Abstract: Gold farming refers to the illicit practice of gathering and selling virtual goods in online games for real money. Although around one million gold farmers engage in gold farming related activities, to date a systematic study of identifying gold farmers has not been done. Here data is used from the Massively Multiplayer Online Role Playing Game (MMOG) EverQuest II to identify gold farmers. This is posed as a binary classification problem and a set of features is identified for classification purposes. Given the cost associated with investigating gold farmers, criteria are also given for evaluating gold farming detection techniques, and suggestions provided for future testing and evaluation techniques.

Abstract: An anthropomorphic phantom used as a training tool by healthcare workers for learning ultrasonic imaging procedures. The phantom is made of a moldable, elastomeric tissue-simulating chemical composition that may be easily processed to create an anthropomorphic phantom: that has the “look and feel” and self-sealing characteristics of human tissue. During the mixing processes, scattering agents and pigments may be added to provide a phantom that simulates the sonographic characteristics on living tissue. The phantom body may contain objects and empty or liquid filled cavities and conduits that simulate normal internal structures and abnormal artifacts and conditions. In one embodiment, hollow rods are disposed longitudinally inside the primary mold that forms blood vessels inside the phantom. When the phantom is removed from the primary mold, the hollow rods are removed thereby forming a hollow conduit.
