Resumen

An experiment was conducted at the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur-1706 from March to June 2014 to evaluate growth and yield performance of sesame genotypes. Five sesame genotypes i.e. DB-6992, BD-6995, BD-7001, BD-7011 and Hathazari-4 were used in the study. The genotypes significantly differed in photosynthetic rate, dry matter partitioning and seed yield. The earliest genotype was Hathazari-4 and the latest was BD-7011. The highest stem dry weight, leaf dry weight, capsule dry weight, leaf area index, light interception, photosynthetic rate were recorded in genotype Hathazari-4. The number of capsules plant-1 and the number of seeds capsule-1 were also highest in the genotype Hathazari-4, while the lowest was being noticed in the genotype BD- 7001. Weight of 1000-seed was the maximum in genotype BD-6992 and the minimum in the genotype BD- 7011. The highest seed yield (3.52 tha-1) was recorded in the genotype Hathazari-4 and the lowest in the genotypes BD-6992 followed by BD-7001. The highest oil content (41.39%) was recorded in the genotype BD-6992 and the lowest (39.72%) in the genotype Hathazari-4 but the highest oil yield (1.53 t ha-1) was recorded in the genotype Hathazari-4. It may be concluded that the sesame genotype Hathazari-4 may be cultivated for higher seed yield and oil production.Bangladesh Agron. J. 2016, 19(1): 19-28

Resumen

Two configurations for a unicycle, a class of nonholonomic systems, is looked into. The first configuration is the case where the generalized coordinates consists of four parameters, while the other configurations consists of five. For both systems the equations of motion are calculated. Then a method for parameterizing a desired path for the systems using a synchronization function among all degrees of freedom is shown. A set of equations to find feasible trajectories keeping the desired path virtually constrained is calculated. It is then shown for the four degree of freedom system how to compute the transverse linearization, which can be used for orbital stabilization of a desired motion consisting of circular orbits or straight paths. A way to compute a periodic controller for a linear time varying system is derived, and a set of controllers are tried out on the four degree of freedom unicycle with negative result.

Stowell, Alison. "Organizing e-waste". Thesis, Lancaster University, 2012. http://eprints.lancs.ac.uk/70211/.

Resumen

Over the past thirty years the reliance on Information Communication Technologies (ICT’s) has generated a new form of waste called e-waste. E-waste is one of the fastest growing waste streams. It is well known that ICT’s contain materials that, without proper care, are harmful to the environment. The EU responded to these concerns through the creation of the Waste of Electronic and Electrical Equipment (WEEE) Directive, introduced into the UK in 2006. WEEE aims to control electrical and electronic waste through the promotion of reducing, reuse, recycling and recovery. The intention is to improve the environmental profile of those operating within the waste sector with the intention of protecting soil, water and air pollution and to preserve valuable resources. Despite the raised awareness of the problems e-waste contributes globally there is a limited understanding of the significance of the growth of the new form of waste and, specifically, local enactments of waste management. The focus of this thesis is how six organizations within the computer recovery sector have adopted the WEEE legislation. Insights from neo-institutional theory provide an aid to understanding the impact that the legislation has had on the working practices of six organisations dealing with e-waste. An action research approach was adopted for the field research as a means of collecting and analysing qualitative data. In this thesis three arguments are developed. First is that the implementation of the WEEE legislation rests upon the initial categorization of a computer at the point of disposal. Categories relating to waste are not static, but constantly evolving as local negotiation takes place between dominant actor groups. The findings support how categorization determines the trajectory of a computer and plays a crucial role in influencing and reinforcing the boundaries around associated working practices. Second, that the WEEE legislation has created a framework through which institutional entrepreneurs have been able to both bring about changes in their organisation but also to stabilise specific working practices. Institutional entrepreneurs achieve this by mobilising changes to the products and services their organization offers in the context of an emergent institutional field and by reinforcing their occupational identity. Third, that legislation has raised awareness of the complexity of computer design and the multiplicity of disposal practices, but it has also reinforced long-standing associations of waste as a particular type of occupation with specific organizational practices.

