Chua","doi":"10.1109/ICST46873.2019.9047713","DOIUrl":"https://doi.org/10.1109/ICST46873.2019.9047713","url":null,"abstract":"Conventional imaging sensors often reach their limits in terms of resolution and dynamic range. In addition, conventional imaging in invisible wavelengths is relatively more expensive and complicated. As an alternative, single-pixel cameras allow reduction of cost and complexity that would be otherwise required in a conventional multi-nixel camera. In terms of digital imaging, Nyquist-Shannon theorem states that to stably recover an image without introducing perceptible errors, the number of measurements and the number of image pixels are required to be at least the same. As the number of image pixels is ever increasing, increasing the number of measurements to fulfill Nyquist-Shannon theorem's requirements has become increasingly challenging. Since in many cases increasing the number of measurements means that the cost and time required are increasing accordingly as well. Therefore a mean to recover images from a number of measurements less than the number of pixels (sub-Nyquist measurements) is needed. The objective of this paper is to present and compare single-pixel imaging via compressive sensing/sampling (CS) and spatially-variant resolution (SVR) single-pixel imaging. Both methods are capable of recovering images stably from sub-Nyquist measurements. The measurements and reconstructions of images were done in simulations. SVR single-pixel imaging reduces the number of measurement by sacrificing the resolution of the peripheral regions. This realizes the programmable imaging concept where multi-resolution can be adaptively applied to optimize the balance between image quality and number of measurement. This could benefit some imaging applications where a target in the region of interest (the fovea) is prioritized over the rest of the region (such as the background).","PeriodicalId":344937,"journal":{"name":"2019 13th International Conference on Sensing Technology (ICST)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117124175","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}

Given that any problem of these muscles will lead to speaking difficulties, understanding the contraction patterns of the facial and neck muscles is helpful to explore the muscular mechanism of various speaking problems. In this study, the high-density surface electromyography (HD sEMG) technique was proposed to examine the muscular activities associated with speaking. The HD sEMG signals were acquired when the human subjects were speaking English daily words by 120 channels of closely-spaced electrodes, symmetrically placed on the left and right sides of the facial/neck muscles. The results showed that the energy maps calculated from normalized RMS values of the sEMG signals could illustrate the dynamic spatiotemporal properties of the muscle activities during different speaking tasks. There were high left-right symmetric properties for the RMS curves and energy maps, and further analyses of the correlation coefficients confirmed a significant left-right correlation for the facial and neck muscles during the speaking. The findings of this study suggested that the HD sEMG signals would be useful to evaluate the muscle contraction patterns related to speaking activities and could be a potential tool for diagnosing the muscular functions of speaking difficulties.","PeriodicalId":344937,"journal":{"name":"2019 13th International Conference on Sensing Technology (ICST)","volume":"65 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117230954","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 system boosts an input of 500 mV from a photovoltaic cell without using a typical boost converter circuit that employs an inductor element. Hence, a simplified on-chip design charges an external 1.3-V rechargeable battery. The use of a multi-stage differential-drive rectifier eliminates the need for expensive on-chip inductors. A charge control circuit is implemented to maintain the battery voltage and avoid overcharging, thus improving battery life. A low-dropout voltage regulator further regulates the battery voltage to produce a stable dc voltage. The chip core design has a total area of 1342µm×1011µm.

These sensors are embedded in aircrafts and satellites like the Landsat, which has more data freely available but lack the spatial resolution that suborbital sensors have. To increase the spatial resolution, a series of techniques have been developed like pansharpenning data fusion and more advanced convolutional neural networks for super-resolution, however, the later requires large datasets. To overcome this requirement, this work aims to increase the spatial resolution of Landsat spectral bands using artificial neural networks that uses pixel kernels of a single high-resolution image from Google Earth. Using this method, the high-resolution spectral bands were generated with pixel size of 1m in contrast to the 15m of pansharpenned Landsat bands. The evaluate the predicted spectral bands the validation measures Universal Quality Index (UQI) and Spectral Angle Mapper (SAM) were used, showing values of 0.98 and 0.16 respectively, presenting good results.","PeriodicalId":344937,"journal":{"name":"2019 13th International Conference on Sensing Technology (ICST)","volume":"347 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126679811","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}

For most of the cases, spatiotemporal data is crucial for the information acquired by a wearable device, to be meaningful. Received signal strength (RSS) fingerprints based indoor positioning methods have gained intense focus due to their advantages over the other methods. However, RSS-based indoor localization methods are prone to lower accuracies due to the disturbance caused by various factors that affect the signal link quality. Proper knowledge and well understanding of RSS behaviors with different factors can assist in achieving higher accuracy in position estimation. Nevertheless, most of the existing studies overlooked this important aspect. This study demonstrates the effects of several parameters like antenna polarization, sensor placement height, device diversity and presence of the human body on signal RSS value from positioning point of view with wearables. Experiments are conducted using IEEE 802.15.4 based 2.4 GHz radio modules. Analysis of collected data shows that the considered parameters have significant impacts on RSSI that should be taken into account to improve positioning accuracy.","PeriodicalId":344937,"journal":{"name":"2019 13th International Conference on Sensing Technology (ICST)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121400388","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}

Significant advances in modern healthcare technologies, medicines and overall health care awareness gave many to lead a prolonged healthy life. Over the past few years, there has been a huge demand for unobtrusive health monitoring systems from both medical professionals and the general populace to use these technologies for understanding the general health well being in order to improve life longevity. However, most of the available technologies for health monitoring are difficult for the general populace to access and most of the developed health monitoring systems are either deployed in a controlled environment or in healthcare facilities, thus severely limiting the ease of access to many, especially the elderly people. For effective health management of elderly people, evidence-based decision making, continuously monitoring the health status of the elderly demographic is paramount. In order to address these issues, we developed an innovative smart IoT based outdoor health monitoring system. The proposed system collects information about the mobility, posture, and overall gait of the person in an easy to access public outdoor setting such as parks, supermarkets etc. It is quite evident from multiple studies, that analysing the gait can be a useful tool in early detection of the declining health of individuals, as mobility is a key factor in any individual's well being. Also, detecting gait disorders earlier will allow for functional relief to the health care system with the possibility of reducing the number and severity of gait disorders through early intervention.","PeriodicalId":344937,"journal":{"name":"2019 13th International Conference on Sensing Technology (ICST)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121200349","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}
