A decoding apparatus and method of a terminal in a wireless communication system are provided. A carrier to interference and noise ratio (CINR) estimator estimates a CINR value of a received signal, and a controller generates a modulation and coding scheme (MCS) level candidate set satisfying the estimated CINR value and a target packet error rate (PER) based on a look-up table. A decoder switch determines if an MCS level of a burst is included in the MCS level candidate set when the burst having no connection identifier (CID) information exists in a corresponding frame, and determines to decode the corresponding burst if the MCS level of the burst is included in the MCS level candidate set and to discard the burst otherwise.

A logical structure retaining device retains a corresponding relationship between heading information and table data, such as attributes used to search a data base and data obtained by the search. A table form retaining device retains one or plural sets of parameters that determine respective table forms. The parameters can be edited by a table form editing device. A table generating device generates a table by receiving information including the corresponding relationship between the heading information and the table data, referring to the parameters of the table form retaining device, calling, if necessary, a parameter designating device to input parameter values, and generating row heading items, column heading items and data items based on the above information.

Both of a user side and a protect side such as a programmer of an application programmer need not handle a large number of inherent information such as authentication keys. An access ticket generation device generates an access ticket from user unique identifying information and access rights authentication feature information. As unique security characteristic information, there is used a secret key of an elliptic curve encryption or an ElGamal encryption. A proof data generation device receives the access ticket, converts authentication data received from a proof data verification device into proof data by use of the access ticket and the user unique identifying information, and returns the resultant proof data to the proof data verification device. The proof data generation device or the proof data verification device decrypts the above-mentioned encryption. The proof data verification device verifies the access rights as correct access only when a combination of an access ticket and user unique identifying information used in the proof data generation device is correct.

A user operates a user interface to select a rule for executing the process of a work flow, which is stored in a personal data base or a shared data base, and sends the conditional part of the selected rule as the goal to a query portion. Then, the query portion successively executes the process of the work flow through the computation by the SLD contradiction. When the goal fails in the execution by the computation, the failure goal is transferred as a tapple to the tapple space. The tapple is solved by another query portion, and the result of executing the tapple is returned to the tapple space. If a rule for executing the tapple is not found, the task is processed by man or a user and the result of the processing is entered into the system. In answer to this, the system interprets that the task has been proved to be true, and continues the execution of the work flow process.

A table allocating apparatus for producing a layout of a table. In the apparatus, both of a linear equation for representing a column width of a table or a row height thereof by employing a parameter, and a section constraint condition corresponding to a combination of conditions for satisfying the parameter in order that a height or a width of a rectangle becomes constant when each of texts arranged in a table item column is allocated are set, then a layout evaluation formula expressed by the linear equation with employment of the parameter and indicative of better states of a layout for each of the section constraint conditions is calculated. Further, such a linear programming problem that the section constraint condition is used as a restriction condition and the layout evaluation formula corresponding to each of the section constraint conditions is used as an objective function is solved, thereby obtaining a set of an optimum layout evaluation value and a parameter corresponding to the optimum layout evaluation value, or an infeasible solution of the problem, and when the set of the optimum layout evaluation value and the parameter corresponding thereto is acquired, a set of the optimum layout evaluation value and the parameter corresponding thereto based on the acquired result among all of the linear programming problems are retrieved, whereby a table layout is determined based upon the set of the optimum layout evaluation value and the parameter corresponding thereto.
