Northeastern University's Center for Research Innovation posted this:Automatic Tool for Scouring the Internet and Generating Names Linked to Illegal Activities to Facilitate Detection and Reporting of Suspicious ActivitiesFinancial institutions are actively required to track clients engaged in illegal/suspicious activities in order to understand their overall risk exposure. Such activities are currently performed manually. Moreover, there is a lack of suitable product(s)/technique(s) in the market for real time, adverse media scanning. Additionally, the currently used products/techniques are associated with many possible limitations such as limited name matching parameters, imprecise transaction filtering rules, presence of false positives, significant human interventions, and absence of appropriate platforms for information sharing. The invention discloses a novel system/method to facilitate detection and reporting of suspicious/illegal activities over the internet.
Northeastern University's Center for Research Innovation posted this:REAL-TIME ANOMALY DETECTION OF LARGE, DENSE CROWD BEHAVIOR, FROM VIDEO AND MULTI-SENSOR INFORMATIONCurrent methods for detection of crowd behavior are based on tracking individuals or virtual particles. Such assessments are highly prohibitive, preventing the real time and efficient analysis. Other approaches use comparisons of individual behaviors with normal patterns. However, these approaches are tedious and unreliable. This novel procedure allows for the use of a sensing system (comprising video and multi-sensor information) for real-time detection of the behavior of a large, dense crowd.
Northeastern University's Center for Research Innovation posted this:A New E-Field Writable Magnetic Random Access Memory Based on MultiferroicsCurrently, magnetic random access memories (MRAMs) use a magnetic field to control corresponding magnetic states. Such systems are comparatively bulkier and are associated with high-power consumption. With ever changing life-style; the demand for faster, smaller and ultra-low power memory systems is significantly increasing. This approach allows for the development and use of a novel electric field (E-Field) controllable MRAMs based on multi-ferroics.

PhotonDelta posted this:Method and arrangement for microwave signals transmission through a multimode fiberThe invention provides a solution for the direct transportation of analog electrical signals, in particular radio signals, via a multi-mode optical fiber, so that it will be possible to transmit the transferred radio signal without any further signal processing at the base stations. Especially if a large number of base stations are used, as in the case of wireless networks as explained in the foregoing, it will be advantageous to keep the base stations as simple as possible. Not only does this provide a direct financial benefit as regards the cost of the base station itself, but it also enables a considerable saving on maintenance and repair costs of the network.
