In understanding online search behavior, this fact may favor a certain group of search type and, therefore, may mislead managers in allocating their financial spending efficiently. We analyzed a large query log for the occurrence of user-specific interaction patterns within and across three different industries (clothing, healthcare, hotel) and were able to show that users’ online search behavior is indeed a multi-stage process, whereas e.g. a product search for sneakers typically begins with general, often referred to as generic, keywords which becomes narrowed as it proceeds by including more specific, e.g. brand-related (“sneakers adidas”), keywords. Our method to analyze the development of users’ search process within query logs helps managers to identify the role of specific activities within a respective industry and to allocate their financial spending in paid search advertising accordingly.","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130609748","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 is the case of the Mobile Telephony segment of the Information and Communication Technology (ICT) industry. In this competitive setting, potentially disruptive changes in both marketing and technological dimensions are the norm, as attested by the recent decrease in voice-related revenues by Mobile Network Operators (MNO) and the consequent rise in mobile data traffic. In this context, this paper aims to contribute to the literature on Strategic Technology Management by proposing an interpretative framework to support strategic decision making in dynamic, competitive contexts characterized by disruptive changes in both technology and business dimensions. The proposed framework is based on empirical research conducted at the four MNOs operating in Italy and allows identifying drivers of potentially disruptive change and their implications on a firm’s business model. The framework use is illustrated through the analysis of the Italian Mobile Telephony industry. Finally, the research also highlighted the main strategic routes MNOs have at their disposal to face the turbulent competitive times ahead. These include specific strategic actions to cope with the issues of mobile bandwidth scarcity and decreasing voice-related revenues. A summary of MNOs future strategic positioning options is also","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123633448","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, traditional close-up observations can interfere on the behaviour, and taking biometric measurements requires the capture of individuals, which also causes stress. This paper describes an automatic motoring system for birds breeding in nest boxes. The main goal is to significantly increase the amount and quality of data acquired on bird behaviour without stressing the individuals or interfering. This system is based in an interconnected embedded sensor network, which permits sharing this valuable information with researchers all over the world through the internet. Each device of the network is a smart nest-box that allows a cross-validation of sensor information and data quality. This system has been evaluated for the specific case of a lesser kestrel breeding colony in Southern Spain. The lesser kestrel is an insectivorous migratory falcon that readily accepts nest-boxes. The system has been named HORUS and the results obtained from a year experiment demonstrate the efficiency of this approach.","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122219768","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}

It is often used to obtain QoS guarantees in packet switched communication systems. One issue of nowadays’ research is the applicability of NC for multiplexed flows, in particular, if the FIFO property cannot be assumed when merging the individual flows. If a node serves the different flows using another schedule than FIFO, the terms ’strict’ or ’non-strict’ service curves play an important role. In this paper, we are dealing with the problems of strict and non-strict service curves in connection with aggregate scheduling. In the literature, the strictness of the service curve of the aggregated flow is reported as a fundamental precondition to get a service curve for the single individual flows at demultiplexing, if the service node process the input flows in Non-FIFO manner. The important strictness-property is assumed to be a unique feature of the service curve alone. But we will show here that this assumption is not true in general. Only the connection with the concrete input allows to classify a service as curve strict or","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134502530","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, MANETs do not seem to effectively support multimedia applications and especially video transmission. In this work, we propose a cross-layer design that aims to improve the performance of video transmission using TCP Friendly Rate Control (TFRC). Our design provides priority to video packets and exploits information from the MAC layer in order to improve TFRC’s performance. The proposed cross-layer mechanism utilizes Signal to Noise Ratio (SNR) measurements along the routing path, in order to make the route reconstruction procedure more efficient. Simulation results show that both the use of traffic categorization and the SNR utilization lead to important improvements of video transmission over the mobile Ad hoc network. More specifically, simulations indicate increased average Peak Signal to Noise Ratio (PSNR) for the received video, increased throughput and packet delivery ration, as well as reduced average end-to-end delay.","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115799048","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 many applications, XML files are transferred in a form of continuous streams. For example, in publishing- subscription systems, data is recorded in an XML format and the conditions of the user's subscription are expressed as queries. Thus, how to filter a continuous stream of XML documents against a large number of queries is an important issue. In this paper, we proposed an efficient filter called EFilter to support twig query patterns in XML streams. Users' queries are recorded in a compressed tree structure called Query Guide and a hash table called QLinkedList. Through a bottom-up search of Query Guide, the XML documents are processed only once as they arrive. Experimental results show that EFilter is more efficient than FiST (Kwon et al., 2005) and SFilter (Nizar, Babu and Kumar, 2009) in terms of filtering speed.","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126141799","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 means that besides the quality of the final product, the quality of the production processes is also of high interest. In this paper an overview concerning a three years study is given, in which a methodology for a continuous improvement of the geographic information production processes has been developed and applied. Also key figures to describe the quality of products and processes have been suggested. These key figures have been analyzed over a longer period.
