土地利用-土地覆盖(LULC)制图对于从适当资源分配到政策规划的各种活动都很重要。来自多光谱仪器的免费卫星数据为其在城市规划、自然资源监测和使用中高分辨率卫星数据进行变化分析方面的应用打开了大门。以前,许多研究人员单独使用多光谱仪器,即哨兵-2(10m)、高分-6(16m)和陆地卫星-8(30m)进行土地利用分类,但到目前为止,还没有研究评估这三种仪器在土地利用分类中的效率。因此,本研究使用精度评估和面积估计技术评估了这些仪器的比较。这项研究显示,哨兵-2获得了最高的准确率,但同时也显示出了积攒和贫瘠课程之间的混淆。Landsat-8每小时的精确度最低,非常适合绘制农业区、牧场和林地的地图。最后,高分6号被认为在绘制城市区域地图的可靠结果方面要好得多,因为它显示了良好的结果。在精度评估方面,Sentinel-2的总体精度(OA)为0.89,Kappa(K)为0.85,高分-6的OA为0.80,K为0.79,而Landsat-8的OA为0.76,K为0.70,排在最后。Ar-ea估算结果表明,高分6号(约12856公顷)、陆地卫星8号(约11169公顷)和哨兵2号(约8307公顷)分别估算了集结级的准确面积。据观察,在基于Sentinel-2的分类中,城市地区被误分类为附近城市地区的贫瘠地区。最后得出结论,土地利用效率主要取决于研究目的。对于林地、农业、牧场和贫瘠土地LULC等级,Sentinel-2和高分-6均显示出有希望的结果,而只有水等级Geofen-6的结果似乎相当准确。最后,对于堆积区,本研究表明,与哨兵2号和陆地卫星8号相比,高分6号显示出了有希望的结果。

Spindle cell carcinoma also known as sarcomatoid carcinoma is a rare highly aggressive tumor which is histologically different from squamous cell ca and mesenchymal cancers. Only hands full of cases have been reported in literature since 1957 and hence no proper treatment protocol has been devised yet. We present such a case of thirty-four-year-old female who presented with spindle cell carcinoma of the maxilla at our department and was treated with extensive surgery followed by chemotherapy and radiation therapy. Spindle cell carcinoma is generally associated with poor prognosis and hence literature supports use of post operative Chemo and Radiotherapy for better result and decrease chance of local recurrence.

近年来,巴基斯坦和中国在很多领域都有密切的交流与合作,因此,对于巴基斯坦的学习者来说,在中国学习有利于两国文化交流和进一步的合作。此外,中国政府向巴基斯坦学习者提供的奖学金额度逐年增加,吸引了众多巴基斯坦年轻人到中国留学。大多数巴基斯坦学习者在中国学习的专业都是汉语,其他专业相对较少。随着学习者的增加,影响巴基斯坦学习者学习汉语的原因也有很多,原因之一是巴基斯坦学习者学习汉语的态度。本文中,笔者使用问卷调查法,访谈法及观察法来了解巴基斯坦学习者学习汉语的态度。在八月份的时候,笔者给在中国和在巴基斯坦的学习者发放了调查问卷,并收集了数据,还采访了许多在线上上课的学习者以及在巴基斯坦不同大学和在孔子学院学习的学习者。除此之外,笔者还到几个大学观察巴基斯坦汉语学习者上汉语课。通过对巴基斯坦汉语学习者态度方面的全面考察,笔者了解了影响学习者学习汉语态度的三个主要因素。影响学习者的一个原因是经济来源问题,他们的收入对他们学习汉语的态度有很大影响;第二个因素是巴基斯坦学习者的专业不同,中文专业的学习者和其他专业的学习者对汉语的态度不同;另一个对巴基斯坦学习者影响最大的原因是环境,因为在巴基斯坦没有良好的目的语环境,所以这对他们的态度有很大影响,甚至有些学习者因此而放弃了学习中文。笔者就以上影响原因和因素进行了分析和探讨,总结出巴基斯坦汉语学习者学习态度受到影响的主要原因并给出了解决方法和一些可行性建议。论文中,笔者在学习者、教师以及学习材料等方面都提出了建议。笔者给了学习者建议主要有:(1)争取稳定的经济来源保障学习生活,(2)正确对待本专业与汉语学习之间的关系,(3)努力适应学习环境的变化;其次,给教师的建议主要有:(1)遵循教学原则,选择合适的教学方法,(2)提升自身专业知识和技能。最后,笔者针对课堂教材和课外读本存在的问题也提出了具体建议。例如,笔者建议老师在课外可以更多的提供故事性强、内容丰富和情节吸引人的课外读本,例如中华成语故事、寓言故事、民间神话等,尤其是带拼音和彩绘的儿童故事书在巴基斯坦汉语学习者眼中是最受欢迎的课外读本之一等。

语义Web虽发展缓慢但却稳步发展。本体作为语义Web的核心部分受到了广泛关注并且还需寻找一些新的技术来实现本体的发展。为了使语义Web的研究切实可行,毫无疑问,本体映射和映射的评价是我们最很重要的一个研究方向。当前可行的本体映射技术并未充分考虑本体的语义,并且一般都是采用传统的技术来计算本体之间的相似度,因此匹配结果并没有达到实际预期效果。传统技术使用多策略映射技术和通过给每一种映射策略分配固定的权值的方法来合并映射结果,而事实上语义本体的权值应该通过其语义来决定权值的分配。在本文中我们提出了一种通过上下文语义来设置权值和计算相似度的条件信息量的概念。评价映射结果的算法与本体映射一样重要,不同时期出现了不同的映射评价的技术,其中查全率和查准率是最常用的技术。和传统的映射技术一样,传统的评价技术也没考虑本体的语义。本文提出了纯粹的语义查准率和查全率的一个评价框架,这一框架确保评价方法是纯语义的。我们将把这个框架与一些基本应用的评价方法相结合,将其应用实际操作中。

Ionosphereic foF2 variations are very sensitive to the seismic effect and results of ionospheric perturbations associated with earthquakes seem to very hopeful for short-term earthquake prediction. On January 18,2011 at 20: 23 UT a great earthquake( M = 7. 2)occurred in Dalbandin( 28. 73° N,63. 92° E),Pakistan. In this study,we have tried to find out the features of pre-earthquake ionospheric anomalies by using the hourly day time( 08. 00 a. m.- 05. 00 p. m.) data of critical frequency( foF2) obtained by three vertical sounding stations installed in Islamabad( 33. 78°N,73. 06°E),Multan( 32. 26°N,71. 51°E) and Karachi( 24. 89° N,67. 02° E), Pakistan. The results show the significant anomalies of foF2 in the earthquake preparation zone several days prior to the Dalbandin earthquake. It is also observed that the amplitude and frequency of foF2 anomalies are more prominent at the nearest station to the epicenter as compared to those stations near the outer margin of the earthquake preparation zone. The confidence level for ionospheric anomalies regarding the seismic signatures can be enhanced by adding the analysis of some other ionospheic parameters along with critical frequency of the layer F2.
