For some arrhythmias that can cause sudden cardiac arrest, the patient needs to be sent to the hospital for immediate treatment. Most of the current electrocardiogram (ECG) devices are bulky, cost expensive, and does not include the self-classification or interpretation ability. Hence it is not suitable for small clinics and patients to use as the first screening devices. This paper proposed a SoC-based implementation of arrhythmia detector by using embedded software design. It able to analyze the heart rate variability (HRV), diagnose and classify the arrhythmias in terms of ventricular fibrillation (VF), premature ventricular contraction (PVC), and two degree heart block (2o Block) base on the R-R interval properties. The ECG signal is pre-processed and extract the R peak using Pan and Tompkins algorithm. The arrhythmia can be detected based on knowledge-based classification of the R-R intervals. The proposed system is prototyped on the Altera Video and Embedded Evaluation Kit with Multi-Touch (VEEK-MT) FPGA development board. Results shows that the proposed system able to classify the aforementioned arrhythmia types with convincing average detection accuracy in range of 85.71% to 93.61% based on MIT-BIH database.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"61 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129532284","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}

However, most previous approaches do not lead to good results. If the density of noise increases rapidly, the quality of the image tremendously decreases and the restoration of those images is a difficult task. This paper proposes an optimal method to suppress the noise with high density properly based on a nonlinear filter and decision-based approach. We assume a 3×3 fix window to scan the image from top-left to bottom-right of the image pixel by pixel. This size of window guarantees the image saving with more details and avoiding the image blurring. There are two steps, detection of the corrupted pixels and then restoration. Detection is provided by using statistical analysis in each window, then the appropriate replacement for the noisy pixel is conducted from given values inside the current window or adjacent reconstructed pixels based on mean calculation and also, for very high density of noise which density of noise is bigger than %80, the reconstruction is based on a recursive approach. Experimental results on some benchmark images and video clips show that this method is a successful algorithm for suppression of salt and pepper noise with high density; besides, they show that the computational complexity and time consuming are reasonable.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128428171","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}

By reducing the power consumption of a particular system, we could effectively prolong the runtime of the system, allowing for longer operational condition of a particular system. Previous studies have suggested that the power characteristics of a modern embedded processor have since been improved with manufacturer's implementation of better energy-focused designs. Implementation of hardware optimization such as better clock and power gating have been shown to produce better energy usage during on-load and off-load processing. In this paper we benchmarked the energy use of a modern embedded processor and study the effects of idling time to the processor and system energy usage. We have found that the processor energy use is significantly reduced in the instant that the processor goes idle during the execution process. The idling time during a processing timeslice allows the processor to use significantly less energy without explicitly depending on a frequency scaling algorithm to reduce energy consumption. This power saving feature directly implemented inside the processor hardware have the possibility to render software based frequency scaling algorithm and DVFS method to be less effective in reducing energy usage.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124116329","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}

We propose an analytical model to calculate gate capacitance and drain current of gate-all-around (GAA) nanowire MOSFET, a prospective device to replace the state-of-art FinFET in near future as per ITRS roadmap. The gate capacitance in strong inversion region is modeled incorporating quantum mechanical effects which are verified against the results obtained from self-consistent simulation of Schrödinger-Poisson equation appeared in recent literature. This model can also be extended for calculating gate capacitance in strong inversion region of different Multi-gate MOSFETs. A Spice compatible analytic model for drain current is also proposed which shows excellent agreement with the reported results of experimentally demonstrated In0.53Ga0.47As (2×1016/cm3) GAA MOSFET. Using the proposed formula for gate capacitance in strong inversion region and drain current together with semi-numerical ballistic MOSFET model, the performance of In0.53Ga0.47As (2×1016/cm3) GAA MOSFET is examined. This device is found suitable for ultra-high performance application with very high intrinsic cut-off frequency resulting from very low gate delay and very high on current and gate capacitance. The proposed analytical model of gate capacitance utilizes a modified form of co-axial cable capacitance along with the quantum capacitance limit to form a computationally efficient formula that is in well agreement with the results appeared in recent literature. On the other hand, Landauer-Buttiker formula and compact model for drain current of planar bulk-MOSFET are utilized to form the model for analytic drain current that shows excellent agreement with the experimental results appeared in the literature in recent past. The proposed model can be used for Spice modeling and circuit simulation of In0.53Ga0.47As GAA MOSFET. Moreover, this model is flexible and can be modified for other high performance multi-gate nano-devices.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134147651","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}

Color is an important quality attribute that affects consumer acceptance and preference in the food industry. Human perception of color has been used as an indirect measure for classifying fruits in indices as fruits matured and ripened. This study was conducted to measure fruit quality by using visible optical fiber sensors that contains of RGB LEDs which are red, green and blue with peak wavelengths at 635 nm, 525 nm, and 470 nm, respectively. Moreover, this study aims to provide an innovative and low-cost approach for nondestructive fruit quality measurement. Multiple linear regressions was applied to develop calibration models for classifying fruits based on the index. Results showed that the proposed optical instruments can produce good and accurate measurements when evaluating the index. The highest coefficient of determination (R2 = 0.879), was obtained by using a combination of red, green, and blue data sets at various ripeness indices. Meanwhile, the optical fiber of red system generated by the monochromatic wavelength exhibited better precision (R2 = 0.795) compared with the other two wavelengths. In conclusion, the application of these systems leads to the rapid and efficient assessment of the quality measurement of mangoes.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133424843","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}
