    This article introduces information gathered through 21 semi-structured interviews conducted with UK, EU and international professionals in the field of General Data Protection Regulation (GDPR) compliance and technology design, with a focus on the smart home context and vulnerable people using smart products. Those discussions gave various insights and perspectives into how the two communities (lawyers and technologists) view intricate practical data protection challenges in this specific setting. The variety of interviewees allowed to compare different approaches to data protection compliance topics. Answers to the following questions were provided: when organisations develop and/or deploy smart devices that use personal data, do they take into consideration the needs of vulnerable groups of people to comply with the GDPR? What are the underlying issues linked to the practical data protection law challenges faced by organisations working on smart devices used by vulnerable persons? How do experts perceive data protection law-related problems in this context?

    The Billund delta: a possible new giant aquifer in central and western Jutland

    The search for new, deep-seated drinking water resources in Denmark has increased significantly during the past five years as a result of the discovery of excessive amounts of nitrate, pesticides and other pollutants in shallow groundwater boreholes (e.g. Nygaard et al. 2004, this volume). To find and map these aquifers, a multidisciplinary sequence stratigraphic approach has successfully been applied to the Miocene deposits of southern Jutland, where especially the Odderup and Ribe Formations are known as a main aquifer for drinking water from several test wells (Rasmussen et al. 2002). Recently, a more systematic study of the Miocene succession in central and western Jutland has been initiated by the Geological Survey of Denmark and Greenland (GEUS) under contract with local authorities. It includes detailed sedimentological descriptions of outcrops, sedimentological and log-interpretations of new stratigraphic boreholes and interpretation of new high-resolution seismic data (Fig. 1). A number of outcrops and wells have been studied palynologically, resulting in a detailed dinoflagellate cyst stratigraphy and in palynofacies interpretations. The results of these studies have been integrated in the regional geological and stratigraphic model (Fig. 2). Two new aquifers have been discovered: the Bastrup sand and the Billund sand. The Bastrup sand has already been exploited as a main aquifer in central and southern Jutland, and has been referred to either the Ribe or Odderup Formations. However, new stratigraphic results reveal that the Bastrup sand is a separate unit in the Miocene succession. The Billund sand is a deep-seated aquifer located more than 100 m and often more than 150 m deep, and is therefore not penetrated by standard water supply wells which rarely reach c. 100 m. The Billund sand was first revealed by multichannel seismic data deriving from former oil-exploration carried out in the Billund area (Fig. 3A). The resolution of these seismic data is very poor, but one interpretation of the dipping reflectors (clinoforms) seen in Fig. 3A was of a delta complex. This agrees with outcrop studies along the fjords of eastern Jutland which suggest that a spit complex was deposited in this area during the Early Miocene. The Billund sand was tested by the Vandel Mark well in 2001, which penetrated c. 40 m of sand at a depth of 200 m. The presence of a regional major sand body was later confirmed by new high-resolution seismic data and by the Billund and Løvlund wells in 2002. The Billund well penetrated 50 m of medium- to coarse-grained sand, and chemical tests of the water quality were good. However, a water supply well at Fjand in western Jutland has had problems with so-called ‘brown water’ – water enriched in organic matter (humus). Saline water may also be expected close to older deep-seated faults. This paper summarises the results of a mapping programme of the Billund sand initiated in the summer of 2003

    A Mountain as Multiverse: Circumnavigating the Realities and Meta-Realities of a Kailas Pilgrim.

    Get PDF
    This article explores the mountain as a site of pilgrimage. It considers the efficacy of pain and peril in bringing value to the 'sacred' point of arrival in the contexts of pilgrimage, expedition and objective exploration, focussing on the contextual history and contemporary experience of walks around Mount Kailash in Tibet, referring back to the other examples to form a comparative argument around the broader issues of relativity connecting the embodied to the spiritually realised. There are facts here, imaginings, reconstructions and subjectivity but these find consolidation in three foci: 1. The peaceful and unanimous appropriation of a single sacred space by multiple religions; 2. The ritual liminoid efficacy of a pilgrimage in a genuinely perilous environment; 3. The intertextuality of the symbolic space and the real space as they are performed within the unique natural mandala of Mount Kailas in Tibet. Kailash is the spiritual centre of the universe in Tibetan Buddhism, the home of Siva in Hinduism and is also a holy site in Bonism; it is therefore a multi-faith site with multiple symbolic existences operative at once. However, it was also once perceived to be the possible source of great rivers such as the Ganges and as such is bound up with colonial tales of secret and disguised Victorian expeditions to survey and map, usually ending in great peril. Pilgrims and expeditionaries walk around the mountain - indeed it is claimed to be a pilgrimage route to a 5th of the world's population - in a circumnavigation that takes them to some 18600 feet in the outer kora, higher on the inner, and as such the 'walk' claims lives annually. The article draws upon experiences of the walk, both secular and non-secular, both physical and meta-physical, exploring written accounts from the multiple perspectives of authors such as Krishna Yadav, Colin Thubron, Shri Swami Satchinanada, Gibbons & Pritchard-Jones, John Snelling, Charles Allen. The article concludes with a consideration of the higher space and a state of liminal realisation gained only when something is risked through the traversing of that space, discussing the crucial and causal link that connects exposure to self-endangerment, the charging of a sacred venue and the attainments realised

