FIS Freestyle Skiing World Cup Moguls Idre 2022 Live Stream WATCH LIVE ONLINE HERE Long months of anticipation are over as the FIS Freestyle Ski World Cup season is finally slated to get into high gear with the opening moguls and aerials competitions this upcoming weekend in Ruka. This year marks the 13th consecutive time the FIS Freestyle season has began in the far north of Finland, and based on the consistent success of the Freestyle Opening Ruka World Cup event it’s fair to expect another set of excellent competitions under the lights in Ruka to kick of the 2022/23 campaign. These data have been cleaned and integrated with data from COVID-19-TweetIDs and from other sources (e.g., PMC). The result was dataset of 500,314 unique articles along with relevant metadata (e.g., the underlying citation network). We utilized this dataset to produce, for each article, the values of the following impact measures:dfhgf Influence: Citation-based measure reflecting the total impact of an article. This is based on the PageRank3 network analysis method. In the context of citation networks, it estimates the importance of each article based on its centrality in the whole network. This measure was calculated using the PaperRanking (https://github.com/diwis/zdhPaperRanking) library4.dgfdhfd The washers dataset features 70 defective parts. The gears and screws datasets feature 35 defective, 35 intact and several hundred unannotated parts. Some defects, such as notches and holes, are visible in most images (illuminations) with intensity and texture variations among them, while others, such as scratches, are only visible in a few.fghgj We split the datasets into train and test sets. The train sets contain 32 samples, and the test set 38 samples. Each sample comprises 108 images (each captured under a different illumination angle), an automatically extracted foreground segmentation mask, and a hand-labeled defect segmentation mask.fghgfj This dataset is challenging mainly because: each raw sample consists of 108 gray-scale images of resolution 512×512 and therefore takes 27MB of space; the metallic surfaces produce many specular reflections that sometimes saturate the camera sensors; the annotations are not very precise because the exact extent of defect contours is always subjective; the defects are very sparse also in the spatial dimensions: they cover only about 0.2% of the total image area in gears, 0.8% in screws, and 1.4% in washers; this creates an unbalanced dataset with a highly skewed class representation. gfhj The dataset is organized as follows: each sample resides in the Test, Train, or Unannotated directory; each sample has its own directory which contains the individual images, the foreground, and defect segmentation masks; each image is stored in 8-bit greyscale png format and has a resolution of 512 x 512 pixels; Image file names are formatted using three string fields separated with the underscore character: prefix_sampleNr_illuminationNr.png, where the prefix is e.g. washer, the sampleNr might be a three-digit number 001, and the illuminationNr is formed of 3 digits, first corresponding to the elevation index (1 - highest angle, 9 - lowest angle), and the additional two corresponding to the azimuth index (01-12). Each dataset contains light_vectors.csv, which contains the illumination angles (in lexicographic order of the illuminationNr), and light_intensities.csv that contains the numbers corresponding to the light intensity on the scale from 0 to 127. Please, be aware, that the azimuth angles were not calibrated and might be a few degrees misaligned.fdhfgj These data have been cleaned and integrated with data from COVID-19-TweetIDs and from other sources (e.g., PMC). The result was dataset of 500,314 unique articles along with relevant metadata (e.g., the underlying citation network). We utilized this dataset to produce, for each article, the values of the following impact measures:sdgfdfhfggh Influence: Citation-based measure reflecting the total impact of an article. This is based on the PageRank3 network analysis method. In the context of citation networks, it estimates the importance of each article based on its centrality in the whole network. This measure was calculated using the PaperRanking (https://github.com/diwifss/PaperRanking) library4.sddfghfggd Influence_alt: Citation-based measure reflecting the total impact of an article. This is the Citation Count of each article, calculated based on the citation network between the articles contained in the BIP4COVID19 dataset.sddggf safs Popularity: Citation-based measure reflecting the current impact of an article. This is based on the AttRank5 citation network analysis method. Methods like PageRank are biased against recently published articles (new articles need time to receive their first citations). AttRank alleviates this problem incorporating an attention-based mechanism, akin to a time-restricted version of preferential attachment, to explicitly capture a researcher's preference to read papers which received a lot of attention recently. This is why it is more suitable to capture the current "hype" of an article.asdfujsgdg Colour Science for Python Colour is an open-source Python package providing a comprehensive number of algorithms and datasets for colour science. sdg It is freely available under the New BSD License terms.uiuol Colour is an affiliated project of NumFOCUS, a 501(c)(3) nonprofit in the United States Draft Release Notes The draft release notes of the develop branch are available at this url.uiu Sponsors We are grateful 💖 for the support of our sponsors.

