Learn to build modern, secure, highly available web MVC applications and API’s using python`s Flask framework. Key Features • Create production-ready MVC and REST API with the dynamic features of Flask • Utilize the various extensions like Flask-JWT and Flask-SQLAlchemy to develop powerful applications • Deploy your flask application on real-world platforms like AWS and Heroku on VM’s or Docker containers Book Description Flask is a popular python framework known for its lightweight and modular design. Mastering Flask Web Development will take you on a complete tour of the Flask environment and teach you how to build a production-ready application. You'll begin by learning about the installation of Flask and basic concepts such as MVC and accessing a database using an ORM. You will learn how to structure your application so that it can scale to any size with the help of Flask Blueprints. You'll then learn how to use Jinja2 templates with a high level of expertise. You will also learn how to develop with SQL or NoSQL databases, and how to develop REST APIs and JWT authentication. Next, you'll move on to build role-based access security and authentication using LDAP, OAuth, OpenID, and database. Also learn how to create asynchronous tasks that can scale to any load using Celery and RabbitMQ or Redis. You will also be introduced to a wide range of Flask extensions to leverage technologies such as cache, localization, and debugging. You will learn how to build your own Flask extensions, how to write tests, and how to get test coverage reports. Finally, you will learn how to deploy your application on Heroku and AWS using various technologies, such as Docker, CloudFormation, and Elastic Beanstalk, and will also learn how to develop Jenkins pipelines to build, test, and deploy applications. What you will learn • Develop a Flask extension using best practices • Implement various authentication methods: LDAP, JWT, Database, OAuth, and OpenID • Learn how to develop ro

Natural/random protein classification models based on star network topological indices

JOURNAL OF THEORETICAL BIOLOGY 2008年第4期254卷 775-783页

The development of the complex network graphs permits us to describe any real system such as social, neural, computer or genetic networks by transforming real properties in topological indices (TIs). This work uses Randic's star networks in order to convert the protein primary structure data in specific topological indices that are used to construct a natural/random protein classification model. The set of natural proteins contains 1046 protein chains selected from the pre-compiled CulledPDB list from PISCES Dunbrack's Web Lab. This set is characterized by a protein homology of 20%, a structure resolution of 1.6 angstrom and R-factor lower than 25%. The set of random amino acid chains contains 1046 sequences which were generated by python script according to the same type of residues and average chain length found in the natural set. A new Sequence to Star Networks (S2SNet) wxpython GUI application (with a Graphviz graphics back-end) was designed by our group in order to transform any character sequence in the following star network topological indices: Shannon entropy of Markov matrices, trace of connectivity matrices, Harary number, Wiener index, Gutman index, Schultz index, Moreau-Broto indices, Balaban distance connectivity index, Kier-Hall connectivity indices and Randic connectivity index. The model was constructed with the General Discriminant Analysis methods from STATISTICA package and gave training/predicting set accuracies of 90.77% for the forward stepwise model type. In conclusion, this study extends for the first time the classical TIs to protein star network TIs by proposing a model that can predict if a protein/fragment of protein is natural or random using only the amino acid sequence data. This classification can be used in the studies of the protein functions by changing some fragments with random amino acid sequences or to detect the fake amino acid sequences or the errors in proteins. These results promote the use of the S2SNet application not o

13th Brazilian Symposium on Software Components, Architectures, and Reuse (SBCARS) / 10th Brazilian Conference on Software (CBSOFT)

If on one hand frameworks allow programmers to reuse well-known architectural solutions, on the other hand they can make programmers unaware of important design decisions that should be followed during software construction, maintenance and evolution. And if programmers are unaware of these design decisions, there is a high risk of introducing design violations in the source code, and the accumulation of these violations might hinder software maintain-ability and evolvability. The use of static analysis tools might be employed to mitigate these problems by assisting the detection of recurring design violations in a given architectural pattern. In this work, we present MTV-Checker, a tool to assist the automatic detection of 5 design violations in Django-based web applications. We also conducted an empirical study in the context of the SUAP system, a large-scale Django-based information system with more than 175.000 lines of python code currently deployed in more than 30 Brazilian institutions. Our results present the most recurrent violations, how they evolve along software evolution, and the opinions and experiences of software architects regarding these violations.

3D Visualization of geological structures using python: the case study of the Palomeque sheets (SE, Spain)

引用

JOURNAL OF MAPS 2023年第1期19卷

作者： Bullejos, Manuel Martin-Martin, Manuel Univ Granada Dept Algebra Granada Spain Univ Alicante Dept Ciencias Tierra & Medio Ambiente Alicante 03080 Spain

The goal of this paper is the construction of computerized 3D visualization of geological structures. Several python applications have been used to adapt the paper map-based geological classical information to numerical geological maps represented in HTML files. The models include a map with the stratigraphic and structural contacts and symbols, five serial vertical sections, and a geological block diagram, all with real topography. This block diagram made with 2D figures allows a 3D visualization. Palomeque area (Murcia region, southeastern Spain) has been used as a key-case. This area consists of a deformed Upper Cretaceous to Oligocene succession belonging to the Internal Zone Malaguide Complex. The main structure consists of two thrust-fold sheets forming an imbricate system, also affected by a set of strike-slip faults with a sinistral regime. The constructed maps show a good agreement with the published classical geological maps and cross-sections demonstrating the benefits of using these python applications.
