Efficient Algorithms Relating OFDM Channel Parameters to Filter Weights

Field: Computer Science (Physical Sciences)

Abstract — In high data rate transmissions over wireless channels with long delay spreads inter symbol interference is a major limiting factor. Transmission systems that cancel the interference efficiently are OFDM, cyclic prefix based single carrier (CP-SC) and single carrier with frequency domain equalization (SC-FDE). Although the systems show significant performance differences in terms of necessity of guard periods, peak to average power ratio, performance in fading conditions, and others the algebraic structures of the receiver processing are very similar: FFT Multiplications IFFT. OFDM and CP-SC on the one hand and SC-FDE on the other hand differ mainly in the values of the multipliers. Here efficient algorithms are presented that compute one system parameters from the others. The algorithms are assessed in terms of computational complexity and performance. They can be applied during transmission or training mode. Fast switching between the different systems is feasible. Therefore a multi-mode receiver can be adapted to a particular transmission situation. Index Terms—OFDM, single-carrier, frequency domain equalization, zero forcing algorithm, Schur algorithm. I.
Contingency cost modelling by MATLAB fuzzy toolbox for natural gas maintenance contracts

Field: Decision Sciences (Social Sciences)

The agreed-upon operational contingency cost is a key element of maintenance contracts, especially for the Natural Gas Reduction and Metering Stations. Disputes, claims, and failure to fulfil contractual obligations often stem from poor estimation of the risks associated with contingency costs. Currently, there are no standard rules or methods for companies to estimate these costs. As a result, some practices rely on rough estimates as a percentage of the total contract value without conducting any risk analysis. Others base their estimates on opinions from subject matter experts. This paper addresses the issue of improper contingency cost estimation by: 1) identifying the most influential factors affecting the value of maintenance contracts in the natural gas sector, and 2) developing a fuzzy logic risk analysis model to predict contingency costs based on the specific circumstances of contract signing. The effectiveness of this approach was validated through a real case study of an existing natural gas maintenance contract in Egypt. The results revealed that the most impactful factors were economic, contractual, operational, construction, and regulatory risks, while market and legal risks had the least impact. In addition, the findings show that the proposed model predicts the contingency cost with nearly 94.69% accuracy.
Root stem cell niche networks: it’s complexed! Insights from Arabidopsis

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract The presence of two meristematic cell populations in the root and shoot apex allows plants to grow indefinitely. Due to its simple and predictable tissue organization, the Arabidopsis root apical meristem remains an ideal model to study mechanisms such as stem cell specification, asymmetric cell division, and differentiation in plants. The root stem cell niche consists of a quiescent organizing centre surrounded by mitotically active stem cells, which originate all root tissues. The transcription factors PLETHORA, SCARECROW, and WOX5 form signalling hubs that integrate multiple inputs from an increasing number of proteins implicated in the regulation of stem cell niche function. Recently, locally produced auxin was added to the list of important mobile factors in the stem cell niche. In addition, protein–protein interaction data elegantly demonstrate how parallel pathways can meet in a common objective. Here we discuss how multiple networks converge to specify and maintain the root stem cell niche.

A SIMPLIFIED METHOD OF HEART RATE MEASUREMENT

Field: Medicine (Health Sciences)

ABSTRACT Theoretical and practical considerations require a heart rate measurement method which produces substantial correspondence between heart rate and other autonomic and psychological measures of arousal, and which also is fast and inexpensive. A new heart rate measurement method, the peak rate method. meets these criteria. The peak rate method corresponds as closely to a skin conductance measure of reaction to a stressful movie as does the method of mean cyclic maxima (Malmstrom. Opton, & Lazarus, in press). The peak rate method also yields heart rate curves which are markedly elevated at the most psychologically stressful points during the movie. The peak rate method does not involve the laborious, expensive computations required by the method of mean cyclic maxima. Smoothing heart rate curves by a method of moving averages is also shown to be desirable.
Design and Performance Analysis of a Fuzzy Logic-Based IoT System for Greenhouse Irrigation Control

Field: Engineering (Physical Sciences)

