The main ridge of the Alps lays just crosses Austria. Therefore it is not surprising that most highways in Austria do have to pass through a lot of road tunnels. Among these tunnels, some of the world longest tunnels for vehicle traffic are found. For safety reasons today all long road tunnels are planed with two tubes. Two tubes allow one way traffic in each tube. In the case of one way traffi...

sheet metal components design and manufacture need a great deal of experience and know-how. strip layout design is usually done with trial and error until best design for strip layout is finally achieved. knowledge for the system is formulated from plasticity theories, experimental results, and the empirical knowledge of field experts. in this paper, an algorithm which can automatically design ...

Both the quality of the results of TEX s formula layout algorithm and the complexity of its description in the TEXbook are hard to beat The algorithm is verbally described as an imperative program with very complex control ow and complicated manipulations of the data structures representing formulae In a forthcoming textbook we describe TEX s formula layout algorithm as a functional program tra...

With the enhancement of people’s awareness heritage protection, research communities focusing on natural ventilation layouts ancient buildings have paid more attention to planning and protection these buildings. Based relationship between environment layout building, we can reduce adverse effects energy consumption outdoor wind, improve quality around achieve harmony humans nature. In this stud...

The building sector represents approximately 40% of the global energy consumption, which 18 to 73% is represented by heating and ventilation. One focus research for reducing consumption study interaction between system, occupant’s behaviour, building’s thermal mass. For this purpose, a new experimental facility was developed. It consists real accommodation in performance envelope, room’s layout...

According to the discussion of design method and operational effect for Wuhan Huoshenshan Hospital, this paper summarized control points indoor outdoor environment COVID-19 emergency hospital. Based on analyzed discussed site design, building layout, three-zones two-passages, scheme ventilation air conditioning system negative pressure ward isolation ward, distribution, as well some other key d...

The survey highlights that students of university regularly visit libraries to borrow books. Most have sufficient infrastructure like layout, lighting, ventilation, and clean premises. They an easily accessible location as well. In libraries, there is mostly a collection textbooks but inadequate journals/magazines for students. Moreover, open access documents electronic information resources av...
