İngilizce’nin Yabancı Dil Olarak Öğretiminde Ünite Tasarım Şablonu Olarak UbD’nin Kullanımı: Yararları ve Zorlukları

This study aims to explore English language teachers’ and English department heads’ perspectives on the benefits and challenges of designing and delivering units using Understanding by Design (UbD) framework to teach English as a Foreign Language (EFL). UbD is a unit and curriculum design framework which aims for student understanding and its transfer into real life context through three stages: identifying the desired results, determining the assessment evidence, and planning learning activities. Data was collected through open-ended questionnaires from 39 English language teachers and five department heads, and semi-structured focus group interviews with seven teachers. The content and thematic analysis of the qualitative data revealed that the teachers who implemented UbD within the context of their school perceived it as a design process with benefits on students’ academic achievement and English language skills through its focus on the development of understandings and transfer. The findings also uncovered perceived challenges caused by institutional, instructional, teacher related and learner related factors. Teachers also found UbD implementations challenging due to the characteristics of online education during the global pandemic. These findings suggest that although UbD is not commonly used at schools in the Turkish EFL context, it can be offered as an alternative unit design practice if teachers’ professional knowledge of its underlying principles is increased with regular in-service trainings on its proper implementation.

The Amount of Circulation when Forming the Aerodynamic Appearance of a Main Aircraft

The work proposed by the authors describes the mechanism for the formation of induced drag for a wing of finite span, as well as a possible option for taking into account the circulation value as a control parameter in the process of preliminary design of a mainline aircraft wing equipped with additional aerodynamic surfaces (wing tips, winglets).Providing the least frictional resistance is achieved by the smoothness of the wing surface in combination with laminar profiles (with the greatest length of the laminar section of the boundary layer), when critical values of the M number are reached, supersonic zones appear on the wing, therefore it is necessary to delay the occurrence of the wave crisis as much as possible - apply the sliding effect for the swept wing of the final scope. A reduction in inductive drag can be achieved by using a high aspect ratio wing or various types of wing tips, which make it possible to control the amount of circulation and localize the process of pressure flow near the end part of a wing of finite span by increasing the effective span. The study of the flow around an aerodynamic model of a mainline aircraft formed the basis of the conceptual model and mathematical support that implements the methodology for selecting the composition of rational design parameters. The identified experimental data and functional dependencies made it possible to form a vector of parameters for a formal aerodynamic model, connecting the geometry of the aircraft model (shape) and its aerodynamic characteristics through dimensionless coefficients for various operating characteristics. Analysis of the results and subsequent processing in order to synthesize a design solution on a validation basis involves the use of a formalized multi-parameter approach, i.e. machine (computer) processing is required. The implementation of a multi-parameter approach in application software in the C++ programming language will allow us to explore and establish connections between parameters and obtain a new version of the design alternative using a smaller amount of data.

Sailing Performance of Wind-Powered Cargo Vessel in Unsteady Conditions

The need to reduce green-house gas emissions from shipping has reborn the interest in wind propulsion for commercial cargo vessels. This places new requirements on the tools used in ship design, as well as the methods usually applied in sailing yacht design. A range of design tools are used by designers at various stages in the design of wind-assisted ships and for different purposes. One important tool is the steady-state velocity prediction program (VPP) which is typically used to predict the speed of the vessel when sailing in a range of wind directions and wind speeds. Steady-state VPPs can be very efficient and fast and may be used to rapidly assess a large number of design alternatives. However, steady-state VPPs are not able to consider dynamic effects such as unsteady wave forces on the hull which may require the rudder to be active to control the heading and course of the vessel. This, in turn, leads to different mean forces than those predicted by a static VPP and therefore the sailing performance may be reduced compared to the predictions of a static VPP. Another effect of the ship’s motions in a seaway is that the angles of attack of the sails fluctuate, which can lead to different optimum sheeting angles and possibly a loss of performance. This study uses an unsteady 3D fully nonlinear potential flow hydrodynamic model coupled with an efficient lifting-line aerodynamic model to investigate the differences in sailing performance of a vessel sailing in steady conditions to the performance when sailing in a seaway and gusty wind based on a spatio-temporal wind model. The analysis shows clearly that the unsteady wind model affects the predicted performance. This is especially the case when sailing close-hauled and on a beam reach, where large changes in the local sail angles of attack can be observed.

