Nowadays the competitive pressure increases, with the consequence that the differentiation from competitors by goods or services alone is no longer sufficient. For that reason, companies offer integrated bundles of tangible goods and services, which aim to solve a customer’s problem holistically. These bundles are known as Hybrid Products or Product Service Systems (PSS). In case of IT-enabled ...

Absfrad A neural network-based Power System Stabilizer (Neuro-PSS) is designed for a generator connected to a multimachine power system utilizing the nonlinear power flow dynamics. The uses of power flow dynamics provide a PSS for a wide range operation with reduced size neural networks. The Neuro-PSS consists of two neural networks: Neuro-Identifier and Neuro-Controller. The low-frequency osci...

In this paper we introduce the idea of probability in the definition of a Sequential Dynamical System (SDS), thus obtaining a new concept, that of Probabilistic Sequential System (PSS). Due to its particular dynamic, the Probabilistic Boolean Network (PBN) model has been applied to genetic regulatory networks. The model we introduce combines the sequential aspect of the SDSs and the dynamic of ...

The increasing entwinement of products and services in combined offers – so called Product-Service Systems (PSS) – leads to various requirements regarding the modelling of those systems. Due to these requirements, software support is needed for customer-specific configuration of complex PSS. To provide such software a formal description of the structure of products and services is required. Fur...

GaN films grown on PSS are investigated by XRD, CL, SEM and TEM. There are low threading dislocations (TDs) with larger fill factor, which results in better electrostatic discharge (ESD) yield of LEDs. The effect of growth rate on dislocations in GaN films grown on PSS is investigated by TEM. It is found that dislocations density decreases as the growth rates decrease. And the performance of In...

Research suggests that product service systems (PSS) may usefully form part of the mix of innovations necessary to move society toward more sustainable futures. However, PSS implementation rates are disappointingly low and an implementation gap has emerged. Drawing on consumer culture theory (CCT), this paper provides insights to help resolve this issue in business to consumer markets. Since co...

OBJECTIVE To characterize the ultrasound (US) pattern of joint involvement in primary Sjögren's syndrome (pSS). METHODS Seventeen patients with pSS, 18 with secondary Sjögren's syndrome (sSS), and 17 healthy controls underwent US examinations of various articular regions. Synovitis (synovial hypertrophy/joint effusion), power Doppler (PD) signals, and erosions were assessed. RESULTS In pati...

Product-Service Systems (PSSs) constitute a family of service-based business models designed to satisfy our societal needs in an economically and environmentally sustainable manner. To date however PSS application has remained niche due to a variety of critical barriers. This paper explores how ‘demand pull’ national government policies could support PSS activity by addressing these barriers an...

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease, characterized by lymphocytic infiltration of the secretory glands. This process leads to sicca syndrome, which is the combination of dryness of the eyes, oral cavity, pharynx, larynx and/or vagina. Extraglandular manifestations may also be prevalent in patients with pSS, including cutaneous, musculoskeletal, pulmonary, renal, he...

OBJECTIVE Munich Nomenclature III for cervical smear evaluation also known as Papanicolaou (Pap) smear was launched in Germany in July 2014, and it is the only used system in Germany. The study aims at a method comparison between the previously used nomenclature Munich II and the currently used Munich III. MATERIAL AND METHODS A method comparison was performed by analyzing 117 Pap smear sampl...
