description: Phase change memory (PCM) is a promising technology that can offer higher capacity than DRAM. Unfortunately, PCM's access latency and energy are higher than DRAM's and its endurance is lower. Many DRAM-PCM hybrid memory systems use DRAM as a cache to PCM, to achieve the low access latency and energy, and high endurance of DRAM, while taking advantage of PCM's large capacity. A key question is what data to cache in DRAM to best exploit the advantages of each technology while avoiding its disadvantages as much as possible. We propose a new caching policy that improveshybrid memory performance and energy efficiency. Our observation is that both DRAM and PCM banks employ row buffers that act as a cache for the most recently accessed memory row. Accesses that are row buffer hits incur similar latencies (and energy consumption) in DRAM and PCM, whereas accesses that are row buffer misses incur longer latencies (and higher energy consumption) in PCM. To exploit this, we devise a policy that avoids accessing in PCM data that frequently causes row buffermisses because such accesses are costly in terms of both latency and energy. Our policy tracks therow buffer miss counts of recently used rows in PCM, and caches in DRAM the rows that are predicted to incur frequent row buffer misses. Our proposed caching policy also takes into account the high write latencies of PCM, in addition to row buffer locality. Compared to a conventional DRAM-PCM hybridmemory system, our row buffer locality-aware caching policy improves system performance by 14% and energy efficiency by 10% on data-intensive server and cloud-type workloads. The proposed policyachieves 31% performance gain over an all-PCM memory system, and comes within 29% of the performance of an allDRAM memory system (not taking PCM's capacity benefit into account) on evaluated workloads.

description: Cool subdwarfs are the oldest members of the low mass stellar population. Mostly present in the galactic halo, subdwarfs are characterized by their low metallicity. Measuring their binary fraction and comparing it to solar metallicity stars could give key insights into the star formation process early in the history of the Milky Way. However, because of their low luminosity and relative rarity in the solar neighborhood, binarity surveys of cool subdwarfs have suffered from small sample sizes and incompleteness. Previous surveys have suggested that the binary fraction of red subdwarfs is much lower than for their main sequence cousins. Using the highly efficient RoboAO system, we present the largest yet high-resolution survey of subdwarfs, sensitive to angular separations, down to 0.15 arcsec, and contrast ratios, up to 6 magnitude difference, invisible in past surveys. Of 344 target cool subdwarfs, 40 are in multiple systems, 16 newly discovered, for a binary fraction of 11.6 percent and 1.8 percent error. We also discovered 6 triple star systems for a triplet fraction of 1.7 percent and 0.7 percent error. Comparisons to similar surveys of solar metallicity dwarf stars gives a 3 sigma disparity in luminosity between companion stars, with subdwarfs displaying a shortage of low contrast companions.

description: We consider the problem of signal recovery on graphs. Graphs model data with complex structure assignals on a graph. Graph signal recovery recovers one or multiple smooth graph signals from noisy, corrupted, or incomplete measurements. We formulate graph signal recovery as an optimization problem, for which we provide a general solution through the alternating direction methods of multipliers. We show how signal inpainting, matrix completion, robust principal component analysis, and anomaly detection all relate to graph signal recovery and provide corresponding specific solutions and theoretical analysis. We validate the proposed methods on real-world recovery problems, including online blog classification, bridge condition identification, temperature estimation, recommender system for jokes, and expert opinion combination of online blog classification.

description: We consider a Bose-Hubbard trimer, i.e. an ultracold Bose gas populating three quantum states. The latter can be either different sites of a triple-well potential or three internal states of the atoms. The bosons can tunnel between different states with variable tunnelling strength between two of them. This will allow us to study; i) different geometrical configurations, i.e. from a closed triangle to three aligned wells and ii) a triangular configuration with a $π$-phase, i.e. by setting one of the tunnellings negative. By solving the corresponding three-site Bose-Hubbard Hamiltonian we obtain the ground state of the system as a function of the trap topology. We characterise the different ground states by means of the coherence and entanglement properties. For small repulsive interactions, fragmented condensates are found for the $π$-phase case. These are found to be robust against small variations of the tunnelling in the small interaction regime. A low-energy effective many-body Hamiltonian restricted to the degenerate manifold provides a compelling description of the $π$-phase degeneration and explains the low-energy spectrum as excitations of discrete semifluxon states.

