Forecasting Methods of Battery Charge and Discharge Current Profile for LEO Satellites

The orbital characteristics of low Earth orbit (LEO) satellite systems prevent continuous monitoring because ground access time is limited. For this reason, the development of simulators for predicting satellite states for the entire orbit is required. Power-related prediction is one of the important LEO satellite simulations because it is directly related to the lifespan and mission of the satellite. Accurate predictions of the charge and discharge current of a power system’s battery are essential for fault management design, mission design, and expansion of LEO satellites. However, it is difficult to accurately predict the battery power demand and charging of LEO satellites because they have nonlinear characteristics that depend on the satellite’s attitude, season, orbit, mission, and operating period. Therefore, this paper proposes a novel battery charge and discharge current prediction technique using the bidirectional long short-term memory (Bi-LSTM) model for the development of a LEO satellite power simulator. The prediction performance is demonstrated by applying the proposed technique to the KOM-SAT-3A and KOMSAT-5 satellites operating in real orbits. As a result, the prediction accuracy of the proposed Bi-LSTM shows root mean square error (RMSE) within 2.3 A, and the prediction error well outperforms the most recent the probability-based SARIMA model.
Image Super-Resolution using Modified Residual Network

—The applications of image super-resolution techniques in recent years has increased noticeably. From a video playback on high-resolution LED TVs to Satellite Imaging all use image upscaling. The main purpose of image upscaling is to obtain high-resolution images from low-resolution images without any extra information except the input images, and these upscaled images should keep satisfactory visual qualities and natural textures. The most popular image upscaling algorithms are interpolation methods. But, in recent times Neural Network is used for upscaling the images more accurately. We propose a Neural Network based method to upscale the lower resolution image into a higher resolution image and improve the image quality without losing much detail in the process. We designed an architecture based on the modiﬁcation of residual learning method which generates the high resolution image faster with some blurry effects which is removed in the post processing step. The experiments conducted using the proposed method shows that even with much fewer parameters and operations due to group convolution, this model achieves comparable results to other deep learning based methods.
Does artificial viscosity destroy prompt type-II supernova explosions?

We apply two different methods for the numerical treatment of the hydrodynamical equations to the problem of stellar core collapse in one dimension, starting the simulations with the same initial model and using the same equation of state. We follow the collapse with a standard Lagrangian finite difference scheme with artificial viscosity and compare it with a second order Godunov-type scheme (PPM), which works in Eulerian coordinates. Different from Marti et al. (1990) our results demonstrate that with a careful use of an up-to-date tensor form for the artificial viscosity the results of both codes are in excellent agreement
Behavioral Disorder in Children Attending Tertiary Care Teaching Hospital: A Prospective Observational Study

Aim and Objective : The present study was undertaken to determine the incidence of behavioral problems in pediatric patients and correlate with socio-demographic profile, parent’s education, parental illness and family structure. Also, to study impact of behavioral problem in due form of social impairment, distress, burden to others and chronicity as perceived by parents. Method: Total 600 children (age 5-12 years) from pediatric outpatient or inpatient department were screened by using Strength and Difficulty Questionnaire (SDQ). Interview of parent or guardian include questionnaire was done to assess the behavioral problems. Patients identified to have behavioral problems was referred to the psychiatry department for further evaluation and management and then followed for 3 months and outcome was recorded. Results: The incidence of behavioral disorder in outdoor patients was 7.56% and in indoor patients was 6.67%. In both the outdoor and indoor patients analysis behavioral disorders were showed strong association with social impairment (OPD=82.35%, IPD=70%), family distress (OPD=85.29%, IPD=70%), burden to others (OPD=79.41%, IPD=60%) and chronicity (OPD=61.76%, IPD=60%). There was no correlation found between behavioral disorders and parental education, family structure in both indoor and outdoor patients’ analysis. Among indoor patients, 46.67% needed pharmacological treatment, 20% required counseling, 13.33% were given special education, and about 20% patient did not require any treatment. In outdoor patients analysis 19 patients improved markedly and 3 improved minimally, 35.29% patients did not show any improvement till 3 months follow up. Conclusion: Early reorganization and prompt intervention can improve outcome of patients with behavioral problems. This would help in reducing morbidity associated with behavioral disorders.
Prevalence and antibiotic resistant salmonella in retail broiler chickens in Ibadan, Oyo State, Nigeria

