no algorithms and methods of ensuring required quality in the process of aeronautical data collection and processing were determined. Taking into account the identified needs, authors proposed the application of statistical method for process quality management – six-sigma.

    This paper describes the automation of one class of aeronautical design activity using artificial intelligence and advanced software techniques. Its purpose is to suggest concepts, terminology, and approaches that may be useful in enhancing design automation. By understanding the basic concepts and tasks in design, and the technologies that are available, it will be possible to produce, in the future, systems whose capabilities far exceed those of today's methods. Some of the tasks that will be discussed have already been automated and are in production use, resulting in significant productivity benefits. The concepts and techniques discussed are applicable to all design activity, though aeronautical applications are specifically presented.

    2002-10-01

    Full Text Available We previously reported that anthracyclines, which could generate reactive oxygen species (ROS, could induce the urokinase-type plasminogen activator (uPA gene expression in human RC-K8 malignant lymphoma cells and in H69 small cell lung cancer (SCLC cells. In screening other uPA-inducible anti-cancer agents, we found that camptothecin (CPT and its derivative, SN38, could induce uPA in RC-K8 and H69 cells. CPT and SN38, which are also used for the treatment of lymphoma and SCLC, significantly increased the uPA accumulation in the conditioned media of both cells in a dose-dependent manner. The maximum induction of uPA mRNA levels was observed 24 h after stimulation. Pretreatment with pyrrolidine dithiocarbamate (PDTC, an anti-oxidant, inhibited the CPT-induced uPA mRNA expression. Thus, CPT induces uPA through gene expression, and, therefore, CPT may influence the tumor-cell biology by up-regulating the uPA/plasmin system.

    Madsen, J.; Allen, D.; Donham, R.; Fifield, S.; Ford, D.; Shipman, H.; Dagher, Z.

    2007-12-01

    University of Delaware faculty in the geological sciences, biological sciences, and the physics and astronomy departments have partnered with faculty and researchers from the school of education to form a continuum for K- 8 pre-service teacher preparation in science. The goal of the continuum is to develop integrated understandings of content and pedagogy so that these future teachers can effectively use inquiry-based approaches in teaching science in their classrooms. Throughout the continuum where earth science content appears an earth system science approach, with emphasis on inquiry-based activities, is employed. The continuum for K-8 pre-service teachers includes a gateway content course in the earth, life, or physical sciences taken during the freshman year followed by integrated science content and methods courses taken during the sophomore year. These integrated courses, called the Science Semester, were designed and implemented with funding from the National Science Foundation. During the Science Semester, traditional content and pedagogy subject matter boundaries are crossed to stress shared themes that teachers must understand to teach standards-based science. Students work collaboratively on multidisciplinary problem-based learning (PBL) activities that place science concepts in authentic contexts and build learning skills. They also critically explore the theory and practice of elementary science teaching, drawing on their shared experiences of inquiry learning during the Science Semester. The PBL activities that are the hallmark of the Science Semester provide the backdrop through which fundamental earth system interactions can be studied. For example in a PBL investigation that focuses on kids, cancer, and the environment, the hydrologic cycle with emphasis on surface runoff and ground water contamination is studied. Those students seeking secondary certification in science will enroll, as a bridge toward their student teaching experience, in an

    Wang, Yujing; Gao, Xueqiang; Wang, Mei

    2007-11-01

    According to the designed characteristics and demands of aeronautic image compression system, lifting scheme wavelet and SPIHT algorithm was selected as the key part of software implementation, which was introduced with details. In order to improve execution efficiency, border processing was simplified reasonably and SPIHT (Set Partitioning in Hierarchical Trees) algorithm was also modified partly. The results showed that the selected scheme has a 0.4dB improvement in PSNR(peak-peak-ratio) compared with classical Shaprio's scheme. To improve the operating speed, the hardware system was then designed based on DSP and many optimization measures were then applied successfully. Practical test showed that the system can meet the real-time demand with good quality of reconstruct image, which has been used in an aeronautic image compression system practically.

  19. Differential psychological impact of internet exposure on Internet addicts.

    Directory of Open Access Journals (Sweden)

    Michela Romano

    Full Text Available The study explored the immediate impact of internet exposure on the mood and psychological states of internet addicts and low internet-users. Participants were given a battery of psychological tests to explore levels of internet addiction, mood, anxiety, depression, schizotypy, and autism traits. They were then given exposure to the internet for 15 min, and re-tested for mood and current anxiety. Internet addiction was associated with long-standing depression, impulsive nonconformity, and autism traits. High internet-users also showed a pronounced decrease in mood following internet use compared to the low internet-users. The immediate negative impact of exposure to the internet on the mood of internet addicts may contribute to increased usage by those individuals attempting to reduce their low mood by re-engaging rapidly in internet use.

    The Internet is a very powerful and inexpensive tool that was created for the free distribution of knowledge and information. The Internet is a learning tool, a research tool, a virtual library without borders and membership requirements, a journal with instant publication, a help desk, and a newspaper/journal with current information. Very soon, when live audio and video transmission is perfected, the Internet also will be a live classroom and everyday conference. Forensic scientists, laboratories and colleges should make use of information already available on the Internet. They also should actively participate and contribute. Very few forensic scientists and laboratories have made their presence felt by setting up their home pages/web pages. But, there is tremendous growth during the past year. Immense benefits from Internet to forensic community are discussed along with the author's personal experience. Creating on-line searchable data bases in all specialties of forensic science is an urgent need. Leading forensic journals should take a lead and create on-line searchable indexes with abstracts. On line electronic publishing, collaborative research/paper publishing or editing is easy, fast, economical and convenient through the use of the Internet. Creation of Internet repositories of unpublished papers is an idea worth looking into. Internet also can be used to give training, re-training or advanced training to students/forensic scientists.

    2003-05-01

    Leucaena leucocephala var. K-8 is a fast-growing, tropical leguminous tree that has multiple economic uses. This study was conducted to evaluate the effect(s) of varying NaCl concentrations on growth, N(2) fixation, and percentage of total tissue nitrogen in different organs in L. leucocephala. Seeds were germinated and grown for 10 wk with a nitrogen-free fertilizer applied every 2 wk. At 10 wk, plants were treated for either 0, 7, 14, 21, or 28 wk with either deionized water (control), 0.00625 mol/L, 0.0125 mol/L, 0.025 mol/L, 0.05 mol/L, or 0.1 mol/L NaCl in addition to the fertilizer every 2 wk. Growth was measured as plant height, nodule number and mass, and dry tissue mass. N(2) fixation was measured by the acetylene reduction assay. Percentage of tissue nitrogen was determined using Kjeldahl analysis. In younger plants (7-wk treatment), major fluctuations in NaCl tolerance were observed in the different plant organs. As plants matured (14- and 21-wk treatment) NaCl concentrations of 0.025 mol/L and higher caused the greatest reduction in growth and tissue nitrogen. We conclude that NaCl concentrations of 0.025 mol/L and greater caused a major decrease in growth, N(2) fixation, and percentage of tissue nitrogen in L. leucocephala plants that were less than 1 yr old.

