Covid-19: quando la distanza è spazio di relazione
2022
The third session of the INU 2020 conference “Post-pandemic Cities. The challenges of urban planning after the emergency” is dedicated to the new possible urban models that the pandemic led us to consider in the search for a difficult compromise between safety, sociability and a pleasant dwelling. Like a compass, the beauty guides us in achieving the social and environmental objectives that Covid-19 inexorably placed before our eyes: among these, the internal territories. Internal territories emerge as a field of experimentation of settlement structures in which wide landscape horizons prevail among the small compact villages. In 53% of Italian municipalities - equal to 60% of the national …
Analysis of the adopting process of a new retailing formule : contribution of the organizational socialisation
2013
This thesis focuses on the analysis of a retailing innovation adoption process by customers. More in particular it examines the effect of Customer Organizational Socialization on the relationship between Relational Satisfaction and Customer Loyalty to a new form of selling.Towards this end, we conducted an exploratory study to identify variables promoting the success of a retailing innovation as well as the adoption and learning processes of a new form of selling. The advantage of our approach lies not only on having surveyed various customers and non-customers groups but also on having observed employees of a "Click and Collect". The first part led to a model of the adoption of a retailing…
PRO-INNOVATION : PROCESS PRODUCTION PRODUCT
2019
The beginning of the third millennium has marked a period of unprecedented change for cities, architecture and product/visual design. Over the last two decades, economic, social and environmental causes have stimulated and conditioned research and production, directing them towards substantial paradigm changes, proposing new challenges to create more smart, more resilient, more responsive and adaptive, more efficient and more sustainable urban systems, buildings and objects – from nearly Zero Energy Buildings (nZEB) to Positive Energy Architecture (PEA) – designed and built faster, with lower costs and with a positive effect on the environment, society, health and productivity: more innovat…
Mixed component metal-organic frameworks: Heterogeneity andcomplexity at the service of application performances
2022
The synthesis of mixed-component metal-organic frameworks (MOFs) –including multivariate MOFs (MTV-MOFs), multicomponent MOFs, mixed-metals MOFs and mixed-ligands and metals MOFs– is becoming a very active research field. This is mainly based on the unique possibilities these materials offer to incorporate multiple functionalities and in how this heterogenity and complexity is translated in unexpected properties, which are not just the sum of each component. This review critically encompasses the progress made in this field, covering the synthetic approaches, and specially focusing on the current reported applications –such as gas storage and separation, catalysis, luminescence, conductivit…
Application of action camera video for fast and low-cost photogrammetric survey of cultural heritage
2022
Abstract. The research work focuses on the growing of fast and low-cost data surveying methods (both in the acquisition and processing phases), to be used mainly as a support for the management and enhancement of architectural heritage. Attention is paid on the diffusion of action cameras, characterized by wide-angle lenses and 4K video shooting, with more and more affordable prices and on the elaboration of the data with photogrammetry software. The high-resolution videos captured by these tools, in fact, allow the selection of frames characterized by sufficient overlap, necessary for point cloud generation through Structure for Motion (SfM) processes. The focus is on indoor environment ch…
Improving Web Prefetching by Making Predictions at Prefetch
2007
Most of the research attempts to improve Web prefetching techniques have focused on the prediction algorithm with the objective of increasing its precision or, in the best case, to reduce the user's perceived latency. In contrast, to improve prefetching performance, this work concentrates in the prefetching engine and proposes the Prediction at Prefetch (P@P) technique. This paper explains how a prefetching technique can be extended to include our P@P proposal on real world conditions without changes in the web architecture or HTTP protocol. To show how this proposal can improve prefetching performance an extensive performance evaluation study has been done and the results show that P@P can…
Architectural improvements and FPGA implementation of a multimodel neuroprocessor
2003
Since neural networks (NNs) require an enormous amount of learning time, various kinds of dedicated parallel computers have been developed. In the paper a 2-D systolic array (SA) of dedicated processing elements (PEs) also called systolic cells (SCs) is presented as the heart of a multimodel neural-network accelerator. The instruction set of the SA allows the implementation of several neural algorithms, including error back propagation and a self organizing feature map algorithm. Several special architectural facilities are presented in the paper in order to improve the 2-D SA performance. A swapping mechanism of the weight matrix allows the implementation of NNs larger than 2-D SA. A systo…
Bit-Parallel Approximate Pattern Matching on the Xeon Phi Coprocessor
2014
Bit-parallel pattern matching encodes calculated values in bit arrays. This approach gains its efficiency by performing multiple updates within a machine word. An important parameter is therefore the machine word size (e.g. 32 or 64 bits). With the increasing length of vector registers, the efficient mapping of bit-parallel pattern matching algorithms onto modern high performance computing architectures is becoming increasingly important. In this paper, we investigate an efficient implementation of the Wu-Manber approximate pattern matching algorithm on the Intel Xeon Phi coprocessor. This architecture features a 512-bit long vector processing unit (VPU) as well as a large number of process…
Design methods of multithreaded architectures for multicore microcontrollers
2011
The development of electronic technology today has allowed the implementation of complex architectures, which led to the emergence of multicore processors technology. Multicore architectures are built from superscalar and multithreaded processors. Integrating new technologies in embedded applications requires the development of multicore processors that can be integrated into a smaller area like a classic microcontroller. These processors must manage fewer resources and be able to manage multiple tasks simultaneously. In this paper we present a method of modeling, simulation and evaluation of two multithreaded architectures with limited resources, which could be integrated into embedded sys…
Exploiting selective instruction reuse and value prediction in a superscalar architecture
2009
In our previously published research we discovered some very difficult to predict branches, called unbiased branches. Since the overall performance of modern processors is seriously affected by misprediction recovery, especially these difficult branches represent a source of important performance penalties. Our statistics show that about 28% of branches are dependent on critical Load instructions. Moreover, 5.61% of branches are unbiased and depend on critical Loads, too. In the same way, about 21% of branches depend on MUL/DIV instructions whereas 3.76% are unbiased and depend on MUL/DIV instructions. These dependences involve high-penalty mispredictions becoming serious performance obstac…
