Given the accelerated changes and deeply interconnected activities of the times we are living in, creativity is a key factor of disruptive future developments. Creative and entertainment industries nowadays represent more than 3% of the GDP in Europe and they range from creative content providers (TV & radio, fashion, music) through creative experience providers (movies and music experience) to creative services providers (advertising, design, architecture).

Creative services, contents and experiences present knowledge requirements that are defined increasingly beyond a single discipline and appear to lie in a sound engagement among the creative practitioner (artist/designer/composer/entertainer), the engineer and the scientist. Digital arts, creative industries, and (tele)communication + (social) signal processing speak the language of convergence rather than autonomy. Their interaction calls for special attention now more than ever.

The journal is not limited to only specific aspects of creative technologies but also open to considering the high-level and innovative contributions from a wide range of subfields, especially articles of interdisciplinary nature.

Some of the journal topics are:

Creative Industries - the paper can describe a whole industrial project or framework integrating creative technologies for domains such as:

Creative content providers: TV & radio (broadcast, linked media), fashion (RFID and sensors, energy recycling), music & movies, books (digitization, sonification), museums (creative/artistic installations for tourism or cultural heritage) and media archives, etc.
Creative services providers: Advertising (user-centered web and ads optimization), design (communication devices for creative environments), architecture (places that adapt to people, creativity from domotics), new media and transmedia, etc.
Creative experience providers: Movies and music experience, game-based installations and playable media (participative creation, DJs and VJs creative tools), interactive social and urban spaces, etc.

Scientific topics - the paper can focus on scientific tools for creative industries on topics such as:

Creative content management: Multimedia data mining and innovative browsing, data 2D/3D visualization, digitization and storage, cultural heritage, etc.
Creative interactions: Social signal processing, verbal and nonverbal, explicit or implicit interactions, interacting robots, sensors and MoCap, human-computer interaction, user interface design, serious game etc.
Creative experiences: Affective content analysis and synthesis, immersive technologies, special effects, augmented reality, expressivity and emotion detection and processing, user experiences, etc.

Additional materials such as videos of installations and setups, public/users reactions and comments, or demo links are welcome.

The application uses mobile phones for data retrieval and mapping, to design an invisible skin of a city (an output map) following a user journey at a given moment in time. The project explores relations between subjectivity and raw data by combining hard data with visual mapping. Cities and their intrinsic diversity can be compared. Slightly different input variables can present greater changes in a recurrent path. CitySkin records the mood of a specific dérive and prompts consideration of the cultural implications of computing and the design of its ubiquity.

But the access to this content may be difficult especially
when using a basic telephone without browsing capability and only a GSM network. The only means of text-based
communication remains through SMS. Due to the limitation of the number of characters, a Wikipedia page cannot always
be sent through SMS. This work raises the issue of text summarization with character limitation. To solve this issue, two
extractive approaches have been combined: LSA and TextRank algorithms. Generated summaries have been evaluated using
ROUGE metrics. Since ROUGE metrics do not consider character limitation, a new threshold named Threshold of
Acceptability for Character-Oriented Summaries (TACOS) has been proposed to appreciate ROUGE metrics. The evaluation
showed the relevance of the approach for pages of at most 2000 characters. The system has been tested using the SMS
simulator of RapidSMS without a GSM gateway to simulate the deployment in a real environment. To the best of our
knowledge, this is the first work tackling text summarization issue with character limitation.

We provide a short introduction to the ubimus ﬁeld, highlighting the diﬀerences with other technologically based approaches to music making. One of the objectives of ubimus research is to expand the range of the stakeholders that participate in creative music making. This is achieved through the development of metaphors for creative action by means of sociotechnical systems that target creativity, including ecologically based creative practices, interaction aesthetics, computational thinking and dialogics applied to music. Another objective entails a push for new forms of music making through the reappropriation of extant technologies or through the design and deployment of new behavioral, material or social resources tailored for ubiquitous music ecologies. Nevertheless, so far, few projects have considered the future creative actions as an object of research. This is the aim of anticipatory ubiquitous music.

They have the potential to improve our daily life and social welfare. But, the introduction of AI already brings some technologic, industrial and regulatory challenges. The robots operating autonomously, without the intervention or awareness of humans will raise questions regarding attribution of rights or restrictions / obligations for them, liability for their actions, taxation, data privacy, robotic labour replacing human labour. The change of liability paradigm from the operator of the vehicle to the manufacturer started with the imposition of liability for damages arising from an autonomous car. Should robots pay taxes? Maybe it is not fair to tax artificially intelligent agents for benefiting from public expenditure, because the use of public services or infrastructures by an AI agent it’s not a benefit for the agent, but for the user or designer. It can be a necessity, for reasons related to altering patterns of consumption or employment within the economy. The risk of losing control over AI agents are not only related to damages, but also to the protection of personal data and public safety. This can happen due to malfunctions, security breaches, the superior response time of computers compared to humans, unsafe explorations, hacking and so on. In this paper we aim at demonstrating that, with the proliferation of artificial intelligence, questions will come up and legal frameworks will inevitably need to adapt.

