Conclusions. | (Abstract) Due to digital markets' transparency, algorithmic collusion may occur even if algorithms are designed to maximize profits rather than to conspire. The literature suggests that competition rules may not cover algorithmic collusion, being the latter an example of tacit collusion: by monitoring market conditions, each algorithm unilaterally and rationally decides to maintain supra-competitive prices. Data analytics ease the monitoring and reaction to competitors' behaviours, increasing the number of markets subject to tacit collusion. Yet, intention to conspire seems absent. In this Article, it is submitted that algorithmic collusion is different from tacit collusion and can be tackled under EU competition law. In the traditional scenario, undertakings base their rational decisions on the existing markets conditions. While designing their algorithms to maximize profits, undertakings are contributing to create the conditions allowing "tacit" collusion to occur. Moreover, a quasi-strict liability regime applies to antitrust offences, so that intention and imputability play limited roles. As a consequence, if algorithms programmed to maximize profits end up colluding, a rebuttable presumption of the existence of a concerted practice should apply. The practice should be prohibited unless undertakings can prove that, in the specific case, a concerted practice did not occur or that art. 101(3) TFEU applies. Moreover, competition rules may be enforced even without ascertaining any antitrust infringement. Competitive concerns are enough to adopt commitment decisions. Here, the Commission (or a National Competition Authority) may negotiate with the concerned undertakings technical remedies to prevent algorithmic collusion by intervening on the way the algorithms work.

Synthetic biology is an emerging science that aims to create new biological functions that do not exist in nature, based on the knowledge acquired in life science over the last century. Since the beginning of this century, several projects in synthetic biology have emerged. The complexity of the developed artificial bio-functions is relatively low so that empirical design methods could be used for the design process. Nevertheless, with the increasing complexity of biological circuits, this is no longer the case and a large number of computer aided design softwares have been developed in the past few years. These tools include languages for the behavioral description and the mathematical modelling of biological systems, simulators at different levels of abstraction, libraries of biological devices and circuit design automation algorithms. All of these tools already exist in other fields of engineering sciences, particularly in microelectronics. This is the approach that is put forward in this paper., (© 2017 médecine/sciences – Inserm.)

Aim: Administrative health databases such as the French National Heath Insurance Database - SNIIRAM - are a major tool to answer numerous public health research questions. However the use of such data requires complex and time-consuming data management. Our objective was to develop and make available a tool to optimize cohort constitution within administrative health databases., Methods: We developed a process to extract, transform and load (ETL) data from various heterogeneous sources in a standardized data warehouse. This data warehouse is architected as a star schema corresponding to an i2b2 star schema model. We then evaluated the performance of this ETL using data from a pharmacoepidemiology research project conducted in the SNIIRAM database., Results: The ETL we developed comprises a set of functionalities for creating SAS scripts. Data can be integrated into a standardized data warehouse. As part of the performance assessment of this ETL, we achieved integration of a dataset from the SNIIRAM comprising more than 900 million lines in less than three hours using a desktop computer. This enables patient selection from the standardized data warehouse within seconds of the request., Conclusion: The ETL described in this paper provides a tool which is effective and compatible with all administrative health databases, without requiring complex database servers. This tool should simplify cohort constitution in health databases; the standardization of warehouse data facilitates collaborative work between research teams., (Copyright © 2016 Elsevier Masson SAS.

Niger is a Sahelian country of 1,267,000 km2 and 11 M inhabitants (84% living in rural area). The national seroprevalence of the HIV infection is low (2.08% in urban area and 0. 64% in rural area). Because of limited resources, laboratories and qualified personnel are scarce, so the classical strategy using ELISA methods to diagnose HIV is available only in the capital Niamey. In order to define a strategy suitable to the Nigerian field conditions, we have determined the diagnostic value of five commercialised rapid assays (Génie II, InoCheck, Determine, Capillus and Doublecheck). A panel of plasma, whole blood and dried blood spot from 42 positive and 160 negative control individuals was tested and the sensitivity and specificity of each assay were calculated. The two best algorithms using two tests were selected: a algorithm discriminating HIV1 & 2 combining Determine and Genie II showing an excellent sensitivity and specificity (100%) but with many practical constraints; and a non discriminative algorithm combining Determine and Double-check less specific but workable on capillary blood and fully compatible with the field conditions. Its negative predictive value was 100% and its positive predictive value was > 97% for urban population and > 91% for rural population. Dried blood spots on filter paper proved to be very practical and efficient to use by the reference laboratory for the quality control of the peripheral diagnostic centres.

