abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
several methods are used to decrease seed drying time and enhance the quality of dried seeds. influidization methods, good aeration occurs during the drying process. in this research, conditioned seedswith 20% d.b. moisture content were dried at 30°, 40°, 50° and 60°c using three bed conditions (fixed,minimum fluidized, fluidized). all experiments were done using a batch-type fluidized bed drye...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
Abstract—High moisture content in fruits generates post-harvest problems such as mechanical, biochemical, microbial and physical losses. Dehydration, which is based on the reduction of water activity of the fruit, is a common option for overcoming such losses. However, regular hot air drying could affect negatively the quality properties of the fruit due to the long residence time at high tempe...
increasing demands for cement, iron and steel industries for refractories with suitable workability in severeconditions (without any environmental risks), make the refractories’ researches to be an active area. refractories containing spinel has been developed with addition of chromia as a substitute in refractories using magnesite - chromite. in this research, different amounts of cr2o3 were a...
Impregnating wood, assisted with ultrasound technology, could improve the impregnation efficiency by improving the permeability of wood, thus affecting the subsequent drying process. Poplar lumber and phenolic resin were applied to investigate the influence of ultrasound-assisted impregnation on the wood drying process. The ultrasonic frequency and processing time were analyzed and correlated. ...
Three popular 100% cotton knitted fabrics, (plain single-jersey, 1x1 rib and interlock) were subjected to five cycles of four different washing and drying regimes. This was in order to investigate the effect of laundering with detergent as opposed to water, and tumble drying against line drying. The main aim of this work was to systematically investigate the effect of the principal washing and ...
The effect of different ultrasound pretreatment powers (0–500 W) before hot air drying on the moisture migration and quality Cantharellus cibarius (C. cibarius) was investigated in this study. results showed that accelerated rate. When power 400 W, time C. reduced by 18.90% compared with control group. low-field nuclear magnetic resonance (LF-NMR) imaging (MRI) increased water mobility cibarius...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
