Full textAbstract:
The following article presents an approach for a novel positioning stage as basic component of a small machine tool. It is a parallelkinematic machine (BiGlide mechanism), which converts the linear motion of two linear axes into a planar motion. The novel features, which were identified to be crucial for the transition from conventional machine tools to small ones, are: compact and precise feed axes, backlash free motion transmission, and direct measurement of the tool-center-point position and the ability of additional fine positioning. The proposed implementations are: hydraulic feed units, dry slide bearings as rotational joints, highly precise radar sensors and active variable-length struts of the parallelkinematic machine. Some of the simulation results are presented along with measurements of a currently designed prototype.

в статье анализируются статистические данные, полученные на основе анкетирования абитуриентов, приходящих в вузы на дни открытых дверей. При анализе сделан акцент на художественные выставки, которые смогут показать не только направления и стили живописи, но и сориентировать абитуриента в том, какие компетенции формируют в процессе обучения в вузе, и в том, готов ли он обучаться в данном вузе. Для привлечения абитуриентов в вузы художественно-эстетической направленности раскрыты инструменты маркетинга и обращено особое внимание на таргетированность, индивидуализацию и персонификацию коммуникаций. Для позиционирования вуза использованы средства PR: издание методической и научной литературы, участие в мастер-классах, конференциях и творческой деятельности. Особое внимание обращено на такие инструменты маркетинга, которые способствуют продвижению выставочной деятельности в вузе и привлечению экспонентов и абитуриентов к сотрудничеству с вузом. Высказан ряд предложений по позиционированию вуза на основе внедрения выставочной деятельности. В частности: определен интерес абитуриентов к тематике выставок, поэтому перед организацией выставки нужно готовить экспонента к правильному оформлению выставки; по окончании выставки проводить конференции с абитуриентами по обмену мнениями и мастер-классы под руководством экспонента; изготавливать бейдж с логотипом вуза для экспонента и абитуриента-посетителя выставки; материализовать выставку в виде буклета; вручать диплом экспонентам и сертификат посетителям выставки; издавать журнал с репродукциями картин художника и его биографией; пользоваться услугами байера. the article analyzes statistical data obtained from a survey of applicants coming to universities for open days. The analysis focuses on art exhibitions that can show not only the directions and styles of painting, but also orient the applicant in what competencies are formed during the process of studying at a university, and whether he is ready to study at this university. To attract applicants to universities of artistic and aesthetic orientation, marketing tools are revealed and special attention is paid to targeting, individualization and personification of communications. PR means were used to position the university: publication of methodological and scientific literature, participation in master classes, conferences and creative activities. Particular attention is paid to marketing tools that help promote exhibition activities at the university and attract exhibitors and applicants to cooperate with the university. A number of proposals were made for positioning the university based on the introduction of exhibition activities. In particular: the interest of applicants in the topics of exhibitions has been determined, therefore, before organizing the exhibition, it is necessary to prepare the exhibitor for the correct design of the exhibition; at the end of the exhibition, hold conferences with applicants to exchange opinions and master classes under the guidance of the exhibitor; produce a badge with the university logo for the exhibitor and applicant-visitor of the exhibition; materialize the exhibition in the form of a booklet; present diplomas to exhibitors and certificates to exhibition visitors; publish a magazine with reproductions of the artist’s paintings and his biography; use the services of a buyer.

With many different studies showing a growing demand for the development of indoor positioning systems, numerous positioning and tracking methods and tools are available for which can be used for mobile devices. Therefore, an interest is more on development of indoor positioning and tracking systems that are accurate and effective. Presented and proposed in this work, is an indoor positioning system. As opposed to an Ad-hoc Positioning System (APS), it uses a Wireless Mesh Network (WMN). The system makes use of an already existing Wi-Fi infrastructure technology. Moreover, the approach tests the positioning of a node with its neighbours in a mesh network using multi-hopping functionality. The positioning measurements used were the ICMP echos, RSSI and RTS/CTS requests and responses. The positioning method used was the trilateral technique, in combination with the idea of the fingerprinting method. Through research and experimentation, this study developed a system which shows potential as a positioning system with an error of about 2 m to 3 m. The hybridisation of the method proves an enhancement in the system though improvements are still required.

In this paper we argue that both internal and external pressures and conditions urge contemporary higher education institutions to carefully think through their institutional profiles positions in domestic and global higher education contexts. We subsequently analyse strategic positioning from the strategic management literature and offer four tools — mapping, multi-dimensional ranking, benchmarking and degree profiling — to assist higher education institutions in their profiling and positioning strategies.

