LONG-TERM VISUAL LOCALIZATION IN LARGE SCALE URBAN ENVIRONMENTS EXPLOITING STREET LEVEL IMAGERY

Abstract. In this paper, we present our approach for robust long-term visual localization in large scale urban environments exploiting street level imagery. Our approach consists of a 2D-image based localization using image retrieval (NetVLAD) to select reference images. This is followed by a 3D-structure based localization with a robust image matcher (DenseSfM) for accurate pose estimation. This visual localization approach is evaluated by means of the ‘Sun’ subset of the RobotCar seasons dataset, which is part of the Visual Localization benchmark. As the results on the RobotCar benchmark dataset are nearly on par with the top ranked approaches, we focused our investigations on reproducibility and performance with own data. For this purpose, we created a dataset with street-level imagery. In order to have independent reference and query images, we used a road-based and a tram-based mapping campaign with a time difference of four years. The approximately 90% successfully oriented images of both datasets are a good indicator for the robustness of our approach. With about 50% success rate, every second image could be localized with a position accuracy better than 0.25 m and a rotation accuracy better than 2°.
Biological Activity of Matricaria chamomilla Essential Oils of Various Chemotypes

Abstract The essential oil of Matricaria chamomilla L. , which is commonly used for medicinal and cosmetic purposes, can be differentiated between several chemotypes. In the current study, six essential chamomile oil samples of various origins (four of commercial sources, one of cultivation, one of wild collection) were examined regarding their composition and biological activities, i. e. , antibacterial, antifungal, mosquito repellent, and larvicidal effects. GC-MS analyses revealed that the samples largely varied in composition and could be attributed to various chemotypes. In contrast to the other two samples, the four commercial samples were unusually high in trans-β-farnesene. The overall antimicrobial effects were only moderate, but it could be shown that a higher content in α-bisabolol and a smaller in α-bisabolol oxides A and B had a positive effect on overall activity. All samples had a biting deterrent effect comparable to DEET. Higher concentrations of (Z )- and (E )-spiroethers improved larvicidal activity, whereas trans-β-farnesene had the opposite effect. In conclusion, the importance of α-bisabolol for the biological activity of chamomile essential oil could be demonstrated.
Associations between Pathological Internet Use and Depression, Anxiety, and Suicidality among College Students

In recent years, Internet has been used worldwide and has become an essential tool, especially for younger age groups. It is important to explore Internet-use habits and any influence they can have on users. Although a term accurately describing the clinical features of Internetrelated behavioral problems is not yet available, it can be generally defined as: “Use of Internet that cannot be controlled and that produces psychological, social, academic, and/or work problems”, and it has been described by various terms such as Internet addiction, compulsive Internet use, problematic Internet use, and pathological Internet use (PIU) [1,2]. Despite the inconsistent use of the term in the literature, the fact that PIU produces negative consequences on users is well-documented. PIU is most relevant to adolescents and young adults. According to 2014 statistics on Internet addiction in South Korea, the highest risk group were adolescents (12.5%), while adults were second (5.8%) [3]. Park et al. [4] reported that adolescents in South Korea who met the criteria for PIU were at significantly increased risk for depression and suicidal ideation. For adults, PIU can result in worse consequences than in adolescents. Recent studies in the United States and Hong Kong have explored the relationships between PIU and family Associations between Pathological Internet Use and Depression, Anxiety, and Suicidality among College Students Ahyoung Yoon, BSc, Young-Eun Jung, MD, PhD, Moon-Doo Kim, MD, PhD
Effect of Intercropping Dates of Lablab (Lablab purpureus L.) with Maize (Zea mays L.) on Forage and Maize Grain Yields

