Abstract:
Analisis keandalan akhir-akhir ini semakin banyak yang menggunakanya seiring dengan perkembangan ilmu pengetahuan dan teknologi. Bukan saja diaplikasikan pada bidang statistik yang menjadi induknya tetapi juga diberbagai bidang terutama pada analisis struktur yang erat hubungannya dengan peramalan dan analisa resiko. Floating Storage Offloading (FSO) merupakan struktur terapung di lautan seperti kapal tanker yang berfungsi untuk melakukan bongkar muat minyak. Dengan keberadaan FSO di lingkungan laut di mana tingkat ketidak pastian yang begitu tinggi maka analisis keandalan merupakan faktor penting yang seharusnya dilakukan. Dengan bantuan metode simulasi Monte Carlo maka analisis ini dapat dilakuan. Analisa Monte Carlo akan memberikan hasil yang dapat dijadikan rekomendasi dalam menganalisa kekuatan FSO. Metodologi yang dipakai untuk melakukan analisa ini adalah mengumpulkan data, menetapkan ambang batas keselamatan, menentukan karasteristik peubah dasar, dan kemudian melakukan simulasi Monte Carlo. Dengan demikian maka sesungguhnya analisis keandalan ini dapat diterapkan pada tahap-tahap perancangan dan perencanaan FOS atau kapal-kapal lain.

Abstract:
<p>Free-space optical (FSO) links provide high speed point-to-point wireless communication, but its availability can easily be affected by weather conditions. In heavy rainfall regions, FSO links are relatively sensitive to rain. Availability prediction of FSO is indispensable part, especially in tropical areas. In this paper, methods to predict FSO link availability are presented. The overall performance of FSO link is described in terms of the availability that can be achieved over anticipated link distance. The availability prediction methods demonstrated for an FSO link ranges up to 5 km. The availability prediction methods are based on long-term statistics of atmospheric attenuations and FSO link budget under tropical climate condition. In tropical regions, for a terrestrial FSO link, carrier class availability can be achieved over a few hundred meters only; whereas enterprise class availability can be achieved over a few kilometers link distances. </p>

Abstract:
The present study has been conducted to identify the sensitivity in the pre-dominant farming systems of Western plain zone of Uttar Pradesh (WPZ) considering the importance of gender specific technologies much needed for better efficiency and productivity of farming systems. Four pre-dominant farming systems have been identified in WPZ of Uttar Pradesh with the highest area share (57.1%) and highest farmer distribution (62.9%) in FS1: Crop + Dairy (1C+1-2B). The highest net return was found in FS2: Crop + Horticulture (Fruits) + Dairy (2C+ 1-2 B), whereas the lowest net return was noticed in FS3: Crop + Horticulture (Vegetables) + Dairy (1C + 1B). Load carrying through head load was found extensively performed by the women of FS3 followed by FS4: Horticulture + Crop + Dairy (1C+1B) and FS2 respectively. Chopper (hand tool) for chaff cutting, winnowing through natural wind, power operated winnowing without safety gadgets was performed in FS4 (33%), FS3 (22.8%) and FS4 (17%) respectively by family female workers. Threshing through hand beating was maximally performed by FS2 (81%) as hired female labour. Work involvement in farming system studies shows that female workers (family and hired) of FS3 contributed maximum (44.7%) followed by FS1 (41.5%). Also, the women participation index on drudgery prone activities was found highest amongst female workers (family and hired) of FS3 (87.8%) followed by FS1 (83.21%). The results indicate that FS3 may be tagged as sensitive farming system with respect to maximum number of female headed households contributing maximum work and hardships followed by FS1.

