The Civil Engineering course teaches different subjects in its academic program, which has in their educational task to offer knowledge to students, their intervention in the environmental space, within the framework of their actions as future civil engineers. The objective of the research is to reflect on the knowledge acquired in the environmental training of students of the civil engineering career. For this purpose, the standardized survey technique was used with structured questions that collected the work of the educational program of the race and was applied to 75 students of the different levels. The result obtained allowed to know to what extent the environmental training of students, has repercussions on the preparation of future civil engineers, in addition to the degree of concern for environmental problems and the predisposition to work in order to reduce the impacts derived from the professional practice of The Civil Engineering, taking into account the implication of the sustainable development in the academic formation. During the investigation it was verified that students are aware of the importance of preservation and respect for nature through the use of clean energies, where they have expressed concern about contamination and depletion of natural resources. The results obtained can have a positive influence on the constructive future of the province, depending on the implementation of an appropriate sustainable development policy.

This study considers the optimal control of dry bulb temperature and moisture content in a single zone, to be accomplished in such a way as to be implementable in any zone of a multi-zone system. Optimality is determined in terms of appropriate cost and performance functions and subject to practical limits using the maximum principle. Several candidate optimal control strategies are investigated. It is shown that a bang-bang switching control which is theoretically periodic is a least cost practical control. In addition, specific attributes of this class of problem are explored.

Environmental art mainly uses the collocation of color and spatial structure for landscape layout. Different environmental styles have different artistic characteristics. In order to better design the environmental space, this paper puts forward the intelligent analysis method of artistic environmental construction style based on artificial intelligence technology. By analyzing the environment into characteristics and the environmental style into process, the direction of environmental art design is innovated while the environmental design is carried out reasonably.

The Ideal

Despite intensive development of instrumental methods of environmental factors analysis for plant communities their assessment with ecological scales still remains important. The main advantage of ecological scales is their ability to reflect generalized and average characteristics of ecological regimes due to significant inertia in response of plant communities composition to the change of certain characteristics of the environment. The main ways of calculation while using ecological scales are the medium-sized method and the ideal indicator method (of linear regression) including modified algorithm of calculating the level of edaphic and climatic factors of the environment with amplitude ecological scales. The aim of this work was to improve further the method for assessing the level of ecological factors (ecological space) in plant communities. For calculations and visualization of the results obtained we used Excel and our own programs written in the Matlab media. The basis of the method is finding the factor averagely weighed for the level calculated by the traditional way and by the method of the ideal indicator. It is proposed to set the weight of factors in both methods of calculation both explicitly and depending on the ecological index reflecting correspondence (adequacy) of the plant community composition to the level of ecological factors prevailing in the habitat. They can also be calculated by linear or non-linear dependencies relative to the middle of amplitude ecological scale. The conclusion is that it is possible to predict the content of secondary metabolites in plants based on assessing the level of ecological factors for plant communities.

Two benthic mollusc assemblages of the continental shelf on both sides of the Atlantic Ocean, a tropical one in Rio de Janeiro, Brazil, and another, temperate, in Galicia, Spain were investigated, with a view to finding common environmental descriptors which would explain, on a macro-scale, why these assemblages are there. Both of the assemblages concerned show approximately the same species richness, about 150 taxa each. The molluscan fauna of both regions live on sandy sediments. The Galician assemblages are at about 2-12 m depth, while those in Rio de Janeiro are at about 10-40 m depth. Malacological assemblages were defined through Cluster Analysis and Multiple Discriminant Analysis of the environmental data showed that each assemblage has its own environmental space. These assemblages have no species in common, but show the same phenological characters associated with each sedimentological facies. The same set of environmental variables (median sediment grain size, skewness, kurtosis, sorting, fine and medium sand fractions and depth) were selected as controlling these assemblages, suggesting that they play their role as general environmental descriptors.

AbstractScientists are able to gain a substantial understanding of various environmental processes (e.g., physical, chemical, or biological parameters) through environmental sensing and monitoring. Most of these monitoring scenarios involve large environmental space and require a considerable amount of work and time for collecting the required data. Realizing the associated human effort, the data collection process was automated, to some extent, by providing wireless communication capabilities to the sensors. However, with the sensing environments increasing demographically, the location of the sensors moved far apart, necessitating additional relay nodes. This made data collection time consuming and complex. In order to simplify the effort towards data collection by reducing the human involvement to a minimum and to reduce power requirement of the sensors for data transmission, thereby increasing their life, use of marine robotic systems has been experimented with successfully. This article aims to discuss the advancements, trends, and challenges of marine robotic systems for environmental monitoring.
