Big data analytics is critical in modern operations management (OM). In this study, we first explore the existing big data‐related analytics techniques, and identify their strengths, weaknesses as well as major functionalities. We then discuss various big data analytics strategies to overcome the respective computational and data challenges. After that, we examine the literature and reveal how different types of big data methods (techniques, strategies, and architectures) can be applied to different OM topical areas, namely forecasting, inventory management, revenue management and marketing, transportation management, supply chain management, and risk analysis. We also investigate via case studies the real‐world applications of big data analytics in top branded enterprises. Finally, we conclude the study with a discussion of future research.

Big Data Analytics in Operations Management

System, method, and tangible computer-readable storage media are disclosed for providing a brokering service for compute resources The method includes, at a brokering service, polling a group of separately administered compute environments to identify resource capabilities and information, each compute resource environment including the group of managed nodes for processing workload, receiving a request for compute resources at the brokering service system, the request for compute resources being associated with a service level agreement (SLA) and based on the resource capabilities across the group of compute resource environments, selecting compute resources in one or more of the group of compute resource environments The brokering service system receives workload associated with the request and communicates the workload to the selected resources for processing The brokering services system can aggregate resources for multiple cloud service providers and act as an advocate for or a guarantor of the SLA associated with the workload

System and method of brokering cloud computing resources

In one embodiment, a device includes a device body that includes a touch-sensitive display and a processor. The device also includes a band coupled to the device body and an optical sensor in or on the band. The optical sensor faces outward from the band and captures images. The processor communicates with the optical sensor to process captured images.

Wearable electronic device

In one embodiment, an apparatus includes one or more processors and a memory coupled to the processors that includes instructions executable by the processors. When executing the instructions, the processors present on a display of the apparatus a first screen of a graphical user interface. The first screen includes one or more first elements. The processors receive user input indicating a transition in the graphical user interface and, in response to the user input, transition from the first screen to a second screen of the graphical user interface and apply one or more visual transition effects to the transition. The second screen includes one or more second elements.

An on-demand compute environment comprises a plurality of nodes within an on-demand compute environment available for provisioning and a slave management module operating on a dedicated node within the on-demand compute environment, wherein upon instructions from a master management module at a local compute environment, the slave management module modifies at least one node of the plurality of nodes.

On-demand compute environment

A method and system for gathering enriched web server activity data in a global communications network in which requested information files are cached at a plurality of network devices. With the prevalence of web caching on the Internet, the origin web servers do not serve the majority of requests for web site content. A single pixel clear Graphics Image Format (GIF) request is added to the HyperText Markup Language (HTML) source file for a web page. Appended to the GIF request is a Common Gateway Interface (CGI) string of data that contains enhanced web activity data information, including the number of images ( hits') that have to be retrieved by a client browser to build the web page, and the referring identifier that resulted in access to the web page. The single pixel clear GIF request is not cacheable and results in the request being transmitted to the origin web server when the client browser interprets the HTML file. The enriched data is stored in log files at the origin web server to accumulate an accurate number of hits on the web page.

Approaches are provided for answering an inquiry of a cognitive distributed network. An approach includes receiving the inquiry at the cognitive distributed network. The approach further includes determining a classification for the inquiry based on natural language of the inquiry. The approach further includes classifying the inquiry as a single question class. The approach further includes determining, by at least one computing device, a type of introspection to be used by the cognitive distributed network on the inquiry. The approach further includes generating an answer to the inquiry based on the determined type of introspection.

Cognitive distributed network

System, method and program for making same data available from different file systems to clients. The data is transferred to each of the file systems. Respective time periods required to rename the data in the file systems from a first name to a second name are estimated. The data with the first name is not available to the clients. The data with the second name is available to the clients. Renaming of the data in the file systems from the first name to the second name is scheduled. The scheduling is based at least in part on the estimated respective time periods to rename the data in the file systems. Preferably, the scheduling is timed to result in completion of the renaming of the data in all of the file systems at approximately a same time. Preferably, one of the time periods to rename the data in the file systems is based at least in part on a time period to transfer the data to a server associated with the file system and a wait time within the server to schedule the renaming.

System, method and program to synchronize files in distributed computer system

In a method for authenticating a current user of a near field communication (NFC) device, a profile for an authorized user of the NFC device is established based on data received from one or more sensors of the NFC device over a first period of time. Responsive to a request for a payment transaction, a profile for the current user of the NFC device is established based on data received from the one or more sensors over a second period of time after the first period of time. The profile for the current user is compared with the profile for the authorized user. A determination is made as to whether one or more values in the profile for the current user are within a range of one or more values in the profile for the authorized user at a confidence level.

Authentication for transactions using near field communication

A method, system and program product for collecting web metric data is disclosed. The method includes inserting a script at the top of each web page to be metered, sending a web page request to a web server for a web page, loading the web page while executing the script inserted within the web page for collecting web usage data without substantially increasing web page load time. The method further includes establishing an asynchronous connection to a metric server chosen for sending the web usage data collected and transmitting to the metric server the web usage data collected as part of a record request using a method such that the record request is not cached at an intermediate proxy. The method further includes contacting an alternate metric server if the metric server chosen is not available or cannot record the web usage data.
