  • We give a new construction of the moonshine module vertex operator algebra V , which was originally constructed in [FLM2]. We construct it as a framed VOA over the real number field R. We also offer ways to transform a structure of framed VOA into another framed VOA. As applications, we study the five framed VOA structures on VE8 and construct many framed VOAs including V from a small VOA. One of the advantages of our construction is that we are able to construct V as a framed VOA with a positive definite invariant bilinear form and we...

  • Putting some real numbers around this provides more color. A fund with $200 million in AUM and zero or negative performance would generate revenue of $3 million. A return of 5% bumps the total revenue up to $5 million. With a 7.5% return, the fund’s revenues are $6 million: $3 million from the management fee and $3 million from the performance fee. Beyond the 7.5% performance mark, the incentive fee becomes the primary revenue contributor. The performance fee effect is what makes the hedge fund model so appealing and unique.

  • Connecting: The learning activities are designed to allow students of all ability levels to connect new mathematical ideas to what they already understand. The learning activity descriptions provide guidance to teachers on ways to help students make connections among concrete, pictorial, and symbolic mathematical representations. Advice on helping students connect procedural knowledge and conceptual understanding is also provided. The problem-solving experiences in many of the learning activities allow students to connect mathematics to real-life situations and meaningful contexts....

  • Real-time Transport Protocol (RTP) is the protocol designed to handle real-time traffic on the Internet. RTP does not have a delivery mechanism (multicasting, port numbers, and so on); it must be used with UDP. RTP stands between UDP and the application program. The main contributions of RTP are timestamping, sequencing, and mixing facilities. This chapter provides knowledge of RTP and RTCP.

  • The Listening and Reading Test is scored by calculating the correct number of answer choices. The raw number of correct answers is converted to a scaled score, which compares an individual’s raw score with the raw score of other test takers. This makes allowances for the difficulty level of any particular test administration.

  • Because I’ve been the product manager of Adobe Illustrator, people frequently approach me who, prior to attending a demo or workshop on Illustrator, either thought they had no need for the program or were under the impression it is used only for designing logos. The truth is, Illustrator is essential to a broad range of professionals and hobbyists, and it has an incredible number of uses—so many that it’s hard to defi ne exactly what Illustrator does.

  • Headway is a key input in calculating the overall route capacity of any transit system. A system that requires large headways has more empty space than passenger capacity, which lowers the total number of passengers or cargo quantity being transported for a given length of line (railroad or highway, for instance). In this case, the capacity has to be improved through the use of larger vehicles. On the other end of the scale, a system with short headways, like cars on a freeway, can offer very large capacities even though the vehicles carry few passengers....

  • There are many DSP applications that are used in our daily lives, some of which have been introduced in previous chapters. DSP algorithms, such as random number generation, tone generation and detection, echo cancellation, channel equalization, noise reduction, speech and image coding, and many others can be found in a variety of communication systems. In this chapter, we will introduce some selected DSP applications in communications that played an important role in the realization of the systems. ...

  • Di®erent types of numbers ¯nd di®erent application in the physical world. Whole numbers work well for counting discrete objects, such as the number of resistors in a circuit. Integers are needed when negative equivalents of whole numbers are required. Irrational numbers are numbers that cannot be exactly expressed as the ratio of two integers, and the ratio of a perfect circle's circumference to its diameter (¼) is a good physical example of this.

  • Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic[1] – do not vary smoothly in this way, but have distinct, separated values.

  • Signals can be divided into three categories ± continuous-time (analog) signals, discrete-time signals, and digital signals. The signals that we encounter daily are mostly analog signals. These signals are defined continuously in time, have an infinite range of amplitude values, and can be processed using electrical devices containing both active and passive circuit elements. Discrete-time signals are defined only at a particular set of time instances. Therefore they can be represented as a sequence of numbers that have a continuous range of values. ...
