A monetary risk prediction apparatus according to an embodiment includes: a predictive model recording unit that records a predictive model to predict time-series data showing a future asset amount of a user; and prediction means for receiving evaluation data that is time-series data including an asset amount and a numeric value showing a health condition of the user, inputting the evaluation data to the predictive model recorded on the predictive model recording unit, and outputting the time-series data showing the future asset amount of the user predicted by the predictive model according to the input.

Forecasting device, method, and program for predicting user financial assets and health

The purpose of the present invention is to accurately identify an appearance position of a desired waveform pattern. A signal feature extraction apparatus extracts a feature peak value of a waveform pattern from an output signal of a feature extraction filter that extracts a waveform pattern of an input signal. A local maximum value detection partstores a time index and a value of the output signal when an absolute value of the output signal is equal to or more than a predetermined threshold value and takes a local maximum value. A feature peak value selection partselects a feature peak value on the basis of a difference between a time interval between the stored time index and a time index of a feature peak value selected immediately before and an average time interval at which the feature peak value can occur, and a difference between a logarithmic amplitude and phase of the output signal corresponding to the stored time index and an average logarithmic amplitude and average phase that the feature peak value can take.

The purpose of the present invention is to reduce leakage of an output signal between band-pass filters and in the time axis direction. A signal input partvectorizes an input signal x(n). An extended impulse response matrix generation partgenerates an extended impulse response matrix Hin which impulse response vectors using impulse response sequences of band-pass filters as elements are extended in the time axis direction. An expansion coefficient calculation partcalculates an expansion coefficient vector {circumflex over (&#x2003;)}y(n) using an input signal vectorsx(n) and the extended impulse response matrix H. A signal output partoutputs at least one of expansion coefficients corresponding to a center vector of the extended impulse response matrix Hof the expansion coefficient vector {circumflex over (&#x2003;)}y(n).

A system management method is disclosed for associating a process object and a process with each node in a tree structure, and operating each node based on the tree structure so as to manage the process object and the process, including: registering a registered user that performs operations for a general node corresponding to the process object or for a function node corresponding to the process; setting the function node as a child node of the general node corresponding to the process object for which the process corresponding to the function node should be performed, and setting the general node as a parent node of the function node; setting registered user operation authority for each registered user; and, when execution of the process corresponding to the function node is requested by the registered user, causing the function node to execute the process only when the process is permitted by the registered user operation authority, of the registered user requesting the process, set in the general node that is a parent node of the function node.

A database access control apparatus generates and stores an access key based on a user ID of a user apparatus. Then, the database access control apparatus sends the access key to the user apparatus with an address of a proxy process server apparatus. The user apparatus sends the access key to the proxy process server apparatus when making a database access request, and the proxy process server apparatus sends the access key to the database access control apparatus when making a database process request. When receiving the database process request, the database access control apparatus determines whether an access key same as the access key received from the proxy process server apparatus is stored in the database access control apparatus, and accesses the database only if having the access key.
