A finite measurement time is at the origin of transient (sometimes called leakage) errors in nonparametric frequency response function (FRF) estimation. If FRF varies significantly over resolution experiment (= reciprocal time), then these transients (leakage) cause important bias and variance estimate. To decrease errors, several local modeling techniques have been proposed literature. This ar...

Cochannel interference introduced by frequency reuse under space division multiple access can be reduced by controlling the frequency sharing according to the users’ spatial separability. The system avoids placing highly correlated users in space into the same spatial multiplexing group. This paper describes a user spatial compatibility evaluation criterion based on channel matrix structure ana...

Let K be a complete discrete valuation field with finite residue field F of order q. We call such a field a local field. The geometric Frobenius FrF is the inverse of the map a 7→ a in the absolute Galois group GF = Gal(F̄ /F ). The Weil group WK is defined as the inverse image of the subgroup 〈FrF 〉 ⊂ GF by the canonical map GK = Gal(K̄/K) → GF . For a scheme XK of finite type over K, the l-adic...

Vehicle manufacturers worldwide are increasingly relying on road simulation facilities that put simulated loads and stresses on vehicles and subassemblies in order to shrink development time. Road simulation algorithm is the key point of developing road simulation system. With the rapid progress of computer technology, more complex algorithms can be utilized. First, multi-input exciting method ...

BACKGROUND Diabetes mellitus is a disease lack of insulin, which has severely delayed and impaired wound healing capacity. In the previous studies, various types of scaffolds and growth factors were used in impaired wound healing. However, there were several limitations to use them such as short half-life of growth factors in vivo and inadequate experimental conditions of wound-dressing materia...

Three different calibration approaches were applied in HPLC/MS/MS using electrospray ionization for the determination of 14 diverse pesticide residues at different levels in a variety of food matrixes. This study was conducted as part of a 4 day training course for 17 chemists to learn the "quick, easy, cheap, effective, rugged, and safe" (QuEChERS) approach to pesticide residue analysis in foo...

Frequency Response Function (FRF) estimation from measured data is an essential step in the design, control, and analysis of complex dynamical systems, including thermal motion systems. Especially for systems that require long measurement time, missing samples record, e.g., due to interruptions, often occur. The aim this paper achieve accurate identification non-parametric FRF models periodical...

The forced frequency analysis is very important in the design of automotive structures. In particular, the Frequency Response Functions (FRF) computation is an important step in determining Noise, Vibration and Harshness (NVH) of any automotive vehicle. In general, the CAE engineer must address the severity and compliance of the design limits set in the NVH environment. Usually, a CAE engineer ...
