In this work, an on-chip V-band 4×1 linear tapered slot antenna (LTSA) array is proposed, which is realized using a glass-based integrated passive device process. To ease the integration with the transceiver, coplanar waveguide (CPW) is chosen for the antenna input port design and a compact lumped-element CPW-to-slotline transition is employed to realize the feeding structure of the LTSA. In this...
In recent years, as network information technology has increasingly advanced, there is a growing trend of people using electronic devices. With the rise of social network services (SNSs), people are using SNSs more frequently, SNSs have gradually replaced many traditional methods of contacting, such as sending e-mails, typing text messages, or chatting on the phone. However, current commercially-available...
This paper starting from the teacher assessment data, analyze whether the evaluation indicators are suitable for factor analysis, then find the two factors which played a decisive role in evaluation indicators these indicators were interactive and related, so as to achieve the purpose of simplifying calculation. Final get the teachers' rankings by factor analysis.
Thermal insulation glazed hollow bead and ceramisite concrete aimed at building energy conservation of the development of the research of the structure of self- thermal insulation material. The performance optimization research on mechanical properties and thermal properties is the key problem in developing process. The objectives of performance optimization were proposed firstly. Based on the performance...
Under the network environment, security of library information system(LISS) is an important topic for all managers. This paper analyzes main categories of security of library information system and puts forward efficient means of protecting this system. The paper finally points out the significance of security of library information system.
The conception of grid-based Books resource sharing is proposed as well as the six-layer sharing platform architecture. The construction of the grid-based books resource sharing platform is discussed. Finally, the management process of grid-based books resource sharing platform is illustrated.
This paper mainly analyses the current situation of building the digital library, explains the theory of knowledge management in the digital library, and probes into the strategies of the digital library that applying knowledge management. Following four aspects are the key contents in the paper. At last, the application of knowledge management techniques can be concluded in the digital library.
Investment income of Innovation projects is uncertainty, the objective existence of uncertainty determines the innovation project investment has certain risk, in this high-risk investment environment to achieve the expected benefits it is necessary to conduct risk analysis of investment projects. Construction of a set of science and innovation investment risk evaluation index system, the application...
Majority of teaching quality evaluation uses fuzzy comprehensive evaluation at present. The fuzzy comprehensive evaluation is good at dealing with the subjective evaluation information. But it is not good at dealing with the objective evaluation information. To solve the problem, the paper used two mathematical models which were fuzzy comprehensive evaluation and Markov chain to handle the information...
Data quality is quite significant for management information systems in all fields. However, various data quality problems, from spelling mistakes to complex inconsistencies in semantics, penetrate all over into the systems. The purpose of data cleaning is to detect and eliminate the dirty data and improve the data quality. The data quality problems and the current research results of data cleaning...
This paper proposes a model for recovering writing sequence from offline handwritten Chinese character image. In this model, a 4-layer hierarchy is presented to model Chinese character, where characters, components, subcomponents and strokes are located at each layer, respectively. Characters are decomposed to components and components are decomposed to subcomponents in turn by four decomposing operators...
