We prove the Weyl-von Neumann-Berg theorem for quaternionic right linear operators (not necessarily bounded) in a quaternionic Hilbert space: Let be a right linear normal (need…
A Simple Algorithm For Replacement Paths Problem
Anjeneya Swami Kare
Let G=(V,E)(|V|=n and |E|=m) be an undirected graph with positive edge weights. Let P_{G}(s, t) be a shortest s-t path in G. Let l be the number of edges in P_{G}(s, t). The \emph{…
Min-O-Mee: A Proximity Based Network Application Leveraging The AllJoyn Framework
Hatim Lokhandwala, Srikant Manas Kala, Bheemarjuna Reddy Tamma
Close proximity of mobile devices can be utilized to create ad hoc and dynamic networks. These mobile Proximity Based Networks (PBNs) are Opportunistic Networks that enable devices…
Evaluation of Channel Assignment Performance Prediction Techniques in Random Wireless Mesh Networks
M Pavan Kumar Reddy, Srikant Manas Kala, Bheemarjuna Reddy Tamma
Performance of wireless mesh networks (WMNs) in terms of network capacity, end-to-end latency, and network resilience depends upon the prevalent levels of interference. Thus, inter…
Displaced lepton flavour violating signatures of right-handed sneutrinos in supersymmetric models
Priyotosh Bandyopadhyay
We consider a extended supersymmetric model with a right-handed neutrino superfield which can generate light neutrino mass by Type I seesaw mechanism. The lighter superpart…

In this paper, we describe an enhanced Automatic Check- pointing and Partial Rollback algorithm(CaP R + ) to realize Software Transactional Memory(STM) that is based on con- tinuou…
Perturbation of closed range operators and Moore-Penrose inverse
S. H. Kulkarni, G. Ramesh
Let be complex Hilbert spaces and be a densely defined closed operator with domain and be the Moore-Penrose inver…
Multi-threaded Graph Coloring Algorithm for Shared Memory Architecture
Nandini Singhal, Sathya Peri, Subrahmanyam Kalyanasundaram
In this paper, we present multi-threaded algorithms for graph coloring suitable to the shared memory programming model. We modify an existing algorithm widely used in the literatur…

Parameterized Lower Bounds and Dichotomy Results for the NP-completeness of -free Edge Modification Problems
N. R. Aravind, R. B. Sandeep, Naveen Sivadasan
For a graph , the -free Edge Deletion problem asks whether there exist at most edges whose deletion from the input graph results in a graph without any induced copy o…
Multiversion Conflict Notion for Transactional Memory Systems
Priyanka Kumar, Sathya Peri
In recent years, Software Transactional Memory systems (STMs) have garnered significant interest as an elegant alternative for addressing concurrency issues in memory. STM systems…
On the expressive power of read-once determinants
N. R. Aravind, Pushkar S. Joglekar
