Aerogravity-assist maneuvering of a tethered satellite system

Two new implementations of a tethered satellite system to provide aeroassist during a planetary flyby are investigated. In each mission scenario the interaction of the Martian atmosphere with an aerodynamic lifting surface, which is tethered to an orbiter, is used to perturb the flight path of the system. The aerodynamic forces generated by interacting with the atmosphere augment the gravity assist provided by the planet. In the first aerogravity-assist maneuver the tethered satellite system has congruent post- and preflyby configurations. The second scenario, which is referred to as a dual-destination mission, involves the system mass being separated during the flyby. Both of these aerogravity-assist maneuvers are shown to facilitate significant, propellant-free velocity changes.

Prospective case review of a global e-health system for doctors in developing countries

The Swinfen Charitable Trust has managed email consultations for doctors in developing countries since 1999. The process was handled manually for the first three years and then subsequently using an automatic message-handling system. We conducted a prospective review of email consultations between referring doctors and consulting specialists during six months of automatic operation (December 2003 to May 2004). During the study period 125 consultations took place. These concerned a wide range of specialties (e.g. orthopaedics 17%, dermatology 16%, obstetrics and gynaecology 11%, radiology 10%). Of these referrals, 33% (41) were for paediatric cases. Consulting specialists, who were based in five countries, were volunteers. Referring doctors were from 24 hospitals in 12 developing countries. The median time from referral to definitive reply was 1.5 days (interquartile range 0.6-4.9). There was an 85% response rate (n = 106) to a survey concerning the value of the consultation to the referring doctor. All the referring doctors who responded made positive comments about the service and half said that it improved their management of the case. The second-opinion consultation system operated by the Swinfen Charitable Trust represents an example of a global e-health system operated for altruistic, rather than commercial, reasons.

Az átalakuló globális pénzügyi szabályozórendszer kérdései = Dilemmas of the changing global financial regulation system

Erősődő igény van a jelenlegi sokoldalú nemzetközi felügyeleti rendszer reformjára úgy, hogy az a nemzeti gazdaságpolitikák nemzetközi hatásait is figyelembe vegye. Ehhez át kell reformálni a jelenlegi globális pénzügyi szabályozási rendszert, de ki kell alakítani a nemzeti gazdaságpolitikák egymásra hatásának koordinációját is. Ide tartozik a globális külső sokkok csillapítására szolgáló anti-ciklikus finanszírozás, a nemzetközi adózási együttműködés fokozása, a nemzetközi adósságfinanszírozás tökéletesítése, vagy a globális fizetésieszköz-tartalékok és a fizetési rendszer viszonya. Ez utóbbi területen az SDR kiterjedtebb használatának feltételeit kell kimunkálni. A jelenlegi globális intézmények – WTO, Nemzetközi Valutaalap, Világbank – alapos megújítása elkerülhetetlen. A globális gazdasági koordináció intézményi kereteinek kidolgozása viszont még várat magára. A G20-ak csoportja – bár fontos reformokat kezdeményezett –, nem tekinthető a világgazdasági egyensúlytalanságok megoldása letéteményesének. A cél csak olyan globális intézményi struktúra lehet, amely egyaránt képes a világ nagy számú gazdaságai közötti koordinációs feladatok megoldására, s a döntések végrehajtásának kikényszerítésére. / === / The present multilateral international surveillance system needs to be reformed with an eye on international repercussions of national economic policies. The present global financial architecture, the coordination of interplays of national economic policies must be modified. An anti-cyclical financing capable of absorbing global external shocks, strengthening of international tax cooperation, improving international debt financing or the relations between global financial reserves and the global payment system might be part and parcel of this process. A more extended use of SDR could be worked out. Reforms of the present global institutions – the WTO, the IMF, the World Bank – cannot be avoided any further. Institutional frameworks of global economic coordination mechanism have still not been worked out. The Group of 20 (G-20) cannot be seen as the sole player in fighting world economic disequlibria. A global institutional system is envisaged, which is able to implement economic coordination among national economic units and to enforce the implementation of decisions taken. At present there is no global institution dealing with coherence and consistency of global issues. Reforming present institutions and/or designing new ones are possible options. The basis for such an international coordination must involve general acceptance of principles, transparent implementation, and enforcement of decisions taken.

