Axborotni ma’lum bir model asosida uzatish lozim

22
Agar axborot xulosa qilishga yеtarli bo‘lsa, u
to‘liq
bo‘ladi. To‘liq
bo‘lmagan axborot xato xulosa va harakatlarni keltirib chiqaradi. Masalan,
«Ko‘chada temperatura 10 daraja
» kabi xabarda
issiq
yoki
sovuqligi
aytilmasa,
inson ustki kiyimni noto‘g’ri tanlashiga olib keladi.
Agar axborot hozirgi paytda zarur bo‘lsa, u
dolzarb
bo‘ladi. Masalan,
do‘stlar kelishi haqidagi telegramma o‘z vaqtida ularni kutib olish imkonini beradi.
Eskirgan, bevaqt yoki ahamiyatsiz axborot inson uchun dolzarb bo‘lmaydi.
Inson tushunarli bo‘lgan tilda bayon etilsa, axborot
tushunarli
bo‘ladi.
Masalan, ispan tilini bilmagan insonga ispan tilida xat yozilsa, bu
tushunarsiz
bo‘ladi.
Olish imkoniyati bo‘lganda axborot ochiq bo‘ladi. Turli to‘siqlar axborotni
yopiqqa aylantirishi mumkin. Masalan, arxivdagi maxfiy hujjatlarni bu arxivga
kirish huquqi bo‘lmagan kishilar ololmaydi. Shu sababli bu kishilar uchun
arxivdagi hujjatlar yopiq hisoblanadi.
Har bir inson o‘zi uchun olingan axborot foydali va muhim ekanligi haqida
hukm chiqaradi. Axborotning asosiy xususiyatlarini bilish insonga olingan
axborotni to‘g’ri baholash hamda to‘g’ri qaror qabul qilishga yordam beradi.
Inson doimiy ravish atrof muhitdan axborot oladi, uning xususiyatlarini
tahlil qiladi, muhim qonuniyatlarni aniqlaydi va buning ortidan dunyoni bilib oladi.
Axborotni tushunish, uni tahlil qilish va amaliyotda qo‘llash orqali insonda
bilimlar shakllanadi. Bir axborot turli insonlarda turlicha bilimlarni keltirib
chiqarishi mumkin. Shakllangan bilimlarni inson o‘z faoliyatida qo‘llaydi. Ayni
damda inson faoliyati uning atrof muhit haqidagi bilimlarining ko‘payib borishiga
yordam beradi.

....................................................................................................................................................................
DIRECTOR: Now, does she have any medical conditions we need to know about? Does she have asthma
or any hearing problems for example?
CAROL:
No. But
she does need to wear glasses.
Q7
DIRECTOR: Oh, I’ll make a note of that.
CAROL:
Yes, she’s pretty good about wearing them, she can’t see much without them.
DIRECTOR: Right. OK. Now, I also need emergency contact details.
CAROL:
So what sort of information do you need?
DIRECTOR: Just the name and number of a friend or family member we can contact in case we can’t
get hold of you at any time.
CAROL:
OK. That’d better be my sister … Jenny
Ball
Q8
. That’s B-A-double L. Her phone number
is 3346 7523.
DIRECTOR: Great. So
she is the child’s aunt?
Q9
CAROL:
Yes, that’s right.
DIRECTOR: I’ll make a note of that as well. Now, is there anything you’d like to ask?
CAROL:
What about payment? How much are the fees each term?
DIRECTOR: Well, for two days and the hours you’ve chosen, that will be $450 altogether.
CAROL:
OK, and do I have to pay that now?
DIRECTOR: No, we send out invoices once the children start at the centre. You can choose to pay at
the end of each term or we do offer a slightly discounted rate

