This paper addresses test application time (TAT) reduction for core-based stacked 3D chips. In contrast to the traditional method of testing non-stacked chips where the same test schedule is applied both at wafer test and at final test, stacked 3D chips need a pre-bond test schedule for each individual chip and a different post-bond test schedule where all chips are jointly tested. We consider a s

In the microscale structure of a porous electrode, the transport processes are among the least understood areas of SOFC. The purpose of this study is to evaluate the Lattice Boltzmann Method (LBM) for a porous microscopic media and investigate mass transfer processes with electrochemical reactions by LBM at a mesoscopic and microscopic level. Part of the anode structure of an SOFC for two componen

The simulated fuel cell has a porous electrode layer, gas flow duct and solid current collector. In terms of friction factor and Nusselt number, the characteristics of gas flow in the duct and heat transfer at heated catalyst surface were investigated by a computational calculation method. The effects of fuel cell current density, permeability of porous diffusion layers on the generation of heat,

This thesis deals with a multi-levl inventory system, consisting of one central warehouse and number of retails, facing stochastic demand.

It is well known that electroactive polymers (EAP) deform under electric fields. An advantage of EAP is that it may undergo deformations much larger than those capable by electroactive ceramics, however at comparatively low forces. As common for polymers, EAP exhibit time-dependent material behavior, i.e. an electro-viscoelastic effect. In the modeling the deformation as well as the electric poten

This paper suggests that there is a substantial risk when it comes to ensuring that we distinguish between gender-influenced experiences visible in qualitative research results/outcomes. The question is whether the object of inquiry in qualitative research in general allows other voices to be heard than the majority/mainstream voice. Or is there a risk that some voices will drown in the voice of t

Vi belyser olikheter och likheter i hur grundutbildningen styrs på fyra svenska tekniska högskolor. Vi jämför hur lärare och examinatorer väljs ut, hur medel fördelas och vilken roll programansvariga (eller motsvarande) har.

The ESS elliptical superconducting Linac consists of two types of 704.42 MHz cavities, medium and high beta, to accelerate the beam from 216 MeV (spoke cavity Linac) up to the final energy at 2 GeV. The last Linac optimization, called Optimus+, has been carried out taking into account the limitations of SRF cavity performance (field emission). The medium and high-beta parts of the Linac are compos

A multi-channel detector for narcotics and explosives using nuclear quadrupole resonance (NQR) is developed. Multiple measurement coils are used to estimate the radio frequency interference that is often present. The temperature dependency of the NQR frequencies is incorporated in the detector, allowing for uncertainties in the temperature estimate of the sample. In addition, the detector consider

Aviation is an important driver of individual and global mobility and emissions associated with transports. Recent studies indicate that a relatively small, highly mobile part of society may account for a large share of the total distances travelled. This phenomenon is as yet insufficiently understood. In addressing this situation, the paper reviews the processes leading to growth in mobility, and

Sophia Elisabeth Brenner's poems in Swedish, German, Latin, Italian and French made her well-known in Sweden and internationally and she was called 'the tenth muse'. Her collected poems were published in 1713 and posthumously in 1732. The paper explores how Mrs. Brenner made use of classical mythology and history when composing poems in Swedish. Antiquity provided her with a treasure of motives, b

The aim of the RAID project (Robot for Assisting the Integration of the Disabled) is to develop and demonstrate a prototype robotic workstation for use by disabled people. The RAID project is part of the European Community TIDE program (Technology for the socio-economic Integration of disabled and Elderly people). The robotized system is intended primarily for vocational use in an office environ
