Geometrical Penrose Tilings are characterized by their 1-atlas
Rhombus Penrose tilings are tilings of the plane by two decorated rhombi such
that the decoration match at the junction between two tiles (like in a jigsaw
puzzle). In dynamical terms, they form a tiling space of finite type. If we
remove the decorations, we get, by definition, a sofic tiling space that we
here call geometrical Penrose tilings. Here, we show how to compute the
patterns of a given size which appear in these tilings by two different method:
one based on the substitutive structure of the Penrose tilings and the other on
their definition by the cut and projection method. We use this to prove that
the geometrical Penrose tilings are characterized by a small set of patterns
called vertex-atlas, i.e., they form a tiling space of finite type. Though
considered as folk, no complete proof of this result has been published, to our
knowledge
Maineen yhteys yrityksen taloudelliseen suoriutumiseen
Tiivistelmä. Maineen yhteydestä yritysten taloudelliseen suoriutumiseen on keskusteltu laajasti yhteiskunnassa viime vuosina. Erityisen paljon huomiota on saanut yrityksen vastuullisuus laaja-alaisesti, josta keskustellaan usein ympäristö- ja sosiaalivastuullisuuden ja hyvän hallinnon kautta eli ESG-termin alla. Yleisesti ottaen hyvämaineiset yritykset houkuttelevat ihmisiä hakemaan yritykseen töihin, ostamaan kyseisen yrityksen tuotteita ja investoimaan siihen. Maineen ajatellaan yleisesti olevan yrityksen tärkein aineeton pääoma.
Maineen ja taloudellisen suoriutumisen yhteyttä on tutkittu laajalti. Tämä tutkielma tarjoaa uutuusarvollisen näkökulman taloudellisen suoriutumisen yhteydestä Helsingin pörssin Large ja Mid cap yhtiöiden kokonais- ja ESG-maineeseen yksityissijoittajien kontekstissa. Tutkielma avaa myös teoreettista viitekehystä maineesta peliteoriassa, jotta ymmärrämme maineen yhteyttä yrityksen päätöksentekoon ja sitä kautta taloudelliseen suorituskykyyn. Tutkielman empiirisessä osuudessa vertaillaan miten eri taloudellisen suorituskyvyn mittarit korreloivat suhteessa maineeseen ja ESG:hen. Tämän lisäksi regressioanalyysin avulla etsitään maineen tai ESG:n selittäviä taloudellisia muuttujia.
Tutkielman tulokset osoittavat, että niin mainetta kuin ESG:tä voidaan selittää useilla taloudellista suorituskykyä mittaavilla muuttujilla regressioanalyysin avulla. Toisaalta vain osa aiemman tutkimuskirjallisuuden pohjalta valituista taloudellisista muuttujista korreloivat maineen tai ESG:n kanssa. Tämä on linjassa aiemman tutkimuskirjallisuuden kanssa, jota on tehty laajasti ympäri maailmaa viimeisten vuosikymmenten aikana.
Käytännön tasolla tutkielma tuottaa arvokasta tietoa erityisesti pörssiyhtiöiden johtajille maineen monimerkityksellisyydestä. Tutkielman tulokset korostavat laajan mainetyön merkitystä, joka linkittyy myös vastuullisuuteen. Kuitenkin taloudellisesta suorituskyvystä huolehtiminen on ensiarvoisen tärkeää, koska tutkielman perusteella se selittää yksityissijoittajien mainetta pörssiyhtiöistä

A Comparative Study of Vehicle Platoon with Limited Output Information in Directed Topologies
This paper aims to study and compare the effect of limited-output information in various directed topology to the performance of vehicle platoon. Two distributed controllers based on limited-output information will be compared to cooperative state variable feedback control which designed based on full-state information. The comparison will be conducted for four common directed topologies in the vehicle platoon application. Simulation analysis is performed in three scenarios, namely under normal operations, when the leader moves with constant acceleration and when the platoon is subjected to constant communication delay. Performances comparison will be observed from inter-vehicular distance response in each follower and the results will be displayed with respect to the follower vehicle index in the platoon configuration. Finally, the behavior of each control scheme in various topologies will be summarized

The History of Periodicals in Hungarian Secondary Mathematics Education Between 1867 and 1956
The purpose of this study was to determine how secondary mathematics education changes in Hungary between 1867 and 1956 were reflected in journal articles of that time. In an attempt to accomplish this purpose, the researcher sought to identify which major political and socioeconomic factors affected the role and content of periodicals, how the content and approach of the topics changed, and who were the most prominent and influential authors of the periodicals between 1867 and 1956. This research investigates Journal of the National Association of Secondary School Teachers, the first periodical devoted to Hungarian secondary education published between 1868 and 1944, and Teaching of Mathematics, the first Hungarian periodical dedicated to mathematic education published between 1953 and 1956. The researcher employed historical-research methodology to examine the articles of the periodicals and categorize them based on similar content such as curriculum, teaching methods, school mathematics, and book/textbook reviews. The study also provides brief summaries of several articles.
This research has shown that the history of Hungarian education in general was often influenced by foreign and domestic politics and ideologies. Studying journal articles provides a unique opportunity to observe real-time communication between educators and administrators and to analyze the effect of social and political changes which influenced mathematics education.
Between 1867 and 1956, Hungary underwent major political and social changes—a dual Monarchy with Austria, independence as a truncated state, and occupation by Germany and later the Soviet Union. These changes significantly altered Hungary as a country and impacted its education system. While every country has undergone political and ideological influences in its educational history, Hungary was particularly affected by neighboring countries such as Germany and later the Soviet Union.
Taking the broader perspective of the evolution of periodicals, this study demonstrated that the history of periodicals as a general form of scientific communication has passed through several stages. The journals, in some respects, are a bridge between educators and were affected by the political atmosphere of the country.
In general, this study has shown that Journal of the National Association of Secondary School Teachers and Teaching of Mathematics were heavily influenced by social and political changes in Hungary, as well as foreign influences from countries such as Germany and the Soviet Union. These factors collectively formed Hungarian mathematics education between 1867 and 1956
The Moderating Effect of Instant Runoff Voting
Instant runoff voting (IRV) has recently gained popularity as an alternative
to plurality voting for political elections, with advocates claiming a range of
advantages, including that it produces more moderate winners than plurality and
could thus help address polarization. However, there is little theoretical
backing for this claim, with existing evidence focused on case studies and
simulations. In this work, we prove that IRV has a moderating effect relative
to plurality voting in a precise sense, developed in a 1-dimensional Euclidean
model of voter preferences. Our results show that as long as voters are
symmetrically distributed and not too concentrated at the extremes, IRV cannot
elect an extreme candidate over a moderate. In contrast, we show plurality can.
Our methods develop new frameworks for the theoretical analysis of voting
systems, deriving exact winner distributions geometrically and establishing a
connection between plurality voting and stick-breaking processes.Comment: 42 pages; updated intro and title, added GitHub lin
