This paper shows that a macroscopic fundamental diagram (MFD) relating flow and average density must exist on any street with blocks of diverse widths and lengths, but no turns, even if all or some of the intersections are controlled by arbitrarily timed traffic signals. The timing patterns are assumed to be fixed in time. Exact expressions in terms of a shortest path recipe are given, both, fo...

This paper proposes a fountain-code-based multi-path transport protocol, called heterogeneous multi-path transport protocol (HMTP), and evaluates its performance. HMTP improves the throughput performance and path utilization of multi-homing wireless erasure networks. It solves the receive buffer blocking problem and eliminates the need for retransmissions and in-order packet delivery, both of w...

a shortest path problem is a practical issue in networks for real-world situations. this paper addresses the fuzzy shortest path (fsp) problem to obtain the best fuzzy path among fuzzy paths sets. for this purpose, a new efficient algorithm is introduced based on a new definition of ideal fuzzy sets (ifss) in order to determine the fuzzy shortest path. moreover, this algorithm is developed for ...

In this paper we present a model of the dynamics of the industry for innovation and R&D management. It is a novel view of the evolution of industry, both in theoretical and computational terms. Industries are seen as organisations of firms and consumers, and the aggregated behaviour is the consequence of the decisions taken by the individual firms. A multiagent system is designed and programmed...

Use of FEC in off-line streaming, offering large buffers, gives spectacular results; but real-time streaming puts hard restrictions on the buffer size leaving FEC helpless for combating long link failures on a single path route. Another orthogonal method, the multi-path routing, can make FEC effective also for the real-time streaming, which has been already shown on examples with an alternate p...

Research on multi-path routing protocols to provide improved throughput and route resilience as compared with single-path routing has been explored in details in the context of wired networks. However, multi-path routing mechanism has not been explored thoroughly in the domain of ad hoc networks. In this paper, we analyze and compare reactive single-path and multi-path routing with load balance...

We experimentally show that two-photon path-entangled states can be coherently manipulated by multi-mode interference in multi-mode waveguides. By measuring the output two-photon spatial correlation function versus the phase of the input state, we show that multi-mode waveguides perform as nearly-ideal multi-port beam splitters at the quantum level, creating a large variety of entangled and sep...

Multi-path routing protocols are used for different types of wireless networks primarily to enhance reliability of packet delivery. The frequency of route discovery is also less for multi-path routing protocols as these are more fault-tolerant. However, the overhead of route discovery in terms of congestion and energy requirement is much higher for multi-path routing as compared to single-path ...

The formation of movement in a colony of animals in nature is as important as the movement itself. In transportation world or multi-agents system (swarm), like in military world, the formation of aircrafts or ships is also vital. This paper addresses the tracking situation of multi agents system that models swarming behavior moving along a desired path. This paper tries to model the movement of...