This paper presents an augmented Ant Colony Optimization (ACO) algorithm which we use to solve a single-machine scheduling problem found in an aluminum casting plant. The orders in this scheduling problem have sequence dependent setup times and three distinct objectives must be minimized. We show how the use of multiple visibility matrices contributes to the improvement of solution quality for this multi-objective problem. [ABSTRACT FROM AUTHOR]

The rapidly growing academic and public attention to algorithmic-selection applications such as search engines and social media is indicative of their alleged great social relevance and impact on daily life in digital societies. To substantiate these claims, this paper investigates the hitherto little explored subjective relevance that Internet users assign to algorithmic-selection applications in everyday life. A representative online survey of Internet users comparatively reveals the relevance that users ascribe to algorithmic-selection applications and to their online and offline alternatives in five selected life domains: political and social orientation, entertainment, commercial transactions, socializing and health. The results show that people assign a relatively low relevance to algorithmic-selection applications compared to offline alternatives across the five life domains. The findings vary greatly by age and education. Altogether, such outcomes complement and qualify assessments of the social impact of algorithms that are primarily and often solely based on usage data and theoretical considerations.

The mediation of love and sexuality has often relied on dating advice. This paper analyses a corpus of dating guides concerning the popular app Tinder. Our analysis suggests that the practice of algorithmic blackboxing, that is, characterizing algorithms as black boxes, is central to these guides that rely on the alleged opacity of Tinder’s algorithms to praise certain products, advice, or services that aim to facilitate matchmaking. The practice of algorithmic blackboxing primarily encourages users to hack Tinder. In this context, the notion of hack stresses the importance for users to modulate their behaviours in ways that make them more algorithmically recognisable, especially in relation to their gender. Thus, we suggest that Tinder’s algorithms participate in reproducing a speculative dating economy.

The impact of artificial intelligence algorithms is widely felt on many different aspects of life, and because of the efficiency and speed of such algorithms, decisions can be taken as well as their implementation on behalf of humans in the field of criminal justice. Despite the progress that has been made, there are still great concerns on the issue of rapid mechanization of the justice sector in general, and the judiciary in particular. Therefore, discussion and analysis of the impact of such algorithms on the justice system in this paper is of high importance. Such discussions will be carried out through three chapters; while chapter one reviews the concept of algorithms and their importance in criminal justice, chapters two and three are devoted to discuss the use of artificial intelligence algorithms in pre-trail and during trail stages respectively. This work, however, ended with a conclusion that contained the main results of the research and recommendations

