In this paper, we present experimental results supporting early work on the Seeding Genetic Algorithm. We evaluate the algorithm’s performance with various parameterisations, making comparisons to the Canonical Genetic Algorithm, and use these as guidelines as we establish reasonable parameters for the seeding algorithm. We discuss how experimental results complement and confirm aspects of the ...

We show genetic programming (GP) populations can evolve under the influence of a Pareto multi-objective fitness and program size selection scheme, from “perfect” programs which match the training material to general solutions. The technique is demonstrated with programmatic image compression, two machine learning benchmark problems (Pima Diabetes and Wisconsin Breast Cancer) and an insurance cu...

The experimental data are the result of a series of weather modification experiments conducted in south Florida from 1968 to 1972. These experiments were designed to test a hypothesis that massive injection of silver iodide into cumulus clouds can, under specified conditions, lead to cumulus growth, thereby increased precipitation. On each of 52 days that were deemed suitable for cloud seeding,...

Rapeseed as one the most crops is the basic needs of human feeding in order to produce oil. A field experiment was conducted to study the effects of different tillage system, seeding method and rates on yield and its components, as well as, seed oil percentage of rapeseed (Brassica napus L. cv. Hyola-401) during 2011-12 growing season at Rice Research Institute of Iran-Department of Ma...

Microporous hydroxy-sodalite zeolite membranes with different morphologies were synthesized via secondary growth technique with vacuum seeding on tubular α-Al2O3 supports at two different synthesis conditions (i.e. two different routes). Microstructures of the synthesized membranes were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM) and si...

This study presents a combined pneumatic seed-metering device (SMD) that could not only fill, carry, and meter seeds, but also switch quickly between seed-metering and seed-cleaning modes, and clean seeds thoroughly and rapidly. The seed-filling, seed-carrying, and seed-metering modes of the SMD were analyzed based on a theoretical kinematic model. Furthermore, a three-factor, three-level ortho...

 Homand Absard Rangeland Research Station is located 70 km northeast of tehran and 15 km southeast of Damavand with an altitude of 1972 m a.s.l., an average annual rainfall of 333 mm,  and a cold semi-steppe climate. In order to compare  the seed production of Vicia villosa under different cultivation seasons and methods, the seeds were initially collected from natural habitats similar to the m...

microporous hydroxy-sodalite zeolite membranes with different morphologies were synthesized via secondary growth technique with vacuum seeding on tubular α-al2o3 supports at two different synthesis conditions (i.e. two different routes). microstructures of the synthesized membranes were characterized by x-ray diffraction (xrd), scanning electron microscope (sem) and single gas permeation using ...

The objective of this study was to identify a combination of growth factors that could be used with hydrostatic pressure (HP) stimulation to enhance the functional development of cartilaginous grafts engineered using human infrapatellar fat pad derived stem cells (FPSCs) isolated from osteoarthritic patients. Agarose hydrogels were first seeded with FPSCs at different seeding densities and main...

OBJECTIVE To evaluate the feasibility of in vitro fabrication of tissue-engineered cartilage from human nasoseptal chondrocytes for autologous reconstruction. DESIGN Hyaline cartilage was reconstituted from chondrocyte-polyglycolic acid scaffolding constructs in a 3-dimensional mammalian cell culture cascade. This included monolayer cellular amplification, cell seeding in the spinner flask, a...
