Force control enables hands-on teaching and physical collaboration, with the potential to improve ergonomics flexibility of automation. Established methods for design compliance, impedance control, collision response can achieve free-space stability acceptable peak contact force on lightweight, lower payload robots. Scaling collaboration higher payloads allow new applications, but introduces ch...

Internet accesses from mobile phones over cellular networks suffer from severe bandwidth limitations and high bit error rates in the wireless access links. Tailoring wireless link connections to best fit the characteristics of the link is thus very important. In this work, we propose a simple algorithm to find the optimal frame payload size in order to maximize the effective utilization of the ...

Digital watermarking is a robust method that allows a person to attach hidden data into the digital audio, video, or image signals and documents. In this paper, we propose a watermarking technique where initially, the watermark is embedded into the HL and LH frequency coefficients in multi-wavelet transform domain after searching the optimal locations in order to improve both quality of waterma...

High-Throughput Satellite (HTS) systems with digital payload technology have been identified as a key enabler to support 5G/6G high-data connectivity wider coverage area. The satellite community has extensively explored resource allocation methods achieve this target. Typically, these do not consider the intrinsic architecture of flexible payload, which consists multiple processors responsible ...


 A hybrid steganographic technique has been proposed to enlarge the size of secret message and hide several images in one cover image. Initially, were compressed using JPEG 2000 before embedding them Second least significant bit plane image was entirely replaced by while tri-ways-pixel-value-differencing (TPVD) used remaining seven-bit The quality stego enhanced residual coding (RIC). div...

Application-level traffic classification is an essential requirement for stable network operation and resource management. The payload signature-based classifier is considered a reliable method for Internet traffic classification. However, with this system, processing speeds are slower when high volumes of traffic are being classified in high-speed networks in real time. In this paper, we propo...

Thermal analysis was required in order to aid in the design and testing of a radiation tolerant computing (RTC) system using a radiation sensor. During development of the system, different test beds were employed in order to characterize the radiation sensor and its supporting electronic systems. The most common preliminary tests are high altitude balloon tests which allow the sensor to experie...

This paper proposes a histogram shifting method for image lossless data hiding in integer wavelet transform domain. This algorithm hides data into wavelet coefficients of high frequency subbands. It shifts a part of the histogram of high frequency wavelet subbands and thus embeds data by using the created histogram zero-point. This shifting process may be sequentially carried out if necessary. ...