In the era of the data revolution (Kitchin, 2014), new kinds of data and data sources allow researchers to share innovative ways of studying society and its dynamics to comprehend the peculiarities related to the territory. In fact, the analysis of space-time data extracted from social media can support the comprehension of complex social phenomena such as, for example, mobility (Noulas, Scellato, Lathia, & Mascolo, 2012; Yuan et al., 2017; Zhang et al., 2016) or where and when certain social activities are carried out, such e.g., the participation in big events, tourist experiences or the monitoring and management of emergencies and security. Following the actual dissemination of use of social media in the cities, the analysis of the spatial dimension is considered particularly promising in the field of urban analysis (Singleton et al., 2018) and in the emerging line of digital studies. Nowadays, the intentional action of many people is increasingly contributing to the production and sharing of spatial data with a relevant impact on the construction of Territorial Information Systems (Zupi, 2017). This new category of spatial data is commonly known "Volunteered Geographic Information" (VGI) (Goodchild, 2007). The analysis of this kind of data leads to an innovative scenario for the collection and diffusion of geographic information from millions of users all over the world. It provides valuable insight into their perceptions and needs, opinions on places, events, and daily routes, which allow researchers to better follow traces about the knowledge of the local identities of a given place (Campaign, 2014), information flows, and social networks within society (Stefanidis et al., 2013). However, a clear awareness of the limits of these tools of investigation is needed. For instance, problems may arise regarding representativeness of population, or even technical issues, such as for scarping systems which are not able to offer all the effective amount of data available to the researcher. Despite this, these kinds of studies are taking hold in the social sciences which are paying particular attention to both data and source contextualisation. As a result, they are interesting and valid tools to study issues that classic instruments are not able to perform. Among the different kinds of digital platforms, Twitter allows the combination of textual and geo-referenced data, making this platform an interesting choice, for instance, to detect or monitor different kinds of events (Korkmaz et al.,2015), or it could be used to study the dissemination of influence (Generous et al., 2014). Algorithms are, in this way, extraordinary tools for organising and spreading information. According to these claims, our work aims to understand, both theoretically and methodologically, how the research about territory, as a field of study, has been adapted to prolifically use data coming from algorithms of geo-location or geoparsing (Middleton et al, 2018).Specifically, this work aims to critically discuss the elements and the steps that characterize this emerging approach in order to highlight how the use of geo-localized data can be advantageous for territorial analysis and for which kinds of phenomena..Thus, after showing the most commonly used ways of collecting information about territory using algorithms, we will discuss strategies and techniques of analysis used to combine online (social media) and offline (territorial) sources and try to identify the possible applications for each type of technique. Moreover, a third step allows us to identify the different meanings and operational processes made regarding the concept of territory. That will allow us to recognize the different conceptions of sociological space emerging from the analysis and suggest how to avoid the use of geo-localized data with a simple data-driven perspective (Kitchin, 2014) that does not consider the sociological peculiarities of the space. We will try to answer these questions by examining papers that used Twitter as the source of data. In particular, the analysis of articles will be led thanks to a third kind of content analysis following Rositi’s categorisation (Rositi, 1988). Also, the extraction of the articles will be made using PRISMA methodology (Moher et. Al, 2018) for systematic review.

The article presents a paper on the possible uses of self-organizing maps, especially in classification and data-set visualization purposes, through various examples and approaches. From the point of view of applicability and of statistical problems, the diversity of the examples proposes different characteristic ownership of the self-organizing maps in reference to more traditional methods. The statistical algorithm is presented as a general implementation, which introduces a notion of neighborhood between the classes of the algorithm of the mobile centers. The algorithms of classification take into account at the same time the effects of big distance and local effects. Apart from clustering, self-organizing maps are also useful as a visualization tool for the description of data-set intrinsic structure.

Abstract: A granular structure is an aggregation of grains whose sizes are characterized by a given distribution. A sample of this kind of structure is often modeled by a rectangle filled with disks in two dimensions or a parallelepiped containing spherical balls in three dimensions. Therefore, the geometrical modeling of such a structure consists in determining a “dense” repartition of disjoint disks (or spherical balls) with respect to the specified size distribution. In this paper, a new sphere packing algorithm based on an advancing-front approach, commonly used in meshing methods, is proposed. Significant improvements in computing time and density have been obtained comparing to existing methods. In addition, we show that the generated circular grains can be transformed into polygonal (polyhedral) cells generally observed in reality. An example of a metallic nanostructure model is presented.

Pocket milling is an essential issue in rough milling. Although machining capacities have been strongly modified, no significant evolution was observed about pocket milling trajectories. Trochoïds and plunge milling are new types of strategies which have found practical applications in hard materials rough milling. This paper aims at evaluating their potential in rough pocket milling of aluminium alloys. Algorithms were developed to generate trochoïdal and plunge cutting trajectories for pocket milling, with cycle time optimisation regarding to milled surfaces quality. An experimental campaign has also been done and focused both on productivity and quality issues. Two different high speed milling machine tools were tested: a serial three-axis machine tool and a parallel kinematics five-axis machine tool. The results of this work leads to a better definition of the strengths and weaknesses of trochoïdal milling and plunge cutting strategies in aluminium alloys rough machining with the focus to optimize the choice of strategies.

