The use of pumice lightweight concrete for masonry applications
2011
In the last two decades, the use of pumice as lightweight aggregate for concrete in structural applications has been the object of different studies. The aim was to find out if pumice can be an alternative to ordinary lightweight aggregate. The present paper is framed in this context. Here, a study is presented showing the use of pumice for making lightweight concrete units for masonry members. Through the paper, the formulation of a mix design for lightweight concrete is proposed. Then the obtained mechanical characteristics of the masonry units are discussed and compared to the code requirements. Reinforced bearing masonry walls, made with the concrete masonry units in question, were made…
Fault diagnosis of induction motors broken rotor bars by pattern recognition based on noise cancelation
2014
Current signal monitoring (CSM) can be used as an effective tool for diagnosing broken rotor bars fault in induction motors. In this paper, fault diagnosis and classification based on artificial neural networks (ANNs) is done in two stages. In the first stage, a filter is designed to remove irrelevant fault components (such as noise) of current signals. The coefficients of the filter are obtained by least square (LS) algorithm. Then by extracting suitable time domain features from filter's output, a neural network is trained for fault classification. The output vector of this network is represented in one of four categories that includes healthy mode, a 5 mm crack on a bar, one broken bar, …
“Optime educatus” : Book historical perspectives on Prince Sigismund’s education in sixteenth-century Sweden
2022
The article analyses some aspects of writing in Prince Sigismund Vasa’s (1566-1632) education in the latter half of sixteenth-century Sweden. The focus is on the rare, hand-written material of his youth, which reflects the educational ideals, practices and strategies in the inter-confessional Jagiellon–Vasa family and at their court(s) in the context of a complex political situation. One example is young Sigismund’s salutation to the Pope included in her mother’s, Catherine Jagiellon’s (1526-1583), letter. In addition, two letters held at the Riksarkivet (Swedish National Archives), Stockholm, categorized as “royal autographs” are explored and transcribed for the first time. peerReviewed
A cultural analysis of the visual signs in the Zapatistas websites
2012
A political movement initiated in Mexico known as Zapatism is analysed through the visual objects displayed in their websites on the Internet. The objective is to make a cultural analysis and interpretation of the visual representation of Zapatistas websites, to expose their visual identity through the most salient visual signs and their corresponding cultural meanings. The analytical method introduced in this study is divided in three major aims: consolidating a pool of images retrieved from Zapatistas websites, finding patterns of visual elements within these images, and providing an interpretation for the visual signs emerging from such patterns. In the analysis, three images emerged as …
The squeaky clean image of soap in advertising
2014
Go and wash your hands; give them a good scrub and a good rinse… " We can all remember that little chorus of parental discourse before dinner or any other time one has to look immaculate. Our first symbolic relationship with soap is perhaps something of this nature: hands first, followed by the sink and the simple act of washing. But this relationship with soap and its derivatives, which has now become every day, both functional and intimate, involves all manner of shapes, colours, materials and affective nuances affecting our choice of the right soap for us. Our criteria: its composition, its fragrance or scent and mouth-watering notes, its presentation, its shelf-life? Its designation, to…
Intellectual Capital Reporting in the Italian Nonprofit Sector. An Image-Building or an Accountability Tool?
2014
Abstract The purpose of this article is to analyze intellectual capital (IC) measurement, management, and reporting practices at organizational level, with the aim to address a relevant research question: are IC reports used as accountability or as image-building tools? The article presents a single in-depth case study of an Italian nonprofit organization (NPO) which has been measuring and reporting its IC for several years. The research project was conducted using an interpretative approach, by analyzing organizational IC reports in the light of a framework, derived from corporate social responsibility (CSR) and IC literature, able to provide researchers with useful insights to interpret t…

An Information Systems Design Theory for Integrated Requirements and Release Management Systems
2009
High-tech companies need to collect and analyze requirements and allocate them to appropriate product releases in market-driven product development. Development activities are typically scattered across multiple sites and involve multiple partners in different countries, complicating requirements and release management. Flexible, scalable, and secure groupware-based support for the activities provides substantial payoffs. Yet, the extant literature provides little theoretical guidance for designing and using requirements and release management systems in multi-site, multi-partner environments. This article develops the meta-requirements and a meta-design of an information systems design the…
