This study sought to evaluate the effectiveness of a peer feedback strategy in asynchronous online discussions. Specifically, this exploratory study examined the impact of peer feedback in online discussions on students' perceived and actual critical thinking skills in terms of receiving and providing peer feedback Participant interviews and pre and post surveys targeting critical thinking skil...

The research presented here studied thirty-three groups of student volunteers over a period of three weeks while the groups performed a series of teamwork tasks. To investigate the viability of Web-based group support tools for asynchronous learning networks, student volunteers from four widely distributed universities were assigned to one of four experimental conditions. The conditions are; 2 ...

This paper presents a formal verification for a bit-serial hardware architecture. The developed architecture bases on the combination of different design paradigms and requires sophisticated design optimizations. The recently patented synchronous bit-serial pipelined architecture, which we investigate in this paper, is comprised of synchronous and systematic bit-serial processing operators with...

In vector multiprocessor systems, collisions in the interconnection network and conflicts in the memory modules are the main causes of the performance degradation. In this work we use a synchronized interconnection network, and propose an interleaved storage scheme and an out-of-order access to the elements of the stream that allow conflict-free access. The streams are generated by the differen...

2 Sun Microsystems 3 Work done while a student at Stanford University This paper describes an approach for handling intermittent connectivity between mobile clients and network-resident applications, which we call zippering. When the client connects with the application, communication between the client and the application is synchronous. When the client intermittently connects with the applica...

In this paper I’m proposing a novel idea for designing and developing an embedded system which gives a solution for testing various serial communication interfaces of target board. This work reduces total system debugging time since it creates an independent platform, which helps the testing engineers to check their board before the entire completion i.e. it provides the developers an environme...

In this paper an efficient architecture of a reconfigurable bit-serial polynomial hasis multiplier for Galois field GF(Z”’), where I<m= is proposed. The value of the field degree m can be changed and the irreducible polynomial can be configured and programmed. Comparing with previous designs, the advantages of.the proposed architecture are (i) the high order of flexibility, which allows an easy...

This paper studies the time required to solve the session problem in a new timing model, called the periodic model, for shared memory distributed systems. In the periodic model, each process runs at a constant unknown rate and di erent processes may run at di erent rates. Nearly matching upper and lower bounds are shown on the time complexity of the session problem in the model. These bounds in...

This paper is an investigation of the nature and the value of asynchronous on-line discussion within small groups of learners. It draws on research into the experiences of adult learners within short courses and formal post degree settings in which it was found that learners valued on-line discussion but experienced several constraints on participation. It is suggested that the nature of the me...
