The paper aims at researching the collaboration business process model of logistics supply chain system based on EPC. The data mining technology is applied for the proposed model in this paper. The problem that core members of supply chain face will be how to choose better partners in order to improve product quality, service and performance, thus to enhance customer satisfaction, so research on suppliers as the source of the supply chain has great significance for the enterprise. Meanwhile, a lot of data and information is accumulated by supply chain operation, then how to get unknown or hidden knowledge from these vast amounts of data and information through BI (Business Intelligence) and DM (Data Mining) techniques so as to guide the optimization and implementation of supply chain will play a very important role. Therefore, this dissertation combine the real business of supply chain management system to research the relevant data mining methods and techniques, to solve the supplier classification problem in order to support supply chain operation effectively.

The bulk commodity, different with the retail goods, has a uniqueness in the location selection, the chosen of transportation program and the decision objectives. How to make optimal decisions in the facility location, requirement distribution, shipping methods and the route selection and establish an effective distribution system to reduce the cost has become a burning issue for the e-commerce logistics, which is worthy to be deeply and systematically solved. In this paper, Logistics warehousing center model based on ideal point method and linear weighted method is proposed to solve this problem. In addition, we have designed principles of the ideal point method and linear weighted method to solve the proposed model because of its complexity. Finally, we have solved numerous examples to compare the results of lingo and Matlab, we use Matlab and lingo just to check the result and to illustrate the numerical example, we can find from the result, the multi-objective model increases logistics costs and improves the efficiency of distribution time.

The work addresses the issues of the ever-expanding demand of wide free spectral range (FSR) compatible integrated optic passive devices used in commercial communication systems like dense wavelength division multiplexing and a host of other applications. FSR expansion has been achieved by using the Vernier principle. The analysis has been carried out using Mason's rule and the delay line signal processing approach. Performances of two resonator structures made of silicon-on-insulator-based waveguides with two different effective refractive indices, viz., 1.7 and 2.811, have been compared. The maximum FSR of 3527 THz with finesse of 4409 has been obtained from the first architecture. © 2012 Optical Society of America.

Although electronic health records (EHRs) have been implemented in many hospitals and healthcare providers benefit from their effective and efficient data processing, their evaluation from nurses has received little attention. This project aimed to assess the adoption and barriers to the use of an EHR system by nurses at three governmental hospitals implementing the same EHR software and functionalities in Eastern Province, Saudi Arabia. The study was a cross-sectional, paper-based questionnaire study. SPSS version 20 was used for data entry and analysis, and descriptive statistics were calculated. The study found underutilization of almost all functionalities among all hospitals and no utilization of any communication tools with patients. In addition, there were no instances of "allowing patients to use the Internet to access parts of their health records." The most frequently cited barrier among all hospitals was "loss of access to medical records transiently if computer crashes or power fails" (88.6 percent). This was followed by "lack of continuous training/ support from information technology staff in hospital" (85.9 percent), "additional time required for data entry" (84.9 percent), and "system hanging up problem" (83.8 percent). Complexity of technology (81.6 percent) and lack of system customizability (81.1 percent) were also frequently reported problems. The formation of an EHR committee to discuss problems with the system in Saudi hospitals is recommended.

A waveguide-based wide free-spectral-range (FSR) triple ring resonator (TRR) as an optical filter has been investigated in this article. The transmittance of the TRR is presented in Z-domain. The delay line signal processing approach and Mason's gain formula have been used to develop the transmittance of the TRR. The TRR in the article is capable of providing an FSR up to 605 GHz with lower crosstalk limited within -10 dB. Another efficacious scheme of TRR with much wider FSR of 1029 GHz and with reduced unit delay length is presented in the article. Here also crosstalk, as well as resonance loss, remains within reasonable limits. The FSRs obtained using the present TRR architectures in this work are until now reported as maximum for a corresponding class of optical ring resonators. The issues of group delay and dispersion, two important parameters associated with high frequency optical communication have been addressed in this article. © 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).

Modern supply chains focus on an ultimate consumer satisfaction and often require essential dynamic reconfiguration. Manufacturing companies constitute important central nodes in supply chains, where almost all physical flows are concentrated. Postponement is the operating concept, which aims at delaying activities until a customer's order has been received. The growth of interest in the postponement concept partially results from the increased demand for customized products. Data for the analysis has been collected through the survey carried out by researchers in several countries. The main research instrument used for this research was a questionnaire developed by the Global Manufacturing Research Group (GMRG). The conclusions formulated on the basis of data analysis proved that market and demand characteristics do not seem to be important for the choice between postponement and speculation strategy. The research showed that assembly postponement depends mostly on managerial decisions about the goals of company and the level of acceptance of an assembly postponement strategy on the market. Full postponement strategy is dictated mainly by the level of product customization and capacities of manufacturing and logistics systems. Production postponement has to be accepted on the market and should be associated with excellent forecasting techniques. © 2010 Elsevier B.V. All rights reserved.

In the present work, electromagnetic field confinement in a subwavelength waveguide structure is obtained using concepts of quantum mechanics and uncertainty principle. Semi-macroscopic considerations of field interaction at the dielectric interfaces are used in this work. The modal field profile in the subwavelength waveguide is obtained by considering the photon as a particle in the waveguide having finite probability of tunneling. Thus, uncertainty of position is assigned to it. The momentum uncertainty is calculated from position uncertainty. Schrdinger wave equation for the photon is written by incorporating position-momentum uncertainty. The equation is solved and the field distribution in the waveguide is obtained. The field distribution and power confinement is compared with conventional waveguide theory. They were found in good agreement with each other. © 2012 Copyright Taylor and Francis Group, LLC.

Microring resonator (MRR) based optical devices using Silicon-on-insulator (SOI) waveguides are enabling technology. Using multiple microring resonators, very wide free spectral range (FSR) can be obtained. Design and analysis of optical filter using five microring resonators, i.e., pentuple microresonator has been carried out with the help of delay line signal processing and Mason's gain formula. An FSR of approximately 4007THz and a crosstalk of -60 dB have been obtained. The group delay and resulting dispersion characteristics have been investigated. FSR expansion has been achieved using Vernier principle. These CMOS-compatible integrated optic devices are capable of accommodating possibly a large number of WDM channels. © 2015 IEEE.

Stresses for the elastic-plastic transition and fully plastic state have been derived for a thin rotating disc with rigid shaft at different temperatures and results have been discussed and depicted graphically. It has been observed that at room temperature rotating disc made of compressible material and of smaller radii ratio yields at the internal surface at a higher angular speed as compared to rotating disc made of incompressible material. With the introduction of thermal effect rotating disc yields at the outer surface at a lesser angular speed as compared to rotating disc at room temperature. The circumferential stress is maximum at the outer surface of the rotating disc with further increases with the increase in temperature. It means that angular speed of the rotating disc is less than that of the temperature-loaded disc in the fully plastic case.
