SONoMA: A Service Oriented Network Measurement Architecture
Distributed network measurements are essential to characterize
the structure, dynamics and operational state of the Internet.
Although in the last decades several such systems have been
created, the easy access of these infrastructures and the
orchestration of complex measurements are not solved. We propose
a system architecture that combines the flexibility of mature
network measurement facilities such as PlanetLab or ETOMIC with
the general accessibility and popularity of public services like
Web based bandwidth measurement or traceroute servers. To
realize these requirements we developed a network measurement
platform, called SONoMA, based on Web Services and the basic
principles of SOA, which is a well established paradigm in
distributed business application development. Our approach opens
the door to perform atomic and complex network measurements in
real time, handles heterogeneous measurement devices,
automatically stores the results in a public database and
protects against malicious users as well. Furthermore, SONoMA is
not only a tool for network researchers but it opens the door to
developing novel applications and services requiring real-time
and large scale network measurements

ANALISIS KONSUMSI BAHAN BAKAR MOTOR BENSIN YANG TERPASANG PADA SEPEDA MOTOR SUZUKI SMASH 110CC YANG DIGUNAKAN PADA JALAN MENANJAK
This research aims to determine the fuel consumption of gasoline engine mounted on a 110cc Suzuki Smash. The data taken on the motorcycle in different gear ratios and speed for a travel distance of 1.4 km. Analysis was conducted on gear ratios-1, 2 and 3 at speeds of 10, 15, 20, 25,30,35 and 40 km / h. Observations and calculations for the a set of speed indicate that fuel consumption at gear ratio-1 is 539,9, 664,3, 770,1, 927,0, dan 989,8 g / h respectively. At gear ratio-2 is 506,8, 630,7, 730,4, 832,2 dan 982,0 g / h respectively. At gear ratio-3 is 421,7, 502,2, 558,1, 529,5 dan 721,0 g / h respectively. It is concluded that the higher the speed of the motor, the betterr the rate of consumption of fuel. From the observation it was found that the test was performed at the engine rotation range of 3210 to 6030 rpm. Results demonstrate that at the speed of 10 km / h to 40 km / h it is more efficient operate with gear ratio-2. Keywords: Fuel Consumption, Gasoline Motor, Suzuki Smash 110cc

And the first shall be the last
This study analyzes the puzzle of Hungarian economic drifting in a long run perspective. The underlying puzzle for the investigation is why bad policies are invariably popular and good policies unpopular, thus why political and economic rationality never overlap. The first part of the article summarizes in eight points the basic features of the postwar period. Then six lessons are offered, which might be useful for other countries in transition or for students of comparative economics and politics, lessons that can be generalized on the basis of the individual country experience

The Next Generation of Axion Helioscopes: The International Axion Observatory (IAXO)
The International Axion Observatory (IAXO) is a proposed 4th-generation axion helioscope with the primary physics research goal to search for solar axions via their Primakoff conversion into photons of 1 \u2013 10 keV energies in a strong magnetic field. IAXO will achieve a sensitivity to the axion-photon coupling ga\u3b3 down to a few
710 1212 GeV 121 for a wide range of axion masses up to 3c 0.25 eV. This is an improvement over the currently best (3rd generation) axion helioscope, the CERN Axion Solar Telescope (CAST), of about 5 orders of magnitude in signal strength, corresponding to a factor 3c 20 in the axion photon coupling. IAXO's sensitivity relies on the construction of a large superconducting 8-coil toroidal magnet of 20 m length optimized for axion research. Each of the eight 60 cm diameter magnet bores is equipped with x-ray optics focusing the signal photons into 3c 0.2 cm2 spots that are imaged by very low background x-ray detectors. The magnet will be built into a structure with elevation and azimuth drives that will allow solar tracking for 12 hours each day. This contribution is a summary of our papers [1], [2] and [3] and we refer to these for further details
