There are large agricultural areas in the world where wheat yields are limited by low phosphorus (P) availability. Breeding for P uptake and P utilization efficiency may reduce this problem. This study was conducted to determine the contribution of P uptake and utilization efficiency to grain yield of selected spring wheat genotypes in different environments. Thirty-eight semidwarf spring bread...

This paper describes a GA for job shop scheduling problems. Using the Giffler and Thompson algorithm, we created two new operators, THX crossover and mutation, which better transmit temporal relationships in the schedule. The approach produced excellent results on standard benchmark job shop scheduling problems. We further tested many models and scales of parallel GAs in the context of job shop...

A system of midseason prediction of winter wheat grain yield based on sensed plant growth properties has been established. However, little research has been conducted to determine the relationship of grain yield, sensed plant data, and soil electrical conductivity (EC). This study was carried out to determine if soil EC could be useful in better predicting wheat grain yield. During 2001 and 200...

A green house field experiment of rice (Oryza sativa L) with arsenic amended irrigation water was conducted at Institute of Environmental Science of Rajshahi University to observe the trend of arsenic (As) accumulation into rice and soil. Sodium arsenate (Na2HAsO4) amended irrigation water (0.0, 0.1, 0.5, 1.0, 2.0 and 4.0 mg/l As) was used for cultivating a popular HYV-aman rice variety named B...

Our aim is to development of the inspection system of wooden chopsticks, and in this paper, we develop the prototype for high-class disposable wooden chopsticks by computer vision technology. We propose a method of inspecting the four items of fine grain sample, coarse grain sample, unpeeled sample, and defective sample. Moreover, we addressed not only the proposal of the algorithm but developm...

Scalable shared memory multiprocessors commonly employ replication and the associated coherency maintenance of memory blocks, but diier in the granularity from ne-grain (cache-coherent multiproces-sors) to coarse-grain (page-based distributed shared memory systems). Regardless of the size of coherency blocks, attaining good performance may depend on the number of copies staying small. Previous ...

Blowing dust from summer fallow is a major soil loss and air quality concern in winter wheat (Triricum aesrivum L.) production areas of the inland Pacific Northwest (PNW). The objective of our 3-yr onfarm study in a 286-mm precipitation zone in eastern Washington was to determine the effects of tillage mulch depth during fallow on surface soil roughness, residue retention, seed-zone water stora...

Recent evidence indicates that the exploitation of locality in dataaow programs could have a dramatic impact on performance. The current trend in the design of dataaow processors suggest a synthesis of traditional non-strict ne grain instruction execution and a strict coarse grain execution in order to exploit locality. While an increase in instruction granularity will favor the exploitation of...

In this paper we present the different modelling problems which a Digital Signal Processing (DSP) application designer has to tackle while refining an abstract specification relying on coarse grain data (e.g. matrices) toward a hardware implementation model relying on fine grain data (e.g. scalar). To address this problematic, we propose a modelling framework which can be used to refine an algo...

A key component to the success of multiscale modeling approaches is the ability to switch between molecular representations involving different levels of detail. In particular, the transition from a coarse to a fine representation is challenging because it requires the creation of information. To address this challenge, an algorithm is presented to fill in the detail when a coarse grain represe...