Time series classification with their image representation

The study is concerned with the problem of classification of multivariate time series using convolutional neural networks (CNNs). As CNNs regard inputs in the form of images, an original image-like format of temporal data is proposed. Along this line, several design alternatives are studied by forming images with the two corresponding coordinates built by the original temporal data and their differences and second differences. An overall design process is presented with a focus on investigating time series-image transformations. Experimental studies involving publicly available data sets are reported, along with a slew of comparative analyses.

FLEXURE BASED LINEAR GUIDE WITH MICROMETRIC PRECISION

Linear guides represent the backbone of the manufacturing machines. Their properties have a direct impact on the machine characteristics and so they are given a special attention. Among these, linear guides with micrometric precision are a special case, which normally requires expensive manufacturing processes and complex assembly procedures. This work proposes an alternative design, based on the compliance of materials, which implies a significantly simpler production process, lower overall production costs and a much smaller manufacturing time. The resulted mechanical system will exhibit no backlash, does not require maintenance, has a very long life and is suitable to work in particle contaminated environments.

ПРО ОДНУ З МОЖЛИВИХ ТЕХНОЛОГІЙ ТА ВАРІАНТУ ЇЇ РЕАЛІЗАЦІЇ НА ВИМОГУ ПОЛОЖЕНЬ ДСТУ-Н Б В.1.2-18:2016

In the context of modern development in the construction industry and engineering design, the utilization of Building Information Modeling (BIM) has acquired strategic significance for the technical inspection of buildings. This article examines the importance of BIM as a tool aimed at obtaining comprehensive and detailed information about the construction, condition, and functionality of buildings. The primary objective of employing BIM in the context of technical inspections lies in the ability to create digital models that integrate diverse data related to the constructive and engineering characteristics of buildings. This ensures the standardization of information and simplifies analytical processes directed towards making well-founded decisions. The process of modeling an analytical model within the BIM system requires the integration of calculations with model parameters to account for the behavior of constructions under various load conditions and different design alternatives. The application of analytical analysis methods in the digital environment allows for more precise and reliable results, facilitating the identification of potential issues and optimizing design decisions.
 The paper presents an analysis of the experience in using preprocessors in creating computational models within the BIM system. Special attention is given to the role of the Structural Information Model (SIM) in the life cycle of the BIM model. The rules and methods of SIM development in the information modeling system are discussed, along with the unique features in the development of an analytical model within the SIM system. The study elaborates on the advantages of utilizing SIM during the technical inspection of buildings and provides specific examples for addressing typical issues in the construction phase. Emphasis is placed on potential outcomes and functionality achievable through the use of the SIM model in addressing tasks related to the technical inspection of buildings, contributing to the enhancement of efficiency and accuracy in the analysis of structural conditions.

Fiber reinforced additive manufacturing: structurally motivated print orientation and sequential topology optimization of anisotropic material

PurposeFiber reinforced additive manufacturing (FRAM) is an emerging technology that combines additive manufacturing and composite materials. As a result, design freedom offered by the manufacturing process can be leveraged in design optimization. The purpose of the study is to propose a novel method that improves structural performance by optimizing 3D print orientation of FRAM components.Design/methodology/approachThis work proposes a two-part design optimization method that optimizes 3D global print orientation and topology of a component to improve a structural objective function. The method considers two classes of design variables: (1) print orientation design variables and (2) density-based topology design variables. Print orientation design variables determine a unique 3D print orientation to influence anisotropic material properties. Topology optimization determines an optimal distribution of material within the optimized print orientation.FindingsTwo academic examples are used to demonstrate basic behavior of the method in tension and shear. Print orientation and sequential topology optimization improve structural compliance by 90% and 58%, respectively. An industry-level example, an aerospace component, is optimized. The proposed method is used to achieve an 11% and 15% reduction of structural compliance compared to alternative FRAM designs. In addition, compliance is reduced by 43% compared to an equal-mass aluminum design.Originality/valueCurrent research surrounding FRAM focuses on the manufacturing process and neglects opportunities to leverage design freedom provided by FRAM. Previous FRAM optimization methods only optimize fiber orientation within a 2D plane and do not establish an optimized 3D print orientation, neglecting exploration of the entire orientation design space.