Abstract:
The foundation of any smart city requires an innovative and robust communication infrastructure. Many research communities envision free-space optical communication (FSO) as a promising backbone technology for the services and applications provided by such cities. However, the channel through which the FSO signal travels is the atmosphere. Therefore, the FSO performance is limited by the local weather conditions. The variation in meteorological variables leads to variations of the refractive index along the transmission path. These index inhomogeneities (i.e., atmospheric turbulence) can significantly degrade the performance of FSO systems. Thus, a practical implementation of the FSO link must carefully consider the atmospheric turbulence effect. This paper aims to investigate the feasibility of FSO communication for NEOM, a promising smart city in Saudi Arabia. We study the effect of weather conditions on FSO links using the micrometeorology model, taking into account actual weather data. The FSO performance in winter and summer was compared in terms of the bit error rate, signal-to-noise ratio (SNR), link availability, and transmission distance. The study shows that the atmospheric turbulence strength is moderate and strong in winter and summer, respectively. The temperature has the biggest impact on the FSO system when compared to the other meteorological elements included in this study. Furthermore, at transmission distances less than 300 m, atmospheric turbulence does not significantly affect the FSO for the operating wavelength of 1550 nm. Furthermore, it has been shown that at transmission distances greater than 300 m, the SNR in summer is more than 18% higher than in winter. The findings of this research enable understanding of the effect of turbulence caused by NEOM weather on the FSO link, thus assisting engineers in establishing a reliable FSO backbone link by adjusting the relevant parameters.

Abstract:
The catalytic ozonation of diclofenac (DCF) with iron silicate-loaded pumice (FSO/PMC) in aqueous solution was investigated. FSO/PMC was synthesized by a co-precipitation–impregnation method and characterized using scanning electron microscope, N2 adsorption–desorption, X-ray fluorescence, and pHpzc measurements. Results showed that the FSO/PMC/O3 process obviously improved total organic carbon (TOC) removal efficiency from 32.3% (using sole ozonation) to 73.3% in 60 min. DCF mineralization in various oxidation processes was found to follow a two-stage pseudo-first-order kinetics. The presence of FSO/PMC effectively improved the mass transfer of ozone from gas to liquid phase and increased the efficiency of ozone decomposition, which results in the formation of •OH radicals. The ozonation of DCF generated large amounts of the ozone-refractory carboxylic acids, and these compounds were found to be continuously removed in the FSO/PMC/O3 process due to the catalytic activity of FSO/PMC. The synergetic effect between ozonation and FSO/PMC adsorption indicated that FSO/PMC is a promising catalyst for the ozonation process.

Abstract:
Acetaminophen (AAP) is a commonly analgesic found in numerous non-prescription pharmaceuticals. High dose and chronic ingestion of AAP caused renal toxicity. This study is designed to assess the possible nephroprotective role of flaxseed oil (FSO) in male rats. Nephrotoxicity was induced in rats via ingested a single dose of AAP (3 g/kg). Five groups of rats were used; Control, AAP, FSO (1.5 ml/kg) + AAP, FSO (3 ml/kg) + AAP, and FSO (4.5 ml/kg) + AAP. Rats were received orally FSO for 30 days and at the 30th day received AAP 1 h before FSO. Serum renal function indices were determined. Also, antioxidants, oxidative stress, and pro-inflammatory cytokines indices were measured in serum. Ingestion of FSO (3 and 4.5 ml/kg) prior to AAP intoxication significantly decreased AAP-induced nephrotoxicity as evidenced by significant decrease in renal functions relative to the AAP group. Prevented the oxidative stress as evidenced by significant increases in SOD and GSH levels, concurrent with a significant decline in MDA level. Besides, there were significant decreases in IL-1α and TNF-α relative to the AAP group. FSO (3 and 4.5 ml/kg) preserved the renal parenchyma, glomerulus and tubules histological features induced by AAP. FSO (4.5 ml/kg) was markedly the most effective dose relative to the two other doses. In conclusion, FSO protects AAP-induced renal toxicity in a dose dependent manner via its potent antioxidant and anti-inflammatory activities.

Abstract:
Free space optical (FSO) communication systems provide wireless line of sight connectivity in the unlicensed spectrum, and wireless optical communication achieves higher data rates compared to their radio frequency (RF) counterparts. FSO systems are particularly attractive for last mile access problem by bridging fiber optic backbone connectivity to RF access networks. To cope with this practical deployment scenario, there has been increasing attention to the so-called dual-hop (RF/FSO) systems where RF transmission is used at a hop followed by FSO transmission to another. In this article, we study the performance of cooperative transmission systems using a mixed RF-FSO DF (decode and forward) relay using error-correcting codes including QC-LDPC codes at the relay level. The FSO link is modeled by the gamma-gamma distribution, and the RF link is modeled by the Additive White Gaussian Noise (AWGN) model. Another innovation in this article is the use of cooperative systems using a mixed FSO/RF DF relay using quasicyclic low-density parity check (QC-LDPC) codes at the relay level. We also use the space-coupled low-density parity check (SC-LDPC) codes on the same scheme to show its importance in cooperative optical transmission but also in hybrid RF/FSO transmission. The latter will be compared with QC-LDPC codes. The use of mixed RF/FSO cooperative transmission systems can improve the reliability and transmission of information in networks. The results demonstrate an improvement in the performance of the cooperative RF/FSO DF system based on QC-LDPC and SC-LDPC codes compared to RF/FSO systems without the use of codes, but also to the DF systems proposed in the existing literature.

