Q8Cis Apps is an Engineering applications for : - 1D Hydrodynamic's Prediction for Arabian Gulf waters [based on KGulf model {Al-Salem 2009}] Tidal range and the speed of the current can affect Shipping - entering/leaving harbours, coastal areas Information for study effect of sediment/pollutant transport. Coastal fishing This Apps allows user to setup a station in Arabian Gulf waters for Hydrodynamic's Prediction at selected [Longitude/Latitude]. Based on the amplitude and phase a harmonic constituents (22 constituents) will be predicted and used. Also it can be recall at any time from stored file in Directory for more prediction. Time limit for water hydrodynamic prediction can be from 1979 to 2035. Hourly Display. - Global Water Level Prediction [based on KTide model {Al-Salem 2004} ] Prediction of tidal variations is of importance in a wide range of practical applications such as: Navigation through inter-coastal waterways, and within estuaries, bays, harbors and fishing. The information provided by this apps can be further used as input for tidal circulation models. Q8Cis apps is capable to predict water level variation due to tides at a number of stations [1325 stations] in the Global waters. The apps will display for user a number of Continents Icon to select a station as follow: Asia Region Africa Region Europe Region North America Region South America Region 
 Time limit can be select from 1979 to 2035. Hourly Display.

About

Reader IQ

That Spanish you took in high school, the language your abuela still speaks at home, the manga you've always wanted to read in the original β€” Reader IQ gets you there. Hard words are translated right above the line, a tap on any word explains it in context, and every book can be listened to as well as read. BOOKS THAT SPEAK. AUDIOBOOKS YOU CAN READ. Focus mode turns any book into a listening lesson β€” no audio edition needed. It reads any e-book aloud sentence by sentence and highlights each word as it's spoken. For supported language pairs on compatible devices, it shows full-sentence subtitles; otherwise, word translations remain available. Tap any word for the dictionary without stopping the audio. On compatible devices and systems, where the book's language and speech model are supported, on-device transcription turns audiobook speech into word-synced text with translated subtitles; otherwise, the audiobook still plays normally. Listening time counts toward shared time, streak, and goal totals. YOUR BOOKS, MANY FORMATS Tired of a library that runs out of new stories after a few weeks? Import your own β€” from email, cloud, messaging apps, or your browser β€” and the catalog never runs dry: - Books: EPUB, FB2, MOBI, AZW3, TXT, Markdown and more - Research & scans: PDF and DjVu β€” scanned pages read with on-device OCR - Comics: CBZ, including manga read right to left, the way it was drawn - Audiobooks: m4b, mp3 and more TRANSLATIONS ABOVE THE LINE β€” ONLY WHERE YOU NEED THEM Brushing up before a trip to Mexico City, or starting Japanese from scratch? Tell Reader IQ your level β€” or take a two-minute test β€” and it translates only the words you don't know yet, right above the line. You read for meaning, not decoding, and the hints fade as your vocabulary grows. A DICTIONARY THAT UNDERSTANDS CONTEXT Tap any word and an on-device model reads the sentence to select the most likely meaning β€” "spring" the season, not the coil. Pronunciation, word forms, example sentences, conjugation tables for 8 languages, and kanji/hanzi breakdowns with stroke order. Once downloaded, the dictionaries live on your device and work offline. A GRADED PATH FROM YOUR FIRST 10 WORDS You don't start with a 400-page novel. Adapted books and a graded path of short stories take you from your first words to longer texts, adding just a few new words at each step. Read-along speech, quizzes and spaced re-reads make it stick β€” so you're ready when you pick up a real novel. SPACED REPETITION, STRAIGHT FROM YOUR BOOKS Every word you tap is saved with the sentence it came from, and that sentence becomes your flashcard. Four practice modes β€” recognition, fill-in-the-blank from your own books, listening, and typed recall β€” run on a real spaced-repetition schedule with honest next-review dates. Meet a saved word again while reading and it advances on its own: reading is the review. See how much of each level (A1–C2) you've covered, and export your words β€” handy for a book club reading the same title. GOALS, STREAKS AND 40 AWARD LADDERS Set a daily reading goal and keep it going with a weekly ring and a heatmap. Set a word-count goal for a date and watch it get closer. Around 40 awards celebrate how learning actually happens β€” first book finished, longest streak, biggest day, getting back on track after you fall off. 10 READING LANGUAGES English, Spanish, French, German, Italian, Japanese, Korean, Portuguese, Chinese, and Thai. Pinyin with tone colors, furigana and vertical Japanese text, Thai tone marks, and beginner modes if you don't know the script yet. Translations into 30+ languages. Reading in the original is still the most natural way to learn a language β€” no drills, just the story pulling you forward. Reader IQ clears out what made it hard: the dictionary detours, books too advanced, words forgotten the next day. Open your first book tonight.
