Protection of islets in culture by delivery of oxygen binding neuroglobin via protein transduction.
2005
Islet transplantation has become an accepted method to treat type 1 diabetes. To succeed and achieve normal levels of glucose in transplant recipients, the quality of the transplanted islets is of the utmost importance. Lack of oxygen during organ procurement, islet isolation, and subsequent culture triggers apoptosis or necrosis and loss of islet function, causing the yield and quality to diminish. A promising candidate for cytoprotection against oxygen deprivation is neuroglobin (Ngb). Ngb is a recently described member of globin family and is expressed in neurons, retina, and pancreatic islets. To overexpress this protein in the islets and study its ability to protect them, we utilized p…
An Energy-Autonomous Wireless Sensor with Simultaneous Energy Harvesting and Ambient Light Sensing
2021
Wireless sensor nodes (WSNs) are generally powered by batteries, which results in a substantial limitation to the places where the nodes can be installed, to the maximum number of deployable devices, and to the node lifetime. To meet the demand for Internet-of-Things (IoT) applications that require a large number of maintenance-free, low cost, wireless sensor nodes, this paper proposes a wireless sensor platform with a single photovoltaic transducer that performs the dual role of harvesting energy and sensing ambient light. This dual use allows even smaller and cheaper nodes that do not require any form of supporting external power, with a reduced component count. The device implements off-…
A CUDA-based implementation of an improved SPH method on GPU
2021
We present a CUDA-based parallel implementation on GPU architecture of a modified version of the Smoothed Particle Hydrodynamics (SPH) method. This modified formulation exploits a strategy based on the Taylor series expansion, which simultaneously improves the approximation of a function and its derivatives with respect to the standard formulation. The improvement in accuracy comes at the cost of an additional computational effort. The computational demand becomes increasingly crucial as problem size increases but can be addressed by employing fast summations in a parallel computational scheme. The experimental analysis showed that our parallel implementation significantly reduces the runti…
Humans and Their Technologies Play the Infinite Game
2019
Technology is increasingly about intuitive use and automation, as is evident to some degree in all the papers published in this issue. Technological--and one could say, even civilizational--progress is made possible by automating necessary but often tedious and tiresome processes. This then frees people's time and energy for a variety of recreational, inspirational, and/or developmental tasks. However, as the automation of society advances, the meaning of work changes and new existential and ethical questions emerge. nonPeerReviewed
Density flow over networks: A mean-field game theoretic approach
2014
A distributed routing control algorithm for dynamic networks has recently been presented in the literature. The networks were modeled using time evolution of density at network edges and the routing control algorithm allowed edge density to converge to a Wardrop equilibrium, which was characterized by an equal traffic density on all used paths. We borrow the idea and rearrange the density model to recast the problem within the framework of mean-field games. The contribution of this paper is three-fold. First, we provide a mean-field game formulation of the problem at hand. Second, we illustrate an extended state space solution approach. Third, we study the stochastic case where the density …
Self in NARS, an AGI System
2018
This article describes and discusses the self-related mechanisms of a general-purpose intelligent system, NARS. This system is designed to be adaptive and to work with insufficient knowledge and resources. The system’s various cognitive functions are uniformly carried out by a central reasoning-learning process following a “non-axiomatic” logic. This logic captures the regularities of human empirical reasoning, where all beliefs are revisable according to evidence, and the meaning of concepts are grounded in the system’s experience. NARS perceives its internal environment basically in the same way as how it perceives its external environment although the sensors involved are completely diff…
AI ethics:an empirical study on the views of practitioners and lawmakers
2023
Artificial intelligence (AI) solutions and technologies are being increasingly adopted in smart systems contexts; however, such technologies are concerned with ethical uncertainties. Various guidelines, principles, and regulatory frameworks are designed to ensure that AI technologies adhere to ethical well-being. However, the implications of AI ethics principles and guidelines are still being debated. To further explore the significance of AI ethics principles and relevant challenges, we conducted a survey of 99 randomly selected representative AI practitioners and lawmakers (e.g., AI engineers and lawyers) from 20 countries across five continents. To the best of our knowledge, this is the …
Application of Heavy Equipment Telematics in Infrastructure Projects : Method for automating collection of mixed fleet data, and optimization of proj…
2019
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2019 Existing heavy equipment telematics capabilities are not being used to their potential.In collaboration with Skanska there is an interest to look at how telematics can beused more efficiently with mixed equipment fleets. Current and future aspects are com-pelling, especially in relations to optimization and environmental benefits.Rv. 3 /rv. 25Løten–Elverumis provided as a case.This master’s thesis takes a closer look at the use of telematics data from heavy equip-ment at infrastructure projects. Through the automation of collecting telematics data,mixed fleet data are juxtapositioned to give insight into …
Robots responding to care needs? : A multitasking care robot pursued for 25 years, available products offer simple entertainment and instrumental ass…
2020
Twenty-five years ago, robotics guru Joseph Engelberger had a mission to motivate research teams all over the world to design the ‘Elderly Care Giver’, a multitasking personal robot assistant for everyday care needs in old age. In this article, we discuss how this vision of omnipotent care robots has influenced the design strategies of care robotics, the development of R&D initiatives and ethics research on use of care robots. Despite the expectations of robots revolutionizing care of older people, the role of robots in human care has remained marginal. The value of world trade in service robots, including care robots, is rather small. We argue that the implementation of robots in care is n…
Automated Testing of iOS Apps: tTap Extension for Apple UIAutomation
2015
Mobile apps tend to extend or even substitute the existing IT solutions. In the corporate world, according to the statistics, the preference is given to iOS devices. The complexity of the apps increases together with the apps quantity. This also increases the need for automated testing. In a course of the study we compare the existing test automation solutions for iOS apps and describe some extensions for Apple UIAutomation tool. We have also created our own extension called tTap that improves the existing ones and solves several issues that does not work in the clean UIAutomation. We describe the implementation details of our extension and share the practical experience of testing iOS apps…
