Abstract: A readily erectable installation for recycling organic waste into biogas and liquid fertilizer, on an industrial scale, implementing essentially anaerobic digestion processes, is described; the readily erectable installation includes: a cylindrically shaped assemblable enclosure and a pliant collapsible anaerobic digester, suspendable from the enclosure; a compact kit-of-parts for erecting the installation and respective method using the readily erectable installation for recycling organic waste into biogas and liquid fertilizer are described.

Abstract: A method for extracting the most representative segments of a musical composition, represented by an audio signal, according to which the audio signal is preprocessed by a set of preprocessors, each if which is adapted to identify a rhythmic pattern. The output of the preprocessors that provided the most periodic or rhythmical patterns in the musical composition selected and the musical composition is divided into bars with rhythmic patterns, while iteratively checking and scoring their quality and detecting a section that is a sequence of bars with score above a predetermined threshold. Checking and scoring is iteratively repeated until all sections are detected. Then similarity matrices between all bars that belong to the musical composition are constructed, based on MFCCs of the processed sound, chromograms and the rhythmic patterns. Then equivalent classes of similar sections are extracted along the musical composition.

Abstract: A system for classification, including: (a) at least one storage apparatus configured to store information pertaining to a set of ad entity performance data associated with different geographic locations; and (b) at least one processor configured to: define a classification scheme for classification of the performance data into classes based on at least the geographic location identifier in a defining process which includes assigning a score to the geographic location identifier, based on a plurality of quantities of successful occurrences of performance data, each of the quantities is a quantity of successful occurrences having a corresponding geographic location identifier; obtain a respective subset of the performance data; determine, with respect to each class of the plurality of classes, an outcome estimation; compute, for an analyzed performance data, a performance assessment.

Abstract: In a communication system with receipt acknowledgements, a method for a receiving communication node to acknowledge receipt of a message from a sending communication node, including the receiving node embedding the acknowledgement in a message which the receiving node produces for a purpose which is more than just acknowledgement of receipt of the message, and the receiving node transmitting the message. A communication node including a message receiver for receiving messages, an acknowledgement generator for producing acknowledgements to at least some of the received messages, a message generator for producing messages for transmission, in which the receiving communication node embeds at least one of the acknowledgements in a message for transmission which the message generator produces for a purpose which is other than just acknowledgement.