Resumen

Cancer of the brain and CNS account for only 2% of new cancer cases in the UK however it is responsible for 7% of cancer deaths of those aged under 70 years of age. Although surgery falls short of a cure it is the primary method of treatment. Two of the key problems in tumour surgery in the brain are a) that many tumours are visually indistinguishable from normal tissue even for experienced surgeons and b) that the risk of post-surgical neurological deficit is related to the proximity of functional (or 'eloquent') neurological tissue. In collaboration with surgeons at the Southampton University NHS Hospitals Trust we seek to address both of these problems. Firstly there is literature evidence that normal and neoplastic tissue have different spectral characteristics in the visible and near-infrared region. We investigate whether these can be practically imaged intraoperatively to establish disease state. Secondly the redox state of haemoglobin is known to affect it's visible and near-infrared spectral characteristics. This project investigates whether it is possible to identify the haemodynamic response associated with functional activity intraoperatively in the human brain. Prion diseases are fatal chronic neurodegenerative diseases of animals and man. They have gained notoriety due to recent outbreaks of Bovine Spongiform Encephalopathy (BSE) and the evidence that they can be transmitted between species, including to man. Exposure to BSE infected material has been shown to cause variant Creutzfeldt-Jacob disease in man. Prion disease is also used as a model of other neurodegenerative diseases, such as Alzheimers disease. Remarkably little is known about this class of disease including the specific cause of the neurodegeneration. Prions are a mis-folded protein which have a different conformation than the normal protein. Certain spectral features in the mid infrared region are associated with protein conformation. In collaboration with neuro-biologists within the university and using a synchrotron light source we investigate the application of multispectral imaging in early stage prion disease. By analysis of the protein conformation sensitivity of the mid infrared spectra (with particular interest in the Amide I band) we seek to identify structurally relevant markers in a mouse model before clinical symptoms of the disease are evident. This may lead to better understanding of the disease progression and the neurotoxic element

Texto completo

Resumen

Muratori concepisce Studi per una operante storia del territorio come una lettura del territorio, una sua interpretazione. E’ una raccolta di disegni (255 disegni a mano e 18 prove di stampa), in cui sono riportati soltanto i tratti rilevanti dei territori considerati al fine dello studio. La tesi ha come obiettivo quello di compiere un’analisi filologica dei documenti e cercare di cogliere le finalità, valutando la sua attendibilità ai giorni nostri. Nella scelta del titolo, Studi per una operante storia del territorio. Il libro incompiuto di Saverio Muratori,inserendo nel titolo quello originale dell'opera, si rende esplicita l’intenzione filologica di base da cui si sviluppano le considerazioni fatte nello svolgimento di questa ricerca, costantemente attenta alla coerenza con i disegni analizzati. Questa coerenza è dettata dalla volontà di perseguire le logiche di confronto che hanno caratterizzato il lavoro di Muratori. Il titolo che descrive il corpus dei disegni mette in primo piano il sistema uomo-natura, che il territorio rappresenta nella sua totalità di unicum. La tesi è suddivisa in due parti. La prima verte sullo studio dei materiali d’archivio relativi agli Studi sul territorio, in cui è spiegato il metodo di catalogazione utilizzato. Fondamentale, ai fini di un primo approccio alla ricerca, è il contributo dato dall’architetto Alessandro Giannini attraverso la preliminare schedatura del materiale ed dell'analisi riportata in Leggendo le minute dell’Atlante del territorio di Saverio Muratori. La seconda parte della tesi verte su un percorso dialettico tra la filosofia, la teoria, la didattica e la pratica progettuale di Muratori, ambiti da tenere in considerazione per una interpretazione critica alla sua metodologia, che ha come fine ultimo il reale, quindi il territorio, in cui trova, prima attraverso la trattazione teorica esposta in Civiltà e territorio, la concreta conclusione nei disegni degli Studi per una operante storia del territorio.
The aim of this thesis is to provide an analysis of the drawings that compose Muratori’s Studi per una operante storia del territorio, a study which he conceived as a way to both read and interpret the territory. Studi per una operante storia del territorio is an unfinished project, and consists of a collection of (255 drawings and 18 printed materials) drawings, extensively studied here for the first time. The research presented here aims at providing a philological analysis of these drawings, so as to identify and reconstruct the thesis put forward by Muratori – the project, being incomplete, does not include a written description of the drawings. In his project Muratori focusses on reality by comparing his research with different aspects of society, and by critically evaluating comparison between his theoretical approach and the analysis, for the practical applications . This thesis - whose title (Studi per una operante storia del territorio. The unfinished book by Saverio Muratori) follows Muratori’s theoretical stance – is divided into two parts. The first section is devoted to the materials included in Studi per una operante storia del territorio, and to the method used for cataloguing the drawings. Crucial to the study presented here is Leggendo le minute dell’Atlante del territorio di Saverio Muratori, written by Alessandro Giannini: in this book (first published in this thesis) Giannini, assistant of Muratori, provides a detailed overview of the cataloguing process, and of the method used for the analysis. The second section presents an itinerary of the philosophical, theoretical, didactical and practical background of Muratori. This is needed to interpret and critically evaluate his methodology, whose final aim is the study of the “real” (i.e. the territory). First approached in Civiltà e territorio, this topic is finalised in Studi per una operante storia del territorio.