description: Statistical models of 3D human shape and pose learned from scan databases have developed into valuable tools to solve a variety of vision and graphics problems. Unfortunately, most publicly available models are of limited expressiveness as they were learned on very small databases that hardly reflect the true variety in human body shapes. In this paper, we contribute by rebuilding a widely used statistical body representation from the largest commercially available scan database, and making the resulting model available to the community (visit http://humanshape.mpi-inf.mpg.de). As preprocessing several thousand scans for learning the model is a challenge in itself, we contribute by developing robust best practice solutions for scan alignment that quantitatively lead to the best learned models. We make implementations of these preprocessing steps also publicly available. We extensively evaluate the improved accuracy and generality of our new model, and show its improved performance for human body reconstruction from sparse input data.

description: Tendo como prerrogativa o desmascaramento da pretensão, inserida em qualquer essência fenoménica e psicológica, de afirmar-se como uma entidade autónoma, isolada e independente, como puro “em si”, e à revelação de como, contrariamente, qualquer realidade empírica tenha de tal forma uma natureza impermanente subentendendo-se como uma rede de relações e de interligações, a teoria da anatta-, juntamente coma da anicca, representam no âmbito do ensinamento budista talvez o que mais se assemelha ao conceito de askesis filosófica formulado no Ocidente por uma certa tradição de pensamento tendo como raízes Heraclito, Platão, Hegel e Nietzsche e que descobre dois de entre os mais originais intérpretes em Novalis e Pessoa. De facto, quer no primeiro quer no segundo, o filosofar configura-se como uma arte de compor e recompor-se a si mesmo, um percurso de iniciação a si que passa inexoravelmente pelo abandono da posição da própria auto-referencialidade e da aceitação ontognoseológica do outro no seio do idêntico. Mediante esta operação de descentralização, que em Pessoa começa e se dissolve no interior da estratégia estética da heteronímia, onde apalavra poética transfigura-se no interstício, na abdicação e fingimento, o sujeito descobre-se diferença e relação e é-lhe finalmente possível reconhecer-se como totalidade e de reflectir-se nela.

description: We present telescoping recursive representations for both continuous and discrete indexed noncausal Gauss-Markov random fields. Our recursions start at the boundary (for example, a hypersurface in Rd , d ≥ 1) and telescope inwards. Under appropriate conditions, the recursions for the random field are differential/difference representations driven by white noise, for which we can use standard recursive estimation algorithms, such as the Kalman-Bucy filter and the Rauch-Tung-Striebel smoother.

description: The Maggiore's method (MM), which evaluates the transition frequency that appears in the adiabatic invariant from the highly damped quasinormal mode (QNM) frequencies, is used to investigate the entropy/area spectra of the Garfinkle--Horowitz--Strominger black hole (GHSBH). Instead of the ordinary QNMs, we compute the boxed QNMs (BQNMs) that are the characteristic resonance spectra of the confined scalar fields in the GHSBH geometry. For this purpose, we assume that the GHSBH has a confining cavity (mirror) placed in the vicinity of the event horizon. We then show how the complex resonant frequencies of the caged GHSBH are computed using the Bessel differential equation that arises when the scalar perturbations around the event horizon are considered. Although the entropy/area is characterized by the GHSBH parameters, their quantization is shown to be independent of those parameters. However, both spectra are equally spaced.

