Bog'liq Bir fazali toʻgʻrilagich qurilmalari2.1.2. To’g’rilagichning chiqish parametrlari
To’g’rilagichning chiqish parametrlariga quyidagilar kiradi:
to’g’rilangan kuchlanishning o’rtacha qiymati Uo;
to’g’rilangan tokning o’rtacha qiymati Io;
to’g’rilangan kuchlanish asosiy garmonikasi pulsatsiyasining chastotasi ftkp;
to’g’rilangan kuchlanishning pulsatsiya koeffitsienti Kp;
to’g’rilagich kirish kuchlanishi bitta qiymatda bo’lganida Uo chiqish kuchlanishining Io yuklama tokiga bog’liqligi bo’lgan to’g’rilagichning tashqi tafsifi;
ventillarni tanlash uchun Utes teskari kuchlanish,
To’g’rilash sxemalardagi transformatorlar uchun quyidagi parametrlar aniqlanadi:
ikkilamchi cho’lg’am kuchlanishi U2 va toki I2, chunki ularni to’g’rilangan kuchlanish va tokning o’rtacha qiymati (o’zgarmas tashkil etuvchi) bilan taqqoslash qabul qilingan;.
birlamchi cho’lg’am kuchlanishning U1 va tokining I1 ta’sir etuvchi qiymatlari;
ikkilamchi cho’lg’amning to’la quvvati S2;.
birlamchi cho’lg’amning to’la quvvati S1;
transformatorning to’la (gabarit) quvvati Str= (S1S2)2;
transformator ikkilamchi cho’lg’amidan foydalanish koeffitsienti K2=PoS2, bu erda Po to’g’rilagichning quvvati;
transformator birlamchi cho’lg’amidan foydalanish koeffitsienti K1=PoS1;
transformatordan foydalanish koeffitsienti Ktr=PoStr.
Bu koeffitsientlar to’g’rilash sxemasiga bog’liq, chunki bir taktli to’g’rilashda transformatorda majburiy magnitlash hodisasi mavjud bo’lib, u transformatordan foydalanish koefitsientini keskin kamaytiradi.
Bu chiqish parametrlarini ko’rib chiqamiz. To’g’rilash sxemasi bo’yicha to’g’rilagichlar bir fazali va ko’p fazali, bitta yarim davrli (bir taktli) va ikkita yarim davrli (ikki taktli) bo’ladi. Shuning uchun to’g’rilash fazalari soni m transformator ikkilamchi cho’lg’ami fazalari soniga mos kelmasligi mumkin. Bu son m=pn munosabatdan aniqlanadi (bu erda n=1,2,3,4,,,6 va h. k-transformatorning ikkilamchi cho’lg’amlari soni, p=1 yoki 2 to’g’rilanadigan yarim davrlar soni). Bir taktli yoki ikki taktli sxemalarni aniqlash shundan kelib chiqadiki, ta’minot kuchlanishni bir davrida transformator ikkilamchi zanjiri faza cho’lg’amidan nechta tok impulslar oqib o’tadi. Bir taktli to’g’rilagichda bir davrda bir fazali cho’lg’am orqali bitta tok impulsi, ikki taktli to’g’rilagichda esa ikki fazali cho’lg’am orqali ikkita tok impulsi oqib o’tadi. Shunday qilib, to’g’rilangan tok pulsatsiyasi chastotasi ta’minot tarmog’i chastotasiga mos tushmaydi va u ft.k.p=mftar bo’ladi.