This study was conducted to evaluate effect of intercropping dates of lablab (Lablab purpureus L.) with maize (Zea mays L.) on forage and maize grain yields. It was carried out at Gereb Giba in Tanqua Abergelle district, Tigray, Ethiopia. Randomized Complete Block Design (RCBD) with four treatments and four replications were used. The treatments were sole maize sown (T1) and lablab sown at 10, 20 and 30 days after emergence of maize for T2, T3 and T4 respectively. Intercropping did not affect height and days for 50% flowering of lablab. Similarly, it was not affected height and days for physiological maturity of maize. Lablab forage yield was significantly greater (p<0.01) in T2 and T3 than T4. Maize Stover dry matter (DM) yield was similar among treatments while total forage DM yield was significantly higher (p<0.0001) in T2, T3 and T4 than T1. Moreover, among the intercrops, total forage yield was significantly highest (p<0.0001) for T2 compared to T4 but similar in T2 and T3. Maize grain yield was significantly superior (P<0.0001) in T2 and T3 compared to T1 and T4. Though, T2 and T3 had similarity in all parameters measured, T2 provided Original Research Article Redae and Tekle; AJARR, 13(2): 1-4, 2020; Article no.AJARR. 58954 2 higher forage and maize grain yields than T1 and T4. Therefore, lablab intercropping at 10 days after emergence of maize is appropriate in Tanqua Abergelle district and other areas with similar agro ecologies.
Predictors of Young People’s Career Intentions as Islamic Bankers

Understanding the willingness of university students pursuing their career as Islamic bankers has proven to be one of the most challenging research topics in the Islamic banking field. This study examines the factors affecting the career intentions as Islamic bankers among university students in Malaysia. Drawing upon Decomposed Theory of Planned Behavior (DTPB), this study examined the factors determining the students' willingness to become Islamic bankers as their future job. Our analysis is based on the 350 respondents involved. Results obtained show that all factors are examined were instrumental in determining the career intentions as Islamic bankers. Our findings should be interpreted with caution. We identified two limitations, first is on the use of the university students as proxies and second our data which was confined to Islamic finance program whilst neglecting other students from business and finance disciplines. The results help improve the role of bank managers to provide proper packages of training to improve the students’ confident to become future Islamic bankers. Besides, this study extends the DTPB’s applicability to include career intentions as Islamic bankers in a Malaysia context.
Sequential Foley Catheter and Misoprostol Versus Misoprostol Alone for Induction of Labor in Postdated Pregnancy: a Randomized Controlled Trial

Introduction: Induction of labor is done with the aim of normal vaginal delivery. There are different methods; mechanical like intra-cervical Foley’s or pharmacological agents like misoprostol or dinoprostone. Objectives: To compare sequential use of Foley’s catheter and vaginal misoprostol in comparison with vaginal misoprostol only. Methods: Patients with period of gestation more than or equal to 41 weeks without any complications were assigned randomly according to computer generated randomization into sequential use of intracervical Foley followed by vaginal misoprostol after 24 hours (sequential group) or vaginal misoprostol only. Primary outcome was rate of normal vaginal delivery. Secondary outcomes were induction to delivery interval, maternal and fetal morbidity. Results: Rate of normal vaginal delivery in sequential group (n= 353) and misoprostol alone group (n= 356) was 71.6% and 53.3% (p < 0.001) but the time to delivery from induction is statistically more in sequential group (30.3 vs. 11.2 hours, p< 0.001). Maternal outcomes like postpartum hemorrhage, hyper-stimulation syndrome, chorioamnitis and neonatal outcomes like low Apgar score, meconium stained baby and stillbirth are similar in both the groups. Conclusions: The priming of cervix using intracervical Foley catheter before giving vaginal misoprostol was beneficial in increasing the rate of normal vaginal delivery but it increased the induction to delivery interval.
Macrophage ablation significantly reduces uptake of imaging probe into organs of the reticuloendothelial system

