An Economic Analysis of Technology-Capacity Alliances
Chien-Hung Kuo,Yon-Chun Chou 대한산업공학회 2008 대한산업공학회 추계학술대회논문집 Vol.2008 No.11
Globalization of production has altered the structure of many industries of intensive competition. This paper presents theoretical work on analyzing possible organization changes in manufacturing industries that provides capacity as services. We consider the case of tapered technology-capacity alliances between a process technology firm with captive manufacturing capability and an efficient manufacturing firm. We propose a framework of economic analysis which encompasses participation analysis, capacity allocation, and tradeoffs of contractual terms. Feasibility conditions for alliance formation are derived.

This paper presents the theoretical simulation of the response of 1020 carbon steel tubes subjected to symmetric and unsymmetric cyclic bending with or without external pressure by using the endochronic theory. Experimental data of 1020 carbon steel tubes tested by Corona and Kyriakides (1991) were used for evaluating the theoretical simulation. Several cases were considered in this study, they were symmetric bending without external pressure, symmetric bending with external pressure, unsymmetric bending without external pressure, and unsymmetric bending with external pressure. The responses of the moment-curvature, ovalization-curvature and ovalization-number of cycles with or without external pressure were discussed. It has been shown that the theoretical simulations of the responses correlate well with the experimental data.

The NH3 thermal annealing and decoupled plasma nitridation (DPN) processes are compared for the equivalent oxide thickness (EOT) scaling of atomic-layer-deposited hafnium zirconate (HfZrO2) gate dielectric. Detailed physical, optical, and electrical characteristics of nitrided HfZrO2 (HfZrON) film are reported. It is found that DPN can yield a thinner SiOx interfacial layer (IL) (about 0.12 nm more in terms of EOT scaling)and a more densified HfZrO2 layer compared to those obtained using NH3 thermal annealing at a 16% nitrogen dose. NH3 thermal nitridation causes a large nitrogen distribution tail at the SiOx IL/Si substrate interface and increases leakage current, which suppresses EOT scalability.

This paper developed the software testing factory-cloud testing platform (STF-CTP) to address the software compatible issues in various smart devices. Software developers who only require uploading the application under test (AUT) and test script can test plenty of smart devices in STF-CTP. The challenge for the cloud test platform is how to optimize the resource and increase the performance in the limited resource. This paper proposed a new scheduling mechanism and a new process of the system operation which is based on the OpenStack platform. We decrease about 40% memory usage of OpenStack server, increase 3% to 10% Android device usage of STF-CTP, enhance about 80% test job throughput and reduces about 40% test job average waiting time.

This study proposes a single-stage light-emitting diode (LED) tube lamp driver with input-current shaping for T8/T10-type fluorescent lamp replacements. The proposed AC-DC LED driver integrates a dual-boost converter with coupled inductors and a half-bridge series-resonant converter with a bridge rectifier into a single-stage power conversion topology. This paper presents the operational principles and design considerations for one T8-type 18 W-rated LED tube lamp with line input voltages ranging from 100 V rms to 120 V rms. Experimental results for the prototype driver show that the highest power factor (PF = 0.988), lowest input current total harmonic distortion (THD = 7.22%), and highest circuit efficiency (η = 92.42%) are obtained at an input voltage of 120 V. Hence, the proposed driver is feasible for use in energy-efficient indoor lighting applications.
