This paper studies external memory bidirectional search. That is, how bidirectional search algorithms can run using external memory such as hard drives or solid state drives. While external memory algorithms have been broadly studied in unidirectional search, they have not been studied in the context of bidirectional search. We show that the primary bottleneck in bidirectional search is the que...

This paper closes a definitional gap in the context of modeling cryptographic two-party channels. We note that, while most security models for channels consider exclusively unidirectional communication, real-world protocols like TLS and SSH are rather used for bidirectional interaction. The motivational question behind this paper is: Can analyses conducted with the unidirectional setting in min...

The development of electromobility involves the electric cars charging infrastructure. increase number chargers poses new demands for AC power grid, especially in regard to its capacity delivering high peak power. As an alternative public urban electrified transportation systems (trams, trolleybuses, and metro) can be used supplying chargers. article discusses four options integrating with a tr...

Capturing surface appearance is important for a large number of applications. Appearance of real world surfaces is dif cult to model as it varies with the direction of illumination as well as the direction from which it is viewed. Consequently, measurements of the BRDF (bidirectional reectance distribution function) have been important. In addition, many applications require measuring how the e...

We inve,tigate by ~tati,tical mechanical methods a uocha~tic analogue of the bidirectional a;sociative memone~ introduced by B. Kosko. We denve its ;torage capacity a~ a function of the total number of synapses and of the asymmetry of the network.

Cotton cloth is a commonly encountered material in everyday life, and a realistic model for its appearance is needed for rendering clothing and environments in many computer graphics applications. For realism it is important to produce the correct texture when the pattern of threads is resolved in the image, but cloth must also be rendered efficiently in more distant views when the thread patte...

Previous research has shown that Bidirectional Associative Memories (BAM), a special type of artificial neural network, can perform various types of associations that human beings are able to perform with little effort. However, considering a simple association problem, such as associating faces with names, iterative type BAM networks usually take hundreds and sometimes thousands of learning tr...

During mother-infant face-to-face interactions, bidirectional influence could be achieved through either the entraining of periodic cycles in the behavior of each partner or through the stochastic organization of behaviors. To determine whether and how bidirectional influence occurs, we used both timeand frequency-domain techniques to study the interactions of 54 mother-infant pairs, 18 each at...

Many scattering models have been presented in the graphics literature. Few of them, however, have been evaluated through comparisons with real measured data. As the demand for plausible and predictable scattering models increases, more attention is given to performing such comparisons. In this paper we examine the implementation of virtual goniphotometers used to obtain BRDF (bidirectional refl...

Existing bidirectional reflectance distribution function (BRDF) models are capable of capturing the distinctive highlights produced by the fibrous nature of wood. However, capturing parameter textures for even a single specimen remains a laborious process requiring specialized equipment. In this paper we take a procedural approach to generating parameters for the wood BSDF. We characterize the ...
