Urban traffic flow management requires continuous improvement in order to facilitate traffic in a smart way, solve traffic congestion problems and ensure good quality of service. The system representing urban traffic is a hybrid dynamic system, since it is made up of continuous processes interacting with discrete processes, where they can be represented by continuous dynamic type models (length of queues and time d evacuation of this length…) and has discrete events (control of traffic lights and the quantification of vehicles in the lanes). The objective is to organize the flow of these objects so that they are better distributed in the structure, according to certain criteria and constraints to be defined. We are interested in the structure of Petri nets and the application of the hybrid Petri net formalism as a graphical tool used in the modeling, the study of the dynamics and the performance evaluation of the hybrid system allows us to analyze these properties. By acting on the structure of the study model and on its parameters in order to evaluate its behavior and build a structured and optimal control system. Emphasis on the modeling of the urban traffic flow by the hybrid Petri Nets tool. Exploiting the timing of the Petri networks in the construction of the basic model of an intersection, with the quantification of vehicles we can estimate the Queue lengths so as to intelligently manage evacuation speed in intersections with appropriate time varying in order to control the crossing lights of adjacent intersections, applying this model to three related intersections between them and so on in order to facilitate the flow of traffic between the upstream and downstream intersections, the modeling and analysis of the results are checked and validated by a software simulator 'Visual Objet Net ++' under Windows.
The objective of this research is to determine the role of cultivation, processing and usage of rapeseed in Ukraine. To reach the aim used biochemical, analytical and statistical methods. The study has shown that within recent year’s increased sown areas, crop capacity and gross rapeseed yield. Variety composition of rapeseed represented by over 300 varietal numbers and over 100 hybrids: just 3 with low erucic acid/high glucosinolate content, single with high erucic acid/low glucosinolate and the rest – «double-zero» (low erucic acid, low glucosinolate). According to biochemical analysis of rapeseed, by-products (press cake and meal) can be useful as fodder all species of animals and poultry. Biochemical evaluation of seed and their processing products from registered in Ukraine rapeseed varieties and hybrids indicates their high quality. Therefore, it is possible to increase the introduction of rapeseed press cake and meal from "00" varieties into diets of farm animals and poultry in 1.5-2 times compared with "0" varieties.
The chemical composition of the essential oil obtained by hydrodistillation of the dried aerial parts of Pelargonium graveolens L. collected from the region of Khenifra (central Middle Atlas of Morocco) was studied by gas chromatography coupled with mass spectrometry which has enabled us to identified 54 constituents representing (99.99%). The major components are Geraniol (31.01%), Citronellol (29.52%), Linalool (10.50%), Citronellyl formate (9.06%), Geranyl formate (5.75%), and iso- Menthone (2.86%) with a total percentage of (88.7%). The insecticidal property was achieved against Tychius aureolus and Hypera postica. This preliminary study showed that the essential oil of Pelargonium graveolens L. exhibits remarkable toxicity towards these insects. The results of the tests showed a very important activity during 24 hours of the treatments confirmed by the values of LD50 and LD90. This activity was probably due to the major constituents. The antimicrobial power was studied in vitro against agricultural bacteria extracted from Medicago sativa L. Respectively Agrobacterium tumefaciens, Corynebacterium insidiosum, Pseudomonas, savastanoi pv. phaseolicola and Pseudomonas viridiflava. The results of the tests made it possible to quantitatively evaluate the bacterial power by looking for minimum inhibitory concentrations of MIC and minimum bactericidal concentrations of MBC, which showed a remarkable activity and an inhibitory effect against the strains tested.
The adaptation test of hybrid melon variety candidates was conducted in order to choose melon candidates for release as varieties. The main objective of this research was to select and test several candidates for hybrid melon varieties in three locations on the island of Madura, Indonesia. This research was conducted in three districts on Madura Island, i.e., Bangkalan Regency (longitude: 112044 E; Latitude: 7007 S; altitude: 5 m), Sampang Regency (longitude: 113008 E; Latitude: 7007 S; altitude: 25 m), and Sumenep Regency. (longitude: 113045 E; Latitude: 7002 S; altitude: 50 m). The planting materials used were nine genotypes of melon plants consisting of six hybrid melon variety candidates, i.e., MH-17, MH-29, MH-33, MH-37, MH-40, MH-42, and three comparison varieties, i.e., Anvi variety. Oren variety and Madesta variety. This research used a randomized complete block design with genotype as a treatment. The results showed that Genotypes MH-17 and MH-33 are recommended to be released to farmers because they had the characters of short harvest age (<70 days), high fruit weight (> 2,000 g), and high sugar content (> 10 0Brix) and had the same or greater character than the three comparison varieties (Anvi, Oren and Madesta).
Calcium, magnesium, and sulfur are secondary macronutrients to support crop’s growth after nitrogen, phosphorus and potassium. The study aimed to find out the optimum dose of CaO-MgO-S fertilizer for shallot in alluvial soil. Split plot experimental design and three replications were used. The main plot was two varieties of shallot, ‘Bima Curut’ and ‘Bangkok’. The sub-plot was the rate of CaO-MgO-S fertilizer, which consists of nine combinations. The ranges of the rates were CaO: 0-225 kg ha-1, MgO: 0-100 kg ha-1, and S: 0-100 kg ha-1. The result showed that there were no significant differences between the treatments on shallot bulb yield. ‘Bima Curut’ and ‘Bangkok’ showed the same responses to the treatments. The application of CaO-MgO-S fertilizer did not increase the shallot growth, nutrient uptake and shallot bulb yield significantly. However, giving 75 kg of Ca ha-1, 50 kg of Mg ha-1, and 50 kg of S ha-1 increased the fresh bulb yield by 20% than control.
