abstract     in order to study the relationships among seed yield and its components in nigella sativa, path coefficient and factor analysis was done using some agro- morphological traits of 21 different genotypes. genotypes were evaluated using a completely randomized design with four replications in ardestan university research farms. there was a high and positive correlation between seed yie...

This paper presents a clock selection algorithm for control-flow intensive behaviors that are characterized by the presence of conditionals and deeply-nested loops. Unlike previous works, which are primarily geared towards data-dominated behaviors, this algorithm examines the effects of branch probabilities and their interaction with allocation constraints. We demonstrate, using examples, how c...

The Intel Cluster OpenMP (CLOMP) compiler and associated runtime environment offer the potential to run OpenMP applications over a few nodes of a cluster. This paper reports on our efforts to use CLOMP with the Gaussian quantum chemistry code. Sample results on a four node quad core Intel cluster show reasonable speedups. In some cases it is found preferable to use multiple nodes compared to us...

This paper reports on an investigation into the basic properties and requirements of automatic speech recognition as an input device to a trial human computer interface. The experiments required subjects to carry out a simulated target acquisition and report filling task, with the available input devices being automatic speech recognition, trackball, function keys or a simultaneous combination ...

Project management methodologies have been the most utilized management tools in today’s industry and the Critical Path Method considers the logical dependencies between related activities that may have to share common resources. This method has then been expanded to allow for the identification of resource-constrained activities and the size of those resources. They are usually called activity...

In this paper, we propose a new fast and practical technique to eliminate known false paths during the static timing analysis (STA). False paths are verified fast using additional information stored in arrival times, which is a pass-through history of exceptional nodes. The information can be constructed with small memory overhead hecause individual false path list is not managed in each arriva...

In this paper, the concept of multimodal human-computer interaction is explored. It is proposed that multimodality can be de"ned from human or technology perspectives, which place emphasis on di!erent attributes of the system. Furthermore, in this paper it is argued that the most e!ective de"nition of multimodality concentrates on task and goal dependencies. Not only does this permit considerat...

Recently, an approach using the discrete event paradigm for the simulation of continuous systems has been developed. This approach is based on the use of piecewise-linear approximations for the representation of continuous, time-varying quantities. The focus of this paper is to show how this new technique can be implemented on a multiprocessor. Our hypothesis is that the Time Warp algorithm is ...

Observations from past earthquakes, such as the 1906 San Francisco earthquake, the 1994 Northridge earthquake, and the 1995 Hyogoken-Nanbu (Kobe) earthquake, have clearly demonstrated that compromising water supply systems after an earthquake not only impairs fire fighting capacity, but also disrupts residential, commercial, and industrial activities, and threatens the economic well-being, secu...