This is based on the RAM6 citation network analysis method. Methods like PageRank are biased against recently published articles (new articles need time to receive their first citations). RAM alleviates this problem using an approach known as "time-awareness". This is why it is more suitable to capture the current "hype" of an article. This measure was calculated using the PaperRanking (https://github.com/diwis/PaperRanking) library4.sfbsdf Social Media Attention: The number of tweets related to this article. Relevant data were collected from the COVID-19-TweetIDs dataset. In this version, tweets between 23/6/22-29/6/22 have been considered from the previous dataset.ftgujyol We provide five CSV files, all containing the same information, however each having its entries ordered by a different impact measure. All CSV files are tab separated and have the same columns (PubMed_id, PdfMC_id, DOI, influence_score, popularity_alt_score, popularity score, influence_alt score, tweets count).yjytik Rich offline experience, periodic background sync, push notification functionality, network requests control, improved performance via requests caching are only a few of the functionalities provided by the Service Worker (SW ) API. This new technology, supported by all major browsers, can significantly improve users’ experience by providing the publisher with the technical foundations that would normally require a native application. Albeit the capabilities of this new technique and its important role in the ecosystem of Progressive Web Apps (PWAs), it is still unclear what is their actual purpose on the web, and how publishers leverage the provided functionality in their web applications. In this study, we shed light in the real world deployment of SWs, by conducting the first large scale analysis of the prevalence of SWs in the wild.huiuop We see that SWs are becoming more and more popular, with the adoption increased by 26% only within the last 5 months. Surprisingly, besides their fruitful capabilities, we see that SWs are being mostly used for In-Page Push Advertising, in 65.08% of the SWs that connect with 3rd parties. We highlight that this is a relatively new way for advertisers to bypass ad-blockers and render ads on the user’s displays natively.ik
2022年芬兰卢卡国际雪联(FIS)自由式滑雪世界杯雪上技巧(Moguls)赛事直播:敬请观看
