Local forecasting could identify future low-voltage bottlenecks

Monitoring Novice Programmer Affect and Behaviors to Identify Learning Bottlenecks

We analyze student affect data in order to locate bottlenecks in an introductory programming course. By tracking students’ affective states and behaviors over five laboratory sessions distributed over nine weeks, we find that students exhibit a significantly greater amount of confusion when expected to implement object-oriented constructs such as constructors and object interaction. When asked ...

Power Quality in Future Low Voltage Electricity Networks

Using Archived Data to Systematically Identify and Prioritize Freeway Bottlenecks

Bottlenecks are critical components of freeway systems and are of increasing importance as congestion worsens in major urban areas. In the U.S., the Federal Highway Administration has launched a new initiative aimed at identifying key bottlenecks in each state. In Oregon, a freeway data archive has been established that stores vehicular count, occupancy, and speed data from over 600 locations a...

Review and future prospects of low-voltage RAM circuits

This paper describes low-voltage random-access memory (RAM) cells and peripheral circuits for standalone and embedded RAMs, focusing on stable operation and reduced subthreshold current in standby and active modes. First, technology trends in low-voltage dynamic RAMs (DRAMs) and static RAMs (SRAMs) are reviewed and the challenges of lowvoltage RAMs in terms of cell signal charge are clarified, ...

Learning to Identify Global Bottlenecks in Constraint Satisfaction Search

Using information from failures to guide subsequent search is an important technique for solving combinatorial problems in domains such as boolean satisfiability (SAT) and constraint satisfaction problems (CSPs). The information learnt can take various forms such as fine-grained information in the form of no-goods and explanations in CSPs and clause learning in SAT, or coarse-grained informatio...
