“…In order to improve the specific plaster properties, such as water absorption, adhesiveness, and setting time, chemical additives are usually used (BALTAR; BASTOS; LUIZ, DA, 2008). Recent studies show the influence of cellulose fibers (ROSATO et al, 2017;SENFF et al, 2018), TiO2 nanoparticulate systems (ROSATO et al, 2017), expanded polystyrene, and carbonate and silica minerals (PERLOVA et al, 2016) on gypsum plaster's mechanical properties.…”

This work aimed to investigate the effects of graphene nanoparticles on the mechanical and morphological properties of gypsum plaster paste. In order to do so, samples of pure gypsum plaster paste with multilayer graphene were produced. These samples were prepared with a water/plaster factor (w/p) of approximately 0.5 with different graphene dosages. The mechanical analysis results showed that the graphene dosage of 0.02% increased the compressive and tensile strength values in the order of 120%. The increase in these properties is most likely due to the heat dissipation promoted by graphene, the greater production of crystalline nuclei and the reactivity of graphene with Ca2+ ions. Regarding the plaster setting times, a reduction in the values was observed for most samples, indicating an increase in the production of crystalline nuclei. FTIR analyzes indicate that there were no changes in terms of chemical properties.

“…As an important energy-saving method, the self-insulation technology of building exterior walls has attracted the attention of scholars in the field [13][14][15][16], for example, targeting at problems existing in the energy conservation design of building facade such as the poor thermal performance of the wall and the obvious thermal bridge effect of the steel structures, Mintorogo et al [17] proposed an exterior wall insulation system for spray-printed composite wall made of thermal insulation boards, and calculated the heat transfer coefficient of the wall. Shakouri et al [18] conducted a market survey on the thermal bridge ratio range applicable to different self-insulation systems in fixed areas, and on the price and construction cost of insulation materials; then aiming at the "heat bridge" problem of the building nodes when selfinsulation system is adopted in frame structure buildings, they built a PBECA model and calculated its energy saving rate, and then proposed targeted measures for the said problem.…”

Needless to say, green buildings have now become an inevitable trend for the sustainable development of society, and they have paved a way for the harmonious coexistence between man and nature. The design of building facade is an important part in green building construction, to achieve the optimal energy-saving effect of building facade, scholars in the field have attached great importance to this aspect and they have done works to optimize it from constituent materials, structural forms, and thermal insulation properties, etc. For the same purpose, this paper proposed a new method for the energy efficiency design of building facade and a thermodynamic evaluation method. First, the paper analyzed the factors that can affect the energy efficiency design of the wall, windows and roof of building facade; then it gave the calculation methods of parameters that are related to the energy-saving performance of building facade such as the coefficient of building shape (CBS), resistance of heat transfer, and thermal inertia (TI); after that, the paper summarized tips for the energy efficiency design of building facade, put forward a thermodynamic evaluation method for assessing the energy-saving efficiency and economic efficiency of green building facade based on the life cycle theory, and it elaborated the calculation process of energy consumption, exergy consumption and total cost of each stage in the life cycle of the building facade; at last, the paper verified the effectiveness of the new design method and the proposed evaluation method with experimental results, and the research findings of this paper can be applied to the design and evaluation of other buildings.

“…The hypothesis underlying this work is that the Archimate language can be used to support the process of requirements engineering for complex technical systems, rather than to solve only EA problems (Perlova et al, 2016) The applicability of the Archimate language to solve traditional system engineering problems is poorly investigated (Grobshtein et al, 2007). The goal of the work is to assess the applicability of Archimate in the development of systems of various classes.…”

Requirements engineering represents the most crucial stage in the complex systems development process. Contemporary methods of requirements engineering assume a wide application of models (described, for example, with such languages as SysML or OPM), which allows to ensure the consistency and completeness of the system descriptions. The article assesses the applicability of the Archimate language to support the process of requirements engineering when creating complex technical systems. Requirements engineering method for complex technical systems, suitable for models described by the Archimate language is proposed. Detailed example demonstrating the proposed method when developing system requirements is given. The limitations of the Archimate language applicability for the engineering of systems of various classes are described.
