The functional transformationmethod (FTM) is a well-establishedmathematical method for accurate simulations of multidimensional physical systems from various fields of science, including optics, heat andmass transfer, electrical engineering, and acoustics. This paper applies the FTM to real-time simulations of transversal vibrating strings. First, a physical model of a transversal vibrating los...

EDGE has enabled the GSM network to offer third generation services as part of the UMTS core network. This is due to the introduction of 8PSK modulation and the recent specification of interfaces from the GERAN to the UMTS core network. This paper studies further improvements to the spectral efficiency and capacity of EDGE through the use of more sophisticated adaptive modulation schemes based ...

We investigate a hybrid PDE/Monte Carlo technique for the variance reduced simulation of an agent-based multiscale model for tumor growth. The variance reduction is achieved by combining a simulation of the stochastic agent-based model on the microscopic scale with a deterministic solution of a simplified (coarse) partial differential equation (PDE) on the macroscopic scale as a control variabl...

Pruning techniques based on partial order reduction and symmetry elimination have recently found increasing attention for optimal planning. Although these techniques appear to be rather different, they base their pruning decisions on similar ideas from a high level perspective. In this paper, we propose safe integrations of partial order reduction and symmetry elimination for cost-optimal class...

Despite the fact that processes of deregulation and concomitant prudential re-regulation have recently been a dominant feature in financial markets of both developed and developing countries, relatively little empirical work has been done on their impact on bank competition and performance. This paper examines the impact of financial sector reforms on the cost structure characteristics and on t...

Referential integrity ensures the consistency of data between database relations. The SQL standard proposes different semantics to deal with partial information under referential integrity. Simple semantics neglects tuples with nulls, and enjoys built-in support by commercial database systems. Partial semantics does check tuples with nulls, but does not enjoy built-in support. We investigate th...

A previous research demonstrates the profitability of partial refund policies in a monopoly setting, there is a certain lack of ubiquity in practice about these refunds in competitive service markets. This raises the question of how a partial refund policy may work and whether it is even sustainable in a competitive environment. This study investigates how competition may influence the profitab...

On-chip capacity for storing temporal photon data in direct time-of-flight (dToF) lidar sensors is limited. This has prompted the development of various partial histogram approaches to reduce amount stored on-chip. The aim this paper inform sensor design by providing a taxonomy these approaches, models evaluating their impact on system laser power and identification additional trade-offs which ...
