Co(II) and Cu(II) promoted base hydrolysis of 2-cyano, 1, lO-phenanthroline was studied. At 298.2°K, Cu(II) reaction is more efficient (by a factor of 20) than either Co(ll) and its analogues Ni(II) in promoting base hydrolysis.

cobalt (ii) chloride was used as a precursor to prepare co 3 o 4 nanotubes in reverse micelles. tween 80 was added as surfactant. the products were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy. the diameter of co 3 o 4 nanotubes was about 58 nm and the average length of them was around 261 nm. the study provides a simple and e...

This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...

{gaojun, dqyang, tjwang }@ pku.edu.cn Abstract XML query rewriting in the distributed computing environment receives high attention recently. Different from existing work, we focus on the query rewriting in the cases that there are multiple views at the client side. We design two data structures to manage the multiple XML views. MPTree is constructed from the main path of the XML views to gener...

Tremendous advancement in technology most of the people are using their cell phone to access internet anywhere and everywhere. So, they need to concentrate on battery power also because of the limited battery power. In this paper, we propose an energy and latency efficient XML dissemination scheme for the wireless devices. We define a new unit structure called G-node for sending XML data in the...

A path integral formalism has been proposed recently for non-equilibrium statistical physics applications (see [2]). In this contribution we outline an efficient method for its numerical evaluation. The method used is based on the multiscale MCMC method of Ceperley and co-workers in quantum applications. A significant new feature of the method proposed is that the time endpoint is not fixed and...

We present a measurement study of TCPW BBE (Bandwidth and Buffer Estimations) [5] and associated path characteristics estimation techniques over large pipes. Our study addresses the accuracy of our inline estimation methods used in TCPW BBE. Buffer size, capacity, and achieved rate estimation are used in TCPW BBE. We shed some light on the accuracy and speed of these estimates, and on the effic...

The physical implementation of most relational databases follows their logical description, where each relation is stored in its own file or collection of files on disk. Such an implementation is good for queries that filter or aggregate large portions of a single table, and provides reasonable performance for queries that join many records from one table to another. It is much less ideal, howe...
