Abstract: Data usage of a messaging application is mitigated based on a location of the application on the display screen or a mode of a device. If the location of the application is in the foreground of the display, presence update information of a contact is periodically received or requested. If the application is in the background of the display longer than a predetermined interval, the presence update information of the contact is stopped. In some embodiments, if the device is in an OFF or a SUSPEND mode, contact presence updates are not received. When the device is in an ON mode or state, the presence updates are received or requested from a server or presence agent.

Abstract: A distributed processing system includes plural nodes each provided with a processor and communicably connected to each other. A task information obtaining unit obtains antecedent dependency between tasks. A node information obtaining unit obtains a time constraint imposed on the tasks. A start time computing unit computes an absolute earliest start time at which a task can be started and an absolute latest start time allowed in order to complete the task within the time constraint, by referring to the time constraint. A node selector selects a destination node to which a target task not yet allocated to a node should be allocated, by referring to the absolute earliest start time and the absolute latest start time. A task placement unit causes the task to be executed in the selected node.

Abstract: A solution is provided for accessing a shared resource in a data processing system (such as a server of a DAM application) by a plurality of exploiter entities (such as clients). A corresponding method starts with the step of monitoring an activity of each enabled entity being granted an access to the shared resource. The access granted to each enabled entity is released in response to the reaching of a first threshold (such as a time-out period) by an inactivity indicator, which is indicative of the non-activity of the enabled entity (such as an idle time). The method continues by detecting a critical condition of the shared resource (such as after reaching a maximum number of concurrent accesses). The access granted to an eligible enabled entity (or more) is released in response to the critical condition; the inactivity indicator of each eligible enabled entity reaches a second threshold preceding the first threshold (such as a grant period lower than the time-out period).

Abstract: An image processing apparatus which can be readily used by an authenticated user without laborsome setting even if the user uses the image processing apparatus for the first time through an authentication server. A user is authenticated with an authentication server connected to an image processing apparatus via a network. User unique setting information for the authenticated user is set, and the user unique setting information for each user is stored in user information storing areas. Initial setting information of initial setting of the image processing apparatus is stored in an initial setting information storing area. When the authenticated user uses the image processing apparatus for the first time, duplicate copy of the initial setting information stored in the initial setting information storing area is stored as the user unique setting information in the user information storing areas.

Abstract: A network device and method are directed towards detecting and blocking image spam within a message by performing statistical analysis on differences in edge pixel distribution patterns. An image spam detection component receives a message with an image attachment. Physical characteristics of the image are examined to determine whether the image is a candidate for further analysis. If so, then the image may be converted to a grayscale image, and then performing edge detection, followed by the elimination of non-maxima and thresholding of weak edges. Edge pixels and then employed to determine a normalized pixel density distribution (PDD). Various statistical analyses are applied to the resulting normalized PDD to determine a likelihood that the image is spam. A signature based exemption may be applied to images improperly identified as spam, based on trusted user feedback.

Abstract: To suppress a server processing load and a network load in a sensor network which accommodates a great number of mobile sensor nodes. Among a plurality of distributed data processing servers (DDS) for managing data of sensor nodes, a distributed data processing server (DDS) that is a home server to hold data of a mobile sensor node is set for each sensor node by a directory server (DRS). At each distributed data processing server (DDS), upon reception of the data from the sensor node, identification process is executed as to whether the data is sensor data to be managed by itself or another distributed data processing server. If a result of the identification is the sensor data to be managed by another distributed data processing server, the data is transferred to the distributed data processing server (DDS-1), which corresponds to the home server of the sensor data, based on setting of the directory server (DRS).

Abstract: A method for assigning a global address to a node in an ad-hoc network is provided. A joining node to the ad-hoc network generates a local address using its MAC address. The joining node inquires of its one-hop nodes about whether they occupy a local address that is the same as the generated local address. When the joining node is informed that there are no nodes occupying the same local address, it generates a global address using the generated local address and a global prefix provided from neighbor nodes. The joining node inquires of an Internet gateway about whether the generated global address is currently used. When the joining node is informed that there are no nodes currently using the same global address, the joining node is assigned the generated global address. Further, the joining node and the Internet gateway communicate messages via a relay node using a tunneling.
