An application of the finite element method to curve fitting

An application of the Finite Element Method (FEM) to the solution of a geometric problem is shown. The problem is related to curve fitting i.e. pass a curve trough a set of given points even if they are irregularly spaced. Situations where cur ves with cusps can be encountered in the practice and therefore smooth interpolatting curves may be unsuitable. In this paper the possibilities of the FEM to deal with this type of problems are shown. A particular example of application to road planning is discussed. In this case the funcional to be minimized should express the unpleasent effects of the road traveller. Some comparative numerical examples are also given.

Od demokracji "wirtualnej" ku europejskiej: Geneze i konsekwencje przelomu politycznego w Moldawii. Prace OSW 32/2009. = From "virtual" to European democracy - the origins and consequences of the political breakthrough in Moldova. OSW Study 32/2009

2009 may become a turning point in the history of post-Soviet Moldova. The country’s political class and society are faced with a fundamental choice. On the one hand, if the Party of Communists of the Republic of Moldova, which has governed the country since 2001, remains in power, this would mean a consolidation of the authoritarian rule of the party leader Vladimir Voronin, perpetuation of the superficial nature of democratic institutions and a continuation of the manoeuvring between the European Union and Russia (with the increasing risk of falling into the latter’s exclusive zone of influence). On the other hand, the take over of political power by the opposition parties creates an opportunity for Moldova to resume building a democratic, pluralistic political system based on the rule of law and to develop closer links with the European Union within the framework of the European Neighbourhood Policy, including the Eastern Partnership.

Discussing Citizenship in Egypt: A comparative study of the post-2011 political debate. EUSpring Working Paper No. 3 [also Arab Citizenship Review No. 8], 20 July 2015

From the Introduction. Having simultaneously evolved theoretically and in political practice over centuries, the concept of citizenship is one of the most complex in political and social sciences. It correlates and intersects with another set of concepts and values, especially the rule of the law and democracy. Its historical evolution, thanks to individuals and citizens’ movements’ struggle to gain equal rights in their political communities, needs to be captured by theory.

Size exclusion chromatogram of the Tannermoor 2009 sample after saltout experiments

Samples from a pristine raised peat bog runoff in Austria, the Tannermoor creek, were analysed for their iron linked to natural organic matter (NOM) content. Dissolved organic carbon < 0.45 µm (DOC) was 41 to 64 mg/L, iron 4.4 to 5.5 mg/L. Samples were analysed applying asymmetric field flow fractionation (AsFlFFF) coupled to UV-Vis absorption, fluorescence and inductively coupled plasma mass spectrometry (ICP-MS). The samples showed an iron peak associated with the NOM peak, one sample exhibiting a second peak of iron independent from the NOM peak. As highland peat bogs with similar climatic conditions and vegetation to the Tanner Moor are found throughout the world, including areas adjacent to the sea, we examined the behaviour of NOM and iron in samples brought to euhaline (35 per mil) conditions with artificial sea salt. The enhanced ionic strength reduced NOM by 53% and iron by 82%. Size exclusion chromatography (SEC) of the samples at sea-like salinity revealed two major fractions of NOM associated with different iron concentrations. The larger one, eluting sharply after the upper exclusion limits of 4000-5000 g/mol, seems to be most important for iron chelating. The results outline the global importance of sub-mountainous and mountainous raised peat bogs as a source of iron chelators to the marine environment at sites where such peat bogs release their run-offs into the sea.

Cs-137 and Co-60 isotopes and sedimentation rates in Late Holcene sediments from the Northwestern Black Sea

Results of measurements of Cs-137 and Co-60 concentrations in bottom sediments of the Northwestern Black Sea indicate inhomogenity of their distribution both over the studied area and along sediment cores. Intermittency of sediment layers with different concentration of radionuclides in the cores reflects active horizontal movements and redistribution of sediments on the shelf and continental slope. As a result sediment layers dated by the Chernobyl mark as seven years old were found in the 5-7 cm depth layer. Maximum Cs-137 concentration in the surface sedimentary layer on the shelf was 42 mBq/g. Maximum Co-60 concentration of 1320 mBq/g was measured due to a hot particle. No correlation was found between Cs-137 and the Co-60 contents.

A comparison between static and kinetic visual attention as a means of detecting age-related deterioration of the visual system and driving performance

A critical review of previous research revealed that visual attention tests, such as the Useful Field of View (UFOV) test, provided the best means of detecting age-related changes to the visual system that could potentially increase crash risk. However, the question was raised as to whether the UFOV, which was regarded as a static visual attention test, could be improved by inclusion of kinetic targets that more closely represent the driving task. A computer program was written to provide more information about the derivation of UFOV test scores. Although this investigation succeeded in providing new information, some of the commercially protected UFOV test procedures still remain unknown. Two kinetic visual attention tests (DRTS1 and 2), developed at Aston University to investigate inclusion of kinetic targets in visual attention tests, were introduced. The UFOV was found to be more repeatable than either of the kinetic visual attention tests and learning effects or age did not influence these findings. Determinants of static and kinetic visual attention were explored. Increasing target eccentricity led to reduced performance on the UFOV and DRTS1 tests. The DRTS2 was not affected by eccentricity but this may have been due to the style of presentation of its targets. This might also have explained why only the DRTS2 showed laterality effects (i.e. better performance to targets presented on the left hand side of the road). Radial location, explored using the UFOV test, showed that subjects responded best to targets positioned to the horizontal meridian. Distraction had opposite effects on static and kinetic visual attention. While UFOV test performance declined with distraction, DRTS1 performance increased. Previous research had shown that this striking difference was to be expected. Whereas the detection of static targets is attenuated in the presence of distracting stimuli, distracting stimuli that move in a structured flow field enhances the detection of moving targets. Subjects reacted more slowly to kinetic compared to static targets, longitudinal motion compared to angular motion and to increased self-motion. However, the effects of longitudinal motion, angular motion, self-motion and even target eccentricity were caused by target edge speed variations arising because of optic flow field effects. The UFOV test was more able to detect age-related changes to the visual system than were either of the kinetic visual attention tests. The driving samples investigated were too limited to draw firm conclusions. Nevertheless, the results presented showed that neither the DRTS2 nor the UFOV tests were powerful tools for the identification of drivers prone to crashes or poor driving performance.

