GUI system for Elders/Patients in Intensive Care

In the old age, few people need special care if they are suffering from specific diseases as they can get stroke while they are in normal life routine. Also patients of any age, who are not able to walk, need to be taken care of personally but for this, either they have to be in hospital or someone like nurse should be with them for better care. This is costly in terms of money and man power. A person is needed for 24x7 care of these people. To help in this aspect we purposes a vision based system which will take input from the patient and will provide information to the specified person, who is currently may not in the patient room. This will reduce the need of man power, also a continuous monitoring would not be needed. The system is using MS Kinect for gesture detection for better accuracy and this system can be installed at home or hospital easily. The system provides GUI for simple usage and gives visual and audio feedback to user. This system work on natural hand interaction and need no training before using and also no need to wear any glove or color strip.Comment: In proceedings of the 4th IEEE International Conference on International Technology Management Conference, Chicago, IL USA, 12-15 June, 201

DISCONTINUOUS RECYCLED CARBON FIBER (rCF) REINFORCED POLYPROPYLENE (PP) COMPOSITES USING CARDING

The use of carbon fiber (CF) composites is growing in non-aerospace markets, such as the automotive and transportation sectors. More than 30% of the CF produced ends up as waste material in landfills at end of life (EOL) from sources such as decommissioned aircraft and industrial components. CF retains its properties over decades and offers significant benefits if recycled and repurposed. Recycled CFs (rCF) are less expensive than virgin fibers, and composites made from rCF have mechanical properties that are acceptable for a variety of non-aerospace applications. In this study, a homogenous mixture of rCF-polypropylene (PP) was achieved using the Resonant Acoustic Mixing (RAM) technique, where water was used as a mixing solvent. The nonwoven composite\u27s mechanical properties and molding conditions are influenced by how well the fibers are aligned. Randomly oriented nonwovens have similar mechanical properties in all directions and can be manufactured using a wet-laid (WL) process, whereas highly aligned nonwoven textiles can be manufactured using carding process. Therefore, nonwoven rCF-PP mats were fabricated using carding and WL techniques to understand the effect of fiber orientation on mechanical properties. In this study we observed that carding machine parameters such as pin length, cylinder width, distance between cylinders have influence on final mechanical properties. The mats were compression molded to obtain consolidated panels. Mechanical, microscopic, and fiber length distribution characterization was performed to determine the properties variation between the two manufacturing techniques. The flexural strength and modulus of carding in the machine (along the fibers) direction (MD) was 22% (from 86.89 ± 5.1 MPa to 105.99 ± 12.42 MPa) and 72% (from 5.14 ± 0.5 GPa to 8.85 ± 1.3 GPa), respectively higher as compared to wet-laid. Further, the tensile strength and modulus of carded composites in MD were 75% (from 35.51 ± 5.1 MPa to 62.10 ± 4.8 MPa) and 110.8% (from 6.58 ± 1.81 GPa to 13.87 ± 1.57 GPa), respectively higher than WL process. This work has broad applications in product development with rCF in many commercial and commodity sectors such as sporting goods, automotive, medical devices, etc

Agro-morphological Diversity of High Altitude Bean Landraces in the Kailash Sacred Landscape of Nepal

Many varieties of bean are widely grown across diverse agro-ecological zones in Nepal. And opportunities exist for improving the crops and enhancing their resilience to various biotic and abiotic stressors. In this context, an experiment was conducted from June to October 2016 in Khar VDC of Darchula district to study the phenotypic traits of nine landraces of bean (Phaseolus vulgaris L.). The bean landraces were planted using randomized complete block design in three sites (Dhamidera, Dallekh and Sundamunda villages), with three replications in each site for their comparative analysis. The study considered the following phenotypic traits: days to emergence, days to 50% flowering, days to 90% pod maturity, number of nodes, pod length, pod width, number of pods, number of seeds per pod and weight and grain yield for 100 seeds. Kruskal-Wallis test showed significant differences in the landraces both within and among locations. KA-17-08-FB and KA-17-04-FB were late  flowering (63 and 65 days respectively) compared to other landraces whereas KA-17-07-FB flowered earliest (within 42 days). In all three sites, three landraces namely KA-17-07-FB, KA-17-04-FB and KA-17-06-FB were found to be relatively more resistant to pest and diseases than other landraces. Eight out of nine landraces in Dhamidera and Dallekh villages and seven out of nine in Sundamunda village produced seeds greater than 1.0 t/ha. Among the nine varieties KA-17-02-FB was the highest yielding variety, with an average yield of 3.8 t/ha. This study is useful for identifying suitable landraces for future promotion based on their maturity, grain yield, diseases resistance and other qualitative and quantitative characteristics

Implementation and evaluation of simultaneous video-electroencephalography and functional magnetic resonance imaging