[ Modulant ]
Burada, T tranzistordir, R rezistor, C kondensator va Modulant moduliatsiya qilingan amplituda signali.
8. SMX (sinus moduliatsiya indeksi) amplituda modulyatsiyasi bilan ifodalangan bo‘lib, SMX = (A_m - A_c) / (A_m + A_c), bu yerda A_m modulyatsiya amplitudasi va A_c asosiy sinyal amplitudasi.
9. Nochizqli elementning vax asosida SMX ni olish uchun analitik uslubda quyidagicha formuladan foydalanasiz: SMX = (v_max - v_min) / ( v_max + v_min), bu yerda v_max maksimum bo‘ladigan signaldagi amplituda, v_min esa minimum bo‘ladigan signaldagi amplitudaning o‘rtacha qiymatlari.
Grafik uslubda esa, am signalning modulyatsiya qilingan signaldan uchilgan shakllarini ko‘rib chizganingizda SMX ni olishingiz mumkin.
10. SMX asosida tranzistorning ish rejimi SMX<1 bo‘lgan paytda tanlanadi, chunki bu tartibda tranzistor harmonik modulyatsiya qilingan amplituda signallarini yaroqlanishi mumkin.
11. Siljish kuchlanishi qiymatining o‘zgarishi am signalning shakliga qarab tanlanadi, ya'ni kuchlanish qiymati amplituda modulyatsiyasi koeffitsiyentiga bog‘liq bo‘ladi.
12. Tebranish konturi rezonans chastotasining yuqori chastotali tashvish uchunmosligi AM signal shakliga mos keladi. Bu holatda, tebranish konturiga yuqori chastotali tashvish berar xisoblanadi va AM signali xisobotda uni buzib turadi.
13. Tranzistor yuklamasida aperiodik rezistor (R) bo‘lganda sifatli AM olish mumkin. Aperiodik o‘zgaruvchanlik, amplitudasi va chastotasining statistik qirraligiga ega bo‘lmagamdir.
14. Tranzistor yuklamasi tebranish konturi asilligi (dobrotnost), amplituda modulyatsiyasi koeffitsiyentiga ta’sir qiladi. Bu asillik kattalashti, AM olinadigan kuchi kattalashgan bo‘ladi.
4-amaliy mashg‘ulot.
AM signallarni hosil qilish va detektrlashni amaliy o‘rganish.
Ishdan maqsad: talabalarga joriy mavzuga oid bilimlarni berish hamda tegishli qurilmalar, uning ish tamoyili hamda signallarini shakllantirish shuningdek ularni qayta ishlash prinsiplarini o‘rgatishdan iborat.
Topshiriq: joriy mavzuga oid bilimlarni shu ko‘rsatmaga asosan mustahkamlash, tegishli tizim bo‘lsa u auditoriyada bo‘lsa to‘g‘ridahto‘g‘ri o‘qituvchiga o‘z xulosa va bilimlarini namoyon etish xam hisobotlar tuzishdan iborat.

in the 1930s those governments were worried about people’s general health

in the 1930s those governments were worried about people’s general health,
because everyone was suddenly buying canned fruit, artificial butter, meat in tins...
that kind of thing.
Q23
It became very common. And so newspapers were featuring lots of
government reports about how serious this was.
Lucy:
I see.
Sam:
And then, some people saw a business opportunity.
Lucy:
Naturally.
Sam:
In the 1940s, companies started making and selling vitamin supplements in bottles. And they
decided the easiest way to market them was to target housewives.
Lucy:
Why was that? Because housewives were responsible for keeping families healthy?
Sam:
I’d say so.
In the weekly magazines housewives read, the companies made exaggerated
claims about what the supplements could do, and they showed pictures of rats in a
laboratory before and after they were given vitamins. The ‘before’ pictures showed
the rats looking very sick.
Q24
Lucy:
So they scared the housewives into buying their product.
Sam:
Apparently.
Lucy:
But vitamins were still expensive, weren’t they? It wasn’t until the 1950s that more people
could afford to buy them.
Sam:
Why was that?
Lucy:
Well manufacturers had discovered how to produce vitamins artificially and in enor-
mous quantities in their factories.
Q25
Sam:
I suppose that’s what goes on with any product. It starts expensive until manufacturers
adapt their technology. Were there any developments in the 1960s?
Lucy:
Companies changed their promotional strategy to increase their sales.
They used movie
stars to say how effective the supplements were.
Q26
Sam:
That’s still true today. Celebrity endorsement really seems to work. Someone on the TV
says vitamins have made them healthier and immediately more consumers go out and buy
them.