Bog'liq Bir fazali toʻgʻrilagich qurilmalariBir kanalli to’g’rilagichning tuzilish sxemasi
Ventillar bir tamonlama o’tkazuvchanlikka ega va o’zgaruvchan tokni o’zgarmas tokka o’zgartirishni amalga oshiradi. To’g’rilagichda ularning soni to’g’rilash sxemasiga bog’liq bo’ladi. To’g’rilagichning har bir fazasi kamida bitta ventil zvenosiga ega bo’ladi. Lekin ko’p hollarda talab qilinadigan tok va kuchlanish qiymatini olish uchun har bir ventil zvenosida bir necha ventillar bo’lishi mumkin. Ventillar ketma-ket, parallel va murakkab guruhlarda ulanishi mumkin.
To’g’rilagichdan keyin kuchlanish yoki tok pulslanuvchan bo’ladi. Uni o’zgarmas va o’zgaruvchan tashkil etuvchilardan iborat deb tasavvur qilish mumkin. Telekommunikatsiya apparaturalari pulslanuvchan o’zgarmas tok bilan ta’minlanganda aloqa signallarini uzatishda jiddiy halaqitlar yuzaga kelishi mumkin. Bunga ruxsat etilmaydi va pulsatsiyani kamaytirish choralari ko’riladi. Buning uchun ventillar va ta’minlanadigan apparaturalar orasiga silliqlovchi filtr qo’yiladi. To’g’rilagichning chiqish kuchlanishi 10...15 foizga o’zgarishi mumkin bo’lgan ta’minot o’zgaruvchan kuchlanish qiymatiga bog’liq. Telekommunikatsiya apparaturalarida ko’pincha bunday sezilarli tebranishga ruxsat berilmaydi. Shuning uchun zamonaviy to’g’rilagichlarda filtrdan keyin tok va kuchlanish stabilizatorlari qo’yiladi. Bu zvenodan tashqari to’g’rilash qurilmasida kommutatsiyalash apparaturasi, himoyalash zanjiri va boshqalar bo’lishi mumkin.
To’g’rilagichlar boshqariladigan va boshqarilmaydigan bo’ladi. Boshqarilmaydigan to’g’rilagich chiqish kuchlanishini boshqarish imkoniyatini bermaydi. U hamisha U0=K·U2 munosabat orqali aniqlanadi ( bu erda U0– chiqishdagi o’zgarmas tok kuchlanishi, U2–to’g’rilagich kirishidagi o’zgaruvchan tok kuchlanishi, K–to’g’rilash sxemasining doimiy koeffitsienti).
Agar bunday to’g’rilagichda chiqish kuchlanishini o’zgartirish kerak bo’lsa, kirishdagi kuchlanishni o’zgartirishga to’g’ri keladi. Boshqariladigan to’g’ri–lagichlarda yuklamadagi o’zgarmas tok kuchlanishini to’g’rilagich ishlashi jarayonida to’g’rilagich ish rejimiga ta’sir qilgan holda o’zgartirish mumkin.
To’g’rilash qurilmasini quyidagicha sinflarga ajratish mumkin:
to’g’rilash sxemasi bo’yichabir fazali va ko’p fazali, bitta yarim davrli (bir taktli) va ikkita yarim davrli (ikki taktli );
quvvat bo’yichakichik quvvatli (100 Vt gacha), o’rta quvvatli (5 kVt gacha), katta quvvatli (5 kVt dan yuqori);
to’g’rilangan tok chastotasi bo’yichasanoat chastotasi (50Gts), oshirilgan chastotali (400 yoki 1000Gts), yuqori chastotali (1000Gts dan yuqori);
kuchlanish bo’yichakichik kuchlanishli (250 V gacha), o’rta kuchlanishli (1000 V gacha), yuqori kuchlanishli (1000 V dan yuqori);
ish yuklamasining rejimi bo’yichauzoq vaqtli, impulsli, qisqa vaqtli;
to’g’rilagichga yuklamaning reaktsiyasi bo’yichaaktiv, induktiv va sig’im reaktsiyali.

Geographical position and notice area limits in relation to ships position are easily identified.
Information expands when clicking the notice area.
|
You still need to look at devise not integrated in the bridge equipment.
Or, if integrated, in i.e. ECDIS, when displaying the notice area other vital chart information might get cluttered.
|
The area notice would benefit from more integration.
But doing so graphic overload in i.e an ENC is a risk.
Integrating with existing ENC symbology is desired.
Use semi-transparent text box.

Bog'liq DigitalEvidenceAre there any misconceptions or anything else about digital evidence that might be important to the non-scientist?
There are a number of common misperceptions about the retrieval and usefulness of digital evidence, including:
Anything on a hard drive or other electronic media can always be retrieved. This is incorrect as over-‐written or damaged files, or physical damage to the media can render it unreadable. Highly specialized laboratories with clean rooms may be able to examine hard drive components and reconstruct data, but this process is very laborious and extremely expensive.
Decrypting a password is quick and easy, with the right software. With the increasing complexity of passwords including capitals, numbers, symbols and password length, there are billions of potential passwords. Decryption can take a great deal of time, up to a year in some cases, using
system resources and holding up investigations. Gathering passwords from those involved in a case is much more efficient and should be done whenever possible.
Any digital image can be refined to high definition quality. Images can be very useful for investigations, but a low resolution image is made by capturing fewer bits of data (pixels) than higher resolution photos. Pixels that are not there in the first place cannot be refined.
Investigators can look at digital evidence at the crime scene or any
time. Just looking at a file list does not damage the evidence. It is crucial to note that opening, viewing or clicking on files can severely damage forensic information because it can change the last access date of a file or a piece of hardware. This changes the profile and can be considered tampering with evidence or even render it completely inadmissible. Only investigators with the proper tools and training should be viewing and retrieving evidence.
First responder training lags behind advancements in electronics.
Without regular updates to their training, responders may not be aware of what new digital devices might be in use and subject to collection. For example, there should be an awareness that thumb drives and SD cards can be easily removed and discarded by a suspect in the course of an encounter with law enforcement.