Optimal Design of a Surface Permanent Magnet Machine for Electric Power Steering Systems in Electric Vehicle Applications Using a Gaussian Process-Based Approach

The efficient design optimization of electric machines for electric power steering (EPS) applications poses challenges in meeting demanding performance criteria, including high power density, efficiency, and low vibration. Traditional optimization approaches often fail to find a global solution or suffer from excessive computation time. In response to the limitations of traditional approaches, this paper introduces a novel methodology by incorporating a Gaussian process-based adaptive sampling technique into a surrogate-assisted optimization process using a metaheuristic algorithm. Validation on a 72-slot/8-pole interior permanent magnet (IPM) machine demonstrates the superiority of the proposed approach, showcasing improved exploitation–exploration balance, faster convergence, and enhanced repeatability compared to conventional optimization methods. The proposed design process is then applied to two surface PM (SPM) machine configurations with 9-slot/6-pole and 12-slot/10-pole combinations for EPS applications. The results indicate that the 12-slot/10-pole SPM design surpasses the alternative design in torque density, efficiency, cogging torque, torque ripple, and manufacturability.

Parameters and Operation Modes of the Cutting and Chopping Apparatus

ntroduction. To improve the efficiency of harvesting crops, it is necessary to improve the existing tools of mowers and headers of combine harvesters that will ensure their versatility and multifunctionality. The increased power availability per the industry in the current economic and political conditions can be achieved by applying the principles of resource conservation and using alternative designs of reaper and headers. The existing cutting units of these agricultural machines do not provide simultaneous cutting, harvesting and chopping of corn stalks, sunflower stalks, reed steams and branches for the purpose of futher incorporation into the soil or collection of plant mass to use in liverstock. Therefore, substantiating the design and technological scheme and determinating the parameters and modes for the universal cutting and chopping apparatus is relevant. Aim of the Article. The aim of the work is to increase the efficiency of cutting and chopping plants by substantiating the structural and functional scheme of the unit and the ration parameters and operating modes of the cutting unit. Materials and Methods. The physics of the kinematic mode indicator is substantiated in terms of the probability-based approach. The research was carried out in the laboratory of the Department of Operation and Technical Service and in the training park of Kuban State Agrarian University. Results. There is substantiated the structural and functional scheme of the chopper unit with a cutterbar of cutting and chopping type. The physics of the kinematic mode index characterizing the intensity of interaction of a certain number of knives with plants on the root and stems distributed over the area with different density, is substantiated for the accepted conditions of the unit operation, in terms of probabilistic approach to the interaction of knives with stems in the form of plants on the root. Discussion and Conclusion. The obtained data are necessary for designing universal machines of a new type, providing not only cutting, but also collecting of cut stems, chopping and possible collecting of the chopped crop or spreading chopped crop on the field. Depending on the rotational speed of the auger tool, an indicator of the kinematic mode, the power varies from 4.99 kW to 11.02 kW, productivity from 0.5 kg/s to 1.22 kg/s, and energy consumption from 11.02 to 4.99 kW-s/kg.

Multi-Objective Finned-Tube Heat Exchanger Optimization Using a Genetic Algorithm

Heat exchangers are a significant component in many industries, particularly in energy conversion systems. The design of heat exchangers itself is a complex process because it involves experience-based decisions, numerous variables and parameters, and some of them are competing with each other. Genetic Algorithms (GAs) are one of the first evolutionary algorithms which remains one of the most extensively used non-linear optimization methods today. This study explores the implementation of Non-Dominated Sorting Genetic Algorithm II (NSGA-II) for thermal design and optimization of a finned-tube heat exchanger. The chosen objective functions were minimizing the heat exchanger volume and minimizing the air side pressure drop. The decision variables for the design were tube outer diameter, number of tube rows, fin pitch, unit height, and unit width. The calculated parameters and estimated cost of both preliminary design and optimized design were also compared. The optimized design offered a bigger alternative design while meeting all the constraints according to standards and industrial needs. The optimization reduced annualized operational and maintenance costs by 228% and lowered air pressure drop by 413% with bigger heat exchanger volume of 12% compared to the preliminary design.