    1998-01-01

    The aerospace industry is being challenged to reduce costs and development time as well as utilize new technologies to improve product performance. Information technology (IT) is the key to providing revolutionary solutions to the challenges posed by the increasing complexity of NASA's aeronautics and space missions and the sophisticated nature of the systems that enable them. The NASA Ames vision is to develop technologies enabling the information age, expanding the frontiers of knowledge for aeronautics and space, improving America's competitive position, and inspiring future generations. Ames' missions to accomplish that vision include: 1) performing research to support the American aviation community through the unique integration of computation, experimentation, simulation and flight testing, 2) studying the health of our planet, understanding living systems in space and the origins of the universe, developing technologies for space flight, and 3) to research, develop and deliver information technologies and applications. Information technology may be defined as the use of advance computing systems to generate data, analyze data, transform data into knowledge and to use as an aid in the decision-making process. The knowledge from transformed data can be displayed in visual, virtual and multimedia environments. The decision-making process can be fully autonomous or aided by a cognitive processes, i.e., computational aids designed to leverage human capacities. IT Systems can learn as they go, developing the capability to make decisions or aid the decision making process on the basis of experiences gained using limited data inputs. In the future, information systems will be used to aid space mission synthesis, virtual aerospace system design, aid damaged aircraft during landing, perform robotic surgery, and monitor the health and status of spacecraft and planetary probes.

    Arc tracking tests have been carried out between two voluntarily damaged aeronautic cables. Copper or aluminum conductors have been exposed to short circuits under alternating current. Various data have been recorded (arc voltage and current, radiated power and ablated mass), enabling to determine a power balance, in which every contribution is estimated. The total power is mainly transferred to the cables (between 50 and 65%, depending on the current and the cable type), and causes the melting and partial vaporization of the metallic core and insulating material, or is conducted or radiated. The other part is deposited into the arc column, being either radiated, convected or conducted.

    The Internet provides adults and children with a medium for professional and personal communication throughout the world. As widespread communication in cyberspace grows exponentially, the potential for Internet-related crimes, such as cyberstalkng, has accelerated. Children are particularly vulnerable to sexual predators, such as pedophiles, on the Internet. This article reports cases of pedophiles who used the information superhighway to exploit child victims. Two models of pedophilia on the Internet are discussed: a trust-based seductive model and a direct sexual model. This article explores the role that mental health professionals may play in the assessment of Internet pedophilia. For example, mental health professionals may provide psychiatric treatment to victims of Internet pedophiles. Psychiatrists may be involved in the evaluation of perpetrators of Internet crimes in a clinical or forensic setting. Governmental agencies, the criminal justice system, school, or the media may request consultations by mental health professionals as part of a multi-disciplinary approach to prevention. Methods of government intervention are discussed.

  14. Hybrid internet access

    1995-01-01

    Access to the Internet is either too slow (dial-up SLIP) or too expensive (switched 56 kbps, frame relay) for the home user or small enterprise. The Center for Satellite and Hybrid Communication Networks and Hughes Network Systems have collaborated using systems integration principles to develop a prototype of a low-cost hybrid (dial-up and satellite) newtork terminal which can deliver data from the Internet to the user at rates up to 160 kbps. An asymmetric TCP/IP connection is used breaking the network link into two physical channels: a terrestrial dial-up for carrying data from the terminal into the Internet and a receive-only satellite link carrying IP packets from the Internet to the user. With a goal of supporting bandwidth hungry Internet applications such as Mosaic, Gopher, and FTP, this system has been designed to support any Intel 80386/486 PC, any commercial TCP/IP package, any unmodified host on the Internet, and any of the routers, etc., within the Internet. The design exploits the following three observations: 1) satellites are able to offer high bandwidth connections to a large geographical area, 2) a receive-only VSAT is cheap to manufacture and easier to install than one which can also transmit, and 3) most computer users, especially those in a home environment, will want to consume much more information than they generate. IP encapsulation, or tunneling, issued to manipulate the TCP/IP protocols to route packets asymmetrically.

    Full Text Available This paper will address the rumors and the Internet in two ways: rumors as the subject of the Internet and the Internet as a channel of dissemination of rumors. We define rumors in a broadly way as an unverified information circulating within a social group. In a strict sense, rumors can be understand as false information that people believe. A rumor is an urban myth, a legend, a hoax, or a contemporary narrative, a tale of everyday life, false or dubious, but in which we believed because it is likely, and it conveys a moral message.

  3. Interference Analysis for an Aeronautical Mobile Airport Communications System

    Science.gov (United States)

    Wilson, Jeffrey D.; Kercewski, Robert J.

    2010-01-01

    The next generation of aeronautical communications for airport surface applications has been identified through a NASA research program and an international collaborative future communications study. The result, endorsed by both the United States and European regulatory agencies is called AeroMACS (Aeronautical Mobile Airport Communications System) and is based upon the IEEE 802.16e mobile wireless standard. Coordinated efforts to develop appropriate aviation standards for the AeroMACS system are now underway within RTCA (United States) and Eurocae (Europe). AeroMACS will be implemented in a recently allocated frequency band, 5091- 5150 MHz. As this band is also occupied by fixed satellite service uplinks, AeroMACS must be designed to avoid interference with this incumbent service. The aspects of AeroMACS operation that present potential interference to the fixed satellite service are under analysis in order to enable the definition of standards that assure that such interference will be avoided. The NASA Glenn Research Center has been involved in this analysis, and the first results of modeling and simulation efforts directed at this analysis are the subject of this paper.12

  4. Aeronautical satellite antenna steering using magnetic field sensors

    Science.gov (United States)

    Sydor, John; Dufour, Martial

    1993-01-01

    Designers of aeronautical satellite terminals are often faced with the problem of steering a directive antenna from an airplane or helicopter. This problem is usually solved by using aircraft orientation information derived from inertial sensors on-board the aircraft in combination with satellite ephemeris information calculated from geographic coordinates. This procedure works well but relies heavily on avionics that are external to the terminal. For the majority of small aircraft and helicopters which will form the bulk of future aeronautical satcom users, such avionics either do not exist or are difficult for the satellite terminal to interface with. At the Communications Research Center (CRC), work has been undertaken to develop techniques that use the geomagnetic field and satellite antenna pointing vectors (both of which are stationary in a local geographical area) to track the position of a satellite relative to a moving platform such as an aircraft. The performance of this technique is examined and a mathematical steering transformation is developed within this paper. Details are given regarding the experimental program that will be undertaken to test the concepts proposed herein.

    Lad, Mohit; Massey, Dan; Zhang, Lixia

    2006-01-01

    Today's Internet provides a global data delivery service to millions of end users and routing protocols play a critical role in this service. It is important to be able to identify and diagnose any problems occurring in Internet routing. However, the Internet's sheer size makes this task difficult. One cannot easily extract out the most important or relevant routing information from the large amounts of data collected from multiple routers. To tackle this problem, we have developed Link-Rank, a tool to visualize Internet routing changes at the global scale. Link-Rank weighs links in a topological graph by the number of routes carried over each link and visually captures changes in link weights in the form of a topological graph with adjustable size. Using Link-Rank, network operators can easily observe important routing changes from massive amounts of routing data, discover otherwise unnoticed routing problems, understand the impact of topological events, and infer root causes of observed routing changes.

    Connecting ionosondes to the Internet gives easy access to real-time information on ionospheric conditions. Some of the ionosonde sites provide just the ionogram displays, others give in addition the scaled ionospheric characteristics directly usable for frequency management and HF channel assessment. Some sounders also store days or months of station data, which makes it possible remotely to evaluate the time history of geophysical events. The Internet link is also a convenient means for remote system maintenance and control. The paper addresses various aspects of the Internet ionosonde scenario, including data base support, WWW publishing, user interface, security, and data format. A list of Internet accessible ionosonde stations is provided with a brief description.

