Peak-load shaving in smart homes via online scheduling (2011)

This paper addresses the problem of load-shaving in Smart Homes in view of improving energy efficiency in Smart Grids. An architecture of home power management systems, allowing the separation of domestic power load control from grid dynamics, is introduced. In this framework, the operation of appliances is modeled as a finite state machine which enables the implementation of online scheduling borrowed from the techniques developed in real-time computing systems. A scheduling algorithm is developed for peak-load shaving and the simulation results confirm the effectiveness and the efficiency of the proposed approach.
Experiences with a Permanently Installed Seismic Monitoring Array at the CO2 Storage Site at Ketzin (Germany). - A Status Overview - (2013)

Since July 2008, CO2 is injected into a saline aquifer near the town of Ketzin in Germany. For monitoring the CO2- migration close to the injection well, TNO installed a fixed 2D seismic array of 120 meters length in 2009, with 3- component geophones at the surface, 4-component receivers at 50 meters depth and a central vertical array of 4- component receivers. This specific test acquisition set-up was and is being used both for the recording of high-quality active time-lapse seismic data as well as for continuous passive seismic data recording. The latter gave rise to the identification of a large number of surface noise related events and some very weak events possibly originating from the deeper subsurface. The active seismic data acquisition consisted of a conventional repeat survey after 2 years using an accelerated weight drop source, as well as a test with a prototype semi-permanent source located at the site during a period of 3 weeks in which CO2 injection was stopped. In both cases subtle changes at the reservoir level have been observed, though the limitations of the experimental lay-out make it difficult to come up with firm conclusions in terms of CO2 induced pressure and saturation changes. Further analysis of the data is ongoing work.
Hydrolytic stability of some uncured epoxy resins (1981)

Abstract The hydrolytic stability of triglycidyl(4‐aminophenol) (ERL 0500), tetraglycidyl(methylenedianiline) (MY720), and a number of model compounds has been investigated. It has been shown that at 60°C and 96% relative humidity undiluted N ‐glycidyl aromatic amine‐based epoxy resins readily undergo hydrolysis followed by homopolymerization. Impurities in the resin may significantly accelerate the rate of reaction. The effect of the consequent loss of epoxide on the performance of an adhesive based on ERL 0500 has been studied. The high‐temperature tensile‐shear strength of Joints was markedly reduced when the adhesive was aged, before cure, for 24 hr at 60°C and 96% relative humidity. Some implications of these findings for aerospace applications of epoxy compounds are discussed.

Formats de détection de produits d'amplification PCR : application à la mise en évidence du provirus VIH-1 (1994)

La reaction de polymerisation en chaine (polymerase chain reaction ou pcr) est devenue un outil indispensable dans les laboratoires de biologie moleculaire. Certaines applications notamment en diagnostic medical, exigent une specificite et une sensibilite maximale. Les formats employes doivent etre simples et compatibles avec une utilisation en routine de cette technique. Dans ce travail, nous presentons la mise au point d'un test diagnostic (amplicis ) base sur la pcr. Ce procede, qui permet une amelioration de la specificite et de la sensibilite du processus d'amplification, exploite les possibilites de modifications chimiques des oligonucleotides de synthese, pour aboutir a des systemes de revelation specifiques isotopiques ou colorimetriques, sur phase solide (tubes). La revelation colorimetrique est amelioree, grace a l'utilisation d'un conjugue anticorps monoclonal-enzyme. Amplicis isotopique est ensuite adapte a la mise en evidence du provirus du vih 1 chez des patients seropositifs. Pour cette application, nous proposons une simplification des protocoles de preparation des echantillons sanguins. Une validation de tout le processus est realisee chez des enfants nes de mere seropositive ; les resultats sont compares avec les techniques classiques de mise en evidence de l'infection chez les nouveaux-nes. Nous proposons par ailleurs un format nouveau pour la quantification, a travers une approche chimique de la mesure differentielle de deux signaux sur phase solide. Ce concept est applique a la quantification de l'oncogene c-myc dans des lignees cellulaires par co-amplification de la cible et d'un standard interne. Toutes ces etudes sont realisees avec un objectif de standardisation des essais, pour une diffusion en toute securite de ce type de tests
ACRV derived transportation system (1992)

