This paper introduces a distributed call admission controller for ad hod networks. The call admission controller is based on service curve provisioning. Service curve reflects the status of network and depends on the number of active nodes, their activity index, and the back-off procedure used for contention resolution. The service curve along with the aggregated traffic function can be used to...

A new notion of empirical informational divergence (relative entropy) between two individual sequences is introduced. If the two sequences are independent realizations of two finiteorder, finite alphabet, stationary Markov processes, the empirical relative entropy converges to the relative entropy almost surely. This new empirical divergence is based on a version of the Lempel-Ziv data compress...

ÐAn FPD switch module M with w terminals on each side is said to be universal if every set of nets satisfying the dimension constraint (i.e., the number of nets on each side of M is at most w) is simultaneously routable through M [8]. Chang et al. have identified a class of universal switch blocks in [8]. In this paper, we consider the design and routing problems for another popular model of sw...

background. one of the treatment methods for facial fractures is close reduction technique, but treatment with intermaxillary fixation (imf) interferes with normal nutrition, and malnutrition can affect patient’s recovery. anthropometric measurements such as skinfold thickness and body mass index (bmi) are universal indexes for diagnosing malnutrition. so in this study we pointed out how treatm...

The thermodynamics of general relativistic systems with boundary, obeying a Hamiltonian constraint in the bulk, is argued to be determined solely by the boundary quantum dynamics, and hence by the area spectrum. Assuming, for large area of the boundary, (a) an area spectrum as determined by Non-perturbative Canonical Quantum General Relativity (NCQGR), (b) an energy spectrum that bears a power ...

Minhashing is a technique used to estimate the Jaccard Index between two sets by exploiting the probability of collision in a random permutation. In order to speed up the computation, a random permutation can be approximated by using an universal hash function such as the ha,b function proposed by Carter and Wegman. A better estimate of the Jaccard Index can be achieved by using many of these h...

we extend the notion of semigroup compactification to the class of transformation semigroups, and determine the compactifications which are universal with respect to some topological properties.

Hsen-Che Tseng, Ping-Cheng Li, and Hung-Jung Chen Physics Department, National Chung Hsing University, Taichung, Taiwan R.O.C. Abstract We investigated the critical dynamics on the daily Taiwan stock exchange index (TSE) from 1971 to 2005, and the 5-min intraday data from 1996 to 2005. A global persistence exponent θp was defined for non-equilibrium critical phenomena [1, 2], and describing dyn...

The ht-index is a recently proposed tool for capturing dynamic views of the evolution process of geographic features, but the htindex is not sensitive to small changes during this process. To address this problem, an improved ht-index, a cumulative rate of growth (CRG) index, was proposed. Compared to the ht-index, the CRG index is more sensitive to changes during the evolution process of geogr...

The main purpose of this paper is to establish a relation between universality of certain P-compactifications of a semitopological semigroup and their corresponding enveloping semigroups. In particular, we show that if we take P to be the property that the enveloping semigroup of a compactification of a semitopological semigroup s is left simple, a group, or the trivial singleton semigroup, t...
