    Activation Key .NET Class Library

    Activation Key .NET Class Library

    Represents the activation key used to protect your C# application.

    A specific software-based key for a computer program C# source code. It certifies that the copy of the program is original. It is also called a license key, product key, product activation, software key and even a serial number. The key can be stored as a human readable text for easy transfering to the end user. Contains methods for generating the cryptography key based on the specified hardware and software binding. An additional feature is the ability to embed any information directly into the key. This information can be recovered as a byte array during key verifying.

    PANDA

    PANDA

    A comprehensive and flexible quantification tool for proteomics data

    PANDA is a comprehensive and flexib tool for quantitative proteomics data analysis, which is developed based on our solid foundations in quantitative proteomics for years. Several novelties have been implemented in it. First, we implement the advantage algorithms of LFQuant (Proteomics 2012, 12, (23-24), 3475-84) and SILVER (Bioinformatics 2014, 30, (4), 586-7) into PANDA. Second, we consider the state-of-art concept of quantification reliability in this quantitative workflow. On the levels of spectra, peptides and proteins, PANDA works out a few quantitative filters and new scores for quantification confidence. Third, PANDA is designed for processing proteomics big data in parallel.

    Pack-Print-Cut

    Packing two dimensional rectangular elements at orthogonal table

    Program was created for optimized packing of two dimensional rectangular elements at orthogonal table with main purpose of printing cutting sheets that can be used for cutting material at production in wood and panel furniture manufacturing. It is developed upon authors several years of experience at woodworking, and actual carpenters needs when such software is in question. In spite its look it is fully functional peace of software , with all necessary elements needed for generating cutting sheets. GUI is simple and it consists of fields for entering table and element dimensions on the right. Packing, optimization, cutting and cleaning table edges section bottom left and statistic section bottom right. Upper left are table description field and cut sheet drawing at the center. Right click at the cut sheet drawing and there are printing options. NOTICE : This program was not created for sellers of chipboard and other board materials. All the best, Author

    Gemi

    Gemi

    PCR primers / probes design from multiple & degenerate sequences

    Gemi, an automated, fast, and easy-to-use bioinformatics tool with a user-friendly interface to design primers and probes for polymerase chain reaction (PCR). Gemi accepts multiple aligned and long DNA and RNA sequences with degenerate nucleotide (non-A/C/G/T bases). Gemi can be used for quantitative, real-time and conventional PCR (qPCR, rt-PCR, etc.), and Sanger sequencing. Gemi can parse large dataset of sequences efficiently. Python source code is available upon request. Milestone: The tool reached about 3000 downloads sine 2012. Article Gemi: PCR primers prediction from multiple alignments.

    OSM Explorer

    OSM Explorer

    Basic routing and spatial functions using OpenStreetMap data

    A mapping application for OpenStreetMap that renders OSM or MapQuest tiles and does basic routing from a built-in database. The main focus of this project is the development of a high-performance routing engine that can handle a variety of routing and vehicle constraints on demand without additional pre-processing of the road network. An additional goal is the development of a class library centered around a built-in, object-oriented database used for processing and storing OSM map data such that external dependencies (e.g. external database servers) are minimized.

    To give users the full control over the running application. This means that an application is working according to its purpose but the control over the whole interface is taken from developer and given to users. While an application is running, users can move, resize, and tune all the screen objects through which the communication with an application is going. Set of files includes the book (both in DOC and PDF formats), a big demonstration project with all its files available (all the source files are in C#), and an additional description of many used classes. Book uses the examples from the demo project to explain everything in details. The examples are from many different areas. Examples from the first part of the book are aimed at the details of algorithm and its use with different objects; examples from the second part are mostly the real and very useful applications.
