Bu jadvaldan ko’rinib turibdiki, avtomobil yo’llari ham boshqa obyektlar singari masshtabga bog’liq holda o’z ko’rinishini o’zgartiradi. Ammo shosselarning ko’tarmada o’tgan qismi generalizatsiyaga uchrab bu holati tasvirlanmay qolgan.
Ob’yekt haqida umumiy ma’lumot
Men avtomobil yo’llari davlat kadastri uchun obyekt sifatida Andijon viloyatining avtomobil yo’llarini tanlab oldim. Andijon viloyati — Oʻzbekiston Respublikasi tarkibidagi viloyat. Andijon viloyati — Oʻzbekiston Respublikasi tarkibidagi viloyat. Fargʻona vodiysining sharqiy qismida. 1941-yil 6-martda tashkil etilgan. Maydoni 4,2 ming km². Aholisi 3 253 501 kishi (2022-yil 1-yanvar holatiga). Andijon viloyatida 14 qishloq tuman, 11 shahar va 95 qishloq fuqarolari yigʻini bor. Temir yoʻl transporti viloyatda asosiy transport turlaridan biri. Uning uz. 2459 km (2000). Viloyatda dastlabki temir yoʻl 19-asr oxirlarida qurilib, keyinchalik undan tarmoqlar davom ettirilgan. Urushdan oldin Asaka — Shahrixon (1931), Uchqoʻrgʻon — Toshkoʻmir (1935) va boshqa temir yoʻllar qurildi. Barcha avtomobil yoʻllarining 6,2 ming km qismi qattiq qoplamali (2000). Havo yoʻllari Andijon shahrini Toshkent, Moskva, Sankt-Peterburg va boshqa shaharlar, shuningdek Kavkaz, Qrim bilan bogʻlaydi. Andijon shahri koʻchalarida, shuningdek Andijon shahridan Kuyganyor shaharchasiga ilgari trolleybus qatnagan. Hozirda jamoat transporti sifatida zamonaviy avtobuslar va boshqa yoʻnalishli marshrutlar faoliyati yoʻlga qoʻyilgan.

Bog'liq jamshidbek1 Dastlabki taglikni yuzasini tayyorlash. Dastlabki taglikni yuzasini tayyorlash fotorezistning taglik materialga adgeziyasiga (yopishqoqligiga) katta ta’sir ko‘rsatadi. Dastlabki taglik qanchalik darajada toza bo‘lsa, fotorezistning yopishqoqligi shunchalik darajada yuqori bo‘ladi.
Planar texnologiyada fotolitografiya jarayonlarini amalga oshirish uchun fotoandozalar qo‘llaniladi.
Fotoandoza (FA) fotolitografiya jarayonining asosiy kuroli bulib, uning yordamida FR katlamini mikrosxema topologiyasiga mos xolda lokal yoritiladi.
FA - ultra binafsha nurni yaxshi utkazuvchi ishchi yuzasiga mikrosxemaning malum bir katlami topologiyasiga mos keluvchi plenkali (yoruglikni utkazmaydigan) rasm xosil kilingan tekis plastina yoki egiluvchan polimer plenkadir. FA tayyorlash uchun optik borosilikat shisha yoki polimer plenka ishlatiladi.
Plenkali rasm xosil kilish uchun kumush- galoidli fotoemul’siyadan foydalanilsa metall FA deyiladi va kurinuvchi yoruglikni kisman utkazuvchi oksidlar yoki boshka materiallar plenkasi foydalanilsa rangli FA lar deyiladi.
FA larni yarim utkazgich plastinasiga tez- tez jipslashtirish natijasida u yediriladi. Emulsion FA lar 20 ta operatsiyaga yariydi, metall FA lar 500 ta operatsiyaga yaraydi.
FA tayyorlashning bir kancha usullari mavjud. Optik mexanik usul bilan FA tayyorlash uchun oreginal rasmni 100-1000 marta kattalashtirib yoruglik utkazmaydigan lak surilgan oynaga chiziladi. Lakni kesish uchun olmasli yoki karbid volframli keskichdan foydalaniladi. Oreginal rasm utuvchi yoruglikda (tiniklikni oshirish uchun) 50÷100 marta kichraytirib fotoplastinkaga rasmga olinadi.

