The vehicular Ad-hoc network, or VANET, is for sharing of emergency and safety information among vehicles to ensure safe travelling of users in road. It is the technology that uses moving cars as nodes to create a mobile network, VANET turns every participating car into wireless router or node, allowing cars to establish communication. Vehicles can communicate within themselves (V2V) and also with the road side units (V2I).Vehicles communicating with other vehicles are expected to have the potential to enhance the driving experience, awareness, situation perception and thus safety.Cognitive Radio Network is employed in VANET for the efficient use of spectrum and to overcome spectrum scarcity. With growing interests in using CR technology in wireless communication systems for vehicles, it is envisioned that future vehicles will be CR enabled. The CR-VANET faces many issues and challenges in spectrum sensing, MAC protocols, Routing Protocols and Security. Among them we concentrate on spectrum sensing and routing in this project. We found out the spectrum for vehicular communication in scarce and vehicle density increasing scenario and the conventional routing protocols are of no use.

Das Ad-hoc-Netzwerk f r Fahrzeuge (VANET) dient dem Austausch von Notfall- und Sicherheitsinformationen zwischen Fahrzeugen, um eine sichere Fahrt der Verkehrsteilnehmer zu gew hrleisten. Es ist eine Technologie, die fahrende Autos als Knoten verwendet, um ein mobiles Netzwerk zu schaffen. VANET macht jedes teilnehmende Auto zu einem drahtlosen Router oder Knoten, der es den Autos erm glicht, Kommunikation herzustellen. Es wird erwartet, dass Fahrzeuge, die mit anderen Fahrzeugen kommunizieren, das Potenzial haben, das Fahrerlebnis, das Bewusstsein, die Situationswahrnehmung und damit die Sicherheit zu verbessern.Cognitive Radio Network wird in VANET f r die effiziente Nutzung des Spektrums und zur berwindung der Frequenzknappheit eingesetzt. Durch das wachsende Interesse an der Verwendung von CR-Technologie in drahtlosen Kommunikationssystemen f r Fahrzeuge, ist vorgesehen, dass zuk nftige Fahrzeuge CR-f hig sein werden. Das CR-VANET steht vor vielen Problemen und Herausforderungen in den Bereichen Spectrum Sensing, MAC-Protokolle, Routing-Protokolle und Sicherheit. In diesem Projekt konzentrieren wir uns auf Spectrum Sensing und Routing. Wir haben herausgefunden, dass das Spektrum f r die Fahrzeugkommunikation knapp ist und die Fahrzeugdichte zunimmt und die konventionellen Routing-Protokolle unbrauchbar sind.

NLOS nodes under emergency situation need to be effectively localized for supporting the vehicle under emergency to deliver essential information to the target vehicles in the stipulated time period. However, the majority of the existing NLOS localization incur huge overhead and time delay with reduced degree of channel utilization. In this research, three NLOS localization approaches that concentrate on range-based, range-optimizations and range-free detection process with an integrated framework are proposed for minimizing the overhead and time delay with maximized channel utilization rate.

The recent history of cultural exchange between France and the United States would appear to be defined by "freedom fries" and boycotts against Beaujolais - or, on the other side of the Atlantic, by enraged farmers toppling statues of Ronald McDonald. This dismal state of affairs is a long way from the mutual admiration that followed World War II, epitomized in a 1958 cover of "Look" magazine that declared "Brigitte Bardot conquers America." "It's So French!" explores the close affinity between the French and American film industries that flourished in the postwar years, breaking down myths of American imperialism and French cultural protectionism while illuminating the vital role that cinema has played in the globalization of culture. Hollywood was once enamored with everything French, and this infatuation blossomed in a wildly popular series of films, including "An American in Paris", "Gigi", and "Funny Face". Vanessa R. Schwartz here examines the visual appeal of such films and then broadens her analysis to explore their production and distribution, probing the profitable influences that Hollywood and Paris exerted on each other. This exchange moved beyond individual films with the sensational spectacle of the Cannes Film Festival and the meteoric career of Brigitte Bardot. And in turn, their success led to a new kind of film that celebrated internationalism and cultural hybridity. Ultimately, Schwartz uncovers an intriguing paradox: that the road to globalization was paved with nationalist cliches, and thus, films beloved for being so French were in fact the first signs of a nascent cosmopolitan culture. Packed with an array of colorful film stills, publicity photographs, paparazzi shots, ads, and never-before-seen archival images, "It's So French!" is an incisive account of the fertile collaboration between France and the United States that expanded the geographic horizons of both filmmaking and filmgoing, forever changing what the world saw and dreamed of when it went to the movies.
A stunning look at the profound impact of the jet plane on the mid-century aesthetic, from Disneyland to Life magazine Vanessa R. Schwartz engagingly presents the jet plane’s power to define a new age at a critical moment in the mid-20th century, arguing that the craft’s speed and smooth ride allowed people to imagine themselves living in the future. Exploring realms as diverse as airport architecture, theme park design, film, and photography, Schwartz argues that the jet created an aesthetic that circulated on the ground below. Visual and media culture, including Eero Saarinen’s airports, David Bailey’s photographs of the jet set, and Ernst Haas’s experiments in color photojournalism glamorized the imagery of motion. Drawing on unprecedented access to the archives of The Walt Disney Studios, Schwartz also examines the period’s most successful example of fluid motion meeting media culture: Disneyland. The park’s dedication to “people-moving” defined Walt Disney’s vision, shaping the very identity of the place. The jet age aesthetic laid the groundwork for our contemporary media culture, in which motion is so fluid that we can surf the internet while going nowhere at all.
This text examines the popularity in Paris of phenomena such as boulevards, the mass press and wax museums during the second half of the 19th century. It argues that "spectacular realities" helped create modern mass society and that instead of leading to alienation they united crowds in pleasure.
By combining the spirit of fiction with the fabulism of Indian mythology and in-depth academic research, Vanessa R. Sasson shares the evocative story of the Buddha from the perspective of a forgotten woman: Yasodhara, the Buddha’s wife. Although often marginalized, Yasodhara’s narrative here comes to life. Written with a strong feminist voice, we encounter Yasodhara as a fiercely independent, passionate and resilient individual. We witness her joys and sorrows, her expectations and frustrations, her fairy-tale wedding, and her overwhelming devastation at the departure of her beloved.It is through her eyes that we witness Siddhattha’s slow transformation, from a sheltered prince to a deeply sensitive young man. On the way, we see how the gods watch over the future Buddha from the clouds, how the king and his ministers try to keep the suffering of the world from him and how he eventually renounces the throne, his wife and newly-born son to seek enlightenment. Along with a foreword from Wendy Doniger, the book includes a scholarly introduction to Yasodhara’s narrative and offers extensive notes along with study questions, to help readers navigate the traditional literature in a new way, making this an essential book for anyone wanting to learn about Buddhist narratives.
