A Coded message for help from Jim's father on Earth sent to Kharlor, naming Jim and Ali. The FTL Battle Cruiser Aurora is sent. They find Jano Dagar is planning to wreck Earth by mining for the... More > laser-weapon-enhancing mineral Dwaafmite. But Jano is planning more. He aims to completely destroy Earth by exploding Planet-buster bombs in Yellowstone Park to create a super-volcano and explode more at places in the Ring of Fire to shift the Tectonic Plates. It takes all the resources of the Aurora and Earth to have any chance of stopping him. Jim and Ali are in the front line in fereting out Jano's plans and combatting them, even when they are taken prisoner< Less
A Coded message is sent to Jim Atkins and Ali Mukbar at the Kharlor Space Academy by Professor Atkins on Earth. The Emperor sends the FTL Battle Cruiser with Jim and Ali. The danger is far greater... More > than had ever been thought. To Kharlor if the Dagar Confederation successfully mine the laser-weapon enhancing mineral, Dwarfmite. And to Earth itself. If Jano Dagar's Plan succeeeds the planet Earth will be shattered. It takes all the resources of the Aurora, Earth and Jim and Ali to find out the details of the Plan, but can they stop it in time as the last minutes tick away?< Less

Based on the Jewish comic strip 4 Corners, Zeyde And The Hidden Mine is the story of four best friends who go on a summer adventure only to find that they have become trapped in an old mine. Zeyde... More > (Yiddish for Grandfather), their favorite adult, finds them and becomes trapped himself. While they wait for rescue, they learn about Zeyde's life, and his survival of the Holocaust. This story was written as an entertaining adventure, and a way to introduce young people to the subject of the Holocaust without the horrific details and images.< Less
On a distant world far from the Imperial heartland a cruel dictator runs a harsh world with an iron fist. Those who support him are rewarded yet any dissidents are quickly sent to the mines.

Follow her as she grows up in this environment unaware a stranger is willing to spend years crossing the Galaxy to save her. But why?< Less
Based on the author's PhD thesis, this book is a theoretical study of subterranean radio communication, with the focus on methods that depend primarily on the penetration of electromagnetic fields... More > through the ground. Through-the-earth communication using e-m fields - specifically magnetic induction - plays a role in search and rescue systems used in the mining industry. It is also used for borehole telemetry, pipeline location and by cavers and pot-holers. Chapters describe propagation, antennas, and the design of transmitters and receivers. A figure of merit - the specific aperture - is introduced as an aid to antenna design. A crucial aspect of all systems is the signal to noise ratio, for which the strategy of noise-matching is introduced. The design of a wide-band low-frequency sounder is described, for channel evaluation using a non-ideal binary sequence. A method of calculating the inverse of a generalised sequence is described, for which cross-correlation results in a system identification signal.< Less