Full textAbstract:
In order to solve the problems of low positioning accuracy and poor stability of indoor electric power tools positioning technology in practical applications, this paper proposes a spatial positioning algorithm based on active Radio Frequency Identification (RFID). The algorithm first uses the Received Signal Strength Indicator (RSSI) ranging model to convert the signal strength of the target position to the distance from the target position to the locator, then obtains more accurate position information through the multilateral positioning model, and finally reduces the positioning error through the least squares estimation algorithm. In addition, a localization software system is designed for the algorithm, which displays the target's position and detailed coordinate information on top of the system interface, providing an intuitive display for indoor localization. The experimental results show that the algorithm can meet the basic needs of indoor positioning of electric apparatus, and the designed positioning software system can accurately display the position coordinates of electric apparatus.

Full textAbstract:
The positioning error of ultra-precision machine tools is the primary factor directly affecting the machining accuracy. It mainly depends on the machine tools guide. And its variation trend contains the same inertia as that of the machine tools movement. The variation trend of the positioning error is the derivative of a function fitted with the positioning errors of three adjacent testing points. The variation trends function is fitted with the variation trend of many points. The model of positioning error is the integral of the variation trends function. Because the variation trend of positioning error has certain inertia, the model of positioning error which is obtained in this way is more precise and more reliable than error function model which is directly fitted with limited discrete data.

Full textAbstract:
Olika navigeringstekniker är något som människan använder sig av dagligen. Det är och har varit en viktig del genom tiderna, i början handlade det om att kunna navigera till havs med hjälp av stjärnorna och idag har många människor i världen någon form av smarttelefon som kan användas som navigeringsverktyg. Inomhuspositionering är något som har blivit ett hett ämne den senaste tiden och eftersom GPS fungerar sämre inomhus har nya tekniker utvecklats för att navigera och positionera sig inomhus. De tekniker som ligger i framkant nu är bland annat Bluetooth Low Energy (BLE) och Wi-Fi där man med hjälp av triangulering kan positionera ut en användare inomhus. Frågan återstår då, vilket positioneringsverktyg är då lämpligt för inomhuspositionering. Detta examensarbete har utförts med en kombination av strategier. Som börjar med en jämförelsestudie av tre olika positioneringstekniker, BLE Wi-Fi och GPS, för att ta fram en lämplig positioneringsteknik för utvärdering i form av ett experiment där flera faktorer, främst precisionen, testas. I denna studie användes BLE beacons som positioneringsverktyg dels för att den var lätt att implementera men även för att den skulle uppnå hög precision. För att testa BLE beacon utvecklades en lätt applikationsprototyp som hade som huvudsyfte att kunna positionera ut en användare i ett koordinatsystem med hjälp av XYvärden. Genom att triangulering användes för att kunna positionera ut en användare uppnådde studien en medelmarginal på ungefär 76 centimeter när fem stycken beacons användes i ett område på 4 x 3 meter, vilket vi ansåg som godkänt för att kunna dra slutsatsen att BLE beacon är ett lämpligt verktyg när det kommer till en inomhuspositionering. Slutsatsen blev även att det skiljer sig avsevärt mycket i precision om man använder sig av för få eller helt enkelt dåligt placerade beacons.<br>Different navigation techniques are something that people uses on a daily basis. It has been and still is an important part in the history of mankind, initially navigation was about being able to navigate at sea using the stars, and today many people around the world have some kind of smartphone that can be used as a navigation tool. Indoor positioning is something that has become a hot topic in the last decade and since GPS has bad precision indoors new technologies has been developed to navigate and position objects indoors. Some leading technologies now includes Bluetooth Low Energy beacons and Wi-Fi, where you can position a user indoors using triangulation-techniques. The question still remains, which technique is viable for indoor positioning. This study has been conducted as a combination of two strategies, starting with a comparison study of three different positioning techniques, BLE, Wi-Fi and GPS, to come to a conclusion which positioning technique is suitable for indoor positioning. After the conclusion we evaluated the technique in the form of an experiment in which several factors, mainly the precision, are tested. In this study, BLE beacon were used as the positioning tool because it was easy to implement but also to able to achieve high precision in the right environment. To test the beacons, a light application prototype was developed that had the main purpose of positioning a user in a coordinate system using XY values. By using triangulation to position the user. The study achieved a mean margin of approximately 76 centimeters when five beacons were used in a 4 x 3 meter area. The conclusion was BLE beacons is a suitable tool when it comes to indoor positioning and that there is a lot of difference in precision when using too few or poorly placed beacons.

Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2015.<br>Recently, the deployment and availability of wireless technology have led to the development of location and positioning services. These Location Based Services (LBSs) are attracting the attention of researchers and mobile service providers. With the importance of ubiquitous computing, the main challenge seen in the LBS is in the mobile positioning or localization within reasonable and certain accuracy. The Global Positioning System (GPS), as a widely known and used navigation system, is only appropriate for use in outdoor environments, due to the lack of line-of-sight (LOS) in satellite signals that they cannot be used accurately inside buildings and premises. Apart from GPS, Wi-Fi is among others, a widely used technology as it is an already existing infrastructure in most places. This work proposes and presents an indoor positioning system. As opposed to an Ad-hoc Positioning System (APS), it uses a Wireless Mesh Network (WMN). The system makes use of an already existing Wi-Fi infrastructure.

