The Journal of Macro Trends in Technology and Innovation Development strategies for the French construction sector

In 2008, Europe entered a deep recession causing the industrial production to drop by 20%. In an attempt to redress the situation, many strategies were set by industrials to gain market share. The construction sector, however, still struggles to secure a positive margin. Furthermore, this sector is known to be the least efficient in terms of industrialization, process improvements, procedures, and technology application. In other words, waste is generated throughout the construction value chain. All these factors tend to predict a great development potential, estimated at 70% in 2025. This paper presents an overview on the construction field and the applied research conducted in this sector to improve its efficiency and productivity. The paper also investigates the future trends of the construction industry, particularly in the French market.
Observations of loading‐unloading process at Saturn's distant magnetotail

Using in‐situ measurements from the Cassini spacecraft in 2013, we report an Earth substorm‐like loading‐unloading process at Saturn's distant magnetotail. We found that the loading process is featured with two distinct processes: a rapid loading process that was likely driven by an internal source and a slow loading process that was likely driven by solar wind. Each of the two loading processes could also individually lead to an unloading process. The rapid internal loading process lasts for ~ 1–2 hours; the solar wind driven loading process lasts for ~ 3–18 hours and the following unloading process lasts for ~1–3 hours. In this letter, we suggest three possible loading‐unloading circulations, which are fundamental in understanding the role of solar wind in driving giant planetary magnetospheric dynamics.
SoftMF: A Software Defined Moving Fingerprinting Framework for Proactive Security Policies Enforcement

Networks such as in campuses and enterprises are suffering enormous attacks and threats. Traditional solutions are passive in nature, which lacks effective and speedy threat detection and mitigation abilities. This work combines flow watermarking with software-defined technology to propose a novel watermarking-based dynamic fingerprinting framework, called SoftMF (Software-defined Moving Fingerprinting), which introduces a watermark hopping mechanism integrated into edge switches and actively injects dynamic watermarks into network traffic. These dynamic watermarks are used as flows’ fingerprints for active security policy enforcement. SoftMF supports flexible and active defense strategies, such as access control, flow linking, stepping-stone detection and attack backtracking.
Capture & Analysis of Active Reading Behaviors for Interactive Articles on the Web

Journalists, educators, and technical writers are increasingly publishing interactive content on the web. However, popular analytics tools provide only coarse information about how readers interact with individual pages, and laboratory studies often fail to capture the variability of a real‐world audience. We contribute extensions to the Idyll markup language to automate the detailed instrumentation of interactive articles and corresponding visual analysis tools for inspecting reader behavior at both micro‐ and macro‐levels. We present three case studies of interactive articles that were instrumented, posted online, and promoted via social media to reach broad audiences, and share data from over 50,000 reader sessions. We demonstrate the use of our tools to characterize article‐specific interaction patterns, compare behavior across desktop and mobile devices, and reveal reading patterns common across articles. Our contributed findings, tools, and corpus of behavioral data can help advance and inform more comprehensive studies of narrative visualization.
An Automatic Parkinson ’s Disease Recognition System Based on Multi - Feature Selection of Motion Signals

Parkinson’s disease (PD) seriously affects human health so it has wide application value for its automatic diagnosis. In this study, 5 wearable inertial sensors were used in acquiring the acceleration and angular velocity signals under 4 paradigm actions. Total of 27 features were extracted from the signals, including amplitude, frequency, fatigue degree, self similarity, cross correlation and approximate entropy of an action. Genetic algorithm and BP neural network was used for feature selection and data classification. The experiment data were acquired from 10 PD patients and 10 healthy subjects. The results showed that the classification efficiency was improved after feature selection, and the average sensitivity, specificity and accuracy of the classification were 87%, 100% and 93% respectively. It may have certain application value in computer aided diagnosis of Parkinson’s disease.
Representations of street networks in space syntax towards flexible maps and multiple graphs