Bog'liq jamshidbek1Fotorezistlar. Fotorezistlar (FR) kislota va ishkorlarga chidamli, ma’lum tulkin uzunligidagi yeruglikka sezgir moddalardir.
YEruglik ta’sirida eruvchanligi ortuvchi FR lar pozitiv FR lar deyiladi, aksincha yeruglik ta’sirida erimaydigan xolatga utuvchi FR lar negativ FR lar deyiladi.
Pozitiv FR dan foydalanilganda FSh dagi rasm yarim utkazgichli plastinada xuddi shunday xosil buladi.
Negativ FR dan foydalanilganda rasmning aksi xosil buladi.
Yarim utkazgichli IS lar texnologiyasida negativ FR sifatida polivinil sinnamat (PVS)- polivinil spirti murakkab efiri va korichna kislotasi ishlatiladi. Yoruglikka sezgirlik soxasi ultra binafsha nur. Poroshok shaklida bulib ok yoki sarik ranga ega. Organik eritgichlar toluol+xlorbenzol, atsetat metilinglikol+metoksilol aralashmalarida eriydi.
FR katlamining kislotaga chidamliligi HF va HNO3 kislotalarida katta emas. Ximoyalovchi FR katlami kalinligi 0,5 mkm bulganda kremniyda yemirish mumkin bulgan chukurlik 10 mkmdan, germaniyda 40 mkmdan oshmaydi.
Planar texnologiyasida PVS FR ti SiO2 katlamini yemirgichdan ximoya kilish uchun ishlatiladi.
Pozitiv FR sifatida 1,2-naftoxinandiazit (2)-5-novolak sulfo efirining turli polimerlaridan iborat aralashma ishlatiladi. Eritgich sifatida spirtlar, ketonlar, aromat uglevodorodlar, dioksan ksilol ishlatiladi. NXDA- naftoxinandiazit FR tining yoruglikka sezgirligi ultra binafsha yoruglikda PVS FR tiga nisbatan katta tulkin uzunligi tomonga surilgan. FR ning asosiy parametrlari:
- yoruglikka sezgirligi: xosil kilingan shaklning anikligi.
- ajratish kobilyati: FR yordamida 1mm da xosil kilish mumkin bulgan chiziklar soni.
- kislotaga chidamliligi: ayrim nuktalar va kirralarning kislotada yemirilish darajasi bilan baxolanadi.

Windows 2000 - What is the history of Microsoft Windows

Windows 2000
Windows 2000 was released as an update to Windows NT 4.0. It is not an upgrade to Windows 98 or 98SE.
Windows 2000 builds on Windows NT and offers the following improvements:
-
Full 32-bit operating system
-
Support for NTFS or FAT32, with support for hard disk drives as big as 32GB when running FAT32
-
Windows File Protection, which prevents installed applications from deleting necessary system files
-
Elimination of many reboot scenarios, including program installations that require a reboot to function correctly
-
Support for up to 4GB of Random Access Memory (RAM)
-
Microsoft Management Console (MMC)
-
Stronger Internet integration with Internet Explorer 5.0.1
There are three different versions of Windows 2000: Professional, Server, and Advanced Server. Professional was designed for desktop and laptop systems, both stand-alone and networked, for individual use. Server was designed to run file and printer servers. Advanced Server was designed to run more powerful servers; it has support for an additional 4GB of RAM (for a total of 8GB).
Windows XP
Released in late 2001, Windows XP was the replacement for both the 95/98 and NT families of Windows. Based on the same code used to create Windows 2000, XP came in two workstation versions at launch: Home and Professional. Both versions incorporate the features of Windows 2000. Since its original release, three new editions of Windows XP have been released. These include Media Center Edition, Tablet PC Edition, and XP Professional x64 (64-bit) Edition.
Note: If you want to upgrade an older version of Windows to XP, UITS recommends a clean install rather than a traditional upgrade, due to the strong underlying differences between the older family of operating systems and Windows XP.

