Performance Analysis of Filtered OFDM using MLE for Wireless
Communication Networks
Authors: Hazareena Asia , Shekhara Kavitha , Bellary Mohammed Zakir 
Published: May 2024

Introduction:
OFDM has evolved as an effective modulation format for 4G mobile network
technologies, Long-Term Evolution, and Worldwide Interoperability for Microwave Access.
OFDM is the modulation technique adopted for communication standards such as DSL, wireless
LAN, DVB, and DAB. However, because CP-OFDM has considerable out-of-band emission that may
interfere with transmissions in adjacent bands and applies a single set of parameters to the whole band
to fulfill a given service, it is unable to accommodate the diversity of services. The objective of the
research is to develop a novel waveform with better adaptability than CP-OFDM that employs filters
to increase spectrum containment. In this view, an FIR filter that uses the Blackman window function
to lessen the OOBE is proposed in this manuscript. Filtered OFDM is sensitive to carrier frequency
offset (CFO). CFO increases the Inter-Carrier Interference (ICI) in F-OFDM systems. However, research
work that combines the CFO compensation technique with filtered OFDM has not been listed
in the literature so far.

Methods:
In this paper, Maximum likelihood estimation is used to cancel the ICI caused by the CFO.
The high PAPR of filtered OFDM is one of its drawbacks. The amplitude clipping method is used to
reduce the PAPR. The distortion caused by amplitude clipping is prevented by filters used in the FOFDM
system.

Highlights:
• A novel waveform addressing OOBE issues in OFDM is developed for 4G wireless communication
networks.
• An innovative solution using MLE is proposed to address the challenges faced by the filtered
OFDM system due to the CFO.
• Article addresses the high PAPR problem of filtered OFDM.

Results:
The performance of filtered OFDM with amplitude clipping is analyzed in terms of BER,
PSD, and PAPR over the AWGN channel.

Conclusion:
Simulation results show that, when compared to the traditional OFDM system, such a
combined method effectively suppresses PAPR while maintaining good BER (Bit Error Rate) and
OOBE performance.

Modifying the curriculum is often necessary for autistic children to effectively engage in their learning. Interestingly, a particular learning process was discovered that proved to be effective without any need for modification - specifically, teaching science to an autistic child. This discovery calls for further investigation. This study aims to provide a comprehensive description of the unique traits exhibited by autistic children who excel in learning science without the need for any modifications. This study utilized the Spradley analysis method, which involves domain analysis, taxonomic analysis, componential analysis, and cultural theme analysis. The participants in this study consisted of elementary school students in the 3rd grade who have autism. They were selected using the purposive sampling method. The data collection involved conducting interviews, examining documentation, and studying artifacts. The findings of the study indicate that children with mild autism can effectively learn science without requiring any adjustments, while still receiving necessary accommodations. Tasks can be effectively completed with the support of teachers and the assistance of paraprofessionals. Autistic children demonstrate proficiency in basic science process skills, creativity, and fine motor skills. They also exhibit a positive affect and are able to socialize effectively. Addressing focus and emotional issues involves implementing structured meal plans, providing parents with guidance on educating their children, and fostering strong collaboration with teachers.

Authors: Gouy Giulia , Attali Luisa , Voillot Paméla , Fournet Patrick , Agostini Aubert 
Published: May 2024

Background
Abortion (also known as termination of pregnancy) is an essential element of women’s reproductive health care. Feedback from women who underwent medical termination of pregnancy about their experience is crucial to help practitioners identify women’s needs and develop necessary tools to improve the abortion care process. However, the collection of this feedback is quite challenging. Social media offer anonymity for women who share their abortion experience.

Objective
This exploratory infodemiology study aimed to analyze, through French social media posts, personal medical symptoms and the different experiences and information dynamics associated with the medical abortion process.

