Two approaches for estimation of remotely sensed land surface temperature, Ts, based on MSG-SEVIRI data have been tested in a semi-arid environment in West Africa. A local algorithm, based on in situ measured Ts and a regional algorithm, based on MODIS LST products. They are both based on the split-window technique and show encouraging results, however applications are limited to the region for...

Two formulations of the stochastic model predictive control (SMPC) problem for the control of large-scale drinking water networks are presented in this chapter. The first approach, named chance-constrained MPC, makes use of the assumption that the uncertain future water demands follows some known continuous probability distribution while at the same time certain risk (probability) for the state...

Electronic Health Records (EHRs) consist of sparse, noisy, incomplete, heterogeneous and unevenly sampled clinical data of patients. They include physiological signals, lab test results, procedural events, clinical notes. Such data can be treated as a temporal stream of events of varied types occurring at irregularly spaced time points. We focus on modeling the temporal dependencies that arise ...

Air temperature (Ta) is a key input in a wide range of agroclimatic applications. Moderate Resolution Imaging Spectroradiometer (MODIS) Ts (Land Surface Temperature (LST)) products are widely used to estimate daily Ta. However, only daytime LST (Ts-day) or nighttime LST (Ts-night) data have been used to estimate Tmax/Tmin (daily maximum or minimum air temperature), respectively. The relationshi...

Access to data services through wireless means gains is becoming commonplace daily. Wireless LANs are deployed in both private (e.g., corporate or home) and in public “hot-spot” (e.g., hotels and airports) settings. Accessing data services via (for profit) public wireless LAN (PWLAN) installations is typically based on user subscription and pre-configured services profiles pertaining primarily ...

The popularity of the Web has created a great marketplace for businesses to sell and showcase their products increasing the need for secure Web services such as SSL, TLS or SET. We propose a pseudorandom bit generator that can be used to create a stream cipher directly applicable to these secure systems; it is based on the powers of a block upper triangular matrix achieving great statistical re...

Since 2002, the GRACE satellite mission provides estimates of the Earth’s dynamic gravity field with unprecedented accuracy. Differences between monthly gravity fields contain a clear hydrological signal due to continental water storage changes. In order to evaluate GRACE results, the state-of-the-art WaterGAP Global Hydrological Model (WGHM) is applied to calculate terrestrial water storage ch...

The exponential growth of the Internet combined with the increasing popularity of streaming audio and video are pushing Internet bandwidth constraints to their limits. Methods of managing and more eeciently utilizing existing bandwidth are becoming increasingly vital. Using IP multicast to deliver content, especially streaming audio and video, can provide enormous bandwidth savings. A decade of...
