The problem of determining the optimal the values of the parameters of the PI controller by the quadratic integral criterion taking into account the coefficient of attenuation of the transition process. The problem is presented as a nonlinear mathematical problem programming. Finding the global minimum of the objective function carried out by random search, and to determine the parameters of the PI controller used the expanded amplitude-phase frequency response of the system. An attempt is made to provide designers with an effective tool for solving the above problem. The given graphs and tables facilitate the selection of parameters. To compile a computer program, the visual programming system VBA (Visual Basic for Application) is used. Concrete examples are given.

Construction companies face barriers and challenges in adopting BIM, as there are no guidelines or best practices they could study and use in their activities. One of the most difficult and time-consu­ming tasks in designing construction projects is calculating the volume of earthworks, which sometimes has to be done in difficult climatic conditions. The article presents a study of using BIM technology and the development of a script in the visual programming environment «Dynamo», which will simplify this labour intensive process without losing its quality and saving time for other design tasks. The deve­loped script can be used when calculating earthworks and studying their fill diagram in order to cut costs of performing initial construction works by designing marks on the Earth’s surface. It can be used in road building when plotting the most economically feasible route in terms of construction costs. The use of the developed script will significantly reduce the time of performing a big amount of same type repetitive operations when developing representative units or creating complex parametric geometry.

This book describes a powerful language for multidimensional declarative programming called Lucid. Lucid has evolved considerably in the past ten years. The main catalyst for this metamorphosis was the discovery that Lucid is based on intensional logic, one commonly used in studying natural languages. Intensionality, and more specifically indexicality, has enabled Lucid to implicitly express multidimensional objects that change, a fundamental capability with several consequences which are explored in this book. The author covers a broad range of topics, from foundations to applications, and from implementations to implications. The role of intensional logic in Lucid as well as its consequences for programming in general is discussed. The syntax and mathematical semantics of the language are given and its ability to be used as a formal system for transformation and verification is presented. The use of Lucid in both multidimensional applications programming and software systems construction (such as a parallel programming system and a visual programming system) is described. A novel model of multidimensional computation--education--is described along with its serendipitous practical benefits for harnessing parallelism and tolerating faults. As the only volume that reflects the advances over the past decade, this work will be of great interest to researchers and advanced students involved with declarative language systems and programming.
