In this paper I present the architecture of system that can be used for real time exploration and management of large medical volumetric datasets. The new state of the art solution presented in this paper is an example of visual data management system. System prototype evaluation proved that it is possible to use low-powered (and cheap) up-to-date mobile devices with programmable GPUs as the remote interfaces for exploration of large volumetric medical data. The implementation was done with high-level programming language that enables portability between different hardware models. The lack of lossy compression enables to display high quality medical images visualizations without any simplifications and noises in frequency domain. The prototype of system is capable to remotely render and send to a client (for example cell phone or tablet) rendered data with frequency 30 fps with limited resolution during interaction. One second after the interaction is finished client machine receives full resolution image. The evaluation of the system was performed on volumetric computed tomography angiography image with approximate size 5123 voxels. 相似文献

In 1996, Acadia University became the first Canadian university to adopt a plan of a fully computerized campus. This plan called for progressively equipping each student and faculty member with a personal laptop computer, introducing computer technology into most courses, providing students and faculty with ubiquitous access to the computer network everywhere on the campus, and integrating the technology into the undergraduate curriculum and campus life. In this paper, we describe the context in which this decision was made, discuss the nature of the experience and the involvement of faculty and students in the process, the logistic problems, and impact on faculty and students, successes and disappointments. We also present selected research projects undertaken by faculty within this framework, and outline plans for the future. 相似文献

Effects of extended training (nine sessions, 50 trials each) on two-way avoidance response latencies were studied. For each rat, auditory and visual warning signals (CS) were presented on separate trials, either according to a Gellermann series or in 25-trial blocks. Intermittent presentation of the two kinds of trials yielded shorter latencies and higher levels of avoidance performance in response to the noise CS than in response to the darkness CS. Presentation of trials in blocks revealed stronger response-eliciting properties of stimuli presented during the second half of the session than of those presented during the first half. A significant decrease of avoidance performance in the early portions of the delay period, an index of inhibition of delay, was obtained on auditory trials presented in the second half of the sessions. Results indicate that strong fear of the warning signal is required for inhibition of delay of avoidance responses. 相似文献

This paper addresses the feasibility of higher education in relation to the demands of work life. The research is a comparative study involving four European countries: Sweden, Norway, Poland, and Germany. The research focuses on the view of freshmen, senior students and later graduates in Psychology and Political Science. Data were obtained by semi‐structured interviews, which were subjected to qualitative analyses. The results indicate that higher education, with some exceptions, seems to produce a discipline‐based identity among the students. These findings may be indicative of the value for employability of classical academic generic skills. 相似文献

AbstractThe world of radical football fans across Europe is dominated by anti-system groups. While their sympathies in the west of the continent are mostly leftist, the ultras in the east tend to display right-wing attitudes. Poland makes a particularly interesting case in point, as the most intensive and emotional ideological criticism of the processes of ‘transformation’ and ‘modernisation’ is to be observed at the stadiums. As a result of historical developments, opposition against the system in the country can only be expressed using Catholic–patriotic symbolism, which in the case of collective actions of radical football supporters has produced sociocultural and aesthetic effects not to be found anywhere else in Europe. 相似文献

Facing economic pressure, social tensions, global competition and low public confidence, governments can no longer afford to address increasingly complex and interdependent public goals alone or step back and rely on the markets. Instead, they have to work through networks of state and non-state actors to organize existing resources, knowledge and capabilities in the pursuit of public goals. The new paradigm increasingly relies on Information and Communication Technology (ICT) to connect actors to the network and to build, manage and sustain relationships between them. We refer to such ICT-enabled networks as Government Information Networks. This article serves as an introduction to the current issue of Government Information Quarterly on Government Information Networks. The issue comprises twelve cases of such networks selected from the papers submitted to the 5th International Conference on Theory and Practice of Electronic Governance, ICEGOV2010, held in Beijing, China, October 2010. The article also presents a conceptual framework for public administration networks, and applies the framework to describe, analyze and compare the cases, thus relating the volume to the Public Administration literature. 相似文献

One of the management methods used by the Polish Football Association (PZPN) is management through exclusion. Due to such management, the Association constitutes to a considerable degree the status of individuals and institutions with which it enters into relations. As the essential criteria of these relations, the PZPN adopts utilitarian values, legal and business, diminishing the meaning of sport and moral values. From this perspective, the PZPN efficiently conducts the policy of exclusion it has created, dividing and rejecting those people and institutions who are incapable of contributing to the financial success of the Association. It also imposes various prohibitions on everybody who criticizes the workings of the organization or who accuses it of diminishing or even disregarding the interest of Polish football. For this purpose, the PZPN employs its policy of managing knowledge, which to a significant degree can be considered the propaganda of success. 相似文献

The aim of the study was to compare different types of materials that evoke memories in a sample of Polish seniors. We applied stimuli that referred to the period of reminiscence, that is, to the period between the ages of 10 and 30 in the lives of the investigated individuals. The sample consisted of 121 people between the ages of 65 and 96 years, living in Trójmiasto (the Tri-city), a metropolitan area in northern Poland. The participants were presented with photographs, fragments of popular songs and musical compositions, as well as excerpts from well-known Polish movies. We also applied a memory game as a procedure for stimulating memory in the elderly. The subjects were asked to evaluate the attractiveness of the presented materials on five-point rating scales. It turned out that all of the applied stimuli were assessed positively (the mean ratings were slightly above 4). The most highly valued group of stimuli was the one with musical material. We also observed differences in the evaluation of the applied materials between the group of “younger” seniors (<73 years) and “older” ones (>74 years). The memories evoked under the influence of contact with the presented materials were, in the vast majority of cases, very positive. The obtained data make it possible to infer that materials that evoke memories from the period of reminiscence can improve both the subjects’ memory functions, and their well-being. 相似文献

目的:评估可溶性血管细胞间黏附分子(s VCAM-1)、可溶性细胞间黏附分子(s ICAM-1)、可溶性选择素E和可溶性血栓调节蛋白在血糖控制良好和不受控制的2型糖尿病患者中的水平。创新点:对2型糖尿病患者的血管内皮炎症标记物进行评估。方法:62例糖尿病患者分成两组:第一组包括35个血糖控制良好的糖尿病患者,第二组包括27个未控制血糖并伴有微蛋白尿的糖尿病患者。对照组由25名健康志愿者组成。测定血浆中s VCAM-1、s ICAM-1、可溶性选择素E和可溶性血栓调节蛋白的浓度,同时测定血清肌酐及血浆中空腹血糖和糖化血红蛋白(Hb A1c)的浓度。结论:与血糖控制良好的糖尿病组相比,未控制血糖组具有相对低的ICAM-1水平和更高的VCAM-1水平。未控制血糖组中患者的糖化血红蛋白和ICAM-1之间呈正相关,肾小球滤过率和可溶性选择素E之间呈正相关,而肌酐和ICAM-1之间呈负相关。研究证实2型糖尿病的发病机理中炎症过程的出现与血管内皮功能受损有关。未受控制的高血糖对粘附分子的反向作用表明,在糖尿病的并发症中VCAM-1和ICAM-1具有不同功能。 相似文献
