The research on Response to Intervention (RtI) with secondary students is scant; however, a recently conducted, multiyear, large-scale implementation of RtI with middle-school students provides findings that inform practices and future directions for research. This article provides an overview of the findings from each of the 3 years of an intensive, tiered reading intervention with middle-scho...

The risk associated to the action of nanoplastics as carriers environmental pollutants was investigated by a multi-tiered approach.

Tiered wireless sensor networks (WSNs) have many advantages over traditional WSNs. However, they are vulnerable to security attacks, especially the attacks to the storage nodes that buffer and process the data readings from sensors. In this paper, we propose a secure data collection protocol SDC to support timebased queries in tiered WSNs. With small overhead introduced to data communication, S...

This study presented a transformation approach of Model Driven Architecture for 3-tiered applications. Mapping rules from computation independent model to platform independent model and from platform independent model to platform specific model were developed. This approach was demonstrated using an on-line bookshop application. With this approach, the weak link of Model Driven Architecture, tr...

Most current solutions for Web Based Instruction (WBI) use a centralized management model and a proprietary internal representation. The AVANTE Architecture is a WBI environment assembled using CORBA distributed components, implementing core services such as course management, user authentication, collaborative work, database access, presentation, and others. The AVANTE components conform to a ...

Parallel computing on interconnected workstations is becoming a viable and attractive proposition due to the rapid growth in speeds of interconnection networks and processors. In the case of workstation clusters, there is always a considerable amount of unused computing capacity available in the network. However, heterogeneity in architectures and operating systems, load variations on machines,...
