As an efficient approach to create garments with a designer's Kansei, we developed a method for three-dimensional (3D) garment modeling with sleeves by deforming a 3D reference clothing model according to the contours of garment images with the aim to apply it to garment patternmaking. We determined an appropriate reference bodice model from various dress forms. We made the reference sleeve model by sweeping the armhole of a dress whose armhole was on a plane. Using this method, we obtained models of two jacket bodices and sleeves by deforming each reference clothing model using the contours of jacket images from the front and side views. After adjusting the positions of the 3D models of the bodice and sleeve, we obtained jacket models with a sleeve. We obtained the jacket armhole from the intersection of the surfaces of the bodice and sleeve models. We successfully made 3D garment models and armholes using the proposed method. We also obtained bodice and sleeve patterns that reflected the armhole. The simulated patterns exhibited a similar clothing shape to the images with curved shapes along the arm. Thus, we demonstrated that the proposed method efficiently reflected the designer's Kansei clothing model. [ABSTRACT FROM AUTHOR]

The cooling jackets of liquid rocket engines are composed of narrow passages surrounding the thrust chambers and ensure the reliable operation of the engine. Critical conditions may also be encountered, since the cooling jackets of cryogenic engines, such as those using LOX/LCH4 propellants, are based on a regenerative strategy, where the fuel is used as a refrigerant. Consequently, deterioration modes near where pseudocritical conditions are reached or low heat transfer coefficients where the fuel becomes a vapour and must therefore be managed. The verification of the cooling jacket behaviour to consolidate the design solutions in all the extreme points of the operating box represents a very important phase. The present paper discusses the full characterization of the HYPROB (HYdrocarbon PROpulsion test Bench Program) first unit of the final demonstrator, (DEMO-0A), by considering the working points within the limits of the operating box and comparisons with the nominal conditions are given. In this way, a full understanding of the cooling system behaviour, affecting the working of the entire thrust chamber, is accomplished. Moreover, the design strategy and choices have been confirmed, since the verifications also include potentially even more extreme conditions with respect to the nominal ones. The investigation has been numerically performed and supported the thermo-structural analyses accomplished before the final firing campaign, completed in December 2022. Since little information is available in the literature on LOX/LCH4 engines, suggestions are given as to the organization of the numerical simulations, which support the design of such rocket engine cooling systems.

This paper investigates experimentally the structural performance of substandard reinforced concrete (RC) short columns confined with steel-reinforced grout (SRG) jackets under monotonically increasing uniaxial compression. The study comprised 24 square cross section short RC columns having alternative arrangements of shear reinforcement (ratio of stirrup spacing to longitudinal bar diameter ranging from 4.2 to 12.5). The short columns were retrofitted with externally applied SRG jacketing differing by the density of the fabric (4 cords/in and 12 cords/in) and the number of fabric layers (1 and 2). The test results showed that retrofitting significantly changed the behaviour of the specimens compared to the unconfined counterparts. For columns at risk of premature failure due to insufficient support of compression bars provided by the sparse stirrups, the SRG jackets delayed bar buckling, enabling the members to achieve greater strength and deformation capacity. The well-detailed specimens helped establish the maximum effectiveness of SRG confinement. [ABSTRACT FROM AUTHOR]

The pulmonary function test (PFT) induction jacket was invented to make the process of performing the forced vital capacity (FVC) manoeuvre with a computerized spirometer effortless and productive for both the patient and the medical practitioner. The jacket is composed of three layers of PVC material sealed together to form a single jacket with two chambers. The inner chamber is formed between the inner layer and the middle layer, in which cold water at a temperature of 10 °C is circulated using a connected water unit when triggered. Similarly, the outer chamber is formed between the middle layer and the outer layer, in which air is pressurized using a connected air unit. Thirty volunteers performed the FVC manoeuvre with and without wearing the jacket. There was no difference between the results in spirometry parameters in the participants without a jacket and those with a jacket. However, use of the jacket significantly reduced the number of trials the participants had to undergo to perform spirometry. The jacket automated the FVC manoeuvre by triggering a physiological inspiratory gasp using cold water and circumscribing pressurized air for expiration. Additionally, subsequent advancements in the jacket have been suggested. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to present a fit prediction case study of virtual twins of women jacket. For this reason, several basic principles of clothes fit prediction were developed and verified. Design/methodology/approach: To develop the principles of fit prediction, the women's jacket sleeve was selected as the study object. The study objects were categorized into three types: the patterns and two virtual sleeves generating on full avatar from Clo3D and on dummy (arm partly removed). Through series of subjective and objective evaluation experiments, the relationship between the similar indexes of the patterns and the virtual sleeves was built, including fit criteria range, the categorization of the indexes in terms of its sensitiveness, and the linear regressions to predict several indexes of virtual sleeves after its pattern parameterization. The results obtained were verified in case study by the virtual and real sleeves generating. Findings: The proposed principles of clothing fit prediction based on parallel research of the flat patterns and its virtual 3D shapes. The principles include the choosing of virtual twins of human body for virtual try-on, the establishing of indexes common schedule for patterns and virtual sleeves, the creation of criteria and its ranges for perfect fit and poor fit evaluation, and the application of existing relations between the patterns and the sleeves for predicting indexes responsible for fit. Research limitations/implications: The authors propose and verify the validity of the principles to predict several parameters of virtual 3D sleeve of women's jacket which are forming the level of fit. The result of this study can be used to convenient fit prediction and to find the misfit reasons. Practical implications: This study developed basic principles for predicting the fit of the clothing through the virtual simulation and the statistical analysis. Through studying the jacket sleeve, the several related ranges, the row of more sensitive indexes, and the equations were presented and verified, which certified the validity of proposed principles. Social implications: The results can effectively predict the sleeve fit before sewing, which reduce the time and materials cost and the operator's skill requirements. Originality/value: The authors propose and verify the validity of the principles to predict several parameters of virtual 3D sleeve of women's jacket which form the level of fit. The result of this study can be used for convenient fit prediction and to find the misfit reasons. [ABSTRACT FROM AUTHOR]

