The adoption of this innovative technology in the pharmaceutical sector promises to solve several problems related to tracing and tracking systems at item level. Unfortunately, there are still some barriers limiting the largescale deployment of RFID technologies. One of these is related to very interesting research topics on the evaluation of potential effects of electromagnetic fields on drugs. In detail, this work aimed to analyze the impact of UHF RFID devices, used in tracing systems, on the molecular structure and potency of a commercial human insulin preparation, ActrapidTM. In order to investigate possible induced alterations of molecular structure, the Reverse Phase-High Pressure Liquid Chromatography and the Nuclear Magnetic Resonance spectroscopy have been mainly used in the experimental protocol. To obtain some indications about drug performance, in vitro cell proliferation assays have been also conducted. The experimental results, achieved by a protocol combining an accurate structural analysis on 5 min to 24 h irradiated drug samples with functional in vitro assays, have shown that the electromagnetic field generated by UHF RFID devices does not cause significant effects on ActrapidTM insulin. These findings are strongly encouraging the use of RFID-based technologies for item-level tracing systems in the pharmaceutical supply chain.","PeriodicalId":319141,"journal":{"name":"2010 5th Cairo International Biomedical Engineering Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122332692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do this for individuals with complex needs often requires that an approach is tailored to a specific user. However, in developing a domestic BCI it is necessary to consider the provision of an application which hides the complexity of the underlying science from the user whilst delivering acceptable levels of interaction for many. This is not an unusual circumstance in the realm of assistive technology. We present a cohesive test suite which allows the development team to assess what constitutes an acceptable level of accuracy in a four-way command interface using steady-state visually evoked potentials (SSVEP). It also facilitates a uniform assessment of the level of accuracy achieved by a specific user operating a BCI and provides a means of contrasting and selecting performance parameters in order to enhance user performance.","PeriodicalId":319141,"journal":{"name":"2010 5th Cairo International Biomedical Engineering Conference","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114066034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wavelet decomposition of MECG signals segments the clinical information content at different Wavelet subbands or scales. At subband levels or scales multivariate data matrix are formed using Wavelet coefficients extracted from the same scales of MECG signals. At each subband matrix or scales, PCA is applied for noise elimination. To retain essential diagnostic components, matrices comprising of lower order Wavelet subbands are processed with reduced set of principal component (PC). Qualitative performance is evaluated and quantitative performance of denoising effect is measured by input/output signal-to-noise ratio (SNR). Signal distortion measures are evaluated using percentage root mean square difference (PRD), Wavelet weighted PRD (WWPRD) andWavelet energy based diagnostic distortion measure (WEDD). The proposed algorithm is tested with database of CSE multilead measurement library. The results show significant improvement in denoising of MECG signals with the lowest PRD of 3.488 and high SNR improvement of 34.279 dB.","PeriodicalId":319141,"journal":{"name":"2010 5th Cairo International Biomedical Engineering Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131880051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A difficult is that the CAD-related sound is very weak and recordings are often contaminated by noise. The current study analyses the noise contamination of 633 stethoscope recordings from a clinical environment. Respiration noise, ambient noise, recording noise and abdominal noise were identified in the recordings and were classified according to duration and intensity. To monitor how noise influences the classification performance AR-pole magnitudes were extracted from both the 25–250 Hz frequency band and the 250–1000 Hz frequency band. The classification performance was quantified by the Area Under the receiver operating Characteristic (AUC). Ambient noise was present in 39.9% of the recordings and was the most common noise source. Abdominal noise was the least common noise source, present in 10.8% of the recordings. The best pole, with respect to detection of CAD, extracted from the 250–1000 Hz frequency band was sensitive to noise, since the AUC dropped from 0.70 in to 0.57 when noisy recordings were included. Contrary the best pole from the 25–250 Hz frequency band was relatively robust against noise, since the AUC dropped from 0.73 to only 0.70 when noisy recordings were included. The study demonstrated that noise contamination is a frequent problem and that features from lower frequency bands are more robust against noise than features from higher frequency bands.","PeriodicalId":319141,"journal":{"name":"2010 5th Cairo International Biomedical Engineering Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128957371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
