File replaced 2022–02–24: Erroneous stratigraphic levels in figures 8, 9, 10 and 11 of the original publication are now correct Heat storage Danish subsurface is gaining increasing interest for optimiz-ing use energy resources, but no deep heat facilities have yet been established. As an analogue we study Gassum Formation Stenlille structure that presently used gas storage. This allows us to di...

In thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. In this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. The model is used to predict the steady state profiles of the gas temperature and product yields. Using ...

SchemaSQL is a recently proposed extension to SQL for enabling multi-database interoperabil-ity. Several recently identiied applications for SchemaSQL, however, mainly rely on its ability to treat data and schema labels in a uniform manner, and call for an eecient implementation of it on a single RDBMS. We rst develop a logical algebra for SchemaSQL by combining classical relational algebra wit...

In this paper, a comparative assessment is made based on time domain specifications and erro r criteria between various types of controllers like conventional PID, and heuristic approaches like FA, P SO and BFO based PID and I-PD structured controllers. The dynamic modelling of pitch control system i s considered on the design of an auto pilot that controls the pitch angle. To study the effecti...

Th e performance of a mean field theory (MFT) neu ral network technique for finding approximate solutions to optimi zation problems is invest igat ed for the case of the minimum cut graph bisectio n problem, which is NPcomplete. We address the issues of solut ion quality, progr amming complexity, convergence tim es and scala bility. Both standard random gr aphs an d mor e st ruct ured geomet ri...

We present a constructive method for the study of observability or partial observability of weakly coupled linear distributed systems or, more generally, of compactly perturbed systems. This approach allows us to avoid the usual indirect compactness{uniqueness arguments in many cases. It is based on two ideas: a detailed study of the dependence of some constants on the initial data and on a gen...

This paper deals with the constrained reconstruction of 3D geometric models ofobjects from range data. It describes a new technique of global shape improvementbased upon feature positions and geometric constraints. It suggests a general incre-mental framework whereby constraints can be added and integrated in the modelreconstruction process, resulting in an optimal trade-o b...
