We describe a metalanguage MMML, which makes explicit the order of evaluation (in the spirit of monadic metalanguages) and the staging of computations (as in languages for multi-level binding-time analysis). The operational semantics of MMML is very intuitive and consists of two parts: local (semantic preserving) simplification rules, and steps of computation executed in a deterministic order (...

Median filter is widely used to remove impulse noise without blurring sharp edges. However, when noise level increased, or with thin edges, median filter may work poorly. This paper proposes a new filter, which will detect edges along four possible directions, and then replace noise corrupted pixel with estimated noise-free edge median value. Simulations show that the proposed multi-stage direc...

Testifying to more than ten years of academic and practical developments, this tutorial attempts to provide a succinct yet unified view of the robust multi-stage decision making framework. In particular, the reader should better understand: (1) the distinction between static versus fully or partially adjustable decisions; (2) the root of tractability issues; (3) the connection to robust dynamic...

Video monitoring systems are a necessity in the modern times. Although some people object the idea of ‘being watched’, surveillance systems actually improve the level of public security, allowing the system operators to detect threats and the security forces to react in time. Surveillance systems evolved in the recent years from simple CCTV systems into complex structures, containing numerous c...

In this letter, adaptive multi-stage parallel interference cancellation (PIC) receiver is considered for multi-rate DS-CDMA system. In each stage of the adaptive multi-stage PIC receiver, multiple access interference (MAI) estimates are obtained by the sub-bit estimates from the previous stage and the adaptive weights for the sub-bit estimates. The adaptive weights are obtained by minimizing th...

This chapter aims to unify concepts and to describe the multi-stage transport systems and their integratyion to supply chain management. Multi-stage distribution systems are common logistics management, and often they are assimilated to multi-stage transport strategies. However, transport is often considered as an external operation or a specific stage, even when it is a multi-stage system. Fir...

Stochastic optimization problems provide a means to model uncertainty in the input data where the uncertainty is modeled by a probability distribution over the possible realizations of the data. We consider the well-studied paradigm of stochastic recourse models, in which the realized input is revealed through a series of stages and one can take decisions in each stage in response to the new in...
