Abstract: A plate heat exchanger comprises a heat exchanger plate having a quadrilateral shape with two opposite primary sides and two opposite secondary sides, and a longitudinal central axis being parallel with the primary sides. The heat exchanger plate comprises a heat exchanger area having a corrugation of ridges and valleys. Four porthole areas are located at a respective corner of the heat exchanger plate and each comprises a respective porthole extending through the heat exchanger plate. An edge area extends around and adjoins the heat exchanger area and the porthole areas. The heat exchanger area comprises a main area and a local part area extending along one of the primary sides and adjoining the edge area and one of the porthole areas. The valleys of the local part area are tapering towards the longitudinal central axis.

Abstract: A system, method, and computer program product are presented for ranking content items. The system receives from a telecommunications network information indicating that a first subscriber has consumed a first content item through the telecommunications network, and adds an indication of the content consumption to a database. The system further receives information indicating that a second subscriber has consumed a second content item through the network, and adds an indication of the content consumption to the database. The system obtains a search result identifying a set of content items. It determines a first total number of subscribers who consumed the content item and a second total number of subscribers who consumed the content item and are determined to be similar to the requesting subscriber based on network-collected information. The system calculates a rank value for the content item using the first total number and the second total number.

Abstract: Hence a method is provided for determining a quality value of a video stream, comprising the steps of: identifying lost data packets of the video stream; identifying at least two intra coded frames of the video stream; determining intra coded frames having a maintained image quality, based on estimating if a lost data packet is associated with an intra coded frame; estimating a distance between each one of the lost data packets and a next respective, subsequent intra coded frame having a maintained image quality; and generating the quality value, based on the distances. A system and a computer readable medium are also described.

Abstract: A device for carrying an object, comprising first and second shoulder straps, first and second chest straps to be fitted around the lower chest of a person, and a back portion connecting a first end of the shoulder straps with a first end of the chest straps. Second ends of the shoulder straps are connected to the chest straps, and second ends of the chest straps are detachably connectable to each other by means of a buckle.

Abstract: Identifying lost data packets and at least two intra coded frames of a video stream can be useful in determining the quality value of the video stream. The intra coded frames having maintained image quality can be determined based on estimating whether an intra coded frame is associated with a lost data packet. This allows a distance to be estimated between each one of the lost data packets and a next respective, subsequent intra coded frame having a maintained image quanta. Based on the distances, a quality value for the video stream can be generated.

Abstract: Method and arrangement for supporting quality estimation of streamed video. The method comprises obtaining an indicator of a number of discontinuities related to a segment of a video stream, and an indicator of a number of received packets related to said segment of the video stream during a predefined period of time. The method further comprises converting said obtained indicators, by use of at least one mapping function, into a set of parameters suitable for use as input parameters to a parametric video quality estimation model. The method and arrangement enables parametric quality estimation based on the basic parameters reported by legacy equipment.

Abstract: A method for use in a flow matrix, which utilizes biospecific affinity reactions to detect an analyte in the sample, and which comprises allowing the sample comprising the analyte and an analytically detectable reactant (Reactant*) to migrate through flow channels in a flow matrix to a detection zone located in the matrix, in which there is a firmly anchored biospecific affinity reactant (Capturer), and capturing the Reactant* in the detection zone in an amount related to the amount of analyte in the sample. The Reactant* has labeled particles of an analytically detectable group, and the Capturer is anchored to the matrix by immobilized particles which exhibit hydrophilic groups on their surface. A test kit comprises a flow matrix having a detection zone in which there is a firmly anchored biospecific affinity reactant (Capturer), and an analytically detectable reactant (Reactant*).
