Using ontologies for modeling context-aware services platforms

This paper discusses the suitability of using ontologies for modeling context-aware services platforms. It addresses the directions of research we are following in the WASP (Web Architectures for Services Platforms) project. For this purpose a simple scenario is considered

The tropospheric gas composition of Jupiter's north equatorial belt (NH3, PH3, CH3D, GeH4, H2O) and the Jovian D/H isotropic ratio

The gas composition of the troposphere of Jupiter in the clearest regions of the North Equatorial Belt (NEB) was derived from the Voyager 1 IRIS data. The infrared spectrum for this homogeneous cloud free region was modeled to infer altitude profiles for NH3, PH3, GeH4 and H2O. The Profiles for NH3 and PH3 were found to be depleted in the upper troposphere but otherwise in agreement with their solar values at the 1 bar level. The mole fraction for CH3D was determined to be 3.5(+1.0 or -1.3) x 10 to the minus 7th power. The GeH4 mole fraction of 7+ or -2 x 10 to the minus 10th power at the 2 to 3 bar level is a factor of 10 lower than the solar value. The H2O mole fraction is approximately 1 x 0.00001 at the 2.5 bar level and is increasing to approximately 3 x 0.00001 at 4 bars where it is a factor of 30 lower than solar. Using IRIS infrared values for the mole fractions of CH3D and CH4 a value of D/H = 3.6(+1.0 or -1.4)x 0.00001 is derived. Assuming this Jovian D/H ratio is representative of the protosolar nebula, and correcting for chemical galactic evolution, yields a value of 5.5 - 9.0 x 0.00001 for the primordial D/H ratio and an upper limit of 1.8 to 2.4 x 10 to the minus 31st power cu cm for the present day baryon density

Alasan Rusia Melibatkan Diri dalam Konflik Bersenjata Suriah Tahun 2011-2015

Arab Spring which was happened in 2011 had ceated nationwide protest movement of the Syrian people to throw the regime of the President Bashar Al Assad. The conflict that was, at first,only protest then turned into armed conflict where the government, opposition and terrorism groups such as ISIS and Jabhat Al Nusra involved. The number of the deaths caused by the conflict were then called by the UN as crime against humanity. The UN initiated Geneve Peace Talks as an agenda to hold a political transition towards Bashar Al Assad's regime. The effort was rejected by Russia Federation. In 2013, the U.S. and its alliance deployed its miltary forces in Syria to suport opposition group while in 2015 Russia then responded to the U.S. action by deploying its military troops in order to support the regime of Bashar Al Assad. This research is aimed to explain the motives of why Russia involved in the Syrian armed conflict. The research used qualitative method and Offensive Realism Theory by John J. Mearsheimer. The result of this research is that the involvement of Russia was meant to exercise its geopolitical influence in the Middle East and to repress the expansion of U.S. influence in Syria

Kerjasama UNODC – Indonesia Dalam Memerangi Perdagangan Manusia Periode 2007-2013

The impact of technological advancement does not always has apositive effect. For example, one of the negative impact is the growingforms of transnational crime such as human trafficking. As onecontinent from five continents in the world, Asia is the region with thenumber of victims of human trafficking at most. Indonesia is one ofAsian countries which has become a source, destination, and transit ofhuman trafficking. Surely the Government of Indonesia continues tostrive to combat human trafficking in various ways, one of them ispartnership with UNODC. This thesis aims to determine the form ofthe partnership between the Government of Indonesia with theUNODC in combating human trafficking with period 2007-2013. Inthis thesis, author use the theory of Liberalism Institutionalism,because it is considered the most appropriate theory to explain thecooperation between the Government of Indonesia and UNODC. Inthis thesis, author use descriptive-explanative research type to explainand to describe the phenomenon of human trafficking in Indonesia.The results from this research is that the cooperation between theGovernment of Indonesia and UNODC are effective and inaccordance with the needs of the Government of Indonesia especiallyon the aspect of capacity building of Indonesian law enforcementofficial. However, the result from this cooperation does not give apositive implication for the reduction of the number of victims ofhuman trafficking in Indonesia

