A 3mm band detector indoor calibration system is introduced in this paper, which is based on a STM32 embedded system. This embedded control system includes noise source control circuit, database circuit, a real time clock circuit, humidity and temperature sensor circuit, PS/2 interface circuit and SD card interface circuit. And a database, which contains radiation characteristics of metal targe...

Critical views are presented on some nucleo-cosmochronological questions. Progress has been made recently in the development of the 187 Re-187 Os cosmochronometry. From this, there is good hope for this clock to become of the highest quality for the nuclear dating of the Universe. The simultaneous observation of Th and U in ultra-metal-poor stars would also be a most interesting prospect. In co...

This paper considers bidding behavior in a repeated procurement auction setting. We study highway procurement data for the state of California between December 1994 and October 1998. We consider a dynamic bidding model that takes into account the presence of intertemporal constraints such as capacity constraints. We estimate the model non-parametrically and assess the presence of dynamic constr...

For a number of years a new scientiJc unity has been developing frotn a synthesis itz which chemistry and physics have become closely lirlked with biology. On the biological side cytologists are concerned with what happens to the nucleo-proteins and the nucleic acids present in plant and animal cells. These compounds are of great interest to biochemists atld biophysicists, and during I953 impor...

The very end of every chromosome is a region called the telomere. Telomeres are nucleo-protein complexes containing specific DNA repeat sequences whose lengths are strongly believed to give indications to aging and tumor progression. In order to study the role these repeat sequences play in the cell, we developed a fluorescence microscopy imaging system and associated image analysis methods to ...

Model Predictive Control (MPC) is an established control technique in a wide range of process industries. The reason for this success is its ability to handle multivariable systems and systems having input, output or state constraints. Neverthless comparing to PID controller, the implementation of the MPC in miniaturized devices like Field Programmable Gate Arrays (FPGA) and microcontrollers ha...

Based on people’s demand for indoor air quality monitoring, an ambient intelligence detection system with STM32F103C8T6 microcontroller as the core controller is designed, which can monitor current temperature, humidity, suspended particles (PM10) and toxic harmful gases in real time, accurately effectively. And environment transmitted to computer display through Bluetooth, so warn people time ...

With the development of science and technology, people’s demand for material culture is also increasing. The radio with good sound quality, easy portability, certain technological content, moderate price can meet market well. embedded digital tuning based on stm32 uses a 32-bit chip fast processing speed, convenient development, high-cost performance. At same time, it combined TDA audio decodin...