Conclusion
In this project, we successfully implemented a system that reads temperature data from a TMP36 sensor, displays it on an LCD1602 display, and uses a buzzer to alert when the temperature increases or decreases. This project combines several fundamental components and techniques in electronics and programming, demonstrating how microcontrollers can be used to create practical and interactive systems.
By combining these components, we created a system that not only monitors temperature but also provides real-time feedback and alerts, making it a practical solution for various applications. This project showcases the importance of integrating multiple technologies to build comprehensive and effective monitoring systems.

Windows NT

Note - What is the history of Microsoft Windows

Windows NT
Note: For security and support reasons, UITS recommends using Windows 2000 Professional or Windows XP Professional, rather than NT Workstation 4.0, on Indiana University's network. Microsoft retired both mainstream and extended support for this version in June 2004, which means security updates are no longer being developed. For more information, see Microsoft's Windows Desktop Product Lifecycle Guidelines page at:
http://support.microsoft.com/?LN=en-us&pr=lifecycle
Windows NT is a separate product from Windows 3.x, Windows 95, and Windows 98. It is aimed at the enterprise market, for use on high-end workstations and servers. The first version, 3.1, and versions 3.5 and 3.51, used the same interface as Windows 3.1. Version 4.0 uses the interface first introduced with Windows 95.
Windows NT 4.0 offered the following new features:
-
NTFS file system support
-
Security model
-
Remote Access Server (RAS)
-
OS/2 and POSIX subsystems
-
Ability to run on Intel, Alpha, MIPS, and Motorola processors
Windows NT 4.0 comes in two versions: Advanced Server and Workstation. The Advanced Server version comes with additional software that allows it to perform the role of the enterprise server. It has the following features in addition to those found on the Workstation version:
-
Software for controlling and managing domains
-
Internet Information Server (IIS)
-
Support for Microsoft BackOffice products
-
DHCP, DNS, and WINS server software

Kirish
Optik tolalarni funksional qurilmalar bilan o‘zaro ishonchii ulash tolali optik aloqa liniyalarini tashkil etishning eng muhim masalalaridan biri hisoblanadi.
Optik ulagich optik aloqa liniya traktining turli komponenta- larini ulash uchun mo'ljallangan qurilma bo‘lib, undan uzatuvchi va qabul qiluvchi optoelektron modullarni optik kabel tolalari bilan, shuningdek, kabelning qurilish uzunliklarini bir-biri ulash uchun foydalaniladi.
Tolali optik ulagichlar va ularning turlari
Optik ulagichlarning ikki — ajralmaydigan va ajraladigan turlari mavjud.
Ajralmaydigan optik ulagichlar kabel tizimlarini doimiy montaj qilish joylarida qo'llaniladi va bu turdagi ulash optik tolalarni o‘Zaro payvandlash usuli bilan amalga oshiriladi. Ajraladigan optik ulagichlar (ularni ko'pincha konnektor deb ham ataladi) optik aloqa liniyalari komponentalarini ko‘p martalab ulash/ajratish uchun ishlatiladi. Amaliyotda ajraladigan optik ulagichlar optik kabelning ikki uchini uzatuvchi va qabul qiluvchi optoelektron modullarning asosiy elementlari — yorug‘lik manbayi va fotoqabulqilgichlar bilan ulashda, ajralmaydigan optik ulagichlar esa optik tolaning oraliq bo'laklarini ulashda qo'llaniladi. Buning sababi shundaki, ajralmaydigan optik ulagichlarda ular tomonidan kiritiluvchi yo‘qotishlar sathi nisbatan past bo‘lib, uning son qiymati 0,04 dB ni tashkil etadi. Bundan tashqari, ajralmaydigan optik ulagichlar ulanishlarda aniq doimiylikni ta'minlaydi. Ajraladigan optik ulagichlarda esa kiritiluvchi yo'qotishlar sathi nisbatan katta bo‘ladi. Bu turdagi optik ulagichlardan, yuqorida qayd etilganidek, bir necha va ko'plab marta ulash-ajratish taqozo etiladigan hollarda, masalan, kommutatsiya panellarida yoki optik kanallarni krosslash maqsadlarida foydalaniiadi.
Agar biz ulovchi qurilmani almashtirishni istasak, unda buni ajralmaydigan optik ulagichlarga qaraganda ajraladigan optik ulagichlar orqali amalga oshirish qulay.

