Many current applications for co-generation centre on methane-fuelled systems with steam internal reforming to break the methane down into hydrogen and carbon dioxide As dependency on hydrocarbon fuels diminishes, a role for the fuel cell that is more inkeeping with the renewable scheme of Fig, 625 is more likely to prevail Ageneral method for modelling stacked fuel cells can be found in Lee & Lalk (1998) The most promising options for building co-generation systems, at least in the short-to-medium term, are (classi ed by electrolyte) the solid oxide (SOFC) and molten carbonate (MCFC) fuel cells These types operate at temperatures of 1000 C and 650oC respectively making them suitable for high grade heat recovery as well as the potential for steam raising for internal reforming if needed Simple owsheet modelling approaches for a SOFC can be found in Riensche et al.

3 The extraordinary growth of social networks on the Web suggests that many people recognize a human need for such connections and are trying to find them as best they can The technology industry, especially the software industry, which is only about 30 years old, started user groups early on A company like Lotus or Microsoft or Oracle would pay to bring its software users together to enjoy speakers and educational content, refreshments, and entertainment as a way to.

(1998) and, for the MCFC, in Au et al (2003) Interest in wind turbine applications on buildings is based on the idea of accelerating or concentrating the dominant wind site-trajectory onto a wind turbine Horizontal axis wind turbines (HAWT) are of greatest practical interest due to the limited commercial availability of vertical axis turbines Campbell & Stankovic (1999) present prototype designs for a variety of concentrator possibilities based on a number of built forms such as twin towers and building in ll sections Modelling of wind turbines has been well documented in the literature (eg Nathan 1980; Welfonder et al 1997; Maalawi & Badawy 2001), the simple curve- t based model of Welfoner et al.

being particularly appealing for integration within building energy models: Pturbine = in which: Pturbine = turbine power extracted from wind (W) r = air density at turbine site (kg m-3) CP = power coef cient A = rotor swept area (m2) uw = axis-corrected wind speed (m s-1) The power coef cient, CP, can be tted from test data (Welfonder et al 1997) Most photovoltaic (PV) modelling applications for building energy problems can quite adequately be represented at module detail rather than at cell detail where a very good correlation between in-plane irradiance and power yield can be expected over the uniformly insolated surface However, it is desirable to model the problem with the inclusion of module temperature since this will vary according to the instantaneous module heat balance as well as across the seasons.

From Program 9.1, it can be seen that a call to get n golf balls willblock a calling thread until enough balls become available.M e n a thread returns golf balls, all blocked threads are awakened so that they can see if there are now sufficient for them to proceed. Notice that this allows a thread trying to get a large number of golf balls to remain blocked while a thread requiring fewer can proceed. The P l a y e r A r r i v a l class creates new P l a y e r threads in response to button presses.Eachnewly-created thread is passed a reference to the applet class Golf Club. The thread needs this reference since it calls the golf ball allocator monitor indirectlythe via GolfClub methods g e t G o l f B a l l s () and r e 1GoI f Balls(). The program has been organized this way to avoid passing all the display objects to every newly-created thread. The code for the P l a y e r class is listed in. Program 9.2.

A common characteristic of fold and thrust belts is the presence of one or more d collement (or detachment) surfaces that underlie shortened sequences of sedimentary and volcanic rock (Section 97) The geometry of these surfaces tends to conform to the shape of the sedimentary and volcanic sections in which they form In most foreland basins sedimentary sequences thin toward the foreland, resulting in d collements that dip toward the hinterland (Figs 105b, 107) In thin-skinned thrust belts (Section 1024, Fig 105b), the lowermost, or basal, d collement separates a laterally displaced sedimentary cover from an underlying basement that is still in its original position In thick-skinned styles (Fig 105d), the d collement surface cuts down through and involves the crystalline basement.
