    Fluent and confident speech is desirable to every speaker. But professional speech delivering requires a great deal of experience and practice. In this paper, we propose a speech stream manipulation system which can help non-professional speakers to produce fluent, professional-like speech content, in turn contributing towards better listener engagement and comprehension. We propose to achieve this task by manipulating the disfluencies in human speech, like the sounds 'uh' and 'um', the filler words and awkward long silences. Given any unrehearsed speech we segment and silence the filled pauses and doctor the duration of imposed silence as well as other long pauses ('disfluent') by a predictive model learned using professional speech dataset. Finally, we output a audio stream in which speaker sounds more fluent, confident and practiced compared to the original speech he/she recorded. According to our quantitative evaluation, we significantly increase the fluency of speech by reducing rate of pauses and fillers

    In this paper, we design algorithms for indoor activity recognition and 3D thermal model generation using thermal images, RGB images, captured from external sensors, and the internet of things setup. Indoor activity recognition deals with two sub-problems: Human activity and household activity recognition. Household activity recognition includes the recognition of electrical appliances and their heat radiation with the help of thermal images. A FLIR ONE PRO camera is used to capture RGB-thermal image pairs for a scene. Duration and pattern of activities are also determined using an iterative algorithm, to explore kitchen safety situations. For more accurate monitoring of hazardous events such as stove gas leakage, a 3D reconstruction approach is proposed to determine the temperature of all points in the 3D space of a scene. The 3D thermal model is obtained using the stereo RGB and thermal images for a particular scene. Accurate results are observed for activity detection, and a significant improvement in the temperature estimation is recorded in the 3D thermal model compared to the 2D thermal image. Results from this research can find applications in home automation, heat automation in smart homes, and energy management in residential spaces

    This work includes wifi signal strength survey of 'VIT Campus' wifi network. After analysing the AP's throughout the college, the wifi signal strength on each floor of each building was recorded using "wifi analyser" app. The recorded readings were mapped and discrepancies and redundancies in the placements of AP's was studied considering the facts such as student densities, obstacles, laboratories, classrooms. Dead zones were identified and the AP's were optimised and additional AP's are suggested to have a more effective coverage

    Background: A key component of achieving universal health coverage is ensuring that all populations have access to quality health care. Examining where gains have occurred or progress has faltered across and within countries is crucial to guiding decisions and strategies for future improvement. We used the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) to assess personal health-care access and quality with the Healthcare Access and Quality (HAQ) Index for 195 countries and territories, as well as subnational locations in seven countries, from 1990 to 2016. Methods Drawing from established methods and updated estimates from GBD 2016, we used 32 causes from which death should not occur in the presence of effective care to approximate personal health-care access and quality by location and over time. To better isolate potential effects of personal health-care access and quality from underlying risk factor patterns, we risk-standardised cause-specific deaths due to non-cancers by location-year, replacing the local joint exposure of environmental and behavioural risks with the global level of exposure. Supported by the expansion of cancer registry data in GBD 2016, we used mortality-to-incidence ratios for cancers instead of risk-standardised death rates to provide a stronger signal of the effects of personal health care and access on cancer survival. We transformed each cause to a scale of 0-100, with 0 as the first percentile (worst) observed between 1990 and 2016, and 100 as the 99th percentile (best); we set these thresholds at the country level, and then applied them to subnational locations. We applied a principal components analysis to construct the HAQ Index using all scaled cause values, providing an overall score of 0-100 of personal health-care access and quality by location over time. We then compared HAQ Index levels and trends by quintiles on the Socio-demographic Index (SDI), a summary measure of overall development. As derived from the broader GBD study and other data sources, we examined relationships between national HAQ Index scores and potential correlates of performance, such as total health spending per capita. Findings In 2016, HAQ Index performance spanned from a high of 97\ub71 (95% UI 95\ub78-98\ub71) in Iceland, followed by 96\ub76 (94\ub79-97\ub79) in Norway and 96\ub71 (94\ub75-97\ub73) in the Netherlands, to values as low as 18\ub76 (13\ub71-24\ub74) in the Central African Republic, 19\ub70 (14\ub73-23\ub77) in Somalia, and 23\ub74 (20\ub72-26\ub78) in Guinea-Bissau. The pace of progress achieved between 1990 and 2016 varied, with markedly faster improvements occurring between 2000 and 2016 for many countries in sub-Saharan Africa and southeast Asia, whereas several countries in Latin America and elsewhere saw progress stagnate after experiencing considerable advances in the HAQ Index between 1990 and 2000. Striking subnational disparities emerged in personal health-care access and quality, with China and India having particularly large gaps between locations with the highest and lowest scores in 2016. In China, performance ranged from 91\ub75 (89\ub71-93\ub76) in Beijing to 48\ub70 (43\ub74-53\ub72) in Tibet (a 43\ub75-point difference), while India saw a 30\ub78-point disparity, from 64\ub78 (59\ub76-68\ub78) in Goa to 34\ub70 (30\ub73-38\ub71) in Assam. Japan recorded the smallest range in subnational HAQ performance in 2016 (a 4\ub78-point difference), whereas differences between subnational locations with the highest and lowest HAQ Index values were more than two times as high for the USA and three times as high for England. State-level gaps in the HAQ Index in Mexico somewhat narrowed from 1990 to 2016 (from a 20\ub79-point to 17\ub70-point difference), whereas in Brazil, disparities slightly increased across states during this time (a 17\ub72-point to 20\ub74-point difference). Performance on the HAQ Index showed strong linkages to overall development, with high and high-middle SDI countries generally having higher scores and faster gains for non-communicable diseases. Nonetheless, countries across the development spectrum saw substantial gains in some key health service areas from 2000 to 2016, most notably vaccine-preventable diseases. Overall, national performance on the HAQ Index was positively associated with higher levels of total health spending per capita, as well as health systems inputs, but these relationships were quite heterogeneous, particularly among low-to-middle SDI countries. Interpretation GBD 2016 provides a more detailed understanding of past success and current challenges in improving personal health-care access and quality worldwide. Despite substantial gains since 2000, many low-SDI and middle- SDI countries face considerable challenges unless heightened policy action and investments focus on advancing access to and quality of health care across key health services, especially non-communicable diseases. Stagnating or minimal improvements experienced by several low-middle to high-middle SDI countries could reflect the complexities of re-orienting both primary and secondary health-care services beyond the more limited foci of the Millennium Development Goals. Alongside initiatives to strengthen public health programmes, the pursuit of universal health coverage hinges upon improving both access and quality worldwide, and thus requires adopting a more comprehensive view-and subsequent provision-of quality health care for all populations