Background Macrophages engulf particulate contrast media, which is pivotal for biomedical imaging. Purpose To introduce a macrophage ablation animal model by showing its power to manipulate the kinetics of imaging probes. Material and Methods The kinetics of a particulate computed tomography (CT) contrast media was compared in macrophage ablative mice and normal mice. Liposomes (size 220 µg), loaded with clodronate, were injected into the peritoneum of three C57BL/6 mice. On the third day, 200 µL of the particulate agent ExiTron nano 6000 were injected into three macrophage-ablative mice and three control mice. CT scans were acquired before and 3 min, 1 h, 6 h, and 24 h after the ExiTron application. The animals were sacrificed, and their spleens and livers removed. Relative CT values (CTV) were measured and analyzed. Results Liver and spleen enhancement of treated mice and controls were increasing over time. The median peak values were different with 225 CTV for treated mice and 582 CTV for controls in the liver (P = 0.032) and 431 CTV for treated and 974 CTV in controls in the spleen (P = 0.016). Conclusion Macrophage ablation leads to a decrease of enhancement in organs containing high numbers of macrophages, but only marginal changes in macrophage-poor organs. Macrophage ablation can influence the phagocytic activity and thus opens new potentials to investigate and manipulate the uptake of imaging probes.
Phase‐current waveform for switched reluctance motors to eliminate input‐current ripple and torque ripple in low‐power propulsion below magnetic saturation

: In recent decades, switched reluctance motors (SRMs) have been attracting increasing attention as a promising type of traction motors for electric vehicle propulsion, owing to their robust construction, elimination of permanent magnets. However, their phase inductance profile contains significant high-order harmonics, which generates input-current and torque ripples under SRM drive with the conventional square phase-current waveform. This study solves this problem by proposing a novel phase- current waveform in replacement of this square waveform. The proposed waveform is a predetermined waveform that can be stored as a look-up table in the inverter controller and can be magnified or attenuated to adjust the output torque, similarly as the conventional square waveform. Certainly, SRMs generally exhibit magnetic non-linearity due to magnetic saturation, which complicates the analysis. Therefore, the proposed waveform is analytically derived under the assumption that the magnetisation of the motor remains below the saturation level because vehicle propulsion tends to require a torque output far smaller than the maximum rating of the motor in normal vehicle travel. The proposed phase-current waveform is experimentally tested in comparison with the conventional square phase-current waveform. Consequently, the proposed waveform revealed smaller ripples in both the input-current and torque, supporting the effectiveness of the proposed phase-current waveform.
The Relationship between Audit Committee Effectiveness and Audit Fees: Insights from Indonesia

This study examines the relationship between the effectiveness of an audit committee and the amount of audit fees. The sample consists of 130 manufacturing companies listed on the Indonesia Stock Exchange (IDX) in 2016–2017. Data are obtained from the IDX and company’s annual reports. The effectiveness of an audit committee is measured by independent audit committee size, frequency of audit committee meetings, and expertise of the audit committee. Results show first that the size of the independent audit committee has a positive effect on audit fees. This finding suggests that an increase in the number of independent audit committee members produces a higher quality of reporting, and so they tend to choose a reputable public accountant. Second, the frequency of its meetings has positive effects on audit fees. It suggests that the more effective the supervision of the committee to improve audit quality, the higher the audit fees to be paid. However, this study fails to provide evidence that the expertise of the audit committee affects audit fees. The result of this study suggests that the audit committee tends to adopt the demand approach based on the reputation of the public accounting firm accountant firm in determining the amount of audit fees.
Construct validity of data from a TPACK self-assessment instrument in 2-year public college faculty in the United States

Abstract Mishra and Koehler’s technological pedagogical content knowledge (TPACK) theory can help provide the framework for measuring needed knowledge, skills, and abilities (KSAs) in faculty members at 2-year public colleges. This study tests a self-assessment survey in a large sample of 2-year public college faculty members. Using factor analysis, the Community College TPACK Survey for Meaningful Learning (CC-TSML) is found to demonstrate internal reliability, adequate model fit, and composite reliability. Use of this instrument can help faculty members and administrators determine what type of interventions may be necessary to help faculty achieve the needed KSAs as measured by the CC-TSML, including professional development.
Multi-Decadal Forest-Cover Dynamics in the Tropical Realm: Past Trends and Policy Insights for Forest Conservation in Dry Zone of Sri Lanka

