This paper describes a scheme of adaptive advising students on how much time they should spend on traversing the course network. The scheme is based on the notion of critical path embodied in the network. While web-based online learning emphases student’s initiative in managing his own learning, experiences tell us that some students are always at the risk of being lost in the cyber campus. If ...

This paper presents an approach to extracting a path line oriented topological segmentation for periodic 2D timedependent vector fields. Topological methods aiming in capturing the asymptotic behavior of path lines rarely exist because path lines are usually only defined over a fixed time-interval, making statements about their asymptotic behavior impossible. For the data class of periodic vect...

A high speed word level finite field multiplier in F2m using redundant representation is proposed. For the class of fields that there exists a type I optimal normal basis, the new architecture has significantly higher speed compared to previously proposed architectures using either normal basis or redundant representation at the expense of moderately higher area complexity. One of the unique fe...

We consider the problem of dynamically allocating scarce resources to multiple projects in a project-oriented production system such as a naval shipyard. We formulate axioms governing the relationship between resource allocations and work progress of aggregate project activities, from which a model of project execution is derived. This model is more accurate than models which represent aggregat...

Forecasting Project Progress and Early Warning of Project Overruns with Probabilistic Methods. (December 2007) Byung Cheol Kim, B.S., Seoul National University; M.S., Seoul National University Chair of Advisory Committee: Dr. Kenneth F. Reinschmidt Forecasting is a critical component of project management. Project managers must be able to make reliable predictions about the final duration and c...

This paper presents a fault-tolerant algorithm for the QR factorization of general matrices. It relies on the communication-avoiding algorithm, and uses the structure of the reduction of each part of the computation to introduce redundancies that are sufficient to recover the state of a failed process. After a process has failed, its state can be recovered based on the data held by one process ...

The assembly line balancing problem is a non deterministic polynomial type planning problem for mass production. Layout design changes constitute a major decision that yields investment for assembly operations and numerous heuristics have been reported in the literature for solving the line balancing problems. U-shaped assembly layout offers several benefits over traditional straight-line layou...

In this paper, a unified sequential architecture for 8-point discrete cosine transform and its inverse is described. The architecture is based on rescheduled constant geometry algorithms, which are mapped onto a one-dimensional structure with the aid of vertical projection. The resulting modular architecture can be efficiently pipelined since arithmetic units are removed from the critical path....
