Multistage heat pump drying of macadamia nut under modified atmosphere was studied to improve the drying process and quality of the nuts. Conditions of study included drying temperature of 40-60°C, using nitrogen and normal air as drying medium. Drying kinetics and quality of nuts (moisture content, aw, rancidity and colour) as well as energy consumption of all drying processes were examined. T...

We introduce the notion of LImited Memory Influence Diagram (LIMID) to describe multistage decision problems in which the traditional assumption of no forgetting is relaxed. This can be relevant in situations with multiple decision makers or when decisions must be prescribed under memory constraints, such as in partially observed Markov decision processes (POMDPs). We give an algorithm for impr...

A new multistage multipath amplifier design technique is introduced that combines the formerly distinct phases of stage design and compensation. The result is an inherently stable n-stage amplifier whose gain-bandwidth product is not compromised as the number of stages is increased. The technique relies upon (n 1) systematic pole-zero cancellations to achieve a near first-order open-loop system...

We study quantitative stability of linear multistage stochastic programs under perturbations of the underlying stochastic processes. It is shown that the optimal values behave Lipschitz continuous with respect to an Lp-distance. Therefor, we have to make a crucial regularity assumption on the conditional distributions, that allows to establish continuity of the recourse function with respect to...

We present a novel approach towards a multimodal analysis of natural speech and handwriting input for entering mathematical expressions into a computer. It utilizes an integrated, multilevel probabilistic architecture with a joint semantic and two distinct syntactic models describing speech and script properties, respectively. Compared to classical multistage solutions our single-stage strategy...

A new Constrained Storage VQ (CSVQ) structure based on linear transforms and translates of a common root codebook is proposed. The new VQ structure, named LT-CSVQ (Linear Translate CSVQ), acts as a building block for multistage VQ implementations (LT-CS-MSVQ), and significantly reduces storage requirements from that required in tree-multistage VQ implementations. LT-CS-MSVQ is most appropriate ...

Consider (typically large) multistage stochastic programs, which are defined on scenario trees as the basic data structure. It is well known that the computational complexity of the solution depends on the size of the tree, which itself increases typically exponentially fast with its height, i.e. the number of decision stages. For this reason approximations which replace the problem by a simple...

Models of linear and nonlinear optimal control applications are considered in which random discrete jumps in the system are state dependent in both rate and amplitude. These discrete jumps are treated as a Poisson processes in continuous time. This type of random noise allows for greater realism while modeling industrial and natural phenomena in which important changes occur with jumps. Modelin...

We introduce and study two new functional equations, which contain a lot of known functional equations as special cases, arising in dynamic programming of multistage decision processes. By applying a new fixed point theorem, we obtain the existence, uniqueness, iterative approximation, and error estimate of solutions for these functional equations. Under certain conditions, we also study proper...

This paper presents a hybrid shared memory architecture which combines the scalability of a multistage interconnection network with the contention reduction benefits of coherent caches. We achieve this by replacing the memory modules and final stages of a multistage interconnection network with clusters of coherent caches. The performance of Cache Coherent Hybrid Interconnected Memory Extension...
