A jet engine is a reaction-type engine that generates thrust by jet propulsion. Most jet engines are internal combustion engines that operate based on Newton’s third law. Broadly speaking, jet engines include rocket engines and air jet engines. Rocket engines have their fuel and oxidizer carried by the aircraft, including solid-fuel rocket engines and liquid-fuel rocket engines, and they are characterized by the ability to operate outside the atmosphere; air jet engines do not carry their own oxidizer but obtain air from the atmosphere as the oxidizer, including ramjet engines, pulse engines, turbojet engines, and turbofan engines, etc. The most commonly used air jet engine in modern air transport aircraft is the turbofan engine, which is characterized by high thrust, low noise, and low fuel consumption.

A wind turbine [1] is a type of turbine that uses wind energy as its power source. An aerospace research institution in Wellbrihan, Massachusetts, USA, has developed a wind turbine whose cost of generating electricity is only half that of conventional turbines.
The new design of the wind turbine produces electricity of the same quality as traditional wind turbines, but the diameter of its blades is only half that of the latter. The smaller blade size and other factors enable the new turbine to be more densely clustered on the same area of land as traditional turbines, thereby increasing the electricity output per acre of land.

The driver module (Driver Module) is an auxiliary program used in unit testing to simulate the upper-level components of the module under test. It falls within the scope of traditional unit testing terminology. Its main function is to receive test data and pass it to the module under test, execute it, and output the results to verify the module’s functionality. It is often used as an entry point in the testing framework [1].
This module automatically calls the tested function by simulating user interface operations and can execute the test process without interacting with the actual interactive interface. In unit testing, it needs to be combined with the stub module (stub) to respectively replace the upstream and downstream components of the module under test. The separation principle should be used simultaneously with the driver module and the stub module [2].
The driver module can be implemented at the code level through the main program. For example, in C language or Java, the main function is used to pass test parameters and receive and verify the returned results. In test cases, module verification can be completed by simulating the headlight function or browser interaction.
Traditional unit testing includes the driver module (driver) and the stub module (stub). The purpose of the driver module is very simple; it is to access the attributes and methods of the class library to detect whether the function of the class library is correct;
Normal 0 0 2 false false false EN-US KO X-NONE MicrosoftInternetExplorer4 If the functions in the module under test are provided for other functions to call, when designing test cases, a driver module (Driver) should be designed.
For example: The driver module (Driver) can automatically call the functions in the module under test by simulating a series of user operation behaviors, such as selecting a certain option on the user interface or pressing a certain button. The settings of the driver module (Driver) make the testing of the module not need to interact with the actual user interface.

High-performance computers with high throughput, high utilization rate and low latency
High-throughput computers are a new type of high-performance computer that is suitable for emerging application loads such as those of the Internet big data. They can globally control the processing of high-concurrency requests under strong time constraints. Their core characteristics are the guarantee of concurrency, real-time, and determinism.
The characteristics of high-performance computing in traditional scientific and engineering computing applications include: single tasks, infrequent changes in load, large single-task computing volume, and good locality of computation. While high-throughput computing in data centers is mainly applied in emerging scenarios such as the Internet and Internet of Things, its characteristics are: diverse tasks, single tasks often having streaming computing features; relatively small computing volume, but a huge number of concurrent tasks and data scale; and processing requirements having real-time nature.
The development goal of traditional high-performance computers is to increase speed, that is, to shorten the running time of a single parallel computing task; while the goal of data center application systems is high throughput, that is, to increase the throughput of tasks or data processing per unit time. High-performance computers with this performance metric of “doing more computing” are called high-throughput computers.

A Programmable Logic Controller (PLC) is a universal industrial automatic control device developed based on microprocessors, integrating computer technology, automatic control technology, and communication technology [13]. It uses programmable memory as the internal instruction memory device and has functions such as logic, sequencing, timing, counting, and arithmetic operations. [13]
The core of a PLC consists of a central processing unit, memory, input/output modules, and communication interfaces [1-3], supporting various programming languages such as ladder diagrams and function block diagrams, and is widely used in automotive manufacturing, energy and chemical industries, and mechanical processing, etc. [2] [6] [10] [12]. According to its composition structure, it can be divided into integrated PLC and modular PLC [13]. It has the characteristics of high reliability, strong anti-interference ability, variable control programs, and good flexibility [13]. It was developed based on relay-contactor control. In 1969, the American Digital Equipment Corporation developed the first programmable logic controller [13]. Since then, this new type of industrial control device has been quickly promoted and applied in other industrial fields in the United States [13]. In 1971, Japan introduced this new technology and began to produce programmable logic controllers [13]. In 1973, Western European countries also began to develop and produce programmable logic controllers [13]. In 1974, China began to develop programmable logic controllers and started to apply them in industrial production [13]. In the early 1980s, it has been widely used in advanced industrial countries [5]. From the 1980s to the mid-1990s, it was the fastest-growing period [5]. In the late 20th century, it was more suitable for the needs of modern industry [5]. In the 21st century, with the promotion and implementation of the IEC61131 series standards, especially the IEC61131-3 programming language standard, PLC has entered the era of openness and standardization. [14]
With the development of modern science and technology, PLC is not only used for sequential logic control, but can also receive various digital signals and analog signals, perform logical operations, function operations, and floating-point operations, etc. [13], and is one of the three pillars of modern industrial automation.

The measurement control system is an essential component of the impulse voltage (current) test generator, and its design level directly reflects the technical capability of the equipment. The charging and control functions are integrated within the unit, including the control cabinet, operation console, and measurement unit. It uses thyristor controllers and FX2n programmable logic controllers, and the design of optical fiber cables ensures stable operation in an interference environment. Due to the significant differences in industry application scenarios, the functional requirements are clearly differentiated. The standardized design of the system becomes a key technical consideration, and it needs to take into account the scalability architecture and the development of general modules.
The test force measurement system is composed of high-precision load sensors, measurement amplifiers, A/D conversion modules, and stabilized power supplies. The displacement measurement system includes photoelectric encoders, frequency doubling shaping circuits, and counting circuits. The multi-component signal processing realizes the functions of computer display, control, and data processing [1]. The system model adopts the MCS-2/000 structure, and the standard model MCS-A/B where A represents the type of control unit (divided into electrical control, touchscreen intelligent control, and measurement and control integration three types), and B corresponds to the controlled object. The charging device is divided into GC (large current full bridge type) and GV (high voltage voltage doubling type). For example, GC-6008 indicates a device with a maximum charging voltage of 60 kV and a maximum power of 8 kVA. The control unit is equipped with optional electrical control, fully automatic touch screen or intelligent measurement and control integration systems.
