Vereins zur wissenschaftlichen Weiterbildung der Universitat
Mannheim e.V. die deutschsprachige Supercomputergemeinde -
Anwender, Betreiber, Hersteller - zu einem fruchtbaren Dialog und
Erfahrungsaustausch. In dem diesjahrigen Seminar "Supercomputer -
Anwendungen, Architekturen und Trends" werden die neuesten
Entwicklungen dieses stark innovativen Gebiets unter einem sehr
anwendungsbezogenen, praktischen Aspekt aufgearbeitet. Experten aus
dem Inland sowie den nach wie vor fuhrenden Landern USA und Japan
konnten auch bei dieser zum vierten Mal stattfindenden
Veranstaltung zu Prasentationen gewonnen werden. Alle Beitrage zum
Seminar sind in diesem Band enthalten. Insbesondere befassen sie
sich mit folgenden Schwerpunkten: -
Visualisierung/Mensch-Maschine-Schnittstelle - Architekturen -
Parallel versus vector processing - Innovative Anwendungen."
The cheap mobile phone is arguably the most significant personal
communications device in history. In India, where caste hierarchy
has reinforced power for generations, the disruptive potential of
the mobile phone is even more striking than elsewhere. In 2001,
India had 35 million telephones, only four million of them mobiles.
Ten years later, it had more than 800 million phone subscribers;
more than 95 per cent were mobile phones. In a decade,
communications in India have been transformed by a device that can
be shared by fisherfolk in Kerala, boatmen in Banaras, great
capitalists in Mumbai and power-wielding politicians and
bureaucrats in New Delhi. Village councils banned unmarried girls
from having mobile phones. Families debated whether new brides
should surrender them. Cheap mobile phones became photo albums,
music machines and radios. Religious images and uplifting messages
flooded tens of millions of phones each day. Pornographers and
criminals found a tantalising new tool. In politics, organisations
with cadres of true believers exploited a resource infinitely more
effective than telegrams, postcards and the printing press for
carrying messages to workers, followers and voters. Jeffrey and
Doron focus on three groups - controllers: the bureaucrats,
politicians and capitalists who wrestle over control of radio
frequency spectrum; servants: the marketers, agents, technicians,
tower-builders, repairers and second-hand dealers who carry mobile
phones to the masses; and users: the politicians, activists,
businesses and households that adapt the mobile phone to their
needs. The book probes the whole universe of the mobile phone -
from the contests of great capitalists and governments to control
radio frequency spectrum, to the ways ordinary people build the
troublesome and addictive device into their daily lives.
As the internet of things market is booming, several issues are
delaying the full realization of the technology. Currently,
business competitors are jockeying for a piece of the market,
meaning solutions from researchers that address these issues is
crucial for internet of things technology developers. Overpromising
followed by underdelivering has been the current approach by many
innovators, and the mismatch results in losses in production,
orphaned technologies, and frequent system failures. Solutions that
address internet of things performance issues must be studied in
order to take full advantage of this emerging market. Achieving
Full Realization and Mitigating the Challenges of the Internet of
Things addresses the challenges faced in rolling out internet of
things technologies as well as the various performance issues.
Covering a range of topics such as cybersecurity and connectivity
issues, this reference work is ideal for industry professionals,
academicians, researchers, practitioners, technology developers,
instructors, and students.
Ais ich dieses Buch im Jahre 1920 zum ersten lYIale herausgab,
folgte ich vielfach geapBerten Wiinschen, die von mir fiir die
Firma Siemens & Halske geschriebenen Technischen Anweisungen
iiber Wechselstrom-Leistungsmessungen weitesten Kreisen in
geschlossener Form zuganglich zu machen. Bei dieser Entwicklung
konnten naturgemaB nur Siemens-Apparate in dem Buch be schrieben
werden. Da diese jedoch nur als Ausfiihrungsbeispiele fiir den im
iibrigen allgemein behandelten Stoff dienen und sich die Fabrikate
anderer Firmen von den beschriebenen nicht prin zipiell, sondern
nur in konstruktiven Einzelheiten unterscheiden, ist die
Beschrankung auf ein Fabrikat belanglos. Diese Behand lungsweise
bietet vielmehr den Vorteil, daB das ganze Gebiet an einer
einheitlich durchgebildeten Reihe von MeBgeraten be sprochen werden
kann und daB statt allgemeiner Angaben iiberall festliegende Zahlen
gebracht werden konnen. Um den hierdurch gegebenen Gebrauchswert
des Buches zu erhalten, sind auch in der zweiten und in der
vorliegenden dritten Auflage als Aus fiihrungsbeispiele im
allgemeinen nur Siemens-MeBgerate gebracht. Im iibrigen ist jedoch
das Buch seit dem ersten Erscheinen voll standig umgearbeitet
worden. In der vorliegenden drittw Auflage ist der Stoff nach
allgemein giiltigen Gesichtspunkten neu aufgebaut und gegliedert
worden. Hierdurch ergab sich die Moglichkeit, das Gemeinsame der
ver schiedenen MeBgerate zusammenzufassen und einheitlich zu be
handeIn. So wird beispielsweise erst die Bauart der verschiedenen
MeBwerke der Leistungsmesser geschlossen behandelt, dann werden die
Ausfiihrungsmoglichkeiten der Innenschaltung und endlich die fiir
die Messungen erforderliche Berechnung der Kon stanten in allgemein
geltender Form gebracht."

The wireless medium is a shared resource. If nearby devices
transmit at the same time, their signals interfere, resulting in a
collision. In traditional networks, collisions cause the loss of
the transmitted information. For this reason, wireless networks
have been designed with the assumption that interference is
intrinsically harmful and must be avoided. This book, a revised
version of the author's award-winning Ph.D. dissertation, takes an
alternate approach: Instead of viewing interference as an
inherently counterproductive phenomenon that should to be avoided,
we design practical systems that transform interference into a
harmless, and even a beneficial phenomenon. To achieve this goal,
we consider how wireless signals interact when they interfere, and
use this understanding in our system designs. Specifically, when
interference occurs, the signals get mixed on the wireless medium.
By understanding the parameters of this mixing, we can invert the
mixing and decode the interfered packets; thus, making interference
harmless. Furthermore, we can control this mixing process to create
strategic interference that allow decodability at a particular
receiver of interest, but prevent decodability at unintended
receivers and adversaries. Hence, we can transform interference
into a beneficial phenomenon that provides security. Building on
this approach, we make four main contributions: We present the
first WiFi receiver that can successfully reconstruct the
transmitted information in the presence of packet collisions. Next,
we introduce a WiFi receiver design that can decode in the presence
of high-power cross-technology interference from devices like baby
monitors, cordless phones, microwave ovens, or even unknown
technologies. We then show how we can harness interference to
improve security. In particular, we develop the first system that
secures an insecure medical implant without any modification to the
implant itself. Finally, we present a solution that establishes
secure connections between any two WiFi devices, without having
users enter passwords or use pre-shared secret keys.
