BigSIA

Read full description

The BigSIA is an application designed, developed and sold by Manuel Rodríguez Vallejo for teaching and research purposes. Provides information to the Anterior Segment Surgeon about Corneal Induced Astigmatism (SIA) during Cataract Surgery. The application provides information to allow the surgeon to make a clinical decision based on his or her own knowledge. How to use The BigSIA? 1.- INTRODUCE SUBJECTS The first step is to introduce a subject measured during the preoperative and postoperative follow-up. The preoperative and postoperative corneal powers are the main variables although other variables can be stored for later export and analysis by other software. The subject must be entered through a unique numeric Pseudoidentifier so that no personal data is stored in the device. It is the responsibility of the user to perform an appropriate Pseudoidentification procedure. 2.- CREATE EXAMS FOR SUBJECTS AND ASSIGN A PROTOCOL TO AN EXAM Once the Subject has been introduced, an Exam should be created in the Subject screen. After creating the first Exam it will be necessary to create a new Protocol that will be assigned to that Exam. A Protocol is a uniform way of acting in such a way that the subsequent analysis is reliable. For example, a protocol could include right eyes measured with a particular instrument with a 2.2 mm temporal incision. We can assign a protocol name "protocol1" and all the subjects whose right eyes have been operated on the same incision and measured with the same instrument can be assigned to the same "protocol1". Any variation must be recorded in a different protocol, for example, if I change the eye by the left eye, I must change the protocol and it can not be assigned to "protocol1". Once the Exam is created and assigned the Protocol to it, the preoperative and postoperative corneal power data are inserted. The App will calculate the SIA for that exam. Obviously, preoperative and postoperative astigmatism must be measured through the same device. 3.- ANALYZE THE DATA After having a series of patients undergoing surgery and measured under the same protocol, we can calculate a double-angle chart with the statistics of centrality and dispersion. What are the benefits of the PRO account? The App can be downloaded for free but only 30 subjects and 1 protocol can be included. Users with the PRO annual subscription can include an unlimited number of subjects, unlimited number of protocols, import and export of data in .CSV format, export of plots in vector format, making backup copies, filter according to the magnitude of the preoperative Corneal astigmatism or filter according to the type of preoperative astigmatism (with-the-rule, against-the-rule or oblique). INFORMATION ABOUT PRO SUBSCRIPTION The BigSIA is a freemium app. If you want to access to all the services you have to buy a PRO auto-subscription for 19.99€ (prices can vary between countries) for a period of 1 year. The payment will be charged to your iTunes Account at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. Account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal. Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase. Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable.

This app is aimed at complete beginners who have never programmed before, as well as existing programmers who want to increase their career options by learning Python. And Python is the number one language choice for machine learning, data science and artificial intelligence. To get those high paying jobs you need an expert knowledge of Python, and that’s what you will get from this app. By the end of the app you’ll be able to apply in confidence for Python programming jobs. And yes, this applies even if you have never programmed before. With the right skills which you will learn in this app, you can become employable and valuable in the eyes of future employers. This is the most comprehensive, yet straight-forward, app for the Python programming language on Udemy! Whether you have never programmed before, already know basic syntax, or want to learn about the advanced features of Python, this app is for you! In this app we will teach you Python 3. Learn how to use Python for real-world tasks, such as working with PDF Files, sending emails, reading Excel files, Scraping websites for informations, working with image files, and much more! This app will teach you Python in a practical manner, with every lecture comes a full coding screencast and a corresponding code notebook! Learn in whatever manner is best for you! We will start by helping you get Python installed on your computer, regardless of your operating system, whether its Linux, MacOS, or Windows, we've got you covered. We cover a wide variety of topics, including: Python Command Line Basics Installing Python Running Python Code Strings Python Python Lists Python Dictionaries Python Tuples Python Sets Python Number Data Types Python Print Formatting Python Functions Python Scope Python args/kwargs Python Built-in Functions Python Debugging and Error Handling Python Modules Python External Modules Python Object Oriented Programming Python Inheritance Python Polymorphism Python File I/O Python Advanced Methods Python Unit Tests and much more! What is this app about? The Python Mega app is an online app that uses a hands-on teaching approach which has proved to be very successful with thousands of students who have taken the app, built their own programs, and even found a Python job afterward. With 50,000+ student reviews and an outstanding 4.6 average rating, this learning package guarantees you will become a Python programmer after successful completion. The app focuses on teaching you Python by building real-world Python programs. That way, you learn the language syntax, but most importantly, you will learn the actual skill of designing and building real-life programs. I don’t know anything about programming. Will I still be able to learn Python? Yes. This app assumes you have no previous knowledge of programming. Whenever a new programming term emerges in the lectures, we will first explain it academically. Then we use it practically in a real-world code example and reuse it in exercises until you learn everything by heart. I know Python basics. Is this app for me? Yes. The first 12 sections of the app cover Python basics. The other 27 sections cover intermediate and advanced Python, and you can jump right into those sections if you know the basics. What does the content include? The app is designed around mastering Python by building ten applications that vary from simple to complex. The ten apps are carefully served to students through a combination of tutorials, coding exercises, quizzes, code notebooks, cheat sheets, and unlimited support from the instructor and the teaching assistant in the app forum. You will also receive an invitation to join our Discord server to chat with other fellow students, participate in code challenges, and get help when you need it to make sure you stay tuned and motivated.
