Optimized inequality join method

The optimized inequality join method is a method for joining relational tables on input inequality conditions. The optimized inequality join method is a relatively fast inequality join method using permutation arrays to store positional information for sorted attributed values. Additionally, space efficient bit arrays are used to enable optimization, such... Qatar Foundation

Hybrid organic-inorganic perovskite-based solar cell with copper oxide as a hole transport material

The hybrid organic-inorganic perovskite-based solar cell with copper oxide as a hole transport material includes a transparent conducting film layer (12) sandwiched between a glass substrate (11) and a titanium dioxide layer (14). The transparent conducting film layer (12) can be fluorine-doped tin oxide. A lead methylammonium tri-iodide perovskite layer... Qatar Foundation

Modulation and control methods for quasi-z-source cascade multilevel inverters

The modulation methods for quasi-Z-source cascade multilevel inverters relate to control and signal modulation of quasi-Z-source cascade multilevel inverters, such as those used with photovoltaic power systems. The modulation methods for quasi-Z-source cascade multilevel inverters include a modular multilevel space vector modulation method for a photovoltaic quasi-Z-source cascade multilevel inverter... Qatar Foundation

Hybrid desalination system

The hybrid desalination system is a desalination system for seawater which uses both filtering and treatment from a reverse osmosis filter system as well as evaporative distillation for the production of potable water. The hybrid desalination system includes a recovery system, which may be a reverse osmosis system, a forward... Qatar Foundation

Hybrid partial power processing system

The hybrid partial power processing system includes differential power processing converters DPPs having low power ratings, which are used to exchange differential power between two adjacent PV modules, or between PV modules and a line capacitor (Clin) connected in series within the same string. The exchange of differential power by... Qatar Foundation

Method of converting high voltage ac lines into bipolar high voltage dc systems

The method of converting high voltage AC lines into bipolar high voltage DC systems makes use of the three transmission lines (referred to as the positive pole, the negative pole, and the modulating pole) in an existing high voltage AC system as transmission lines in a bipolar high voltage DC... Qatar Foundation

Geo-security method and system

The geo-security method and system uses spatio-temporal radio channel information during authentication to grant permission to access, use and/or operate the intended device. The geo-security method and system uses a wideband radio channel impulse response (or transfer function of radio channel) from antenna of RF source to antenna of a... Qatar Foundation

Method and simple angle of arrival estimation

The method and apparatus for angle of arrival estimation are used for estimating the angle of arrival of a received signal by a switched beam antenna array and a single receiver. The switched beam antenna array first collects an omnidirectional signal to be used as a reference signal. A main... Qatar Foundation
