Image fusion in the JPEG 2000 domain

This paper presents a novel approach to image fusion in the JPEG 2000 domain. In this scheme, compressed images are fused without the need for full decompression. The proposed method can be integrated with the existing JPEG 2000 tools. It offers several benefits: it avoids error propagation, allows for the development of error correction and protection mechanisms and reduces computational effort. This paper also presents a comparison with commonly used algorithms for image fusion and studies their performance in the presence of compression and transmission losses. The results show that the performance of the proposed method is superior to currently available techniques under noisy condition

Exploring motivation and clil: a literature review

In this article we intend to explore the history of motivation whithin the field of second foreign language learning. To this end, we will analyse in detail the three most important models: the Socio-educational Model, the Theory of Self-Determination and the L2 Motivational Self System. We will also analyse the relationship between motivation and CLIL, concluding that this approach is very motivating for such students, since they are more motivated than their counterparts who study English in a more traditional way (Doiz, Lasagabaster & Sierra, 2014, Seikkula-Leino, 2007).A través de este artículo se pretende realizar un recorrido por la historia de la motivación en el ámbito del aprendizaje de una segunda lengua o de una lengua extranjera. Para ello, analizaremos en detalle los tres modelos más importantes: el Modelo Socioeducativo, la Teoría de la Autoderminación y el Sistema del Yo Motivacional en L2. Asimismo, analizaremos también la relación entre la motivación y AICLE, concluyendo que dicho enfoque resulta muy motivador para sus alumnos, quienes están más motivados que sus compañeros que estudian inglés de forma tradicional

Relevance of the composition of municipal plastic wastes for metallurgical coke production

This study is concerned with the effects of the composition of mixed plastic wastes on the thermoplastic properties of coal, the generation of coking pressure and the quality of the resulting cokes in a movable wall oven at semipilot scale. The mixed plastic wastes were selected to cover a wide spectrum in the relative proportions of high- and low-density polyethylenes (HDPE and LDPE), polypropylene (PP), polystyrene (PS) and polyethylene terephthalate (PET). From the results it was deduced that the reduction in Gieseler fluidity in the coal blend is linked to the total amount of polyolefins in the waste. It was also found that these thermoplastics increase the pressure exerted against the wall in the course of the coking process and that coke quality is maintained or even improved. However, when the level of aromatic polymers such PS and PET are increased at the expense of polyolefins, the coking pressure decreases. Thus, the amount of aromatic polymers such as PS and PET in the waste is critical, not only for controlling Gieseler fluidity and coking pressure, but also for avoiding deterioration in coke quality (reactivity towards CO CRI and mechanical strength of the partially-gasified coke CSR). An amount of polyolefins in the waste lower than 65 wt.% for a secure coking pressure is established

Identification d'insectes vecteurs "potentiels" du Cape Saint Paul Wilt sur le cocotier au Ghana par PCR

Le vecteur du phytoplasme responsable du jaunissement mortel du cocotier au Ghana est inconnu à ce jour. Il est cependant admis que les phytoplasmes sont transmis par des insectes piqueurs-suceurs, ces insectes étant supposés être les seuls à avoir la capacité d'injecter les phytoplasmes dans les tubes criblés du phloème. Bien que la présence de phytoplasmes dans un insecte ne prouve sa capacité à transmettre la maladie, nous avons testés une grande quantité d'insectes pour la présence de phytoplasmes par PCR (directPCR et NestedPCR), en utilisant des amorces spécifiques des phytoplasmes en général, et du phytoplasme responsable du jaunissement mortel du cocotier en particulier. En effet, la mise en évidence d'une ou plusieurs espèces d'insectes porteurs du phytoplasme pourrait orienter nos recherches pour les essais de transmission en cages par insectes spécifiques.

Teaching english to mixed-ability secondary students through e-tandem

This paper will point out how language and culture can be taught through collaborative work among mixed-ability British and Spanish secondary students belonging to different social backgrounds. We will illustrate how they deal with several topics using e-tandem and autonomous collaborative work and we will discuss the results of their work comparing both groups. Finally, we will refer to the language and cultural exchange we have established thanks to this e-tandem partnership. Este artículo tiene como objetivo mostrar un modelo de aprendizaje del inglés basado en el e-tándem aplicado a estudiantes de secundaria con diferente capacidad. Así, indicaremos la forma en que los participantes abordaron diferentes temas utilizando el etándem y el trabajo autónomo y cooperativo. Para concluir presentaremos un análisis de los resultados del trabajo de ambos grupos de alumnos. Finalmente, nos referiremos al intercambio lingüístico y cultural que hemos establecido como una parte más de nuestra colaboración
