The design, manufacture and deployment of embedded systems become increasingly complex and multidisciplinary process. Before the steps of manufacturing and deployment, a simulation and validation phase is necessary. Given the increasing complexity of systems such as telecommunications systems, control systems and others, a specific simulation and validation process must take place. This simulation ideally made in a single development environment should cover different areas and all components of the system. In this paper, the authors briefly describe the behavioral models of the elements of a large scale WSN （wireless sensors network） used to create simulator, focusing specifically on the model of the transmission channel, and how it can retrieve results from the behavioral simulator. In side to legacy network simulator, for the testing and modeling of communication protocols, this simulator should not omit WSN specific aspect, in accuracy it covers the modeling of node platforms, protocols, and real world phenomena.

本文建立了一个家庭选择模型来刻画农民工家庭在城市的创业行为,并利用一项流动人口调查数据,实证检验了企业家资本对后代从农村向城市迁移后职业选择的影响。研究发现,那些具有特定家庭出身的农村移民,进城之后会有更高可能性从事企业家型的创业活动。这表明,尽管一段历史时期进行的阶级成分划分在当时给这些家庭带来了人力与物质资本方面的负面冲击,但这些家庭的非物质资本依然可以在一定程度上实现代际传递,使其后辈在迁入城市后仍更可能成为企业家型自营者,并为社会创造就业机会。未来新型城镇化模式的建立及城镇化相关政策的制定都应该更多关注自我雇佣型流动人口,尤其是激励那些企业家型流动人口的创业行为。

The design, manufacture and deployment of embedded systems become increasingly complex and multidisciplinary process. Before the steps of manufacturing and deployment, a simulation and validation phase is necessary. In this paper, a WSN （wireless sensors network） emulator, implemented on a FPGA, is described by： describing some models as examples, how multiple simulations can be done when the device was configured and programmed once, and how results from the behavioral emulator can be extracted. The diversity of applications and the typically scarce node resources set very tight constraints to WSN. It is not possible to fulfill all requirements with a general purpose WSN, for which reason the rapid development of application specific WSNs is preferred. A new emulator for the design, simulation, and evaluation of WSNs, implemented on a very dense FPGA （field programmable gate arrays）, is presented, exploring the parallelism and his resources to do a very rapid simulation ofa WSN for long periods, and without overloading memory by the intermediate data.

立体视觉不仅指对静态深度信息的感知,也包括对物体在三维空间中的运动方向的判断.本研究记录了人眼对于动态随机点图运动方向的辨别能力以及视觉训练在提高对动态信息分辨能力的作用.实验结果表明,对于没有任何相关经验的视力正常的受试者,很难分辨出动态随机点的深度运动方向,而视觉训练可以大大提高人眼对物体深度运动方向判断的敏感度.此外,这种视觉训练所达到的效果具有较长时间的持续性(至少6个月).这种通过视觉训练提高受试者对立体运动信息敏感度的方式,为立体视觉相关的实验和研究提供了新的视角.

肾脏术前计划系统首先需要实现肾脏CT造影信息的融合,实现该信息融合需要进行以肾脏为中心的腹部三维CT造影图像的配准.本文首先采用基于DDCM可形变模型的半自动分割方法从CT扫描图像中分割出肾脏轮廓线,然后对轮廓线进行重建得到肾脏的二值体数据,该二值体数据膨胀后与原CT扫描图像重建出的灰度体数据求交,即得到完全包含肾脏的灰度体数据,最后采用互信息最大化的方法对重建得到的肾脏体数据进行配准.本文分析了配准过程中初始化参数对局部极值产生的影响,并应用几何矩的性质进行参数初始化,避免陷入局部极值.实验结果表明,本文方法能够实现以肾脏为中心的术前CT造影图像的配准,并且配准的精度和速度能够满足实际应用的需要.

This study investigates climatic parameters (rainfall, and temperature) over Burkina Faso and the possible role of solar activity and its induced energies. Through morphological investigations, we analyzed solar activity indices (sunspot number, IMF, PC index, Cosmic rays) over the last three solar cycles (1975-2020). Results about interplanetary heating show that joule heating is well correlated with the dynamic pressure of the solar plasma. Climate parameters (rainfall, Temperature) variabilities are modulated by disturbances in solar activity: 1) quiet solar characterized by a drop in solar plasma’s parameters is associated with important cloud cover and consequently bring important rainfall which chills terrestrial atmosphere, 2) active solar characterized by important input energy is associated with weak incident cosmic ray consequently with low cloudiness which brings warming. Thus, the possible natural link can be suggested between solar activity and climatic parameters even if it is not the only factor of global warming.
