A training model for malware detection is developed using common substrings extracted from known malware samples. The probability of each substring occurring within a malware family is determined and a decision tree is constructed using the substrings. An enterprise server receives indications from client machines that a particular file is suspected of being malware. The suspect file is retrieved and the decision tree is walked using the suspect file. A leaf node is reached that identifies a particular common substring, a byte offset within the suspect file at which it is likely that the common substring begins, and a probability distribution that the common substring appears in a number of malware families. A hash value of the common substring is compared (exact or approximate) against the corresponding substring in the suspect file. If positive, a result is returned to the enterprise server indicating the probability that the suspect file is a member of a particular malware family.

The present invention includes methods for producing magnetic nanocrystals by using a biological molecule that has been modified to possess an amino acid oligomer that is capable of specific binding to a magnetic material.

A mobile phone terminal with a camera function includes a camera hardware section having an image sensor and a camera lens, an instruction input section for inputting an instruction to start image capturing, an illumination sensor which is arranged on an outer surface of a housing and detects an ambient illumination value while a mobile phone function is activated, and an image capturing start control section. The image capturing start control section sets camera driver software into a standby state after starting it while the mobile phone function is activated. When an instruction to start image capturing is inputted from the instruction input section, the image capturing start control section determines an exposure value used for image capturing by using the detected illumination value, restores the camera driver software, and causes the camera hardware section to perform image capturing using the exposure value.

In this way, according to the present invention, the refresh cycle according to the auto-refresh mode and the refresh cycle according to the self-refresh mode can be controlled independently. Therefore, refresh operation considering the characteristic of each mode can be executed.

A virtual tape storage system includes an original virtual tape library for storing data and includes snapshot virtual tape library (SVTL). The SVTL includes a snapshot of the data stored in the original virtual tape library. A host is operable to receive the snapshot data from the SVTL to perform a disaster recovery test of the original virtual tape library. The SVTL is generated from the original virtual tape library using a copy-on-write snapshot process. In an embodiment, the original virtual tape library stores the stored data on a number of virtual tape volumes (VTVs), and the SVTL includes a snapshot of those VTDs and VTVs which are required for a disaster recovery test of the original virtual tape library. In this case, the host uses the SVTL to perform the disaster recovery test of the original virtual tape library.

A computer implemented method and system for filtering incoming electronic messages based on user objectives is disclosed. For example, automated assistance can be provided in realizing a user objective of filtering electronic mail (e-mail) messages associated with a “conversation” thread. The electronic message filtering system can receive an e-mail message, examine attributes or characteristics of the e-mail message, determine if a rule has been established for messages with the characteristics of the incoming message, and if there has been a rule set up, automatically implement an action in accordance with the rule. For example, when electronic messages with particular information in the header (e.g., a particular subject) are received, the messages are automatically moved to a designated trash folder. Additionally, finer granularity of message management can be achieved (e.g., an action is automatically implemented to display a message from a particular sender at the top of a list).

A vehicle end structure mainly includes a vehicle bumper fascia and a grille assembly. The vehicle bumper fascia includes a sill portion and a receiving member extending from the sill portion.

The support member is disposed in the channel of the receiving member to limit movement of the inner grille member in a direction normal to the forward vehicle facing direction. The outer grille member is disposed on a forward vehicle facing side of the inner grille member to conceal the support member from view in the first direction.

Systems and methods for providing and managing docked browser tabs are provided. In one exemplary method, a webpage may be open in a first tab in a browser application on an electronic device. In response to one or more inputs, the state of the webpage in the first tab may be changed. A user may request to open the webpage in a second tab that is different from the first tab; and it may then be determined whether the first tab is a docked tab and whether the webpage is associated with a docked tab. In accordance with a determination that the webpage is associated with a docked tab and that the first tab is a docked tab, the webpage is presented with the state of the webpage in the first tab. In accordance with a determination that the webpage is associated with a standard tab and that the first tab is not a docked tab, the webpage may be presented in the second tab with a state different from the state of the webpage in the first tab.

