A trajectory correction flight control system is small and durable, and consists of a lateralpulsejet ring mounted on the rocket body. The pulsejet ring consists of a finite number of individualpulsejets. Each pulsejet on the ring imparts a single, short-... see more

Carbon dioxide is a gas denser than air, and its point-source ground emission from natural systems or from areas impacted by CO2 injection underground may result in hazardous accumulation, especially in topographically-depressed sites. The use of atmosphe... see more

The launch and impact points of a flight trajectory are estimated using U-D Kalman filterand Rauch-Tung-Striebel (R-T-S) smoother. Algorithms are implemented in PC MATLAB andvalidated using simulated data. The filter performance is evaluated in terms of s... see more

Intercepting reentry vehicles is difficult because these move nearly at hypersonic speedsthat traditional interceptors cannot match. Counterparallel guidance law was developed fordefending a high speed target that guides the interceptor to intercept the t... see more

Ample empirical studies in the e-commerce literature have documented that the price dispersion in online markets is 1) as large as that in offline markets, 2) persistent across time, and 3) only partially explained by observed eretailers’ attributes. Buyi... see more

The sustainability of irrigated agriculture depends on the quality of irrigation water used. The electrolyte concentration (EC) of irrigation water may lead to the accumulation of salts in the root zone layers and affect the physiological functions of the... see more

This study aims to determine whether the construction of the Center Point Of Indonesia (CPI) affects the socio-economic conditions of the people in the Makassar City sub-district. The independent variable in this study is the construction of the Center Po... see more

Launch vehicle explicit guidance mechanism depends on the estimation of the desired burnout conditions and driving the vehicle to achieve these conditions. The accuracy of the vehicle at the target point depends on how tightly these conditions are achieve... see more
