Oblique rifting and segmentation of the NE Gulf of Aden passive margin
Provedor de dados: 5
Autores: Fournier, M; Bellahsen, N; Fabbri, O; Gunnell, Y.
The Gulf of Aden is a young, obliquely opening, oceanic basin where tectonic structures can easily be followed and correlated from the passive margins to the active mid-oceanic ridge. It is an ideal laboratory for studies of continental lithosphere breakup from rifting to spreading. The northeastern margin of the Gulf of Aden offers the opportunity to study on land the deformation associated with oblique rifting over a wide area encompassing two segments of the passive margin, on either side of the Socotra fracture zone, exhibiting distinct morphologic, stratigraphic, and structural features. The western segment is characterized by an elevated rift shoulder and large grabens filled with thick synrift series, whereas the eastern segment exhibits low...

Vide-omics: A Genomics-inspired Paradigm for Video Analysis
Provedor de dados: 5
Autores: Kazantzidis, Ioannis; Florez-revuelta, Francisco; Dequidt, Mickael; Hill, Natasha; Nebel, Jean-christophe.
With the development of applications associated to ego-vision systems, smart-phones, and autonomous cars, automated analysis of videos generated by freely moving cameras has become a major challenge for the computer vision community. Current techniques are still not suitable to deal with real-life situations due to, in particular, wide scene variability and the large range of camera motions. Whereas most approaches attempt to control those parameters, this paper introduces a novel video analysis paradigm, ‘vide-omics’, inspired by the principles of genomics where variability is the expected norm. Validation of this new concept is performed by designing an implementation addressing foreground extraction from videos captured by freely moving cameras....

Preference study using a latent class approach. Analysis of European preferences for smoked salmon
Provedor de dados: 5
Autores: Semenou, Michel; Courcoux, Philippe; Cardinal, Mireille; Nicod, Huguette; Ouisse, Alexandra.
We present in this paper the advantages of the latent class vector model approach in the analysis of preference ratings. We illustrate the practical application of this methodology on the basis of a preference study of smoked salmons in European countries. A set of 30 samples was selected spanning the characteristic variability of cold-smoked salmon available in six European countries (Belgium, Denmark, France, Germany, Italy and the United Kingdom). Consumers from the main countries of consumption (Belgium, France, Italy, Germany and the United Kingdom) were asked to rate the acceptability of each product. A quantitative descriptive analysis with a trained panel and physical and chemical measurements of smoked salmons were also conducted. Using a latent...

Region based variational approach for the segmentation textured sonar images
Provedor de dados: 5
Autores: Karoui, Imen; Fablet, Ronan; Boucher, Jean-marc; Augustin, Jean-marie.
We propose a new region-based segmentation of textured sonar images with respect to seafloor types. We characterize sea-floor types by a set of empirical distributions estimated on texture responses to a set of different filters and we introduce a novel similarity measure between sonar textures in this attribute space. Our similarity measure is defined as a weighted sum of Kullback-Leibler divergences between texture features. The texture similarity measure weight setting is twofold: first we weight each filter, according to its discrimination power, the computation of these weights are issued from the margin maximization criterion, Second, we add an additional weighting, evaluated as an angular distance between the incidence angles of the compared texture...

Crustal geometry of the northeastern Gulf of Aden passive margin: localization of the deformation inferred from receiver function analysis
Provedor de dados: 5
Autores: Tiberi, C.; Leroy, S.; D'Acremont, E.; Bellahsen, N.; Ebinger, C.; Al-lazki, A.; Pointu, A.
Here we use receiver function analysis to retrieve crustal thickness and crustal composition along the 35-My-old passive margin of the eastern Gulf of Aden. Our aims are to use results from the 3-D seismic array to map crustal stretching across and along the Aden margin in southern Oman. The array recorded local and teleseismic events between 2003 March and 2004 March. Seventy-eight events were used in our joint inversions for Vp/Vs ratio and depth. The major results are: (1) Crustal thickness decreases from the uplifted rift flank of the margin towards the Sheba mid-ocean ridge. We found a crustal thickness of about 35 km beneath the northern rift flank. This value decreases sharply to 26 km beneath the post-rift subsidence zone on the Salalah coastal...

