    Real-time complexity constrained encoding

    Complex software appliances can be deployed on hardware with limited available computational resources. This computational boundary puts an additional constraint on software applications. This can be an issue for real-time applications with a fixed time constraint such as low delay video encoding. In the context of High Efficiency Video Coding (HEVC), a limited number of publications have focused on controlling the complexity of an HEVC video encoder. In this paper, a technique is proposed to control complexity by deciding between 2Nx2N merge mode and full encoding, at different Coding Unit (CU) depths. The technique is demonstrated in two encoders. The results demonstrate fast convergence to a given complexity threshold, and a limited loss in rate-distortion performance (on average 2.84% Bjontegaard delta rate for 40% complexity reduction)

    Job satisfaction in relation to communication in health care among nurses : a narrative review and pratical recommendations

    Get PDF
    Worldwide, nurse shortage and high turnover rates are observed. Job satisfaction is a major determinant of retention and is influenced by intraorganizational communication and perceived communication satisfaction. This article presents a narrative review on communication satisfaction, job satisfaction, and their mutual relationship as well as their impact on turnover intention and burnout risk in the nursing profession. A literature search was conducted in the databases PubMed, Web of Science, and The Cochrane Library, and 47 articles were included. Descriptive analysis identified different types of social networks in the health care workplace. There is a positive association between communication and job satisfaction among nurses, translating into decreased turnover intention and burnout risk. Job satisfaction is required both for organizational stability as for coguaranteeing patient safety. This will be best achieved through an organization-wide multimodal prevention and intervention program, aimed at optimizing different modalities of interprofessional communication, workload, and job satisfaction