Poultry meat has been identified as one of the principal food-borne sources of salmonella. In this study, the prevalence of contamination with Salmonella spp. of broiler carcasses sold for human consumption at retail markets in Ibadan metropolis were identified and confirmed by cultural and molecular methods, susceptibility of the isolates to commonly used antibiotics was also determined. Two hundred samples were randomly collected from broiler carcasses from selected retail markets in Ibadan metropolis. The presence of salmonella spp. in the samples was determined after pre-enrichment, enrichment and culture on selective agar. Biochemical tests and molecular identification were further carried out to confirm the isolates. Polymerase Chain Reaction (PCR) assays was carried out using the invA specific primers for the detection of Salmonella spp. The confirmed isolates were then subjected to antibiotic sensitivity test using the disc diffusion method. Cultural isolation and biochemical characterization of retail broiler carcasses yielded 25.5% prevalence while molecular identification (PCR) yielded 4% prevalence. Antibiotic sensitivity test showed 100% resistance to Cefixime, Celflozidime and Oxytetracycline. Also, a high percentage resistance of Gentamicin (87.5%) and Cefuroxime (75%) to the isolated Salmonella spp. was observed. The prevalence of salmonella spp. from broiler chickens sold for consumption in the selected retail markets in Ibadan metropolis obtained using the molecular identification (PCR) method- 4% should be considered the true picture of the prevalence. Therefore, in order to provide a more accurate profile of the prevalence of Salmonella spp. in broiler carcasses, it is pertinent to use invA gene specific PCR method that could be considered as an appropriate alternative (Standard) to conventional culture method. The high percentage of resistance to the commonly used antibiotics obtained in this study could also be attributed to the irrational, persistent, unrestricted and uncontrolled use of these antibiotics in poultry production as curative; prophylactic or growth promoter in the study area. This study established the need to improve on hygiene at the point of slaughtering and dressing of broiler chickens so as to eradicate Salmonella spp. from poultry markets. Also, the need for proper use of antibiotics to increase bacteria sensitivity to antibiotic for better results when needed was emphasized.
EliScholar – A Digital Platform for Scholarly Publishing at Yale EliScholar – A Digital Platform for Scholarly Publishing at Yale Mothers’ Social Networks and Socioeconomic Gradients of Mothers’ Social Networks and Socioeconomic Gradients of Isolation Isolation

Social connections are fundamental to human wellbeing. This paper examines the social networks of young married women in rural Odisha, India. This is a group, for whom highly-gendered norms around marriage, mobility, and work are likely to shape opportunities to form and maintain meaningful ties with other women. We track the social networks of 2,170 mothers over four years, and find a high degree of isolation. Wealthier women and women more-advantaged castes have smaller social networks than their less-advantaged peers. These gradients are primarily driven by the fact that more-advantaged women are less likely to know other women within their same socioeconomic group than are less-advantaged women are. There exists strong homophily by socioeconomic status that is symmetric across socioeconomic groups. Mediation analysis shows that SES differences in social isolation are strongly associated to caste, ownership of toilets and distance. Further research should investigate the formation and role of female networks. women’s propensities to have social connections within their SES group; second, SES-differences in women’s propensities to have ties across SES groups (i.e. differences in the degree of homophily); and third, the SES-composition of villages coupled with the initial degree of homophily. Our data suggest that the first component is the chief driver of both the caste/tribe and the wealth gradients: higher-SES women are substantially less likely to know the other higher-SES women in their village than lower-SES women are to know the other lower-SES women. The negative relationship between wealth status and connections also holds within caste/tribe groups. Social ties across SES-groups are less common than those within groups, indicating substantial
Improvement of In vitro Digestibility and Gas Production of Sugar Palm Peel Silage using Fermented Napier Grass Juice

