Height of the frame plotted by inflectional tangents to the inflection points on peak branches is used as a peak maximum for calibration curve plotting. It is founded that systematic errors are not significant for the measurement of Tl (I) peak. In case of the Cd (II) peak the significant systematic error arising from tailing of the ascending part of Tl (I) peak is observed. We propose a method of systematic errors compensation. Systematic errors are estimated by peak series modeling. We use six parametric peak model with help of a priory information about signal shape and real values of resolution criteria and ratios of peaks heights. Peak shape is determined by difference method and ratios of peak heights by calibration curve.","PeriodicalId":319762,"journal":{"name":"2012 7th International Forum on Strategic Technology (IFOST)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133527211","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}

Polyethylene/modified LDH composites (PE/SDS-LDH) were prepared by melt blending and solution mixing method. Maleated polyethylene (PEgMA) was used to improve the compatibility between LDH and PE. The dispersion of LDHs in PE matrix was investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM). Thermal degradation of PE/SDS-LDH composites was characterized by thermogravimetric analysis (TGA). The results reveal that PE/PEgMA/SDS-LDHs microcomposites were obtained by melt blending method and PE/PEgMA/SDS-LDHs nanocomposites were prepared by melt blending PE with SDS-LDH/PEgMA master-batch obtained by solution mixing. Due to the thermal decomposition of LDHs at much lower temperature than PE, the degradation of composites begins at low temperature regardless of the dispersion of LDH in PE. The initial degradation temperature corresponding to 5% weight loss of nanocomposites is higher than that of microcomposites. Compared with microcomposites, the nanocomposites present the higher temperature corresponding to the maximum thermal degradation rate and more residues at the end of thermal degradation, indicating the better barrier properties and charring effects of nano-dispersed LDH.","PeriodicalId":319762,"journal":{"name":"2012 7th International Forum on Strategic Technology (IFOST)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132589726","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}

The phase-shifting method is based on obtaining several interferograms when the phase of reference wave is changed to known values. Accuracy of existing decoding algorithms depends on a setting of values of inserted phase shifts. However, it is difficult to determine an exact value of the phase shift in practice because of errors of devices performing a phase shift. In this paper an algorithm based on the step phase-shifting without a priori knowledge of phase shift is considered. This algorithm uses three interferograms obtained with arbitrary phase shifts.","PeriodicalId":319762,"journal":{"name":"2012 7th International Forum on Strategic Technology (IFOST)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128311251","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}
