Short-Term Forecasting of Off-Street Parking Occupancy

Information and communication technologies have opened the way to guide recent developments in the field of parking. In this paper these technologies are applied to model a decision support system that gives insight into 6-months ahead parking occupancy forecasts for 57 off-street parking locations in Amsterdam. An effect analysis was conducted into the influence of weather-, event-, parking tariff-, and public transport attributes on parking occupancy. The most influential factors on the parking occupancy were the scheduling of artistic and sports events, the addition of a public transport line, and the weather variables thunderstorm, average wind speed, temperature, precipitation, and sunshine duration. Parking tariffs did not significantly contribute to model performance, which could have been because of the lack of data and time variability in the parking tariffs of the examined parking locations. The forecasting algorithms compared were the seasonal naive model as a benchmark approach, the Box–Jenkins seasonal autoregressive integrated moving average with and without exogenous regressors (SARIMAX and SARIMA, respectively), exponential smoothing models, and the long short-term memory neural network. The SARIMAX model outperformed the other algorithms for the 6-months ahead forecasts according to the lowest root mean square error (RMSE). By including the event factor, the model improved by 24% based on the RMSE. Weather variables improved the predictive performance by 8%. Future studies could focus on the addition of more event variables, extension into an online model, and the impact of spatial–temporal features on parking occupancy.
Aging models and adaptive SOC estimation for lithium ion batteries

The thesis mainly consists of two significant parts namely, State of Charge estimation and the State of Health estimation. Firstly, the SOC estimation makes use of two critical methods which are Recursive Least Square method (RLS) and Extended Kalman Filter (EKF) to estimate the battery parameters and to update the battery state equations respectively. The model is tested for synthetic test cases and driving cycles like NEDC. The results obtained from real drive cycle cases are compared with the reference data provided by the supervisors. The primary advantage of this estimation algorithm is that it allows for better accuracy than existing methods like Coulomb counting and Open Circuit Voltage (OCV) estimation methods. The second part of this thesis majorly focuses on deriving life cycle models for Lithium-ion cells. The cells under consideration are Lithium iron (LFE) and NMC cells for which three models are built namely, Model A, Model B and Model C. The Models A & B focus on the Lithium iron cells while Model C on NMC cells. The main parameters under discussion are temperature, C-rate, SOC window (DOD) and capacity throughput. All these factors are deemed as stresses acting on the cell which affects the life of the battery. To start with a single stress model is built and further, based on the reflections from Model A, a multi-stress models B and C are developed.
Development of Unstructured Mesh-Based Numerical Method for Sodium-Water Reaction Phenomenon

Abstract When pressurized water or vapor leaks from a failed heat transfer tube in a steam generator (SG) of sodium-cooled fast reactors, a high-velocity, high-temperature jet with sodium-water chemical reaction may cause wastage on the adjacent tubes. For safety assessment of the SG, a computational fluid dynamics code SERAPHIM, in which a compressible multicomponent multiphase flow with sodium-water chemical reaction is computed, has been developed. The original SERAPHIM code is based on the finite difference method. In this study, an unstructured mesh-based numerical method was developed and introduced into the SERAPHIM code to advance a numerical accuracy for a complex-shaped domain including multiple heat transfer tubes. The multiphase flow under the tube failure accident is calculated by the multifluid model considering compressibility. The governing equations are solved by the Highly Simplified Marker And Cell (HSMAC) method. The original HSMAC method was modified for compressible multiphase flows in the unstructured mesh. Validity of the unstructured mesh-based SERAPHIM code was investigated through the analysis of an underexpanded jet experiment, which is a key phenomenon in the tube failure accident. The calculated pressure profile showed good agreement with the experimental data. Numerical analysis of water vapor discharging into liquid sodium was also performed. The calculated behavior of the reacting jet agreed with the previous experimental knowledge. It was demonstrated that the proposed numerical method could be applicable to evaluation of the sodium-water reaction phenomenon.
Pure Spin Current and Negative Differential Resistance in Born Nitride Nanoribbon Induced by Oxygen Doping

