    Nutq signallarini fonetik tahlil qilish algoritmlari

    Ibragimova S. N.,

    Mavzuning dolzarbligi va dissertatsiya tadqiqotiga bo‘lgan ehtiyoj. Jahonda zamonaviy raqamli texnologiyalar va sun’iy intellektning rivojlanishi nutq signallarini avtomatik tahlil qilish va qayta ishlash vazifasini eng dolzarb yo‘nalishlardan biriga aylantirilgan. Nutq insoniy muloqotning asosiy vositasi hisoblanadi, uni avtomatik qayta ishlash esa ta’lim, tibbiyot, multimedia tizimlari hamda intellektual interfeyslar sohalarida yangi istiqbollarni ochib beradi.

    Ba'zi biomolekulyar komplekslarning elektro-optik xususiyatlari va tebranish spektrlari

    Xolikulov O'. A.,

    Dissertatsiya mavzusining dolzarbligi va zarurati. Jahon ilm-fanida biomolekulyar komplekslarning elektro-optik xususiyatlari va tebranish spektrlarini o‘rganish molekulyar optika, biofizika va fizikaviy kimyo sohalarida muhim yo‘nalish hisoblanadi. Ushbu tadqiqotlar biomolekulalar va ularning komplekslaridagi molekulalararo ta’sirlarni (vodorod bog‘lanish, elektrostatik ta’sirlar, van der Vaals kuchlari) tushunishga yordam beradi, bu esa biologik jarayonlarning molekulyar mexanizmlarini aniqlashda asosiy rol o‘ynaydi.

  • Bilimni qayta ishlash algoritmlari
    Dissertatsiya

    Bilimni qayta ishlash algoritmlari

    Rustamov E. N.,

    Dissertatsiya mavzusining dolzarbligi va zarurati. Jahonda intellektual texnologiyalarning samarali rivojlanishi bilimlarni qayta ishlash algoritmlarini yaratishni talab qiladi. Aynan shu algoritmlar ma‘lumotlarni tizimlashtirish, talqin qilish va barqaror semantik tuzilmalarga aylantirishni taʻminlashi lozim. Agar bilimlar bazasi predmet soha ma‘lumotlaridan qatʻiy belgilangan qoidalarga asoslanib shakllantirilgan boʻlsa, diagnostika, monitoring, boshqaruv, tibbiy va texnik yechimlar kabi murakkab amaliy masalalar muvaffaqiyatli yechiladi.

    Photogrammetric techniques for the functional assessment of tree and forest resources in Khorezm, Uzbekistan

    Alexander Tupitsa.,

    The extent, diversity and dynamics of a land cover have to be understood to develop management concepts for tree and forest resources in Uzbek drylands. Owing to inapplicability of extensive terrestrial surveys, reliable and up-to-date inventories of natural forests and tree plantings are lacking in Uzbekistan. Based on aerial photographs, a comprehensive assessment of hedgerows and windbreaks, tree plantations and natural floodplain (“tugai”) forests was carried out. Recommendations on the extension of tree plantings within croplands to improve growing conditions of crops and produce useful by-products as well site-specific measures for protecting and restoring the tugai forest ecosystem are given.

  • Improving the nitrogen use effeciency and crop qualiti in the Khorezm region,Uzbekistan.

    Improving the nitrogen use effeciency and crop qualiti in the Khorezm region,Uzbekistan.

    Kirsten Maren Kienzler,

    Low nitrogen fertilizer use efficiency in irrigated cotton and winter wheat constrains yields and farm income in Uzbekistan. Therefore nitrogen use inefficiencies under farmers’ production practices were quantified and compared to those obtained with higher or lower nitrogen application rates, different fertilizer types and application times. Also the crop quality was assessed for the different practices. Modifications particularly in the timing of the application, e.g. at budding in cotton or an additional dose at wheat heading, could increase the nitrogen use efficiency, help reduce nitrogen losses and thus the cost of fertilizer application. This would render agriculture more environmentally sound.240
