Abstract: This article explains the recent trend in heart-rate and fitness monitors to go wireless toeliminate cables to allow free movement, and allow convenient data collection without the need to plug intheir devices. It details a typical wireless system, using the MAX1472 crystal-referenced phase-lockedloop (PLL) VHF/UHF transmitter.
The tar file contains the following files:
ptfsf.c: heart of the perfect TFSF code
ptfsf.h: header file for same
ptfsf-demo.c: FDTD code which demonstrates use of perfect TFSF code. Essentially this program used to generate results shown in the paper
ptfsf-file-maker.c: code to generate an incident-field file using the "perfect" incident fields
ptfsf-demo-file.c: FDTD code which uses the perfect incident fields stored in a file
fdtdgen.h: defines macros used in much of my code
Makefile: simple make-file to compile programs
Also include are some simple script files to run the programs with reasonable values.
The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.)
Application & Integration Services are at the heart of any Service Oriented Architecture (SOA). Sun Java System Application Server and integration services provide a highly scalable and reliable platform for the standards-based deployment of Java applications and web services. Sun s offerings may be used by small organizations and large enterprises that require a services-based foundation to rapidly unlock the business value of their IT investment.
Techniques for storing and processing data are at the heart of all programs. The term data structure is used to describe the way data is stored, and the term algorithm is used to describe the way data is processed.
At the heart of Java technology lies the Java virtual machine--the abstract computer on which all Java programs run. Although the name "Java" is generally used to refer to the Java programming language, there is more to Java than the language. The Java virtual machine, Java API, and Java class file work together with the language to make Java programs run.
