Carbon dioxide (CO2 ) sensors that provide a visual indication were installed in classrooms during normal school operation. During 2-week periods, teachers and students were instructed to open the windows in response to the visual CO2 feedback in 1 week and open them, as they would normally do, without visual feedback, in the other week. In the heating season, two pairs of classrooms were monit...

We present a methodology to validate land surface temperature (LST) retrieved from Advanced AlongTrack Scanning Radiometer (AATSR) data in heterogeneous areas. To this end, a set of algorithms based on Split-Window (SW) and Dual-Angle (DA) techniques has been proposed and evaluated with in situ measurements of LST obtained from field campaigns made in heterogeneous areas. These campaigns were c...

In conventional multicast communication, the source carries a single conversation with all destination nodes. If a node on the path to any destination becomes congested, the throughput to all destinations is reduced, thus treating some destination nodes unfairly. We consider a window-controlled multipoint connection and study the use of destination set grouping, where the destination set can be...

Junior Barrera Departamento de Ciência da Computação Instituto de Matemática e Estatı́stica— Universidade de São Paulo Rua do Matão, 1010 05508-900 São Paulo, Brazil E-mail: [email protected] Abstract. Iterating (composing) a sequence of window operators results in an operator defined over the window determined by the dilation of the component windows. Although a statistically designed iterative ope...

Temperature-modulated differential scanning calorimetry ~MDSC! measurements on SixSe12x glasses show glass transitions to be thermally reversing in character in the composition window 0.20,x,0.27. Raman scattering shows a trimodal distribution of vibrational modes, identified with corner-sharing ~CS!, edge-sharing ~ES!, and Se-chain modes ~CM!. In the floppy region, 0,x,0.19, these modes are sy...

A Markov chain model for evaluating the performance of a multistage ATM switching fabric using split shared buuered switch elements (SE) is proposed. By comparing the results obtained from the proposed model and simulations, it is shown that the model is accurate in the presence of uniform and non-uniform traac in the switch. To eliminate the innuence of head of line blocking, a non-FIFO queuei...

Satellite land surface temperature (LST) derivation is usually performed at infrared spectrum using multi-channel technique. Because of coupled effects in LST problem, spectral land surface emissivity information is required explicitly or implicitly in such technique, which itself is difficult to be determined accurately. Gillespie et al. [1] presented a numerical method for separating LST and ...

This is a short note to explain how to efficiently minimize the nonlocal Total Variation (NLTV) energy. The method is based on the Split-Bregman (SB), introduced by Goldstein-Osher in [8], and extended to a nonlocal/graph version by Zhang-Burger-Bresson-Osher in [13]. For the 256 × 256 Barbara picture, the computation of weights takes around 1 second for a patch size 5 × 5 and a search window 1...

In recent years, the need for continuous processing and analysis of data streams has increased rapidly. To achieve high throughput-rates, stream-applications make use of operatorparallelization, batching-strategies and distribution. Another possibility is to utilize co-processors capabilities per operator. Further, the database community noticed, that a columnoriented architecture is essential ...

Land surface temperature (LST) is one of the most important variables measured by satellite remote sensing. Public domain data are available from the newly operational Landsat-8 Thermal Infrared Sensor (TIRS). This paper presents an adjustment of the split window algorithm (SWA) for TIRS that uses atmospheric transmittance and land surface emissivity (LSE) as inputs. Various alternatives for es...
