Aging and Sintered Layer Defect Detection of Discrete MOSFETs Using Frequency Domain Reflectometry Associated With Parasitic Resistance

Yun, Minghui (author), Yang, Daoguo (author), Cai, Miao (author), Yan, Haidong (author), Yu, Jiabing (author), Liu, Mengyuan (author), He, Siliang (author), Zhang, Kouchi (author)

Metal-oxide-semiconductor field-effect transistors (MOSFETs) undergo fatigue degradation under high thermal and electrical stresses. This process results in changes in their parasitic parameters, which can be detected using frequency domain reflectometry (FDR). Frequency domain impedance analysis is employed to characterize the various...

Multi-mode industrial soft sensor method based on mixture Laplace variational auto-encoder

Zhang, Tianming (author), Yan, Gaowei (author), Li, Rong (author), Xiao, Shuyi (author), Pang, Y. (author)

The industrially collected process data usually exhibit non-Gaussian and multi-mode characteristics. Due to sensor failures, irregular disturbances, and transmission problems, there are unavoidable outliers that make the data exhibit heavy-tailed characteristics. To this end, a variational auto-encoder regression method based on the mixture...

Bayesian Linear Inverse Problems in Regularity Scales with Discrete Observations

Yan, Dong (author), Gugushvili, Shota (author), van der Vaart, A.W. (author)

We obtain rates of contraction of posterior distributions in inverse problems with discrete observations. In a general setting of smoothness scales we derive abstract results for general priors, with contraction rates determined by discrete Galerkin approximation. The rate depends on the amount of prior concentration near the true function...

Li, B. (author), van der Heijden, H.M.H. (author), Jansen, S.J.T. (author), Yan, Juan (author), Boelhouwer, P.J. (author)

The private rented sector (PRS) plays an increasingly important role in accommodating young people and migrants in China’s metropolitan cities. However, the PRS in China is still underdeveloped, as evidenced by, e.g. a low degree of professionalisation, lack of basic rental laws and regulations, and poor housing experiences of tenants. The...

Surface gravity wave-induced drift of floating objects in the diffraction regime

Xiao, Q. (author), Calvert, R. (author), Yan, S.Q. (author), Adcock, T.A.A. (author), van den Bremer, T.S. (author)

Floating objects will drift due to the action of surface gravity waves. This drift will depart from that of a perfect Lagrangian tracer due to both viscous effects (non-potential flow) and wave–body interaction (potential flow). We examine the drift of freely floating objects in regular (non-breaking) deep-water wave fields for object sizes that...

Tensile behaviour of asymmetric bolted square hollow section column splices

Yan, R. (author), Xin, H. (author), Veljkovic, M. (author), Da Silva, Luís Simões (author)

In traditional end plate column splices, bolts are placed double symmetrically on the four sides of square hollow sections (SHS). In order to reduce the required gap between the façade and the column, the end plate could be flushed on one or two sides of SHS for the column along the façade or at the corner of a building, respectively. However...

Yan, J. (author), Stickel, L.S. (author), van den Hengel, L. (author), Wang, H. (author), Ravi Anusuyadevi, P. (author), Kooijman, A.M. (author), Liu, X. (author), Ibrahim, B. (author), Mol, J.M.C. (author), Taheri, P. (author), Mazzarella, L. (author), Isabella, O. (author), Savenije, T.J. (author)

The preferential orientation of the perovskite (PVK) is typically accomplished by manipulation of the mixed cation/halide composition of the solution used for wet processing. However, for PVKs grown by thermal evaporation, this has been rarely addressed. It is unclear how variation in crystal orientation affects the optoelectronic properties of...

Equivalent material properties of the heat-affected zone in welded cold-formed rectangular hollow section connections

Yan, R. (author), Mela, Kristo (author), Yang, Fei (author), El Bamby, H. (author), Veljkovic, M. (author)

A welded connection consists of three main material zones, the base material (BM), the heat-affect zone (HAZ), and the weld metal (WM). The strength of HAZ depends on the BM grade and manufacturing process, electrode grade, and welding parameters. Under certain conditions, HAZ has the lowest material strength, especially for high-strength...
