“…[6e,f] Following the initial disclosure by Noyori et al,[6a] it was found that the closely related Ir complex 5 was also active in the asymmetric reduction of -hydroxy acetophenone derivatives. [6d] Complexes 1 and 5, and the related Rh complex 6 have found application in the asymmetric hydrogenation of cyclic and acyclic imines [8] and in the asymmetric reduction of quinoline derivatives. [9] Recently, we reported the synthesis and applications to asymmetric transfer hydrogenation of a series of complexes which contain a linking group ('tether') between the TsDPEN unit and the arene ring on the ruthenium atom.…”

An improved method for the synthesis of tethered ruthenium(II) complexes of monosulfonylated diamines is described, together with their application to hydrogenation of ketones and aldehydes. The complexes were applied directly, in their chloride form, to asymmetric ketone hydrogenation, to give products in excess of 99% ee in the best cases, using 30 bar of hydrogen at 60 °C , and to the selective reduction of aldehydes over other functional groups.

Abstract-Mining frequent pattern from stream data is a challenging task. Finding frequent pattern from data streams have been found to be useful in many application such as stock market prediction, sensor data analysis, network traffic analysis, e-business and telecommunication data analysis. Frequent Pattern Stream tree [1] is used for maintaining frequent pattern over a period of time using modified FP tree algorithm. This approach maintains tilted time window at each node which consumes larger space. Compact Pattern Stream Tree [2] assumes that only current patterns are of importance and uses sliding window protocol for maintaining it. This approach does not give importance to past frequent patterns.

“…A variety of significant studies have been made concerning dispatch optimization with multiple goals for MGs [15][16][17][18]. Some main objectives are shown in [19], including maximizing the power availability of customer, minimizing operation cost and decreasing greenhouse gas emissions. All these objectives should be achieved under constraints, such as system power balance, power transmission constraints and the output limitation of devices.…”

An active power dispatch method for a microgrid (MG) with multi-type loads, renewable energy sources (RESs) and distributed energy storage devices (DESDs) is the focus of this paper. The MG operates in a grid-connected model, and distributed power sources contribute to the service for load demands. The outputs of multiple DESDs are controlled to optimize the active power dispatch. Our goal with optimization is to reduce the economic cost under time-of-use (TOU) price, and to adjust the excessively high or low load rate of distributed transformers (DTs) caused by the peak-valley demand and load uncertainties. To simulate a practical environment, the stochastic characteristics of multi-type loads are formulated. The transition matrix of system state is provided. Then, a finite-horizon Markov decision process (FHMDP) model is established to describe the dispatch optimization problem. A learning-based technique is adopted to search the optimal joint control policy of multiple DESDs. Finally, simulation experiments are performed to validate the effectiveness of the proposed method, and the fuzzification analysis of the method is presented. Keywords