    Today the Internet plays a role in the lives of nearly 40% of the world's population, and it is becoming increasingly entwined in daily life. This growing presence is transforming psychological science in terms of the topics studied and the methods used. We provide an overview of the literature, considering three broad domains of research: translational (implementing traditional methods online; e.g., surveys), phenomenological (topics spawned or mediated by the Internet; e.g., cyberbullying), and novel (new ways to study existing topics; e.g., rumors). We discuss issues (e.g., sampling, ethics) that arise when doing research online and point to emerging opportunities (e.g., smartphone sensing). Psychological research on the Internet comes with new challenges, but the opportunities far outweigh the costs. By integrating the Internet, psychological research has the ability to reach large, diverse samples and collect data on actual behaviors, which will ultimately increase the impact of psychological research on society.

    2007-06-01

    The Internet goose has laid countless golden eggs, along with a growing number of rotten ones. But it's the rotten ones that now tempt commercial, governmental, and consumer interests to threaten the Internet's uniquely creative power. The expediently selected, almost accidentally generative properties of the Internet - its technical openness, ease of access and mastery, and adaptability - have combined, especially when coupled with those of the PC, to produce an unsurpassed environment for innovative experiment. Those same properties, however, also make the Internet hospitable to various forms of wickedness: hacking, porn, spam, fraud, theft, predation, and attacks on the network itself. As these undesirable phenomena proliferate, business, government, and many users find common cause for locking down Internet and PC architecture in the interests of security and order. PC and Internet security vulnerabilities are a legitimate menace. However, the most likely reactions - if they are not forestalled - will be at least as unfortunate as the security problems themselves. Consider the growing profusion of "tethered appliances" - devices whose functions cannot readily be altered by their owners (think TiVo). Such appliances take Internet innovations and wrap them up in a neat, easy-to-use package, which is good - but only if the Internet and PC can remain sufficiently in the center of the digital ecosystem to produce the next round of innovations and to generate competition. People buy these devices for their convenience or functionality and may appreciate the fact that they are safer to use (they limit the damage users can do through ignorance or carelessness). But the risk is that users, by migrating to such appliances, will unwittingly trade away the future benefits of generativity - a loss that will go unappreciated even as innovation tapers off.

  19. Strategy and the Internet.

    Science.gov (United States)

    Porter, M E

    2001-03-01

    Many of the pioneers of Internet business, both dot-coms and established companies, have competed in ways that violate nearly every precept of good strategy. Rather than focus on profits, they have chased customers indiscriminately through discounting, channel incentives, and advertising. Rather than concentrate on delivering value that earns an attractive price from customers, they have pursued indirect revenues such as advertising and click-through fees. Rather than make trade-offs, they have rushed to offer every conceivable product or service. It did not have to be this way--and it does not have to be in the future. When it comes to reinforcing a distinctive strategy, Michael Porter argues, the Internet provides a better technological platform than previous generations of IT. Gaining competitive advantage does not require a radically new approach to business; it requires building on the proven principles of effective strategy. Porter argues that, contrary to recent thought, the Internet is not disruptive to most existing industries and established companies. It rarely nullifies important sources of competitive advantage in an industry; it often makes them even more valuable. And as all companies embrace Internet technology, the Internet itself will be neutralized as a source of advantage. Robust competitive advantages will arise instead from traditional strengths such as unique products, proprietary content, and distinctive physical activities. Internet technology may be able to fortify those advantages, but it is unlikely to supplant them. Porter debunks such Internet myths as first-mover advantage, the power of virtual companies, and the multiplying rewards of network effects. He disentangles the distorted signals from the marketplace, explains why the Internet complements rather than cannibalizes existing ways of doing business, and outlines strategic imperatives for dot-coms and traditional companies.

IPTV is a service for the delivery of broadcast TV, movies on demand and other interactive multimedia services over a secure, end-to-end operator managed broadband IP data network with desired QoS to the public with a broadband Internet connection. IPTV system may also include Internet services such as Web access and VoIP where it may be called Triple Play and is typically supplied by a broadband operator using the same infrastructure. IPTV is not the Internet Video that simply allows users to watch videos, like movie previews and web-cams, over the Internet in a best effort fashion. IPTV technology offers revenue-generating opportunities for the telecom and cable service providers. For traditional telephone service providers, Triple Play is delivered using a combination of optical fiber and Digital Subscriber Line (DSL technologies to its residential base. IPTV is a system where a digital television service is delivered by using Internet Protocol over a network infrastructure, which may include delivery by a broadband connection. A general definition of IPTV is television content that, instead of being delivered through traditional broadcast and cable formats, is received by the viewer through the technologies used for computer networks. In this paper I am trying to discuss this topic as my knowledge, including what is IPTV, how it works, its advantages and its applications

    Communications systems have always been a critical element in aviation. Until recently, nearly all communications between the ground and aircraft have been based on analog voice technology. But the future of global aviation requires a more sophisticated "information infrastructure" which not only provides more and better communications, but integrates the key information functions (communications, navigation, and surveillance) into a modern, network-based infrastructure. Satellite communications will play an increasing role in providing information infrastructure solutions for aviation. Developing and adapting satellite communications technologies for aviation use is now receiving increased attention as the urgency to develop information infrastructure solutions grows. The NASA Glenn Research Center is actively involved in research and development activities for aeronautical satellite communications, with a key emphasis on air traffic management communications needs. This paper describes the recent results and status of NASA Glenn's research program.

    The Magnus effect is well-known for its influence on the flight path of a spinning ball. Besides ball games, the method of producing a lift force by spinning a body of revolution in cross-flow was not used in any kind of commercial application until the year 1924, when Anton Flettner invented and built the first rotor ship Buckau. This sailboat extracted its propulsive force from the airflow around two large rotating cylinders. It attracted attention wherever it was presented to the public and inspired scientists and engineers to use a rotating cylinder as a lifting device for aircraft. This article reviews the application of Magnus effect devices and concepts in aeronautics that have been investigated by various researchers and concludes with discussions on future challenges in their application.

    The NASA Lewis Research Center has installed an Electronic Pressure Profile Display system. This system provides for the real-time display of pressure readings on high resolution graphics monitors. The Electronic Pressure Profile Display system will replace manometer banks currently used in aeronautic test facilities. The Electronic Pressure Profile Display system consists of an industrial type Digital Pressure Transmitter (DPI) unit which interfaces with a host computer. The host computer collects the pressure data from the DPI unit, converts it into engineering units, and displays the readings on a high resolution graphics monitor in bar graph format. Software was developed to accomplish the above tasks and also draw facility diagrams as background information on the displays. Data transfer between host computer and DPT unit is done with serial communications. Up to 64 channels are displayed with one second update time. This paper describes the system configuration, its features, and its advantages over existing systems.