description: Dynamic random-access memory (DRAM) is the building block of modern main memory systems.DRAM cells must be periodically refreshed to prevent loss of data. These refresh operations waste energy and degrade system performance by interfering with memory accesses. The negative effects ofDRAM refresh increase as DRAM device capacity increases. Existing DRAM devices refresh all cells at a rate determined by the leakiest cell in the device. However, most DRAM cells can retain data for significantly longer. Therefore, many of these refreshes are unnecessary. In this paper, we proposeRAIDR (Retention-Aware Intelligent DRAM Refresh), a low-cost mechanism that can identify and skip unnecessary refreshes using knowledge of cell retention times. Our key idea is to group DRAM rows into retention time bins and apply a different refresh rate to each bin. As a result, rows containing leaky cells are refreshed as frequently as normal, while most rows are refreshed less frequently. RAIDRuses Bloom filters to efficiently implement retention time bins. RAIDR requires no modification to DRAMand minimal modification to the memory controller. In an 8-core system with 32 GB DRAM, RAIDRachieves a 74.6% refresh reduction, an average DRAM power reduction of 16.1%, and an average system performance improvement of 8.6% over existing systems, at a modest storage overhead of 1.25 KB in the memory controller. RAIDR's benefits are robust to variation in DRAM system configuration, and increase as memory capacity increases.

description: We present an efficient raycasting algorithm for rendering Volumetric Depth Images (VDIs), and we show how it can be used in a remote visualization setting with VDIs generated and streamed from a remote server. VDIs are compact view-dependent volume representations that enable interactive visualization of large volumes at high frame rates by decoupling viewpoint changes from expensive rendering calculations. However, current rendering approaches for VDIs struggle with achieving interactive frame rates at high image resolutions. Here, we exploit the properties of perspective projection to simplify intersections of rays with the view-dependent frustums in a VDI and leverage spatial smoothness in the volume data to minimize memory accesses. Benchmarks show that responsive frame rates can be achieved close to the viewpoint of generation for HD display resolutions, providing high-fidelity approximate renderings of Gigabyte-sized volumes. We also propose a method to subsample the VDI for preview rendering, maintaining high frame rates even for large viewpoint deviations. We provide our implementation as an extension of an established open-source visualization library.

Steepest-entropy-ascent quantum thermodynamic framework for describing the non-equilibrium behavior of a chemically reactive system at an atomistic level

description: Steepest-Entropy-Ascent Quantum Thermodynamics (SEAQT) provides a general framework for the description of non-equilibrium phenomena at any level, particularly the atomistic one. This theory and its dynamical postulate are used here to develop a general mathematical framework, which at an atomistic level, in particular, can be used to predict the non-equilibrium evolution in state of a closed, chemically reactive mixture such as the one examined here, i.e., a mixture of hydrogen (H2) and flourine (F) contained in an isolated tank of fixed volume. The general framework provided, however, is written for a reactive system subject to multiple reaction mechanisms. To predict this evolution in state, both the energy and particle number eigenvalue problems for a dilute gas are set up and solved analytically. Wall and non-ideal-gas behavior effects are neglected, although the extension to dense gases is straightforward but left for a future paper. The system-level energy and particle number eigenvalues and eigenstates found are used in the nonlinear equation of motion of SEAQT to determine the time evolution of the thermodynamic state of the system, thus, effectively describing the reaction kinetics of the reaction and the system's relaxation to stable equilibrium. The predicted time evolution is then compared to the results of a standard detailed kinetic model used, in the near-equilibrium limit, to extract the single time constant needed by the SEAQT equation of motion.

