Abstract: A method adapts network intrusion detection. The method includes: a) deploying a network traffic capture system and collecting network packet traces; b) using a network audit tool, extracting features from the collected network packet traces; c) feeding the extracted features as unlabeled data into a representation function, and, utilizing the representation function as an unsupervised feature learning algorithm, learning a new representation of the unlabeled data; d) providing a labeled training set capturing examples of malicious network traffic, and, using the learned new representation of the unlabeled data, modifying the labeled training set to obtain a new training set; and e) using the new training set, training a traffic classification machine learning model.

Abstract: A detection rules generation engine includes an initial population creation subsystem configured to receive filtered network traffic instances from a network tap and to build an initial population of decision trees having nodes which are sorted based on an information gain of network features of the traffic instances. A parents selection subsystem is configured to select two individuals from the population based on a selection probability. A depth selection subsystem is configured to select a depth among the nodes of the decision trees. A parents crossover subsystem is configured to apply a crossover operation on the selected individuals. A parents mutation subsystem is configured to apply a mutation operation on the selected individuals. A population replacement subsystem is configured to generate a next population.

Abstract: Method for supporting a reputation mechanism in a network including one or more domains with one or more users being connected to the domains, one or more Identity Providers that manage identity information, and at least one entity that functions as Web Service Consumer for the users. When a user requests a Web Service Consumer of one of the domains for a web service provided by a Web Service Provider, the requested Web Service Consumer requests its known Identity Providers regarding a recommendation of the Web Service Provider. The Identity Providers function as recommendation aggregators by collecting reputation assessments of the Web Service Provider from entities registered on the Identity Providers who return an aggregated recommendation to the requested Web Service Consumer that determines a trust assessment about the Web Service Provider. A privacy homomorphism is employed for providing an encrypted exchange of recommendation related information.

Abstract: Method for operating a smart grid including a plurality of smart meters configured to monitor at least one physical measured quantity and to provide measurement results of the at least one physical measured quantity to a central entity, includes the following steps: partitioning the smart grid into groups of smart meters, such that each of the smart meters belongs to exactly one group, all smart meters of one of the groups encrypt their measured value by applying a bihomomorphic encryption scheme and send it to the central entity, one smart meter per group is designated as key aggregator to which all smart meters of that group send their key employed for the encryption, the key aggregator computes the aggregation of all received keys and sends the aggregated key to the central entity, the central entity aggregates all received encrypted measured values and decrypts the aggregation by employing the aggregated key.

Abstract: A method coordinating home services is provided, including receiving a request for home services from a customer over a network and forwarding the request from the customer to a home services coordinator over the network. A reputation system assists the home services coordinator to select a service provider based on customer needs, preferences, and a reputation of the service provider. Information sufficient to permit the service provider to select a home delivery provider that can satisfy customer needs is provided to the selected service provider over the network. The selected home delivery provider is provided with access to customer data and with access to a customer physical system over the network, to provide the service. Feedback is requested from the customer after the service has been delivered, and is used in the reputation system to update the customer preferences and the reputation of the service provider.

Abstract: A vertical symmetrical vibrating mill that includes a top vibrating tube and a bottom vibrating tube. The top vibrating tube and the bottom vibrating tube are connected so as to form a single vibrating body. The single vibrating body is supported and/or suspended by a support element. The top vibrating tube and the bottom vibrating tube are located on opposite sides of, and are substantially symmetrical about, a reference plane of symmetry. The top vibrating tube and the bottom vibrating tube each have a common axis that is perpendicular to the reference plane of symmetry. In operation, the vibrating mill is preferably arranged such that the common axis of the top vibrating tube and the bottom vibrating tube is oriented in a direction corresponding to the direction of gravity. The vertical symmetrical vibrating mill also includes a plurality of exciter elements including at least one exciter element connected to each of the top vibrating tube and the bottom vibrating tube.

Abstract: The present invention is a synthetic-core construction panel having a polyurethane core encased by a metal grid. The grid system comprises a first series of metal bars disposed in parallel to each other, equally spaced apart around the circumference of the core; a second series of metal bars, disposed in parallel to each other and perpendicularly to the first series of metal bars, equally spaced apart, are also disposed around the circumference of the core; and a plurality of diagonal cross-member reinforcements welded at their edges to each connecting point between the first series of metal bars and the second series of metal bars. The metal grid serves as a surface accepting masonry/plaster as a finish for the panel after installation. An apparatus for making the synthetic core construction panels is also described and claimed.
