Abstract This article discusses closed-loop systems, namely Cradle to and circular economy, in the context of sustainable education. These models, at least ideally, promise absolute decoupling resource consumption from economy. presents student assignments applying these models Hennes & Mauritz, a clothing retail company, insect food producer, Protix. While discussion economy revolves aroun...

In this paper, an investigation of linear eigenvalue buckling functionally graded material (FGM) plates under uniaxial loading is carried out. The computer model analyzed using the finite element (FE) package ABAQUS. An analysis out to study effect size and geometry openings in FGM plate on critical load. circular, square, diamond vary based ratio opening diameter width plate. Moreover, aspect ...

The basic property of standard laboratory tests is that they are conducted on samples of simple geometry and stress state. It is a common practice to use material parameters obtained from such tests in numerical models that describe more complex stressdependent phenomena. For this reason, numerical modelling results have to be verified either through models or during construction of actual stru...

When mannose is provided in the transpiration stream to spinach (Spinacia oleracea) leaf discs, a series of specific and nonspecific changes occur in CO(2) and H(2)O vapor exchange as a function of feeding time. The initial increases in apparent photosynthesis and transpiration are nonspecific effects due to osmotic changes leading to passive stomatal opening. The mannose-specific effects are: ...

A study of a class of openings and closings is investigated using reconstruction criteria. The main goal in studying these transformations consists of eliminating some inconveniences of the morphological opening (closing) and the opening (closing) by reconstruction. The idea in building these new openings and closings comes from the notions of filters by reconstruction and levelings. In particu...

Stepwise increases in fluorescent illuminance, imposed as a single variable in a controlled environment, induced progressive stomatal opening in 8 plant species, as evidenced by a consistent decrease in leaf diffusion resistance (R(L)), ranging from 15 to 70 sec cm(-1) in darkness to about 1 sec cm(-1) at approximately 40 kilolux. The minimum R(L) values were the same for the upper and the lowe...

In this paper a method for detection of microcalcifications (MCCs), which appear at the beginning stages of breast cancer, is presented by using mathematical morphology. This method consists of four steps. At the first step the contrast of suspicious regions on the image is enhanced by contrast stretching. In the next step a morphological filtering process is applied by using six different stru...

Third-party reviews play an important role in many contexts in which tangible attributes are insufficient to enable consumers to evaluate products or services. In this paper, we examine the impact of professional and amateur reviews on the box office performance of movies. Using a simple diffusion model, we establish an econometrics framework to control for the interaction between the unobserva...

Morphological openings and closings form the cornerstones of a rich set of nonlinear operators in signal processing. In this paper, we show how a new morphological operator can be constructed that serves as an approximation to openings and closings for images corrupted by low levels of noise. 2001 Elsevier Science B.V.
