Anti-Freezing Mechanism Analysis of a Finned Flat Tube in an Air-Cooled Condenser
Energies, 2017 In cold winter weather, the air-cooled condensers (ACCs) face serious freezing risks, especially with part load of the power generating unit. Therefore, it is of benefit to investigate the heat transfer process between the turbine exhaust steam and ...

Glasgow Mathematical Journal, 2017 AbstractThis paper is about the connection between certain Banach-algebraic properties of a commutative Banach algebra E with unit and the associated commutative Banach algebra C(X, E) of all continuous functions from a compact Hausdorff space X into E. The properties concern Ditkin's condition and bounded relative units.

Toughening of silicon nitride ceramics through stress-induced phase transformation
Journal of Advanced CeramicsCeramics, particularly covalently bonded ceramics, exhibit intrinsic brittleness resulting from the strong directional nature of their chemical bonds, significantly limiting their applications.

Journal of Computer and System Sciences, 1977 A new type of grammar for generating formal languages, called a conditional grammar is presented. A conditional grammar generates the language in a deterministic way and its operation resembles that of a program. Classes of languages generated by some subclasses of conditional grammars are investigated and related to known classes of languages.

Investigating the Dehumidification Characteristics of Turbine Stator Cascades with Parallel Channels
Energies, 2018 Steam turbines play a vital role in the power industry. The efficiency of the steam turbine can be improved by reforming the flow structure. For the White cascade, a parallel channel which is an additional steam passage was designed to connect adjacent ...

Conditions on conditional mood [PDF]
Acta Linguistica Hungarica, 2006 This paper argues that conditional mood morphology in Hungarian is the spellout of a morphosyntactic feature excl(w), the semantic interpretation of which is modal exclusion, i.e., counterfactuality. In certain cases (such as wishes, or CF conditionals) this feature is lexically specified on M[ood], with the direct interpretive aim of counterfactuality,
