Title: Financial portfolio risk management
Inventor: SLUTSKY STEPHEN B
IPC: G06Q40/00
Filed: 2002-08-09
Abstract: A financial portfolio risk modeling system operates in a collaborative computing environment between a user (110) and a portfolio development system (182). The portfolio generating system models the user's personal investment parameters (174) into a user profile in terms of the user risk tolerance level, user investment style, and user bull/bear attitude. The system further calculates Value At Risk (VAR) values for the user. The system filters various securities based on their VAR and Beta values and presents two lists of filtered securities, with opposing Beta values, matching the user profile. The system enables the user to swap securities in and out of his/her existing portfolio. The model also generates an ideal portfolio based on the user profile. The system presents the user with an estimated value of his/her portfolio, based on a regression formula as well as a possible best and worst scenario on a statistical formula.

Patent CA-2467296-A1 (CA)
Inventor: SULZER HANS DIETRICH
IPC: B32B5/24
Filed: 2004-05-14
Abstract: In order to reduce the heat transfer coefficient of coated building panels, the coating and the building panel have a high voidage. This high voidage can be obtained by using a fiber mat and a porous coating applied to the fiber mat. The porous coating includes porous glass particles and a low amount of a binder. The porous glass particles are held together by binder bridges, including a silicate binder and a low amount of an organic dispersion binder, for example an polymeric styrol acrylate. The partial volume filled by the binder bridges is small and therefore there is a remarkable first empty partial volume in between the porous particles. A second empty partial volume is located within the glass particles. The total volume of all pores of the glass particles is a relevant part of the total coating volume. This second empty partial volume is a very good therma l isolation because the individual pores are small and to a high percentage closed chambers not connected to the ambient. The silica binder and the high voidage in the coating provide a high fire-resistance.

IPC: G16B25/10
Filed: 2003-02-11
Abstract: Potential functions of one or more genes are inferred from gene expression measurements. A method involves assembling a distribution of expression level measurements for one or more genes. The method also involves calculating a significance value for each of the expression level measurements. The significance values determine which gene expression samples are classified as relevant and which are classified as irrelevant. The two sample classes are compared to each other to determine the non-overlapping parameters from the gene expression data between them. The non-overlapping parameters are used to indicate gene function of an unknown gene.

Abstract: An improved container designed to provide all of the foregoing attributes (including light weight, low cost, ease of use and carrying, and climatic tolerance) while also presenting a virtually impenetrable barrier to animals. One exemplary embodiment comprises a highly resilient, lightweight, one-piece polymer (polycarbonate) body or shell having a large-diameter aperture disposed at one end. A threaded, partially flexible lightweight polymer cap element mates with the body; the cap element comprises a tamper-resistant configuration with locking features which prevent rotation of the cap with respect to the body past a certain point. A ridge is foamed on the body along the mating region of the cap, the ridge acting to prevent any animal (or human for that matter) from being able to insert anything (e.g., claws) under the cap when installed to pry it off. The locking features, ridge, body, and cap coordinate to make the container pliable enough to distort without opening, yet resilient and rugged enough to prevent permanent deformation, fracture, or cracking even under the weight (and motive forces) of a fully grown bear.