Alternate means for manned transportation to low earth orbit are being considered by NASA to complement and eventually replace the Space Shuttle. One method of achieving two-way transportation is through the modification of Assured Crew Return Vehicle (ACRV). The ACRV is a manned transportation system designed to bring home Space Station Freedom crews in the event of an emergency or Shuttle standdown. The ACRV is launched in the Space Shuttle-payload bay and is designed for earth return from low earth orbit. A study was performed that addressed the modification of an ACRV into a two-way manned transportation system. The Station Crew Return Alternate Module (SCRAM) configuration was chosen as the reference ACRV vehicle. This paper will discuss the requirements and ground rules used in the study as well as the design modifications made to the ACRV.
A phosphorylated subpopulation of the histone variant macroH2A1 is excluded from the inactive X chromosome and enriched during mitosis (2008)

Histone variants play an important role in numerous biological processes through changes in nucleosome structure and stability and possibly through mechanisms influenced by posttranslational modifications unique to a histone variant. The family of histone H2A variants includes members such as H2A.Z, the DNA damage-associated H2A.X, macroH2A (mH2A), and H2ABbd (Barr body-deficient). Here, we have undertaken the challenge to decipher the posttranslational modification-mediated "histone code" of mH2A, a variant generally associated with certain forms of condensed chromatin such as the inactive X chromosome in female mammals. By using female human cells as a source of mH2A, endogenous mH2A was purified and analyzed by mass spectrometry. Although mH2A is in low abundance compared with conventional histones, we identified a phosphorylation site, S137ph, which resides within the "hinge" region of mH2A. This lysine-rich hinge is an approximately 30-aa stretch between the H2A and macro domains, proposed to bind nucleic acids. A specific antibody to S137ph was raised; by using this reagent, S137 phosphorylation was found to be present in both male and female cells and on both splice variants of the mH2A1 gene. Although mH2A is generally enriched on the inactive X chromosome in female cells, mH2AS137ph is excluded from this heterochromatic structure. Thus, a phosphorylated subpopulation of mH2A appears to play a unique role in chromatin regulation beyond X inactivation. We provide evidence that S137ph is enriched in mitosis, suggestive of a role in the regulation of mH2A posttranslational modifications throughout the cell cycle.
Isolating the Effect of Torsional Defects on Mobility and Band Gap in Conjugated Polymers (2008)

Conjugated polymers represent a promising class of organic semiconductors with potential applications in a variety of molecular devices. Poly(3-alkylthiophene)s, in particular, are garnering interest due to their large charge carrier mobility and band gap in the visible region of the spectrum. Defects play a pivotal role in determining the performance of polymer electronics, and yet the function of specific types of defects is still largely unknown. Density functional theory calculations of alkyl-substituted oligothiophenes are used to isolate the effect of static inter-ring torsion defects on key parameters such as electronic coupling between rings and band gap. Results have potential implications both for the fundamental understanding of intramolecular charge transport and for improving processing in organic devices.

Separate Error-Free Transmission of Eight Channels at 10 Gb/s Using Comb Generation in a Quantum-Dash-Based Mode-Locked Laser (2009)

We report on comb generation at 1.55 mum using a mode-locked quantum-dash-based laser. A flat optical spectrum with a ~10-nm width consisting of eight 100-GHz-spaced channels is demonstrated. Separate error-free transmission of each channel is achieved at 10 Gb/s over 50-km-long single-mode fiber. Compared to an ideal external cavity continuous-wave laser, a penalty of only 1.5 dB is measured for each filtered channel. This is attributed to the higher relative intensity noise level of a filtered mode.
Electrochemical Reduction of CO2at Cu Nanocluster / (1010) ZnO Electrodes (2013)

