P‐65: High Speed‐Addressing Method for Single‐Scan of AC PDP

In this paper, we propose a new structure of the priming discharge panel and the driving schemes in order to achieve high speed address driving. We inserted the priming electrode between two sustain electrode and applied the conventional driving waveform to the scan and sustain electrode, and the extra driving waveform to the priming electrode. Therefore, we realized the stable address with 1μsec data and scan pulse. This address with 1μsec scan pulse means that the single‐scan is possible in XGA or HD‐PDP and then the circuit‐cost can decrease.

On equivalent fire exposure

A B S T R A C T The ability to accurately determine fire resistance requirements is one of the most important aspects of fire safety science. Since fire resistance depends on fire severity, which is a rather ambiguous term, there have been continuous efforts to develop a method for quantifying the term fire severity itself as well as converting it into fire resistance requirements. This paper evaluates two approaches – equivalent temperature and normalised heat load methods, by employing computer fire simulation. It is shown that the latter is a more appropriate quantifier, as it does not rely on an arbitrarily selected reference point and allows for a comparison in an unlike enclosures.
On the use of pressure distributions to model the hydrodynamics of air-cushion vehicles and surface-effect ships

This paper surveys the research conducted on the hydrodynamics of traveling pressure distributions in the period since the first air-cushion-supported marine vehicles appeared. Most of this work has been based on the approximations of potential-flow theory with linearized free-surface conditions, because the level of pressures in these craft is sufficiently low to make these assumptions valid. The specific topics considered include the influence of the planform shape as well as the nature of the pressure fall-off at the edges of the distribution. The effects of canal sides and bottom (as in a towing tank) can also be included. Additionally, arbitrary motion of the pressure (representing a maneuvering vehicle) and fluctuating pressure (modeling the motions in waves) can be studied by the methods detailed here. A number of experiments have also been conducted. These show that there are many instances where the theory can be used to predict the resistance and other important quantities with useful accuracy. I would like to express my appreciation to Mr. Allen Ford of the David Taylor Research Center, Bethesda, for suggesting the preparation of this paper and for his careful review of the manuscript. Mr. Ford has done much to encourage my SES research, including the arrangement of an extended stay at the center during 1977. Much of my research reported in this publication was supported by the Office of Naval Research, the Naval Sea Systems Command (Surface Effect Ships Program Office), and the Australian Research Grants Committee.
Measuring and Interpreting Fabric Low Stress Mechanical and Surface Properties

The concepts of overall handle discussed in Part IV of this series [21] for men's suiting fabrics are explained in this analysis using descriptors called handle attributes. Definitions and English word descriptors are provided for the Japanese primary hand expressions isolated by the Hand Evaluation and Standardisation Committee for these fabric types. Sleekness, fullness, firmness, and drape are isolated as the relatively in dependent descriptors of handle for winter fabrics. Similarly, firmness/hardness, crispness, and fullness also characterize men's suitings. From the results of two inter national studies of handle preferences, judges prefer a sleek, full handle with relatively little stiffness and good drape for winter fabrics. There are strong national preferences for the handle of summer fabrics: there is a common handle assessment for Australian, New Zealand, Indian, U.S., and Hong Kong/Taiwanese panels of judges. There are different, and in some sense opposite, handle preferences for the Japanese and P.R. C. (Chinese) panels, who are mutually consistent. These judges prefer a firm, crisp, hard handle for summer fabrics, while the remaining five national panels exhibit opposite preferences.
A high-power Q-band PHEMT for communication terminal applications

A high-power 0.15 /spl mu/m gate-length pseudomorphic HEMT (PHEMT), developed specifically for high reliability millimeter-wave satellite communication applications, is reported. The device has demonstrated state-of-the-art performance at 44.5 GHz, generating nearly 800 mW output power with 5.8 dB power gain and 25% power-added efficiency, and is designed for operation at low channel temperatures for excellent long-term reliability. The 1800 /spl mu/m gate-width PHEMTs described herein have been produced on 3-inch wafers with high yield and exceptional consistency of high frequency characteristics-for example, five devices sampled from one wafer exhibited output power of 28.94/spl plusmn/0.07 dBm. In addition, data is presented for a 2-stage hybrid amplifier based on the newly developed PHEMTs that is ideally suited to integration into multi-watt Q-band transmitters. <<ETX>>
Efficient methods for prediction of velocity fields in open channel junctions based on the artifical neural network