The availability of internet with such a low cost is making audiovisual content a more popular and easier form of
information exchange. The internet is having a huge amount of this audiovisual content and to classify and choose a
particular type of video is becoming a difficult task. A number of video classification methods (like text, audio and video
feature extraction) have been proposed by researcher’s community.

OBJECTIVES: This work is carried out to give a review of different video classification techniques and give a
comparative analysis of available video classification techniques and to suggest the most accurate and efficient method of
video classification.

METHODS: Text, Audio and Visual video classification techniques.

RESULTS: It has been observed that a combination of audio and visual feature extraction can provide better results.

CONCLUSION: There are various methods of video classification either by using text, audio or video extraction. The text
feature extraction is the least used method of video classification. The audio and visual feature extraction is being used in
various applications but as we can understand that both the audio and visual feature extractions are having equal
importance in video feature extraction but if we use combination of both these approaches, the results in form of accuracy
of video classification can be further improved.

anomalous behaviour in digital and digital/physical systems.

OBJECTIVES: We aim to define design guidelines to both support authors in the process of creating sonifications that are
both efficient and engaging and the transition of sonification into a mass medium for the representation of data in everyday
life.

METHODS: Through two Design Actions, we apply Design Research to the definition of the use case, the interaction
paradigm and the experimental protocol for real-world evaluation of sonification tools.

RESULTS: Two Design Actions are described. Methodologies and results of the first experimental phase are presented in
detail along with their influence on the second phase, currently ongoing.

CONCLUSION: We sketch a tentative design-driven process for sonifications for the real-time monitoring of anomalous
behaviour in digital and digital/physical systems.

performer itself. This instrument is composed by two parts: an interface (a sensor glove), which relies on the movements
of the performer’s hand, and a computational engine (a set of patches developed in Max 7), which generates sound events
based on the genomic data of the performer.

OBJECTIVES: We want to propose a new reflection on the relation between the body and musical instruments. Moreover,
we aim to investigate the voluntary and involuntary aspects of our body, intended as a starting point for a musical
performance. As a metaphor of these two layers, we used here the hand and the genome of the performer.

METHODS: We have investigated our objectives through the whole design process of a Digital Musical Instrument, using
a practice-based approach.

RESULTS: Our system is a multilayered composed instrument which maps its computational part and its interface on the
performer’s body. Silico can be used as a standalone musical instrument to generate music in real time.

CONCLUSION: Our works shows a new path about the use of genomic data in a musical way, as a new perspective of
human-computer interaction in a performative contexts.

OBJECTIVES: …INTRODUCTION: Starting from et ego, a piece for classical guitar and electronics, this paper aims to introduce the notion
of the interactive system as a tool to understand the musical activity developed by a composer and/or performer in
relationship with an instrument and a score.

OBJECTIVES: The primary objective is to show how the equilibrium within this interactive system can be affected by the
introduction of an external technology.

METHODS: In et ego, the external technology is represented by two piezoelectric contact microphones placed on the
soundboard of the guitar, which creates an interference within the usual performer/instrument relationship. The performer
has to interact with these microphones and with a differently amplified classical guitar: the piezoelectric microphones make
very tiny sounds audible and emphasize percussive sounds while feeding the patch for the live electronics. Consequently,
the composer enacts different strategies to understand and represent this enriched vocabulary.

RESULTS: The use of piezoelectric microphones allows for working with specific gestures and extremely delicate sounds,
enriching the vocabulary of sound material available within the compositional process. The use of notation becomes part of
this process of comprehension and translation of different aural images.

CONCLUSION: The interdependencies between the agents of the system, constantly challenged by different levels of
interferences, reveal the perceptual and recursive nature of the compositional labour.

visuals in dance performances.

OBJECTIVES: We investigated four conditions: motion capture, sensors, camera image, and minimal
interaction; and four variables: how much did the audience perceive a connection between the body and the
visuals; the visuals as merely copying the dancer; how much distracting were the visuals; and how much did
the audience enjoy the visuals.

METHODS: We used a questionnaire to collect data. We analyzed it using Friedman’s test, and Spearman’s
correlation test.

RESULTS: The audience perceived a stronger connection in the camera condition, but in the same condition,
visuals tend to be merely copying the dancer. We also suggest that the perceived connection has a positive
correlation with enjoyment, while distraction has a negative correlation.

CONCLUSION: Our results help to highlight the impact that different technology have on live visuals for
dance.

