فرمانده سپاه ثارالله استان کرمان با اشاره به حمله تروریستی ۱۳ دی‌ماه سال گذشته در گلزار شهدا گفت: دشمنان ما گمان می‌کردند که با این‌گونه اقدامات کور می‌توانند مردم را از مکتب شهید سلیمانی جدا کنند، اما این تلاش‌ها بی‌ثمر بود. خون شهیدان و عشق مردم به مکتب حاج قاسم نشان داد که این راه ادامه دارد.

Types of SMS Message

There are four classes of an SMS message. Classes identify the importance of an SMS message and also the location where it must be stored.

Class 0

This type of SMS message is displayed on the mobile screen without being saved in the message store or on the SIM card; unless explicitly saved by the mobile user.

Class 1

This message is to be stored in the device memory or the SIM card (depending on memory availability).

To encode U+10437 to UTF-16:

• Subtract 0x10000 from the code point, leaving 0x0437.
• For the high surrogate, shift right by 10 (divide by 0x400), then add 0xD800, resulting in 0x0001 + 0xD800 = 0xD801.
• For the low surrogate, take the low 10 bits (remainder of dividing by 0x400), then add 0xDC00, resulting in 0x0037 + 0xDC00 = 0xDC37.

To decode U+10437  from UTF-16:

• Take the high surrogate (0xD801) and subtract 0xD800, then multiply by 0x400, resulting in 0x0001 × 0x400 = 0x0400.
• Take the low surrogate (0xDC37) and subtract 0xDC00, resulting in 0x37.
• Add these two results together (0x0437), and finally add 0x10000 to get the final code point, 0x10437.

برخی مقامات ارشد نظامی اسرائیل اکنون بر این باور هستند که به جای حمله به حوثی‌ها در یمن «اقدام مستقیم» علیه ایران باید در اولویت قرار گیرد.

نتایج طرح فروش خودرو در سامانه یکپارچه اعلام شد و طی آن شاهد هستیم که برای بسیاری از متقاضیان، خودرویی تخصیص نیافته است و بسیاری دیگر نیز باید خودروهای خود را در زمستان ۱۴۰۳ تحویل بگیرند که این مسئله با قول هایی که پیش از این برای تحویل فوری خودروها به مردم داده شده بود کاملاً متناقض است.

Address Example  : 

Alphanumeric address is at first put to the GSM 7-bit default alphabet, then encoded the same way as any message text in TP-UD field (that means it is 7-bit packed) and then the address is supplied with the "number" length and TON and NPI.

For example, a fictional alphanumeric address Design@Home is converted to the GSM 7-bit default alphabet which yields 11 bytes 44 65 73 69 67 6E 00 48 6F 6D 65 (hex), the 7-bit packing transforms it to 77 bits stored in 10 octets as C4 F2 3C 7D 76 03 90 EF 76 19; 77 bits is 20 nibbles (14 hex) which is the value of the first octet of the address. The second octet contains TON (5) and NPI (0), which yields D0 hex. The complete address in the GSM format is 14 D0 C4 F2 3C 7D 76 03 90 EF 76 19.
