The problem of energy consumption of thermal flow sensors remains relevant. This is especially characteristic when powering destination sensors from autonomous, i.e., small-sized, low-power, low-voltage electrochemical cells. A decrease in energy consumption (power and heating temperature) leads to the parasitic effect of signal line resistances and, as a result, to the deterioration of functional characteristics, in particular, to a decrease in the accuracy of flow rate measurement.","PeriodicalId":142101,"journal":{"name":"Optoelectronic information-power technologies","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134243701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interval model reflects the distribution of the amplitude of the information signal - the reaction to stimulation of the tissues of the surgery area with an alternating current of limited amplitude. The technical and software means of detection and visualization of the recurrent laryngeal nerve were analyzed. A method of identifying the specified mathematical model is proposed, which is based on the procedures for solving a nonlinear optimization problem. The proposed method simplifies the procedure for identifying the parameters of the interval model, in particular, due to the analytical representation of the objective function of the optimization problem, in contrast to the known method, where this function is discrete. The model was verified on experimental data obtained during the thyroid surgery. The developed interval nonlinear model makes it possible to detect and visualize the placement of the laryngeal nerve in the area of surgical intervention during the operation and, accordingly, ensures a reduction in the risk damage of its.","PeriodicalId":142101,"journal":{"name":"Optoelectronic information-power technologies","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125361400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Functional disorders of nasal breathing in the future lead to further complications of the upper and lower respiratory system, reduce the quality of life and lead to other pathological conditions. The diagnosis of such disorders is complicated by the low prevalence of nasal breathing testing tools (rhinomanometers) in medical practice and the peculiarities of functional research methods, which are particularly related to the low repeatability of results and the lack of a clear correlation between diagnostic data and the patient's objective feelings. The obtained data on the total coefficients of aerodynamic nasal resistance, which are determined using the methods of front and rear active rhinomanometry, correspond quite clearly to each other within 12%. The values of the total coefficients of nasal resistance, obtained by the method of posterior rhinomanometry, in all typical cases differ to a lesser extent. The perspective of the work is to gather statistical data to determine the features of nasal breathing testing to obtain accurate personalized values of nasal resistance coefficients in different breathing modes, taking into account individual variability.","PeriodicalId":142101,"journal":{"name":"Optoelectronic information-power technologies","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126650184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
