This note comments on the state of macroeconomics, arguing that the ‘micro founded’ macro that developed after 1970s has been a wasteful detour. The paper will appear in a symposium in Homo Oeconomicus, vol. 27 (2), 2010, on the crisis and the response from the British Academy to the questions from the British Queen. JEL classification: E1, B41 By the beginning of the 2000s, a self-congratulato...

In this paper, we demonstrate a new class of protocol-compliant exploits that initiates at the MAC layer but targets ad hoc on-demand routing mechanisms. A misbehaved node implementing this type of attacks completely follows the specifications of IEEE802.11 standard and the existing on-demand routing protocols. However, it can cause routing shortcut attacks or detour attacks. We detail the expl...

We have developed a hardware detour path selection facility for the Hitachi SR2201 parallel computer, which uses a multi-dimensional crossbar as an inter-processor network to ensure operating efficiency and high reliability when a part of the network is faulty. When this hardware facility is used, packets are transmitted to their destination along alternative paths to avoid the fault. However, ...

For the first forbidden unique (1u) radiative electron-capture b decay of Ca, a contribution of the g/b detour transitions via virtual nuclear states to the bremsstrahlung spectrum has been considered in terms of the shell model. Calculations of the matrix elements for the virtual E1 g and allowed Gamow-Teller b transitions have been performed with the use of the Warburton, Becker, Millener, an...

Let G be a plane graph where each edge is a line segment. We consider the problem of computing the maximum detour of G, defined as the maximum over all pairs of distinct points p and q of G of the ratio between the distance between p and q in G and the distance |pq|. The fastest known algorithm for this problem has Θ(n2) running time where n is the number of vertices. We show how to obtain O(n3...

MANET routing protocol based on P2P has become a hot topic, but mainly researches on small or medium MANET did not take full advantage of P2P distributed share theory, there still exist detour and inefficiency problems. This paper presents large-scale MANET distributed share routing model based on P2P. It introduces layered mechanism based on network physical topology to enhance network scalabi...

In the conventional IP network, equipment has been managed by periodical SNMP polling and periodical ping by a network management system (NMS), and traps have been used when abnormalities occur. But it is difficult to operate a service related to network state changes by such a management method because IP network services are best-effort services, so they may be affected by other multiplexed t...
