Suitable degree of crudeness in engineering practice

Practicing structural engineers may be familiar with the main principles of structural reliability but may not necessarily be experts in using such methods. This may lead to a lack in understanding the effect of uncertainties on the ensuing structural safety and to sub-optimization of more traditional structural engineering aspects. The aim of the current paper is to highlight the importance of co

ProLCA – treatment of uncertainty in infrastructure LCA

The construction, operation and maintenance of transportation infrastructure require energy and materials which impact the environment. Large infrastructure projects thus use resources intensively and leave a significant environmental footprint. To demonstrate and support the sustainability of such large-scale projects, life cycle assessment (LCA) has become a common tool to evaluate environmental

Reliability Analysis of Corroded Reinforced Concrete Beam with regards to Anchorage Failure

Reinforcement corrosion is a common problem in reinforced concrete infrastructure today, and it is expected to increase in the future. To simply replace the corroded structures with new ones requires large resources, both in financial and environmental terms. Therefore it is important that existing structures are used to their full potential, also after the onset of corrosion. This paper presents

Multilayer Bixin Microcapsules: The Impact of Native Carbohydrates on the Microencapsulation Efficiency and Dispersion Stability

Bixin is a hydrophobic carotenoid present in the integument of the seeds of Bixa orellana. Microencapsulation was applied to obtain water dispersible formulations and protect the colorant against degradation. Microencapsulated systems were obtained by spray-drying a mild alkaline bixin dispersion with different encapsulating materials. The encapsulation trials were performed with and without nativ

Hållbart arbetsliv för äldre medarbetare i Helsingborgs stad

Hållbart arbetsliv för alla åldrar i Helsingborgs stadI Sverige har det av samhällsekonomiska orsaker föreslagits att ålderspensionen ska senareläggas, eftersom pensionssystemet är uppbyggt så att vi ska arbeta två tredjedelar av våra liv. En av de största utmaningarna för den svenska arbetsmarknaden är att göra arbetslivet hållbart så att fler klarar av att arbeta till en högre ålder. För att fle

New Environmental Zones for Passenger Cars : Attitudes, Norms and Legal Compliance

The fundamental premise for the present report is to examine the degree to which it is possible to predict compliance with future rules regarding environmental zones for passenger cars. This project combines the main quantitative survey study (Sub-study 1) with a semi-systematic literature review that is first and foremost based in a qualitative, thematic analysis (Sub-study 2).The survey study is

Impact of lexical filtering on overall opinion polarity identification

One approach to assessing overall opinion polarity (OvOP) of reviews, a concept defined in this paper, is the use of supervised machine learning mechanisms. In this paper, the impact of lexical filtering, applied to reviews, on the accuracy of two statistical classifiers (Naive Bayes and Markov Model) with respect to OvOP identification is observed. Two kinds of lexical filters, one based on hyper
