On Mining Dynamic Graphs for k Shortest Paths
No full textMining graphs, upon query, for k shortest paths between vertex pairs is a prominent primitive to support several analytics tasks on complex networked datasets. The state-of-the-art method to implement this primitive is kPll, a framework that provides very fast query answering, even for large inputs and volumes of queries, by pre-computing and exploiting an appropriate index of the graph. However, if the graph's topology undergoes changes over time, such index might become obsolete and thus yield incorrect query results. Re-building the index from scratch, upon every modification, induces unsustainable time overheads, incompatible with applications using k shortest paths for analytics purposes. Motivated by this limitation, in this paper, we introduce decKpll, the first dynamic algorithm to maintain a kPll index under decremental modifications. We assess the effectiveness and scalability of our algorithm through extensive experimentation and show it updates kPll indices orders of magnitude faster than the re-computation from scratch, while preserving its compactness and query performance. We also combine decKpll with incKpll, the only known dynamic algorithm to maintain a kPll index under incremental modifications, and hence showcase, on real-world datasets, the first method to support fast extraction of k shortest paths from graphs that evolve by arbitrary topological changes
Sustainable Procedures for the Recycling of Waste Building Materials: The Creative Recycling of Window Frames
Get PDFUpcycling is identified as a process of the transformation of waste materials to which it is possible to give a value of artistic or environmental quality. To date, the greatest use of upcycling can be found in the design, art and fashion sectors. As in other sectors, one of the biggest challenges in the construction industry in the future is the search for
new ways to reuse discarded materials. In this sense, upcycling is a new technique for the recovery of removed waste but with a much lower use of energy and resources than the regeneration of recycled material. With respect to these issues, the aim of this paper is to present the results of a design experimentation aimed at defining methodologies and tools for the reuse of building components from the decommissioning or renovation processes of existing buildings, with an approach that integrates both the disassembling and the reassembling of construction elements, in line with the sustainable development and climate neutrality goals that the European Union aims to achieve by 2050. The methodology used made use of a field experiment by means of the creation of a prototype that made it possible
to evaluate the results of the study which, if on the one hand made it possible to define an appropriate procedure for upcycling, on the other hand highlighted how these procedures save energy and reduce the emission of CO2 in the environment. In this specific case, the experimentation gave the following results: energy savings 2038.92 kWh; CO2 reduction 641.80 kg compared to a similar intervention from scratch. Therefore, the definition of a replicable and scalable operational process for the upcycling activity applied to architecture allows, by means of the reuse of those building materials and construction elements that still have a useful life, and which can, therefore, be used in the field of architecture, for a profitable contribution to the development of sustainable procedures in the field of
architecture and the circular economy
The regeneration of minor centres: from planning scenarios to project practices
No full textMinor historic centres in Italy represent a widespread heritage that, already recognized as a repository of historical and cultural values, seems to express today under the new paradigms of sustainability and resilience a potential that can be activated through compatible regeneration processes. The aim of the research, carried out in an interdisciplinary perspective and according to a cross-scale approach, is to define an operative tool to support the policymaking, planning and intervention actions, by local authorities and stakeholders, for regenerative processes capable of combining the heritage preservation with cultural and economic enhancement of the area, tourism promotion with natural resources protection. This paper, considering the first outcomes of the research, proposes a critical overview on the current Italian cultural, regulatory, and strategic framework on the topic of regeneration of minor centres from which a significant divergence between implementation policies and practices seems to emerge. To outline this framework, the research was divided into three phases. The first involved the selection and critical analysis of the main European and national policy documents, regulatory references and ongoing programs. The second surveyed the results of the "Village Attractiveness" initiative, funded by the Ministry of Culture for the National Recovery and Resilience Plan, which is nowadays the main source of funding for regeneration projects in minor centres. In the third phase, the contents of some projects, selected by appropriate parameters, were analysed and collected to build a database. Two significant issues seem to emerge from the research on current regeneration practices - the lack of a long-term vision in planning and the fragmentation of interventions - which lead back to the need to define an operative tool for controlling the regenerative process that is sustainable and respectful of the peculiarities of the investigated heritage
