[Comparative humidity measurements in semiclosed and semiopen systems with the additional use of artificial noses]. (1987)

The administration of dry anesthetic gases for ventilation lasting more than 1 h leads to morphological changes of the tracheobronchial epithelium that may cause postoperative pulmonary complications. Therefore, additional humidification is suggested for ventilation during anesthesia, particularly when using semiopen breathing systems. Recommendations concerning the use of semiclosed systems are controversial: previous studies have shown sufficient humidification on the one hand, and insufficient water content in the inspired air on the other hand. In this study, comparative humidity measurements in a semiopen and a semiclosed system were carried out during anesthesia and mechanical ventilation. We particularly wanted to find out whether placement of the fresh gas inlet into the circle before or behind the soda lime canister influences the humidity of the inspired gas. In addition, we tested three types of "heat and moisture exchanges"--Engström "Edith", Siemens "Servo Humidifier", and Portex "Humid Vent". A total of 58 patients between 23 and 78 years of age were studied. They were divided into three groups. Group I: In 10 patients comparative humidity measurements were carried out using both a semiopen and a semiclosed system. Group II: The time course of water saturation during a 3-h period was determined in 10 patients ventilated with a semiopen and 8 patients ventilated with a semiclosed circle system. Group III: In 20 patients we tested the effect of "heat and moisture exchangers". All patients were intubated and ventilated with the Spiromat 656 and the Circle System 8 (Drger) that made ventilation in both a semiclosed and a semiopen system possible. The humidity measurements were carried out using a psychometric method.(ABSTRACT TRUNCATED AT 250 WORDS)

Industrial IEEE 802.3 networks with short delivery time for urgent messages (1988)

Two solutions are investigated for introducing priority mechanisms in the CSMA/CD (carrier-sense multiple access with collision detection) protocol defined in the IEEE 802.3 standard to provide short delivery times for urgent messages even when the overall traffic on the channel is heavy. Thus the CSMA/CD protocol, attractive because of its low cost, also becomes suitable for a class of industrial control applications. The proposed schemes can easily be implemented by using already-available chips and boards because they are based on the dynamic management of a transmission parameter, the slot time; this feature is already present in the standard IEEE 802.3, where it is set statically when the network is configured. The first configuration considered implements a message priority scheme, where the priority level for the station can be updated at each new message transmission, varying the slot time according to the message characteristics. The second configuration introduces a fixed-station-priority mechanism which allows each node in the network to be assigned to a specific priority class.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

How to significantly improve the spectral efficiency of linear modulations through time-frequency packing and advanced processing (2012)

We recently investigated the spectral efficiency, achievable with a symbol-by-symbol receiver, for linear modulations employing time-frequency packing. In this paper, we will investigate the improvements that can be obtained by increasing the receiver complexity. In the numerical results, we will mainly concentrate on time packing (an extension of the so called faster-than-Nyquist signaling technique) and on (i) receivers based on linear processing plus symbol-by-symbol detection or (ii) receivers based on a more sophisticated trellis processing with constrained complexity. Finally, the potential advantage of the proposed signalling scheme when combined with conventional low-density parity-check (LDPC) coding of the DVB-S2 air interface will be presented.
Exploring the limits of conventional small-scale CHO fed-batch for accelerated on demand monoclonal antibody production (2021)

In the field of therapeutic antibody production, diversification of fed-batch strategies is flourishing in response to the market demand. All manufacturing approaches tend to follow the generally accepted dogma of increasing titer since it directly increases manufacturing output. While titer is influenced by the biomass (expressed as IVCD), the culture time and the cell-specific productivity (q<sub>P</sub>), we changed independently each of these parameters to tune our process strategy towards adapted solutions to individual manufacturing needs. To do so, we worked separately on the increase of the IVCD as high seeding fed-batch capacity. Yet, as intensified fed-batch may not always be possible due to limited facility operational mode, we also separately increased the q<sub>P</sub> with the addition of specific media additives. Both strategies improved titer by 100% in 14 days relative to the standard fed-batch process with moderate and acceptable changes in product quality attributes. Since intensified fed-batch could rival the cell-specific productivity of a conventional fed-batch, we developed novel hybrid strategies to either allow for acceptable seeding densities without compromising productivity, or alternatively, to push the productivity the furthest in order to reduce timelines.