Forest-cover change has become an important topic in global biodiversity conservation in recent decades because of the high rates of forest loss in different parts of the world, especially in the tropical region. While human interventions are the major cause, natural disasters also contribute to forest cover changes. During the past decades, several studies have been conducted to address different aspects of forest cover changes (e.g., drivers of deforestation, degradation, interventions) in different parts of the world. In Sri Lanka, increasing rates of forest loss have been recorded during the last 100 years on a regional basis, especially in the dry zone. However, Sri Lanka needs detailed studies that employ contemporary data and robust analytical tools to understand the patterns of forest cover changes and their drivers. The dry zone of Sri Lanka encompasses 59% of the total land area of the country, ergo, the most extensive forest cover. Our study analyzed forest cover dynamics and its drivers between 1992 and 2019. Our specific objectives included (i) producing a forest cover map for 2019, (ii) analyzing the spatiotemporal patterns of forest cover changes from 1992 to 2019, and (iii) determining the main driving forces. Landsat 8 images were used to develop forest-cover maps for 2019, and the rest of the forest cover maps (1992, 1999, and 2010) were obtained from the Forest Department of Sri Lanka. In this study, we found that the dry zone had undergone rapid forest loss (246,958.4 ha) during the past 27 years, which accounts for 8.0% of the net forest cover changes. From 2010 to 2019, the rates of forest loss were high, and this can be associated with the rapid infrastructure development of the country. The findings of this study can be used as a proxy to reform current forest policies and enhance the forest sustainability of the study area.
Anomaly traffic detection and correlation in Smart Home automation IoT systems

Smart building automation systems are increasingly the target of hacking attacks. Moreover, they may be used as a tool for attacks against targets located out of the native Home Area Network (HAN). These attacks are often resulted in changes in traffic volume, damaged packets, increased message traffic, and so on. Symptoms of attacks can be detected as anomalies in traffic model and recognized by a software agent run on Home Gateway. Although these anomalies are detected locally, it may help network provider to protect his resources as well as other resources of his clients. For that purpose, network operator should be able to recognize anomalies and correlate them on the network level. In this way, the network operator has the ability to protect both its own network and HANs of its clients. This article shows that Smart Home security might be coupled with the providers' network security policy. For that reason, security tasks should be performed both in HAN and providers' data center. This article describes a novel strategy for anomaly detection that provides shared responsibility between a service client and the network provider. It uses a machine learning approach for classifying the monitoring data and correlation in searching suspicious behavior across the network resources at the service provider's data center.
Late Cambrian to Early Silurian Granitic Rocks of the Gemuri Area, Central Qiangtang, North Tibet: New Constraints on the Tectonic Evolution of the Northern Margin of Gondwana

The Paleozoic tectonic framework and paleo–plate configuration of the northern margin of Gondwana remain controversial. The South Qiangtang terrane is located along the northern margin of Gondwana and records key processes in the formation and evolution of this supercontinent. Here, we present new field, petrological, zircon U‐Pb geochronological, and Lu‐Hf isotopic data for granitic rocks of the Gemuri pluton, all of which provide new insights into the evolution of the northern margin of Gondwana. Zircon U‐Pb dating of the Gemuri pluton yielded three concordant ages of 488.5 ± 2.1, 479.9 ± 8.9, and 438.5 ± 3.5 Ma. Combining these ages with the results of previous research indicates that the South Qiangtang terrane records two magmatic episodes at 502–471 and 453–439 Ma. These two episodes are associated with enriched zircon Hf isotopic compositions (∊Hf(t) = –10.1 to –3.9 and –16.6 to –6.5, respectively), suggesting the granites were formed by the partial melting of Paleoproterozoic–Mesoproterozoic metasedimentary rocks (Two–stage Hf model ages (TDMC) = 2094–1704 and 2466–1827 Ma, respectively). Combining these data with the presence of linearly distributed, contemporaneous Paleozoic igneous rocks along the northern margin of Gondwana, we suggest that all of these rocks were formed in an active continental margin setting. This manifests that the two magmatic episodes within the Gemuri area were associated with southward subduction in the Proto‐ (Paleo‐) Tethys Ocean.
Measuring Customer Satisfaction and Hotel Efficiency Analysis: An Approach Based on Data Envelopment Analysis

