Tematy:: rozumienie
dystans czasowy
understanding
time distance
Opis:: W artykule podejmowane jest zagadnienie dziejowo określonego rozumienia. W przyjętej tu perspektywie hermeneutycznej podmiot rozumiejący musi uświadomić sobie własną dziejowość i dziejowość swojego sposobu rozumienia, by odkryć prawdę o przedmiocie poznawanym. Co więcej, to właśnie zakorzenienie w dziejowej tradycji usprawnia nas do rozumienia w ogóle.
The hermeneutical approach raises the relevance of concioussness of twofold relationship between understanding and historical tradition. Hermeneutic reflection involves the correction of self-understanding and emphasizes that the possibility of reaching understanding is available to us only by our belonging to a historical community.

Opis:: Z geometrycznego punktu widzenia obszarami optymalnego zasięgu obiektów oddziałujących na otoczenie w różny sposób (jednostki świadczące usługi produkcyjne, handlowe, socjalne, kulturalne, pedagogiczne, ratunkowe, bezpieczeństwa) są obszary określone według diagramów Voronoja, w określonej metryce przestrzeni (w praktyce najczęściej miejskiej indukowanej przez sieć dróg). W odniesieniu do jednostek takich jak pogotowie ratunkowe, pogotowia awaryjne (różnego rodzaju), straż pożarna, policja i, interesująca nas szczególnie tym artykule, dostawa betonu towarowego, ważną sprawą jest nie tyle odległość, co czas (a dokładniej odległość czasowa). Przy tworzeniu diagramów Voronoja należałoby posługiwać się właśnie odległością czasową, czyli korzystać z odległości z wagami. W artykule zaproponowano sposób wyznaczania odległości czasowych (w efekcie obszarów zasięgu betonowni) z wykorzystaniem sformułowanego (w tej pracy) współczynnika czasu przejazdu pojazdu w danej porze dnia. By dokonać optymalizacji lokalizacji betonowni wprowadzono wskaźniki transportochłonności czasowej.
From a geometrical point of view, areas of optimum range of objects that affect the environment in different ways (providers of production, commercial, social, cultural, educational, rescue, security services) are defined by the Voronoi diagrams in a given metric space (in practice, it is mostly urban space induced by the network of roads). With regard to entities such as ambulance, emergency services (all types), fire brigade, police, and the supply of ready-mixed concrete were discussed in the article, not so much the distance as time is the most essential (and more specifically the time gap). During creating the Voronoi diagrams weighted distance should be used. This paper proposes a method of determining the distance of time (and as a result coverage areas of a concrete plant time range), formulated using the vehicle travel time index in the given time of day. In order to optimize the location of concrete plant special indicators, that measure the time needed to cover the distance time transport intensity, were introduced.

Opis:: We investigate clustering of 2D contours which represent cross-sections of rotationally symmetric objects. We propose modiﬁcations of the existing representations of digitized 2D contours and similarity measures. In particular, we represent each of the investigated objects as a single number and two functions and we use the DTW distance to measure their similarity. We apply our method to clustering of pottery fragments.

Opis:: Time is a key variable in the field of economics and finance. However, most of the classic approaches to economic problems are static. In this paper, we first review the existing literature on the use of multiobjective techniques to control dynamic systems within the area of economics and finance. We also tackle the question of which measure should we use to evaluate alternative solutions. To this end, we elaborate on the meaning added by the selection of a parameter in a family of distance functions used to evaluate alternative solutions.

Tytuł:: Comparing changes over time for two phenomena
Autorzy:: Miłek, Michał
Powiązania:: https://bibliotekanauki.pl/articles/584959.pdf
Data publikacji:: 2015
Wydawca:: Wydawnictwo Uniwersytetu Ekonomicznego we Wrocławiu
Tematy:: time series comparing
permutation test
distance measure
Opis:: Statistical analyses in economics are often based on explaining the phenomena by comparing time series. The purpose of such types of analyses is to find out the similarity and schematic behavior of phenomena which appear in the data. Usual time series are compared with the use of a different similarity measure which, in accordance with the literature, could be divided into four categories. In this article, I propose a method that allows to indicate whether two time series are generated by the same stochastic processes. For this purpose, I analyze a method based on a permutation test. The idea of this test is much simpler than the tests based on theoretical distributions. I also conducted a simulation analysis based on the data generated according to different scenarios, subsequently comparing the results of that analysis.