Full textAbstract:
Advanced manufacturing machinery is a corner stone of essential industries of technologicallydeveloped societies. Their accuracy permits the production of complexproducts according to tight geometric dimensions and tolerances for high efficiency,interchangeability and sustainability. The accuracy of advanced manufacturingmachinery can be quantified by the performance measure of positioning accuracy.Positioning accuracy measures the closeness between a commanded and an attainedposition on a machine tool or industrial manipulator, and it is ruled by lawsof physics in classical mechanics and thermodynamics. These laws can be applied tomodel how much the machinery deflects due to gravity, expands due to a change intemperature and how much and how long it vibrates due to process forces; hence,one can quantify how much the accuracy decreases. Thus, to produce machinerywith ever higher accuracy and precision one can design machines which deflect,expand and vibrate less or one can understand and model the actual behaviour ofthe machinery to compensate for it.This licentiate thesis uses physics-based modelling to quantify the positioningaccuracy of machine tools and industrial robots. The work investigates the potentialincrease in positioning accuracy because of the simultaneous modelling of the kinematics,static deflections, vibrations and thermo-elasticity as a lumped-parametermodel of the machinery. Consequently the models can be used to quantify thechange of the accuracy throughout the workspace.The lumped parameter models presented in this work require empirical modelcalibration and validation. The success of both, calibration and validation, dependson the availability of the right measurement instruments, as these need to be ableto capture the actual positioning accuracy of machinery. This thesis focuses on theimportance of measurement instruments in industry and metrology and creates acatalogue of requirements and trends to identify the features of the measurementinstruments required for the factories of the future. These novel measurement instrumentsshall be able to improve model calibration and validation for an improvedoverall equipment effectiveness, improved product quality, reduced costs, improvedsafety and sustainability as a result of physics-based modelling and measurementof advanced manufacturing machinery.

