Abstract:
Bisson (2001) proposes that imposition of form in Middle Palaeolithic scrapers can be recognized when the rules for scraper manufacture, which are based upon functional considerations, are known. He derives these ‘scraper production rules’ on the basis of experiments with novice flintknappers, and finds that they apply to Neanderthal-manufactured Mousterian scrapers. He interprets the violation of these rules in scrapers from Skhul Cave as evidence that anatomically modern humans imposed form on their stone tools, and therefore had mental templates. This study provides evidence that the ‘scraper production rules’ are not, in fact, the rules according to which Neanderthals made their tools. Instead, they reflect flaking mechanics and elements of Bisson's experimental design rather than any functional considerations taken into account during scraper manufacture. Furthermore, methodological flaws in Bisson's analysis of Middle Palaeolithic artefacts undermine his arguments that archaeological scrapers either follow or violate the rules. These problems render untenable his conclusion that Neanderthals did not have mental templates and that they lacked flexibility and innovation in stone-tool making.

Abstract:
A vertical type tandem twin roll caster equipped with a scraper for the clad strip was invented. This roll caster could cast three layers clad strip which base strip had lower melting point than that of the overlay strips. The base strip was cast by an upper twin roll caster and the overlay strips were cast by a lower twin roll caster. The scrapers were attached to the lower twin roll caster, and were innovated to cast this type of three layers of clad strip. Solidification layers those became the overlay strips were pulled from between the scraper and the roll. The melt of the alloy which was as same as the base strip was poured between the scraper and the base strip. This melt connect the overlay strip and the base strip. The base strip was not re-melted. The scraper enabled that the solidification layer of the overlay strip contact to the melt of the base strip without mixing of the melt of the base and overlay strip. In this way, the sound three layers clad strip which base strip had lower melting point than that of the overlay strip could be cast by the vertical type tandem twin roll caster equipped with a scraper.

Abstract:
Successful pig farming needs the best conditions of cleanliness in the housings. The present study examined for the first time whether a robot scraper usually applied in dairy farming is usable in sow housings for cleaning the slatted floors and improving hygiene and thus animal welfare. For evaluating the suitability of the robot scraper with regard to the cleaning performance (polluted surface area and occluded slots), the whole housing area was divided into score-squares, which were individually scored at defined intervals. Selected excrement quantities removed by the robot were weighed. In order to assess the animals’ interactions with the robot scraper, their behaviour towards the device was observed. Although the faeces of pigs had a firmer consistency than bovine excrement, excrement quantities of up to 1.4 kg m−2 were almost completely removed. Even 6 h after the cleaning its effect was still visible. Dry-cleaning led faster to nonslip surfaces for the sows than wet-cleaning. Within half an hour of observation, up to 8.2 of 120 sows were occupied with the robot scraper, but without harming it. The use of robot scrapers in pig housings is recommended, although slight technical modifications should be made to the robot scraper.

Abstract:
Denitrification in secondary clarifiers is primarily due to hydrolysis of particulate degradable COD and decay of biomass. The reduction factor of these processes under anoxic as compared to aerobic conditions was investigated in the treatment plants of the City of Zurich. The Zürich-Glatt plant has circular clarifiers with central inlet. The treatment plant Zürich-Werdhölzli has rectangular clarifiers with cross flow and scrapers with vacuum removal of the sludge. At Zürich Glatt denitrification capacity in the clarifiers was 30% of total denitrification, whereas at Zürich-Werdhölzli only 15 % was observed. The sludge mass in the secondary clarifier depends on inlet flow, return sludge flow, activated sludge concentration, sedimentation properties of the sludge and scraper intervals. During dry weather and due to good sedimentation properties the activated sludge blanket in the thickening zone of the rectangular clarifiers at Zürich-Werdhölzli is almost completely removed after passage of the scraper. Denitrification volume in the secondary clarifier can therefore be modelled in relation to the ratio of inlet to return sludge flow and scraper interval. With the aid of control of return sludge flow and scraper intervals denitrification capacity in the secondary clarifiers may be improved. In order to control denitrification in the secondary clarifier the model must include a variable sludge volume in the clarifier related to scraper interval under the assumption of constant sludge mass in the entire system.

