Abstract: A computer implemented method comprising processing the unstructured objects of each record of records of a database for identifying a set of one or more values of attributes in the unstructured objects of the each record. The sets of unstructured attribute values of two records of the database may be compared for determining a similarity level between the two sets. It may be determined whether the two records are representing a same entity based on the comparison result.

Abstract: A system including a processor and a memory storing program instructions and a machine learning module. The machine learning module is configured for outputting one or more suggested data element change requests in response to receiving an initial data element change request. Execution of the program instructions causes the processor to receive the initial data element change request, receive the one or more suggested data element change requests in response to inputting the initial data element change request into the machine learning module, receive one or more subsequent data element change requests, detect if the one or more subsequent data element change requests contain the one or more suggested data element change requests, and provide an alert signal if the one or more suggested data element change requests are not detected within the one or more subsequent data element change requests.

Abstract: In an approach for authentication of a username, a processor maintains a mapping of usernames and realms. A processor receives a username and a time-based one-time password code (TOTP code) for the username based on an authentication application. A processor, upon receiving the TOTP code: determines a realm from the mapping based on the received username and the received TOTP; and requests an entry of a credential relating to the username in the realm. A processor, upon receiving of the requested credential, authenticates the username by determining that the received credential matches an expected credential for the realm.

Abstract: The present disclosure relates to a computer receiving a current training dataset. A first fraction of the training dataset comprises synthetic training data and a remaining second fraction of the training dataset comprising real-life training data. The real-life training data is user defined data and the synthetic training data is system defined data. A machine learning based engine is trained and may repeatedly be performed by using the current training dataset. In each iteration or a subset of the iterations, the training dataset is updated by adding real-life training data, thereby increasing the second fraction in the updated training dataset and reducing the first fraction of the synthetic training data.

Abstract: A computer device identifies a set of documents for classification. The computing device classifies documents of a first subset of the set of documents based, at least in part, on a text analysis of the documents of the first subset. The computing device trains a document classifier using, as training data: (i) results of the classifying of the documents of the first subset, and (ii) metadata associated with the documents of the first subset. The computing device classifies documents of a second subset of the set of documents by providing metadata of the documents of the second subset to the trained document classifier.

Abstract: The invention relates to a heat exchange system (1) including a heat exchanger (2) with a flow passage (210) arranged in a flow segment (21). For the exchange of heat between a transport fluid (3) and a heat transfer medium (4) flowing through the flow passage (210) in the operating state, the transport fluid (3) can be brought into flowing contact with the heat exchanger (2) via an inlet area (201) and can be led away again from the heat exchanger (2) via an outlet area (202). In accordance with the invention, for the determination of a degree of contamination (V) of the heat exchanger (2), a contamination sensor (5) in the form of a pressure sensor (5) and/or of a speed sensor (5) is provided with which a transport parameter (TK) can be determined which is characteristic for the flow of the transport fluid (3) from the inlet area (201) via the outlet area (202). Furthermore, the invention relates to a method for the operation of a heat exchange system (1).

Abstract: A heat exchanger arrangement is presented having at least one heat exchanger module (2), which includes a plurality of microchannel heat transfer elements (6.1, 6.2) and a plurality of heat exchange ribs (7.1, 7.2) which are connected to the microchannel heat transfer elements in a thermally conductive manner and which form air channels, and having a ventilation apparatus to generate an airflow (12?) in the air channels. The heat exchanger arrangement additionally includes a wetting apparatus to wet the microchannel transfer elements and/or the heat exchange ribs with liquid (10?). The heat exchanger arrangement is furthermore characterized in that the heat exchanger module or modules is/are arranged at an angle (?) with respect to the vertical.

Abstract: The invention relates to a heat exchange system with a heat exchanger (1, 101, 102) including an inflow area (2) and an outflow area (3), wherein for the exchange of heat between a transport fluid (4) and a heat transfer agent (5) flowing through the heat exchanger (1, 101, 102) in the operational state, the transport fluid (4) can be conducted via an arriving flow area (200) of the heat exchange system and via the inflow area (2) to the heat exchanger (1, 101, 102), can be brought into flow contact with the heat exchanger (1, 101, 102) and can be led away again from the heat exchanger (1, 101, 102) via the outflow area (3). In accordance with the invention the heat exchange system (100) includes an automatic cleaning system (7) for the removal of contaminants (6).
