Компактный аппаратно-программный комплекс для диагностики электронных регуляторов САУ ГТД в эксплуатации

The relevance of creating a compact hardware and software complex is analyzed to ensure a full check of the operability of electronic regulators of gas turbine engines, in particular, the AI-35 engine, developed by SE "Ivchenko-Progress". The article describes the composition and functionality of the device developed by Element JSC, which was named “Complex of software and hardware for imitation of actuators and engine sensors”. The complex under consideration is intended both for autonomous use and for work as part of an automated workstation (AWS), which in turn is a part of the AI-35 engine semi-natural simulation stand. A feature of the complex is that it contains built-in mathematical models of the engine, electric drive pump-fuel regulator, as well as sensors installed on the engine. Based on the results of processing digital signals from an automated workstation or a touchscreen display, the complex generates output analog and frequency signals – rotor speed, pressure at the compressor outlet, the temperature at the compressor inlet, temperature of gases at the outlet of the turbine. The complex also generates control signals for the imitation of igniting pyro plugs and a fuel pyrovalve, in particular, it provides an imitation of their "combustion" by breaking the circuit. The built-in touchscreen display makes it easy for the operator conducting the governor and engine tests to use the complex as intended. With the help of the display, without using a PC, the operator can manually control the process of simulating the issuance of a command to start the engine by changing the values of the rotor speed, form various modes of engine operation, setting the appropriate parameters, simulate engine surge, etc. The functionality of the developed complex provides debugging of GTE control algorithms and subsequent tests of the regulator.

Ophthalmic Evaluation of Diagnosed Cases of Eye Cystinosis: A Tertiary Care Center’s Experience

Background: We aimed to identify diagnosed cases of ocular cystinosis and describe clinical, epidemiological and therapeutic characteristics. Methods: This is a descriptive and retrospective case series. All patients underwent a full check-up examination every 4–6 months by ophthalmologists, nephrologists and other required specialists. Results: Of the seven cases, six (85.7%) were females and one (14.2%) was male. The infantile nephropathic form of cystinosis was observed in five patients and the juvenile nephropathic form in two patients. No patients with the ocular form of cystinosis were identified. Corneal cystine crystals (CCC) were found in all analyzed patients. Severe ocular and general complications of the disease that had been standing for years, connected to the infantile nephropathic form, delayed diagnosis or inappropriate treatment, were observed only in two patients. All patients received topical therapy. No adverse events related to the therapy were observed. Conclusions: Cystinosis is a rare, progressive disease. Early diagnosis and treatment prevent serious complications from numerous systemic organs. Patients require constant systematic monitoring by various specialists.

An overview of genera and subgenera of the Asura / Miltochrista generic complex (Lepidoptera, Erebidae, Arctiinae). Part 1. Barsine Walker, 1854 sensu lato, Asura Walker, 1854 and related genera, with descriptions of twenty new genera, ten new subgenera and a check list of taxa of the Asura / Miltochrista generic complex

