"Dalam studi ini, efisiensi teknis dari industri garmen di DKI Jakarta diperkirakan dengan mengakomodasi terjadinyaefek ketidakefisienan teknis dalam suatu model stochastic frontier fungsi produksi. Tujuannya adalah untukmemperkirakan efisiensi teknis dari perusahaan sekaligus menjelaskan sumber-sumber penyebab ketidakefisienandalam konteks kebijakan ekonomi makro di Indonesia. Hasil empiris menampilkan beberapa gambaran yang menarikdari kinerja ekonomi perusahaan garmen dalam kaitan dengan karakteristik spesifik yang diperkirakanmempengaruhinya. Dalam penelitian ini terbukti fungsi produksi Cobb-Douglas tidak representatif dalam menjelaskankasus efisiensi teknis di DKI Jakarta, tetapi sumber-sumber ketidakefisienan dan adanya perubahan teknis dapatdibuktikan.In this paper, the technical efficiency of garment firms in DKI Jakarta is estimated by incorporating a model for thetechnical inefficiency effects in the stochastic frontier production function. The aims are to estimate both the technicalefficiency of the firms and the sources of technical inefficiency within the context of Indonesia?s macro-economicpolicy. The empirical results point a number of noteworthy features of the economic performance of firms in relationwith some specific characteristics. It is found in the study that the Cobb douglas functional form was not adequate, butthe sources of technical inefficiency were found and technical change was present."

"This memorial volume contains articles by prominent mathematicians in a variety of areas of the field, namely number theory, analysis, and geometry, representing Lang’s own breadth of interest and impact. A special introduction by John Tate includes a brief and fascinating account of the Serge Lang’s life. This volume's group of 6 editors are also highly prominent mathematicians and were close to Serge Lang, both academically and personally. The volume is suitable to research mathematicians in the areas of number theory, analysis, and geometry."

"The contributions in this volume, dedicated to the work and mathematical interests of Oleg Viro on the occasion of his 60th birthday, are invited papers from the Marcus Wallenberg symposium and focus on research topics that bridge the gap among analysis, geometry, and topology. The encounters among these three fields are widespread and often provide impetus for major breakthroughs in applications.Topics covered include new developments in low-dimensional topology related to invariants of links and three- and four-dimensional manifolds and the recent advances made in algebraic, complex, symplectic, and tropical geometry."

"This book is intended for advanced students and young researchers interested in the analysis of partial differential equations and differential geometry. It discusses elementary concepts of surface geometry in higher-dimensional Euclidean spaces, in particular the differential equations of Gauss-Weingarten together with various integrability conditions and corresponding surface curvatures. It includes a chapter on curvature estimates for such surfaces, and, using results from potential theory and harmonic analysis, it addresses geometric and analytic methods to establish the existence and regularity of Coulomb frames in their normal bundles, which arise as critical points for a functional of total torsion."
