Shielded Metal Arc Welding (SMAW), also known as stick welding or manual metal arc welding (MMA), is a popular welding process that uses a consumable electrode coated with a flux to create a weld. Here’s an overview of the SMAW process: 1. Equipment: Welding Power Source: SMAW machines typically use either AC (alternating current) or… Continue reading Shielded Metal Arc Welding (SMAW)

Creating a White Window Using OpenCV
In computer vision and image processing applications, OpenCV (Open Source Computer Vision Library) is a widely used library for real-time computer vision. It provides a wide range of functions for image processing, manipulation, and analysis. Objective The objective of this program is to demonstrate how to create a window with a white background using OpenCV.… Continue reading Creating a White Window Using OpenCV
LoRaWAN – Rules and regulations
ISM Band LoRa operates in the unlicensed ISM (Industrial, Scientific and Medical) radio band that is available worldwide. In India, LoRaWAN operates in the 865-868 MHz frequency band. Devices such as microwave ovens, medical equipments or baby monitors all uses the ISM band ISM band advantages: Anyone can use these frequencies. No license… Continue reading LoRaWAN – Rules and regulations
UNDER CUTTING IN GEAR
In gear manufacturing, undercutting refers to the removal of material from the base of the gear tooth. This results in a groove or recess at the bottom of the tooth, giving it a concave shape. Undercutting is typically done to prevent interference between adjacent teeth, especially in gears with small numbers of teeth or high-pressure… Continue reading UNDER CUTTING IN GEAR
Creating Larger Arrays Using np.zeros() Function in NumPy
When working with NumPy, creating arrays of specific sizes filled with zeros is a common task, especially when initializing arrays for later use. While np.array() can be used to create arrays filled with zeros, an alternative method is to utilize the np.zeros() function provided by the NumPy library. The np.zeros() Function The np.zeros() function creates… Continue reading Creating Larger Arrays Using np.zeros() Function in NumPy
LoRaWAN Network and Components.
LoRa LoRa is an acronym for Long Range, and it is a wireless technology where a low powered sender transmits small data packages (0.3 kbps to 5.5 kbps) to a receiver over a long distance. LoRa is a physical proprietary radio communication technique. It is based on spread spectrum modulation techniques derived from chirp spread… Continue reading LoRaWAN Network and Components.
Low Power Wide area network
LPWAN stands for Low Power Wide Area Network and this type of wireless communication is designed for sending small data packages over long distances, operating on a battery. There are several competing technologies in the LPWAN space such as Narrowband IoT (NB-IoT), Sigfox, LoRa and others. LPWAN is not a single technology, but a group… Continue reading Low Power Wide area network
Modification of array using NumPy
We have the flexibility to modify individual elements within an array without altering the entire array.. Result: Explanation: import numpy as np: This line imports the NumPy library under the alias np. frame = np.array([[0,0,0],[0,0,0],[0,0,0]]): This line creates a 3×3 NumPy array filled with zeros, just like before. frame is initialized as a 3×3 array… Continue reading Modification of array using NumPy

Representation of arrays using NumPy
A simple array can be represented by using NumPy: Result: Explanation: import numpy as np: This line imports the NumPy library and gives it the alias np. This is a common convention to make it easier to refer to NumPy functions and classes in the code. frame = np.array([[0,0,0],[0,0,0],[0,0,0]]): This line creates a 3×3 NumPy… Continue reading Representation of arrays using NumPy