Abstract:
Various lithic measures have been invoked to argue that human foragers moved over greater or lesser distances, or moved with greater or lesser frequency when compared with other foraging groups. This paper examines one of those measures—the reduction of blade end scrapers from early Upper Paleolithic Aurignacian and Perigordian occupations in southwestern France. Evidence of end scraper reduction is compared with faunal diversity and lithic material provenience, the former a potential catalyst of and the latter a potential reflection of mobility. A relationship between less-intense end scraper reduction, somewhat elevated percentages of distant raw materials, and reindeer-dominated fauna is noted during cold and apparently open environmental conditions. Less consistency in the extent of end scraper reduction is observed among assemblages associated with more diverse and at times less-mobile fauna. These observations argue for the importance of a fine-grained comparison of lithic and other data, the complexity of procurement strategies, and the recognition that greater or lesser reduction does not translate directly into greater or lesser mobility.

Abstract:
In this study, to investigate the performance characteristics of a seawater ice-making device, using a scraped surface double tube evaporator, experiments were conducted under various operating conditions, including inlet temperature and flow rate of seawater, evaporating temperature, and scraper rotation speed. The main results are summarized as follows: (1) The section where stable ice making is possible, is determined by the inlet temperature and the flow rate range of seawater. By controlling the flow rate of seawater, the ice packing factor (IPF) of the device can be adjusted from 0.3 to 14.7%. (2) The IPF increases in cases where the evaporating temperature decreases linearly, until −13 °C. As the temperature of refrigerant that flows into the evaporator changes, the IPF is changed. Consideration is required for these connections. (3) The IPF increases when speeding up the scraper. The minimum rotating speed of the scraper was 350 rpm in these experiments. Optimum operating conditions for the seawater ice slurry maker are established through experiments. These results will be considered as important data for designing a slurry type seawater ice-making device.

Abstract:
Sometimes in open mining, it is economically expedient to extract and transport rock mass with the help of wheel tractors-scrapers. To improve the hopper filling with the rock mass operating with clay or loosened rocks, it is advisable to use scrapers equipped with loading intensifiers in the form of a raking wall located inside the hopper. The article presents the experimental filling study results of wheel tractor-scraper hopper models of different capacities with a standard and increased hopper length at the presence or absence of a raking wall. The investigations were carried out on an experimental rock removal bench equipped with a strain gauge measuring system to record forces that arise during the hopper model filling with rock mass. Data are given on the rock mass removal for various filling methods, as well as for the resistance values for the piling wall movement and the energy capacity of the hopper filling process for operating with sandy loam, loam, clay, and limestone crushed stone. There were realized the calculations of the operational productivity and the specific cost of works, depending on the rock mass transportation distance with elongated hopper scrapers equipped with a scraper wall, scrapers with standard hoppers and scrapers operating with a pusher bulldozer set. The rational application areas for each of the machines were revealed.

Abstract:
Analysis of archaeological sites on a stream terrace system in Kansas supports the idea that spurred end scrapers are valid diagnostic Paleoindian artifacts. No sites with spurred end scrapers were discovered on the Holocene terraces, while the Wisconsin terraces did yield such sites. The differential distribution of spurred end scraper sites on terraces appears to be statistically significant. The results are consistent with the hypothesis that spurred end scrapers were not found on the Holocene terraces because they were not being used when the Holocene terraces formed.

