"A discussion of some topics in the theory of large deviations such as moment-generating functions and Chernoff's theorem, and of aspects of estimation and testing in large samples, such as exact slopes of test statistics."

"Population processes are stochastic models for systems involving a number of similar particles. Examples include models for chemical reactions and for epidemics. The model may involve a finite number of attributes, or even a continuum. This monograph considers approximations that are possible when the number of particles is large. The models considered will involve a finite number of different types of particles."

"Sering terjadinya kasus kelongsoran timbunan sampah di Indonesia membuat analisis stabilitas timbunan menjadi salah satu upaya penting dalam pemenuhan aspek keamanan bagi tempat pembuangan sampah. Namun, kurangnya data mengenai parameter kuat geser sampah yang sesuai dengan karakteristik sampah Jakarta membuat analisis tersebut sulit dilakukan. Penelitian ini bertujuan untuk melakukan studi parametrik stabilitas timbunan sampah TPST Bantar Gebang dengan menggunakan program Slope/W untuk memperkirakan parameter kuat geser sampah. Parameter kuat geser sampah diantaranya dipengaruhi oleh komposisi sampah dan umur sampah tersebut. Semakin tua umur sampah, maka semakin kecil nilai kohesi dan semakin besar nilai sudut geser. Faktor keamanan yang didapatkan pada studi parametrik dengan metode Morgenstern-Price lebih besar dibandingkan metode Ordinary, Janbu, Bishop, dan Finite Element. Selain itu, juga dilakukan simulasi kondisi kritis dan simulasi geometri timbunan sampah. Hasilnya menunjukkan bahwa peningkatan kadar air, sudut kemiringan, dan tinggi timbunan membuat timbunan menjadi lebih tidak stabil. Hasil tersebut dapat menjadi saran bagi pengelola TPST Bantar Gebang.

Frequent occurrence of landfill landslide cases in Indonesia make stability analysis be one of the important efforts to fulfill safety aspect for landfill. However, the lack of shear strength parameters data according to the characteristics of the Jakarta Municipal Solid Waste (MSW), makes the analysis difficult to do. This study aims to conduct a parametric study of stability on Bantar Gebang landfill by using program Slope/W to estimate shear strength parameters. Shear strength parameters are influenced by the MSW composition and the age of the waste. The older age of the waste, makes the cohesion is smaller and the friction angle is greater. Safety factor which is reached on parametric study by Morgenstern-Price method is greater than Ordinary, Janbu, Bishop, and Finite Element method. This study also conducts the critical condition simulations and landfill’s geometry simulations. The results show that the increase in water level, slope angle, and height of the slope, make the slope becomes more unstable. It may be suggestion for the managers of TPST Bantar Gebang."

"Regulasi price limit seharusnya dapat mengurangi gejala volatilitas harga saham yang berlebihan ketika market dalam keadaan crash. Mengacu pada penelitian Kim (1997) dan Huang (2001) penelitian ini dimaksudkan untuk melihat efektifitas regulasi price limit yang diterapkan di Bursa Efek Indonesia selama periode 2007-2008. Jika memang price limit terbukti mengurangi volatilitas maka overreaction hypothesis yang dikemukakan oleh Huang (2001) akan terbukti. Tetapi jika tidak, penelitian ini kemudian dikembangkan mengacu pada penelitian Kim (1997) untuk menguji ketiga hipotesis masalah baru yang muncul akibat adanya regulasi price limit. Ketiga hipotesis tersebut adalah volatility spillover hypothesis, delayed price discovery hypothesis, dan trading interference hypothesis.

Daily price limits should reduce volatility of the stock price where market had crashed. Refers to research conducted by Kim (1997) and Huang (2001), this research is intended to see the effectiveness of price limits on the Indonesia Stock Exchange during the 2007-2008 period. If price limit is effective to reduce the volatility of the stock prices, then overreaction hypothesis stated by Huang (2001) will be proved. But if not, this research will be extended based on Kim?s (1997) to test the three new hypotheses of new issues that arise due to price limits. The three hypotheses are volatility spillover hypothesis, delayed price discovery hypothesis, dan trading interference hypothesis."

"This book establishes the theory of how to go about estimating not just scalar parameters about a proposed model, but also the underlying structure of the model itself. Classic statistical tools are used, the law of large numbers, and the central limit theorem. Researchers have recently developed creative and original methods to use these tools in sophisticated (but highly technical) ways to reveal new details about the underlying structure. This book will be of special interest to researchers, combining the theory of mathematical finance with its investigation using market data, and it will also prove to be useful in a broad range of applications, such as to mathematical biology, chemical engineering, and physics.
