Logika algorytmów w świecie pracy ery technologicznej - nowe możliwości i nowe ograniczenia
2022
Uprawnienia kierownicze pracodawcy wynikające z przepisów prawa pracy są innej natury niż te kształtowane przez technologię, lokują one działanie kierownictwa pracodawcy w zupełnie innym obszarze niż technologia — w relacjach międzyludzkich, a nie w danych, w poleceniach, a nie w sygnałach, w odnoszeniu się do sposobów bycia jednostki, a nie do sprzężeń zwrotnych, do jej sumienności i staranności, a nie do nastawiania jej na wykorzystywanie. Kierownictwo technologiczne ma inne środki wyrazu, inną metodykę działania, inną skalę przymusu i porządku, jest inaczej zabezpieczane, nie zna granic, które stawia się kierownictwu normatywnemu. Technologia pozwala na zmianę paradygmatu kierownictwa dz…
Osservazioni su contratti algoritmici e tutela del consumatore nell’economia di piattaforma
2020
Il saggio prende in esame alcune delle tutele predisposte dalla direttiva 2019/2161 del Parlamento e del Consiglio in favore del consumatore, nell’ipotesi in cui quest’ultimo sia assistito, nell’incontro con il professionista, dall’uso di tecnologie computazionali: con una espressione di sintesi, l’Autore si riferisce a questa evenienza con la locuzione “contratti algoritmici”. Tre sono gli aspetti cui si dirige l’attenzione: 1) la specificità dell’economia di piattaforma, luogo privilegiato in cui gli algoritmi orientano le scelte di consumo; 2) gli algoritmi che sono adoperati nell’atto di consumo; 3) l’ottimizzazione dei prezzi tramite profilazione automatizzata, quale caso paradigmatico…
Sequential formula translation
1983
The syntax of an algorithmic language such as ALGOL is conveniently described as a sequence of states indicated by an element called cellar. Transitions are controlled by admissible state- s ymbol pairs which may be represented by a transition matrix. This description of syntax furnishes at the same time an extremely simple rule for translating into machine programs statements in the algorithmic language. Sequential treatment, however, is not feasible in the case of certain optimizing processes such as recursive address calculation.
The Coexistence of Three Species of Daphnia in the Klostersee: iii. The Simulation Model Coda
1991
The population dynamics of three coexisting Daphnia species are described by means of a discrete event simulation model. The model is formulated in the algorithmic language SIMULA which allows very convenient object-oriented programming. Different compartments of a lake are simulated at different levels of integration, each represented by a PROCESS CLASS in SIMULA: The properties of the lake are deposited in a set of meteorological data which were measured in the field. Fish are simulated as a population with properties which are derived from field observations and Daphnia are represented as individuals. The model shows that hypotheses about the stabilizing mechanisms (seasonal change of en…
Paths Coloring Algorithms in Mesh Networks
2003
In this paper, we will consider the problem of coloring directed paths on a mesh network. A natural application of this graph problem is WDM-routing in all-optical networks. Our main result is a simple 4-approximation algorithm for coloring line-column paths on a mesh. We also present sharper results when there is a restriction on the path lengths. Moreover, we show that these results can be extended to toroidal meshes and to line-column or column-line paths.
The Myriad Virtues of Suffix Trees
2006
Wavelet Trees have been introduced in [Grossi, Gupta and Vitter, SODA ’03] and have been rapidly recognized as a very flexible tool for the design of compressed full-text indexes and data compressors. Although several papers have investigated the beauty and usefulness of this data structure in the full-text indexing scenario, its impact on data compression has not been fully explored. In this paper we provide a complete theoretical analysis of a wide class of compression algorithms based on Wavelet Trees. We also show how to improve their asymp- totic performance by introducing a novel framework, called Generalized Wavelet Trees, that aims for the best combination of binary compressors (lik…
Multi-model ensemble simulations of olive pollen distribution in Europe in 2014: current status and outlook
2017
"Çalışmada 29 yazar bulunmaktadır. Bu yazarlardan sadece Bursa Uludağ Üniversitesi mensuplarının girişleri yapılmıştır” The paper presents the first modelling experiment of the European-scale olive pollen dispersion, analyses the quality of the predictions, and outlines the research needs. A 6-model strong ensemble of Copernicus Atmospheric Monitoring Service (CAMS) was run throughout the olive season of 2014, computing the olive pollen distribution. The simulations have been compared with observations in eight countries, which are members of the European Aeroallergen Network (EAN). Analysis was performed for individual models, the ensemble mean and median, and for a dynamically optimised c…
Interaction between filaggrin mutations and neonatal cat exposure in atopic dermatitis
2020
Atopic dermatitis (AD) is a prevalent inflammatory skin disease. Loss-of-function mutations in filaggrin gene (FLG) represent the strongest genetic risk factors for AD, being strongly associated with early disease onset and persistence into adulthood.1 The epidermis of individuals with mutations in FLG is fundamentally different from normal skin being characterized by increased penetration of allergens.2 Recent birth cohort studies showed a significant interaction between cat ownership at birth and mutations in FLG (R501X, 2282del4) on the development of early-onset AD.3 This finding was replicated for the 2282del4 FLG mutation in a Dutch cohort study, and extended to further associate with…
Non-chromatographic speciation
2010
We evaluate the main strategies for screening trace-element species in most types of sample to establish their strengths and weaknesses, as they offer fast, sensitive and cheaper alternatives to classical methods involving chromatography. We consider the principles of non-chromatographic speciation analysis, based on the different behaviors of chemical species before measurement by atomic and molecular spectrometry and electroanalytical methods, so as to give an update on the literature in this field of research.
Structural Reforms in Banking: The Role of Trading
2017
In the wake of the recent financial crisis, significant regulatory actions have been taken aimed at limiting risks emanating from trading in bank business models. Prominent reform proposals are the Volcker Rule in the U.S., the Vickers Report in the UK, and, based on the Liikanen proposal, the Barnier proposal in the EU. A major element of these reforms is to separate "classical" commercial banking activities from securities trading activities, notably from proprietary trading. While the reforms are at different stages of implementation, there is a strong ongoing discussion on what possible economic consequences are to be expected. The goal of this paper is to look at the alternative approa…
