Although computing the transient response of fractional oscillators, characterized by second-order differential equations with derivatives for damping term, to external loadings has been studied, most existing methodologies have dealt cases either restricted orders or simple loadings. In this paper, considering complicated irregular, but deterministic, acting on oscillators any order between 0 ...

Near Field Communication (NFC) is a Radio Frequency (RF) technology that allows data to be exchanged between devices that are in close proximity. An NFC-based mobile coupon (M-coupon) is a coupon that is retrieved by the user from a source such as a newspaper or a smart poster and redeemed afterwards. The M-coupon is a cryptographically secured electronic message with some value stored on user’...

We study the information rates of unipolar orthogonal frequency division multiplexing (OFDM) in discrete-time optical intensity channels (OIC) with Gaussian noise under average optical power constraint. Several single-, double-, and multicomponent unipolar OFDM schemes are considered under the assumption that independent and identically distributed (i.i.d.) Gaussian or complex Gaussian codebook...

Electronic circuit simulation, especially for radio frequency RF and microwave telecommunications, is being challenged by increasingly complex applications presenting signals of very different nature and evolving on widely separated time scales. In this paper, we will briefly review some recently developed ways to address these challenges, by describing some advanced numerical simulation techni...

In this paper, a novel second-order transmission condition is developed in the framework of non-conformal finite element domain decomposition method to meet the challenges brought by complex and large-scale electromagnetic modeling. First, it is implemented efficiently on the non-conformal interface via a Gauss integral scheme. Then, the eigenvalue analysis of the DDM system show a more cluster...

Recently, the authors introduced an algebraic design framework for space–time coding in flat-fading channels [1]–[4]. In this correspondence, we extend this framework to design algebraic codes for multiple-input multiple-output (MIMO) frequency-selective fading channels. The proposed codes strive to optimally exploit both the spatial and frequency diversity available in the channel. We consider...

Product information given in purchase situations influences purchase behavior. In online purchase situations, the use of recommendation agents increases the value of product information as information becomes adaptive and thus more relevant to consumers’ information needs. Correspondingly, mobile recommendation agents (MRAs) may also increase the value of product information in bricks-and-morta...

A novel algorithm for solving the LPN problem is proposed and analyzed. The algorithm originates from the recently proposed advanced fast correlation attacks, and it employs the concepts of decimation, linear combining, hypothesizing and minimum distance decoding. The proposed algorithm appears as more powerful than the best one previously reported known as the BKW algorithm. In fact the BKW al...

Job-Hopping in Silicon Valley: Some Evidence Concerning the Micro-Foundations of a High Technology Cluster In Silicon Valley’s computer cluster, skilled employees are reported to move rapidly between competing firms. This job-hopping facilitates the reallocation of resources towards firms with superior innovations, but it also creates human capital externalities that reduce incentives to invest...