Expanding a Global Company Management System to An Integrated Coverage of Several Standards

This Master’s thesis examines the implementation of management system standard requirements as integrated in the organization. The aim is to determine how requirements from management system standards ISO 14001:2015 and ISO 9001:2015 can be integrated and implemented into the existing ISO 9001:2008 compliant management system. Research was executed as action research by utilizing an operating model about the integrated use of management system standards created by the International Organization for Standardization. Phases of the operating model were applied to the target organization. The similarity and integration potential of relevant standards were assessed by using comparative matrices. Allocation of the requirements and conformity assessment of the processes was executed by gap analysis. The main results indicate that the requirements of the relevant standards are principally equivalent or have the same kind of purpose. The results also show the most important processes of the target organization in terms of requirement compliance, as well as the requirements which affect the process the most. Prioritizing the compliance achievement of the most important processes and implementation of those requirements that have the most effect create an opportunity for organizations to implement the integrated requirements effectively.

Mapping of use and occupation of the soil and irrigation water quality in the city of Salto do Lontra-Paraná, Brazil

The objective of this study consisted on mapping the use and soil occupation and evaluation of the quality of irrigation water used in Salto do Lontra, in the state of Paraná, Brazil. Images of the satellite SPOT-5 were used to perform the supervised classification of the Maximum Likelihood algorithm - MAXVER, and the water quality parameters analyzed were pH, EC, HCO3-, Cl-, PO4(3-), NO3-, turbidity, temperature and thermotolerant coliforms in two distinct rainfall periods. The water quality data were subjected to statistical analysis by the techniques of PCA and FA, to identify the most relevant variables in assessing the quality of irrigation water. The characterization of soil use and occupation by the classifier MAXVER allowed the identification of the following classes: crops, bare soil/stubble, forests and urban area. The PCA technique applied to irrigation water quality data explained 53.27% of the variation in water quality among the sampled points. Nitrate, thermotolerant coliforms, temperature, electrical conductivity and bicarbonate were the parameters that best explained the spatial variation of water quality.

A comment on the article “A collinearity diagnosis of the GNSS geocenter determination” by P. Rebischung, Z. Altamimi, and T. Springer

Meindl et al. (Adv Space Res 51(7):1047–1064, 2013) showed that the geocenter z -component estimated from observations of global navigation satellite systems (GNSS) is strongly correlated to a particular parameter of the solar radiation pressure (SRP) model developed by Beutler et al. (Manuscr Geod 19:367–386, 1994). They analyzed the forces caused by SRP and the impact on the satellites’ orbits. The authors achieved their results using perturbation theory and celestial mechanics. Rebischung et al. (J Geod doi:10.1016/j.asr.2012.10.026, 2013) also deal with the geocenter determination with GNSS. The authors carried out a collinearity diagnosis of the associated parameter estimation problem. They conclude “without much exaggerating that current GNSS are insensitive to any component of geocenter motion”. They explain this inability by the high degree of collinearity of the geocenter coordinates mainly with satellite clock corrections. Based on these results and additional experiments, they state that the conclusions drawn by Meindl et al. (Adv Space Res 51(7):1047–1064, 2013) are questionable. We do not agree with these conclusions and present our arguments in this article. In the first part, we review and highlight the main characteristics of the studies performed by Meindl et al. (Adv Space Res 51(7):1047–1064, 2013) to show that the experiments are quite different from those performed by Rebischung et al. (J Geod doi:10.1016/j.asr.2012.10.026,2013) . In the second part, we show that normal equation (NEQ) systems are regular when estimating geocenter coordinates, implying that the covariance matrices associated with the NEQ systems may be used to assess the sensitivity to geocenter coordinates in a standard way. The sensitivity of GNSS to the components of the geocenter is discussed. Finally, we comment on the arguments raised by Rebischung et al. (J Geod doi:10.1016/j.asr.2012.10.026, 2013) against the results of Meindl et al. (Adv Space Res 51(7):1047–1064, 2013).
