CFD Analysis of a Centrifugal Compressor Impeller and Volute (1999)

In this study, centrifugal compressor performance was predicted using CFD. Three-dimensional time-averaged impeller and volute simulations were performed using a Navier–Stokes code. The presented performance prediction method has been divided into three phases. Firstly, the impeller was calculated with a vaneless diffuser. That gives inlet boundary conditions for the volute analysis and the pressure ratio at the diffuser exit. Next, the volute analysis was performed and a static pressure recovery coefficient obtained. Finally, that result was combined with the pressure ratio prediction from the impeller analysis, and the overall compressor performance thus obtained.
Comportement plastique de matrices époxydes et de composites en relation avec leur structure moléculaire (1990)

Le comportement plastique de reseaux epoxydes modeles et de composites unidirectionnels a fibres de carbone est etudie en relation avec la structure moleculaire. La plasticite est apprehendee en termes de germination et de propagation de microzones cisaillees. Dans le stade de propagation, les mobilites moleculaires associees a la transition beta et la mobilite des noeuds de reticulation controlent la plasticite. Le role primordial du durcisseur est ainsi mis en evidence. L'etude du stade de germination indique que la reticulation et la rigidite des chaines controlent l'aptitude a la deformation non elastique. La mesure directe du taux de durcissement structural permet de caracteriser la nucleation de la plasticite au sein des materiaux composites. Il en ressort que les rearrangements microstructuraux locaux caracteristiques des reseaux reticules gouvernent l'evolution avec la temperature du comportement plastique de facon identique dans le composite et dans la resine pure.

Design of 4×4 microstrip Quasi-Yagi beam-steering antenna array operation at 3.5GHz for future 5G vehicle applications (2017)

In this paper, a novel design of 4×4 microstrip Quasi-Yagi beam-steering antenna array operation at 3.5GHz for future 5G vehicle applications is proposed. This array consists of sixteen element antennas with dimension of 374×374×1.15mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> , which exhibits good bandwidth (impedance bandwidth of single antenna element about 440MHz for S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> less than -10dB at the center frequency of 3.5GHz) and high gain (for single antenna about 7dBi and for antenna array about 5.8~8.76dBi). The beam-steering characteristics in the operation band can nearly achieve omni-directional radiation.
Postnatal dietary supplementation with either gangliosides or choline: Effects on spatial short-term memory in artificially-reared rats (2007)

This study addressed the hypothesis that dietary supplementation with either gangliosides or choline during the brain growth spurt would enhance short-term spatial memory. Male Long-Evans rats were reared artificially from postnatal days (PD) 5-18 and were fed diets containing either (i) choline chloride 1250 mg/l (CHL), (ii) choline chloride 250 mg/l and GD3 24 mg/l (GNG) or (iii) choline chloride 250 mg/l (STD). A fourth group (SCK) was reared normally. Rats were weaned onto AIN 93G diet and on PD 35 were trained on a cued delayed- matching-to-place version of the Morris water maze. All groups learned to swim to the beacon that indicated the platform position on the first trial; similarly, on the second un-cued trial, the distance swam to reach the platform decreased to the same extent in all groups over the five days of training. The groups also responded in the same way to an increase in delay between the first and second trial from 1 min to 1 h, showing an increase in the distance swam, accompanied by a decrease in the number of direct swims to the platform. Thus, all rats were equally proficient at using spatial short-term memory, regardless of the choline or ganglioside content of the preweaning diet.
Modular engineering of conventional plants (2022)

Although it is expected that 25 % of future process plants in chemical and pharmaceutical industries will be built utilizing modular fabrication and automation by 2030, the question arises how to leverage the potential of modular automation for the remaining process plants. This contribution will show a concept of a modular engineering approach for conventional process plants, based on Module Type Package (MTP) and so-called Function Modules. The concept has been validated with an oil and gas use case which has been reviewed in several workshops.
AnomalousZdependence of a magnetic dipole transition in the Ti I isoelectronic sequence (1996)

In isoelectronic sequences, transition wavelengths ordinarily move rapidly to shorter wavelengths as Z increases. However, it has been predicted that a particular sequence of magnetic dipole (M1) transition wavelengths for the Ti-like ions, ${\mathrm{Xe}}^{+32}$ through ${\mathrm{U}}^{+70}$, remain relatively constant in the 320--400-nm range. In the present paper we extend the experimental identifications of the Ti-like M1 transitions from Ba and Xe to Nd (${\mathrm{Nd}}^{+38}$) and Gd (${\mathrm{Gd}}^{+42}$) to verify this behavior. Using the newly acquired wavelengths to adjust atomic parameters, we have also calculated improved wavelengths for all such M1 transitions between Xe (Z=54) and Os (Z=76). \textcopyright{} 1996 The American Physical Society.
MIMO Performance of Realistic UE Antennas in LTE Scenarios at 750 MHz (2011)