Automatic irrigation has long been used to efficiently irrigate large agricultural areas through drip irrigation systems to minimize water wastage. In greenhouse irrigation, computerized control is essential to improve productivity, as conventional control methods that rely on on-off or proportional control are often inefficient. This research introduces a novel approach to monitor greenhouse environmental conditions and control irrigation duration. The monitoring system architecture consists of sensor nodes and a gateway. The irrigation duration control uses a Fuzzy Logic Controller (FLC) based on the Mamdani method. The FLC is implemented on a NodeMCU ESP8266 board integrated with a DHT22 sensor and a soil moisture sensor. Temperature and soil moisture parameters are used as inputs for the fuzzy logic system in determining the appropriate irrigation duration. The linguistic variables used in the fuzzy membership function include soil moisture (categorized as water, wet, and dry), temperature (categorized as cold, normal, and hot), and watering time (categorized as zero, short, medium, and long). A rule base consisting of nine fuzzy rules was developed based on these membership functions. Experimental results show that the FLC implemented on the NodeMCU ESP8266 has an average accuracy of 99.41% compared to the MATLAB simulation. This shows the fuzzy logic-based system's high accuracy and effectiveness in controlling the duration of greenhouse irrigation. This developed system offers a promising solution to optimize water usage and improve irrigation management in a greenhouse environment.
Advances in Piezoelectric Polymer Composites for Energy Harvesting Applications: A Systematic Review

Field: Materials Science (Physical Sciences)

Abstract Polymeric piezoelectric composites for energy harvesting applications are considered a significant research field which provides the convenience of mechanical flexibility, suitable voltage with sufficient power output, lower manufacturing cost, and rapid processing compared to ceramic‐based composites. This review focuses majorly on the basic theory and principles behind piezoelectric energy harvesting (PEH) devices, followed by specified materials used for the different devices. Different structural configurations associated with fabrication of PEH devices are discussed in detail along with their major advantages and drawbacks. Numerous classes of piezoelectric polymers such as polyvinylidene fluoride, polylactic acid, cellulose, polyamides, polyurea, polyurethanes, and their composites used for energy harvesting applications as a productive alternative of lead‐based piezo‐ceramics, are extensively addressed and explored. Additionally, current global and Indian scenarios associated with PEH devices, major challenges associated with them, and the future perspective of such devices are also reported in this review.
LXI. Vertigo of Labyrinthine Origin following a Chronic Suppurative Otitis Media with Cholesteatoma

Field: Medicine (Health Sciences)

The labyrinth, whether functionally disturbed or the seat of pathologic changes, has held in the immediate past and still continues to hold front rank in the interest of otologists.Weare indebted particularly to the Vienna school for a classification of its diseases which is of great value in didactic teaching and as a pathologic grouping of its disorders.This must of necessity apply largely to typical cases.The otologist is more anxious about those cases less sharply defined clinicallycases which, in their final analysis, confirmed by operation, may be readily labeled pathologically, and yet in their clinical manifestations have presented a reasonable doubt as to the surgeon's attitude in regard to immediate operative interference.The relation of the vestibular apparatus to the brain demands an exact diagnosis and immediate surgical intervention in all pyogenic invasions of the labyrinth, if we are to save life.Under' the above conditions the mortality rate is encouraging.The case outlined below is offered as one with delayed symptoms, and one which was perhaps less clear clinically than many.The following history, taken from the records of the Massachusetts Charitable Eye and Ear Infirmary, occurred during the service of Dr. Crockett and Dr. Mosher, August 11, 1913:
Nurses' Job Satisfaction and Turnover Intentions over a Six‐Year Period of Hospital Downsizing and Amalgamation

Field: Health Professions (Health Sciences)

This longitudinal panel study examined the job satisfaction and turnover intention of 111 nurses employed in four community hospitals in Canada. Data were collected in 1991, again in 1992 following hospital restructuring and downsizing associated with budget cutbacks, in 1995 at the beginning of an amalgamation initiative, and in 1997 during the amalgamation which also involved restructuring and downsizing. In 1992, following the first hospital restructuring and downsizing, nurses reported a significant decrease in satisfaction with their career future and with their hospital but a significant decrease in turnover. A different picture emerged in 1997. Nurses reported a significant decrease in overall job satisfaction, satisfaction with the kind of work they were performing, the amount of work, their physical working conditions, their career future and their hospital. They also reported a significant increase in turnover intention. As Canada is currently entering a period of nurse shortage, the restructuring and downsizing these hospitals engaged in between 1992 and 1997 are likely to have serious consequences for the recruitment and retention of nurses in the future.

