In this paper, through the analysis of security threats to computer network information and protective factors conducted, a strategy for a common computer network information security and protection strategy has been proposed, and useful lessons for our computer network and information security and protection reference have been provided. A series of questions such as security and dependability regarding the computer network system arise, which has been taken into consideration in proposing the strategy. This paper puts forward proposals with respects to the importance of the computer network system, existing problems of the online security of the computer, and precautionary measures. The detailed discussion will help the mass users to become conscious regarding network security and take precautionary measures while using the network.","PeriodicalId":153592,"journal":{"name":"The Open Automation and Control Systems Journal","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133157222","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}

Related areas such as Wireless Sensor Networks and Internet of Things have been changing our daily lives. Context awareness is the key to the success of prospective applications, such as location based services and social information delivery. This paper focuses on the hot topic of how to store and manage this context information efficiently. To support social information routing, this paper brought forward an unbalanced slid- ing window based social structure mining algorithm. We also developed new concept of Context Objects Database, COD, which stored and managed various context information and objects such as time, location, interaction and so on. The pa- per mainly discusses the unbalanced sliding window model, fundamental architecture of COD. We also discuss the appli- cation of the COD such as mining social structure using sliding window model.

Gan","doi":"10.2174/1874444301507012051","DOIUrl":"https://doi.org/10.2174/1874444301507012051","url":null,"abstract":"In this paper, we prompt a new multi-dimensional logistics method based on the Internet of Things (IOT). In- ternet of Things is a good enabling technology for logistics and supply chains which implements seamless, real-time tracking and monitoring goods at the level of items. In this paper, we propose a solution, which adopts RFID/GPS/3G/GIS technologies to implement real-time surveillance of logistics in transit. Based on the proposed solution, we chose the tabacco logistics as an example and developed an actual monitoring system for Logistics & Distribution Center of China, which successfully implements real-time vehicle tracking and cigarette packages monitoring. The outcome indicates that this solution minimizes missing goods and effectively reduces wrong delivery. Internet of things (IOT), an application of the next gener- ation Internet, has received much attention and will be a worldwide competition emphasis because IOT can realize the interconnection between things and things, also between things and people. IOT will improve old industries and pro- mote new ones. The popularization and application of IOT will not only influence the progress of industrialization and informationization (1, 2), but also have far-reaching impact on social economy and human life. The construction of mod- ern logistics service system should be sped up to correspond with the development of informationization. Modern logis- tics should be the new force to promote the development of modern services as it has quicker reaction, integrated func- tion, serialization service, normalized work, systematic target, modern method, networked organization, marketing organi- zation and electronica information. It is of great theoretical value and realistic meaning to study the multi-dimensional synergy of logistic management in IOT environment. In recent years, competition among enterprises gradually evolved into the races between supply chains, the logistics operation presents an appearance of personalized service increasingly due to the changing market demand. Logistics is defined as part of the supply chain process by American Lo- gistics Management Association, which not only incorpo- rates logistics into a collaborative management category be- tween enterprises, but also requires enterprises consider their own logistics operation in a broader area. In addition, as management and information technology are crucial for the winning of enterprise group's competitive strength, the in- formatization construction of collaborative logistics man- agement is particularly important. As an emerging information technology, Internet of Things could achieve interactive information sharing and real-time monitoring of things, which is popular with enter- prises. If Internet of Things could be successfully applied to the construction of tobacco collaborate logistics platform, it will provide the most effective techniques and methods to solve the problems existing in the current tobacco lo","PeriodicalId":153592,"journal":{"name":"The Open Automation and Control Systems Journal","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122351170","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}

After obtaining the key image characteristics by using the SIFT algorithm, a gridding structure was built centered on the pixel point in each region, calculating the partial difference between the pixel points, and assigning weight to each pixel encoding with different contrasts. In this study, the model-based feature vector combining the Gabor algorithm was extracted to build the SIFT-GMLBP feature vector, which reduced feature dimensions by mapping of the original complement with each other. The test showed that the SIFT-GMLBP algorithm possesses a fairly good feature matching effect, with the correct matching rate over 95%, and reduced running time of 0.05S. The robustness of this method in dealing with the external environment is quite remarkable, as it is able to improve the speed and precision of the mobile robots’ image identification in the complex environment.","PeriodicalId":153592,"journal":{"name":"The Open Automation and Control Systems Journal","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127166799","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}

Firstly, a new formulation to estimate t is created by combining constant albedo and dark channel prior. Secondly, the watershed segmentation is introduced to divide the whole areas into some gray level consistent parts according to color distribution in the image so that user can better estimate the atmospheric light A, and also further avoid halo artifacts phenomenon. Finally, through this effective estimation to t and A, the scene visibility is largely increased and the haze-free scene contrasts can be better recovered. The experiment results demonstrate that our proposed method can provide comparable results to dark channel prior and obtain reliable estimation value t with the advantage of minimal halo artifacts and fewer unreal details.","PeriodicalId":153592,"journal":{"name":"The Open Automation and Control Systems Journal","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128578147","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}
