Abstract: A method for synchronizing a clock-free computational node in a vehicle such that the clock-free computational node is able to perform an action at a pre-defined time, including generating a mapping between at least one current counter value received from the clock-free computational node and at least one current time information received from a clock unit. Moreover, the method includes determining a pre-defined counter value being associated with the pre-defined time based on the mapping. Furthermore, the method includes providing the pre-defined counter value to the clock-free computational node. Additionally, a method for performing an action at a pre-defined time using a clock-free computational node is presented. The disclosure is directed to a corresponding first computational node including the clock unit and a second computational node being clock-free and a computational system for a vehicle.

Abstract: A method in a first device for anonymously delivering data to a part that has initiated a task is provided. The first device and the part initiating a task are participants in opportunistic sensing. The method comprises creating a data sample and encrypting the data sample with a public key of the task initiating part. After communicating the protected sample to one or more intermediate devices, one of the one or more intermediate devices delivers the protected sample to the task initiating part, such that the task initiating part does not know the identity of the first device. The task initiating device only know the identity of the one of the one or more intermediate devices that delivered the protected sample to the task initiating part, wherein the intermediate devices are participants in the opportunistic sensing.

Abstract: A service provider node (101), and a method therein, for transmitting data packets relating to parts of a service to a communication device (102). The service provider node and the communication device are communicatively connected over a communications network (104) and comprised in a communications system (100). The method comprises receiving (205, 302) a signal (S1), which signal comprises an identifier of the communication device requesting a service, an identifier of the requested service, and an agreement comprising information about a previously agreed part of the service. The method comprises further agreeing (303) on an upcoming part of the service requested by the communication device, while transmitting (206, 304) data packets relating to the previously agreed part of the service to the communication device, wherein the data packets are transmitted in dependence of the received signal.

Abstract: A method and system are provided to mask out the background in dynamic PET images, to perform pre-normalization on the masked dynamic PET images, and to apply multivariate image analysis (e.g., principal component analysis PCA) on the masked pre-normalized dynamic PET images in order to improve the quality of the dynamic PET images and the PET study. A masking operation applies PCA to untreated dynamic PEET images before any pre-normalization in order to mask out the background pixels. This masking operation uses the Otsu method. A first normalization method is background noise pre-normalization where pixel values are corrected for background noise. A second normalization method is kinetic pre-normalization where the contrast within an image is improved. Multivariate analysis such as PCA may be applied on the whole volume to find the largest variance in the structure.

Abstract: A method and system are provided for improving the quality in positron emission tomography (PET) images. PET input data is masked using raw dynamic PET data (sinograms) as input for primary component analysis (PCA) that generates primary components which in turn are used to create a mask. This mask can be used to allow object pixel data to be extracted from the sinograms into masked sinograms where background pixels outside the reference object are set to zero. A volume-wise approach to PCA uses masked sinograms as input data. Pixel-wise noise pre-normalization may then be performed generating pre-normalized sinograms from the masked PET input data. PCA is then performed on the pre-normalized sinograms resulting in PCA sinograms recreated into PCA-modified sinograms by adding background pixel values of zero. These PCA-modified sinograms may optionally be scaled and may then be reconstructed into dynamic PET images with improved image quality.

Abstract: A method and system are provided for improving the quality in positron emission tomography (PET) images. Image quality may be improved by pre-normalizing dynamic PET images and then applying a multivariate analysis tool on the images to generate improved quality dynamic PET images. The dynamic PET images are the images reconstructed from the raw dynamic PET data in the image domain of the PET study. A first normalization method is a data treatment (also referred to as noise pre-normalization) for the negative values that may result from the image reconstruction and/or from random variations in detector readings. A second normalization method is background noise pre-normalization where background pixel values are masked. A third normalization method is kinetic pre-normalization where the contrast is improved to allow greater visualization of the activity in the image. Multivariate analysis such as PCA may then be applied to each slice of the dynamic PET images.

Abstract: The invention relates to an apparatus and a method for marshalling out individual objects (1) from a row of such objects (1). The apparatus includes two pusher arms (8) placed one on each side of the row of objects (1). The apparatus also includes two arrest pins (20, 21) on either side of the row, one front (20) and one rear (21). The apparatus further includes a linkage (13) on each side of the row, axially connected to a pusher arm (8) and interconnected with each other via a spring (14), respectively. The pusher arms (8) are moved, in a closed position, forwards with the aid of a piston and cylinder assembly (19) and, in this movement, marshal out the first object (1) in the row. Thereafter, the pusher arms (8) open in that they enter into abutment against the front arrest pin (20). The linkage (13) ensures that the pusher arms (8) assume an open position. The pusher arms (8) thereafter move backwards in the open position with the aid of the piston and cylinder assembly (19).