Reputation in self-organized communication systems and beyond (2006)

Efficiently handling reputation is important in dealing with free-riding, malicious attacks and random failures in self-organized communication systems. At the same time, work in this context is often found to be relevant in many other disciplines, in particular the social sciences. A number of distributed reputation systems have been proposed and analyzed, although research has not been very coherent. In this paper, for the first time, we provide an overview of the state-of-the-art in the various computer science communities as well as the social sciences. In particular, we present results obtained from our mathematical model devised to investigate the impact of liars on their peers' reputation about a subject. We find that liars have no impact unless their number exceeds a certain threshold (phase transition behaviour). We give precise formulae and quantify the impact, thereby providing insight into fundamental questions in social networks as well as facilitating performance evaluation and optimization of distributed reputation systems in communication networks. We conclude by suggesting fundamental directions for future research into reputation.
An analytic model for tool trajectory error in 5-axis machining (2008)

Purpose: This paper proposes an analytical method of evaluating the maximum error by modeling the exact tool path when the tool traverses singular region in five-axis machining. Design/methodology/approach: It is known that the Numerical Control (NC) data obtained from the inverse kinematic transformation can generate singular positions, which have incoherent movements on the rotary axes. Such movements cause unexpected errors and abrupt operations, resulting in scoring on the machined surface. To resolve this problem, previous methods have calculated several tool positions during a singular operation, using inverse kinematic equations to predict tool trajectory and approximate the maximum error. This type of numerical approach, configuring the tool trajectory, requires a lot of computational time to obtain a sufficient number of tool positions in the singular region. We have derived an analytical equation for the tool trajectory in the singular area by modeling the tool operation, by considering linear and nonlinear parts that are a general form of the tool trajectory in the singular area and that are suitable for all types of five-axis machine tools. In addition, evaluation of the maximum tool-path error shows high accuracy, using our analytical model. Findings: : In this study, we have separated the linear components of the tool trajectory from the nonlinear ones, to propose a tool trajectory model that is applicable to any kind of 5-axis machine. We have also proposed a method to calculate the maximum deviation error based on the proposed tool trajectory model. Practical implications: The algorithms proposed in this work can be used for evaluating NC data and for linearization of NC data with singularity. Originality/value: Our algorithm can be used to modify NC data, making the operation smoother and reducing any errors within tolerance.

The characteristics of large area processing plasmas (2003)

In order to improve production efficiency, large-diameter wafer substrates (300-mm diameter) and large-area glass substrates (from 400 cm/sup 2/ to 1 m/sup 2/) have been adopted recently. As a result, the development of large and high-density plasma source has become essential. To investigate the discharge phenomenon in the chamber that consists of embedded antenna coil in the rectangular system (1020 /spl times/830 /spl times/437 mm), we have developed a two-dimensional fluid simulation model. In order to check our model, the results from our simulation have been compared with available experimental data. The comparison is generally in a good agreement with experiments. Depending on the current direction and powered method, the distribution of plasma parameters has many differences. In our simulation with a chamber larger than is usually used in other experiments, we examine three effects: the distance between antenna coils, structure in the chamber, and the depth of the chamber. The parameters, which affect nonuniformity, electron temperature, and others, can be explained in a manner similar to the inductively coupled plasma source with a cylindrical chamber. Our simulation results confirm that the embedded antenna coil system with a suitable environment can be extended by many antenna coils as a large-area plasma source.

