Hybrid buildings are not a modern invention. In the case of certain types of buildings in historical production facilities, a degree of inseparable fusion of static buildings and dynamic mechanics can be detected. This goes far beyond the multifunctional use of a room and also includes constructional and architectural design to the same extent. They are not simply rooms or buildings in which machines for the production of an item or a product are installed, but the room, or the building, itself, is the “machine”, or at least an essential part of it. Or is the machine the building? This relationship will be explained using the example of historical oast houses. For this type of building, architectural development from an integrated yet barely perceptible component to a free-standing solitary building can be demonstrated over a period of around 80 years. It is not clear which part is the building and which is the production technology. These two main components have become an indissoluble unit, making the oast house a real hybrid.

A hibrid épületek nem a jelen kor találmányai. A történeti gyártólétesítmények egyes épülettípusainál az épület és a gépek már-már feloldhatatlan egymásba fonódása figyelhető meg. Ez a jelenség jelentősen túlmutat a többcélú helyiségeken, és egyaránt jellemző a szerkezeti és az építészeti kialakításra is. Itt már nem olyan épületekről beszélhetünk, amelyekben gépek vannak felállítva, hanem maga az épület válik a „géppé“, illetve annak szétválaszthatatlan részévé. Vagy a gép maga az épület is egyben? A fenti összefüggés bemutatása a történeti aszalók példáján keresztül történik. Közel 80 év leforgása alatt az épületben korábban alig látható berendezés szabadon álló épületté fejlődik, amelyben már-már meghatározhatatlan, hogy melyik rész tartozik még magához az épülethez és melyik rész már a gyártástechnika. A két fő komponens szétválaszthatatlan egységet alkot, vagyis az aszaló igazi hibriddé fejlődik.

Hybride Gebäude sind keine Erfindung der Neuzeit. Bei bestimmten Bautypen historischer Produktionsstätten ist eine Größenordnung der Durchdringung von statischem Gebäude und dynamischer Mechanik festzustellen, die nicht aufzulösen ist. Dies geht weit über die multifunktionale Nutzung eines Raumes hinaus, und umfasst in gleichem Maße auch die Konstruktion und architektonische Gestaltung. Es sind keine Räume, oder Gebäude in denen Maschinen zur Produktion eines Gegenstandes oder einer Ware aufgestellt werden, sondern der Raum, oder das Gebäude selbst ist die „Maschine“, oder zumindest ein wesentlicher Teil von dieser. Oder ist die Maschine das Gebäude? Am Beispiel historischer Darren soll dieser Zusammenhang erläutert werden. Für diesen Gebäudetyp kann in einem Zeitraum von etwa 80 Jahren eine architektonische Entwicklung vom visuell kaum wahrnehmbaren und integrierten Bauteil zum freistehenden Solitär nachgewiesen werden. Dabei ist nicht eindeutig festzustellen, welcher Teil das Gebäude ist, und welcher die Produktionstechnik. Aus den beiden Hauptkomponenten ist eine unauflösbare Einheit geworden, womit die Darre zum echten Hybrid wird.

Thermal bridging caused by exposed concrete balcony slab is a major source of heat loss through energy efficient building envelopes. Moreover, thermal bridging can also create moisture management and indoor comfort challenges. Numerous investigations have been carried out to reduce heat transmittance through exterior building envelopes and minimize the energy use in buildings. The most effective way to minimize heat transmittance of exposed concrete balcony slabs is to thermally separate the exterior structure from the interior structure using thermal breaks. To enhance thermal separation, this paper investigates the effects of replacing high conductive materials such as reinforced concrete or structural steel with a multilayer composition of high-performance hybrid insulating systems. Reinforcing bars, such as fiber reinforced plastics (FRPs), having lower thermal conductivity than steel are used to connect interior to exterior and transfer loads. Numerical simulation tool THERM is used to study the effects of thermal breaks on energy performance of the concrete slab balcony joints. Simulation results indicate significant thermal performance improvement while high-performance hybrid insulating systems were used for exposed concrete balcony slab constructions, compared to traditional insulating systems used in similar constructions

Abstract

Using alternative fuels (AF) in industry high consuming energy where fossil fuels are largely consumed may be a great solution to decrease CO2 emission and cost production. Or, when using these alternative fuels, the combustion may be difficult to control regarding the different components of AFs compared to fossil fuels. In this case, the use of the computational fluid dynamics CFD tools is a great solution to predict the AFs combustion behavior. This paper represents a computational study of petcoke and olive pomace (OP) co-combustion in a cement rotary kiln burner, established on the commercial CFD software ANSYS FLUENT. This study presents a useful key to choose an adequate simulation model that well predicts co-combustion problems. The performance of the K-ϵ turbulence models varieties (standard, Realizable, and Re-Normalization Group) combined with the hybrid finite rate/eddy dissipation model and the simple eddy dissipation model for predicting the co-combustion characteristics was investigated. The particle phase solutions are obtained using the Lagrangian approach. The performance of the mentioned model was evaluated based on the mesh accuracy, convergence time, temperature shape, and important chemical elements concentration. The predicted values of species concentrations and temperature are compared to the results obtained from the real case study and available literature. The standard K-ϵ model combined with the hybrid finite rate/eddy dissipation model gives the best results and the lower computational resources required for the 2-D model realized.

Due to the ISM band being unlicensed for communication applications, a lot of applications have been developed in this band and a good example is WiFi IEEE 802.11a, b, g, n of Bluetooth. This numeracy of applications motivated this paper. The paper is concerned with the design of a low distortion 20 dBm 2.4 GHz class-J power amplifier (PA) since PAs are indispensable in radio communications. The design is based on the AVAGO ATF-52189 transistor with a transition frequency of 6 GHz. The design is done as a hybrid circuit network realized using microstrip elements and surface mount device (SMD) capacitors. The schematic design and simulation are carried out using Keysight's Advanced Design System version 2016.01. The simulated PA exhibited a drain efficiency of 69% and a power output of 21 dBm.
