This paper describes the DATA-CHASER Automated Planner/Scheduler (DCAPS) system which automated generation and repair of command sequences for the DATA-CHASER shuttle payload. DCAPS uses general Artificial Intelligence (AI) heuristic search techniques, including an iterative repair framework in which the system iteratively resolves conflicts with the state, resource, and temporal constraints of...

A model predictive control strategy is developed for an autonomous parafoil and payload system. Since the technique requires a linear dynamic model of the system, a reduced state linear model based on a nonlinear 6 degree-of-freedom parafoil and payload model is established and validated. In order to use the reduced state linear model for model predictive control the desired trajectory in the x...

Multimedia transmission over wireless local area networks (WLANs) is a challenging task due to the varying nature of the wireless channel as well as the inherent difference between multimedia traffic and data traffic. In the MAC layer, a single bit error in the packet can lead to the entire packet being discarded. This results in a higher packet error rate for higher payload sizes. Retransmissi...

To provide an added security level most of the existing reversible as well as irreversible image steganography schemes emphasize on encrypting the secret image (payload) before embedding it to the cover image. The complexity of encryption for a large payload where the embedding algorithm itself is complex may adversely affect the steganographic system. Schemes that can induce same level of dist...

The eventual goal of steganalytic forensic is to extract the hidden messages embedded in steganographic images. A promising technique that addresses this problem partially is steganographic payload location, an approach to reveal the message bits, but not their logical order. It works by finding modified pixels, or residuals, as an artifact of the embedding process. This technique is successful...

The H{\alpha} line is an important optical in solar observations containing the information from photosphere to chromosphere. To study mechanisms of eruptions and plasma dynamics lower atmosphere, Chinese Solar Explorer (CHASE) was launched into a Sun-synchronous orbit on October 14, 2021. scientific payload CHASE satellite Imaging Spectrograph (HIS). CHASE/HIS acquires, for first time, seeing-...

Recent advancement of optics fabrication, metrology and detectors are the basis for the development of a new compact instrument designed to provide daily revisit for the analysis of vegetation. The instrument has been optimized to improve multispectral imaging capabilities with respect to Spot-Vegetation, while minimizing mass and power to be accommodated on a small satellite. The new technolog...

Efficient delivery of stabilized nucleic acids (NAs) into cells and release of the NA payload are crucial points in the transfection process. Here we report on the fabrication of a nanoscopic cellular delivery carrier that is additionally combined with a label-free intracellular sensor device, based on biocompatible fluorescent nanodiamond particles. The sensing function is engineered into nano...

The Ministry of Research, Technology and Higher Education Indonesia routinely hosts a competition payload tracking system placed on rocket with Ground Control Station (GCS), known as Kompetisi Muatan Roket dan Indonesia. Fixed GCS antenna causes some problems, including poor communication between GCS, position detection the payload. This research was conducted to create capable moving towards p...
