A question is raised about the premature acceptance of the standard cosmological model, the ’ΛCDM’ paradigm; the non-metric, or semimetric, theory of Self Creation Cosmology is offered as an alternative and shown to be as equally concordant as the standard model with observed cosmological constraints and local observations. In self-creation the Brans Dicke theory is modified to enable the creat...

The study of wave power generation is more and popular in modern science technology for the new renewable energy, recent years. Designing devices with high conversion efficiency stability, improving technical level commercialization are both scientifically interesting potentially useful. Here we achieve stability equipment by establishing one nodding duck energy system a tank. Equipped ultrason...

The comprehensive pipe corridor could realize the unified planning and construction of electricity, gas communication, save urban land resources beautify landscape. However, due to narrow space numerous pipelines in corridor, once power cable fired, it would cause serious losses. This paper presented a wireless infrared temperature measuring system for based on radio frequency communication tec...

An aging society is the challenge we will face and deal with. It necessary important to explore problems solutions faced by an society. In response this phenomenon, designed IoT home smart robot based on ESP8266 STM32 improve quality of life elderly. The can realize functions such as environmental monitoring, fire warning, electrical power distribution, light control, auxiliary weight lifting, ...

In this paper, the changes of oxidation temperature sulfide corrosion and deficiency distributed optical fiber application were analyzed. The test platform was established, performance simulation realized. hardware part control system used STM32 as controller, software based on process characteristics controlled object, using MATLAB to carry out PID, fuzzy, fuzzy PD plus I, PID algorithms, thei...

Recently, the Internet of things (IoT) has become extensively used in our daily lives. This technology offers a new vision future internet where devices are interconnected and can communicate together. A big number these complicates firmware update makes it more expensive since each node must be updated locally. Nevertheless, there many cases cannot change their location to upgrade locally due ...

Simple control of a stand-alone variable speed wind turbine with permanent magnet synchronous generator (PMSG) is presented in this paper. PMSG fed different types loads by means converter where switched mode rectifier connected to the PMSG, boost DC-DC converter, and voltage source inverter (VSI). The operated at measured it tested estimated which based on power calculation power, generating e...

In order to enhance the control stability and anti-interference ability of quadcopter, this paper presents a quadcopter based on double-layer PID control, designs with STM32 as main controller, simulates verifies its system attitude. Firstly, nonlinear attitude mathematical model aircraft is established by four-element method, relationship between angle angular velocity obtained solving, so tha...

The digging depth is an important factor affecting the mechanized garlic harvesting quality. At present, of combine harvester (GCH) adjusted manually, which leads to disadvantages such as slow response, poor accuracy, and being very dependent on operator’s experience. To solve this problem, paper proposes a machine vision-based automatic control system for original device. uses improved YOLOv5 ...

Recent advances in state-of-the-art ultra-low power embedded devices for machine learning (ML) have permitted a new class of products whose key features enable ML capabilities on microcontrollers with less than 1 mW consumption (TinyML). TinyML provides unique solution by aggregating and analyzing data at the edge low-power devices. However, we only recently been able to run microcontrollers, f...
