  • Why Is the Focus on Innovation and New Technologies As the Solution to the Jobs Crisis?

    While creating new industries and innovative technologies may be a long-term solution to systemic unemployment, they will take years to move from concept to development and finally deployment. The existing U.S. workforce is not prepared to undertake radical changes in the life skills needed to succeed in these new high-tech industries. The job mix in our current economy is weighted to the service sector by more than 80%. Within the call center sector alone, we have lost more than 7 million jobs to India and the Philippines and other low-cost markets. While these jobs are not the highest paying and are certainly not glamorous, they are jobs that are easily learned and can absorb large numbers of workers right now. Why can?t we act to protect these jobs and reverse the migration of call center work back to the United States? View full abstract»

    The goal for the biennial American Solar Challenge (ASC) is for participating universities to build and race solar-powered electric vehicles across the country on public roads. While the route maps have varied greatly since the competition began as the GM Sunrayce in 1990, the distance traveled is typically between 1,200 and 2,400 mi. In 2012, the 1,650-mi race route from Rochester, New York, to St. Paul, Minnesota, took solar car teams through all of the states bordering the Great Lakes, using the slogan ?Eight States in Eight Days.?

  • Wave Field Synthesis: The Future of Spatial Audio

    We all are used to perceiving sound in a three-dimensional (3-D) world. In order to reproduce real-world sound in an enclosed room or theater, extensive study on how spatial sound can be created has been an active research topic for decades. Spatial audio is an illusion of creating sound objects that can be spatially positioned in a 3-D space by passing original sound tracks through a sound-rendering system and reproduced through multiple transducers, which are distributed around the listening space. The reproduced sound field aims to achieve a perception of spaciousness and sense of directivity of the sound objects. Ideally, such a sound reproduction system should give listeners a sense of an immersive 3-D sound experience. Spatial audio can primarily be divided into three types of sound reproduction techniques, namely, loudspeaker stereophony, binaural technology, and reconstruction using synthesis of the natural wave field [which includes Ambisonics and wave field synthesis (WFS)], as shown in Fig. 1(a).

  • The Vectorial Nature of Electric Current: Modification of Maxwell?s Equation of the Electromagnetic Field

    The theoretical study of physical science and engineering is based on many conventions that have already earned international recognition. But what is it about those conventions that have no resemblance with real-life situations? There is an urgent need to consider and remove such conventions, either with alternative replacements in compliance with real-life situations or deal with a problem where such a convention is used by alternative treatment so as to establish a bridge between theory and practice. Such attempts have been made by the author (Bhattacharjee, 2002, 2008, 2011, 2008). In Bhattacharjee, 2002, a means of removing the most misleading sign convention of geometrical optics has been pointed out with the help of vector algebra. View full abstract»

  • An Alternative Technique for Solving Impedance Matching Problems on the Smith Chart

    The ultimate goal of impedance matching is to minimize the reflection coefficient between a known source output impedance and an arbitrary load impedance connected by a transmission line of a known characteristic impedance, thereby achieving maximum power transfer. This can be accomplished by the means of a low-loss matching network. There are a number of different techniques that can be used to solve the impedance matching problem. View full abstract»

  • New Power-Aware Multicast Algorithm for Mobile Ad Hoc Networks

    A mobile ad hoc network (MANET) is a decentralized network that consists of mobile nodes. Each node operates with the limited battery power to forward the data packets from the source to a group of the nodes. In a MANET, multicast is a very useful communication system for group-oriented applications, where one-tomany propagations are needed frequently in critical situations. This article presents a new power-aware multicasting algorithm for MANETs. Here, it uses the residual battery energy for the multicasting from the source to a group of destinations. The proposed model increases the lifetime of the nodes and the network lifetime. The simulation work shows better results in terms of the node lifetime and network lifetime as compared to other models, ODMRP and AMRoute. If the group size is 12, then the proposed model has kept the nodes alive for 8,100 s, whereas the ODMRP and AMRoute models have kept the nodes alive for 7,400 s and 6,400 s respectively.

  • Using Different Encryption Techniques for Load Balancing with Cluster-Based Storage

    Cluster-based storage is a group of nodes that are linked together where each node is assumed as a server. Each node can work independently without affecting the other nodes, and the same file is present in each node. RSA, ElGamal, and ARIA are well-known encryption techniques, which are used to reduce the server load. Public and private keys are generated by the administrator dynamically and by using public keys. Files are encrypted after, and the same files are uploaded into the three servers. Users can select any files that are present in the database server. After selecting the appropriate file, the system dynamically calculates the minimum response time and starts downloading the file from the server, which has a minimum response time. Comparisons are also done between these encryption techniques in order to show the best encryption technique. View full abstract»

  • Frequency Domain Analysis of Envelope Detectors for AM (DSB-LC) Signals

    Amplitude modulation (AM) is a technique that relies on varying the amplitude of the RF carrier in accordance with the baseband signal. The signal is thus embedded in the carrier?s amplitude, and its spectrum becomes centered on the carrier frequency. The bandwidth of the modulated signal is double that of the baseband signal. To demodulate the AM signal, we adopt one of two possible detection approaches: coherent detection and noncoherent detection. Coherent detection relies on multiplying the received signal by a carrier identical to that used in the transmitter and then applying low-pass filtering to the resultant signal to extract the baseband signal. Noncoherent detection is carried out by tracing the envelope of the received signal to extract the baseband signal. View full abstract»
