  • Monopole Floer homology is used to prove that real projective three-space cannot be obtained from Dehn surgery on a nontrivial knot in the three-sphere. To obtain this result, we use a surgery long exact sequence for monopole Floer homology, together with a nonvanishing theorem, which shows that monopole Floer homology detects the unknot. In addition, we apply these techniques to give information about knots which admit lens space surgeries, and to exhibit families of three-manifolds which do not admit taut foliations. ...

  • Receiver System Parameters A receiver picks up the modulated carrier signal from its antenna. The carrier signal is downconverted, and the modulating signal (information) is recovered. Figure 5.1 shows a diagram of typical radio receivers using a double-conversion scheme. The receiver consists of a monopole antenna, an RF amplifier, a synthesizer for LO signals, an audio amplifier, and various mixers, IF amplifiers, and filters.

  • THIS book is pragmatical, not philosophical; a practical manual, not a treatise upon theories. It is intended for the men and women whose most pressing need is for money; who wish to get rich first, and philosophize afterward. It is for those who have, so far, found neither the time, the means, nor the opportunity to go deeply into the study of metaphysics, but who want results and who are willing to ...

  • 4 Forensic Techniques Used in Environmental Litigation Scientific method vs. junk science 4.1 INTRODUCTION When evaluating the merits of performing non-intrusive forensic analysis (e.g., contaminant transport modeling or aerial photo-interpretation) and/or intrusive sampling and testing, three questions should be considered: 1. Does the analysis or testing advance the understanding of the technical aspects of the case? 2. Can the test results be damaging to your client? 3.

  • India’s markets are monopolized in only a few areas reserved for the public sector, such as postal services, defense, atomic energy and railways. The government is considering gradual private participation in areas reserved for exclusive state ownership. Monopolies are rare in activities open to the private sector. The Competition Act, 2002 prohibits anti-competitive agreements, including the formation of cartels and the sharing of territories, restrictions of production and supply, collusive bidding and bid rigging and predatory pricing.

  • This paper concentrates on studying, designing and manufacturing a dual – band and high – bandwidth antenna applied for advance mobile handsets. This antenna can work in GSM/UMTS bands by generating two resonant modes of 900 MHz and 1900 MHz frequencies. Antenna is printed on FR4 substrate with size of 58 mm x 80 mm, thickness of 1.6 mm and relative permittivity of 4.4. The propose antenna is experimentally studied. Keywords: Antenna, dual-band, monopole, microstrip antenna.