Structure and evolution of the eastern Gulf of Aden: insights from magnetic and gravity data (Encens-Sheba MD117 cruise)
Provedor de dados: 5
Autores: D'Acremont, Elia; Leroy, Sylvie; Maia, Marcia; Patriat, Philippe; Beslier, Marie-odile; Bellahsen, Nicolas; Fournier, Marc; Gente, Pascal.
Magnetic and gravity data gathered during the Encens-Sheba cruise (2000 June) in the eastern Gulf of Aden provide insights on the structural evolution of segmentation from rifted margins to incipient seafloor spreading. In this study, we document the conjugate margins asymmetry, confirm the location of the ocean-continent transition (OCT) previously proposed by seismic data, and describe its deep structure and segmentation. In the OCT, gravity models indicate highly thinned crust while magnetic data indicate presence of non-oceanic high-amplitude magnetic anomalies where syn-rift sediments are not observed. Thus, the OCT could be made of ultra-stretched continental crust intruded by magmatic bodies. However, locally in the north, the nature of the OCT...

Autores: Pellen, Romain; Aslanian, Daniel; Rabineau, Marina; Suc, J.p.; Gorini, C.; Leroux, Estelle; Blanpied, C.; Silenziario, C.; Popescu, S.m.; Rubino, J.l.
Morphological sills condition sedimentary, water and fauna exchanges between different domains. In particular, sills are crucial factors to consider during the Messinian Salinity Crisis (MSC) palaeogeographic evolution (5.97–5.33 Ma) of the NW Mediterranean area. Here we focus on the Ebro River and its up to now unexplained short Messinian onshore length (~100 km) compared to that of the Messinian Rhone River (~480 km) despite similar present-day drainage basins. Thanks to an extensive seismic and borehole dataset, we present a new interpretation of a complete 270 km long Messinian Ebro incised-valley system course underneath the present-day continental margin and bathyal basin and its related distal detrital deposits. These results favour a syn-MSC or...

Variations in axial morphology, segmentation, and seafloor roughness along the Pacific-Antarctic Ridge between 56 degrees S and 66 degrees S
Provedor de dados: 5
Autores: Ondreas, Helene; Aslanian, Daniel; Geli, Louis; Olivet, Jean-louis; Briais, Anne.
The spreading rate at the Pacific-Antarctic Ridge (PAR) increases rapidly from 54 mm/yr near Pitman Fracture Zone (FZ) up to 76 mm/yr near Udintsev FZ, resulting in three domains of axial morphology: an axial valley south of Pitman FZ, an axial high north of Saint Exupery FZ, and in between, the transitional domain extends over 650 km. It comprises sections of ridge with an axial valley or an axial high and generally displays a very low cross-sectional relief. It is also characterized by two propagating rifts. Two domains of different seafloor roughness appear south of Udintsev FZ: east of 157 degreesW these two domains are separated by a 1000-km V-shaped boundary. West of 157 degreesW, the boundary approximately coincides with Chron 3a or Chron 4. The...

Contribution of automatic classification of sonar images for long term registration
Provedor de dados: 5
Autores: Leblond, Isabelle; Legris, M; Solaiman, B.
This issue handles the ability of using segmentation results of sidescan sonar images for long term registration. This study take a part of AUV (Autonomous Underwater Vehicle) navigation problems, particularly to correct the drift of navigation sensors. Principle of images formation with this type of engines and the main properties are first reminded. Some images are shown, which allows us to understand difficulties of this type of data to realise AUV positioning. Then, we decide that segmentation results of sidescan images provide us landscapes on which registration will be able. Segmentation is then explained. It is supervised type on five classes, rocks, ripples, sand, mud and shadow. Using Gabor filters provides classifying parameters and...

We present a detailed 3-D P-wave velocity model obtained by first-arrival travel-time tomography with seismic refraction data in the segment boundary of the Sumatra subduction zone across Simeulue Island, and an image of the top of the subducted oceanic crust extracted from depth-migrated multi-channel seismic reflection profiles. We have picked P-wave first arrivals of the air-gun source seismic data recorded by local networks of ocean-bottom seismometers, and inverted the travel-times for a 3-D velocity model of the subduction zone. This velocity model shows an anomalous zone of intermediate velocities between those of oceanic crust and mantle that is associated with raised topography on the top of the oceanic crust. We interpret this feature as a...

