Abstract:
Techniques described herein generally relate to etching graphene. The techniques can include disposing graphene on a patterned substrate, applying a resist to the graphene on the patterned substrate, curing the resist, and etching exposed portions of the graphene. Graphene composites including patterned substrates, graphene disposed on the patterned substrate, and a resist disposed on the graphene, are disclosed. Systems configured to perform the methods and/or make the graphene composites are also disclosed.
Abstract:
In some examples, sound verification may include a speaker device that may be configured to transmit sound at a dynamic volume level and a listening device that may be configured to receive the sound and provide feedback to the speaker device based on the received sound. The primary transceiver device may be further configured to adjust the dynamic volume level based on the feedback provided by the secondary transceiver device.
Abstract:
Technologies are generally described that relate to verification location determination for entity presence confirmation of online purchases. An example method may include determining whether a first risk level associated with a first candidate transaction is capable of mitigation to a defined level via physical verification of an entity associated with the first candidate transaction, wherein the first candidate transaction is determined to satisfy a defined risk profile. The method may also include, in response to determining that the first risk level associated with the first candidate transaction is capable of the mitigation to the defined level via the physical verification, generating location information indicative of a selected location for the physical verification.
Abstract:
Technologies are generally described for methods and systems effective to broadcast a message. In some examples, the methods may include receiving the message at a modulator. The modulator may receive a power signal configured to provide power to a closed conductive loop. The modulator may modulate the power signal using the message to generate a modulated power signal. The modulator may broadcast the message by sending the modulated power signal through the closed conductive loop. The modulated power signal, when passing through the closed conductive loop, may produce a modulated magnetic wave that includes an indication of the message. A receiver may be configured to detect the modulated magnetic wave from the closed conductive loop. The receiver may be configured to convert the modulated magnetic wave into the modulated power signal. The receiver may be configured to demodulate the modulated power signal to reproduce the message.
Abstract:
In a cloud computing environment, a server application hosted by a server may form a plurality of guilds by clustering multiple network terminals of similar performance together. The server application may then allocate computing resources to the guilds accordingly.
Abstract:
Technologies are described herein for allocating pages in a flash memory. Some example technologies may receive multiple data elements and a write request to write the multiple data elements to the flash memory. Example technologies may identify a correlation between a subset of the data elements based on correlation criteria. Example technologies may allocate neighboring pages of the flash memory for storing the subset of the data elements. Example technologies may write the subset of the data elements into the allocated pages.
Abstract:
Technologies are generally described for methods and systems effective to evaluate an interaction with a document. In some examples, a method may include identifying, by a processor, content data of the document. The processor may also map the content data of the document to an ontology to identify difference data. The difference data may reflect a difference between the content data and the ontology. The processor may also generate activity data, which may be effective to indicate the interaction with the document. The processor may also compare the activity data with the difference data. The processor may also determine a deviation based on the comparison of the difference data and the activity data. The processor may also evaluate the interaction with use of the deviation.
Abstract:
Food additives and food packaging materials having phase change materials are provided. Examples of phase change materials include gallic acid esters, tannic acid esters, fulvic acid, chitosan esters, hemicellulose derived esters, and the like. Methods of making and using the same are also provided.
Abstract:
Technologies are generally described for a resource allocation scheme for wireless communications. In some examples, a radio base station configured to communicate with one or more mobile devices may include a speed detection unit configured to detect moving speeds of the one or more mobile devices relative to a position of the radio base station; a resource allocation unit configured to allocate frequencies of one or more subcarriers based on the moving speeds of the one or more mobile devices; and a radio communication unit configured to communicate with the one or more mobile devices using the allocated frequencies of the one or more subcarriers.
