We have performed Raman spectroscopy using a near-field scanning optical microscope. The small sample volume coupled with the light-starved nature of the Raman effect makes nano-Raman studies difficult. We present results showing near-field effects in an investigation of Rb-doped KTP. These effects include a change in selection rules due to the presence of a z-polarization component in the near...

Ranging from booking to check-in to baggage drop to boarding to border crossing to baggage recovery, the trend is irrevocable and subject to significant growth. This growth goes both for increased use of mature self-service options, such as for check-in, but also for new services such as self-service bagdrop. Emerging technologies, like Near Field Communication (NFC), is also likely to play a r...

This paper explores NFC based applications adequate for the use in retail stores and analyses the influence that these could have on the prevailing customer shopping process. It emphasizes the fact that NFC could provide shoppers with more benefits beyond faster payments. On the one hand, NFC based rebate coupons and loyalty cards could further accelerate the check-out process. On the other han...

In this paper we present the advantages and possibilities of a modular test platform for the evaluation of security protocols in NFC applications. Furthermore, we also depict some practical implementation results of this modular system. The scope of the platform is to provide a highly modular system. Adding or removing certain functionality can be done without the need of rebuilding the entire ...

Characteristics of ground motions close to the earthquake source can be considerably different from those of far-field motions which should be considered in design process of structures. The current study aimed to present new design response spectra for Iranian seismic design code taking into account the near-fault effects. For this purpose, a new attenuation relation based on the ground motion...

simultaneous estimation of the range and the angle of close emitters usually requires a multidimensional search. this paper proposes analgorithm to improve the position of an element for arrays designed on the basis of some certain or random rules. in the proposed method,one element moves along the same previous direction, maintaining its vertical distance from each source, to reach a constella...

abstract following the advances in mobile communication and information technology, smart phones have been used in a wide variety of commercial, social, entertainment, file sharing and health transactions and applications. the current procedures in healthcare environment for patient registration, appointment scheduling and payment are time consuming and somehow tiresome. traditionally, patients...

Typically, to study the effects of consecutive earthquakes, it is necessary to consider definite intensity levels of the first shock. Methods commonly used to define intensity involve scaling the first shock to a specified maximum interstorey drift. In this study the structure’s predefined elastic spectral acceleration caused by the first shock is also considered for scaling. This study aims to...
