Work In Progress- Understanding Discomfort: Student Responses To Self-Direction, Jonathan Stolk, Mark Somerville, John B. Geddes, Rob Martello Jul 2012

Work In Progress- Understanding Discomfort: Student Responses To Self-Direction, Jonathan Stolk, Mark Somerville, John B. Geddes, Rob Martello

Mark Somerville

The literature consistently reports that students express some degree of discomfort when they are thrown into self-directed learning environments. In this paper, we present the preliminary results of an investigation of the causes of student discomfort in several different self-directed project-based courses. Our results suggest that student motivation and opportunities for the development of deep understanding and transferable skills are important in creating a positive self-directed learning experience. Negative experiences and student discomfort in self-directed environments may stem from problems with self-regulation, low self-perceptions of content learning, lack of personal engagement with the topic, and difficulties related to the social …


Lachesis: A Job Scheduler For The Cray T3e, Allen B. Downey Jul 2012

Lachesis: A Job Scheduler For The Cray T3e, Allen B. Downey

Allen B. Downey

This paper presents the design and implementation of Lachesis, a job scheduler for the Cray T3E. Lachesis was developed at the San Diego Supercomputer Center (SDSC) in an attempt to correct some problems with the scheduling system Cray provides with the T3E.


On The Issue Of Decoupled Decoding Of Codes Derived From Quaternion Orthogonal Designs, Tadeusz Wysocki, Beata Wysocki, Sarah Spence Adams Aug 2009

On The Issue Of Decoupled Decoding Of Codes Derived From Quaternion Orthogonal Designs, Tadeusz Wysocki, Beata Wysocki, Sarah Spence Adams

Sarah Spence Adams

Quaternion orthogonal designs (QODs) have been previously introduced as a basis for orthogonal space-time polarization block codes (OSTPBCs). This note will serve to correct statements concerning the optimality of a decoupled maximum-likelihood (ML) decoding algorithm. It will be shown that when compared to coupled decoding, the decoupled decoding is only optimal in certain cases. This raises several open problems concerning the decoding of OSTPBCs.
