摘要:
An inundation simulation program and device using the same for displaying a map, receiving input from a user indicating a starting point and an ending point in a bank breakage section on the map, and displaying on the map a line connecting the starting point and the ending point. Further, the computer program and device calculates a direction of a flow quantity in the bank breakage section by calculating a normal line to the side of the inside area of the bank at the input band breakage section and making the bank breakage section discrete in the calculation grids of the inundation simulation.

A radio terminal corresponding to a first radio terminal associated with a second radio terminal comprises following units. A first receiving unit receives a first request issued from the second radio terminal. An establishing unit establishes, in response to the first request, a radio link with respect to the second radio terminal. A setting unit sets, on the radio link, a connection with the second radio terminal. A detecting unit detects an event in association with the second radio terminal. A first transmitting unit transmits, to the second radio terminal via the connection, a first request message representing that first service information concerning the second radio terminal should be transmitted to the first radio terminal, when the detecting unit detects the event.
摘要:
A long object management system for managing the history of the attribute data as well as the shape data constituting the temporal information of pipeline facilities, in which the future prediction is conducted by acquiring and managing the temporal information. The system comprises a unit for managing the time change data by the difference management of the pipeline shape and attribute data, and a unit for retrieving the time change data managed by difference, correcting the position using the result of retrieval and setting the correspondence between the time change data by correcting the data position.
摘要:
A figure management system in which plural kinds of figures concerning the same part to be managed are modified. The figure management system includes a figure DB for storing data of figures including topological figures, an attribute DB for storing object attribute data, input and output devices, and a computer for managing figure and object attribute data. An ID code common to features indicating the same object is assigned. On input of a new figure, feature-attribute matching is performed between a feature having no ID code on the new figure and existent object attribute data. If any inconsistency is found the feature is indicated as a discrepant feature or a renewed feature.

A communication network construction method comprises the steps of grouping the communication devices belonging to a communication network into one or a plurality of communication groups. In a selection step, one or a plurality of representative devices are selected in each communication group formed in the grouping step. In a communication step, each communication device communicates directly with the communication devices belonging to the same group, and communicates with the communication devices belonging to a different group by first transmitting data to the representative device of the same communication group and then causing the representative device to transfer a part or the whole of the data to the representative device of the different communication group.

An image displaying method and apparatus for simultaneously displaying an enlargement target of an entire original image and its enlarged image on a display screen by automatically disposing the enlarged image. The image displaying apparatus includes display for displaying an enlarged image of part of the entire original image including characters, patterns, etc. in a relation superposed on the entire original image, input apparatus for pointing to specify the enlargement target in the entire original image, and automatic disposing apparatus for preferentially specifying and computing the values of the area of the enlargement target region, the area of the enlarged image display region and the enlargement ratio so as to maximize one of these values and disposing the enlarged image on the basis of the result of computation. Further, in order that the enlarged image is easily visible, the enlargement target region and the enlarged image display region are disposed and displayed on the display screen so that a peripheral region adjoining the enlargement target region is displayed between these two regions.

A traffic supervisory method for supervising a group of packets generated in a terminal according to an assigned traffic characteristic in which the maximum number of packets generated within a regular period time T is set at N comprises respectively counting the number of packets which are generated within regular time periods .alpha.i.multidot.T ({.alpha.i.vertline.1.ltoreq.i.ltoreq.M, 1.ltoreq..alpha.1 . . . >.beta..sub.M =0}) within at least one regular interval of time .alpha.i.multidot.T.
摘要:
A graphics display image is displayed on a display, the graphics display image being formed by a plurality of graphics display image components, at least some of which have to be edited. The graphics display image components may be generated from data obtained e.g. from optical reading of a hard-copy of a map, circuit diagram, or design drawing by a suitable optical reader. The graphics display image components which are to be edited are displayed with a different visual appearance from any components which do not have to be edited, e.g. by highlighting the components to be edited. As the editing of each components is completed, its visual appearance is changed, e.g. the highlighting cancelled, so the operator has an immediate visual indication of the components which have not yet been edited. In this way, complete editing can be ensured. Different editing operations are possible including creating a cursor corresponding to the component to be edited, adjusting that cursor to correspond to the location, size and orientation of the component to be edited, and replacing the component with the cursor image.
摘要:
A packet network in which the qualities of service can be maintained for different communications of different classes of requirement for quality of service, regardless of types of calls and data. In this packet network, a communication resource is subdivided into sub-resources which are to be allocated to communications classified into communication classes, where an amount of communications within each sub-resource is controlled independently to satisfy a required quality of service. Also, first type of calls for which a ratio of a maxium transfer speed of each call with respect to a transfer speed of multiplexed line of the packet network is greater than a predetermined threshold value, and second type of calls which are not the first type of calls are distinguished, and a priority control to favor the first type of calls over the second type of calls is performed.
摘要:
A three-dimensional (3D) map display system for outputting display information on a 3D map includes: a processor for performing arithmetic processing; and a memory connected to the processor. The memory stores 3D map vector data for each of partitioned areas determined in advance according to coordinates and a real landscape photograph texture image to be attached to the 3D map vector data. The processor determines whether to display each surface constituting a 3D figure included in the 3D map vector data; stores display object management data which includes a result of the determination as to whether to display the surface, in the memory; and refers to the display object management data stored in the memory to determine that only a surface that faces a view line direction is to be displayed, and that a surface that does not face the view line direction is not to be displayed.
