Abstract:
The purpose of the present invention is to provide a novel method for producing cereulide and a derivative thereof; an intermediate for cereulide; and a novel cereulide derivative. A novel didepsipeptide, a novel tetradepsipeptide, a novel octadepsipeptide and a novel dodecadepsipeptide are prepared. A linear precursor of cereulide or a derivative thereof, which is composed of any one of the novel depsipeptides, is cyclized by forming an intramolecular amide bond.

An optical fiber (1) includes (i) an inner core (111) whose refractive index distribution has an α profile, (ii) an outer core (112) which surrounds the inner core (111), and (iii) a clad (12) which surrounds the outer core (112). In the optical fiber (1), Rd is set to not less than 0.15, where Rd is a ratio of a refractive index difference between the outer core (112) and the clad (12) to a refractive index difference between a center part of the inner core (111) and the clad (12).

Abstract:
A method for creating an image database comprising an extraction step of extracting reference feature vectors from a reference image which should be compared with a retrieval query image for object recognition, the reference feature vectors corresponding to local features at different positions of the reference image and representing the position and characteristics of each of the local features as a vector position, vector length, and a vector direction, a clustering step of creating a plurality of clusters consisting of different reference feature vectors in such a manner that each reference vector belongs to any of the plurality of clusters, a selection step of selecting the representative vector of the clusters from among the reference feature vectors of each of the clusters, and a step of associating the representative vector with the reference image and registering the representative vector associated therewith in the image database for the object recognition, wherein, in the clustering step, each of the clusters is created in such a manner that reference feature vectors at a near vector position belong to the same cluster, and in the selection step, reference feature vectors with long vector length are given priority to select the representative vector, and wherein the retrieval query image and the reference image are compared with each other by generating at least one query feature vector from the retrieval query image, and applying local search between the query feature vector and the representative vector, each of the steps being executed by computers.
Abstract:
Provided are a method of generating a low-capacity model capable of identifying an object with high accuracy, and creating an image database using the model, a processing program for executing the method, and a processing apparatus that executes the process. The method for compiling an image database that is used for a three-dimensional object recognition includes a steps of extracting vectors as local descriptors from a plurality of images each image showing a three-dimensional object as seen from different viewpoints, a model creating step of evaluating the degree of contribution of each local descriptor to identification of the three-dimensional object, and creating a three-dimensional object model systematized to ensure approximate nearest neighbor search using the individual vectors which satisfy criteria, and a registration step of adding an object identifier to the created object model and registering the object model into an image database. In the model creating step, the local descriptor to be used in the model is selected based on the contributions of the individual vectors which are evaluated in such a way that when a vector extracted from one image of one three-dimensional object is an approximate nearest neighbor to another vector relating to an image of the three-dimensional object seen from a different viewpoint, the vector has a positive contribution, whereas when the vector is an approximate nearest neighbor to another vector relating to a different three-dimensional object, the vector has a negative contribution. The processing program is designed to execute the method, and the processing apparatus executes the process.
Abstract:
An exhaust gas treating apparatus includes an adsorption tower (20) that has an adsorption layer filled with an adsorbent and a heat transfer path through which heat is transferred to the adsorption layer. The apparatus performs switching among the following processes: an adsorption process of introducing an exhaust gas from an engine (10) into the adsorption layer of the adsorption tower so that target components to be treated, including NO X , in the exhaust gas are adsorbed by the adsorbent; a desorption process of introducing the exhaust gas into the heat transfer path of the adsorption tower to heat the adsorption layer and introducing a desorption gas into the heated adsorption layer so that the target components are desorbed from the adsorbent, and a cooling process of introducing a cooling gas into the adsorption layer of the adsorption tower to cool the adsorption layer and introducing the cooling gas that has passed through the adsorption layer into an inlet of the engine. Thus, the apparatus can treat the exhaust gas with a small amount of energy consumption and without performing a wet treatment.

It is intended to provide a method of easily and economically producing starch which has an increased content of less digestible starch. The method of producing starch having a high content of less digestible starch is characterized by comprising contacting starch with hot water at a temperature of 160 to 260°C which has a pressure corresponding to the saturated vapor pressure at that temperature or more.
Abstract:
It is intended to provide to provide an apparatus for separating an adsorbate, that permits continuous separation of the adsorbate from a processing material containing solid particles, sticky substances and water-soluble proteins alone or in combination without pretreatment, and a method of continuously separating the adsorbate. In the present invention, the processing is carried out, while a loop adsorbent is circulated. Specifically, an adsorbate is adsorbed, not by supply of the processing solution through the adsorbent, but by contact thereof with the adsorbent. In addition, the adsorbent after desorption of the adsorbate is cleaned. As a result, provided are an apparatus for separating an adsorbate, that permits continuous processing and separation of the adsorbate even from a processing material containing solid particles, sticky substances and water-soluble proteins alone or in combination without pretreatment and a method of continuously separating the adsorbate.
