Matejic, Larisa; LOG: Building 3D User Interface Widgets By Demonstration: Building 3D widgets was until now considered a costly task done only by experts: programmers or people who understood complexities of the constraint networks found in the widgets they were constructing, as well as the mathematical details surrounding the operation their widgets were to perform. This paper addresses these problems and presents LOG, an interface for 3D widget construction. LOG is an inference-based 3D widget construction toolkit that facilitates quick and intuitive prototyping of widgets. When using LOG, designing widgets requires absolutely no programming on the user's part or understanding of the constraint networks and mathematical equations involved. Instead, all specification of constraints is done by example, where the users simply presents configurations of the widget they are constructing from defining the geometry of the widget to mapping the widget to an operation.

Dvorkina, Larisa; Simulation of Network Delays: We compare performance of two types of queuing networks: First-Come-First-Served (FCFS) and Processor Sharing (PS). Both have Poisson arrivals; both have deterministic (constant time) servers. However, in the first type the service order is FCFS, and in the second it is PS. We investigate which factors affect the relationship between the average delay of packets in the FCFS and the PS networks. Knowing how to calculate the average delay in a PS network, we try to come up with a systematic way to estimate the delay of packets in the corresponding network with FCFS servers. [Text] (1.62)
