changes are inevitable in construction projects. they could lead to disruptive impacts on the quality, schedule and budget of projects. identifying changes and anticipating their consequences can help project teams mitigate these negative impacts. as a result, a change process model has been defined to improve this procedure. at first the present paper the defines some of the key terms in this ...

The vast majority of people experience involuntary musical imagery (INMI) or 'earworms'; perceptions of spontaneous, repetitive musical sound in the absence of an external source. The majority of INMI episodes are not bothersome, while some cause disruption ranging from distraction to anxiety and distress. To date, little is known about how the majority of people react to INMI, in particular wh...

Much of our daily communication occurs in the presence of background noise, compromising our ability to hear. While understanding speech in noise is a challenge for everyone, it becomes increasingly difficult as we age. Although aging is generally accompanied by hearing loss, this perceptual decline cannot fully account for the difficulties experienced by older adults for hearing in noise. Decr...

Musicians undergoing long-term musical training show improved emotional and cognitive function, which suggests the presence of neuroplasticity. The structural and functional impacts of the human brain have been observed in musicians. In this study, we used data-driven functional connectivity analysis to map local and distant functional connectivity in resting-state functional magnetic resonance...

Liveness is a well-known problem with Digital Musical Instruments (DMIs). When used in performances, DMIs provide less visual information than acoustic instruments, preventing the audience from understanding how the musicians influence the music. In this paper, we look at this issue through the lens of causality. More specifically, we investigate the attribution of causality by an external obse...

The overarching goal of music theory is to explain the inner workings of a musical composition by examining the structure of the composition. Schenkerian music theory supposes that Western tonal compositions can be viewed as hierarchies of musical objects. The process of Schenkerian analysis reveals this hierarchy by identifying connections between notes or chords of a composition that illustra...

Our study investigated with an implicit method (i.e., priming paradigm) whether I.R. - a brain-damaged patient exhibiting severe amusia - processes implicitly musical structures. The task consisted in identifying one of two phonemes (Experiment 1) or timbres (Experiment 2) on the last chord of eight-chord sequences (i.e., target). The targets were harmonically related or less related to the pri...

Knowledge of the instrumentation of a musical signal at any given time could be useful for major audio signal processing problems such as sound source separation and automated music transcription. Knowing which instruments are playing is a first step toward more intelligently designed solutions to these very important and largely unsolved challenges. So, in this paper, we attempt the problem of...

This paper examines the use of Mel-frequency Cepstral Coefficients in the classification of musical instruments. 2004 piano, violin and flute samples are analysed to get their coefficients. These coefficients are reduced using principal component analysis and used to train a multi-layered perceptron. The network is trained on the first 3, 4 and 5 principal components calculated from the envelop...

The basic principle of motivic pattern extraction consists of detecting repeated motives, i.e. identifying several short extracts or subsequences as instances, or occurrences, of a same series of description called pattern. The approach is focused here on monodic sequences: music is considered as a series of notes without superpositions. Patterns are formalised as chains of states – called patt...
