In this research, the strength and deformation states of thin plates made of two-layer composite materials are presented. The first layer of two layer thin plates consists of metal or reinforced concrete layers, the thickness of which is much higher than the thickness of the second composite layers. Layers differ in physical and mechanical properties and thicknesses and are made of metal or reinforced concrete materials
So‘nggi yillarda hujjatlarni raqamlashtirish tendensiyasi paydo bo‘ldi. Dunyoning raqamlashuvi jarayonida qog‘ozga asoslangan hujjatlarni yanada qulayroq, qidirish va saqlash uchun raqamliga aylantirish zarur. Elektron hujjatda (EH) qatorlar matn maydoni to‘plamiga taqsimlanadi. Boshqacha qilib aytganda, satr bir nechta segmentlarga bo‘linib, har bir segment boshqa to‘plam matn maydoniga joylashtirilishi mumkin. Shuning uchun matn satr bilan samarali bog‘langanligi bois to‘plamdagi har bir matn bog‘langan matn maydoni deb ataladi. Shuningdek satrning butun mazmunini o‘z ichiga olgan hamda boshqa matn maydoni bilan bog‘lanmagan matn maydonini himoyalangan matn maydoni deb ham atalishi mumkin.

The paper proposes a method for synthesizing an adaptive fuzzy synergistic controller with discrete time for indefinite nonlinear dynamic objects, with changing parameters in time. The synthesized adaptive controller takes into account the non-linear nature of the object, allows its parameters to adapt to environmental changes: The synthesis of the controller is carried out by the hybrid application of the methods of the theory of synergistic control and fuzzy system and gives the system asymptotic stability and t d the desired dynamic properties of the control system, with the ability to adapt to changes in the parameters of the object. The proposed method of synergistic control guarantees the reliability and asymptotic stability of the control system and makes it possible to use typical and atypical control laws. To overcome the difficulties associated with the uncertainties of the function of the states of objects, the use of a neural network model of the Mamdani Type is proposed. A sigmoidal function is used as t the membership function, which is distinguished by the simplicity of implementation and the possibility of differentiating input wariables. The resulting control law has an analytical dependence, which significantly increases the possibilities of its implementation on microcontrollers. The simulation results by example showed the effectiveness of t of the proposed method relative to the known ones
During the research, the use of piece-polynomial methods in digital processing of images was considered. The Hermite spline function is chosen from piece-polynomials as a mathematical model in digital processing of signals, and the construction of a two-variable third-order Hermite spline function is presented. An image restoration algorithm was developed based on the constructed mathematical model.
Maqolada qishloq xo‘jaligi yerlaridan oqilona foydalanishni tashkil etishning zamonaviy muammolari keltirilgan. Qishloq xo‘jaligi yerlaridan foydalanish amaliyotining kamchiliklari va qishloq xo‘jaligi yerlarini boshqarish tizimining funksiyalari tarkibi aniqlandi. Qishloq xo‘jaligidan foydalanishning asosiy muammolarini zaif agrar siyosati, yerni boshqarish tizimining yo‘qligi, yerni boshqarishning ayrim funksiyalarining rivojlanmaganligi, qishloq xo‘jaligi ishlab chiqaruvchilarining moliyaviy ba’zasining zaifligi, agrobiznesning jiddiy xavflari deb atashadi. Yerdan foydalanishni tashkil etish muammolarini hal qilish bo‘yicha takliflar asoslanadi qishloq xo‘jaligi maqsadlari: qishloq xo‘jaligi yerlarini boshqarishning samarali tizimini tiklash; yerni boshqarishning asosiy funksiyasi sifatida yerni boshqarishni loyihalash amaliyotini tiklash imkoniyatini ta’minlash; yerlarning holatini samarali monitoring qilish va yer fondidagi sifat o‘zgarishlarini baholash tizimini yaratish; qishloq xo‘jaligi ishlab chiqaruvchilarini moliyaviy qo‘llab quvvatlash, belgilangan yer massivlaridan oqilona foydalanish; qishloq xo‘jaligining investitsion jozibadorligini oshirish.
The present article seeks to explain the impact of the processes globalization on national cultures and the response of ethnic cultures to such processes from the viewpoint of alternate progress theories. The immanent connection between globalization and ethno-cultural diversity, proximity and national-cultural models of alternative development are the object of our research.In the current period, the communicative function of culture has expanded dramatically, transformation processes are taking place in it in accordance with global changes. In particular, forms of indirect communication (mobile phone, Internet) are making radical changes in this function. Now there is rapid rapprochement of cultures, exchange of experience and mutual enrichment. At the same time, it is necessary that the communicative function does not harm the diversity of ethno-cultures, does not interfere with intercultural communication in accordance with national interests, and especially does not focus on the decision-making of Western popular culture. No matter how much international dialogue and integration help to establish universal values and norms, they should not serve to make a culture in a mood of expansion become a dominant force.During the period of democratic reforms, scientific and practical research was started on the restoration of Uzbek ethnic culture, the use of its historical, educational and artistic-aesthetic possibilities. The state is leading the development of many types of folk creativity and art. However, comprehensive research of Uzbek ethnic culture, its genesis, sociological and axeological foundations, integration relations with the culture of sister nations, and comparison with other ethnic cultures in the system of these relations is one of the tasks before us. Philosophical studies conducted today are mainly empirical in nature, philosophical generalizations are rare in them. Therefore, there is a scientific-theoretical need to study cooperation, communication and integration between ethnic cultures under the influence of globalization from a philosophical point of view, without forgetting the allogenesis and ideogenesis of ethnic culture. It should focus not only on making philosophical generalizations, but also on finding ways to effectively use artistic-aesthetic possibilities, tools, and artifacts.