Axborot bilan inson tug’ilishi bilanoq to‘qnashadi

23
Yechim qabul qilish uchun
(biron-bir ishni qilishdan avval inson nimani va
qanday qilishini aniqlab olishi kerak);
Rivojlanish uchun
(axborotni qabul qilib va u bilan
ishlab inson xotira va
aqlni rivojlantiradi);
Ehtiyojlarini qondirish uchun
(insonga qiziqarli kitob,
chiroyli musiqa,
rasm, sportchilarning hayajonli janglari kerak).
Axborot nafaqat inson hayotida, balki butun insoniyat jamiyati hayotida
muhim o‘ringa ega. Jamiyat mavjudligining asosi
axborot almashinishdan
iborat.
Axborot almashinish tufayli jamiyat alohida jamiyat a’zolarini birlashtira
oladi. Agar insoniyat jamiyatini nazarda tutsak,
ijtimoiy jamoa tuzumidagi
odamlarning birgalikda ovga chiqishlari bir-birlari bilan axborot
almashinishlari orqali amalga oshgan. Axborotning birlashtiruvchilik roli
hozirgi kunda ham o‘zgargani yo‘q – insonlarning
katta jamoasini maqsad
sari yo‘naltirishning boshqa usuli yo‘q (axborot almashishdan tashqari).
Axborot jamiyat hayotida boshqarish uchun qo‘llaniladi. Jamiyat hayotining
turli tomonlarini boshqarish uchun bir necha axborot vositalari
(qurilmalari) yaratilgan. Oddiy misol – yo‘l svetofori – harakat
qatnashchilariga avtomatik tarzda ma’lum bir rangdagi
signallarni yuborib
yo‘l harakatini boshqaradi.
Insoniyat jamiyatiga xos xususiyatlardan biri – avloddan
avlodga axborotlarni
uzatish va to‘plashdan
iborat.
Zamonaviy ilm-fandan
Inson miyasi doim ishlaydi – kunduzi hissiyot
organlaridan olgan signallarni qabul qiladi va qayta
ishlaydi, kechqurun esa miya faoliyati natijasida tushlar

tahlil etilib, galdagi vazifalar belgilab olinishi yaxshi an’anaga aylangan.
O‘zbek adabiy tili turkiy tillar guruhiga mansub bo‘lib, u mustaqil til
sifatida XI asrdan boshlab shakllana boshladi va to hozirgi kunimizgacha bu
tilda
ko‘plab ilmiy va badiiy asarlar yaratildi. Xususan, Mahmud Qoshg’ariyning
“Devonu lug’otit-turk”, Yusuf Xos Hojibning “Qutadg’u bilig”, Xorazmiyning
“Muhabbatnoma”, shuningdek, Atoiy,
Sakkokiy, Sayfi Saroiy, Mavlono, Lutfiy,
Alisher Navoiylarning yaratgan boy ilmiy-adabiy meroslarini tilga olish mumkin.
Til — millatimiz faxri, g’ururidir.

CAROL:
I need to get to work in the city by 9:00 so
I’ll drop her off at 8:30
Q4
. You’re pretty close
to the city here so that should give me plenty of time to get there.
DIRECTOR: That’s fine. Now, we also need to decide which group she’ll be in. we have two different
groups and they’re divided up according to age. There’s the green group. Which is for three-
to four-year-olds. And then there’s the red group which is for four- to five-year-olds.

