On Perfect Switching Classes
We study a graph transformation (defined by Seidel) called switching which, given a graph G = ( V,E) and a subset W C Jf of its vertices, builds a new graph by exchanging the cocycle linking W to V\ W with its complement. Switching is an equivalence relation and the associated equivalence classes are called switching classes. A switching class is perfect if it contains only perfect graphs. We s...
متن کاملMaintaining Telephone Switching Software Requirements ∗
We discuss how telephony software requirements should be structured to reduce maintenance costs. “Feature interaction” problems have become a serious obstacle to add more features to telephone switches. We show why existing public switched telephone networks are hard to modify. We then argue that a more modular, layered requirements architecture can help. Finally we survey approaches for such a...
متن کاملState-Switching Return Predictability
Return predictability may be hidden from view if the same information has different meanings at different times, especially if information is good news in one state but bad news in another. We illustrate, using price changes in industrial metals, how conclusions on stock market return predictability vary with the number of expansions and contractions in our sample. We also show how state-switch...
متن کاملSwitching State-Space Models
We introduce a statistical model for times series data with nonlinear dynamics which iteratively segments the data into regimes with approximately linear dynamics and learns the parameters of each of those regimes. This model combines and generalizes two of the most widely used stochastic time series models|the hidden Markov model and the linear dynamical system|and is related to models that ar...
متن کاملSleep State Switching
We take for granted the ability to fall asleep or to snap out of sleep into wakefulness, but these changes in behavioral state require specific switching mechanisms in the brain that allow well-defined state transitions. In this review, we examine the basic circuitry underlying the regulation of sleep and wakefulness and discuss a theoretical framework wherein the interactions between reciproca...