Analysis of calibrated seafloor backscatter for habitat classification methodology and case study of 158 spots in the Bay of Biscay and Celtic Sea
Provedor de dados: 5
Autores: Fezzani, Ridha; Berger, Laurent.
An automated signal-based method was developed in order to analyse the seafloor backscatter data logged by calibrated multibeam echosounder. The processing consists first in the clustering of each survey sub-area into a small number of homogeneous sediment types, based on the backscatter average level at one or several incidence angles. Second, it uses their local average angular response to extract discriminant descriptors, obtained by fitting the field data to the Generic Seafloor Acoustic Backscatter parametric model. Third, the descriptors are used for seafloor type classification. The method was tested on the multi-year data recorded by a calibrated 90-kHz Simrad ME70 multibeam sonar operated in the Bay of Biscay, France and Celtic Sea, Ireland. It...

Un bilan de la télédétection appliquée aux milieux coralliens
Provedor de dados: 5
Autores: Andrefouet, Serge; Maritorena, Stéphane; Loubersac, Lionel.
The aim of this paper is to present in a practical fashion the status of the use of remote sensing for the study of coral reef environments through the analysis of work published in the years 1980-2000. We review the scales of the potential work and of that actually conducted, the principal applications and their limiting factors. We detail these limitations which are of a technological nature (spatial and spectral resolution of sensors), as well as often of a conceptual (role of remote sensing in the study) or methodological (image processing) nature. The understanding of these limitations, in relation to the reality of the field, allows identification of work which could be undertaken in the years 2000.

Autores: Karoui, I; Fablet, R; Boucher, J.m.; Augustin, Jean-marie.
We propose and compare two supervised algorithms of the segmentation of textured sonar images with respect to seafloor types. We characterize sea-floors by a set of empirical distributions estimated on texture responses for a wide set of different filters with various parameterizations and we introduce a novel similarity measure between sonar textures in this feature space. Our similarity measure is defined as a weighted sum of Kullback-Leibler divergences between texture features. The weight setting is twofold. First each filter is weighted according to its discrimination power: the computation of these weights are issued from a margin maximization criterion. Second, an additional weight, evaluated as an angular distance between the incidence angles of...

Image Analysis of Oxidative and Glycolytic Muscle Fibers During Reperfusion Injury by Segmentation Based on Regions
Provedor de dados: 77
Autores: Rosero-Salazar,Doris Haydee.
Different situations cause ischemia and reperfusion injury, affecting tissues under the level of compression. In this research, abnormal characteristics in distribution of muscle fibers types in soleus and extensor carpi radialis longus, during short periods of ischemia and short and long periods of reperfusion, were determined. Fibers were classified by enzyme histochemistry techniques NADH-TR and myosin-ATPase. Measurements of areas were carried out through semiautomatic image processing by using segmentation based on regions, which evidenced significant changes in distribution during reperfusion followed to one and three hours of ischemia, as well as in comparisons of areas for all periods of reperfusion. This study strengthens the evidence about using...

A structuralist approach in the study of evolution and classification
Provedor de dados: 16
Autores: Hammen, L. van der.
A survey is given of structuralism as a method that can be applied in the study of evolution and classification. The results of a structuralist approach are illustrated by examples from the laws underlying numerical changes, from the laws underlying changes in the chelicerate life-cycle, and from the laws underlying the evolution of the chelicerate appendages. Suggestions are given for the study of the laws underlying the transformation of form, and some notes are made on structuring forces and the early stages of organic evolution. Some concluding remarks are finally made on deep structure, phylogenetic classification and evolution.

Consumption patterns in the market of pork and pork products
Provedor de dados: 31
Autores: Szakaly,   Zoltan; Horvath-Kovacs,   Bernadett; Polereczki,   Zsolt; Nabradi,   Andras.
Pork is a source of nutrients essential for the human body but still it is regarded by consumers as a non-healthy product. The main objective of the study was to analyse consumption patterns concerning pork products and to define alternative target markets in bigger Hungarian towns. In the course of the research, 494 people, representative of the base population, were questioned. According to the results obtained, the consumers’ opinion and the already formed image are less favourable regarding pork than poultry in almost all respects. Respondents regarded pork as an out-of-date, slightly boring and aging product. The applied cluster analysis identified five different consumer segments. Among them, rational young consumers represent the primary target...

CHARACTERISTICS OF DIFFERENT CONSUMER SEGMENTS IN THE AUSTRALIAN BEEF MARKET
Provedor de dados: 31
Autores: Morales,   Luis Emilio; Griffith,   Garry R.; Wright,   Vic; Umberger,   Wendy J.; Fleming,   Euan M.
Beef consumers in Australia have shown differences in their preferences for products and sensitivity to price. This can be explained by the influence on expected quality of cues related to health, production process and eating experience. Eating experience is difficult to predict as consumers generally do not have enough information to form reliable expectations. In this context, branded beef can help to signal quality and reduce the degree of uncertainty that consumers experience when shopping. Focus group research identified different segments, premiums for preferred products and potential for large-scale differentiation and branding in the Australian market.

