The present study investigated four different filtering and differentiation sequences for the calculation of the higher derivatives from noisy displacement data when using a second-order Butterworth filter and first-order finite differences. These were: (1) the conventional sequence (i.e. filtering the displacement data and then differentiating); (2) filtering the displacement with a different ...

Urban atmospheric visibility is closely associated with our daily life, such as navigation and human health. In the traditional, visibility is measured by professionally trained people. Meters and technologies were proposed to replace the traditional measurement. Digital image processing technology is one of schemes to measuring visibility. Since the good visibility contains more detail data, t...

Contemporary digital hearing aids typically provide substantial benefit to children with mild to moderately severe hearing loss. However, for many hearing-impaired children, difficulty remains with certain aspects of speech recognition and production, such as the phonemes /s/ and /z/. The Phonak Nios micro-hearing aid utilises non-linear frequency compression (NLFC) technology, designed to lowe...

The frequency response of all oxide field-effect transistors with amorphous LaAlO3 on a crystalline SrTiO3 substrate is reported. The intrinsic cut-off frequencies of 4 lm gate-length devices are found to be approximately 17 MHz indicating that with gate length scaling gigahertz cut-off frequency is possible. The low cut-off frequency is primarily limited by the low effective mobility. The esti...

background: risk of malignancy index (rmi) is the best method for discriminating benign and malignant pelvic masses. the aim of this study was to determine the rmi for preoperative evaluation of pelvic mass. methods: this study was performed on 182 women with adenexal mass referred to yahyahnejiad hospital of babol university of medical sciences in iran from 2007 to 2009.the sensitivity, specif...

In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...

The paper analyses Vesna Parun’s humorous literature - satirical poetry and short forms such as aphorisms epigrams from the perspective of recent theoretical elaborations humour comic. interpretation is based on presumption that author’s poetic a kind political event can put pressure power systems in various areas human life. It encourages readers to question supposedly unquestionable worldview...

When determining lower limb loading (LLL) sources of error include the vibration of kinematic marker plates and how the motion and force data are digitally filtered. This study examined LLL during dynamic actions with reduced marker vibration using a tibial plate (TP) and two different levels of filtering severity (15 Hz and 35 Hz cut-offs). The increase of the filter cut-off frequency for the ...