Measurement results, sediment transport and pollutant dispersion in confluence regions are highly affected by flow structures of open channel junction and it is necessary to find an efficient method that can fully describe the velocity fields in junctions. In this study the velocity field in an open channel junction was investigated by using Artificial Neural Network (ANN) and three dimensional modelling. First, a modified Genetic Algorithm (GA) was introduced, then, an ANN model was optimized and the flow velocity was predicted in a 90 degree channel junction. Also, for three dimensional simulation of the free surface flow in the considered junction ANSYS-CFX software was used. Comparison of the results obtained from ANN and CFX models with laboratory data with root mean square error of 0.094 and 0.182 and percent standard error of prediction of −9.75 and −25.71 respectively, showed that the introduced ANN perform better than CFX in modelling velocity field in open channel junction and it was able to predict accurate in different areas and flow-rates.
A prediction model for surface deformation caused by underground mining based on spatio-temporal associations

Abstract Accurate predictions of the surface deformation caused by underground mining are crucial for the safe development of underground resources. Although surface deformation has been predicted by artificial intelligence (AI) methods, most AI models are established based on the relationships between surface deformation and influential factors. The lack of consideration of the deformation state transition often leads to errors in the prediction results of catastrophic deformation by conventional AI methods. In this respect, this study introduces a surface deformation prediction model based on spatio-temporal association rule mining (STARM). Surface deformation is classified as excessive deformation zone (EDZ) and hysteretic deformation zone (HDZ), representing different surface deformation stage or state. The spatio-temporal association rules between the monitored EDZ and HDZ data are then mined. A surface deformation prediction model is established according to the spatio-temporal relationship between monitored EDZ and HDZ data. The proposed model is verified based on a practical case study of the Chengchao Iron Mine in China. The data collection of the influential factors is not requisite for the proposed model. It can achieve accurate prediction of the catastrophic deformation that was characterized by deformation state transition.
Simulation of Cooling Systems in Gas Turbines

The design of cooling systems for gas turbine engine blades and vanes calls for efficient simulation programs. The main purpose of the described program is to determine the complete boundary condition at the coolant side to support a temperature calculation for the solid.For the simulation of convection and heat pick up of the coolant flow, pressure loss, and further effects to be found in a rotating frame, the cooling systems are represented by networks of nodes and flow elements. Within each flow element the fluid flow is modelled by a system of ordinary differential equations based on the one-dimensional conservation of mass, momentum, and energy. In this respect, the computer program differs from many other network computation programs.Concerning cooling configurations in rotating systems, the solution for a single flow element or the entire flow system is not guaranteed to be unique. This is due to rotational forces In combination with heat transfer and causes considerable computational difficulties which can be overcome by a special path following method in which the angular velocity is selected as the parameter of homotopy.Results of the program are compared with measurements for three applications.Copyright © 1994 by ASME
POMI: Polling-Based Memory Interface for Hybrid Memory System

Modern conventional DRAM main memory system will no longer satisfy the growing demand for capacity and bandwidth on today’s data-intensive applications. Non-Volatile Memory (NVM) has been extensively researched as the alter-native for DRAM-based system due to its higher density and non-volatile characteristics. Hybrid memory system benefits from both DRAM and NVM technologies, however traditional Memory Controller (MC) cannot efficiently track and schedule operations for all the memory devices in heterogeneous systems due to different timing requirements and complex architecture supports of various memory technologies. To address this issue, we propose a hybrid memory architecture framework called POMI. It uses a small buffer chip inserted on each DIMM to decouple operation scheduling from the controller to enable the support for diverse memory technologies in the system. Unlike the conventional DRAM-based system, which relies on the main MC to govern all DIMMs, POMI uses polling-based memory bus protocol for communication and to resolve any bus conflicts between memory modules. The buffer chip on each DIMM will provide feedback information to the main MC so that the polling overhead is trivial. This gives several benefits: technology-independent memory system, higher parallelism, and better scalability. Our experimental results using octa-core workloads show that POMI can efficiently support heterogeneous systems and it outperforms an existing interface for hybrid memory systems by 22.0% on average for memory-intensive workloads.
Waxy Crude Production Management in a Deepwater Subsea Environment

Summary Systematic experimental and modeling approaches to designing a safe operating strategy for a 5-km deepwater-subsea-flowline case study are presented to address unplanned shutdown and restart events for waxy-crude production. The measurements confirmed that the fluid behaves like Bingham plastic when it is allowed to become gel at the seabed temperature of 4°C. The cool-down period was modeled using the transient simulator validated by measurements and was predicted to take 21 hours. The restart pressure was then modeled for both stock-tank and at-line pressure conditions. These restart pressure requirements were found to be 2,500 and 2,100 psi, respectively, for stock-tank and at-line pressure conditions. Also, the use of pour-point depressants demonstrated that the fluid would not form gel at the seabed temperature of 4°C. However, the current shut-in wellhead pressure of 2,500 psi is deemed adequate to restart the lines in the event of unplanned shutdown without the use of chemicals. The presence of a subsea pig-launching pump provides a safety factor for restart in case the line pressure is released to atmospheric conditions. Hence, the operating strategy does not require injection of pour-point depressants at the current state. However, in future when the shut-in wellhead pressure falls below 2,500 psi, the operating strategy is expected to be modified accordingly.
Automated AMF Configuration Difference Generation