Methods
A retrospective study was performed by analyzing posts geolocated in France and published from January 1, 2017, to November 30, 2021. Posts were extracted from all French-language general and specialized publicly available web forums using specific keywords. Extracted messages were cleaned and pseudonymized. Automatic natural language processing methods were used to identify posts from women having experienced medical abortion. Biterm topic modeling was used to identify the main discussion themes and the Medical Dictionary for Regulatory Activities was used to identify medical terms. Encountered difficulties were explored using qualitative research methods until the saturation of concepts was reached.

Results
Analysis of 5398 identified posts (3409 users) led to the identification of 9 major topics: personal experience (n=2413 posts, 44.7%), community support (n=1058, 19.6%), pain and bleeding (n=797, 14.8%), psychological experience (n=760, 14.1%), questioned efficacy (n=410, 7.6%), social pressure (n=373, 6.9%), positive experiences (n=257, 4.8%), menstrual cycle disorders (n=107, 2%), and reported inefficacy (n=104, 1.9%). Pain, which was mentioned in 1627 (30.1%) of the 5398 posts by 1024 (30.0%) of the 3409 users, was the most frequently reported medical term. Pain was considered severe to unbearable in 24.5% of the cases (399 of the 1627 posts). Lack of information was the most frequently reported difficulty during and after the process.

Conclusions
Our findings suggest that French women used social media to share their experiences, offer and find support, and provide and receive information regarding medical abortion. Infodemiology appears to be a useful tool to obtain women’s feedback, therefore offering the opportunity to enhance care in women undergoing medical abortion.
Catalytic Cracking of Oily Sludge using Nickel Metal Catalyst Embedded in Silica Derived from Adsorbent in a Gas Process Plant
Authors: Jayanti Novita , Nazarudin  , Mulyono Panut 
Published: May 2024

Abstract. One of the Oily Sludge (OS) recycling methods is through catalytic cracking. This process involves the reaction breaking down large molecules into smaller ones with the help of a catalyst. Nickel (Ni) metal is often used as a catalyst because it can increase fuel liquid yield while reducing the coke formation. To enhance its performance, Ni metal can be embedded in a carrier material like Silica to form the Ni-Silica catalyst. In this research, OS sourced from a Gas Process Plant is treated with catalytic cracking using Ni-Silica, where the Silica used is derived from an Adsorbent activated with NaOH. Optimization of the cracking conditions is carried out using Response Surface Methodology (RSM) with a Box-Behnken design. The optimized cracking reaction conditions include temperature (713 K, 723 K, and 733 K), time (50 min, 60 min, and 70 min), and catalyst-to-OS ratio of 1:5, 1:6, and 1:7. Statistical analysis indicates that the relationship between the reaction condition variables and the Oil Liquid Product (OLP) falls into the moderate category, as shown by the coefficient of determination (R²) of 0.5. The calculated F-value for the deviation from the mathematical model is smaller than the F-Table value (9.2) at both 5% and 1% significance levels, with a value of 0.6. This indicates that the mathematical model generated can be accepted as the mathematical model within the range of reaction conditions in this study. Calculus analysis reveals that the optimum reaction conditions are a temperature of 717.34 K, a time of 58.58 min, and a catalyst-to-OS ratio of 1:6, 15. Canonical analysis indicates that for OLP, λ1= [-12.38], λ2= [-2.27], and λ3= [4.50], where lambda values indicate that the most sensitive response surface parameter for OLP is temperature, followed by the catalyst-to-sample ratio, and the least sensitive is reaction time.

This article analyzes comfort and enjoyment between networks and viewers is seen in reality show's popularity. This study conducting skeptical post-modern by Rosenau (1991) as for the approach. The study-case approach focuses on the planning and execution of research. It appears that the cultural diversity that is being portrayed on the reality TV program 90 Day Fiancé through Nicole and Azan’s scenes is intended to be a well-liked sub-genre of alternative fiction. As a result, the scenes and everything else in the show might all have been made up to suit the preferences of the viewers. Thus, there are two opposing viewpoints among viewers in this case: first, those who criticize 90 Day Fiancé while also bringing up the subject of cultural diversity as a result of their critical thoughts; and second, those who do so without bringing up the subject at all because they only view the show as entertainment.
