Abstract Today, Road traffic video surveillance becomes the centre of several concerns. It presents an important way for analysis of road traffic in highways. Road traffic video surveillance can help to resolve many problems which can influence road safety. This paper presents a real-time management and control system which serve to analyze road traffic using a stationary camera. The proposed system can measure the quantity and characteristics of traffic in real time based on three modules, segmentation, classification and vehicle counting. Our contribution consists of developing a feature-based counting system for vehicle detection and recognition under the conditions which present a challenge in recent systems, such as occlusions, and illumination conditions. Our method can perform vehicle detection and classification by eliminating the influence of many factors on system efficiency. The obtained results show that the system proposed in this paper provides a counting rate higher than that of some existing methods.

There were infected neonatal piglets in the first days of their lives PED virus suspension derived from pigs previously PED patients. Diagnosis for PED in piglets donor virus PED was inserted complex method for clinical and epizootic performance and confirmed the identification PEDV by PCR-RT using the test system «EZ-RED/TGE/PDCoV MPX 1.0 Real time RT-PCR» company Tetracore (USA) Thermocyclers CFX 96 Real-Time System company BIO RAD (USA). Homogenate small intestine of pigs PEDV donor, prepared in a blender for PCR in a thick band of 18 animal carcasses, frozen at -18 °C without cryopreservation and kept 359 days. Before infecting pigs and strip defrost by RT-PCR identified the concentration of the virus genome equivalents (GE) without establishing viable virions quantitative pathogen. For Sample 20 selected analog neonatal piglets, divided them into 3 experimental groups (group 1 – 5 piglets, group 2 – 5 piglets and group 3 – 7 piglets) and one control (3 piglets). Research pigs infected per os virus-containing suspension with a concentration PEDV 1.03×106 GE/cm3. The dose for infection first group was 6 cm3 (6.18×106 GE/cm3), for the second – 5 cm3 (5,15 × 106 GE/cm3), for the third – 4 cm3 (4.12 GE×106/cm3) homogenate. The fourth group – control (not infected). All the pigs were in identical conditions that fully meet the physiological needs of the body. Of the 17 infected pigs only 2 was infected PEDV. PED was confirmed by laboratory methods. In bacteriological examination of internal organs of pigs that came out of a research experiment and control group were diagnosed colibacteriosis. In the control group was isolated from heart and intestinal non-pathogenic for white mice E. coli. From pigs 1 and 2 research groups has been allocated to white mice nonpathogenic E. coli, is set colibacteriosis; 2 experimental group found in one pig hemolytic E. coli; 3 experimental group from the internal organs of pigs in conjunction with non-pathogenic for mice intestinal former cane isolated Klesiella spp., is diagnosed with mixed infection (E. coli, Klesiella spp.). From the intestine of experimental and control pigs do not identified beneficial microflora – aerococcus, lactobacteria, bifidobacteria and cultured putrefactive anaerobic spore facultative and non spore microflora.

Recent years, Unmanned Aerial Vehicle (UAV) has gained great attention and importance both in civil and military applications all over the world. Ground Monitoring and Control System (GMCS) is an important part of the entire unmanned helicopter system. As UAV develops rapidly, the functions and tasks are becoming increasingly complex, and the ground control station needs to collect more data. In addition, establishing a real-time and reliable communication system has become an important part of the control system of UAVs. The μC/OS-II operating system has the characteristics of modular application which can be used for multiple task operations, and can satisfy the requirement of real time system very well. And the system was successfully applicable to practical UAV fighter and the setting up of The Ground Monitoring Station.