Abstract:
Two of the most common elevator algorithms, FS4 and FSO, are discussed in this thesis. Their pros and cons regarding passenger waiting time and energy consumption are compared to find which of the algorithms perform best and what factors affect this. These topics are of interest for owners of modern building.By developing a simulation program the behavior of elevators controlled by these algorithms were simulated. Passenger pattern in the simulation was meant to emulate the pattern that occurs in office buildings at lunch hour.The conclusion is that due to differences in sector usage and specific rules for each algorithm they have different strengths concerning waiting time and energy consumption, but overall the FS4 is the stronger choice.

Abstract:
In this thesis, we propose a novel architecture for hybrid radio frequency (RF)/free–space optics (FSO) wireless systems. Hybrid RF/FSO systems are attractive since the RF and FSO sub–systems are affected differently by weather and fading phenomena. We give a thorough introduction to the RF and FSO technology, respectively. The state of the art of hybrid RF/FSO systems is reviewed. We show that a hybrid system robust to different weather conditions is obtained by joint bit–interleaved coded modulation (BICM) of the bit streams transmitted over the RF and FSO sub–channels. An asymptotic performance analysis reveals that a properly designed convolutional code can exploit the diversity offered by the independent sub–channels. Furthermore, we develop code design and power assignment criteria and provide an efficient code search procedure. The cut–off rate of the proposed hybrid system is also derived and compared to that of hybrid systems with perfect channel state information at the transmitter. Simulation results show that hybrid RF/FSO systems with BICM outperform previously proposed hybrid systems employing a simple repetition code and selection diversity.

We investigate pulse position modulation (PPM) and multipulse PPM (MPPM) for free space op- tical channels using bit interleaved coded modulation with iterative decoding. Data bits are first encoded by using a non recursive convolutional code and the coded bits after an interleaver are modulated before transmission. Iterative decoding is performed at the receiver. Optimized mapping is designed for MPPM. A genetic algorithm is used to find the optimized mapping for MPPM. Our simulation results show that a significant improvement in the error performance can be achieved by using optimized mapping and iterative decoding at the receiver.

Cieľom práce je nájsť optimálne rozloženie optickej intezity v rovine vysielacej apertúry, ktoré bude minimálne ovplyvnené apertúrou vysielača a atmosférickými turbulenciami. Za účelom analýzy šírenia optickej vlny atmosférou bola využitá simulácia založená na metóde Split-Step. Šírenie Flattened Gaussian zväzku bolo analyzované pre režim slabých a stredných turbulencií.