Jacket framing arrangement X, K, V and single bracing systems used in jackets influence the ultimate strength and redundancy in the system. Experimental investigation was conducted on a 2D frame (1:20) with two different bracing patterns (2D-1 and 2D-2) the results are compared with that obtained from nonlinear pushover analysis. Parametric assessment of Reserve Strength Ratio has been carried out on three bracing patterns, namely 3D-A, 3D-B and 3D-C using non-linear pushover analysis including pile-soil interaction. It is observed that RSR increases by 15% for X brace configuration (2D-2) compared to single brace configuration (2D-1). The RSR for 3D-B is found to be higher by be 35 % and 12% compared to bracing patterns 3D-A and 3D-C respectively. The brace pattern 3D-C exhibits similar strength to 3D-B, illustrating the insignificance of the brace at the top bay and this leads to reduction in wave loads on the system. [ABSTRACT FROM AUTHOR]

Large‐scale tests of shear‐dominated walls with ultra high‐performance fiber‐reinforced concrete (UHPFRC) jackets have shown the high effectiveness of this retrofitting solution. The jackets can suppress brittle shear failures and result in a ductile response governed by yielding of the flexural reinforcement. In addition, due to the low porosity of UHPFRC and the crack control provided by the fibers, the jackets can also provide an effective corrosion protection. However, while this retrofitting solution is very promising, there is a lack of mechanical models that can predict the effect of UHPFRC jackets. This paper proposes such a model based on a three‐parameter kinematic theory (3PKT) for reinforced concrete walls. The 3PKT is extended by modeling three important effects associated with the UHPFRC jackets: tension in the fibers across the critical diagonal cracks, increased compression resistance of the critical loading zones, and enhanced crack control. The results show that the proposed approach can be used to design the properties of UHPFRC jackets in order to achieve a desired structural response in terms of strength, ductility, and crack control.

The construction of deep-sea and offshore wind farms is key to the development of offshore wind power. Since the forms of bottom supporting structures and their installation methods greatly affect the overall cost of electrical platform, the latest developments in this filed were reviewed, based on which a novel integrated floating method was introduced. First, by incorporating the advantages of the integrated offshore wind turbine and the installation method for suction bucket foundation, the idea of integrated floating and quick installation based on a four-bucket jacket foundation was proposed. Second, the process of integrated wet towing of the four-bucket jacket foundation was described, which was further verified via indoor model experiments and numerical simulations. Results show that under 2 m wave height and level 5 sea conditions, the proposed four-bucket jacket foundation can be wet towed and floated at a speed of 5 knots under the optimum draft depth.

Jacketed pressure vessels are pressure vessels used for either heating or cooling the vessel. This type of pressure vessel is subjected to several loads under its operating conditions which generates maximum stress at the jacket closure. The maximum stress at the jacket closure affects the performance and life cycle of the jacketed vessel. The present study aims to optimize the jacket closure design to which minimum or a considerable amount of equivalent stress is generated. The numerical model of jacket closure was developed in Ansys Workbench in order to optimize the design of jacket closure. The Taguchi method with orthogonal L27 array is adopted to experimentally analyze the effect of jacket closure thickness, closure angle, and closure radius. S/N ratio smaller-the-better is used to study the influence of these parameters on maximum equivalent stress-induced and to get the optimum design parameter set for jacket closure. ANOVA is used to find the parameter which affects the equivalent stress significantly. The prediction model of the maximum stress induced at the jacket closure has been developed and validated with the virtual experiments of stress analysis. The current study provides the pressure vessel industry a prediction model for the accurate selection of jacket closure design parameters without the need for trial experiments with various jacket closure materials. It was observed that jacket closure thickness has the maximum influence on the stress induced followed by jacket closure angle. However, inner closure radius has very less influence on the stress generated at the jacket closure. [ABSTRACT FROM AUTHOR]

