The mental effort required to perform a simultaneous interpreting task or the cognitive load generated by it has attracted the interest of many a researcher in the field. To date, however, there is little agreement on the most suitable method to measure this phenomenon. In this contribution, I set out to discuss four of the most common methods of measuring cognitive load and the way in which they have been applied in interpreting research, providing examples for each and highlighting their respective advantages and disadvantages. The main focus of the contribution will be on pupillometry, a psycho-physiological method I deem to be among the most promising approaches to objectively measure cognitive load during simultaneous interpreting in real time.

The aim of this paper is to present how the online interpreter training was conducted during the Covid-19 pandemic at the Institute of Translation Studies (Charles University, Faculty of Arts) in the last three semesters (during the academic years 2019/2020 and 2020/2021). In this paper, we try to describe the advantages and disadvantages of distance interpreter training (DIT) both from the point of view of teachers and students, we explain how the online lectures of simultaneous and consecutive interpreting were organized and we also discuss the differences of the platforms that we used. The students were administered a questionnaire to explore the learners’ attitudes and feelings regarding remote interpreting in interpreter training with a view to identifying the possibilities and limits of this type of learning experience compared with conventional forms of instruction. The latter part of the paper will comment on the most interesting student responses.

Full textAbstract:
SummaryClinicians are increasingly faced with the problem of interpreting subtle, early cognitive symptoms. Enhanced awareness of Alzheimer's disease (AD) and available treatments has led to a growing demand for early assessment. Although it is known that a proportion of individuals with mild cognitive impairment will progress to dementia in following years, our ability to identify these individuals and predict individual cognitive trajectories is limited. The emergence of disease-modifying treatments would make these problems more acute. In this review, the potential role of magnetic resonance imaging (MRI) in aiding the clinician in early diagnosis of AD will be considered. The changes in grey matter structure that accompany ‘normal’ ageing will be described briefly, before moving on to studies that have attempted to distinguish the onset of disease from this background of structural change. Volumetric methods range from measurements of single key structures, such as the hippocampus, to methods based on computational neuroanatomy, which evaluate subtle structural alterations across the whole brain simultaneously. Computational methods are rapidly evolving and already perform as well as radiologists in distinguishing AD from normal ageing at an individual level. This article aims to provide a practical knowledge of how and why these methods work, point out the main advantages and disadvantages and sketch out outstanding issues and possible future directions.

Full textAbstract:
This study is a plea for introducing ‘pen and paper’ as traditional tools in consecutive interpreting. The study is built on the examination of the traditional note-taking tools and their use in interpreting. Its purpose is to discuss their potentialities, as well as to determine to what extent the traditional tools and methods of note-taking are still valuable and compatible with other new ones. The discussion is done through the descriptive method of the process and techniques of consecutive interpreting. The development of these themes aims to point out the benefits to obtain by the use of traditional tools. The study tries, also, to reveal the advantages and disadvantages of the use of these traditional tools compared to the new technological devices used in consecutive interpreting. The results confirm the effectiveness of these traditional pen and paper tools, as they still in work that enables the consecutive interpreter to accomplish his/ her work. The conclusion and findings suggest some solutions such as the use of traditional tools threatened by e-generation devices and digital technology. It, also, mitigates the attacks on these formal tools. It provides a method for the fulfillment of the objectives of consecutive interpreting regardless of the tools used by the interpreter.

Full textAbstract:
This paper uses eye-tracking research to examine the cognitive load and translation accuracy of simultaneous interpretering with and without technology-assisted in the direction of Chinese-to-English translation and to explore the moderating role of simultaneous interpreting ability. It was found that the new type of simultaneous interpreting assisted by speech recognition technology and machine translation technology can significantly reduce the cognitive load of student interpreters and improve the accuracy of translation. However, the advantages of technology-assisted simultaneous interpreting are not significant enough for professional interpreters compared with student interpreters. This paper explains the results of the study from the perspectives of memory pressure, bilingual switching pressure, and the “ceiling effect”.

