Detection of compound structures using a gaussian mixture model with spectral and spatial constraints
(Institute of Electrical and Electronics Engineers Inc., 2014)
Increasing spectral and spatial resolution of new-generation remotely sensed images necessitate the joint use of both types of information for detection and classification tasks. This paper describes a new approach for ...
Coordinated movement of multiple mobile sinks in a wireless sensor network for improved lifetime
(SpringerOpen, 2015)
Sink mobility is one of the most effective solutions for improving lifetime and has been widely investigated for the last decade. Algorithms for single-sink mobility are not directly applied to the multiple-sink case due ...
An O(n1/3) algorithm for distributed mutual exclusion
(Elsevier, 1998)
In this paper, a distributed algorithm is proposed that realizes mutual exclusion among n nodes in a computer network. No common or global memory is shared by the nodes and there is no global controller. The nodes of the ...
Processing real-time transactions in a replicated database system
(Springer/Kluwer Academic Publishers, 1994)
A database system supporting a real-time application has to provide real-time information to the executing transactions. Each real-time transaction is associated with a timing constraint, typically in the form of a deadline. ...
Verification of protocol conformance test cases using reachability analysis
(Elsevier Inc., 1992)
A methodology is presented to verify manually written test cases against the formal specification of a protocol. Initially, a protocol and a test case are modeled as nondeterministic finite state machines and test case ...
Efficient parallel spatial subdivision algorithm for object-based parallel ray tracing
(Pergamon Press, 1994)
Parallel ray tracing of complex scenes on multicomputers requires the distribution of both computation and scene data to the processors. This is carried out during preprocessing and usually consumes too much time and memory. ...
Network-aware virtual machine placement in cloud data centers with multiple traffic-intensive components
(Elsevier BV, 2015)
Following a shift from computing as a purchasable product to computing as a deliverable service to consumers over the Internet, cloud computing has emerged as a novel paradigm with an unprecedented success in turning utility ...
Research issues in real-time database systems . Survey paper
(Elsevier, 1995)
Today's real-time systems are characterized by managing large volumes of data. Efficient database management algorithms for accessing and manipulating data are required to satisfy timing constraints of supported applications. ...
Discriminative fine-grained mixing for adaptive compression of data streams
(Institute of Electrical and Electronics Engineers, 2014)
This paper introduces an adaptive compression algorithm for transfer of data streams across operators in stream processing systems. The algorithm is adaptive in the sense that it can adjust the amount of compression applied ...
Computing moments of first passage times to a subset of states in Markov chains
(SIAM, 2005)
This paper presents a relatively efficient and accurate method to compute the moments of first passage times to a subset of states in finite ergodic Markov chains. With the proposed method, the moment computation problem ...
