nano-cufe2o4 catalysts with different cu/fe molar ratios (cunfemo(n+1.5m)) were prepared by hydrothermal method. the thermal decomposition performance of cunfemo(n+1.5m) on cuso4 were determined with tg-dsc method to evaluate its catalytic activity and the roasted product was characterized by xrd. the results showed that cunfemo(n+1.5m) had superior catalytic properties and efficiency to cuso4 ...

It is estimated that more than 80% of data that human beings have collected so far are geospatial data. In order for the geospatial data to be useful, information has to be extracted from the data and converted to knowledge. However, currently it is very difficult for general users to obtain geospatial data and turn them into useful information and knowledge. In order for geospatial information...

This study examines two issues which have challenged prior experimental or survey research: (1) whether the time-varying effects of service recovery on customer satisfaction may follow a long decay or short decay and (2) why and what service recovery efforts have a higher and quicker buildup, with respect to the significance and timing of recovering customer satisfaction losses due to service f...

The potential for long-term facility loss has important implications for the reliability of service/supply networks. In order to design a coverage-type service network that is robust to the worst instances of facility loss, we develop a location-interdiction covering model that maximizes a combination of 1) initial coverage given p facilities and 2) the minimum coverage level following the loss...

Video-on-Demand (VOD) servers are becoming feasible. These servers have voluminous data to store and manage. If only disk-based secondary storage systems are used to store and manage this huge amount of data the system cost would be extensively high. A tape-based tertiary storage system seems to be a reasonable solution to lowering the cost of storage and management of this continuous data. How...

simultaneous thermal analysis (sta) method has been applied to study decomposition reactions of ap under a flowing nitrogen atmosphere and static air. results obtained indicate that a phase transformation occurs prior to the decomposition reaction. decomposition takes place exothermally in two stages, first stage of decomposition could be suppressed by the controlled heating programme. addition...

in the 1960's noboru iwahori and hideya matsumoto, eiichi abe and kazuo suzuki, and michael stein discovered that chevalley groups $g=g(phi,r)$ over a semilocal ring admit remarkable gauss decomposition $g=tuu^-u$, where $t=t(phi,r)$ is a split maximal torus, whereas $u=u(phi,r)$ and $u^-=u^-(phi,r)$ are unipotent radicals of two opposite borel subgroups $b=b(phi,r)$ and $b^-=b^-(phi,r)$ contai...

Virtual enterprise is a temporary network of independent companies or enterprises that can quickly bring together to fulfill a value-added task. With the development of Web service technologies, the enterprise business systems can be encapsulated as Web services. Establishing a virtual enterprise is actually a process of Web service composition. As more and moreWeb services with the same functi...