This paper presents a study of the tool path adaptation to the HSM machining process. The definition of an efficient process imposes the common selection of the milling method and of the cutting conditions. Concerning the tool path programming, the user must choose a milling method and an algorithm dedicated to the part to be machined. The computed tool path does not introduce a reduction of the productivity by appearance of perturbations on the kinematical behaviour of the machine tool and on the mechanical behaviour of the tool. To reduce the influence of the perturbations, CAM software proposes many solutions and options. It is then difficult to choose and to define a machining operation. After an analysis of difficulties due to such part, we present a problem classification. According to the requirement, such classification simplifies the choice of the machining method.

While improving the dynamical performance of a flexible motion control system, additional stresses are generated which induce undesirable vibrations. The design of adequate control algorithms makes it possible to enhance the overall behaviour of the machine while limiting its deformation modes vibrations. This paper presents a comparative study of the influence of different control algorithms on the trade-off between the cycle time and the amplitude of the residual vibrations, which have been applied to a Cartesian robot. While this selection of control algorithms is not exhaustive, these can all easily be implemented in current industrial systems. Each selected control algorithm is analysed along with experimental validations. [ABSTRACT FROM AUTHOR]

Functional tolerancing requires calculating the influence of all the deviations admitted on the parts by their definition drawings according to ISO standards' to check the respect of the functional requirements. The method CLIC (Tolerancing in Localization with Influence of the Contacts) includes algorithms of choice of the specifications, an original and complete 3D method of calculation of the result based on the "analysis lines", at worse cases and in statistic, and a method of synthesis of the tolerances. This paper presents the influence of the deviations of a junction on the requirement and the decomposition of a complex requirement in sub-requirements. A three-dimensional statistical application is proposed with a presentation of the worksheet Microsoft EXCEL. [ABSTRACT FROM AUTHOR]

Abstract: In this paper a new algorithm for detection of suspicious mass area from mammographic images is presented. It uses histogram modification enhancement technique and a segmentation method based on minimization of inertia sum. The histogram modification filter is designed so as to be able to enhance disease patterns of suspected masses by cleaning up unrelated background clutters. Segmentation is then performed on the enhanced-image to localize the suspected mass areas using minimisation of inertia sum of images intensity classes. The proposed algorithm was tested on a database of 32 mammogramms provided by Gynaeco-obstetric and pediatric hospital of Yaoundé on which masses had previously been localised by experienced radiologists. Results show that the algorithm is able to identify masses in all cases presented with a sensibility of 94% approximately. In addition, we found out that sizes and edges of masses detected are similar to those marked by radiologists. Furthermore in some cases, we could detect some hidden masses that the radiologists were not able to mark out. [Copyright &y& Elsevier]

Abstract: The bi-potential method has been successfully applied for the modeling of frictional contact problems in static cases. This paper presents the application of this method for dynamic analysis of impact problems with multiple deformable bodies. A first order algorithm is applied for numerical integration of the time-discretized equation of motion. The numerical results show clearly the physical energy dissipation introduced by frictional effects between the solids in contact. To cite this article: B. Magnain et al., C. R. Mecanique 333 (2005).

Three-dimensional reconstruction techniques are widely used to provide a spatial description of scoliotic spines. One example is the 3-D reconstruction method developed and routinely used at Sainte-Justine Hospital. It concerns the reconstruction of six anatomical landmarks per vertebra from the frontal and lateral radiographs: endplate centers; inferior and superior tips of both pedicles. Although this “standard” method is accurate, it requires 2 h for an expert technician to identify all anatomical landmarks on radiographs.Objective. – Therefore, this paper presents a novel and fast computed acquisition method providing a reconstruction of the spine better suited to the needs of the orthopedists during scoliosis clinics.Materials and Methods. – In this approach, five to eight points are identified on the frontal and lateral radiographs to obtain the overall shape of the spine. 2-D average predictive models, are built from a database of 791 radiographs, allowing to estimate the 2-D coordinates of the six vertebral landmarks and to obtain their 3-D coordinates from the DLT algorithm.Results and conclusions. – The evaluation of this “fast method” shows that the minimum number of points to be identified on the frontal radiograph is six for right thoracic or left lumbar curves and eight for right thoracic–left lumbar curves. Seven points need to be identified on the lateral radiograph. Furthermore, average models corresponding to a specific type and severity of scoliosis allow the 2-D mean differences between “standard” and “fast” methods to be less than 3.7 mm for endplate landmarks and 5.0 mm for pedicles. No significant difference was found between clinical indices obtained from both methods, confirming that the “fast” method is well adapted for direct clinical use. [Copyright &y& Elsevier]

