State University of Malang. Advisors : (I) Prof. Utami Widiati, M.A., Ph.D.,(II) Drs. Andi Muhtar, M.A. Key words: Word Wall Activities, vocabulary mastery In the preliminary study, the researcher found out that the students of 8D in SMPN P lacked vocabulary. The students' result on A Test of The First 1,000 Words of English that was adapted from Nation (1993) showed that none of the students (0%) could pass the minimum standard. The students should answer at least 33 items from 40 items. The research design that was used in this study is collaborative Classroom Action Research (CAR) which collaborated with the class teacher. The stages in Classroom Action Research that were used by the researcher were planning, acting, observing, and reflecting. The researcher conducted a preliminary study before those stages to identify the problem of the students. The subject of this study was eighth graders in 8D class. There are 27 students in the class. There were fourteen female students and 13 male students. The time allotment is 2x 40 minutes each meeting. The study was in 4 meetings. The data that was used to know the students' vocabulary mastery was the vocabulary test. Then, the researcher used observation checklist, questionnaire, field note and the teacher'statement to know the students' participation and opinion about Word Wall Activities. The researcher also conducted an interview with the the teacher to know the teacher's opinion about the implementation of Word Wall Activities in the class. Word wall acvtivities were activities that engage the students to learn about new words that was facilitated with word wall. Those words would help the students understand the material. Through these activitities, the students were also expected to memorize and expand the words. Then, the teacher would check the students' understanding about the words in the word wall by asking them to give meaning or make sentences about the words. After the implementation of Word Wall Activities, the researcher found out that Word Wall Activities were beneficial for the students and teacher. First, Word Wall Activities could improve students' vocabulary mastery. In the vocabulary test before the implementation of Word Wall Activities, the percentage of students who passed the test was 0%. Then, after the implementation of Word Wall Activitie, the percentage of students who passed the test became 63%. There were some steps that were used by the researcher that made Word Wall Activities could be implemented to improve the students' vocabulary mastery. First, the teacher provided ten new words in every meeting that would be useful for the students to understand the material that was given by the teacher. It made the students' aware of the importance of the words. Second, Word Wall Activity gave a chance for the students to use the words more often and expand the words. Third, word wall that was put in the classroom could be easily seen by the students. They could see the words during the lesson. This situation made them realize that those words would be beneficial for them to understand the lesson. Also, this made them familiar with the words and memorized the words that were posted on word wall. Fourth, the teacher also checked the students' understanding in every meeting about the words that has been learned by asking the meaning of some words or asking the student to make a sentence from the words on word wall. Second, the students' participation during the implementation of Word Wall in the class was in high number. The researcher provided interesting and enjoyable Word Wall Activities that engage the students' participation. Those activities made the students participate in the lesson bacause each student had a role in the Word Wall Activities.The mean of students' participation from 4 meeting was 90%. It was higher than the criteria of success that had been set by the researcher. Based on the students' answer in the questionnaire, most of the students said that the Word Wall Activities were fun and interesting. They could help them to understand more about the new words. Third, the English teacher stated that the implementation of Word Wall Activities was not so difficult. The teacher only needed to provided the new words that would help the students understand the material. Then, the teacher made the Word Wall Activities that were interesting and fun to make the students participated actively in the class. Finally, the teacher stated that she wanted to implement Word Wall Activities in the class. Based on the result of the study, the researcher has some suggestions. For the English teacher who wants to implement Word Wall Activities, the researcher suggests that Word Wall Activities should attract students' attention. For the students, the researcher suggests that they have to be more active in the class and follow the activities well. For other researchers who are going to conduct an action based research, the researcher suggested to apply more attractive Word Wall and various Word Wall Activities to improve the students' vocabulary mastery.ABSTRAK Fiani, Janati. 2017.

Machine Learning for Crack Segmentation from Photogrammetric Imagery
Get PDF2021 - 2022The aim of the study proposed in this thesis was to analyse and implement data pro-
cessing procedures and algorithms to try to overcome the criticalities present in the
traditional identification and segmentation of cracks on road pavements and buildings.
For this purpose, algorithms were implemented in Python in order to optimise, on
the one hand, the point cloud and products from the photogrammetric process and,
on the other hand, the crack segmentation methodology, which is currently the most
accurate in the literature.
Point clouds produced by photogrammetric software are not directly usable, as they
must first be processed to remove outliers and noise. The first phase of the thesis pre-
sents an innovative approach that can assist survey methods by applying an AI algo-
rithm to improve the accuracy of point clouds generated from UAV images.
Many studies on the semantic segmentation of cracks using Machine Learning and
Deep Learning techniques can be found in the relevant literature. However, this task is
very challenging due to the complexity of the background, as cracks are easily confused
with objects not belonging to the surface, shadows, and background textures and are
also inhomogeneous.
