摘要：analysis of functional MRI (fMRI) blood oxygenation level dependent (BOLD) data is typically carried out in the time domain where the data has a high temporal correlation. These analyses usually employ parametric models of the hemodynamic response function (HRF) where either pre-whitening of the data is attempted or autoregressive (AR) models are employed to model the noise. Statistical analysis then proceeds via regression of the convolution of the HRF with the input stimuli. This approach has limitations when considering that the time series collected are embedded in a brain image in which the AR model order may vary and pre-whitening techniques may be insufficient for handling faster sampling times. However fMRI data can be analyzed in the Fourier domain where the assumptions made as to the structure of the noise can be less restrictive and hypothesis tests are straightforward for single subject analysis, especially useful in a clinical setting. This allows for experiments that can have both fast temporal sampling and event-related designs where stimuli can be closely spaced in time. Equally important, statistical analysis in the Fourier domain focuses on hypothesis tests based on nonparametric estimates of the hemodynamic transfer function (HRF in the frequency domain). This is especially important for experimental designs involving multiple states (drug or stimulus induced) that may alter the form of the response function. In this context a univariate general linear model in the Fourier domain has been applied to analyze BOLD data sampled at a rate of 400 ms from an experiment that used a two-way ANOVA design for the deterministic stimulus inputs with inter-stimulus time intervals chosen from Poisson distributions of equal intensity.

摘要：The paper had introduced the development stage and role of site analysis in landscape design. By taking Canal Park in Yichang City for example, landscape design concepts had been discussed and design concepts of this park had been summarized as: continuing history and culture of the site; forming rare urban wetland landscape; respecting surrounding environment and integrating leisure recreation with ideal landscape layout; displaying regional customs through core scenic spots; manifesting regional features through plants' planning. After the analysis of features of Canal Park, four approaches for urban park features construction had been revealed, that is, guiding with new concept by centering on urban development requirement; reflecting regional customs; exploiting local historical resources; and fully expressing the property of the park. It was considered that urban park feature construction should be based on site analysis. Through exploitation and refinement of overt natural landscape features and covert cultural and historical resources, they should be decomposed, processed and integrated into concrete concepts. Finally, individual features of the site even the city could be embodied in concrete landscape factors.

摘要：This paper presents the use of solar energy for generation of electrical energy through solar pho-tovoltaic (SPV) system to meet the load requirement of a domestic building. Complete design and economic analysis of SPV system for different costs of SPV module is done and compared with grid electricity for with and without storage conditions. The results of the study encourage the use of SPV system for a residential building and show that SPV system is an economically viable option to meet the exponentially growing electricity requirement for household applications in India.

摘要：Based on the concept of site characteristic and site spirit,by taking the Residential Community of the Fifth Agricultural Construction Division in Bole City of Xinjiang Uygur Autonomous Region for example,the paper has analyzed its background and general situation,and the site characteristic,and emphasized that its planning and design should manifest the comfortable and cozy environment of the residential community,army culture unique in the Fifth Agricultural Division of Xinjiang Crops,and its enterprising *** has pointed out the design should highlight people orientation;stress the quality of living environment;emphasize the individuality of the residential community;combine new technologies;respect the sunshine,terrain and waterscape of the site;well deal with the spatial location of the site;and pay attention to the inheritance of historical culture in the site,so as to create a high-grade residential community integrating army crops feature and water style,with complete supporting facilities,and in possession of unique sharing space,broad landscape avenue and wide building span.

摘要：In semiconductor manufacturing process, probe station that is testing equipment is important. Inspection step is for detecting defects on semiconductor before the packaging. Probe card is a part of probe station and contains probe tip that contacts to semiconductor. Through probe tip, it can inspect defects of semiconductor. In this paper, optimization method is used with response surface analysis to design MEMS type probe tip. And fabricating probe tip uses maskless lithography, electro-plating and lapping process.

摘要：A common current source, generally used to bias cross-coupled differential amplifiers in a transconductor, controls third harmonic distortion (HD3) poorly. Separate current sources are shown to provide better control on HD3) . In this paper, a detailed design and analysis is presented for a transconductor made using this biasing technique. The transconductor, in addition, is made to offer high Gm, low power dissipation and is designed for linearly tunable Gm with current mode load as one of the applications. The circuit exhibits HD3) of less than –43.7 dB, high current efficiency of 1.18 V-1 and Gm of 390 μS at 1 VGp-p @ 50 MHz. UMC 0.18 μm CMOS process technology is used for simulation at supply voltage of 1.8 V.

摘要：This paper presents a method for designing a class of countermeasures for DPA attacks based on attenuation of current variations. In this class of countermeasures, designers aim at decreasing the dynamic current variations to reduce the information that can be extracted from the current consumption of secure microsystems. The proposed method is based on a novel formula that calculates the number of current traces required for a successful DPA attack using the characteristics of the microsystem current signal and the external noise of the measurement setup. The different stages of the proposed method are illustrated through designing an example current flattening circuit. Meanwhile validity and applicability of the proposed formula is verified by comparing theoretical results with those obtained experimentally for the example circuit. The proposed formula not only estimates the required level of attenuation for a target level of robustness defined by design requirements, it also predicts the effectiveness of a countermeasure using simulation results therefore dramatically reducing the time to design of secure microsystems.

摘要：On the basis of a detailed introduction to the concept of language learners’needs, this paper illustrates the importance of needs analysis, both pre course analysis and ongoing analysis, in curriculum designing. By doing so, teachers can not only collect factual information for the purpose of setting broad goals related to language content; but also gather information about learners which can be used to guide the learning process once it’s under way. Learners, on the other hand, can be aware of their own learning under the direction of the specified objectives.
