Abstract: The invention provides a mechanism for a transaction coordinator to indicate to a transaction participant that it supports a heuristic outcome, where a course of action has occurred which means that the transaction participant is unable to honor a transactional prior commitment to the transaction coordinator. The mechanism is such that a transaction participant that is incapable of communicating a heuristic outcome may ignore any such indication. A transaction participant may be incapable because it does not understand the concept of a heuristic outcome at all or because it does not have the ability to inform the transaction coordinator that a heuristic outcome has occurred.

Abstract: A method, apparatus and computer program are disclosed for modifying an application comprising a plurality of modules. A user is presented with a list of modules. The user is able to specify input regarding any permitted version modifications for the modules listed. It is then determined whether the requested modifications are possible with one or more failure messages being output when any of the requested modifications are not possible. At least one of the failure messages is used to enable modification of the initial input provided by the user. In one embodiment, information is provided to the user based on one or more failure messages in order to enable the user to modify their choices. In another embodiment, the initial input is automatically modified. A permitted version modification may be, for example, a version upgrade, a version downgrade, and an indication that there is no preference.

Abstract: Curable and cured epoxy-based coating compositions are described. The curable coating compositions are typically two-part epoxy-based formulations. The cured coating composition can be used in various applications such as those in which the curable coating composition is applied to either a clean surface or to a surface contaminated with a hydrocarbon-containing material. The cured coating composition typically bonds effectively to the substrate even in the presence of a hydrocarbon-containing material.

Abstract: Approaches described in this disclosure are generally directed to methods and devices for delaying a write turn-on of a memory device. A write control signal from a memory controller to a preamplifier of a storage device is asserted. A warm-up interval of write drivers of the preamplifier is initiated, the warm-up interval having a duration of predetermined length. Data is transmitted to the write drivers during the warm-up interval.

Abstract: A method of forming unique, private, personal, virtual social networks on a social network system that includes a database storing data relating to corresponding user entities. The method includes: a first user entity sending an invitation to a second user entity, recording in the database the second user entity as a direct contact of the first user entity and determining that third user entities, directly connected to the second user entity, are indirect contacts. A unique, personal, social network formed from direct and indirect contacts is thereby created for each user entity. Each user entity is able to control privacy of its data with respect to other user entities depending on the connection factor to that other entity and/or that other entity's attributes. Each user entity is able to take the role of provider or participant in applications where the provider provides an item or service to the participant.

Abstract: A satellite system for observing space objects includes two or more satellites positioned in an Earth orbit and configured to observe objects in various orbits including those viewed (i) against the Earth's background; (ii) against a sunlit Earth background; and (iii) against a space background. An electromagnetic sensor may be provided on at least one of the satellites that is responsive to electromagnetic radiation having a wavelength that discriminates against substantial reflection of electromagnetic radiation from the Earth's atmosphere to observe the space object. A method of observing a space object using a satellite system is also disclosed.

Abstract: A method of handling a message in a messaging system is provided. The messaging system comprises a message source, a message receiver and a message service. The message service is intermediate of the message source and message receiver, wherein a compensation component is established at the message source.

Abstract: A first instance of the application can be executed. While the first instance of the application is executing, at least one request to access the application (first access request) can be processed by directing the first access request to the first instance of the application. Further, a request to update the application can be received. Responsive to the request to update the application, at least one new application component corresponding to the update request can be installed. A second instance of the application can be executed. The second instance can include at least one new application component.

Abstract: A mechanism is provided for deciding whether to install a first application within one of a plurality of candidate environments. An environment comprising one or more other applications. The first application and a candidate environment are analysed to determine whether there is the potential for the first application to interact in an unintended manner with an application in the candidate environment. If there is no such potential, then the environment is identified as a suitable environment into which to install the first application. An unintended interaction is when a rule would be broken by an interaction between the first application and an application in the candidate environment.

Abstract: The present invention provides a method, apparatus and computer program product which enables a target service to provide operations which behave, on a per operation basis, in a way appropriate to the type of client that requested the operation to be performed. As a result the target service can provide operations which behave differently for different clients. Further the client can obtain details of the behavior characteristics of the operations, according to its type, at runtime and act appropriately in the event of the request being timed out or resulting in a communication failure. For example, the client middleware can take action to re-issue a timed out request if the behavior characteristic for that operation indicates that multiple invocations of the operation will yield the same result.

Abstract: A communication system and method is provided that modifies a signal for transmission at a transmitter to reduce peaks associated with the signal. The signal can be modified employing signal shaping, signal clipping, signal decomposition or other techniques to remove peaks associated with the signal. The communication system can also correct the modified signal at a receiver to reconstruct the originally wanted signal.

Abstract: A method and system for immediate failure checking for lost message processing comprises receiving a first message of a web-service transaction comprising first message sequence information at a computing device in a transaction environment of a target web service, storing a first record of the first message within the computing device, receiving a subsequent message comprising corresponding message sequence information at the computing device, storing a second record of the subsequent message within the computing device, comparing the first message sequence information with the subsequent message sequence information using the computing device, identifying a transaction error using the computing device, if the subsequent message is not an initial message in a sequence of messages based on the comparing, reporting the transaction error from the computing device, and aborting processing of the web-service transaction if the transaction error has occurred, using the computing device.

Abstract: An acrylic polymeric composition comprising a melt blend of a thermoplastic high molecular weight acrylic material (HMWA) and a thermoplastic low molecular weight acrylic material (LMWA) is described. At least 70% w/w of the HMWA and the LMWA comprises an alkyl (alk)acrylate (co)polymer.
