Abstract:
A power generation system includes at least one generator having at least two sets of stator windings, an active rectifier comprising power cell based modular converters associated with each set of generator windings. Each set of windings is connected to an AC voltage side of the associated active rectifier, with each active rectifier having a positive DC voltage output and a negative DC voltage output. The DC voltage outputs of active rectifiers are connected to each other in series. A medium voltage DC (MVDC) collection network comprises positive pole cables and negative pole cables, wherein each positive pole cable is connected to the positive DC voltage output of a first active rectifier and each negative pole cable is connected to the negative DC voltage output of a last active rectifier. A substation receives the negative and positive pole cables of the MVDC collection network for further transformation and transmission.

Abstract:
Techniques are disclosed for generating an ensemble model from multiple data sources. In one embodiment, the ensemble model is generated using a global validation sample, a global holdout sample and base models generated from the multiple data sources. An accuracy value may be determined for each base model, on the basis of the global validation dataset. The ensemble model may be generated from a subset of the base models, where the subset is selected on the basis of the determined accuracy values.
Abstract:
In one exemplary embodiment a network node (such as a base station BS) determines that a plurality of user equipments UEs are available for use as mobile relays MRs, and selects a subset of the plurality of UEs and configures the subset of the plurality of UEs as MRs. In another exemplary embodiment, an indication is sent (for example from a UE) that a UE is willing to operate as a MR, a response is received that the UE is selected to be a MR1 and then periodically there is sent a beacon advertising that the UE is a MR. In this manner UEs are pre-configured in a cell as MRs, regardless of any specific UE need for relay services. Any UE later needing relay service listens for the beacon. The BS can limit which UEs it pre-configures as MRs to avoid closely spaced UEs being both active MRs. Locations need not be signaled.
Abstract:
Provided are techniques for imputing a missing value for each of one or more predictor variables. Data is received from one or more data sources. For each of the one or more predictor variables, an imputation model is built based on information of a target variable; a type of imputation model to construct is determined based on the one or more data sources, a measurement level of the predictor variable, and a measurement level of the target variable; and the determined type of imputation model is constructed using basic statistics of the predictor variable and the target variable. The missing value is imputed for each of the one or more predictor variables using the data from the one or more data sources and one or more built imputation models to generate a completed data set.
Abstract:
A method can include receiving at a cluster head, a multicast/broadcast packet from a base station. The method can also include monitoring, at the cluster head, to detect whether any members of a cluster of the cluster head responds to the multicast/broadcast packet with a negative acknowledgment directed to the cluster head. The method can further include, when a result of the monitoring is no detection of any negative acknowledgments, and the cluster head successfully received the multicast/broadcast packet, sending, by the cluster head, a general acknowledgment of the multicast/broadcast packet to the base station.
Abstract:
Examples of the present disclosure provide an ACK/NACK/SR resource mapping method and an apparatus. According to the technical solution provided by the examples of the present disclosure, in a system including a terminal utilizing a first type protocol and a terminal utilizing a second type protocol, the base station allocates the ACK/NACK/SR resources corresponding to the second type protocol in an area outside of the ACK/NACK/SR resource area reserved for the terminal utilizing the first type protocol, and informs the terminal utilizing the second type protocol of the allocation information of the corresponding ACK/NACK/SR resources. Thus, the terminal utilizing the second type protocol may transmit feedback information via the corresponding ACK/NACK/SR resources.
Abstract:
It is provided an apparatus, including base station means to provide a base station functionality using component carriers; neighbor detecting means to detect a neighboring base station; informing means to inform a coordinating device about the neighboring base station; willingness setting means to set a willingness to perform self-tuning based on a respective long-term priority for each component carrier, wherein the long-term priorities are received from the coordinating device, and the willingness is only set if the long-term priorities are not in contradiction to an actual requirement, willingness providing means to provide an indication of the willingness to the coordinating device; and self-tuning means to perform self-tuning if an agreement statement is received from the coordinating device, wherein, as a result of the self-tuning, a usage of each component carrier by the base station means is based on the received long-term information and the actual requirement.
Abstract:
Improved method and system for performing three-dimensional shape inspection by: projecting a pattern of light onto an object of interest with a projector, the pattern of light being constituted by a plurality of symbols of different shapes; capturing an image of the illuminated object with an image capturing device; determining the 3D shape of the object from the image data and the projected light pattern with a processor using triangulation. The pattern of light is projected in an omnidirectional plane by means of a first mirrored surface having hyperbolic shape to provide an alternative to traditional monochromatic light based patterns.
