“…This flexibility will not be available when using standard Operating System memory management and data acquisition mechanisms which are completely separated in an all-purpose Operating System. In the future we consider adapting parallel approaches [23,24] so as to make the suggested infrustructure suitable for parallel processing.…”

The next generation GPS will have many new features. Also the infrastructure will be noticeably enhanced. This has directed us to consider a new dynamic memory management strategic for the next generation GPS. The distinctiveness of the suggested infrastructure is shifting elements of the GPS applications to the Operating System with the objective of managing application data more efficiently. A key component of any GPS application is caching its data with the intention of preventing excessive memory accesses and allocations. The suggested infrastructure called "Cache Based Dynamic Memory Management" -CBDMM aims at moving the caching component from the GPS application to the Embedded Operating System of the GPS. The paper introduces CBDMM design, discusses its advantages and shows several encouraged benchmarking results.

“…These end-to-end numbers are more relevant than knowledge of actual network bandwidth, because decompression requires the use of receivers' CPU cycles. The sizes of the blocks have been preferred based on the common page size (Weisberg & Wiseman, 2009;Itshak & Wiseman, 2009) and the efficiency of compression techniques derived from Klein & Wiseman (2005). The ratios between the sending time and the reducing speed size have been set according to the statistics detailed in Figure 3.…”

Flight data recorders (FDRs, or black boxes) generate data that is collected on an embedded memory device. A well-known difficulty with these devices is that the embedded memory device runs out of space. To avoid getting into this problematic situation, the software of the FDR is designed to operate in a watchful mode, constantly working to minimize the use of memory space; otherwise a larger FDR would be needed. However, larger FDRs can be a problem because they have very rigorous requirements; thus, enlargement is costly. Outcomes of this research include the recommendation to send FDR data to a remote cloud storage system, so the data memory device will be unbounded.

“…Usually, when there is a non-zero value in a latter coefficient, a long sequence of zeros will be before this coefficient. A long sequence of zeros before a non-zero value is a very rare case [22,23], so unlike dictionary codes [24,25] the entropy encoder will yield for this data, a long sequence of bits. This will increase the size of the compressed image.…”

Abstract. There is threat for any data in the hands of a port; however, there is no cybersecurity standard for the maritime industry or for enforcement agencies; though the need of secure transmission is essential. Nevertheless, using encrypted messages have a significant disadvantage. Everyone who sees the message knows there is a secret message. This paper presents a way of Steganography, to be exact -transmitting encrypted messages in images compressed by JPEG format. The algorithm actually changes the pictures a bit, but this change is unnoticeable. The image seems to be an innocent picture, while actually it does contain a data.
