I conducted a series of laboratory experiments to quantify the effects and elucidate the mechanisms by which Pseudacteon tricuspis Borgmeier phorid ßies affect the exploitative and interference components of interspeciÞc competition in host Solenopsis invicta Buren ants. In manipulative experiments, workers retrieved 50% less food in a foraging tray with phorids present, compared with an equidi...

The MSA Agent is the software developed to design rectangular and U slotted micro strip antenna. It is applied for the various applications such as satellite communications, UHF applications. Within the multimedia frequency range the developed software is tested and analyzed for various results. The software is developed using genetic algorithm. This provides extra flexibility and new capabilit...

Assorted analytical methods have been proposed for evaluating the performance of a slotted ring network. This paper proposes MGM (Matrix Geometric Method) to analyze the station buffer of a slotted ring for DT (Discrete-Time) queueing. The slotted ring is analyzed for infinite station buffer as a late arrival DT system. Utilizing the characteristics of 2-D Markov chain, various performance meas...

We study certain aspects of the Selberg sieve, in particular when sifting by rather thin sets primes. derive new results for lower bound sieve suited especially this setup and we apply them to give a sieve-propelled proof o

In this paper we will investigate the consequences of applying the sieve bootstrap under regularity conditions that are sufficiently general to encompass both fractionally integrated and non-invertible processes. The sieve bootstrap is obtained by approximating the data generating process by an autoregression whose order h increases with the sample size T . The sieve bootstrap may be particular...

We describe a very general abstract form of sieve based on a large-sieve inequality which generalizes both the classical sieve inequality of Montgomery (and its higher-dimensional variants), and our recent sieve for Frobenius over function fields. The general framework suggests new applications. We give some first results on the number of prime divisors of “most” elements of an elliptic divisib...

We consider the problem of stability of slotted ALOHA for a system consisting of N users communicating with a common receiver, which employs spatial diversity to receive multiple transmissions simultaneously. We introduce a general packet reception model to incorporate multiple packet receptions since the collision channel model is no longer valid in such a scenario. We characterize the stabili...

background: accurate impression making is an essential prerequisite for achieving a passive fi t between the implant and the superstructure. the aim of this in vitro study was to compare the three-dimensional accuracy of open-tray and three closed-tray impression techniques. materials and methods: three acrylic resin mandibular master models with four parallel implants were used: biohorizons (b...
