<p>Clustering is the task of dividing an input dataset into groups of objects based on their similarity. This process is frequently required in many applications. However, it is computationally expensive when running on traditional CPUs due to the large number of connections and objects the system needs to inspect. In this paper, we investigate the use of NVIDIA graphics processing units and their programming platform CUDA in the acceleration of the Euclidean clustering (EC) process in autonomous driving systems. We propose GPU-accelerated algorithms for the EC problem on point cloud datasets, optimization strategies, and discuss implementation issues of each method. Our experiments show that our solution outperforms the CPU algorithm with speedup rates up to 87X on real-world datasets.</p>

人工軽量骨材は市場に出てすでに8カ年を経過し,最近2~3年間の生産量は急上昇である。昭和45年度はメーカ7社の合計で生産量は約120万m<SUP>3</SUP>に及んでいる。したがって,数年前までは新材料,新工法のテーマの-つとして取り上げられ,調査,研究やシンポジウム,講習会の格好の対象となっていたが,そろそろ建設界一般に浸透してきた状態になったので,ここらで問題点を整理してみることも意義があることと思われる。日本建築学会関東支部主催「人工軽量骨材に望むもの」シンポジウム(昭46.1.21)の声も参考しながら筆者の気の付いた問題点について若干触れることにする。独りよがりの空論もあるかも知れないがお許しいただきたい。

子ども達の取り巻く環境が急速に変容しつつある現在の情報社会では、意識してもしなくともヒトはその影響を強く受ける。さらに、文明は次の世代をひ弱にすると言うが、その兆しが現れている。ところでヒトは目に見える地球上の環境問題等には目を向けるがヒト自体の内面的な面にはあまり注意を向けないようである。このような観点から独断と偏見を顧みず、教育の試論を述べる。

少子化対策には「人口政策」と「ウェルビーイング(健康で幸せな暮らしの実現)」の2つの面がある。この2つの面を整理し,国・基礎自治体・企業や社会・個人がそれぞれどのようなスタンスで少子化対策に臨むべきかの議論が必要である。1990年の1.57ショックに始まった日本の少子化対策を見ると,ややもすると「人口政策」と「ウェルビーイング」の議論が混同してきた面も否めない。しかしながら,さまざまな試行錯誤を経て2015年4月に,今後の日本社会の少子化対策のあるべき姿を定めたものと言える「子ども・子育て支援新制度」がスタートした意義は大きい。本稿では1990年から今日までの四半世紀に及ぶ少子化問題とその対策においてなされてきたことを振り返りつつ,今後の少子化対策としての子育て支援について考える。

Thomas Hobbes employs the counsel/command theory to argue that clergies are to be subordinate to the sovereign. He shows that bishops are counsellors and the word of the Bible is counsel. The theory of counsel functions as the denial of bishops' right to interpret the Bible and their power of excommunication. While Hobbes in De Cive admits some room for ordained bishops to influence the church governance, he in Leviathan totally denies their iure divino authority. He uses this reasoning to criticise not only Catholicism but also Anglican Episcopacy and Presbyterianism, which shows that he is free from any existing sects.

Hearn (1970) notes that what Hume calls ‘general rules’ should be distinguished into two types. The first one are the eight rules Hume mentions in Treatise 1.3.15 as normative; the second one are the mere natural inclinations of our imagination. Following Hearn, many scholars try to extract from the writings the distinguishable criterion of ‘good’ rules. On the contrary, I try to understand the common feature, or the origin, of apparently different types of general rules. My interpretation will offer a naturalistic explanation of epistemic normativity of Hume's general rules.

Burke's “A Philosophical Enquiry into the Origin of our Ideas of the Sublime and Beautiful” should be read as the expression of his religion as has been asserted by F. P. Lock, Ian Harris and others. We can see his religion in “A Note-Book of Edmund Burke”, in which he says “Hence Moral Duties are included in Religion, and enforced by it”. Religion enforces men to perform their moral duties. The sublime is almost equivalent to the feeling of divine or delightful horror to the power of God. Burke tried to remind us of the fear to God through his discourse on the sublime. In this point, we can say that Burke revolted against the 18th century when the God of Justice was stepping back to the scenery of this world.

A pamphlet titled The Discoverie of a Gaping Gulf, in which John Stubbs made the comprehensive argument over Elizabeth Iʼs marriage, was published in August 1579. In Gaping Gulf, showing a strong aversion to France, Stubbs insisted that (in terms of religion, history, international war and politico-legal custom) it is impossible for England to tie the knot with France and called for solidarity among Englishmen. In addition, he demanded ʻtrue Englishmanʼ should provide ʻfaythfull counsaileʼ about this issue. According to Stubbs, ʻcounselorsʼ must be ʻChristian commonwealthmenʼ, who dedicate themselves to church and ʻcommonwealthʼ (a community aimed at the common good). If we exploit A.D. Smithʼs argument here, Stubbsʼ ʻcountry loueʼ shows the ideological transition from ʻethnicityʼ to ʻcitizenshipʼ in Tudor England.

Hume establishes the first principle in his study of human nature: ʻall our simple ideas proceed ... from their correspondent impressionsʼ(T 1.1.1.11). It is so primary for his empiricism that based on it, he argues about space and time, a necessary connection between cause and effect, and even vice and virtue. But then why does he present the missing shade of blue as a contradictory example to it? In this paper, I will start by describing the resemblance thesis and the causal thesis involved in his first principle. I will then explain why the missing shade of blue is not a counterexample to the former thesis, but to the latter. Finally, I will argue why he does present the missing shade of blue though it does not affect his first principle.

Hume sometimes refers to an idea of a relation, and according to Humeʼs Copy Principle, this means that there must be a correspondent impression of the relation. However, such an impression, if any, would also raise certain interpretative problems with regard to the consistency of Humeʼs philosophy. In this paper, I try, first, to suppose and characterize the impression of a relation and to complement Humeʼs theory of relation with reference to “intuition,” “necessary connection,” and “calm passion.” Then I attempt to appraise the consistency between Humeʼs theory of relation and his Copy Principle, from the viewpoint of his philosophical purpose.