Epidemiology of Carbapenem-Resistant Klebsiella pneumoniae in a Network of Long-Term Acute Care Hospitals (2016)

Nearly 25% of K. pneumoniae clinical isolates in a US network of LTACHs were CRKP. Expansion of national surveillance efforts and improved communication among LTACHs and acute care hospitals will be critical for reducing the continued emergence of CRKP across the healthcare continuum.
Polar nephelometer for atmospheric particulate studies (1980)

A unique polar nephelometer was designed and constructed for the measurement of atmospheric particulate characteristics. The nephelometer produces visible light from a self-contained laser to irradiate an air sample drawn into the instrument. The light scattered from the particulates and molecules in the sample is detected as a function of scattering angle for each of four different incident light polarizations. These measurements are used to determine the particulate scattering matrix which is a function of the size, shape, and index of refraction of the particles. The region of sensitivity for the measurements corresponds to the size range of particles that strongly affects visible radiative transfer in the atmosphere, which is the primary application for the derived information.
Hemoglobinopathies in the Los Angeles Area (1983)

Several surveys of abnormal hemoglobins in Los Angeles and in the Southwestern United States have been published in recent years (1–4), and the frequencies of the well known abnormal hemoglobins, such as Hbs S, C, and E, have been reported in this area; some rarer mutants and several new variants have also been described. In one study, an unselected population was studied by screening cord blood specimens in a large municipal hospital, and frequencies of Hbs S, C, and D were determined in various ethnic groups (3).
Thermal Properties and Phase Transition Behavior of KNN-AN Piezoelectric Ceramics (2011)

Abstract Piezoelectric thermal stability is often a critical issue for many piezoelectric materials in practical applications. Lead-free piezoelectric ceramics, (1−x)K0.5Na0.5NbO3– xAgNbO3 (KNN-AN, with x = 0–0.35) have been synthesized by a conventional solid state sintering method. The temperature dependence of the dielectric, ferroelectric and piezoelectric properties of lead-free piezoelectric ceramics was investigated. The piezoelectric properties exhibit a very good thermal stability up to high temperature, which is a significant improvement from other KNN-based piezoceramics.

Avaliação técnica e econômica da colheita florestal com Feller-Buncher (2011)

O Feller-buncher constitui uma das máquinas mais utilizadas na colheita florestal, cuja principal função é realizar a derrubada e o enleiramento das árvores. Objetivou-se, neste trabalho, avaliar técnica e economicamente a derrubada de árvores inteiras com o Feller-buncher, em duas posições distintas de tombamento destas, em florestas de eucalipto (posição 1 = derrubada a 45º e, posição 2 = derrubada a 90º). A análise técnica englobou um estudo de tempos e movimentos e de produtividade. A análise econômica contemplou os parâmetros custo operacional, custo de produção e rendimento energético. Concluiu-se que não houve diferença entre as posições 1 e 2 de derrubada quanto ao tempo para realizar o tombamento das árvores, tendo sido o corte o elemento parcial que consumiu a maior parte do tempo do ciclo operacional, com aproximadamente 66% deste, nas duas posições de derrubada. A produtividade por hora efetiva de trabalho do Feller-buncher foi de, aproximadamente, 347 árvores (48,8 m³/he), o custo operacional de R$ 195,26, proporcionando um custo de produção da máquina de R$ 3,95/m³e um rendimento energético de 3,8 g/W m³; para ambas as posições de derrubada das árvores. Apesar da similaridade em termos de produtividade e custo das duas posições de derrubada avaliadas, recomenda-se tombar as árvores à 45º, devido à maior facilidade de enleiramento destas, bem como no intuito de beneficiar a operação subsequente (extração).
Viral Infections from Blood Transfusions and Tissue Grafts: Reducing the Risk (2004)