Keltirilgan qiymatlar davriy E.Yu.K., kuchlanish va toklarning joriy (amaldagi) qiymatlari deb ataladi.
Quyida ushbu tanlashni asoslovchi fikrlarni keltiramiz. Masalan, bir davr ichida r qarshilikka ega zanjirda issiqlik ajralib chiqishini kursatuvchi o‘rtacha quvvat miqdori quyidagi ifoda orqali topiladi:
1 Т i 2 r dt r 1 Т i 2 dt r I 2
(10.10)
Т 0 Т 0
Binobarin, davriy effektiv tok tushunchasini kirita turib (to‘liq davr ichidagi uning o‘rta kvadratik qiymatiga teng bo‘lgan), ushbu tok orqali ifodalangan, ko‘rinishdan huddi o‘zgarmas toklar uchun kabi o‘rtacha quvvatni hisoblash formulasini hosil qilamiz.
Endi effektiv sinusoidal E.Yu.K.ning Ye qiymatini uning amplitudasi Yem bilan bog‘liqligi: ye = Yemsin(t + ψe) ni aniqlaymiz. U holda quyidagicha ega bo‘lamiz:
Е
(10.11)
chunki
Em
Em
T
0 cos(2 t 2 e ) dt 0
Em
(10.12)
Huddi shuningdek, sinusoidal kuchlanish va sinusoidal tok uchun quyidagilarga ega bo‘lamiz:
U Um ;
I Im
(10.13)
Amaliyotda, davriy kuchlanish va toklarni o‘lchash uchun qo‘llaniladigan priborlarning ko‘pchilik qismi ushbu kattaliklarning ta’sir etuvchi effektiv qiymatlarini kursatadi.
To‘liq davr ichida effektiv sinusoidal E.Yu.K., kuchlanish va toklarning o‘rtacha arifmetik qiymati nolga teng bo‘ladi. Shu sababli ularning musbat yarim davr ichida o‘rtacha qiymati tushunchasi kiritiladi (5-rasm).

Sinxron generatorlar turlari va ularning ishlash

Sinxron generatorlar turlari va ularning ishlash tamoyili.
Generatorlar elektr stansiyalarining asosiy elementi hisoblanadi. Zamonaviy elektrostansiyalarda deyarli to‘liq hajmda faqatgina uch fazali o‘zgaruvchan tok generatorlarigina qo‘llanilmoqda. Birlamchi, mexanik harakatni hosil qiluvchi
yuritgichlarga bog‘liq holda ular ikki guruxga: turbogeneratorlar va gidrogeneratorlarga bo‘linadi.
Turbogeneratorlar bevosita bug‘ va gaz turbinalari bilan bog‘langan holda ishlashi sababli ularning asosiy farq qiluvchi belgisi tez aylanishidir, ular yuqori aylanish chastotasiga egadirlar. Turbina aylanish chastotasi qancha katta bo‘lsa, uning chiziqli o‘lchamlari (gabariti) shuncha kichik va mos holda foydali ish koeffisenti shuncha katta bo‘ladi, shu sababli turbogeneratorlar aylanish tezligini imkon boricha oshirishga harakat qilinadi. Ikkinchi tomondan, aylanish tezligini oshirish imkoniyati ham, tarmoqdagi chastota f = 50 Gs ga va generator juft qutblari minimal soni p = 1 ga bog‘liq holda cheklangandir.
U holda quyidagiga ega bo‘lamiz:
n 60 f
P
(10.4)
bu yerda f = 50 Gs - tarmoqdagi chastota (Yaponiya va AQSh da f = 60 Gs) R – juft qutblar soni.
Alohida, maxsusholatlarda kichik quvvatli trubogeneratorlarni trubinalarga bevosita emas, balki pasaytiruvchi reduktor orqali ulanishiga ham yo‘l qo‘yiladi. Bu holatlarda turbinalar yuqori aylanish chastotasiga ega bo‘lishlari mumkin. Ammo ushbu turdagi reduktorlar odatda bug‘ - turbinali GES larda qo‘llanilmaydi, chunki yuqori quvvatli turbogeneratorlar ishlash ishonchliligini pasaytirib yuboradi.
Gidrogeneratorning aylanish chastotasi quyidagi ifoda asosida hisobiy yo‘l bilan aniqlanadi:
nturb =
H 5 / 4
n (10.5)
bunda nb – turbina turiga bog‘liq bo‘lgan tezlik koeffisienti; ayl/minutda; H – bosim, metrda; R – turbinaning quvvati, MVt da.
Ta’rif: Uch fazali sinxron generatorning nominal kuchlanishi deb stator o‘ramidagi U n chiziqli kuchlanishga aytiladi. U n quyidagi qatorni hosil qiladi: 3.15; 6.3; 10.5; 18.0; 20.0; 21.0; 24.0 kV.
Sinxron generatorlarning nominal to‘liq quvvati quyidagi formula bilan aniqlanadi:
S n = U nI n (10.6)
Mos holda, aktiv va reaktiv quvvatlar quyidagi ifodalar orqali aniqlanadi:
Pn = Qn =
Un I n cos φ (10.7)
Un In sin φ (10.8)
bunda cosφ – quvvat koeffisenti, sinφ esa: sinφ =
Turbogeneratorlar uchun nominal quvvat koeffisentining qiymati quvvat 100 MVt gacha bo‘lsa 0.8 ga, 160 –500 MVt bo‘lganda 0.85 ga va quvvat 800 MVt gacha bo‘lganida 0.85 dan 0.90 gacha teng bo‘ladi.
Gidrogeneratorlarning nominal quvvat koeffisenti quvvat 125 MVt va undan kichik bo‘lganda 0.8 ga, quvvat 125 dan 360 MVt gacha bo‘lganda - 0.85 ga va 360 MVt dan yuqori quvvatda 0.9 ga teng bo‘ladi.