The objective of this study was to improve sugar palm peel silage using fermented Napier grass juice. Fermented Napier grass juice without sugar and with 1% glucose, 1% sucrose, 3% glucose, 3% sucrose, 5% glucose and 5% sucrose were prepared. Results showed that pH values of the fermented juices were 3.94 - 5.72. The highest total sugar content (136.30 mg/ml) was obtained from fermentation with 5% sucrose. In addition, fermentation without sugar gave higher lactic acid bacteria (15.17 × 10 6 cfu/ml) and aerobic bacteria content (19.23 × 10 7 cfu/ml) than other treatments while fermentation with 3% glucose gave the highest yeast and fungi count (22.37 × 10 7 cfu/ml). Therefore, the fermented juice without sugar was further used to improve the fermented sugar palm peel. Sugar palm peel silages without fermented juice and with 1% fermented juice and 1% molasses were prepared. Results showed that adding 1% fermented juice gave the lowest pH at day 7 and 14. Adding 1% molasses resulted in higher crude protein and lower hemicellulose and cellulose contents than other treatments. In vitro dry matter digestibility of samples with 1% fermented juice and 1% molasses at day 7 were significantly higher than sample without fermented juice. Similarly, gas production of sugar palm silages was significantly different among treatment. Gas production of sugar palm peel silages was highest at day 7. Based on the results, it can be concluded that fermented Napier grass juice was suitable for improving sugar palm peel silage.
An SiC MOSFET Based Three-Phase ZVS Inverter Employing Variable Switching Frequency Space Vector PWM Control

In this paper, a variable switching frequency space vector pulsewidth modulation control is proposed. It is used to achieve zero voltage switching (ZVS) for a three-phase grid-connected voltage source inverter with unity power factor. A wide range of ZVS can be realized without any additional sensors, auxiliary circuits, or current zero crossing detection circuits. The switching frequency can be easily calculated by a digital controller. The frequency variation range in a line cycle is only about 1.5 times at any specific load. An LCL filter is used to attenuate the high current ripples at the inverter side, and active damping is adopted to avoid the resonance and reduce the filter power loss. The switching loss can be significantly reduced by using silicon carbide mosfets so that the conversion efficiency is high. The power density can also be improved due to the high switching frequency and the low inductance value of the filter. The operating principle, design considerations, and loss analyses are discussed in detail. A 3.5-kW simulation and experimental prototype interfacing a 350–400-V dc with a three-phase 110-V ac grid is developed to verify the performance of the proposed control strategy.
Systemic NK Cell Development Adipocyte IL-15 Regulates Local and

