Evaluation of adhesion of continuous fiber–epoxy composite/aluminum laminates (2004)

Abstract Continuous fiber composite/metal laminates (FMLs) offer significant improvements over currently available composite materials for aircraft structures due to their excellent fatigue endurance and low density. Glass fiber–epoxy composite laminae and aluminum foil (GLARE) are commonly used to obtain these hybrid laminates. In this work, FMLs were produced by treating the aluminum foil to promote adhesion bonding by two methods: sulphuric chromic acid etching (SCAE) and chromic acid anodization (CAA). The surface treatments were evaluated by contact angle, roughness and scanning electron microscopy techniques. In order to compare different families of fiber composite/metal laminates, carbon fiber and glass fiber fabrics were used as reinforcements for the hybrid laminates. The adhesion of the hybrid laminates was evaluated by scanning electron microscopy (SEM) and three-point bending test. CAA resulted in better wetting properties. The interlaminar shear strength results for both carbon fiber-epoxy/metal and glass fiber-epoxy metal, were close to the interlaminar shear strength results found in the literature (approx. 40.0 MPa).

HTIMIT and LLHDB: speech corpora for the study of handset transducer effects (2002)

This paper describes two corpora collected at Lincoln Laboratory for the study of handset transducer effects on the speech signal: the handset TIMIT (HTIMIT) corpus and the Lincoln Laboratory Handset Database (LLHDB). The goal of these corpora are to minimize all confounding factors and produce speech predominately differing only in handset transducer effects. The speech is recorded directly from a telephone unit in a sound-booth using prompted text and extemporaneous photograph descriptions. The two corpora allow comparison of speech collected from a person speaking into a handset (LLHDB) versus speech played through a loudspeaker into a handset (HTIMIT). A comparison of analysis and results between the two corpora addresses the realism of artificially creating handset degraded speech by playing recorded speech through the handsets. The corpora are designed primarily for speaker recognition experimentation (in terms of amount of speech and level of transcription), but since both speaker and speech recognition systems operate on the same acoustic features affected by the handset, the knowledge gleaned is directly transferable to speech recognizers. Initial speaker identification performance on these corpora are presented. In addition, the application of HTIMIT in developing a handset detector that was successfully used on a Switchboard speaker verification task is described.

A single-fiber bi-directional WDM self-healing ring network with bi-directional OADM for metro-access applications (2007)

We propose and demonstrate a single-fiber bidirectional wavelength division multiplexing self-healing ring network for metro-access applications. By incorporating a simple bi-directional optical add-drop multiplexer at each network node as well as employing our proposed alternate-path switching scheme, the bi-directional traffic can be restored promptly under single fiber failure in the ring network. All the protection switching is performed at the hub only, thus the operation, administration and management cost can be easily optimized

Design and performance of a main memory hardware data compressor (2002)

In this paper we show that hardware main memory data compression is both feasible and worthwhile. We demonstrate that paging due to insufficient memory resources can reduce system performance several fold, and argue that hardware memory compression can eliminate this paging hence providing a substantial performance improvement. We describe the design and implementation of a novel compression method, the X-Match algorithm, which is efficient at compressing small blocks of data and suitable for high-speed hardware implementation. Our experimental investigation shows that on average the X-Match algorithm doubles the memory capacity for commonly used Unix applications. Furthermore, the substantial impact such memory compression has on overall system performance is demonstrated.
Processing and properties of 400 series PM stainless steels (1991)

Although the majority of PM stainless steel parts are fabricated from austenitic alloys (300 Series), there are applications where martensitic or ferritic alloys (400 Series) may be used to advantage. Often this advantage is simply economic, 400 Series alloys do not generally contain nickel unlike 300 Series alloys; thus cost savings can be realized if reduced corrosion resistance can be tolerated. Properties may also dictate the choice, such as the higher strength attainable in the heat-treatable martensitic grades. John Reinshagen and John Witsberger review the more popular of the 400 Series PM alloys including the properties that can be expected in finished parts.
1H-1,4-benzothiazines. New cyclic sulphonium ylides (1982)

Five derivatives of the 1H-1,4-benzothiazine ring system (6) have been prepared by cyclodehydration of the sulphoxides (7) with trifluoroacetic anhydride. The derivative (6a) was also prepared by methylation of 2,3-dihydro-2,2-dimethyl-10H-phenothiazin-4(1H)-one (11a). 1H and 13C N.m.r. spectra of the compounds indicate that they can be regarded as stabilised sulphonium ylides, the substituents about the sulphur being in a non-planar arrangement. When heated in hydrochloric acid the ylides are demethylated and give the corresponding 4H-1,4-benzothiazines.
Identification of human postural dynamics (1988)

Human postural dynamics was investigated for six healthy subjects using a force platform recording body sway induced by vibrators attached to the calf muscles. The model of body mechanics adopted was that of an inverted pendulum, the dynamics of postural control being assumed to be reflected in the stabilizing forces exerted on the platform by the feet as a result of complex muscular activity subject to state feedback of body sway and position. The approach to signal processing has been that of parametric identification of a transfer function representing the stabilized inverted pendulum. Posture control was quantified in three variables: swiftness, stiffness, and damping. It is shown that the identification fulfils ordinary statistical validation criteria, and it is conjectured that the state feedback parameters identified are suitable for use in assessing ability to maintain posture.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Analysis of affect expressed through the evolving language of online communication (2007)

