Thermal requirements of Dermanyssus gallinae (De Geer, 1778) (Acari: Dermanyssidae)

open access: yesRevista Brasileira de Parasitologia Veterinária, 2008
The thermal requirements for development of Dermanyssus gallinae were studied under laboratory conditions at 15, 20, 25, 30 and 35°C, a 12h photoperiod and 60-85% RH. The thermal requirements for D. gallinae were as follows.

Germination Parameters of Selected Summer Weeds: Transferring of the AlertInf Model to Other Geographical Regions

open access: yesAgronomy, 2021
Effective weed management depends on correct control timing, which depends on seedling emergence dynamics. Since soil temperature and soil moisture are the two main factors that determine weed germination, the hydrothermal time model can be used to ...

Evaluation of germination characteristics and determination of cardinal temperatures of poppy (Papaver somniferum) seed [PDF]

open access: yesعلوم و فناوری بذر ایران, 2017
The aim of this study was to quantify the response of germination rate to temperature and to find cardinal temperatures required for different germination percentiles in Papaver somniferum. Four models of non-linear regression [Quadratic, Segmented, Beta

Capacity of Temperature-Based Covert Channels [PDF]

open access: yesIEEE Communications Letters, 2011
Covert channels aim to hide the existence of communication. Recently, Murdoch proposed a temperature-based covert channel where information is transmitted by remotely inducing and measuring changes of temperature of an unwitting intermediate host.

Monitoring temperature in FPGA based SoCs [PDF]

open access: yes2005 International Conference on Computer Design, 2006
FPGA logic densities continue to increase at a tremendous rate. This has had the undesired consequence of increased power density, which manifests itself as higher on-die temperatures and local hotspots. Sophisticated packaging techniques have become essential to maintain the health of the chip.

The effect of the triangular rib usage in the plate fin heat sinks on the pressure drop, base plate temperature, and entropy generation

open access: yesEuropean Mechanical Science, 2023
Improving the thermal efficiency in plate fin heat sinks (PFHS) results in a reduction in the weight, volume and cost of the heat sink. This ensures long life and reliable operation of the cooled equipment.

Temperature-Based Deep Boltzmann Machines [PDF]

open access: yesNeural Processing Letters, 2017
Deep learning techniques have been paramount in the last years, mainly due to their outstanding results in a number of applications, that range from speech recognition to face-based user identification. Despite other techniques employed for such purposes, Deep Boltzmann Machines are among the most used ones, which are composed of layers of Restricted ...