  9. Health monitoring of aeronautical structures based on vibrations measurements

    Bovio, Igor; Lecce, Leonardo

    2006-03-01

    Purpose of the paper is to present an innovative application inside the Non Destructive Testing field based on vibrations measurements, developed by the authors during the last three years, and already tested for analysing damage of many structural elements. The proposed new method is based on the acquisition and comparison of Frequency Response Functions (FRFs) of the monitored structure before and after an occurred damage. Structural damage modify the dynamical behaviour of the structure such as mass, stiffened and damping, and consequently the FRFs of the damaged structure in comparison with the FRFs of the sound structure, making possible to identify, to localize and quantify a structural damage. The activities, presented in the paper, mostly focused on a new FRFs processing technique based on the determining of a representative "Damage Index" for identifying and analysing damage both on real scale aeronautical structural components, like large-scale fuselage reinforced panels, and on aeronautical composite panels. Besides it has been carried out a dedicated neural network algorithm aiming at obtaining a "recognition-based learning"; this kind of learning methodology permits to train the neural network in order to let it recognises only "positive" examples discarding as a consequence the "negative" ones. Within the structural NDT a "positive" example means "healthy" state of the analysed structural component and, obviously, a "negative" one means a "damaged" or perturbed state. From an architectural point of view piezoceramic patches have been tested as actuators and sensors. Besides it has been used a laser-scanning vibrometer system to validate the behaviour of the piezoceramic patches.

    Full Text Available The effect of stressors, including heavy metal ions such as Cu2+, promotes activation of free radical processes in the cells of microorganisms, which causes changes in their physiological and biochemical properties and the structure of bacterial membranes. The aim of this work was to assess the influence of copper (II sulphate on intensity of lipid peroxidation (LPO of Chlorobium limicola IMV K-8 by measuring the content of primary (conjugated dienes and lipid hydroperoxides and secondary lipid peroxidation products (TBA-reactive products. Microorganisms were cultivated at a temperature of 28 °C in GSB cultivation medium with exposure to light of wavelength 700–800 nm and intensity 40 lux. A suspension of C. limicola ІМV К-8 cells in the phase of exponential growth was treated for one hour with metal salt solution in concentrations 0.05–0.50 mM for investigation of the influence of copper (II sulphate on its physiological and biochemical properties. The control samples did not contain any copper (II sulphate. Biomass was determined by turbidity of diluted cell suspension by application of photoelectric colorimeter KFK-3. A mixture of n-heptane and isopropyl alcohol was added into cell-free extract for conjugated dienes determination. The samples were incubated at room temperature and centrifuged. Water was added into the supernatant and the samples were stirred. Ethanol was added to the heptanes phase and adsorption was measured at 233 nm. The content of lipid hydroperoxides was determined by a method based on protein precipitation by trichloroacetic acid followed by addition of ammonium thiocyanate. The concentration of TBA-reactive products in the cell-free extracts was determined by color reaction with malondialdehyde and thiobarbituric acid exposed to high temperature and acidity of the medium, which causes formation of trimetinic adduct with maximal absorption at 532 nm. It was shown that when CuSO4 was added to the incubation

    Full Text Available Internet is transforming lives of many people in the world. Nowadays Internet has become one of the most common media to extract information of interest to researchers. The Internet is composed of a large number of smaller interconnected networks called Intranets. These Intranets connect thousands computers enabling them to share information with each other and to share various resources such as powerful super computers, software and databases of information. It has made it possible for people all over the world to effectively and inexpensively communicate with each other. The Internet has become world′s biggest library where retrieval of scientific resources is only a mouse click away. The geometric growth in Internet usage is mainly due to the great success of "World Wide Web". Various useful databases on diabetes are already on ′the Net′ and many more being added regularly. The present article is an attempt to provide a review of several sites that may be of great significance to the diabetes researchers before execution for new assignment/project.

  16. Internet Congestion Control System

    Directory of Open Access Journals (Sweden)

    Pranoto Rusmin

    2010-10-01

    Full Text Available Internet congestion occurs when resource demands exceeds the network capacity. But, it is not the only reason. Congestion can happen on some users because some others user has higher sending rate. Then some users with lower sending rate will experience congestion. This partial congestion is caused by inexactly feedback. At this moment congestion are solved by the involvement of two controlling mechanisms. These mechanisms are flow/congestion control in the TCP source and Active Queue Management (AQM in the router. AQM will provide feedback to the source a kind of indication for the occurrence of the congestion in the router, whereas the source will adapt the sending rate appropriate with the feedback. These mechanisms are not enough to solve internet congestion problem completely. Therefore, this paper will explain internet congestion causes, weakness, and congestion control technique that researchers have been developed. To describe congestion system mechanisms and responses, the system will be simulated by Matlab.

    Grothkopf, U.

    Librarianship is currently undergoing major changes. New information sources, accessible via the "network of networks", the Internet, offer opportunities which were previously unknown, but which require continuous ongoing learning. The Internet seems to be organized badly or not at all. The poor appearance might lead to an underestimation of its value. In the following, an introduction to the main functions will be given in order to facilitate understanding and use of the Internet. E-Mail, FTP (File Transfer Protocol) and Telnet will be covered, as well as Mailing lists, Newsgroups and the tools Archie, Gopher, Veronica, WAIS (Wide Area Information Server) and the World Wide Web (WWW). Examples will be given to show possible applications for library services.

    1991-09-01

    This study investigated the major schools of thought on various aspects of quality management and quality improvement. Areas covered included definitions of waste and quality, views on the cost of quality, tools and techniques used for quality improvement, and management philosophies and frameworks for continuous improvement. In addition, this study analyzed the structure and training content of the current Total Quality Management program at Aeronautical Systems Division (ASD). Pre- and post-test surveys on employee attitudes toward organizational effectiveness were analyzed from the Advanced Cruise Missile System Program Office (SPO), the F-15 SPO, and the ASD Deputy Chief of Staff for Human Resources (ASD/DP). Data was supplemented with semi-structured, personal interviews with ASD personnel involved in TQM. Survey analysis showed that the ACM SPO significantly improved, ASD/DP significantly digressed, and the F-15 SPO remained basically consistent. This led to the conclusion that ASD allows too much flexibility in the implementation of TQM in the three-letter organizations.

    2015-01-01

    In support of the mission-specific challenges of aeronautics and space exploration, NASA Ames produces a wealth of research and technology advancements with significant relevance to larger issues of planetary sustainability. NASA research on NexGen airspace solutions and its development of autonomous and intelligent technologies will revolutionize both the nation's air transporation systems and have applicability to the low altitude flight economy and to both air and ground transporation, more generally. NASA's understanding of the Earth as a complex of integrated systems contributes to humanity's perception of the sustainability of our home planet. Research at NASA Ames on closed environment life support systems produces directly applicable lessons on energy, water, and resource management in ground-based infrastructure. Moreover, every NASA campus is a 'city'; including an urbanscape and a workplace including scientists, human relations specialists, plumbers, engineers, facility managers, construction trades, transportation managers, software developers, leaders, financial planners, technologists, electricians, students, accountants, and even lawyers. NASA is applying the lessons of our mission-related activities to our urbanscapes and infrastructure, and also anticipates a leadership role in developing future environments for living and working in space.

  11. Crack path in aeronautical titanium alloy under ultrasonic torsion loading

    Directory of Open Access Journals (Sweden)

    A. Nikitin

    2016-01-01

    Full Text Available This paper discusses features of fatigue crack initiation and growth in aeronautical VT3-1 titanium alloy under pure torsion loading in gigacycle regime. Two materials: extruded and forged VT3-1 titanium alloys were studied. Torsion fatigue tests were performed up to fatigue life of 109 cycles. The results of the torsion tests were compared with previously obtained results under fully reversed axial loading on the same alloys. It has been shown that independently on production process as surface as well subsurface crack initiation may appear under ultrasonic torsion loading despite the maximum stress amplitude located at the specimen surface. In the case of surface crack initiation, a scenario of crack initiation and growth is similar to HCF regime except an additional possibility for internal crack branching. In the case of subsurface crack, the initiation site is located below the specimen surface (about 200 μm and is not clearly related to any material flaw. Internal crack initiation is produced by shear stress in maximum shear plane and early crack growth is in Mode II. Crack branching is limited in the case of internal crack initiation compared to surface one. A typical ‘fish-eye’ crack can be observed at the torsion fracture surface, but mechanism of crack initiation seems not to be the same than under axial fatigue loading.

