Parental attitudes towards Breastfeeding practices in comparison to Formula feeding and its sociodemographic determinants
No full textIntroduction
Breastfeeding has been merited as a pertinent source of nutrition for growth and development of the young infants. Despite ample health education and awareness endeavors about the advantages of breastfeeding, the current exclusive breastfeeding rates are still on the lower side in developing countries like India.
Materials and methods
This was a prospective,cross sectional study conducted at Dept of Pediatrics in a zonal hospital in North India. To assess the maternal and paternal attitudes towards breastfeeding and formula feeding, we prepared a17 point questionnaire adapted from IIFAS (lowa Infant Feeding Attitude Scale). IIFAS is a reliable and validated tool for assessing attitudes toward breastfeeding .
Results
There is overall statistically significant difference seen among the level of education and positive breastfeeding attitudes (p = .001) and this was more noticeable among mothers (p=0.00) than fathers (p = 0.480). Professional mothers and housewives do not have any differences (p=0.223) in positive attitudes towards breastfeeding, but contrary to popular belief, professional mothers had more positive attitude(average score=28.5±2.4) towards breastfeeding than house wives (average score = 27.7±2.6).
Discussion
This study highlights both the maternal and paternal attitudes towards breastfeeding in comparison to the formula feeds in a developing country like India along with various socio- demographic factors which influence these attitudes. These findings speaks volumes about the need for considerable improvement of infrastructure for breastfeeding at public places and constituting a set policy for breastfeeding in developing countries like India.

A review of emerging hydroforming technologies: design considerations, parametric studies, and recent innovations
No full textAbstract Hydroforming is a modern metal-forming process prominently used in the shipbuilding, aerospace, and automotive industries for forming lightweight, complex-shaped geometries due to their inherent process benefits. But this process faces challenges such as limited material selection, high tooling costs, and complex process control for obtaining a defect-free part with uniform thickness. Researchers are constantly innovating and advancing hydroforming technologies to overcome these limitations. This work reviews emerging tube and sheet hydroforming technologies, considering parametric effects and design considerations, particularly for micro-domain applications. Further, a wider acceptance of the hydroforming process in different industries is explored by discussing the studies that tried to improve the efficiency and quality of the hydroforming process. This study observed that better formability could be achieved in hydroforming with appropriate intermediate heat treatment, proper lubrication, the correct design of loading paths, and temperature distribution. In tube hydroforming, wrinkles, necking, and cracking observed to be largely reduced by properly selecting the internal pressure and feeding. The precise protrusion height and uniform thickness at different joint cross-sections in tube forming are found to be significantly influenced by the strain-hardening exponent, loading path, and friction coefficient. Electrohydraulic forming is found being increasingly used due to its higher productivity and lower product cost. However, further research is required to achieve complex sheet geometries with sharp corners. This research emphasizes that advanced research, artificial intelligence integration, and the exploration of alternative materials can improve the performance of the hydroforming process
Characteristics of Offshore Wind Farm Wakes and their Impact on Wind Power Production from Long-term Modelling and Measurements
No full textAs the penetration of offshore wind farms continues to increase in Western Europe, the North Sea in particular is becoming more densely populated by offshore wind farms. Wind turbine wakes have been a topic of great research in the field of wind energy for some time, however the industry now seeks an understanding of the in- fluence of the wake from one wind farm on the performance of a downstream wind farm. Few studies have been conducted to this end. This project will contribute to the greater work of the DTU OffshoreWake project. This master thesis will use 2018 SCADA data provided by the project partner, Vattenfall, meteorological mast data provided by BMWi and PTJ, and the author will conduct and analyse simulations using the Weather Research and Forecasting (WRF) model for the same time period. Additionally, this project will comment on the validity of the wind farm param- eterization sub-models within WRF, and investigate the dependance of wakes on climatological variables and offer a longer term study than previously conducted, therefore giving the possibility of conclusions with greater certainty based on this body of