Colonnelli, De Gasperis Mattia. "Le azioni correlate.Tracking Stocks." Doctoral thesis, Università degli studi di Trieste, 2010. http://hdl.handle.net/10077/3667.
Повний текст джерелаIl lavoro ha ad oggetto l’istituto giuridico delle azioni correlate o di settore (già noto e diffuso in ordinamenti stranieri con il nome tracking stocks e tracking shares), introdotto nell’ordinamento giuridico italiano dalla recente riforma di diritto societario al fine di rendere le forme di finanziamento della società per azioni più efficienti, flessibili e maggiormente adatte alle esigenze degli investitori e dei mercati di capitali. Tale strumento di partecipazione azionaria offre l’opportunità di un investimento remunerato secondo la produttività di uno specifico settore dell’attività esercitata dalla società emittente. Ai sensi del novellato art. 2350, comma 2, c.c., le azioni correlate sono, infatti, “azioni fornite di diritti patrimoniali correlati ai risultati dell’attività sociale in un determinato settore”. Lo studio si apre con l’analisi delle ragioni economico-finanziarie sottostanti l’emissione di tracking stocks, soffermandosi sul diversification discount, la corporate governance, l’asimmetria informativa, le operazioni straordinarie di ristrutturazione aziendale, i particolari equilibri nell’ambito di compagini complesse, l’incentivazione ai managers, la predisposizione di poison pills in caso di scalate ostili. Il precedente storico dell’istituto risale al 1984 quando General Motors al fine di acquisire Electronic Data System attribuì agli azionisti di quest’ultima azioni correlate al core business della medesima società acquisita. La prima operazione europea di ammissione alla quotazione di azioni correlate è avvenuta in Francia nel 2000, anno in cui Alcatel S.A. collocava sul premier marchè azioni correlate all’attività della società controllata Alcatel Optronics. In Italia, le tre società chiuse AIMAG S.p.A. (2006), ATAF S.p.A. (2005) e Friulia S.p.A. (2005) e l’investment company quotata Cape Live S.p.A. (2007) hanno emesso azioni correlate. Vengono approfonditi, tra l’altro, l’ambito di applicabilità dell’istituto, con particolare riguardo alla definizione di settore, alle divisional tracking stocks ed alle subsidiary tracking stocks, e la correlazione dei diritti patrimoniali ai risultati di un settore specifico di attività sociale esercitata dall’emittente (correlazione in senso forte, o close tracking, e correlazione in senso debole, o loose tracking), quale elemento minimo e caratterizzante tale categoria azionaria. Si conclude che sul piano strutturale e funzionale il risultato del settore rappresenta il parametro quantitativo, il criterio, relativo o assoluto, fisso o variabile, per il calcolo della parte di risultato di esercizio di spettanza delle azioni correlate. Sono analizzati, poi, i diritti patrimoniali tipici delle azioni correlate, quali il diritto agli utili, la partecipazione alle perdite ed il diritto alla quota di liquidazione, e i diritti amministrativi, quali il diritto di voto in assemblea generale ed in assemblea speciale, anche nel contesto dell’autonomia statutaria. Il lavoro prosegue con la trattazione del tema dell’accertamento del risultato di settore e delle modalità di rendicontazione da inserirsi all’interno dello statuto. Si argomenta che il risultato di settore non può considerarsi concetto giuridico e/o contabile predefinito e non rappresenta il contenuto del diritto patrimoniale dell’azionista, ma solo un parametro di commisurazione dello stesso, in funzione del criterio di correlazione prescelto. Viene trattato, inoltre, il diritto di conversione delle azioni correlate in azioni ordinarie come meccanismo di exit, funzionale a disciplinare la sorte delle azioni correlate al verificarsi di predeterminati eventi o condizioni. Si esaminano le clausole di conversione ricorrenti nella prassi internazionale, di cui si verifica la compatibilità con l'ordinamento italiano. Infine, vengono identificate le nuove criticità di corporate governance cui le azioni correlate danno luogo, come ad esempio le nuove conflittualità orizzontali tra i soci relative all’allocazione di risorse, delle opportunità d’affari (corporate opportunities), delle spese e dei costi comuni. In tale contesto si forniscono alcuni standards di condotta che gli amministratori di società multi settoriali devono seguire, onde evitare di incorrere in responsabilità verso la società, i soci o i creditori sociali. In tale contesto, si parte dalla constatazione di carattere economico per cui l’impresa multi settoriale è accostabile al fenomeno del gruppo di società ovvero dell’imprenditore-persona fisica o comunque soggetto che abbia rilevanti interessi economici in altre imprese, individuali o collettive. E’ interesse comune a tutti gli azionisti sia che la società mantenga un sano equilibrio economico e finanziario sia che la società venga gestita, nel suo complesso, in modo efficiente. Nel caso in cui la società è insolvente perdono tutti i soci. Una gestione economicamente efficiente conduce alla massimizzazione del valore aggregato delle azioni, cui corrisponde la massimizzazione del valore di ciascuna categoria di azioni, cuore della teoria del c.d. shareholder value. In tale prospettiva l'attenzione si sposta necessariamente sulle modalità gestionali. Infatti, tale interesse comune può essere perseguito esclusivamente attraverso una continua e costante azione perequativa da parte degli amministratori volta ad armonizzare ed ottimizzare il funzionamento particolare di ciascun settore con quello degli altri.