Boron nitrogen nanoribbon (BNNR) is semiconductor, doping is an important way to change the size of its bandgap. In this paper, oxygen doping armchair and zigzag BNNR (aBNNR and zBNNR) were studied by density functional and non - equilibrium Green 's function method. The substitution of nitrogen atoms by the oxygen atom in the BNNR introduces impurity state between the bandgap of the BNNRs. The impurity state is spin-splitting completely, and the system behaves ferromagnetic with 1μB per supercell. The dispersive of impurity band introduced by Oxygen doping is very small, so it shows a strong localization. Considering the transport properties of oxygen-doped boron-nitrogen nanotubes, armchair type and zigzag type are different. For the aBNNR, pure spin current appears in the symmetrical range of positive and negative voltage, the peak of current is 32 μA, and the negative differential resistance is shown simultaneously. For the zBNNR, the positive and negative voltage interval is no longer symmetrical, the peak current is only 2.0 μA. BNNR doped by oxygen have unique electronic structures and transport properties, so which provide more option for optoelectronic and spintronic devices.
Prevalence of domestic violence and abuse among Saudi women: an online based cross-sectional study

Background: Domestic violence and abuse (DVA) has a major impact on women's lives, their psychological, physical, and reproductive health and mostly occurring behind closed doors. The objective of this study was to explore the prevalence of DVA among Saudi women, to determine factors related to each type of abuse, identify sources of abuse, and level of disclosure.Methods: A cross-sectional study was conducted through an online survey using social networking platforms. Four hundred and twenty-one women completed the validated Arabic version of the NorVold domestic abuse questionnaire.Results: The lifetime prevalence of DVA was 69.9%. The most prevalent type of violence was emotional abuse, followed by physical abuse (47%), and subsequently sexual abuse (35%). Among the abused women, 25.6% (n=75) had experienced all types of abuse. Fathers, mothers, and brothers were the main perpetrators of emotional violence, while brothers, mothers, and fathers were the main perpetrators of physical abuse; relatives (not from the family) and brothers were the main perpetrators of sexual violence. Approximately 26% of the emotionally abused try to seek help, 78.7% did not disclose the abuse to their doctors, and 16.5% of the physically abused try to seek help; however, 82.2% were unable to inform their doctors after abuse, only 8.7% of sexually abused women try to get help after abuse, and 90% cannot inform their doctors.Conclusions: DVA against Saudi women is unacknowledged, and national research data are urgently required to assess the prevalence of DVA and risk factors for abused women.
How Audience Diversity Affects Consumers’ Creation of Brand Posts on Facebook: A Cross Cultural Examination

ABSTRACT The purpose of this study is to investigate cultural influence on the creation of brand-related posts on Facebook, with a particular focus on the mediating roles of the diversity of user audiences, as well as the intensity of Facebook use. The online survey was conducted with a representative sample of respondents from South Korea, Thailand, the Netherlands, and the United States (N = 802). The findings show that cultural differences at both personal and national levels play a role for social relationships between users and their audiences with consequences for the creation of brand posts. Specifically, as a result of audience diversity, users in individualistic cultures create brand-related content more frequently than users in collectivistic cultures, partly as a consequence of their higher Facebook use.
Becoming a wage earned or a self-employed: Does Young Educational Level determine the Choice of the Working Labour Force Status in Cameroon?

If employment is recognized as a key driver for growth, development and well-being improvement, human capital is probably a main determinant of the labour force participation. By often analyzing this relationship in wage earning jobs, studies used to leave self-employment untreated despite the fact that its proportion is growing significantly in several countries. This leads us to the following question: does human capital accumulated determine access to all forms of employment? Focusing on young people, this article analyzes effects of educational level used as a proxy of the human capital accumulated on the choice of the working labour force status in Cameroon. Using discrete-choice models on data draw from the second Employment and Informal Sector Survey carried out by the National Institute of Statistics, empirical findings reveal that educated young people are more disposed to make a decision to work as wage earned and the corresponding probability rises with the increasing of their educational levels. However, their willingness to become self-employed decline with the rising of their educational levels. Therefore, compared to the decision to work as a wage earned, becoming a self-employed does not appear as a human capital outcome. This paradoxical result for a low wage economy suggests a reform of the educational or training system starting at least in high school level with emphasizes in sectors with a high potential of self-employment and a setting-up of an apprenticeship plan.
Engaging with critical literacy through restorying: a university reading and writing workshop on fairy-tale reimaginations

