Comparison of School Characteristics Among RAMP and Non-RAMP Schools

Non-Local Feedback Ramp Metering Controller Design

This paper treats the problem of controlling large freeway systems through ramp metering to enhance their efficiency. Following a rigorous discretization methodology, an extension of the CTM model to inhomogeneous freeways with on and off ramps is proposed. Based on passivity theory and the piecewise affine formulation of this model, an LMI formulation is developed to design non-local feedback ...

Meniscal Ramp Lesions

Meniscal ramp lesions are more frequently associated with anterior cruciate ligament (ACL) injuries than previously recognized. Some authors suggest that this entity results from disruption of the meniscotibial ligaments of the posterior horn of the medial meniscus, whereas others support the idea that it is created by a tear of the peripheral attachment of the posterior horn of the medial meni...

Multiple ramp schemes

A (t; k; n; S) ramp scheme is a protocol to distribute a secret s chosen in S among a set P of n participants in such a way that: 1) sets of participants of cardinality greater than or equal to k can reconstruct the secret s; 2) sets of participants of cardinality less than or equal to t have no information on s, whereas 3) sets of participants of cardinality greater than t and less than k migh...

Transistor-Based Ramp Generator

For the analog-to-digital conversion lab, we need a resetable ramp generator. Here, we explore building a ramp generator from a current source. We show two implementations that both use a PNP current source.
