Automated Fruit Grading System is challenging task in ICT in agriculture. This paper presents a new fruit grading system using artificial neural networks (ANN). The classification systems are based on features extracted from fruits obtained from image processing feature extraction methods. Two different types of classifiers as multi-layer perceptions (MLP) with back propagation and radial basis function (RBF) networks. The objective of this study are to define a optimistic set of external quality features of fruits from the primitive features like color, texture and shape of fruits and to examine the effectiveness of the model. In this experiment, the performance of the system achieved 87.5% and 91.1% respectively for MLP with back propagation and RBF.

The biological parameters and zooplankton diversity of a Tampara Lake shows healthy aquatic ecosystem. The plankton constitutes the basic food source of any aquatic ecosystem. Zooplankton diversity is one of the most important ecological parameters in water quality assessment. Zooplankton are strongly affected by environmental condition and quickly respond to any change in water quality. So these are good indicator of ecosystem and occupy an intermediate position between phytoplankton and fish. Hence qualitative and quantitative studies of zooplankton are of great importance. During the study zooplankton diversity in relation to biological parameters was discussed to the investigation find that 22 species of zooplankton belonging to four major groups, i.e. 10 species of Rotifera six species of cladocera and three species of copepoda and three species of protozoan.

Oral habits are very common and one of the most deleterious habits which pose a problem to pediatric dentists. Oral appliances, if inserted for several months, usually eliminate the habit, however, emotional problems, difficulty with speech and hearing, and self inflicted wounds can occur with such appliances. We present a case of 8 year old girl with thumb sucking habit, successfully managed by a non punitive bluegrass appliance.

In this paper the existence of odd and even ratio edge antimagic labeling for double triangular snakes (2?k-snake), 2m?1-snake, 2m?k-snake and kC4-snake are proved.

This paper proposes a the common sharing distributed arithmetic method with less number of flip flops to reduce the power consumption by the circuit. To achieve the lesser number of Flip flops usage the registers used in the circuit to create latency will be replaced by buffers. By using the buffers in the circuit itself can create some latency efficiently than using the more number of flip flops in the circuit.

The main chemical used for the gold mining is Mercury. It is widely considered to be among the highest priority environmental pollutants of great concern to the world. Concerns about mercury are based on its effect both on ecosystems and human health. Mercury levels in various foodstuffs were determined by instrumental neutron activation analysis (INAA). High level of Hg was found in all the foodstuffs collected from mining areas. Generally, Hg concentration in foodstuffs ranged from Capsicum sp <0.01 to 69 µg/kg > Xanthosoma sagittifolium <0.01 to 67µg/kg, Nbelmoschus esculentus <0.01 to 67 µg/kg > Colocasia esculentus <0.01 to 66 µg/kg > Manihot esculentus <0.01 to 65 µg/kg , Musa paradisiacal <0.01 to 65 µg/kg , leaves of Xanthosoma sagittifolium, <0.01 to 65 µg/kg > Solanum melongena <0.01 to 63 µg/kg, > Lycopersicum esculentus <0.01 to 54 µg/kg. Most of the values far exceed the WHO recommended values of Hg in foodstuffs, 20ngHg per gram fresh weight. This is not surprising because of the large amount of mercury the illegal miners add in order to be sure that they have all amalgamated available gold. Hg levels should be carefully monitored in the Wassa west district in Ghana.

In this research modeling of moisture content of three different varieties of bean (Talash, Sadri and MahaliKhomein) was studied during soaking by applying Khazaei mathematical model and artificial neural networks (ANNs). The procedures were carried out in three experimental temperatures (5, 25 and 45?C) in distilled water. Water abortion characteristics of samples were considered by measuring the increase in the mass of seeds with respect to time. Amulti layer perceptron (MPL) and radial basis function (RBF) approach were used with three layers of neurons, in designing ANNs. The soaking temperature and time were used as input parameters and the moisture content was used as output parameter of ANNs. To evaluate the prediction of mathematical and ANNs model, coefficient of determination (R2),root mean square error (RMSE) and distribution of residual errors plot were used. The results indicated that the MLP approach using back propagation training structure, Broyden- Fletcher- Goldfarb- Shanno(BFGS) algorithm and 2-6-1 topology of the network achieves the best results for moisture content estimating in three studied varieties of bean. Besides that, the instant moisture content curves based on temperature and time independent variables using MLP method expressed with increasing the time and temperature of seed immersion, water absorption is increasing.