The shift from Axial to Line-segment maps is one of the most important developments in Space Syntax analysis, both theoretically and methodologically. It followed a long line of investigations and discussions within the field of Space Syntax, which addressed critical issues related to the Axial map representation (e.g. Hillier and Iida,2005; Hillier,1999a,1999b; Turner,2001; Steadman,2004, Dalton, 2001). At the same time, it opened up new possibilities by allowing for the use of Road-centre-line maps in Space Syntax analysis; that is, largely available GIS-based segment maps, used in most areas of urban modelling (e.g. Turner,2007; Dalton et al.,2003). Today, several models implement syntactical analysis to Road-centre-line maps, while claiming to form valid alternatives to the Axial map, not least in capturing the perceptual and cognitive affordances presented by the environment. This paper focuses on such alternative models with a twofold aim: first, to help make well-grounded choices in applying syntactical analysis to Road-centre-line maps; and second, to explore the methodological potentials of Line-segment maps, which are created by their flexibility, by being the least aggregated representations of street networks. The paper introduces an experimental software application to push the investigations and exploit these methodological possibilities even further. The models discussed in this paper are: 1) Angular Segment Analysis (e.g. Turner,2007; Hillier and Iida,2005); 2) Natural Streets maps (Jiang and Liu,2007) and Continuity maps (Figueiredo and Amorim,2005); 3) Directional Distance model (Peponis et al.,2008). Based on a systematic comparison of: a) their geometric representation of the street network (the ‘map’), b) the dual- graph they calculate, and c) the measure of distance they use, we argue that they can all be seen as parametrically defined representations, based on a Line-segment map. In other words, with the same Line-segment map one could produce all of them, if a different set of angular parameters was used, to either define the graph elements (nodes, edges), or to calculate distance. These models, parametrically redefine the relation between the ‘map’ and the ‘graph’; thus, challenging the one-to-one relation between the two, that the Axial map was founded upon. The methodological importance of this development goes beyond the specific models described in this paper. If the same Line-segment map can produce different graphs by using a different set of angular parameters, then, for instance, one could easily change the parameters to follow the latest theoretical insights on human cognition, without having to change the map. Going even further, one could develop and test different representational models to explore new theoretical and methodological paths, by using one single map. The experimental tool also presented in this paper is a step in that direction, allowing to test different models using a single software.
Spatio-temporal variability in abundance, size and microhabitat associations of early juvenile Nassau grouper Epinephelus striatus in an off-reef nursery system

Nassau grouper Epinephelus striatus is a reef fish that settles in off-reef nursery habitats before emigrating to coral reefs. Because little is known of its habitat use and population dynamics before moving onto reefs, we conducted monthly visual censuses from May to December (3 to 10 mo post-settlement) to quantify spatio-temporal variability in density, microhabitat use, and size-struc- ture in a cohort of early juvenile Nassau grouper residing in an off-reef nursery system in the central Bahamas. Juvenile Nassau grouper density decreased significantly from August to September, but this decrease was small compared to a decrease of over 90% during the first 3 to 4 mo post-settle- ment, a pattern consistent with Type III survivorship. Throughout the study, Nassau grouper had a disproportionately high association with the macroalgae Laurencia sp. , while other microhabitats (e.g. seagrass, corals) were usually used in proportion to their availability. Percent cover of Laurencia sp. significantly influenced spatial variability in fish density during May and June (4 to 5 mo post-set- tlement), but not later in the year. Spatial differences in juvenile Nassau grouper density later in the year were correlated with spatial variability in the size distribution of fish. Sites harboring dispropor- tionately high numbers of large juveniles also had greater juvenile densities. Thus, microhabitat characteristics were determined to influence the spatial distribution of Nassau grouper up to 5 mo post-settlement, but the population appears to be influenced by size-dependent processes (e.g. pre- dation or ontogenetic habitat shifts) after that time. Microhabitat characteristics, as well as spatially variable growth rates or size-dependent mortality may cause nursery areas to vary in their contribu- tion to the local population at subsequent life history stages.
Unfolding perspectives on networked professional learning: Exploring ties and time

Networked learning and learning networks are commonplace concepts in most contemporary discourse on learning in the 21st century. This special issue provides a collection of studies that address the need for a growing body of empirical work to extent the limited understanding of the use and benefits of networks in relation to learning and professional development. In this article we attempt to offer a synthesis of the studies presented in this special issue and reflect on their findings. The studies in this issue present a rich combination of networked professional learning research addressing issues related to the composition and structure of learning networks, their content and activities, showing how multi-faceted research in the field of networked learning really is. Based on the findings and methods used in the articles in this issue, we articulate some recommendations for further research. The recommendations are focused on the need for advanced multi-level analysis to understand the complexity of learning ties, the need for employing a multi-method research approach to triangulate and contextualize findings, the need to conduct process and time-based analysis and finally the need to further develop a theory and toolkit for applying Social Network Analysis in the context of networked learning.

R U ready 4 new subtitles? Investigating the potential of social translation practices and creative spellings

In this paper I investigate novel and creative linguistic features used in non-conventional subtitling settings such as fansubbing, arguing that they can be advantageously used in professional subtitling practices for a specific medium, such as the Internet. The integration of txt lingo in subtitling is supported by the recent explosion of social translation practices as a response to an ever-growing audience fragmentation as well as changes in technology which make the integration of several customised subtitling tracks possible. In an attempt to provide empirical evidence to support this argument I present the initial results of a pilot eye-tracker-based experiment to elicit data on the reception of “unregimented” subtitling when offered as an alternative to conventional subtitling from consumers in selected new subtitling contexts.
The Role of Extracellular Protease Produced by Vibrio anguillarum

Vibrio anguillarum の病原機構におけるプロテアーゼの役割およびプロテアーゼの免疫病原性について検討した。 V.anguillarum を感染させた魚の体内においてプロテアーゼ抗原の存在が確認された。 ウナギおよびアユを予めプロテアーゼで処理することにより, V.anguillarum に対する魚の感受性が高められた。 ウナギ血清の殺菌作用は10μg/ml以上のプロテアーゼで処理することにより非働化血清と同程度のレベルまで低下した。 プロテアーゼで注射免疫したウナギおよびアユには感染防御効果が認められたが, 浸漬免疫したアユでは対照区より死亡率が高かった。
Inulins (chicory fructans) improve recovery of broilers after a challenge with Eimeria acervulina and Clostridium perfringens.