work. It is found that both of the wind farm parameterization schemes (Fitch and EWP) used in this project can reasonable replicate the trends seen in the measured data. The EWP scheme tends to over-predict both gross power produc- tion and mean wind speed, while the Fitch scheme tends to underpredict the same. However, for both schemes, good agreement is found with measurements when the wind speed is accurately predicted. Wind farm wakes are observed in SCADA data and WRF simulations. The magnitude of velocity deficit tends to increase for sea- sons in which atmospherically stable conditions are most frequent. In the region of study, these stable conditions are accompanied by generally lower wind speeds and winds which prevail from the east.DTU Wind Energy-M-0315OffshoreWakeAerospace Engineering | Aerodynamics and Wind Energ
[[alternative]]The study on the component analysis of number series completion test
No full text[[abstract]]The purposes of this study were to decompose the difficulty level of number se
ries completion task, and to examine if the constructs for detecting regular n
umber series and irregular number series are different. Two studies were condu
cted, studyⅠwith the pretest data of the math test in the Youth Intelligence
Test, and studyⅡwith the number series completion test developed by the autho
r. Both studies focused on the test component analysis and the component param
eter estimation that were calculated by using stepwise regression model and th
e Linear Logistic Latent Trait Model.The major findings of this study are as f
ollows:1. The constructs to solve both regular number series items and irregul
ar number series items are of the same dimension.1. In studyⅠ, the major diff
iculty accountability of number series completion task comes from three compon
ents: if the series is moving or not, period of the series, and if the series
is spurious identity or not. These three components significantly and positive
ly related to the difficulty level of number series completion task.3. In stud
yⅡ, the difficulty accountability of number series completion task comes from
four components: if the same figures of the series are adjacent or not, if th
e series is regular or not, if the number of the same figures equals to the pe
riod of the string or not, and if the series is spurious identity or not. The
first three components negatively related to difficulty level of number series
completion task, while the last component positively related to the difficult
y level of number series completion task.4. In several cases, the interaction
term among the components is able to account for the difficulty level of numbe
r series completion task.5. More components are needed to increase the account
ability of items' difficulty of number series completion task according to the
result, especially when the test size is getting large.6. The result shows th
at both stepwise regression and LLTM methods for estimation of component param
eter are similar.
Tracking the History of Romani Publications: Challenges Presented by Flawed Data
No full textThis is the preprint of the published version, identical except for the correction of one typo.Romani is a language of northern Indic origin spoken natively by an estimated 2.5 million people, primarily in Eurasia but also in North America. The history of publication patterns in Romani has not been well documented. Extracting data about this history based on available information in large bibliographic databases such as OCLC WorldCat has been hampered by unfortunate misap- plication of certain language codes, making it all but impossible to filter search results efficiently using Romani language as a param- eter. The author discusses how he was able to correct much of this inaccurate data in OCLC WorldCat
A metric and mixed-integerprogramming-based approach for resource allocation in dynamic real-time systems
No full textDynamic real-time systems such as embedded sys-tems operate in environments in which several param-eters vary at run time. These systems must satisfy several performance requirements. Resource allocation on these systems becomes challenging because varia-tions of run-time parameters may cause violations of the performance requirements. Performance violations result in the need for dynamic re-allocation, which is a costly operation. In this paper, a method for allo-cating resources such that the allocation can sustain the system in the light of a continuously changing en-vironment is developed. We introduce a novel perfor-mance metric called MAIL (maximum allowable in-crease in load) to capture the eectiveness of a resource allocation. Given a resource allocation, MAIL quan-ti es the amount of additional load that can be sus-tained by the system without any performance viola-tions. A Mixed-Integer-Programming-based approach (MIP) is developed to determine a resource allocation that has the highest MAIL value. Using simulations, several sets of experiments are conducted to evaluate our heuristics in various scenarios of machine an