Measurements of the Higgs boson production cross section and couplings in the W boson pair decay channel in proton-proton collisions at $\sqrt{s}$ = 13 TeV

description: Production cross sections of the standard model Higgs boson decaying to a pair of W bosons are measured in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis targets Higgs bosons produced via gluon fusion, vector boson fusion, and in association with a W or Z boson. Candidate events are required to have at least two charged leptons and moderate missing transverse momentum, targeting events with at least one leptonically decaying W boson originating from the Higgs boson. Results are presented in the form of inclusive and differential cross sections in the simplified template cross section framework, as well as couplings of the Higgs boson to vector bosons and fermions. The data set collected by the CMS detector during 2016-2018 is used, corresponding to an integrated luminosity of 138 fb$^{-1}$. The signal strength modifier $μ$, defined as the ratio of the observed production rate in a given decay channel to the standard model expectation, is measured to be $μ$ = 0.95 $^{+0.10}_{-0.09}$. All results are found to be compatible with the standard model within the uncertainties.

description: Abnormal uterine bleeding (AUB) is a common gynaecological condition among reproductive-age patients, manifesting an ovulatory, anovulatory or anatomic pathology. The ‘see-and-treat’ approach of ambulatory hysteroscopy (AH) is a minimally invasive referral-based alternative to hysterectomy for premenopausal women. In this Quality Improvement Project (QIP), the DMAIC framework was used to analyse GP and consultant gynaecologist referrals to AH to reduce appointment wait times. Data showed that 11% of AH referrals did not attend their scheduled appointment. Also, 55% of referrals from internal consultant gynaecologists were seen within 6 weeks, while just 31% of referrals from GPs were seen within the same period. Moreover, 58% of the 90 premenopausal AH referrals were consulted about the Mirena LNG-IUS for treating AUB. 34% of these attendees did not meet the recommended treatment criteria for AH referral and 33% were prescribed neither an IUCD nor medications to treat their complaint. Furthermore, 38% of unnecessary referrals had same day IUCD insertion, a procedure that could have taken place within the primary care setting. This project identified three paths of improvement for the AH service including updated guidelines, ensuring referral meet the triage criteria and review of AH wait lists against referral criteria. Such improvements should reduce wait times through streamlining AH waiting lists, and avoiding unnecessary wait times for these women.

description: As nanoscale lithography challenges mandate greater pattern regularity and commonality for logic and memory circuits, new opportunities are created to affordably synthesize more powerful smart memory blocks for specific applications. Leveraging the ability to embed logic inside the memory block boundary, this paper demonstrates the synthesis of smart memory architectures that exploits the inherent memory address patterns of the back projection algorithm to enable efficient image reconstruction at minimum hardware overhead. An end-to-end design framework in sub-20nm CMOS technologies was constructed for the physical synthesis of smart memories and exploration of the huge design space. The experimental results show that customizing memory for the computerized tomography parallel back projection can achieve more than 30% area and power savings with marginal sacrifice of image accuracy.

description: We combine photometry from the UDS, and CANDELS UDS and CANDELS GOODS-S surveys to construct the galaxy stellar mass function probing both the low and high mass end accurately in the redshift range 0.3 26.0), affording us robust measures of structural parameters. We construct stellar mass functions for the entire sample as parameterised by the Schechter function, and find that there is a decline in the values of phi and of alpha with higher redshifts, and a nearly constant M* up to z~3. We divide the galaxy stellar mass function by colour, structure, and environment and explore the links between environmental over-density, morphology, and the quenching of star formation. We find that a double Schechter function describes galaxies with high Sersic index (n>2.5), similar to galaxies which are red or passive. The low-mass end of the n>2.5 stellar mass function is dominated by blue galaxies, whereas the high-mass end is dominated by red galaxies. This hints that possible links between morphological evolution and star formation quenching are only present in high-mass galaxies. This is turn suggests that there are strong mass dependent quenching mechanisms. In addition, we find that the number density of high mass systems is elevated in dense environments, suggesting that an environmental process is building up massive galaxies quicker in over densities than in lower densities.

Por um lado, enquanto análise do pessimismo, diagnostica ou adivinha um “nirvana” nacional. Por outro lado, parece anunciar, ainda que de forma negativa, uma linha do pensamentoe da cultura portuguesa que se debruçou sobre o Oriente e o Budismo.