Organisational learning, climate change and the tragedy of the commons in China

This paper ends with a brief discussion of climate change and suggests that a practical solution would be to transfer much of the current air, sea and long-haul trucking of intercontinental freight between China and Europe (and the USA) to maglev systems. First we review the potential of Asian knowledge management and organisational learning and contrast this against Western precepts finding that there seems to be little incentive to 'look after one's fellows' in China (and perhaps across Asia) outside of tight personal guanxi networks. This is likely to be the case in the intense production regions of China where little time is allowed for 'organisational learning' by the staff and there is little incentive to initiate 'knowledge management' by senior managers. Thus the 'tragedy of the commons' will be enacted by individuals, township, and provincial leaders upwards to top ministers - no one will care for the climate or pollution, only for their own group and their wealth creation prospects.

A kínai reformfolyamat politikai gazdaságtani logikája (The politico-economic logic of the Chinese reform process)

Kína az elmúlt több mint három évtizedben szegény, elmaradott országból a világgazdaság egyik legfontosabb szereplője lett. Szocialista rendszerét egy sajátos kapitalista rendszer váltotta fel, miközben politikai struktúrája lényegében változatlan maradt. A folyamatok során a vezetés mindvégig ügyelt arra, hogy a kommunista párt egyeduralmát semmi se veszélyeztethesse, ugyanakkor megfelelő források álljanak rendelkezésre hatalma megtartásához. A tanulmány a kínai reformfolyamatot politikai gazdaságtani szempontból vizsgálja, különös figyelmet szentelve az intézményi változásoknak. Bemutatja, milyen okok és tényezők álltak a reformok elindításának hátterében, milyen változások következtek be a szereplők érdekviszonyaiban a reformok előrehaladtával, és mire lehet számítani a reformok jövőjét illetően. Úgy tűnik, hogy a jelenlegi rendszer érdekviszonyai a reformok folytatása ellen hatnak, ellehetetlenítve a piacgazdaság intézményrendszerének további kiépítését. A járadékok és privilégiumok az elitet abban sem teszik érdekeltté, hogy komolyabb politikai reformokat hajtson végre, így a kialakuló csapdahelyzet megakadályozza az átmenet kiteljesedését. ____ In the last three decades China has risen from being a poor and underdeveloped country to being one of the most important players in the world economy. Its planned economy has been replaced by a capitalist system, but its political structure has remained essentially unchanged. The leaders during the reform process have sought constantly to avert dangers to the rule of the Communist Party and gain access to valuable resources that allow power to be retained. The study approaches the Chinese reform process from a politico-economic point of view, focusing primarily on institutional changes. It reveals the main factors behind the various phases of reform, the constantly changing interests of the players, and the possible future of the process. It seems that under the current authoritarian regime, there are vested interests working against a continuation of the reforms and precluding full establishment of the institutional framework of a market economy. The elite is also deterred from implementing serious political reforms by the current rents and privileges. This leads to a trap that prevents completion of the transition process.

Database of the GLAMAP project

A uniform chronology for foraminifera-based sea surface temperature records has been established in more than 120 sediment cores obtained from the equatorial and eastern Atlantic up to the Arctic Ocean. The chronostratigraphy of the last 30,000 years is mainly based on published d18O records and 14C ages from accelerator mass spectrometry, converted into calendar-year ages. The high-precision age control provides the database necessary for the uniform reconstruction of the climate interval of the Last Glacial Maximum within the GLAMAP-2000 project.

Coccolithophore abundance and biometry in the South China Sea, 2014

Coccolithophore contributions to the global marine carbon cycle are regulated by the calcite content of their scales (coccoliths), and the relative cellular levels of photosynthesis and calcification. All three of these factors vary between coccolithophore species, and with response to the growth environment. Here, water samples were collected in the northern basin of the South China Sea (SCS) during summer 2014 in order to examine how environmental variability influenced species composition and cellular levels of calcite content. The vertical structure of the coccolithophore community was strongly regulated by mesoscale eddies. All living coccolithophores produced within the euphotic zone (1 % of surface irradiance), and Florisphaera profunda was a substantial coccolithophore and coccolith-calcite producer in the Deep Chlorophyll-a Maximum (DCM), especially in most oligotrophic anti-cyclonic eddy centers. Placolith-bearing coccolithophores, plus F. profunda, and other larger and numerically rare species made almost equal contributions to coccolith-based calcite in the water column. For Emiliania huxleyi biometry measurements, coccolith size positively correlated with nutrients, and it is suggested that coccolith length is influenced by nutrient and light related growth rates. However, larger sized coccoliths were related to low pH and calcite saturation, although it is not a simple cause and effect relationship. Genotypic or ecophenotypic variation may also be linked to coccolith size variation.