Abstract:
Підвищені енергетичні витрати на транспортування, висока ступінь подрібнення зерна пов’язані з наявними недоліками існуючих конструкцій скребкових елеваторів з відцентровим типом розвантаження, є зворотне осипання (колова циркуляція) зерна. Для усунення цього недоліку необхідно проаналізувати фактори, що впливають на напрямок потоку вантажу залежно від його швидкості та положення натяжного пристрою. За результатами експериментальних досліджень ефективності роботи скребкових елеваторів встановлено залежність зворотного сипу зерна в елеваторі (колової циркуляції) від швидкості транспортування та сектору розвантаження. Запропоновано враховувати особливості роботи натяжного механізму скребкового елеватору на зернозбиральних комбайнах та дообладнати верхню частину елеватора додатковим направляючим кожухом. When transporting grain, the return fall and, respectively, partial crushing of grain by scrapers, a chain and asterisks of an elevator are observed. It is because of detected imperfection of an elevator’s head design combined with a tension device The correction of a trajectory of a grain flow is carried out by a cover of an upper part of an elevator. If the time of the movement of grain on an elevator scraper surface is equal or smaller than the time of rotation of a scraper when passing a zone of unloading, then we have a high probability of hit of layers of a grain flow in necessary limits, at the same time centrifugal unloading is successfully. If the trajectory of grain layers gets to a lower zone, then there is a possibility of grain entering in a single part of a scraper elevator that is, the return rash, circular circulation of grain in an elevator casing, is formed. Such phenomenon is negative as it involves additional power costs of transportation; increases crushing and compression damage of grain weight, accelerates wear of operating parts of the grain transport system of the combine. The next part of the research, devoted to the ways of improvement of centrifugal unloading in a scraper elevator, is optimization of size of the sector of unloading. For the solution of such task we have conducted a number of researches by means of special experimental installation. It is possible to change the sector of a zone of unloading by means of change of height of unloading zone. Speed of transportation of grain was different with the change of turns of a power shaft with an asterisk to a chain occasion with scrapers. According to the result of the experiment measurement of power parameters of grain transportation by a scraper elevator is taken, at the same time it is found out that reduction of circular circulation in an elevator from 7-10% to 2-3% of the general supply of grain gives the chance to save 0,075-0,085 kW of power costs of transportation with a productivity of elevator of 5-5,5 kg/s. To eliminate this drawback, it is proposed to install an of the additional directing casing in the upper part of the scraper elevator of the additional directing casing . To eliminate this drawback, it is proposed to install an additional directing body in the upper part of the scraper elevator.

Abstract:
In recent years, the act of scraping websites for information has become increasingly relevant. However, along with this increase in interest, the internet has also grown substantially and advances and improvements to websites over the years have in fact made it more difficult to scrape. One key reason for this is that scrapers simply account for a significant portion of the traffic to many websites, and so developers often implement anti-scraping measures along with the Robots Exclusion Protocol (robots.txt) to try to stymie this traffic. The popular use of dynamically loaded content – content which loads after user interaction – poses another problem for scrapers. In this paper, we have researched what kinds of issues commonly occur when scraping and crawling websites – more specifically when scraping social media – and how to solve them. In order to understand these issues better and to test solutions, a literature review was performed and design and creation methods were used to develop a prototype scraper using the frameworks Scrapy and Selenium. We found that automating interaction with dynamic elements worked best to solve the problem of dynamically loaded content. We also theorize that having an artificial random delay when scraping and randomizing intervals between each visit to a website would counteract some of the anti-scraping measures. Another, smaller aspect of our research was the legality and ethicality of scraping. Further thoughts and comments on potential solutions to other issues have also been included.

Abstract:
Scrapers are useful construction equipment when hauling distances range between 500 to 3000 feet. When preparing an estimate for an earthmoving project utilizing scrapers, the capacity of the scraper and the cycle time for the given project conditions must be calculated. Since travel time varies widely based on the conditions of the haul road and the performance of the equipment, determining the most economical selection (size and model) and the correct number of scrapers and pushers is a rather tedious process. The calculation of travel time between the cut and fill zone involves repetitive calculations. A spreadsheet-based interactive advisory system was created in order to facilitate these calculations and generate a list of recommended equipment. The system contains a scrapers database, performance charts, soil properties, and a user interface to solicit data that is specific to the project such as haul road surface conditions and characteristics. Data such as efficiency (minutes worked per hour) and hourly rates for operators and other workers can also be specified in the user interface. Once the user enters the quantity to be moved the application calculates the production rate, time required for the job, and the estimated unit cost for each scraper in the database. The system then produces a list of all scrapers, sorted in the order of shortest time or lowest unit price.

