摘要：In this paper the authors describe the design, prototyping and evaluation of SIMpliLife, a framework for mobile phones with the aim of making people’s life easier, providing day-to-day services such as payment, ticketing and information retrieval by means of NFC (Near Field Communication) technology. It was developed via the collaboration between two research labs of sapienza university of rome: the RFID (Radio Frequency Identification) Lab and the Usability and Accessibility Lab (LUA), both belonging to CATTID (Centre for Applications of Teleservices and of Technologies for Innovation in Digital world) research centre. Technically, SIMpliLife is a SIM-based platform for NFC mobile phones that interfaces several applications able to manage the abovementioned services. The high-level User Interface has been developed by means of Smart Card Web Server (SCWS) technology, thus providing enhanced user experience if compared to traditional SIM-based implementations based on SIM Toolkit.

摘要：斯蒂凡诺·乔凡诺尼是当今世界最为著名的设计师之一,他设计的产品并非为了体现社会地位、品味和功用性。他只是想让他的产品使用简单,并希望它们可以贴心备至,给人们带来愉悦和满足感。早餐或午餐时,人们做烹饪以及处理其他事情的时候所需要用到的东西都已经被考虑了进来,情感的纽带瞬间就在使用者与产品间建立了起来。

摘要：噪声是摩擦力引起振动造成音响的一个实例,最近十年多来已经开展了许多研究,这些研究确定集中于简单的制动系统和鉴别‘锁止’的不稳定是造成制动噪声的原因。本文介绍了过去研究的简短文献目录和最近的研究成果。由于锁止对系统动力学的敏感性,制动器设计不能避免模态上的耦合,高的模态不透明度和不确定性与自然频率有关。本文推荐了一种为避免振动滋生的改进方法,它是用集成结构修正转子。

摘要：Since the mid-1980s Chinese calligraphy art has undergone a radical change and has opened itself to experimentation. A vivid debate on CCC (Contemporary Chinese Calligraphy) (Zhongguo xiandai shufa) is involving art critics in China nowadays. WANG Dongling and the modernists think that, despite many changes and influences, we can still refer to the traditional calligraphic lexicon to describe the calligraphic production of contemporary Chinese art. They still remain deeply rooted in the signified system of Chinese writing, even if they break with the strict rules of Chinese classical aesthetic (contamination of Western elements and focus on the stylistic exploration). WANG Nanming and the Avant-garde think that "contemporary calligraphy is not calligraphy yet": It is "anti-calligraphy", annihilates Chinese tradition, rejects the use of legible characters, experiments with new languages and new media within the idiom of international contemporary art. The result is the creation of works of art that could be assimilated to art, expressionism, Conceptual art, Performance art, Contemporary dance, Multimedia art, and even Street art. This paper aims at showing how still valid and extremely productive are both these two theoretical and creative/practical approaches to Chinese calligraphy in China nowadays. They turned the art of calligraphy into a medium for global comprehension and communication.

摘要：This paper describes how to achieve an efficient design and management of a tele-monitoring system of several solar thermal plants. The system will be able to make an analysis that assures a more efficient management of each plant and of the whole system. In the first part of this study, the features of the monitoring system that allows to monitor the operating parameters and to discover the issues before they actually become dangerous for the plant have been identified. The data collected in the different solar thermal systems realized in Italian jails have been analyzed. The results of these elaborations allowed us both to find out some anomalies of functioning of the plants, and to optimize the management of the whole plant in a more efficient way.

摘要：目的:评价选择性环氧化酶2(COX-2)抑制剂和传统的非甾体类抗炎药(NSMDs)在发生血管事件上的风险性。设计:对已发表和未发表随机试验的表格式资料进行荟萃分析,对传统 NSAIDs 的作用进行间接评估。资料来源:资料分别来源于 Medline 和 Embase(1966年1月至2005年4月);食品与药品管理局记录;以及诺华、辉瑞、默克公司的资料。回顾方法:符合以下条件的随机试验入组本研究:一种选择性 COX-2抑制剂与安慰剂比较或一种选择性 COX-2抑制剂与一种传统的 NSAID之间对比;用药持续时间至少4周;包含严重血管事件方面的信息,如心肌梗死、卒中或由于血管事件死亡。各个独立研究者和药厂为本研究提供了有关随机化的病人数目、血管事件的数目以及每个随机化小组中随访的人时(Person time)等信息。结果:在与安慰剂对比的试验中,选择性COX-2抑制剂使严重血管事件发生率增加42%(1.2%/年比0.9%/年;率比1.42,95%可信区间1.13～1.78;P=0.005);不同的选择性 COX-2抑制剂之间没有显著性差异。这主要归因于心肌梗死的风险增加(0.6%/年比0.3%/年;1.86,1.33～2.59;P=0.0003),在其他血管性事件上没有明显的区别。在为时至少1年的试验中(平均2.7年),血管事件的率比是1.45(1.12～1.89;P=0.005)。总的来说,严重血管事件的发生率在选择性 COX-2抑制剂和任何传统 NSAID 之间没有差异(1.0%/年比0.9%/年;1.16,0.97～1.38;P=0.1)。然而,在选择性 COX-2抑制剂与萘普生对比的试验(1.57,1.21～2.03)和选择性COX-2抑制剂与非萘普生类 NSAIDs 相比较的试验之间(0.88,O.69～1.12),我们发现了统计学差异。与安慰剂比较血管事件的总体比率如下:萘普生0.92(0.67～1.26),布洛芬1.51(0.96～2.37),双氯芬酸1.63(1.12～2.37)。结论:选择性 COX-2抑制剂可以中等度增加血管事件的风险性,大剂量布洛芬和双氯芬酸同样具有此作用,但大剂量萘普生不明显增加血管事件的风险性。
