Two new preliminary component types were developed for the transient simulation program TRNSYS with IISiBat that models three different types of sensible thermal storages for analysis with use in a solar electric generating system (SEGS) simulation. One component containing a fully mixed, a stratified and a plug flow tank model options has been developed such that the input and parameter specifications are similar so that all three models could be easily placed into one component type. A single, cylindrical direct storage tank with one inlet and one outlet that evaluates fluid properties as a function of temperature is representative for all three models. The second component is a storage controller that passes along pertinent charging, dwell or discharging information to the storage and integrates the storage into a given SEGS model. Results were generated for each storage tank integrated into a SEGS VI simulation model for temperature distribution and power generation.

With the gradual maturity of component oriented software development method, component-based software evolution technology has become hot research in academia and industry. Although many evolution rules are designed, they rarely consider component type-mismatched problem in evolution rules. This has led to evolution rules that often run error in software evolution execution. Hence, focusing on the mismatch problem of component type in software evolution, this paper addresses various evolution rules with condition constrains to support component type matching. First, we use the bigraph theory to model the software architecture and employ bigraph term language to describe the basic component evolution operations. Second, we join type system into the term language and use the type term language to express the condition constraints on position and connection for component evolution rules. These condition constraints can guarantee the type-matched among components that participate in software evolution. Furthermore, we show that the component type-matched still kept during a number of different evolution rules are used in the whole software evolution reaction system. Finally, two cases study of evolution progress of ATM system and tourism information system are presented. Two cases illustrate the effectiveness of our approach.

Abstract. Multi-rotor wind turbines (MRWTs) have been suggested in the literature as a solution to achieving wind turbine systems with capacities greater than 10 MW. MRWTs utilize a large number of small rotors connected to one support structure instead of one large rotor with the aim of circumventing the square cube law. Potential benefits of MRWTs include cost and material savings, standardization of parts, increased control possibilities, and improved logistics for assembly and maintenance. Almost all previous work has focused on mechanical and aerodynamic feasibility, with almost no attention being paid to the electrical systems. In this research eight different topologies of the electrical collection network for MRWTs are analysed to assess which are the most economically and practically viable options. AC and DC collection networks are presented in radial, star, cluster and DC series topologies. Mass, capital cost and losses are estimated based on scaling relationships from the academic literature and up-to-date commercial data. The focus of this study is the assessment of the type of electrical collector topology, so component type and voltage level are kept consistent between topology designs in order to facilitate a fair comparison. Topologies are compared in terms of four main criteria: capital cost, cost effectiveness, total mass and reliability. A comparison table is presented to summarize the findings of the research in a convenient way. It is found that the most cost-effective solutions are the AC radial and AC star topologies, with the least cost-effective being the DC series–parallel and DC cluster topologies. This is due to the high cost of DC–DC converters and DC switchgear along with the lower efficiency of DC converters. Radial designs perform best in terms of efficiency and annual energy capture. DC systems achieve a slightly lower nacelle mass compared to their equivalent AC systems. DC topologies are generally found to be more expensive when compared to their AC counterparts due to the high cost of DC–DC converters and DC switchgear. Star topologies are considered to have the best reliability due to having no shared equipment. The most suitable collection topology for MRWTs is shown to be of the star type, in which each turbine is connected to the step-up transformer via its own cable.

Doped SrTiO3 becomes a metal at extremely low doping concentrations n and is even superconducting at n < 1020 cm−3, with the superconducting transition temperature adopting a dome-like shape with increasing carrier concentration. In this paper it is shown within the polarizability model and from first principles calculations that up to a well-defined carrier concentration nc transverse optic mode softening takes place together with polar nano-domain formation, which provides evidence of inhomogeneity and a two-component type behavior with metallicity coexisting with polarity. Beyond this region, a conventional metal is formed where superconductivity as well as mode softening is absent. For n ≤ nc the effective electron-phonon coupling follows the superconducting transition temperature. Effusion measurements, as well as macroscopic and nanoscopic conductivity measurements, indicate that the distribution of oxygen vacancies is local and inhomogeneous, from which it is concluded that metallicity stems from filaments which are embedded in a polar matrix as long as n ≤ nc.

