    It offers a user-friendly graphical user interface, which streamlines making HTML requests to test an APIs functionality without the hassle of writing a bunch of code. Because of this, it is an essential tool for the Internet of Things IoT projects. It is common to employ various APIs or even build one for the connection between IoT devices and web applications.

    For example, the pipelines for getting the status of devices and servers as well as sending messages and notifications to PCs and phones. You can use the Postman to test what data are sent to or received from the APIs.

    The Disqus comments can be an interesting data source for trend statistics and natural language analysis. You can build an application to consume and digest the information by getting the data from the API. With the Postman, you can quickly test the API endpoints and your parameters and then generate the codes for your prototype app.

    This article contains two beginner-level exercises. The first one is to get the discussion threads of a specific Disqus forum. The second one is to try querying the thread details by a thread ID, an identifier, or a source URL, respectively.

    Click on the Register new application button. In the registration form, fill in the name and description of your application as well as your organization and website. After that, you can find the API key for your registered application in its Details page.

    I suggest you start with a new workspace. In this way, you can isolate your projects and prevent override variables when you are unfamiliar with Postman. You can create unlimited Personal workspaces. To create a new workspace , select the workspace dropdown menu at the top and center of Postman, and click on Create New. Enter the name, such as Disqus API, for you to identify your workspaces. You can prevent accidentally share your values by making use of environments to store the values as environment variables.

    It does not require authentication. Both endpoints return the data in the same structure.

    Tubings are screwed together through connections, which could either be: By means of integral joint the most common type of connection on small diameter pipe , Or by using a coupling the most common connection ; a collar with internal threads used to join two sections of threaded pipe. Selection of tubing connections: The type of tubing connections selected for a completion will depend mainly on the well characteristics.

    The connection must be able to contain the produced fluids safely and at the maximum pressures anticipated. The basic requirements of a tubing string connection are: Strength compatible with the operational requirements of the string during, and after running; Sealing properties suitable for the fluid and pressures expected; Ease of stabbing during make-up, and safe breakout when pulling the tubing; Resistance to damage, corrosion, and erosion. API threads have a taper of 6.

    They are triangular and rounded on top. The seal is made by grease trapped between the threads, which is sufficient for low-pressure oil wells. API connections are perfectly well adapted and sufficient for most oil wells. Premium connections: Premium connections are proprietary connections that offer premium features not available on API connections.

    Most offer a metal-to-metal seal e. VAM joint and Hydril joint for improved high pressure seal integrity. Premium connections exist with features such as flush connections, recess free bores, and special clearance.

    This type of connection is preferred for gas wells, high-pressure wells, as well as for wells producing corrosive effluents. An example of a premium thread is shown in the following Figure. References: Well Completion and Servicing, D. Perrin Editions Technip.

    Special clearance coupling When specified in the order, special-clearance reduced outside diameter couplings for buttress casing and external upset tubing shall be furnished. Combination coupling Reducing coupling are used to connect two pipes of different diameter with the same or different types of thread on the two ends, and shall be furnished when specified on the agreements.

    The minimum length and minimum diameter of reducing couplings shall be sufficient to accommodate the specified size and type of threads.

    Differences between Casing coupling and tubing coupling There are couplings for casing and couplings for tubing, the function is the same that to connect the pipe each other.

    On the other hand, still there are some differences between the two. Because of the end of the tubing is thickened upsetthe connecting stress is better than buttress coupling. Features The oil tubing coupling can solve the problem of fatigue fracture in the existing coupling due to stress concentration. Oil tubing end is connected to the inside wall of the coupling in a tapered thread.

    The coupling body end and oil tubing are connected with same thread pitch flat thread. The coupling is not easy to produce fatigue fracture, and has good connection effect. It can prevent the accident of oil well pipe string break effectively.

    The oil casing coupling is a necessary piece used to connect the two casing. The coupling manufacturing method is the same as seamless pipe. The steel pipe ends with internal thread to connect with the upper and lower casing.

    In order to ensure the joint tightness, the precision of screw thread is strictly required. Couplings shall not be expanded to provide required threads taper under API specifications.

    NOTE Couplings with API threads may not have a leak resistance as high as the internal yield pressure of the pipe body, due to inadequate bearing pressure between the coupling and pin. Threading and Gauging API 5B covers dimensions, tolerances, and marking for API threads and the gauges that control the acceptance criteria for the threads.

    It includes thread element gauges, instruments, and requirements for the inspection of threads for line pipe, casing and tubing round threadsand buttress casing connections.

    However, a separate QThreadPool can be created and managed explicitly. Qt Concurrent: Using a High-level API The Qt Concurrent module provides high-level functions that deal with some common parallel computation patterns: map, filter, and reduce.

    Unlike using QThread and QRunnablethese functions never require the use of low-level threading primitives such as mutexes or semaphores. Instead, they return a QFuture object which can be used to retrieve the functions' results when they are ready.

    Qt Concurrent 's map, filter and reduce algorithms automatically distribute computation across all available processor cores, so applications written today will continue to scale when deployed later on a system with more cores. This module also provides the QtConcurrent::run function, which can run any function in another thread. However, QtConcurrent::run only supports a subset of features available to the map, filter and reduce functions. The QFuture can be used to retrieve the function's return value and to check if the thread is running.

    See the Qt Concurrent module documentation for details on the individual functions. Each WorkerScript instance can have one.

    1. I think, that you are not right. I am assured. I can defend the position. Write to me in PM, we will discuss.
