Approximation Properties of the Modified Stancu Operators
2017
ABSTRACTIn this article we construct a sequence of Stancu-type operators that are based on a function τ. This function is any function on [0,1] continuously differentiable ∞ times, such that τ(0) =...
The expansion $\star$ mod $\bar{o}(\hbar^4)$ and computer-assisted proof schemes in the Kontsevich deformation quantization
2019
The Kontsevich deformation quantization combines Poisson dynamics, noncommutative geometry, number theory, and calculus of oriented graphs. To manage the algebra and differential calculus of series of weighted graphs, we present software modules: these allow generating the Kontsevich graphs, expanding the noncommutative & x22c6;-product by using a priori undetermined coefficients, and deriving linear relations between the weights of graphs. Throughout this text we illustrate the assembly of the Kontsevich & x22c6;-product up to order 4 in the deformation parameter Already at this stage, the & x22c6;-product involves hundreds of graphs; expressing all their coefficients via 149 w…
Process reference frameworks as institutional arrangements for digital service innovation
2020
Abstract Information systems (IS) service organizations are increasingly more concerned with their ability to co-create digital services with customers in service ecosystems. Practitioners and researchers, however, lack understanding of which organization mechanisms effectively contribute to IS organizations’ innovation practices. Grounded in service-dominant logic, we hypothesized that process reference frameworks (PRFs), such as the IT Infrastructure Library (ITIL), act as institutional arrangements through their norms, rules, and practices, enhancing IS organizations’ ability to innovate digital services. Data collected from 159 IS organizations confirmed our hypotheses, showing that eff…
A combined fuzzy-SEM evaluation approach to identify the key drivers of the academic library service quality in the digital technology era: An empiri…
2017
A conceptual model of the Academic Library (AL) service quality is hypothesized in the present article, and then validated and analyzed by a novel evaluation approach. Specifically, the conceptual model integrates the fundamental attributes of the canonical AL service together with those more relevant of the new and widely considered AL Electronic Service (e-services). As concerns the evaluation approach, it incorporates the Fuzzy Sets Theory (FST) so as to deal with the students' uncertainty over their own judgments on the AL service quality and a Structural Equation Model (SEM) to validate the conceptual model and to determine the key drivers of the AL service quality. The effectiveness o…
Interactive Gradually Generating Relevance Query Refinement Under the Human-Mediated Scenario in Multilingual Settings
2016
As opposed to query modelling, relevance generating interactive query refinement (QR) is a technique aimed at exploiting syntax variations of gradually extended, being removed or replaced with some other keywords query, which depending on the factors like e.g. the information resource, the database structure, or the keyword alignment, facilitates significantly the searching process. Therefore our motivation is to explore the dynamism of the precision trend depended upon the factors analyzed. For a couple of language pairs which constitute multilingual settings, we develop a user-centred framework that imposes distributed search optimization. Our data set contains variety of query types subm…
A nicely behaved singular integral on a purely unrectifiable set
2001
We construct an example of a purely 1-unrectifiable AD-regular set E in the plane such that the limit
Left-to-right tree pattern matching
1991
We propose a new technique to construct left-to-right matching automata for trees. Our method is based on the novel concept of prefix unifcation which is used to compute a certain closure of the pattern set. From the closure a kind of deterministic matching automaton can be derived immediately. We also point out how to perform the construction incrementally which makes our approach suitable for applications in which pattern sets change dynamically, such as in the Knuth-Bendix completion algorithm.
Beppe Chia and Chialab, 彼普·嘉 / Beppe Chia and Chialab, vision of graphics
2010
当Beppe Chia把研究建立在八十年代中期附近 的时候，他也许没想到，自己研究成果的规模和 重要性会随着时间的推移而被放大，但或许他那 时已经有所察觉了，因为他选择了Chialab这条 标签，他把自己对图像的观点与对合作的理解结 合在一起，在实验室、锻造车间以及分享观点和 主意的地方，以各种方式加以考虑。在古老的博 洛尼亚镇中心附近有一所超出他预想的地板房， 透过一扇玻璃舷窗，这所房子的门总是向外面敞 开着，你会发现自己完全陷入这些环境中，把自 己置身于不同的高度，完全不需要出入口。他们 聚集在一起，共同投身于书籍、研究、设计、讨 论、摄影、烹饪和食物的消耗。这些相同的场所 仅仅是一个人们可以围坐在大桌子周围的地方或 是一个小型的内部花园。我正在描绘一个地方， 原先是一间老厂房，能在这里，在Chialab这个视 觉交流的地方工作，产生出大量的想法，并可以 When Beppe Chia founds his study around the half of the eighties, he does not imagine perhaps the dimensions and the importance which it will assume as time goes on or maybe he knows, because the label that he chooses, Chialab, puts together his own views of graphics and what he thinks of teamwork, which is consi…
From the-book to the city. Public libraries' urban role in contemporary city
2013
The individualistic tendencies of contemporary society caused by the new forms of capitalism and the dematerialization of information sources have produced a progressive reduction of collective places in our cities. The square (la Piazza) is from immemorial time the heart of the historical city: a place that citizens have chosen for their leisure and encounters, for trade and exchanges. Today, such social gathering places, are progressively disappearing, replaced by centers for business and entertainment to which, in various ways, are increasingly delegated for the management and planning of the inhabitants leisure time. The question becomes an emergency when we realize that everything with…
I Vari componenti d'architettura (1766) di Michele Vella
2013
Michele Vella, sculptor and antiquarian of Agrigento, born in nearby Raffadali, is known through chronicles and accounts of foreign travelers who visited "the city of temples" duringin the last few decades of the eighteenth century. Prior to devote himself to the study of ancient Agrigento and to become a "guide" of famous visitors, such as Goethe, he began to develop a treatise on architecture dedicated in 1766 to the bishop Andrea Lucchesi Palli. The unfinished manuscript titled Vari Componimenti d'Architettura is now located at the Library Lucchesiana of Agrigento.