Search for resonant and nonresonant production of pairs of dijet resonances in proton-proton collisions at $\sqrt{s}$ = 13 TeV

Year: 2022
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for pairs of dijet resonances with the same mass is conducted in final states with at least four jets. Results are presented separately for the case where the four jet production proceeds via an intermediate resonant state and for nonresonant production. The search uses a data sample corresponding to an integrated luminosity of 138 fb$^{-1}$ collected by the CMS detector in proton-proton collisions at $\sqrt{s}$ = 13 TeV. Model-independent limits, at 95% confidence level, are reported on the production cross section of four-jet and dijet resonances. These first LHC limits on resonant pair production of dijet resonances via high mass intermediate states are applied to a signal model of diquarks that decay into pairs of vector-like quarks, excluding diquark masses below 7.6 TeV for a particular model scenario. There are two events in the tails of the distributions, each with a four-jet mass of 8 TeV and an average dijet mass of 2 TeV, resulting in local and global significances of 3.9 and 1.6 standard deviations, respectively, if interpreted as a signal. The nonresonant search excludes pair production of top squarks with masses between 0.50 TeV to 0.77 TeV, with the exception of a small interval between 0.52 and 0.58 TeV, for supersymmetric $R$-parity-violating decays to quark pairs, significantly extending previous limits. Here, the most significant excess above the predicted background occurs at an average dijet mass of 0.95 TeV, for which the local and global significances are 3.6 and 2.5 standard deviations, respectively.

description: The vast number of security incidents are caused by exploits against vulnerabilities for which a patch is already available, but that users simply did not install. Patch installation is often delayed because patches must be tested manually to make sure they do not introduce problems, especially at the enterprise level.
In this paper we propose a new tandem execution approach for automated patch testing. Our approach is based on a patch execution consistency model which maintains that a patch is safe to apply if the executions of the pre and post-patch program only differ on attack inputs. Tandem execution runs both pre and postpatch programs simultaneously in order to check for execution consistency. We have implemented our techniques in TACHYON, a system for online patch testing in Linux. TACHYON is able to automatically check and verify patches without source access.

description: We consider binary systematic network codes and investigate their capability of decoding a source message either in full or in part. We carry out a probability analysis, derive closed-form expressions for the decoding probability and show that systematic network coding outperforms conventional network coding. We also develop an algorithm based on Gaussian elimination that allows progressive decoding of source packets. Simulation results show that the proposed decoding algorithm can achieve the theoretical optimal performance. Furthermore, we demonstrate that systematic network codes equipped with the proposed algorithm are good candidates for progressive packet recovery owing to their overall decoding delay characteristics.

A figuração prometéica do humano em Basílio Teles: figuração protobudista?
Creators: name: Epifânio, Renato
Publisher: name: Revista Lusófona de Ciência das Religiões
Year: 2013

description: Neste texto, o nosso principal propósito foi o de reflectir sobre a visão de Basílio Teles humano e, ao mesmo tempo, a sua perspectiva do divino. Como veremos, a sua perspectiva do divino não é “transcendentalista”. Mas, poderá ser, por essa razão, “budista”? Essa será a questão à qual procuraremos responder.

A visão do Budismo em Eça de Queirós
Creators: name: Real, Miguel
Publisher: name: Revista Lusófona de Ciência das Religiões
Year: 2013

description: Eça sui pde Queirós não possui um texto reflexivo sobre o budismo, nem a sua obra pos-personagens budistas. A sua concepção da doutrina de Buda e do budismo surge,em essência, no romance A Correspondência de Fradique Mendes, texto da última fase da obra de Eça de Queirós, e obedece ao espírito humanista presente nos romances e contos publicados ou escritos nos seus últimos dez anos de vida (1890 – 1900). Usando uma metodologia comparatista, Eça faz equivaler Buda a Cristo como homens santos, o pri- meiro para a mentalidade oriental, o segundo para a ocidental. No entanto, porque Buda permite a salvação de todos através do aperfeiçoamento das diversas reencarnações corporais, Fradique prefere Buda a Cristo.

