This paper outlines an m-learning solution, ‘Global MedAid’, which aims to provide learning resources and tools for personnel in various roles in disaster or emergency situations. It outlines the development process and presents the design considerations and solutions for developing a cross-platform application combining a wide range of media types for on-line and off-line use, depending on whe...

In this paper we propose X-Global, a novel, almost automatic and semantic system for integrating a set of XML sources. X-Global is parametric w.r.t. the flexibility level against which the integration task is performed; indeed, it can operate on rigid contexts, when two concepts are merged only if they have exactly the same meaning, as well as on flexible and informal situations, when two conce...

the mixture of natural and artificial seismic sources with random distributions cause diffuse wave field with random amplitudes and phases called noise. when noise is analyzed in a long-term process, it contains surface waves which are spread in all directions. thus, ambient noise contains data relevant to the surface waves. in recent years, as broadband seismic networks have been distributed v...

Traditional healthcare environments are extremely complex and challenging to manage, as they are required to cope with an assortment of patient conditions under various circumstances with a wide range of resource constraints. Pervasive healthcare technologies seek to respond to a variety of these pressures by successfully integrating them within existing health care environments. This thematic ...

accurate interpretation of radiographic images is dependent on viewing conditions. recently the number of radiology departments has been increased so it needs to use a workstation for reporting. the aim of this study was assess monitor performance and the effect of viewing conditions on object detection. this investigation aimed to quantify the effects of changes in box brightness and ambient l...

BACKGROUND Assessment of disagreement among multiple measurements for the same subject by different observers remains an important problem in medicine. Several measures have been applied to assess observer agreement. However, problems arise when comparing the degree of observer agreement among different methods, populations or circumstances. METHODS The recently introduced information-based m...

If a regulator is unable to measure firms’ individual emissions, an ambient tax can be used to achieve the socially desired level of pollution. With this tax, each firm pays a unit tax on aggregate emissions. In order for the tax to be effective, firms must recognize that their decisions affect aggregate emissions. When firms behave strategically with respect to the tax-setting regulator, under...