Building-information-modeling for cultural heritage (HBIM), which is established using surveying data, can be used to conserve architectural heritage. The development of an HBIM model for ancient wooden architecture (AWA) structures requires interdisciplinary integration. A parametric model for the main components that intelligently integrates the historical knowledge, as well as an intelligent modeling method for these components, are two critical issues required to bridge the existing gap and improve the application of HBIM. Taking an AWA structure constructed during the Liao and Song Dynasties as an example, the parametric model for the typical components, with emphasis on commonality and characteristics, were first proposed. Subsequently, an intelligent automated modeling method was developed and programmed using Dynamo, which can intelligently identify the component type and determine the invisible dimensions. A complicated dou-gong was successfully established with surveying data using the proposed method within five minutes, thereby validating the reliability and efficiency of this method. Furthermore, the proposed method was used to establish the HBIM model of Yingxian Wood Pagoda, which is the oldest and tallest AWA structure in China with a height of 65.88 m. The research findings will provide an essential reference for the conservation of wooden architectural heritage structures.

Blood Factors

Abstract The complex serologic behavior of the Rh-Hr agglutinogens has been underlined by the recent discovery that, with very rare exceptions, associated with blood factor Rho of Rh-positive blood, there are numerous other blood factors which may be designated RhA, RhB, RhC, etc. Rare Rh-positive individuals exist whose bloods have blood factor Rho but lack one or more of the other components. Such individuals can and have become sensitized to the missing blood factor. For example, in the case of an Rh-positive individual lacking blood factor RhA, anti-RhA may be produced. When RhB and/or RhC are lacking, anti-RhB and anti-RhC may be produced. In fact, we have identified all three antibodies. These three antiserums are indistinguishable from "standard" anti-Rho serum in parallel tests on a random series of blood specimens unless one of the rare Rh-positive bloods lacking blood factor RhA, RhB or RhC are included. In the present paper, anti-RhA serum from a sensitized type $$Word$$ mother whose child had erythroblastosis was used for studies on the distribution and heredity of the RhA blood factor. A total of 2012 blood specimens from Rho-positive individuals were tested; 951 from Caucasoids and 918 from Negroids. In tests on blood from Caucasoids, a "standard" Rho blood factor was invariably associated with a "standard" RhA blood factcr. In no instance where the reactions with anti-Rho serums were typical was the RhA factor absent or a variant. However, if the Rho factor was a variant, three possibilities with regard to factor RhA were identified. Either factor RhA was "standard," or factor RhA was a variant, or factor RhA was absent. This last possibility rarely occurs in Caucasoids since in our series only one Caucasoid blood or 0.1 per cent lacked RhA blood factor and in that case the Rho factor was a variant. Among the 918 Rh-positive blood specimens from Negroids examined the situation was found to be somewhat different. While a "standard" Rho blood factor was almost always associated with a "standard" RhA blood factor, in 0.9 per cent the RhA factor was absent. Among blood specimens with a Rho variant blood factor, just as with Caucasoids, all three possibilities were identified, namely, bloods with "standard" RhA blood factor, with RhA variant blood factor and also bloods with blood factor RhA absent. The incidence of Rh-positive bloods lacking factor RhA was considerably higher among Negroids than among Caucasoids, namely, 1.6 per cent in Negroids, as compared with only 0.1 per cent in Caucasoids. One interesting family was studied. The father’s blood had the "standard" Rho blood factor, but lacked the RhA component (type $$Word$$). The mother’s blood had the Rho variant blood factor, and also lacked blood factor RhA (type $$Word$$). The child’s blood was of the same type as its mother, namely, Rho variant and lacking blood factor RhA (type $$Word$$). Possible genetic explanations for these observations and their clinical significance are discussed.