MATVAFOYEV IZZATBEKNING KIBERXAVFSIZLIK ASOSLARI FANIDAN
“AXBOROT-KOMMUNIKATSIYA TEXNOLOGIYALARI XAVFSIZLIGIGA BO‘LADIGAN TAHDIDLAR” MAVZUSIDA YOZGAN
MUSTAQIL ISHI
TOPSHIRDI:_______________________________________________
QABUL QILDI:_____________________________________________
REJA:
1. Kirish. Axborot xavfsizligi nima?
2. Asosiy qism
A. Axborot xavfsizligida evolyutsiyasi
B. Bugungi kundagi axborot xavfsizligiggida yutuqlar
D. Sun’iy intelektlarning kiberxavfsizlikdagi o’rni
3.Xulosa.
Axborot xavfsizligi (ba’zan InfoSec deb ataladi) tashkilotlarning axborotni himoya qilish uchun foydalanadigan vositalar va jarayonlarini qamrab oladi. Bunga ruxsatsiz shaxslarning biznes yoki shaxsiy maʼlumotlarga kirishiga toʻsqinlik qiluvchi siyosiy sozlamalari kiradi. InfoSec – tarmoq va infratuzilma xavfsizligidan tortib, sinov va auditgacha bo’lgan keng doiradagi sohalarni qamrab oluvchi o’sib borayotgan va rivojlanayotgan sohadir.
Axborot xavfsizligi maxfiy ma’lumotlarni ruxsatsiz harakatlardan, jumladan, tekshirish, o’zgartirish, yozib olish va har qanday buzilish yoki yo’q qilishdan himoya qiladi. Maqsad – mijoz hisobi tafsilotlari, moliyaviy ma’lumotlar yoki intellektual mulk kabi muhim ma’lumotlarning xavfsizligi va maxfiyligini ta’minlash hisoblanadi.
Xavfsizlik hodisalarining oqibatlari shaxsiy ma’lumotlarni o’g’irlash, ma’lumotlarni buzish va ma’lumotlarni o’chirishni o’z ichiga oladi. Hujumlar ish jarayonlarini buzishi va kompaniya obro’siga putur yetkazishi, shuningdek, sezilarli miqdordagi xarajatlarga olib kelishi mumkin.
Tashkilotlar xavfsizlik choralari uchun mablag’ ajratishlari va ular fishing , zararli dasturlar , viruslar, zararli insayderlar va to’lov dasturlari kabi hujumlarni aniqlash, javob berish hamda faol ravishda oldini olishga tayyor bo’lishlarini ta’minlashi kerak .

