Porous anodic alumina (PAA) has been intensively studied in past decade due to its applications for fabricating nanostructured materials. Since PAA's pore diameter, thickness and shape vary too much, a systematical study on the methods of morphology characterization is meaningful and essential for its proper development and utilization. In this paper, we present detailed AFM, SEM and TEM studie...

Adoption of service orientation in all aspects of enterprise computing has gained momentum in recent years. This paper describes research on Service-Oriented Infrastructure (SOI) and key concepts that enable higherlevel service orientation and autonomic computing. We demonstrate how the concept of platform as a service (PaaS) may be applied to a real Information Technology (IT) operational envi...

The environments of software development and software provision are shifting to Web-based platforms supported by Platform/Software as a Service (PaaS/SaaS) models. This paper will make the case that there is equally an opportunity for mobile operators to identify additional sources of revenue by exposing network functionalities through Web-based service platforms. By elaborating on the concepts...

Cloud technologies provide abilities for simple and reliable scaling of resources, due to which they have become widespread. The task managing distributed services in a cloud environment is especially relevant today. Special programs are used that purpose named “orchestrators” implement the functions lifecycle management applications. However, existing solutions many limitations not applicable ...

The wide adoption of the cloud computing paradigm plays a crucial role in the ever-increasing demand for energy-efficient data centers. Driven by this requirement, cloud providers resort to a variety of techniques to improve energy usage at each level of the cloud computing stack. However, prior studies mostly consider resource-level energy optimizations in IaaS clouds, overlooking the workload...

BigBench is the new standard (TPCx-BB) for benchmarking and testing Big Data systems. The TPCx-BB specification describes several business use cases —queries— which require a broad combination of data extraction techniques including SQL, Map/Reduce (M/R), user code (UDF), and Machine Learning to fulfill them. However, currently, there is no widespread knowledge of the different resource require...

Platform-as-a-service (PaaS) systems, such as Google App Engine (GAE), simplify web application development and cloud deployment by providing developers with complete software stacks: runtime systems and scalable services accessible from well-defined APIs. Extant PaaS offerings are designed and specialized to support large numbers of concurrently executing web applications (multi-tier programs ...

P ulmonary artery (PA) aneurysms (PAAs) are rare and infrequently diagnosed. Deterling and Clagett 1 discovered 8 cases of PAAs in 109 571 consecutive postmortem examinations. PAAs generally occurred in a younger age group than aortic aneurysms with an equal sex incidence. 2 Eighty-nine percent of all PAAs were located in the main PA, whereas only 11% were located in the pulmonary branches. 3 W...
