The present work describes software SOLEEC (copyright 03-2012-070510302900-01 Mexico), a numerical tool for PTC (parabolic trough collector) designing. Software SOLEEC is divided into two main parts. The first one allows solar resource assessment for a specific place on the Earth. The computation and assessment can be done for a specific day on the year, for one specific month and the monthly averages along the year. The last one gives annual charts such as: solar constant, Earth declination, insolation hours, and sunrise and sunset hours. The second part has four different execution options for PTC designing, that is, using options one and two user can get five different designs based on receiver outer diameter evaluating solar radiation data along the full year or only one solar radiation value (monthly), on the other hand options three and four were developed to compute the thermal evaluation for an operating collector for twelve solar radiation values (annually) or a specific month computation, respectively. 相似文献

Locomotion scores are used for lameness detection in dairy cows. In research, locomotion scores with 5 levels are used most often. Analysis of scores, however, is done after transformation of the original 5-level scale into a 4-, 3-, or 2-level scale to improve reliability and agreement. The objective of this study was to evaluate different ways of merging levels to optimize resolution, reliability, and agreement of locomotion scores for dairy cows. Locomotion scoring was done by using a 5-level scale and 10 experienced raters in 2 different scoring sessions from videos from 58 cows. Intra- and interrater reliability and agreement were calculated as weighted kappa coefficient (κw) and percentage of agreement (PA), respectively. Overall intra- and interrater reliability and agreement and specific intra- and interrater agreement were determined for the 5-level scale and after transformation into 4-, 3-, and 2-level scales by merging different combinations of adjacent levels. Intrarater reliability (κw) ranged from 0.63 to 0.86, whereas intrarater agreement (PA) ranged from 60.3 to 82.8% for the 5-level scale. Interrater κw = 0.28 to 0.84 and interrater PA = 22.6 to 81.8% for the 5-level scale. The specific intrarater agreement was 76.4% for locomotion level 1, 68.5% for level 2, 65% for level 3, 77.2% for level 4, and 80% for level 5. Specific interrater agreement was 64.7% for locomotion level 1, 57.5% for level 2, 50.8% for level 3, 60% for level 4, and 45.2% for level 5. Specific intra- and interrater agreement suggested that levels 2 and 3 were more difficult to score consistently compared with other levels in the 5-level scale. The acceptance threshold for overall intra- and interrater reliability (κw and κ ≥0.6) and agreement (PA ≥75%) and specific intra- and interrater agreement (≥75% for all levels within locomotion score) was exceeded only for the 2-level scale when the 5 levels were merged as (12)(345) or (123)(45). In conclusion, when locomotion scoring is performed by experienced raters without further training together, the lowest specific intra- and interrater agreement was obtained in levels 2 and 3 of the 5-level scale. Acceptance thresholds for overall intra- and interrater reliability and agreement and specific intra- and interrater agreement were exceeded only in the 2-level scale. 相似文献

Nowadays, it is impossible to imagine daily life without satellite communication and satellite navigation. Many applications and services use communication and satellite navigation technologies in order to facilitate daily life. This article focuses on location-based services (LBS) provided by TeleConsult Austria which can be used in different fields and circumstances. These services contribute significantly to personal security and increased mobility. 相似文献

The system presented here shows the feasibility of modeling the knowledge involved in a complex musical activity by integrating
sub-symbolic and symbolic processes. This research focuses on the question of whether there is any advantage in integrating
a neural network together with a distributed artificial intelligence approach within the music domain. The primary purpose
of our work is to design a model that describes the different aspects a user might be interested in considering when involved
in a musical activity. The approach we suggest in this work enables the musician to encode his knowledge, intuitions, and
aesthetic taste into different modules. The system captures these aspects by computing and applying three distinct functions:
rules, fuzzy concepts, and learning. As a case study, we began experimenting with first species two-part counterpoint melodies.
We have developed a hybrid system composed of a connectionist module and an agent-based module to combine the sub-symbolic
and symbolic levels to achieve this task. The technique presented here to represent musical knowledge constitutes a new approach
for composing polyphonic music.

Investigated whether stereotypic knowledge would influence social perception in a more realistic setting. In Exp I, 96 undergraduates watched a videotape of a target woman identified either as a waitress or a librarian; Ss more accurately remembered features of the woman that were consistent with their prototype of a waitress (librarian) than features that were inconsistent. The prototype-consistency effect did not interact with the delay time before recognition memory was assessed. In Exp III, 56 Ss learned the occupational information either before or after watching the tape. The prototype-consistency effect from Exp I was replicated. In addition, knowing the target's occupation while watching her led to increased accuracy for both consistent and inconsistent information. The probable role of both encoding and retrieval processes in contributing to this effect is noted. Perceivers' stereotypic prior knowledge influenced their memory of a target person's behavior even in a realistic person-perception situation. Conditions that favor the memorability of consistent vs inconsistent information are discussed. (28 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Estimated verbally and numerically the chances that specific events will occur using 6 analysts. 60 decision makers used each type of estimate to make binary-choice decisions and to bid for lotteries based on the events. The usual reversal of preference between choice and bidding procedures was found in the numerical condition, but the frequency of preference reversals was significantly reduced in the verbal condition. This reduction occurred because risk aversion was reduced in choice when verbal estimates were given, whereas bidding was unaffected by presentation mode. The pattern of results was predicted by and supports the hypothesis that the relative importance given to the dimensions of a prospect depends on the form in which the information is displayed.

Data from a random cohort of residents in a 2-county area were used to determine the stability in 2 major dimensions of childhood behavior between 2 generations. The 1st generation was assessed at mean age 7, and their offspring were assessed at age 2 years. Measures were used in latent-variable structural equation models to test the hypotheses. Strong stability in these behavior patterns in the 1st generation was shown between early childhood and a reassessment 8 years later. There was a significant stability between generations in the inhibited behavior pattern but not in the difficult pattern. This relationship was stronger when parents had been assessed at an age closer to that of their toddler offspring. Findings are consistent for mother–offspring, father–offspring, and daughter and son subsamples. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
