This paper investigates the lineshape of a CMS laser for two distinct types of frequency noise. In the first case the investigation analyzes on the low-pass filter, the frequency noise level is a constant δo below a cutoff frequency but zero above this threshold. In the second case on high-pass filter the frequency noise level is a constant δo above a cutoff frequency but zero below this threshold. Investigations observed inspire us to focus for separation of the frequency noise spectrum into two regions wherein due to the effect of noise on the lineshape is radically different in the slow modulation area in a left side of the diagonal line where the noise contributes to the laser linewidth, with a Gaussian shape, and the other one the fast modulation area in a right side of the diagonal line, where the noise contributes only to the wings of the line (sidebands) and not to the linewidth, thus transforming the lineshape from Gaussian to Lorentzian.","PeriodicalId":358440,"journal":{"name":"2011 IEEE Symposium on Business, Engineering and Industrial Applications (ISBEIA)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131714630","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}

Three agroforestry components involved in this study include (1) Karas (Aquilaria malaccensis) monoculture, (2) Karas intercropped with lemongrass, and (3) Karas intercropped with guava. Three replicative plots measuring at 6 m × 5 m were established for each component. Each plot consists of a total of 90 Karas trees. The diameter at breast height (DBH) of Karas trees was measured in each plot. From the field measurements, the means of tree DBH in all three plots are 5.74 cm, 4.23 cm and 6.65 cm, respectively. Analysis of variance (ANOVA) revealed that there is a significant difference in the mean DBH of Karas tree between components (P≤0.05). Karas intercropped with guava recorded a significantly greater DBH than the other two components (P≤0.05). This could be due to the intercropping effects of Karas with different components of agroforestry system. The results from this study will be used for subsequent investigation in the assessments of growth performance of Karas under different intercropping components.","PeriodicalId":358440,"journal":{"name":"2011 IEEE Symposium on Business, Engineering and Industrial Applications (ISBEIA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130983955","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 factors of interest in this study were components of job burnout, which included emotional exhaustion, depersonalization, and diminished personal accomplishment; and job performance of nurses. Survey questionnaire was used to collect the data needed for analysis, which was adapted and modified from Maslach Burnout Inventory (MBI). The respondents were nurses from the private hospital at Perak. Data collected was analyzed using SPSS version 12.0 for Window, and the methods of analysis were Pearson correlation and multiple regression analysis. The findings of this study revealed that there were significant correlations between emotional exhaustion (r=0.305, p=0.006), depersonalization (r=0.239, p=0.031) and job performance. Meanwhile, this study failed to establish a relationship between diminished personal accomplishment and job performance. On the other hand, multiple regression analysis showed that emotional exhaustion was the dominant factor that affecting job performance (β=0.305, r2=0.093). In conclusion, nursing profession is at high risk of job burnout or particularly emotional exhaustion, which will jeopardize nurses' job performance and eventually contribute to deterioration in quality of care.","PeriodicalId":358440,"journal":{"name":"2011 IEEE Symposium on Business, Engineering and Industrial Applications (ISBEIA)","volume":"93 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126137247","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}

Hollow and solid, both types of modular block units are used in dry-stacked facing columns. Nowadays, Hollow concrete units are being implicated frequently because of its cost-effectiveness and other technical advantages. The cavities of hollow concrete units are filled with natural (fresh) aggregates for better shear resistance. The use of fresh aggregates as in-fillers in retaining wall constructions is expensive and unsustainable (annihilation of natural resources). This study mainly focuses on frictional behavior of newly designed and manufactured precast “I” blocks infilled with fresh and recycled aggregates. A series of tests were performed using a specially designed & fabricated direct shear apparatus to assess the frictional behavior of infilled blocks under different normal loading conditions. The tests were executed based on the exiting ASTM and National Concrete Masonry Association (NCMA) test protocols. Test results were outlined in the form of shear stress-displacement relationship to compare the effect of recycled aggregate against the fresh aggregate. Shear capacity envelopes were also plotted using Mohr-Coulomb failure criteria to find out the angle of friction for each case. Test results revealed that the angle of friction of the blocks infilled with the recycled aggregate is almost equal to those with the fresh aggregate.","PeriodicalId":358440,"journal":{"name":"2011 IEEE Symposium on Business, Engineering and Industrial Applications (ISBEIA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131227605","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}
