Abstract: The invention concerns a multilayer biaxially oriented white polyester film (adhesion, absence of chalking, opacity whiteness, reflectance, hydrolysis resistance & light stability) comprising three polyester layers: a core layer and two outer layers and contains TiO2 particles. In this film: at least one layer comprises a PET whose: number average molecular weight is within [18500-40000]; intrinsic viscosity IV is ?0.70 dL/g; and carboxyl group content is ?30 eq/T. Additionally, the core layer comprises TiO2 particles in a range of [0.1-40]% w/w; the intrinsic viscosity IV is between [0.5-0.85] dL/g; a small endothermic peak temperature is between 180-230° C.; and at least one light stabilizer is added in at least one of the outer layers, in a total concentration between [0.1-35]% w/w. The invention also includes the method for manufacturing such film and the laminate which is part of the back sheet of a solar cell.

Abstract: A product catalog system includes a product catalog having product offers received from various merchants. The product catalog system includes an analysis module that determines, for each merchant that provides product offers, which product offers are for products that are likely to be variants of one another based in part on titles of the products and assigns sets of product offers that are likely to be variants a merchant cluster identifier. The analysis module groups the product offers into product catalog entries based on the particular product that the offers are for. The analysis module determines which products are variants based on associations between the product catalog entries and the merchant cluster identifiers of the product offers included in the product catalog entries.

Abstract: An intrusion detection system (IDS) is capable of identifying the source of traffic, filtering the traffic to classify it as either safe or suspect and then applying sophisticated detection techniques such as stateful pattern recognition, protocol parsing, heuristic detection or anomaly detection either singularly or in combination based on the traffic type. In a network environment, each traffic source is provided with at least one IDS sensor that is dedicated to monitoring a specific type of traffic such as RPC, HTTP, SMTP, DNS, or others. Traffic from each traffic source is filtered to remove known safe traffic to improve efficiency and increase accuracy by keeping each IDS sensor focused on a specific traffic type.

Abstract: Disclosed are semicrystalline polyester oriented films having the properties of MD F5.gtoreq.18 daN/mm.sup.2, TD F5.gtoreq.10 daN/mm.sup.2, MDE.gtoreq.800 daN/mm.sup.2, TDE.gtoreq.400 daN/mm.sup.2, MDE+TDE.gtoreq.1200 daN/mm.sup.2, MDS 105.ltoreq.1.5%, MDS 150.ltoreq.5.2%, and TD St/TD F5.ltoreq.2.2. Also disclosed is a process for preparing semicrystalline polyester oriented films wherein an amorphous polyester film is successively subjected to a sequence of drawings comprising a lengthwise drawing in a single stage, a transverse drawing and a lengthwise drawing, wherein the first drawing mD is conducted at a temperature of between Tg +40.degree. C. and Tc -20.degree. C. and with a draw ratio .lambda.mD of between 1.2 and 3.
