A system and method is described for effective management of a User Interface (UI) of a wireless device by implementing direct mapping between the application data domain and UI screens and controls. The device has an intelligent wireless device runtime environment (Device Runtime) that provides a set of basic services to manage the wireless application, including a series of linked screen and data component definitions, and their interactions can simplify the development effort and reduce resource allocation. The data domain for this category of applications is defined using the atomic data component definitions. The communication between a device user interface and data components is defined using atomic screen component definitions. Both screen and data component definitions are described in metadata using a structured definition language such as XML. The relationships between the screen and data component definitions are embedded in the XML definitions in the form of screen/data mappings. Typically, rendered screens for display are derived from some underlying data component and screens controls affected by user events impact the current state (or data representation) of the application Changes to the application domain data are automatically synchronized with the user interface, and user-entered data is automatically reflected in the application domain data. The primary mechanism behind this synchronization is the mapping of screens and data. This mechanism enables creation of dynamic and interactive screens. All changes to the data component can be immediately reflected on the screen and vice versa. This model allows building effective wireless applications based on server-to-device notifications. The data updates asynchronously pushed from the server are instantaneously reflected at the UI screen.

It is desirable to drive down the complexity involved in developing the wireless application by reducing the need to do any explicit coding, as well as reducing device resources utilized by the application when provisioned. Having an intelligent wireless device runtime environment (Device Runtime) that provides a set of basic services to manage the wireless application as a series if application components, and their interactions, can simplify the development effort and reduce resource allocation. The wireless application is described as a set of components. The data domain for this category of applications is defined using atomic data components. The communication between the device and a server is defined using atomic message components. Both message and data components are described in metadata using a structured definition language such as XML. The relationships between the message and data components are embedded in the XML definitions in the form of message/data mappings. Typically, outgoing messages are derived from some underlying data component and incoming messages affect the current state (or data representation) of the application. It is therefore apparent that the metadata defined mapping relationship is preferable between the expression of data and message components.

A system and method that modifies the behavior of the IEEE 802.1D STP standard to thereby decouple the one data domain from the one control domain involves managing multiple spanning tree protocol (STP) instances in a virtual local area network (VLAN). The method includes the step of assigning a unique set of ports within the VLAN to each of the multiple STP instances. Then, each of the multiple STP instances are managed to keep each of the multiple STP instances separate. Finally, when a topology change is detected in one of the multiple STP instances, entries that have been learned on the unique set of ports assigned to the STP protocol instance where the topology change is detected are fast-aged or transitioned from one state to another.

A system and associated method for evaluating cross-domain clusterability upon a target domain and a source domain. The cross-domain clusterability is calculated as a linear combination of a target clusterability and a source-target pair matchability, by use of a trade-off parameter that determines relative contribution of the target clusterability and the source-target pair matchability. The target clusterability quantifies how clusterable the target domain is. The source-target pair matchability is calculated as an average of a target-side matchability and a source-side matchability, which quantifies how well target centroids of the target domain are aligned with the source centroids and how well source centroids of the source domain are aligned with the target centroids, respectively.

Three or more materials are advantageously separated from dual energy data by using a material separation technique. To effectively separate material clusters, a density plot is introduced to automatically render cluster separations. Initially, the projection data optionally undergo data-domain dual energy decomposition. Then, the image data is plotted in a vector plot whose axes are the low HU values and the high HU values. For a given data point in the vector plot, a number of data points is counted within in a region of interest surrounding the given data point to generate a density plot where each point now represents a density level surrounding the data point. Thus, clustering of a certain material is visualized by a predetermined color assignment scheme. Furthermore, special image processing methods such as Gaussian decomposition are used to improve the accuracy of material separation. In addition, the HSL color model may be used for better visualization and to bring a new dimension in material separation display.

A computer database for storing information in tuple form wherein each tuple comprises fields with corresponding fields in the tuples constituting a column, generates for each data domain a domain dictionary which matches each distinct data value in that domain with a corresponding distinct token, and stores each domain dictionary. A tokenised store for each data field column is created. All of the tokens for a domain are initially of the same size being substantially the minimum size necessary to provide the required plurality of distinct tokens for initialize size of that domain.
