Extending existential feeling through sensory substitution
2023
AbstractIn current philosophy of mind, there is lively debate over whether emotions, moods, and other affects can extend to comprise elements beyond one’s organismic boundaries. At the same time, there has been growing interest in the nature and significance of so-called existential feelings, which, as the term suggests, are feelings of one’s overall being in the world. In this article, I bring these two strands of investigation together to ask: can the material underpinnings of existential feelings extend beyond one’s skull and skin? To begin, I introduce and adopt a componential-systemic view of extended affectivity. In doing so, I specify the vehicle externalist criteria for extension em…
Mākslinieciskās izteiksmes līdzekļi mazumtirdzniecības nozares rakstos
2020
Šajā darbā tiek pētīta mākslinieciskās izteiksmes līdzekļu izmantošana mazumtirdzniecības nozares rakstos. Pētījuma mērķis ir noskaidrot, vai biznesa žurnāla Forbes autori, izskaidrojot vienu izplatītu mazumtirdzniecības tēmu, mēdz izmantot mākslinieciskās izteiksmes līdzekļus savos rakstos, kā arī atklāt galvenos mērķus mākslinieciskās izteiksmes līdzekļu izmantošanai tajos. Pētījuma metode bija diskursa analīze kopā ar biežuma analīzi, izmantojot kvalitatīvo pieeju, īstenojot Skrebņeva klasifikāciju (2003). Analīze parādīja, ka šajos rakstos tika izmantoti daudzi dažādi mākslinieciskās izteiksmes līdzekļi; atkārtošana un anafora bija kopīgas visiem rakstiem. Autori mēdz izmantot mākslinie…
About the Horrific Peril of Reading on Digital Devices
2015
Abstract Reading on digital devices has become a widely debated issue in mass media and academia. The dawn and consolidation of digital technology have made possible new devices for reading. In the Internet era, reading is not just a matter of books and paper. This loss of exclusiveness has generated different anxieties in many intellectuals, researchers, journalists, editors, and publishers related to the printing environment. An analysis of such uneasiness can provide clues about the hidden interests and misunderstandings implied in their arguments. Revealing anxious claims about digital devices can enlighten us about the multiple factors and interests involved in the act of reading.
AUGMENTATIVE AND ALTERNATIVE COMMUNICATION (AAC) IN NEURODEVELOPMENTAL DISORDERS: A MINIREVIEW
2018
Children with neurodevelopmental disorders such as Autism Spectrum Disorders (ASD), cerebral palsy or severe motor speech disorders may beneficiate of augmentative and alternative communication (AAC) systems that may improve the developing language and the communication abilities. The term AAC tend to include each form of communication supplementing or replacing the natural speech production.
Preparation and characterisation of optical and optoelectronic devices based in two-dimensional semiconductors
2020
In the Materials Science field, two-dimensional materials have gained the scientific community attention in recent years. The change and the appearance of novel properties when their thickness is reduced to nanometric scale has special interest for its fundamental properties study for, from this base, the design and its implementation in devices. The wide variety of materials with the possibility of being exfoliated at the two-dimensional level opens the field to different applications, from optoelectronic devices, detection and sensing, energy storage, catalysis, medical applications and quantum information technologies, among others. This thesis gathers results in both directions: a funda…
Recent Advances in Drug Delivery from the Oral Cavity. Focus on innovative buccal drug delivery devices
2011
In this report, the drug administration via the oral cavity is discussed. Regional variations in oral mucosae, drug delivery via the keratinised mucosae for local treatment, and drug delivery via the not keratinised mucosae for local and systemic treatments are analyzed, focusing on Buccal drug delivery devices. Finally the IntelliDrug Device is presented as a revolutionary delivery system.
Preliminary test on a cascode switch for high-frequency applications
2020
Nowadays, an increasing electrification level is being addressed towards different sectors, such as transportation and industrial electronics. To bear that, high speed electrical machines represent a mature technology in different application fields, e.g. avionics, automotive, compressors and spindles. In order to guarantee high speed while keeping high power quality without adopting bulky filtering circuits, DC-AC converters shall be controlled by means of high Pulse Width Modulation (PWM) frequencies. In addition to the emerging switching device technologies, such as those based on Silicon-Carbide (SiC) and Gallium-Nitride (GaN), alternative circuital topologies are crucial in order to co…
Face Processing on Low-Power Devices
2009
The research on embedded vision-based techniques is considered nowadays as one of the most interesting matters of computer vision. In this work we address the scenario in which a real-time face processing system is needed to monitor people walking through some locations. Some face detection (e.g., Viola-Jones face detector) and face recognition (e.g., eigenfaces) approaches have reached a certain level of maturity, so we focused on the development of such techniques on embedded systems taking into account both hardware and software constraints. Our goal is to detect the presence of some known individuals inside some sensitive areas producing a compact description of the observed people. Cap…
The methodology for active testing of electronic devices under the radiations
2018
The methodology, developed for active testing of electronic devices under the radiations, is presented. The test set-up includes a gamma-ray facility, the hardware board/fixtures and the software tools purposely designed and realized. The methodology is so wide-ranging to allow us the verification of different classes of electronic devices, even if only application examples for static random access memory modules are reported.
A wireless battery charger architecture for consumer electronics
2012
In this paper, an innovative design of a wireless battery charger for portable electronic devices is proposed. The wireless power transfer is implemented through the magnetic coupling between a power transmitter, which is connected to the grid, and a power receiver, which is integrated inside the load device. An innovative receiver architecture which heavily improves the power conversion efficiency is presented. The proposed solution is standard compliant and suitable for IC implementation. A comparison between a conventional and the proposed receiver architectures is carried out by SPICE simulations. As shown by simulation results, a power efficiency increase by 40% is provided by the prop…