The electrochemical reduction of CO2 in aqueous bicarbonate electrolytes is studied using Cu nanoclusters on single crystal 1010 ZnO electrodes. Cu is known to generate methane as a primary product in electrochemical reduction reactions while the combination of Cu and ZnO produces methanol in gas-phase synthesis reactions. In reduction experiments at -1.4 V versus Ag/AgCl, gas phase products include hydrogen, carbon monoxide, methane and ethylene and liquid phase products include methanol, ethanol, formate, methyl formate and trace levels of propanol. faradaic efficiencies of Cu/ZnO electrodes are similar relative to Cu electrodes with the exception of alcohols where selectivity is improved by an order or magnitude. In-situ FTIR analysis shows several liquid-phase products along with methoxy and formate adsorbates. The nature of the improved alcohol selectivity and intermediates are considered relative to proposed mechanisms and results from this work. © 2013 The Electrochemical Society.

Using Wearable Sensors for Real-Time Recognition Tasks in Games of Martial Arts - An Initial Experiment (2006)

Beside their stunning graphics, modern entertainment systems feature ever-higher levels of immersive user-interaction. Today, this is mostly achieved by virtual (VR) and augmented reality (AK) setups. On top of these, we envision to add ambient intelligence and context awareness to gaming applications in general and games of martial arts in particular. To this end, we conducted an initial experiment with inexpensive body-worn gyroscopes and acceleration sensors for the chum kiu motion sequence in wing tsun (a popular form of kung fu). The resulting data confirm the feasibility of our vision. Fine-tuned adaptations of various thresholding and pattern-matching techniques known from the fields of computational intelligence and signal processing should suffice to automate the analysis and recognition of important wing tsun movements in real time. Moreover, the data also seem to allow for the possibility of automatically distinguishing between certain levels of expertise and quality in executing the movements.
Lateral resolution improvement of laser-scanning imaging for nano defects detection (2014)

Abstract Demand for higher efficiency in the semiconductor manufacturing industry is continually increasing. In particular, nano defects measurement on patterned or bare Si semiconductor wafer surfaces is an important quality control factor for realizing high productivity and reliability of semiconductor device fabrication. Optical methods and electron beam methods are conventionally used for the inspection of semiconductor wafers. Because they are nondestructive and suitable for high-throughput inspection, optical methods are preferable to electron beam methods such as scanning electron microscopy, transmission electron microscopy, and so on. However, optical methods generally have an essential disadvantage about lateral spatial resolution than electron beam methods, because of the diffraction limit depending on the optical wavelength. In this research, we aim to develop a novel laser-scanning imaging method that can be applied to nano-/micro manufacturing processes such as semiconductor wafer surface inspection to allow lateral spatial super-resolution imaging with resolution beyond the diffraction limit. In our proposed method, instead of detecting the light intensity value from the beam spot on the inspection surface, the light intensity distribution, which is formed with infinity corrected optical system, coming from the beam spot on the inspection surface is detected. In addition, nano scale shifts in the beam spot are applied for laser spot scanning using a conventional laser-scanning method in which the spots are shifted at about a 100 nm pitch. By detecting multiple light intensity distributions due to the nano scale shifts, a super-resolution image reconstruction with resolution beyond the diffraction limit can be expected. In order to verify the feasibility of the proposed method, several numerical simulations were carried out.
Annealing effect on Cu2ZnSn(S,Se)4 solar cell with Zn1–xMgxO buffer layer (2015)