Towards a norm-driven design of context-aware e-health applications

In this paper, we explore the usefulness of elaborating process models with norms, especially focusing on the Norm Analysis Method (NAM) as an elaboration tool that can be combined with a process modeling tool, such as Petri Net (PN). The PN-NAM combination has been particularly considered in the paper in relation to a challenge that concerns the design of context-aware applications, namely the challenge of specifying and elaborating complex behaviors that may include alternative (context-driven) processes (we assume that a user context space can be defined and that each context state within this space corresponds to an alternative application service behavior). Hence, the main contribution of our paper comprises an adaptability-driven methodological and modeling support to the design of context-aware applications; modeling guidelines are proposed, considered together with corresponding modeling tools (in particular PN and NAM), and partially illustrated by means of an e-Health-related example. Given the multi-disciplinary nature of the e-Health domain, it is expected that the current research will be useful for it. In particular, e-Health system developers might benefit from the relevant methodological and modeling support, proposed in the paper

Contact binaries with additional components. III. The adaptive optics detections

We present results of the CFHT adaptive optics search for companions of a homogeneous group of contact binary stars, as a contribution to our attempts to prove a hypothesis that these binaries require a third star to become so close as observed. In addition to companions directly discovered at separations of >=1", we introduced a new method of AO image analysis utilizing distortions of the AO diffraction ring pattern at separations of 0.07"-1". Very close companions, with separations in the latter range were discovered in systems HV Aqr, OO Aql, CK Boo, XY Leo, BE Scl, and RZ Tau. More distant companions were detected in V402 Aur, AO Cam, V2082 Cyg. Our results provide a contribution to the mounting evidence that the presence of close companions is a very common phenomenon for very close binaries with orbital periods <1 day.Comment: Full Figs.4 and 5 are in http://www.astro.utoronto.ca/~rucinski/Triples3

Services Platforms for Context-Aware Applications

Context-aware services platforms aim at supporting the handling of contextual information in order to provide better user-tailored services. This paper addresses our current efforts towards a configurable and extensible services platform for context-aware applications. It discusses the use of a language and ontologies to cope with configurability and extensibility aspect

Geophysical surveys at Machu Picchu, Peru: Results for landslide hazard investigations

Geophysical methods are being used more frequently to assess slopes for landslide hazard potential, especially in areas where traditional methods such as trenching and drilling are either difficult to employ or not allowed. This paper presents the results of joint DC resistivity and EM surveys to map fractures and zones of weakness in crystalline bedrock at Machu Picchu, Peru. DC resistivity surveys were carried out along the upper 8 switchbacks leading to the sanctuary as well as across the sanctuary. EM-34 surveys were carried out along the upper 3 switchbacks and across the sanctuary. Inversion of the resistivity data located several lower resistivity zones along the switchbacks. These zones were associated with water seeping out of the rock in ditches. The water is confined to the upper switchbacks which is consistent with the disappearance of lower resistivity zones in the lower switchbacks. EM-34 results along the switchbacks, although more subtle to recognize, located several coincident zones of lower resistivity. The DC resistivity data across the sanctuary located a lower resistivity zone on the east side of the main plaza. There is presently no information on whether any of these fractures have been active in the recent past. Consequently the results from this study are still under investigation

Geophysical surveys at Machu Picchu, Peru: Results for landslide hazard investigations

Geophysical methods are being used more frequently to assess slopes for landslide hazard potential, especially in areas where traditional methods such as trenching and drilling are either difficult to employ or not allowed. This paper presents the results of DC resistivity, electromagnetic (EM ) and ground penetrating radar (GPR) surveys to map fractures and zones of weakness in crystalline bedrock at Machu Picchu, Peru. DC resistivity surveys were carried out along the upper 8 switchbacks of the Hiram Bingham road leading to the sanctuary as well as across the sanctuary. EM surveys were carried out along the upper 3 switchbacks and across the sanctuary. EM surveys were carried out at several other locations within the sanctuary but the data were not sufficient to allow detailed interpretations. GPR surveys were carried out over the main and lower plaza areas. Inversion of the resistivity data located several lower resistivity zones along the switchbacks. These zones were associated with water seeping out of the rock in ditches. The water is confined to the upper switchbacks which was consistent with the disappearance of lower resistivity zones in the lower switchbacks. EM results along the switchbacks, although more subtle to recognize, located several coincident zones of lower resistivity. The GPR data provided information on the unconsolidated sediment above bedrock and the bedrock topography within the plazas. There is presently no evidence on whether any of the mapped fractures have been active in the recent past
