Singular Spectrum Analysis (SSA) is a relatively simple and powerful method in the area of time series analysis that is mainly based on matrix analysis. In this paper, we present a methodological comparison between the univariate and multivariate versions of SSA. Additionally, we explore the advantages of multivariate SSA in terms of theoretical results and with application to a real data set on currency exchange rates. 相似文献

The evolvable multiprocessor （EvoMP）, as a novel multiprocessor system-on-chip （MPSoC） machine with evolvable task decomposition and scheduling, claims a major feature of low-cost and efficient fault tolerance. Non-centralized control and adaptive distribution of the program among the available processors are two major capabilities of this platform, which remarkably help to achieve an efficient fault tolerance scheme. This letter presents the operational as well as architectural details of this fault tolerance scheme. In this method, when a processor becomes faulty, it will be eliminated of contribution in program execution in remaining run-time. This method also utilizes dynamic rescheduling capability of the system to achieve the maximum possible efficiency after processor reduction. The results confirm the efficiency and remarkable advantages of the proposed approach over common redundancy based techniques in similar systems. 相似文献

This paper started with the review of the history of technology acceptance model from TRA to UTAUT. The expected contribution is to bring to lime light the current development stage of the technology acceptance model. Based on this, the paper examined the impact of UTAUT model on ICT acceptance and usage in HEIs. The UTAUT model theory was verified using regressions analysis to understand the behavioral intention of the ADSU academic staffs’ acceptance and use of ICT in their workplace. The research objective is to measure the most influential factors for the acceptance and usage of ICT by ADSU academic staff and to identify the barriers. Two null hypotheses were stated: (1) the academic staff of ADSU rejects acceptance and usage of ICT in their workplace. (2) UTAUT does not predict the successful acceptance of ICT by the academic staff of the Adamawa State University. In summary, our findings shows that the four constructs of UTAUT have significant positive influence and impact on the behavioral intention to accept and use ICT by the ADSU academic staff. This shows that university academic staff will intend to use ICT that they believe will improve their job performance and are easy to use. The facilitating conditions such as appropriate hardware, software, training and support should be in place by the management. In the Adamawa State University, EE and SI are found to be the most influential predictors of academic staff acceptance of ICT and use among the four constructs of UTAUT. The greatest barriers are time and technical support for staff. Knowledge gained from the study is beneficial to both the university academic staff and the Nigerian ICT policy makers. 相似文献

The objective of this study was to determine the relationship aspect of the challenge, readiness, and the role of special education teacher (SET) in implementing common approaches in inclusive classrooms. Experiences as a moderator were used to see the effect of the co-teaching component. This study used a sampling method that involved 240 respondent’s representatives of the population of SET in Malaysia. The findings of this study showed that there was a high positive tendency in choosing the approach that is likely to progress than the existing ones. In this area, there were challenges and readiness of positive selection than teacher experience. Overall, this study could impact the implementation of co-teaching approach than the implementation of the existing programme. 相似文献

Detection of proteins and nucleic acids is dominantly performed using optical fluorescence based techniques, which are more costly and timely than electrical detection due to the need for expensive and bulky optical equipment and the process of fluorescent tagging. In this paper, we discuss our study of the electrical properties of nucleic acids and proteins at the nanoscale using a nanoelectronic probe we have developed, which we refer to as the Nanoneedle biosensor. The nanoneedle consists of four thin film layers: a conductive layer at the bottom acting as an electrode, an oxide layer on top, and another conductive layer on top of that, with a protective oxide above. The presence of proteins and nucleic acids near the tip results in a decrease in impedance across the sensing electrodes. There are three basic mechanisms behind the electrical response of DNA and protein molecules in solution under an applied alternating electrical field. The first change stems from modulation of the relative permittivity at the interface. The second mechanism is the formation and relaxation of the induced dipole moment. The third mechanism is the tunneling of electrons through the biomolecules. The results presented in this paper can be extended to develop low cost point-of-care diagnostic assays for the clinical setting. 相似文献
