Computer Science - Computer Vision and Pattern Recognition ,Computer Science - Artificial Intelligence ,Computer Science - Performance - Abstract
Computer vision has achieved impressive progress in recent years. Meanwhile, mobile phones have become the primary computing platforms for millions of people. In addition to mobile phones, many autonomous systems rely on visual data for making decisions and some of these systems have limited energy (such as unmanned aerial vehicles also called drones and mobile robots). These systems rely on batteries and energy efficiency is critical. This article serves two main purposes: (1) Examine the state-of-the-art for low-power solutions to detect objects in images. Since 2015, the IEEE Annual International Low-Power Image Recognition Challenge (LPIRC) has been held to identify the most energy-efficient computer vision solutions. This article summarizes 2018 winners' solutions. (2) Suggest directions for research as well as opportunities for low-power computer vision., Comment: Preprint, Accepted by IEEE Journal on Emerging and Selected Topics in Circuits and Systems. arXiv admin note: substantial text overlap with arXiv:1810.01732

Computer Science - Computer Vision and Pattern Recognition - Abstract
The Low-Power Image Recognition Challenge (LPIRC, https://rebootingcomputing.ieee.org/lpirc) is an annual competition started in 2015. The competition identifies the best technologies that can classify and detect objects in images efficiently (short execution time and low energy consumption) and accurately (high precision). Over the four years, the winners' scores have improved more than 24 times. As computer vision is widely used in many battery-powered systems (such as drones and mobile phones), the need for low-power computer vision will become increasingly important. This paper summarizes LPIRC 2018 by describing the three different tracks and the winners' solutions., Comment: 13 pages, workshop in 2018 CVPR, competition, low-power, image recognition

Kolguev Island (69[degrees]05' N 49[degrees]15' E) is located in the Pechora Sea, the southeastern part of the Barents Sea. The island's ecosystem is unusual due to the total absence of rodents and specialized predators such as weasels, while non-specialized predators such as Arctic (Vulpes lagopus) and red (V. vulpes) foxes and Rough-legged Hawk (Buteo lagopus) are common. Currently, 111 bird species have been registered here, of which 58 are nesting. The absence of rodents and the relatively stable predation pressure have resulted in the high abundance of many bird species: Willow Ptarmigan (Lagopus lagopus), several goose species, some waders, and passerines. Over the 125-year history of ornithological studies on Kolguev, the island avifauna has changed significantly. The trend of an increase in the proportion of widespread and Siberian species together with a decrease in the proportion of Arctic species was observed. Since 2006, a thorough monitoring of Kolguev avifauna has been carried out, during which the dynamics of the bird population densities have been traced. The abundance of Black-bellied Plover (Pluvialis squatarola) and Dunlin (Calidris alpina) decreased, while the numbers of Barnacle Goose (Branta leucopsis) have increased sharply since the 1980s. The breeding density of Rough-legged Hawk has also increased in recent years. The long-term monitoring of Kolguev ecosystems has indicated the high international conservation value of the island due to the high breeding density of many bird species. Our study, covering more than a century of avifaunal studies with almost annual monitoring over the past three decades, provides an unusually long and detailed time-series for an Arctic island. Key words: Russian Arctic; Arctic birds; Kolguev Island; population density; population trends; long-term Arctic monitoring; Barents Sea; tundra avifauna; waders; geese L'ile de Kolgouev (69[degrees]05' N 49[degrees]15' E) se situe dans la mer de Pechora, dans la partie sud-est de la mer de Barents. L'ecosysteme de l'ile est inhabituel en raison de l'absence totale de rongeurs et de predateurs specialises comme la belette, tandis que les predateurs non specialises comme le renard arctique (Vulpes lagopus), le renard roux (V. vulpes) et la buse pattue (Buteo lagopus) sont communs. A present, 111 especes d'oiseaux ont ete enregistrees ici, dont 58 y nichent. L'absence de rongeurs et la pression relativement stable exercee par les predateurs ont donne lieu a la grande abondance de nombreuses especes d'oiseaux, soit les lagopedes des saules (Lagopus lagopus), plusieurs especes d'oies, certains echassiers et des passereaux. Au cours de l'histoire des etudes ornithologiques de Kolgouev echelonnee sur 125 ans, la faune aviaire de l'ile a change considerablement. On y observe une tendance vers l'augmentation de la proportion d'especes repandues et d'especes siberiennes, et vers la diminution de la proportion d'especes de l'Arctique. Depuis 2006, la faune aviaire de l'ile de Kolgouev a fait l'objet d'une surveillance rigoureuse, ce qui a permis de tracer la dynamique des densites des populations d'oiseaux. L'abondance de pluviers argentes (Pluvialis squatarola) et de becasseaux variables (Calidris alpina) a diminue, tandis que le nombre de bernaches nonnettes (Branta leucopsis) s'est accru brusquement depuis les annees 1980. Par ailleurs, la densite de reproduction de la buse pattue a augmente ces dernieres annees. La surveillance a long terme des ecosystemes de Kolgouev temoigne de la forte valeur de conservation de cette ile a l'echelle internationale en raison de la densite de reproduction de nombreuses especes d'oiseaux. Notre etude, qui porte sur plus d'un siecle d'etudes de la faune aviaire ayant fait l'objet de travaux de surveillance quasi annuels au cours des trois decennies, fournit une serie chronologique inhabituellement longue et detaillee pour une ile de l'Arctique. Mots cles : Arctique russe; oiseaux de l'Arctique; ile de Kolgouev; densites des populations; tendances des populations; surveillance de l'Arctique a long terme; mer de Barents; faune aviaire de la toundra; echassiers; oies Traduit pour la revue Arctic par Nicole Giguere., Arctic ecosystems are extremely sensitive to anthropogenic pressure and climate changes (Meredith et al., 2019).