Trade-offs Between Consumer Concerns: An Application for Pork Production
Provedor de dados: 31
Autores: Meuwissen,   Miranda P.M.; van der Lans,   Ivo A.C.M.
This paper studies multiple attributes of pork production and analyses the trade-offs that consumers make between them. Results show that without considering the trade-offs, animal welfare and food safety are on average perceived as the most important attributes. However, including trade-offs, Taste and Price become major concerns. Conclusions are nuanced as for a number of segments and specific trade-offs Taste and Price are relatively less important. Results support the implementation of differentiated chain designs with distinct and innovative decisions for trade-offs to be made.

THE IMPACT OF PROMOTION AND ADVERTISING: A LATENT CLASS APPROACH
Provedor de dados: 31
Autores: Richards,   Timothy J.
Typically, marketers define market segments by their demographic characteristics, assuming that these segments represent consumers with relatively homogeneous buying patterns.  A more managerially useful definition, however, groups consumers of similar behavior directly and then seeks to find demographic commonalities among them.  This study uses a latent class analysis technique to segment consumers based on their responsiveness to a set of marketing variables, finding that a multiple-segment model provides a better fit to the data, and that these segments differ significantly in their responsiveness. By targeting marketing activities to their most responsive segments, the efficiency of commodity promotion can be dramatically improved.

Autores: Bojnec,   Stefan.
This paper focuses on agro- food chains and agro- food consumer prices in Slovenia considering its European Union (EU) membership. As the Slovenian agro- food markets were distorted prior to the EU accession with some agro- food prices that were greater than comparable EU prices, the empirical results confirm that with the EU membership Slovenian real agro- food consumer prices have largely downward adjusted. Besides policy changes, internalization of retailing and distribution chains by entries of supermarket s and hypermarket s have had impacts on market structures and rationalization of marketing activities. Supermarket s and hypermarket s are taking over a substantial proportion of retail trade in agro- food products with implications on increasing...

Autores: Nocella,   Giuseppe; Stefani,   Gianluca; Romano,   Donato.
Lack of consumer trust and communication strategies are probably the main determinants of information failure in modern food markets. This study attempts to tackle these aspects affecting the quality of food information by investigating questions related to what topics are more relevant to consumers, who should disseminate trustful food information, and how communication should be conveyed. Primary data were collected both through qualitative (in depth interviews and focus groups) and quantitative research. Quantitative research was conducted by means of a questionnaire administered in 2006-2007 to a sample of Italian respondents using both a web and a traditional mail survey.

Public Policies and the Demand for Vegetables
Provedor de dados: 31
Autores: Gustavsen,   Geir Waehler; Rickertsen,   Kyrre.
Increased consumption of vegetables may reduce obesity and the prevalence of cardiac diseases and cancer. Norwegians consume less vegetables than nutrition experts recommend and the per capita consumption is lower than in most European countries. To investigate the causes of low consumption, a two-step approach is used to estimate the demand segmented by nine different household types. In the first step, a probit model is estimated to investigate the decision whether to purchase traditional vegetables, salad vegetables, and industrially processed vegetables. Conditional on purchase, an almost ideal demand model is used to model how much to purchase. The own-price elasticities and total expenditure elasticities are high for traditional and industrially...

In our paper we are aiming to present food preference as a way of consumption typical of the individuals and consequently, a way of eating characterising working days. To carry out a more detailed preference examination, factor analysis was carried out followed by cluster analysis based on the segmenting effect of food consumer preferences. The role and the main features of institutional catering were analysed in comparing the segments of the whole sample and research. We assume that the differences outlined on the level of food preferences are reflected in choosing the way and circumstances of eating thus influencing the choice between several alternatives typical of working days.

The truffle consuming behaviour is strongly related to the prestige (hedonist, snobbish, imitator and ostentatious) consuming motivations. We have analysed the consuming behaviour on a domestic representative sample (1060 people older than 16) and 113 persons were consumers of meals with truffle.

We have defined three consumer segments that were characterised with the demographic factors, frequency of consumption and the behaviour characteristics. We have analysed buying behaviour on sample of 63 restaurants.