Abstract:
I en värld där alltmer information lagras på internet är det svårt för en vanlig användare att hänga med. Även när informationen finns tillgänglig på en och samma hemsida kan den hemsidan sakna funktioner eller vara svår att läsa av. Idén bakom att skrapa hemsidor, tidningar eller spel på information är inte ny och detta examensarbete fokuserar på att bygga en web scraper med tillhörande hemsida där användare kan ladda upp sitt schema skrapat från TimeEdit. Hemsidan ska sedan presentera denna skrapade data på ett visuellt tilltalande sett. När system är färdigutvecklade utvärderas dem för att se om examensarbetets mål har uppnåtts samt om systemen har förbättrat det befintliga sättet att hantera schemaläggning i TimeEdit hos lärare och studenter. I sammanfattningen finns sedan framtida forskning och arbeten presenterat.
The concept of scraping the web is not new, however, with modern programming languages it is possible to build web scrapers that can collect unstructured data and save this in a structured way. TimeEdit, a scheduling platform used by Mid Sweden University, has no feasible way to count how many hours has been scheduled at any given week to a specific course, student, or professor. The goal of this thesis is to build a python-based web scraper that collects data from TimeEdit and saves this in a structured manner. Users can then upload this text file to a dynamic website where it is extracted from the file and saved into a predetermined database and unique to that user. The user can then get this data presented in a fast, efficient, and user-friendly way. This platform is developed and evaluated with the resulting platform being a good and fast way to scan a TimeEdit schedule and evaluate the extracted data. With the platform built future work is recommended to make it a finishes product ready for live use by all types of users.

Abstract:
Web forums are a popular way of exchanging information and discussing various topics. These websites usually have a special structure, divided into boards, threads and posts. Although the structure might be consistent across forums, the layout of each forum is different. The way a web forum presents the user posts is also very different from how a news website presents a single piece of information. All of this makes the navigation and extraction of text a hard task for web scrapers. The focus of this thesis is the development of a web scraper specialized in forums. Three different methods for text extraction are implemented and tested before choosing the most appropriate method for the task. The methods are Word Count, Text-Detection Framework and Text-to-Tag Ratio. The handling of link duplicates is also considered and solved by implementing a multi-layer bloom filter. The thesis is conducted applying a qualitative methodology. The results indicate that the Text-to-Tag Ratio has the best overall performance and gives the most desirable result in web forums. Thus, this was the selected methods to keep on the final version of the web scraper.
Webforum är ett populärt sätt att utbyta information och diskutera olika ämnen. Dessa webbplatser har vanligtvis en särskild struktur, uppdelad i startsida, trådar och inlägg. Även om strukturen kan vara konsekvent bland olika forum är layouten av varje forum annorlunda. Det sätt på vilket ett webbforum presenterar användarinläggen är också väldigt annorlunda än hur en nyhet webbplats presenterar en enda informationsinlägg. Allt detta gör navigering och extrahering av text en svår uppgift för webbskrapor. Fokuset av detta examensarbete är utvecklingen av en webbskrapa specialiserad på forum. Tre olika metoder för textutvinning implementeras och testas innan man väljer den lämpligaste metoden för uppgiften. Metoderna är Word Count, Text Detection Framework och Text-to-Tag Ratio. Hanteringen av länk dubbleringar noga övervägd och löses genom att implementera ett flerlagers bloom filter. Examensarbetet genomförs med tillämpning av en kvalitativ metodik. Resultaten indikerar att Text-to-Tag Ratio har den bästa övergripande prestandan och ger det mest önskvärda resultatet i webbforum. Således var detta den valda metoden att behålla i den slutliga versionen av webbskrapan.