(Zn,Mg)O buffer layer has attracted attention with the potential to control the conduction‐band offset (CBO) at the interface between the buffer layer and the Cu 2 ZnSn(S,Se) 4 (CZTSSe) absorber, where the (Zn,Mg)O buffer layer is deposited by sputtering. The bandgap energy ( E g ) of (Zn,Mg)O layers is tunable from 3.3 to 7.7 eV by changing the Mg/(Zn + Mg) ratio. Thus, short‐wavelength response of solar cells with a (Zn,Mg)O buffer layer is higher than that with a CdS buffer layer. Nevertheless, the solar‐cell performances with a (Zn,Mg)O buffer layer is significantly lower than that with a CdS buffer layer. The low performances are attributed to the sputtering damage on the CZTSSe absorber. To recover sputtering damage, the annealing treatment was conducted on CZTSSe solar cells. However, after the annealing treatment, the performances of CZTSSe solar cells decreased. Photoluminescence (PL) spectra of the CZTSSe absorbers without and with the annealing treatment were measured to evaluate the (Zn,Mg)O/CZTSSe junction quality. From the results, the PL intensity presents a slight variation, while the E g of the CZTSSe absorbers decreases. Thus, the defects near the space‐charge region activate. Consequently, the decrease of the sputtering damage was not confirmed by the annealing treatment. Therefore, a damage‐free method for the deposition of (Zn,Mg)O layer is necessary.
On the Performance of Network Coding in Multi-Resolution Wireless Video Streaming (2010)

Scalable video can be used to provide video streaming reliably to an heterogeneous set of receivers with different subscription levels. However, the performance of such schemes can be highly affected by scheduling constraints and unreliable feedback. Network coding, on the other hand, has been shown to reduce scheduling and prioritization problems and to perform well in wireless scenarios with perfect feedback. Motivated by this observation, we implement and analyze a system architecture for network coding-based multiresolution video streaming in a wireless environment. In contrast to existing work, we take into account realistic feedback, where the control packets are sent over the same unreliable channel as data packets, and compare it to the case of perfect feedback, where the server has perfect knowledge of the state of the buffer at every receiver. We provide an evaluation of the system via simulation and show that even in highly volatile environments, a network coding-based scheme with limited and unreliable feedback can achieve a good performance.
Selective Hydrodeoxygenation of Biomass‐Derived Oxygenates to Unsaturated Hydrocarbons using Molybdenum Carbide Catalysts (2013)

Which cleavage do you prefer? With a combination of density functional theory (DFT) calculations, surface science studies, and reactor evaluations, Mo(2)C is identified as a highly selective HDO catalyst to selectively convert biomass-derived oxygenates to unsaturated hydrocarbons through selective C-O bond scissions without C-C bond cleavage. This provides high-value HDO products for utilization as feedstocks for chemicals and fuels; this also reduces the overall consumption of H2 .
Development of Fluorinated Benzothiadiazole as a Structural Unit for a Polymer Solar Cell of 7 % Efficiency (2011)

High-powered polymer: Fluorinated benzothiadiazole was incorporated into a polymer that was used in a high-performance solar cell. The model polymer 2 has decreased HOMO and LUMO energy levels and a similar band gap when compared with its nonfluorinated analogue 1. A bulk heterojunction device derived from 1 demonstrated a high power conversion efficiency of 7.2 % (5.0 % for 1).
Effect of High Salt Concentration on Ion Clustering and Transport in Polymer Solid Electrolytes: a Molecular Dynamics Study of PEO-LiTFSI (2018)

The model and analysis methods developed in this work are generally applicable to any polymer electrolyte/cation-anion combination, but we focus on the currently most prominent polymer electrolyte material system: poly(ethylene) oxide/Li- bis(trifluoromethane) sulfonamide (PEO + LiTFSI). The obtained results are surprising and challenge the conventional understanding of ionic transport in polymer electrolytes: the investigation of a technologically relevant salt concentration range (1 - 4 M) revealed the central role of the anion in coordinating and hindering Li ion movement. Our results provide insights into correlated ion dynamics, at the same time enabling rational design of better PEO-based electrolytes. In particular, we report the following novel observations. 1. Strong binding of the Li cation with the polymer competes with significant correlation of the cation with the salt anion. 2. The appearance of cation-anion clusters, especially at high concentration. 3. The asymmetry in the composition (and therefore charge) of such clusters; specifically, we find the tendency for clusters to have a higher number of anions than cations.
Reconfigurable equalization for 10-Gb/sec serial data links in a 0.18-μm CMOS technology (2006)

