Rapid and Accurate INS Transfer Alignment for Air Launched Tactical Missile Using Kalman Filter

An Inertial Navigation System (INS) independently measures the Position, Velocity, and Attitude (PVA) of thevehicle to navigate it towards the target. Since INS is a dead-reckoning system, it requires accurate initialization toprovide the navigation (PVA) solution. In the case of an air-launched tactical missile, the aircraft navigation system(Master INS) information is used to initialize accurately the missile INS (Slave INS). Rapid transfer alignment isneeded in today’s combat operation to converge slave INS initialization in the shortest possible time using aircraftnavigation information. The transfer alignment consists of first initializing the missile INS and establishing anavigation solution (PVA) using the missile IMU rates and accelerations, then a Kalman filter is used to, estimatethe errors between the Slave INS and Master INS. The proposed method’s simulation results show that a tacticalmissile INS can be aligned to an acceptable accuracy in a very short time based on the aircraft’s attitude information and with natural maneuvers experienced during aircraft take-off

Decriminalization of Homosexuality

s. 377 - Unnatural Offences “Whoever voluntarily has carnal intercourse against the order of nature with any man, woman or animal, shall be punished with imprisonment for life, or with imprisonment of either description for a term which may extend to ten years, and shall also be liable to fine.”                Section 377 of the Indian Penal Code criminalizes several sexual activities such as homosexual acts. It was introduced more than a century ago during the British rule in India. In spite of being decriminalized by High Court once, the Supreme Court of India overturned the decision stating that it can be only be decriminalized by the legislature.                This is a paper that analyses the arguments in favor of as well as the arguments against the decriminalization of Homosexuality in India. The paper will also scrutinize some facts about Homosexuality and will finally arrive at the conclusion that it is fair to decriminalize Homosexuality

Laboratory investigations and performance evaluation of stone matrix asphalt as a wearing course using three different fibers

Bituminous mixtures are used as wearing and base course layers in a pavement structure and the performance of these mixes can be defined by its resistance against deformation, fatigue cracking, damage due to moisture and overall stiffness of the mixture. Rutting is one of the most important factors that lead to permanent failure of flexible pavements. The stone matrix asphalt (SMA) mixture is known to be highly rut resistant than other conventional wearing courses such as bituminous concrete. This paper describes the experimental examination conducted on stone matrix asphalt (SMA) mixes prepared using VG 30 grade of bitumen and different types of fibers such as cellulose fiber, coconut fiber, glass fiber and jute fiber as their additives. Results were then collated with SMA mixes prepared with different types of fibers. Investigation work comprises SMA mix design, static indirect tensile strength (ITS) and drain down test. From the test results, it was perceived that SMA with cellulose fiber has higher Marshall Stability and slightly lower drain down percentage as compared to all other fibers used. But indirect tensile strength for SMA mix prepared with jute fiber was higher than all other mixes.</p

Automatic Clause Boundary Annotation in the Hindi Treebank

In this paper, we propose a method for au-tomatic clause boundary annotation in the Hindi Dependency Treebank. We show that the clausal information implicitly encoded in a dependency structure can be made explicit with no or less human interven-tion. We exercised the proposed approach on 16,000 sentences of Hindi Dependency Treebank. Our approach gives an accuracy of 94.44 % for clause boundary identifica-tion evaluated over 238 clauses. The resul-tant corpus has varied usages and can be utilized for developing a statistical clause boundary identifier.
