Raja was the 2011–2012 chair of the IEEE Humanitarian Activities Committee. He wanted to find a way to mobilize engineers to apply their expertise to develop sustainable solutions that help their local community. To achieve the goal, in 2011 he founded IEEE SIGHT. Today there are more than 150 SIGHT groups in 50 countries that are working on projects such as sustainable irrigation and photovoltaic systems.
For his efforts, he received the 2015 Larry K. Wilson Transnational Award from IEEE Member and Geographic Activities. The award honors effective efforts to fulfill one or more of the MGA goals and strategic objectives related to transnational activities.
For the past two years, Rajah chaired the IEEE Admission and Advancement Review Panel, which approves applications for new members and elevations to higher membership grades.
He was a member of the International Centre for Free and Open Source Software’s advisory board. The organization was established by the government of Kerala, India, to facilitate the development and distribution of free, open-source software. Raja also served on the board of directors at Bedroc, an IT staffing and support firm in Nashville.
He earned his bachelor’s degree in chemical engineering in 1979 from the Indian Institute of Technology in Delhi.
Donn S. Terry
Life member, 74; died 14 September
Terry was a computer engineer at Hewlett-Packard in Fort Collins, Colo., for 18 years.
He joined HP in 1978 as a software developer, and he chaired the Portable Operating System Interface (POSIX) working group. POSIX is a family of standards specified by the IEEE Computer Society for maintaining compatibility among operating systems. While there, he also developed software for the Motorola 68000 microprocessor.
Terry left HP in 1997 to join Softway Solutions, also in Fort Collins, where he developed tools for Interix, a Unix subsystem of the Windows NT operating system. After Microsoft acquired Softway in 1999, he stayed on as a senior software development engineer at its Seattle location. There he worked on static analysis, a method of computer-program debugging that is done by examining the code without executing the program. He also helped to create SAL, a Microsoft source-code annotation language, which was developed to make code design easier to understand and analyze.
Terry retired in 2014. He loved science fiction, boating, cooking, and spending time with his family, according to his daughter, Kristin.
He earned a bachelor’s degree in electrical engineering in 1970 and a Ph.D. in computer science in 1978, both from the University of Washington in Seattle.
Signal processing engineer
Life senior member, 70; died 25 August
Sandham applied his signal processing expertise to a wide variety of disciplines including medical imaging, biomedical data analysis, and geophysics.
He began his career in 1974 as a physicist at the University of Glasgow. While working there, he pursued a Ph.D. in geophysics. He earned his degree in 1981 at the University of Birmingham in England. He then joined the British National Oil Corp. (now Britoil) as a geophysicist.
In 1986 he left to join the University of Strathclyde, in Glasgow, as a lecturer in the signal processing department. During his time at the university, he published more than 200 journal papers and five books that addressed blood glucose measurement, electrocardiography data analysis and compression, medical ultrasound, MRI segmentation, prosthetic limb fitting, and sleep apnea detection.
Sandham left the university in 2003 and founded Scotsig, a signal processing consulting and research business, also in Glasgow.
He served on the editorial board of IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing and the EURASIP Journal on Advances in Signal Processing.
He was a Fellow of the Institution of Engineering and Technology and a member of the European Association of Geoscientists and Engineers and the Society of Exploration Geophysicists.
Sandham earned his bachelor’s degree in electrical engineering in 1974 from the University of Glasgow.
Stephen M. Brustoski