- Abstract
The Russian breeding population of barnacle geese Branta leucopsis has shown a rapid increase in numbers since 1980, which has coincided with a southwest-wards breeding range expansion within the Russian Arctic. Here barnacle geese also started to occupy coastal and marsh land habitats, in which they were not know to nest on their traditional breeding grounds. While these changes have been well documented by studies and observations throughout the new breeding range of barnacle geese, observations are lacking from the traditional breeding grounds on Novaya Zemlya, as this area is remote and difficult to access. This is especially relevant given rapid climate warming in this area, which may impact local distribution and population size. We used GPS-tracking and behavioural biologging data from 46 individual barnacle geese captured on their wintering grounds to locate nest sites in the Russian Arctic and study nesting distribution in 2008–2010 and 2018–2020. Extrapolating from nest counts on Kolguev Island, we estimate the breeding population on Novaya Zemlya in 2018–2020 to range around 75,250 pairs although the confidence interval around this estimate was large. A comparison with the historical size of the barnacle goose population suggests an increase in the breeding population on Novaya Zemlya, corresponding with changes in other areas of the breeding range. Our results show that many barnacle geese on Novaya Zemlya currently nest on lowland tundra on Gusinaya Zemlya Peninsula. This region has been occupied by barnacle geese only since 1990 and appears to be mainly available for nesting in years with early spring. Tracking data are a valuable tool to increase our knowledge of remote locations, but counts of breeding individuals or nests are needed to further corroborate estimates of breeding populations based on tracking data.

Physics teachers can effectively use vectors to render physical problems into mathematical constructs. Vector analysis is then used to solve the problems. Students may find an equation easier to understand when it is presented in graphic form. Vectors are especially useful for solving problems relating to projectile motion and Newton's laws.

- Abstract
Economic development and energy exploration are increasing in the Arctic. Important breeding habitats for many waterbird species, which have previously been relatively undisturbed, are now being subjected to these anthropogenic pressures. The conservation of the habitats and the species they support is a significant challenge for sustainable development. Even if governments and corporates operating in this fragile environment are committed to sustainable development, there is little information available to avoid, mitigate and manage environmental risk and impacts. Taking a risk management perspective, we followed the International Finance Corporations (IFC) Performance Standard 6 (PS6) criteria on Environmental and Social Sustainability and developed an approach to identify "critical habitat", as defined in IFC PS6, for waterbird species breeding in the Arctic. While the range of these waterbirds is roughly known, more accuracy is needed for proper risk assessment. We have therefore gone a step further by modelling suitable habitat within these ranges. Depending on the relevance of the species for IFC PS6 and the level of certainty we separated the classes likely and potential critical habitat. We tested the approach for Russian breeding populations of five Anatidae species (White-fronted Goose Anser albifrons, Lesser White-fronted Goose Anser erythropus, Brent Goose Branta bernicla, Redbreasted Goose Branta ruficollis and Bewick's Swan Cygnus columbianus bewicki). Likely critical habitats were identified through a review of literature and available data for these waterbird species and multi-species congregations. To address the information gap for most of the Russian Arctic a species distribution modelling approach was used. The outputs of this approach were labelled as potential critical habitat, indicating the lower level of certainty than likely critical habitat. Based on existing information the amount of likely critical habitat is estimated to be at least x,x
