Abstract:
Thermostatic heating or cooling materials and method for making and using the materials are disclosed. The thermostatic materials may be usable as packaging material and may include a mixture of at least two materials which exhibit a liquid crystalline (LC) phase, or mesophase. Mixtures of two or more compatible LC components may provide a tunability for both operating temperature (temperature control) and latent heat of transition (cooling capacity).
Abstract:
Composite foams having cells containing shape-stabilized phase change material (ss-PCM) particles are described. Composite foams may be made by contacting a plurality of ss-PCM particles and one or more pre-polymer reactants, wherein each ss-PCM particle can form a nucleation site for foam cell generation. The composite foams may be used in regulating the temperature of an article wherein the foam undergoes a phase transition as the surrounding temperature of the article approaches the foam's phase transition temperature. The thermostatic material may exchange heat with the article during the phase transition, resulting in regulation of the temperature of the article. The composite foams may be used as a thermostatic packaging material having a cavity for storing goods.
Abstract:
In some examples, a distributed file system is described. The distributed file system may include multiple data nodes and a director unit. The multiple data nodes may each include one or more data blocks. The director unit may include multiple master nodes configured in a peer-to-peer distributed architecture and operably coupled to the multiple data nodes. Each of the master nodes may be configured to receive a task related to managing data with respect to the distributed file system; to manage a distribution of the task among one or more of the plurality of master nodes; and to communicate a task status and a status of at least a part of the distributed file system to each of the other master nodes.
Abstract:
In some examples, a method to monitor an animal may include determining a physiological status of the animal based on a tattoo that includes intelligent ink injected into skin of the animal. The method may also include recording the physiological status of the animal. The method may also include, in response to the physiological status indicating a physiological event or condition, triggering an alert to address the physiological event or condition.
Abstract:
Technologies are generally described for methods and systems effective to determine traffic volume of a domain name server caused by a host domain. In some examples, a host domain may store page view data that relates to page views requested at the domain name server. The host domain may receive a first query for a resource associated with the host domain. The host domain may add an instruction to the resource to produce a modified resource and send the modified resource to a device. The modified resource may generate a second query that may be used to determine traffic volume. The device may receive the modified resource, and generate the second query that includes an identification of the domain name server. The host domain may receive the second query, detect the identification, and update the page view data. The host domain may determine traffic volume based on the page view data.
Abstract:
Technologies are generally described for providing a transition between predictive and mobile-assisted spectral allocation. In some examples, wireless devices may be enabled to determine adequacy of their allocated spectral path to meet their communication needs by analyzing signal-to-noise ratios (SNRs) of their assigned sub-carriers. If a wireless device determines a current sub-carrier to be inadequate based on the analysis, d may send information associated with preferred sub-carriers to a base station. The base station may determine one or more nearby good clusters based on a comparison of a sequence of received preferred sub-carriers and the spectral paths represented by the nearby duster centers, and select a re-allocated spectral path with shortest information distance to the sequence of preferred sub-carriers.
Abstract:
Technologies are generally described for systems, devices and methods effective to migrate a virtual machine between computing devices. A first and second node may be identified effective to access the virtual machine at a first computing device. First and second vectors related to the first and second nodes, respectively, may be determined. The first and second vectors may relate to values of a parameter. The parameter may relate to communication between the nodes and the first computing device. The vectors may form a distribution. A feature of the distribution of the vectors may be determined. A first magnitude between the first computing device and the feature may be determined. A second magnitude between the second computing device and the feature may be determined. The virtual machine may be migrated from the first computing device to the second computing device if the second magnitude is less than the first magnitude.
Abstract:
Functionalized microspheres for being dispersed in matrix materials to reduce the density and weight of the materials may be configured to include a covalently bound surface component which is configured to covalently bond with the matrix material so that when combined with the matrix material a strong, light-weight matrix material may be produced.
Abstract:
Technologies are generally described for a data management scheme. In some examples, a method may include displaying, by a client device, a representation of a data item received from a server; transmitting, by the client device, to the server, a request to access the data item and information regarding the request to access, in response to a user input; updating, by the server, the representation of the data item to further include the information regarding the request to access; and displaying, by the client device, the updated representation of the data item received from the server.
Abstract:
Techniques described herein generally include methods and systems related to designing and operating a DRAM device that has significantly reduced refresh energy use. A method for designing a DRAM optimizes or otherwise improves the DRAM for energy efficiency based on a measured or predicted failure probability of memory cells in the DRAM. The DRAM may be configured to operate at an increased refresh interval, thereby reducing DRAM refresh energy but causing a predictable portion of the memory cells in the DRAM to leak electrical energy too quickly to retain data. The DRAM is further configured with a selected number of spare memory cells for replacing the “leaky” memory cells, so that operation of the DRAM at the increased refresh interval may result in little or no reduction in capacity of the DRAM.
