Application of the full thermal model for PV devices

 Efficiency limits of solar cells have been studied since a long time ago giving the maximal theoretical efficiency and capacity current generation for different solar photovoltaic (PV) devices, and at the same time, real solar cells are becoming more efficient. However, some gaps are still remaining to be further improved and get closer to the desired theoretical limit. Therefore, the optimization of the PV efficiency is possible only if the intrinsic and extrinsic losses are well defined, identified, quantified and then mitigated. In this paper, a brief overview of the research evolution of thermal losses is presented. A physical-driven model is used to quantify internal heat sources, optical losses and the actual performance of a PV device. The Full Thermal Model for thermal assessment is presented in detail and applied to a bifacial heterojunction solar cell.
Quantum Ising Models

This report is a summary of a few key techniques for solving quantum Ising models and a summary of well-known mappings between classical Ising models and quantum Ising models. The transfer-matrix formalism will be used to outline a mapping between the D-dimensional classical Ising model and a (D − 1)-dimensional quantum model [3–5]. Furthermore, the quantum Ising model in one-dimension described in the spin-basis will be diagonalized using standard techniques [2, 4] to recover the exact spectrum of its Hamiltonian. Finally, we will investigate the level gap near the critical point of the transverse-field Ising model.
A LINGUISTIC BYPASS OF KEATS’ ‘ODE TO A NIGHTINGALE ’ THROUGH LEXICONS

John Keats’ ‘Ode to a Nightingale’ is considered to be the one of the masterpieces of English like his other odes. It is one of the great odes written by Keats in May 1819. It is a superb poem which was written by the poet while he was staying with his f r end Charles Armitage Brown at Hampstead. For the stylistic study of poetry basically there are six l evels of linguistic stylistic analysis, i.e., graph ological, phonological, lexical, syntactic, semantic and disc oursal. The present study makes an attempt at the interpretive or analytical research and gives a lin gu stic interpretation and analysis of Keats’ ‘Ode to a Nightingale’ from a single aspect of stylistic stud y i. e. at the lexical level. At the lexical level of the linguistic framework, ‘Ode to a Nightingale’ is ana lysed to find out the noticeable lexical features, the construction of phrases, and ways the poet adopts f r forming new words and expressions.
TWENTY-SECOND INTERNATIONAL CONFERENCE ON COMPOSITE MATERIALS (ICCM22) THERMOGRAPHIC ASSESSMENT OF FIBRE REINFORCED 3D PRINTING FILAMENT

This research demonstrates the feasibility of active thermography for online inspection of 3D printing filaments has and its potential to be used to provide quality assurance of short and natural fibre reinforced composites. 3D printing of materials is widely used across a range of industries. Natural fibre composites materials offer sustainable and cost-effective solutions to material challenges. When considering combining natural fibres and 3D printing there are several manufacturing challenges that must be overcome. The focus of this research is to ascertain if active thermography is a suitable tool for online inspection of fibre reinforced filaments used for 3D printing composites. The aim of the inspection is to identify fibre rich and fibre poor regions along the filament, where uniformly distributed fibres along the filament is preferred. Regions with a locally high weight percent of fibres, known as a fibre bunch, can cause problems when used to print a part resulting in a waste of materials and failed print jobs. The paper presents a feasibility study showing the potential of using pulsed thermography to identify fibre bunching. An external heating stimulus is applied to the filament and an infrared detector is used to monitor the thermal decay. The thermal contrast produced by fibre bunches compared to regions of uniformly distributed fibres is used to identify potential problem areas and provide a means of quality control. Investigation includes variation of the heating stimulus, data collection and data processing routines.
WHAT MOTIVATES TEACHERS TO DEVELOP CRITICALLY INFORMED CITIZENS IN THE MATHEMATICS CLASSROOM?

The study outlines what motivates some secondary mathematics teachers to develop critically informed citizens in the mathematics classroom. Data was collected through eight semi-structured interviews which outlined the teachers’ own experiences and pedagogical approaches relating to developing students as critically informed citizens in the secondary mathematics classroom. An adapted version of Ernest’s model of mathematics-related belief systems was used as card sort prompts for the interview. The same model was also used to analyse the interview data and identify what motivated teachers to take this pedagogical approach. Evidence from the study suggests that teachers from diverse mathematical beliefs and academic backgrounds are motivated to develop students into informed citizens in the mathematics classroom because they have an underlying concern for the student. This underlying concern is not necessarily reflected in the teacher’s mathematical belief system.

