Consequently, it sparked a wave of research in Soft Real-Time (SRT) scheduling algorithms for multicore processors producing many different scheduling algorithms that are good at harnessing the added power of the multicore processors but lack the required determinism to be used in Hard Real-Time (HRT) systems.We present the Multicore Priority Ceiling Protocol scheduling algorithm for HRT systems along with its schedulability test for HRT systems running on a single instance of a modified RTOS.

Meanwhile in the new scheme, nodes along the route do not send ACKs in MAC layer for acknowledging successful transmission between two neighbors. Instead, the CR function allows the previous hop to understand the transmission results, together with the real time multi-channel conditions. This proposal significantly reduces the required bandwidth through ACK message suppression. Simulation results show that the feedback of multiple-channel conditions also benefits the channel selection mechanism before data transmission therefore improving the network throughput by around 5% compared to the traditional MAC ACK scheme in CRMBR.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121605361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research investigates a new manner to cut down side effects of classical risks analyses.

To do so, the research method is three-folded: (1) a literature review is made to select relevant risk analyses and graph methodologies employed during design to ground our proposal (2) the proposal is built (3) the feasibility of this concept is tested over a real product design. The main result of this paper is to unveil a new manner to consider risks for improving their control during design stages.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114537484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A real-time soil moisture sensing system deployed at the root zone of a crop area for precise irrigation and an oil pipeline leak detection (PLD) system are particular examples of interest discussed in this work. Communication solutions for these scenarios have been recently investigated in the Wireless Underground Sensor Networks (WUSN) literature and magnetic induction (MI) technology is usually regarded as the best candidate for low-power and mid-range (i.e., 15..30m) wireless underground communication. Nonetheless, underground MI systems are still significantly impacted by changes at the electrical properties of the medium surrounding the MI nodes, such as due to the soil moisture variability. The design of a MI system for the worst-case scenario (e.g., high soil moisture) is a strategic approach but it may significantly reduce the application bandwidth. Therefore, the dynamic frequency adaptation has the potential of balancing robustness and higher bandwidth for MI-WUSNs. In this work, a novel design procedure is proposed for the optimization problem of selecting the proper operational frequency for MI-WUSN nodes according to the medium conditions.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126249895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a new technique to encrypt an image for secure image transmission and parallel decryption using cloud resources. The encoding of the image is done using the FFT conjugate complex property and private random phase key value shared between sender and receiver. First, using FFT complex conjugate property, we construct a two dimensional matrix consisting of real and imaginary portion of the image. Second, we encrypt the complex conjugate matrix using private random phase key value shared between sender and receiver. Detailed simulations have been carried out to test the encryption algorithm. Furthermore, we use cloud resources for the development of an efficient parallel image encryption and decryption algorithm. Significant speedup was achieved using different image size and number of cloud servers.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133492795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, manual safety evidence collection is usually tedious and time-consuming, due to a large number of artifacts and implicit relations between them. The potential ambiguities in the textual description of safety objectives even increase the difficulties of collecting the necessary safety evidence. Consequently, suppliers, who have to ensure that the required objectives have been fulfilled, need to investigate safety evidence requirements very carefully and rigorously to avoid collecting any ineffective information, or missing any important information. This paper proposes a systematic, model-based approach to facilitate manual safety evidence collection with clear evidence requirements. To evaluate the effectiveness of our approach, an industrial case study on an avionics Real-Time Operating System (RTOS) is conducted. A large number of evidence items are collected from thousands of artifacts (involving more than 10,000 test cases and nearly thousand pages of requirement specification), for demonstrating the compliance of system development with the avionic safety standard RTCA DO-178C.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129545623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Offloading the VSLAM processing to systems running in a cloud deployment of Robot Operating System (ROS) is proposed as a method for managing increasing processing constraints. The traditional bottleneck with VSLAM performing feature identification and matching across a large database. In this paper, we present a system and algorithms to reduce computational time and storage requirements for feature identification and matching components of VSLAM by offloading the processing to a cloud comprised of a cluster of compute nodes.

One of the biggest challenges of implementing M-government is user acceptance. This research offers theoretical and empirical insights related to the acceptance of government services via the use of the mobile phone system from a customer perspective. This paper adopts the technology acceptance model (TAM) and other theories to examine the influence on the user for accepting M-government services. In this study, TAM model was extended by adding three factors: experience, trust and time. All of these had a significant effect of the acceptance of M-government services. These factors have been reported in previous studies, but no study has incorporated all three factors. It was found that the parameters of the regression model are significant. Therefore, the variables adopted in this study play an important role in the acceptance of M-government in Saudi Arabia.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123299720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
