Extended tecdatr language distributed lag nonlinear model (dlnm) study of air pollution modeling application of the effect of temperature on mortality
Original link:http://tecdat.cn/?p=23564 Environmental stressors often show time lag effect, which requires a sufficiently flexible statistical model to describe the time dimension of exposure response relationship. Here, we develop a distributed hysteresis nonlinear model (dlnm), which is a modeling framework that can represent nonlinear exposure response dependence and hysteresis effects at the same time. This method […]

Newton’s law of cooling
Newton’s cooling theorem describes the mathematical model of the temperature of the object changing with time under the initial temperature of the environment and during the natural cooling process of the object, which is expressed by the formula as follows: $$ \frac{dT(t)}{d(t)} = k(T(t)H) $$ Where h is the ambient temperature and K is the […]

First try! Implement sniffer of DDC protocol in spirit 1
First try! Implement sniffer of DDC protocol in spirit 1 We started with an intelligent edge computing systemEdgerOSSpirit 1, through which we can connect applications with devices. Through JavaScript applications, we can control the connected devices. Before, we were ready to make a device based onSDDCThe infrared temperature sensing device of the protocol is connected […]

Raspberry pie GUI display temperature monitoring – pyside / pyqt / QML
This paper introduces how to use Python and QT to develop GUI program on raspberry pie. The function of the program is to display the temperature curve of DS18B20 module. The development environment still uses pycharm to write Python code and remote development, and then uses qtcreator to write QML interface. 1. New project 1.1 […]

Learning data docking of 3D visualization from scratch (2)
In the daily use of Internet products, many are completed by the interaction of front and rear data. When it comes to data interaction, we have to mention Ajax and websocket. They are powerful tools for data interaction. What are they? Ajax has been mentioned in the last article. What is websocket?WebSocketHTML5 is a new […]

Learning data docking of 3D visualization from scratch (3)
MQTTIt is one of the four data docking methods supported by thingjs platform. Mqtt, also known as message queuing telemetry transport, is a message protocol based on publish or subscribe paradigm under ISO standard (ISO / IEC PRF 20922), which can be regarded as “bridge of data transmission”. Mqtt is a lightweight protocol. The center […]

Simulated annealing algorithm Python Programming (1) multivariable function optimization
1. Simulated annealing algorithm Simulated annealing algorithm draws lessons from the idea of statistical physics. It is a simple and general heuristic optimization algorithm, and has probabilistic global optimization performance in theory. Therefore, it has been widely used in scientific research and engineering.Annealing is a process in which the metal cools slowly from the molten […]

How can the computer hardware check that the temperature is normal and the heat dissipation is good?
Someone asked, how can I detect the temperature without a thermometer on my computer? How to check that the hardware temperature of the computer is normal and the heat dissipation is good? In fact, there is a temperature sensor inside the computer. The temperature is obtained by reading the sensing data of the sensor. Here […]
