Conflicting Values of Inquiry: Ideologies of Epistemology in Early Modern Europe
No full textHistorical research in previous decades has done a great deal to explore the social and political context of early modern natural and moral inquiries. Particularly since the publication of Steven Shapin and Simon Schaffer’s Leviathan and the Air-Pump (1985) several studies have attributed epistemological stances and debates to clashes of political and theological ideologies. The present volume suggests that with an awareness of this context, it is now worth turning back to questions of the epistemic content itself. The contributors to the present collection were invited to explore how certain non-epistemic values had been turned into epistemic ones, how they had an effect on epistemic content, and eventually how they became ideologies of knowledge playing various roles in inquiry and application throughout early modern Europ

Demeter: A Fast and Energy-Efficient Food Profiler Using Hyperdimensional Computing in Memory
No full textFood profiling is an essential step in any food monitoring system needed to prevent health risks and potential frauds in the food industry. Significant improvements in sequencing technologies are pushing food profiling to become the main computational bottleneck. State-of-the-art profilers are unfortunately too costly for food profiling. Our goal is to design a food profiler that solves the main limitations of existing profilers, namely (1) working on massive data structures and (2) incurring considerable data movement, for a real-time monitoring system. To this end, we propose Demeter, the first platform-independent framework for food profiling. Demeter overcomes the first limitation through the use of hyperdimensional computing (HDC) and efficiently performs the accurate few-species classification required in food profiling. We overcome the second limitation by the use of an in-memory hardware accelerator for Demeter (named Acc-Demeter) based on memristor devices. Acc-Demeter actualizes several domain-specific optimizations and exploits the inherent characteristics of memristors to improve the overall performance and energy consumption of Acc-Demeter. We compare Demeter’s accuracy with other industrial food profilers using detailed software modeling. We synthesize Acc-Demeter’s required hardware using UMC’s 65nm library by considering an accurate PCM model based on silicon-based prototypes. Our evaluations demonstrate that Acc-Demeter achieves a (1) throughput improvement of 192× and 724× and (2) memory reduction of 36× and 33× compared to Kraken2 and MetaCache (2 state-of-the-art profilers), respectively, on typical food-related databases. Demeter maintains an acceptable profiling accuracy (within 2% of existing tools) and incurs a very low area overhead.Computer EngineeringQuantum & Computer Engineerin
Development of a European Multi-Model Ensemble System for Seasonal to Inter-Annual Prediction (DEMETER)
Get PDFA multi-model ensemble-based system for seasonal-to-interannual prediction has been developed in a joint European project known as DEMETER (Development of a European Multimodel Ensemble Prediction System for Seasonal to Interannual Prediction). The DEMETER system comprises seven global atmosphere–ocean coupled models, each running from an ensemble of initial conditions. Comprehensive hindcast evaluation demonstrates the enhanced reliability and skill of the multimodel ensemble over a more conventional single-model ensemble approach. In addition, innovative examples of the application of seasonal ensemble forecasts in malaria and crop yield prediction are discussed. The strategy followed in DEMETER deals with important problems such as communication across disciplines, downscaling of climate simulations, and use of probabilistic forecast information in the applications sector, illustrating the economic value of seasonal-to-interannual prediction for society as a whole
Logarithmic L p Bounds for Maximal Directional Singular Integrals in the Plane
No full textLet K be a Calderón-Zygmund convolution kernel on R. We discuss the L p -boundedness of the maximal directional singular integral T V f(x)= sup v ε V | ∫R f(x+t v) K(t)dt|where V is a finite set of N directions. Logarithmic bounds (for 2≤p<∞) are established for a set V of arbitrary structure. Sharp bounds are proved for lacunary and Vargas sets of directions. The latter include the case of uniformly distributed directions and the finite truncations of the Cantor set. We make use of both classical harmonic analysis methods and product-BMO based time-frequency analysis techniques. As a further application of the latter, we derive an L p almost orthogonality principle for Fourier restrictions to cones. © 2012 Mathematica Josephina, Inc
