M-learning is an important role in e-learning environment by mobile device. However, in Taiwan junior high education, few research was to develop an m-learning system on the geography curriculum. Geography courses are quite indispensable. The sense of direction of training is one of the first studies in Taiwan junior high education of geography curriculum; however, many students’ sense of direc...
Results from a series of Goddard Institute for Space Studies (GISS) General Circulation Models (GCMs) are used to assess climate variability in the pre-anthropogenic Holocene, the interval following the end of the last glacial beginning roughly 11.5 kyr BP. In particular, we focus on the forced aspects of this variability. The principle forcings are orbital, solar, volcanic and events (such as ...
A new aerosol microphysical module MATRIX, the Multiconfiguration Aerosol TRacker of mIXing state, and its application in the Goddard Institute for Space Studies (GISS) climate model (ModelE) are described. This module, which is based on the quadrature method of moments (QMOM), represents nucleation, condensation, coagulation, internal and external mixing, and cloud-drop activation and provides...
GISs are moving away from a system for experts to a more widely-used tool for answering spatial-related questions. The dawn of new technologies on the horizon, such as telecommunication, mobile Internet, and handheld computing devices, offers new chances to the everyday use of geoinformation. However, existing approaches to mobile visualisation of geoinformation mostly have a commercial backgro...
Alien species can exert negative environmental and socio-economic impacts. Therefore, administrations from different sectors are trying to prevent further introductions, stop the spread of established species, and apply or develop programs to mitigate their impact, to contain the most harmful species, or to eradicate them if possible. Often it is not clear which of the numerous alien species ar...

Qualitative spatial reasoning is important for many spatial in formation systems including GISs It is based on the manipulation of qual itative spatial relationships and is used to infer spatial relationships which are not stored explicitly in the Geographic DataBase GDB to answer spa tial queries given partial spatial knowledge and to maintain the consistency of the GDB This paper compares the...
OBJECTIVES To test retrospectively the ability of four freely available rules-based expert systems to predict short- and medium-term virological outcome following an antiretroviral treatment switch in pre-treated HIV-1 patients. METHODS The HIV-1 genotype interpretation systems (GISs) HIVdb, ANRS, Rega and AntiRetroScan were tested for their accuracy in predicting response to highly active an...
\Optimal wire sizing and buuer insertion for low power and a generalized delay model," in Proc. 17 problems are solved in the context of simultaneous device and wire sizing optimization for deep submicron designs. Experiments show that our LR-based optimization algorithm is very eeective and extremely eecient. Up to 16.5% delay reduction is observed when compared with previous work based on the...
