Facebook polls as proto-democratic instruments in the Egyptian revolution: The ‘We Are All Khaled Said’ Facebook page
No full textThis article examines the dynamics of political participation on the ‘We Are All Khaled Said’ Facebook page, which hosted the call for Egypt’s 25 January 2011 revolution. It shows that the page served as a proto-democratic instrument by introducing both qualitative and quantitative polls and following up with actions based on majority opinion. This argument is developed through an analysis of discussion threads and polls from the page, selected from a data set of 14,072 posts, 6,810,357 comments and 32,030,731 likes made by 1,892,118 users, extracted via a customized version of Netvizz. The analysis demonstrates that the page provided a basic lesson in democratic participation to its users. ‘We Are All Khaled Said’ constituted an unprecedented public space for active discussions on fighting corruption, torture and police brutality. Moreover, it served as a practical example of shared governance and political participation, which became a model for its users to strive to apply to their country
Multicore-scalable file system
No full textThesis: S.M., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2014.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 47-49).It is difficult to achieve durability and crash consistency in file systems along with multicore scalability. Commutative file system operations, which should scale according to the Scalable Commutativity Property, conflict on shared resources like coarse-grained locks and pages present in the page cache or buffer cache. Furthermore, data structures that are on separate cache lines in memory (e.g., directory entries) are grouped together when the file system writes them to disk for durability. This grouping results in additional conflicts. This thesis introduces a new design approach that decouples the in-memory file system from the on-disk file system, using per core operation logs. This facilitates the use of highly concurrent data structures for the in-memory representation, which is essential for commutative operations to proceed conflict free and hence scale perfectly. The in-memory representation does not propagate updates to the disk representation immediately, instead it simply logs the operation in a per core logical log. A sync or an fsync call processes these operations and applies them to the disk. Techniques based on time stamping linearization points of file system operations ensure crash consistency, and dependency tracking ensures good disk performance. A prototype file system, SCALEFS, implements this new approach and techniques. Experiments using COMMUTER and SCALEFS show that the implementation is conflict free for 99% of test cases involving commutative operations.by Rasha Eqbal.S.M
Communicating Cosmopolitanism:An Analysis of the Rhetoric of Jimmy Carter, Vaclav Havel, and Edward Said
No full textThis project explores how cosmopolitan personas rhetorically negotiate the space between local and global, discursively tying people to the national as well as to the global or transnational. It examines the possible co-existence of cosmopolitanism and nationalism while identifying how each is articulated in response to the other. As global networks become increasingly complex, rethinking borders and how they are articulated is essential. Can a quintessential cosmopolitan also be a public nationalist? Are cosmopolitan discourses compromised by their presumed lack of attachment to the local? To what extent and with what success are cosmopolitanism and nationalism siultaneously articulated? In order to study these and other questions, I analyze the public personas crafted by cosmopolitan figures Vaclav Havel, Jimmy Carter, and Edward Said. By illuminating how they negotiate that ambiguous space between locale and its absence, a project attentive to the rhetorical possibilities of discursive connection in a world increasingly devoid of shared loyalties and histories enables a fuller understanding of the possibilites of intercultural contact in a globalizing world

Affordable sustainable earthbag housing; achieving indoor thermal comfort in low cost housing in Egypt
No full textAssessment Of GNSS Positioning Techniques In EGYPT
No full textThis research delves into Global Navigation Satellite Systems (GNSS) positioning accuracy, focusing on GPS, GLONASS, and their combined utility to evaluate GLONASS as an independent system in case GPS is down. The study spans three phases. First, data from stations located in Port Said, analyzed using relative positioning technique, GPS shows an average coordinate deviation of 0.32 millimeters for GPS-only scenarios, while GLONASS exhibits 1.045 millimeters for GLONASS-only scenarios. Merging both narrows this gap, especially in shorter baselines. Second, an extensive dataset over three years from eight Egyptian stations, using GPS and GLONASS as references, shows that GPS consistently provides better three-dimensional accuracy in most stations with close values. Finally, employing Precise Point Positioning (PPP) techniques, the study rigorously compares three processing software solutions (PPPH, PPP-ARISEN, PRIDE-PPPAR) with the same dataset. PRIDE-PPPAR closely aligns with BERNESE software accuracy, followed by PPP-ARISEN and PPPH. These findings suggest that GLONASS alone can be used for many applications, and open-source PPP software can be employed with acceptable accuracy

Medinet Habu and Western Thebes’s Sacred Landscape: Traditional Identity Multifaceted Through Time
No full textWestern bank of Modern Luxor is distinguished by its rich ancient monumental remains. Both banks of Ancient Thebes formed the sacred landscape of Amun-Re home city. That ancient landscape carried a traditional heritage which formed its spiritual identity, an identity that was manifested in spaces and constructions. The ancient western bank was an administrational center as well as a great necropolis. The royal temples were constructed near the foot of the Theban Hills, they still mark the western edge of the floodplain of contemporary Western Luxor, those temples linked the divine rulers, the universal god, and the traditional cosmic concepts until the Roman times. When the Coptic transformation took its turn, it transformed the ancient constructions to suit the new national identity, which is Coptic Egypt. But the traditional identity was not lost, and the interaction between Christianity and the sacred landscape was mutual. For understanding the complications of Western Thebes’s changes through time, Medinet Habu complex will be the focus of this paper, it was built by Ramses III and dedicated to Amun-Re and the Ogdoad, the complex was linked ritually with Luxor Temple in Eastern Thebes by ancient festivals, playing an essential role in the traditional cosmic vision. Medinet Habu also served as an administrative, political center, and a fortified site. It provided security during times of unrest. It kept growing until the Ptolemaic dynasties rule, and later, it became a Coptic center known as the Holy Mount of Djeme. The paper is a comprehensive research for the interpretation of the meaning of Habu Complex location, original features, and transformation. The monument story was part of a whole sacred landscape transformation process. The narration timeline covers exploring the ancient cultural features of western Thebes, since the Old Kingdom, and until Late antiquity. The paper is using thematic analysis of the data which was collected from various resources, such as archaeological evidence, ethnographic descriptions, iconographic representations, and Spatial information
