Automatic Power Factor Correction Using a Harmonic-Suppressed TCR Equipped with a New Adaptive Current Controller

In this paper, a new continuously and linearly controlled capacitive static VAR compensator is proposed for the automatic power factor correction of inductive single phase loads in 220V 50Hz power system networks. The compensator is constructed of a harmonic-suppressed TCR equipped with a new adaptive current controller. The harmonic-suppressed TCR is a new configuration that includes a thyristor controlled reactor (TCR) shunted by a passive third harmonic filter. In addition, the parallel configuration is connected to an AC source via a series first harmonic filter. The harmonic-suppressed TCR is designed so that negligible harmonic current components are injected into the AC source. The compensator is equipped with a new adaptive closed loop current controller, which responds linearly to reactive current demands. The no load operating losses of this compensator are negligible when compared to its capacitive reactive current rating. The proposed system is validated on PSpice which is very close in terms of performance to real hardware.
Critical Investigation into the Applicability of the Learning Curve Theory to Rebar Fixing Labor Productivity

The learning phenomenon has proved applicable in various industries, especially those associated with mass productions such as aircraft and automobile assembly. The learning process in labor-intensive industries is assumed to be more significant in the sense that automated work is constrained by the fact that machines cannot benefit from previous experience and therefore would not “learn” to run any faster or increase the rate of production. Several previous investigations into the applicability of learning curve theory to the construction industry proved the importance of this concept to labor productivity. Nonetheless, a thorough examination of the literature revealed a dearth of research into the effect of learning on the rebar fixing trade. Therefore, the objective of this research is to explore the influence of recurring building floor configurations on rebar fixing labor productivity. To achieve this objective, fixing labor inputs of beams and slabs from 21 multistorey residential building floors we.
Consistency and accuracy of selected FWD backcalculation software for computing layer modulus of airport pavements

Abstract Falling weight deflectometer (FWD) data are generally processed through backcalculation software for computing layer modulus of airport pavements. Though a number of backcalculation software are currently available, it is not known that software produces the most consistent and accurate results. Inconsistent and inaccurate backcalculation software can take a significant toll on the overlay and rehabilitation design of airport pavements as modulus being the inputs for such design calculations. Most backcalculation software requires an initial value of modulus, known as seed modulus, to initiate simulations. Unfortunately, in many of the software, the outputs vary with the initial choice of seed modulus (consistency). In addition, depending on the software algorithm, the final output differs from the laboratory measured value of modulus (accuracy). In this study, three backcalculation software programs are evaluated for consistency and accuracy. They are BAKFAA, MODULUS and EVERCALC. The major goal is to determine the most consistent and accurate software for determining layer modulus of airport pavements in New Mexico. Consistency of software is determined by comparing outputs from three sets of input data from FWD tests at identical locations with three magnitudes of loads: 40·03, 53·38 and 71·17 kN. Laboratory tests are conducted for modulus and tensile strength of asphalt and soil samples collected from the same locations of FWD tests. Software accuracy is determined based on the distribution and magnitude of the variance of laboratory and FWD modulus. Laboratory tensile stress is also compared with the backcalculated tensile stress using KENLAYER, a multilayer elastic analysis software. Study results show that EVERCALC software produces more consistent and accurate modulus values than the BAKFAA and MODULUS software. Therefore, EVERCALC is recommended for analyzing layer modulus of airport pavements.
Sequencing batch reactors for biological wastewater treatment

The Sequencing Batch Reactor (SBR) is one of several periodically operated, suspended‐growth activated sludge systems. This periodic process accomplishes (in time) in one tank the same unit operations and processes that a conventional continuous‐flow system carries out in separate tanks. This paper discusses the history of periodic process development as well as the relationship of the SBR to other periodic processes and continuous flow‐systems. Bench‐and full‐scale performance of the SBR are described for synthetic substrates, municipal and industrial waste waters, and organics in Ieachates from hazardous waste disposal sites. Examples are given for the removal of biodegradable organics and nutrients (both nitrogen and phosphorus) and for the control of filamentous organisms. A brief discussion of the organism selection features of the SBR is presented as well as a comparison with genetic engineering approaches. The paper closes with two design examples, one dedicated to the treatment of industrial or ha.
Cerebellar stroke complicating coronary catheterization: a case report

