Soundscape in Urban Forests
This Special Issue of Forests explores the role of soundscapes in urban forested areas. It is comprised of 11 papers involving soundscape studies conducted in urban forests from Asia and Africa. This collection contains six research fields: (1) the ecological patterns and processes of forest soundscapes; (2) the boundary effects and perceptual topology; (3) natural soundscapes and human health; (4) the experience of multi-sensory interactions; (5) environmental behavior and cognitive disposition; and (6) soundscape resource management in forests
Imagining & Sensing: Understanding and Extending the Vocalist-Voice Relationship Through Biosignal Feedback
The voice is body and instrument. Third-person interpretation of the voice by listeners, vocal teachers, and digital agents is centred largely around audio feedback. For a vocalist, physical feedback from within the body provides an additional interaction. The vocalist’s understanding of their multi-sensory experiences is through tacit knowledge of the body. This knowledge is difficult to articulate, yet awareness and control of the body are innate. In the ever-increasing emergence of technology which quantifies or interprets physiological processes, we must remain conscious also of embodiment and human perception of these processes. Focusing on the vocalist-voice relationship, this thesis expands knowledge of human interaction and how technology influences our perception of our bodies. To unite these different perspectives in the vocal context, I draw on mixed methods from cog- nitive science, psychology, music information retrieval, and interactive system design. Objective methods such as vocal audio analysis provide a third-person observation. Subjective practices such as micro-phenomenology capture the experiential, first-person perspectives of the vocalists them- selves. Quantitative-qualitative blend provides details not only on novel interaction, but also an understanding of how technology influences existing understanding of the body. I worked with vocalists to understand how they use their voice through abstract representations, use mental imagery to adapt to altered auditory feedback, and teach fundamental practice to others. Vocalists use multi-modal imagery, for instance understanding physical sensations through auditory sensations. The understanding of the voice exists in a pre-linguistic representation which draws on embodied knowledge and lived experience from outside contexts. I developed a novel vocal interaction method which uses measurement of laryngeal muscular activations through surface electromyography. Biofeedback was presented to vocalists through soni- fication. Acting as an indicator of vocal activity for both conscious and unconscious gestures, this feedback allowed vocalists to explore their movement through sound. This formed new perceptions but also questioned existing understanding of the body. The thesis also uncovers ways in which vocalists are in control and controlled by, work with and against their bodies, and feel as a single entity at times and totally separate entities at others. I conclude this thesis by demonstrating a nuanced account of human interaction and perception of the body through vocal practice, as an example of how technological intervention enables exploration and influence over embodied understanding. This further highlights the need for understanding of the human experience in embodied interaction, rather than solely on digital interpretation, when introducing technology into these relationships
Trends in Science and Technology for Sustainable Living
Dalam buku ini, dibahas mengenai perkembangan tren
kajian dalam sains dan teknologi yang mendukung pembangunan
berkelanjutan untuk mewujudkan kehidupan berkelanjutan.
Pembangunan berkelanjutan mempunyai prinsip pembangunan
yang bertujuan memenuhi kebutuhan generasi saat ini tetapi
tidak mengurangi ataupun mengorbankan kemampuan generasi
selanjutnya dalam memenuhi kebutuhan mereka; sehingga
kehidupan yang baik akan terus berlanjut dalam waktu yang
lama. Pembangunan berkelanjutan saat ini berfokus pada tiga
hal, yaitu pembangunan keberlanjutan ekonomi dan sosial, serta perlindungan terhadap lingkungan untuk generasi mendatang.
Ketiganya saling berhubungan dan mendukung dalam mencapai
tujuan pembangunan serta stabilitas lingkungan dan sosial. Oleh karena itu, keseimbangan yang baik dalam aspek lingkungan,ekonomi, dan sosial harus dicapai untuk membentuk kehidupan berkelanjutan

Modeling Deception for Cyber Security
In the era of software-intensive, smart and connected systems, the growing power and so-
phistication of cyber attacks poses increasing challenges to software security. The reactive
posture of traditional security mechanisms, such as anti-virus and intrusion detection
systems, has not been sufficient to combat a wide range of advanced persistent threats
that currently jeopardize systems operation. To mitigate these extant threats, more ac-
tive defensive approaches are necessary. Such approaches rely on the concept of actively
hindering and deceiving attackers. Deceptive techniques allow for additional defense by
thwarting attackers’ advances through the manipulation of their perceptions. Manipu-
lation is achieved through the use of deceitful responses, feints, misdirection, and other
falsehoods in a system. Of course, such deception mechanisms may result in side-effects
that must be handled. Current methods for planning deception chiefly portray attempts
to bridge military deception to cyber deception, providing only high-level instructions
that largely ignore deception as part of the software security development life cycle. Con-
sequently, little practical guidance is provided on how to engineering deception-based
techniques for defense. This PhD thesis contributes with a systematic approach to specify
and design cyber deception requirements, tactics, and strategies. This deception approach
consists of (i) a multi-paradigm modeling for representing deception requirements, tac-
tics, and strategies, (ii) a reference architecture to support the integration of deception
strategies into system operation, and (iii) a method to guide engineers in deception mod-
eling. A tool prototype, a case study, and an experimental evaluation show encouraging
results for the application of the approach in practice. Finally, a conceptual coverage map-
ping was developed to assess the expressivity of the deception modeling language created.Na era digital o crescente poder e sofisticação dos ataques cibernéticos apresenta constan-
tes desafios para a segurança do software. A postura reativa dos mecanismos tradicionais
de segurança, como os sistemas antivírus e de detecção de intrusão, não têm sido suficien-
tes para combater a ampla gama de ameaças que comprometem a operação dos sistemas
de software actuais. Para mitigar estas ameaças são necessárias abordagens ativas de
defesa. Tais abordagens baseiam-se na ideia de adicionar mecanismos para enganar os
adversários (do inglês deception). As técnicas de enganação (em português, "ato ou efeito
de enganar, de induzir em erro; artimanha usada para iludir") contribuem para a defesa
frustrando o avanço dos atacantes por manipulação das suas perceções. A manipula-
ção é conseguida através de respostas enganadoras, de "fintas", ou indicações erróneas
e outras falsidades adicionadas intencionalmente num sistema. É claro que esses meca-
nismos de enganação podem resultar em efeitos colaterais que devem ser tratados. Os
métodos atuais usados para enganar um atacante inspiram-se fundamentalmente nas
técnicas da área militar, fornecendo apenas instruções de alto nível que ignoram, em
grande parte, a enganação como parte do ciclo de vida do desenvolvimento de software
seguro. Consequentemente, há poucas referências práticas em como gerar técnicas de
defesa baseadas em enganação. Esta tese de doutoramento contribui com uma aborda-
gem sistemática para especificar e desenhar requisitos, táticas e estratégias de enganação
cibernéticas. Esta abordagem é composta por (i) uma modelação multi-paradigma para re-
presentar requisitos, táticas e estratégias de enganação, (ii) uma arquitetura de referência
para apoiar a integração de estratégias de enganação na operação dum sistema, e (iii) um
método para orientar os engenheiros na modelação de enganação. Uma ferramenta protó-
tipo, um estudo de caso e uma avaliação experimental mostram resultados encorajadores
para a aplicação da abordagem na prática. Finalmente, a expressividade da linguagem
de modelação de enganação é avaliada por um mapeamento de cobertura de conceitos
