The purpose of this paper is to provide a discussion of the transformative potential of blended learning in the context of the challenges facing higher education. Based upon a description of blended learning, its potential to support deep and meaningful learning is discussed. From here, a shift to the need to rethink and restructure the learning experience occurs and its transformative potentia...

In this article, an equilibrated gradient recovery error estimator is introduced and analyzed. Regional and global error bounds are established under the equilibrium condition. Furthermore, the error estimator based on the ZZ patch recovery technique is analyzed theoretically. Stability and consistent properties are proved under mild assumptions. All results are valid for arbitrary grids.

Small UUVs have a wide variety of uses including inspection, instrument placement, specimen gathering and salvage. However the uses of these UUVs has been limited by two factors: 1. Cost – UUVs have been traditionally quite expensive, putting them well out of the reach of the traditional marine operator. 2. Wires – Most UUVs trail a cable for power, control, and video back to the operator. The ...

This research develops a gravity-based index of public school competition from private schools within local markets. Proponents of educational reform often call for policies to increase competition between schools. A major hurdle for researchers examining this issue is to determine a workable definition of “competition” by which they can measure the degree of competition within local markets. T...

Decision-feedback equalization (DFE) is explored to reduce inter-symbol interference (ISI) and crosstalks in highspeed backplane applications. In the design of clock and data recovery (CDR) circuit, embedding DFE within phase and frequency detector (PFD) enhances to recover data inherently from distorted input signals and facilitates to provide DFE with recovered clock. With PRBS15 data signali...

Development and management of disaster recovery plan for IT systems are complex, demanding, and yet crucial to an organization success and its competitive position in the marketplace. Due to rapid changes in emerging technologies there is a need for constant improvement and adjustment to disaster recovery plans for IT systems. There are a large number of processes involved in disaster recovery ...

A new frequency offset compensation technique for the MIPI Low Latency Interface (LLI) application is proposed. The proposed clock and data recovery (CDR) circuit has a composite structure of bang-bang and oversampling phase detectors with an offset estimator. Digitally estimated frequency offset is used to determine the gain of the 2nd order digital CDR. An elastic FIFO for the oversampled mul...

The glamor in the IT domain is in the project. Major projects command the attention of the profession; methods for managing, controling and planning projects have been developed and refined; metrics, testing and validation routines, and quality assurance processes are fundamental. On the other hand, much of the day-to-day routine of the IT function is concerned with continuing, rather than proj...

Currently, organizations are increasingly aware of the need to protect their computer infrastructure to maintain continuity of operations. This process involves a number of different concerns including: managing natural disasters, equipment failure, and security breaches, poor data management, inadequate design, and complex/impractical design. The purpose of this article is to delineate how vir...