Many domains require computer clusters to meet clients’ service level expectations. As cluster size increases, component failure becomes more likely. Rapid failure recovery is required to maintain high availability. The SA Forum has created specifications enabling management of multi-vendor solutions. These long-lived systems require tailored upgrade campaigns to keep their configuration up-to-date. Passed works on SA Forum’s Availability Management Framework (AMF) have created an automated AMF configuration generator and upgrade campaign generator. However, to generate an upgrade campaign for an already configured cluster based on a new target configuration, a configuration difference generator is needed. Furthermore, while Distinguished Names (DNs) usually uniquely identify object in a configuration, configuration generators do not guarantee that DNs in the new configuration will match. DN modification is not possible in a system without object replacement, causing service loss. Non-DN based inter-configuration object association is needed to restore old DNs. Our objective is to devise a technique to perform difference generation with limited knowledge of DNs and to find what data is needed to achieve this. To accomplish this, we analyse the AMF configuration model, then propose assumptions in a top down approach based on maintaining service availability during upgrade. We propose a two phase technique that first associates objects in-between configurations and then outputs the differences. We have implemented a tool that implements this technique on the Eclipse Platform and integrates with MAGIC’s Automated Upgrade Campaign Generator. We then present a case study based on the PHASE example.
Socially Engineering a Polarizing Discourse on Facebook through Malware-Induced Misperception

ABSTRACT This paper reports the findings of a study testing a novel social engineering attack called Malware-induced Misperception (MIM). The goal of the MIM attack is to induce misperception by using a man-in-the-middle malware that covertly rearranges the linguistic content of an authentic social media post, web page, or an e-mail. The MIM attack was tested in controlled settings ( ) where the malware covertly manipulated the linguistic content of a Facebook discourse to induce misperception about the climate of opinion on a polarizing issue (freedom of speech on college campuses) by making conservative-leaning comments appear as liberal-leaning. The induced misperception was assessed in the context of the spiral-of-silence theory. The theory predicts that polarizing issues discourage commenting on social media if an individual’s opinion diverges from the perceived climate of opinion on that issue. Consistent with the theory, the results suggest that the MIM attack can socially engineer the spiral-of-silence effect by manipulating the comments in a Facebook discourse to appeal to the individual’s political ideology and gender identity. Additional Key Words and Phrases: Malware-Induced Misperception (MIM); spiral-of-silence; social engineering; Facebook, web security
Integration of stock markets using autoregressive distributed lag bounds test approach

Financial integration plays a decisive role to the institutional investors for diversification of their investment portfolio(s). This research investigates the integration of selected stock markets (India, Australia, China, Spain, UK, and the USA) from different continents that are highly affected by COVID-19, employing the autoregressive distributed lag approach using daily data from 2 January 2011 to 7 May 2020. The outcomes show evidence of long and short-run integration among the markets. The rest of the markets are co-integrated with the markets of India, China, and UK. India has a long-run equilibrium with the USA and Spain, whereas China has a long-run association with Spain, and the UK has a long-run association with the USA. In short-run, India is positively influenced by the returns of rest of the markets, whereas all the markets under the study except USA influence China. Further, the UK's market is significantly inclined negatively by its own past innovations. © 2022 Inderscience Enterprises Ltd. All rights reserved.
The match between efficiency/flexibility strategy and organisational culture

A mismatch between efficiency/flexibility strategy and organisational culture results in production inefficiency within the firm, whereas a proper match leads to superior performance. This study tries to find out the proper match between them by investigating their joint effect on firm performance. Based on the data of 212 Chinese firms, this research finds that the proper organisational culture for efficiency strategy is characterised by individualism, high power distance, and low uncertainty avoidance, whereas the proper culture for flexibility strategy has the characteristics of collectivism, low power distance, and high uncertainty avoidance.
A remote MQTT-based data monitoring system for energy efficiency in industrial environments

