Assessment of dynamic linear and non-linear models on rainfall variations predicting of Iran CIGR Journal
javari, majid.
The main research aims to detecting the linear and nonlinear variability modeling in analyzing the variability patterns of rainfall series. For rainfall linear and nonlinear variability modeling, the ARIMA models and ARCH family models has been used for predicting the monthly and annual rainfall series extracted from IRIMO during 1975-2014 within 140 stations in Iran. Several ARIMA and ARCH (six models) models have been used and their validity has been confirmed by evaluating different accuracy indicators, using the hybrid model for the variability modeling. The analysis of ARIMA and GARCH selective models indicates existence of random and non-random in the rainfall time series. The combination model of (1, 0, 0) and GARCH (1, 1) is applied for the...

Assessment of some physical properties of dried potatoes CIGR Journal
Hafezi, Negar; Sheikhdavoodi, Mohammad Javad; Sajadiye, Seyed Majid.
The effect of drying behaviour on the drying rate and quality characteristics of potato slices in a vacuum-infrared drying system was studied. In this research, the effect of the infrared radiation powers (100, 150, and 200 W) and vacuum levels (20, 80, 140 mmHg and atmosphere pressure) at different slice thickness (1, 2 and 3 mm) on drying rate and shrinkage percentage and rehydration capacity were investigated.  It was concluded that infrared radiation power amount has a significant effect on processing time and drying rate. With increasing radiation power, drying time is reduced and consequently drying rate is increased. The drying rate curve of potato slices at initial drying time is in the ascending phase because of surface moisture evaporation and...

Assessment of the impact of preventive maintenance strategy on reliability indicators of a rice combine harvester in the Gambia. CIGR Journal
minteh, mustapha.
Abstract: Maintenance cost of agricultural machines accounts for about 10 to 15% of total production cost and this tends to increase as the machine gets older. To stabilized this already high cost, agricultural machinery maintenance engineers chose Preventive Maintenance (PM) strategy. However, the latter may not produce the desired results especially when machines are used under different operating context. In this paper, an assessment of the effects of PM strategy on reliability indicators (failure rate, mean time between failures (MTBF), mean time to repair (MTTR) and mechanical availability) of a rice combine harvester Mitsubishi TVR96 working under the operating context of Pacharr rice fields in The Gambia, is discussed. These reliability indicators...

ASSESSMENT SLIPPERINESS OF FLOORING FOR FOOD INDUSTRY BUILDINGS CIGR Journal
Francesco Barreca; Mediterranean University of Reggio Calabria, Faculty of Agricultural Sciences.
One of the most common causes of accidents in food industry buildings is slipping caused, in particular, by the spilling of liquid substances on the floor, which reduces the coefficient of friction between floor and sole. The aim of this study was to assess the performance of the most common types of flooring used in the food industry, where, owing to the characteristics of the manufacturing stages, the probability of liquid spilling is higher. Five different types of flooring, usually utilized in the food industry, were tested: two unglazed gres tiles and three resin floors. The tiles were different in surface shape: one was flat (gres A), the other was a tile with embossed surface (gres B). The surface of the resin used was made up of a three-component...

Atmospheric Effects on Fate of Aerially Applied Agricultural Sprays CIGR Journal
B. K. Fritz; USDA-ARS, College Station,; W. C. Hoffmann.
The deposition and drift of aerially applied crop protection materials is influenced by a numberof factors including equipment setup and operational parameters, spray material, and meteorological conditions. This work focuses on evaluating the meteorological influences on the transport and ultimate fate of aerially applied sprays. There was no single meteorological factor that dominated the downwind transport of the spray treatments replicated in this study. Generally, lower relative humidity decreased downwind deposition and the amount of spray unaccounted for due to evaporative effects. Increasing wind speeds decreased both in-swath deposition and downwind deposition, and increased the amount of mass unaccounted for.Increases in stability were only...

Attribute Based Coding, Review and Gap Analysis of Cotton Harvesting Processes and Machines CIGR Journal
sharma, karun; kohli, s s; singh, manjeet; sharma, ankit; mishra, p k.
Mechanical cotton harvesters, i.e. strippers and pickers are commercially available, but these cannot be used for cotton harvesting from varieties presently grown in India due to design constraints and agronomic practices. Higher initial cost and field capacity make cotton harvesters unsuitable and unaffordable for small and medium farms. Hence, a comprehensive review of cotton harvesting mechanisms developed till date was carried out. Different attributes relating to problem have been expressed in matrix form to identify of crop and machine parameters which could be utilized by Researchers, Engineers and Manufacturers for development and refinement of mechanical cotton harvesters for small and medium farms. The matrix depicts on academic work of each...

Authentication of Virgin Olive Oil by Using Dielectric spectroscopy combined with Some Artificial Intelligence Methods CIGR Journal
Soltani, Mahmoud; Rashvand, Mahdi; Teimouri, Nima; Omid, Mahmoud.
Adulteration is a serious problem in the food industry. Olive oil is widely adulterated with other cheap edible oils such as sunflower and canola oils. Therefore, developing a low-cost, practical and rapid analytical method for detecting such adulteration in olive oil would be useful and needed.  In this research, we aimed to develop a dielectric measurement based system combined with complementary analytical intelligent techniques to recognize authentication of virgin olive oil from adulterated with vegetable oils (canola and sunflower). 192 sinusoidal signals in the range of 20 kHz and 20 MHz were feed into the cylindrical dielectric sensor filled with oil sample. Correlation based feature selection (CFS) was applied to select the most appropriate...

Autonomous Guidance of a Corn Harvester using Stereo Vision CIGR Journal
F. Rovira-Más; S. Han; J. Wei; J. F Reid.
The growing demand for applications in Precision Agriculture has been proportional to the emergent interest in automatic guidance of agricultural machines. The difficult, and at the same time strenuous, task of driving a harvester during the prolonged working days of the harvesting season justifies the special attention paid to this technology. The development of Global Navigation Satellite Systems has meant an important push for autonomous navigation, especially in the case of off-road vehicles. However, experience has shown that automatic guidance inside the tight arrangement of crop rows is difficult to achieve unless local positioning sensors take part in the localization unit of auto-steered machines. This research develops a perception engine based...