Multi-Armed Bandit algorithm for news recommendation systems

Online platforms use recommender systems to learn user preferences and to recommend personalized items that are likely to be interesting to us. One recommender strategy widely employed is called collaborative ﬁltering. This involves grouping users based on similar preferences and then recommending items users have liked to other users in the same group. One drawback of this technique is that the system fails to make recommendations for new items or new users introduced to the system for which it does not have any/suﬃcient information. The issue described is known as the cold-start problem. In order to tackle the cold-start problem, this dissertation investigates the use of Multi-Armed Bandits algorithms for very fast learning which allow us to match the new elements with their respective clusters. To discover the preferences of new users, we show them a series of items that they need to rate. When learning about a new item instead, the goal is to show the item to a sequence of users who can distinguish between the groups in the fastest way possible. How to pick the items to be rated or the users to ask about the new item is a design choice that diﬀerentiates between the diﬀerent strategies used to combat the cold-start problem. The work is carried out on a standard news dataset and the performance is evaluated against the state of the art approaches that use Decision Trees to map the new elements to their corresponding clusters. The results show that the Multi-Armed Bandit algorithms can be used successfully to ﬁnd out which clusters the new users belong to and that they generally outperform the Decision Trees approach. The work has also shown promising results when the setup is reversed and the system needs to deal with new items instead of new users.
Optimum Sizing of Standalone Hybrid PV/Wind Power Generation System in Egypt

In this study, the I-V and P-V curves of PV system at different solar radiations and ambient temperatures have been determined based on five-parameter equations describing the PV module. Also, the wind turbine performance model has been developed and the predicted power-speed curves have been validated against data sheet and experimental data. Both PV module and wind turbine models have been carried out in PSIM software environment. The sizing of hybrid PV/wind/storage battery power generation system has been implemented in HOMER software environment. The sizing results demonstrate that at meteorological conditions of solar radiation, wind speed, and ambient temperature in Borg Elarab area the PV/storage battery system is more feasible than hybrid PV/wind/storage battery system. Consequently, the PV/storage battery system has Net Present Cost (NPC) of $43571 against $45232 for hybrid PV/wind/storage battery system. In addition, by using fuel cell system with PV/storage battery system the excess electricity production is reduced from 1973 kWh/yr (22.4%) to 986 kWh/yr (8.7%) and NPC is reduced from $43571to $29744 which corresponds to about 31.73% reduction in system cost.
ASSESSMENT OF THE INTESTINAL AND VAGINA MICROBIOMA DURING EXTRACORPORAL FERTILIZATION PROGRAMS

It is now known that the possibility of conceiving and carrying a pregnancy is largely due to the interaction of a woman's macroorganism with microorganisms involved in the formation of the microbiome of the intestine, vagina and other organs. Attempts to treat infertility using in vitro fertilization (IVF) are not always successful. Probably, the disruption of the vaginal and intestinal microbiome can significantly reduce the effectiveness of IVF programs. The aim of our work was to study the vaginal and intestinal microbiome in women with infertility in preparation for IVF programs. Materials and research methods. 40 women suffering from infertility were examined. Primary infertility was in 12 women and secondary in 28 patients. Of these, the 1st group consisted of 20 women suffering from infertility who had 2-4 unsuccessful IVF attempts in history; Group 2 consisted of 20 women who, after infertility treatment, had a pregnancy that ended in premature birth. The control group consisted of 20 healthy women. Bacteriological studies of the vaginal and intestinal microbiome were carried out using the method of light microscopy. The level of proinflammatory and anti-inflammatory cytokines in the blood serum was determined by the enzyme immunoassay. Results. When conducting bacteriological examination in the 1st and 2nd groups of patients, it was found that the vaginal microbiome is characterized by a sharp decrease in normal flora (lacto-, bifidobacteria) and a significant increase in opportunistic flora (eubacteria, prevotella, peptostreptococcus). In the intestinal microbiome, a decrease in species diversity, an increase in the number of enterococci, Klebsiella, proteobacteria, characteristic of intestinal dysbiosis associated with inflammation, were found. Thus, in both groups of women, a violation of the vaginal microbiome was found in 71.7%, a violation of the intestinal microbiome in 86.7% of patients. While in the control group, there was no violation of the vaginal microbiome, and the violation of the intestinal microbiome occurred in 10% of women. Conclusions. According to the results of the study, it can be considered that the risk factors for failed IVF attempts and premature birth are a violation of the microbiome of the vagina and intestines, as well as an imbalance of pro-inflammatory and anti-inflammatory cytokines in women with infertility. To develop individual fertility treatment programs, it is necessary to include an assessment of the vaginal and intestinal microbiome in the examination. In addition, drugs that normalize the microbiome of these organs should be included in IVF programs and for the prevention of preterm birth in women with a history of infertility, which will increase the effectiveness of IVF programs and reduce reproductive losses.
Unusual Fragility and Cooperativity in Glass-Forming and Crystalline PVDF/PMMA Blends in the Presence of Multiwall Carbon Nanotubes

