This document provides an overview of connection admission control (CAC) techniques for orthogonal frequency-division multiple access (OFDMA)-based WiMAX networks. It analyzes the performance of two CAC policies - threshold-based and queue-aware - through developing queueing models and discrete-time Markov chains. The analysis captures key quality of service measures like blocking probability, throughput, and delay under different traffic loads. Numerical results demonstrate the queue-aware policy provides better performance than the threshold-based policy.

Lightning talk (5') on the project RRI Tools and the RRI Toolkit, to be publicly launched in February 2016, at the European Citizen Science Assembly 2015 in Barcelona. The talk emphasizes the commonalities between the RRI concept and citizen science.
Neighbours
This document provides conversation starters for talking to neighbors, including commenting on the weather, congratulating a neighbor whose wife recently had a baby, expressing sympathy if the police visited their house or their husband is sick, asking about holiday plans, or making weekend plans to go out.
Steroids and the environment
Steroids enter the natural environment through wastewater from steroid injections washed down drains, animal waste containing steroid remnants applied to agricultural land, and wastewater containing very low steroid concentrations up to 360ng/L. The document discusses how sewage treatment plants and cleaning up animal waste could help address this issue and proposes waste combustion for renewable energy as alternatives.
Clima continental
El documento describe el clima continental, localizado principalmente en Europa Central y Oriental, así como en zonas templadas de Asia y América del Norte. Presenta veranos cálidos con tormentas y inviernos fríos con nieve. A pesar de las escasas precipitaciones, los ríos tienen un caudal considerable debido a que recogen agua de amplias zonas llanas. La vegetación varía desde bosques de coníferas en el norte hasta agricultura y ganadería en las zonas más secas.
Clima mediterráneo
El clima mediterráneo se caracteriza por veranos secos y calurosos y inviernos suaves. Se localiza en las costas del Mediterráneo, California, Chile, Sudáfrica y el sur de Australia. Los veranos están afectados por masas de aire caliente subtropical, mientras que los inviernos son más suaves debido a la influencia moderadora del mar. La vegetación incluye bosques mediterráneos con árboles perennes como pinos y encinas, y abunda la fauna como conejos, ratones y serpientes

Textual analysis my own 1
The document analyzes two music magazines, NME and Kerrang, to inform the creation of a new music magazine. NME's target audience is ages 15-34, mainly upper and lower middle class. It attracts more male readers. Kerrang targets lower class ages 15-34 due to its lower price. It attracts more male readers who are interested in rock music. The author concludes NME is most similar to their intended audience and genre of music (hip hop and R&B). The publisher of NME, IPC Media, would be a good publisher choice since they produce various magazines and two existing music magazines.

Les Femmes CSP+ et la Beauté
Les femmes CSP+ sont sûrement encore plus que les autres concernées par la beauté. D’abord parce qu’avant d’être CSP+ elles sont femmes et ainsi elles aiment s’accorder du temps pour soi et établir de petits rituels. La notion de CSP+ s’ajoute à celle du plaisir avec une perception de la beauté comme une obligation sociale, de représentation. La beauté est donc très importante pour ces femmes CSP+ à double titre. La crise n’est pas passée par là et elles ne sont pas prêtes à faire des sacrifices dans leurs habitudes beauté : elles continuent et continueront de dépenser dans ce domaine qu’elles continuent d’explorer avec plaisir comme par exemple le bio…
TU1.L10.2 - ESTIMATION OF ICE THICKNESS OF TUNDRA LAKES USING ERS–ENVISAT CR...
This document presents a method for estimating ice thickness in tundra lakes using cross-interferometry of ERS and ENVISAT SAR data. The method is tested on two study sites in Siberia and Canada, showing coherence over frozen lakes allows sensitivity to ice thickness changes of around 3 meters. Comparisons to in-situ measurements confirm the potential to map ice thickness and lake floor topography where the ice is frozen to the bottom. Limitations exist for other ice types where the dominant scattering is not from the ice/water or ice/ground interfaces.