    Exact Solution of Two-Species Ballistic Annihilation with General Pair-Reaction Probability

    Full text link
    The reaction process A+B>CA+B->C is modelled for ballistic reactants on an infinite line with particle velocities vA=cv_A=c and vB=cv_B=-c and initially segregated conditions, i.e. all A particles to the left and all B particles to the right of the origin. Previous, models of ballistic annihilation have particles that always react on contact, i.e. pair-reaction probability p=1p=1. The evolution of such systems are wholly determined by the initial distribution of particles and therefore do not have a stochastic dynamics. However, in this paper the generalisation is made to p<1p<1, allowing particles to pass through each other without necessarily reacting. In this way, the A and B particle domains overlap to form a fluctuating, finite-sized reaction zone where the product C is created. Fluctuations are also included in the currents of A and B particles entering the overlap region, thereby inducing a stochastic motion of the reaction zone as a whole. These two types of fluctuations, in the reactions and particle currents, are characterised by the `intrinsic reaction rate', seen in a single system, and the `extrinsic reaction rate', seen in an average over many systems. The intrinsic and extrinsic behaviours are examined and compared to the case of isotropically diffusing reactants.Comment: 22 pages, 2 figures, typos correcte

    Use of a Closed-Loop Tracking Algorithm for Orientation Bias Determination of an S-Band Ground Station

    The Space Communications and Navigation (SCaN) Testbed project completed installation and checkout testing of a new S-Band ground station at the NASA Glenn Research Center in Cleveland, Ohio in 2015. As with all ground stations, a key alignment process must be conducted to obtain offset angles in azimuth (AZ) and elevation (EL). In telescopes with AZ-EL gimbals, this is normally done with a two-star alignment process, where telescope-based pointing vectors are derived from catalogued locations with the AZ-EL bias angles derived from the pointing vector difference. For an antenna, the process is complicated without an optical asset. For the present study, the solution was to utilize the gimbal control algorithms closed-loop tracking capability to acquire the peak received power signal automatically from two distinct NASA Tracking and Data Relay Satellite (TDRS) spacecraft, without a human making the pointing adjustments. Briefly, the TDRS satellite acts as a simulated optical source and the alignment process proceeds exactly the same way as a one-star alignment. The data reduction process, which will be discussed in the paper, results in two bias angles which are retained for future pointing determination. Finally, the paper compares the test results and provides lessons learned from the activity

    Some geometrical methods for constructing contradiction measures on Atanassov's intuitionistic fuzzy sets

    Trillas et al. (1999, Soft computing, 3 (4), 197–199) and Trillas and Cubillo (1999, On non-contradictory input/output couples in Zadeh's CRI proceeding, 28–32) introduced the study of contradiction in the framework of fuzzy logic because of the significance of avoiding contradictory outputs in inference processes. Later, the study of contradiction in the framework of Atanassov's intuitionistic fuzzy sets (A-IFSs) was initiated by Cubillo and Castiñeira (2004, Contradiction in intuitionistic fuzzy sets proceeding, 2180–2186). The axiomatic definition of contradiction measure was stated in Castiñeira and Cubillo (2009, International journal of intelligent systems, 24, 863–888). Likewise, the concept of continuity of these measures was formalized through several axioms. To be precise, they defined continuity when the sets ‘are increasing’, denominated continuity from below, and continuity when the sets ‘are decreasing’, or continuity from above. The aim of this paper is to provide some geometrical construction methods for obtaining contradiction measures in the framework of A-IFSs and to study what continuity properties these measures satisfy. Furthermore, we show the geometrical interpretations motivating the measures

    • The number of smart home devices is increasing. They are used by vulnerable people regardless of whether they are designed specifically for them or for the general population (eg, smart door locks, smart alarms, or voice assistants). • This article focuses on children and inherently vulnerable adults, and analyses how to comply with the General Data Protection Regulation (GDPR) when the latter use smart products, with a particular focus on the UK through references made to the Information Commissioner’s Office guidelines and reports. • Complying with the GDPR provisions related to the processing of vulnerable people’s data would be beneficial not only for the latter but also for organizations developing and deploying smart devices. • This article argues in favour of protecting vulnerable people’s data by design and default in every smart product. • The objective of this work is also to draw attention to the need of thinking about vulnerability across all data protection principles and to propose solutions on how to effectively comply with the GDPR in this context

    Exact solution of the one-dimensional ballistic aggregation

    Full text link
    An exact expression for the mass distribution ρ(M,t)\rho(M,t) of the ballistic aggregation model in one dimension is derived in the long time regime. It is shown that it obeys scaling ρ(M,t)=t4/3F(M/t2/3)\rho(M,t)=t^{-4/3}F(M/t^{2/3}) with a scaling function F(z)z1/2F(z)\sim z^{-1/2} for z1z\ll 1 and F(z)exp(z3/12)F(z)\sim \exp(-z^3/12) for z1z\gg 1. Relevance of these results to Burgers turbulence is discussed.Comment: 11 pages, 2 Postscript figure
