  • Application the operation of vectoring conditions for the synthesis of digital state machines

    The article discusses a method for optimizing the synthesis of digital state machines for solving tasks of search patterns with masks on FPGA using automatic models. Standard methods for the synthesis of the FPGA don't optimize digital state machines, but only optimize the placement of logic elements on the chip. The method of vectoring states involve the decomposition the structure of the machine and the combining the variety of states to the vertex-array of states. The states in the vertex-array is controlled by special state machine. This simplifies the addressing to the heights of states of the graph , and optimizes logical structure of machine. The number of states of the digital machine remains unchanged. Vectorization of states is simplifying the synthesis and control of state machine and reduces the number of logical elements.

    Keywords: digital state machine, graph of digital state machine, synthesis of digital state machine, FPGA, reconfigurable computing system, pattern search, vectoring states of digital state machine.

  • Оптимизация режима формования полимерных композитных конструкций на основе метода Парето

    Одним из важнейших факторов, исключающих возникновение дефектов типа пор, расслоений, участков с неполной полимеризацией связующего в формуемой высоконагруженной полимерной композитной конструкции, является управляемость процесса во всем объеме композита. Для обеспечения однородности процесса полимеризации связующего предложен метод многокритериальной оптимизации процесса на основе математической модели, связывающей процессы распространения тепла и кинетики полимеризации. Система связанных уравнений процесса, учитывающая экзотермическое тепло, выделяемое при полимеризации термореактивного связующего, изменение теплоемкости и теплопроводности композита при фазовых переходах от жидкого к гелеобразному и, далее, к твердому состоянию, точную геометрию технологической системы, включая прессформу, а также интенсивность тепловыделения независимо управляемых нагревателей, реализована в виде конечноэлементной модели. Предложенный метод синтеза закона оптимального управления нагревателями, использующий метод множеств Парето, проиллюстрирован на примере полимеризации разностенной композитной конструкции, формуемой из стеклопластика.

  • Breath analysis for diagnosis of halitosis

    This article considers the causes of halitosis and methods of the diagnosis. Halitosis, syndrome of bad breath caused by pathological condition of the oral cavity or internal organs and systems, has a significant impact on the patient's social life. Analysis of the composition of exhaled air may become a promising way to diagnose halitosis, as the direct relationship between the compositions of molecules of oxygen, carbon dioxide, nitrogen oxides, ammonia etc. and the causes of halitosis were found. The article's authors review and analysis the methods of measurement of qualitative and quantitative composition of exhaled air. The most common methods include the use of electrochemical, optical sensors, infrared spectrometers and mass spectrometers. The latter method is positioned as the most optimal method of analysis of exhaled air due to its high accuracy, selectivity and sensitivity. The authors' portable mass spectrometer being developed is represented. At this stage it can detect traces of oxygen and carbon dioxide, which inject into the device through the capillary system or membrane one, in gas samples in real-time mode.