description: We evaluate the smoothed first moment of central values of a family of qudratic Hecke $L$-functions in the Gaussian field using the method of double Dirichlet series. The asymptotic formula we obtain has an error term of size $O(X^{1/4+\varepsilon})$ under the generalized Riemann hypothesis. The same approach also allows us to obtain asymptotic formulas for all $X$, $Y$ for a smoothed double character sum involving $\sum_{N(m) \leq X, N(n)\leq Y}\left( \frac{m}{n} \right)$, where $\left( \frac{\cdot}{n} \right)$ denotes the quadratic symbol in the Gaussian field.

Antero de Quental foi budista?

Year: 2013

description: A meditação em torno do Budismo é o centro da articulação da vida filosófica de Antero de Quental. Tendo partido de uma visão pessimista e nihilista do Budismo, Antero foi-se aproximando duma visão do Budismo, histórica e culturalmente bem alicerçada, que lhe permitiu encontrar a via para a solução das aporias da Civilização Ocidental. A constatação deste facto impõe uma visão renovada do pensamento de Antero, quer ao nível da especulação filosófica (de que se ocupa este texto), quer ao nível da meditação poética.

description: Topological photonic states, inspired by robust chiral edge states in topological insulators, have recently been demonstrated in a few photonic systems, including an array of coupled on-chip ring resonators at communication wavelengths. However, the intrinsic difference between electrons and photons determines that the topological protection in time-reversal-invariant photonic systems does not share the same robustness as its counterpart in electronic topological insulators. Here, in a designer surface plasmon platform consisting of tunable metallic sub-wavelength structures, we construct photonic topological edge states and probe their robustness against a variety of defect classes, including some common time-reversal-invariant photonic defects that can break the topological protection, but do not exist in electronic topological insulators. This is also the first experimental realization of anomalous Floquet topological edge states, whose topological phase cannot be predicted by the usual Chern number topological invariants.

description: The capacity and cost-per-bit of DRAM have historically scaled to satisfy the needs of increasingly large and complex computer systems. However, DRAM latency has remained almost constant, making memory latency the performance bottleneck in today's systems. We observe that the high accesslatency is not intrinsic to DRAM, but a trade-off made to decrease cost-per-bit. To mitigate the high area overhead of DRAM sensing structures, commodity DRAMs connect many DRAM cells to each sense-amplifier through a wire called a bitline. These bitlines have a high parasitic capacitance due to their long length, and this bitline capacitance is the dominant source of DRAM latency. Specialized low-latency DRAMs use shorter bitlines with fewer cells, but have a higher cost-per-bit due to greater sense-amplifier area overhead. In this work, we introduce Tiered-Latency DRAM (TL-DRAM), which achieves both low latency and low cost-per-bit. In TL-DRAM, each long bitline is split into two shorter segments by an isolation transistor, allowing one segment to be accessed with the latency of a short-bitline DRAM without incurring high cost-per-bit. We propose mechanisms that use the low-latencysegment as a hardware-managed or software-managed cache. Evaluations show that our proposed mechanisms improve both performance and energy-efficiency for both single-core and multi-programmed workloads.
Caminho marítimo – O elemento oriental na cosmologia d’Os Lusíadas
Creators: name: Beato, João
Publisher: name: Revista Lusófona de Ciência das Religiões
Year: 2013

description: Acosmologia d’Os Lusíadas revela uma compreensão do Universo em que Religião,Estética e Ciência se articulam num sistema unitário, resultante da harmonização, criada por Luís de Camões, entre Paganismo e Cristianismo. Este caminho espiritual, a que atribuo o termo de desdramatização, consiste num processo da consciência em que se esbatem as oposições dualistas entre sujeito e objecto, ou seja, em que deixa de haver uma distinção dramática entre o “eu” e o “outro”: a transcendência da identificação do “eu” com o aspecto do corpo a partir do qual se constrói a persona. A superação do universo dionisíaco realizada através da relação subjectiva do ser humano com a divindade e da relação objectiva da divindade com o ser humano, relações essas mediadas pelo universo da Sensibilidade e da Criatividade. Esta forma de espiritualidade, o erotismo camoniano, terá resultado da compreensão comparada das tradições espirituais ocidentais e orientais.

