Seismic is one of the hydrocarbon exploration tools. Significant efforts have been directed, in seismic processing and interpretation, to the development of methods such as spectral decomposition used for tuning hydrocarbon reservoirs and delineating it. In addition, statistical techniques are required to analyze variations in seismic traces. This research work is an alternative technique based on singularity spectrum analysis for detecting and delineating hydrocarbon reservoir. Singularity spectrum captures the singularities occurring in a signal. The technique is applied on synthesized seismograms and three attributes of the singularity spectrum namely width, correlation dimension and alphapeak are determined. Results show that by using these attributes the reservoir fluids are detected and delineated. Singularity spectrum analysis will potentially improve the performance of oil & gas industry by reducing drilling uncertainties, producing accurate geological models of 2D seismic data and for correct production estimates of reservoirs.","PeriodicalId":228083,"journal":{"name":"2007 International Conference on Intelligent and Advanced Systems","volume":"79 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131612928","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}

This has led to intensive research activities worldwide to develop new sensing materials and technologies. With the advancement in nanotechnology, miniaturized sensors with reduced weight, lower power consumption, and low cost can be realized. In order to realize this potential, it is critical to develop reliable growth techniques capable of producing high purity, density and desired properties of the sensing element. This article focuses on the production of good quality sensing elements in the form of nanotubes; carbon nanotubes (CNTs) and titania nanotubes. Both types of CNTs, single-walled (SWCNT) and multiwalled (MWCNT) grown in the form of vertically aligned film on the substrates are believed to have enhanced sensing properties because of their high purity and directionality. Similarly with titania nanotubes, their sensitivity and selectivity towards hydrogen would be greatly increased because of their quality. Based on the changes in the specific properties of these nanotubes, chemical sensors can then be developed.","PeriodicalId":228083,"journal":{"name":"2007 International Conference on Intelligent and Advanced Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130525757","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}

This work incorporates the wavelet transform in the blind deconvolution technique to deal with the inherent non-stationarity present in seismic data and to improve the SNR of seismic data. Time varying nature of seismic data is the result of a depth varying character of seismic source wavelet (where high frequency components of the source wavelet get absorbs due to increasing heat gradient with depth) convolved with the non Gaussian distributed earth reflectivity in presence of additive Gaussian, color Gaussian noise. Seismic signal can thus be considered as a result of multiple subsystems with different constraints based on time-frequency localization convolved with input signal. Techniques based on stationarity assumptions are not effective in modeling the time variance character of source with depth. In this work we apply the discrete wavelet transform (DWT) to decompose the seismic data into different time-frequency signals. Denoising based on soft thresholding is applied to get the shrinkage effect of wavelet coefficients. Combination of blind deconvolution technique mixed with the discrete wavelet transform gives the best result in terms of reducing the noise and improving the resolution of seismic data with time. Denoising based on soft thresholding gives optimal minimum means square value, low convolutional noise and also low maximum distortion value than hard thresholding.","PeriodicalId":228083,"journal":{"name":"2007 International Conference on Intelligent and Advanced Systems","volume":"95 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123365078","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 set of sensors consists of accelerometers and flexure sensors has been setup to capture the movement or gesture of shoulder, elbow, wrist, palm and fingers. This project is based on the need of developing an electronic device that can translate the sign language into speech (sound) in order to enable communication to take place between the mute and deaf community with the common public. Hence, the main objective of this project is to develop a system that can convert the sign language into speech so that deaf people are able to communicate efficiently with normal people. This Human-Computer Interaction system is able to recognize 25 common words signing in Bahasa Isyarat Malaysia (BIM) by using the Hidden Markov Models (HMM) method. Both hands are involved to perform the BIM with all the sensors connect wirelessly to a PC with a Bluetooth module. This project aims to capture the hand gestures which involve multiple axis of movement. Altogether 24 sensors have been setup in different hand locations to capture hand and wrist movement in different directions.","PeriodicalId":228083,"journal":{"name":"2007 International Conference on Intelligent and Advanced Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130815700","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}

There is no cure for psoriasis; however, there are many treatment modalities to help control the disease. To evaluate treatment efficacy, PASI (Psoriasis Area and Severity Index) which is the current gold standard method is used to measure psoriasis severity by evaluating the area, erythema, scaliness and thickness of the plaques. However, the calculation of PASI can be tedious and subjective. There have been many attempts in assessing psoriasis lesion area in order to calculate PASI area score. Segmentation on hue-chroma plane of CIE L*a*b* colour space is found to be effective method to extract psoriasis lesion from normal skin. However, centroids of normal skin and psoriasis lesion in hue-chroma plane must be calculated for each patient (local centroids). In this work, we investigate the possibility of using centroids obtained from three different groups based on their skin colour to avoid calculating centroids for each patient. First, patients were grouped according to their skin colour (fair, brown, and dark). For each group, the centroids of four body regions (head, trunk, arm, and leg) are calculated from normal skin and lesion samples of all patients in the group. The study involves patients from three different ethnic origins having different skin tones. Results of segmentation using global centroids are comparable with segmentation using local centroids.","PeriodicalId":228083,"journal":{"name":"2007 International Conference on Intelligent and Advanced Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132995498","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}
