API testing validates application programming interfaces (APIs). API testing focuses on functionality, reliability, performance, and security of programming interfaces. Common protocols for API testing include HTTP, REST, SOAP, JMS, and UDDI. REST uses normal HTTP verbs like GET, POST, PUT, and DELETE and supports data formats like plain text, HTML, XML, and JSON. CRUD (create, read, update, delete) operations can be performed through HTTP requests in API testing.

Typically, when updating or developing an API like Newsdata.io which is a news API for a service to provide news data with quick response time, there are lengthy discussions about the API’s structure, naming, and functions. Although, over time, certain rules have emerged that can be applied to the process and aid in reaching a common ground while developing.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

2. What is API?
API (Application Programming Interface) is a computing interface
which enables communication and data exchange between two
separate software systems.
3. API Testing
API TESTING is a software testing type that validates Application
Programming Interfaces (APIs). The purpose of API Testing is to
the functionality, reliability, performance, and security of the
programming interfaces. In API Testing, instead of using standard
inputs(keyboard) and outputs, you use software to send calls to the
API, get output, and note down the system’s response. API tests are
very different from GUI Tests and won’t concentrate on the look and
feel of an application. It mainly concentrates on the business logic
layer of the software architecture.
6. Webservices
Web services are a type of API, which must be accessed through a network
connection. All webservices are API.
7. SOAP
SOAP is the acronym for Simple Object Access Protocol. SoapUI is an open-
source web service / API automation tools widely used in the software industry. You can
do functional, load, security and compliance tests on your API using
SoapUI. It is a XML based protocol for communicating between two
different systems.
8. REST
REST was designed specifically for working with components such as
media components, files, or even objects on a particular hardware
device. Any web service that is defined on the principles of REST can
be called a RestFul web service. A Restful service would use the
normal HTTP verbs of GET, POST, PUT and DELETE for working with
the required components. REST stands for Representational State
Transfer.
REST permits different data format such as Plain text, HTML, XML,
JSON, etc. But the most preferred format for transferring data is
9. CRUD
CRUD is a cycle for keeping records current and permanent. The principles of the CRUD cycle are defined
as CREATE, READ/RETRIEVE, UPDATE, and DELETE.
We can achieve CRUD operations in Leapwork by using the HTTP Request block.
1. CREATE:
It is used to generate new records. Use the POST method to create a resource.
2. READ:
Using the GET method to implement the “R” in CRUD is straightforward. It reads the data based on input parameters.
3. UPDATE:
Use the PUT method to create or overwrite a resource identified by a URI computed by the client. It is used to modify the
records.
4. DELETE:
It deletes a record where specified. When a resource is no longer useful, it can send a DELETE request to the resource’s
URI and delete that record.