    Full text: Zirconium-based ceramic materials are widely employed as Thermal Barrier Coatings (TBC), due to its excellent wear and corrosion resistance at high temperatures. The application of TBC includes aeronautical and industrials turbine blades. The working conditions include oxidizing environments and temperatures above 1000°C. The zirconium-based ceramics are developed in such a way that the microstructural control is possible through the control of chemical composition, fabrication route and, thermal treatment. The present paper proposes a laser route to deposit the TBC coating, where the microstructural control is a function of power density and interaction time between the laser beam and the material. The main objective of this work is to study the influence of the CO2 laser beam (Synrad Evolution 125) parameters: power density and interaction time, on the deposition process of yttria-stabilized zirconia (YSZ) powders on NiCrAlY/AISI 316L substrates. The resulting coating surface and interface were characterized by scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction. The results indicate that is possible to match laser parameters of scanning speed and intensity to produce homogenous coatings. The X-Ray analyses show that the obtained ceramic coating has reduced number of phases, with prevalence of tetragonal phase.(author)

  16. Internet, Cybersex and Infidelity

    Directory of Open Access Journals (Sweden)

    Verda Tuzer

    2011-03-01

    Full Text Available Increasing use of internet has numerous reflections on relationships. Within the range of chatroom friendship and flirting to shared sexuality, cybersex addiction and criminal behaviours are among the most intriguing. Searching for sexual satisfaction on internet may have a number of functions such as decreasing anxiety and distress; expressing emotions such as loneliness, depression, anger and disappointment; or providing support to not being able to judge the level of intimacy in a realtionship. The incredible ease with which one obtains sexual content on the internet, at home, at the work place or even through mobile phones is one of the most important reason for its widespread prevalence. Another important allure of the cybersex is its anonimity, the relative ease to disguise normally disturbing characteristics and its being mostly ignored by others. It is also low-cost. On the other hand it causes increased social isolation, damages trust in relationships, and causes the individual to seek for help due to dramatic consequences following a period of virtual mirroring, when the feeling of finding a soulmate causes mutual adoration and idealization. This review examines the definition of infidelity in the context of internet use, its characteristics, types and various aspects; its negative consequences on relationships; its effects on couples and families; and treatment alternatives. The problems caused by increasing compulsivity of cybersex are also highlighted.

    Full Text Available Turkey passed an internet censorship law in 2007 with the declared objective of protecting families and minors (Akdeniz, 2010. It established a unit within the regulator BTK (Information and Communication Technologies Authority responsible for imposing bans and blocks on websites based on nine catalogue crimes defined by other national laws (Akgül 2008, 2009a, 2009b. As of May 2015, 80,000 websites were banned based on civil code related complaints and intellectual property rights violations, reports the independent website Engelliweb. Blocking decisions rendered by penal courts are enforced even when they are based on grounds other that the nine catalogue crimes - such as terrorism, organised crime and crime against the state. Passed in parliament while ignoring the pleas of NGOs and of the internet sector, the Internet Law No. 5651 has since been used to temporarily ban popular platforms such as Blogger, Last.fm, Vimeo, Wordpress and YouTube. At the same time, some blocking decisions by the courts (e.g., Google and Facebook were not enforced by the authorities. Since its introduction, the European Court of Human Rights has ruled that Law No. 5651 (Council of Europe, 2011 is against the European Convention on Human Rights (ECHR, 2013.

    Full Text Available This paper looks at the tandem technologies of cars and the Internet, and the new ways that they are assembling the social with the mobile Internet. My argument is two-fold: firstly, the advent of mobile Internet in cars brings together new, widely divergent trajectories of Internet; secondly, such developments have social implications that vary widely depending on whether or not we recognize the broader technological systems and infrastructures, media practices, flows, and mobilities in which vehicular mobile Internets are being created.

Families which have children between the ages of 10-18 and an internet connection at home were included in the research. Residing in the central town of Konya with 15 families were interviewed. Each interview lasted approximately 20 minutes. Descriptive analysis was made in the analyzing of data come by at the end of research. In conclusion, the biggest reason for families to connect to the internet is supporting their children to study and preventing their children go to internet cafes. Families said that their children are using the internet to play the game. About half of families agreed verbally with their children about using internet, but any family does not agree in writing. Twelve families do not use any filter program when they connected to internet. Families understand that their children are addicted to the internet, spending more time on the internet, having communication problems with their families, being disruption of daily life patterns, attending classes and failing lessons. If families’ child is addicted to internet many of them warn verbally and say ban the internet, only four of families said get help from experts. Results of research findings compared with literature and discussed.

    2014-07-01

    In our technology-savvy population, mental health professionals are seeing an increasing trend of excessive Internet use or Internet addiction. Researchers in China, Taiwan and Korea have done extensive research in the field of Internet addiction. Screening instruments are available to identify the presence of Internet addiction and its extent. Internet addiction is frequently associated with mental illnesses such as anxiety, depression, conduct disorder and attention deficit hyperactivity disorder (ADHD). Treatment modalities include individual and group therapies, cognitive behavioural therapy (CBT), family therapy and psychotropic medications. A significant proportion of Singapore adolescents engaging in excessive Internet use are also diagnosed to have concomitant Internet addiction. Despite the presence of a variety of treatment options, future research in this area is needed to address its growing trend and to minimise its negative psychological and social impact on the individuals and their families.

    Full Text Available Some addictions cannot be connected with substance abuse (pathological gambling, video games playing, binge eating, compulsive physical activity, emotional relationship addiction, TV addiction. Since 1995, Internet addiction has been accepted as a clinical entity with profound negative effect on social, familial, educational and economical personal functioning. The diagnosis of Internet addiction could be established if the person spends more than 38 hours per week on the Internet exempting online professional needs. Basic symptoms are the increased number of hours spent in front of the computer along with the Internet use, development of abstinent syndrome if the Internet access is prohibited, sleep inversion, neglect of basic social requirements and personal hygiene, many somatic symptoms developed due to prolonged sitting or monitor watching, dissocial behavior. In this paper, data about the Internet addiction are presented and a case report of an adolescent with developed Internet addiction.

    Full Text Available With the introduction of new technologies, computer and internet use have become an unavoidable necessity in our daily lives. Internet was originally designed to facilitate communication and research. However the dramatic increase in use of internet in recent years has led to its pathologic use. Turkey, as a developing country with an increasing rate of internet access and computer use is at high risk for this disorder. In our country, this disorder is especially seen in young people who are more skilled in internet and computer use. And because their excessive internet use has led to negative consequences in their academic, social and family lives, patients and their families began search of treatment for this disorder. So clinicians must be aware of this newly emerging disorder and they should be able to apply the appropriate therapeutic interventions. This paper aims to summarize the pharmacological and cognitive-behavioral treatment of internet addiction.

