The indoor air temperature of greenhouse is an important parameter in environmental monitoring. Existing research on it has many, and the mathematical models have been made. But the obtained models do not apply to the northern areas features of dry and cold. On the basis of previous studies, the indoor air temperature model of greenhouse will be re-modeling by using the regression analysis meth...
Little is known of the patterns of physical activity, standing and sitting by office workers. However, insight into these behaviours is of growing interest, notably in regard to public health priorities to reduce non-communicable disease risk factors associated with high levels of sitting time and low levels of physical activity. With the advent and increasing availability of indoor tracking sy...
Swarms of indoor flying robots are promising for many applications, including searching tasks in collapsing buildings, or mobile surveillance and monitoring tasks in complex man-made structures. For tasks that employ several flying robots, spatial-coordination between robots is essential for achieving collective operation. However, there is a lack of on-board sensors capable of sensing the high...
Indoor Air Quality perception in education centres has being a special concern based on their high occupancy and lack of ventilation. This study aims to present an overview 20 relevant previous studies carried out the last 5 years regarding monitoring evaluating centres. analysis focuses four specific aspects: general description each study, ventilation typology, indicators measured number loca...
Microcontroller is widely used in the intelligent life of modern society. Intelligent development based on to solve actual needs people’s life, work, study and other fields core application. Therefore, it a task for researchers understand structure performance microcontroller, develop software, be familiar with method process microcontroller. And that mind, this paper designs produces physical ...
بررسی ارتباط بین غلظت ذرات معلق در هوای داخل بیمارستان کودکان تهران و هوای آزاد اطراف آن در سال 1386
Background and Objectives: In recent years exposure to fine airborne particles has been identified as an important factor affecting human health. Epidemiological studies have showed that the aerosol laden air can be an agent for microorganisms’ dispersion. Ignoring internal sources, ambient air quality significantly affects indoor air quality. Since people spend most of their times in the indoo...
