Principles of Elastic Processes

Schahram Dustdar, Yike Guo, Benjamin Satzger, Hong-Linh Truong
2011 IEEE Internet Computing  
The main issue here is to associate a service with a measurable quality and the cost function, which computes the resource requirement for a given quality, such as execution speed.  ...  In sensor networks, energy awareness is an essential property, and indeed a large body of research on energy-efficient sensor networks exists, mostly with a focus on routing, but also on energy-aware resource  ...

Predictive Policing and the Platformization of Police Work

Simon Egbert
2019 Surveillance & Society  
This paper argues that because of its enablement of crime data analysis in general, predictive policing software will be an important incubator for datafied police work, especially when executed via data  ...  mining platforms, because it has made police authorities aware that the massive amounts of crime data they possess are quite valuable and can now be easily analyzed.  ...  Surveillance &Society 17(1/2) By speaking of an inbuilt function creep, I rephrase an expression from Nikolaus Pöchhacker who introduced the notion of "scripted function creep" with reference to big  ...

However, despite broad acceptance, some of its properties have not been fully explored and thus not exploited, particularly for two common forms of multidimensional decomposition.  ...  ., transformation of massive datasets, appending data, approximation of data streams and partial data reconstruction, leading to significant I/O cost reduction in all cases.  ...  Note, that although the asymptotic cost is high, the required SHIFT-SPLIT operations are very fast, which leads to fast execution times for expanding the domain of one dimension.  ...

QoE4CLOUD: A QoE-driven multidimensional framework for cloud environments

Emmanouil Kafetzakis, Harilaos Koumaras, Michail Alexandros Kourtis, Vaios Koumaras
2012 2012 International Conference on Telecommunications and Multimedia (TEMU)  
The ultimate target of any intelligent cloud management scheme should be the provision of a service at an adequate quality level, creating the need to introduce the notion of Quality of Experience (QoE  ...  Similarly, both Service/Platform Providers and End-Users wish to avoid the extra cost of this over-provisioning tactic and pay only per use, without having to statically reserve extra resources in advance  ...  Therefore, the existing service architectures should be expanded to include the virtual resources, described in terms of properties and functionalities [20] .  ...

Vertical Indexing for Moving Objects in Multifloor Environments

Sultan Alamri, David Taniar, Kinh Nguyen
2018 Mobile Information Systems  
The GMI-tree is based on two notions of distance, or equivalently, two notions of adjacency: one represents horizontal adjacency and the other represents vertical adjacency.  ...  Secondly, the relevant notion of locations of an object is cell based rather than an exact Euclidean coordinate.  ...  Conflicts of Interest Sultan Alamri now works at the College of Computing and Informatics, SEU, Saudi Arabia. e authors declare that there are no conflicts of interest regarding the publication of this  ...