Thermal and structural analysis of the European water-cooled lithium lead breeding blanket concept in the L-H mode transition

The design of a breeding blanket system (BB) which reliably fulfils the prescribed requirements is pivotal for the construction of the EU DEMO fusion reactor. For this reason, the BB conceptual design activities require a tighter interaction with plasma physics modelling, so to employ relevant boundary conditions to compare, and then down-select, the BB design alternatives. The preliminary thermo-mechanical study herein reported highlights the importance to assess in deep the BB performance during plasma operational transients. In particular, analyses of the BB thermal and mechanical transients during plasma ramp-up have been carried out, with focus on the L-H transition. Attention has been paid to the Water-Cooled Lithium Lead (WCLL) BB concept, one of the two driver blanket candidates for the EU DEMO project. Adopting DEMO-relevant plasma configurations, the fusion power and the radiative power time evolutions during the plasma ramp-up phase have been modelled under different assumptions using the code ASTRA. The obtained power transients have been used to calculate the time-dependent nuclear power density and radiative heat flux the WCLL BB is subjected to, in order to perform the corresponding transient thermal analysis. Then, the structural analysis has been carried out in order to verify the fulfilment of the RCC-MRx structural design criteria in the most critical time steps. The performed thermo-mechanical analysis has been carried out adopting the Abaqus FEM code. Results obtained are presented and critically discussed, highlighting their importance for the EU DEMO integrated design.

Reduction of renal activity retention of radiolabeled albumin binding domain‑derived affinity proteins using a non‑residualizing label strategy compared with a cleavable glycine‑leucine‑glycine‑lysine‑linker.

The feasibility of targeted imaging and therapy using radiolabeled albumin‑binding domain‑derived affinity proteins (ADAPTs) has been demonstrated. However, high renal uptake of radioactivity limits the maximum tolerated dose. Successful reduction of renal retention of radiolabeled Fab fragments has been demonstrated by incorporating a cleavable linker between the targeting agent and the radiometal chelator. The present study investigated if the introduction of a glycine‑leucine‑glycine‑lysine (GLGK)‑linker would reduce the kidney uptake of radiolabeled ADAPT6 and also compared it with the non‑residualizing [125I]I‑[(4‑hydroxyphenyl)ethyl]maleimide ([125I]I‑HPEM) labeling strategy. GLGK was site‑specifically coupled to human epidermal growth factor receptor 2 (HER2)‑targeting ADAPT6. Conjugates without the cleavable linker were used as controls and all constructs were labeled with lutetium‑177 (177Lu). [125I]I‑HPEM was coupled to ADAPT6 at the C‑terminus. Biodistribution of all constructs was evaluated in NMRI mice 4h after injection. Specific binding to HER2‑expressing cells invitro was demonstrated for all constructs. No significant difference in kidney uptake was observed between the [177Lu]Lu‑2,2',2",2"'‑(1,4,7,10‑tetraazacyclododecane‑1,4,7,10‑tetrayl)tetraacetic acid‑GLGK‑conjugates and the controls. The renal activity of [125I]I‑HPEM‑ADAPT6 was significantly lower compared with all other constructs. In conclusion, the incorporation of the cleavable GLGK‑linker did not result in lower renal retention. Therefore, the present study emphasized that, in order to achieve a reduction of renal retention, alternative molecular design strategies may be required for different targeting agents.

Scalable substrate development for aqueous sample preparation for atom probe tomography.

Reliable and consistent preparation of atom probe tomography (APT) specimens from aqueous and hydrated biological specimens remains a significant challenge. One particularly difficult process step is the use of a focused ion beam (FIB) instrument for preparing the required needle-shaped specimen, typically involving a "lift-out" procedure of a small sample of material. Here, two alternative substrate designs are introduced that enable using FIB only for sharpening, along with example APT datasets. The first design is a laser-cut FIB-style half-grid close to those used for transmission-electron microscopy, that can be used in a grid holder compatible with APT pucks. The second design is a larger, standalone self-supporting substrate called a "crown," with several specimen positions that self-aligns in APT pucks, prepared by electrical discharge machining (EDM). Both designs are made nanoporous, to provide strength to the liquid-substrate interface, using chemical and vacuum dealloying. We select alpha brass a simple, widely available, lower-cost alternative to previously proposed substrates. We present the resulting designs, APT data, and provide suggestions to help drive wider community adoption. Lay Description Atom probe tomography (APT) maps the composition of solid materials in three dimensions with sub-nanometre resolution. Preparation of specimens from aqueous specimens remains a significant challenge. To aid with preparation, we introduce here two substrate designs that can hold suitable volumes of liquid for freezing, prior to shaping the final specimen into a sharp needle for APT by using cryogenic focused ion beam milling. We also describe the complete setup that we designed for handling these substrates, including dedicated sample holders. Both substrates are made nanoporous, to provide strength to the liquid-substrate interface, using chemical and vacuum dealloying of alpha brass a simple, widely available, low-cost material. We finally showcase APT data and provide suggestions to help drive wider community adoption. This article is protected by copyright. All rights reserved.

