Molter, H. Gregor
"H. Gregor Molter develops a hardware / software co-design flow based on the Discrete Event System Specification model of computation. He advocates that such a system level design flow should exploit a timed model of computation to allow a broad application field. The presented design flow will transform timed DEVS models to both synthesizable VHDL source code and embeddable C++ source code."

"Low Noise Amplifier (LNA) dan Bandpass Filter (BPF) merupakan bagian depan rangkaian radio frequency (RF) pada sebuah receiver maupun RF field detector. Rancangan rangkaian dual band LNA dan BPF merupakan solusi menggabungkan dua perangkat dengan frekuensi kerja yang berbeda menjadi sebuah perangkat multi fungsi dan memiliki kemampuan dual band secara simultan.
Pada tesis ini membahas rancang bangun rangkaian co-design dual band LNA dan BPF pada Radio Navigation Aids (RNA) khususnya peralatan Very High Frequency Omni Range (VOR) / Instrument Landing System Localizer (ILS LOC) yang bekerja pada band VHF 108 - 118 MHz dan ILS Glide Slope (GP) pada band UHF 328,6 MHz ? 335,4 MHz yang digunakan untuk monitoring ground check. Rangkaian co-design adalah rangkaian LNA dan BPF yang digabungkan dalam sebuah rangkaian.
Bandpass filter yang dirancang juga berfungsi sebagai pengganti output matching impedance dari LNA, sehingga memiliki keuntungan komponen pasif menjadi lebih sedikit dan dimensi dari perangkat menjadi lebih kecil akan tetapi tetap memiliki spesifikasi parameter yang sama dengan rangkain dual band LNA dan BPF yang dipasang secara cascade (metode konvensional). Rancangan rangkaian co-design dual band LNA dan BPF disimulasikan, dipabrikasi, diukur dan dianalisa hasilnya. Sebagai pembanding juga dirancang rangkaian dual band LNA tanpa BPF dan rangkaian dual band LNAdan BPF secara cascade.
Hasil simulasi menunjukkan performa yang baik pada ketiga rangkaian dan masih memenuhi standar spesifikasi perancangan. Pada rangkaian co-design untuk frekuensi tengah 113,0 MHz dan frekuensi 332,0 MHz berturut turut didapatkan gain (S21) sebesar 24.116 dB/17.213 dB, input return loss (S11) sebesar -24.885 dB/-30.223 dB, noise figure sebesar 1.283 dB/ 1.250 dB, stability factor adalah 1.159 / 1.778 serta nilai VSWR mencapai 1.121 dan 1.064. Sedangkan hasil pengukuran fabrikasi peralatan nilai gain dan input return loss sedikit mengalami penurunan nilai dari hasil simulasi tetapi masih memenuhi standar spesifikasi perancangan untuk band VHF, namun pada band UHF masih diluar toleransi dari spesifikasi perancangan.

Low Noise Amplifier (LNA) and Bandpass Filter (BPF) are radio frequency (RF) frond-end circuit of a receiver or RF field detector. The design of dual-band LNA circuit and BPF are a solution to combining two devices with different working frequencies into a multi-function device and has simultaneous dual band capability.
This thesis discusses the design circuit co-design dual-band LNA and BPF at Radio Navigation Aids (RNA) in particular equipment Very High Frequency Omni Range (VOR) / Instrument Landing System Localizer (ILS LOC) working at band working on band VHF 108-118 MHz and ILS Glide Slope (GP) on band UHF 328.6 MHz - 335.4 MHz are used for ground check monitoring. The co-design is a series of LNA and BPF are combined in a circuit.
Bandpass filters are designed also serves as a substitute for the output matching impedance of the LNA, so it has the advantage of passive components becomes less and dimensions of the devices become smaller, but still have same performance with a dual-band LNA and BPF are designed in cascade by the conventional method. The circuit of co-design dual-band LNA and BPF simulated, fabricated, measured and analyzed the results. For comparison also designed a dual-band LNA circuit without dual band BPF and a dual band LNA and BPF in cascade.
Simulation results show good performance in all curcuits and still meet the design specifications. In a co-design for the center frequency of 113.0 MHz and 332.0 MHz frequencies obtained consecutive gain (S21) 24.116 dB/17.213 dB, input return loss (S11) -24.885 dB/-30.223 dB, noise figure 1.283 dB/ 1.250 dB, stability factor 1.159 / 1.778 and VSWR 1.121 dan 1.064. While the value of the measurement results of fabrication equipment and input return loss gain slightly decreased the value of simulation results but still meet the design specifications for the VHF band, UHF band but still out of tolerance from the design specifications.

"Model-Based Systems Engineering (MBSE), which tackles architecting and design of complex systems through the use of formal models, is emerging as the most critical component of systems engineering. This textbook specifies the two leading conceptual modeling languages, OPM—the new ISO 19450, composed primarily by the author of this book, and OMG SysML. It provides essential insights into a domain-independent,discipline-crossing methodology of developing or researching complex systems of any conceivable kind and size. Combining theory with a host of industrial, biological, and daily life examples, the book explains principles and provides guidelines for architecting complex, multidisciplinary systems, making it an indispensable resource for systems architects and designers, engineers of any discipline, executives at all levels, project managers, IT professionals, systems scientists, and engineering students.
Professor Dov Dori is Harry Lebensfeld Chair in Industrial Engineering and Head of the Enterprise System Modeling Laboratory at the Faculty of Industrial Engineering and Management, Technion, Israel Institute of Technology. Since 2000 he has been intermittently Visiting Professor at MIT's Engineering Systems Division, where he is currently Lecturer. He received his PhD in Computer Science in 1988 from Weizmann Institute of Science, MSc in Operations Research from Tel Aviv University in 1981, and BSc in Industrial Engineering and Management from Technion in 1975.
Professor Dov Dori invented and developed Object-Process Methodology (OPM), recently adopted as ISO 19450. He has authored over 300 publications, including journal and conference papers, books, and book chapters. Prof. Dori has mentored over 50 graduate students. He chaired or was co-chair of nine international conferences and workshops. Among his many editorial duties, Prof. Dori was Associate Editor of IEEE Transaction on Pattern Analysis and Machine Intelligence, and currently he is Associate Editor of Systems Engineering. He is Fellow of INCOSE – International Council on Systems Engineering, Fellow of IAPR – International Association for Pattern Recognition, Member of Omega Alpha Association – International Honor Society for Systems Engineering, and Senior Member of IEEE and of ACM. His research interests include model-based systems engineering, conceptual modeling of complex systems, systems architecture and design, software and systems engineering, and systems biology."