In this paper, we focus on affect recognition from text in order to facilitate sensitive and expressive communication in computer-mediated environments. Our model for analyzing affect conveyed by text is tailored to handle the style and specifics of informal online conversations. The motivation behind our approach is to improve social interactivity and emotional expressiveness of real-time messaging.In order to estimate affect in text, our model processes symbolic cues, such as emoticons, detects and transforms abbreviations, and employs natural language processing techniques for word/phrase/sentence-level analysis, e.g. by considering relations among words in a sentence. As a result of the analysis, text can be categorized into emotional states and communicative functions. A designed graphical representation of a user (avatar) displays emotions and social behaviour driven by text and performs natural idle movements. The proposed system shows promising results on affect recognition in real examples of online conversation.
An experimental study on the performance of mixed-flow-type conical walled annular diffusers. (1988)

Experiments have been performed systematically to investigate the performance and flow characteristics for a wide range of mixed-flow-type conical walled annular diffusers. The configuration of this type of diffusers consists of a circular inlet cross-sectional portion and conically diverging inner and outer walls having the same cone angle or different angles. All diffusers were tested in low-speed air flow with the inlet flow condition that the velocity profile is uniform in the core region except for a thin boundary layer on the wall. Systematic data on pressure recovery coefficients are presented comprehensively on the performance chart together with optimum geometry lines of diffusers both at constant diffuser length and at constant diverging area ratio. The performance chart and locations of the optima obtained for this type of diffuser are more similar to those reported previously for simple conical diffusers without inner walls than those for conical walled annular diffusers that consist of annular inlet and annular diverging portions.

NEMO5: A Parallel Multiscale Nanoelectronics Modeling Tool (2011)

The development of a new nanoelectronics modeling tool, NEMO5, is reported. The tool computes strain, phonon spectra, electronic band structure, charge density, charge current, and other properties of nanoelectronic devices. The modular layout enables a mix and match of physical models with different length scales and varying numerical complexity. NEMO5 features multilevel parallelization and is based on open-source packages. Its versatility is demonstrated with selected application examples: a multimillion-atom strain calculation, bulk electron and phonon band structures, a 1-D Schrödinger-Poisson simulation, a multiphysics simulation of a resonant tunneling diode, and quantum transport through a nanowire transistor.
An improved tone reservation method for PAPR reduction in OFDM systems (2013)

Orthogonal frequency division multiplexing (OFDM) systems often suffer from a high peak-to-average power ratio (PAPR), which is essentially due to the phase shift and superposition in the IFFT process. Tone reservation (TR) is a popular PAR reduction technique that uses a set of reserved tones to generate a peak cancelling signal. The usage of the time domain kernel signal has been proposed for TR. However, so far the methods based on the kernel signal have not produced sufficiently good PAPR reduction performance for the lack of overall optimization considerations. In this paper we propose a new method that utilizes the least squares approximation (LSA) and optimal time domain kernel signal based on variance minimization in order to generate the optimal peak cancelling signal. Simulation results show that the proposed approach has lower complexity and better performance than typical other kernel-based approaches such as clipping control method [14] and fast convergence LSA-TR scheme [15].
Comparison of beam propagation method and rigorous coupled-wave analysis for single and multiplexed volume gratings (1996)

Multiplexed holographic structures have been suggested to provide large capacity and parallel access as three-dimensional storage media. One of the most widely used techniques in the literature for analyzing such structures has been the coupled-wave analysis and its variations. Another approach that is becoming increasingly popular because of the ease with which it can be implemented is the beam propagation method (BPM). The BPM is quantitatively compared with the rigorous coupled-wave analysis for the cases of single and multiplexed gratings. Normal and off-normal incidence as well as TE and TM polarizations are considered for single (slanted and unslanted) and multiplexed gratings. It is shown that the BPM, even in its most rudimentary form, is a powerful and accurate calculational method that is especially suited for analyzing the many multiplexed grating diffraction problem.
Layer-by-Layer-Assembled Microfiltration Membranes for Biomolecule Immobilization and Enzymatic Catalysis (2006)