Tematy:: vocational education

distance learning
Opis:: The outbreak of the COVID-19 pandemic forced the closure of schools in Poland. It was a challenge, especially for vocational education. Distance learning reduced the time devoted by some students to learning, and thus probably also the amount of their knowledge and skills. The authors indicate the key factors of how the transition to distance learning influenced the time devoted by students to education. This paper investigates to what extent the education system managed to adapt to the pandemic conditions and which actions are of special importance for the future. The analysis is based on the results of a survey of vocational school students in Poland who studied in the last grades during the pandemic.

Tytuł:: Близина/далечина при средбата од „онаа страна”
Proximity/distance at the meeting on “the other side”

Data publikacji:: 2012
Wydawca:: Uniwersytet im. Adama Mickiewicza w Poznaniu
Tematy:: proximity/distance
folk healers
charms and incantations
space
time
Opis:: Folk healers and their ability to heal can be connected with death or the being owned by death. This deeply archaic structure is evident in how knowledge is acquired, namely that it is passed on from mother to daughter or granddaughter/grandson in a place that suggests a connection to the other world (water, bridge). It is also evident in the fact that the women performing charms must be postmenopausal. Also important is the fact that when knowledge is acquired through dreams and visions, the soul of the initiate or the initiate him- or herself must be in touch with the other world and then return to life by passing over a thin line: a bridge as wide as a hair or a straw. This is a condition akin to death followed by eventual recuperation. Another important point is the difference in physical appearance to those treated, for example, old, white, a pale face, piercing eyes, small, slouching, etc. All these incorporate the idea that the communication with the “other world”, “the other side”, is always given to those people that somehow were in touch with the other world, which from that perspective are far from us, but originating from our environment and transferring the message that they are also close to us. The connection with the other side, with the other, distanced world was also seen in the time-space structure on the charms.

Tematy:: dynamic temperature
temperature time series
similarity measure
distance measurement
Opis:: Different temperature sensors show different measurement values when excited by the same dynamic temperature source. Therefore, a method is needed to determine the difference between dynamic temperature measurements. This paper proposes a novelty approach to treating dynamic temperature measurements over a period of time as a temperature time series, and derives the formula for the distance between the measurement values using uniform sampling within the time series analysis. The similarity is defined in terms of distance to measure the difference. The distance measures were studied on the analog measurement datasets. The results show that the discrete Fréchet distance has stronger robustness and higher sensitivity. The two methods have also been applied to an experimental dataset. The experimental results also confirm that the discrete Fréchet distance performs better.

Opis:: The J-PET detector being developed at the Jagiellonian University is a positron emission tomograph composed of the long strips of polymer scintillators. At the same time, it is a detector system that will be used for studies of the decays of positronium atoms. The shape of photomultiplier signals depends on the hit time and hit position of the gamma quantum. In order to take advantage of this fact, a dedicated sampling front-end electronics that enables to sample signals in voltage domain with the time precision of about 20 ps and novel reconstruction method based on the comparison of examined signal with the model signals stored in the library has been developed. As a measure of the similarity, we use the Mahalanobis distance. The achievable position and time resolution depend on the number and values of the threshold levels at which the signal is sampled. A reconstruction method as well as preliminary results are presented and discussed.

Tematy:: alcohol consumption
driver´s reaction time
stopping distance
driver´s attention
Opis:: Each driver should drive according to the actual road traffic rules of the country in which he is currently located. The law systems of various states of Europe allow an increased maximal blood alcohol level of driver. As the fact that no small number of road accidents is caused because of the influence of alcohol on the driver, it is necessary to focus the attention of the society on this issue. The paper deals with the influence of alcohol on the reaction time of the driver. The effect of alcohol on driver behaviour has been studied. The reaction time of several drivers from a selected group of people was measured. At first (before alcohol drinking) the physical and mental condition of the drivers was assessed, using a series of question. Subsequently, the measurements were carried out with a sober driver. After this initial measurement the driver began to drink alcohol and after 20 minutes the level of alcohol in driver´s breath was determined by certificated equipment. It followed by starting the vehicle at a speed of approximately 50 km/h and stopping the vehicle in front of the simulated barrier. During the tests of the stopping distance, the mean fully developed deceleration was explored as the supporting variables. As the most important variable was the driver´s reaction time. It was researched by using of the video-analysing from two synchronized cameras. One camera was placed on the windscreen to monitor the situation in front of the vehicle, the other one monitored the movement of the driver´s feet. The aim of this paper is to focus on the fact that there is a dependence between the amount of consumed alcohol and the driver´s reaction time, which significantly affects the road safety. The reaction time of the driver directly influences to the stopping distance thus it is resolute for stopping the vehicle before a barrier.
