No other area shows such a potential for disruption as digital platforms. B2C platforms, like Amazon and Uber, have radically changed the market situations within their industry. Until today, this change has mainly taken place in the B2C sector. Still, first platforms are already established in the B2B sector. Examples are Adamos in manufacturing and 365FarmNet in agriculture. With the entrance into the platform economy, companies are confronted with huge challenges. One question is whether a platform can be established in a certain industry due to its specific characteristics. Further questions are how a promising overall platform concept looks like, what relevant platform services are and who the essential actors on the platform are. In literature, there are different approaches for describing the benefits of a platform and designing a basic platform setup. Examples are the Platform Design Toolkit and Platform Value Canvas, which can be used for describing a platforms value proposition. Another example is the Platform Shell Model to describe the stakeholders of a platform. Still, those methods do not help companies to create a basis for decision-making for a platform strategy. In this paper we present a method for developing and evaluating concepts of a digital platform. Based on our project experience, we derived a thorough procedure complemented with adequate methods to do so. The starting point is the question of how a company should act regarding platforms in a certain industry. The goal is to develop platform concepts and to provide an initial evaluation. All relevant actors of an industry and their pains and gains should be considered. The platform concepts are based on the assumption that a platform can be described by its services and actors. The services should also be bundled into clusters with regard to their synergies in order to obtain consistent concepts. The validation shows that different platform concepts are promising depending on the ecosystem.

A recommendation system for energy saving and user engagement in existing buildings

引用

Proceedings of the Institution of Civil Engineers: Smart Infrastructure and Construction 2022年第1期176卷 1-11页

Ranked as the major energy-consuming sector, the building industry continuously introduces enhanced energy-management systems towards more energy efficiency. Despite technological progress, high amounts of resources are still wasted worldwide due to the wrong usage of energy systems in existing building stock. As a response, this paper proposes a recommendation system that is based on information and communication technologies and that provides building users with hands-on executable recommendations to reduce their energy consumption. Indeed, because of their lack of energy awareness and knowledge, people may need guidance in their daily usage of a building to change their energy behaviour and to save energy. For that purpose, the recommendation system analyses building operation data in real time to identify energy wastes as well as suitable energy conservation measures that shall help in saving energy. One main challenge is to provide a highly scalable solution that can be easily applied in a wider range of buildings, thus enabling resource saving at a large scale or even worldwide. For that purpose, the system relies on a model-based expert system for easy adaptation in any building regardless of its type, size and usage. © 2023 Published with permission by the ICE under the CC-BY 4.0 license.

Process Variations and Probabilistic Integrated Circuit Design

引用

2011年

作者： Manfred Dietrich, Joachim Haase

ISBN: (纸本)144196620X

Uncertainty in key parameters within a chip and between different chips in the deep sub micron area plays a more and more important role. As a result, manufacturing process spreads need to be considered during the design process. Quantitative methodology is needed to ensure faultless functionality, despite existing process variations within given bounds, during product development. This book presents the technological, physical, and mathematical fundamentals for a design paradigm shift, from a deterministic process to a probability-orientated design process for microelectronic circuits. Readers will learn to evaluate the different sources of variations in the design flow in order to establish different design variants, while applying appropriate methods and tools to evaluate and optimize their design.

Lab-on-a-chip systems are increasingly applied in cell-based assays for toxicology and drug testing. In this paper, an on-chip integrated lensless microscopy module using a direct projection method for optical monitoring of the shadow images of adherent growing mammalian cells is presented. The biological cells are conserved and interfaced by a microfabricated cavity chip with a 1 mu m thick silicon nitride (Si(3)N(4)) substrate onto the surface of a 5 megapixel CMOS image sensor with 2.2 mu m pixel size. The optical resolution of the assembly is estimated by the contact/proximate printing theory from optical lithography. Further characterization is made by imaging microbeads in chips with the Si(3)N(4)-membrane as well as in cavity chips with membranes made from dry film resist (DFR, thickness 20, 40 and 60 mu m). The module represents a 3 x optical microscope for cell morphology imaging. The function is demonstrated by the growth monitoring of L929 cells cultured in cavity chips with Si(3)N(4) substrate for 2 days and by checking the colorimetric staining of cells with a compromised membrane.

