Online Multi-Person Tracking by Tracker Hierarchy
2012
Tracking-by-detection is a widely used paradigm for multi-person tracking but is affected by variations in crowd density, obstacles in the scene, varying illumination, human pose variation, scale changes, etc. We propose an improved tracking-by-detection framework for multi-person tracking where the appearance model is formulated as a template ensemble updated online given detections provided by a pedestrian detector. We employ a hierarchy of trackers to select the most effective tracking strategy and an algorithm to adapt the conditions for trackers' initialization and termination. Our formulation is online and does not require calibration information. In experiments with four pedestrian t…
Improved Statistically Based Retrievals via Spatial-Spectral Data Compression for IASI Data
2019
In this paper, we analyze the effect of spatial and spectral compression on the performance of statistically based retrieval. Although the quality of the information is not com- pletely preserved during the coding process, experiments reveal that a certain amount of compression may yield a positive impact on the accuracy of retrievals. We unveil two strategies, both with interesting benefits: either to apply a very high compression, which still maintains the same retrieval performance as that obtained for uncompressed data; or to apply a moderate to high compression, which improves the performance. As a second contribution of this paper, we focus on the origins of these benefits. On the one…

The UN Convention on the Rights of the Child's Role in Litigation Before the Committee of Experts of the African Children's Charter
2020
On the occasion of the 30th anniversary of the UN Convention on the Rights of the Child, this article contributes to a reflection about the Convention's impact on domestic and international case law by investigating its role in, and implications for, litigation before the African Committee of Experts on the Rights and Welfare of the Child. To this end, the analysis starts by tracing the core aspects of the African Charter on the Rights and Welfare of the Child, and by comparing its content to that of the UN Convention. It then investigates the extent to which, in its practice, the African Committee has engaged with (or, indeed, ignored or overlooked) the UN Convention, and critically assess…
Commonalities between ENT Specialists and Oral Medicine Experts: Old HPV Diseases and New Oral HPV-Cancer along the Borders
2021
A human papillomavirus (HPV) infection is globally one of the most common causes of sexually transmitted infections of the mucous membranes (genital, anal and oral). Over the last decade, an increasing number of young patients have been infected due to the changes in sexual habits in the general population. The majority of the lesions are benign; however, substantial scientific evidence has suggested a role for the HPV family in the carcinogenesis of squamous cell carcinoma (SCC). It is proposed that dentists, in addition to ENT specialists, should apply standardized management protocols in order to construct a well-defined pathway in terms of diagnosis, which is based on a PCR diagnostic t…
Channel Gain Cartography via Mixture of Experts
2020
In order to estimate the channel gain (CG) between the locations of an arbitrary transceiver pair across a geographic area of interest, CG maps can be constructed from spatially distributed sensor measurements. Most approaches to build such spectrum maps are location-based, meaning that the input variable to the estimating function is a pair of spatial locations. The performance of such maps depends critically on the ability of the sensors to determine their positions, which may be drastically impaired if the positioning pilot signals are affected by multi-path channels. An alternative location-free approach was recently proposed for spectrum power maps, where the input variable to the maps…
Instrumental calculation, cognitive role-playing, or both?: self-perceptions of Seconded National Experts in the European Commission
2011
This is the authors’ final, accepted and refereed manuscript to the article Most work studying micro-processes of integration – i.e. how agents develop identities and decision-making behaviours within a particular institution – offers explanations based on either instrumental rationality or socialisation. This article proposes a two-dimensional framework that allows analysing under which conditions both logics of social action co-exist. Our empirical analysis employs a unique dataset from a 2011 survey of all 1098 currently active Seconded National Experts (SNEs) in the European Commission. We find that a) instrumental cost-benefit calculation and cognitive role-playing (as semi-reflexive s…
Warm experts for elderly users : who are they and what do they do?
2018
This paper examines “warm experts”—that is, nonprofessional persons who help inexperienced users come to terms with digital devices—and their significance for the use of digital media in everyday life by elderly Swedes. We analyze data from a national survey (N = 1264) and from qualitative, semistructured interviews with 18 elderly Swedes (aged 65+). Our data reveal that the warm expert usually is a closelyrelated person, often a child or grandchild, who is strongly involved in nearly every stage of technology domestication, from appropriation (i.e., identifying the need, buying the item, and installing and adjusting it) to incorporation (i.e., choosing and downloading suitable apps, teachi…
Representative Bureaucracy and the Role of Expertise in Politics
2015
This is an open access journal from Cogitatio http://www.cogitatiopress.com The vast majority of existing studies on bureaucratic representation focus on bureaucracies’ permanent and internal staff. Yet, the rising sophistication of modern democracies and the technocratization of political life are gradually inducing an increased reliance on external experts to assist in the development and implementation of policy decisions. This trend, we argue, raises the need to extend studies of bureaucratic representation to such external and non-permanent experts in governmental affairs. In this article, we take a first step in this direction using seconded national experts (SNEs) in the European Com…
Forensic Inspections in the Time of Covid-19
2021
The global pandemic of COVID-19 has impacted the entire world in ways that were unimaginable months ago. It has changed how professionals work and interact with one another. To ensure the safety of experts and attorneys, also forensic inspection procedures must evolve, while still providing a reliable foundation for an expert testimony, relevant to the task at hand. Traditional field inspections require attendees to be physically present and generally in close proximity. Inspecting artifacts may also require that individual components be serially examined by multiple experts, which increases the risk of transmitting the disease. The authors propose a new approach to forensic inspections aim…