Multiple-input-multiple-output (MIMO) is a technique to achieve high data rates in mobile communication networks. Simulations are performed at both the antenna level and Long-Term Evolution (LTE) system level to assess the performance of realistic handheld devices with dual antennas at 750 MHz. It is shown that MIMO works very well and gives substantial performance gain in user devices with a quarter-wavelength antenna separation.
Stochastic last-mile delivery problems with time constraints (2015)

&lt;p&gt;When a package is shipped, the customer often requires the delivery to be made within a particular time window or by a deadline. However, meeting such time requirements is difficult, and delivery companies may not always know ahead of time which customers will need a delivery. In this thesis, we present models and solution approaches for two stochastic last-mile delivery problems in which customers have delivery time constraints and customer presence is known in advance only according to a probability distribution. Our solutions can help reduce the operational costs of delivery while improving customer service.&lt;/p&gt; &lt;p&gt;The first problem is the probabilistic traveling salesman problem with time windows (PTSPTW). In the PTSPTW, customers have both a time window and a probability of needing a delivery on any given day. The objective is to find a pre-planned route with an expected minimum cost. We present computational results that characterize the PTSPTW solutions. We provide insights for practitioners on when solving the PTSPTW is beneficial compared to solving the deterministic analogue of the problem.&lt;/p&gt; &lt;p&gt;The second problem is the same-day delivery problem (SDDP). The SDDP is a dynamic and stochastic pick-up and delivery problem. In the SDDP, customers make delivery requests throughout the day and vehicles are dispatched from a warehouse or brick and mortar store to serve the requests. Associated with each request is a request deadline or time window. In order to make better-informed decisions, our solution approach incorporates information about future requests into routing decisions by using a sample scenario planning approach with a consensus function. We also introduce an analytical result that identifies when it is beneficial for vehicles to wait at the depot. We present a wide range of computational experiments that demonstrate the value of our approaches.&lt;/p&gt;
Turbo-Estimation for CPM Over Frequency-Selective Fast Fading Channels (2019)

The benefits of continuous phase modulation (CPM), namely high power and spectral efficiencies, are often overshadowed by the high complexity that comes along with the nonlinearity of the modulation format. We tackle the problem of detection of a quaternary CPM signal in a frequency-selective fast fading channel. In particular, we derive a joint detector-equalizer using the Laurent principal pulse approximation. To handle time-selectivity, we adopt the well-known turbo-estimation approach. However, it turns out that classical turbo-estimation cannot be directly applied, but has to be modified beforehand. With the help of Monte Carlo bit error rate (BER) simulations, we show that using the modified turbo-estimation approach, the receiver is able to track channel variations within a transmit burst under fast fading conditions. This allows for a larger payload-to-overhead ratio. Since joint detection-equalization is practically feasible only for channels with short memory, we also consider a suboptimal approach which decouples detection from equalization.
Dyeing Properties of Reactive Cationic Dyes Containing a Vinyl‐sulphonvl Group on Acrylic Fibre Blends (1979)

The preparation of reactive azo cationic dyes containing a vinylsulphonyl group derived from 2‐aminobenzothiazole and its derivatives is described. Their dyeing properties on blends of acrylic–cellulosic, polyester–cellulosic fibre and on cotton and synthetic fibres are investigated. The relationship between absorption spectra and pH of dye solution is assessed.
On the eigen-decomposition of electromagnetic systems and the frequency dependence of the associated eigenvalues (2005)

The asymptotic waveform evaluation (AWE) technique is a useful way to minimize repeated electromagnetic system computations for multiple frequencies, dramatically reducing wideband solution times. In the context of AWE, it has already been shown (Y.E. Erdemli et al., 1999) (J. Gong and J.L. Volakis, 1996) that use of the Fade rational function for the modeling of unknowns is a superior choice to the Taylor series expansion, providing a wider bandwidth coverage; owing to its enhanced ability to model pole behavior. This paper discusses a close analog to the Fade rational function developed from the eigenvalues of a given electromagnetic system. For Illustrative purposes, we chose the finite element boundary integral (FE-BI) method to demonstrate the application and utility of AWE expansions based on the eigenvalues of the FE-BI matrix system