Poly(vinylidene fluoride) (PVDF) and poly(methyl methacrylate) (PMMA) are completely miscible below 50 wt % PVDF in the blends. In this work, an attempt was made to understand the fragility/cooperativity relation in glass-forming and crystalline blends of PVDF/PMMA and in the presence of a heteronucleating agent, multiwall carbon nanotubes (CNTs). Hence, three representative blends were chosen: a completely amorphous (10/90 by wt, PVDF/PMMA), on the verge of amorphous miscibility (50/50 by wt, PVDF/PMMA), and crystalline (60/40 by wt, PVDF/PMMA) blends. The intermolecular cooperativity/coupling, fragility, and configurational entropy near the glass transition temperature (T-g) were studied using differential scanning calorimetry (DSC) and broadband dielectric relaxation spectroscopy (DRS). It was observed that the blends with higher concentration of PMMA were more fragile (fragility index m = 141) and those with higher concentration of PVDF were more strong (m = 78). Interestingly, the coupling was less in the glass-forming blends (10/90 by wt, PVDF/PMMA) than the crystalline blends as manifested from DRS. This observation was also supported by DSC measurements which reflected that the cooperative rearranging region (CRR) existed over a smaller length scales in fragile blends as compared to strong blends, possibly due to restricted amorphous mobility. This effect was more prominent in the presence of CNTs, in particular for 50/50 (by wt) and 60/40 (by wt) PVDF/PMMA blends. Further, the configurational entropy, as manifested from DRS, decreased significantly in the strong blends in striking contrast to the fragile blends, supported by DSC, which manifested in an increase in the volume of cooperativity in the strong blends. The higher coupling in the crystalline blends can be attributed to good packing of the amorphous regions. While this is understood for crystalline blends (60/40 by wt, PVDF/PMMA), it is envisaged that enhanced dynamic heterogeneity is accountable for increased coupling in the case of blends which are on the verge of amorphous miscibility (50/50 by wt, PVDF/PMMA). The latter is also supported by broad relaxations near the T-g in DRS. Interestingly, the intermolecular coupling in the blends in the presence of CNTs has reduced, though the potential energy barrier hindering the rearrangement of CRR is lower than the blends without CNTs. In addition, the amorphous packing is not as effective as the blends without CNTs. This is manifested from reduced volume of cooperativity in particular, for 50/50 (by wt) and 60/40 (by wt) blends.
Natural cellulosic material characteristics: A possibility to develop antimicrobial active fiber-based packaging

Coconut husk, rubberwood sawdust, and palm leaf base are cellulosic agricultural wastes that have potential to be processed to fiber as absorbing material. This study investigated characteristics (morphological, physiological properties, chemical composition, absorption capacity, and water absorption isotherms) of coconut, rubberwood, and palm fiber. Also, the study aimed to develop an antimicrobial sachet packaging to resist against foodborne pathogens (Listeria monocytogenes, Staphylococcus aureus, Salmonella spp., and Escherichia coli) by adding lime oil (LO) emulsion or Litsea cubeba (LC) oil at 50 to 700 μL into the material (1 g) before, and then dried and placed in the 1-L seal box. Results showed that among the three, coconut performed the best in terms of releasing the essential oil (EO) emulsion against bacteria. Coconut could adsorb and release volatile LO or LC at the lowest concentrations (LO, 500 μL/L; LC, 300 μL/L) to inhibit bacteria compared with the other fibers (700 μL/L) at 35 °C. Results indicated that coconut has a low water absorption rate, which influenced the faster adsorption of EO emulsion in the beginning of the process; therefore, using low concentrations of EO in coconut for bacterial inhibition is possible. Coconut contains 34.5% lignin, 68.7% holocellulose, 37.6% cellulose, and 31.2% hemicellulose. Coconut is suitable as an alternative to the biocomposite material in developing a new antimicrobial packaging design.
Video Retrieval by Managing Uncertainty in Concept Detection using Dempster–Shafer Theory

—This paper focuses on concept-based video retrieval which examines whether a shot is relevant or irrelevant to a query based on detection results of concepts, like Person , Building and Car . One key problem is uncertainty in concept detection. Even for state-of-the-art methods, it is difﬁcult to accurately detect concepts present in a shot. Relying on such uncertain concept detection results degrades retrieval performance. To overcome this problem, Dempster–Shafer Theory (DST) is used to represent the probability that a concept is possibly present in a shot. By incorporating DST into maximum likelihood estimation, our method estimates the probabilistic distribution of concepts’ presences which characterize shots relevant to the query. A preliminary experiment on TRECVID 2009 video data supports the effectiveness of our method.
Gender Dysphoria Treatment: A Critical Discussion of Medical and Psychotherapeutic Approaches in Adults and Young People

