However, in order to determine their use in different concrete applications, it is necessary to know the impact on the mechanical properties and the benefits that can be obtained by incorporating t...

NEURAL NETWORK-BASED MODELS FOR STRUMA RIVER FLOW FORECASTING

(STEF92 Technology, 2023-10-01, Snezhanka Balabanova, Vesela Stoyanova, Valeriya Yordanova)

Show more

Accurate river flow forecasting is an extremely important issue for proper management and optimal use of water resources as well as for warnings of extreme hydrometeorological events. Rainfall-runoff simulation is essential for short and longterm forecasting of the river discharge. Determining the relationship between rainfall and runoff is one of the most important tasks faced by hydrologists. This relationship is a nonlinear and extremely complex process influenced by many factors such as watershed topology, veg...

NONVIOLENCE OR REVOLUTION. TOWARDS A HYBRID AND ANTI-SPECIESIST ARCHITECTURE

(STEF92 Technology, 2023-12-15, Tommaso Antiga)

In 1923 Le Corbusier-s Vers une architecture was published for the first time, maybe the most influential essay for the discipline ever. Imprinted on the title page of that first edition was the photo of the deck of the steamer Aquitaine, at the time the most up-to- date result of the industry: from there, the -machine- became the model for a radical renewal of architecture. Nowadays, in 2023, who would ever dream of presenting the latest cruise ship or a super-jet as a paradigm for a renewed architecture? In fact...