User tests with captains and pilots have been done in the full mission bridge simulator at Chalmers University of Technology, Sweden.
|
Tests showed showing positive results and the users gave positive comments. However some commented that intended route negotiations should not be used in COLREG situations.
|
An interesting new behavior was detected during those simulations. Without having been told so, the OOWs started to move waypoints ahead of their position to “negotiate” a clear passage as soon as they realized that they were on a collision course with the other vessel. This new behavior needs to be investigated in depth to find out if it poses any threat to safety.

Bog'liq DigitalEvidence Common Terms
Common terminology is critical in the digital evidence world. The Scientific
Working Group on Digital Evidence (SWGDE) in collaboration with the
Scientific Working Group on Imaging Technology (SWGIT) has developed and continuously maintains a glossary of terms used within the digital and multimedia disciplines. SWGDE has used ASTM International, a recognized standards organization, to establish international acceptance of terminology.
SWGDE/SWGIT’s full glossary is available online:
(http://www.swgde.org/documents/current-‐documents/SWGDE SWGIT Combined Glossary V2.5.pdf)
Some common terms include:
Cloud Computing -‐ software, applications and digital storage that is accessed on the Internet through a web browser or desktop or mobile app. The software and user's data are stored on servers at a remote location.
Data -‐ Information in analog or digital form that can be transmitted or processed. Data Extraction -‐ A process that identifies and recovers information that may not be immediately apparent.
Encryption -‐ procedure that converts plain text into symbols to prevent anyone but the intended recipient from understanding the message.
File Format -‐ The structure by which data is organized in a file.
Forensic Wipe -‐ A verifiable procedure for sanitizing a defined area of digital media by overwriting each byte with a known value; this process prevents cross-‐contamination of data.
Handheld (Mobile) Devices -‐ Handheld devices are portable data storage devices that provide communications, digital photography, navigation systems, entertainment, data storage, and personal information management.
Hash or Hash Value -‐ Numerical values that represent a string of text (search term), generated by hashing functions (algorithms). Hash values are used to query large sums of data such as databases or hard drives for specific terms. In forensics, hash values are also used to substantiate the integrity of digital evidence and/or for inclusion and exclusion comparisons against known value sets.

Bog'liq DigitalEvidenceWhat information does the report include and how are the results interpreted?
Like other forms of evidence, digital evidence must remain pristine and unaltered. In a courtroom, text messages would most likely be shared on the
actual phone or digital device, but other evidence might be printed out, such as a string of emails or email headers.
Sample email header showing the path and timing of the message.
This can show a track record of information exchange, and the “hash value”, also referred to as a checksum, hash code or hashes, is the mark of authenticity and must be present and explained to courtroom participants.
Hash values calculated for the text string “forensic science”. Each line contains the search term value calculated using the unique algorithm in the left hand column.
A hash value is the result of a calculation (hash algorithm) performed on a string of text, electronic file or entire hard drive contents. Hash values are used to identify and filter duplicate files (i.e. email, attachments, and loose files) from a given source and verify that a forensic image or clone was captured successfully. For example, a hash function performed on a suspect’s hard drive should generate a hash value report that exactly match the report generated by using the same algorithm on the hard drive’s image, typically created by the laboratory for use in the investigation. Hash values are a reliable, fast, and a secure way to compare the contents of individual files and media. Whether it is a single text file containing a phone number or five terabytes of data on a server, calculating hash values is an invaluable process for evidence verification in electronic discovery and computer forensics.
Once verified, the information pulled from the files can be shown in the courtroom, such as photos or emails. In addition, email headers, showing the path and timing emails took to get from source to destination could be displayed.

The interviewed bridge crew of Frej was very positive. The satellite image updated every day is intensively studied. Changes due to wind drift of the ice are studied, openings, and ridges are visible.
|
Even if the system allows overlay of some geographical features like the coastline, or the 10 m depth couture, it is not an ECDIS and integration with other types of chart information is not possible.

Maritime Data Collection System
|
The Maritime Data Collection System (MDCS) is a web‐based system that allows coastal agencies and hydrographic agencies of countries within the BLAST project to gather new information for use in nautical publications and charts for the North Sea.
Charts and sailing directions are still manually updated based on observation reaching the different hydrographic and coastal administrations from mariners and other reporters. These reports are delivered by radio, telephone or email.
|
In every country there may be several authorities that have the responsibility of updating nautical publications of different kinds. Often it can be difficult for the mariner to know to whom he should report a detected discrepancy.
MDCS will allow members of the public, or professionals like pilots, fishermen and seafarers to enter information through a generic web interface in the whole of the North Sea Region and the information will automatically be routed to the proper authority.

