Comparative Analysis of Four New Alternative Types of Roundabouts: “Turbo”, “Flower”, “Target” and “Four-Flyover” Roundabou
2016
Analysis of literature shows that “modern roundabouts” nowadays exist in all European countries, as well as in more than 60 countries elsewhere in the world. Nowadays, a growing number of studies, presented in scientific and professional literature, point out a poor traffic safety characteristics of “standard” two-lane roundabouts and lower capacity then was expected. These problems are resolved in more ways in different countries; however the solution, whereby the number of conflict spots is diminished has proven to be the most successful. Lower number of conflict spots is one of characteristics of the alternative types of roundabouts. The alternative types of roundabouts are usually more …
Exploring FPGA‐Based Lock‐In Techniques for Brain Monitoring Applications
2017
Functional near‐infrared spectroscopy (fNIRS) systems for e‐health applications usually suffer from poor signal detection, mainly due to a low end‐to‐end signal‐to‐noise ratio of the electronics chain. Lock‐in amplifiers (LIA) historically represent a powerful technique helping to improve performance in such circumstances. In this work a digital LIA system, based on a Zynq® field programmable gate array (FPGA) has been designed and implemented, in an attempt to explore if this technique might improve fNIRS system performance. More broadly, FPGA‐based solution flexibility has been investigated, with particular emphasis applied to digital filter parameters, needed in the digital LIA, and its …
A multi-agent system reinforcement learning based optimal power flow for islanded microgrids
2016
In this paper, a distributed intelligence algorithm is used to manage the optimal power flow problem in islanded microgrids. The methodology provides a suboptimal solution although the error is limited to a few percent as compared to a centralized approach. The solution algorithm is multi-agent based. According to the method, couples of agents communicate with each other only if the buses where they are located are electrically connected. The overall prizing system required for learning uses a feedback from an approximated model of the network. Based on the latter, a distributed reiforcement learning algorithm is implemented to minimize the joule losses while meeting operational constraints…
Linguistic Repertoires and Semiotic Resources in Interaction: A Finnish Manager as a Mediator in a Multilingual Meeting
2010
This article examines professional communication in a multilingual meeting in a small company in Finland within ethnographic, sociolinguistic, and discourse analytic frameworks. English is used as a lingua franca by a group of Finnish and Chinese business professionals. The aim is to study how language is used with other semiotic resources to construct meaning in interaction. In particular, with the focus on an individual participant who was the mediator in the meeting, the goal is to analyze participants’ role alignment and interpersonal relationships. The results show that business professionals’ roles are renegotiable in a meeting and by means of language accompanied by embodied actions …
A New HLA-Based Distributed Control Architecture for Agricultural Teams of Robots in Hybrid Applications with Real and Simulated Devices or Environme…
2011
The control architecture is one of the most important part of agricultural robotics and other robotic systems. Furthermore its importance increases when the system involves a group of heterogeneous robots that should cooperate to achieve a global goal. A new control architecture is introduced in this paper for groups of robots in charge of doing maintenance tasks in agricultural environments. Some important features such as scalability, code reuse, hardware abstraction and data distribution have been considered in the design of the new architecture. Furthermore, coordination and cooperation among the different elements in the system is allowed in the proposed control system. By integrating …
The Startup Scratch Book – Opening the Black Box of Startup Education
2021
Teaching entrepreneurship and startups is a challenging task. Approaches using real or simulated entrepreneurship as a teaching method are also common in startup education. However, as educators and researchers, we typically only observe the outcomes of the startup journey between weekly lectures and other meetings, whereas the actions taken by the student teams can seldom be observed. This makes the process a black box. All valuable learnings, realizations, and big ideas happen in the students’ minds, and little evidence exists to say what happened during the course. As a result, we are entirely missing out on the most critical elements of the learning process. To remedy this issue, we pro…
Team collaboration capabilities as a factor in startup success
2018
[EN] This paper discusses the role of team collaboration as a building block for cultivating capabilities in technology-based startups. This conceptual framework draws on a literature review of innovation and entrepreneurship research to understand the intra-organization collaboration mechanisms among team members in technology-based startups. Introducing the concept of team collaboration capabilities represents a new approach to understanding the interaction conditions that give rise to new capabilities from a venture team as its organizational base. Rapid new capability building represents a competitive advantage in environments characterized by innovative technological change, known as d…
Effect of Integrating Photovoltaic Systems on Electrical Network Losses Considering Load Variation
2018
Planning of Distributed Generation (DG) units in the power distribution networks is an important issue, one of the most important considerations that is directly affected by installing DG units is the power losses. Improper allocation of DG units to the grid can lead to a noticeable increase in the power losses. Moreover, the load variation is considered as critical matter when studying the optimal scenario that minimizes the power losses in the network. The aim of this paper is to investigate the effect of integrating photovoltaic (PV) units on the distribution network losses considering load variation. The optimal parameters of the DG units were calculated for the various load demands in …
A field methodology to study effects of UV radiation on fish larvae.
2003
There is a considerable lack of in situ specific information about the effects of UV-B radiation on limnic animals studied in the field. We exposed larval pike (Esox lucius L.) in two types of cuvettes (glass and quartz) placed at different depths (5 or 15 cm) to natural solar UV or to artificially enhanced UV-B (lamps on 3 h per day), simulating the scenarios for coming decades. Dose realism and comparability with earlier laboratory experiments was the main purpose, and therefore UV-B irradiances to the surface as well as underwater irradiances were directly measured. Result showed that UV-B dose rates in natural waters are low even though DOC concentration was low (4.8 mg/l) in our study …
A modular approach in teaching thyristor rectifiers with equation-oriented softwares
2014
This article is devoted to some issues of teaching power electronics in university courses. In the modern education system the students are expected to be no longer subject of passive learning, but that, within a certain extent, they collaborate in their training interactively with the teacher to develop the applications and the topics of the studied framework. For this purpose, this article presents a modular approach for teaching module regarding three-phase thyristor rectifiers. A simulator based on the MATLAB equation solver has been developed by considering the detailed physical operation of such converters. In particular, the realized simulator takes various aspects into account, incl…