Abstract:
This master thesis have been done to come up with different concepts that could solve problems that is connected to vibrations in tandem rollers. The main problem is that the vibrations makes it harder to remove asphalt with the built in scraper, creating an uneven contact with the drum and the scraper. The new concepts should improve the machines ability to remove asphalt and decrease the amount of maintenance that is needed. To understand what the new tool needs to do some functional analyses have been done. To create new concepts the triz method have been used. The different concept was evaluated with a pugh matrix and swot. In the final part the focus is on how the best concept could become better. The final concept locks the scraper geometrically so it moves the same way as the drum. This makes it so it always are at the same distance to the drum.
Den här uppsatsen handlar om olika koncept som kan lösa problem som är kopplade till vibrationer från tandem vältar. Huvudproblemet som har varit i fokus är att vibrationerna från valsen försvårar möjligheten att ta bort asfalt med den inbyggda skrapan. Detta ger en ojämn kontakt mellan skrapan och valsen. De nya koncepten borde förbättra maskinen förmåga att ta bort asfalt och minska det nödvändiga underhållet. För att förstå vad det nya verktyget behöver göra har det gjort funktionsanalyser. För att genera nya koncepts har verktyget triz använts. De olika konceptet har utvärderats med en pugh matris och swot metoden. Sista delen av arbetet handlar om hur den bästa konceptet kan bli bättre. The slutgiltiga förslaget går ut på att man låser skrapa geometriskt så att den rör sig på samma sätt som valsen. Detta gör att den alltid håller sig på samma avstånd till valsen.

Abstract:
UA Open Access Publishing Fund
While predetermined de´bitage technologies are recognized beginning with the middle Acheulian, the Middle Paleolithic is usually associated with a sharp increase in their use. A study of scraper-blank technology from three Yabrudian assemblages retrieved from the early part of the Acheulo-Yabrudian complex of Tabun Cave (ca. 415–320 kyr) demonstrates a calculated and preplanned production, even if it does not show the same complexity and elaboration as in the Levallois technology. These scraper dominated assemblages show an organization of production based on an intensive use of predetermination blank technology already in place at the end of the Lower Paleolithic of the Levant. These results provide a novel perspective on the differences and similarities between the Lower and Middle Paleolithic industries. We suggest that there was a change in the paradigm in the way hominins exploited stone tools: in many Middle Paleolithic assemblages the potential of the stone tools for hafting was a central feature, in the Lower Paleolithic ergonometric considerations of manual prehension were central to the design of blanks and tools.

Abstract:
Due to the outbreak of the Covid-19 pandemic, college tours are no longer available, so many students have lost the opportunity to see their dream school’s campus. To solve this problem, we developed a product called “Virtourgo,” a university virtual tour website that uses Google Street View images gathered from a web scraper allowing students to see what college campuses are like even when tours are unavailable during the pandemic. The project consists of 3/4 parts: the web scraper script, the GitHub server, the Google Domains DNS Server, and the HTML files. Some challenges we met include scraping repeated pictures and letting the HTML dropdown menu jump to the correct location. We solved these by implementing Python and Javascript functions that specifically target such challenges. Finally, after experimenting with all the functions of the web scraper and website, we confirmed that it works as expected and can scrape and deliver tours of any university campus or public buildings we want.

Abstract:
Abstract This paper deals with the dynamic characteristics of scraper-discharge material centrifuge. The bowl center of gravity and the critical speed of rotor system have been calculated. Both One- and Two-plane field dynamic balancing methods suitable for this type of centrifuge are nalyzing. The design of isolator used with this type of centrifuge is also discussed since severe vibrations have developed during the operation. In traditional isolator design, transmissibility is obtained by extracting root of the differential equation for the multi-degree freedom system which is an elaborate method. In this paper, the transmissibility is obtained by the impedeance analysis method. The calculations are simple and agree well with the experimental results.

Full text
Abstract:
Ensiferan insects (crickets, katydids, grigs and allies) are well known for rubbing parts of their cuticle together to produce sound: a process called stridulation. In this article Swedish entomologist Kjell Ander describes a novel (at the time) stridulatory apparatus in the great grig, Cyphoderris monstrosa (Prophalangopsidae), a relict ensiferan found in the mountainous regions of western North America. Ander used preserved specimens to predict the sound-producing function of a pair of abdominal file-scraper apparatuses, although he was never able to directly test his proposed mechanism nor did he speculate as to the adaptive significance of the structures. The article concludes with a review of the systematic placement of various higher level taxa within the order Orthoptera, of which Ensifera is one suborder.
