The proposed reverse converter is based on Mixed Radix Conversion (MRC). In addition to parallelizing and optimizing the MRC algorithm, the resulting architecture is further simplified in order to obtain a reverse converter that utilizes only 2 levels of Carry Save Adders and three Carry Propagate Adders. The proposed converter is purely adder based and memoryless. Our proposal has a delay of (10n + 4)t<sub>fa</sub> + 2t<sub>mUx</sub> with an area cost of (12n + 2)FAs and (2n)H As, which when expressed in terms of HA is (22n + 4), where FA, HA, and t<sub>fa</sub> represent Full Adder, Half Adder, and delay of a Full Adder, respectively. The proposed scheme is compared with state of the art similar dynamic range converters. Theoretically speaking, our proposal achieves about 62.3% hardware reduction and about 2.13% speed improvement when compared with the reverse converter for {2<sup>n</sup> + 1,2<sup>n</sup> 1, 2<sup>2n+1</sup> - 3, 2<sup>2n</sup> - 2}. Also, in comparison with the converter for {2<sup>n</sup> - 1, 2<sup>n</sup> - 1, 2<sup>2n+1</sup> - l}, the results indicate that, our proposal is about 17.05% faster, but requires about 7.83% more hardware resources. Further, the area time square (Δ<sub>T</sub><sup>2</sup>) metric indicates that our proposed converter is 62.3% and 24.77% better than the state of the art reverse converters for {2<sup>n</sup> + 1,2<sup>n</sup> - 1, 2<sup>2n+1</sup> - 3, 2<sup>2n</sup> - 2} and {2<sup>n</sup> - 1, 2<sup>n</sup> + 1, 2<sup>2n</sup>, 2<sup>2n+1</sup> - l} respectively.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73395286","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, it is difficult to handle heavy tasks with the MCU. To solve this problem, we developed a new sensor node that uses an ultra-low power field-programmable gate array (FPGA) in addition to an MCU. By assigning heavy tasks, such as sensor and data processing, to the FPGA, we can avoid overloading the MCU. Both the configuration data for the FPGA and the programs running on the MCU can be injected from outside the sensor node using wireless communication. Thus, the functionality of the sensor node can be easily changed depending on the situation and/or the applications. In this paper, we describe the sensor node architecture and its prototype, and then we show the experimental results.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77422440","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 study developed a way to design steps and collect data elements of the coffee-making process for a cooking workflow system. Caregivers were able to instruct senior citizens suffering from dementia remotely using this cooking workflow system. A multiple cameras based visual surveillance system was designed to facilitate the observation of cooking objects and senior citizens with dementia's cooking conditions in the kitchen, audio and graphical assistance were used to deliver instructions to the senior citizens with dementia. The smart kitchen environment is concretized into a smart kitchen prototype, this prototype affirmed the feasibility of the smart kitchen environment, and also revealed the areas for further improvement.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77862775","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 the framework of nonlinear and dissipative systems (ie. the flow of energy, substances, or sensory information), they generate stable internal oscillations as a response to environmental input and, in turn, utilise such output as a means of coupling with the environment.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73392347","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 translate the binary constraints of BQP into the equivalent quadratic equality constraints and employ the Lagrange multipliers method to deal these equivalent constraints. We derive the relation among the Lagrange multiplier, transmitting signal and noise. Since both transmitting signal and noise are unknown, it is impossible to solve the Lagrange multipliers exactly. However, in this paper, an estimation method is proposed to obtain the approximations of the Lagrange multipliers with low computational complexity. Numerical experiments show that the performance of the proposed method is very near to that of the ML detection.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84785929","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}

The importance of supporting automatic problem generation is to reduce the teacher's efforts and to personalize e-learning tasks for students enforcing their understanding of a subject. Also, the automatic verification strategy provides immediate feedback. Our approach is based on a standardization of learning tasks by providing a formal definition of the structure of a learning activity. As e-Learning platforms are evolving towards service-orientation, we prototype our strategy by developing an e-Learning component that can be used as a stand-alone application, or its logic can be exposed as a set of services for external applications.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86540699","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}
