This thesis investigates the problem of regulating the temperature of a conditioned space using a Solar Assisted Air Conditioning Systems (SAACS) prototype located at Cabo Rojo, Puerto Rico. The SAACS Prototype consists of a 66 flat plate solar collector array with 115.4 m 2 of selective surface area, a 35 kW single-effect lithium-bromide absorption chiller, a 84 kW cooling tower, a 50 kW auxil...

One of the most important factors of users comfort inside building is air temperature. From the other side one of the most biggest position in home budget is price for heat. Mutually exclusive indices are the cause that the control of temperature task using the smallest amount of energy as it is possible is very difficult. In this paper is presented simple model of temperature changes inside bu...

The objective of this paper is to design and fabricate a micro-cooler to provide integral cooling to electronics or Microelectromechanical Systems (MEMS) type components utilizing current MEMS technologies. A three-port capillary pumped loop (CPL) was analyzed and fabricated from silicon and quartz for this purpose. An analytical study of the device is presented in support of this design. This ...

Through our project we are showing the control of constant temperature according to the desired value (set point) in a closed loop using PID controller system. For this, we are using a microcontroller, a temperature sensor for sensing the temperature of the closed loops. By using the microcontroller we compare the desired value with current value and it is displayed in the LCD. Also to provide ...

1106 CLINICALCHEMISTRY,Vol. 26, No. 7, 1980 knowledge of the relative precision characteristics of the two compared methods (2-4). When such information is lacking, the best that can be done is probably to put A equal to 1. Unless there is an uncommonly large discrepancy in precision between the two methods, this will be more realistic in comparison studies than the assumption, implicit in the ...

In the single-phase multiferroics, the coupling between electric polarization (P) and magnetization (M) would enable the magnetoelectric (ME) effect, namely M induced and modulated by E, and conversely P by H. Especially, the manipulation of magnetization by an electric field at room-temperature is of great importance in technological applications, such as new information storage technology, fo...

This Technology Installation Review describes the installation of a wireless temperature sensor network at the U.S. Environmental Protection Agency (EPA) National Health and Environmental Effects Research Laboratory in Duluth, MN. The objective of the wireless sensor demonstration was to showcase the technology so the experiences with the technology and benefits of the project may be replicated...

Thermoregulation is one of the most vital functions of the brain, but how temperature information is converted into homeostatic responses remains unknown. Here, we use an unbiased approach for activity-dependent RNA sequencing to identify warm-sensitive neurons (WSNs) within the preoptic hypothalamus that orchestrate the homeostatic response to heat. We show that these WSNs are molecularly defi...

B Abstract. Recently, in a paper of Chylla and Haase 2], a model of a multi-product semibatch polymerization reactor has been developed which is representative of those found in the speciality chemical processing industry. One of the aims in these processes is to keep a certain reaction temperature setpoint, in order to t the quality requirements for the polymer. In the present paper, the optim...
