    摘要： To provide a waveguide type wavelength domain optical switch which makes it possible to use a cheap lens, makes it possible to correct aberration of the demultiplexed wavelengths produced in a plurality of waveguide type demultiplexing circuits, a wavelength domain optical switch is provided with: an integrated element formed by laminating three or more waveguide type demultiplexing circuits; a first lens for collecting light emitted from the integrated element; a polarization separation element for separating light emitted from the first lens into X polarization and Y polarization and emitting the X polarization and the Y polarization at different angles; a second lens for collecting the X polarization and the Y polarization; a first reflective optical phase modulator for reflecting the collected X polarization and Y polarization at any angles; a ½-wavelength plate disposed between the second lens and the first reflective optical phase modulator in order to make polarization directions of the X polarization and the Y polarization identical; and a second reflective optical phase modulator for inputting light from the first reflective optical phase modulator into one of the waveguide type demultiplexing circuits.

    摘要： A technique for enhancing the execution efficiency of simulation of a hybrid system. A continuous system simulator receives a request for evaluation of an event generating conditional expression for an event to be processed by a discrete system simulator, from the discrete system simulator. The event generating conditional expression is evaluated by referring to the value of a first variable describing a continuous system. Until evaluation of the event generating conditional expression indicates true, the continuous system simulator repeats simulation of advancing the current time by a step time interval and evaluation of the event generating conditional expression. When evaluation of the event generating conditional expression indicates true, the continuous system simulator sends current time data and the value of a second variable describing the continuous system which is referred to by the discrete simulator, to the discrete simulator.

    摘要： A system, method and computer program for generating a sequence diagram that specifies processing among modules included in source code. First, a source code is acquired and then analyzed to generate a log acquisition code for acquiring an execution log. Then, a program including the generated log acquisition code is executed to acquire execution log information on the execution of the program. On the basis of the acquired execution log information, automaton information on states and transitions among the states is extracted, and then the extracted automaton information is converted into sequence diagram component information on components constituting a sequence diagram. Thereafter, a sequence diagram is generated based on the converted sequence diagram component information.
