in order to study the effect of folic acid on seed reserves partitioning and early vigor of seedlings of kavir wheat cultivar, an experiment was conducted in a completely randomized design with 0, 12.5, 25, 50, 100 and 200 mm of folic acid. results of this study indicated that dry weight of seeds decreased in a same pattern in all treatments and about 6-8% of total seed was structural section. ...

Students need continuous programming practice in order to be able to correctly implement the concepts taught in programming classes. As a result, instructors will have high workload of marking and grading student’s program. Automatic correction and evaluation tools will be beneficial to reduce such workload. This article describes a web based multiplayer game named Algoshop that can be used to ...

EEective rate variation during active speech is a necessary component of sophisticated variable rate speech compression schemes. Here, we use open-loop estimates of spectral shape to roughly determine signal bandwidth and bit allocations for variable rate encoding of spectral parameters. We analyze the application of the relative entropy functional to sets of Line-Spectrum Pairs (LSPs) and tran...

We propose a variable-rate and variable-power MQAM modulation scheme for high-speed data transmission over fading channels. We first review results for the Shannon capacity of fading channels with channel side information, where capacity is achieved using adaptive transmission techniques. We then derive the spectral efficiency of our proposed modulation. We show that there is a constant power g...

In the past two decades, variation has received a lot of attention in mainstream generative phonology, and several different models have been developed to account for variable phonological phenomena. However, all existing generative models of phonological variation model the overall rate at which some process applies in a corpus, and therefore implicitly assume that all words are affected equal...