Reticulocytosis is an important previously unappreciated surrogate marker of recent Plasmodium falciparum reticulocyte parasitation. Evidence from studies in murine and primate models show increased prevalence of Plasmodium falciparum parasitisation of reticulocytes. The increase in reticulocyte infection has been attributed to compensatory reticulocytosis and increased parasite densities. However, the prevalence of P. falciparum parasitisation of reticulocytes in human populations in holoendemic areas of malaria is unknown. Therefore, the current study examined the prevalence of P. falciparum parasitation of reticulocytes and its association with clinical, parasitological and haematological outcomes in children (n=164) and adults (n=41) with acute P. falciparum malaria and healthy malaria-negative controls (children, n=132 and adults, n=60) from a holoendemic area of malaria of western Kenya. Malaria diagnosis and species identification was performed using Giemsa-stained thick and thin blood smears while reticulocyte parasitation was determined using New Methylene Blue- Giemsa counter-stained thin blood films. Results of this study showed that children with malaria presented with increased numbers of infected reticulocytes compared to adults with malaria (p=0.006; Mann-Whitney U test). In addition, children with malaria presented with higher reticulocyte counts compared to those without malaria (p<0.0001; Mann-Whitney U test).

The paper considered the construction of a family of BIBDs using potential Lotto Designs (LDs) earlier derived from qualifying parent BIBDs. We utilized Li’s condition, to determine the qualification of a parent BIBD as LD constrained on and then considered the case since is the smallest number of tickets that can guarantee a win in a lottery. The BIBD was used as the parent BIBD for the procedure. This BIBD yielded three potential LDs each of which was completely generated using a Microsoft Office Access database computer program and their properties were studied. The three LDs, after their complete generation, yielded the and BIBDs. These BIBDs follow the generalization where are the parameters of the BIBD. A MATLAB program was used to generate a family of the BIBDs for with these new set of parameters. All the BIBDs in this family are unreduced designs.

Estimating the annual volume of the aquifer basin is of the main issues in designing the aquifer projects. Since the aquifer basin of central Iran covers half of country and a great number of the aquifer basins are situated in the arid and semi arid regions of the hydrometric stations, their watering figures are estimated by experimental models. The general structure of these models in some cases brings about considerable differences in the estimated and observed figures resulted from an incorrect selection of a model. This study has made use of 9 experimental formulas of Justin, Lisi, the world Meteorology Organization ratio, Agricultural Research Association of India, ICAR, Khosla, Turc, the Irrigation Department of India, and Inglis and De Souza for calculating the annual runoff in the water basin of Iran. Therefore for selecting the basins with the least annual natural and artificial Debi changes, the equal aquifer basins with an area less than 300 square kilometer which had no stank and vast agricultural lands which had little to middle degree of penetrability were firstly chosen. In selecting and determining the basin border two soft wares, Google earth, and ArcGIS were used, then the geological, climatological, and land applicability maps of the studied basin were prepared and their hydro climatologic statistics in the common 30-year-old time limit (1976- 2005) were extracted. At the end, the annual runoff altitude of the selected stations was determined using the aforementioned 9 ratios and these outcomes were compared with the observed data of the stations using four methods MAPE, RMSE, t distribution, and the unilateral analysis variance. The results show the superiority of Khosla to the other methods in the arid and semi arid regions. The estimated data in both arid and semi arid climates were studied separately, in both cases Khosla was selected as the most appropriate method.
