ESTIMATION OF LIQUID WEIGHT AND TYPE USING ROCKING MOTION : IMPROVING ESTIMATION ACCURACY USING BAYESIAN ESTIMATION
Get PDFHumans can estimate the approximate weight and type of an unknown liquid by shaking a container filled with the liquid. In this study, we focused on estimating the weight and type of an unknown liquid by shaking a container with a robot arm using Bayesian estimation. First, a robot arm was created and shook a container filled with various liquids in two different motions, providing prior information from a strain cage and a microphone. Next, the probability of estimating the contents of the containers was updated from the data obtained by shaking randomly selected containers to improve the accuracy. As a result, the weight and type of liquid were successfully identified
Random lasing from roughness structure on ZnO single crystal substrate
Get PDFRandom laser is a simple laser source consisting of a scatterer and an optical gain medium. Zinc oxide is a promising random laser material because it is inexpensive and high-quality crystals can be easily grown. In recent years, as a new random laser, a roughness structure formed on the surface of a gallium nitride single crystal substrate has been proposed. In this paper, we investigate laser oscillation features from the roughness structure on the zinc oxide single crystal substrate
Segmented Pulse Shaping Type Digital Direct Drive Speaker System for Switching Loss Reduction
Get PDFSegmented pulse-shaping digital direct-drive loudspeaker technology with FIR filters has been proposed by applying segmented pulse-shaping techniques in a digital direct-drive loudspeaker (DDDSP) with a system connected to an FIR filter． However, since the FIR filter outputs all the pulses (0011, 0101, 0110, 1001, 1010, 1100), it increases the switching losses of the loudspeaker．This paper proposes to reduce the switching loss of the loudspeaker by limiting and optimizing the type of output pulses of the FIR filter, and the simulation results are presented
DEGRATION OF MAGNETIC SHIELD MEASUREMENT ACCURACY CAUSED BY IMPERFECT TEST FIXTURE
Get PDFIn this study, we will explain the decrease in measurement accuracy due to the incompleteness of the evaluation jig used to measure the shield effect. The analysis is performed by using a pressure gauge sheet to reflect the actual contact conditions. It was confirmed that by changing the thickness, conduction area, physical property value, etc. of the contact part, the gap and conduction area due to poor contact between the shield material and the jig cause a decrease in measurement accuracy
RESEARCH ON MAGNETIC SHIELDING USING MAGNETIC POWDER
Get PDFCopper, conventionally used as a standard material for shielding materials, has been problematic because of its ineffectiveness against 100 kHz electromagnetic waves emitted by inverters inside electric vehicles. Therefore, we focused on magnetic materials with high specific permeability, and confirmed the shielding effect by conducting simulation analysis on shielding materials made of copper and magnetic materials
A NEURAL NETWORK MODEL THAT EXPLAINS THE OCCURRENCE AND DISAPPEARANCE OF OPTICAL ILLUSIONS IN LATTICE FIGURES
Get PDFThe principle of the Herman lattice illusion can explain this illusion phenomenon in the most powerful model at present. (It is a circular receptive field consisting of two regions, a concentric on-region, and an off-region.) However, although the most powerful visual model can explain the principle of the Herman lattice, it cannot explain the reason why the illusion disappears when the Herman lattice is distorted in a wave shape. And until now, the reason remains unexplained. In addition, the illusion of scintillating grid has not been elucidated, nor has the disappearance of the illusion of wavy figures of scintillating grids been clarified. Focusing on this, I decided to study. We will explain the occurrence and disappearance of optical illusions in these lattice figures, and also consider the neural network model
STRUCTURE ANALYSIS OF PATENT CLAIMS USING CLUE PHRASES AND ASSOCIATIVE PATEN RETRIEVAL BY DISTRIBUTED REPRESENTATION
Get PDFPatent information is a valuable source of information for research into existing research and understanding the latest research trends, and it is also necessary to conduct a thorough search to avoid infringing on the patent rights of other companies. However, since there are a huge number of patents and it is difficult for non-specialists to grasp the contents of patents due to their unique descriptions, natural language processing technology is expected to be utilized. In this study, as a support for patent searches, the structure of claims is analyzed based on clue clauses, and similarity judgments are made based on the distributed representation of BERT.As a result of the experiment, an accuracy of 0.406 was obtained for the similarity evaluation with patents in the reference literature.

DRIVE MECHANISM AND MOVEMENT CONTROL OF LIPOSOMES ENCAPSULATING GREEN ALGAE CHLAMYDOMONAS
Get PDFInteractions between biological membranes and substances that move spontaneously (active matter) are important in life phenomena. In particular, this interaction is deeply involved in cell movements such as amoeba movement and flagellar movement. In this study, to investigate the interaction between the biological membrane and active matter, Chlamydomonas were encapsulated in liposomes. And I attempted to analyze the deformation and movement of the liposome by Chlamydomonas, and to control movement. As a result, Chlamydomonas-encapsulated liposomes formed membrane protrusions, and these produced the driving force of moving. In addition, we were able to control migration by using osmotic pressure and phototaxis. These results could help develop research into moving synthetic cells and microrobots
INVESTIGATION OF THE LOCALIZATION OF PERILLA MOSAIC VIRUS IN Aculops thymi BY MICROSCOPY USING ULTRA-THIN SECTION AND IN SITU HYBRIDIZATION
Get PDFPerilla mosaic virus (PerMV), which infects perilla and causes mosaic symptoms, is transmitted by the rust mite Aculops thymi, a member of the Eriophyidae, and causes major problems in cultivation. Its structure in plant tissues is less clear. Similarly, its dynamics in the tissue cells of the mites have not been analyzed. In this study, I aimed to clarify the localization of the virus in the infected perilla leaves and mites by electron microscopy using ultra-thin section, and in situ hybridization with PerMV oligonucleotide probe. Electron microscopy revealed salivary glands in the mite but no virus particles in the cells, while in situ hybridization showed the localization of the virus in the phloem tissues of perilla and in the forward body of the mite
