Expanding the Vision for Blueberry Extension
No full textCooperative Extension programs are in a state of flux as new methods of information delivery are adopted by agents, specialists, and clientele. Online methods are crucial tools as the number of Extension specialists with specialization in blueberries shrink. Therefore, increased communications to develop collaborations among Extension personnel should be a priority. The All About Blueberries (AAB) Community of Practice (CoP) launched in 2010 and was motivated by six goals: (1) to improve insect and disease identification; (2) to improve blueberry production efficiency and productivity; (3) to educate about blueberry cultivation; (4) to improve grower profit margins; (5) to hasten adoption of new innovations and technologies; and (6) to improve the safe handling of fresh produce by emphasizing the importance of food safety in the consumer section and harvesting in the grower section. The AAB portal and its 36 contributing authors represent an ideal venue to showcase nationwide blueberry consumer and producer research and educational efforts. The AAB CoP can provide a platform for enhanced and strategic coordination among blueberry Extension specialists nationwide. Better coordination can lead to positive outcomes that result in more recognition of Extension as a critical aspect of the research-to-end user continuum. Pursuing online methods meets clientele needs and strengthens Extension’s reach to all stakeholders and audiences, nationally and internationally. Support and expansion of the blueberry eXtension portal has great potential to be a leader in developing efficient and effective Extension methods to reach existing clientele and new audiences.Paper presented at NABREW Conference, Paper Session II:Blueberry Extension, on June 25, 2014, Atlantic City, N.J

The impact of Degraded distractors on (Nondegraded) target identification
No full textIn this series of experiments, based on Biederman's Recognition by Components theory, we postulate that corners (vertices) of objects are crucial in programming and execution of goal-directed action. We used a distractor interference paradigm to present line drawings of letters (M and W) with distractors (also M and W), which were either nondegraded or degraded (that is, corners or line segments missing). Degraded distractors caused less interference overall (reduced response times and errors) than Nondegraded distractors, when these were presented peripherally or at fixation (Experiments 1 and 2). When presented at fixation, however, distractors with corners missing caused greater interference than distractors with line segments missing. This pattern was not replicated with non-identical, non-mirror reversed stimuli (H and E: Experiment 3). We speculate that corners are critical in determining the extent of distractor interference. When missing from view, and given sufficient attentional resources and structural similarity, they may be reconstructed by the visuomotor system to aid performance to the target
An Investigation of Raman Lidar Aerosol Measurements and their Application to the study of the Aerosol Indirect Effect
No full textThe problem of the increasing global atmospheric temperature has motivated a large interest in studying the mechanisms that can influence the radiative balance of the planet. Aerosols are responsible for several radiative effects in the atmosphere: an increase of aerosol loading in the atmosphere increases the reflectivity of the atmosphere and has an estimated cooling effect and is called the aerosol direct effect. Another process involving aerosols is the effect that an increase in their concentration in the atmosphere has on the formation of clouds and is called the aerosol indirect effect. In the latest IPCC report, the aerosol indirect effect was estimated to be responsible for a radiative forcing ranging between -0.3 W/m2 to -1.8 W/m2, which can be as large as, but opposite in sign to, the radiative forcing due to greenhouse gases. The main goal of this dissertation is to study the Raman lidar measurements of quantities relevant for the investigation of the aerosol indirect effect and ultimately to apply these measurements to a quantification of the aerosol indirect effect. In particular we explore measurements of the aerosol extinction from both the NASA Goddard Space Flight Center Scanning Raman Lidar (SRL) and the US Department of Energy (DOE) ARM Climate Research Facility Raman Lidar (CARL). An algorithm based on the chi-squared technique to calculate the aerosol extinction, which was introduced first by Whiteman (1999), is here validated using both simulated and experimental data. It has been found as part of this validation that the aerosol extinction uncertainty retrieved with this technique is on average smaller that the uncertainty calculated with the technique traditionally used. This algorithm was then used to assess the performance of the CARL aerosol extinction retrieval for low altitudes. Additionally, since CARL has been upgraded with a channel for measuring Raman liquid water scattering, measurements of cloud liquid water content, droplet radius and droplet number density using this new capability have been studied. Some discrepancies are found between the CARL and AERI measurements of liquid water path and droplet effective radius and they need to be studied in more detail when a larger dataset is available. To study the correlation between aerosol presence and cloud microphysics the calculations of IE, introduced by Feingold as a parameterization of the aerosol indirect effect, has been performed here for the first time using exclusively Raman lidar data. The work shown here is an indication that the combined measurements of aerosol extinction, cloud liquid water content, droplet radius and droplet number density with a Raman lidar represents an interesting new technique for the study of the aerosol indirect effect
On the high accuracy to test dragging of inertial frames with the LARES 2 space experiment
No full textIn this paper we treat some aspects of the LARES 2 space experiment to test the general relativistic phenomenon of dragging of inertial frames, or frame-dragging, in particular we discuss some aspects of its relative accuracy which can approach one part in a thousand. We then, once again respond to the criticisms of the author of a recent paper about the accuracy in the measurement of frame-dragging with LARES 2. The claims of such a paper are not reproducible in any independent analyses. Indeed, it claims that the accuracy in the test of frame-dragging, which can be reached by the LARES 2 space experiment, is several orders of magnitude larger than previously estimated in a number of papers. Here we show that such a paper is based on a number of significant misunderstandings and conceptual mistakes. Furthermore, it is puzzling to observe that previous papers by the same author contained completely opposite statements about the accuracy which can be reached using two satellites with supplementary inclinations, such as in the LARES 2 space experiment, and in general with laser-ranged satellites
Ultra-high degree spherical harmonic analysis and synthesis using extended-range arithmetic
No full textWe present software for spherical harmonic analysis (SHA) and spherical harmonic synthesis (SHS), which can be used for essentially arbitrary degrees and all co-latitudes in the interval (0°, 180°). The routines use extended-range floating-point arithmetic, in particular for the computation of the associated Legendre functions. The price to be paid is an increased computation time; for degree 3,000, the extended-range arithmetic SHS program takes 49 times longer than its standard arithmetic counterpart. The extended-range SHS and SHA routines allow us to test existing routines for SHA and SHS. A comparison with the publicly available SHS routine GEOGFG18 by Wenzel and HARMONIC SYNTH by Holmes and Pavlis confirms what is known about the stability of these programs. GEOGFG18 gives errors <1 mm for latitudes [-89°57.5?, 89°57.5?] and maximum degree 1,800. Higher degrees significantly limit the range of acceptable latitudes for a given accuracy. HARMONIC SYNTH gives good results up to degree 2,700 for almost the whole latitude range. The errors increase towards the North pole and exceed 1 mm at latitude 82° for degree 2,700. For a maximum degree 3,000, HARMONIC SYNTH produces errors exceeding 1 mm at latitudes of about 60°, whereas GEOGFG18 is limited to latitudes below 45°. Further extending the latitudinal band towards the poles may produce errors of several metres for both programs. A SHA of a uniform random signal on the sphere shows significant errors beyond degree 1,700 for the SHA program SHA by Heck and Seitz.Delft Institute of Earth Observation and Space SystemsAerospace Engineerin
