This paper focuses on service deployment optimization in cloud computing environments. In a cloud, an application is assumed to consist of multiple services. Each service in an application can be deployed as one or more service instances. Different service instances operate at different quality of service (QoS) levels depending on the amount of computing resources assigned to them. In order to ...

Infants require locomotor experience to behave adaptively at a drop-off. However, different experimental paradigms (visual cliff and actual gaps and slopes) have generated conflicting findings regarding what infants learn and the specificity of their learning. An actual, adjustable drop-off apparatus was used to investigate whether learning to distinguish a step from a cliff transfers from craw...

In embedded systems, efficient implementations of numerical algorithms typically use the fixed-point arithmetic rather than the standardized and costly floating-point arithmetic. But, fixed-point programmers face two difficulties: First, writing fixed-point codes is tedious and error prone. Second, the low dynamic range of fixed-point numbers leads to the persistent belief that fixedpoint compu...

PURPOSE Treatment planning for radiation therapy involves trade-offs with respect to different clinical goals. Typically, the dose distribution is evaluated based on few statistics and dose-volume histograms. Particularly for stereotactic treatments, the spatial dose distribution represents further criteria, e.g., when considering the gradient between subregions of volumes of interest. The auth...

‘‘Our land is sacred, and not tradable.’’ ‘‘Jerusalem is not up for discussion.’’ ‘‘As a matter of principle, I will not give that crook a dime!’’ ‘‘Human life cannot be given a dollar value.’’ Each of these statements suggests that the actor places a sacred value on some issue. But, what does sacred mean? One possible answer is that it is a constraint and that the issue is truly not open for d...

BACKGROUND There is an ongoing debate about the applicability of current criteria for large waist circumference (WC) in older adults. OBJECTIVES Our aim was to explore cut-off values for large WC in adults aged 70 years and older, using previously used and new methods. DESIGN Prospective cohort study. PARTICIPANTS Data of 1049 participants of the Longitudinal Aging Study Amsterdam (LASA) ...

Fuzzy sets theory affirmed that the linguistic value for every contraries relation is complementary. It was stressed in the intuitionistic fuzzy sets (IFS) that the conditions for contraries relations, which are the fuzzy values, cannot be greater than one. However, complementary in two contradict phenomena are not always true. This paper proposes a new idea condition for conflicting bifuzzy se...

Wireless camera sensor networks have to balance the conflicting challenges imposed by the detection performance, latency and lifetime requirements in surveillance applications. While previous studies for camera sensor networks have addressed these issues separately, they have not quantified the trade-offs between these requirements. In this paper, we discuss the design and implementation of SCO...

Abstract While the world was facing a rapidly progressing COVID-19 second wave, policy paradox emerged. On one side, much more known by Autumn 2020 about mechanisms underpinning spread and lethality of Sars-CoV-2. other how such knowledge should be translated policymakers into containment measures appeared to controversial debated than during first wave in Spring. Value-laden, conflicting views...