NK cell development and homeostasis require IL-15 produced by both hematopoietic and parenchymal cells. Certain hematopoietic IL-15 sources, such as macrophages and dendritic cells, are known, whereas the source of parenchymal IL-15 remains elusive. Using two types of adipocyte-speciﬁc Il15 2 / 2 mice, we identiﬁed adipocytes as a parenchymal IL-15 source that supported NK cell development nonredundantly. Both adipocyte-speciﬁc Il15 2 / 2 mice showed reduced IL-15 production speciﬁcally in the adipose tissue but impaired NK cell development in the spleen and liver in addition to the adipose tissue. We also found that the adipose tissue harbored NK progenitors as other niches (e.g. spleen) for NK cell development, and that NK cells derived from transplanted adipose tissue populated the recipient’s spleen and liver. These ﬁndings suggest that adipocyte IL-15 contributes to systemic NK cell development by supporting NK cell development in the adipose tissue, which serves as a source of NK cells for other organs. The Journal of Immunology , 2014, 193: 000–000. → WT WT → WT chimeras, hematopoietic IL15 deﬁciency a 60–75% NK cell reduction in the BM, SP, and LV, as well as a 33% reduction in the EPI 1). Comparing WT → KO and KO → KO chimeras, hematopoietic IL-15 restored NK cells in a KO environment to . 80% of the WT → WT level in the BM and SP but only to 24% of the WT → WT level in the LV and EPI. These results reveal a difference in the dependency on hematopoietic IL-15 for NK cell homeostasis among different organs (i.e., BM, SP, and LV depend more on hematopoietic IL-15 in comparison with EPI). Also, the lower NK cell reduction in EPI of KO → WT chimeras compared with the other organs suggests a more prominent role for parenchymal IL-15 in supporting EPI NK cell homeostasis. By comparing WT → KO and WT → WT chimeras, we found that the deﬁciency in the recipient IL-15 did not change NK cell homeostasis in the BM; however, it resulted in a 20% reduction in SP and a 76% reduction in LV and EPI. This result indicates that, even in the presence of hematopoietic IL-15, parenchymal IL-15 deﬁciency resulted in a severe reduction in the NK cells in LVand EPI. Taken together, these results indicate that hematopoietic IL-15 preferentially affected NK cell homeostasis in BM and SP, whereas parenchymal IL-15 preferentially affected NK cell homeostasis in the adipose tissue. Both sources of IL-15 affected hepatic NK cell homeostasis equally.
Calculation of Peak to Average Power Ratio of Chu Sequence Using Oversampling

—Highly spectral efficient formats like orthogonal frequency division multiple access suffers from large fluctuations in signal envelope, hence resulting in high peak to average power ratio. Exact measurement of peak to average power ratio is of main concern. And it comes out to be less for discrete orthogonal frequency division multiplexing signal than for continuous one. This paper presents a measurement strategy of peak to average power ratio for the same taking example of a Chu sequence
QUALITY ASSURANCE THROUGH SMART ANGLE MONITORING

There is currently an increasing need for manufacturing companies to achieve flexible, smart and reconfigurable processes in order to address a dynamic and global market (Santos, et al., 2017). Scania being a worldwide truck manufacturer aims to bring its expertise in truck production into an Industry 4.0 based system. The bolt tightening process in the assembly workshop in Scania Oskarshamn presents promising possibilities for implementation of an Industry 4.0 based system. By monitoring angle during the tightening process the system is able to identify deviations occurring in the process or machine (Bickford & Nassar, 1998). An accurate angle interval can be calculated by studying the relationship between torque and angle using the linear regression method (Pennsylvania State University, 2018). In this project the angle intervals have been improved to be able to perform efficient monitoring. The monitoring process creates the possibility for Scania to implement a smart system able to identify, analyze and eliminate deviations in real time production. This is achievable by performing Statistical Process Control (SPC) using the data obtained from production (Gejdoš, 2015). In this project the Process Capability (Cpk) of the tightening process was improved by 365%. An actual smart process should be able to automatically perform the analysis of data, monitor the life of the machine, identify deviations and support the decision making process (Weihrauch, et al., 2018). To achieve this a proposal is presented to connect the tightening machines to a statistical analysis software able to present data efficiently to involved personnel. The improvement of Cpk and analysis of life of the machine presented in this project prove that it is possible to implement the torque control with angle monitoring technique into an Industry 4.0 system.
OPTH_A_268997 3393..3397

