Abstract: Technologies are provided for preventing abuse of software-defined datacenter networks. In some examples, an SDN abuse prevention module within a control layer of an SDN may use graph analysis rules and monitor network paths over time to detect and prevent abusive network conformation change command series. Instance-generated network paths may be analyzed to determine if the paths attempt to repeatedly traverse one or more sensitive network paths. If so, the paths may be implemented or denied based on, among other things, the time scale within which they attempt to repeatedly traverse the sensitive network paths.

Abstract: Technologies are generally described for methods and systems configured to increase a range of a network. In an example, a method for increasing a range of a first network may include sending a request by a communication device to a network device while the communication device is in a range of the first network. The request may include a request for discovery data that identifies the first network. The method may further include receiving, by the communication device, the discovery data. The method may further include broadcasting, by the communication device, information based on the discovery data when the communication device is outside the range of the first network and when the communication device is configured to communicate over a second network. The second network may be different from the first network.

Abstract: Technologies related to mobile device prevention of contactless card attacks are generally described. In some examples, a mobile computing device may monitor for electromagnetic signals at frequencies used for short range communications with contactless cards. Detection of such electromagnetic signals by the mobile computing device may indicate an attack attempt on a proximal contactless card. In response to detection of such electromagnetic signals, the mobile computing device may automatically generate a disruption signal effective to disrupt communications between contactless card readers and any proximal contactless cards, to thereby foil the attack before sensitive contactless card data is stolen.

Abstract: Technologies are presented for providing a suggestion list presenting options for posting information related to viewed content on a communication network. In some examples, a user may desire to contribute to posted content by adding comments and other relevant information. A system may identify one or more key terms included in the viewed content, and may compare the key terms with content, such as files, emails, websites, images and media content, on computing devices and web browser histories associated with the user to identify information that may be related to the viewed content. If the system identifies information related to the key terms of the viewed content, the system may present the identified information associated with key terms to the user, and may enable selection from a posting suggestion list for automatically posting.

Abstract: Technologies are generally described to correct color smear in an image generated using a sequential color system. In some examples, a correction system for see-through displays may use inertial movement data to compute the relative motion of the visual backdrop to correct color amplitudes and reduce or eliminate motion-caused color smear. A system according to embodiments may compute the angular motion of the background from inertial inputs, compute the pixel-angle equivalent motion time, and apply sequential color balancing across a time that corresponds to the pixel-angle motion time.

Abstract: Technologies are generally provided for conveying tree and index needs of a database by collecting and forwarding a statistically representative set of data requests so that a new datacenter can use its existing auto-learning and adjustment techniques to create local indices before receiving its first real or live requests. In some examples, requests at an origin datacenter may be collected to provide a small population of queries that are representative of a larger population of queries. Filters anonymizers may be employed to adhere to data sharing rules and restrictions while still allowing a new datacenter to build indices and test performance. Thus, the new datacenter may be trained asynchronously from another site and without actual data changing hands. Training and testing of destination database services may be completed before committing to customer migration.

Abstract: Technologies are generally described for providing full-motion animation-as-a-service. In some examples, short motion-capture segments may be captured from user motion user interface devices and stored in a database. When a full-motion animation is desired, a start pose and a target pose may be provided, and a multiple-path, multiple-iteration search through the database may be used to assemble the full-motion animation. Motion retargeting may be used to further refine the assembled hill-motion animation.

Abstract: The present disclosure relates to methods and apparatuses for forming a packaged application based on a selected subset of user-interface elements. One example method includes receiving a selection of a subset of user-interface elements of a packaged application at a device, determining data of the packaged application associated with execution of the subset of user-interface elements, and packaging the data to form another packaged application for executing the subset of user-interface elements.

Abstract: Technologies are generally described to construct a hash table for utilization in a recognition of a target object in an image. According to some examples, a system to serve topical image recognition hash tables to user devices may construct a lookup hash table union from disjoint hash tables of particular objects. For example, a server may receive a request for a category or list of items, interpret which objects to send, and compose a joined image hash lookup table from the disjoint objects that match the target set. In other examples, the category information may be expanded into an object list and hash collections associated with the object list may be retrieved.

Abstract: Technologies are generally described herein for managing heat within a phase change memory (PCM) structure utilizing electrocaloric effect materials. Some example PCM structures may include an electrocaloric effect material layer thermally coupled to an array of PCM cells. The electrocaloric effect material layer may be segmented so that activation of each segment is coordinated with a subset of the PCM cells within the array. While excess heat emanates from a PCM cell during memory operations, a corresponding electrocaloric effect material segment may be activated to decrease the thermal resistance of the electrocaloric effect material, which transfers the excess heat away from the neighboring PCM cells.

