Abstract When a communicator faces word-formulation problem, they may use placeholder (PH) such as whatchamacallit to avoid producing target expression or delay it. A PH is dummy element used fill in the syntactic slot of item that unable unwilling produce (e.g. due memory lapse). Previous studies have generally been concerned with grammatically stable PHs , you-know-what ), ‘grammatically stab...

Wireless Local Area Networks (WLAN)s are today common for access to Internet; well-known and used is IEEE 802.11 standardized technology. Some drawbacks of the standardized distributed medium access scheme, Distributed Coordination Function (DCF) has resulted in considerations made to extend the DCF from single-hop communications to multi-hop. Multihopping has the potential to reduce energy con...

Discrete-Time H2 Guaranteed Cost Control by Richard Anthony Conway Doctor of Philosophy in Engineering – Mechanical Engineering University of California, Berkeley Professor Roberto Horowitz, Chair In this dissertation, we first use the techniques of guaranteed cost control [28] to derive an upper bound on the worst-case H2 performance of a discrete-time LTI system with causal unstructured norm-...