Remarkable progress in achieving a safe blood supply has occurred since the 1980s, when nearly 1% of U.S. blood units contained HIV or hepatitis C virus (HCV). Until 1999, blood screening relied mostly on serologic methods or serum markers for HIV-1 and HCV. Because such tests failed to identify infected donors during the window period before seroconversion, nucleic acid-amplification (NAA) minipool testing was implemented. Tissue grafts, currently used in about 1 million medical procedures annually, can also transmit infectious agents (see Journal Watch …
Improving near real-time anomaly event detection and classification with trend change detection for smart water grid operation management (2022)

To improve the efficiency of Smart Water Grid (SWG) operation, it is of great importance to timely detect and classify anomaly events. Authors have developed a comprehensive solution framework for anomaly detection. However, the framework may detect undesirable false alarms, which will incur wasteful field investigation. Therefore, it is imperative to reduce the number of false alarms for real world SWG operation. In this paper, the anomaly event classification has been improved by an algorithm of trend change detection in two phases including (1) detecting trend change in single sensor, and (2) identifying the effective evaluation time window by correlating the flow anomaly trend period and pressure anomaly trend periods to filter the detected events. A real case study has been conducted to demonstrate the application of the proposed algorithm; the number of false alarms is reduced by as much as 31% without compromising the detection accuracy.
Modeling flow, heat and mass transfer in a porous biomass plug - when used in an electrically heated tobacco system (2016)

Heating porous biomass samples is utilized in many industries for drying or extracting Volatile Organic Compounds (VOC) from the biomass. The heating may trigger physical and chemical processes within the material, such as release of VOC, thermal degradation and evaporation. For most practical applications, it is important to have control of the complex processes occurring during heating to generate stable and controllable release of VOC. This is the case of an Electrically Heated Tobacco System (EHTS) delivering the released VOC to consumers by inhalation. In this work, Computational Fluid Dynamics (CFD) was used to model the physical and chemical processes numerically to demonstrate the operating conditions that the tobacco plug was exposed to during product use and to highlight the product functioning upon heating. The simulated temperature in the porous biomass plug was compared to experimental data obtained by thermocouples inserted into the biomass plug. In addition, the simulated amount of VOC exiting the product was compared to experimentally measured data for glycerol and nicotine. The close match between numerical and experimental results indicate that most relevant physical and chemical processes are understood and were accounted for in the numerical model. The tobacco plug was also shown to remain below the temperature controlled heater temperature during use.
Lubrication Oil Degradation Trajectory Prognosis with ARIMA and Bayesian Models (2019)

In order to predict lubrication oil degradation, it is important to analyze the degradation trajectory in detail. Lubrication oil degradation is influenced by numerous factors e.g. oil replenishment, oil filtering, operating conditions and system maintenance etc. that need to be considered for accurate degradation prediction. Degradation trajectory prediction provides the remaining useful life (RUL). Whereas the analysis of degradation influencing factors with their roles in prediction provides opportunity to extend or control the RUL. This paper analyzes the lubrication oil degradation trajectory under the influence of oil replenishment. We consider a data correction strategy and prognosis for lubrication oil degradation using the auto-regressive integrated moving-average (ARIMA) and Bayesian dynamic linear model (BDLM) approaches. Degradation data is generated using model-based simulations. The prediction models are then tested on the simulated degradation data set. This study exemplifies the method to find the underlying degradation model considering and identifying the degradation influencing factors.
WebScout: support for revisitation of Web pages within a navigation session (2003)

WebScout is a system that creates a personal archive of Web pages seen by the user and a rich record of the user's navigation, including various types of user and system generated annotations. We explore how this rich archive can be used to provide support for user navigation, in particular, for revisitation of pages within a navigation session. We describe the WebScout SessionNavigator feature that enhances the current browser functionality by providing both sequential and graph representation of the user navigation. It introduces the concept of a WebTrail which designates a sequence of navigation steps, started by a particular event, such as search, or explicit specification of a URL by typing into the address bar, or executing a link from a bookmark list. We present details of a user study that explores how users perceive and remember their navigation on the Web.