Brennstoffe für Brennstoffzellen (1963)

Abstract Die Entwicklung der Wasserstoff‐Sauerstoff‐Brennstoffzellen ist zu einem gewissen Abschluß gekommen. Da der Wasserstoff üblicherweise als hochkomprimiertes Gas in Stahlflaschen verwendet wird, bedeuten das Gewicht der Behälter und auch der Preis des Brennstoffs einen Nachteil für eine allgemeine Anwendung. Man versucht deshalb, andere Zelltypen zu entwickeln, die den Wasserstoff entweder in Generatoren erzeugen oder direkt wasserstoffhaltige Verbindungen, z. B. Methan verbrennen. Der Stand der Entwicklung sowie die noch bestehenden Probleme werden gezeigt.
Minimal Forbidden Subgraphs of Unimodular Multicommodity Networks (1979)

An integral matrix with independent columns is called unimodular if the greatest common divisor of the determinants of its maximum-rank square submatrices is one. An integral matrix A (not necessarily having independent columns) is defined to be unimodular if every basis of A has that property. It is known that this is so if and only if the extreme points of the set of nonnegative vectors x satisfying Ax = b are integral for all integral vectors b. Here the constraint matrix of a k-commodity network flow problem is shown to be unimodular if and only if the associated (undirected) graph does not have a subgraph homeomorphic to the following graphs: (i) the complete graph on four nodes, and if k ≥ 3, (ii) a cycle with three additional edges, each a duplicate of a different edge of the cycle, having no node with degree 2 (these graphs have from three to six nodes). The following algorithm checks whether subgraphs of the above type are present. First find the 2-connected subgraphs that contain at least two edges. Then reduce each such subgraph to a graph with fewer nodes and arcs. The forbidden subgraphs are not present if and only if the algorithm reduces each 2-connected subgraph to a cycle with two edges. When this is not possible, a forbidden subgraph is produced. Suitable implementation of the algorithm results in O(n) complexity, where n is the number of edges of the original graph.
A token-based authorized file-sharing protocol for BitTorrent-like P2P systems (2011)

In recent years, more and more people use Internet and with the improvements of communication technology, information-sharing trends has surged over Internet. Bit-Torrent is a well-known P2P application used for distributing large amounts of data and exchange digital content with high efficiently and scalability. Unfortunately, many users do not get authorization but transmit files through Bit-Torrent illegally. The piracy problems become a very serious issue because the digital contents can be copied and redistributed easily through P2P network without license owners' authorized. For this reason, digital rights management (DRM) is considered as a general preventive measure to avoid copyright infringement. However, a conventional DRM system implementation on distributed P2P network would be quite difficult. Therefore, we propose an efficient DRM model on P2P network that to prevent violation of copyrights for digital content owners and to provide more attractive motivation for users.

Biological Activity of a Growth Factor for Ovarian Cells (1974)

The biological activity of a protein growth factor is described. This factor was isolated from bovine pituitary tissue, and its activity was tested on cells of rat ovarian origin. Activity was assayed as growth-promoting potential measured by cell counts and is concentrationdependent. Similar growth stimulation was not produced by several cyclic nucleotides tested, neither was there crossreactivity between this growth factor and a chemically similar one produced by rat liver cells.

Epidemic algorithms for replicated database maintenance (1988)

When a database is replicated at many sites, maintaining mutual consistency among the sites in the face of updates is a significant problem. This paper describes several randomized algorithms for distributing updates and driving the replicas toward consistency. The algorithms are very simple and require few guarantees from the underlying communication system, yet they ensure that the effect of every update is eventually reflected in all replicas. The cost and performance of the algorithms are tuned by choosing appropriate distributions in the randomization step. The algorithms are closely analogous to epidemics, and the epidemiology literature aids in understanding their behavior. One of the algorithms has been implemented in the Clearinghouse servers of the Xerox Corporate Internet. solving long-standing problems of high traffic and database inconsistency.
phydms : software for phylogenetic analyses informed by deep mutational scanning (2017)

