Development of an automated ultrasonic inspection cell for detecting subsurface discontinuities in cast iron
Manufacturing of value added products by companies in todays global marketplace requires the vendors to meet certain minimum standards, SAE, ASTM, ISO, etc. In a global economy, as a manufacturer for the year 2000 and beyond, preferred vendors will become ISO 9000 certified to maintain a market share of produced goods. An automated inspection cell was developed for the inspection of cast iron ports to detect subsurface discontinuities. The cell consists of an ultrasonic flaw detector (UFD), transducer, robot, immersion tank, computer, and software. Normal beam pulse-echo ultrasonic nondestructive testing is performed on each rough casting. Using test blocks and castings supplied by an industrial partner and working with a skilled ultrasonic inspector; ultrasonic transducer selection, initial inspection criteria, and UFD setup parameters were developed for the gray iron castings used in this study. The skilled ultrasonic inspector's operation of the UFD was noted for development of the cell software. The ultrasonic inspection cell control software (UICCS) was designed and developed to perform the necessary functions for control of the robot and UFD in real-time. The UICCS performed two main tasks; emulating the manual operation of the UFD through the communication link with the unit, and evaluation of the ultrasonic signatures for detection of subsurface discontinuities. The next phase of the cell development involved the testing of a lot of 105 castings. These casting were processed through the inspection cell. The castings which passed the inspection criteria were returned to the manufacturer for machining into finished parts where they were visibly inspected for defects after machining. The castings that had ultrasonic signatures consistent with subsurface discontinues were manually inspected by the skilled ultrasonic inspector, with the manual inspection time recorded for comparison to the automated cycle time. The castings then were inspected using destructive testing techniques for detecting subsurface material voids. The developed automated inspection cell correctly classified the inspection locations 99.8% of the time. Compared to manual inspection (as measured in the study), the automated cell's cycle time was 30 times more efficient.

Breaking new territory.(writing original children's fiction)
A children's author an illustrator who breaks new ground with each book, instead of writing sequels or series, describes his process of fleshing out ideas and illustrations. His work habits have improved over time, but he is still disorganized. Being a parent has helped write from a child's view.

Four Factors of Hardening Repeater Sites and Networks to Support Emergency Communications
The IP-based networks typically use commercial ISPs (Internet Service Providers), WISPs (Wireless Internet Service Providers), cellular/PCS 3G/4G/5G, and satellite for their connectivity, all of which have monthly service expenses. All these connectivity options are also prone to failure and overloading during emergencies (see the sidebar, \"An Amateur Radio Solution for Internet Outages\"). Since the advent of cellular/PCS technology, use of autopatch technology is rare. Besides hardening the repeater networks, there is also a cost savings involved.

Introduction to Digital Mobile Radio (DMR)
Digital voice involves the conversion of analog voice into a digital data stream for transmission over the RF or wired media. Any Tier III capable radio will also work on Tier II systems but neither will work on Tier I. Digital vs Analog If you operate on analog FM repeaters, you will have noticed that the audio quality degrades as a signal into the repeater (uplink) gets weaker. A basic difference with digital repeaters is that the audio quality remains the same on the uplink and downlink until the very edge of the coverage range.\\n I recommend a handheld transceiver for your first DMR radio unless you live beyond handheld coverage of your local DMR repeater.
