Internet of Things for Sustainable Human Health
The sustainable health IoT has the strong potential to bring tremendous improvements in human health and well-being through sensing, and monitoring of health impacts across the whole spectrum of climate change. The sustainable health IoT enables development of a systems approach in the area of human health and ecosystem. It allows integration of broader health sub-areas in a bigger archetype for improving sustainability in health in the realm of social, economic, and environmental sectors. This integration provides a powerful health IoT framework for sustainable health and community goals in the wake of changing climate. In this chapter, a detailed description of climate-related health impacts on human health is provided. The sensing, communications, and monitoring technologies are discussed. The impact of key environmental and human health factors on the development of new IoT technologies also analyzed
A Scale Independent Selection Process for 3D Object Recognition in Cluttered Scenes
During the last years a wide range of algorithms
and devices have been made available to easily acquire range
images. The increasing abundance of depth data boosts
the need for reliable and unsupervised analysis techniques,
spanning from part registration to automated segmentation.
In this context, we focus on the recognition of known objects
in cluttered and incomplete 3D scans. Locating and fitting a
model to a scene are very important tasks in many scenarios
such as industrial inspection, scene understanding, medical
imaging and even gaming. For this reason, these problems
have been addressed extensively in the literature. Several
of the proposed methods adopt local descriptor-based
approaches, while a number of hurdles still hinder the use
of global techniques. In this paper we offer a different
perspective on the topic: We adopt an evolutionary selection
algorithm that seeks global agreement among surface points,
while operating at a local level. The approach effectively
extends the scope of local descriptors by actively selecting
correspondences that satisfy global consistency constraints,
allowing us to attack a more challenging scenario where
model and scene have different, unknown scales. This leads
to a novel and very effective pipeline for 3D object recognition,
which is validated with an extensive set of experiment

Not AvailableBoron (B) deficiency is a common factor in light-textured soils causing poor pod filling and yield in large seeded peanut. Field trials were conducted in soils having 0.20–0.45 mg kg¡1 available B to find out the effectiveness of commercial-grade B sources in large seeded peanuts. B application induced early flowering, increased pods, yield and yield attributes, shelling and 100- seed weight. Soil application of 2.0 kg B ha¡1 as commercial-grade Agricol, Solubor and Borosol increased these parameters to a similar degree as obtained by borax, but were superior over their foliar applications. Similarly, the responses of foliar applications of 1.0 kg B ha¡1 as Chemiebor, Solubor and Borosol were more effective in humid areas. However, foliar applications
led to scorching of peanut leaves during dry weather. Thus, soil application of 2.0 kg B ha¡1 is essential to enhance productivity and pod filling in large seeded peanut.Not Availabl
Performance evaluation of 3D local feature descriptors
A number of 3D local feature descriptors have been proposed in literature. It is however, unclear which descriptors are more appropriate for a particular application. This paper compares nine popular local descriptors in the context of 3D shape retrieval, 3D object recognition, and 3D modeling. We first evaluate these descriptors on six popular datasets in terms of descriptiveness. We then test their robustness with respect to support radius, Gaussian noise, shot noise, varying mesh resolution, image boundary, and keypoint localization errors. Our extensive tests show that Tri-Spin-Images (TriSI) has the best overall performance across all datasets. Unique Shape Context (USC), Rotational Projection Statistics (RoPS), 3D Shape Context (3DSC), and Signature of Histograms of OrienTations (SHOT) also achieved overall acceptable results
