Combining a context aware neural network with a denoising autoencoder for measuring string similarities
2020
Abstract Measuring similarities between strings is central for many established and fast-growing research areas, including information retrieval, biology, and natural-language processing. The traditional approach to string similarity measurements is to define a metric with respect to a word space that quantifies and sums up the differences between characters in two strings; surprisingly, these metrics have not evolved a great deal over the past few decades. Indeed, the majority of them are still based on making a simple comparison between character and character distributions without considering the words context. This paper proposes a string metric that encompasses similarities between str…
Joint Dynamic Resource Allocation for Coupled Heterogeneous Wireless Networks Based on Hopfield Neural Networks
2008
This paper proposes an algorithm to solve the problem of Joint Dynamic Resource Allocation in heterogeneous wireless networks. The algorithm is based on Hopfield Neural Networks to achieve fast and suboptimal solutions. The generic formulation is particularized and evaluated in an HSDPA and 802.11e WLAN coupled networks. Some illustrative simulations results are presented to evaluate the performance of the new algorithm as compared with other strategies. The obtained results confirm the validity of the proposal.
Two-level branch prediction using neural networks
2003
Dynamic branch prediction in high-performance processors is a specific instance of a general time series prediction problem that occurs in many areas of science. Most branch prediction research focuses on two-level adaptive branch prediction techniques, a very specific solution to the branch prediction problem. An alternative approach is to look to other application areas and fields for novel solutions to the problem. In this paper, we examine the application of neural networks to dynamic branch prediction. We retain the first level history register of conventional two-level predictors and replace the second level PHT with a neural network. Two neural networks are considered: a learning vec…
In the places of “Fragmenta”
2021
Leggere i testi, le riflessioni e le digressioni, che catturano il lettore nella loro complementarità, significa seguire “piste” di curiosità. La nuova iniziativa editoriale della Bramea Editore riflette l’intento d’interpretare il fare architettura con dei libri che guardano il campo della cultura del progetto, dell’architettura con un raggio d’azione internazionale. Ed è proprio attraverso questa unità di intenti, ravvisabile nella progettualità editoriale della Bramea, che si fondano alcuni presupposti di riconoscibilità. I testi contenuti nei libri aprono uno scenario dove si collocano i progetti e dove l’“architetto militante” è protagonista. In quest’area culturale si muove “Fragmenta…
Arturo Dazzi e Marcello Piacentini: un lungo sodalizio
2020
The paper investigates the collaboration between an artist and an architect who were among the main protagonists of the Italian cultural scene of the first half of the twentieth century: Arturo Dazzi and Marcello Piacentini. Starting from the plaster model which portrays them together and that reproduces a detail of a monumental work conceived by both between 1924 and 1931, the Arco ai Caduti of Genoa, the analysis will briefly focus on the occasions when the two characters collaborated for the realization of monumental civil and religious works until the post-war period. This case is a significant example of the conception and debate about the relationship between the figurative arts and t…
Reliģiski-filozofiski raksti, 26
2019
Volume XXVI is dedicated to the themes discussed during the scientific conference Dynamic Asia: Shaping the Future that took place in Riga on 13–15 April 2018, and were further explored after this conference. The conference was organised in cooperation between the Latvian Society for the Study of Religions and the Baltic Alliance for Asian Studies. This event brought together more than 80 participants from 20 countries. The topics presented at the conference are reflected in the current volume. Many of these articles are dedicated to Japanese culture, where spiritual, material and routine aspects intermingle in all walks of life. The Far East topic is expanded in papers on Korea and South E…
Sensitivity and mode spectrum of a frequency-output silicon pressure sensor
1988
The vibrational mode spectrum of a silicon vibrating pressure sensor is investigated. Particular attention is given to the analysis of the vibration shapes, quality factors and relative sensitivity of the resonance frequencies as a function of pressure. It is shown that a pressure sensitivity of a few parts per million at one atmosphere can be achieved. Some comments are also made regarding an improved design of the device.
Are urban water bodies really cooling?
2020
Abstract Small urban water bodies, like ponds or canals, are often assumed to cool their surroundings during hot periods, when water bodies remain cooler than air during daytime. However, during the night they may be warmer. Sufficient fetch is required for thermal effects to reach a height of 1–2 m, relevant for humans. In the ‘Really cooling water bodies in cities’ (REALCOOL) project thermal effects of typical Dutch urban water bodies were explored, using ENVI-met 4.1.3. This model version enables users to specify intensity of turbulent mixing and light absorption of the water, offering improved water temperature simulations. Local thermal effects near individual water bodies were assesse…
Analysis of the impact of intermittent distribution by modelling the network-filling process
2010
In many countries, users acquire private tanks to reduce their vulnerability to water scarcity. In such conditions, water managers often apply intermittent distribution in order to reduce the water volumes supplied to the users. This practice modifies the hydraulic behaviour of the network and determines competition among users that need to collect enough water resource for their uses. Intermittent distribution is thus responsible for the inequality that can occur among users: those located in advantaged positions of the network are able to obtain water resources soon after the service period begins, while others have to wait much longer, after the network is full. This paper analyses the i…
Pumps as turbines (PATs) in water distribution networks affected by intermittent service
2013
A hydraulic model was developed in order to evaluate the potential energy recovery from the use of centrifugal pumps as turbines (PATs) in a water distribution network characterized by the presence of private tanks. The model integrates the Global Gradient Algorithm (GGA), with a pressure-driven model that permits a more realistic representation of the influence on the network behaviour of the private tanks filling and emptying. The model was applied to a real case study: a District Metered Area in Palermo (Italy). Three different scenarios were analysed and compared with a baseline scenario (Scenario 0 – no PAT installed) to identify the system configuration with added PATs that permits th…
