Significance As low-intensity fighting continues, neither Armenia nor Azerbaijan is ready to make concessions to facilitate a settlement determining whether Karabakh gains independence or reverts to Azerbaijan. Russia is supplying weapons to both sides: a short-range missile system to Armenia last year and additional anti-tank missiles for Azerbaijan this June. Impacts Russia's arms sales will create suspicion of its motives in both Armenia and Azerbaijan. Armenian leaders realise they have no option but to maintain defence ties with Moscow. Azerbaijan is likely to diversify its sources of arms imports to escape excessive reliance on Russia.

Road Geometry

Although Polish road network standards, in particular higher classes of roads are improving dynamically the number of fatalities on the network is still higher that EU’s average. Ensuring road safety and high maintaining standards is a complex issue and one that poses a major challenge for all road authorities. Road accidents at high speed roads characterize specially serious material and social consequences, thus research into road safety is of a special interest and numerous analyses and debates are being conducted worldwide as well as in Poland. In this paper the authors provide the results and recommendations coming from the analysis of accidents which happened on high speed roads during the heavy rainfall. The analysis of incidents which happened on sections with changing vertical alignment shows that a properly designed road geometry does not eliminate road accidents or conflicts.

<span>The task of this work is to design the guidance system for the<br /><span>missile which would guide the missile accurately to hit the target as<br /><span>directed. Guidance is the main component of the missile system which<br /><span>helps in hitting the target accurately. The missile can be guided by<br /><span>the number of ways which includes by using laser, GPS infrared or<br /><span>radio waves on its way to the target. This paper proposes a model to<br /><span>guide the missile with the help of GPS and INS. This model requires a<br /><span>computer or controller which should be installed in the missile to<br /><span>control the missile flight according to the guidance provided by GPS<br /><span>and INS. The system works by knowing the missile current position<br /><span>and the position of the target. The position of the target is known by<br /><span>using Google maps which is feed in the missile controller before the<br /><span>missile is launched. Missile current position is known by using GPS<br /><span>while the missile current orientation and heading is known by using<br /><span>INS. Missile current position is compared with the target position to<br /><span>calculate the desired heading towards the target, then missile<br /><span>controller auto pilots the missile according to the desired heading<br /><span>towards target to hit the target.</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span><br /><br class="Apple-interchange-newline" /></span>

Abstract In this paper, analysis and design of colpitts oscillator with ability to transmit data at low output power with application in short-range wireless sensor networks such as MICS is described. Reducing the area required to implement the transmitter, on-chip implementation and appropriate energy efficiency are the advantages of this structure that makes it suitable for the design of short-range transmitter in biomedical applications. The proposed OOK transmitter works at 405 MHz with 10 Mbps data rate. Output power and total power consumption are 25 µW and 726 µW, respectively. Energy efficiency is 72.6 pJ/bit. The transmitter has been designed and simulated in 0.18 µm CMOS technology.

Missile System

Over the years, India has been able to acquire a credible minimum nuclear deterrence. In this, the Agni missile system is integral to India‟s counter second-strike capability especially against China. The Agni category missiles are solid propelled ballistic missiles, ranging from short range missiles to intermediate range missiles (700-5000kms) with road and rail mobility providing greater chances of survivability during an enemy attack. This strengthens its scope of launching a counter/second strike. This makes India one of the few countries in the world with the ability to potentially decapitate its enemy by preserving its arsenal in the first attack from the enemy. This article provides a deep analysis of India‟s Agni missile systems.