Vitreo-retina Research Unit, Department of Ophthalmology, Faculty of Medicine, King Chulalongkorn Memorial Hospital, Chulalongkorn University, Bangkok, Thailand Introduction: The earlier treat stage 3 ROP is more likely to achieve better outcomes. Primary Purpose: To study the unfavorable outcomes and regression after pre-early treatment for ROP. Secondary Purpose: To evaluate the progression and recurrence of ROP requiring retreatment after pre-early treatment for ROP. Patients and Methods: The data were retrieved retrospectively from the medical records of all infants who were screened and treated for ROP from January 2009 to January 2014 at a tertiary care facility. The outcomes measured the following: 1. unfavorable outcomes; 2. regression of ROP; 3. progression of ROP and 4. recurrence of ROP requiring retreatment. We treated all stage 3 ROP in any zone, with or without plus. The study also compared the outcomes between the pre-ETROP and the ETROP subgroups. Results: There were 91 eyes with stage 3 ROP. Of the total of 91 eyes, there were 63 eyes with the pre-ETROP group and 28 eyes of the ETROP group. The unfavorable outcomes after treatment occur 6 eyes from 28 eyes (21.43%) in the ETROP group but no unfavorable outcomes in the pre-ETROP group (P=0.001). The pre-ETROP group who were treated with laser LIO alone had 100% regression, while the ETROP group who were treated with LIO (26 eyes) had 88.46% regression. There were 2 eyes of this group who were treated with a combination of LIO and IVT Bevacizumab. Both of them did not have regression. The recurrence of ROP requiring retreatment occurred in 2 eyes (7.14%) of the ETROP group, but no recurrence in the pre-ETROP group (P=0.092). The progression after treatment occurred in 3 eyes (10.71%) in the ETROP group, but no progression in the pre-ETROP group (P=0.027). Conclusion: The pre-ETROP treatment is useful for reducing unfavorable outcomes and increasing the regression of ROP. Further, the treatment can reduce the recurrence of neovascularization and progression after treatment.
Function by Paramyxovirus Infections Subversion of Pulmonary Dendritic Cell

Lower respiratory tract infections caused by the paramyxoviruses human metapneumovirus (hMPV) and respiratory syncytial virus (RSV) are characterized by short-lasting virus-speciﬁc immunity and often long-term airway morbidity, both of which may be the result of alterations in the Ag-presenting function of the lung which follow these infections. In this study, we investigated whether hMPV and RSV experimental infections alter the phenotype and function of dendritic cell (DC) subsets that are recruited to the lung. Characterization of lung DC trafﬁcking demonstrated a differential recruitment of plasmacytoid DC (pDC), conventional DC (cDC), and IFN-producing killer DC to the lung and draining lymph nodes after hMPV and RSV infection. In vitro infection of lung DC indicated that in pDC, production of IFN- (cid:1) , TNF- (cid:1) , and CCL5 was induced only by hMPV, whereas CCL3 and CCL4 were induced by both viruses. In cDC, a similar repertoire of cytokines was induced by hMPV and RSV, except for IFN- (cid:2) , which was not induced by RSV. The function of lung pDC was altered following hMPV or RSV infection in vivo, as we demonstrated a reduced capacity of lung pDC to produce IFN- (cid:1) as well as other cytokines including IL-6, TNF- (cid:1) , CCL2, CCL3, and CCL4 in response to TLR9 stimulation. Moreover, we observed an impaired capacity of cDC from infected mice to present Ag to CD4 (cid:3) T cells, an effect that lasted beyond the acute phase of infection. Our ﬁndings suggest that acute paramyxovirus infections can alter the long-term immune function of pulmonary DC. The Journal of Immunology, 2009, 182: 3072–3083. of in assays that infected viral Ag (data These ﬁndings that RSV and hMPV infection transiently impairs the ability of pulmonary cDC to present Ag to T
Is J the new K? A failure to replicate Schloss (1981)

According to the marketing literature on sound symbolism, “ K ” is overrepresented as the initial letter in top brand names relative to the frequency with which it appears as the initial letter of words in the English dictionary. However, it is now 35 years since the original study on ‘the K -effect’ was first published and there is, of course, a possibility that trends have changed during that time. Using the Top 200 company names from the Fortune 500 list, and comparing the initial letter frequency to two benchmarks (i.e., the relative frequencies of first letters of words in the English dictionary and Card and Eckler’s [1975] derived letter-frequencies), our analyses (using conservative Bonferroni-corrections) reveal, in fact, that A and J are overrepresented as initial letters in top company names, while S is underrepresented. We argue that the paucity of names starting with the letter K may, therefore, reflect an opportunity for those starting new companies.
