Submarine Navigation using Neutrinos

Neutrinos are among the most abundant particles in the universe, nearly massless, travel at speeds near the speed of light and are electrically neutral. Neutrinos can be generated through man-made sources like particle accelerators or by natural sources like the sun. Neutrinos only interact via the weak force and gravity. Since gravitational interaction is extremely weak and the weak force has a very short range, neutrinos can travel long distances unimpeded through matter, reaching places inaccessible to GNSS (Global Navigation Satellite System) signals such as underwater locations. The main objective of this work is to sketch an early high-level design of a Neutrino PNT (Position, Navigation and Timing) mission and analyze its feasibility for submarine navigation since there is a need to improve current navigation technologies for submarines. The high-level preliminary concept proposes Cyclotrons or Linear Accelerators based on the physical process Pion Decay at Rest as neutrino sources. For detecting such isotropic neutrino fluxes user equipment must be composed of a high-performance clock synchronized with the system, a detector and possibly additional sensors such as IMU (Inertial Measurement Unit). A feasibility analysis of the recommended system option is performed based on simulations for determining the neutrino detection rate and on a PNT tool to estimate the PNT performances. Although the submarine navigation application is in the limit of being feasible with current technology, it could be realized with some important but reasonable progress in source and neutrino detector technology.Comment: 10pages, 12 figure

Towards a hybrid simulation modelling framework for service networks

The increasingly globalized service-centric economy has brought much attention on the concept of service networks. Scientific disciplines, such as management and service oriented computing, have commenced studying on how to design, develop, manage, and govern service networks. What is really needed for service networks to be developed, provisioned and managed in practice, however, are disciplined methods and tools that are able to take into account, tune and reconcile both technical and business considerations. This paper may be seen as a first, yet critical step in realizing the above vision. In particular, this paper explores a hybrid service network simulation approach that is able to analyze, optimize and tune the performance of service networks and their resources, including software services and human operated services. Our holistic, hybrid simulation framework will be firmly grounded on pre-existing simulation techniques that have been widely used in process modelling and simulation

How to describe species richness patterns for bryophyte conservation?

A large amount of data for inconspicuous taxa is stored in natural history collections; however, this information is often neglected for biodiversity patterns studies. Here, we evaluate the performance of direct interpolation of museum collections data, equivalent to the traditional approach used in bryophyte conservation planning, and stacked species distribution models (S-SDMs) to produce reliable reconstructions of species richness patterns, given that differences between these methods have been insufficiently evaluated for inconspicuous taxa. Our objective was to contrast if species distribution models produce better inferences of diversity richness than simply selecting areas with the higher species numbers. As model species, we selected Iberian species of the genus Grimmia (Bryophyta), and we used four well-collected areas to compare and validate the following models: 1) four Maxent richness models, each generated without the data from one of the four areas, and a reference model created using all of the data and 2) four richness models obtained through direct spatial interpolation, each generated without the data from one area, and a reference model created with all of the data. The correlations between the partial and reference Maxent models were higher in all cases (0.45 to 0.99), whereas the correlations between the spatial interpolation models were negative and weak (-0.3 to -0.06). Our results demonstrate for the first time that S-SDMs offer a useful tool for identifying detailed richness patterns for inconspicuous taxa such as bryophytes and improving incomplete distributions by assessing the potential richness of under-surveyed areas, filling major gaps in the available data. In addition, the proposed strategy would enhance the value of the vast number of specimens housed in biological collections

Process-aware information systems for emergency management

Nowadays, Process-aware Information Systems (PAISs) are widely used in many business scenarios, e.g., by government agencies, by insurance companies, and by banks. Despite this widespread usage, the typical application of such systems is predominantly in the context of business scenarios. Nevertheless, emergency management can also benefit from the use of PAISs; for instance, the metaphor of a business process fits very good with the concept of emergency recovery plan. This paper summarizes an invited talk given by the first author for the EMSOA’10 workshop that has been co-located with the ServiceWave 2010 Conference. This paper starts the basic PAIS’ requirements for the domain of emergency management, then it gives an overview of the nowadays’ literature on using PAISs for Emergency Management. Finally, the paper proposes an architecture and a system to support the execution of emergency management processes

Managing RFID Sensors Networks with a General Purpose RFID Middleware

RFID middleware is anticipated to one of the main research areas in the field of RFID applications in the near future. The Data EPC Acquisition System (DEPCAS) is an original proposal designed by our group to transfer and apply fundamental ideas from System and Data Acquisition (SCADA) systems into the areas of RFID acquisition, processing and distribution systems. In this paper we focus on how to organize and manage generic RFID sensors (edge readers, readers, PLCs, etc…) inside the DEPCAS middleware. We denote by RFID Sensors Networks Management (RSNM) this part of DEPCAS, which is built on top of two new concepts introduced and developed in this work: MARC (Minimum Access Reader Command) and RRTL (RFID Reader Topology Language). MARC is an abstraction layer used to hide heterogeneous devices inside a homogeneous acquisition network. RRTL is a language to define RFID Reader networks and to describe the relationship between them (concentrator, peer to peer, master/submaster)