Esta tesis doctoral llevó a cabo el estudio, desarrollo e implementación de algoritmos para la navegación con
sistemas globales de navegación por satélite (GNSS), enfocándose en la determinación precisa de la posición,
velocidad y aceleración usando GPS, en modo post-procesado y lejos de estaciones de referencia.
Uno de los objetivos era desarrollar herramientas en esta área y hacerlas disponibles a la comunidad GNSS. Por ello
el desarrollo se hizo dentro del marco del proyecto preexistente de software libre llamado GPS Toolkit (GPSTk). Una
de las primeras tareas realizadas fue la validación de las capacidades de la GPSTk para el procesado del
pseudorango, realizando comparaciones con una herramienta de procesamiento de datos probada (BRUS).
La gestión de datos GNSS demostró ser un asunto importante cuando se intentó extender las capacidades de la
GPSTk al procesamiento de datos obtenidos de las fases de la señal GPS. Por ello se desarrollaron las Estructuras
de Datos GNSS (GDS), que combinadas con su paradigma de procesamiento aceleran el proceso de desarrollo de
software y reducen errores.
La extensión de la GPSTk a los algoritmos de procesado en fase se hizo mediante la ayuda de las GDS,
proporcionándose importantes clases accesorias que facilitan el trabajo. Se implementó el procesado de datos
Precise Point Positioning (PPP) con ejemplos relativamente simples basados en las GDS, y al comparar sus
resultados con otras aplicaciones de reputación ya establecida, se encontró que destacan entre los mejores.
También se estudió cómo obtener la posición precisa, en post-proceso, de un receptor GPS a cientos de kilómetros
de la estación de referencia más cercana y usando tasas de datos arbitrarias (una limitación del método PPP). Las
ventajas aportadas por las GDS permitieron la implementación de un procesado semejante a un PPP cinemático
basado en una red de estaciones de referencia, estrategia bautizada como Precise Orbits Positioning (POP) porque
sólo necesita órbitas precisas para trabajar y es independiente de la información de los relojes de los satélites GPS.
Los resultados de este enfoque fueron muy similares a los del método PPP cinemático estándar, pero
proporcionando soluciones de posición con una tasa mayor y de manera más robusta.
La última parte se enfocó en la implementación y mejora de algoritmos para determinar con precisión la velocidad y
aceleración de un receptor GPS. Se hizo énfasis en el método de las fases de Kennedy debido a su buen
rendimiento, desarrollando una implementación de referencia y demostrando la existencia de una falla en el
procedimiento propuesto originalmente para el cálculo de las velocidades de los satélites. Se propuso entonces una
modificación relativamente sencilla que redujo en un factor mayor que 35 el RMS de los errores 3D en velocidad.
Tomando ideas de los métodos Kennedy y POP se desarrolló e implementó un nuevo procedimiento de
determinación de velocidad y aceleración que extiende el alcance. Este método fue llamado Extended Velocity and
Acceleration determination (EVA). Un experimento usando una aeronave ligera volando sobre los Pirineos mostró
que tanto el método de Kennedy (modificado) como el método EVA son capaces de responder ante la dinámica de
este tipo de vuelos.
Finalmente, tanto el método de Kennedy modificado como el método EVA fueron aplicados a una red en la zona
ecuatorial de Sur América con líneas de base mayores a 1770 km. En este escenario el método EVA mostró una
clara ventaja tanto en los promedios como en las desviaciones estándar para todas las componentes de la velocidad
y la aceleración.<br>This Ph.D. Thesis focuses on the development of algorithms and tools for precise GPS-based position, velocity and
acceleration determination very far from reference stations in post-process mode.
One of the goals of this thesis was to develop a set of state-of-the-art GNSS data processing tools, and make them
available for the research community. Therefore, the software development effort was done within the frame of a
preexistent open source project called the GPSTk. Therefore, validation of the GPSTk pseudorange-based processing
capabilities with a trusted GPS data processing tool was one of the initial task carried out in this work.
GNSS data management proved to be an important issue when trying to extend GPSTk capabilities to carrier phasebased
data processing algorithms. In order to tackle this problem the GNSS Data Structures (GDS) and their
associated processing paradigm were developed. With this approach the GNSS data processing becomes like an
assembly line, providing an easy and straightforward way to write clean, simple to read and use software that speeds
up development and reduces errors.
The extension of GPSTk capabilities to carrier phase-based data processing algorithms was carried out with the help
of the GDS, adding important accessory classes necessary for this kind of data processing and providing reference
implementations. The performance comparison of these relatively simple GDS-based source code examples with
other state-of-the art Precise Point Positioning (PPP) suites demonstrated that their results are among the best.
Furthermore, given that the GDS design is based on data abstraction, it allows a very flexible handling of concepts
beyond mere data encapsulation, including programmable general solvers, among others.
The problem of post-process precise positioning of GPS receivers hundreds of kilometers away from nearest
reference station at arbitrary data rates was dealt with, overcoming an important limitation of classical post-processing
strategies like PPP. The advantages of GDS data abstraction regarding solvers were used to implement a kinematic
PPP-like processing based on a network of stations. This procedure was named Precise Orbits Positioning (POP)
because it is independent of precise clock information and it only needs precise orbits to work. The results from this
approach were very similar (as expected) to the standard kinematic PPP processing strategy, but yielding a higher
positioning rate. Also, the network-based processing of POP seems to provide additional robustness to the results,
even for receivers outside the network area.
The last part of this thesis focused on implementing, improving and testing algorithms for the precise determination of
velocity and acceleration hundreds of kilometers away from nearest reference station. Special emphasis was done on
the Kennedy method because of its good performance. A reference implementation of Kennedy method was
developed, and several experiments were carried out. Experiments done with very short baselines showed a flaw in
the way satellite velocities were computed, introducing biases in the velocity solution. A relatively simple modification
was proposed, and it reduced the RMS of 5-min average velocity 3D errors by a factor of over 35.
Then, borrowing ideas from Kennedy method and the POP method, a new velocity and acceleration determination
procedure named EVA was developed and implemented that greatly extends the effective range. An experiment using
a light aircraft flying over the Pyrenees showed that both the modified-Kennedy and EVA methods were able to cope
with the dynamics of this type of flight. Finally, both modified-Kennedy and EVA method were applied to a challenging
scenario in equatorial South America, with baselines over 1770 km, where EVA method showed a clear advantage in
both averages and standard deviations for all components of velocity and acceleration.

Full textAbstract:
The formal governance structure is more complex in trade unions than in many other organizations. Trade union researchers have drawn attention to the tensions between union administrative and representative systems and the fact that control in unions is bi-directional from leaders to members (through formal control systems), and from members to leaders (through democratic structures). This study has shown that the utilization of market orientation methods has the capacity to strengthen the administrative system without interfering with or being hindered by the representative system. The findings related to market orientation methods presented in this thesis are not of such a character that they can be deemed to be specific for trade unions. Therefore, as a general rule, market orientation methods need no trade union-specific adaptation to be utilized. The setting for this study is Sif, a major industrial white-collar trade union in Sweden. The change process of Sif described in the thesis suggests an increased degree of market orientation. The study has focused on two specific tools/techniques; The Sif Barometer - an annual membership satisfaction survey, and The Design Dialogue Methodology – an internally developed group interview method. These methods have contributed to an enhanced level of market orientation. Propositions for better contributions to strategic positioning and service innovation are presented in terms of design principles. An identified problem is that the potential for double-loop learning has been limited in the organization. Some propositions for enhancing double-loop learning are set out: Knowledge enhances learning: the utilization of market information requires knowledge among managers and employees about the instruments used to ensure accurate interpretations and utilization of the results acquired. Knowledge thus has a role in breaking down the barriers preventing accurate utilization of market information. Task alignment is a viable strategy for the creation of learning micro-climates: Learning through the change of work behaviors is the core element of a task alignment strategy. Task alignment is a strategy targeting learning capabilities in the organization that is not only an approach for solving problems in the long term, but also an immediate response to tangible business problems. Action research may contribute to double-loop learning: The action research method has inherent change properties connected to its "learning by change" approach. Actors should consider the discrepancies between espoused theories and theories-in-use: Various political behaviors hampering double-loop learning have been traced. A broad level of participation and involvement of managers and employees during the development or adaptation of the market orientation instrument can enable open and trustful discussions for enhancing double-loop learning.<br>Diss.

