In this study, the effects of graphene oxide (GO) nanosheets on physicochemical properties and performances cellulose acetate butyrate (CAB) membranes were investigated. Nanocomposite fabricated using CAB a small amount GO in range 0 to 0.07 wt.%, conventional phase-inversion method. Membranes characterized by different methods their tested dead-end filtration system. Compared with pristine mem...

The Urban Research Center (URC) in Harlem, New York City, is a collaboration of community members, service providers, and academics. A Community Advisory Board (CAB) meets regularly to formulate priorities for action and to direct research. A conceptual model of social determinants of health relevant to the Harlem community was developed. Early meetings of the CAB identified substance use as a ...

Predicting the future location of users in wireless networks has numerous important applications, and could in turn help service providers to improve the quality of service perceived by their clients (e.g. by applying smart data prefetching and resource allocation strategies). Many location predictors have been devised over the last decade. The predictors proposed so far estimate the next locat...

Design of heavy earthmoving equipment is based primarily on feedback from drivers. Most design studies on ingress and egress focus on the motion itself and rely heavily on experimental data. This process requires physical construction of expensive (in terms of time and money) mockups before any feedback can be obtained. Postfeedback design changes and the analysis of those changes are again exp...

Does the level of sunlight affect the tipping percentage in taxicab rides in New York City? We examined this question using data on 13.82 million cab rides from January to October in 2009 in New York City combined with data on hourly levels of solar radiation. We found a small but statistically significant positive relationship between sunlight and tipping, with an estimated tipping increase of...

We investigate a novel cluster-of-bandit algorithm CAB for collaborative recommendation tasks that implements the underlying feedback sharing mechanism by estimating the neighborhood of users in a context-dependent manner. CAB makes sharp departures from the state of the art by incorporating collaborative effects into inference as well as learning processes in a manner that seamlessly interleav...

— In this paper, we show that the reduction of divisors in the Jacobian of a curve C can be performed by considering the intersections of a suitable projective model of C with quadrics in projective space. We apply this idea to certain projective model of elliptic and hyperelliptic curves on one hand, and to the canonical model of Cab curves on the other hand, and we find well known algorithms....