We propose a network DEA (Data Envelopment Analysis) model that consists of internal and external service processes and employs customer satisfaction as an intermediate factor. Using the proposed model, we calculate four efficiency scores: service productivity score drawn from internal service process, service efficiency score drawn from external service process, overall efficiency score drawn from both internal and external service processes, and management efficiency score calculated without the intermediate output. By analyzing the four efficiency scores, we find that overall efficiency score is well suited to represent a hotel’s comprehensive productivity. Our results support the validity of a network DEA model which includes customer satisfaction for analyzing hotel efficiency. Despite its important role that plays in hotel efficiency, customer satisfaction has been barely considered in the previous hotel efficiency studies. By analyzing hotel efficiency including customer satisfaction, this study sheds new light on the hotel efficiency research area and provides a valuable basis for future research.
Combining Ability and Gene Action Analysis for Seed Yield and Component Traits in F2 Generation of Vigna mungo L. Hepper by using Griffing Approach

Background: Urdbean (2n=2x=22), also known as blackgram is an important short duration legume crop belonging to family Fabaceae, widely cultivated in Asia. Urdbean occupies an important position among pulses owing to its high seed protein (25-26%), carbohydrates (60%), fat (15%), minerals, amino acids and vitamins. Owing to its low water requirement, it is also suitable for rainfed conditions. It adapts well to various cropping systems owing to its ability to fix atmospheric nitrogen in symbiosis with soil bacteria, rapid growth and early maturity. Half diallel analysis was adopted in present study to gather information on gca (general combining abilities) and sca (specific combining abilities) of 6 diverse parents and simultaneously estimating various types of gene effects involved in the expression of seed yield and related attributes in urdbean. Methods: The F1’s were developed during 2017 in 9 x 9 half diallel fashion by Sharma et al. 2019 and these F1’s were evaluated. Significant crosses on the basis of gene action and combining ability were selected for further advancement. The experimental material comprised of the six parents and 15 F2’s of a 6 x 6 half diallel cross among six cultivars of urdbean (four are purelines viz., Palampur-93, HPBU-111, DU-1 and KU-553 and rest of the two are advanced and indigenous lines viz., Him Mash-1 and IC-281994). The F2’s along with the parental genotypes were grown in a Randomized block Design (RBD) with three replications at Experimental Farm of the Department of Crop Improvement, COA, CSK HPKV Palampur (H.P.) during Kharif, 2018. Results: The cross combination, Him Mash-1× HPBU-111, was identified the best for high seed yield on the basis of sca. The specific crosses, Palampur-93 × IC-281994, Palampur-93 × KU-553 were good specific combiners for most of the traits viz., plant height, branches per plant, pods per plant, biological yield per plant, seed yield per plant, harvest index, 100-seed weight and crude protein content.
Land suitability assessment for Lansium domesticum cultivation on agroforestry land using matching method and geographic information system

Rahmawaty, Frastika S, Rauf A, Batubara R, Harahap FS. 2020. Land suitability assessment for Lansium domesticum cultivation on agroforestry land using matching method and geographic information system. Biodiversitas 21: 3683-3690. Lansium domesticum is one of the multipurpose tree species (MPTS) and is commonly found on agroforestry lands in Sumatra. This study aimed to evaluate the actual land suitability classes for L. domesticum and to map the potential land suitability for the species using matching method and geographic information system (GIS). The study was conducted in Sei Bingai Sub-district, Langkat District, North Sumatra, Indonesia. A survey was conducted to collect soil samples based on land units. Land unit information was obtained by overlaying soil map, land-use map, and slope map. Land suitability was evaluated based on the matching method and GIS was used to map the distribution of land suitability. The results showed that both the actual and potential land suitability classes based on matching approach for L. domesticum were moderately suitable (S2) which accounted for 88.95% of total land and marginally suitable (S3) which accounted for 11.05%. Availability of water (wa), erosion hazard (eh), root-zone medium (rc), oxygen availability (oa), and nutrient retention (nr) were the dominant limiting factors in this area. The most difficult constraints to manage were root-zone medium and water availability. The results of this study suggest that the development of L. domesticum in Sei Bingai is possible although it requires some land improvements to deal with the limiting factors.
