A contained resonant cavity. The contained resonant cavity includes a first surface and a second surface that are partially transmissive and partially reflective, One or more reflective sidewall, are positioned between the first surface and the second surface. In a specific embodiment, the first surface and the second surface are substantially parallel and represent input and output surfaces, respectively, of the contained resonant cavity. The one or more sidewalls are approximately perpendicular to the first surface and the second surface and include a first sidewall having a first substantially reflective planar surface that faces a second substantially reflective planar surface of the second sidewall. A third sidewall and a fourth sidewall have fourth and fifth substantially reflective Lacing sidewalls, respectively. In an illustrative embodiment, the one or more sidewalls include plural reflective sidewall, arranged perpendicularly between the first surface and the second surface to form an array of contained resonant cavities therebetween. The ray of contained resonant cavities is readily employed in various applications including unique tunable optical filter rays, lens-less imaging systems, and multispectral imaging systems.

An illumination device includes: a light source that emits first light at a first wavelength; an integrator optical system that the first light enters; a wavelength conversion element that converts the first light transmitting through the integrator optical system into second light at a second wavelength different from the first wavelength; a wavelength separation element provided on an optical path of the first light between the integrator optical system and the wavelength conversion element; a pickup optical system that is provided between the wavelength conversion element and the wavelength separation element and receives the first light and the second light; and a chromatic aberration-correcting optical element provided at least one of between the integrator optical system and the wavelength separation element on the optical path of the first light and at downstream of the wavelength separation element on an optical path of the second light.

The invention discloses a parallel data processing method based on the hidden Dirichlet distribution model, which belongs to the data mining field. The method includes three solutions, including the multi-process parallel processing, the multi-thread parallel processing and the composite multi-process multi-thread processing; the data DM for being processed is divided into data segments in equal or unequal length in the three solutions; each data segment is provided with an index; each computer process / thread processes the corresponding data segment through applying the index, so as to obtainthe subject information of each data item and generate the local sufficient statistic; when the whole DM is processed, the global sufficient statistic is obtained through the merge of the local sufficient statistics so that the current Mi model is obtained through the estimation until the model becomes convergence. The parallel data processing method can utilize the multi-kernel parallel frame ofa single computer and the cluster large-scale parallel capability of multi-computer to realize the high-speed processing of the large-scale text sets and effectively reduce the memory usage during theparallel processing process.

The invention discloses a tube side type heat exchanger with a composite double-tube plate structure, which comprises a shell side barrel body (5), heat exchange tubes (4) and a heat exchange tube plate, the heat exchange tube plate is of an integrated structure comprising a base tube plate (2) and a covering tube plate (1), the circumference of which is sealed and the middle of which is provided with a cavity, and the cavity is a cavity which is sunken in the tubing area of the base tube plate (2) along the axial direction of the heat exchanger; the top of the base tube plate (2) is provided with an escape orifice (3) which is inserted into the base tube plate (2) along a direction perpendicular to the heat exchange tubes and communicates with the outside upwardly and the cavity internally; and the bottom of the base tube plate (2) is provided with an emptying orifice (6) which is inserted into the base tube plate (2) along a direction perpendicular to the heat exchange tubes and communicates with the outside downwardly and the cavity internally. The heat exchanger disclosed by the invention completely keeps the advantages of a double-tube plate heat exchanger, can effectively prevent the mixture of tube side medium and shell side medium, and also overcomes the defects of a lot of conventional double-tube plate structures, the machining difficulty of double-tube plate heat exchangers is effectively decreased, and the manufacturing cost of the double-tube plate heat exchangers is effectively reduced.

The invention relates to the technical field of network communication, and discloses a method for classifying and distributing messages on a mobile terminal, including step S1: sending the message received by the mobile terminal to a message channel; and step S2: judging whether the message in the message channel is a sensitive message , if it is a sensitive message, encrypt the message; step S3: according to the type of the message, send the message to the corresponding independent processing module for processing and then push it to the user. There are multiple independent processing modules, and each independent processing module Responsible for processing one type of message. The invention also discloses a system for classifying and distributing messages on the mobile terminal. The invention can quickly and efficiently classify, distribute and process the messages received by the mobile terminal.
