Organization of rights and responsibilities in complex 3D real property developments - the relevance of bridging research fields

The condominium concept is one form of 3D property that is used in many countries around the world to organize and register 3D real property situations. Condominium property was mainly introduced in various jurisdictions to facilitate homeownership by converting residen-tial apartment units in high-rise buildings into real property. Thus, the...

Effects of the pre-absorption of superabsorbent polymers and the water-cement ratio of paste on the adsorption-desorption of superabsorbent polymers: an NMR study

As an internal curing material, superabsorbent polymers (SAPs) can effectively reduce the risk of volume shrinkage of cement-based materials. By preparing the cement paste mixed with SAPs, the amount of pre-absorbed water and the water-cement ratio of paste on the water absorption-release behavior in the fresh cement paste were studied by using...

Concrete mixing monitoring by image analysis applied to recycled aggregate concrete

The improvement of inline mixer measurements is imposed in a growing concrete industry employing increasingly complex manufacturing processes and materials. Improper mixing, water content estimation and fresh properties control are one of the most important concerns of concrete manufacturers. These problems have increased in recent decades due...

Mixing recycled aggregates concrete – old methods for new concrete

There have been a great number of laboratory studies on mixing approach for recycled aggregate concrete (RAC) even if in practice, the simplest procedures are generally employed. Some of these methods give good results comparing with the traditional mixing method. The present paper resume some main mixing methods proposed in the literature,...

Separation in air jigs of mixed construction and demolition waste

Air jigging technology has been highlighted as a promising method for the sorting of recycled aggregates from CDW. In this study, the broadening of its application for CDW recycling by the combined removal of unwanted stony materials and low-density organic compounds is discussed. Tests were performed with binary mixtures containing concrete and...

Turbulent entrainment in a shearless mixing layer at the edge of a cloud

Three-dimensional direct numerical simulations which combine the Eulerian description of temperature, vapor content and velocity with a Lagrangian ensemble of cloud water droplets are used to study the turbulent entrainment and subsequent mixing of clear air with a cloudy air filament. The study is conducted in a shearless mixing layer setup...

A critical overview of Architectural Competitons in Turkey: Two contradicted competition stories in Istanbul: IMC blocks / Zorlu Center projects

This paper’s aim is to make a comparative analysis of the two contradicted multi-leg mixused projects and their architectural and urban design process / the competition process; the communist, nationalist, designer-related, revolutionary, innovative, transparent, extroverted, humble, urban related IMC Blocks include the Linen and Drapers Offices...

Exploring Reciprocal Relationships of Land-Uses in a Historical Mixed-Use Quarter of Istanbul: Measuring mixed-use patterns of Cihangir

In this paper we explore the land-use patterns of a historical mixed-use quarter of Istanbul by focusing on the reciprocal relationships of housing and commercial uses. We are concerned with the distribution of land-use patterns based on spatial adjacency and land-use patterns within the buildings. We measure reciprocal relationships of housing...

Buildings with an Attitude: Personality traits for the design of interactive architecture

In order to achieve interactive architecture it is necessary to consider more than the technological components of sensors, controllers, and actuators. The interaction can be focused to different interaction activities: instructing, conversing, manipulating, and exploring (we propose to call this the interaction view). Additionally, the purpose...

Design of polymeric capsules for autonomous healing of cracks in cementitious materials

Now, most of the capsules used to contain polymeric healing agents in self-healing concrete, are made of glass. However, glass capsules cannot be mixed in concrete and are therefore placed manually into the moulds during concrete casting in laboratory tests. This represents a major drawback for an eventual industrialisation. In this study,...

Conflicting flexibility

New buildings are designed for first users. For a sustainable approach there are many advantages in designing in flexibility and adjustability in order to enable and facilitate the other sequential users. For the first investor this flexibility is translated into improved exit values due to increased potential. The second investor is acquiring a...

CFD simulation of multiphase melt flows in steelmaking converters

The three-dimensional, transient, non-isothermal flow of melt, slag and oxygen/argon is simulated for a 335 t combined blowing converter with six-hole top lance and 14 bottom tuyeres. The calculation is based on the Reynolds averaged Navier-Stokes (RANS) equations and the Standard k-epsilon model. The time-dependent formation of the melt...

ILES of shock waves and turbulent mixing using high-resolution Riemann solvers and TVD methods

This paper derives the implicit model for high-resolution MUSCL reconstruction-based upwind Godunov schemes for turbulent flows. A Mach number expansion of the numerical scheme allows analysis of the theoretical behaviour of the implicit subgrid model as the Mach number becomes small. This shows that different limiting methods within the same...

Design and flow analysis of radial and mixed flow turbine volutes

Radial and mixed flow turbines which are an important component of a turbocharger consist essentially of a volute, a rotor and a diffuser. Vaneless volute turbines, which have reasonable performance and low cost, are the most used in turbochargers for automotive engines. Care has to be done in the design of the volute, whose function is to...

Numerical coupling of petroleum wellbore and reservoir models with heat transfer

The talk is devoted to the modelling and the finite element approximation of the flow of a monophasic compressible fluid in a petroleum reservoir and wellbore, from both a dynamic and a thermal point of view. To do that, we couple a reservoir model, including viscous dissipation and compressibility effect, with a pseudo 1D wellbore model, taking...

Mixing enhancement by shock impingement in a generic scramjet combustion chamber

The present paper focuses on the mixing improvement in a generic supersonic combustion chamber for a fixed combustion chamber height with wall injection. On the one hand, internal shocks are employed to increase mixing and penetration, on the other hand injector design and spacing are investigated to achieve good penetration and mixing. With...