In order to reduce the functional degradation caused by improper daily washing-care and prolong the service life of technical jacket, the relationship between the daily washing conditions and functional degradation in the wearing performance of technical jacket (waterproof, windproof, warmth retention) was quantitatively investigated with the help of hydrostatic pressure, surface contact angle, air permeability, warmth retention, and scanning electron microscopy (SEM) of technical jacket after different daily washing conditions. Results showed that no matter what kind of washing modes, washing parameters, type and dosage of detergent, the wearing performance of technical jacket after washing were subjected to decrease compared with pre-washing. Additionally, it was also found that the effects of washing modes, type of detergents and washing parameters on the wearing performance of the technical jacket were significant, instead of the dosage of detergents. This indicates it was possible ways to minimize functional degradation by setting optimal washing conditions (washing parameters, washing mode, types and dosage of detergent). Balancing considerations of functional degradation and washing efficiency, the washing combination of mechanical agitation + micro-nano bubbles), type of detergent (neutral liquid detergent), dosage of detergent (3 g/L), water temperature (20°C), main washing bath ratio (1:10), main washing speed (15 rpm), main washing time (20 min), rinsing speed (30 rpm), rinsing cycles (2), belonged to the optimal washing combination in this study of washing condition. The results were of practical significance to guide manufacturers of washing machine to develop optimal daily washing produce for outdoor clothing, especially technical jacket.

Since G. Thomas Tanselle published his 1971 essay "Book-Jackets, Blurbs, and Bibliographers", dust jackets have gained increasing scholarly attention as the "raw material of publishing history."[2] Tracing early examples from the 1830s through the (then) present day, Tanselle concludes that dust jackets are an "important class of primary material" and provide publishing historians with information ranging from price and impression figures to biographical information about authors.[3] In his follow-up article, "Dust-Jackets, Dealers, and Documentation", Tanselle develops his understanding of dust jackets, arguing that not only do they "display the work of interesting or significant designers and illustrators" but that, for publishing historians, they show "something of the publisher's taste and [...] the style of the times." Publishers regularly ordered far more dust jackets than the number of books printed: the initial print run of King's I The Dark Glasses i (1954), for instance, was 7,500 books but 8,200 dust jackets.[54] While some of this overprinting accounted for wastage, these jackets were important tools for publishers' travelers, agents, and sales departments - as stand-ins for the book prior to the appearance of proof, review, and other pre-publication copies or as marketing material to overseas locations where dust jackets were cheaper to ship than hardcover books. The Typographical Dust Jacket While distantiating the text from its cover illustration through a heterosexualized image preserved the illustrated jacket and obscured the text's queer understandings, for some queer texts publishers instead felt forced into a more radical approach: no cover illustration at all.

The jacket is the most widely-used fixed foundation for offshore wind turbines due to its superior strength and low installation cost in relatively deep waters. Floating crane vessels are commonly used to install jacket foundations. However, the dynamic coupling between the jacket and the floating vessel might generate complex dynamic responses under wave action. The complexity of the multi-body system requires comprehensive time-domain simulations and statistical analysis to obtain reliable results, especially for the evaluation of the operational safety of offshore lift installations of a jacket foundation. In this context, this study performs numerical simulations and statistical analyses to predict the extreme responses and the preliminary allowable sea states for guiding the lowering operation of a jacket using a floating crane vessel. First, ANSYS-AQWA is used to obtain the hydrodynamic coefficients of the vessel in the frequency domain. A nonstationary time-domain simulation of jacket lowering with winches is performed to identify several preliminary critical vertical positions of the jacket from the time series in an irregular wave. The extreme responses of a target probability are evaluated by the extreme distribution model after a large number of steady-state time-domain simulations of the critical vertical positions in irregular waves. The most critical vertical position is determined from three preliminary critical vertical positions by comparing the extreme responses. Eigenvalue analysis and spectrum analysis of the most critical vertical position of the jacket are carried out to find the natural periods of the system and the dynamic coupling characteristics between different components. The influence of wave direction, significant wave height, and spectrum peak period on the dynamic responses are also analyzed in the most critical vertical position. Furthermore, the optimal wave direction is determined as the head sea. Preliminary allowable sea states are derived by comparing the calculated dynamic amplification coefficient with the defined operational criteria. [ABSTRACT FROM AUTHOR]