Bog'liq jamshidbek1Fotorezistlarning ruxsat etilganlik imkoniyati. Yarim o‘tkazgichli asboblar va integral mikrosxemalarni ishlab chiqarishda fotorezistlarning qo‘llanish mezonlari deganda tasvirning mikrorelefini minimal o‘lchamdagi elementlarini yaratish imkoniyati tushuniladi. Fotorezistning ruxsat etilgan kengligi fotolitogafiya jarayonini amalga oshirish natijasida plastina sirtida 1 mm o‘lchamda bir xil qalinlikdagi bir-biriga kirishib ketmagan xoldagi o‘tkazilgan chiziqlar soni bilan aniqlanadi. Taglik sirtida l kenglikdagi fotorezist chizig‘ini xosil qilish kerak bo‘lsin. Chiziqlar orasidagi minimal o‘lcham chiziqning qalinligiga tengligini xisobga olgan xolda ruxsat etilganlik imkoniyatini quyidagi ifoda orqali aniqlashimiz mumkin:
Agar yarim o‘tkazgichli asbob yoki mirosxemani tayyorlash uchun l=1 mkm ga teng bo‘lgan minimal o‘lchamli tasvir relefi kerak bo‘lsa, fotorezistning ruxsat etilganlik imkoniyati R=1/(2*0.001)=500 chiz/mm ga qiymatga ega bo‘ladi.
Fotolitografik jarayonning nosozliklarini aniqlashni tadqiq qilish
Fotorezist yordamida fotoandozadan dastlabki taglikka tasvirni ko‘chirib o‘tishni kontaktli fotolitografiyadan tashqari proyeksion optik fotolitografiya yordamida amalga oshirish mumkin. Proyeksion fotolitografiyada fotoandozani taglik bilan kontaktlash operatsiyasi qo‘llanilmaydi. Bu xolatda fotoandozalarning chidamliligi nazariy jixatdan cheksiz bo‘lib qoladi.
Fotolitografiyaning proyeksion usuli kontaktli fotolitogafiya usulida duch kelinadigan kamchiliklarni bartaraf etish imkoniyatini beradi. Proyeksion usulda fotoandozadan tasvirni taglik yuzasiga ko‘chirib o‘tish maxsus yuqori imkoniyatga ega bo‘lgan ob’yektiv yordamida proyeksiyalanadi( 8.1-rasm. Optik proyeksion fotolitografiya sxemasi.
Kontaktli fotolitografiyada dastlabki monokristall taglikda tasvirni xosil qilish jarayonini fotorezist yordamida amalga oshirish ishlari ko‘rib chiqiladi. Bu jarayon fotoandoza va monokristall taglik o‘rtasida kontaktni, ya’ni aloqani, bog‘lanishni o‘zida mujassamlashtirgan va shuning uchun xam kontaktli fotolitografiya deb yuritiladi.
Fotolitografiyani planar texnologiyada qo‘llash bitta taglikda juda xam ko‘p sonli (o‘n yoki yuz minglab) diskret elementlarni va murakkab sxemalarni olish imkoniyatini beradi.
Kontaktli fotolitografiya texnologik jarayoni 8.2- rasmda keltirilgan va u quyidagi operatsiyalarni o‘z ichiga oladi:
Dastlabki taglikni yuzasini tayyorlash;
Taglik ustiga fotorezist qatlamini o‘tqazish;
Fotorezisstni birinchi quritish- plyonka xosil qilish;
Fotoandoza tasvirini dastlabki taglikka qoplash;
Fotorezistni kontakt usuli bilan eksponirlash;
Fotorezistni ko‘rintirish;
Fotorezistni ikkinchi quritish- polimerlash;
Fotorezist plyonkasida tasvir relefini nazorat qilish;
Taglikni yedirish;
Fotorezist plyonkasini taglik sirtidan olish;
Taglikdagi tasvir relefini nazorat qilish.

