The paper reviews a number of cellular neural network implementations on a field-programmable gate-array. It illustrates experimentally, how these implementations can be used to measure from images or to create dynamic, autonomous processes that facilitate measurements within topographic maps. Applications range from image understanding to robot navigation
This paper explores the concept of peer-to-peer learning (P2PL) in the context of North-European small-scale forest owners. The aim is to develop a framework for initiating new and evaluating already existing forest owners’ P2PL communities. Design: Previous studies of peer-learning are used to determine and justify eight dimensions for forest owners’ P2PL. To demonstrate and test the operability
The main objective was to compare short wave radiation from Thorn lamp to solar radiation. In sun all manikin front zones get more or less evenly radiated but in the lab the radiated power reaches some zones more than others. Tests were carried out on the thermal manikin Tore under clear sky in a building corner facing the sun. The manikin was turned so that in the end of each trial the sun faced
Given the uncertainty and complexity of security risk analyses, there is a great need of tools for contextual inquiry supporting assessment of risk with multi-value scales according to different stakeholders’ point of view. Such tools can be used at individual level to help develop the understanding of a problem space. At the collective level, they can be used as a mean of communication to support
We present an optimal adaptive controller that is used to regulate the chemical process of wood ash stabilization (WAS). The model parameters of the time-varying process dynamics are estimated using recursive least squares (RLS). At each batch an auto-tuning sequence produced with the controller disabled is carried through in order to obtain a good estimate of the process dynamics. After the auto-
When investigating different location and/or system designs the possible variables to take into consideration can differs between the alternatives. Different production system will have different optimal working conditions and hence should be compared with parameters suitable for the actual production system. When planning production and calculating production costs the batch size is of high inter
Artificial neural networks is one of the most commonly used machine learning algorithms in medical applications. However, they are still not used in practice in the clinics partly due to their lack of explanatory capacity. We compare two case-based explanation methods to two trained physicians on analysis of electrocardiogram (ECG) data from patients with a suspected acute coronary syndrome (ACS).
Abstract Digital visualization has gone through a revolutionary decade. Compared to other fields where these methods have been applied, archaeology has been, and still is, more resistant to integrating tools and instruments able to describe materials and scenarios with high resolution. This is partly due to the archaeological misconception of high cost of scientific equipment and the complexity in
We consider wireless systems with maximal-to the different transmit antennas are weighted replicas of ratio combining diversity at the base station, and hybrid selection/maximal ratio combining at the mobile station. We have recently proposed these systems, which provide high-quality data links, while keeping the complexity at the mobile station low. We analyze their performance in various realist
In many organizations it is considered of vital importance to translate its vision and strategy into objectives, to determine the best means of achieving these and to review the results – with participation from all members, from management to shop floor. The objective of this study was to make a first test of a method that could be applied for verbalizing and communicating a common vision and ide
The multiple-year drought that started in 2011 and reached climax in 2015 was the most severe and prolonged one in the semiarid northeastern (NE) Brazil in recent decades. This study aimed to investigate the reservoir surface water volume (SWV) variation in NE Brazil from 2009 to 2017 in four representative regions covering a total area of approximately 10,000 km2 there and encompassing 2,140 rese
Vacuum cleaner motor is an air cooled single-phase induction motor with impeller. Its compact design can result in more than 2 kW of input power per 1 kg of mass. It can operate only if an air flow is cooling the motor; otherwise it is overheated and destroyed. A large production volume of a vacuum cleaner motor classifies it as a mass production product. In the past its development has been mostl
Spatial data are playing an increasingly important role in watershed science and management. Large investments have been made by government agencies to provide nationally-available spatial databases; however, their relevance and suitability for local watershed applications is largely unscrutinized. We investigated how goodness of fit and predictive accuracy of total phosphorus (TP) concentration m
We present a compact HHG source driven by a few-cycle, few μJ, 200 kHz OPCPA system. Efficient harmonics are generated from Neon, Argon and Krypton with conversion efficiency of 4.0×10-8, 1.2×10-6 and 4.1×10-6, respectively.
Text visualization techniques often make use of automatic text classification methods. One of such methods is stance analysis, which is concerned with detecting various aspects of the writer's attitude towards utterances expressed in the text. Existing text visualization approaches for stance classification results are usually adapted to textual data consisting of individual utterances or short me
Buildings are getting taller due to increased urbanisation and densification of cities. More advanced construction methods and the desire to construct impressive buildings is also supporting the trend. Due to their inherent slenderness resulting in low eigenfrequencies, these buildings are susceptible to wind-induced vibrations which can be highly disturbing for occupants. Already barely perceivab
The number of patients affected by Alzheimer's disease among the population is currently growing, while the availability of resources for their assistance is decreasing. A solution for this problem is provided by the use of Ambient Assisted Living technologies, with the objectives to prolong the independent living of patients at home, to relieve assistance burden on caregivers, and to improve care
This article describes field monitoring and supplementary simulations of an existing daylighting and electric lighting integrated design for a furniture store. First in its type, the store includes several areas of the showroom provided with abundant daylighting. For the monitoring, the areas of the living rooms and the home decoration exhibitions were selected. They include wide glazed areas, day
