We consider the problem of scheduling operations in bufferless robotic cells that produce identical parts. Maximizing the long-term average throughput of parts is an important problem in both theory and practice. We define an appropriate state space required to analyze this problem and show that cyclic schedules which repeat a fixed sequence of robot moves indefinitely are the only ones that ne...

BACKGROUND When learning multiple tasks, blocked or random training schedules may be used. We assessed the effects of blocked and random schedules on the acquisition and retention of laparoscopic skills. METHODS Thirty-six laparoscopic novices were randomized to practice laparoscopic tasks using blocked, random, or no additional training. Participants performed immediate post-tests, followed ...

The FaCT (Fact and Concept Training) System provides a general platform for delivering practice in the form of discrete flashcard-like drills. The system optimizes practice schedules according to model-based predictions and can be used to deliver various types of assessment. The system’s features satisfy the real world goals of educators using a theory-driven approach that gives researchers con...

[Purpose] The purpose of the current study was to compare the effectiveness of motor sequential learning according to two different types of practice schedules, distributed practice schedule (two 12-hour inter-trial intervals) and massed practice schedule (two 10-minute inter-trial intervals) using a serial reaction time (SRT) task. [Subjects and Methods] Thirty healthy subjects were recruited ...

OBJECTIVE This study (a) compares the effectiveness of different types of feedback for novices who learn to land a virtual aircraft in a fixed-base flight simulator and (b) analyzes the informational variables that learners come to use after practice. BACKGROUND An extensive body of research exists concerning the informational variables that allow successful landing. In contrast, few studies ...