Abstract:
Free space optical (FSO) communication uses visible or infrared (IR) wavelengths to broadcast high-speed data wirelessly through the atmospheric channel. The performance of FSO communications is mainly dependent on the unpredictable atmospheric channel such as fog, smoke and temperature dependent turbulence. However, as the real outdoor atmosphere (ROA) is time varying and heterogeneous in nature as well as depending on the magnitude and intensity of different weather conditions, carrying out a proper link assessment under specific weather conditions becomes a challenging task. Investigation and modelling the ROA under diverse atmospheric conditions is still a great challenge in FSO communications. Hence a dedicated indoor atmospheric chamber is designed and built to produce controlled atmosphere as necessary to mimic the ROA as closely as possible. The experimental results indicate that the fog attenuation is wavelength dependent for all visibility V ranges, which contradicts the Kim model for V < 0.5 km. The obtained result validates that Kim model needs to be revised for V < 0.5 km in order to correctly predict the wavelength dependent fog attenuation. Also, there are no experimental data and empirical model available for FSO links in diverse smoke conditions, which are common in urban areas. Therefore, a new empirical model is proposed to evaluate the wavelength dependent fog and smoke attenuation by reconsidering the q value as a function of wavelength rather than visibility. The BER performance of an FSO system is theoretically and experimentally evaluated for OOK- NRZ, OOK-RZ and 4-PPM formats for Ethernet line data-rates from light to dense fog conditions. A BER of 10-6 (Q-factor ≈ 4.7) is achieved at dense fog (transmittance, T = 0.33) condition using 4-PPM than OOK-NRZ and OOK-RZ modulation schemes due to its high peak-to-average power ratio albeit at the expense of doubling the bandwidth. The effects of fog on OOK-NRZ, 4-PAM and BPSK are also experimentally investigated. In comparison to 4-PAM and OOK-NRZ signals, the BPSK modulation signalling format is more robust against the effects of fog. Moreover, the effects of using different average transmitted optical communication powers Popton the T and the received Q-factor using the OOK-NRZ modulation scheme are also investigated for light and dense fog conditions. The results show that for an FSO system operating at a Q-factor of 4.7 (for BER = 10-6), the required Q-factor is achieved at T of 48% under the thick fog condition by increasing Popt to 1.07 dBm, whereas the values of T are 55% and ~70% for the transmit power of 0.56 dBm and -0.7 dBm, respectively. The experimental characterisation and investigation of the atmospheric turbulence effect on the Ethernet and Fast-Ethernet FSO link is reported using different modulation schemes. The experiment is carried out in a controlled laboratory environment where turbulence is generated in a dedicated indoor atmospheric chamber. The atmospheric chamber is calibrated to mimic an outdoor turbulence conditions and the measured data are verified against the theoretical predictions. The experiment also demonstrates methods to control the turbulence levels and determine the equivalence between the indoor and outdoor FSO links. The results show that the connectivity of Ethernet and Fast-Ethernet links are highly sensitive to atmospheric turbulence. The results also show that the BPSK and OOK-NRZ modulation signalling formats are more robust against the weak atmospheric turbulence conditions than PAM signal.

Resumo: Os objetivos centrais do presente trabalho foram a montagem de um link de comunicação óptica no espaço livre (FSO) e a posterior inserção de um feixe (nãodifrativo) de Bessel no enlace. Após uma breve revisão dos conceitos e limitações envolvidos no funcionamento dos sistemas FSO, construímos um enlace óptico chegando a uma distância de 50 metros a um custo muito reduzido. Na tentativa de diminuir o eventual impacto causado pela difração do feixe óptico, propusemos o uso de feixes não difrativos para realizar o link. Assim, após um estudo das características básicas do feixe nãodifrativo de Bessel e de sua geração experimental, realizamos sua inserção num enlace óptico de curta distância com o propósito de demonstrar a real possibilidade de uso desses feixes em comunicações ópticas no espaço livre

After a brief review of the concepts about the operation and limitations of FSO systems, we build an optical link through a distance of 50 meters at a much reduced cost. Attempting to reduce the possible impact caused by the optical beam diffraction, and scattering we have proposed the use of nondiffracting beams to perform the link. In this way, after studying the basic characteristics of nondiffracting Bessel beams and their experimental generation, we implement their insertion in a short-distance optical link in order to demonstrate the real possibility of using these beams in free space optical communications

Research, IFF. Small and Micro Food Business Operator (FBO) Tracking Survey: Wave 3 2021 - Technical Report. Food Standards Agency, May 2022. http://dx.doi.org/10.46756/sci.fsa.sty242.

Full text
Abstract:
The Food Standards Agency (FSA) has been tracking small and micro Food Business Operator (FBO) attitudes towards food-related topics, and trust in the FSA and food system, since 2018. This has helped inform engagement and intervention activity targeted at businesses with fewer than 50 staff. The survey was initially developed to assess the perceived impact of changes as a result of the UK’s exit from the European Union (EU), and the Achieving Business Compliance (ABC) programme, which aims to modernise the regulation of food businesses in England, Wales and Northern Ireland. Since then, it has evolved to regularly track small and micro FBO views on a range of subjects. In 2021, the third wave of the annual tracking survey was carried out, with the following aims: To gain insight, and understand the implications of the EU Exit on small and micro enterprises To ‘unpack’ attitudes towards regulation and deepen insights and knowledge of small and micro enterprises, including with regards to the FSA’s ABC priority To measure trust in the FSA and extent to which FSA is considered a modern, accountable regulator All fieldwork for wave 3 was carried out by IFF Research, an independent market research company, commission by FSA. This paper outlines the methodological approach taken for wave 3 of the research, including sampling; feasibility testing; pilot and mainstage fieldwork; response rates; and weighting.