ABSTRACT This article presents the findings of a university reading and writing workshop on fairy-tale reimaginations. Fairy-tale reimaginations, understood as rewriting fairy tales using alternative narrative techniques, can be introduced into a literacy classroom where learners read reimagined fairy tales that stimulate their critical response and subsequently reimagine new stories that interrogate presumptions in the traditional tales. To justify the design of the workshop and its effectiveness in enhancing student learning, I combine restorying and critical literacy as the theoretical framework. By theorising fairy-tale reimaginations as a form of restorying, I foreground fairy-tale reimaginations as acts of resistance that reflect more diversifying perspectives in the society (Thomas & Stornaiuolo, 2016). I have chosen the four dimensions of critical literacy (FDCL), synthesised by Lewison et al. (2002) to illustrate how the workings of fairy-tale reimaginations befit the general principles of critical literacy. For a fuller realisation of critical literacy through consumption, production, and distribution of texts, understood as action and reflection upon the action, I contend to develop a reading/writing pedagogy that places emphasis on reading and rewriting followed by sharing and reflection. To this end, I hope to offer teacher-researchers insights to bring the fantasy genre into their literacy classroom.
Nutritional Composition and Sensory Evaluation of Cake Fortified with Moringa oleifera Leaf Powder and Ripe Banana Flour

Micronutrient deficiency is raising concern worldwide, especially among children and pregnant women in Africa, Southern Asia, and certain developing countries, posing a significant risk to the nutritional status. This study aimed to develop cake fortified with Moringa leaf powder (MOLP), ripe banana flour (RBF) and assessed the effect of MOLP and RBF on the nutritional composition as well as consumer acceptability. The nutritional, mineral, vitamin A and sensory attributes of MOLP and RBF fortified cakes were assessed. Proximate analysis results showed that the addition of MOLP and RBF significantly increased from 5.79% to 8.90% for protein, 1.25% to 1.66% for ash, 2.70% to 6.98% for fiber, and 53.0% to 60.88% for carbohydrate. However, the fat and moisture content decreased from 20.16% to 13.06% and 17.77% to 13.54%, respectively. The mineral contents (phosphorus, potassium, iron, and zinc) increased significantly in the fortified cake compared to the unfortified control. The vitamin A content (3.40–5.62 mg/100 g) of the fortified cakes was significantly (p < 0.05) higher than the vitamin A (1.62 mg/100 g) content of the unfortified cake. Although MOLP and RBF substitution raised most of the nutritional contents, the maximum consumer acceptability was recorded in the unfortified control, which was statistically similar to C2 (1.5% MOLP and 2% RBF) substitution in terms of shape, sweetness, flavor, mouth feel, and overall acceptability. The results indicated that cake supplemented with 1.5% MOLP and 2% RBF provided the enriched nutritional quality and potentially contributed to the improvement of food and nutritional security of the vulnerable populations. Furthermore, utilizing ripe bananas with peels in cake recipes will help to encourage the recovery of food waste for functional food preparation.
Effect of fish meal substitution with lima bean meal on growth and feed utilization in common carp fry, Cyprinus carpio