The documentation landscape for nursing care data in Germany is predominantly heterogeneous and unstructured. Therefore, insightful methods such as Artificial Intelligence (AI) are difficult to implement. We propose a stepwiseapproach that identifies relevant information from nursing theory and practice and maps it to a standardized nursing core data set to enable data-based improvement of nursing care. This can be used for various use-cases in care, such as risk detection and prevention in diverse care contexts. Many care processes can benefit of a cross-facility and standardized repository and associated applications. We propose an approach that enables the use of AI while leveraging consensus and evidenced-based expert knowledge from nursing science. © 2023 the author(s), published by Walter de Gruyter Berlin/Boston.

SENSORS AND ACTUATORS A-PHYSICAL 1997年第1-3期60卷 240-243页

作者： Stieglitz, T Beutel, H Meyer, JU Fraunhofer Institute for Biomedical Engineering Department of Sensor Systems/Microsystems Ensheimer-Straße 48 D-66386 St. Ingbert Germany

It has been shown previously that peripheral nerve axons regenerate through microvias in silicon devices, A major challenge in the design of a biocompatible interface is to establish a reliable electrical and mechanical interconnection to signal-processing and transmission electronics which allows simultaneous multichannel recordings or stimulation of nerves, This paper describes the on-going work of developing a new generation of flexible and extremely light-weight electrode arrays with integrated cables. A process technology has been established to fabricate a multilayer device with micromachining methods, which overcomes the 'classical' separation of substrate and insulation layers, The micromachined electrodes exhibit promising mechanical stability and high insulation resistance.

This book is dedicated to Prof. Dr. Heinz Gerhuser on the occasion of his retirement both from the position of Executive Director of the fraunhofer institute for Integrated Circuits IIS and from the Endowed Chair of Information Technologies with a Focus on Communication Electronics (LIKE) at the Friedrich-Alexander-Universitt Erlangen-Nrnberg. Heinz Gerhuser's vision and entrepreneurial spirit have made the fraunhofer IIS one of the most successful and renowned German research institutions. He has been Director of the fraunhofer IIS since 1993, and under his leadership it has grown to become the largest of Germany's 60 fraunhofer institutes, a position it retains to this day, currently employing over 730 staff. Likely his most important scientific as well as application-related contribution was his pivotal role in the development of the mp3 format, which would later become a worldwide success. The contributions to this Festschrift were written by both fraunhofer IIS staff and external project team members in appreciation of Prof. Dr. Gerhuser's lifetime academic achievements and his inspiring leadership at the fraunhofer IIS. The papers reflect the broad spectrum of the institute's research activities and are grouped into sections on circuits, information systems, visual computing, and audio and multimedia. They provide academic and industrial researchers in fields like signal processing, sensor networks, microelectronics, and integrated circuits with an up-to-date overview of research results that have a huge potential for cutting-edge industrial applications.

Today’s sensor applications show a rising demand on miniaturized autonomous sensors nodes with extreme requirements on power dissipation. One core functionality of these sensor nodes is the conversion of analog sensor signals to digital data for post processing and data communication. In this work a 11 bit Successive Approximation Register (SAR) ADC with minimized power dissipation is developed for a modern 22 nm FD-SOI technology. The design takes advantage of analog body biasing feature of FD-SOI technology. It achieves a power dissipation of 5 µW at a sampling rate of 100 kS/sec with an ENOB of 10 bit and 8.6 bit with and without calibration, respectively. The ADC design is flexible and easy to migrate among SOI technology nodes due to the use of generator-based Intelligent IP technology. © VDE VERLAG GMBH ∙ Berlin ∙ Offenbach

The Zero-Power Signal Conditioning IP (ZeSCIP) aims to operate in an autonomous environmental sensor node with energy harvester-extended life time. In this application, the sensor analog frontend has to process environmental signals of different nature, while it is confronted with power and space limitations and low operating voltages. In a flexible modular setup, the ZeSCIP analog frontend is attached to commercial sensors, which represent a specific air quality sensing scenario. This multi-sensor module is stacked to an ARM Cortex M4-based STM32 Nucleo™ board, creating an operational test setup of a modular sensor node, controlled via USB link. In measurement, the module consumes only 35.5\ μ W during processing of light, CO gas and temperature sensor signals, which makes it suitable to be autonomously powered by energy harvesters. © 2020 IEEE.