This study reports on research into the impact of digital technological interventions for including kids with attention and developmental dificulties into school class contexts. The paper describes, how the authors have approached the challenge of researching inclusion of kids with attention and developmental deficits for communication, collaboration and knowledge sharing. Some of the questions addressed in the study are: How – and in what sense - may technology and technological interventions be utilised to enhance this approach with our focus learners? In which situations does it occur in the case study? The data analysis assesses the potential of interventions with digital technology for acting as stimulating enzymes for life and learning. On the basis of a thorough discussion of the analysis and findings, the authors assess the degree to which interventions with digital technologies may promote inclusion through stimulating the participation in life and learning of kids with attention and developmental deficits.

The conventional method of calling name of each student is time consuming and there is always a chance of proxy attendance. The following system is based on face recognition to maintain the attendance record of students. The daily attendance of students is recorded subject wise which is stored already by the administrator. As the time for corresponding subject arrives the system automatically starts taking snaps and then apply face detection and recognition technique to the given image and the recognize students are marked as present and their attendance update with corresponding time and subject id. We have used deep learning techniques to develop this system, histogram of oriented gradient method is used to detect faces in images and deep learning method is used to compute and compare feature facial of students to recognize them. Our system is capable to identify multiple faces in real time.

Considering that Art reflects social, cultural and sometimes political realities, we identify types of messages that an artwork using advanced technological might transmit to us, spectators or artists. This paper focusses on the Cyborg Theatre, whereby the technology is its inherent element without which the performance could not happen. Such a technological performance cannot occur without a body. We refer here to a cyborg body as a human organism extended with mechanical parts, which integrate non organic components in order to gain meaning within the artwork. By focusing on such a theatrical performance, we observe a relationship developing between the performer and the spectator. This is an unusual interaction, which deserves our attention. We claim that both the performer and the spectator take part in a social event that does not only represent societal realities, but also indicates future ones.

To overcome the future needs of data communication on mobile devices, the $ 3^{rd} $ Generation Partnership Project (3GPP) has introduced a new technology which is known as Long Term Evolution (LTE) UMTS. In this paper, we study video streaming behavior on the LTE network. For this purpose, we use the Vienna LTE System Level Simulator which implements network features that correspond to our goal. We consider the parameters that may affect the users experience on a network and define ten scenarios for our simulations. We finally search for methods to fit the video streaming data traffic on the LTE network and exhibit its long range dependence.

Highly complex models are a requirement for the successful delivery of many scenes and environments. While workflows such as rendering, compositing and animation have been streamlined to accommodate increasing demands, modelling complex models is still a laborious task. This paper introduces the computational benefits of an Interactive Genetic Algorithm (IGA) to computer graphics modelling while compensating the effects of user fatigue, a common issue with Interactive Evolutionary Computation. An intelligent agent is used in conjunction with an IGA that offers the potential to reduce the effects of user fatigue by learning from the choices made by the human designer and directing the search accordingly. This workflow accelerates the layout and distribution of basic elements to form complex models. It captures the designer’s intent through interaction, and encourages playful discovery.

The device differs from many traditional haptic feedback implementations in that it combines vibrotactile feedback with gesture based input, thus becoming a two-way conduit between the user and the virtual environment. The device is intended to challenge what is considered an “interface” and sets out to purposefully blur the boundary between man and machine. This allows for a more immersive experience, and a user evaluation shows that the intuitive interface allows the user to become the aircraft that is controlled by the movements of the user's hand.

Recent studies have shown a significant gap between design frameworks and gamified products, reflected in a lack of consistency, integrity, measurement and a comprehensive process that covers the different phases to achieve a quality
gamified product. For this purpose, a specific quality model software for evaluation is required. Our contribution consists of making an analytical and qualitative study of the existing Gamification frameworks and platforms, with the aim of proposing a model for quality evaluation of the gamified applications. This proposal is based on the patterns and attributes determined during the conducted bibliographic study and comparative studies, with an attempt
to integrate the ISO 25010 quality model.

Abstract:
In this paper, a 15.5W Si-LDMOS balanced RF power amplifier has been designed using 2.620-2.690GHz frequency band to improve efficiency and linearity for 5G-LTE mobile applications.

The amplifier was designed and simulated using large signal Si-LDMOS transistor model to achieve 53% PAE, 41dBm Pout, 14 dB gain at P1dB saturation point. The proposed balanced RF power amplifier was fabricated and measurement results for phase variation of the signal between the carriers have been the main focus. At 1dB compression point power added efficiency increased to 81.5% with 19.5 gain at the Pout. The AM-AM and AM-PM measured data of the balanced RF power amplifier was extracted from the MATLAB fitting tool to produce polynomials. The polynomials were used in the proposed pre-distortion technique to compensate for the nonlinearities of the balanced power amplifier. A simple linear model was designed for behavioural modelling of the memory-less baseband digital pre-distorter. A Simulink IEEE 802.11a OFDM Transceiver system was used to demonstrate validity of the proposed pre-distorter. To the best of authors’ knowledge, this study presented excellent results of predistortion system that compensated the nonlinearity behaviour of the balanced RF power amplifier using the Simulink version R2011a.