Abstract
Manufacturers are under tremendous pressure to improve product quality in terms of dimension while maintaining high productivity. To maintain product quality, it is necessary to know the accuracy level of machine tools so that defective parts can be prevented in manufacturing. Different machine tools deviate from their ideal situation to an error prone state over time. Even new machine tools may cause errors due to faulty installation, an extra heat source etc.
Roll, pitch and yaw errors are common problems in machine tools for the manufacturing industries. The origins of these errors are kinematics parameter deviations resulting from manufacturing errors, assembly errors or quasistatic errors. By considering the geometric description of any machine tool, one should be able to predict the actual tool tip as compared to ideal tool tip for every controlled point in the machine's workspace. By counting the forward kinematics of the machine it is possible to predict the tool tip deviation for every point. A number of measuring methods can be adopted to describe the actual geometry of machine tools. Each method has it's own advantages and disadvantages. Often machine tool experts measure the machine with different types of measuring devices to obtain error traces based on its error sources and magnitude.
In this thesis, a theoretical and practical relation has been established between static and dynamic measuring systems. These relations are important when we are measuring machine tools with different measuring devices to validate the measurement results. In this work, traces obtained by one measuring system have been compared and simulated with the traces obtained by other methods. A number of systematic mathematical models have been developed, and compared with the results obtained by other measuring methods. The outcome of this can lead to the development of a software system that can be used to validate measuring results obtained from different measuring systems and those can be compared with each other. The VM182 measurement result simulates closer than the laser measurement result when both are compared using the traces obtained by DBB measurement.
Several methods for improving the positioning accuracy of machine tools have been studied. One of the methods is NC code modification. This method has been applied to develop an NC program processor based on the error found by the measurements. An aluminium test piece has been cut with the modified program to test the developed model. The finding of NC code modification is that for repeatable error, we can obtain a better dimensional accuracy for work pieces when we use a modified NC program based on the algorithms developed. The arch replacement technique has given a circularity improvement from 22 to 12 with DBB measurement, and circularity has been improved from 12.59 to 8.10 when it has been applied to cut aluminium work piece.

The task performed in this assignment is to improve the reliability of Norden Machinery ABs product family. This is to be done by examining and replacing the belt used to stop the spreading of tubes from ingoing shipping crate to the infeed of the machine. The way that this was approached was by testing different candidates on a spectrum of their rigidity to find if a flexible or more rigid belt would perform better than the current context of the system. The testing was conducted for a period of 4 weeks and results were gathered by examining damages to the belts by the use of microscope. After the damage had been analyzed the conclusion was drawn that flexible alternatives seems to perform the task better than their rigid counterparts however more work is needed in the fields regarding the fastening and operation of the machine to use the best suited candidates derived from this test, the monolithic belt FMT-02TXCT-U1.

Foram implementados algoritmos robustos de filtragem para preparar o

obtidos mostram um melhoramento significativo em todas as situações
analisadas. Foi desenvolvido o software necessário para o efeito e
criadas soluções computacionais eficientes. As soluções computacionais
desenvolvidas foram integradas num software standard de
processamento de sísmica (SPW) utilizado na indústria, de forma a criar,
conjuntamente com as ferramentas já existentes, um workflow de