The concept of the new industry seeks not only to improve production processes, but also to bring solutions to environmental problems, in addition to reducing resource consumption, while maintaining high yields. This constant search for process optimization has been the main agent in the development of new technologies aimed at improving the performance of industrial production lines. Thus, this article proposes to raise some important concepts of Industry 4.0, and present the development of a remote IoT-based system that, through MQTT and Modbus protocols, will be responsible for monitoring the entire electrical network of an industrial plant, sending its data to the cloud, where it can be monitored and analyzed by the industry management sector or even by an artificial intelligence system, in a simple and effective way, in real time and from anywhere, in order to assist in decision-making focused on energy efficiency.
Effect of toothless stator design and core and stator conductors eddy current losses in permanent magnet generators

Some advantages of toothless stator design in high-speed permanent magnet generators are presented. A computer-aided method was implemented to study the effect of stator teeth on the eddy current loss in the stator conductors as well as the core loss in the laminations of high-speed permanent magnet generators. The computer-aided method was applied to a 75 kVA, 208 V, 400 Hz, two-pole, permanent magnet generator. A validation of the computed flux density values based on experimentally obtained data is given. Two particular designs, a toothless stator and a conventional stator (with iron teeth), are considered. The conductor eddy current loss and the laminations' core losses are estimated and compared for both designs. The results of a study on the effect of conductor size on the stator conductor eddy current loss are given. >
Climate Change-Induced Drought Impacts, Adaptation and Mitigation Measures in Semi-Arid Pastoral and Agricultural Watersheds

Periodic drought is a major challenge in drought-prone areas of South Asia. A sample survey of farmers (n = 400) from South Asia was conducted to study the farmers’ perception about drought impacts on their socio-economic status, agro-biodiversity, and adaptation besides public institutions’ drought mitigation measures. The results revealed reduced surface and groundwater availability, soil degradation, partial or complete crop failure, increased agricultural fallows and wastelands, biodiversity loss, decrease in agricultural yields, pasture lands, and livestock in drought-impacted South Asia. About 16–26% of the farmers perceived a reduction in the agricultural area and production of commercial crops and millets in drought-prone areas, while changes in the cropping of pulses, oilseeds, horticultural, and fodder crops were minimal. About 57–92% of respondents showed a reduction in the consumption of fruits, vegetables, dairy products, and fish. Unemployment, migration, reduced farm income, and malnutrition were major socio-economic impacts among respondents (38–46%). Despite sufficient public support as a mitigation strategy, the farmers had poor participation (8–65%) for agri-information and adaptation (7–36%) against drought impacts. Hence, researchers, extension agents, and policymakers must develop efficient ‘participatory-mode’ drought adaptation and mitigation policies in watershed-based semi-arid pastoral and agricultural regions of South Asia and similar agro-ecologies across the globe.
Utilization Slurry Coal-Water Fuel

The opportunity of technological and modified lignosulphonate wastes, process water, oxygenized brown coal with high content huminic acid (to 60 %) with alkali usage as plasticizer agent in the coal-water slurry (CWS) production technological process was checked. The CWS stability scheme in alkali additives interaction was suggested. The bituminous and brown coal mixture (10 : 90) CWS was investigated. The anthracite and brown coal relation is from 5 to 95. The discovered regularities demonstrated the slurry properties optimization opportunity in industrial conditions by combined changing of additive quantity and coal physical-chemical composition. The suggested CWS production technology allows solving some questions of ecological safety and resource-saving at the expense of the sources of raw materials assortment expansion. The CWS production industrial scheme on production run equipment without its modernization is developed.
Assessment of spatial audio quality based on sound attributes

Spatial audio technologies become very important in audio broadcast services. But, there is a lack of methods for evaluating spatial audio quality. Standards do not take into account spatial dimension of sound and assessments are limited to the overall quality particularly in the context of audio coding. Through different elicitation methods, a long list of attributes has been established to characterize sound but it is difficult to include them in a listening test. A previous study aimed at clustering attributes in families. Thus 3 families of attributes were highlighted, ''timbre", ''space" and ''defaults". The overall quality and these three families were evaluated in the listening test presented in this article. The test protocol was based on the Mushra recommendation. However it included three anchors specific to each attribute and no reference in order to evaluate quality instead of fidelity. The aim of the experiment described in this paper was to verify the influence of those 3 attributes on the overall quality in a 5.1 reproduction system. It results that the defaults attribute has more influence on the overall quality than the timbre and the timbre. Moreover the presentation of the three attributes on the same interface adds no bias.
Tourist attractions in efficiency analysis

This paper discusses the use of tourist attractions in tourism efficiency analysis. Tourist attractions can be employed either as an input of the production technology or as an environmental factor in a two-stage Data Envelopment Analysis model. An empirical illustration to the case of Chinese provinces underlines that using tourist attractions in different ways can yield different rankings of the units in terms of efficiency. Recommendations for future research are then proposed.