Multilayer assemblies of polyelectrolytes, for protein immobilization, have been created within the membrane pore domain. This approach was taken for two reasons: (1) the high internal membrane area can potentially increase the amount of immobilized protein, and (2) the use of convective flow allows uniform assembly of layers and eliminates diffusional limitations after immobilization. To build a stable assembly, the first polyelectrolyte layer was covalently attached to the membrane surface and inside the pore walls. Either poly(L-glutamic acid) (PLGA) or poly(L-lysine) (PLL) was used in this step. Subsequent deposition occurs by multiple electrostatic interactions between the adsorbing polyelectrolyte [poly(allylamine) hydrochloride (PAH) or poly(styrenesulfonate) (PSS)] and the oppositely charged layer. Three-layer membranes were created: PLL-PSS-PAH or PLGA-PAH-PSS, for an overall positive or negative charge, respectively. The overall charge on both the protein and membrane plays a substantial role in immobilization. When the protein and the membrane are oppositely charged, the amount immobilized and the stability within the polyelectrolyte assembly are significantly higher than for the case when both have similar charges. After protein incorporation in the multilayer assembly, the active site accessibility was comparable to that obtained in the homogeneous phase. This was tested by affinity interaction (avidin-biotin) and by carrying out two reactions (catalyzed by glucose oxidase and alkaline phosphatase). Besides simplicity and versatility, the ease of enzyme regeneration constitutes an additional benefit of this approach.
Temporal Analysis for Adapting Concurrent Applications to Embedded Systems (2008)

Embedded services and applications that interact with the real world often,over time, need to run on different kinds of hardware (low-costmicrocontrollers to powerful multicore processors). It is difficult to writeone program that would work reliably on such a wide range of devices. This isespecially true when the application must be temporally predictable and robust,which is usually be the case since the physical world works in real-time.Thus, any application interacting with such a system, must also work inreal-time.In this paper we introduce a representation of the temporal behavior ofdistributed real-time applications as colored graphs that capture the timingof temporally continuous sections of execution and dependencies between them,creating a partial order. We then introduce a method of extracting the graphfrom existing applications using a combination of analysis techniques. Once thegraph has been created, we introduce a number of graph transformations thatextract ``meaning'' from the graph. The knowledge thus gained, can be utilizedfor scheduling and for adjusting the level of parallelism suitable to the specifichardware, for identifying hot spots, false parallelism, or even candidates foradditional concurrency. The importance of these contributions is evident whenwe see that such graphs can be sequentialized to our partiture model andcan then be used as input for offline, online, or even distributed real-timescheduling. Finally we present results from analysis of a complete TCP/IP stackin addition to smaller test applications which show that our use of differentanalysis models result in a reduction of the complexities of graphs. Animportant outcome is that increasing the expression of concurrency can reducethe level of parallelism required, saving memory on deeply embedded platforms,while keeping the program parallelizable whenever complete serializability isnot required. We also show that applications which were previously consideredto be too complex for characterization of their worst-case behavior are nowanalyzable due to the combination of analysis techniques that we utilize.

Berunda Polypeptides: Multi-Headed Fusion Proteins Promote Subcutaneous Administration of Rapamycin to Breast Cancer <i>In Vivo</i> (2017)

Recombinant Elastin-Like Polypeptides (ELPs) serve as attractive scaffolds for nanoformulations because they can be charge-neutral, water soluble, high molecular weight, monodisperse, biodegradable, and decorated with functional proteins. We recently reported that fusion of the FK-506 binding protein 12 (FKBP) to an ELP nanoparticle (FSI) reduces rapamycin (Rapa) toxicity and enables intravenous (IV) therapy in both a xenograft breast cancer model and a murine autoimmune disease model. Rapa has poor solubility, which leads to variable oral bioavailability or drug precipitation following parenteral administration. While IV administration is routine during chemotherapy, cytostatic molecules like Rapa would require repeat administrations in clinical settings. To optimize FKBP/Rapa for subcutaneous (SC) administration, this manuscript expands upon first-generation FSI nanoparticles (<i>R<sub>h</sub></i> ~ 25 nm) and compares them with two second-generation carriers (FA and FAF) that: i) do not self-assemble; ii) retain a hydrodynamic radius (<i>R<sub>h</sub></i> ~ 7 nm) above the renal filtration cutoff; iii) increase tumor accumulation; and iv) have either one (FA) or two (FAF) drug-binding FKBP domains per ELP protein. <b>Methods:</b> The carriers were compared and evaluated for temperature-concentration phase behavior by UV-Vis spectrophotometry; equilibrium binding and thermodynamics by Isothermal Titration Calorimetry; drug retention and formulation stability by Dialysis and Dynamic Light Scattering; <i>in vitro</i> efficacy using a cell proliferation assay; <i>in vivo</i> efficacy in human MDA-MB-468 orthotopic breast cancer xenografts; downstream target inhibition using western blot; tissue histopathology; and bio-distribution via optical imaging in the orthotopic xenograft mouse model. <b>Results:</b> Named after the two-headed bird in Hindu mythology, the 'Berunda polypeptide' FAF with molecular weight of 97 kDa and particle size, <i>R<sub>h</sub></i> ~ 7 nm demonstrated polypeptide conformation of a soluble hydrated coiled polymer, retained formulation stability for one month post Rapa loading, eliminated toxicity observed with free Rapa after SC administration, suppressed tumor growth, decreased phosphorylation of a downstream target, and increased tumor accumulation in orthotopic breast tumor xenografts. <b>Conclusion:</b> This comprehensive manuscript demonstrates the versatility of recombinant protein-polymers to investigate drug carrier architectures. Furthermore, their facilitation of SC administration of poorly soluble drugs, like Rapa, may enable chronic self-administration in patients.
