CA-ARBAC: privacy preserving using context-aware role-based access control on Android permission system

Existing mobile platforms are based on manual way of granting and revoking permissions to applications. Once the user grants a given permission to an application, the application can use it without limit, unless the user manually revokes the permission. This has become the reason for many privacy problems because of the fact that a permission that is harmless at some occasion may be very dangerous at another condition. One of the promising solutions for this problem is context-aware access control at permission level that allows dynamic granting and denying of permissions based on some predefined context. However, dealing with policy configuration at permission level becomes very complex for the user as the number of policies to configure will become very large. For instance, if there are A applications, P permissions, and C contexts, the user may have to deal with A × P × C number of policy configurations. Therefore, we propose a context-aware role-based access control model that can provide dynamic permission granting and revoking while keeping the number of policies as small as possible. Although our model can be used for all mobile platforms, we use Android platform to demonstrate our system. In our model, Android applications are assigned roles where roles contain a set of permissions and contexts are associated with permissions. Permissions are activated and deactivated for the containing role based on the associated contexts. Our approach is unique in that our system associates contexts with permissions as opposed to existing similar works that associate contexts with roles. As a proof of concept, we have developed a prototype application called context-aware Android role-based access control. We have also performed various tests using our application, and the result shows that our model is working as desired

Klişelerden uzak bir köy romancısı : Abbas Sayar

Ankara : Bilkent Üniversitesi Ekonomi ve Sosyal Bilimler Enstitüsü, Türk Edebiyatı Bölümü, 2002.Thesis (Master's) -- Bilkent University, 2002.Includes bibliographical references leaves 66-70.One of the most controversial literary subjects in Turkey between 1950s and 1970s was village literature, a specific genre that refers to the realistic works of Village Institute authors. These works, generally focused on economic and social problems of villagers, have been criticized for having too many stereotypical elements. Therefore, authors, whose fictions are based on village, are not literarily appreciated, regarded simply as village writers. Among those is Abbas Sayar (1923-1999), the author of novels entitled Can Şenliği (1974), Çelo (1972), Dik Bayır (1977), and Yılkı Atı (1970) among others. As a village-rooted novelist, the themes of his novels are on life in Central Anatolia and the language of these works contains idioms, proverbs, and accents of this region. Yet, he also pays attention to the original sides of his subject matters and establishes his novels skillfully. Hence, on the one side, he can be classified as a village writer. On the other side, he differs from other village writers in his literary methods. In this thesis, the place of Abbas Sayar’s works in village literature is detected and the original aspects of his novels are exemplified.Tomur, SevilM.S

A Paradigm for Safe Adaptation of Collaborating Robots

The dynamic forces that transit back and forth traditional boundaries of system development have led to the emergence of digital ecosystems. Within these, business gains are achieved through the development of intelligent control that requires a continuous design and runtime co-engineering process endangered by malicious attacks. The possibility of inserting specially crafted faults capable to exploit the nature of unknown evolving intelligent behavior raises the necessity of malicious behavior detection at runtime.Adjusting to the needs and opportunities of fast AI development within digital ecosystems, in this paper, we envision a novel method and framework for runtime predictive evaluation of intelligent robots' behavior for assuring a cooperative safe adjustment

The effects of cyclophosphamide and its uroprotective agents, mesna and hyperbaric oxygen, on urinary bladder motility in guinea pigs

The aim of this research was to observe the effects of cyclophosphamide and its uroprotective agents, mesna and hyperbaric oxygen (HBO), on the motility of urinary bladder muscle in guinea pigs. In the experimental groups, mesna and cyclophosphamide were intraperitoneally injected at a dose of 21.5 mg/kg and 68.1 mg/kg, respectively. For the combination of mesna and cyclophosphamide, one dose of mesna was injected 20 min before cyclophosphamide administration and three additional injections of mesna were repeated every three hours. A total of 8 HBO exposures were performed at 2.8 ATA for 90 min twice daily for another experimental group. In the HBO and cyclophosphamide combined group 5 HBO exposures were given prophylactically before cyclophosphamide. The combination of mesna, HBO and cyclophosphamide was administered by the same procedure. The contractions obtained in response to acetylcholine (ACh, 10–4M) in the control group were reduced using cyclophosphamide and HBO individually, but not by mesna. However, the contractions belonging to the various combinations of these three agents were not different from those seen in the control group. On the other hand, the combinations of cyclophosphamide, mesna and HBO showed higher responses to ACh than the groups in which cyclophosphamide and HBO were used individually, while the responses elicited by the cyclophosphamide and HBO combination were greater than those seen in the group treated with HBO only