Yarimo‘tkazgich asboblar va integral mikrosxemalar texnologiyasida fotorezistni qo‘llanilganida zaruriy e’tiborga olinadigan mezonlar yorug‘likka sezgirlik, ruxsat etilganlik imkoniyati, kislotabardoshlik va ishlov berishga qulaylik xisoblanadi.
Fotorezistlarning yorug‘lik sezuvchanligi. Istalgan fotorezistning yozug‘liksezuvchanligi eksponirlash va ko‘rintirish jarayonining funksiyasi xisoblanadi. Eksponirlash jarayonining asosiy talabi fotorezistning spektral sezgirligidir, bundagi qiymat yutilib qaytgan yorug‘lik energiyasi bilan aniqlanadi va bu yorug‘lik sezgir materialning xossalarini o‘lchash aniqligi uchun kerak bo‘ladi.
Fotorezistning spektral sezgirligi quyidagi formula orqali aniqlanadi:
Bu yerda YE- fotorezistning yorug‘lik nurlanganligi, Vt/m2; t-nurlanish vaqti, s; H=Et-ekspozitsiya qiymati, Bt*s*/m2.
Bundan ko‘rinib turibdiki, fotorezistlarning yorug‘lik sezgirligi yorug‘lik sezuvchan material qatlamining to‘liq yoritilishi bilan bog‘liq. Fotolitografiya jarayonida faqatgina yorug‘lik sezgir materialning to‘liq yoritilishi emas, balki yuqori sifatli fotorezist qatlamini , ya’ni tasvir relefini xosil qilish bu jarayonning asosiy maqsadi xisoblanadi.
Shuning uchun fotorezistlarning yorug‘lik sezuvchanlik xarakteristikalarini to‘liqroq tarzda ikkita jarayonni, ya’ni ekspozitsiya va ko‘rintirish jarayonlarini birgalikda ko‘rish orqali tushuntirish mumkin. Ko‘rintirish jarayoni fotorezistlarning yorug‘lik sezuvchanligiga to‘g‘ridan-to‘g‘ri ta’sir ko‘rsatadi, ya’ni xosil bo‘lish jarayonida ta’sir etuvchi bilan fotorezist plyonkasining eksponirlangan va eksponirlanmagan oblastlari o‘rtasida o‘zaro ximiyaviy ta’sirlashuv sodir bo‘ladi. Ko‘rintirish jarayoni fotorezist plyonkasida ma’lum tasvir relefini shakllantiradi va bu olingan tasvir relefi xosil qilingan ximoya plyonkasini sifatini aniqlab beradi.
Negativ fotorezistlarning yorug‘lik sezuvchanlik mezoni deganda taglik yuzasida eksponirlash va ko‘rintirish jarayonlari amalga oshirilgandan keyin fotorezist plyonkasining lokal polimerlangan uchastkalarini (tasvir relefini) xosil qilish tushuniladi.
Pozitiv fotorezistlarning yorug‘lik sezuvchanlik mezoni deganda butunlay yemirilish va taglik yuzasida eksponirlash va ko‘rintirish jarayonlari amalga oshirilgandan keyin fotorezist plyonkasining lokal uchastkalarini (tasvir relefini) yo‘qotish tushuniladi.