    2016-02-01

    The Internet has revolutionized the way knowledge is currently produced, stored and disseminated. A few finger clicks on a keyboard can save time and many hours of search in libraries or shopping in stores. Online trademarks with an (e-) prefix such as e-library, e-business, e-health etc., are increasingly part of our daily professional vocabularies. However, the Internet has also produced multiple negative side effects, ranging from an unhealthy dependency to a dehumanization of human relationships. Fraudulent, unethical and scam practices are also flourishing through for example misleading online advertising methods. Some social and professional networks gather users' profiles for selling and advertising purposes, sometimes by making it technically difficult to unsubscribe. Here, I discuss some of these unethical aspects and propose some potential solutions to reduce them.

La Internet de hoy es tan distinta de lo que fue que poca gente recuerda cómo se gestó y cual era su 'espíritu' en los comienzos. La Red de redes fue el resultado de un proceso, no previsto, que empezó como red militar, siguió como red universitaria, luego alcanzó nivel intercontinental y finalmente se globalizó tanto como el mundo al que ella misma contribuyó a unificar.

Those who designed what we now call the internet during the first decade of the effort (1969-1979, who in essence served simultaneously as its policy-makers, developed techniques for coping with instability of value for network designers today and for those involved with any kind of large-scale sociotechnical infrastructure. Analysis of the technical document series that was medium for and record of that design process reveals coping techniques that began with defining the problem and went on to include conceptual labour, social practices, and technical approaches.

    We turn on the lights in our house from a desk in an office miles away. Our refrigerator alerts us to buy milk on the way home. A package of cookies on the supermarket shelf suggests that we buy it, based on past purchases. The cookies themselves are on the shelf because of a "smart" supply chain. When we get home, the thermostat has already adjusted the temperature so that it's toasty or bracing, whichever we prefer. This is the Internet of Things -- a networked world of connected devices, objects, and people. In this book, Samuel Greengard offers a guided tour through this emerging world and how it will change the way we live and work. Greengard explains that the Internet of Things (IoT) is still in its early stages.

    Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in women and is characterised by polycystic ovaries, hyperandrogenism and chronic anovulation. Although the clinical and biochemical signs of PCOS are typically heterogeneous, abnormal folliculogenesis is considered a common characteristic of PCOS. Our aim is to identify the altered miRNA and mRNA expression profiles in the cumulus cells of PCOS patients to investigate their molecular function in the aetiology and pathophysiology of PCOS. In this study, the miRNA expression profiles of the cumulus cell samples isolated from five PCOS and five control patients were determined by an miRNA microarray. At the same time, the altered mRNA profiles of the same cumulus cell samples were also identified by a cDNA microarray. From the microarray data, 17 miRNAs and 1263 mRNAs showed significantly different expression in the PCOS cumulus cells. The differentially expressed miRNA-509-3p and its potential target gene (MAP3K8) were identified from the miRNA and mRNA microarrays respectively. The expression of miRNA-509-3p was up-regulated and MAP3K8 was down-regulated in the PCOS cumulus cells. The direct interaction between miRNA-509-3p and MAP3K8 was confirmed by a luciferase activity assay in KGN cells. In addition, miRNA-509-3p mimics or inhibitor transfection tests in KGN cells further confirmed that miRNA-509-3p improved oestradiol (E2) secretion by inhibiting the expression of MAP3K8 These results help to characterise the pathogenesis of anovulation in PCOS, especially the regulation of E2 production.

    Adolescent Internet gambling is associated with concomitant addictive behaviors. This study aimed to assess the prevalence of Internet gambling practices, its impact upon psychosocial development and to evaluate the association between gambling practices and Internet addictive behavior among Cypriot adolescents. A cross-sectional study was conducted in a convenience sample (n = 805) of adolescents attending selected public schools (9th and 10th grades) in Cyprus. Anonymous self-completed questionnaires were used including the Internet Addiction Test and the Strengths and Difficulties Questionnaire. Among the study population (n = 805), approximately one third (n = 28; 34.9%) reported Internet gambling. Internet gamblers were twice as likely to utilize Internet café portals (adjusted odds ratio for gender and age, AOR: 2.13; 95% confidence interval, 95% CI: 1.56-2.91) for interactive game-playing (AOR: 6.84; 95% CI: 4.23-11.07), chat-rooms (AOR: 2.57; 95% CI: 1.31-4.85), and retrieval of sexual information (AOR: 1.99; 95% CI: 1.42-2.81). Among Internet gamblers 26.0% (n = 73) reported borderline addictive Internet use and 4.3% (n = 12) addictive behavior. Internet gamblers more often had comprehensive psychosocial and emotional maladjustment (AOR: 4.00; 95% CI: 1.97-8.13), including Abnormal Conduct Problems (AOR: 3.26; 95% CI: 2.00-5.32), Emotional Symptoms (AOR: 1.78; 95% CI: 1.02-3.11), and Peer Problems (AOR: 2.44; 95% CI: 1.08-5.48) scores. The multivariate regression analyses indicated that the single independent predictor associated with Internet addictive behavior was Internet gambling (AOR: 5.66; 95% CI: 1.45-22.15). Internet gambling is associated with addictive Internet use, as well as emotional maladjustment and behavioral problems, among Cypriot adolescents. Longitudinal studies are needed to elucidate whether Internet gambling constitutes a risk factor for the development of Internet addictive behavior among adolescents.

    Andersen, Thomas Barnebeck; Bentzen, Jeanet Sinding; Dalgaard, Carl-Johan Lars

    2011-01-01

    We test the hypothesis that the Internet is a useful technology for controlling corruption. In order to do so, we develop a novel identification strategy for Internet diffusion. Power disruptions damage digital equipment, which increases the user cost of IT capital, and thus lowers the speed...... and a large cross section of countries. Empirically, lightning density is a strong instrument for Internet diffusion and our IV estimates suggest that the emergence of the Internet has served to reduce the extent of corruption across U.S. states and across the world....

    Library resources are prevalent on the Internet. Library catalogs, electronic books, electronic periodicals, periodical indexes, reference sources, and U.S. Government documents are available by telnet, Gopher, World Wide Web, and FTP. Comparatively few copyrighted library resources are available freely on the Internet. Internet implementations of library resources can add useful features, such as full-text searching. There are discussion lists, Gophers, and World Wide Web pages to help users keep up with new resources and changes to existing ones. The future will bring more library resources, more types of library resources, and more integrated implementations of such resources to the Internet.

  16. Measuring QoS in an Aeronautical Opportunistic Network Architecture with Limited Access to a Satellite Communications Backhaul

    Directory of Open Access Journals (Sweden)

    Rubén Martínez-Vidal

    2016-01-01

    Full Text Available We measure quality of service (QoS in a wireless network architecture of transoceanic aircraft. A distinguishing characteristic of the network scheme we analyze is that it mixes the concept of Delay Tolerant Networking (DTN through the exploitation of opportunistic contacts, together with direct satellite access in a limited number of the nodes. We provide a graph sparsification technique for deriving a network model that satisfies the key properties of a real aeronautical opportunistic network while enabling scalable simulation. This reduced model allows us to analyze the impact regarding QoS of introducing Internet-like traffic in the form of outgoing data from passengers. Promoting QoS in DTNs is usually really challenging due to their long delays and scarce resources. The availability of satellite communication links offers a chance to provide an improved degree of service regarding a pure opportunistic approach, and therefore it needs to be properly measured and quantified. Our analysis focuses on several QoS indicators such as delivery time, delivery ratio, and bandwidth allocation fairness. Obtained results show significant improvements in all metric indicators regarding QoS, not usually achievable on the field of DTNs.

