Unternehmenskultur
(2022)
Unternehmenskultur als die zentrale informeller Steuerungsgröße von Organisationen spielt insbesondere bei der Verankerung ethischer Werte und Prinzipien in Unternehmen eine unverzichtbare Rolle. Warum dies so ist und welchen konkreten Beitrag eine bewusste Kulturentwicklung im Kontext angewandter Unternehmensethik leisten kann, ist Gegenstand des Artikels.
Unternehmensberatung
(2022)
Im Kapitel "Unternehmensberatung" geht es um die Themen, inhaltlichen Schwerpunkte und möglichen Ansätze von Beratungsdienstleistungen im Kontext heutiger angewandter Unternehmensethik. Von der Gestaltung einer Unternehmenskultur der Integrität zur Prävention von Wirtschaftskriminalität bis zur Entwicklung eines ganzheitlichen unternehmerischen Verantwortungsmanagements, das neben Nachhaltigkeitsaspekten auch einen ethisch reflektierten Umgang mit Digitalisierung und KI umfasst.
Because process and product innovations are usually no longer sufficient to establish a company in the market or to generate a competitive advantage, Business Model Innovation is considered a powerful tool, especially for start-ups for which innovation is at the core of their business. Due to the complexity of this process, frameworks should help entrepreneurs with executing Business Model Innovation. However, theory and practice diverge. The aim of this paper is to identify the needs of a start-up regarding Business Model Innovation frameworks, underlining the importance of Business Model Innovation for start-ups as well as the relevance of a supporting framework. The research results aim to contribute to an ideal process for Business Model Innovation when applied to start-ups.
Feature-Based Proposal Density Optimization for Nonlinear Model Predictive Path Integral Control
(2022)
This paper presents a novel feature-based sampling strategy for nonlinear Model Predictive Path Integral (MPPI) control. In MPPI control, the optimal control is calculated by solving a stochastic optimal control problem online using the weighted inference of stochastic trajectories. While the algorithm can be excellently parallelized the closed- loop performance is dependent on the information quality of the drawn samples. Because these samples are drawn using a proposal density, its quality is crucial for the solver and thus the controller performance. In classical MPPI control, the explored state-space is strongly constrained by assumptions that refer to the control value variance, which are necessary for transforming the Hamilton-Jacobi-Bellman (HJB) equation into a linear second-order partial differential equation. To achieve excellent performance even with discontinuous cost-functions, in this novel approach, knowledge-based features are used to determine the proposal density and thus, the region of state- space for exploration. This paper addresses the question of how the performance of the MPPI algorithm can be improved using a feature-based mixture of base densities. Further, the developed algorithm is applied on an autonomous vessel that follows a track and concurrently avoids collisions using an emergency braking feature.
Das erfolgreiche Gestalten von Organisationen setzt die systematische Analyse ihrer Prozesse voraus. Das gilt auch und insbesondere für kleine und mittelgroße Unternehmen (KMU). Die praktische Durchführung solcher in KMU ist jedoch mit besonderen Herausforderungen verbunden, die in der vorhandenen Literatur bislang kaum reflektiert werden. In diesem Beitrag werden Erfahrungen aus 20 in KMU durchgeführten Prozessanalysen geteilt. Entlang der Prozessphasen werden unterschiedliche Gestaltungsmöglichkeiten vorgestellt und ihre spezifischen Vor- und Nachteile bei der praktischen Anwendung in KMU identifiziert. Der Beitrag unterstreicht die Relevanz von Prozessanalysen in KMU und befähigt zugleich zu ihrer Durchführung.
Personalized remote healthcare monitoring is in continuous development due to the technology improvements of sensors and wearable electronic systems. A state of the art of research works on wearable sensors for healthcare applications is presented in this work. Furthermore, a state of the art of wearable devices, chest and wrist band and smartwatches available on the market for health and sport monitoring is presented in this paper. Many activity trackers are commercially available. The prices are continuously reducing and the performances are improving, but commercial devices do not provide raw data and are therefore not useful for research purposes.
Gamification is one of the recognized methods of motivating people in various life processes, and it has spread to many spheres of life, including healthcare. This article proposes a system design for long-term care patients using the method mentioned. The proposed system aims to increase patient engagement in the treatment and rehabilitation process via gamification. Literature research on available and earlier proposed systems was conducted to develop a suited system design. The primary target group includes bedridden patients and a sedentary lifestyle (predominantly lying in bed). One of the main criteria for selecting a suitable option was its contactless realization for the mentioned target groups in long-term care cases. As a result, we developed the system design for hardware and software that could prevent bedsores and other health problems from occurring because of low activity. The proposed design can be tested in hospitals, nursing homes, and rehabilitation centers.
In recent decades, it can be observed that a steady increase in the volume of tourism is a stable trend. To offer travel opportunities to all groups, it is also necessary to prepare offers for people in need of long-term care or people with disabilities. One of the ways to improve accessibility could be digital technologies, which could help in planning as well as in carrying out trips. In the work presented, a study of barriers was first conducted, which led to selecting technologies for a test setup after analysis. The main focus was on a mobile app with travel information and 360° tours. The evaluation results showed that both technologies could increase accessibility, but some essential aspects (such as usability, completeness, relevance, etc.) need to be considered when implementing them.
The digital twin concept has been widely known for asset monitoring in the industry for a long time. A clear example is the automotive industry. Recently, there has also been significant interest in the application of digital twins in healthcare, especially in genomics in what is known as precision medicine. This work focuses on another medical speciality where digital twins can be applied, sleep medicine. However, there is still great controversy about the fundamentals that constitute digital twins, such as what this concept is based on and how it can be included in healthcare effectively and sustainably. This article reviews digital twins and their role so far in what is known as personalized medicine. In addition, a series of steps will be exposed for a possible implementation of a digital twin for a patient suffering from sleep disorders. For this, artificial intelligence techniques, clinical data management, and possible solutions for explaining the results derived from artificial intelligence models will be addressed.
