in order to study the effect of temperature and photoperiod (pp) on development rate of different vegetative and reproductive stages of canola, an experiment was conducted at agricultural research station of gonbad during 2005-2007. the experiment was a randomized complete block design arranged in a split-plot in two conditions, for example supplemental irrigation and rainfed. there were differ...

The meteo-climatic datasets are at the basis of a great deal of studies on environmental state and its consequent management. In this frame, the completeness of meteo-climatic datasets is required for accurate and reliable analysis. Unfortunately, completeness is a rare in practice and, consequently, a preliminary treatment for filling in all gaps is needed. In this work, two intuitive and easy...

worth, perhaps we may say, in all. It is one of the most interesting features of the social framework of Britain, that while it recognises the distinctions of feudal rank, and records the exit of each worthy head of a time-honoured house, as in some sort the property of the nation, not the less through the various gradations of the scale does it appreciate the successful citizen, the independen...

Special attention has been focused on creating an ergonomic operator station that is not intimidating. This guarantees fast and efficient work, without fatigue, for many hours. The operator sits in front of the welder and manually loads parts to be welded into the enclosure. The operator has a clear view of the processing area through a large laser-safe window of protective glass. The final pos...

Vehicle crush measurements have typically been done using either offset methods or punctual survey methods such as with a total station or using photogrammetry. While offset grid methods are functional in determining 2-D displacement along the x and y-axis, vertical movement along the z-axis is much harder to achieve. Using a total station to complete crush measurements around a vehicle can yie...

We consider the time–continuous doubly–dispersive channel with additive Gaussian noise and establish a capacity formula for the case where the channel correlation operator is represented by a symbol which is periodic in time and fulfills some further integrability and smoothness conditions. The key to this is result is a new Szegö formula for certain pseudo–differential operators. The formula j...

We present a first study of the antiferromagnetic state in the 2D U–t–t′ model at finite temperatures by the composite operator method, providing simultaneously a fully self–consistent treatment of the paramagnetic and the AF phase. Near half filling the critical value of the Coulomb repulsion as a function of t′ and the temperature dependence of the magnetization and internal energy have been ...

In the down link scenario of code division multiple access (CDMA) systems, multi user detectors (MUDs) such as linear de-correlating detector (LDDs) provide satisfactory symbol error rates (SERs) at the expense of much increased complexity, they require all active users’ spreading sequences, which is impractical from privacy point of view. To overcome this impracticality, a simple matched filte...
