CUDA-BLASTP: Accelerating BLASTP on CUDA-enabled graphics hardware
2011
Scanning protein sequence database is an often repeated task in computational biology and bioinformatics. However, scanning large protein databases, such as GenBank, with popular tools such as BLASTP requires long runtimes on sequential architectures. Due to the continuing rapid growth of sequence databases, there is a high demand to accelerate this task. In this paper, we demonstrate how GPUs, powered by the Compute Unified Device Architecture (CUDA), can be used as an efficient computational platform to accelerate the BLASTP algorithm. In order to exploit the GPU's capabilities for accelerating BLASTP, we have used a compressed deterministic finite state automaton for hit detection as wel…
The long and winding road of enterprise architecture implementation in the Finnish public sector
2018
This thesis examines the implementation of enterprise architecture (EA) in the Finnish public sector. EA is a systematic approach for analysing, visualising, developing and governing the functions and structures of organisations. It describes how organisations businesses, information and systems function as a whole. Research and practice have shown the implementation of EA is challenging and slow to advance. Finland provides a prolific area for research since the use of EA is mandatory in public sector, which is rare amongst countries taking a whole-of-government EA approach. In order to research EA as a method for systemic change, a suitable theoretical framing was necessary. The context, …
Zero-shot Semantic Segmentation using Relation Network
2021
Zero-shot learning (ZSL) is widely studied in recent years to solve the problem of lacking annotations. Currently, most studies on ZSL are for image classification and object detection. But, zero-shot semantic segmentation, pixel level classification, is still at its early stage. Therefore, this work proposes to extend a zero-shot image classification model, Relation Network (RN), to semantic segmentation tasks. We modified the structure of RN based on other state-of-the-arts semantic segmentation models (i.e. U-Net and DeepLab) and utilizes word embeddings from Caltech-UCSD Birds 200-2011 attributes and natural language processing models (i.e. word2vec and fastText). Because meta-learning …
Migrating from a Centralized Data Warehouse to a Decentralized Data Platform Architecture
2021
To an increasing degree, data is a driving force for digitization, and hence also a key asset for numerous companies. In many businesses, various sources of data exist, which are isolated from one another in different domains, across a heterogeneous application landscape. Well-known centralized solution technologies, such as data warehouses and data lakes, exist to integrate data into one system, but they do not always scale well. Therefore, robust and decentralized ways to manage data can provide the companies with better value give companies a competitive edge over a single central repository. In this paper, we address why and when a monolithic data storage should be decentralized for imp…
Exploring the Critical Success Factors in Social and Health Care Information Systems Project Procurement
2020
A welfare reform involving the mixing of social and health services is being introduced by the Finnish government. Several factors have been identified for this shift, the most relevant of which is that many information systems are not interoperable and data-related problems have been identified. Management and isolated offers of service. Digitalizing to solve these issues is part of the government’s policy. This paper outlines the change landscape and explores the architectural options of the proposed digitalisation process and crucial success factors. The Undertaking The design is applied to the largest county, which consists of over 1,900 information systems related to social support and…
Categorization of the historic architecture in Palermo for the purpose of energy assessment
2015
Il contributo espone l'applicazione al centro storico di Palermo di un metodo di "categorizzazione", sviluppato nell'ambito del progetto europeo Effesus per analizzare le prestazioni energetiche di comparti di architettura storica. Lo studio si concentra sul "mandamento" Castellammare e mira a combinare questa descrizione per categorie con l'impostazione tipologica del Piano Particolareggiato Esecutivo del centro storico. The strategies to improve the energy performance of historic buildings can be compatible with their conservation if they are referred to material, construction, distribution features, strictly related to a local level. In the EU project EFFESUS, a method of categorization …
I caratteri locali dell'architettura storica come strumento di miglioramento energetico - Improving the energy performance of historic buildings thro…
2017
Il contributo espone un metodo per definire, su specifici contesti locali, un quadro generale di conoscenze utile a migliorare le prestazioni energetiche e ambientali dell’architettura storica in modo compatibile con le esigenze di conservazione. Tale approccio si fonda sull’analisi dei caratteri ricorrenti del patrimonio storico locale alla scala del componente tecnico, dell’edificio e dell’aggregato urbano. Attraverso un’applicazione al Centro Storico di Palermo, si mostra la validità del metodo proposto nelle analisi a vasta scala, nell’elaborazione di indirizzi normativi e strategie finanziarie, nel valutare l’efficacia e la compatibilità di possibili interventi di miglioramento energet…
Edifici storici ed efficienza energetica. Palermo come scenario di sperimentazione
2017
La monografia tratta l’efficienza energetica degli edifici storici sotto due profili. A livello generale ne esamina l’intreccio con i principi della conservazione, con la disciplina del restauro, con le prescrizioni di tutela; ripercorrendo il fervente dibattito sul tema, propone una panoramica sui principali campi d’indagine della ricerca scientifica e sugli interventi di miglioramento energetico proposti per il patrimonio culturale. Delineato un quadro d’insieme, il volume si sofferma sulla ricca e variegata architettura storica di Palermo, muovendosi tra la letteratura tecnica disponibile, il Piano Particolareggiato Esecutivo e il Manuale del recupero del centro storico. L’approfondiment…
Historic additional stories in the cultural heritage of Palermo: critical analysis for the purpose of structural and energy improvement
2018
This paper analyses construction features and performances of additional storeys in historic buildings. The recurring characteristics of these historic accretions are investigated by focusing on the cultural heritage of Palermo, where the practice of extending buildings by raising new levels was widespread both in monumental and vernacular architecture, in public and private constructions. The performance deficiencies of additional storeys are examined in terms of structural safety, thermal comfort and building energy demand. On this basis, the utility of mapping these structures, their morphology and their location in the urban fabric is discussed.
Contributo alla conoscenza delle proprietà termofisiche delle murature storiche palermitane
2014
This paper presents the preliminary findings of in situ measurements of thermal transmittance taken in a monumental complex in Palermo. The objective of energy efficiency, one of the main aspects of sustainable construction, is now relevant also for historic architecture. The research aims at analysing the energy performance of the stone walls of the complex, characterized by various thickness, age and construction features. Measurements are taken in accordance with the international standard ISO 9869:1994. The U-values so obtained are compared with tabular data from the Italian standard UNI/TS 11300-1:2008 and with values calculated following the UNI EN ISO 6946:2008. Nine preliminary meas…