This study aims to analyse how jacket-supported OWTs functioning in three different operational modes (power production, emergency shutdown and parked mode) respond to seismic actions when subject to different incoming wind directions and ground motion shaking directions. To do so, the seismic response of the NREL 5 MW OWT founded on the OC4 jacket substructure is simulated using an OpenFAST model that includes multi-support seismic input, soil–structure interaction and kinematic interaction. The impact of the working conditions and of the directionality of the loads on the jacket substructure is analysed and discussed. The tower top accelerations and displacements are examined for different sets of cases, and the seismic response of the jacket is studied in terms of internal forces and von Mises stresses along the different levels of the substructure. The results show, and quantify, the relevance of considering the different operational modes for a correct design of the substructure and of the foundation. The maximum structural stresses within the jacket substructure appear almost always in power production, with the exception of the top part of the legs, where higher stresses arise during emergency shutdown in several cases. • Seismic response of NREL 5 MW OWT on the OC4 Jacket for different operational modes. • Emergency stop is not necessarily beneficial in reducing accelerations at the RNA. • Emergency stop tends to produce the largest stresses at the top of jacket. • Power production tends to produce the largest stresses within the rest of the jacket. • The influences of wind direction, shaking direction, and misalignment, are quantified.

The column is the most important structural element were strengthening of columns became a demanding issue. In this paper, the effectiveness of strengthening reinforced concrete (R.C) columns with carbon fiber reinforced polymers (CFRP) wraps has been improved by increasing the contact area between the column’s surface area and CFRP. A new strengthening technique was hired for the purpose of enhancing the efficiency of CFRP jackets in improving the load capacity of R.C columns, especially columns with rectangular sections. The method is based on increasing the contact area between the CFRP jacket and the column's surface area. This was done by adjusting the profile of the col's cross-section to almost ellipsoidal. The experimental program in this research includes testing 13 columns to include all test parameters, the shape of the cross-section, and the cross-section profile. The results include axial stresses and corresponding axial strains, and lateral strains at the mid-height and quarter height of tested specimens. And also, the cracking load and maximum load with crack patterns are determined. The comparison involved the study of the effect of the traditional CFRP jacket wrapping of R.C columns with square, and rectangular sections and the newly developed strengthening technique. A theoretical study was also conducted. Where the capacity of the square and rectangular confined columns with different radius of curvature, R, of the ellipsoidal profile is determined by the predicted and design equations. The study revealed that the strengthening technique is expected to effectively enhance the efficiency of the CFRP strengthening technique, especially for columns with square and rectangular sections as the area of the well-known dead zone of these columns is reduced using the proposed technique. Also, the results proved that the efficiency of strengthening tested columns by CFRP jacket has been enhanced using the strengthening technique by about 80% of original RC columns, which exceeds the traditional method (Jacket) CFRP wrap by 60%.

Background: Benign paroxysmal positional vertigo (BPPV) causes vertigo in patients. It is the most common type of peripheral vestibular disorder. The patient will have vertigo symptoms while moving the head. The symptoms are usually severe and have duration of seconds. Objective: To study the efficacy of modified Dix-Hallpike test by using pillow jacket for diagnosis of BPPV patient. Materials and Methods: The first group was evaluated by using the traditional Dix-Hallpike test and then re-evaluated using the modified Dix-Hallpike test by using pillow jacket, while the modified Dix-Hallpike test was done using pillow jacket and then the traditional Dix-Hallpike test was done in the second group. Patients were assessed for nystagmus using Frenzel glasses recording duration, latency period, and direction of nystagmus. Following completion of the test, each patient was evaluated for pain, ease of use, and level of comfort by using the VAS scale. Results: Ninety-six patients were recruited into the present study. Forty-eight participants were included in Group 1 using the traditional Dix-Hallpike and then the modified Dix-Hallpike test by using pillow jacket, while forty-five patients were in Group 2 using the modified Dix-Hallpike test by using pillow jacket and then the traditional Dix-Hallpike. There were no significant differences regards to age, gender, laterality, duration of vertiginous symptoms in each attack, or onset of symptoms. No statistical significance was noted in terms of median VAS scores for pain, comfort, or ease of use between the two groups. The sensitivity of the modified Dix-Hallpike test by using pillow jacket was 94.92%, while specificity was 91.43%. McNeMar Kappa tests were equivalent for both the modified Dix-Hallpike test by using pillow jacket and traditional Dix-Hallpike test. Conclusion: The modified Dix-Hallpike test by using pillow jacket may be reliable, with both high sensitivity and specificity in diagnosing BPPV. This method can be used to assess patients suspected of posterior canal BPPV in cases there is lack of space for head extension, or the patient is unable to change position easily as with the traditional Dix-Hallpike maneuver.
