Abstract A novel cost-effective wavelength shifter is suggested in this paper. This paper shows how to shift signals in the mm-wave area using a frequency shifter. Due to stimulated Brillouin scattering in optical fibre, the proposed approach produces a single sideband signal without the carrier signal. When compared to SSB-SC transmissions, the bandwidth efficiency of double sideband signals is lower. Because it employs an optical fibre with a performance degrading condition such as SBS as an application, the frequency shifter is entirely optical. The theory of Gain and Loss Spectrum of SBS within optical fibre is utilised to minimise the upshifted frequency component and boost the low shifter frequency component in order to generate improved carrier power and single sideband. The SBS phenomenon produces a single sideband, which is advantageous in advanced modulation systems and consumes less bandwidth. It’s worth noting that the SSB-SC signal may be generated using any optical approach, and the proposed work eliminates the need for non-optical components like 90-degree hybrid couplers. SSB-SC signals are capable of combating pulse broadening difficulties and have the ability to operate at terahertz frequencies. Transmission of an SSB-SC signal is also shown to validate the performance of the produced signal. Furthermore, the Q factor of SSB-SC, SSB with carrier, DSB-SC, and DSB with carrier signals is studied at various connection lengths.

AbstractObjective:To test whether point-of-sale (POS) information about the nutrition content of sugar-sweetened beverages (SSB) promotes healthier drink choices among teenagers, and explore whether POS intervention effects vary based on prior exposure to a sugary drink public health campaign (13 Cancers).Design:Between-subjects online experiment with three POS signage conditions: no signage (control); sugar content (SC) and Health Star Rating (HSR). Participants viewed their assigned POS sign alone, then alongside a drinks product display and chose which drink they would buy. Perceptions of various drink products and campaign recall were assessed.Setting:Australia.Participants:Adolescents aged 13–17 years (n 925) recruited via an online panel.Results:POS signs did not promote a significant reduction in preference for SSB (cf. control condition). Cognitive and emotional responses to POS signs were strongest for the SC sign, which was rated higher than the HSR sign on various perceived effectiveness measures. Participants who saw the SC sign rated SSB as less healthy (cf. control condition) and were more likely to accurately estimate the number of teaspoons of sugar in soft drink (cf. HSR sign and control conditions). There was no significant interaction between prior exposure to the 13 Cancers campaign and POS signage condition regarding preferences for and perceptions of SSB.Conclusions:SSB POS interventions may not have the desired effect on adolescents’ drink preferences. Testing SSB POS signs in real-world retail settings is needed to determine whether positive educational impacts extend to promoting healthier drink purchases and reduced SSB consumption among teenagers.

Background: Sorghum-Soy Blend (SSB) and Sorghum-Cowpea Blend (SCB) fortified blended food aid porridge products were developed as alternatives to Corn-Soy Blend Plus (CSB+) and Super Cereal Plus (SC+), the most widely used fortified blended food aid products. However, the cost and nutrient cost-effectiveness of these products procured from different geographical areas have not been determined. Objective: The objective of this study is to determine the nutrient cost-effectiveness of SSB and SCB compared to existing fortified blended foods. Methods: Nutritional data as well as ingredient, processing, and transportation cost for SSB, SCB, and existing fortified blended foods were compiled. Using the omega value, the ratio of the fortified blended food’s Nutrient Value Score to the total cost of the fortified blended food divided by an identical ratio of a different fortified blended food or the same fortified blended food produced in a different country and the nutrient cost-effectiveness of each of the fortified blended foods procured in the United States and several African countries were determined. Results: Both CSB+ and SC+ are less expensive than SSB and SCB, but they also have lower Nutrient Value Scores of 7.7 and 8.6, respectively. However, the omega values of CSB+ and SC+ are all above 1 when compared to SSB and SCB, suggesting that the existing fortified blended foods are more nutrient cost-effective. Conclusions: Comparing the nutrient cost-effectiveness of various food aid products could provide valuable information to food aid agencies prior to making procurement decisions.

Cable termination fault is one of the most important problems for high voltage underground cable lines (HVUCL). Harmonic current (HC) and the sheath current (SC) are causes of cable termination faults of HVUCL. The sheath voltage (SV) of cable increases due to SC and HC also. So, the electroshock risk for human occurs. In this study, cable termination faults are examined for long HVUCL that is connected to electric network with high harmonic distortion rate. In literature, solid bonding (SB) and sectional solid bonding (SSB) methods are used to reduce harmonic distortion rate and SC effect in HVUCL. However, when SB and SSB methods are used for bonding of long HVUCL, harmonic distortion limit and touch voltage limit are exceeded. Therefore, the modified SSB (MSSB) method is developed for bonding of long HVUCL. SV of HVUCL should be known to use MSSB for bonding of long HVUCL. Then SV of HVUCL is forecasted by using artificial neural network and hybrid artificial neural networks (HANN) before the long HVUCL is installed. MSSB parameters should be optimized, so that optimization methods are used for optimization of MSSB and HANN. When MSSB method is used for bonding of long HVUCL, harmonic distortion limit and touch voltage limit are not exceeded under high harmonic distortion conditions.

