Mercury$$^\mathrm{\textregistered }$$: A Software Based on Fuzzy Clustering for Computer-Assisted Composition
2019
We present Mercury, a new software for computer-assisted composition based on fuzzy clustering algorithms. This software is able to generate a big number of transitions between any two different melodies, harmonic progressions or rhythmical patterns. Mercury works with symbolic music notation. The software is, therefore, able to read music and to export the generated musical production into MusicXML format. This paper focusses on some theoretical aspects of the CFT algorithm implemented in the software in order to create those complete transitions, overviewing not only the structure of the program but the user’s interface and its music notation module. Finally, the wide variety of compositi…
Fuzzy logic helps to integrate music theory and practice
2010
Among the many practices of composers, instrumentalists and singers which clearly correspond with fuzzy logic our focus here is on tuning. Different criteria have been used to select the sounds that music uses. A set containing these sounds (musical notes) is called a tuning system. Several tuning systems coexist in a classical orchestra. The pitches of the notes are different and very precisely defined for each system; however the consequences of small deviations from these theoretical frequencies are not serious. Actually, the orchestra members are aware of the necessity of reaching a consensus and adjust their instruments to tune well. Because of this, many musicians feel that the mathem…
The kinetics of defect accumulation under irradiation: many-particle effects
1993
The kinetics of Frenkel defect accumulation under permanent particle source (irradiation) is discussed with special emphasis on many-particle effects. Defect accumulation is restricted by their diffusion and annihilation, A + B → 0, if the relative distance is less than the critical distance r0. A novel formalism of many-point particle densities based on Kirkwood's superposition approximation is developed to take into account aggregation of similar defects (A−A, B−B). The dependence of the saturation concentration after a prolonged irradiation upon spatial dimension ( = 1, 2, 3), defect mobility and the initial correlation within geminate pairs is analyzed. It is shown that the defect conce…
Measurement of trace impurities in ultra pure hydrogen and deuterium at the parts-per-billion level using gas chromatography
2018
Abstract A series of muon experiments at the Paul Scherrer Institute in Switzerland deploy ultra-pure hydrogen active targets. A new gas impurity analysis technique was developed, based on conventional gas chromatography, with the capability to measure part-per-billion (ppb) traces of nitrogen and oxygen in hydrogen and deuterium. Key ingredients are a cryogenic admixture accumulation, a directly connected sampling system and a dedicated calibration setup. The dependence of the measured concentration on the sample volume was investigated, confirming that all impurities from the sample gas are collected in the accumulation column and measured with the gas chromatograph. The system was calibr…
Construction of decision support system in business design based on integration of information technology
2016
In an increasingly competitive environment the successful functioning of any business requires continuous improvement of services, expanding the range of products and range of services, standardization, and implementation of new busines ideas, establishment and dissemination of innovative solutions on the market. The implementation of such measures were carried out in a well-developed business projects. Automating business processes often requires the organization of various programs, which creates a problem of integration. The paper attempts to organizations handling business processes through the integration of various software tools. One of the major component due implementing business p…
Are requirements elicitation sessions influenced by participants' gender? An empirical experiment
2021
[EN] Context: Requirements elicitation is a crucial phase in the software development life cycle. During requirements elicitation sessions, requirements engineers capture software requirements, and motivate stakeholders to express needs and expected software functionalities. In this context, there is a lack of extensive empirical research reporting the extent to which elicitation sessions can be influenced by participants' gender. Objective: This paper presents our research endeavour to investigate requirements engineers' effort and elicited requirements' accuracy based on participants' gender. Method: We conducted an experiment in two rounds with a total of 59 students who played the role …
Joint Development of Novel Business Models
2006
Changing competitive environment forces companies to innovate and renew their business models towards a more value-adding and customer-centric direction. Often, a prerequisite for this is that the companies are willing to combine their capabilities by co-operating and creating long-term strategic networks with each other. The formation of networks is a cyclical learning process, along which the infrastructure and strategies emerge incrementally through mutual adjustment. We analyze such network formation process among three companies that are operating in separate but complementary industries. They are seeking to expand their service offering through the use of ICT. We reflect upon this dev…
Exploring Process-Modelling Practice: Towards a Conceptual Model
2008
Despite the importance of process modelling for business process management and related tasks, there are few theories and empirical studies of process-modelling practice available that can serve as the basis for understanding and improving this important practice. To contribute to the development of better theory, this paper proposes a model of process modelling practice, focussing on the relations between process modelling purpose, process modelling process, model artefact, process modelling outcome as well as initial and eventual modelling and process maturity. The proposed model is based on the existing literature and validated in a study of 34 Norwegian process-modelling projects. Resul…
Business Process Models and Information System Usability
2015
Abstract The paper describes the use of business process models for effective managing of information system execution processes and transparent representation of execution statuses. Contrary to traditional approaches where business process models are used only in the initial stages of information system development, the proposed approach suggests direct utilization of business process models during the use of information systems. Information system usability can be improved by using new means of representation, and business process models can serve as an efficient way to visualize execution processes in information systems.
Ge-doping dependence of gamma-ray induced germanium lone pair centers in Ge-doped silica
2008
We report an experimental study on the y irradiation effects in Ge-doped sol-gel silica samples doped with Ge from 10 2 up to 10 4 part per million molar. The samples were exposed to the radiation generated by a 60 Co source up to an accumulated dose value of 10 MGy. Our data evidence that the γ irradiation significantly increases the number of Germanium Lone Pair Centers (GLPC). Such defects are induced with a concentration that depends on the Ge content of the employed material in those samples where no optical activity related to -s GLPC was detected before irradiation. Furthermore an increase of the GLPC concentration was detected also in a sample that already contains this defect after…