Texto completo

Resumen

Novel paramagnetic lanthanide complexes have been synthesised for use as probes for magnetic resonance imaging and spectroscopy. Initially, complexes containing a trifluoromethyl group were examined for 19F MRI/S, due to the large chemical shift range, favourable NMR properties, and the absence of a background signal in vivo. The use of paramagnetic lanthanide ions increases relaxation rates, allowing faster acquisition times and increased signal intensity per unit time. In addition, chemical shift non-equivalence is enhanced, which is important for the development of responsive probes. Examples are presented that report selectively on changes to citrate concentration levels in the presence of other anions or signal enzyme hydrolysis. To improve signal intensity for in vivo applications, conjugate systems have been developed containing a number of fluorinated lanthanide complexes covalently bound to high molecular weight adducts (glycol chitosan, PAMAM dendrimer). These systems resulted in one major species being observed in solution, despite the broad molecular weight ranges exhibited by these polymeric entities. Preliminary in vivo MRI studies in animal models were undertaken with the glycol chitosan conjugate. In order to enhance the signal further, a set of fluorinated complexes was synthesised containing a pyridyl moiety designed to increase the rigidity of the overall system, thereby reducing dynamic exchange broadening. Additionally, the 19F NMR spectra of these complexes displayed much larger lanthanide induced shifts than observed for the previous systems. By substituting the CF3 group for a tert-butyl moiety, the corresponding 1H NMR signal was shifted well beyond the standard diamagnetic range, leading to the development of a new series of complexes for use as 1H MRI and MRS probes. These complexes have been applied to preliminary in vivo MRI studies. A further system has been developed that displays pH-dependent behaviour, observed by both 1H NMR spectroscopy and in phantom imaging studies.

Resumen

This thesis attempts to study, in a comprehensive manner, the EEZ rule in both the LOS Convention and in state practice. Its central aim is to try to establish with exactitude the scope of the rule that has been taken into international custom. In this respect, after giving in chapter one a short exposé on the prevailing rules of the law of the sea that had governed all maritime spaces before UNCLOS III, serving as a background against which a better apprehension of the LOS Convention's EEZ provisions can be attained, an analysis of the rights of both coastal states and third states in the EEZ and their corresponding duties is provided in chapters two and three respectively. It has been asserted that, although a coastal state by claiming an EEZ would only enjoy specific functional rights, viz., the fields of activities they are connected with are explicitly defined, the vagueness often found in the wording of the Convention makes the situation not clear in all respects. While such a phenomenon may widen the functional limitations placed upon the general right of freedom of the high seas, it does not seem, however, to have any bearing on the high seas quality of the principal freedom of overflight, of laying cables and pipelines, and the freedom of navigation. Chapter four is a thorough examination and analysis of state practice as evidenced in EFZ and EEZ claims against the yardstick of LOS Convention. This is followed by a last chapter determining the scope of the rule that has been picked up in the new custom relating to the EEZ. In this connection, it is asserted that state practice gives strong evidence that a general right to claim a jurisdictional maritime zone as defined in Articles 55 and 57 of the LOS Convention, viz., extending seaward up to 200 miles from the baselines, is firmly established in international customary law.