aquisição e controle de qualidade à produção dos volumes sísmicos
migrados pre-stack em profundidade.<br>Ocean bottom recording of 3D/4D multichannel seismic reflection data
using 4 component Nodes is a recent and growing major segment in the
marine seismic acquisition market in the oil and gas industry. These data
provide high quality subsurface imaging with low ambient noise levels,
broad bandwidth, wide azimuth illumination, long-offset, high resolution,
and recordings of both P and S waves. In addition, data acquisition is
highly repeatable and therefore ideal for 4D surveys. However, there are
significant differences in acquisition geometry and wavefield sampling,
compared to the conventional towed streamer data, which require new
tools to be developed for data processing. This thesis investigates three
key issues in OBS/NODE data processing that have not yet been
satisfactorily fully solved: random clock drifts, accurate OBS positioning
and efficient 3D pre-stack depth migration algorithms for accurate
subsurface imaging. New procedures were developed to tackle these
issues and these were tested on synthetic and real datasets. A new
method for random clock drift was created using high order derivatives to
detect and correct these residual drifts. A new accurate OBS/NODE
positioning algorithm, using multilateration was developed. Tools were
created for interpolation/extrapolation of 3D velocity functions across the
full extent of the acquisition survey, and robust smoothing algorithms
were used to prepare the velocity field to be used for ray tracing and prestack
3D Kirchhoff depth migration, so as to minimize migration artifacts.
The results obtained show a clear improvement in all situations analyzed.
Dedicated software tools were created and computationally efficient
solutions were implemented. These were incorporated into an industry
standard seismic processing software package (SPW), so as to provide,
together with the already existing tools, a fully integrated processing
workflow for OBS/NODE data, from data acquisition and quality control,
to the production of the final pre-stack depth migrated seismic volumes.

In Lecture Notes in Mechanical Engineering. Springer International Publishing, 2023. http://dx.doi.org/10.1007/978-3-031-28839-5_18.
Full textAbstract:
AbstractFriction, electrical losses, cooling systems and ambient conditions influence the thermal field of machine tools and cause a significant amount of positioning inaccuracies and production errors. Compensation strategies aim to reduce the thermal error in machine tools. The global urgency for energy-efficient production also affects the selection of specific compensation strategies, especially since some of them consume significant amounts of energy while others are potential energy savers. As of today, there is no method to select the optimal compensation strategy for thermal errors in machine tools. The main reasons are that the quality of any compensation strategy depends heavily on the examined machine tool and its intended usage. Besides this, there are several, often conflicting assessment criteria.This paper provides an overview of existing compensation strategies and presents an evaluation of their effect on the energy consumption. The investigated strategies comprise methods for reducing the heat losses, for decreasing the sensitivity of the tool center point to thermal influences, cooling strategies for removing heat from the machine tool, air conditioning and methods for controllable heat transfer and also various computational methods aimed at predicting and correcting the existing thermal positioning error in the machine tool control.As an addition to previous research, the rating of thermal error compensation strategies was extended by their effect on energy efficiency. The authors demonstrate that accuracy and energy efficiency must be considered jointly for each individual machine tool and manufacturing task.

Full textAbstract:
Digital annotation tools (DATs) are one of the recent digital platforms in which multiple users can read and annotate a shared document. Scholars have explored the use and impacts of DATs on peer interaction and documented that collaborative annotation enables a more learner-centered academic space where students can facilitate peer learning and socialization. The present study, on the other hand, shifts the focus and explores the roles of peer interaction to document three multilingual doctoral students’ micro-level positioning identities in a semester-long DAT activity. The study’s data involved students’ collaborative annotations on 11 scholarly articles, semi-structured interviews, and demographic information questionnaires. The data were analyzed with discourse analysis techniques. Findings indicate that students’ previous teaching experiences, linguistic and educational backgrounds, and research interests shaped their annotation behaviors and discursive choices and thus led to taking different positioning identities. The study offers pedagogical implications that might cultivate and foster quality peer interaction and involvement in collaborative DAT activities.

This study concentrates on migrant representations in stories posted on the websites of UK charity organizations. Drawing upon critical discourse analytic and narrative positioning tools, we examine migrant identity navigation in the past and present that, predominantly, leads to the construction of fulfillment identities. We discuss the ways in which these positionings promote an ideal migrant norm that contributes to wider national homogenizing discourses. We view these stories as sites of liquid racism that divide migrants who succeed and are, thus, fulfilled and migrants who are deviant. We interrogate these representations, given that charity organizations are committed to providing social assistance to migrants and refugees, thus aligning with humanitarian and antiracist discourses.

Full textAbstract:
AbstractCooperative positioning approaches enable interconnected agents to share information across the network, thereby improving accuracy, reliability, and safety compared to conventional single-agent localization methods. This chapter presents novel cooperative localization and learning strategies to provide precise positioning in harsh propagating environments as well as reliable environmental mapping for highly-dynamic scenarios. At first, positioning and environmental perception tasks are addressed separately. More specifically, augmentation strategies are proposed to improve positioning accuracy in complex environments by exploiting prior information on the tracking environment. Next, decentralized Federated Learning (FL) policies are developed to obtain accurate environmental sensing at the agents in a privacy-preserving and communication-efficient manner. Then, the localization and environmental perception problems are solved via a unified solution by designing a data-driven cooperative strategy where agents collaborate to enhance their environmental awareness and their positioning capabilities concurrently. Finally, Bayesian FL tools are developed so that the agents are able to incorporate uncertainty in their decisions and consequently provide trustworthy environmental perception. The achieved results show how the proposed techniques can enable accurate, communication-efficient, and trustworthy localization and sensing.