The results obtained to date are quite good, but often the accuracy of the trained
model and the results achieved are evaluated using traditional metrics only. In most
cases, the goal is merely to detect the occurrence of cracks. Particular attention should
be paid to the thickness of the segmented crack, as the width of the crack is the main
parameter for maintenance and characterizes the severity levels. The aim of our study
is to optimize the crack segmentation process through the implementation of a modi-
fied U-Net model-based architecture. U-Net is a network with two symmetrical
branches (encoder-decoder structure). The encoder is replaced with a ResNet50 en-
coder pre-trained on the ImageNet dataset. Our focus was on crack segmentation, and
for this purpose, we used the Crack500 Dataset and compared the results with those
obtained from the algorithm currently considered the most accurate and performant
in the literature.
To demonstrate the generalization of the model, two real case studies were tested
by performing a UAV survey to obtain the photogrammetric models of both.
The results are promising and accurate, with the shape and width of the segmented
cracks closely resembling reality. [edited by Author]XXXV cicl
Vehículos aéreos no tripulados para el levantamiento y monitoreo de áreas arqueológicas
Get PDF2016 - 2017The research focused on the analysis of the deviation that an aerofotogrammetric survey can produce with respect to the classic topographic surveys, by total station, GPS (Global Positioning System) or TLS (Terrestrial Laser Scanner), instruments with significantly higher sensitivity than the airborne system, and therefore affected by minor uncertainties. In the various applications, using topographic measurements from different systems and using the so-called GCP (Ground Control Point), the metric deviations between the geo-referenced photogrammetric model and the topographic support were calculated, evaluating the system’s metric potential in different configurations.
Moreover, by a script, the reprojection errors were measured for each point of the cloud generated by the entire photogrammetric process; from statistical analysis of the reprojection error in the various case studies, the modalities for which the aerofotogrammetric survey has the smallest deviations have been evaluated.
The elaborated case studies come essentially within the archaeological field, in which, in close contact with the various Sovraintendenze, the possible elaborations to be returned for an initial computerization of the survey were analyzed. The set of works produced and delivered to the various Sovraintendenze, represents the starting point for the conservation and preservation of the archaeological heritage, from which to obtain information for different areas of interest (degradation assessment, calculation of subsidence and / or deformations, etc…). The comparison with the classical topography is necessary for a metric comparison of the 3D model, from which all the elaborates will be derived (orthophotos, sections, level curves, etc.)...

The proteasome cap RPT5/Rpt5p subunit prevents aggregation of unfolded ricin A chain
Get PDFThe plant cytotoxin ricin enters mammalian cells by receptor-mediated endocytosis, undergoing retrograde transport to the endoplasmic reticulum (ER) where its catalytic A chain (RTA) is reductively separated from the holotoxin to enter the cytosol and inactivate ribosomes. The currently accepted model is that the bulk of ER-dislocated RTA is degraded by proteasomes. We show here that the proteasome has a more complex role in ricin intoxication than previously recognised, that the previously reported increase in sensitivity of mammalian cells to ricin in the presence of proteasome inhibitors simply reflects toxicity of the inhibitors themselves, and that RTA is a very poor substrate for proteasomal degradation. Denatured RTA and casein compete for a binding site on the regulatory particle of the 26S proteasome, but their fates differ. Casein is degraded, but the mammalian 26S proteasome AAA-ATPase subunit RPT5 acts as a chaperone that prevents aggregation of denatured RTA and stimulates recovery of catalytic RTA activity in vitro. Furthermore, in vivo, the ATPase activity of Rpt5p is required for maximal toxicity of RTA dislocated from the Saccharomyces cerevisiae ER. Our results implicate RPT5/Rpt5p in the triage of substrates in which either activation (folding) or inactivation (degradation) pathways may be initiated
Is the European Economy a Patient and the Union its Doctor? On Jobs and Growth in Europe. CEPS ENEPRI Working Papers No. 35, 1 April 2005
Get PDFA stronger focus on jobs and growth is part of an effort to renew the Lisbon strategy. Yet the view that economic expansion contributes to maintaining Lisbon’s other goals of social cohesion as well as the environment is somewhat optimistic. First, there are structural trade-offs among the central elements of the Lisbon strategy. Escaping these trade-offs temporarily is sometimes possible but requires policy changes. Second, higher productivity (growth) may not provide more structural room for governments to manoeuvre. It leads to higher tax receipts but also to higher public expenditures since public sector wages and social security benefits are linked to productivity. In contrast, more employment (jobs) is associated with a smaller public sector. But to engineer the increase in employment, changes in welfare state arrangements are needed. In other words, focussing solely on the sick child will probably harm the other children. Looking back, employment has kept expanding in the European Union whereas the productivity growth rate has been falling. The latter is not easily explained by (falling) investment in knowledge. Instead, the current relatively low productivity growth rate largely reflects success in the past: many European countries have caught up with the United States, having seen comparatively fast employment growth in the late 1990s. Looking forward, we argue that the combination of the Open Method of Coordination (OMC) with national action plans, the way the EU wants to achieve its goals, is both too little and too much: European interference with national employment polices has a weak basis, while the OMC may not provide member states with a strong enough commitment to pursue an innovation agenda