In a dose-response study, the effects of dietary inclusions of a chicory fructan preparation (RaftifeedIPE (IPE)) were studied on growth performance from 1 to 35 d of age in a subclinical Eimeria/Clostridium challenge model with male broilers. The challenge comprised oral inoculations of the birds at 10 d of age with Eimeria acervulina and at 14, 15 and 16 d of age with Clostridium perfringens. The IPE was included in a maize/soya (starter) diet and in a wheat/barley/soya (grower) diet and the inclusion levels were: 0 (control), 3, 9 and 20 g/kg diet. The birds were kept in floor pens. Each dietary treatment comprised 8 replicates of 22 birds. On day 15, 16, 17, and 22, two birds per replicate were necropsied to determine the numbers of lesions related to coccidiosis (Coc) and necrotic enteritis (NE). Feed intake (FI) and body weight gain (BWG) were measured over four periods: preinoculation (1-9 d of age), during the period with the inoculations until six days thereafter (10-22 d of age), from 23 to 28 d and from 29 to 35 d of age. Clear Coc and NE lesions were observed: The average percentages of birds with lesions were on d 15, 100 and 44; on day 16, 100 and 49; on day 17, 88 and 47 and on d 22, 2 and 10 for Coc and for NE, respectively. Mortality over the period from 9-35 d of age was 3.3%, which demonstrates the subclinical impact of the challenge. Positive effects of the fructan preparation on performance were observed in each of the four periods but differences were only statistically significant in the pre-inoculation period (0-9 d of age) and in the period 23-28 d of age (FI, P<0.001; BWG, P<0.001). During the inoculation period, the positive effects of fructans were limited to an effect on FI (P<0.05). In summary: The effects of fructans on performance during the inoculations with pathogenous bacteria and parasites were limited. However, after the inoculations clear positive effects on performance were observed suggesting a more rapid recovery after the challenge.
ELECTROMAGNETIC BRAKE ASSISTED POSITIONING SYSTEM – INVESTIGATING CONTROL LAWS FOR NEW PROTOTYPE

The mechanical machining has great economic importance in the industry and constant efforts are made to incorporate technological advances in automation, control, computing and mechanical precision, resulting in more accurate and automated machines, therefore providing major improvements in the production of medium and large batches. However, few technological advances have contributed for improving the economic viability of machining small batches such as prototypes, research devices, unique equipment or pieces, or even parts of dedicated production machines. A workshop dealing with production of small batches or unique parts should possess a high production flexibility, which is usually obtained by human operators and manual machines, being more flexible than any automated system since the operator is able to take complex unexpected decisions faster. Manual machines also have lower initial cost with respect to automated ones. Several studies have been done in order to improve the performance of human operator in performing tasks, without aiming its automation and preserving the autonomy of the operator to take decisions. Thus, some cooperative robotic devices were developed, being completely passive and assisting the work of the operator through virtual computer-generated barriers, restrictions or fixtures, imposed by passive actuators. When this concept is applied to manual machining, it results in a system that helps the operator in positioning the cutting tool, reducing the time required for machining and increasing its quality. The resulting system can be considered a manual assisted positioning using virtual constraints or fixtures. Therefore, the proposed concept requires an actuator able to introduce these restrictions on human operation with performance and reliability compatibles with the precision required in the machining operation. In this context, the most appropriate actuators are the brake actuators, that are only capable of dissipating energy, hence avoiding any instability or harm in the system and being able to generate a large dissipative force in relation to its size and energy consumption. In particular, the friction-based brakes have: high braking force to size ratio, high braking force to energy consumption ratio and a very simple construction. Using an electromagnetic brake, that is regulated by the voltage applied to it, and a position encoder, that gives the actual position and speed, preliminary work conducted by the authors showed that it is possible to obtain reasonable accuracy with a simple control algorithm. This work presents the control strategy and results of positioning simulation conducted for a new prototype of the positioning system. Also, this work discusses the improvements in the control algorithm to increase the positioning accuracy maintaining the impedance type control, i.e., without measuring directly the involved forces to impose a virtual barrier, but only its position and speed.
Normally-off operation AlGaN/GaN MOS-HEMT with high threshold voltage

Normally-off operation AlGaN/GaN high electron mobility transistors have been developed utilising a fluorine-based treatment technique combined with a metal-oxide-semiconductor gate architecture. Threshold voltage as high as 5.1 V was achieved by using an 16 nm-thick Al2O3 gate oxide film. Additionally, the device performed a drain current density of 500 mA/mm and a peak transconductance of 100 mS/mm, which are comparable to the conventional normally-on devices.
