in order to evaluate the delay cropping on yield and yield component of two canola cultivars and selecting the best genotype and row spacing, an experiment was conducted at three years (2007, 2008 and 2009) in gorgan research station. this experiment was arranged in spilt-factorial based on randomized complete block design with four sowing dates (28 oct., 12 and 28 nov. and 12 dec.) as main plo...

In this paper we consider the optimal trade-off between average transmission power and average queueing delay for a single user transmitting data over a wireless fading channel. In particular we study the behavior of this trade-off in the regime of asymptotically large power and small delay. Our focus is on channels which require infinite power to minimize the average delay. For such channels, ...

Understanding the service quality of Internet paths is of great importance for both the service provider and the user. Motivated by this and particularly the aim of extracting such information from a given dataset collected through end-to-end measurement, this paper presents a novel approach, called SCI (Service-quality Characterization of Internet-path). Specifically, SCI utilizes delay and lo...

| This paper discusses a statistical approach to static timing analysis. Delays of gates and wires are modeled by stochastic values instead of the triple best case, typical and worst case delay. This has the advantage of avoiding the overly pessimistic (optimistic) outcome of traditional worst (best) case calculations. The paper proposes a new scheme to perform the delay calculations with stoch...

In an expected reachability-time game (ERTG) two players, Min and Max, move a token along the transitions of a probabilistic timed automaton, so as to minimise and maximise, respectively, the expected time to reach a target. These games are concurrent since at each step of the game both players choose a timed move (a time delay and action under their control), and the transition of the game is ...

The design of logical topologies in wavelength-routing multihop optical networks is a well-studied problem. In this paper, we consider logical topology (LT) design over the popular ring and linear topologies. Our objective is the minimization of the electronic processing delay for the worst case traffic flow. For uniform traffic between nodes, this delay minimization corresponds to minimizing t...