    Full Text Available In today’s ever-shifting media landscape, it can be a complex task to find effective ways to reach your desired audience. As traditional media such as television continue to lose audience share, one venue in particular stands out for its ability to attract highly motivated audiences and for its tremendous growth potential the 3D Internet. The concept of '3D Internet' has recently come into the spotlight in the R&D arena, catching the attention of many people, and leading to a lot of discussions. Basically, one can look into this matter from a few different perspectives: visualization and representation of information, and creation and transportation of information, among others. All of them still constitute research challenges, as no products or services are yet available or foreseen for the near future. Nevertheless, one can try to envisage the directions that can be taken towards achieving this goal. People who take part in virtual worlds stay online longer with a heightened level of interest. To take advantage of that interest, diverse businesses and organizations have claimed an early stake in this fast-growing market. They include technology leaders such as IBM, Microsoft, and Cisco, companies such as BMW, Toyota, Circuit City, Coca Cola, and Calvin Klein, and scores of universities, including Harvard, Stanford and Penn State.

  10. Network architecture as internet governance

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available The architecture of a networked system is its underlying technical and logical structure, including transmission equipment, communication protocols, infrastructure, and connectivity between its components or nodes. This article introduces the idea of network architecture as internet governance, and more specifically, it outlines the dialectic between centralised and distributed architectures, institutions and practices, and how they mutually affect each other. The article argues that network architecture is internet governance in the sense that, by changing the design of the networks subtending internet-based services and the global internet itself, its politics are affected – the balance of rights between users and providers, the capacity of online communities to engage in open and direct interaction, the fair competition between actors of the internet market.

This report explains the relationship between the practice of Internet censorship imposed by the Chinese government and the freedom of its citizens (in the internet surfing experience as the realization of human rights in the freedom of expression and opinion (seek, receive-use, and communicate information which is traced through the relevant literature study. China is a unique case since the internet censorship regulation contributes to its status as the country with the least internet freedom yet at the same time it is credited as having the most internet users globally. In addition, China known as the communist country that began opening up to globalization and information of technology, but the government’s control over it is still so tight and binding, not only in the press, or the traditional media, but also in new media with the internet censorship. The control over this information may have a clear objective to maintain a climate of information in the community, but on the other hand, such control is tantamount to restricting the right of citizens to make, use, and distribute information, and more fatal as a violation of human rights.

    In an era when social media sites like YouTube, Facebook, and Twitter dominate the popular press, many surgeons overlook the foundational tactics and strategies necessary for long-term practice development and lead generation on the Internet. This article analyzes common errors made by surgeons during the development and implementation of Web site projects, focusing on the areas of strategy development; domain name identification; site plan creation; design considerations; content development; vendor selection; and launch, promotion, and staff training. The article emphasizes that, because the Web site remains the foundation of a surgeon's branding message, minimizing errors during development and construction is critical, particularly in highly competitive or saturated markets, for today's facial plastic surgery practice.

    The aim of the study was to compare first and second generation Digital Natives' attitudes toward and use of the Internet. The sample of first generation Digital Natives consisted of 558 students who we surveyed in 2002 and who were born after 1980. The sample of second generation Digital Natives consisted of a sample of 458 students who we surveyed in 2012 and were born after 1993. They completed a questionnaire in the first semester of their first academic year, which consisted of a measure of Internet experience, an Internet anxiety scale, and an Internet identification scale. Second generation Digital Natives had more positive attitudes toward the Internet than first generation Digital Natives. They had higher scores on the Internet identification scale and lower scores on the Internet anxiety scale compared with first generation Digital Natives. Furthermore, we found that second generation Digital Natives used the Internet more than first generation Digital Natives. E-mail was the most popular activity for both generations, although second generation Digital Natives used it significantly more than first generation Digital Natives. Social networking sites emerged as very popular for second generation Digital Natives. Both generations reported low use of Web 2.0 technologies.

    Internet communications today play a major role in data transport within the local as well as the wide area. On one hand, since emerging networked applications require a variety of different communication services, the number of service classes offered by service providers has to be targeted at this demand. On the other hand, assuming that a set of different traffic classes are offered by service providers, the 'right' incentives have to be provided, ensuring that applications or their users select the most appropriate traffic class. Even though users are considered to be selective, they intend to chose that class which offers the best available Quality-of-Service (QoS), as long as the price to be paid does not exceed their willingness-to-pay. Therefore, charging for differentiated Internet services is important in a commercialized Internet. The current Internet does not cater for charging at all, since the technology required, the pricing models going beyond a flat-fee approach, and the appropriate efficiency in technical as well as economic terms are still missing on a global basis. This paper outlines the major problems for charging Internet services and describes briefly an important new solution for a pricing approach, which solves the Internet pricing feasibility problem. Based on these preconditions an Internet Charging System (ICS) is introduced, focusing mainly on its leading characteristics and its generic approach to instantiate for a given scenario.

  17. A Glimpse of Scientific Research on Fundamental Problems of Military and Civil Aeronautics

    Science.gov (United States)

    1939-01-01

    Among the outstanding accomplishments of the last century is man's conquest of the air. That conquest began in 1903 when the Wright brothers made the first successful flight of an airplane at Kitty Hawk, N. C. Five years later the United States Government purchased its first airplane for the use of the Army, and began the training of officers for military flying. During the years immediately preceding the outbreak of the World War the Government and a meager aircraft industry had made important progress, but the Government, practically the only customer, had purchased less than 100 airplanes. In the meantime, leading European nations, sensing acutely the potentialities of aircraft in warfare, had made greater progress and had begun laying the foundations for the new science of aeronautics. The World War gave a remarkable impetus to the development of aeronautics and emphasized the need for organized research on the fundamental problems of flight. By act of Congress approved March 3, 1915, the National Advisory Committee for Aeronautics was created and charged with the duty of supervising, directing, and conducting fundamental scientific research and experiment in aeronautics. With the farsighted support of the Congress the Committee has led the world in the development of unique aeronautical research facilities in its laboratories at Langley Field, Va. The research programs include problems initiated by the Committee and its subcommittees and also investigations requested by the Army, the Navy, and the Civil Aeronautics Authority. The results of researches conducted under one control, serve without duplication of effort, the needs of all branches of aviation, civil and military, and exert a profound influence on the progress of aeronautics by improving the performance, efficiency, and safety of aircraft. A brief description of the results of some of the committee's researches and of the equipment employed will be found in the following pages.

    In the 2000s, online games became popular, while studies of Internet gaming addiction emerged, outlining the negative consequences of excessive gaming, its prevalence, and associated risk factors. The establishment of specialized treatment centers in South-East Asia, the US, and Europe reflects the growing need for professional help. It is argued that only by understanding the appeal of Internet gaming, its context, and neurobiologic correlates can the phenomenon of Internet gaming addiction be understood comprehensively. The aim of this review is to provide an insight into current perspectives on Internet gaming addiction using a holistic approach, taking into consideration the mass appeal of online games, the context of Internet gaming addiction, and associated neuroimaging findings, as well as the current diagnostic framework adopted by the American Psychiatric Association. The cited research indicates that the individual’s context is a significant factor that marks the dividing line between excessive gaming and gaming addiction, and the game context can gain particular importance for players, depending on their life situation and gaming preferences. Moreover, the cultural context is significant because it embeds the gamer in a community with shared beliefs and practices, endowing their gaming with particular meaning. The cited neuroimaging studies indicate that Internet gaming addiction shares similarities with other addictions, including substance dependence, at the molecular, neurocircuitry, and behavioral levels. The findings provide support for the current perspective of understanding Internet gaming addiction from a disease framework. The benefits of an Internet gaming addiction diagnosis include reliability across research, destigmatization of individuals, development of efficacious treatments, and the creation of an incentive for public health care and insurance providers.