Full textAbstract:
The development of telecommunication technologies has created a demand on educational institutions to offer interpreting programs by distance mode. This demand arises from educational needs, financial considerations, and market developments. Although several educational institutions and interpreting service providers have attempted to train interpreters by remote delivery, a commonly expressed concern is whether distance programs can be as effective as on-campus ones. This paper presents an analysis of fundamental features of interpreting and on-campus training, as well as issues associated with the distance mode of interpreter training programs. Three telecommunication technologies that could be used for teaching interpreting — teleconferencing by telephone, videoconferencing through local area networks (LANs) and videoconferencing through the Internet — are analyzed with regard to feasibility, reliability and affordability. The results show that each of these has its advantages and disadvantages. The challenge facing educators is to overcome the technical constraints, maximize the advantages and the potential of current technologies, and adapt pedagogies to best fit the new technologies so as to achieve results comparable to those of on-campus teaching.

The next important step in the development of Interpreting Studies appears to be its methodological consolidation, which can be achieved by drawing on the findings of systems theory. Systems theory makes it possible to grasp the complexity of interpreting and to master the resulting interdisciplinary methodological challenges. The example given in this article of the first system-dynamic model of simultaneous interpreting demonstrates the advantages of such an approach and explains that it is time for a systemic turn.

Full textAbstract:
This chapter is dedicated to calorimeter techniques that have been developed since the first edition of this monograph was published (2000). The Dual Readout Method (DREAM) aims to combine the advantages of compensation (linearity, excellent hadron resolution, Gaussian line shape) with a certain amount of design flexibility. This method, based on simultaneous detection of scintillation and Cherenkov light produyced in the shower development, eliminates some of the disadvantages of compensating devices, and in particular the dependence on efficient neutron detection of the latter. The Particle Flow Analysis method aims to combine the information provided by a good tracking system with that provided by a fine-grained calorimeter system to obtain excellent performance for the detection of jets. The results achieved with both methods, and the challenges faced in practice, are described in detail.

Full textAbstract:
Abstract Observation and introspection can be used as qualitative, cognitive ethnographic research methods. Qualitative field observation allows researchers to study translators, interpreters and other relevant actors in situ. Introspective diaries facilitate a deeper understanding of the cognitive processes of note takers. Both are rooted in ethnographic research principles, which is reflected in the data collection techniques, observational modes and ethical considerations described in this chapter. They support the understanding of activities in their social and material environments and histories. This chapter introduces these two research methods and examines ethical issues, conceptual aspects and implementations of observational and diary research. It discusses advantages and disadvantages of the two methods, considers their relevance for translation and interpreting studies research and provides practical recommendations for research projects.

Full textAbstract:
AbstractEnsuring everyone has access to health care regardless of demographic, geographic and social economic status is a key component of universal health coverage. In sub-Saharan Africa, where populations are often sparsely distributed and services scarcely available, reducing distances or travel time to facilities is key in ensuring access to health care. This chapter traces the key concepts in measuring spatial accessibility by reviewing six methods—Provider-to-population ratio, Euclidean distance, gravity models, kernel density, network analysis and cost distance analysis—that can be used to model spatial accessibility. The advantages and disadvantages of using each of these models are also laid out, with the aim of choosing a model that can be used to capture spatial access. Using an example from Uganda, a cost distance analysis is used to model travel time to the nearest primary health care facility. The model adjusts for differences in land use, weather patterns and elevation while also excluding barriers such as water bodies and protected areas in the analysis. Results show that the proportion of population within 1-h travel times for the 13 regions in the country varies from 64.6% to 96.7% in the dry period and from 61.1% to 96.3% in the wet period. The model proposed can thus be used to highlight disparities in spatial accessibility, but as we demonstrate, care needs to be taken in accurate assembly of data and interpreting results in the context of the limitations.