经过数月期待,国际雪联自由式滑雪世界杯新赛季终于将在本周末于芬兰卢卡拉开帷幕,揭幕战将包含雪上技巧与空中技巧(Aerials)两项赛事。今年是该系列赛事连续第13年在芬兰北部偏远地区举办,基于卢卡自由式滑雪开幕世界杯赛事一贯的高水准,我们有理由期待本届赛事将在卢卡的赛场灯光下奉上精彩对决,正式开启2022/23赛季征程。
本数据集已完成清洗,并与COVID-19-TweetIDs数据集及其他来源(如PubMed Central(PMC))的数据进行了整合,最终得到包含500314篇独特学术文章及相关元数据(如底层引用网络)的数据集。
我们基于该数据集为每篇文章计算了以下影响力度量指标:
1. 影响力(Influence):基于引用网络的文章总影响力度量方法,依托PageRank网络分析算法实现。在引用网络语境下,该指标通过文章在整体网络中的中心性评估其重要性,计算过程使用PaperRanking库(https://github.com/diwis/zdhPaperRanking)完成。
2. 替代影响力(Influence_alt):同样基于引用网络的文章总影响力度量方法,即每篇文章的引用计数,基于BIP4COVID19数据集中文章间的引用网络计算得出。
3. 热度(Popularity):基于引用网络的文章当前影响力度量方法,依托AttRank引用网络分析算法实现。诸如PageRank这类传统方法会对新发表文章存在偏见(新文章需要时间获得首次引用),而AttRank通过引入注意力机制(类优先连接的时间限制版本),显式捕捉研究者对近期受关注论文的偏好,因此更适合衡量文章当前的“热度”。
4. 替代热度(Popularity alternative):另一种基于引用网络的文章当前影响力度量方法(该指标是BIP4COVID19数据集26版本前的基础热度度量),依托RAM引用网络分析算法实现。与PageRank类似,RAM通过“时间感知”机制缓解了对新文章的偏见,同样适合衡量文章当前的“热度”,计算过程使用PaperRanking库(https://github.com/diwis/PaperRanking)完成。
5. 社交媒体关注度(Social Media Attention):与文章相关的推特(Tweets)数量,相关数据采集自COVID-19-TweetIDs数据集。本版本数据集中选取了2022年6月23日至6月29日期间的推文数据。
本次共提供5个CSV格式文件,所有文件包含相同的字段信息,但各自依据不同的影响力度量指标进行排序。所有CSV文件均采用制表符分隔,字段统一为:PubMed_id、PdfMC_id、DOI、influence_score、popularity_alt_score、popularity_score、influence_alt_score、tweets_count。
垫圈数据集包含70个缺陷零件。齿轮数据集与螺丝数据集则各包含35个缺陷零件、35个完好零件,以及数百个未标注零件。部分缺陷(如缺口与孔洞)在多数光照图像中均可被观测到,且不同图像间存在强度与纹理差异;而另一部分缺陷(如划痕)仅在少量图像中可见。
我们将数据集划分为训练集与测试集:训练集包含32个样本,测试集包含38个样本。每个样本由108张图像(每张图像在不同光照角度下拍摄)、自动提取的前景分割掩码,以及人工标注的缺陷分割掩码组成。
该数据集的挑战性主要体现在以下几点:
1. 每个原始样本包含108张分辨率为512×512的灰度图像,单样本占用空间达27MB;
2. 金属表面会产生大量镜面反射,有时甚至会使相机传感器过曝;
3. 标注精度有限,因为缺陷轮廓的精确范围通常具有主观性;
4. 缺陷在空间维度上极为稀疏:齿轮数据集的缺陷仅占图像总面积的约0.2%,螺丝数据集为0.8%,垫圈数据集为1.4%,这导致数据集类别分布高度不平衡。
数据集的组织形式如下:
每个样本存放于Test、Train或Unannotated目录下;每个样本拥有独立的子目录,其中包含单独的图像文件、前景分割掩码以及缺陷分割掩码;所有图像均以8位灰度PNG格式存储,分辨率为512×512像素。
图像文件名采用下划线分隔的三个字符串字段格式:prefix_sampleNr_illuminationNr.png,其中prefix例如为washer,sampleNr为三位数字(如001),illuminationNr由三位数字组成:第一位对应仰角索引(1为最高仰角,9为最低仰角),后两位对应方位角索引(01至12)。
每个数据集均包含light_vectors.csv与light_intensities.csv两个文件:前者按illuminationNr的字典序存储光照角度,后者存储0至127区间内的光照强度数值。请注意,方位角未经过校准,可能存在数度的偏差。

服务工作线程(SW)API可提供丰富的离线体验、周期性后台同步、推送通知功能、网络请求控制以及基于请求缓存的性能优化等多项功能。这项得到所有主流浏览器支持的新技术,为开发者提供了原本仅原生应用才具备的技术基础,可显著提升用户体验。尽管这项新技术及其在渐进式Web应用(PWAs)生态中的重要作用已得到广泛认可,但目前仍不清楚其在Web环境中的实际用途,以及发布者如何在Web应用中利用其提供的功能。
本研究针对服务工作线程在真实场景中的部署展开了首次大规模分析,以此阐明其实际应用情况。研究发现,服务工作线程的普及率正不断提升,仅在过去5个月内其采用率就增长了26%。令人意外的是,尽管服务工作线程拥有诸多实用功能,但在与第三方建立连接的服务工作线程中,65.08%的线程被用于页面内推送广告——这是广告商绕过广告拦截器、直接在用户设备上原生展示广告的一种相对新颖的方式。