Full textAbstract:
AbstractWhile the construction sector embraces digitalization, new technologies related to it are spreading benefits. The need of creating a 3D model of a building, a digital copy of something existing, is not new. Mediated by the advent of photographic and laser instrumentation, the construction of a digital model has crossed the fields of surveying with increasing accuracy and precision, imposing standards of capturing the existing first and modelling then ever higher. But while the Building Information Modelling allows a virtual representation of the existing asset enriching its geometry with precious and significant information related to its properties, advanced survey has always faced the impossibility to break the surface of the building, surveying what is inside walls, thus excluding what necessary should be contained within a BIM model. Also, BIM models do not consider the real-time component and do not report the real-time behaviour of the building. In this chapter we will investigate several technologies and instruments exploited till now for the surveying and positioning of existing buildings, plants included, and a new toolkit based on AR that, coupled with sensors and visualisation tools developed by BIM4EEB, offers many advantages when surveying the whole building.

Full textAbstract:
The operation of a helicopter with an externally slung load is highly demanding for the flight crew. Without having a direct view on the load, the pilot needs assistance by a crew member for load handling, e.g. load positioning. During Helicopter Hoist Operations (HHO), the hoist operator gives instructions to the pilot and stabilizes the load motion. An automatic load positioning system for HHO is designed with the aim to reduce the workload of the flight crew and to improve the load handling performance. The control system consists of a multi-loop architecture that is designed using multi-objective optimization. The system was designed to achieve best performance in load positioning for the entire cable length range of the rescue hoist. Load positioning performance is a function of the cable length; faster automatic load positioning can be achieved with shorter cable lengths. This paper describes the overall design process covering the tools, control law architecture, optimization, and the validation using DLR's simulator.

The work aims to acquire LiDAR data and checking the scan quality in QC Tools for Sanmihaiu Roman hydro technical arrangement located on the Bega Canal, Timis County, Romania, using mobile scanning technology MMS - Mobile Mapping System, using portable backpack equipment from Swiss manufacturer Leica, the Pegasus Backpack model. The Method of LiDAR Data Collection is a Fused Slam one, where, a Master Station has been located for the purchase of RiNEX data, using some GNSS receiver, the Leica GS 08. The raw data processing was done with the Pegasus Manager program, where the visualization of quality graphs was performed in QC Tools and the data processing was carried out with the Cyclone program, the modelling version (Model), using the SmartPick Point and Virtual Surveyor functions. The scanning accuracy was between 2 and 3 cm. SLAM simultaneous location and mapping technology with IMU (Inertial Measurement Unit) technology of high precision, ensures precise positioning when we have GNSS interruptions. From a technological point of view, MMS is a multi-sensor system consisting mainly of three components: mapping sensors (3D imaging systems), navigation/positioning sensors (IMU/GNSS) and a control unit, which synchronizes and integrates the acquisition of geomatic information, the trajectory of which is calculated.

Aldaba, Rafaelita. Navigating a New Era of Reciprocal Tariffs: Strategic Implications for the Philippines and Selected ASEAN Economies. Philippine Institute for Development Studies, 2025. https://doi.org/10.62986/dp2025.06.
Full textAbstract:
Amid the evolving US-China tariff realignment and the broader restructuring of global value chains, this paper evaluates the vulnerability and strategic positioning of the Philippines alongside four other ASEAN economies—Indonesia, Malaysia, Thailand, and Vietnam. For the ASEAN-5, the key challenge lies in minimizing exposure to import flooding from displaced Chinese goods and potential exclusion from global value chains if competitiveness falters, while also capitalizing on trade and investment diversion opportunities. Using a Tariff Exposure Composite Index (TECI), the assessment reveals that the Philippines and Malaysia fall within the moderate-to-low risk tier, owing to relatively low reciprocal tariff rates and strong exemption coverage—particularly for high-value electronics. Indonesia is classified as moderate risk but is more vulnerable due to limited exemption coverage and a dependence on low-tech, commoditized exports. Meanwhile, Vietnam and Thailand are in the high-risk tier, driven by steep tariffs, significant US export dependence, and only moderate levels of tariff exemption. Absent a coordinated and forward-looking policy response, the Philippines and its ASEAN neighbors risk becoming passive bystanders in an increasingly fragmented trade landscape. However, with strategic alignment of trade and industrial policy, the deployment of robust trade defense tools, and deeper ASEAN collaboration, these economies can reframe the current disruption as a platform to reposition themselves as high-trust, tariff-resilient production hubs in the new global trading order.

