基于实时新闻分析的馆藏资源推荐方法研究

如何在信息时代增加馆藏资源的可见度,提高馆藏资源的利用率,是一个急需研究和解决的问题。实时新闻和图书馆馆藏资源间的连接可以提高图书馆馆藏资源的可见度,增加图书馆馆藏资源的利用率,为用户提供丰富、全面的阅读资料和专业知识,帮助用户形成全面、深入阅读和思考的良好习惯。基于快数据处理技术的实时新闻分析和馆藏资源推荐框架,通过分析网络实时新闻获取用户感兴趣的话题,应用快数据处理技术、潜在语义分析、非负矩阵分解、权重矩阵分解等方法对数据进行语义分析和处理,对图书馆馆藏资源进行相关话题的分类和推荐。对OCLC的百万数据集和雅虎新闻的分析和实验表明,这种资源推荐框架和方法有较好的应用效果。图2。表1。     

复杂背景下运动目标检测与实时跟踪

为准确追踪复杂背景下视频序列待处理目标的位置,提出一种基于互相关信息和Mean Shift相结合的目标追踪算法。将待处理帧和背景帧图像从RGB空间转化为GRAY空间,利用背景剪除法获取待匹配帧的基准图像,对基准图像用快速傅里叶变换得到基准图象和模版图像的相关性,结合Mean Shift最终确定目标图像的位置。实验结果表明,该方法在遮挡、环境干扰等复杂情况下均能稳定有效地追踪目标。

兴酣落笔摇五岳 诗成啸傲凌沧州——论李白诗歌的艺术特色

在中国诗歌史上,李白是最具独特性格的伟大诗人之一,他的诗艺术风格是以自然为宗,飘逸豪放,修辞手法的运用更是独具特色。他的诗裁体多样,题材广泛,并且都具有鲜明的艺术特色。他的一生,把禀赋所具有的自信、天真、狂傲、仗义等情性发挥得淋漓尽致,酣畅自如,同代诗人不可与之相比。     

Coping with handover effects in video streaming over cellular networks

The 3rd generation partnership project (3GPP) has defined the protocols and codecs for implementing media streaming services over packet-switched 3G mobile networks. The specification is based on IETF RFCs on audio/video transport. It also adds new features to achieve better adaptation to the mobile network environment. In this paper, we propose an algorithm for handover detection and fast buffer refill that is based on the existing feedback and signaling mechanisms. The proposed algorithm refills the receiver buffer at a faster pace during a limited time frame after a hard handover is detected in order to achieve higher video quality.     

Cricket fast bowling performance and technique and the influence of selected physical factors during an 8-over spell

The aims of this study were to determine the influence of an 8-over spell on cricket fast bowling technique and performance (speed and accuracy), and to establish the relationship of selected physical capacities with technique and performance during an 8-over spell. Fourteen first-grade fast bowlers with a mean age of 23 years participated in the study. Physical capacities assessed were abdominal strength, trunk stability, selected girth and skinfold measures. During the delivery stride, bowlers were filmed from an overhead and lateral perspective (50 Hz) to obtain two-dimensional data for transverse plane shoulder alignment and sagittal plane knee joint angle respectively. Ball speed was measured by a radar gun and accuracy by the impact point of each delivery on a zoned scoring target at the batter's stumps. Shoulder counter-rotation did not change significantly between overs 2 and 8 for all bowlers, but was significantly related to a more front-on shoulder orientation at back foot impact. When the front-on fast bowlers ( n = 5) were isolated for analysis, shoulder counter-rotation increased significantly between overs 2 and 8. Ball speed remained constant while accuracy showed some non-significant variation during the spell. Shoulder counter-rotation was significantly related to accuracy scores during the second half of the 8-over spell. Chest girth and composition and body composition were significantly related to ball release speed at various times during the spell.