UK, Ipsos. Survey of public attitudes towards precision breeding. Food Standards Agency, October 2022. http://dx.doi.org/10.46756/sci.fsa.ouv127.

Full text
Abstract:
The Genetic Technology (Precision Breeding) Bill is currently going through Parliament. Although this bill is ‘England only’ and food and feed safety and hygiene is a devolved issue, the Food Standards Agency (FSA) will introduce a separate regulatory framework for precision bred organisms (PBOs), should the Bill become law. The FSA will also work with stakeholders in Scotland, Wales and Northern Ireland to ensure consumers’ interests are protected in relation to PBOs. The FSA / Food Standard Scotland (FSS) is science and evidence led. In August 2022, the FSA and FSS commissioned Ipsos UK to conduct a two-phase social research project on precision breeding. Phase One, now complete, involved a survey of 4,177 UK residents with robust samples in each UK nation to allow comparisons between and within nations. Phase Two, scheduled to start in September 2022 and report in early 2023, will comprise a series of Citizens’ Forums in England, Wales and Northern Ireland(footnote 1). The overall aims of this project are to: explore consumer attitudes towards precision breeding gather consumer views on the FSA’s proposed regulatory framework understand consumer information needs inform how to communicate with consumers about precision breeding. This document presents interim findings for this project, reporting descriptive data from Phase One. Phase One’s core aims were to provide a snapshot of consumers’ awareness and self-assessed knowledge of precision breeding, its perceived acceptability, risks and benefits, and consumer appetite for information about this production method. These data show that awareness of precision breeding is very low, something which should be borne in mind when considering these findings. While these data reveal that there is a general openness to trying precision bred foods across the UK, with more people anticipating benefits than disbenefits from the use of precision breeding, there is a large degree of uncertainty about what impact precision bred foods may have on the different parts of the food system. This is reflected in the relatively large proportions of people taking a neutral stance or indicating they do not know enough to answer survey questions and in the strong appetite expressed for information about precision breeding to be provided. The next phase of this project will be essential for the FSA’s ability to interpret these findings’ implications, and to understand what is informing consumers’ views. The purpose of Phase One has always been to let the FSA know ‘what’ consumers think about precision breeding; Phase Two’s purpose is to build our understanding ‘why’ they think it. This will allow the FSA to develop a more nuanced understanding of consumers’ needs and incorporate this into the design of the future regulatory framework and any engagement with consumers on precision breeding. FSS will be carrying out further research in Scotland.

King, Lucy. FSA Consumer segmentation. Food Standards Agency, September 2021. http://dx.doi.org/10.46756/sci.fsa.bmo506.

Full text
Abstract:
For our audiences, it is important to find out how their attitudes and behaviours relating to food safety differ, in order to understand who is more likely to take food safety risks and in what context. This is essential for effective communications and helps us to shape food safety policy. The audiences in these documents have been created using attitudinal and behavioural segmentation that categorises people based on their attitudes to food and their reported hygiene and food safety behaviours.

Bogdan, Alex, and Nikki Soo. Survey of consumer practices with respect to coated frozen chicken products. Food Standards Agency, June 2021. http://dx.doi.org/10.46756/sci.fsa.hrb725.

Full text
Abstract:
The Food Standards Agency (FSA) is investigating a spike in Salmonella cases in the UK linked to the consumption of coated frozen chicken products. In March 2021, FSA, in collaboration with Food Standards Scotland (FSS) commissioned Ipsos MORI to conduct an online survey in order to identify consumer behaviours which could increase their risk to foodborne disease. The key research questions were: •Which consumers are purchasing coated frozen chicken products? •How do consumers store and cook these products? •Do consumers follow packaging instructions when cooking and storing these products?•Are consumers putting themselves at risk of Salmonellain the way they, store, cook and handle these products? •Do consumers take appropriate action to protect themselves from risk by washing their hands, and avoiding cross-contamination when handling these products? •Do children (aged 12 or under) or teenagers (aged 13-15) handle and cook these products?
