Segmenting customers according to online word-of-mouth about hotels
2021
There is a renewed interest in the study of online word-of-mouth behavior due to the increasing use of the Internet and the development of social networks. This paper focuses on the receiver perspective to analyze the unequal influence of the antecedents of online consumer searches. The main purpose is to detect the heterogeneity of the effect of different motivations (convenience, risks reduction and social reassurance) and the volume of comments on the willingness to check online reviews. Based on 393 guests of hotels, a mixture regression model indicates the existence of three internally consistent segments, which reveal the varying influence on consumer intentions to look at online comm…
Market Timing with Moving Averages: Anatomy and Performance of Trading Rules
2015
The underlying concept behind the technical trading indicators based on moving averages of prices has remained unaltered for more than half of a century. The development in this field has consisted in proposing new ad-hoc rules and using more elaborate types of moving averages in the existing rules, without any deeper analysis of commonalities and differences between miscellaneous choices for trading rules and moving averages. The first contribution of this paper is to uncover the anatomy of market timing rules with moving averages. Our analysis offers a new and very insightful reinterpretation of the existing rules and demonstrates that the computation of every trading indicator can equiva…
MRI (Magnetic Resonance Imaging) in Psychiatry
2001
In recent years, structural and functional magnetic resonance imaging has opened up new avenues to the study of psychiatric disorders. A number of structural changes characteristic for different psychiatric diseases could be delineated by the use of magnetic resonance imaging (MRI). Functional magnetic resonance imaging (fMRI) enables the in vivo investigation of cerebral neuronal activation under cognitive or behavioral activation paradigms. Magnetic resonance spectroscopy (MRS) allows for the study of defined neurochemical substances or pharmacological agents in the human brain. This article presents an overview of the basic principles of the different MRI techniques and representative re…
Investigating the effect of residual stress on hydrogen cracking in multi-pass robotic welding through process compatible non-destructive testing
2021
Abstract In this paper, the effect of Welding Residual Stress (WRS) on the size and morphology of hydrogen-induced cracks (HIC) is studied. Four samples were manufactured using a 6-axis welding robot and in two separate batches. The difference between the two batches was the clamping system used, which resulted in different amounts of welding deformation and WRS. The hydrogen cracks were intentionally manufactured in the samples using a localised water-quenching method, where water was sprayed over a specific weld pass in a predetermined position. The Phased-Array Ultrasonic Testing (PAUT) system was implemented during the welding process (high-temperature in-process method), to detect the …
Minimizing the cycle time in serial manufacturing systems with multiple dual-gripper robots
2006
Robots are being used more and more extensively as material-handling systems for automated manufacturing systems. This is especially true for dual-gripper robots whose in-process buffer (the robot's second gripper) constitutes a further element of flexibility. When the number of stations to be served is high and the set of activities the robot must execute is great, the system throughput may depend on robot capability rather than on process times. In such conditions, the use of several robots leads to an increase in system productivity. Obviously, the design and the management of such a handling system becomes more complex: the minimum number of robots required, the work stations to be serv…

Locating a Waste Treatment Facility by Multicriteria Analysis
1997
We describe an application of multicriteria decision aid to the location of a waste treatment facility in eastern Finland. In Finland, the Act on Environmental Impact Assessment Procedure requires that when the amount of waste to be dealt with in a facility exceeds 20,000 tons per year, the process of environmental impact assessment (EIA) must be performed. In addition, the opinions of citizens and different interest groups need to be heard. Generally, EIA requires many different factors to be dealt with. Therefore the use of some multicriteria decision aid may be helpful to preserve the information obtained through the EIA in the decision-making process. The alternative locations for the f…
The effect of time and place dependence when utilizing video lectures
2009
In many learning institutes, diversification of teaching with the help of various technologies has become an essential part of educational arrangements. With the increase in the use of networks for teaching purposes, the use of streaming videos is now one of the possibilities to be reckoned with in trying to increase flexibility in studies. Specially recorded on-demand videos provide the students with better chances to decide when, where and how to study. Information on how students use on-demand videos can be obtained, apart from student questionnaires, from the log files of a media server. These files offer an information source that, on the one hand, is diverse but, on the other, cumbers…
Diversification of adult education with the help of video lectures
2010
For some years now, adult education and working while studying have had an important role in the modern society. Mature-age study brings with it some special features, such as time use limitations, which must be taken into account when creating educational programmes for the students concerned. Above all, flexibility must become a major feature of participation in education. In relation to the Master Studies in Mathematical Information Technology at Kokkola University Consortium, the aim for some years now has been to increase that flexibility by diversifying traditional lecture teaching with the help of real-time and on-demand video lectures. With the help of the results presented in this …
