Benefits of InterSite Pre-Processing and Clustering Methods in E-Commerce Domain

This paper presents our preprocessing and clustering analysis on the clickstream dataset proposed for the ECMLPKDD 2005 Discovery Challenge. The main contributions of this article are double. First, after presenting the clickstream dataset, we show how we build a rich data warehouse based an advanced preprocesing. We take into account the intersite aspects in the given ecommerce domain, which offers an interesting data structuration. A preliminary statistical analysis based on time period clickstreams is given, emphasing the importance of intersite user visits in such a context. Secondly, we describe our crossed-clustering method which is applied on data generated from our data warehouse. Our preliminary results are interesting and promising illustrating the benefits of our WUM methods, even if more investigations are needed on the same dataset

Improving the Performance of a Proxy Server using Web log mining

Web caching techniques have been widely used with the objective of caching as many web pages and web objects in the proxy server cache as possible to improve network performance. Web pre-fetching schemes have also been widely discussed where web pages and web objects are pre-fetched into the proxy server cache. This paper presents an approach that integrates web caching and web pre-fetching approach to improve the performance of proxy server’s cache

Security Enhanced Applications for Information Systems

Every day, more users access services and electronically transmit information which is usually disseminated over insecure networks and processed by websites and databases, which lack proper security protection mechanisms and tools. This may have an impact on both the users’ trust as well as the reputation of the system’s stakeholders. Designing and implementing security enhanced systems is of vital importance. Therefore, this book aims to present a number of innovative security enhanced applications. It is titled “Security Enhanced Applications for Information Systems” and includes 11 chapters. This book is a quality guide for teaching purposes as well as for young researchers since it presents leading innovative contributions on security enhanced applications on various Information Systems. It involves cases based on the standalone, network and Cloud environments

NEGOTIATING HOUSEHOLD QUALITY OF LIFE AND SOCIAL COHESION AT UCANHA, YUCATAN, MEXICO, DURING THE LATE PRECLASSIC TO EARLY CLASSIC TRANSITION

The main focus of this project is to chronicle whether or not social inequality increased among households and community-level interactions in Ucanha, Yucatan, Mexico, at the time it was physically integrated with a larger regional polity headed by Ucí around the Terminal Preclassic/Early Classic (50 BCE – CE 400) transition. My research seeks to identify how social distinctions emerged during the early moments of social inequality and how these distinctions did or did not become a threat to social cohesion, as seen in the Early Classic “collapse” in some areas. Using a relational theoretical perspective, I argue that political authority and economic practices are embedded in moral expectations of a household quality of life that is negotiated by all actors. Trenching and broad-scale horizontal excavations document five variables of social distinction—architectural energetics, feasting, diversity of household assemblage, caching/burial practices, and the use of space—at three dwellings. Gini scores that calculate the distribution of fancy ceramics and labor investments in architecture also contribute to measuring household wellbeing at Ucanha. Results highlight differential, yet relatively high, quality of life during the Late Preclassic and then greater inequality and an overall decreased quality of life by the middle of the Early Classic (CE 400/450 – 600). Excavations from contexts associated with monumental architecture indicate vast labor inputs into Ucanha’s built landscape around the time of broader regional integration. Excavations and multi-elemental chemical analyses from the Central Plaza suggest this large public space was built during the Late Preclassic and was used for a variety of rituals that incorporated the populace through processions and performances. By the first few centuries into the Early Classic, however, the Central Plaza was walled off and access became limited and more tightly controlled. Thus, it appears emergent leaders at Ucanha, as evidenced by the presence of iconography related to centralized decision-making and possibly kingship, were successful in providing a high quality of life for their citizenry in exchange for labor and devoted followers during regional integration. Yet, during the Early Classic, household quality of life diminished, access to fancy ceramics became highly curtailed, and many residential platforms were abandoned likely as a result of leaders failing to meet the expectations of their followers

Earth Resources: A continuing bibliography with indexes

This bibliography lists 475 reports, articles and other documents introduced into the NASA scientific and technical information system between January 1 and March 31, 1984. Emphasis is placed on the use of remote sensing and geophysical instrumentation in spacecraft and aircraft to survey and inventory natural resources and urban areas. Subject matter is grouped according to agriculture and forestry, environmental changes and cultural resources, geodesy and cartography, geology and mineral resources, hydrology and water management, data processing and distribution systems, instrumentation and sensors, and economical analysis

The 1989 long-range program plan

The President's National Space Policy of 1988 reaffirms that space activities serve a variety of vital national goals and objectives, including the strengthening of U.S. scientific, technological, political, economic, and international leadership. The new policy stresses that civil space activities contribute significantly to enhancing America's world leadership. Goals and objectives must be defined and redefined, and each advance toward a given objective must be viewed as a potential building block for future programs. This important evolutionary process for research and development is reflected, describing NASA's program planning for FY89 and later years. This plan outlines the direction of NASA's future activities by discussing goals, objectives, current programs, and plans for the future. The 1989 plan is consistent with national policy for both space and aeronautics, and with the FY89 budget that the President submitted to Congress in February 1988

A state of change : an historical archaeology of Doukhobor identity at Kirilovka village site (FcNs-1)

A migration of over seven thousand Russian immigrants belonging to the Christian sect known as the Doukhobors arrived in western Canada beginning in early 1899. Three colonies of at least 61 villages in total were established in the Districts of Saskatchewan and Assiniboia in the Northwest Territories. Due to internal tensions in the sect and conflicts with the Department of the Interior, most of these villages were abandoned by 1920. Although the Doukhobors in Saskatchewan are an integral part of the province's agricultural and settlement history, no substantial archaeological investigation of village sites took place until the site of Kirilovka (FcNs-I) was excavated in August and September of 1996. Kirilovka village was located along the North Saskatchewan River, west of the community of Langham, and was occupied by 30-35 families at the peak of its population. An archaeological sample representing the locations of four households is investigated in this thesis. Historical characterizations of the Doukhobors in Saskatchewan tend to be uncertain as to whether the Doukhobors were an ethnic group and/or religious sect, and to the degree of internal cohesion and homogeneity at the community level. Combined archaeological and historical investigations here suggest that the Doukhobor identity in Saskatchewan cannot be defined simply in terms of Russian ethnicity, but involves a combination of philosophical, ethnic, economic, and geographical factors. Further, the Doukhobor identity is characterized by the constant change brought about through repeated mass migrations spanning two centuries. One of the material implication of this identity was a tendency to readily adopt certain new technologies and styles into Doukhobor activities. This thesis examines the possible social implication of such material acquisitions. Only further archaeological investigation of Saskatchewan Doukhobor village sites may contribute to or contradict the findings of this research. It is hoped, however, that this thesis provides a necessary contribution to the growing field of Settlement Period Archaeology in western Canada