Full textAbstract:
Passenger data such as real-time origin-destination (OD) flows and waiting times are central to planning public transportation services and improving visitor experience. This project explored the use of Internet of Things (IoT) Technology to infer transit ridership and waiting time at bus stops. Specifically, this study explored the use of Raspberry Pi computers, which are small and inexpensive sets of hardware, to scan the Wi-Fi networks of passengers’ smartphones. The process was used to infer passenger counts and obtain information on passenger trajectories based on Global Positioning System (GPS) data. The research was conducted as a case study of the Streamline Bus System in Bozeman, Montana. To evaluate the reliability of the data collected with the Raspberry Pi computers, the study conducted technology-based estimation of ridership, OD flows, wait time, and travel time for a comparison with ground truth data (passenger surveys, manual data counts, and bus travel times). This study introduced the use of a wireless Wi-Fi scanning device for transit data collection, called a Smart Station. It combines an innovative set of hardware and software to create a non-intrusive and passive data collection mechanism. Through the field testing and comparison evaluation with ground truth data, the Smart Station produced accurate estimates of ridership, origin-destination characteristics, wait times, and travel times. Ridership data has traditionally been collected through a combination of manual surveys and Automatic Passenger Counter (APC) systems, which can be time-consuming and expensive, with limited capabilities to produce real-time data. The Smart Station shows promise as an accurate and cost-effective alternative. The advantages of using Smart Station over traditional data collection methods include the following: (1) Wireless, automated data collection and retrieval, (2) Real-time observation of passenger behavior, (3) Negligible maintenance after programming and installing the hardware, (4) Low costs of hardware, software, and installation, and (5) Simple and short programming and installation time. If further validated through additional research and development, the device could help transit systems facilitate data collection for route optimization, trip planning tools, and traveler information systems.

Dudoit, Alain. European common data spaces: a structuring initiative that is both necessary and adaptable to Canada. CIRANO, 2023. http://dx.doi.org/10.54932/skhp9567.
Full textAbstract:
Faced with the acceleration of the digital economy, the governance and effective sharing of data have become fundamental issues for public policy at all levels of jurisdictions and in all areas of human activity. This paper reviews the initiatives and challenges associated with data governance, with a particular focus on the European Common Data Spaces (ECDS) and their direct relevance to the Canadian context. It explores the inherent complexity of data governance, which must reconcile sector-specificities with more horizontal governance principles. In doing so, it highlights the importance of strategic and coordinated action to maximize the social and economic benefits of data. The Burgundy Report, published by CIRANO in July 2023, calls for the creation of a common data space in the Great Lakes-St. Lawrence Strategic Trade Corridor by 2030. This proposal builds in particular on three separate policy reports published in 2022 by the National Supply Chain Task Force, the Council of Ministers Responsible for Transportation and Highway Safety (COMT) and the House of Commons Standing Committee on Transportation, Infrastructure and Communities. The findings and recommendations of these reports raise fundamental questions that are central to the critical issues of governance, organizational culture, execution capacity, public and private stakeholder engagement, and data underutilization within the Canadian government machinery strained by years of delay and exacerbated by recent disruptions related to anticipated climate disasters. The creation of a common data space is envisaged as a structuring investment in Canada's essential infrastructure for intermodal transport and the supply chain. This working paper on European Common Data Spaces (ECDS) extends the synthesis and recommendations published last July 2023 by providing an operational analysis of the transformative initiative currently underway within the European Union (EU). This major policy development stems from the 2020 European Data Strategy and seeks to establish twelve common data spaces in strategic sectors, including mobility and transport. The document is divided into three main parts. The first part provides an overview of data-related public policies in Canada and the EU between 2018 and 2023. The second part focuses on the implications and lessons learned from the impact assessment supporting the adoption of data governance legislation by the European institutions. This directive establishes a regulatory framework for the creation of common data spaces in the EU. The third section discusses the current deployment of ECDSs, highlighting key milestones and ongoing processes. The paper highlights notable similarities between the EU and Canada in the identification of data issues and the formulation of public policy objectives. It also highlights differences in optimizing data sharing between jurisdictions and stakeholders. A fundamental difference between these two strategic partners is the absence of an effective and sustained pooling of resources within the Canadian intergovernmental machinery in pursuit of common objectives in the face of major shared challenges such as data accessibility and sharing. This situation is in stark contrast to the EU's groundbreaking deployment of the ECDS in pursuit of identical objectives of positioning itself as a world leader in the data economy. This lack of consideration, let alone joint action, by Canada's intergovernmental machinery to implement a common data strategy in Canada is damaging. To be effective, the Canadian response must be agile, results-oriented, and interoperable across jurisdictions. The rigorous management, responsible use, and organized sharing of data within and between jurisdictions are crucial to addressing the complex challenges and major risks facing Canada. Neither the federal nor provincial governments are currently well positioned to treat data as a shared strategic asset. The resolution of regulatory, legal, and technical obstacles to data exchange between jurisdictions and organizations cannot be achieved without the creation of a common data space. This can only be achieved by combining the necessary tools and infrastructures, and by addressing issues of trust, for example by means of common rules drawn up for this purpose. “The barriers that prevent the establishment of robust health data sharing systems are not technical, but rather fundamentally political and cultural.”
