The realization of virtual prototyping of electronic packages depends on the capability and reliability of multiphysics modeling. This paper focuses on the methods and solutions of combined thermal and thermo-mechanical modeling. The package-level thermal behaviors for various kinds of packages are discussed first through the thermal simulation. The impact of internal package design on thermal ...

in this study, a new method for joining aluminum tubes in subsurface structures using steel converting and aluminum welding are presented and reviewed. but near the weld area is under high thermal cycle and will cause residual stresses in heat affected zone. therefore for assessment of proposed connection from the perspective of residual stress by using the finite element method welding of tube...

this paper was aimed to address the modeling of effective thermal conductivity and viscosity of carbon structured nanofluids. response surface methodology, d_optimal design (dod) was employed to assess the main and interactive effects of temperature (t) and weight percentage (wt %) to model effective thermal conductivity and viscosity of multi wall and single wall carbon nanotube, cvd and rgo g...

Current architecture assessment models focus on either architecture maturity or architecture alignment, considering the other as an explaining sub-variable. Based on an exploratory study, we conjecture that both alignment and maturity are equally important variables in properly assessing architecture organizations. Our hypothesis is that these variables conceptually differ, correlate, but do no...

Background: Subjective well-being and satisfaction with life can help individuals to achieve more success in their lives and enjoy better supportive social relationships and higher levels of physical and mental health. The present study aimed to determine the relationship of social maturity with sexual satisfaction, well-being, and controlling behaviors through the mediating role of marital com...

Thermal errors are among the most significant contributors to machine tool errors. Successful reduction in thermal errors has been realized through thermal error compensation techniques in the past few decades. The effectiveness of thermal error models directly determines the compensation results. Most of the current thermal error modeling methods are empirical and highly rely on the collected ...

In the context of the trend toward delayed parenthood, this study examines whether older maternal age is associated with greater psychological maturity and whether greater psychological maturity provides any adaptive benefit during the transition to motherhood. A sample of 240 predominantly English-speaking Australian women in a metropolitan area expecting their 1st baby (mean age = 32.81 years...

Thermal modeling of transformer is necessary to ensure the optimal design and cost of manufacture of transformer. Either of the empirical formulae available from the standards and practical measurement techniques used in the industries as an alternative to the formulae will not be able to answer the problem exactly and hence the development of software based thermal modeling techniques that use...

The Hikurangi subduction zone is capable of producing moderate to large earthquakes as well regularly repeating slow slip events. However, it unclear what structures host these different styles along the margin. Here we address whether splay faults can seismic at shallow (<1 km) depth by investigating P?paku fault, sampled during International Ocean Discovery Program Expedition 375. We use biom...
