Fighting in the Donbas, which has been going on for more than five years, shows that a skillful counter-battery fight is an important factor in achieving success in wars of this kind. Especially in conditions where for the known reasons the use of combat aviation is minimized. With the development of technical warfare, the task of servicing the counter-battery fight began to rely on radar stations (radar) to reconnaissance the positions of artillery, which in modern terms are called counter-battery radar. The principle of counter-battery radar is based on the detection of a target (artillery shell, mortar mine or rocket) in flight at an earlier stage and making several measurements of the coordinates of the current position of the ammunition. According to these data, the trajectory of the projectile's flight is calculated and, on the basis of its prolongation and extrapolation of measurements, the probable coordinates of the artillery, as well as the places of ammunition falling, are determined. In addition, the technical capabilities of radars of this class allow you to recognize the types and caliber of artillery systems, as well as to adjust the fire of your artillery. The main advantages of these radars are:  mobility (transportability);  inspection of large tracts of terrain over long distances;  the ability to obtain target's data in near real-time;  independence from time of day and weather conditions;  relatively high fighting efficiency. The purpose of the article is to determine the leading role and place of the counter-battery radar among other artillery instrumental reconnaissance tools, to compare the combat capabilities of modern counter-battery radars, armed with Ukrainian troops and some leading countries (USA, China, Russia), and are being developed and tested in Ukraine. The method of achieving this goal is a comparative analysis of the features of construction and combat capabilities of modern models of counter-battery radar in Ukraine and in other countries. As a result of the conducted analysis, the directions of further improvement of the radar armament, increasing the capabilities of existing and promising counter-battery radar samples were determined.

Call Admission

Call admission control (CAC) is one of the radio resource management techniques that regulates and provide resources for new or ongoing calls in the network. The existing CAC schemes wastes bandwidth due to its failure to check before degrading admitted real-time calls and it also increases the call dropping probability (CBP) and calling blocking probability (CBP) of real-time calls due to the delay incurred when bandwidth is degraded from them. This paper proposed an enhanced adaptive call admission control (EA-CAC) scheme with bandwidth reservation. The scheme employs a prior-check mechanism that ensured bandwidth to be degraded will be enough to admit the new call request. It further incorporates an adaptive degradation mechanism that degrades non-real time calls before degrading the RT calls. The performance of the EA-CAC scheme was evaluated against two existing schemes using Vienna LTE system level simulator. The EA-CAC scheme exhibits better performance compared to the two schemes in terms of throughput, CBP, and CDP of RT calls without sacrificing the performance of NRT calls.

ObjectiveThe performance of comparative analysis of sensitivity and resultsof detection of avian influenza virus by real time polymerase chainreaction (PCR-RT) and loop-mediated isothermal amplification of thenucleic acids (LAMP) was the main goal of the study.IntroductionAs part of this surveillance study for Avian Influenza both activeand passive surveillance samples were tested using PCR and alsoutilized to validate the LAMP method. Active surveillance samplesinclude pathological material and tracheal and cloacal swabs fromill poultry, which were subsequently assessed for avian influenzaduring diagnosis, and birds collected by hunters. Passive surveillanceincluded environmental samples such as sand and bird faeces.Active surveillance samples were taken mostly from poultry farmsacross Ukraine, where infected birds are required to be diagnosedby State Scientific Research Institute of Laboratory Diagnosticsand Veterinary Sanitary Expertise (SSRILDVSE) by Ukraine Law.Passive surveillance samples were taken primarily during the annualbird migration season. Development of simple, sensitive, and cheapmethods for diagnostics of avian influenza is a very important taskfor practical veterinary medicine. LAMP is one of such methods.The technique is based on isothermal amplification of nucleic acids.It does not require special conditions and equipment (PCR cyclers),therefore it is cheaper in comparison with PCR. Accurate diagnosisis necessary for determining the risk associated with avian influenzain Ukraine and along the Dnipro River during the migratory season.MethodsFor the research, we used PCR-RT commercial kit Bird-Flu-PCR(Ukrzoovetprompostach, Ukraine), LAMP (the protocol has beenoptimized and patented by SSRILDVSE), QIAamp®Viral RNA MiniKit. For the study, we used pathological and biological materials frombirds, which were sent to the SSRILDVSE from all regions of Ukraineaccording to the 2013–2014 State monitoring plan.Set up of the real time PCR reactions and parameters ofamplifications are indicated in the instruction to the kit.The following protocol was used to set up the RT- LAMP: 2.5μL10 X Thermopol buffer, 1 mmol/L betaine, 5 mmol/L MgSO4,1.4 mmol/L - BNTP, 12.5μmol/L SYBR GREEN, 0.5 mmol/LMnCL2, up to 25μL Nuclease-free water, 8 U Bsm DNA polymerase,0.1μM/1 of F3, 0.1μM/1 of B3, 0.8μM/1 of FIP, 0.8μM/1 of BIP,0.4μM/1 of LF, 0.4 of LB, 2μL cDNA.During our work, we used the following optimal temperature andtime for the amplification – 59°C and 60 minutes.The sensitivity of diagnostic kit Bird-Flu-PCR and RT- LAMP wasdetermined by testing cDNA of the reference strain of AIV H5N1,which was provided to us by NSC Institute for Experimental andClinical Veterinary Medicine (Kharkiv, Ukraine). For the standard,we employed concentration in the range of 10.0-0.01 ng/sample.ResultsTable 1.This table shows the reproducibility results obtained by bothmethods. However, taken into account absence of highly pathogenicavian influenza virus circulating in Ukraine during the studied period,it was not possible to confirm these results with protocols of positivesamples.Table 2.It has been established that the sensitivity of PCR-RT kit Bird-Flu-PCR is 0.01 ng/sample for gene M and 0.1 ng/sample for subtypeH5N1.Fig. 1. Visual detection of LAMP products with differentconcentrations of cDNA of avian influenza virus (ng per sample):1 – 10; 2 – 5; 3 – 1.0; 4 – 0.1; 5–7 – 0.01; 8–9 – 0.1; 10 – negative.We have examined the LAMP results using electrophoresis forthe confirmation of visual detection and correct interpretation of theresults (Fig. 2).Fig.2. Electrophoresis results for LAMP products. M –molecular weight marker; 1 – 10.0; 2 – 5.0; 3 – 1.0; 4 – 0.1; 5–7– 0.01; 8 - negative control.It has been established that the sensitivity of LAMP is0.1 ng/sample. Slightly lower sensitivity of LAMP in comparisonto PCR-RT can be explained by visual detection of the products ofthe LAMP reaction.Conclusions1. Sensitivity of both methods is high.2. LAMP is a perspective screening method for the diagnosis ofviral infectious diseases supported by confirmation of positive resultsby PCR-RT.
