Abstrak :
This versatile book teaches control system design using H∞infty techniques that are simple and compatible with classical control, yet powerful enough to quickly allow the solution of physically meaningful problems. The authors begin by teaching how to formulate control system design problems as mathematical optimization problems and then discuss the theory and numerics for these optimization problems. Their approach is simple and direct, and since the book is modular, the parts on theory can be read independently of the design parts and vice versa, allowing readers to enjoy the book on many levels. The development of H∞infty engineering was one of the main accomplishments of control in the 1980s. However, until now, there has not been a publication suitable for teaching the topic at the undergraduate level. This book fills that gap by teaching control system design using H∞infty techniques at a level within reach of the typical engineering and mathematics student. It also contains a readable account of recent developments and mathematical connections. The authors treat control design problems in a physically correct way. They present a small set of specific rules that the reader can apply to convert a particular design problem to the fundamental optimization problem of H∞infty control. This precisely formulated mathematics problem can then be solved on a computer. The book introduces the control software package OPTDesign, which allows the reader to easily reproduce the calculations done in the solved examples and even try variations on them. The description of how to convert an engineering problem to a form suitable for CAD is simpler than in other books.

Abstrak :
One of the main accomplishments of control in the 1980s was the development of H∞ techniques. This book teaches control system design using H∞ methods. Students will find this book easy to use because it is conceptually simple. They will find it useful because of the widespread appeal of classical frequency domain methods. Classical control has always been presented as trial and error applied to specific cases; Helton and Merino provide a much more precise approach. This has the tremendous advantage of converting an engineering problem to one that can be put directly into a mathematical optimization package. After completing this course, students will be familiar with how engineering specs are coded as precise mathematical constraints.

Abstrak :
Zeolit alam adalah mineral yang memiliki sifat khas dan struktur rongga yang teratur dalam ukuran tertentu, sehingga berpotensi sebagai adsorben limbah amonia. Kapasitas adsorpsi dan selektivitgasnya dapat ditingkatkan degnan modifikasi zeolit alam melalui proses pertukaran ion menjadi H-Zeolit yang memiliki inti aktif H. Penelitian ini menggunakan zeolit alam yang berada dari Lampung yang mengandung klinoptilolit sekitar 75%. kapasitas adsi=orpsi Zeolit alam Lampung (ZAL) diperbandingkan dengan tiga jenis H-Zeolit yang dihasilkan dari proses pertukaran ion antara ZAL dengan NH4NO3 dan (NH4) SO4 dan kemudian dikalsinasi pada suhu 550 C. Adsorpsi dilakukan secara batch pada suhu dan tekanan kamar dengan variasi waktu dan konsentrasi awal amonia. Dilakukan pula percobaan regenarasi terhadap zeolit yang telah jenuh dengan NH3, dengan jalan pemanasan pada suhu 550 C selama 1 jam dan selamanya digunakan kembali untuk adsorpsi. Sebagai tahap awal adsorpsi regenerasi dilakukan sebanyak dua setengah siklus. Hasil penelitian ini menunjukkan bahwa dari segi kapasistas adsorpsi dalam pemakaian siklus adsorpsi regenerasi, H-zeolit lebih baik dari pada zeolit alam setelah regeneraasai zeolit alam mengamalami penurunan kapasista adsorps yang cukup besar. Secara umum H Zeolit yang diperoleh dari aktivasi dengan amonium nitrat merupakan zeolit yang paling baik jika digunakan sebagai adsorben amonia. Perlu dilakukan percobaan lebih lanjut menggunakan air limbah atau limbah tiruan untuk mengetahui kapasitas adsorpsi maupun selektivitasnya dengan siklus adsorpsi yang lebih panjang.

Abstrak :
This monograph presents a unified mathematical framework for a wide range of problems in estimation and control. The authors discuss the two most commonly used methodologies: the stochastic H2 approach and the deterministic (worst-case) H� approach. Despite the fundamental differences in the philosophies of these two approaches, the authors have discovered that, if indefinite metric spaces are considered, they can be treated in the same way and are essentially the same.

