Integrated development environments (IDEs) increase programmer productivity, providing rapid, interactive feedback based on the syntax and semantics of a language. A heavy burden lies on developers of new languages to provide adequate IDE support. Code generation techniques provide a viable, efficient approach to semi-automatically produce IDE plugins. Key components for the realization of plugins

Particle generation from humans is a severe problem when working in cleanrooms and other controlled environments. Data regarding the number of particles generated by humans are few and there are no detailed references as to how these studies have been performed. An experimental method to determine the particle release from a human being in a cleanroom was developed and used to describe the variati

The use of passive house technique has been used in a new wood framed building in Sweden. Besides the positive effect of reduced energy need, highly insulated wooden houses often have a higher risk of moisture and mould problems. The reason is that critical positions is more exposed to higher relative humidity compared to ordinary houses with thinner insulation. To investigate if an external wall

In this work, we present a built-in filter method to enhance the isolation level between closely packed MIMO antennas. The built-in filter is composed of several slits etched on the ground of the antenna structure. The number and length of slits depend on both the resonance frequency and the structure of the MIMO antenna system. To illustrate its usefulness, two designs of compact planar four-port

Numerical analysis, such as the finite element method is the most used computational procedure for nonlinear deformation and strength analysis of structures. In order to obtain meaningful results the material behaviour must be described and simulated accurately. Another important element in order to perform the simulation is a robust and accurate numerical integration algorithm. The present paper

Recently, there has been considerable interest in the internal reforming reactions of solid oxide fuel cells (SOFCs) using methane or natural gas via. The internal reforming and electrochemical reactions appear in the porous anode layer, and may lead to inhomogeneous temperature and gas species distributions according to the reaction kinetics. A three-dimensional calculation method has been furthe

In this work, we present implementation and experiment of the theory of dynamic force sensing for robotic manipulators, which uses a sensor fusion technique in order to extract the contact force exerted by the end-effector of the manipulator from those measured by a wrist force sensor, which are corrupted by the inertial forces on the end-effector. We propose a new control strategy based on multis

A frame of reference is presented intended to capture conditions that influence the usability of information technologies, primarily computers, in a society. The frame of reference includes four components that influence one another: 1. External physical conditions, 2. Economic resources (including other technological resources), 3. Social actors and their interests, and 4. the Understanding, con

The explosive popularization of personal computers during the last decade, along with the appearance of the World Wide Web and of high-level programming techniques, has opened many new and exciting opportunities in the field of education. In this chapter, a review of existing types of multimedia material used in education and of some of the authoring tools used in the production of this material i

During the last decade, a new design of schools with fan assisted natural ventilation has been introduced. Experience and knowledge of this type of ventilation system is therefore needed. The objective of the project is to study the technical and physical conditions required to ensure satisfactory ventilation. The whole project includes analyses of the air flows for different combinations of outdo

Mathematical morphology is a powerful means to specify image manipulations; discrete-time cellular neural networks (DT-CNN) is the fast realization. The attractive combination has been sufficiently shown for simple problems but tends to fail in efficiency for more complex ones. The paper introduces a complement and argument swap (CAS) equivalence that allows to solve an image processing problem th

Intra cerebral tumours were inoculated into the brain of Fischer-344 syngeneic rats. After one week they were treated with either 5 or 15 Gy of Co-60-gamma radiation. The first immunization was given 1 hour before the radiation treatment and then two more times with 14-day intervals. Immunization was performed with 3 x 10(6) radiation sterilized IFN-gamma secreting tumour cells (N29) injected intr
