An Overview of Smart Card Security. The smart card, an intelligent token, is a credit card sized plastic card embedded with an integrated circuit chip. It provides not only memory capacity, but computational capability as well. The self-containment of smart card makes it resistant to attack as it does not need to depend upon potentially vulnerable external resources. Because of this characteristic, smart cards are often used in different applications which require strong security protection and authentication.

A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication systems. This program is valuable for future researchers simulating systems that are too theoretically complex to analyze. Single-carrier QAM and multicarrier OFDM are compared to demonstrate the strength of OFDM in multipath channels. Two graphical user interface demonstrations show some of the basic concepts of OFDM.

The object detector described below has been initially proposed by P.F. Felzenszwalb in [Felzenszwalb2010]. It is based on a Dalal-Triggs detector that uses a single filter on histogram of oriented gradients (HOG) features to represent an object category. This detector uses a sliding window approach, where a filter is applied at all positions and scales of an image. The first innovation is enriching the Dalal-Triggs model using a star-structured part-based model defined by a “root” filter (analogous to the Dalal-Triggs filter) plus a set of parts filters and associated deformation models. The score of one of star models at a particular position and scale within an image is the score of the root filter at the given location plus the sum over parts of the maximum, over placements of that part, of the part filter score on its location minus a deformation cost easuring the deviation of the part from its ideal location relative to the root. Both root and part filter scores are defined by the dot product between a filter (a set of weights) and a subwindow of a feature pyramid computed from the input image. Another improvement is a representation of the class of models by a mixture of star models. The score of a mixture model at a particular position and scale is the maximum over components, of the score of that component model at the given location.

PixelFusion.dsp This file (the project file) contains information at the project level and is used to build a single project or subproject. Other users can share the project (.dsp) file, but they should export the makefiles locally. PixelFusion.h This is the main header file for the application. It includes other project specific headers (including Resource.h) and declares the CPixelFusionApp application class. PixelFusion.cpp This is the main application source file that contains the application class CPixelFusionApp. PixelFusion.rc This is a listing of all of the Microsoft Windows resources that the program uses. It includes the icons, bitmaps, and cursors that are stored in the RES subdirectory. This file can be directly edited in Microsoft Visual C++. PixelFusion.clw This file contains information used by ClassWizard to edit existing classes or add new classes. ClassWizard also uses this file to store information needed to create and edit message maps and dialog data maps and to create prototype member functions.

一种以硅单晶为基本材料的P1N1P2N2四层三端器件，创制于1957年，由于它特性类似 双向可控硅 于真空闸流管，所以国际上通称为硅晶体闸流管，简称可控硅T。又由于可控硅最初应用于可控整流方面所以又称为硅可控整流元件，简称为可控硅SCR。 在性能上，可控硅不仅具有单向导电性，而且还具有比硅整流元件（俗称“死硅 ”）更为可贵的可控性。它只有导通和关断两种状态。 可控硅能以毫安级电流控制大功率的机电设备，如果超过此频率，因元件开关损耗显著增加，允许通过的平均电流相降低，此时，标称电流应降级使用。 可控硅的优点很多，例如：以小功率控制大功率，功率放大倍数高达几十万倍；反应极快，在微秒级内开通、关断；无触点运行，无火花、无噪音；效率高，成本低等等。 可控硅的弱点：静态及动态的过载能力较差；容易受干扰而误导通。