Full textAbstract:
AbstractThis chapter discusses how the fundamental values of energy democracy and energy justice and the principles of good governance can play a role in developing a more consistent approach towards the regulation of the energy sector and, more in particular, in dealing with the challenges of regulating the heat transition in the Netherlands in a just way. Energy justice and energy democracy are energy specific concepts that are gaining influence when interpreting and applying the principles of good governance in the energy sector. Both concepts are based on the awareness that the energy transition is a matter for all citizens of the European Union and should not be ignored by policymakers and independent regulators. The heat transition in the Netherlands significantly impacts the position of consumers, prosumers and vulnerable customers, as an ever-larger group of consumers will be disconnected from the gas grid and will be connected to heat networks. Energy democracy and energy justice and the principles of good governance are important values that should guide policy-makers in making choices that affect consumer participation and the protection of vulnerable customers in the heat transition. It is elaborated how energy democracy and energy justice and the principles of good governance indeed can provide a useful framework within which advantages and disadvantages can be weighed of regulatory choices to be made when modernising the regulation of the heat market in a just way. In particular, there remains a lot to gain in terms of flexible regulation and supervision as well as the facilitation of consumer/prosumer participation in the Netherlands. Because it is likely that most heat consumers will remain locked in for a relatively long time in natural monopolies facilitated by older generation heat networks and the lack of alternative heating, substantive consumer-participation could yield positive results regarding community engagement in heat network management and heat supply.

Full textAbstract:
Osteoarthrosis is the most common chronic joint condition, the aetiology of which is still not completely clear. Initial phases of disease are treated conservatively applying physical rehabilitation procedures and medications. Advanced stages need surgical treatment with numerous procedures, depending on the joint affected. Joint arthroplasties are procedure of choice, especially for big joints of the extremities. As osteoarthrosis occurs bilaterally very frequently, there are a growing number of patients in need for operation of both joints. Those procedures can be performed under single anaesthesia or staged procedure, with delay between two surgeries. There are many advantages and disadvantages of both approaches cited by different authors. There is consensus of authors in available articles regarding benefits of single-stage procedure: lower cost, shorter hospital stay, single rehabilitation period and better functional results. Authors disagree about safety of a single-stage bilateral procedure as well as incidence of complications and criteria for selection of patients for safe performing of simultaneous procedure.

Democratic systems ensure the constitutional transfer of power through the vital process of conducting smooth, timely and clean elections. For many years, the idea of holding simultaneous elections in both federal and unitary democratic systems has been a source of both academic and political debate. Proponents of this notion say that it will save time, money, and resources, while opponents argue that it will erode democratic and federalist values. However, this essay delves into the complicated issues of holding simultaneous elections in a country as varied as India. It investigates the implementation limits and complexity, constitutional consequences, logistical issues, uneven political cycles, and the potential impact on regional parties and federalism. The paper concludes by proposing potential solutions and an analysis of the advantages and disadvantages of such a system. The study incorporates existing literature analysis, official reports, and expert comments to create a comprehensive picture.

Transparency and interpretability of algorithms are essential factors required while developing and implementing AI-based medical imaging systems. Algorithm transparency ability lies in understanding and interpreting how an AI algorithm arrives at its decisions or predictions. This is the main challenge in implementing AI-based medical imaging techniques. Methods like explainable AI (XAI) are utilized to show how the algorithm makes decisions and points out important parts of the input data. These methods include feature visualization, attention mechanisms, artificial neural networks, and conceptNet. In our work, we perform extensive algorithmic testing and evaluation on various datasets, including external testing using real-world clinical data. The algorithm's advantages and disadvantages require openness in reporting evaluation results

Full textAbstract:
Radio Frequency Identification (RFID) is a challenging wireless technology with a great potential for supporting supply and inventory management. In this chapter the authors consider a particular application in which a group of tagged items are scanned to generate a record of simultaneous presence called a grouping-proof. Grouping-proofs can be used, for instance, to guarantee that drugs are shipped (or dispensed) accompanied by their corresponding information leaflets, to couple the user’s electronic passport with his/her bags, to recognize the presence of groups of individuals and/or equipment and more generally to support the security of supply and inventory systems. Although it is straightforward to design solutions when the verifier is online since it is sufficient for individual tags to authenticate themselves to the verifier, interesting security engineering challenges arise when the trusted server (or verifier) is not online during the scan activity. So, the field of grouping-proofs is very active, and many works have been published so far. This chapter details the setting for RFID grouping-proofs and discuss the threat model for such applications. The authors analyze some of the grouping-proofs proposed in the literature describing their advantages and disadvantages. Then, general guidelines for designing secure grouping-proofs are proposed. Finally, some examples of grouping-proofs that are provably secure in a strong security framework are presented.