Lithosiini genera of the Asura / Miltochrista generic complex related to Barsine Walker, 1854 sensu lato and Asura Walker, 1854 are overviewed. Barsine is considered to be a group having such an autapomorphic feature as a basal saccular process of valva only. Many species without this process are separated to the diverse and species-rich genus Ammatho stat. nov., which is subdivided here into eight subgenera including Idopterum Hampson, 1894 downgraded here to a subgenus level, and six new subgenera: Ammathella Volynkin, subgen. nov., Composine Volynkin, subgen. nov., Striatella Volynkin & Huang, subgen. nov., Conicornuta Volynkin, subgen. nov., Delineatia Volynkin & Huang, subgen. nov. and Rugosine Volynkin, subgen. nov. A number of groups of species considered previously by various authors as members of Barsine are erected here to 20 new genera and four subgenera: Ovipennis (Barsipennis) Volynkin, subgen. nov., Ovipennis (Coccinigripennis) Volynkin & Huang, subgen. nov., Barsura (Tenebrasura) Volynkin, subgen. nov., Argentosine Volynkin, gen. nov., Esmasura Volynkin & Huang, gen. nov., Matsumursine Volynkin & Huang, gen. nov., Floridasura Volynkin, gen. nov., Fossia Volynkin, Ivanova & Huang, gen. nov., Wittasura Volynkin, gen. nov., Disparsine Volynkin, gen. nov., Moorasura Volynkin & Huang, gen. nov., Sarbine Volynkin, gen. nov., Sarbine (Processine) Volynkin, subgen. nov., Hampsonascia Volynkin, gen. nov., Cernysura Volynkin, gen. nov., Barsilene Volynkin & Huang, gen. nov., Nanarsine Volynkin, gen. nov., Amphisine Volynkin, gen. nov., Karolia Volynkin, gen. nov., Niveutane Volynkin, gen. nov., Rubrindiania Volynkin & Huang, gen. nov., Barsaurea Volynkin & Huang, gen. nov., Integrivalvia Volynkin & Huang, gen. nov. and Aberrasine Volynkin & Huang, gen. nov. The genus Nebulene Volynkin & Černý is downgraded to a subspecies of Ovipennis. The genus Eutane Walker, 1854 is downgraded to a subspecies of Asura. The genera Miltasura Roepke, 1946 and Gymnasura Hampson, 1900 are synonymised here with Cyme Felder, 1861 and Asura respectively. The genera Asuropsis Matsumura, 1927, Neasuroides Matsumura, 1927 and Asuridoides Daniel, 1951 are synonymised with Miltochrista Hübner, [1819]. The genus Allochrista Roepke, 1946 is synonymised with the subgenus Thyrgorina Walker, [1865] of the genus Lemyra Walker, 1856 (tribe Arctiini) with establishing a new combination Lemyra (Thyrgorina) toxopei (Roepke, 1946), comb. nov. Other six new synonyms are established: Barsine pardalis (Mell, 1922) = Barsine miranda Kishida & Wang, 2017, syn. nov., Barsine striata striata (Bremer & Grey, 1852) = Miltochrista quelparta Okamota, 1924, syn. nov., Floridasura tricolor (Wileman, 1910) = Barsine coccinea Moore, 1886, syn. nov., Disasuridia metaphaea (Hampson, 1900) = Disasuridia flava Fang, 1991, syn. nov., Aberrasine aberrans aberrans (Butler, 1877) = Miltochrista decussata (Moore, 1877), syn. nov. and Cabarda nigripuncta (Wileman & South, 1919) = Asura lunilinea Schaus, 1922, syn. nov. In addition, it is stated that Miltochrista quadrifasciata Rothschild, 1913 described from New Guinea and currently belonging to the genus Cyme (a junior synonym of Cyme sexualis (Felder, 1864)) is an invalid name, being a secondary junior homonym (homonym nov.) of Cyme quadrifasciata (Rothschild, 1913), comb. nov. described from Sulawesi. A full check-list of members of the Asura / Miltochrista generic complex with 370 new combinations is present.

Application of constant-weight code "1-out-if-5" for the organization of combinational circuits check

Objective: To study specificities of “1-out of-5”equilibrium code application in the process of concurrent error detection of combinational logic circuits organization. Methods: Information and coding theories, as well as technical diagnostics of discrete systems were applied. Results: It was suggested to apply a “1-out of-5”equilibrium code in organizing of combinational circuits control by means of Boolean complement method, the tester of which has a simple structure and needs five testing patterns for its full check. The calculation method of Boolean complement functions was given; the former makes it possible to provide testability of a Boolean complement block and a tester within a checking circuit. The advantages of a “1-out of-5”equilibrium code application were presented, compared to the usage of other equilibrium codes with a shorter length of a code word for organization of combinational circuits’ check. Practical importance: The application of a “1-out of-5”equilibrium code for organization of combinational circuits’ check is promising for self-checking discrete automatic and calculating machines.
