Reducing Time to Reset a Stateful System Under Test (SUT)

The qualification of continuously running, stateful systems requires a full reset to initial state due to the state-altering nature of a finite workload. A full reset entails teardown and restart of the system to a known initial state, which can cause the workload to experience long downtimes for the duration of the reset. This disclosure describes techniques that reduce reset durations that occur in the context of testing stateful systems. In a one-time operation, an initial state is maintained in persistent storage, e.g., in cloud-based virtual disks. The system under test (SUT) is reset using the stored initial image. The time saved in the obviated teardown-and-restart procedure directly translates to reduced startup and qualification times and obviates other time-consuming procedures such as reinstalling dependent libraries and software. The techniques generally reduce interruptions in testing and are especially useful for narrow rollout windows

ХИМИЧЕСКИЕ СЕНСОРЫ НА ОСНОВЕ НАНОСТРУКТУРИРОВАННЫХ МАТЕРИАЛОВ. ЧАСТЬ 1. ГАЗОВЫЕ СЕНСОРЫ. (Обзор)

Analysis of modern methods of preparation of gas sensors than utilize nanostructural materials in the basic construction has been made. Nanostructural materials utilization in the sensor increases specific surface area of its sensitive layer. Two groups of the methods that promote to solve this task were selected. The first one is related to the utilization of nanoporous anodic alumina substrate and/or membrane as sensor template. The second one includes the preparation of the sensitive layers based on the 1D–3D nanostructures. Enhancement of the sensor output characteristics is determined by the collection of advanced physicalchemical properties of nanomaterials and nanostructures utilized in the sensor construction.Проведен анализ современных методов изготовления газовых сенсоров, в элементах конструкции которых используются наноструктурированные материалы. Выделены две группы методов, способствующих увеличению удельной поверхности чувствительного слоя сенсора: первая – использование в качестве основы для кристалла сенсора подложки или мембраны из нанопористого анодного оксида алюминия, вторая – формирование чувствительных слоев  газового сенсора с  большой  удельной  поверхностью  на основе 1D–3D наноструктур. Повышение выходных характеристик сенсора определяется совокупностью улучшенных физико-химических свойств наноматериалов и наноструктур, используемых в его конструкции

Development of an exemplary 10-day school menu in accordance with the requirements of Sanpin 2.3/2.4.3590-20

The article presents materials reflecting the developed exemplary 10-day menu of school breakfasts, lunches and afternoon snacks for the age groups of 7-11 years and 12 years and older for the organization and implementation of school meals in accordance with the requirements of SanPiN 2.3/2.4.3590-20. The scope of the developed materials includes schools and public catering enterprises that organize meals for schoolchildren based on the principles of healthy eating in accordance with the requirements of the Sanitary and Epidemiological Rules and Norms SanPiN 2.3/2.4.3590-20 «Sanitary and Epidemiological Requirements for the Organization of Public Catering of the Population « (approved by the Resolution of the Chief State Sanitary Doctor of the Russian Federation dated October 27, 2020 No. 32). When calculating the school menu, the requirements for the cost of a grocery set have been taken into account (no more than 58.39 rubles per day per student for the age category of 7–11 years and 12 years and older for school breakfast; no more than 58.39 rubles per day for one student of the age category of 7–11 years old and 65 rubles per day for one student of the age category of 12 years and older for a school lunch; no more than 18.75 rubles per day for one student of the age category of 7–11 years old and 22.75 rubles per day for one student of the age category of 12 years and older for a school afternoon snack). The developed exemplary 10-day menu of school breakfasts, lunches and afternoon snacks for the age categories of 7–11 years and 12 years and older have passed an examination in the Office of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare in the Republic of Adygea and received a positive conclusion (01-00-03/58-4986-2021 dated August 27, 2021) and can be recommended for the use in educational institutions. The optimal period for the development (at least three months) and approbation (at least six months) of an exemplary school menu should be considered from six months to a year. In addition, the menu for school meals should be multivariate, including options for people with disabilities and other individualization. The new menu should be tested first in some educational institutions, and after adjustment by the developers, it is recommended for implementation. For the effective organization and implementation of school meals, a systematic approach to the issue of the formation of high-quality raw materials and a flexible pricing policy is required

Cobalt oxide nanosheet and CNT micro carbon monoxide sensor integrated with readout circuit on chip

100學年度研究獎補助論文[[abstract]]The study presents a micro carbon monoxide (CO) sensor integrated with a readout circuit-on-a-chip manufactured by the commercial 0.35 μm complementary metal oxide semiconductor (CMOS) process and a post-process. The sensing film of the sensor is a composite cobalt oxide nanosheet and carbon nanotube (CoOOH/CNT) film that is prepared by a precipitation-oxidation method. The structure of the CO sensor is composed of a polysilicon resistor and a sensing film. The sensor, which is of a resistive type, changes its resistance when the sensing film adsorbs or desorbs CO gas. The readout circuit is used to convert the sensor resistance into the voltage output. The post-processing of the sensor includes etching the sacrificial layers and coating the sensing film. The advantages of the sensor include room temperature operation, short response/recovery times and easy post-processing. Experimental results show that the sensitivity of the CO sensor is about 0.19 mV/ppm, and the response and recovery times are 23 s and 34 s for 200 ppm CO, respectively.[[incitationindex]]SCI[[booktype]]電子