    Each database in this review has features that will appeal to some users. Each provides a credible interface to information available within the Medline database. The major differences are pricing and interface design. In this context, features that cost more and might seem trivial to the occasional searcher may actually save time and money when used by the professional. Internet Grateful Med is free, but Ms. Coady and I agree the availability of only three ANDable search fields is a major functional limitation. PubMed is also free but much more powerful. The command line interface that permits very sophisticated searches requires a commitment that casual users will find intimidating. Ms. Coady did not believe the feedback currently provided during a search was sufficient for sustained professional use. Paper Chase and Knowledge Finder are mature, modestly priced Medline search services. Paper Chase provides a menu-driven interface that is very easy to use, yet permits the user to search virtually all of Medline's data fields. Knowledge Finder emphasizes the use of natural language queries but fully supports more traditional search strategies. The impact of the tradeoff between fuzzy and Boolean strategies offered by Knowledge Finder is unclear and beyond the scope of this review. Additional software must be downloaded to use all of Knowledge Finders' features. Other providers required no software beyond the basic Internet browser, and this requirement prevented Ms. Coady from evaluating Knowledge Finder. Ovid and Silver Platter offer well-designed interfaces that simplify the construction of complex queries. These are clearly services designed for professional users. While pricing eliminates these for casual use, it should be emphasized that Medline citation access is only a portion of the service provided by these high-end vendors. Finally, we should comment that each of the vendors and government-sponsored services provided prompt and useful feedback to e

    The forecasting of reliability and life of aeronautical hardware requires recognition of many and various destructive processes that deteriorate the health/maintenance status thereof. The aging of technical components of aircraft as an armament system proves of outstanding significance to reliability and safety of the whole system. The aging process is usually induced by many and various factors, just to mention mechanical, biological, climatic, or chemical ones. The aging is an irreversible process and considerably affects (i.e. reduces) reliability and lifetime of aeronautical equipment. Application of the characteristic function of the aging process is suggested to predict reliability and lifetime of aeronautical hardware. An increment in values of diagnostic parameters is introduced to formulate then, using the characteristic function and after some rearrangements, the partial differential equation. An analytical dependence for the characteristic function of the aging process is a solution to this equation. With the inverse transformation applied, the density function of the aging of aeronautical hardware is found. Having found the density function, one can determine the aeronautical equipment's reliability and lifetime. The in-service collected or the life tests delivered data are used to attain this goal. Coefficients in this relationship are found using the likelihood function.

The cycle comprises five stages from the initial technology trigger through to a final plateau of productivity along a with a peak of inflated expectations, a tough of disillusionment and the slope of enlightenment. The hype cycle is notable technique for plotting and identifying waves of innovation and hype in technology and digital communications. Yet, from where we stand, we can see the waves of innovation becoming increasingly shorter, the troughs less deep and the peaks of expectations higher. The read-write revolution, that is arguably known as Web 2.0, has transformed our experience of using the Internet from a source of information to a means of communication and participation. It has introduced mirror worlds, the cloud, wikitecture, social shaping, connected places, folksonomies and many other terms that I am sure many of us have used in recent grant applications and papers. This is the here and now, all of these technologies are past the technology trigger point and rising up the peak of inflated expectations with a few already heading towards the trough before becoming mainstream and approaching mass adoption.

Current methods of coordinating the effects of change as they propagate through these networks of connections are not likely to scale. What is needed is a new paradigm for how the Internet supports such coordination. Indeed, the Internet should and could provide fundamental coordination functions that are missing today. In this paper, we describe how such a “Coordinated Internet” would work (this paper is an expanded version of [1]. The key functionality of a Coordinated Internet would be that the Internet actively watches what people do (analogous to search completion on desktops today, correlates these activities, and actively notifies people when and how their current tasks affect and are affected by the activities of other people. This would be accomplished by standard coordination functions implemented as a common Internet layer that can be used as a utility by more specialized applications. Such a Coordinated Internet would revolutionize enterprise management, for all enterprises, large and small, corporate and personal. For example, static workflows would become obsolete for all but the the most routine processes. Some solutions provide existence proofs of such a coordination substrate, such as the Redux solution in concurrent engineering, which we describe herein. However, foundational research remains to be done in the new field of Coordination Engineering in order to reach the goal of a future Internet in which coordination functions are fundamental.

    The purpose of the current study was to evaluate possible overlapping substance abuse and internet addiction in a large, uniformly sampled population, ranging in age from 13 to 18 years. Participants (N=73,238) in the current study were drawn from the 6th Korea Youth Risk Behavior Web-based Survey (KYRBWS-V) for students from 400 middle schools and 400 high schools in 16 cities within South Korea. Of adolescent internet users, 85.2% were general users (GU), 11.9% were users with potential risk for internet addiction (PR), and 3.0% were users with high risk for internet addiction (HR). There was a difference in the number of students with alcohol drinking among the GU, PR, and HR groups (20.8% vs 23.1% vs 27.4%). There was a difference in the number of students who smoked among the GS, PR, and HR groups (11.7% vs 13.5% vs 20.4%). There was a difference in the number of students with drug use among the GU, PR, and HR groups (1.7% vs 2.0% vs 6.5%). After adjusting for sex, age, stress, depressed mood, and suicidal ideation, smoking may predict a high risk for internet addiction (OR=1.203, p=0.004). In addition, drug use may predict a high risk for internet addiction (OR=2.591, pinternet addiction have vulnerability for addictive behaviors, co-morbid substance abuse should be evaluated and, if found, treated in adolescents with internet addiction.

  20. Adaptive Reactive Rich Internet Applications

    Rich Internet Applications significantly raise the user experience compared with legacy page-based Web applications because of their highly responsive user interfaces. Although this is a tremendous advance, it does not solve the problem of the one-size-fits-all approach1 of current Web applications. So although Rich Internet Applications put the user in a position to interact seamlessly with the Web application, they do not adapt to the context in which the user is currently working. In this paper we address the on-the-fly personalization of Rich Internet Applications. We introduce the concept of ARRIAs: Adaptive Reactive Rich Internet Applications and elaborate on how they are able to adapt to the current working context the user is engaged in. An architecture for the ad hoc adaptation of Rich Internet Applications is presented as well as a holistic framework and tools for the realization of our on-the-fly personalization approach. We divided both the architecture and the framework into two levels: offline/design-time and online/run-time. For design-time we explain how to use ontologies in order to annotate Rich Internet Applications and how to use these annotations for conceptual Web usage mining. Furthermore, we describe how to create client-side executable rules from the semantic data mining results. We present our declarative lightweight rule language tailored to the needs of being executed directly on the client. Because of the event-driven nature of the user interfaces of Rich Internet Applications, we designed a lightweight rule language based on the event-condition-action paradigm.2 At run-time the interactions of a user are tracked directly on the client and in real-time a user model is built up. The user model then acts as input to and is evaluated by our client-side complex event processing and rule engine.
