Factors related to study success in engineering education
2005
Recent studies on student learning in higher education have paid attention to the relationships between characteristics of the learning environment and students' study orientations and study success. The purpose of the present paper is to examine these relationships in university level engineering education. The data were collected from Lappeenranta University of Technology, Finland, by means of an Internet survey (n=394). Grade point average, credits per semester and students' qualitative evaluation of their learning outcomes were used as indicators of study success. The findings of the study indicate that students' perceptions of their learning environment were related to their study orie…
Workshop: iPads in Upper Secondary School Chemistry Education
2014
At the workshop arranged at the National Days of Chemical Education the participants had an opportunity to try out various Ipad apps and methods for utilizing them in chemistry education. The themes were based on the apps used during chemistry teacher education course arranged by the department of chemistry and methods developed on the teacher training school at the University of Jyväskylä. The apps used included Socrative Student, Google Drive, Graphical Analysis, ChemDoodle ja QR-reader. Out of these Socratice, which collects students answers to questions created by the teacher, was considered easy-to-use and the most useful by the participants. The participants also felt, that the worksh…
Reducing the noise pollution level along main roads in Sibiu, Romania by optimizing the traffic flow
2017
Noise pollution is one of the most important negative effects of road traffic, especially in cities. The current paper presents an attempt to reduce the noise level created by the road traffic along some main roads in the city of Sibiu, Romania by suggesting ways to optimize the traffic flow. The number of cars and the resulting noise levels were recorded in a key area of Sibiu. The noise levels were compared to standards and to measurements taken in areas with less traffic. Then, they were fed, together with road geometry data, into a specialized simulation software that allowed the computer-aided reproduction of the traffic flow, but also the modifying of conditions such as the road geome…
Analysis of compressor architectures in MOS current-mode logic
2010
This paper is concerned with the design and the comparison of different compressor architectures for high performance multipliers in MOS current-mode logic (MCML). More specifically, three architectures have been designed for 3-2, 4-2 and 5-2 compressors and two architectures for 7-2 compressors. The various implementations for each type of compressor have been compared one another. This investigation indicates that the architectures based exclusively on three-level MCML gates are the most suitable for MCML implementation in terms of speed, power consumption and area. Design guidelines are provided to improve compressor performance. All the compressors were designed in a TSMC 180nm CMOS tec…
Reverse electrodialysis
2016
Abstract Reverse electrodialysis (RED) technology has grown significantly in the last decade, gaining a fast increase in its technology readiness level and presenting some interesting examples of RED pilot systems operating under very different real environments. In this chapter, an overview of technological developments and piloting examples are reported. In particular, a short introduction is given on the historical trend of RED technology growth, followed by a careful analysis of which feed solutions can be adopted and how these can affect the process performance, potentials, and applications. Most prominent fluid dynamics aspects for the RED process are presented, highlighting how these…
Determining the explosion risk level and the explosion hazard area for a group of natural gas wells
2016
Starting from the fact that the natural gas engineering profession is generally associated with a high occupational risk, the current paper aims to help increase the safety of natural gas wells and reduce the risk of work-related accidents, as well as the occurrence of professional illnesses, by applying an assessment method that has proven its efficiency in other industrial areas in combination with a computer-aided design software. More specifically, the paper focuses on two main research directions: assessing the explosion risk for employees working at natural gas wells and indicating areas with a higher explosion hazard by using a modern software that allows their presentation in 3D. Th…
Preventing early leaving in VET: distributed pedagogical leadership in characterising five types of successful organisations
2010
This paper presents 14 organisers of upper secondary education in Finland with exceptionally low dropout rates. As a case study in which common strengths were defined, five types of organisations with typical characteristics were found: Working life‐oriented, Networked and team‐based, Cosy and traditional, Guidance‐oriented, and Innovative. Distributed pedagogical leadership (DPL) was created as the theoretical basis from which organisational actions were examined. DPL implies that responsibility for students’ learning is shared by the whole personnel, through long‐term and systematic pedagogical practices. For this purpose, the management and leadership, curriculum, strategies, development…
Annual heating energy requirements of office buildings in a European climate
2016
Abstract The concept of implementing energy savings to reduce greenhouse gas emissions has become a key element of energy policies of any industrialized country. In the civil sector and specifically, energy savings for office buildings, there are still opportunities for further enhancements related to correctly determining the air conditioning thermal requirements. However, there is a lack of simple correlations that allow a preliminary assessment for a single building or correlations that can be quickly applied at the district level. This paper proposes several simple correlations that determine the heating loads of a typical office building by only knowing the Degree-Days of a specific Eu…
ORDINAL MEASUREMENTS WITH INTERVAL CONSTRAINTS IN THE EIA PROCESS FOR SITING A WASTE STORAGE AREA
2009
We describe application of multicriteria decision analysis (MCDA) in the Environmental Impact Assessment (EIA) procedure for siting a waste storage area. The world’s largest biofuel-based combined heat and power (CHP) plant was built in Pietarsaari, Finland. The plant produces certain byproducts, such as flue dust and bottom ash, which need to be processed and stored to prevent releases to the environment. Different storage sites will have different impacts on people, nature, and the economy. Cardinal measurement of the different impacts was considered too costly. Instead, ordinal measurement of all criteria was applied; i.e., experts ranked the alternative storage sites according to each c…
Journeys from quantum optics to quantum technology
2017
Sir Peter Knight is a pioneer in quantum optics which has now grown to an important branch of modern physics to study the foundations and applications of quantum physics. He is leading an effort to develop new technologies from quantum mechanics. In this collection of essays, we recall the time we were working with him as a postdoc or a PhD student and look at how the time with him has influenced our research.