In Innovative Geotechnologies for Energy Transition. Society for Underwater Technology, 2023. http://dx.doi.org/10.3723/nkow2821.
Full textAbstract:
The seismic cone penetration test (SCPT) is an essential tool for establishing in-situ shear wave velocity (vs ) and hence Small Strain Shear Stiffness (Gmax ). The technique has received intense attention recently as it is considered the most reliable in-situ tool available to deliver Gmax profiles. These profiles are used to calibrate results of advanced laboratory testing and as direct input for numerical modelling of offshore windfarm foundations. However, although SCPT has been performed routinely on land for many years, the complexities of performing this kind of testing with a seismic source located on the seabed presents ongoing challenges for the industry. Additionally, there remains disagreement amongst the engineering and academic community over the most appropriate data interpretation methods. The lack of standardisation between contractors in equipment capability and arrangements, data deliverables and methods for interpretation can lead to difficulties for practicing engineers in establishing the reliability of the generated data sets. The authors provide a critical review of the acquisition methods utilised and how these affect the quality, volume and validity of the data. An appraisal of the advantages and disadvantages of true interval straight ray path and pseudo interval true ray path processing methodologies is presented along with alternative recommendations for developing design vs profiles.

Full textAbstract:
Abstract This paper presents a comprehensive study of the various stimulation fluids implemented worldwide in terms of their effectiveness, the advantages and disadvantages of the fluids in comparative analyses. Furthermore, the study highlighted the challenges related to the utilization of these fluids and their further development. The research employed a multi-faceted approach of collecting, analyzing, and interpreting data from multiple sources. This included an extensive review of available literature and records, lab testing and a close examination of stimulation fluid samples. To further gain an understanding of the fluids’ efficacy, field testing was conducted in the laboratory setting and onsite in the field. Various data were gathered and analyzed for a comprehensive assessment of the different stimulation fluids in more than thousands of treatments, using artificial intelligence tools. Finally, these results were analyzed to come up with the optimal stimulation fluids for use in particular geological conditions. The most common fluid systems are gelled HCl acid, emulsified acid systems, different variations of viscoelastic surfactant-based systems, nitrogen and carbon dioxide-based foamed fluids, crosslinked fluid systems, relative permeability modifiers, and others. Additionally, the study found that there were both advantages and disadvantages associated with each fluid in terms of efficiency, application features, and performance. The study categorizes different fluid systems based on formation type, temperature, depth, treatment type, and other factors. As an example, the carbon dioxide-foamed acid-based fluid system is found to be an effective fluid system to stimulate tight HPHT-depleted formations improving stimulation fluid recovery by up to 40% and increasing initial productivity by 17%. Furthermore, proper water management strategies and environmental considerations must be taken into consideration to ensure further successful utilization. The effectiveness of the various stimulation fluids varies greatly and therefore careful consideration must be taken before selecting the optimal fluid using artificial intelligence tools. The research outcome provides a comprehensive decision tree and categorization workflow for fluid selection, addressing various well and geological challenges. Petroleum engineers would find this article valuable when selecting the appropriate fluid for treatment.

Full textAbstract:
Resonance ionization mass spectrometry (RIMS) is being developed to measure 230/232Th ratios (~5:105), which are used in U-series disequilibrium dating of geological samples of the last 400,000 years. We will discuss the precision and accuracy of the ratio measurements when resonant excitation with a broad-band dye laser and a narrow-band frequency-doubled Ti:sapphire laser is used. The dye laser is evaluated with and without optogalvanic frequency locking onto a Th transition to provide better reproducibility. The relative advantages and disadvantages of the two excitation sources will be summarized, including 1) narrowband excitation yielding greater isotope selectivity versus 2) broad-band laser excitation providing higher sensitivity (simultaneous excitation of all relevant isotopes and all atoms within the Doppler profile).

