An Account of the Relation between Impersonal Subject Constructions and Evidentiality
Get PDFThis study explores the relationship between impersonal subject constructions and indirect evidentiality. The study demonstrates that evidentiality strategies based on verb complementation have become conventionalized in English, with impersonalization being widely used to indicate hearsay, quotative, and inferential evidence. Specifically, it argues that some impersonal subject constructions in English denoting hearsay information pertain to impersonalization, which contributes to the evidentiality strategy in terms of its (in)directness, generality, and reliability. The study also contends that the interpretation of the conceptualizer of copulative perception verb constructions and instances of co-occurring to-phrases develop a usage to confirm the perspectives of the speaker and hearer.departmental bulletin pape
中華人民共和國建國初期的留學生選拔—1954年至1956年上海市高中生、大學生的選拔
Get PDF本文以上海市留學生的選拔為主線，梳理了有關1954-1956 年選拔派往蘇聯的留學生的相關事實。通過對選拔實施過程的整理和分析，對決定和指導選拔的中央行政機構和具體實施選拔的地方機構進行了比較。
建國初期中華人民共和國剛剛成立，急需培養國家建設人才，因此開始了留學生的選派工作。但中國共產黨對社會地位低下者一視同仁的理念與走精英主義捷徑以增強國力的現實需要之間的矛盾，讓中央和地方的行政機構陷入了兩難的探索之中。本文釐清了兩者之間的差異。journal articl
Associative Decision Processes on Converging Branch System
Get PDFIn this paper, we consider finite-stage deterministic decision processes. The objective function is associative and the transition follows a converging branch system which is one of the nonserial systems. By using dynamic programming and invariant imbedding technique, the recursive equation is derived under the assumption that the order of decisions is predetermined.departmental bulletin pape
The Be+V-ing Construction (Progressive) and Personal Letters Written in the Late 18th Century
Get PDFThis paper discusses the semantic function of the progressive (called BV construction here), examining previous studies in historical, social, and cognitive linguistics, as well as pragmatics. Special attention is paid to two collections of letters written in the last decade of the 18th century. At the end of the century, grammatical prescriptions regarding the form were overturned in terms of its aspectual nature. Findings from the collections indicate that descriptions before the change seem to better illustrate the intrinsic function of the BV construction in Present-day English. That is to confine the speaker’s viewing frame through which she focuses on a phase in the course of the situation represented by the participialized verb. Identifying one basic core function of the progressive as such accounts for diverse facets of the construction which previous research has characterized the form by. For example, it explains why the construction is affinitive with conversational situations that Sairio (2018) brings to the fore. A quantitative survey on the construction in the collections being analyzed in context demonstrates how its social historical background has also influenced its actual use.departmental bulletin pape
Position control of a 3-link dual-arm underwater robot using model error compensator -Considering the difference in response speed between a vehicle and manipulators-
Get PDFResearch and development efforts are ongoing to control underwater robots equipped with manipulators (known as Underwater Vehicle-Manipulator Systems, or UVMS) that can perform underwater tasks in place of humans. We have also proposed a Resolved Acceleration Control (RAC) method, a position control approach for UVMS, and have validated its usefulness through experiments using a free-floating, 3-link dual-arm underwater robot. Now, the model of fluid forces used to control underwater robots has modeling errors. Furthermore, the response speed of the vehicle is much slower than that of the manipulator. To solve these problems, we propose a RAC method for UVMS with MEC, which takes into account the difference in response speed between the vehicle and manipulator, and demonstrate its effectiveness through experiments on the position control of a robot affected by periodic wave disturbances.conference pape
凸多面体の重なりを持つ／持たない展開図
Get PDF九州工業大学博士（情報工学）1 Introduction| 2 Preliminaries| 3 Overlapping unfolding for convex polyhedral| 4 The number of non-overlapping unfoldings in convex polyhedral| 5 ConclusionAn unfolding of a polyhedron is a flat polygon obtained by cutting along the polyhedron’s cutting lines and flattening its faces onto a plane. The origin of unfoldings can be traced back to Albrecht D¨urer’s work in 1525. Depending on the shape of the polyhedron and the method of unfolding, the resulting shape may overlap, where two distinct faces intersect on the plane, or their boundaries are in touch. When the cutting lines are restricted to the edges of the polyhedron, the unfolding is called an edge unfolding. Shephard proposed the conjecture that for any convex polyhedron, at least one non-overlapping edge unfolding exists; however, this conjecture remains
unsolved.
To solve this conjecture, some studies are ongoing. Horiyama et al. showed that the edge unfoldings of Platonic solids and five types of Archimedean solids do not have overlaps. On the other hand, overlapping edge unfoldings have been found for five other types of Archimedean solids. There remains the problem of whether overlapping edge unfoldings exist for other convex regular-faced polyhedra, such as the snub cube, icosidodecahedron, rhombitruncated cuboctahedron, Archimedean prisms, Archimedean antiprisms, and Johnson solids.