A rapid spectroscopic method for the identification of the filamentous fungi isolated from Turkish traditional mold-ripened cheeses

Fourier transform infrared spectroscopy (FTIR) is an alternative microbial identification technique due to its faster analysis times and lower cost compared to molecular methods. In this study, forty-three fungal strains isolated from different Turkish traditional mold-ripened cheeses representing nine different Penicillium species (P. roqueforti, P. corylophilum, P. before, P. crustosum, P. spinulosum, P. rubens, P. brevicompactum, P. paneum, and P. solitum) were analyzed by using FTIR HTS-XT (High Throughput Screening Extension) method in the 4000–400 cm−1 wavenumber range. The spectra of the isolates were evaluated, and the chemical structures corresponding to the fungus-specific spectral regions were determined as fatty acids (3600–2800 cm−1), amide I and amide II of proteins and peptides (1740–1500 cm−1), polysaccharides (1200–900 cm−1) and carbohydrates (900–600 cm−1). The isolates were grouped according to the hierarchical clustering analysis (HCA) by applying chemometrics combined with FTIR spectroscopy. Results showed that FTIR spectroscopy has a high capability for rapid determination of cheese fungi based on their FTIR spectra.

Vortex circular airy beams through leaky-wave antennas

A novel method to design leaky-wave antennas radiating vortex cylindrical Airy beams at microwave frequencies is here presented. Two different approaches are adopted to produce waves with a nonzero orbital angular momentum (OAM): one based on a bull’s eye design excited by a uniform circular array of vertical coaxial probes with proper azimuthal phase delay, and one based on a single coaxial feeder exciting a multi-spiral radiator. Both of them take advantage of backward radial propagation of cylindrical leaky waves promoting circular Airy beams with vortex patterns. The OAM state can be changed by either varying the probe phasing or the number of spiral units. A reference profile is designed under transverse-electric and transverse-magnetic excitation independently. Numerical full-wave analysis are performed using different angular states to validate the antenna design, as well to highlight the different advantages of the two alternative design approaches.

A transdisciplinary multiscaled approach to engage with green infrastructure planning, restoration and use in sub-Saharan Africa

The systematic integration of green infrastructure (GI) concepts in urban planning shows promise to reduce environmental hazards; while creating sociocultural benefits. However, cities in sub-Saharan Africa face rapid urbanisation and are challenged by the degradation of existing GI, increasing their vulnerability to climatic risks. This paper presents the findings of a transdisciplinary research project that investigated GI planning in the City of Tshwane, South Africa, over two years. The researchers conducted a community survey, an on-the-ground rapid assessment of multifunctional benefit provisions, first-hand observations of local stormwater systems, reviewed policy documents and conducted semi-structured interviews with metro officials. To integrate the above findings, four design studios and eight co-creation workshops were held that explored GI spatial planning in the city. The researchers examined the uptake of GI planning principles, and the challenges, opportunities and local proposals for GI applications, and here synthesised some main conclusions. Despite many well-known challenges, GI opportunities include creating socioeconomic incentives for stronger human-nature relations, providing for multifunctional benefits and anchoring GI in local communities. Interactive research can facilitate increased local awareness and engagement, but access to GI benefits is physically constrained and socially determined by knowledge, networks and safety factors. Based on the above findings, the researchers propose locally adapted planning strategies to enhance GI: creating opportunities for GI access and co-ownership, encouraging multifunctional, safe and flexible GI, supporting multiscale GI integration, and strengthening collaborative governance. A joint GI vision can reinforce city ownership along with flexible and creative design alternatives that are rooted in local communities.

Experimental study and simulations of hydrogen cooling effectiveness for aviation PEM fuel cells

Proton exchange membrane fuel cells (PEMFCs) are seen as one possible future means of driving the change towards a zero-emission society. In a civil aircraft, fuel cell systems can have multiple potential benefits, such as reduced noise, lowered emissions and higher fuel economy compared to jet aircraft. For controlling the fuel cell temperature, thermal management systems are required which can be optimized for aircraft applications regarding their weight and reliability. In this work, a simplified and light-weight thermal management system relying on hydrogen cooling is presented and analysed. To investigate the feasibility, a test rig and a three-dimensional, singular channel model in ANSYS Fluent were designed. Fuel cell temperature could be maintained within the set threshold in the model and the test rig, thus showing that controlling the fuel cell temperature via the hydrogen reactant flow is a viable alternative thermal management system. Results from the model indicate that both the hydrogen mass flow and hydrogen inlet temperature should be used to control the fuel cell temperature. Furthermore, operating the fuel cell at medium to low current densities is favourable for hydrogen cooling. Future studies will explore alternate flow field designs to facilitate thermal management system relying on hydrogen.