Full textAbstract:
The paper presents two different optimization methods for the cost-effective design of energy conversion systems. Starting point of the optimization is a complex superstructure that allows several alternative design specifications for a combined-cycle-based cogeneration plant to be studied. Depending on the user specified demands for electricity and process steam, the optimization algorithm performs a simultaneous structural and process variable optimization of the design, to minimize the levelized total costs of the plant products. Mathematical programming and specialized genetic algorithms are used as optimization algorithms. These do not only differ largely in their optimization approach but also have different requirements for the modeling of the superstructure. Several optimization cases are presented to examine the applicability of both algorithms on the present optimization problem. A concluding comparison reveals the advantages and disadvantages of each optimization method.

Full textAbstract:
In recent years, there has been an increased emphasis worldwide on the quality of the environment, especially with an orientation towards the application of renewable energy sources. In addition, we are increasingly encountering experimentation aimed at obtaining new green energy sources. One of such sources is biomass. Biomass has been used since the middle ages as a source of heat and light energy. Today, however, we have technologies that allow us to obtain not only heat but also electricity from biomass, or to convert biomass into materials with high energy density and purity. The energy thus transformed can then be used, for example, as a propellant. At the same time, this valuable source of clean energy can be easily transported to the place of consumption. By applying biomass as a source of green energy, we can make a significant contribution to relieving the environment from harmful effects. In recent years, an increased interest in energy obtained from biomass can be observed in Slovakia. Its technical potential is the greatest among other renewable energy sources, and its non-use would essentially be wastage. Therefore, the aim of the paper was to describe two possibilities of transformation of biomass in the form of its energy recovery into the type of energy used for the production of mechanical, thermal and electrical energy. At the same time, in addition to obtaining a suitable form of energy from biomass, another environmental benefit was sought in the form of soil decontamination. In this regard, there is an energetically important crop, which is known under the Latin name Amaranthus caudatus. It is an energy crop that can be grown on slightly contaminated soil with some restrictions. Two methods of energy recovery of this crop were compared. In the first case it was its compaction into briquettes, in the second case it was a process of anaerobic fermentation with subsequent production of biogas. Based on the performed analysis, it was found that these are almost equivalent energy sources. Although both methods of transformation and energy recovery of the green part of Amaranthus caudatus crops have a number of advantages and disadvantages, it can be clearly stated that the positives significantly outweigh the negatives. Therefore, it is recommended to apply this crop as a valuable source of energy for use in real conditions.

Full textAbstract:
A new thermodynamic cycle has been developed for the simultaneous production of power and cooling from low temperature heat sources. The proposed cycle combines the Rankine and absorption refrigeration cycles, providing power and cooling as useful outputs. Initial studies were performed with an ammonia-water mixture as the working fluid in the cycle. This work extends the application of the cycle to working fluids consisting of organic fluid mixtures. Organic working fluids have been used successfully in geothermal power plants, as working fluids in Rankine cycles. An advantage of using organic working fluids is that the industry has experience with building turbines for these fluids. A commercially available optimization program has been used to maximize the thermodynamic performance of the cycle. The advantages and disadvantages of using organic fluid mixtures as opposed to an ammonia-water mixture are discussed. It is found that thermodynamic efficiencies achievable with organic fluid mixtures, under optimum conditions, are lower than those obtained with ammonia-water mixtures. Further, the refrigeration temperatures achievable using organic fluid mixtures are higher than those using ammonia-water mixtures.

This work focuses on incorporating component shape design into a vehicle configuration design or layout process. A concurrent design process consisting of performing layout design and simultaneous shape morphing of some select components is adopted to replace the traditional sequential design approach. The objective is to improve design efficiency and reduce design cost. Two important issues in the packing optimization with shape morphing problem are identified and studied: the morphing and the optimization. A parameterization-based morphing method and a mesh-based morphing method are implemented, and their advantages and disadvantages are discussed. To efficiently solve this complex problem, it is proposed to decompose it into a bi-level formulation: system level and component level. At the system level, the given functional objectives of the layout design problem are optimized with respect to component positions and orientations. At the component level, the shape of select components is morphed to minimize the overlap with other objects and the enclosure. By iterating between these two levels, the original problem is solved. This bi-level approach is intended to overcome the complexity of performing the placement simultaneously with the shape morphing.

