Traditional planar lightwave circuits fabricated from lithographically-patterned waveguides in glasses, semi-conductors or polymers cannot accommodate the wide range of materials required by typical optical devices. In addition, such waveguides are nearly always defined in the material surface and thus can support only a limited density of interconnects and suffer poor performance at waveguide ...

This paper investigates the impact of the irregular microgeometry of polyurethane acoustic foam on the macroscopic acoustic behavior predicted by a unit-cell model. Two semi-empirical unit-cell models coupled to a rigorous sensitivity analysis technique are used for this purpose. In these models, the porous material is idealized as a packing of a periodic unit-cell (PUC) representative of the d...

BACKGROUND Understanding the three-dimensional (3-D) micro-architecture of lung tissue can provide insights into the pathology of lung disease. Micro computed tomography (µCT) has previously been used to elucidate lung 3D histology and morphometry in fixed samples that have been stained with contrast agents or air inflated and dried. However, non-destructive microstructural 3D imaging of formal...

INTRODUCTION One may regard the first epoch in the structural studies of naturally occurring carotenoids as terminated with the authoritative monograph by Karrer and Jucker1 in 1948. In the classical period structural determinations of carotenoids, derived mainly from plant sources, were carried out by semi-micro methods by means of chemical degradation. Useful methods such as various types of ...

Handover management is one of the most critical issues that mobility management protocols are concerned with. This process becomes even more critical in the case of Micro-mobility where the Mobile host is expected to encounter frequent handovers. Several IP micro-mobility protocols have been proposed to enhance the performance of Mobile IP in an environment with frequent handoffs. In this paper...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

This paper presents a data gathering for Advanced Process Control (APC) in FA (Factory Automation). It is important that the gathered data in FA to control all the processing, to be a predictive maintenance of equipments and manage products. We gathered the entire data of all in FA through Equipment Engineering System (EES) and analyzed that to control a processing, predict the next processing ...

This study analyzes the decentralization process of Leprosy control actions for Family Health Strategy units in the cities of the Almenara micro-region, in the state of Minas Gerais, Brazil. This qualitative research, based on the concept "Technological Organization of Work", was carried out in nine municipalities. Semi-structured interviews and document research were used for data collection. ...

Data mining systems semi-automatically discover knowledge by mining a large volume of data, but discovered knowledge is not always novel to users. We discuss a discovered rule filtering method to filter rules discovered by a data mining system into ones that are novel to the user by using information retrieval results from the Internet. We have two methods; the micro view and the macro view met...

The existing colonoscope requires a dexterous skill of surgeon to perform the insertion in entire colon. The procedure is painful to the patient. Therefore, biomedical and robotic researchers are developing a locomotive colonoscope that can travel safely in colon In this paper, we describe a new design and concept of semi-autonomous micro robot for colonoscopy. The micro robot comprises the act...