Gender Dysphoria focuses on the psychological state at which individuals experience low levels of perceived satisfaction regarding their primary and secondary physiological traits, their biological gender, and their assigned societal gender roles. This condition primarily requires multidisciplinary and personalised treatment. Scientific evidence suggests that utilisation of gonadotropin-releasing hormone analogues, puberty blockers, and genderaffirming surgery may reduce distress, enhance mental health and quality of life, while diminishing Gender Dysphoria. However, some researchers contend that medical procedures pose adverse limitations since they may result in complications, feelings of frustration, and supplementary procedures undergone for aesthetic purposes. Moreover, individuals’ age of readiness to pursue medical interventions and deal with additional issues such as post-surgery fertility and regret also need to be addressed. Conversely, psychotherapy and counselling intend to assist such individuals in accomplishing long-term relief relating to their gender identity, developing their interpersonal skills, and confronting Gender Dysphoria comorbidity. Yet, many psychotherapeutic schemes insufficiently address crucial facets of Gender Dysphoria, namely societal discrimination stemming from subsequent stigmatization, promotion of resilience among this highly marginalised population against unprecedented tribulation, and body dissatisfaction, thus not providing a complete relief of gender dysphoric feelings. Therefore, it is essential to appropriately address psychosocial functionality enhancement, integrate novel treatment propositions into a holistic therapeutic plan, and further develop/validate Gender Dysphoria metrics that can be universally accepted in order to prevent pathologisation of these individuals. It is also recommended that further qualitative data, needs assessments, and empirical studies be gathered, while carefully abiding by the necessary ethical considerations.
Potency of jellyfish alkaloid (Aeginura sp) on kidney histopathology and relative percent survival (RPS) of tiger grouper (Epinephelus fuscoguttatus) against Vibrio harveyi

The purpose of this research were to determine the effect of alkaloid jellyfish compounds on kidney histopathology and to know the best doses to the Relative Percent Survival (RPS) of tiger grouper. The method of this research was descriptive and treatment with Completely randomized design. The treatment of active alkaloid compound on feed was given for 28 days. And then challenge-tested to 107 cells.ml−1 of Vibrio harveyi into the media for one day. Using alkaloids compound of Aeginura sp. on the feed with the doses of Control= 0 g alkaloid / kg feed; A = 0.5 g alkaloid / kg feed; B = 0.75 g alkaloid / kg feed; C = 1.0 g alkaloid / kg feed; Alkaloid D = 1.25 g / kg feed. The result of the scoring shows that the 4 treatment with given alkaloid dosage are able to decrease the damage level on the tissues of the fish’ kidneys. The average total damage of treatment C =1gr Alkaloid dosage is found to have the lowest value compared to another treatment with the percentage damages of 13,47% which is categorized low. Those results show better value than the infected fish without any medication with total damage of 42.27% within the medium category. The best RPS was found at a treatment of C with the value of 100%. For further study, it was suggested using a dose of 1 g alkaloid / kg feed for the best result. It was proved by an absent of the damage on kidney and the value of RPS reached 100%.
A Review of the Material Characteristics, Antifreeze Mechanisms, and Applications of Cryoprotectants (CPAs)

Cryopreservation has been a key technology in medical science, food preservation, and many other fields. In a freezing process, the formation of ice crystals may cause significant damage to the frozen samples. In order to reduce the damage, many cryoprotectants (CPAs) have been developed and added in cryopreservation processes for reduced ice volume, decreased ice size, proper ice shaping, and cell protection. According to the material characteristics, the CPAs are either impermeable (i.e., antifreeze protein, polyampholytes, and polyvinyl alcohol) or permeable (i.e., dimethyl sulfoxide, proline, and glycerol) to cell membranes. The typical CPAs are introduced in this work with their material characteristics, antifreeze mechanisms, and applications. Antifreeze mechanisms for different CPAs involve molecular adsorption on the ice surface, hydrogen bonding to ice, bending the ice surface, lowering the freezing point, inhibiting ice recrystallization, protecting cell membranes, reducing dehydration of cells, and breaking hydrogen bonds among ice crystals to reduce the size of ice crystals. In practice, different CPAs can be used together with their cryopreservation properties functioning synergetically. This study reviews the recent applications of CPAs in food, biology and medicine, and agriculture. Future works for CPAs are suggested in improving efficiency, revealing mechanisms, broadening application, and finding new CPAs.
