Audio steganography My graduate work is to make research into part of information security which is called information hiding. I use echo signals for embedding digital watermark into audio signal. It might be any music, songs , speech and so forth. For example, we can use two echo signals with different delay.People's ears can't recognise echo when delay is very short. But there are two contradictory factors. The more amplitude echo is, the better for our system, becouse extracting is mor easily. On the other hand, large amplitude affects sound quolity. For instance, when amplitude is too big, it's possible to hear some sizzle and other distoration of music. There are many contradictoring factors, and one of my purposes is to find balance between them. In conclusion, let me say that there is much work to do in this area,and I hope I will have done at least small part of it when I end my university.

Moon and Sixpence by Somerset Moughm I'd like to write here about a book I read a few weeks ago. In the first chapters we can see a man and his wife. The man was called Strikland. He was forty.He had an excellent wife, two nice children. He had a very good job. They lived in luxury and comfort. Strikland was very ordinary man. He loved his wife and his cildren. He had lived about twenty years that way. He was very far from art. He had not got any hobbies. But he was kind and thoughtful. His wife liked arts. She often have some guests - painters, writers and so forth. One day Strikland dissapeared. He left his family without any money. Everyone thought that he left his wife for a woman. No one could think that he did it for art. He became a painter.He became very selfish person. He lived in terrible room which was very cheap. He left his work and family for art. People did not liked his pictures. They said that he was self important, egoistic without any talent. But he was genius. People understood it only after his death. Some people who bought his pictures for very little money , sold them for vast sum of money. What is better? First part of his life or second? Do you think better be just usual man, but hav someone who loves you or be genious, but egoistic and alone?

Question about verbs There are two sentences the first — Mości pułkowniku — rzekł — nieraz po to jeno ojciec dziecko przygani, by ktoś jego słowom zaprzeczył, i tak mniemam, że nie można rodzicielskiego serca bardziej udelektować, jak przyganie negując and the second Przyznaję, że gdybym go był wówczas złapał, byłbym mu był pro memoria nie żałował, ale teraz trzeba będzie, widzę, zaniechać, bo mi się znowu na jakie dziesięć lat pochowa, a staremu tęskno. There are two verbs 1) mniemam 2) przyznaję, It seems, that there first person (I ) in both, both are singular, the time is present in both więc, why there are different endings ( -am and -ę ) ?

Лукоморье. Александр Сергеевич Пушкин У лукоморья дуб зелёный; Златая цепь на дубе том: И днём и ночью кот учёный Всё ходит по цепи кругом; Идёт направо - песнь заводит, Налево - сказку говорит. Там чудеса: там леший бродит, Русалка на ветвях сидит; Там на неведомых дорожках Следы невиданных зверей; Избушка там на курьих ножках Стоит без окон, без дверей; Там лес и дол видений полны; Там о заре прихлынут волны На брег песчаный и пустой, И тридцать витязей прекрасных Чредой из вод выходят ясных, И с ними дядька их морской; Там королевич мимоходом Пленяет грозного царя; Там в облаках перед народом Через леса, через моря Колдун несёт богатыря; В темнице там царевна тужит, А бурый волк ей верно служит; Там ступа с Бабою Ягой Идёт, бредёт сама собой, Там царь Кащей над златом чахнет; Там русский дух... там Русью пахнет! И там я был, и мёд я пил; У моря видел дуб зелёный; Под ним сидел, и кот учёный Свои мне сказки говорил.
