AU - Grant, E. AU - ghosh AU - Seyam, Abdel-Fattah AU - Lee, G. AB - The production of protective garments is a complex process which generally involves nonwoven and tailored fabric structures. This paper presents an approach that integrates robotics with meltblown technology in addressing some of the problems associated with this garment production. In particular, a rule base 3D control is developed and an evaluation of the quality control of the 3D fabric structures formed using this system is performed using a basis-weight function analysis to measure uniformity. Melt-blowing of a polypropylene mixture was conducted by directly forming 3D fabrics on a mannequin mold. The results obtained show that when a constant-velocity control strategy is used during the fiber spraying phase, the basis-weight uniformity had a 16% coefficient of variation (CV). However, when a rule-based control strategy is applied using a displacement transducer for feedback and a set of fiber application rules for control, the CV is reduced to 11%. Thus the proposed system achieves the goal of improving uniformity of shaped fabric structures.

Here we summarize the results obtained by exercising the models, with the main emphasis placed on whether or not the upstream operations of spinning, fabric production, and dyeing and finishing were capable of meeting Quick Response (QR) requirements for response time and service levels. In carrying out this work, questions arose about the kind of information systems required to link the various entities in the supply chain, alternative scheduling procedures, the possibility of interactive management-information systems that would allow rapid responses to the concerns of senior managers, and user-friendly means for technology transfer. We have also begun to explore the use of fuzzy mathematics to model the uncertainty and vagueness inherent in most supply-chain decision-making. Work on these topics is discussed here in Part II.

The models are scaled to represent a supply chain designed to feed a garment-manufacturing operation involving four or five plants, i.e. part of each plant's output is ‘dedicated’ while simultaneously providing yarns and fabrics to the industry at large. Each of the sector models is unique because of the very different types of processing technology employed. The models are linked by means of streams of fabric orders from the manufacturing plants that make a range of garment types requiring many different fabrics for Basic (year-round sales), Seasonal (two or three seasons per year), and Fashion (shelf lives of 8–12 weeks) goods in a broad range of colors. In addition to each plant's product ranges and order sizes and frequencies, particular attention is paid to the machine-scheduling algorithms, although the models are deliberately kept at a ‘high’ as opposed to a ‘shop-floor’ level. The purpose of this modeling is to allow senior management to answer broad questions about the plants' ability to operate in a Quick Response environment. The various model outputs reflect this, having a heavy emphasis on on-time shipments, back-order levels, and service levels. In Part II of the series, we shall present the QR-related operating results to date, a description of a master-scheduling procedure to orchestrate the operations of the supply chain, ideas on an improved scheduling method, and an account of the construction of neural-network decision surface models as a decision support tool. We also overview ongoing efforts in technology transfer and in using ‘fuzzy’ mathematics to model the vagueness and uncertainty inherent in the supply- chain decision-making environment. The research effort of which this is a part is ongoing. We present these results in the hope of encouraging others to help carry the investigations forward.

The observed STM images were interpreted by calculating partial electron density plots of the surface, and for naphthalene-adsorbed surfaces, by carrying out Monte Carlo simulations for the adsorption of a naphthalene molecule on the surface. The STM images recorded for the pristine (001) surface correspond to the cation layer of (TMTSF)2PF6, and each circular bright spot of the molecular-resolution STM images represents the three hydrogen atoms of the most protruding methyl group of a TMTSF molecule on the (001) surface. Naphthalene molecules adsorbed on this surface form a pseudomorphic (1 × 1) overlayer structure with respect to the underlying substrate. The naphthalene overlayer shows mechanical stability against etching by the scanning tip. An identical overlayer structure of naphthalene was obtained from several different preparation methods. On the cation-layer (001) surface naphthalene is adsorbed on each “four-methyl-step” defined by four methyl groups of two adjacent TMTSF molecules within each TMTSF stack.

Our analysis indicates that the spin exchange interactions of the nanotube are not described by three-legged ladders, but by six mutually intersecting helical chains, and the magnetic properties of the nanotube in the low temperature region can be well approximated by those of a single helical chain. Each helical chain is described by four antiferromagnetc spin exchange parameters J1–J4 with the repeat sequence [–J2–J1–J3–J4–]∞, where |J1|>|J2|>|J3|>|J4|. The nanotube is expected to have a spin gap.