Makalah ini merupakan laporan hasil percobaan rancang bangun radio transceiver single side-band (SSB) dengan metode bi-directional. Skema radio pemancar-penerima (transceiver) single side-band (SSB) dua arah (bi-directional) dirancang dengan sistem penerima konversi tunggal (single conversion). Aplikasi bi-directional dalam skema ini bertujuan untuk menyederhanakan rangkaian transceiver SSB. Metode yang digunakan pada radio transceiver SSB bi-directional yaitu menggunakan beberapa bagian rangkaian secara bersama seperti (a) rangkaian balance modulator (BM) sekaligus sebagai demodulator SSB, (b) filter intermediate frequency (IF filter) untuk filter pemancar dan penerima, dan mixer. Sistem ini menggunakan direct digital synthesizer (DDS) sebagai variable frequency oscillator (VFO) dan menggunakan rangkaian osilator kristal sebagai beat frequency oscillator (BFO). Filter IF menggunakan 4 (empat) buah kristal identik agar diperoleh lebar pita frekuensi 3 kHz sebagaimana yang dipersyaratkan pada sinyal SSB. Rangkaian mixer menggunakan empat buah diode identik dan pada rangkaian balance modulator digunakan dua buah diode identic. Pada sistem ini, rangkaian BM digunakan sebagai pembangkit sinyal DSB-SC, dimanfaatkan pula sebagai demodulator SSB . Penalaan (tuning) frekuensi dilakukan oleh sebuah lokal osilator yang dibuat dari rangkaian Direct-Digital Synthesizer (DDS). Pengaturan skala perubahan frekuensi osilator DDS dapat dilakukan mulai dari skala 1 Hz sampai 1 MHz.

Sugar-Sweetened Beverage (SSBs) consumption has risen in early life and it is plausible that it might increase children’s risk of allergies. In this paper, we analyzed the association of SSB consumption with allergies in children’s second year of life. This study analyzed data from a São Luís BRISA prenatal cohort in the follow-up of children (n = 1144) in their second year of life. Allergy Traits were a latent variable deduced from medical diagnoses of allergic rhinitis, atopic dermatitis, and food allergies. SSBs were investigated as a percentage of daily calories based on 24 h recalls, including industrialized fruit juices, soft drinks, and ready-made chocolate milk. Other variables analyzed were socioeconomic status, age, body mass index z-score, episodes of diarrhea, and breastfeeding. Our finds were that higher consumption of daily calories from SSBs was associated with higher Allergy Trait values (SC = 0.174; p = 0.025); older age (SC = −0.181; p = 0.030) was associated with lower Allergy Trait values; and episodes of diarrhea were correlated with Allergy Traits (SC = 0.287; p = 0.015). SSB exposure was associated with Allergy Traits in children’s second year of life; thus, abstaining from these beverages may also confer additional advantages in curtailing allergic diseases during early childhood.

An optoelectronic oscillator (OEO) based on series-coupled double recirculating delay lines (SC-DRDLs) is analyzed and experimentally demonstrated. The SC-DRDLs composed by the coupling cascade of two RDLs, which the free spectral range (FSR) is least common multiple of the two RDLs’ FSR, and then the large FSR can be obtained by properly setting the loop lengths of two RDLs. By consociation with the dual loops system between the dual output of the SC-DRDLs and PBS, the high sidemode suppression performance can be achieved. Meantime, the incoherence of the SC-DRDLs can be performed by using an amplified spontaneous emission (ASE) broadband laser source. An experiment is carried out. A microwave signal with high spectral purity, long-term stability, low single-sideband (SSB) phase noise is generated.

A Microwave frequency channelization scheme has been proposed and demonstrated with the help of Optical frequency comb, Mach-zhender modulator, Fabry Parot Filter, Optical Demux. In the proposed channelizer an incoming wideband is multicast by Optical Frequency comb, spectrally sliced by Fabry perot filter and physically separated by demux. In comparison to previous proposals we have used OFC for channelization to have more uniform, noise immune and simple channelization. We have used SSB-SC Modulation instead of DSB-SC modulation so that we can channelize our signal to 40-50 GHz range than 19.5 proposed in previous paper. As precision of measurement and range to which we can process our Microwave signal depends on number of equally spaced line, we have designed a 36 line OFC and used in our proposal which is much greater than 6 lines used by previous proposal. As an illustration only we have used only 15 line OFC in our experiment but we can also use 36 line OFC wherever required. As an application multiple frequencies can be processed and measured simultaneously so that our processing is fast, efficient and easy to handle by our premature electronics devices.
