In this paper, a new cybernetic control technology that can be used in complex software systems will be introduced. In this approach, the software systems are governed by cybernetic control objects and the class libraries defining the types of these cybernetic control objects are produced by special meta-programming platforms. In this approach, the requirements of the software to be developed are received from the programmer by meta-programming systems before coding. Actually, the cybernetic control objects have standard design and properties and the programmers only determine the quantities and the locations of these properties before library production process. Then, the meta-programming platforms build project-specific class libraries based on previously determined code templates. By this way, the cybernetic control objects are constructed with optimal memory and they can receive feedback about ongoing operations on the process. With the help of the feedback coming from the process, the control objects steer the process in the line of the programmer directives. By this way, the control of the programmer on the software increases significantly. In addition, in this paper, a typical application of this approach to the multithread programming will be introduced.

“…It is known as Dynamic Thermal Management (DTM). It is a set of techniques that controls the processor temperature and prevents it from overheating; e.g., reducing of the CPU clocking (DFS-Dynamic Frequency Scaling) or supplying voltage (DVS-Dynamic Voltage Scaling) leads to reduce CPU processing speed and to decrease its temperature [9][10][11][12][13]. DFS and DVS are based on CPU temperature monitoring using an integrated sensor.…”

The monitoring of processor temperature is crucial to increase its efficiency. One of the novel approaches is use the information not only about the CPU (Central Processing Unit) thermal state, but also about changing environmental conditions. The additional temperature difference sensor to monitor thermal changes in the processor environment is necessary. The sensor dedicated for active heat sink, often used inside laptops, was designed, fabricated and investigated. To fulfill the requirements and to match to the specific shape of the active heat sink, the hybrid sensor was proposed. It was composed of six thermocouples and fabricated using thick-film and LTCC (Low Temperature Cofired Ceramic) technology combined with wire thermocouples. Thick-film/LTCC flat substrates with thermoelectric paths ensured good thermal contact between the sensor and the monitored surface. The thermoelectric wires allowed adjusting the sensor to the complicated shape of the active heatsink. Three different versions of the sensor were realized and compared. All of them seem to be suitable for measuring the temperature difference in the given application and they can be used in further works.

“…In recent years, continuous improvements in thermal management technology for electronic devices, such as tablet PCs, smart-phones, and various kinds of mobile electronic devices, have been developed to meet the increasingly higher heat flux requirements due to their dramatic reduction in size [1][2][3]. 1 One solution that has been devised by researchers [1,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] to meet the high heat flux duty is flat-micro heat pipes (hereafter FMHPs).…”

This paper presents a theoretical investigation of the thermal characteristics of flat-micro heat pipes (FMHPs) with multi-heat sources and sinks. Analytical solutions of the pressure and the temperature distributions of FMHPs with multi-heat sources and sinks were obtained based on the modified liquid pressure drop. The solutions were used to identify the key engineering parameters of a mesh wick with microscale length that affect the maximum heat transfer rate of the FMHPs with multi-heat sources and sinks. The effects of the key engineering parameters on the maximum heat transfer rate of the FMHPs were presented for two limits. The first limit is the capillary limit and the other is the allowable maximum temperature limit which is used to ensure that the maximum surface temperature of the FMHP with the maximum heat transfer rate calculated at the capillary limit does not exceed the allowable maximum temperature of the electronic components. Finally, the theoretically results for the optimized wick structure for the corresponding maximum heat transfer rate and the surface temperature distribution of the FMHP were compared for the capillary limit only and for the maximum temperature limit cases, respectively.