Q2
, antiques you know. There are some really lovely things around
here, but you need to get out to the small towns. I’ve had a really good trip this year, until
this happened.
OFFICER: OK. So you’ve been here quite a while?
LOUISE:
Yes, I’m here for two months. I go back next week.
OFFICER: So may I ask where you’re staying now?
LOUISE:
Well at present I’ve got a place at
Park
Q3
Apartments, that’s on King Street. I was staying
at the Riverside Apartments on the same street, but the apartment there was only available
for six weeks so I had to find another one.
OFFICER: OK. And the apartment number?
LOUISE: Fifteen.
LOUISE: Right.
....................................................................................................................................
OFFICER: Now, I need to take some details of the theft. So you said you had some things stolen out
of your bag?
LOUISE:
That’s right.
OFFICER: And were you actually carrying the bag when the theft took place?
LOUISE:
Yes, I really can’t understand it. I had my backpack on. And I went into a supermarket to
buy a few things and when I opened it up my wallet wasn’t there.
OFFICER: And what did your wallet have in it?
LOUISE:
Well, fortunately I don’t keep my credit cards in that wallet – I keep them with my passport
in an inside compartment in my backpack. But there was quite a bit of cash there … about
£
250
Q4
sterling, I should think. I withdrew £300 from my account yesterday, but I did a bit
of shopping, so I must have already spent about £50 of that.
OFFICER: OK.
LOUISE:
At first I thought, oh I must have left the wallet back in the apartment, but then I realised
my
phone
Q5
had gone as well. It was only a week old, and that’s when I realised I’d been
robbed. Anyway at least they didn’t take the keys to my rental car.
OFFICER: Yes. So you say the theft occurred yesterday?

Benzol xalqadagi orientirlanish - Elektrofil urin olish reaktsiyalarida nafakat benzol va uning gomologlari bilan bir katorda boshqa urin bosarlarga ega turli aromatik birikmalar xam ishtirok etadi. Misol qilib nitrat kislotani toluolga ta`sirini keltirsa bo`ladi, bunda 2,4,6-trinitrotol xosil bo`ladi.

Bog'liq 7-tag\'dimotMezomer samara - Ta`sirlangan - sistemalarda urinbosarlar ta`siri ostida elektron zichlikning siljishi tufayli vujudga keladigan elektron samara mezomer samara deyiladi. Agar o`rinbosar o`z tarkibida bo`linmagan elektron juftini tutsa, ya`ni ta`sirlangan sistemada elektron zichlikni oshirsa u musbat mezomer samara (+M) ko`rsatadi. Bunday o`rinbosarlar elektronodonor o`rinbosarlar xisoblanadi va ular qatoriga OH, Hal, OR, NH2 guruxlari kiradi.
Agar o`rinbosar sistemada elektron zichlikni kamaytirsa, u elektronoaktseptor o`rinbosar xisoblanadi. Bunday o`rinbosar o`z tarkibida to`yinmagan guruxlar yoki to`liq musbat zaryad tutadi: NO2, -COH, -COOH, -SO3H va b. Bu guruxlar manfiy mezomer samara (-M) beradi. Mezomer samara qo`sh bog’dan yoki qo`sh bog’ga qaratilib egilgan strelka bilan ko`rsatiladi. elektron samaralar molekulada manfiy yoki musbat zaryadlar qanday taqsimlanganligini va bu molekulaning kimyoviy xossalarini oldindan aytib berishga imkoniyat beradi.
Organik molekulalarning aromatikligi
Xalqali uglevodorodlarda ta`sirlanish fazoda (xalqaning usti va ostida), barcha uglerod atomlarni birlashtiruvchi -sistema (umumiy elektron bulut) vujudga kelishiga olib keladi. Bu bulut xosil bo`lishida Xyukkel’ qoidasiga asosan (4n+2) ta - elektronlar qatnashishi kerak. SHuning asosida xulosa qilish mumkinki, modda aromatik bo`lishi uchun 3 ta qoidaga (mezonlarga) amal qilishi kerak:
yassi xalqaga ega bo`lishi
umumiy -elektron bulutga ega bo`lishi
Xyukkel’ qoidasiga rioya qilishi, ya`ni elektronlar soni (4n+2) formulaga tushishi

Benzol xalqasida alkil gurux bo’lgan vaqtda yadrodagi xolatlarning reaktsion qobiliyai quyidagi tartibda kamayib boradi: o->m->n- bunga sabab alkil gurux, masalan, metil (CH3) benzol yadrosi tomon elektronlarni siljitib, yadrodagi elektron zichlikni oshiradi. Bu ta'sir masofa uzoqlashgan sari kamayib boradi. E