A system and method for finding electromigration (EM), self heat (SH) and voltage drop/droop violations of an integrated circuit, when its design and electrical characterization are not complete, are disclosed. The method includes analyzing polygons for average, root-mean-square (RMS) and Ipeak current densities and voltages of a mask layout block and obtaining one or more electromigration, self heat and/or voltage drop/droop rules associated with the polygon from a technology and an external constraints file. The system reads the available design simulation data to calculate the average, RMS and Ipeak current densities and voltages, and estimates the current densities and voltages when no data available. The method also includes topological analysis of the mask layout and analysis of the electrical circuit elements of the design. The method finds the polygons where the current densities are higher than electromigration and self heat rules as taken from technology or external constraints file. The method also finds the polygons where the current densities are higher than in other polygons, by the defined threshold. The method also finds the nodes where the voltage drop/droop is larger than the rule. The method also finds the polygons where the voltage drop/droop is larger than in other polygons by the defined threshold. The method and system work on GDSII, GDSIII format files and on industry standards layout editors' database.

Digital content from a source (e.g., a file or a stream), is striped and encoded in parallel over a cluster of Storage Systems. The encoding ensures that subsequent retrieval of the data succeeds even when some members of the cluster of Storage Systems are lost or when errors in communication result in the loss of some IP packets. Host Map File (HMF) data is produced that describes fully how to retrieve the content, including the encoding parameters, the cluster of Storage Systems and the striping of the encoded data. This HMF data is then inserted as the header of every encoded file on the cluster of Storage Systems. The HMF data is the only way the encoded files can be reassembled into a meaningful whole. The original content is retrieved by requesting its data from the cluster of Storage Systems. In each Storage System, a decoder parses the HMF data and transmits the striped data to the requestor. The decoders cooperate to dynamically detect erasures and to reconstruct the missing data. The system is self-healing as new Storage Systems are able to reconstruct data missing due to the loss of any Storage Systems from the cluster without impeding concurrent encode and decode transactions.

A method starts when a print job is received from a workstation. The print job includes user printing options and an identification of an initial printer. The method ranks the abilities of the available printers to process the print job to identify the best printer for the print job according to, among other items, printer proximity. If the initial printer identification creates a print policy violation, the method presents a question/statement to the workstation (to the user through the workstation) regarding whether the print job should be redirected to the best printer and provides an automated resubmit option at the workstation. If the resubmit option is activated, the method automatically submits the print job to a different available printer, without requiring the user to manually input the printing options.

The invention discloses a local descriptor-based three-dimensional face recognition method, which comprises the following steps of: (1) preprocessing a face library model and a testing face model by face cutting, gesture normalization and dilution, and finally establishing a face principle axis coordinate system by taking the tip of nose as a center; (2) extracting equidistant contour lines from the face library model and the testing face model, extracting sixteen contour lines equidistant to a point of the tip of nose by taking the point of tip of nose as a center, and resampling to acquire the same number of sampling points; (3) latticing the face library model and the testing face model, and extracting a local projection area on the acquired sampling points in the step (3) as a local characteristic; (4) establishing one-to-one correspondence between the sampling points in the same sequence on the face library model and the testing face model, and comparing local characteristics of corresponding points; and (5) taking Euclidean distance of the local characteristics between the corresponding points as similarity, and selecting a face which is most similar to the testing face from the face library as a recognition result.

An internal locking system is disclosed, which utilizes electromechanical locking devices to lock and unlock lockable openings.

Mixed-phase TiO₂ nanofibers prepared via a sol-gel technique followed by electrospinning and calcination are provided as photocatalysts. The calcination temperature is adjusted to control the rutile phase fraction in TiO₂ nanofibers relative to the anatase phase. Post-calcined TiO₂ nanofibers composed of 38 wt % rutile and 62 wt % anatase exhibited the highest initial rate constant of UV photocatalysis. This can be attributed to the combined influences of the fibers' specific surface areas and their phase compositions.
