"Optimal sensor network scheduling in identification of distributed parameter systems discusses the characteristic features of the sensor scheduling problem, analyzes classical and recent approaches, and proposes a wide range of original solutions, especially dedicated for networks with mobile and scanning nodes. Both researchers and practitioners will find the case studies, the proposed algorithms, and the numerical examples to be invaluable. "

"Questions about stability arise in almost every control problem. There are many physical problems in which exponential stability is too strong and for which the concept of strong stability is appropriate. This book provides a solid mathematical framework for a structured approach to strongly stabilizable systems through integration of fundamental theory, physical applications, and numerical results. The author includes a mathematical framework for studying PDE models of large flexible structures, an important class of applications.
The author's structured approach focuses on two themes: the development of system theoretic results for strongly stable systems, and the formulation of these results for a class of dissipative systems with collocated actuators and sensors. The tools set forth in this book extend the scope of applicability of PDE control techniques, including the important aspect of numerical approximation. Most importantly, the author justifies all theory by providing physical examples for which the theory is relevant.
The book encompasses basic system theoretic notions, such as stability, stabilizability, detectability, coprime factorizations, and control related topics like Riccati equations, LQ optimal control, robust stabilization, nonlinear perturbations, and numerical approximation."

"Research Directions in Distributed Parameter Systems is composed of eleven chapters, written by experts in their respective fields, on topics ranging from control of the Navier-Stokes equations to nondestructive evaluation all of which are modeled by distributed parameters systems. Written by the plenary speakers for the Conference on Future Directions in Distributed Parameter Systems (October 2000), the volume addresses the state of the art, open questions, and important research directions in applications modeled by partial differential equations and delay systems, with the ultimate goal of passing along these perspectives to researchers in the field.
This book compiles a broad range of material, much of which is available only in research journals. Its goal is to disseminate to the research community the perspectives and challenges posed for a variety of current research applications. Topics include electromagnetic theory for dielectric and conductive materials, flow control, cardiovascular and respiratory models, homogenization and systems theory, optimal and geometric control, reduced-order models for large-scale systems, smart materials, and nondestructive evaluation and structural health monitoring for systems, including nuclear power plants. A unifying theme throughout the book focuses on the necessity of considering model development, numerical approximation, parameter estimation through inverse problem techniques, and control design in concert to achieve the stringent design criteria dictated by present applications."

"This book focuses on scheduling algorithms for parallel applications on heterogeneous distributed systems, and addresses key scheduling requirements – high performance, low energy consumption, real time, and high reliability – from the perspectives of both theory and engineering practice. Further, it examines two typical application cases in automotive cyber-physical systems and cloud systems in detail, and discusses scheduling challenges in connection with resource costs, reliability and low energy.
The book offers a comprehensive and systematic treatment of high-performance, low energy consumption, and high reliability issues on heterogeneous distributed systems, making it a particularly valuable resource for researchers, engineers and graduate students in the fields of computer science and engineering, information science and engineering, and automotive engineering, etc. The wealth of motivational examples with figures and tables make it easy to understand.

"Sistem komunikasi merupakan salah satu bagian penting pada Wireless Sensor Network (WSN), karena sistem komunikasi tersebut dapat mendukung proses pengiriman data traffic dari beberapa grup sensor traffic surveillance ke Base Station. Umumnya, Zigbee adalah standar yang digunakan untuk protokol komunikasi wireless dengan menggunakan radio digital berukuran kecil dan berdaya rendah yang memiliki standar IEEE 802.15.4.
Pada penelitian ini telah dirancang pemodelan scheduling protocol sensor AMR dan video kamera dengan menggunakan metode queueing CBQ (Class Based Queueing) dan algoritma scheduling WRR (Weighted Round Robin) untuk memperoleh performansi QoS (Quality of Service) sistem dari segi throughput, packet delivery ratio, dan packet loss rate yang lebih baik. Simulasi pemodelan scheduling protocol dilakukan menggunakan software Netwok Simulator (NS-2) dengan dua skenario simulasi yaitu skenario perubahan interval transmisi dan skenario perubahan ukuran payload paket data. Analisis yang dilakukan adalah saat sistem menggunakan pemodelan scheduling protocol yang dirancang dan tanpa scheduling protocol.
Hasil penelitian ini, diperoleh pada skenario perubahan interval transmisi mempunyai throughput paling bagus dari grup sensor video sebesar 36,008 Kbps pada interval transmisi 0,02 detik, packet delivery ratio sebesar 99,915 %, dan packet loss rate sebesar 0,0845 %. Sedangkan, pada skenario perubahan ukuran payload paket data diperoleh throughput grup sensor video sebesar 91,368 Kbps pada ukuran paket 100 byte, packet delivery ratio sebesar 99,94 % pada ukuran 50 byte, dan packet loss rate 0,06 % pada ukuran 50 byte. Pemodelan scheduling protocol pada penelitian ini dapat meningkatkan throughput rata-rata sekitar 96,80 % - 388,25 %, meningkatkan packet delivery ratio rata-rata sekitar 25,5 % - 51,6 %, serta mengurangi packet loss rate rata-rata sekitar 58,51 % - 73,16 %.

Communication system is an essential part in Wireless Sensor Network (WSN), because it supports sending traffic data between groups of traffic surveillance sensor and the base station. Generally, ZigBee is a standard that is used in wireless communication protocols using small-sized and low power digital radio which has the IEEE 802.15.4 standard.
In this research, the scheduling protocol modeling of AMR and camera video is proposed using CBQ (Class Based Queueing) queueing method and WRR (Weighted Round Robin) scheduling algorithm. The proposed modelling aim to obtain QoS (Quality of Service) system performance that is better throughput, packet delivery ratio and packet loss rate. This modelling schedulling protocol is simulated by using the Network Simulator (NS-2) software. The simulation scenarios are varying the transmission intervals and changing packet data payload size. The simulation analysis are comparing when use scheduling protocol modeling and without scheduling protocol modeling.
The result of this research are in transmission interval scenario achieved by video sensor group which have the best throughput is 36.008 kbps in transmission interval 0.02 second. The packet delivery ratio is 99.915%. The packet loss rate is 0.0845%. In payload size of packet data scenario, the best throughput achieved by video sensor group is 91.368 kpbs in the packet size of 100 byte. The packet delivery ratio is 99.94% in size of 50 byte. The packet loss rate is 0.06% in the packet size of 50 byte. Modeling of scheduling protocol in this research can improve QoS (Quality of Service) system. Increase average throughput is about 96.80 % - 388,25 %. Increase average packet delivery ratio is about 25,5 % - 51,6 %. Decrease average packet loss rate is about 58,51 % - 73,16 %."
