How to foster innovation in SMEs: evidence of the effectiveness of a project-based technology transfer approach

One of the main challenges in technology transfer is to actively involve small and medium-sized enterprises (SMEs)—which are most in need of and benefit the most from collaborative Research and Development (R&D) programs. This study presents a large-scale collaboration program which focuses on project-based technology transfer in SMEs with little to no prior experience in collaborative research projects. The core of this collaboration program is the temporary secondment of scientists from a Research and Technology Organization (RTO) into an SME to jointly work on a practical project objective—which is directly tailored to the demands of the SME. To evaluate the effectiveness of this approach in overcoming barriers related to finding the right collaboration partner, limited resources, and limited absorptive capabilities, we adopt the R&D Lifecycle Model as a theoretical framework. Our findings, using self-reported and objective data from 106 different projects in a structural equation model, highlight that most SMEs in the considered cluster environment not only successfully mastered a challenging topic in the context of industry 4.0 that immediately benefits the organization, but also engaged in new R&D projects to strengthen their scientific and technical human capital in the long term. Moreover, consistent with previous literature, we found that trust is the main driver within the R&D Lifecycle Model both in building capabilities and economic growth. Based on these insights, we consider a long and close secondment of scientists to SMEs as key for collaboration projects and discuss implications for research and future technology transfer approaches.

Digital Technologies for Children and Parents Sharing Self-Management in Childhood Chronic or Long-Term Conditions: A Scoping Review

Worldwide, the prevalence of chronic (or long-term) conditions in children and young people from birth to 18 years (children) is increasing. Promoting competent and effective self-management skills early in the trajectory is important to improve adherence to treatment and optimise quality of life. Successful self-management, therefore, requires parents and children who are developmentally able to develop a range of complex skills, including the use of digital technologies. This scoping review aimed to identify primary research investigating digital technologies for children and parents sharing self-management in childhood chronic illnesses. A comprehensive search of electronic databases was conducted. Nineteen papers were included, assessed for quality and methodological rigour using the Hawker tool and thematically analysed. Three themes were identified: (i) the feasibility and acceptability of using technology, (ii) the usability of technologies and (iii) the effect of technologies on adherence and self-management skills. The results indicate that technologies such as mobile apps and websites can assist the management of long-term conditions, are an acceptable method of delivering information and can promote the development of effective self-management skills by parents and children. However, future technology design must include children and parents in all stages of development.

Technology Solutions for Everyday Barriers Among Deaf Older Adults

American Sign Language (ASL) is the primary form of communication for approximately 250,000 people in the U.S. (Mitchell et al., 2006). As these individuals age, they may experience challenges in their everyday activities. For example, ASL users rely on visual cues, but have age-related change in vision. Moreover, ASL users may need to utilize technology to communicate with non-ASL users, but the technology may not be suitable/usable for older adults. We explored these issues in the Aging Concerns, Challenges, and Everyday Solution Strategies (ACCESS) study, wherein we interviewed Deaf older adults (N=60) in ASL, who provided insights into unique, everyday challenges they encounter. We will focus on the technology solution strategies they incorporate to address and overcome challenges with daily activities. Understanding how participants think about, adapt, and utilize different technologies can inform future technology design to successfully support diverse, aging populations.

Research and Implementation of Real-time Render Optimization Algorithm Based on GPU

In the continuous optimization of computer graphics, game engine and virtual reality have become the focus of research and innovation in the current technology field. Rendering is a core technology to show a variety of graphic effects, which has been attached great importance to and applied by the whole society. Nowadays, although the rendering of large-scale and complex scenes has a wide range of applications, the actual optimization requirements are very high. Therefore, in the future technology application and research and development, based on higher and higher technical requirements, it is necessary to improve the efficiency of actual rendering while ensuring or improving the rendering quality. Therefore, this paper studies how to use the algorithm to improve the efficiency of actual rendering, so as to provide a new basis for future computer graphics research.

Performance analysis of nanowire and nanosheet NCFETs for future technology nodes

Negative capacitance (NC) effect in nanowire (NW) and nanosheet (NS) field effect transistors (FETs) provide the much-needed voltage scaling in future technology nodes. Here, we present a comparative analysis on the performance of NC-NWFETs and NC-NSFETs through fully calibrated, three-dimensional computer aided design (TCAD) simulations. In addition to single channel NC-NSFETs and NC-NWFETs, those, with vertically stacked NSs and NWs, have been examined for the same layout footprint (LF). Results show that NC-NSFETs can achieve lower subthreshold swing (SS) and higher ON-current (ION ) than NC-NWFET of comparable device dimensions. However, NC-NWFETs show slightly higher ION/IOFF ratio. Negative differential resistance (NDR) is found to be more pronounced in NC-NSFET, enabling these devices to attain a stronger drain-induced-barrier-rising (DIBR) and steeper SS for gate lengths as small as 10 nm. The results presented here can, therefore, provide useful insights for performance optimization of NC-NWFETs and NC-NSFETs, in ultra-scaled and high-density logic applications, for 7 nm and beyond technology nodes.

Assessment of promising areas of digital livestock farming in the framework of "Agriculture 4.0"

Digital innovation is increasingly being promoted as a practice that allows producers to tackle the challenges of reducing the impact of livestock on greenhouse gas emissions, meeting the growing needs of the population, and the welfare of animals and the environment. Today, digital technologies are being implemented in the livestock sector in different ways: automation technologies are popular among farmers, and not technologies for collecting or processing data for decision-making. There is a risk that, with a focus on the future, technology development will focus on livestock in corporate, large-scale industrial production and therefore will not address the barriers to integrated digital solutions development and access for smallholder farmers. If so, Agriculture 4.0 will play a more limited role in making food systems sustainable. Agriculture 4.0 developers must focus not only on developing the latest sensor or device, but on a more holistic perspective, including consideration of regulatory requirements, business model, recommendations and capacity development, to ensure implementation and ensure the sharing of the benefits of Agriculture 4.0 for all participants in the agricultural sector.

p-Type Trigate Junctionless Nanosheet MOSFET: Analog/RF, Linearity, and Circuit Analysis

Silicon (Si) nanosheet (NS) metal-oxide semiconductor field effect transistors (MOSFETs) are realized as an outstanding structure to obtain better area scaling and power performance compared to FinFETs. Si NS MOSFETs provide high current drivability due to wider effective channel (Weff) and maintain better short channel performance. Here, the performance of junctionless (JL) NS p-MOSFET was evaluated by invoking HfxTi1-xO2 gate stack. The device performance was enhanced using various spacer dielectrics and the electrical characteristics are presented. Moreover, the effect of NS width variation on ION/IOFF, SS, Vth is presented and the analog/RF metrics of the device are evaluated. The power analysis of NS MOSFET is presented with respect to the ITRS road map. Our investigation reveals that the device exhibits an ION/IOFF ratio of more than ~106 with NS widths of 10 to 30 nm, respectively. For high-performance applications, the device exhibits better performance (ION) with higher NS widths. However, the threshold voltage downfall leads to deterioration in subthreshold performance with an increase in NS widths. With Si3N4 as a spacer dielectric the device exhibits better static power consumption for the CMOS inverter. By careful control of NS width and effective usage of spacer dielectric ensures better p-MOSFET design for future technology nodes.