The objective of the proposed research is to realize a 10-Gb/sec serial data link over band-limited channels, such as backplanes, multi-mode fiber, and copper-based cables that were originally designed for data rates less than 1Gb/sec. This is achieved using electrical equalization implemented in an integrated circuit (IC). To successfully compensate for various band-limited channels at the targeted data rate with a single equalizer IC, a reconfigurable equalizer topology is proposed. In order to realize the proposed goal, various channels are characterized of their forward transmission frequency response. Based on the measured channel data, system simulations are performed to identify the required specifications for IC implementation. This provides information such as optimal number of taps, fractionally-spaced tap delay, and tap coefficients for the proposed IC. With the obtained system requirements, IC building blocks are designed and fabricated in a 0.18- and #956;m CMOS technology. The fully-integrated reconfigurable CMOS equalizer provides a single-chip solution for compensating various band-limited channels. This enables 10-Gb/sec serial data transmission achieving signal integrity beyond their designed specifications.
Response From Silberstein and Winner (2003)

In response to the letter from Adelman et al regarding the article “Migraine Preventive Medication Reduces Resource Utilization,” we would like to make the following points: Cost was calculated without including the cost of preventive drugs since the aggregate database included all preventive drugs. Our data show what the calculated reduction in cost would be if a preventive program were started. These were not patients referred to a tertiary headache center. All simply had consulted a physician in order to receive a triptan. It is logical to assume that life-style changes and behavioral therapy would have been initiated along with acute treatment and before the prescription of preventive treatment. Our conclusions are valid within the constraints of an aggregate database.
Efficiency enhancement of grating couplers for single mode polymer waveguides through high index coatings (2014)

Abstract- High-index coatings on top of surface gratings strongly enhance the grating coupling strength in low-index contrast waveguide systems. This opens up new fields of applications for grating couplers such as coupling into single-mode polymer waveguides.
Subjective and Objective Estimation of Physical Activities on the Lower Extremities for Inpatient Staff Nurses and Their Lower Extremity Musculoskeletal Discomfort (2017)

Registered nurses have a higher incidence rate of work-related musculoskeletal disorders (MSDs) compared with the overall rate for MSDs in the U.S. Attention has been on back pain in nurses, but the lower extremities are also a frequent site of discomfort in nurses, though only a few studies have reported on this problem, investigations of risk factors are limited, and reports of successful interventions are primarily anecdotal. Studies in other populations have identified prolonged time on one’s feet as a risk factor for various lower extremity problems. This study aims to determine the prevalence of hospital inpatient staff nurses’ lower extremity discomfort and to subjectively and objectively quantify lower extremity physical activities exposure during work, specifically walking, standing, and sitting, and examine any interaction with type of unit or shift, in order to begin to describe the physical loading of the lower extremities in this type of nursing work.
Purification and Characterization of an Esterase Hydrolyzing Monoalkyl Phthalates from Micrococcus sp. YGJ1 (2005)

An esterase that specifically hydrolyzes medium-chain (C(3)-C(5)) monoalkyl phthalates was purified from phthalate-grown Micrococcus sp. YGJ1. The enzyme activity was split into two fractions by hydrophobic chromatography on Phenyl Sepharose, and the enzymes were purified to homogeneity from each fraction. The purified enzymes showed similar properties with respect to molecular mass (60 kDa), subunit molecular mass (27 kDa), N-terminal amino acid sequence, optimal pH (about 7.5), temperature-dependence, substrate specificity, and inhibitor susceptibility. The enzymes showed no activity toward various dialkyl phthalates or aliphatic carboxyl esters. 2-Mercaptoethanol effectively protected the enzymes from spontaneous inactivation. Diethylpyrocarbonate, p-chloromercuribenzoate, Hg(2+), and Cu(2+) strongly inhibited the enzymes, while phenylmethylsulfonyl fluoride produced weak inhibition, and various metal chelating reagents were ineffective. These findings show that the enzymes bear a close resemblance to the putative phthalate ester hydrolase (PehA) of Arthrobacter keyseri 12B.