Cerebrovascular events are rare but devastating events that can complicate any coronary intervention. In the vast majority of cases, they involve major cerebral arteries. We report the case of a 56-year-old woman admitted for unstable angina associated with severe left systolic dysfunction. She developed moderate cerebellar stroke while undergoing percutaneous coronary intervention, with a national institutes of health stroke scale score of 5. Immediate systemic thrombolysis was performed, but her neurological status deteriorated. A large hemorrhagic transformation was then diagnosed, and she died despite surgical intervention. Periprocedural strokes are marred with high morbidity and mortality, therefore preventionis key, as many risk factors can be controlled or mitigated. Our patient presented many of these factors; they can be procedure-related (transfemoral approach, anticoagulation) or patient-related (age, diabetes mellitus, uncontrolled hypertension, diffuse atherosclerosis).
Cogeneration in sugar industries: technology options and performance parameters - a review.

ABSTRACT This article presents a review of different technological options that are presently being practiced by sugar mills, and technological options that are identified as potentially promising future technologies. Different indices used to gauge the thermodynamic performance of cogeneration plants and facilitate the comparison of alternative systems are discussed. The most important performance parameters used to assess the steam turbine cogeneration plants in general and sugar mill cogeneration plants in particular are defined and developed. Criteria such as energy utilization factor, heat-to-power ratio, fuel energy savings ratio, exergetic efficiency and power generated per tonne of cane (tc) prove to be more important and relevant. Biomass-integrated gasifier/gas turbine cogeneration (BIG-GT) and biomass gasifier combined with steam injected gas turbine cogeneration (BIG-STIG) are considered as potentially promising future technologies. The existing modern, high pressure, high efficiency, steam tu.
Electrostatic Forces Mediate the Specificity of RHO GTPase-GDI Interactions

Three decades of research have documented the spatiotemporal dynamics of RHO family GTPase membrane extraction regulated by guanine nucleotide dissociation inhibitors (GDIs), but the interplay of the kinetic mechanism and structural specificity of these interactions is as yet unresolved. To address this, we reconstituted the GDI-controlled spatial segregation of geranylgeranylated RHO protein RAC1 in vitro. Various biochemical and biophysical measurements provided unprecedented mechanistic details for GDI function with respect to RHO protein dynamics. We determined that membrane extraction of RHO GTPases by GDI occurs via a 3-step mechanism: (1) GDI non-specifically associates with the switch regions of the RHO GTPases; (2) an electrostatic switch determines the interaction specificity between the C-terminal polybasic region of RHO GTPases and two distinct negatively-charged clusters of GDI1; (3) a non-specific displacement of geranylgeranyl moiety from the membrane sequesters it into a hydrophobic cleft, effectively shielding it from the aqueous milieu. This study substantially extends the model for the mechanism of GDI-regulated RHO GTPase extraction from the membrane, and could have implications for clinical studies and drug development.
SUPERCONDUCTING RF IN STORAGE-RING-BASED LIGHT SOURCES *

Third generation synchrotron light sources are small storage rings operating in the energy range of 1.5 to 3.5 GeV. These machines require relatively low total accelerating voltage and high RF power to compensate particle beam energy losses to X-rays. Strong damping of Higher-Order Modes (HOMs) is also necessary for stable operation of high-current multi-bunch beams. Super- conducting HOM-damped single-cell cavities are ideal for such applications. Their ability to transfer almost all RF power to the beam and to operate at high accelerating gap voltages reduces the number of installed cavities thus improving overall efficiency of the RF systems. In the past many laboratories were reluctant to use super- conducting RF (SRF) technology as it was considered more complex than conventional copper accelerating structures. Proliferation of superconducting insertion devices made having a cryogenic plant the necessity for every contemporary light source thus providing infrastructure for SRF as well. With the successful and reliable operation of HOM-damped cavities at CESR and KEKB, technological developments at CERN and other laboratories and the technology transfer to industry, SRF has become the readily available technology of choice for new and small labs with no prior experience in the field. In this paper we will describe the use of superconducting cavities in fundamental RF systems and as passive structures for bunch lengthening. Operating experience and recent achievements from light sources around the world will be discussed.

