    Transformation in a Housing-Design Story: Reading the Spatial Typologies of Apartment Projects in Hatay-Izmir
    (İstanbul Teknik Üniversitesi, 2018) Yaylalı Yıldız, Berna; Ek, Fatma İpek; Can, Işın
    The politics of central government or incentives determine new design-systems of housing plots as well as housing units. Especially after the enactment of the law of urban regeneration for risky areas, regeneration of areas under disaster risk, there has been an acceleration in knocking down old buildings and constructing new ones in inner cities. Thus, this paper focuses on the changes in housing typologies in Hatay-Izmir, in terms of space syntax parameters through the time period 1960-2000, and interprets the final plan-solutions within the perspective of urban regeneration. By accelerating implementations of the urban transformation projects in Hatay region, alternative plan-typologies coming from the past have undergone the so-called “re-design and transformation” process; however, they have actually been substituted by the “never-changing” plan-templates of the apartment typology. We will examine these changes in plan typologies and spatial organisations of the mentioned apartment-projects on the same plots by utilizing the method of space syntax and visibility analysis (VGA). Transformations in spatial configuration in two periods are interpreted through their relationships to shifts in meaning of privacy and daily life represented by degree of permeability and connectivity of housing-unit-plans based on spatial analysis. © 2018, Istanbul Teknik Universitesi, Faculty of Architecture.

    Privacy-Preserving Targeted Advertising Scheme for Iptv Using the Cloud
    (SciTePress, 2012) Khayati, Leyli Javid; Savaş, Erkay; Ustaoğlu, Berkant; Örencik, Cengiz
    In this paper, we present a privacy-preserving scheme for targeted advertising via the Internet Protocol TV (IPTV). The scheme uses a communication model involving a collection of viewers/subscribers, a content provider (IPTV), an advertiser, and a cloud server. To provide high quality directed advertising service, the advertiser can utilize not only demographic information of subscribers, but also their watching habits. The latter includes watching history, preferences for IPTV content and watching rate, which are published on the cloud server periodically (e.g. weekly) along with anonymized demographics. Since the published data may leak sensitive information about subscribers, it is safeguarded using cryptographic techniques in addition to the anonymization of demographics. The techniques used by the advertiser, which can be manifested in its queries to the cloud, are considered (trade) secrets and therefore are protected as well. The cloud is oblivious to the published data, the queries of the advertiser as well as its own responses to these queries. Only a legitimate advertiser, endorsed with a so-called trapdoor by the IPTV, can query the cloud and utilize the query results. The performance of the proposed scheme is evaluated with experiments, which show that the scheme is suitable for practical usage.