Abstrak :
Latar belakang: Terapi sel punca dikembangkan sebagai alternatif terapi gagal jantung akibat infark miokardium. Bermacam tipe sel dengan berbagai metode implantasi telah banyak dikembangkan tetapi belum mendapatkan hasil optimal. Sel h-AECs (Human Amnion Epithelial Stem Cells) memiliki sifat yang sangat mendukung sebagai sumber sel bagi terapi sel punca pada jantung. Teknologi rekayasa jaringan dengan melakukan ko-kultur kardiomiosit dan h-AECs pada biomaterial scaffold diyakini dapat menjawab permasalahan pada pengembangan terapi sel punca pada gagal jantung. Metode: Penelitian ini adalah studi eksperimental in-vitro dengan penyemaian ko-kultur sel kardiomiosit dan h-AECs ke dalam scaffold patch. Kardiomiosit berasal dari otot ventrikel kanan pasien penderita penyakit tetralogy of Fallots yang dilakukan operasi koreksi TOF. Sedangkan sel h-AECs didapat dari epitel amnion yang merupakan limbah operasi seksio sesarea. Setelah dilakukan karakterisasi pada kardiomiosit dan h-AECs, dilakukan ko-kultur pada scaffold amnion dengan perbandingan densitas penyemaian 1:5 dan 1:6. Evaluasi hasil ko-kultur dilakukan dengan penilaian viabilitas sel, ekspresi gen spesifik kardiomiosit dan uji toksisitas patch. Hasil: Hasil ko-kultur kardiomiosit dan h-AECs tidak terdapat perbedaan bermakna pada rerata jumlah sel viabel pada hari kedua dan kelima (p>0,05). Sedangkan pada hari kedelapan terdapat perbedaan bermakna pada jumlah sel viabel, rasio 1:5 menghasilkan jumlah sel viabel lebih baik dibanding rasio 1:6 (p=0,011). Ekspresi gen spesifik kardiomiosit konsisten tampak pada kelompok rasio 1:6 dan mulai menunjukkan signifikan pada hari kedelapan, terdapat perbedaan bermakna pada ekspresi gen di hari kedelapan, kelompok rasio 1:6 mengekspresikan gen cTnT dan ACTN2 lebih baik dibanding kelompok 1:5 (p=0,000 dan p=0,001). Pada uji toksisitas, tidak terdapat perbedaan bermakna pada jumlah ATP dan kadar TNFα antara kelompok 1:5 dan 1:6. Simpulan: Teknik ko-kultur yang dikembangkan dapat menghasilkan sel kardiomiosit baru. Kelompok rasio 1:6 menghasilkan sel yang memiliki sifat spesifik kardiomiosit lebih baik dibanding kelompok rasio 1:5 tetapi menghasilkan jumlah sel viabel lebih sedikit. Patch hasil ko-kultur tidak bersifat toksik. ......Background: Stem cell therapy was developed as an alternative therapy for heart failure due to myocardial infarction. Various types of cells with various methods of implantation have been developed but have not yet obtained optimal results. h-AECs (Human Amnion Epithelial Stem Cells) have very supportive properties as a source of cells for stem cell therapy in the heart. Tissue engineering technology by co-culturing cardiomyocytes and h-AECs on scaffold biomaterials is believed to be able to answer problems in the development of stem cell therapy in heart failure. Method: This study is an in-vitro experimental study by seeding co-cultures of cardiomyocytes and h-AECs into the scaffold patch. Cardiomyocytes were derived from the right ventricular muscle of patients with tetralogy of Fallot disease who underwent TOF correction surgery. Meanwhile, the h-AECs cells were obtained from the amniotic epithelium which is the waste from cesarean section. After characterization of cardiomyocytes and h-AECs, co-culture was performed on amnion scaffold with seeding density ratio 1:5 and 1:6. Evaluation of co-culture results was carried out by assessing cells viability, expression of specific cardiomyocytes gen and patch toxicity tests. Result: The results of co-culture of cardiomyocytes and h-AECs showed no significant difference in the mean number of viable cells on the second and fifth days (p>0.05). While on the eighth day there was a significant difference in the number of viable cells, a ratio of 1:5 resulted in a better number of viable cells than a ratio of 1:6 (p=0.011). Cardiomyocyte-specific gene expression was consistently seen in the 1:6 ratio group and began to show significantly on the eighth day, there was a significant difference in gene expression on the eighth day, the 1:6 ratio group expressed cTnT and ACTN2 genes better than the 1:5 group (p= 0.000 and p=0.001). In the toxicity test, there was no significant difference in the amount of ATP and TNFα levels between the 1:5 and 1:6 groups. Conclusion: The developed co-culture technique can generate new cardiomyocytes. The 1:6 ratio group produced cells that had better cardiomyocyte-specific properties than the 1:5 ratio group but produced fewer cells. Co-culture of h-AECs and cardiomyocytes on patch was not toxic.