It has recently become possible to experimentally measure the effects of all amino-acid point mutations to proteins using deep mutational scanning. These experimental measurements can inform site-specific phylogenetic substitution models of gene evolution in nature. Here we describe software that efficiently performs analyses with such substitution models. This software, phydms, can be used to compare the results of deep mutational scanning experiments to the selection on genes in nature. Given a phylogenetic tree topology inferred with another program, phydms enables rigorous comparison of how well different experiments on the same gene capture actual natural selection. It also enables re-scaling of deep mutational scanning data to account for differences in the stringency of selection in the lab and nature. Finally, phydms can identify sites that are evolving differently in nature than expected from experiments in the lab. As data from deep mutational scanning experiments become increasingly widespread, phydms will facilitate quantitative comparison of the experimental results to the actual selection pressures shaping evolution in nature.
Multiplicity of glutamic acid decarboxylases (GAD) in vertebrates: molecular phylogeny and evidence for a new GAD paralog (1999)

The evolution of chordate glutamic acid decarboxylase (GAD; EC 4.1.1.15), a key enzyme in the central nervous system synthesizing the neurotransmitter gamma-amino-butyric acid (GABA) from glutamate, was studied. Prior to this study, molecular data of GAD had been restricted to mammals, which express two distinct forms, GAD65 and GAD67. These are the products of separate genes and probably are derived from a common ancestral GAD following gene duplication at some point during vertebrate evolution. To enable a comprehensive phylogenetic analysis, molecular information of GAD forms in other vertebrate classes was essential. By reverse transcriptase-polymerase chain reaction (RT-PCR), partial nucleotide sequences of GAD were cloned from brains of zebra finch (Taeniopygia guttata), turtle (Trachemys scripta), goldfish (Carassius auratus), zebrafish (Danio rerio), and armoured grenadier (Coryphaenoides (Nematonurus) armatus, a deep-sea fish), and from the cerebral ganglion plus neural gland of Ciona intestinalis, a protochordate. Whereas GAD65 and GAD67 homologs were expressed in birds, reptiles, and fish, only a single GAD cDNA with equal similarities to both vertebrate GAD forms was found in the protochordate. This indicates that the duplication of the vertebrate GAD gene occurred between 400 and 560 million years ago. For both GAD65 and GAD67, the generated phylogenetic tree followed the general tree topology for the major vertebrate classes. In turtle, an alternative spliced form of GAD65, putatively encoding a truncated, nonactive GAD, was found. Furthermore, a third GAD form, which is equally divergent from both GAD65 and GAD67, is expressed in C. (N.) armatus. This third form might have originated from an ancient genome duplication specific to modern ray-finned fishes.
The batch-to-batch non-reproducibility of the compression ability of lactose. Reasons and detection. (1993)

Il a souvent ete observe que les proprietes technologiques du lactose peuvent varier selon les lots, parfois provenant du meme fabricant, pour une matiere premiere de meme qualite, de meme granulometrie et de meme denomination. Le but de ce travail est d'essayer de comprendre les raisons de cette variabilite. Le lactose est un α monohydrate. Il est extrait du lait par recristallisation apres concentration. De ce fait, plusieurs causes de variabilite sont possibles: impuretes provenant du lait, traces de β lactose et degre d'evaporation laissant plus ou moins d'eau
Abiotic stress signal transduction in plants: Molecular and genetic perspectives (2001)

Low temperature, drought and salinity are major adverse environmental factors that limit plant productivity. Understanding the mechanisms by which plants perceive and transduce these stress signals to initiate adaptive responses is essential for engineering stress-tolerant crop plants. Molecular and biochemical studies suggest that abiotic stress signaling in plants involves receptor-coupled phosphorelay, phosphoinositol-induced Ca2+ changes, mitogen-activated protein kinase cascades and transcriptional activation of stress-responsive genes. In addition, protein posttranslational modifications and adapter or scaffold-mediated protein-protein interactions are also important in abiotic stress signal transduction. Most of these signaling modules, however, have not been genetically established to function in plant abiotic stress signal transduction. To overcome the scarcity of abiotic stress-specific phenotypes for conventional genetic screens, molecular genetic analysis using stress-responsive promoter-driven reporter is suggested as an alternative approach to genetically dissect abiotic stress signaling networks in plants.
The facets of the entrepreneur: identifying entrepreneurial potential (2004)

People who start new businesses vary in the degree of entrepreneurial talent and temperament they possess. The same is true of strategic leaders and intrapreneurs inside large organisations, where entrepreneurial people are required to champion the change agenda in dynamic and turbulent environments. These issues can be explored in the context of six key entrepreneur character themes, or natural and instinctive behaviours. Techniques help, but alone they cannot compensate for missing characteristics. Without the important entrepreneur characteristics, survival and growth rates are lower. This paper outlines a new framework for identifying entrepreneurs and describes the research programme through which the model has been validated.
