Abstract. The purpose of the paper is to design a fishing strategy in order to regulate an exploited fish population. To this end, we use a stagestructured model of a harvested fish population that has been derived in [5]. We give a formula for the fishing effort as a feedback control that allows to stabilize the system. travail réalisé avec la contribution financière du CNCPRST (Maroc) et du C...

Brun., 2012, LX, No. 8, pp. 299–306 The current scientifi c methods describing gardens and landscapes all over the world are not always suffi cient for the purpose of deep understanding of specifi c and close relations between landscape/ garden and its inhabitants/visitors. A new ...

Gardens represent important sources of goods and services for their owners. This functionality translates directly into the types of plants cultivated in a given garden, and terminology has been developed to distinguish each category of garden according to its purpose. The factors explaining the differentiation and distribution of gardens have not previously been explored at the global scale. I...

We show new results about the garden-hose model. Our main results include improved lower bounds based on non-deterministic communication complexity (leading to the previously unknown Θ(n) bounds for Inner Product mod 2 and Disjointness), as well as an O(n · log n) upper bound for the Distributed Majority function (previously conjectured to have quadratic complexity). We show an efficient simula...

Aluminium toxicity is a major crop production constraint, particularly in acid tropical soils. The toxicity is aggravated when pH falls below 5.5 since toxic monomeric Al species get solubilized. The screening of Al tolerance intrinsically depends on culture medium, with a nutrient solution having pH of 4.5 being recommended. Hydroponic experiment was carried out at Jomo Kenyatta University of ...

the pavilion can be outlined among the most important architectural identity elements in persian gardens. usually these structures were built in the middle of the garden and at the confluence of two longitudinal and transverse axes in such a way that it could be seen from four sides to maximize the geometrical composition of the persian four-garden. although relatively different reasons for the...

This paper describes a practical method of developing custom HPC software products using a store of libraries and tools independent from the OS called a "garden". All dependencies from the product to libraries of the underlying OS distribution are carefully severed, isolating the package from instability due to system upgrades and ensuring repeatable deterministic builds on different flavors of...

The Secret Garden is an interactive narrative potential space, which aims to be a hidden rest area in urban space and a site to interrogate and reflect on the human experience. A digital image of the tree with its ‘will’ to grow stands in the space. A spectator’s secret will feed the tree. JeeHee’s The Secret Garden installation suggests a cross-art form. Sound, light and visualisation will des...