Exploring global accessibility of deep ocean water for sea water air conditioning (SWAC) process: Identifying feasibility areas depending on temperature source

Sea Water Air Conditioning (SWAC) technology is a highly efficient alternative to conventional air conditioning system using renewable marine energy to provide cooling to buildings. However, its implementation requires access to Deep Ocean Water (DOW) at 4–5 °C, thus SWAC is only viable in coastal regions. Furthermore, one of the major obstacles to its global development is the investment cost that remains high. This cost is strongly linked to the bathymetry of the installation location as it determines the length of the drawing pipeline, which accounts for the largest share of the investment cost. Knowing the temperature and bathymetry profiles will enable the establishment of the financial viability of SWAC technology in a specific location. This paper presents an analysis identifying areas of feasibility on a worldwide scale for standard SWAC implementation first. Then, it explores an alternative design with a higher drawing point for seawater at 12 °C (coupled with a High Temperature District Cooling), which reduces the cost by shortening the drawing pipeline and allows for more locations to be suitable for this technology. Additionally, the impact of the El Niño/Southern Oscillation (ENSO) is also considered since a shallower drawing point makes it more sensitive to temperature variations.

Assessment of marsh terrace designs for wave attenuation utilizing a wave model

The northern Gulf of Mexico is facing high rates of wetland loss due to subsidence and sea level–rise, which has encouraged the application of various wetland restoration techniques. Marsh terracing is a restoration technique that has been implemented since the early 1990 s in Texas and Louisiana, yet few studies have been conducted to evaluate its effectiveness. Marsh terraces are segmented berms of soil built in coastal ponds that were once vegetated marshes. Marsh terracing is hypothesized to dissipate wind waves, encourage marsh expansion, and reduce shoreline erosion. This study (1) assessed the effectiveness of the most common terrace shapes (linear, chevron, and square) and spacing (100, 110, and 120 m) at reducing significant wave height (Hs), (2) assessed the effectiveness of alternative terrace designs for reducing Hs during different wind conditions, and 3) estimated the construction costs of alternative terrace designs. The Simulating WAves Nearshore (SWAN) model was used to simulate wind–driven waves in ponds with real and hypothetical terrace designs. Results revealed that: (1) The chevron shape provided the greatest reduction in Hs during all wind conditions, reducing Hs by up to 54%. (2) Hs reduction was not affected by terrace spacings. (3) Based on wave attenuation, the chevron design with a 120 m terrace spacing provided the optimal outcome with an estimated construction cost/ha of $6332 in a 250,000 m2 site compared to the terrace shapes and spacings evaluated in this study. This study will help coastal managers design marsh terraces to address wetland erosion in the Gulf of Mexico and other coastal areas facing similar environmental problems.

Adapting dose-response methodology to improve clinical trial design for psychotherapies.

Conventional randomized controlled trials (RCTs) have long served as the foundation of research in clinical psychology; however, most treatments for eating disorders show only modest effects on reduction of symptoms and maintenance of long-term remission. New options for psychotherapy treatment development research, beyond continuing to pursue additive or subpopulation approaches, are needed. One option is to apply dose-response designs, which are commonplace in studies of pharmacology, toxicology, and medical research, and characterized by the evaluation of the amount of exposure (dose) to an intervention, and the resulting changes in body function or health (response). Eating disorder interventions are particularly well-suited for dose-response treatment designs. The deadly nature of eating disorders makes it imperative that patients are not turned away for not being "ready" to engage with treatment. By identifying optimal doses, research will likely yield a more parsimonious course of treatment, which will lend itself to reduced costs, greater uptake, and reduced drop-out. Limited use of within-subject designs in trials for patients with eating disorders has produced fast-track efficacy studies and omitted key elements in the treatment development pathway. To decrease reliance on RCT's, dose-response methods should be applied as an alternative study design. Eating disorders are associated with medical and psychiatric comorbidities, poor quality of life, and high mortality. Access to evidence-based services for patients with eating disorders is limited, and identifying additional effective treatment options can be difficult because of challenges inherent to randomized-controlled trials. This manuscript describes an alternative trial methodology to maximize the information that can be gathered prior to utilizing a standard large-scale efficacy design.