ÖNTÖZÉSJELENTÉS 2021. év
Get PDFA beérkezett adatok alapján országos szinten az üzemre engedélyezett éves vízmennyiség (a halastavakkal együtt) megyénként átlagosan 29,6 millió m3 volt, de három megyében a 2 millió m3-t sem érte el: Nógrád megye (197,6 ezer m3), Veszprém megye (1703,8 ezer m3) és Vas megye (1452,9 ezer m3). A vizsgált évben, a beküldött adatok alapján a gazdálkodók (a halastavak adatai nélkül) 85 031,5 hektáron (+10 százalék) 118,4 millió m3 vizet (+35,3 százalék) öntöztek ki 2021-ben az előző évhez képest. A megöntözött terület 82,2 százaléka az Alföldön található, ahová a kiöntözött vízmennyiség 86,8 százaléka jutott.
Az adatszolgáltatók jelentései alapján hazánkban 2021-ben hektáronként átlagosan 1393 m3 vizet használtak a gazdálkodók, 23 százalékkal többet, mint 2020-ban, amennyiben öntözték a területüket. Nagy volt a szórás régiónként: a Dél-Alföldön egy hektáron átlagosan 1600 m3 vizet öntöztek ki, ami az országos átlagnál 14,9 százalékkal több, ezzel szemben Észak-Magyarországon kevesebb vizet használtak fel hektáronként, mint az országos átlag harmada.
Az öntözött terület közel kilenctizedét 2021-ben is felszíni vízzel öntözték a gazdálkodók (hasonlóan a 2020-as értékhez), és csupán 12 százalékát felszín alattival. A kiöntözött vízmennyiség kétharmadát esőztető öntözőberendezéssel juttatták ki: a teljes vízmennyiség 47,4 százalékát lineár öntözőberendezéssel, 8,8 százalékát csévélődobossal és 10,8 százalékát körforgó rendszerűvel.
------------
Based on the data received, the average annual volume of water (including fish ponds) authorised for the plant at national level was 29.6 million m3 per county, but in three counties it was less than 2 million m3: Nógrád county (197.6 thousand m3), Veszprém county (1,703.8 thousand m3) and Vas county (1,452.9 thousand m3). In the year under review, based on the data submitted, farmers (excluding the data on fish ponds) irrigated 85,031.5 hectares (+10 per cent) with 118.4 million m3 of water (+35.3 per cent) in 2021 compared to the previous year. 82.2 per cent of the irrigated area is located in the Great Plain, where 86.8 per cent of the irrigated water volume was allocated.
According to the data providers' reports, in 2021, farmers in our country used on average 1,393 m3 of water per hectare, 23 per cent more than in 2020, when irrigating their land. There was a wide variation by region: in the Southern Great Plain, an average of 1,600 m3 of water per hectare was irrigated, 14.9 per cent more than the national average, while in Northern Hungary, less than a third of the national average was used per hectare.
In 2021, farmers irrigated nearly nine-tenths of the irrigated area with surface water (similar to 2020) and only 12 per cent with subsurface water. Two thirds of the irrigated water was applied by farmers using sprinkler irrigation: 47.4 per cent of the total water was applied by linear irrigation, 8.8 per cent by coil irrigation and 10.8 per cent by recirculation

Demeter: A CASE study of software growth through parameterized classes
No full textCopyright c○1988 Karl Lieberherr The Demeter T M system is a CASE (Computer-Aided Software Engineering) tool designed for the development of large software projects using a new software design methodology which focuses on growing rather than building software. We describe the software development process as one of growth and evolution as opposed to building and rebuilding because most complex objects in the real world are grown and not built. Since software design is obviously a complex process this new paradigm may be helpful in unraveling some of the problems associated with current software design practices. Demeter begins by providing an ideal environment for the sprouting and nuturing of a seed (class dictionary) into a plant (large scale software project). In addition, through the combined use of object-oriented programming technology, and parameterized classes, Demeter provides a facility for the reuse of software which was developed in previous software projects.

Labour productivity change: drivers, business impact and macroeconomic moderators
Get PDFThis paper focuses on the operational drivers of labour productivity changes. We consider two sets of
drivers: a) current working practices b) changes in working practices through management programs.
The relationship between these two sets of drivers and productivity changes are analysed. We also
investigate the importance of productivity growth by looking at the impact of labour productivity
changes on business performance changes. Finally, the moderating effects of industry and country on
the use of drivers of productivity changes are examined. Data from an international survey, IMSS-IV,
are used for the analysis
