Security and Privacy in RFID Applications

Concerns about privacy and security may limit the deployment of RFID technology and its benefits, therefore it is important they are identified and adequately addressed. System developers and other market actors are aware of the threats and are developing a number of counter measures. RFID systems can never be absolutely secure but effort needs to be made to ensure a proper balance between the risks and the costs of counter measures. The approach taken to privacy and security should depend on the application area and the context of a specific application. In this chapter, we selected and discussed four application areas, but there are many others where privacy and security issues are relevant.JRC.J.4-Information Societ

Cutting forces by Oak and Douglas fir machining

In this work the multi-factor, non-linear dependencies between main (tangential) F C and normal (radial) F N cutting forces upon two machining parameters by up-routing and down-routing wood of Douglas fir (Pseudotsuga Menziesii) and Oak (Quercus petraea) were evaluated. The relationships are graphically illustrated and discussed. The obtained data were compared with cutting forces evolution models according to grain orientation from the literature in order to verify if literature statements or models comply with measured data. Evidence of several contradictions was found relative to results from available literature

KINEMATICS OF MARATHON RUNNING. PART TWO: DISTRIBUTION OF VELOCITY

The paper presents description of kinematics of marathon courses’ data for men and women. The following courses were taken into account: Edmonton 2001, Boston 2002, Berlin 2002, Athens 2004. The purpose of the paper was to investigate tactics of running by mechanical data. The highest mean velocity obtained for the whole distance was 5.55 m/s for men and 5.00 m/s for women. Usually second half of a distance was run slower, but few first runners at the finish ran second half of a distance faster. Not earlier than after 30 – 35 km correlation coefficient between 5 km fragment time and the end time surpassed 0.8 value. Usually first ten runners ran with lower absolute acceleration value

Achieving efficient H2O2 production by a visible-light absorbing, highly stable photosensitized TiO2

In this paper we propose titanium dioxide modified with cobalt(II) 2-ethylhexanoate (Co@TiO2) as photoactive material for the efficient visible light driven production of H2O2. We demonstrate that visible light activity can be achieved thanks to a photoinduced electron transfer from the excited complex towards the TiO2 conduction band that corresponds to a cobalt-to-titanium-charge-transfer transition. H2O2 is synthetized by a combination of oxygen reduction and water oxidation, that is possible thanks to the correct band position of Co@TiO2. A mechanism of H2O2 formation is suggested on the basis of experimental evidences. Reactive oxygen intermediates, together with H2O2 are responsible for the photocatalytic degradation of a nonionic surfactant, methylene blue and phenol for wastewater treatments. Finally, and quite interestingly, Co@TiO2 can be also used in a photoelectrochemical setup, where it can be adopted both as photoanode and photocatode, and the switching potential corresponds to the redox potential of the adsorbed complex Co(III)/Co(II) couple
