Architectures and integration of emerging next generation enterprises (NGEs) require a series of complex decisions. This paper describes an intelligent decision support environment that uses patterns, best practices, inferences, and collaboration for enterprise architecture and integration projects. This environment consists of a set of intelligent advisors that collaborate with each other in a...

Distributed software development is increasingly critical to fully utilizing today's distributed computer systems. In the ideal distributed environment, various software components, developed independently on various platforms, are integrated as needed to produce end-user applications that run on a network of machines. Software components are selected oo-the-shelf, i.e. from a repository of tes...

Expressions governing coherence scales of sound passing through a moving packet of nonlinear internal waves in a continental shelf environment are presented. The expressions describe the temporal coherence scale at a point, and the horizontal coherence scale in a plane transverse to the acoustic path, respectively. Factors in the expressions are the wave packet propagation speed, wave packet pr...

In this paper we describe a general-purpose robot programming environment APHRODITE1 built at Columbia University’s Center for Research in Intelligent Systems. The environment is based on a distributed multiprocessor architecture that offers great flexibility and computing strength, and provides a reliable real-time response, while using off-the-shelf software tools. The supporting software tha...

Despite the Amery Ice Shelf (AIS) being the third largest ice shelf in Antarctica, the seasonal variability of the physical processes involved in the AIS-ocean interaction remains undocumented and a robust observational, oceanographic-based basal melt rate estimate has been lacking. Here we use year-long time series of water column temperature, salinity, and horizontal velocities measured along...

Monitoring of ice-shelf and sub-ice-shelf ocean temperatures represents an important component in understanding ice-sheet stability. Continuous monitoring is challenging due to difficult surface access, difficulties in penetrating the ice shelf, and the need for long-term operation of nonrecoverable sensors. We aim to develop rapid lightweight drilling and near-continuous fiber-optic temperatur...

Shelf life of fresh fruits and vegetables is greatly influenced by environmental conditions. Increasing temperature usually results in accelerated loss of quality and shelf-life reduction, which is not physically visible until too late in the supply chain to adjust logistics to match shelf life. A blackberry study showed that temperatures inside pallets varied significantly and 57% of the berri...

The research explored the effect of morphemic analysis awareness on ESL secondary school students’ vocabulary acquisition. The quasi-experimental study was conducted with 100 ESL secondary school students in two experimental groups (inflectional and derivational) and one control group. The students’ vocabulary acquisition was assessed through two measures: Morph-Analysis Test and Morph-Vocabula...

Numerous studies have indicated that the provision of appropriate computer-mediated support to second language (L2) learners results in different vocabulary learning outcomes. However, there is no study available that investigates the transition in their way of learning vocabulary under the influence of technology-based support. This article presents a comparative study that examines the differ...

This study provides a detailed structural glaciological analysis of changes in surface structures on the Larsen B ice shelf on the Antarctic Peninsula prior to its collapse in February–March 2002. Mapped features include the ice-shelf front, rifts, crevasses, longitudinal linear surface structures and meltwater features. We define domains on the ice shelf related to glacier source areas and dem...
