Multicriteria Decision Analysis for Choosing the Remediation Method for a Landfill Based on Mixed Ordinal and Cardinal Information

2009

We describe a real-life application of a multicriteria method in the context of remediating a landfill in Finland. The landfill was used for dumping industrial waste during the years 1950 to 1965. During that time many harmful chemicals were stored in landfills among other waste. Therefore, this—and possibly several other—landfills have to be remediated. In this application, seven different remediation options were evaluated based on 13 criteria. For some criteria, cardinal measures with associated uncertainties were obtained. For other criteria, only ordinal (ranking) information was available. The problem was analyzed using the Stochastic Multicriteria Acceptability Analysis with Ordinal …

Distance and coupling: analyzing the pressures of accounting change in a city

2008

PurposeThe purpose of this paper is to analyze the accounting performance measurement (PM) change process in a Finnish city.Design/methodology/approachInterpretive case study. Data consisted of 16 semi‐structured interviews. Analysis was based on institutional theory, particularly on “new institutional sociology” (NIS) studies.FindingsBudgeting and accounting PM became coupled into action when various intertwined (mostly institutional) pressures affecting change converged. Perceived crises were found to accelerate accounting change by deinstitutionalization, i.e. by breaking (drastically) existing routines and myths. Further, accounting rules and routines changed somewhat independently. Fur…

Using Cellular Automata for feature construction - preliminary study

2007

When first faced with a learning task, it is often not clear what a good representation of the training data should look like. We are often forced to create some set of features that appear plausible, without any strong confidence that they will yield superior learning. Beside, we often do not have any prior knowledge of what learning method is the best to apply, and thus often try multiple methods in an attempt to find the one that performs best. This paper describes a new method and its preliminary study for constructing features based on cellular automata (CA). Our approach uses self-organisation ability of cellular automata by constructing features being most efficient for making predic…

Five Years of Game Programming Outreach : Understanding Student Differences

2014

This paper presents lessons learned from five years of teaching a five-day game design and programming outreach course. The course was offered in summer time and targeted at middle and high school students. In total, 462 youngsters have taken part in 21 course instances. We describe our course concept, and discuss our successes and challenges. In particular, we focus on understanding our student populations by presenting descriptives and statistics of the events, and performing a statistical cluster analysis based on pre- and post-surveys. The cluster analysis was complemented with an analysis of the qualitative data, also originating from the surveys. Taken together, students could be clas…

Life two years after a game programming course: longitudinal viewpoints on K-12 outreach

2012

In our faculty we have run week-long K-12 game programming courses now for three summers. In this paper we investigate what programming-related activities students do after they take a course, and what factors in the students' background relate to post-course programming. We also investigate a possible change in the students' interest towards higher education science studies. We find that most students continue programming after the course and that their interest towards science studies keeps increasing. In student background we observed some indicative trends, but did not find reliable explaining factors related to post-course programming or increased interest towards science studies.

Low Level Languages for the PAPIA Machine

1986

The paper presents the low-level languages implemented up to date to program the PAPIA machine. The parallel assembly-level P-MAGRO package, the microcode level instruction set and a machine simulating environment are described.

Photo-Induced Luminescence

2008

The present paper is a critical review dealing with the characteristics, reaction mechanisms and photoproducts, instrumentation and analytical applications of the photo-induced either chemiluminescence or fluorescence. Special attention is paid to the determination of pesticides by continuous-flow methodologies. The paper is divided into several sections covering the most relevant published papers.

A distributed genetic algorithm for restoration of vertical line scratches

2008

This paper reports a distributed algorithm for the restoration of still frames corrupted by vertical line scratches. The restoration is here approached as an optimisation problem, and is solved using an ad-hoc Genetic Algorithm. The distributed algorithm is designed following a pipeline logical structure. The front end is a network of standard workstations with heterogeneous operating systems. The quality of image is appreciable and the computational time is quite low with respect the sequential version.

2020

This work introduces a method to estimate reflectance, shading, and specularity from a single image. Reflectance, shading, and specularity are intrinsic images derived from the dichromatic model. Estimation of these intrinsic images has many applications in computer vision such as shape recovery, specularity removal, segmentation, or classification. The proposed method allows for recovering the dichromatic model parameters thanks to two independent quadratic programming steps. Compared to the state of the art in this domain, our approach has the advantage to address a complex inverse problem into two parallelizable optimization steps that are easy to solve and do not require learning. The p…