The anisotropy of the spin exchange interactions in the HPO phase is well explained by the delta e-delta e0 values. For the APO phase, the reported crystal structure does not provide accurate enough delta e-delta e0 values to conclude unambiguously which of the V1-V2 and V3-V4 chains has a larger spin gap and which of the bridged and edge-sharing spin dimers has a stronger spin exchange interaction in the V1-V2 and V3-V4 chains. The APM phase is predicted to exhibit essentially two spin gaps, with a large spin gap for the V8-V5-V7-V6 chain and a very small one for the V4-V2-V3-V1 chain.

A probabilistic model is developed to predict the different CV values obtained from the different instruments, and the results are compared with experimental values.

The relative stabilities of the three known and three hypothetical IrTe2 polymorphs were discussed on the basis of tight binding electronic band structure calculations. m-IrTe2 exhibits structural features of both CdI2- and pyrite-type IrTe2 phases and is expected to be nearly as stable as that of the CdI2-type IrTe2. The hypothetical IrS2- and ramsdellite-type IrTe2 phases are predicted to be more stable than the CdI2-type IrTe2.

Supercritical fluid dyeing technology has the potential to accomplish this objective in many commercial textile applications around the world, both at present and in the future around the world. Increased interest in this technology has made a fundamental understanding of thermophysical (equilibrium solubility) and transport (kinetics) properties of such fluids and fluid mixtures necessary. Supercritical carbon dioxide (SC-CO2) is one of the most environmentally acceptable solvents in use today, and textile processes using it have many advantages when compared to conventional aqueous processes.1-4 Positive environmental effects range from drastically reduced water consumption to eliminating hazardous industrial effluent. Furthermore, economic benefits include increased productivity and energy savings. Successfully commercializing supercritical fluid CO2 processing will improve the economics of dyeing and other textile chemical processes by eliminating water usage and wastewater discharges and increasing productivity by reducing processing times as well as required chemicals and auxiliaries and reducing energy consumption and air emissions. As a result, SC-CO2 processing will be more rapid, more economical, and more environmentally friendly.1 DA - 2000/12// PY - 2000/12// DO - 10.1021/ie0002475 VL - 39 IS - 12 SP - 4806-4812 SN - 0888-5885 ER - TY - JOUR TI - Ligand influences on the structures of molybdenum oxide networks AU - Hagrman, P.

K2Mo9S11 and K1.8Mo9S11 are metallic and exhibit resistivity anomalies below ∼115 and ∼80 K, respectively. The origin of these anomalies is explained in terms of their Fermi surfaces. Our study indicates that the resistivity anomalies of these compounds are caused by the partial nesting of their two-dimensional Fermi surfaces and that both K2Mo9S11 and Rb2Mo9S11 should exhibit a charge density wave phenomenon.

In both quantum oscillations with two different frequencies Fα = 634 T and Fβ = 4245 T are observed. These results confirm the calculated FS, which consists of one-dimensional and two-dimensional parts separated by a small energy gap. It is shown that the temperature and field dependence of the oscillation amplitudes can be well described by standard Lifshitz-Kosevich theory considering the magnetic breakdown by the so-called coupled network model. Beatings of the oscillation amplitudes are observed by field-dependent dHvA and SdH experiments. They can be explained by a slightly warped FS showing that this material represents a quasi–two-dimensional electronic system. The observed beating nodes in the dHvA and SdH signals appear at different magnetic fields. This fact is discussed in terms of additional scattering mechanisms.

T2 - MRS Internet Journal of Nitride Semiconductor Research AB - An ultraviolet-specific (320-365 nm) digital camera based on a 128×128 array of backside-illuminated GaN/AlGaN p-i-n photodiodes has been successfully developed. The diode structure consists of a base n-type layer of AlGaN (~23% Al) followed by undoped and then p-type GaN layers deposited by metal organic vapor phase epitaxy. Double-side polished sapphire wafers serve as transparent substrates. Standard photolithographic, etching, and metallization procedures were employed to fabricate the devices. The fully-processed photodiode array was hybridized to a silicon readout integrated circuit (ROIC) using In bump bonds for electrical contact. The UV camera was operated at room temperature at frame rates ranging from 15 to 240 Hz. A variety of UV scenes were successfully recorded with this configuration.

Optical path difference profiles, calculated based on the proposed orthotropic structure, are in reasonable qualitative agreement with interference microscope data. Quantitatively, however, the orthotropic structure is only partially developed based on published values of the principle refractive indices. Furthermore, the degree to which this structure is developed varies with distance from the fiber axis in some fibers' types.