Resumen

The research has explored the reality of generational renewal in agriculture in order to understand the entry process, the agricultural practices of young people and their attitudes toward a new agrosocial paradigm. The methodology combined qualitative and quantitative techniques based on a comparative analysis between Southern Ontario (Canada) and Catalonia (Spain). The first result is that the pathway to become a farmer is a process consisting of different phases where each profile shows different needs and abilities. The second result verifies how the practices and attitudes of young people vary depending on the family origin. The thesis also analyzes the most relevant results in policy terms. Finally the research shows the reality of an emerging group of young farmers who put in practice a new agrosocial paradigm. This group is made up by continuers and newcomers and we have called them "New peasantry".
La tesi doctoral ha explorat la realitat del relleu generacional de l’activitat agrària per entendre el procés d’incorporació, les pràctiques agràries de les persones joves i les actituds vers un nou paradigma agrosocial. La metodologia combina tècniques qualitatives i quantitatives a partir d'una anàlisi comparatiu entre el sudoest d'Ontario (Canadà) i les comarques gironines (Catalunya). El primer resultat és que el camí d’incorporació és un procés format per diferents fases on cada perfil de jove mostra unes necessitats i unes aptituds diferents. El segon resultat verifica com les pràctiques i les actituds dels joves varien en funció de l’origen familiar. La tesi també analitza les implicacions en termes politics dels resultats més rellevants. Finalment es mostra la realitat d’un grup emergent de joves que s’incorporen a l’activitat agraria possant en pràctica un nou paradigma agrosocial. Aquest grup emergent està format per pagesia tradicional i nouvinguda i s’anomena “Nova pagesia”.

Carnal transcendence and sexual difference -- An amorous exchange -- Angels playing with placentas -- Fluid subjects -- Poetics -- Oneiric spaces -- Conclusion.
Carnal transcendence imagines a world in which the carnal has the weight and value of transcendence, and the divine is as liveable and readily evoked as the carnal. Carnal transcendence offers a means of thinking through difference in the work of Luce Irigaray, who asks: "why and how long ago did God withdraw from carnal love?" (1991a, p 16). This thesis argues that Irigaray enables her readers to explore the relationship between carnality, transcendence and difference, but resists elaborating it in her work. Carnal transcendence as difference risks remaining an exercise in rhetoric, rather than the transformative and creative philosophy that Irigaray imagines. -- Irigaray's resistance to the carnal is evident in her arguments for sexual difference, which offers our "salvation" if we think it through, and heralds "a new age of thought, art, poetry, and language: the creation of a new poetics" (1993a, p 5). Note the language of transcendence used here. When considered in the light of carnal transcendence, sexual difference imagines a differently sexed culture. This thesis argues that Irigaray's writing is contradictory on this point: it articulates the plurality of women's sexuality, but emphatically excludes theories of sex and gender that emphasise multiplicity. This thesis challenges these limitations by exploring the possibilities of the "other" couple in Irigaray's writing-mother and daughter - for thinking through carnal transcendence as difference. -- This thesis not only explicates a theoretical model for carnal transcendence as difference; it also attempts to put into practice a poetics - a playful rewriting of theory. This celebrates the carnality of Irigaray's writing - evident in her complex imagery of the two lips, mucus, the placenta and angels-and enables an exploration of the philosophical space of the "new poetics" that Irigaray is attempting to engender.

Resumen

Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 1998.
Includes bibliographical references (v. 2, leaves 254-260).
In 1992, the National Commission on Severely Distressed Public Housing (NCSDPH) clearly established the need to revitalize some of the most distressed and isolated housing environments in the U.S. In response, the Department of Housing and Urban Development (HUD) created HOPE VI, initially a demonstration program that evolved to support revitalization and integration models not only for the dilapidated projects, but also for the equally distressed surrounding neighborhoods. This dissertation seeks to illustrate the complexity of implementing integration efforts that seek to reverse public housing isolation by addressing two premises: 1) the integration of public housing constitutes a complex social, economic, cultural and physical matter that can, nonetheless, be clarified and coherently categorized with the help of a cross-national sample of fifteen HOPE VI revitalization efforts; and 2) public housing isolation is a multi-faceted issue that can best be understood through careful historical and morphological analysis of an individual public housing development, such as Boston's Mission Main. The dissertation is structured to highlight the mechanisms of an "isolation to integration" dynamic by analyzing, in its first part, pre-redevelopment isolation conditions and integration strategies for a fifteen-city sample (Chapters 2 and 3); and, in its second part, by detailing that dynamic for the Mission Main case (Chapters 4 and 5). More specifically, Chapter 1 traces the origins of an isolationist project mentality and its impact on design during sixty years of policymaking. Chapter 2 introduces pre redevelopment conditions as well as revitalization strategies for each of the sampled developments. Chapter 3 classifies integration strategies according to physical, socioeconomic and organizational variables. Finally, Chapter 4 investigates the roots of present day isolation in Mission Main, while Chapter 5 details the complex implementation process that characterized the Boston example. Results show that public housing isolation has origins outside the development, as revealed by morphological analysis of embedded external forces; and that re-designing the social and physical connection between project and neighborhood is a complex process influenced as much by pre-redevelopment conditions as by the desires of residents, designers or policymakers to foster integration.

