Abstract: Monitoring transaction activity for system requests for a set of entities authorized to request services of a system is described. Entities with high feature values for respective features of the set of activity based features are identified to produce a set of outlier entities. The outlier entities are filtered from the set of entities. A set of clusters are created from the filtered set of entities based on the set of activity based features so that each entity in the filtered set of entities is assigned to a cluster. Values for the set of activity based features are established for each cluster. A risk is assigned for each cluster based on the values of one or more of the set of activity based features. Each of the filtered set of entities are monitored based on the risk assigned to the respective clusters to which the respective entities belong.

Abstract: A method, a computer program product, and a computer system determine a qualified exchange. The method includes receiving a request for a status of an exchange. The method includes determining the status of the exchange using a qualification analysis. The qualification analysis includes a plurality of prevailing factors and a multi-step analysis. Satisfaction of one of the prevailing factors automatically qualifies the status of the exchange as the qualified exchange. the multi-step analysis includes a plurality of tests. Satisfaction of each of the tests qualifies the status of the exchange as the qualified exchange. The method includes generating and transmitting a response indicative of the status of the exchange.

Abstract: The invention relates to a delivery system for delivering a stent (S) into a body vessel of a patient, comprising a flexible catheter tube (3) having a proximal and a distal end for delivering the stent (S) to a predetermined location in the body vessel and a catheter tip (1) having a longitudinal direction, which is disposed at the distal end of the catheter tube (3). The catheter tip (1) has a stent chamber (150) to receive the stent (1). The catheter tip has a first pressure chamber (20, 22). In the catheter tube (3) a first fluid channel (31) extends from the proximal end to the first pressure chamber (20, 22) of the catheter tip (1). The volume of the first pressure chamber (20, 22) can be enlarged by delivering a first fluid from the first fluid channel (31) to the first pressure chamber (20, 22), such that the stent (S) is released from the stent chamber (150) at the predetermined location in the body vessel.