Prognostic Impact of Sleep Patterns and Related-Drugs in Patients with Heart Failure

Sleep disturbances are frequent among patients with heart failure (HF). We hypothesized that self-reported sleep disturbances are associated with a poor prognosis in patients with HF. A longitudinal study of 119 patients with HF was carried out to assess the association between sleep disturbances and the occurrence of major cardiovascular events (MACE). All patients with HF completed self-administered questionnaires on sleepiness, fatigue, insomnia, quality of sleep, sleep patterns, anxiety and depressive symptoms, and central nervous system (CNS) drugs intake. Patients were followed for a median of 888 days. Cox models were used to estimate the risk of MACE associated with baseline sleep characteristics. After adjustment for age, the risk of a future MACE increased with CNS drugs intake, sleep quality and insomnia scores as well with increased sleep latency, decreased sleep efficiency and total sleep time. However, after adjustment for left ventricular ejection fraction and hypercholesterolemia the HR failed to be significant except for CNS drugs and total sleep time. CNS drugs intake and decreased total sleep time were independently associated with an increased risk of MACE in patients with HF. Routine assessment of self-reported sleep disturbances should be considered to prevent the natural progression of HF.
Performance of the generalized cross correlator in the presence of a strong spectral peak in the signal

Under consideration is the effectiveness of various windowing functions in the generalized correlator when a strong spectral peak, i.e., a sinusoid, is present in the signal. The windows W HBII (ω) and W SCOT (ω) or W R (ω) avoid the ambiguity problem that is encountered by the other windows when sinusoids are present in the signal.
Gliogenic Potential of Single Pallial Radial Glial Cells in Lower Cortical Layers

During embryonic development, progenitor cells are progressively restricted in their potential to generate different neural cells. A specific progenitor cell type, the radial glial cells, divides symmetrically and then asymmetrically to produce neurons, astrocytes, oligodendrocytes, and NG2-glia in the cerebral cortex. However, the potential of individual progenitors to form glial lineages remains poorly understood. To further investigate the cell progeny of single pallial GFAP-expressing progenitors, we used the in vivo genetic lineage-tracing method, the UbC-(GFAP-PB)-StarTrack. After targeting those progenitors in embryonic mice brains, we tracked their adult glial progeny in lower cortical layers. Clonal analyses revealed the presence of clones containing sibling cells of either a glial cell type (uniform clones) or two different glial cell types (mixed clones). Further, the clonal size and rostro-caudal cell dispersion of sibling cells differed depending on the cell type. We concluded that pallial E14 neural progenitors are a heterogeneous cell population with respect to which glial cell type they produce, as well as the clonal size of their cell progeny.
Super‐twisting disturbance observer‐based intelligence adaptive fault‐tolerant formation control for a class of CAUS with switching topology

This paper investigates a super‐twisting disturbance observer (STDO)‐based intelligence adaptive fault‐tolerant formation control structure for cluster aerospace unmanned systems (CAUSs) subject to the external disturbances and actuator faults with switching topology. Firstly, in order to surmount the effects of the actuator unknown control gain and the deviation faults, a number of adaptive laws are developed. Secondly, benefiting from the precisely performance of STDO, we introduced a compensation term into the controller design to overcome the influence of the high dynamic external disturbances. Moreover, in order to achieve the communication and update of the information, CAUS controller maintains the leader‐following consensus under the switching communication topology, which can promote the adaptability of the time‐varying actual task demands. Numerical simulation results are demonstrated to illustrate the effectiveness and advantages of the proposed STDO‐based intelligence adaptive formation control method for the CAUS.
Plastic Hinge Length Considering Shear Reversal in Reinforced Concrete Elements

Concrete structures can dissipate seismic energy during moderate to severe earthquakes by deforming inelastically. The inelastic deformation should concentrate at specific locations, referred to as plastic hinges. An experimental program was conducted to explore the factors affecting plastic hinge formation and length in beams. The test variables included the concrete compressive strength, bottom/top reinforcement ratio, shear strength, and shear demand. The increase in concrete strength did not influence the plastic hinge length, which was increased significantly by the effect of shear spread. The shear spread depended on the shear strength/demand ratio and was predicted successfully by the analytical model proposed.
Incremental Experience in In Vitro Primary Culture of Human Pulmonary Arterial Endothelial Cells Harvested from Swan-Ganz Pulmonary Arterial Catheters