title: Machine Learning und Künstliche Intelligenz im Mathematikunterricht der Sekundarstufe
Creators: name: Mölk, Eva-Theres
Year: 2023

description: Mit Künstlicher Intelligenz sind wir in unserem Alltag immer mehr und mehr konfrontiert. Sie ist eine junge wissenschaftliche Disziplin, die sich in einer rasanten Geschwindigkeit entwickelt und auf dem Weg ist, unser Leben grundlegend zu verändern. Gleichzeitig wird das Thema in der Gesellschaft kontrovers diskutiert. Im Zuge dieser Arbeit wurde untersucht, inwieweit Inhalte aus dem Gebiet des Machine Learning (ML) und der Künstlichen Intelligenz (KI), im Rahmen des aktuell gültigen Mathematiklehrplans (AHS, HTL, HAK) Anwendung im Unterricht der Sekundarstufe finden können. Diverse Anwendungen wurden auf Basis von Literaturrecherche analog sowie computerunterstützt vor allem mit Geogebra und Python vorgestellt und mit den Inhalten der Lehrpläne verglichen. Darüber hinaus wurde an manchen Stellen versucht, konkrete Anwendungsbeispiele für den Einsatz in der Schule zu entwickeln. Das Thema ist stark mit dem Einsatz von Computern verknüpft, weshalb ein Grundwissen über die Funktionsweise derselben von Seiten der Schüler*innen vorhanden sein sollte. Übereinstimmungen wurden bei den Lehrplanthemen Statistik und Wahrscheinlichkeit (Histogramme, Boxplots, Nominal- und Ordinalskalen, Lineare Abhängigkeit, Mittelwert, Standardabweichung, Lineare Regression, Interpretation von Wahrscheinlichkeiten, Bedingte Wahrscheinlichkeit), Funktionen und Differentialrechnung (Geradengleichungen, funktionale Zusammenhänge, stückweise definierte Funktionen, Polynomfunktionen, Funktionstransformationen, Ableitungen, verkettete Funktionen, partielle Ableitungen, Extremwertaufgaben, Funktionen in mehreren Veränderlichen, Korrelationskoeffizienten, Logistisches Wachstum), Vektorrechnung (Euklidische Abstände, Skalares Produkt, Normalvektorform einer Geraden) gefunden. Darüber hinaus treten iterative Prozesse und Fallunterscheidungen auf. Aufgrund der Inhalte und der Komplexität eignet sich die Behandlung von ML und KI besonders für den Unterricht in der Sekundarstufe II. Sie können sowohl in AHS als auch in BHS als Anwendungsgebiet der Mathematik vorgestellt werden. Besonders gut eignen sie sich für den Unterricht an Schulen mit einem Informatikschwerpunkt.
Erwachsenenbildung in Süd-Korea

description: The Korean education system is very strongly geared to young people: the participation of the younger generations in state and private education is above the OECD average. The picture is different for older age groups, however. In recent years Korea has developed important elements of a system of lifelong learning like the extension of the coverage offered by the Employment Insurance System, the support provided by training consortia for large, medium-sized and small companies, and a new system of certification of prior learning. It is shown in this paper that these elements are, however, (1) still insufficiently interconnected, (2) not closely linked to the employment system, (3) they do not offer the low-skilled enough opportunities for lifelong learning, and (4) the resources spent on adult education are too low. It is also shown that the highly dualistic labour market acts as an important barrier to the expansion of lifelong learning. This division in the labour market, the lack of mobility prospects for irregular workers and workers in SMEs, and the seniority-based wage system all mean that there is virtually no financial incentive for many workers to invest in their own human capital.