Bog'liq 5-maruza OTturlari (1)Ko’pprotsessorli ishlov berish Ko'pprotsessorli kompyuterlarning operatsion tizimlari qo'shimcha ravishda quyidagilarni ta'minlashi kerak: - barcha protsessorlar ish bilan band bo’lishi;
- tizimda jarayonlarning bir tekis taqsimlanganligi;
- o'zaro bog'liq jarayonlarning bajarilishining sinxronlashtirilishi;
- jarayonlar umumiy xotirada saqlanadigan ma'lumotlarning izchil nusxalari bilan ishlaydi;
- tupik holatdagi vaziyatdan chiqish uchun istisno holati taqdim etilishi.
Ko'p shoxchali qo'llab-quvvatlash - Ko'p shoxchali qo'llab-quvvatlash. Operatsion tizimlarning muhim xususiyatlaridan biri – bu bitta vazifa doirasida hisob-kitoblarni parallellashtirish qobiliyatidir. Masalalalarni ko'p shoxchalarga bo’lishda OT protsessor vaqtini masalalar o'rtasida emas, balki ularning alohida shoxchalari (iplari) o'rtasida taqsimlaydi.
Ko’pdarajali tizimlar - OTni ular o'rtasida aniq belgilangan munosabatlarga ega bo'lgan darajalar ierarxiyasi sifatida tashkil etiladi. Unda N darajadagi ob'ektlar faqat N-1 darajadagi ob'ektlarni chaqira oladi. Bunday tizimlarda pastki daraja odatda apparat, yuqori daraja esa foydalanuvchi interfeysi hisoblanadi. Daraja qanchalik past bo'lsa, ushbu darajadagi modul shunchalik imtiyozli buyruqlar va amallarni bajarishi mumkin.
- Darajalar OT funktsiyalari guruhlari tomonidan shakllanadi - fayl tizimi, jarayon va qurilmalarni boshqarish va boshqalar. Har bir qatlam faqat o'zining bevosita qo'shnisi bilan o'zaro muloqat qilishi mumkin. Amaliy dasturlar yoki OT modullari so'rovlarni ushbu qatlamlarga yuqoriga va pastga o'tkaza oladi.
- Ushbu yondashuv birinchi marta 1968 yilda Deykstra va uning talabalari tomonidan THE (Technishe Hogeschool Eindhoven) tizimini yaratishda qo'llanilgan.
Ko’pdarajali tizimlar Meynfreymlar operatsion tizimlari - Mainframe (mainframe) – bu muhim kiritish-chiqarish resurslariga, katta hajmdagi operativ xotiraga va tashqi xotiraga ega boʻlgan, intensiv paketlar va operativ tranzaksiyaga ega boʻlgan muhim tizimlarda foydalanish uchun moʻljallangan yirik universal yuqori unumdorli serverdir.

Solaris, tekin, yadrosi: Unix 6. Free BSD, tekin, yadrosi: Unix 7. Chrome OS, tekin, yadrosi: Linux 8. CentOS, tekin, yadrosi: Linux 9. Debian, tekin, yadrosi: Linux yoki Hurd. 10. Deepin, tekin, yadrosi: Linux - Virtual mashina - bu maxsus dasturlar (VirtualBox, VMware, Hyper-V) yordamida sun'iy ravishda yaratilgan virtual kompyuterdir. Virtual kompyuter o'zining operativ xotirasi, qattiq diski va protsessoriga ega bo’ladi. U ornatilgan kompyuterning ba'zi resurslaridan (RAM, protsessor va qattiq disk) foydalanadigan ichki kompyuter hisoblanadi.
- Virtual operatsion tizim – bu virtual mashinaga o'rnatilgan OTdir. Siz virtual mashinaga kompyuteringizga o'rnatishingiz mumkin bo'lgan va virtualizatsiya uchun ishlatiladigan dasturiy ta'minot tomonidan qo'llab-quvvatlanadigan har qanday OTni o'rnatishingiz mumkin. VirtualBox, VMware kabi vurtuallashtiruvchi dasturlar Windows, Linux, macOS, FreeBSD OTlarni o’rnatish imkonini beradi.
Virtual operatsion tizim - Virtual OTni o’rnatishning 3 sababi:
2. Whonix Otni o’rnatish; 3. bir nechta OT bilan ishlashni o’rganish. Whonix – virtual operatsion tizimi - Whonix - bu anonim va xavfsizlik qaratilgan Linuxga asoslangan operatsion tizim. U foydalanuvchining IP manzilini/joylashuvini yashirish uchun mo'ljallangan va ma'lumotlar trafigini anonimlashtirish uchun Tor tarmog'idan foydalanadi.
- Bu shuni anglatadiki, kirish serveri va Tor tarmog'i operatorlari qaysi saytlarga tashrif buyurilayotganini yoki foydalanuvchining jismoniy joylashuvini osongina aniqlay olmaydi.
