Abstract-Cyber-physical systems (CPSs) are physical and engineered systems whose operations are monitored, coordinated, controlled, and integrated by a computing, control, and communication core. We propose Cyberphysical-System-on-Chip (CPSoC), a new class of sensor and actuator-rich multiprocessor systemson-chip (MPSoCs), that augment MPSoCs with additional onchip and cross-layer sensing and actuation capabilities to enable self-awareness within the observe-decide-act (ODA) paradigm. Unlike traditional MPSoC designs, CPSoC differs primarily on the co-design of computing-communication-control (C3) systems that interacts with the physical environment in real-time in order to adapt system behavior so as to dynamically react to environmental changes while achieving overall design goals. We illustrate CPSoC's potential through a virtual sensor network that accurately estimates run-time power for variability affected subsystems using noisy thermal sensors in improving system goals and Quality-of-Service (QoS).

The kinetics of the oxidation of a number of aliphatic and aromatic secondary alcohols with Nbromo succinimide has been investigated. Electron-withdrawing substituents retard the reaction considerably and electron-releasing substituents increase the rate of oxidation. The Taft p* value is -2.56. Cis-and tram-4-t-butyl cyclohexanols arc oxidized at nearly the same ratcs. There is also a good correlation between the rates of the NBS oxidations and Br, oxidations of these alcohols. The results are interpreted in ternis of a cyclic mechanism involving a rate-determining abstraction of the alpha hydrogen as a hydride anion. For personal use only.

The preferred conformation of the side chain ClI-CHa in 7-lactones on the eudesmane skeleton is discussed in the light of thermodynamic studies recently conducted on some of these compounds. Reasons are advanced to justify the results, which are contrary to earlier assumptions. Two simple methods, one depending on solvent shifts and the other on coupling constants, are presented to find directly the stereochemistry of this methyl group in any y-lactone.