Resumen

This paper addresses the synthesis problem of Watt-I and Stephenson-IIIa six-bar linkages motion generation for four specified task positions. Both of them have one thing in common — theirs floating links which used as end-effectors are connected to a coupler plane of a four-bar linkage. Once the task positions of end-effector are given, we can calculate the corresponding positions of the coupler plane. Then our focus is on the synthesis of a four bar-linkage and the way that a RR chain can be attached to constrain the links of this four-bar linkage. This synthesis problem of four-bar linkage motion generation can be settled by a solution region method. And then we can present an equation of pivot curve that each point on this curve can generate a satisfactory RR chain. A new local solution region that is more practicable is presented by the last numerical example.

Resumen

Ride comfort and handling characteristics are two important aspects of vehicle dynamics that generally require contrasting suspension settings. Different damper settings of the suspension system are required in order to meet these conflicting requirements. A magneto-rheological (MR) damper allows variable suspension settings to achieve enhanced ride comfort as well as handling characteristics by providing adaptable damping. Implementation of semi-active control requires an accurate MR damper model and online identification of model parameters. However, modeling a MR damper for a wide range of input conditions is challenging, especially when there are constraints on necessary measurements that are required for modeling. Although the available literature proposes various parametric models, many of these models are computationally expensive and are not viable for online identification. This paper presents a non-parametric model as well as a recursive model to predict the damping force of a MR damper in order to implement a semi-active control algorithm on an off-road vehicle. The results of the two models are compared to a conventional parametric model. The recursive model is used to demonstrate the significance of including the measured damping force in the model. Whereas the availability of the measured damping force yields a reasonably accurate model, the lack of measured damping force significantly impairs the recursive model.

Resumen

In this paper, we study a kinematic friction model of a single degree-of-freedom oscillating system. This model has the following dimensionless equation of motion: y″+2ζy′+y=-μky′ in which the kinematic friction is described by a quadratic function of the velocity as the following: μky′=μ0+μ2y′2sgny′+μ1y′ The sign function preserves the asymmetry of the friction force. The model captures most of the friction behavior that has been observed experimentally using a recent apparatus known as “dynamic oscillating tribometer”. This experimental setup is based on the non-linear free dynamic response of this kind of oscillator. However, this technique is able to carefully determine, with no need for any force transducer, the velocity-independent and velocity-dependent friction coefficients, μ0 and μ1 respectively, for a linear description of the kinematic friction, μk, around y′ = 0 where: μky′=μ0sgny′+μ1y′ In this context, the principal aim is to investigate numerically and analytically the effect of the additional quadratic term. To analyze the free dynamic response and their corresponding envelops, different numerical methods are performed. New characteristics of the envelops are discussed in detail with respect to the form of the kinematic friction coefficient. This allows a better comprehension of the results observed experimentally.

Resumen

A new class of actuated Spring-Loaded Inverted Pendulum (SLIP) models with hip actuation and leg damping has been developed, and is found to be more stable than the canonical version. However, it is not known how the addition of hip torque and leg damping change locomotion stability. In this paper, we study the effects of leg damping and hip torque on locomotion stability of actuated-SLIP models. All other modeling assumptions of SLIP are conserved. And hip torque is turned off during the flight phase. We show that for a given set of nondimensional SLIP parameters the hip torque and leg damping required for a periodic solution are not independent. Further, we show that adding hip torque and damping changes the dynamics of actuated-SLIP solutions in a non-intuitive way. When a very small amount of torque and damping are added the affect is initially to destabilize SLIP solutions. As torque and damping are added further, it eventually improves the stability properties of solutions.

Resumen

Remote rendering is employed when the visualization task is too challenging for the hardware used to display a dataset or when it is too time consuming to transfer the complete dataset. Volume visualization with its dataset sizes growing with the 3rd power of their spatial resolution is such a task. Since remote rendering introduces additional sources of latency, its applicability to virtual environments is limited because of the required low delays from user action to displayed image. We counter these latencies with image-based rendering techniques: color image data along with additional depth information is warped, while new data has not been completely received. Using these approximate images, it is possible to decouple the cheap display phase from rendering. While depth values are trivially deduced for polygons, we contribute heuristics for volumetric datasets with varying transparency.

