For Ag alloy film used for the storage media, it is required to have heat-resistance, anti-constant temperature and anti-constant humidity characteristics, corrosion resistance, while high reflectivity over Al is maintained. An Ag alloy thin film (additive element Pd, Cu, P) was created on glass substrates, and various heat treatment was conducted. then, fine structure was observed on this thin film using AFM, and fine structure evaluation of the inside was carried out by the in-plane diffractometry and X-ray diffractometry, and in addition, residual stress analysis was carried out. these results were compared and were examined, and fine structure and physical property in a metallic thin film were evaluated, and usefulness of evaluation method was verified.

Design of video encoders involves implementation of fast mode decision(FMD) algorithm to reduce computation complexity while maintaining the performance of the coding. Although H.264/scalable video coding(SVC) achieves high scalability and coding efficiency, it also has high complexity in implementing its exhaustive computation. In this paper, a novel algorithm is proposed to reduce the redundant candidate modes by making use of the correlation among layers. A desired mode list is created based on the probability to be the best mode for each block in base layer and a candidate mode selection in the enhancement layer by the correlations of modes among reference frame and current frame. Our algorithm is implemented in joint scalable video model(JSVM)9.19.15 reference software and the performance is evaluated based on the average encoding time, peak signal to noise ration(PSNR)and bit rate. the experimental results show 41.89% improvement in encoding time with minimal loss of 0.02 dB in PSNR and 0.05%increase in bit rate.

Methods of prognosis of effect of underground mining on surface deformations are nowadays well elaborated both in Czech Republic and in the world for sedimentary, especially coal deposits in which as a rule mining technology of working by long-walls is applied. However, prognosis of development of subsidence depression above ore vein deposits of slab-like type with solid adjacent rocks (deposits of Rozna type) worked by underground method is a very specific problem and it has not been satisfactorily solved until now according to available professional literature. In connection with long-term surveying observations a newly conceived mechanism of genesis of subsidence depression above uranium deposit of Rozna has been described. Based on it a geomechanical model of deposit situation is elaborated which then enables by means of mathematical modelling of surface subsidence development to predict development of subsidence depression both in stage of deposit mining and in period after termination of mining work. Further research of this problem within grant project No. 105/02/P026 of Grant Agency of Czech Republic solving proposed is oriented in connection with further real surveying observations of subsidence depression development at verifying of this newly conceived mechanism of genesis and of further development of earth surface above uranium deposit of Rozna (at further verifying of scope and degree of its validity). the research according to expectation shall contribute generally to deeper conceiving of methodology of evaluation of earth surface movements after termination of mining for ore vein deposits exploited by underground method at similar conditions.

the atomic level structures of fcc/bcc interfaces in an Fe-9Ni alloy have been examined by means of HREM. It has been found that the orientation of γ prime /α interface had great effects on its atomic structure. these interfaces with different orientations may be composed of only structural ledges, structural ledges with misfit dislocations, superledges with misfit dislocations or only misfit dislocations. A structural model of growth ledge was suggested. the terrace of growth ledge was composed of structural ledges or misfit dislocations. the atomic structure of the riser of growth ledge was the same as that of the side facet of γ prime lath, which is composed of superledges with misfit dislocations.

this vision paper discusses the advantages and disadvantages of the three main options for the recycling of rare-earth ele- ments from end-of-life fluorescent lamps：（1） direct re-use of the lamp phosphor mixture; （2） separation of the lamp phosphor mixture into the different phosphor components; （3） recovery of the rare-earth content. An overview is given of commercial activities in Europe in the domain of recycling of materials from end-of-life fluorescent lamps and the recovery of rare earths from these lamps. the collection of end-of-life fluorescent lamps is currently driven by a legal framework that prohibited the release of mercury to the environment. the contaminations of the lamp phosphor powders by mercury and by small glass particles of crushed fluorescent lamps are limiting factors in the recycling process. Research should be directed to an advanced clean-up of the reclaimed lamp phosphor fraction, and in particular to the removal of mercury and glass fragments. the recovery of rare earths from the lamp phosphors could be facilitated by taking advantage of the differences in resistance of the different lamp phosphors by chemical attack by inorganic ac- ids and bases.

the effect of heat input on martensite formation and impact properties of gas metal arc welded modified ferritic stainless steel （409M） sheets （as received） with thickness of 4 mm was described in detail in this work. the welded joints were prepared under three heat input conditions, i.e. 0.4, 0.5 and 0.6 kJ/mm using two different austenitic filler wires （308l and 316l） and shielding gas composition of Ar ＋ 5% CO2. the welded joints were evaluated by microstructure and charpy impact toughness. the dependence of weld metal microstructure on heat input and filler wires were determined by dilution calculation, Creq/Nieq ratio, stacking fault energy （SFE）, optical microscopy （OM） and transmission electron microscopy （tEM）. It was observed that the microstructure as well as impact property of weld metal was significantly affected by the heat input and filler wire. Weld metals prepared by high heat input exhibited higher amount of martensite laths and toughness compared with those prepared by medium and low heat inputs, which was true for both the filler wires. Furthermore, 308l weld metals in general provided higher amount of martensite laths and toughness than 316l weld metals.

the particle deposition behaviour of skim milk, water and maltodextrin in the conical section of a pilot-scale spray dryer was predicted using simple correlations for particle depositions in pipes. the predicted particle deposition fluxes of these materials were then compared with the measured deposition fluxes. the predicted particle deposition regimes of the spray dryer were expected to be in the diffusional and mixed (diffusional and inertial) regimes, but the experimental results suggested that the particle deposition was mainly in the inertial regime. therefore, using the pipe correlations for predicting deposition in a pilot-scale spray dryer suggests that they do not sufficiently represent the actual deposition behaviour. this outcome indicates that a further study of particle flow patterns needs to be carried out using numerical simulations (computational fluid dynamics, CFD) in view of the additional geometrical complexity of the spray dryer.
