Many distributed protocols arising in applications in on-line load balancing and dynamic resource allocation can be modeled by dynamic allocation processes related to the \balls into bin" problems. Traditionally the main focus of the research on dynamic allocation processes is on verifying whether a given process is stable, and if so, on analyzing its behavior in the limit (i.e., after suucient...

W ith the advent of near-equilibrium growth techniques, it is now possible to synthesize virtually any type of crystalline nanostructure. Researchers can exert a fine control over size, shape and surface chemistry to tailor the properties of their nanomaterial to specific applications relevant to energy conversion, sensing, electronics and photonics. Once in a device, these nanostructures are f...

results seventy-five patients completed the study. compared to saline, patients who received 1 and 5 mg/kg of aminophylline demonstrated decreased extubation times (mean ± sd) (12.26 ± 7.33 vs. 11.15 ± 8.62 and 10.4 ± 4.78 min, respectively, p = 0.001) with higher bis values (p = 0.001). however, the recovery and discharge times from the pacu were no different between the aminophylline and sali...

We describe a multi-faceted effort to demonstrate the practical implementation of stochastic unit commitment at RTO scale. The inputs for the scheduling engine consist of multiple hourly trajectories of load and variable generation availability together with probabilities that accurately describe their likelihood of occurrence given information available on the day ahead. Preliminary computatio...

Background & objective: A cross-sectional study was conducted to determine the prevalence of Plasmodium infections among migrant workers in Thailand. Methods: A total of 241 migrants at Kanchanaburi, Pathumthani and Nakornpathom provinces of Thailand were recruited in our surveillance. Blood samples were examined for human malaria parasites by using microscopy and semi-nested multiplex PCR (SnM...

ABSTRACT: Aqueous enzymatic extraction of oil from pistacia khinjuk was performed using cellulase. The central composite design was used to optimize the parameters that are significant to the process. The influence of three regressors on the percentage of oil recovery from seed was evaluated using second-order polynomial multiple regression model. Analysis of variance showed a high coefficient ...

In this paper we describe the use of a steerable camera and active vision system in the real-time recovery of trajectories of objects moving on a planar surface in the scene. The system first selfcalibrates the transformation from camera platform joint angles to scene plane coordinates by active observation of static scene geometry which has been stored as a model. The transformation is encoded...

This paper discusses a 2(1/2)-D tracking method allowing real-time recovery of the three-dimensional (3-D) position and orientation of a head moving in its image plane. The described method uses a two-dimensional (2-D) elliptical head model, regionand edge-based matching algorithms, and a linear Kalman filter estimator. The resulting motion tracking system works in a realistic environment witho...

The present article looks at the problem of iterative controller tuning, where the parameters of a given controller are adapted in an iterative manner to bring a user-defined performance metric to a local minimum for some repetitive process. Specifically, we cast the controller tuning problem as a real-time optimization (RTO) problem, which allows us to exploit the available RTO theory to enfor...

The present paper looks at the implications of anticipated changes in population size and composition for the projected number of deaths from natural disasters Building on empirical evidence from cross-country time series of factors associated with natural disaster fatalities since 1970 in 174 countries, the paper first highlights the major role of education in enabling people to cope with weat...
