Development of artificial neural network for condition assessment of bridges based on hybrid decision making method – Feasibility study
2021
Abstract Managing a bridge at an appropriate level of reliability requires knowledge of its technical condition, which is decisive in terms of maintenance and repair activities. This is a multi-criteria decision-making problem which results from the need to allocate limited financial resources to this work. Although many calculation models have been suggested in published sources, none of them has ever met these requirements. The algorithm presented by the authors allows for the assessment of any number of bridges, taking into account the diversity of solutions in terms of materials and structures, and can provide a solution to this problem. This hybrid calculation model, combining the modi…
A Hybrid AHP Approach and GIS-Based Methods as Fundamental Tools in the SECAP’s Decision-Making Process
2023
Adapting to climate change and mitigating its impacts are the main challenges for cities today. One objective that the European Commission has set in recent decades is reducing climate change inaction, and several political actions have been implemented. Among these actions, the Covenant of Mayors led to the development and adoption of Sustainable Energy and Climate Action Plans (SECAPs) by many cities worldwide. A challenge that local authorities must face during the development of a SECAP is the identification of the policies to be included in the plan. This paper presents a case study to show the validity of using a hybrid analytic hierarchy process (AHP) approach and various geographic …
A composite indicator index as a proxy for measuring the quality of water supply as perceived by users for urban water services
2021
Abstract The objective of this study is to develop a composite indicator (CI) to measure the quality of water supply based on the variables that are considered to affect users’ perceptions of water supply quality. The proposed CI includes six relevant aspects that determine users’ perceptions of water supply quality (network quality, water quality, water price, complaints, inconvenience caused by upgrading the network, and continuity of service) in a simple, economical, and objective way, using multi-criteria decision analysis (MCDA) with weights based on data envelopment analysis (DEA). The CI was applied to 32 municipalities in the metropolitan area of Valencia (Spain). The results show t…
Acceso a la innovación farmacéutica en cáncer. Análisis sistemático
2022
Los precios de los fármacos oncológicos están creciendo de manera muy pronunciada y junto a un aumento considerable de la incidencia de esta patología, hacen que sea necesario abordar el tema de la asequibilidad, equidad y calidad del cuidado de la salud en cáncer si no queremos que los diferentes sistemas nacionales de salud entren en bancarrota. Se han generado muchas iniciativas cuyo objetivo es evaluar el beneficio clínico de las intervenciones y así, se financien aquellas intervenciones que aporten un mayor valor tanto para los pacientes oncológicos como para la sociedad en general. Esta tesis realiza un análisis de las diferentes herramientas e iniciativas puestas en marcha por los si…
Using AHP methodology for prioritizing the actions in the transport sector in the frame of SECAPs
2020
The drafting of the Sustainable Energy and Climate Action Plan, required for the local authorities joining the Covenant of Mayors initiative, is an opportunity to plan actions reducing greenhouse gas emissions in the transport sector. Choosing the measures to implement requires the application of a methodology that compares them, considering costs and impacts in terms of energy consumption, emissions reduction, and social benefits. The paper aims to develop a method based on the typical approach of the Analytical Hierarchy Process, supporting decisions in the transport sector in the frame of the drafting of SECAP. The method allows determining the priority actions and the optimal allocation…
Safety of Dietary Guanidinoacetic Acid: A Villain of a Good Guy?
2021
Guanidinoacetic acid (GAA) is a natural amino acid derivative that is well-recognized for its central role in the biosynthesis of creatine, an essential compound involved in cellular energy metabolism. GAA (also known as glycocyamine or betacyamine) has been investigated as an energy-boosting dietary supplement in humans for more than 70 years. GAA is suggested to effectively increase low levels of tissue creatine and improve clinical features of cardiometabolic and neurological diseases, with GAA often outcompeting traditional bioenergetics agents in maintaining ATP status during stress. This perhaps happens due to a favorable delivery of GAA through specific membrane transporters (such as…
Luontoarvot ja ihmisvaikutukset soiden arvottamisessa : esimerkkinä Keski-Suomen suot
2016
Soita arvotetaan esimerkiksi maankäytön suunnittelua varten. Suunnittelua ohjaavat erilaiset ohjelmat ja tavoitteet, joita seuraamalla pyritään vähentämään turhia selvityksiä. Valtakunnalliset alueidenkäyttötavoitteet luovat päällimmäiset ohjeistukset maakuntakaavoille, joiden avulla voidaan ennalta ohjata käyttöalueita ja suojelualueita. Suunnittelua varten soita pyritään arvottamaan niiden luontotyypin ja luonnontilaisuuden perusteella. Arvottamisessa ihmisen vaikutus näkyy soilla erityisesti niiden luonnontilaisuudessa. Tutkimuksen mukaan suurimpina vaikuttajina luonnontilaisuuteen nähdään olevan mm. metsätalouden, turvetuotannon, suojelualueiden ja sijainnin. Suon muutosherkkyyteen vaik…