This document summarizes research using RADARSAT-2 data to detect ships and oil slicks. For ship detection, target-to-clutter ratio (TCR) was found to be higher for horizontal-horizontal (HH) polarization at large incidence angles and horizontal-vertical (HV) polarization at small incidence angles. TCR also increased as ship length and orientation perpendicular to radar look increased. For oil slick detection, polarimetric entropy increased with incidence angle, so oil type discrimination requires validation. Target decomposition showed scattering dominated by the first two eigenvalues, suggesting the cross-polarization term can be neglected. This research aims to better understand target decomposition for oil slick discrimination.
McNairn soil moisture IGARSS 2011 v2.ppt
The document summarizes research on using RADARSAT-2 satellite data to monitor soil moisture for agricultural risk reduction in Canada. It finds that a calibrated Integral Equation Model can estimate regional soil moisture with an average error of 3.23% and detect changes in soil moisture over time. However, site-specific estimates have higher errors of 7.71% due to spatial variability not captured. Further analysis is needed to reduce errors and better quantify relative changes in soil moisture.

1. The document analyzes changes in land surface albedo over the Qinghai-Tibetan Plateau from 2000 to 2009 using satellite data on albedo, snow cover, and vegetation indices.
2. Results show albedo is strongly correlated with snow cover, with higher albedo corresponding to more frequent snow cover. Summer albedo is correlated with vegetation indices.
3. Interannual trends found albedo changes were driven by changes in snow cover and vegetation in different regions of the plateau, with snow cover dominating in some areas and vegetation in others.
OBSERVING OCEAN SURFACE WIND AND STRESS BY SCATTEROMETER CONSTELLATION
The document discusses scatterometry and its unique ability to measure ocean wind and stress. Scatterometers send microwave pulses to measure ocean surface roughness caused by small waves in equilibrium with wind stress. This allows measurement of wind and stress vectors, which is unique to scatterometry. It also discusses using equivalent neutral winds from scatterometry to study various ocean-atmosphere phenomena like hurricanes, monsoons, and air-sea interactions.

The document discusses advances in radar remote sensing techniques for observing Earth's atmosphere. It describes the structure of the atmosphere and the basic principles of radar techniques. Recent radar systems like the MU radar in Japan can measure atmospheric parameters like wind velocity with high temporal and altitude resolution. Radars have been used to study dynamics in the upper, middle, and lower atmosphere. Atmospheric gravity waves observed by radar modulate wind profiles and transport momentum, affecting atmospheric structure. Range imaging techniques allow reconstruction of time series and Doppler spectra at any height within the radar observation volume.

The document summarizes the performance of a high-resolution wide-swath SAR system operating in stripmap quad-polarized mode and ultra-wide ScanSAR mode. In stripmap quad-pol mode, the system achieves a spatial resolution of 1m x 1m across 12 subswaths covering a 20-50km swath with a NESZ below -19.5dB and RASR below -19dB and -27dB for cross and co-polarization, respectively. In ultra-wide ScanSAR mode, the system images a 375km swath in a single pass with a spatial resolution of 1m x 9m, NESZ below -22.6dB, RASR

This document summarizes a new approach for classifying remote sensing signatures extracted from multispectral imagery. It combines spectral signatures to perform accurate classification. Simulation results are provided to verify the efficiency of the proposed weighted pixel statistics approach, which uses information from multiple spectral bands. It is shown to provide more accurate and less smoothed identification of classes compared to traditional weighted order statistics methods.

This document summarizes a study that used feature selection and classification methods to identify tree species in high-resolution satellite images. The researchers tested 35 features on over 1000 ground reference samples to rank their effectiveness for classification. They found that 6 spectral features performed best when used in a 5-nearest neighbor classifier, achieving over 80% accuracy for tree species identification. While species proportions were estimated accurately, stem numbers per species showed only moderate correlation with field data. Future work could explore more advanced classifiers, cross-validation, and improving stem number estimation.