For cuboids, when the cutting lines are aligned with the unit squares on the faces, the unfolding is called a lattice unfolding. Uno showed that the lattice unfolding of a 1×1×z cuboid, where z ≥ 3, has overlapping lattice unfoldings, and Mitani et al. showed an overlapping lattice unfolding for an x × y × z cuboid with x ≥ 1, y ≥ 2, and z ≥ 3. Conversely, Hearn showed that the lattice unfolding of a 1×1×2 cuboid does not overlap, and Sugihara demonstrated the same for a 2 × 2 × 2 cuboid. However, determining the conditions under which overlapping lattice unfoldings exist for cuboids with diagonal lattice cutting lines remains an open problem.
In this study, we address two main problems. The first problem is determining whether a given polyhedron has overlapping unfoldings. The second problem is counting the number of overlapping and non-overlapping unfoldings when a given polyhedron has overlapping unfoldings.
For the first problem, we introduce an algorithm called rotational unfolding, which efficiently determines whether overlapping unfoldings exist for a given polyhedron. The basic principle of our method is similar to the rolling and unfolding method proposed by DeSplinter et al., but it is extended to n-gons by proposing pruning techniques that use a polyhedron’s distance properties and symmetry. Using this algorithm, we show the existence of overlapping unfoldings for both edge unfoldings of convex regular-faced polyhedra and lattice unfoldings of cuboids. As a result, we solve the problem of whether overlapping edge unfoldings exist for convex regular-faced polyhedra and present the conditions for overlapping lattice unfoldings in cuboids with diagonal lattice cutting lines.
For the second problem, we propose an algorithm to count non-overlapping unfoldings in polyhedra that have overlapping unfoldings. The algorithm first enumerates the minimal overlapping partial unfoldings (MOPUs), which are the minimal units of edge unfoldings with overlaps. Then, we construct a zero-suppressed binary decision diagram (ZDD) representing non-overlapping unfoldings by subtracting the ZDDs of overlapping edge unfoldings containing the MOPUs from the ZDD representing all edge unfoldings. By applying this algorithm, we calculate the number of non-overlapping edge unfoldings for several convex regular-faced polyhedra and lattice unfoldings of cuboids. These results provide partial answers to the problems of counting overlapping and non-overlapping unfoldings for given polyhedra.九州工業大学博士学位論文 学位記番号:情工博甲第408号 学位授与年月日:令和7年3月25日令和6年度doctoral thesi
Fundamental Investigation on Contactless and Continuous Blood Pressure Measurement by Impinging Jet Flow and Imaging Photoplethysmography
Get PDFDue to the recent COVID-19 infection spreading, contactless measurement of vital information has been required at hospitals. On the other hand, as for measurement of continuous blood pressure (BP) and its fluctuations, it has been more important to find a high risk of diseases earlier. Although most of them are obtained by a mechanical contact sensor based on principle of tonometry, we have proposed a novel method by ejecting jet flow and a camera for measuring BP without contact, which can detect continuous BP and its fluctuations. However, it has not been confirmed yet whether the continuous measurement of blood pressure is possible or not in our previous investigations. In this study, to develop this contactless and continuous BP measurement system that uses the deformation of blood vessels, effects of the jet timing and pulse duration on the behaviour of the pulsating elastic tube are investigated. In the experiments, a silicon tube is used to simulate a blood vessel, and the fluid is circulated as a pulsatile flow. The jet flow is ejected from a nozzle to the tube surface, and internal pressure is measured by a pressure sensor. From comparing the internal pressure with displacement of elastic tube surface, it was concluded that 1) it is possible to control jet pressure that does not affect the internal pressure in the tube, 2) it was suggested that the averaged displacement by impinging jet flow follows the averaged internal pressure in the tube at the same time, and 3) internal pressure measurement by short duration time of jet pulses can be applied to continuous BP measurement.journal articl
Domain Knowledge Integration with Chain of Thought and Knowledge Prompting in Text to Motion Generation
Get PDFIn this paper, we propose a Zero-shot Chain-of-Thought Knowledge Prompting (ZCKP) technique to diversify text-to-motion generation by infusing domain expertise into pretrained models without requiring retraining. Current text-to-motion generation models rely heavily on limited datasets, which lack diversity. Generating specialized motions, such as those influenced by age, gender, or physical disabilities, typically requires retraining on custom datasets, an approach that is both computationally expensive and resource-intensive. ZCKP addresses this limitation by integrating instruction-driven CoT prompting into text-to-motion models. This method dynamically incorporates domain-specific knowledge, such as inverse kinematics and physical laws, enabling the generation of specialized, realistic, and physically plausible motion sequences in a zero-shot setting. To evaluate its effectiveness, the model was tested in age-based motion generation for toddlers and elderly individuals (healthy and disabled). Inter-class diversity scores demonstrate the model’s ability to produce varied motions, with Euclidean distances ranging from 56.23 to 78.15 and cosine value from 0.53 to 0.81. These scores indicate that motions across different age groups are distinct and diverse. Meanwhile, intra-class homogeneity scores confirm the generation of realistic and consistent motions within each group, with Euclidean distances ranging from 12.36 to 36.97 and cosine value from 0.12 to 0.32. These results highlight the model’s capacity to maintain coherence and naturalness while introducing diversity. By reducing the dependency on retraining and computational overhead, ZCKP offers a scalable and flexible solution for domain-specific text-driven motion generation.journal articl