The objective of this study was to demonstrate that the addition of simultaneous and synchronised video to electroencephalography (EEG)-correlated functional magnetic resonance imaging (fMRI) could increase recorded information without data quality reduction. We investigated the effect of placing EEG, video equipment and their required power supplies inside the scanner room, on EEG, video and MRI data quality, and evaluated video-EEG-fMRI by modelling a hand motor task. Gradient-echo, echo-planner images (EPI) were acquired on a 3-T MRI scanner at variable camera positions in a test object [with and without radiofrequency (RF) excitation], and human subjects. EEG was recorded using a commercial MR-compatible 64-channel cap and amplifiers. Video recording was performed using a two-camera custom-made system with EEG synchronization. An in-house script was used to calculate signal to fluctuation noise ratio (SFNR) from EPI in test object with variable camera positions and in human subjects with and without concurrent video recording. Five subjects were investigated with video-EEG-fMRI while performing hand motor task. The fMRI time series data was analysed using statistical parametric mapping, by building block design general linear models which were paradigm prescribed and video based. Introduction of the cameras did not alter the SFNR significantly, nor did it show any signs of spike noise during RF off conditions. Video and EEG quality also did not show any significant artefact. The Statistical Parametric Mapping{T} maps from video based design revealed additional blood oxygen level-dependent responses in the expected locations for non-compliant subjects compared to the paradigm prescribed design. We conclude that video-EEG-fMRI set up can be implemented without affecting the data quality significantly and may provide valuable information on behaviour to enhance the analysis of fMRI data

Engineering Phonon Polaritons in van der Waals Heterostructures to Enhance In-Plane Optical Anisotropy

Van der Waals heterostructures assembled from layers of 2D materials have attracted considerable interest due to their novel optical and electrical properties. Here we report a scattering-type scanning near field optical microscopy study of hexagonal boron nitride on black phosphorous (h-BN/BP) heterostructures, demonstrating the first direct observation of in-plane anisotropic phonon polariton modes in vdW heterostructures. Strikingly, the measured in-plane optical anisotropy along armchair and zigzag crystal axes exceeds the ratio of refractive indices of BP in the x-y plane. We explain that this enhancement is due to the high confinement of the phonon polaritons in h-BN. We observe a maximum in-plane optical anisotropy of {\alpha}_max=1.25 in the 1405-1440 cm-1 frequency spectrum. These results provide new insights on the behavior of polaritons in vdW heterostructures, and the observed anisotropy enhancement paves the way to novel nanophotonic devices and to a new way to characterize optical anisotropy in thin films

Maintaining regularity and generalization in data using the minimum description length principle and genetic algorithm: case of grammatical inference

In this paper, a genetic algorithm with minimum description length (GAWMDL) is proposed for grammatical inference. The primary challenge of identifying a language of infinite cardinality from a finite set of examples should know when to generalize and specialize the training data. The minimum description length principle that has been incorporated addresses this issue is discussed in this paper. Previously, the e-GRIDS learning model was proposed, which enjoyed the merits of the minimum description length principle, but it is limited to positive examples only. The proposed GAWMDL, which incorporates a traditional genetic algorithm and has a powerful global exploration capability that can exploit an optimum offspring. This is an effective approach to handle a problem which has a large search space such the grammatical inference problem. The computational capability, the genetic algorithm poses is not questionable, but it still suffers from premature convergence mainly arising due to lack of population diversity. The proposed GAWMDL incorporates a bit mask oriented data structure that performs the reproduction operations, creating the mask, then Boolean based procedure is applied to create an offspring in a generative manner. The Boolean based procedure is capable of introducing diversity into the population, hence alleviating premature convergence. The proposed GAWMDL is applied in the context free as well as regular languages of varying complexities. The computational experiments show that the GAWMDL finds an optimal or close-to-optimal grammar. Two fold performance analysis have been performed. First, the GAWMDL has been evaluated against the elite mating pool genetic algorithm which was proposed to introduce diversity and to address premature convergence. GAWMDL is also tested against the improved tabular representation algorithm. In addition, the authors evaluate the performance of the GAWMDL against a genetic algorithm not using the minimum description length principle. Statistical tests demonstrate the superiority of the proposed algorithm. Overall, the proposed GAWMDL algorithm greatly improves the performance in three main aspects: maintains regularity of the data, alleviates premature convergence and is capable in grammatical inference from both positive and negative corpora

Assessing the Influence of Importance Prompt and Box Size on Response to Open-ended Questions in Mixed Mode Surveys: Evidence on Response Rate and Response Quality

To understand the thinking behind respondents’ answers, researchers occasionally use open-ended questions. Getting a quality response to open-ended questions can be challenging but attending to the visual design of the question and using a motivational statement in the question can increase item response and data quality. To understand the use of open-ended questions in surveys further, we designed an experiment testing the effect of an importance statement (present/absent) and box size (large/small) on item response rate and response quality in a mixed-mode (web and mail modes) survey. Data for the study came from a survey of Florida Cooperative Extension Service (FCES) clients. The results showed that item response was improved with the importance prompt, irrespective of box size. The combination of importance statement and larger answer box also resulted in more words. Web responses produced more words than those on paper and words counts were significantly improved with an importance prompt for web responses. Overall, the combination of importance prompt, larger box size and web mode was most important in producing the best item response rate and response quality in our mixed-mode survey