    End of Life Vehicles (ELVs) can act as a source of secondary raw materials at the same time can pose a severe threat to our ecosystem if the ELVs are handled unscientifically. Globally, abundant research is being carried out on obsolete vehicles to harness energy and to reduce negative impacts on the environment. India, characterized by an informal ELV handling sector has achieved material recovery and recycling efficiency up to some extent but lacks in the incorporation of eco-friendly management of ELVs, and this issue needs to be addressed along with the problems of social and economic sustainability of the firm. The research work is intended to study the prevailing status of ELV handling in India. The current situation is represented by comparing ELV handling capacities of various firms and future ELVs. Also, an assessment of shared responsibility of critical stakeholders is depicted using a radar chart, and relative importance of their involvement is represented. Research also presents a comparative study of ELV legislative policies of different countries. Linear regression is applied to predict the values of ELVs in major Indian cities. Suitable methodologies are employed to collect the required data, and the findings are discussed using illustrative graphs and tables

    No full text
    We integrate the first vapor phase self-assembled monolayer (VPSAM) of hydroxy-phenyl zinc porphyrin (ZnTPPOH) on the interlayer dielectric materials and investigate its properties as a copper diffusion barrier. The ZnTPPOH VPSAMs show a 1.5× improvement over the earlier investigated 3-aminopropyltrimethoxysilane self-assembled monolayers (SAMs) in bias temperature stress (BTS) studies. We show that with the porphyrin SAMs, one can achieve an improvement in breakdown field of a low-K dielectric by two times and a drop in copper diffusion by six times as measured by secondary ion mass spectroscopy

    Pentacene-based Organic Field Effect Transistors (OFETs) are promising platforms for sensing and computing applications. However, due to the chemical reactivity of the organic semiconductor, electrodes cannot be lithographically patterned after the semiconductor is deposited. Deposition of electrodes before the semiconductor material, on the other hand leads to an interface degradation that impacts performance of the organic transistor. In this work, we show for the first time application of porphyrin self-assembled monolayers (SAMs) for work function tuning of metal source/drain electrodes for organic transistor applications. We report the effect of various metal complexed porphyrin SAMs on the surface energy of the electrode and morphology of organic semiconductor and investigate the physical properties as well as electrical characteristics of OFETs with these SAMs

    The usage of natural fiber–reinforced composites (NFRCs) may help the global fraternity in achieving their long-term goal of developing sustainable products having minimum effect on ecosystem, during and at the end of their service life. The primary manufacturing processes such as injection molding, hand-layup, and compression moulding have been extensively used to fabricate products with simpler profiles. However, the fabrication of complex products necessitates secondary manufacturing processes. In current investigation, the short fiber (banana and bagasse)–based polypropylene composites (10, 15, and 20 wt.%) were fabricated using extrusion-injection moulding process. Banana fiber–based composites recorded 1.8%, 4.7%, and 3.25%, higher tensile strength than bagasse fiber–based composites at 10, 15, and 20 wt.% fiber loading, respectively. However, bagasse fiber–based composites performed distinctly better in flexural properties. Field emission scanning electron microscopy and thermogravimetric analysis were employed to analyze the failure mechanisms and thermal degradation behavior (analyzed at 5%, 25%, 50%, and 75% weight loss) of the fabricated composites. The ultrasonic welded joints of banana fiber–based composites recorded higher failure load prior to the fracture as compared to bagasse fiber–based composites upto 15% fiber loading. It was established that ultrasonic welding can be successfully employed for joining of NFRCs