A Fully Integrated CMOS 0.3 V 335 nW PWM-Based Light-to-Digital Converter for Optoelectronic Sensing Systems in Biomedical Applications
Get PDFThis paper reports on the design of a novel, fully integrated stand-alone light-to-digital converter for optoelectronic sensors in wearable/implantable biomedical applications. The architecture designed in TSMC 180 nm standard Si CMOS technology integrates a Si photodiode, a ring oscillator, two digital counters, and a voltage-to-pulse-width modulation stage as the basic block of the light-to-digital converter in a Si area of 0.018 mm2. The modulation stage, composed of ten transistors and a capacitor, provides a square waveform whose pulse width varies as a function of its input voltage provided by the Si photodiode operating in a photovoltaic mode that linearly depends on the light intensity impinging on its sensitive area. The value of the pulse width is digitalized by two digital counters driven by the ring oscillator. The complete system, powered at 0.3 V, has been fully characterized by post-layout simulations demonstrating an overall sensitivity of 0.062 LSB/lx, a power consumption of 335 nW, and a sample rate of 3 kS/s. A comparison with similar solutions in the Literature shows that the proposed system achieves the best performance in power consumption, Si area, and supply voltage with a good sample rate value
Il piano di ammortamento “alla francese”: possibili generalizzazioni in termini di dinamica dell’importo delle rate di ammortamento. Parte II: estensione al regime finanziario della capitalizzazione semplice
No full textNEl presente studio è stato affrontato il caso di adozione del regime finanziario della capitalizzazione semplice, le cui leggi
finanziarie non godono della proprietà di scindibilità secondo Francesco Paolo Cantelli,
ma, nell’ipotesi di epoca unica di equivalenza finanziaria, godono della proprietà di scindibilità parametrica secondo Filadelfo Insolera, ipotizzando che l’operazione sia
caratterizzata da un TANm
(Tasso Annuo Nominale con convertibilità m) e quindi da
un TPE (Tasso Periodale Effettivo). I tassi periodali effettivi impliciti nei fattori di attualizzazione rappresentano tassi (medi) “a pronti”, necessari per le attualizzazioni al tempo
iniziale 0 degli importi delle rate collocati temporalmente ai tempi k (k=1,2,..,n).
Come già detto, se si vuole effettuare la stesura del piano di ammortamento dell’operazione
di prestito bisogna disporre anche dei coerenti tassi “a termine”, necessari per il calcolo
delle quote interessi; conoscendo l’importo delle rate e tali quote interessi, sarà possibile
completare il piano di ammortamento, nelle sue altre componenti (quote capitali e debiti residui)
Gradings and graded linear maps on algebras
No full textLet A be a superalgebra over a field F of characteristic zero. We prove tight relations between graded automorphisms, pseudoautomorphisms, superautomorphisms and K-gradings on A, where K is the Klein group. Moreover, we investigate the consequences of such connections within the theory of polynomial identities. In the second part we focus on the superalgebra UTn (F) of n × upper triangular matrices by completely classifying the graded-pseudo-super automorphism that one can define on it. Finally, we compute the ideals of identities of UTn endowed with a graded or a pseudo automorphism, for any n, and the ideals of identities with superautomorphism in the cases n = 2 {n=2} and n = 3 {n=3}
Regularization by rough Kraichnan noise for the generalised SQG equations
No full textWe consider the generalised Surface Quasi-Geostrophic (gSQG) equations in
with parameter , an active scalar model
interpolating between SQG () and the 2D Euler equations () in
vorticity form. Existence of weak -valued solutions in the
deterministic setting is known, but their uniqueness is open. We show that the
addition of a rough Stratonovich transport noise of Kraichnan type regularizes
the PDE, providing strong existence and pathwise uniqueness of solutions for
initial data , for suitable values
related to the regularity degree of the noise and the singularity
degree of the velocity field; in particular, we can cover any for suitable and and we can reach a suitable ("critical")
threshold. The result also holds in the presence of external forcing and solutions are shown to depend continuously on the data
of the problem; furthermore, they are well approximated by vanishing viscosity
and regular approximations
A hemivariational damageable elastoplastic vertex-spring model for masonry analysis
No full textThis work is an intermediate step towards the extension of a recently proposed block-based model for masonry structures, which was based on a hemivariational approach and inspired from granular micromechanics. Here, contrarily to the previous model, plastic effects will also be taken into account along with damage and elastic behaviours, and the full hemivariational derivation of the strong-form (in)equations will be detailed for the case of a lone vertex spring. The resulting model and methods shall then be used in future works to enrich the behaviours modelled by the previously mentioned masonry model
