The effect on the minimiim alveolar concentration of halothane (MAC) during extretne hypocapnia with oxygen, and with air, was determined in nine dogs. MAC was unaffected by hypocapnia with halothane-oxygen. Changing halothane-oxygen to halothane-air reduced the MAC significantly in only five of nine dogs. The average decrease in this group of nine dogs was H per cent, only slightly more than t...

This paper explores a MAC (Medium Access Control) layer throughput with DCF (Distributed Coordination Function) protocol in the IEEE 802.11a/g/n-based mobile LAN. It is evaluated in Rayleigh fading wireless channel, using theoretical analysis method. The DCF throughput performance is analyzed by using the number of stations with both variable payload size and mobile speed on the condition that ...

In [4], Bernstein presented a simple proof of security of Cipher Block Chaining (CBC) Message Authentication Code (MAC) against adversaries querying messages all of which are of the same length. In this paper we show that Bernstein’s proof can be used to prove security of CBC MAC against adversaries querying non-empty messages that are not prefixes of each other. This implies that “length-prepe...

We study the displacement map associated to small one-parameter polynomial unfoldings of polynomial Hamiltonian vector fields on the plane. Its leading term, the generating function M(t), has an analytic continuation in the complex plane and the real zeroes of M(t) correspond to the limit cycles bifurcating from the periodic orbits of the Hamiltonian flow. We give a geometric description of the...

This paper presents a technique for accessing channel based on sequencing technique for 802.11 wireless networks. The objective of this method is to reduce, as well as to avoid the number of collisions while accessing channel by many nodes at the same time. A concept of sequence number is introduced to avoid collisions. The transmission of a node takes place after checking the sequence number. ...

This paper examines the validity of purchasing power parity (PPP) using CPI and Big Mac prices. The benchmark model, i.e., the OLS method, which does not take nonstationarity into account, rejects the hypothesis of PPP regardless of prices used. We next use the panel cointegration method to consider the nonstationary nature of variables. Estimated results for CPI are mixed. The PPP is rejected ...