An experiment was conducted in an earthen pond in the west region of Cameroon to investigate the level of replacing fish meal (FM) with lima bean meal (LBM) on zootechnic parameters in common carp fry. Four hundred and fifty fish weighing 0.91±0.03 g were divided into five groups of 90 fish each. In control group (LBM-0), fish received normal feed, while in four experimental groups, FM was replaced with LBM at 10%, 20%, 30% and 40% corresponding to LBM-10, LBM-20, LBM-30 and LBM-40. Fish were fed three times daily for 84 days. Every 14 days, fish were harvested for weight determination. The results obtained showed significant increases in weight gain (WG) and specific growth rate (SGR). After 84 days of feeding, fish fed in LBM-40 showed a WG of 6.47 ± 0.48 g and SGR of 2.70 ± 0.11%/d compared to LBM-0 (WG=3.52 ± 0.17 g and SGR=1.95 ± 0.08%/d), corresponding to a significant increases of 58.27% and 27.77% respectively. Concerning feed utilisation, LBM-10 produced the greatest effect with the lowest feed conversion ratio (FCR=0.71±0.05) and the highest protein efficiency ratio (PER=3.54±0.26) compared to LBM-0 (FCR=1.09±0.12 and PER=2.36 ± 0.25). These results showed that FM substitution with LBM improves growth and feed utilization in Cyprinus carpio fry. Keywords : Cyprinus carpio , fish meal, lima bean, growth, feed utilization.
Accuracy of Different Head Movements of Intraoral Scanner in Full Arch of Both Maxilla and Mandible

This in vitro study aimed to compare the accuracy of maxilla and mandible full-arch scans from an intraoral scanner via one scan path with six different head movements. Standard maxilla and mandible models via holder were set in a dental chair to simulate position and posture. The reference models’ standard tessellation language (STL) files were formatted via desktop scanner, and operative models’ files were obtained via IOS TRIOS 3 Pod as superimposed by Exocad CAD software. The same scan path with six head movements (Linear, Circle, Wave, 8-figure, S-figure, and A-P) were designed to scan 10 times per jaw, and a total of 120 scan files were then compared with reference files. The data were recorded and deviations of both occlusal and B-L sides were compared, with statistical analysis being performed by one-way analysis of variance (ANOVA) and post hoc comparisons with Tukey test. The trueness of optical impression for full-arch via one path with six head movements differed from maxilla and mandible and depended on the different movements (p < 0.05). In the same path, peak deviation was found at the turning points for left central incisor, left first premolar, left second molar, and right second molar in maxilla, and for right first premolar, second molar, and left second molar in the mandible. The 8-figure movement showed the highest deviation (0.128 ± 0.086 mm) in the maxilla and (0.105 ± 0.069 mm) in the mandible. The Linear movement presented the lowest deviation (0.096 ± 0.07 mm) in the maxilla while the Circle movement presented the lowest deviation (0.073 ± 0.041 mm) in the mandible, with the 8-figure movement showing the worst precision among six movements. In the maxilla, the S- and 8-figure movements were not recommended, while the Linear and Circle movements showed high trueness. In the mandible, the 8-figure movement was not recommended, while the other five presented similar lower deviations.
Is Capillary Refill Time an Early Prognostic Factor in COVID-19 Patients

Amaç: Hipoksemi, koronavirüs hastalığında (COVID-19) prognozu belirlemek için kullanılan hayati bir kriterdir. Bu çalışmada, COVID-19 hastalarında hipoksiye bağlı hastalık şiddetini tanımlamada kapiller dolum zamanının (KDZ) etkinliği değerlendirilmiştir. Hastalar ve Yöntem: Bu prospektif çalışma, COVID-19 hastaları ve yaşça eşleştirilmiş bir sağlıklı grubu ile gerçekleştirilmiştir. Ölçüm için optimum test ortamı sağlandı ve yöntemimizi standartlaştırmak ve ölçümleri (milisaniye cinsinden) kaydetmek için sabit bir akıllı telefon platformu kullanıldı. Kaydedilen videolar daha sonra bir video işleme programı kullanılarak değerlendirildi. Bulgular: Çalışmaya toplamda 39 COVID-19 hastası ve 40 kontrol grubu katıldı. Hastalar hastalık şiddetlerine göre orta (n= 25) veya ağır (n= 14) gruplara ayrıldı. Her iki orta / şiddetli grubun ortalama oksijen satürasyonu %94'ün üzerindeydi. Hastalık şiddetine göre KDZ ölçümleri şiddetli grupta orta gruba göre daha yüksekti (p= 0.009). Lenfopeni olmayan hastalarda (n= 18), KDZ değerlerinin şiddetli grupta arttığı saptandı (p= 0.008). Covid-19’lu hastaların takibinde KDZ kullanımı uygulanabilirdi (AUC: 0.91; %95 SH 0.848-0.978; P= 0.001) Sonuç: Sonuçlarımız, COVID-19’lu hastalarda KDZ süresinin uzayabileceğini göstermektedir. Lenfopenisi olmayan ve O2 seviyesi normal olan hastalarda, KDZ uzamasının saptanması yoğun bakıma erken kabul için bir kriter olabilir.
Five-year follow-up of endoscopic resection of symptomatic os trigonum: a prospective interventional cohort study of a possible cause of ankle and big toe pain

