• Networks have been found through simulated annealing with mean internodal distances lower than any previously reported for a given number of nodes $N$ with a maximum of $p$ outgoing links per node. These networks form the closest known approximations to Moore networks. However, the improvements in mean internodal distance obtained are relatively small (a few percent) and this improvement decr...

The "concept of restricted intracellular water diffusion at permeable boundaries", which was recently used to model diffusion-weighted 1H NMR experiments on glioma cells, was applied to measurements on the rat brain in vivo. Combined with the "concept of extracellular tortuosity", various physiological states of the brain were simulated. Hereby, a variable intracellular volume fraction, intrace...

Clusterwise regression is applied to functional data, using PCR and PLS as regularization methods for the functional linear regression model. We compare these two approaches on simulated data as well as on stock-exchange data.

In this paper, we study the over-constrained airport gate assignment problem where the objectives are to minimize the number of ungated 4ights and total walking distances or connection times. We 7rst use a greedy algorithm to minimize ungated 4ights. Exchange moves are employed to facilitate the use of heuristics. Simulated annealing and a hybrid of simulated annealing and tabu search are used....

In multi-agent scenarios where the communication overload is important the number of questions exchanged may impact negatively on the efficiency of the MAS. We present in this report different critical question orderings in simulated dialogues about plans to identify the best ordering in terms of the number of questions exchanged. In the type of dialogue we are considering the question-answer e...

An optimization model for Timber Harvest Planning (THP) is used to form harvest areas with the objective of maximizing the tree harvest volume subject to harvest regulations. Most optimization models for THP currently in use are based on clear cutting and restricted to adjacency constraints to prevent the creation of large clear-cut openings in the forest. However, an optimization model based o...

one of the ways to be informed on the extent of activities in various industries is to measure the rate of nominal protection. this paper tries to calculate the nominal and effective protection in order to examine the exchange rate unification impacts on the protection of pulp and paper industries with the aim of performing the exchange rate unification policy. therefore, nominal protection rat...

the main purpose of this paper is theoretically to design the optimal intervention in the foreign exchange market in iran, which has not been investigated by previous studies. the economic fundamentals are strongly affected by the optimal foreign exchange intervention, the consistency of foreign exchange intervention with other policies and political authorities' beliefs about the interven...