Value of radioimmuno-assay of triiodothyronine and thyrotropic hormone in the diagnosis of thyroid disease

Field: Medicine (Health Sciences)

Results of a purely in-vitro test were compared with previously available methods in 425 patients. For triiodothyronine, a normal range must be differentiated from the so-called euthyroid range (0.8-2.0 ng/ml) for patients with euthyroid goitre. The accuracy for triiodothyronine is then more than 95% and in hyperthyroidism 97.5%. It is, therefore, superior to other in-vitro measurements. But a disadvantage is that it is easily influenced by thyroid and extrathyroid factors. Similar accuracy is obtained for the TRH function test (thyrotropine-releasing hormone). Notable is a 'negative' TRH test in 20% of patients with euthyroid goitre. The significance of triiodothyronine determination is decreased in autonomous adenoma, in which the TRH test has an accuracy of 96.5%. In rare diseases of the thyroid all diagnostic possibilities must be taken into account. In ordinary practice a stepwise course is suggested. RT$sub 3$U, T$sub 4$, T$sub 3$ and thyroid scan with sup(99m)Tc pertechnetate are useful as basic tests. PBI is still thought to be important. The second step involves the TRH test rather than $sup 131$I function test. Triiodothyronine determination is best for therapeutic and follow-up purposes, a situation in which TRH test is of limited value. (orig.)

Survey on female genital mutilation/cutting in Jeddah, Saudi Arabia

Field: Medicine (Health Sciences)

Objectives The objective of this study was to determine whether female genital mutilation/cutting (FGM/C) exists in Jeddah, Saudi Arabia. Design A cross-sectional study. Setting King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Participants Between December 2016 and August 2017, women attending the obstetrics and gynaecology clinics were asked to participate in a cross-sectional survey. This included questions on demographics, FGM/C status and type and attitudes towards the practice. Results In a convenience sample of 963 women aged 18 to 75 years, 175 (18.2%) had undergone FGM/C. Compared with women without FGM/C, women with FGM/C were older, married, non-Saudi and had a lower monthly income. Thirty-seven (21.1%) women had had FGM/C with some cutting of body parts (type I or II), 11 (6.3%) with suturing (type III), 46 (26.3%) with no cutting of body parts (type IV) and 81 (46.3%) did not know their type of FGM/C. There was also a significant association between nationality and age at which FGM/C was performed, with Saudi women undergoing the procedure earlier than Egyptian, Somali, Yemeni and Sudanese women. Conclusions FGM/C is prevalent in Jeddah, Saudi Arabia, among immigrant women from other countries, and it is practised among Saudi women. Further research is needed to determine its prevalence.
Adaptive Parameter Selection Variational Mode Decomposition Based on Bayesian Optimization and Its Application to the Detection of ITSC in PMSM

Field: Engineering (Physical Sciences)

Permanent magnet synchronous motor (PMSM) is a vital component of modern industry which is widely used in transport, aerospace and intelligent machinery. In the light of its relatively high frequency of inter-turn short circuit (ITSC) fault, it is valuable to detect the fault accurately and efficiently. Due to the convenience of motor vibration signal measurement, more attention has been paid to fault detection methods based on vibration signal. As a nonstationary, nonlinear signal, vibration signal is highly susceptible to external noise interference. Variational mode decomposition (VMD) has a wide range of applications in the field of nonlinear signal analysis, but the processing ability to the signal is affected by the parameter setting. Hence, a Bayesian optimized adaptive parameter selection variational mode decomposition (BOAPS-VMD) signal processing method is proposed and applied to detect the ITSC in PMSM. Firstly, the motor vibration signal is decomposed through BOAPS-VMD, and the intrinsic mode functions (IMFs) are obtained. Secondly, the cumulative variance contribution rate (C-VCR) is applied to identify the IMFs that contain fault signature information. Finally, using Hilbert transform (HT) to further analyze the IMFs that are identified. The results are output in 3D time-frequency diagrams to enhance the representation of fault signatures. The effectiveness and accuracy of the BOAPS-VMD were validated through the finite element simulation and experiment. The study shows that the BOAPS-VMD effectively improves the modal mixing phenomenon, has better noise robustness, improves the accuracy of fault detection, and has better engineering applicability.
