A computer program, method and computer apparatus for calculating the total importance of an electronic document on the basis of (i) a plurality of electronic documents chained to each other in a relation of referencing and being referenced, from a start electronic document which is not referenced by other electronic documents to a terminal electronic document which does not reference other documents, (ii) the information on relation of referencing and being referenced, (iii) an important phrase, and (iv) a response coefficient determining phrase such as an agreeing phrase, a disagreeing phrase, and a topic change phrase, (i) through (iv) being stored in a storage device.

Computer apparatus, computer program and method, for calculating importance of electronic document on computer network, based on comments on electronic document included in another electronic document associated with former electronic document

A method and system for determining a variable compensation amount according to the degree of achievement by avoiding stop at the stage where value brought about to a client by a solution is qualitatively evaluated, avoiding compensation calculation from being performed by accumulation of cost such as labor cost, and quantitatively estimating the effect from the viewpoint of a set KPI in consideration of risk to achievement of the KPI. There is provided a system for supporting advance evaluation of a service for improving business, comprising: input means for accepting selection of an index indicating the degree of improvement of the business and accepting setting of multiple future scenarios which influences success/failure of the improvement of the business; storage means for storing the index and the multiple scenarios; and calculation means for calculating a primary estimate value of the index in the case of occurrence of each scenario and calculating a secondary estimate value based on the primary estimate value and a primary risk corresponding to the primary estimate value.

Computer program for supporting evaluation of a service

An apparatus for evaluating organization efficiency, a method for evaluation service of organization efficiency, an apparatus for generating communication frequencies, a method for generating communication frequencies, and programs and recording media of the same, quantitatively evaluate efficiency of an organization structure. The present invention provides an apparatus for evaluating organization efficiency having communication frequencies among departments obtaining unit for obtaining communication frequencies among departments, the frequency being frequencies of information interchanges among departments within an organization; a group definition data obtaining unit for obtaining group definition data, the data defining a group including more than one department within an organization; communication frequencies among groups calculation unit for calculating communication frequencies among groups for groups interchanging information, on the basis of communication frequencies among departments; and an organization efficiency calculation unit for calculating efficiency of an organization structure defined by group definition data, on the basis of the communication frequencies among groups.

Collaborative organization analysis

A system and method which dynamically changes the load balance of assigned loads for each group in a sequence of processes from a first stage to an n-th stage in a computer having a plurality of processors, wherein the plurality of processors are grouped into at least two groups, comprises the steps of: detecting a change in a characteristic value in a queue for transferring a processing result between the groups; and changing the assignment of assigned processes for each group based on the change in the characteristic value. A characteristic value stored in a queue represents a value related to work load, and a queue seldom becomes full or empty if the load balance is changed referring to this characteristic value.

Method for dynamically changing load balance and computer

The present invention enables image information of high resolution to be transferred via a transmission line with limited band width using a simple configuration. In transferring image information between a main body of a computer and a display, a dither matrix is used to update images stored in the display. That is, a plurality of blocks whose size is of a predetermined dither matrix are defined in an image, and information of each pixel in each block is transferred to the display in order of a value of a corresponding element in the dither matrix. Transfer of unchanged pixel data can be omitted. In addition, in transferring image information between the main body of the computer and the display, image information stored in the computer is divided into a plurality of blocks, for each of which the number of changed pixels or the number of writings to pixels in the block is calculated so that image information in blocks which exceed a predetermined number is transferred to the display block by block.

A computer graphics apparatus connects a texture coordinate generator with fragment generators via a command bus. The generator is connected to a texture data bus through a texture memory cluster which comprises an address generator connected to a texture coordinate bus, a filter, and eight memories. In addition, the generator is connected to the texture data bus through a plurality of texture memory clusters. The texture data bus is connected to a plurality of drawing processors to which a plurality of frame memories are connected in correspondence. This configuration performs texture mapping through effective utilization of the texture memory clusters.

Method and apparatus for performing texture mapping

A texture memory for storing color information of a surface of an object and displacement information of the object, wherein the information is prepared in advance; reading means for reading out the color information of the surface of the object and the displacement information of the object necessary for drawing the object from the texture memory in response to receiving a command instructing to draw the object stored in the texture memory according to a size and a position, if necessary, color information and displacement information specified by the command; size modifying means for expanding or reducing and/or modifying the read color information of the surface of the object and the read displacement information of the object by using the color information and the displacement information, and if specified, using the specified displacement information if specified so as to correspond to the size and the displacement specified in the command; color modifying means for modifying the color information processed by the size modifying means based on the specified color information if specified; and hidden surface processing means for performing a hidden surface removal for the drawing surface of the object by using the color information of the surface of the object and the displacement information of the object from the size modifying means or the color modifying means and by the position specified in the command. This enables a rapid measure to be taken against the case of drawing a great number of spheres, pipes or the like.
