Abstract: A method for use in over-the-counter (OTC) financial markets to selectively generate and transmit crossing market alerts to market participants (e.g., market makers or liquidity providers). The method includes providing an alert generation system with a processor executing code to provide a crossing markets module. The method also includes, with the crossing markets module, receiving from a data source a set of market data defining pricing for a financial instrument, such as a bond, credit default swap (CDS) or other swap, or loan. Then, the method includes receiving a quote for the financial instrument from a market maker. The method involves comparing pricing data in the quote with the pricing for the financial instrument defined by the market data to identify a crossing markets event. The method includes generating a crossing markets alert when a set of alert generation rules, including surpassing an economic threshold, are met.

Abstract: Voltage sources produce desired current patterns in an ACT-type Electrical Impedance Tomography (EIT) system. An iterative adaptive algorithm generates the necessary voltage pattern that will result in the desired current pattern. The convergence of the algorithm is shown under the condition that the estimation error of the linear mapping from voltage to current is small. The simulation results are presented along with the implication of the convergence condition.
