The three pre-strained Ni 50%, Ti 50% wires with 10 mm offset from neutral axis are used. The wires are embedded along the length of rectangular beam and elastomeric core is sandwiched between two copper plates. The beam is tested for free-free boundary condition and average 48% shift in natural frequency is observed when the stiffness of beam is changed by heating the wire by 4.5 amp electric current. The effect of actuation current on damping factor and time required to regain its original frequency, after making current zero, is estimated and presented.","PeriodicalId":13708,"journal":{"name":"International Conference on Advanced Nanomaterials & Emerging Engineering Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80147499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effect of concentration of 2-Mercaptoethanol on particle size was investigated. In the absence of capping agent the yield of PbS particles was maximum. XRD shows the formation of PbS nanoparticles with cubic structure. Absorption spectra reveals the blue shift with increase in the concentration of 2-Mercaptoethanol due to decrease in particle size. EDAX study confirms the formation of stoichiometric PbS nanoaprticles for all concentration of 2-Mercaptoethanol. The average particle size of PbS nanoparticles synthesized in presence of 0.5 wt% 2-Mercaptoethanol observed from TEM image is 15 nm.

It turns out that when a zGND is attached to Ni-electrodes through S-linkers, the spin-polarized conductance exhibits oscillatory behavior with a maximum peak around θ ≈ 18°. A small change in the anisotropic spin polarization can thus cause a sudden jump in the device conductance. The two states of electronic conductance obtained by simply tuning the electrode magnetization may well serve as 1s and 0s to find potential utilities in designing spintronic logic circuits at the nanoscale.","PeriodicalId":13708,"journal":{"name":"International Conference on Advanced Nanomaterials & Emerging Engineering Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86123234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A low-complex, real trigonometric transform-based Orthogonal Frequency Division Multiplexing for Radio-over-Fiber system (RoF) is presented. The modulation/demodulation is performed by using the Fast Hartley Transform (FHT). The system is modeled and simulated using latest commercial software, Optisystem. This is an exquisite method that uses standard components of optical telecommunication. As a result this model can be used with different wireless communication systems such as high date rate Wireless LANs, Fiber-To-Home (FTTH), Wi-Max and the 4th generation cellular systems.
