Abstract: Techniques for enhancing the security of a communication device when conducting a transaction using the communication device may include using a limited-use key (LUK) to generate a transaction cryptogram, and transmitting a token instead of a real account identifier and the transaction cryptogram to an access device to conduct the transaction. The token and the transaction cryptogram can be transmitted to a magnetic stripe reader by generating an emulated magnetic signal. The LUK may be associated with a set of one or more limited-use thresholds that limits usage of the LUK, and the transaction can be authorized based on at least whether usage of the LUK has exceeded the set of one or more limited-use thresholds.

Abstract: This disclosure relates generally to fleet route optimization. Conventional methods for fleet route optimization have limited capability in managing and controlling transport of material from geographically spread out suppliers to the door-step of the customer in an efficient manner in real-time. The disclosed method includes optimization at two levels. At the first level and initial optimized route is obtained for the fleet by clustering the target locations into multiple clusters and obtaining heuristic on each cluster by using a weightage matrix. The initial set of optimized routes are examined in real time, and based on said examination, the routes are optimized (second level optimization) to provide a final set of optimized routes. The disclosed method and system thus facilitate in creating routes dynamically, monitor it through the application, and dynamically change and/or alter the routes based on new order and/or execution challenges.

Abstract: A cross sectional representation of a geological surface is displayed on a display screen. A segment of the cross-sectional representation is edited, and a pseudo log of formation properties based on the edited segment is displayed on the display screen. A determination is made whether formation properties associated with the pseudo log match actual formation properties measured during drilling of a well and a signal is output indicative of the match. A drill operator may use a structural model determined based on the edited geological surface to drill for hydrocarbons in the formation.

Abstract: Aspects and features of this disclosure provide a high-availability storage platform employing multiple redundant sites. Replication to multiple sites can begin upon receiving content and can be completed quickly, in part through the use of a small and efficient file that can be sent to storage sites. The file enables each storage site to efficiently build appropriate entries in a reference registry for storing and indexing the content. In some examples, a registration request including the content is received and the content is stored in an instance of the centralized storage system at an initial storage site. The aforementioned file is transmitted to additional storage sites to cause the content to be stored in additional instances of the centralized storage system. The file can also be accessed at the additional storage sites to update instances of the reference registry.