Pulmonary arterial hypertension (PAH) is a devastating condition affecting the pulmonary microvascular wall and endothelium, resulting in their partial or total obstruction. Despite a combination of expensive vasodilatory therapies, mortality remains high. Personalized therapeutic approaches, based on access to patient material to unravel patient specificities, could move the field forward. An innovative technique involving harvesting pulmonary arterial endothelial cells (PAECs) at the time of diagnosis was recently described. The aim of the present study was to fine-tune the initial technique and to phenotype the evolution of PAECs in vitro subcultures. PAECs were harvested from Swan-Ganz pulmonary arterial catheters during routine diagnostic or follow up right heart catheterization. Collected PAECs were phenotyped by flow cytometry and immunofluorescence focusing on endothelial-specific markers. We highlight the ability to harvest patients’ PAECs and to maintain them for up to 7–12 subcultures. By tracking the endothelial phenotype, we observed that PAECs could maintain an endothelial phenotype for several weeks in culture. The present study highlights the unique opportunity to obtain homogeneous subcultures of primary PAECs from patients at diagnosis and follow-up. In addition, it opens promising perspectives regarding tailored precision medicine for patients suffering from rare pulmonary vascular diseases.
Evaluation of Tip Capacity Analysis Model for Drilled Shafts in Gravelly Soils

This paper examines an analysis model for predicting the tip capacity of drilled shaft foundations under gravelly soils. Forty one static compression load test data are utilized for this purpose. Comparison of predicted and measured results demonstrates that the prediction model greatly overestimates the tip capacity of drilled shafts. Further assessment on the model reveals a greater variation in three coefficients; the effective overburden pressure ( ), the overburden bearing capacity factor (Nq); and the bearing capacity modifier for soil rigidity (ζqr). These factors are modified from the back-analysis of the drilled shaft load test results. Varying effective shaft depths are considered for the back-calculation to explore their effects on capacity behavior. Based on the analyses, the recommended effective shaft depth for the evaluation of effective overburden pressure is limited to 15B (B=shaft diameter). The Nq and ζqr are enhanced while maintaining their basic relationship with the soil effective friction angle, in which the Nq increases and ζqr decreases as increases. Specific design recommendations for the tip bearing capacity analysis of drilled shafts in gravelly soils are given for engineering practice.
Determinants of China's Military Expenditures: 1965-93

China's military expenditures are of great concern to many. Although numerous articles have been written on this subject, little empirical work has been conducted to identify the determinants of China's military expenditures. This article fills this void by empirically showing that China's GNP, its rivals' military expenditures, its border wars with neighboring countries, and its leadership's preferences are likely determinants of China's military expenditures. Specifically, using the ACDA data, this study indicates that China's military expenditures are positively influenced by China's GNP, its rivals' military expenditures, and China's lagged military expenditures during the period 1965-93. In addition, the change in the Chinese leadership's top priority from preparing for war to economic development after 1979 has a negative impact on China's military expenditures, but the border wars with the Soviet Union and Vietnam do not have a significant impact. Similar results are obtained by using official Chinese data. This suggests that the difference between the official Chinese data and the ACDA data may be systematic so that the relationship between China's military expenditures and their determinants are qualitatively the same regardless of which dataset is used.
Detection of abscisic acid and relative transcript abundance in Syntrichia caninervis Mitt.

ABSTRACT Introduction. Abscisic acid (ABA) is a plant hormone known to regulate environmental stress responses in various species. Endogenous ABA has been detected in only a limited number of bryophyte species. Methods. Samples of the desiccation-tolerant moss Syntrichia caninervis Mitt. were analysed by ultra-performance liquid chromatography–mass spectrometry to determine the endogenous ABA content of the gametophores. Quantitative real-time PCR was conducted to investigate the transcript abundance of ABA-related genes (ZEP, NCED3, SnRK2, ABI1 and ABI5) during dehydration and rehydration and in response to exogenous ABA and cold stress. Key results. Over a 24 h period of dehydration, the mean ABA concentration of the gametophores ranged from 7.96 to 30.87 ng/g dry weight, being maximal at 6 h. The expression of ABA-related genes changed in response to abiotic stress. Conclusions. The results show that Syntrichia caninervis can generate ABA and suggest that ABA has crucial functions in the stress responses of this species. Our findings establish a foundation for further research on the physiological roles of ABA in S. caninervis and help extend our understanding of the biosynthetic, metabolic and signalling pathways of ABA in bryophytes.
