AbstractBuilding adaptation and re-use can contribute to a circular and sustainable built environment, as existing buildings are adapted and the need for new construction materials is reduced. The “adaptability” of buildings has been widely studied; however, few of these studies are quantitative. This paper uses Artificial Neural Networks (ANN) and Logistic Regression (LR) models to explore relationships between the physical features of buildings and their demolition or adaptation outcomes. Source data were taken from 59 buildings that were either demolished or adapted in the Netherlands. After the models were created and validated, a series of sensitivity studies were conducted to evaluate relationships between physical parameters and building outcomes. The physical parameter with the strongest relationship to adaptation outcomes was demountability (ease of removal) of building service elements. The quantitative results were then compared to results from an adjacent qualitative study. The relationships observed from the quantitative sensitivity studies align well with the qualitative observations.

Our recent excavations at the site of Yautepec in the Mexican state of Morelos have uncovered a large set of residential structures from an Aztec city. We excavated seven houses with associated middens, as well as several middens without architecture. In this paper, we briefly review the excavations, describe each house, and summarize the nature of construction materials and methods employed. We compare the Yautepec houses with other known Aztec houses and make some preliminary inferences on the relationship between house size and wealth at the site.

AbstractWe use a new construction of an o-minimal structure, due to Lipshitz and Robinson, to answer a question of van den Dries regarding the relationship between arbitrary o-minimal expansions of real closed fields and structures over the real numbers. We write a first order sentence which is true in the Lipshitz-Robinson structure but fails in any possible interpretation over the field of real numbers.

Concrete is the most versatile, durable and reliable material and is the most used building material. It requires large amounts of Portland cement which has environmental problems associated with its production. Hence, an alternative concrete – geopolymer concrete is needed. The general aim of this book is to make significant contributions in understanding and deciphering the mechanisms of the realization of the alkali-activated fly ash-based geopolymer concrete and, at the same time, to present the main characteristics of the materials, components, as well as the influence that they have on the performance of the mechanical properties of the concrete. The book deals with in-depth research of the potential recovery of fly ash and using it as a raw material for the development of new construction materials, offering sustainable solutions to the construction industry.

В статье анализируются особенности восприятия лесного пространства башкирами. На основе языковых, фольклорных материалов сделана попытка раскрыть различные аспекты взаимоотношений лес - человек, образ леса в картине мира башкир. Как и в большинстве традиционных культур, в целом мифологический образ леса носит отрицательный характер. В фольклоре он часто описывается как тёмный, мрачный, неизвестный, таящий опасности, противопоставляясь обжитому и освоенному пространству селений. Лесной пандемониум также представлен в основном отрицательными персонажами. В целом образ леса в традиционной картине мира башкир предстаёт довольно неоднозначным. С одной стороны - это категория, связанная с потусторонним миром, неизведанная, «чужая» территория. С другой - лес издавна являлся источником различных благ - в виде строительного материала, пушнины, различных продуктов питания, укрывал от врагов. The article analyzes the features of Bashkirs' perception of the forest space. On the basis of the materials of the epos, folklore, folk ideas, an attempt was made to reveal the various aspects of the relationship between forest and man, the image of the forest in Bashkirs' world view. As in most traditional cultures, the mythological image of the forest as a whole is negative. In folklore, it is often described as dark, gloomy, unknown, fraught with danger, being contrasted with the inhabited and developed space of the villages. The forest pandemonium is also represented mainly by negative characters. On the other hand, in the domestic perception forest is valued for the benefits derived from it: shelter, food, protection from enemies. In addition, Bashkirs, distinguished by a developed aesthetic perception and contemplative thinking, appreciated its beauty, which is also reflected in folklore. In general, the image of forest in the Bashkirs' traditional view of the world appears rather ambiguous. On the one hand, it is the category associated with the other world, unknown, «foreign» territory. On the other hand, the forest has long been a source of various benefits - in the form of construction materials, furs, various food products, and it sheltered them from enemies.

This paper exhibits a method to improve the quality of musical instruments with the application of two Multi-Criteria Decision Making models, Technique of Order Preference by Similarity to Ideal Solution (TOPSIS) and Analytic Hierarchy Process (AHP) in a Quality Function Deployment (QFD) Environment. A fuzzy analysis approach was also included to accommodate qualitative data in music. The QFD was constructed with literature based on optimizing the manufacture of musical instruments. At this phase of the research, the paper focused on the physical parameters and perceived qualities of musical instruments. The proposed modified QFD was developed to identify the product features chosen by the market and aid the manufacture of musical instruments. A standard QFD recognized and scored factors to develop and manufacture musical instruments. It accommodated some core engineering variables for the musical instruments but overlooked some feature stakeholder needs. For example, the musician may not have 100% gratification while playing the instrument as the manufacturer fails to capture acoustic features to psychologically satisfy the musician’s audience. Using fuzzy logic, QFD and MCDM increased the model performance by expanding the data set. It offered the manufacturer of musical instruments a mode to capture and analyse behavioural linguistic data covering more customer requirements. Hence, the approach increased the range to correlate the physical features and psychological behaviours of musical instruments. It allowed non-technical persons to provide an improved form of reliable information. This modified QFD can also be applied to develop other products involving linguistic data.

The Relationship

Canal system conveyance efficiency (CSCE ) is a basic parameter of engineering construction and water management of the irrigation districts, either the response of operation status of an irrigation canal system. It plays great significance in searching quantity relationship between ICSCE and other basic parameters reflecting the condition of irrigation engineering. This paper, gravity irrigation districts in Zhejiang province as an example, sets up the relationship between basic parameters such as irrigation canal lining rate, canal flow and the CSCE, based on determining the CSCE in 61 typical gravity irrigation districts. And it also reflects the influence of basic parameters on CSCE, having a certain accuracy. This result plays a positive role on the further research and actual work on CSCE.
