This paper describes the results of an ITiCSE working group convened in 2013 to review and revisit the influential ITiCSE 2001 McCracken working group that reported  on novice programmers' ability to solve a specified programming problem. Like that study, the one described here asked students to implement a simple program. Unlike the original study,… (More)
We describe a radix-2 FFT implementation on the Connection Machine. The FFT implementation pipelines successive FFT stages to make full use of the communication capability of the network interconnecting processors, when there are multiple elements assigned to each processor. Of particular interest in distributed memory architectures such as the Connection… (More)
Moving regions are a form of spatiotemporal data in which a region changes in shape and/or position over time. In many fields, moving regions representing real-world phenomena are collected using sensors that take temporally encoded snapshots of regions. We provide a novel algorithm that creates a moving region between any two complex regions. The proposed… (More)
Contextualization of problems is widely studied in mathematics education. In computer science it is taken for granted that authentic, contextualized programming assignments will increase student interest and therefore enhance performance in programming assignments. This paper examines whether contextualization is, in fact, beneficial for students. We… (More)
A temporal coverage operation computes the duration that a moving object covers a spatial area. We extend this notion into temporal coverage aggregates, in which the spatial area covered for a maximum or minimum amount of time by a moving region, or set of moving regions, is discovered.
The purpose of this document is to describe coexistence between version 3 of the Internet-standard Network Management Framework, (SNMPv3), version 2 of the Internet-standard Network Management Framework (SNMPv2), and the original Internet-standard Network Management Framework (SNMPv1). This document also describes how to convert MIB modules from SMIv1… (More)
