We investigate the effect of word typicality — the degree of membership of a word to its superordinate category — on the N400 event-related potential (ERP) using a single trial detection approach based on spatiotemporal beamforming. Unlike the norm in studies, where mostly concrete categories are used (imaginable objects), we considered a total of 6 basic categories: three abstract and unimaginable...
There is just 4.8m between the provincial road and the Grand Canal, if the conventional bridge type is adopted, it will increase the engineering's investment greatly. The paper gives a applicable design method and put forward an asymmetric bridge structure. It decreases the engineering's investment greatly. This paper introduces the method's key points, analyses the upper structure and lower structure...
In this paper a new approach allowing measurements of dielectric permittivity on crystalline samples in the frequency range of 50–75GHz using Vector Network Analyzer is introduced. An approbation of the setup was performed on the sample of optical glass in the selected frequency range. Experimental results for optical glass were also obtained using time domain processing technique with the proposed...
This research proposes a framework that aggregates resources for formal investigation of different properties of systems using disparate analysis methodologies such as simulation, formal methods and code synthesis for real time enactment. There is a plethora of development environments that support individual analysis methodologies; however, those that truly support multiple methods are not common...
We are currently interested in the study of core concepts: playfulness, imagination, creativity. In here we are looking at existing theoretical perspectives on these concepts, trying to understand the relationships between them, to identify unanswered questions. While trying to put into evidence the relationships between these concepts for the study of creative processes, we aim at designing future...
This paper proposes the usage of a learning activity based recommendation approach for fostering self-regulated learning in a personal learning environment. For this purpose two widgets are developed and evaluated, which allow learners to compile an individual learning plan from recommendations of learning activities that match a given task.
Generally, Performance Assessment (PA) of Construction Subject (CS) is based on “Post-Evaluation”. For one-time construction process, PA has limited ability to evaluate the process objectively. The Basic Model of the evaluation upon Process Performance (PP) in Construction Project (CP) was setup in this paper by AHP based on the Fuzzy Evaluation Method, and also by the study of comparison between...
In this paper an investigation on TGRM cementitious special grouting materials performance of setting time, fluidity, expansion ratio, elastic modulus, strength of compression and bending with different water-cement ratio is presented. Experimental results show that the material has the performance of rapid setting, high fluidity, low elasticitymodulus, higher strength of compression and tensile,...
Analysis on size effect of calculation theory for ultimate bearing capacity of flexural member is carried out in this paper, including basic assumptions and calculation equations. The paper collects test information of five different section size samples in the state of ultimate bearing capacity, including sectional bending moment, deflection and section strain etc. The total number of RC free beam...
The energy saving wall with wire-mesh frame being designed is poured with EPS light-weight concrete and wire mesh frame. The thermal analysis has been done, and the thick of the wall has been determined. The appropriate mixture ratio of EPS concrete and the construction method have been obtained through experiment. The construction of the wire mesh frame has been designed by using finite element software...
Many researches on size effect of quasi-brittle materials have been carried out. But experiment combining with RC structures is not sufficient. At present, design values in rules and regulations are mainly based on experimental results of small size test samples, which exist different from practical engineering structures. Meeting structural normal using function is a basic principle of structural...
It is very important to choose reasonable test data for testing and verifying the correctness of a program, and this paper discusses and analyzes the methods of how to design the program test data in detail. It deems that the method of equivalent type division can be used for choosing the test data of a program when there is a clear-cut input data area, and the method of boundary value analysis can...
As the acquaintance with the safety of structure is improved, the structure health monitoring play a more important role, in which damage identification is a key problem. In this paper, for reinforced concrete beams, β index and η index based on flexibility matrix are proposed to detect damage. Two RC beams with a span of 7m are tested and the proposed indexes are used to identify damages.
Typically, to meet the higher requirements of stiffness and integrity, a rigid connection is mostly used between the structural elements of high-rise building structures. However, in some special cases, it is more appropriate that hinged connection handle is used in some special parts of the structures. Several special circumstances about the application of hinged connection handle in structures of...
Take modern teaching theories as foundation, author carry on summary and research to parts of results of education reform in recent years, which is based on the principle of the analytical class teaching design and the foundation of the main contents with combining fulfillment experience that is engaged in professional foundation lesson teaching for several years.
Experimental studies on the shear capacity of the adhesion by the water-soluble polyurethane and concrete slot, which gets the relationship between vertical stress and shear stress. According to the sample, analyzed the patterns of damage and provided a reference for the actual and theoretical foundation, and solved the main Faced Rock-fill Dam of the slot (Peripheral joint, Expansion joint).
Based on the set pair analysis (SPA) and the variable fuzzy sets theory, In order to simplify the evaluation procedure of relative difference degree and make the accurate evaluation of the the integrity of pile foundation quantitatively, a new variable fuzzy set model for evaluation of integrity of pile foundation was established. Moreover, it was shown by comparison of results between a practical...
The north anchorage of Taizhou Changjiang River highway bridge is made by a large open caisson, length of the caisson is 67.9m, the width is 52.0m, and the height is 57m. The caisson divided into 11 segments in total, the first segment is 8m long, made by steel covered concrete, the 10th segment is 4m long, and the other are 5m, all made by reinforced concrete. By Surveying, Choosing by the fact that...
There are a great number of concrete structures existing in the atmospheric environment. The process of industrialization has led to the severe air pollution. The acid rain areas expand so severely that the neutralization of concrete is increasingly concerned about. Acid rain is the most ordinary acidic material in the atmospheric environment. In this paper, the neutralization process of acid rain...