Resumen

More and more manufacturing firms are transitioning to more serviced based offerings. It has been shown that a useful integrated bundle of services through a complimentary product can be a better business model than just adding support services to a product as tactical responses to customer needs. In order for companies to be able to define these integrated bundles in an efficient and systematic manner, a process is needed. In the paper we propose a new method to define modular services, ones that can be leveraged efficiently as driving entities, and which can be provided using several product offers. The service modules consist of services modularized for leveraging across several products. The method builds upon the foundations in product platform and modularity research extending it to product service systems. Further, we introduce alternative service modular platform leveraging strategies.

Resumen

Surge is a dynamic flow instability that can cause extensive damage to compressors and other components. One common challenge that many surge control methods in the literature face when implemented in industrial applications is the unavailability of the high performance actuators and accurate flow rate measurements that are required to suppress surge. In this paper we present experimental results of employing active magnetic bearings in order to suppress the surge instability in a centrifugal compressor. Also, we compare how the selection of the flow estimation method affects the effectiveness of the implemented surge suppression controller. Experimental data demonstrates that the best combination of controller and flow estimator tested in this work allows the compressor to operate deep into the former surge region when the controller is activated, moving the minimum flow rate at the surge initiation point by 21%. This allows the compression system to operate at the highest efficiency/pressure point in the characteristic curve, while still retaining a very conservative surge margin separating the allowed compressor operating region from the surge inception point even if unexpected system changes occur.

Resumen

This paper presents a new method in dynamics — The Moving Frame Method (MFM) — and applies it to analyze the roll, yaw and pitch of a ship at sea, as induced by an onboard moving crane. The MFM, founded on Lie Group Theory, Cartan’s Moving Frames and a compact notation from geometrical physics, enables this expedited extraction of the equations of motion. Next, the method deploys the power of the special Euclidean Group SE(3) and a restricted variation to be used in Hamilton’s Principle, to extract the equations of motion. The mathematical model is then simplified to get a clearer picture of the parameters that impact the motion of the crane. The equations of interest are numerically solved by using fourth order Runge-Kutta method to obtain the specific data for the motion induced by the crane. Then, The Cayley-Hamilton theorem is used to reconstruct the rotation matrix. To supplement the paper, a webpage is coded with a model of the crane and ship, to graphically visualize the motion in 3D. It is imperative to note that while there are many approaches to dynamics, the MFM presents a consistent method, from 2D to 3D, and across sub-disciplines. The simplification is what has enabled undergraduate students to undertake this project.

Resumen

Condensation of water vapor is an important process utilized in energy/thermal/fluid systems. When droplets coalesce on the non-wetting surface, excess surface energy converts to kinetic energy leading to self-propelled jumping of merged droplets. This coalescing-jumping-droplet condensation can better enhance heat transfer compared to classical dropwise condensation and filmwise condensation. However, the resistance force can cause droplets to return to the surface. These returning droplets can either coalesce with neighboring droplets and jump again, or adhere to the surface. As time passes, these adhering droplets can become larger leading to progressive flooding on the surface, limiting heat transfer performance. However, an electric field is known to be one of the effective methods to prevent droplet return and to address the progressive flooding issue. Therefore, in this study, an experiment is set up to investigate the effects of applied electrical voltages between two parallel copper plates on the jumping height with respect to the droplet radius and to determine the average charge of coalescing-jumping-droplets. Moreover, the gravitational force, the drag force, the inertia force and the electrostatic force as a function of the droplet radius are also discussed. The gap width of 7.5 mm and the electrical voltages of 50 V, 100 V and 150 V are experimentally investigated. Droplet motions are captured with a high-speed camera and analyzed in sequential frames. The results of the study show that the applied electrical voltage between the two plates can reduce the resistance force due to the droplet’s inertia and can increase the effects of the electrostatic force. This results in greater jumping heights and the jumping phenomenon of some bigger-sized droplets. With the same droplet radius, the greater the applied electrical voltage, the higher the coalescing droplet can jump. This work can be utilized in several applications such as self-cleaning, thermal diodes, anti-icing and condensation heat transfer enhancement.