This paper presents a study devoted to the composite fabric shaping simulation in finite strain analysis. We introduce a new geometrical approach based on the fishnet method for which the deformation of a fabric mesh element consists in a pure trellis effect. Such a fabric mesh element is then defined by a curved quadrilateral whose edges are geodesic lines with the same length plotted onto the surface to drape. Given three vertices of the fabric mesh element on the surface, we propose an optimization algorithm to define the fourth vertex of the fabric mesh element. This algorithm allows us to drape the surface using an advancing front approach from the data of an initial impact point between the fabric and the surface and the initial fibre directions at this point. A numerical draping simulation example using this approach is given. To cite this article: H. Borouchaki, A. Cherouat, C. R. Mecanique 331 (2003). [Copyright &y& Elsevier]

It has been argued that the fundamental laws of physics do not face a ‘problem of provisos’ equivalent to that found in other scientific disciplines (Earman, Roberts and Smith 2002) and there is only the appearance of exceptions to physical laws if they are confused with differential equations of evolution type (Smith 2002). In this paper I argue that even if this is true, fundamental laws in physics still pose a major challenge to standard Humean approaches to lawhood, as they are not in any obvious sense about regularities in behaviour. A Humean approach to physical laws with exceptions is possible, however, if we adopt a view of laws that takes them to be the algorithms in the algorithmic compressions of empirical data. When this is supplemented with a distinction between lossy and lossless compression, we can explain exceptions in terms of compression artefacts present in the application of the lossy laws.

This article analyzes the scientific literature on k-means clustering and considers how this method is used in psychological studies, based on a sample of articles. It is shown that the majority of publications contains insufficient description of k-means clustering procedures, which can lead to non-reproducibility of research results. This article describes in detail the general steps to follow to perform a k-mean clustering analysis and the decisions to be taken in accordance with its use in the research practice. Recommendations for further improving the quality of scientific papers using k-means clustering are given.

This paper proposes an initial discussion about the production of automatized journalistic narratives. Despite being a topic discussed in specialized sites and international conferences in communication area, the concepts are still deficient in academic research. For this article, we studied the concepts of narrative, databases and algorithms, indicating a theoretical trend that explains this automatized journalistic narratives. As characterization, we use the cases of Los Angeles Times, Narrative Science and Automated Insights.

The Internet in Canada is an assemblage of private and public networks. A variety of institutions and networking codes manage these networks. Conflicts exist between these parties despite their interconnection. Tensions heightened when commercial ISPs began managing traffic on their network using sophisticated routing algorithms. Concerned parties demanded legislation based on a network neutrality principle to prevent undue discrimination. While the network neutrality controversy has been addressed as a question of public policy, the controversy also includes a conflict between various codes constituting networks in Canada. The conflict between codes involve two key networking software that manifest incongruous networks. Their algorithms, the logics embedded in code, differentiate the different types of networking code. The two types of algorithms are Quality of Service and End-to-End. These algorithms treat different modalities of Internet communication differently, in part due to their deployment by different institutions. Quality of Service allows for the tiering of traffic by carriers. Commercial carriers have popularized this algorithm to promote value-added services and prevent network congestions. End-to-end algorithms, on the other hand, enforce a strict equality between modalities of communication. Peer-to-peer applications have popularized an extreme version of the end-to-algorithm, treating all nodes as equals. The popularity and growth of both these algorithms pulls the Internet in different directions, creating conflicts over its future. Through an extended review of these two algorithms and their intersection, this paper confronts how code plays a role in the network neutrality controversy.
