    The paper assesses the performance of the technology licensing offices (TLO) and technology transfer offices (TTO) which have been active in Portuguese higher education institutions. Data stemming from a survey of these entities was analyzed in successive steps through factor analysis, cluster analysis and estimation of a model using the Partial-Least Squares methodology. It is shown that the institutional nature of each of the surveyed organizations implies different behaviours and outcomes. Further it has also became clear that the type of resources and activities in the surveyed organizations determine both their “primary outcome” (patent applications and technology transfer processes) and their “final outcome” (technology licensing contracts and technology-based spin-offs). The results of this paper might be particularly relevant for other similar economies as Portugal where high-tech and knowledge-intensive industries have not been dominant.technology transfer; university-industry relationships; university patenting; university spin-offs

    Ferroelectric switching is unambigiously demonstrated for the first time in a III-V semiconductor based material: AlScN -- A discovery which could help to satisfy the urgent demand for thin film ferroelectrics with high performance and good technological compatibility with generic semiconductor technology which arises from a multitude of memory, micro/nano-actuator and emerging applications based on controlling electrical polarization. The appearance of ferroelectricity in AlScN can be related to the continuous distortion of the original wurtzite-type crystal structure towards a layered-hexagonal structure with increasing Sc content and tensile strain, which is expected to be extendable to other III-nitride based solid solutions. Coercive fields which are systematically adjustable by more than 3 MV/cm, high remnant polarizations in excess of 100 \mu C/cm2^2 which constitute the first experimental estimate of the previously inaccessible spontaneous polarization in a III-nitride based material, an almost ideally square-like hysteresis resulting in excellent piezoelectric linearity over a wide strain interval from -0.3% to +0.4% as well as a paraelectric transition temperature in excess of 600{\deg}C are confirmed. This intriguing combination of properties is to our knowledge as of now unprecedented in the field of polycrystalline ferroelectric thin films and promises to significantly advance the commencing integration of ferroelectric functionality to micro- and nanotechnology, while at the same time providing substantial insight to one of the central open questions of the III-nitride semiconductors - that of their actual spontaneous polarization

    Technological advancement is rapidly changing our daily lives. Many teachers seek ways to implement technology to improve students’ learning experiences. How do we determine what types of technological tools to use to maximize learning? This research investigated the effectiveness of the integration of the Substitution Augmentation Substitution and Redefinition (SAMR) model and other web applications in learning Japanese at the high school level. Fifty-one students in first-year Japanese language classes participated in a technology-integrated lesson. Technology-enhanced activities were selected with the SAMR model and were developed for students to learn and demonstrate Japanese language skills and cultural knowledge in a learning sequence based on second language theories. A pre-survey, formative assessments, summative assessments, homework logs, a post survey, and a teacher journal were analyzed to determine the effectiveness of such integration and its influences on learners’ language performance and motivation. Results indicated that students’ language performance increased in both interpretive and presentational modes of communication, however, there was no significant improvement in the interpersonal mode of communication. In addition, students also developed learning strategies with technology as they shared them with their peers

    Integrating Form and Meaning: A Multi-Task Learning Model for Acoustic Word Embeddings

    Full text link
    Models of acoustic word embeddings (AWEs) learn to map variable-length spoken word segments onto fixed-dimensionality vector representations such that different acoustic exemplars of the same word are projected nearby in the embedding space. In addition to their speech technology applications, AWE models have been shown to predict human performance on a variety of auditory lexical processing tasks. Current AWE models are based on neural networks and trained in a bottom-up approach that integrates acoustic cues to build up a word representation given an acoustic or symbolic supervision signal. Therefore, these models do not leverage or capture high-level lexical knowledge during the learning process. In this paper, we propose a multi-task learning model that incorporates top-down lexical knowledge into the training procedure of AWEs. Our model learns a mapping between the acoustic input and a lexical representation that encodes high-level information such as word semantics in addition to bottom-up form-based supervision. We experiment with three languages and demonstrate that incorporating lexical knowledge improves the embedding space discriminability and encourages the model to better separate lexical categories.Comment: Accepted in INTERSPEECH 202

    A Wideband Inductorless CMOS Front-End for Software Defined

    The number of wireless communication links is witnessing tremendous growth and new standards are being introduced at high pace. These standards heavily rely on digital signal processing, making CMOS the first technology of choice. However, RF CMOS circuit development is costly and time consuming due to mask costs and design iterations. This pleads for a Software Defined Radio approach, in which one piece of flexible radio hardware is re-used for different applications and standards, downloadable and under software control. To the best of our knowledge, little work has been done in this field based on CMOS technology. Recently, a bipolar downconverter front-end has been proposed [1]. In CMOS, only wideband low-noise amplifiers have been proposed, and some CMOS tuner ICs for satellite reception (which have less stringent noise requirements because they are preceded by an outdoor low-noise converter). This paper presents a wideband RF downconverter frontend in 0.18 um CMOS (also published in [2]), designed in the context of a research project exploring the feasibility of software defined radio, using a combined Bluetooth/WLAN receiver as a vehicle. Usually, RF receivers are optimised for low power consumption. In contrast, we have taken the approach to optimise for flexibility. The paper discusses the main system and circuit design choices, and assesses the achievable performance via measurements on a front-end implemented in 0.18um CMOS. The flexible design achieves a 0.2-2.2 GHz -3 dB bandwidth, a gain of 25 dB with 6 dB noise figure and +1 dBm IIP3
