Elastic Wave Property of Concrete Decomposed by Steam Pressure Cracking Agent
A steam pressure cracking (SPC) agent is a method that can dismantle concrete safely and quickly. In previous studies, the authors showed that the direction of the crack could be controlled by the tensile stress at the induction holes and not by the compressive stress at the SPC hole. We demonstrate that the compression elastic wave changes to a tensile wave when the wave is reflected at the free surface of the induction hole. We also examined the properties of the concrete by developing an elastic wave measuring system that is difficult to break down even in high-temperature, wet, and radiation environment. The elastic wave velocity change in the four concrete types was less than 4%. It was found that the standard deviation value, σ, changed four times. Therefore, it is possible to determine the deterioration of the internal structure of concrete using the standard deviation value σ, which indicates the dispersion of the elastic wave velocity

MD 木を用いた移動オブジェクト管理<論文>
The progress in wireless technologies and the advancement of GPS accuracy makes us to get the positions of moving objects easily. Mobile instrument spreads across our social life quickly, so it is important to manage the moving objects data for emerging applications with those technologies. In this paper, we describe an efficient index structure MD-MOtree, which is based on MD-tree, to deal with moving objects data that has frequent insertion and deletion. There are no overlaps and no needs to periodical restructuring of the tree structure by not integrating internal nodes on its delete process. And its combined delete-insert algorithm in each object cut down the processing time. The good performance of MD-MOtree for managing the moving point objects is shown by simulation experiments.textapplication/pdfdepartmental bulletin pape
チョッパとインバータを用いた電気二重層コンデンサの電圧バランス回路<論文>
Electric double layer capacitors(EDLCs) are used in series connection and the voltage balance among EDLCs is important. The voltage balance circuit with inverter has the merits of simple and low cost. However the voltage drop at diodes and transistors impedes the voltage balance operation. We have developed a new voltage balance circuit using chopper and inverter. The chopper steps up the input voltage of inverter to compensate the voltage drop. This paper describes the new voltage balance circuit and the experimental results in detail.textapplication/pdfdepartmental bulletin pape
Is Adjuvant Chemotherapy Necessary in Patients with Early Endometrial Cancer?
Background: We investigated whether there was a difference in prognosis between patients with stage IA endometrial cancer with and without lymphovascular space invasion. Methods: We enrolled patients with stage IA (pT1aN0M0) endometrial cancer admitted to our hospital from 2009 to 2018. All patients underwent hysterectomy, bilateral salpingo-oophorectomy, and systematic pelvic lymphadenectomy. We immunopathologically evaluated the presence or absence of lymphovascular space invasion in the tumor tissue using hematoxylin and eosin, Elastica-van Gieson, and podoplanin staining. We analyzed disease-free and overall survival and calculated patients’ survival distribution using the Kaplan–Meier method and log-rank test. The multivariate analysis was performed to determine the prognostic factors. Results: A total of 116 patients were included. The median age of the patients was 57 (range, 30–78) years, and the histological subtype revealed 98 and 18 cases of types 1 and 2, respectively. The median follow-up period was 71.9 (range, 10.8–149) months, and the 3-year disease-free and 3-year overall survival rates were 94% and 99%, respectively. The disease-free and overall survival rates were significantly shorter in type 2 patients than in type 1 patients (type 2 vs. type 1; 77% vs. 97%, P < 0.01, 94% vs. 100%, P = 0.014, respectively). The univariate and multivariate analyses showed that there were no significant differences in disease-free survival between the lymphovascular space invasion-positive and -negative groups among type 1 cases. Conclusion: There was no difference in prognosis between patients with stage IA and type 1 endometrial cancer with and without lymphovascular space invasion.journal articl