Background: The authors aimed to evaluate the functional outcomes of endoscopic resection and debridement of symptomatic os trigonum and associated inflammatory changes including the flexor hallucis longus (FHL) pathologies. Methods: A prospective interventional study was conducted including 28 patients with 32 symptomatic os trigonum in the period from January 2010 to March 2016. The mean age of patients was 23.6 yr (range, 12 to 45 yr). All patients completed a minimum follow-up of 5 yr. Outcomes were assessed by the 100-mm visual analogue scale (VAS), American Orthopedic Foot and Ankle Society score (AOFAS), and the postoperative complication rate. Results: Endoscopic examination revealed tibiotalar and subtalar hypertrophic synovitis in 14/32 and 13/32 patients, respectively. A small bony prominence encroached upon the FHL in 3/32 patients, 18/32 patients had FHL tenosynovitis, and the FHL tendon was constricted at its entry point into the tarsal tunnel requiring release of the flexor retinaculum in one patient. The mean AOFAS and the VAS scores significantly improved at final follow-up. The degree of improvement of AOFAS and the VAS scores was greater for the posterior ankle impingement group than the os trigonum fracture group. All patients experienced no major complications. Conclusions: Posterior endoscopic excision of a symptomatic os trigonum is safe, feasible, and has excellent results in patients with various sporting or occupational activities. The degree of improvement is greater for patients without os trigonum fracture. Level of Evidence: Level IV.
Coexistence of Superconductivity and Topological States in 2M WS2 Compound with a Recorded Tc among TMDs

Recently intriguing physics of superconductivity, type-II Weyl semimetal or quantum spin Hall states was discovered in metastable 1T'-type VIB-group transition metal dichalcogenides (TMDs). Even the topological superconductivity can be induced if the superconductivity and nontrivial topology coexist in this type of materials. Here, we report 2M WS2 new compound constructed from 1T' WS2 monolayers, whose superconducting transition temperature Tc of 8.8 K is the highest among all the intrinsic TMDs. The coexistence of the electron and hole pockets was observed from first-principles calculations and Shubnikov-de Haas (SdH) oscillation. Moreovoer, the topological surface states with a single Dirac cone appear on the (100) surface. Our finding reveal a strong evidence of the topological superconductivity in the 1T' MX2 system.
Breaking Stereotypes About Alumni Donors: Who Gives First? A Discrete-Time Hazard Model

ABSTRACT Institutions of higher education are relying on philanthropy and fundraising at a greater level than ever before seen. This increased focus has led scholars to investigate various predictors regarding which alumni are likely to give and which are likely to give the most. To date, however, scholars have not yet examined the role of timing and when alumni give their first gift to their alma mater. Using discrete-time hazard modeling (DTHM), this paper seeks to re-center the current conversation surrounding educational philanthropy by exploring not simply who gives the most, but rather who gives and when. Using data of alumni from a predominantly White, private-research university in the United States (n = 3,404), we find that those alumni who were in cultural clubs, as well as Black and multi-racial alumni, are more likely to give their first gift at an earlier date than other alumni. Additionally, alumni that participated in fewer student activities while at school appear more likely to give their first gift sooner, while gender, income, and alumni activity participation show no significance in the model. This study upends some commonly held stereotypes of who are donors to higher education. We share implications for practice and future research.