Abstract: Technologies are generally described for providing instructional media for assembly of a product from multiple components. In some examples, a standalone or web-based application for assisting with assembly of items may be informed of the state of the ongoing unpacking and/or assembly through optically, wirelessly, or comparably readable tags associated with the individual components of a disassembled item. Based on received data on state of assembly and which parts a user is accessing, the application may select appropriate instructional media, including detection of when assembly has gone wrong in order to coach the user through the assembly process and/or corrections.

Abstract: Technologies are generally described herein for electrocaloric effect heat transfer devices and methods effective to facilitate thermal energy transfer while mitigating mechanical stresses caused by expansion or contraction of electrocaloric effect material layers during thermal energy transfer operations. Some example heat transfer devices may include heat transfer stacks with at least two electrocaloric effect materials. Expanding electrocaloric effect material and contracting electrocaloric effect material are utilized to cancel the aggregate longitudinal dimensional change during application of an electric field. Some example heat transfer devices may utilize segmented electrocaloric effect material layers with stress relief gaps separating segments to mitigate delamination stress caused by lateral expansion or contraction of the electrocaloric effect material.

Abstract: Technologies are generally described for systems, methods, and devices related to core affinity bitmask translation. An example system may include first, second, third and fourth cores, and a dispatcher. The dispatcher may be configured to receive a first request where the first request include a core affinity bitmask and instructions. The core affinity bitmask can identify at least the first core and the second core. The dispatcher may be configured to determine a first affinity between the first core and the second core. The dispatcher may then identify the third core and the fourth core as having similar affinity to achieve a substantially similar performance. The dispatcher may also be configured to generate a second request that includes a translated core affinity bitmask. The translated core affinity bitmask may be effective to identify the third core and the fourth core as appropriate cores to execute the instructions.

Abstract: Technologies related to migration in place are generally described. In some examples, software and/or data associated with a platform customer can be “migrated” to a new platform while allowing the platform customer's software and/or data to remain on same hardware. A data center and/or Infrastructure as a Service (IaaS) provider may be configured to support migration in place for example by providing hardware identifiers upon request, providing platform identifiers upon request, providing platform compatibility information upon request and/or approving platforms for migration in place operations, deploying platform modules to migration in place hardware, providing user session support during migration in place operations, and/or performing security operations.

Abstract: Technologies are generally described for masking power usage of co-processors on field-programmable gate arrays. In some examples, one or more moat brick circuits may be implemented around a co-processor loaded on a held-programmable gate array (FPGA). The moat brick circuits may be configured to use negative feedback and/or noise to mask the power usage variations of the co-processor from other co-processors on the FPGA.

Abstract: Technologies are generally described to implement intrusion detection based on smart power background. In some examples, upon detection of an attempt to access a resource, a power line ambiance may be determined at a location of a device on which the attempt to access the resource is executed. The power line ambiance may be based on a connection of the device and/or one or more other devices at the location to a power line. The captured/received power profiles may identify device signatures enabling generation of a digest of the location. An intrusion detection system (IDS), may receive the digest of the location and compare the digest to previous digests associated with an authorized client of the resource to evaluate an authenticity of the attempt. If the authenticity of the attempt is suspicious, the IDS may elevate security by employing one or more verification levels and/or one or more authentication techniques.

Abstract: Technologies are provided for function-targeted virtual machine switching. In some examples, function usage times on a virtual machine (VM) may be profiled by a virtual machine manager (VMM) and used to manage VM switching in order to preferentially switch VMs during specific targeted functions. The targeted functions and/or VM switching preferences may be adjusted over time in order to provide switching unpredictability, for example to frustrate side-channel attackers by forcing the attackers to gather data for much longer periods of time (e.g., weeks or months) if they want to detect or attack.

Abstract: Technologies are described herein to use snapshot backups for licensing. Some example technologies may access a snapshot backup that is taken during an execution of a virtual machine on a server. One or more snapshot backups may be examined to detect applications that executed on the server at a time the snapshot backup was taken. A determination may be made as to what applications that were identified are subject to a license. Licensing information may be provided that includes information associated with the one or more of the applications that are subject to the license.

Abstract: Technologies are generally described for pausing virtual machines using API signaling. In some examples, active threads in a VM may be listed on a registered thread list. When the active threads in the VM perform external API calls, they may provide wait messages, which may then be compared with the registered thread list to determine if the VM should be paused. Subsequently, one or more replies to the external API calls may be received and used to determine if the VM should be reactivated.

Abstract: Technologies are generally described for a system for detecting the presence of gas in the intraperitoneal space of the abdominal cavity and indicating anastomotic leakage. A sensing device may be implanted inside the abdominal cavity of a body near the location of an anastomosis. The sensing device may utilize a sensor configured to detect gas presence and measure the concentrations of gases, including hydrogen sulfide and/or methane, within the intraperitoneal space. The sensing device may be configured to transmit gas detection information to an external wireless communication device, and the wireless communication device may be configured to generate an alert if a gas concentration level rises above a predetermined acceptable level.