Full textAbstract:
Material characterization by Near Infrared Hyperspectral Imaging (NIR HSI) is based on specific absorption features of different minerals. These absorption features are caused by the movement of molecular bondings of NIR active minerals on the material surface. Therefore, pollutions, such as dust and water, may influence the measurement outcome. An insufficient spatial resolution of the measurement can additionally falsify the hyperspectral image, because of mixed spectra effects at grain boundaries caused by the simultaneous collection of two or more spectra from unequal minerals. In order to compare NIR HSI to conventional analytical methods the above mentioned characteristics have to be investigated to reveal the potential of NIR HSI. The present paper describes investigation conducted on copper porphyry ore derived from the Kajaran copper mine, Armenia. During an extensive feasibility study rock samples are characterized by different measurement techniques. Two major analysis technologies are used for characterization including Mineral Liberation Analysis (MLA) and NIR HSI by using the Hyperspectral Imager SisuCHEMA (SPECIM) and Spotlight 400 FTIR Imaging System from Perkin Elmer. On basis of test-results derived from the feasibility study advantages and disadvantages of NIR HSI, in comparison to conventional measurement techniques in the minerals industry are discussed.

Full textAbstract:
Cracking and bulging in welded and internally lined pressure vessels that work in thermal-mechanical cycling service have been well known problems in the petrochemical, power and nuclear industries. In spite of this problem has been studied during the last fifty years, published literature and industry surveys show that similar problems still occur nowadays. Typical examples of this problem are the coke drums in the delayed coking units refinery process. Delayed coking units are among the refinery units that have higher economical yields. To shut down these units represents a high negative economical impact in refinery operations. Also, the maintenance costs associated with repairs are commonly very high. Cracking and bulging occurrences in the coke drums, most often at the weld areas, characterize the history of the operation of delayed coking units. To anticipate through wall cracking in these coke drums, AUT (automatic ultrasonic testing); Dual TOFD (time of flight diffraction) and the Phased Array technique simultaneous inspection system was selected among other inspection techniques as a condition monitoring tool during an unit turnaround. The inspection methodology in combination with fracture mechanics was used to classify discontinuities as acceptable and non-acceptable. This indicated approach helped to optimize the workscope during the turnaround and establish guidelines for inspection and repair of the delayed coker unit. This work presents the different steps followed during the inspection and fitness for service evaluation. Also, this study shows advantages and disadvantages of the AUT-Phased Array technique.

Full textAbstract:
This work presents manufacturing and testing of active composite panels (ACPs) with embedded piezoelectric sensors and actuators. The composite material employed here is a plain weave carbon/epoxy prepreg fabric with about 0.3 mm ply thickness. A cross-ply type stacking sequence is employed for the ACPs. The piezoelectric flexible patches employed here are Active Fiber Composites with 0.33 mm thickness. Composite cut-out layers are used to fill the space around the embedded piezo patches to minimize the problems associated with ply drops in composites. The piezoelectric patches were embedded inside the composite laminate. High-temperature wires were soldered to the piezo leads, insulated from the carbon substructure by high-temperature materials, and were taken out of the composite laminates employing both cut-hole and embedding techniques. The laminated ACPs were co-cured inside an autoclave employing the cure cycle recommended by the composite material supplier. The Curie temperature of the embedded piezo patches should be well above the curing temperature of the composite materials as was the case here. The manufactured ACPs were trimmed and then tested for their functionality. Vibration suppression as well as simultaneous vibration suppression and precision positioning tests, using Hybrid Adaptive Control techniques were successfully conducted on the manufactured ACP beams and plates and their functionality were demonstrated. The advantages and disadvantages of ACPs manufactured by taking the wires out employing cut-holes and embedding techniques, in terms of manufacturing and performance, are presented.