Повний текст джерелаThis qualitative case study examined leaders’ shared data use, a process of translating data into action (Bernhardt, 2013). Understanding data use is considered conceptually by attending to the assistance relationships shared between central office leaders and principals in the context of turnaround. Such relationships are marked by occasions during which members share expertise by modeling practices; the modeling informs how systems, structures and subsequent practices are introduced and even reinforced for newer members. I focused my analysis on four manifestations of data use: data’s influence on adjusting leadership practice, data’s ability to inform instruction, data use’s benefits from technological advancement, and the intentional promotion of resilience. Data collection included document review as well as interviews with central office leaders and principals. Findings evidenced the nature of both central office leaders’ and principals’ data use as well as revealed a remarkable degree of commonality in the language and practices these leaders shared. The results of this study indicated that assistance relationships are a functioning element of leadership in the turnaround context. This study supported the research that leaders’ shared practice of data use benefits student growth and achievement in line with state-determined assessment and accountability targets. Recommendations include additional research into Lawrence Public Schools’ data use to further inform a blueprint for comprehensive district-wide reform as well as the development of exit criteria from receivership

Повний текст джерелаThe variety of situations faced by actors of the business concerning their field, and the importance of the amount of money involved, is considered as a mind moving element particularly for specialists in financial and legal matters. Enthusiasm is also rooted in the financial markets which tend to require greater transparency from groups, including financial visibility that is often reduced. Such a requirement is highly recommended in the definition of tracking stock. Emerged across the Atlantic in the early 80s, they have benefited, with the advent of the new economy, a noticeable income of interest and have increased since the early '90s until now through a large number of issuances on the U.S. financial market. The issuance of tracking stock, apart from its hybrid nature, contains a certain measure of restructuring rather special that completes the basis of studies already made on the subject of capital restructuring. This research also aims to show how to introduce tracking stock on the French financial market, and more particularly to expand the choice of forms of restructuring that will be presented to companies in hope to seek new funding sources, to obtain new ways of acquisition and achieve a fundamental objective which is the creation of value. Therefore, the issuing of tracking stock will have to compete with other forms of restructuring (spin-off, equity carve-out). Thus, we present the factors that companies should deem when choosing the restructuring proposed

Повний текст джерелаSjälvkörande bilar har lett till flera intressanta forskningsområden som kombinerar manga olika discipliner. En utmaning är att ge fordonet en sorts ¨ögon. Genom att använda ytterligare sensorer och kombinera data frän samtliga så kan man detektera hinder i fordonets väg. Detta kan naturligtvis användas för att förbättra fordonets planerade rutt och därmed också minska klimatpåverkan. Här används två sammankopplade Velodyne laserstrålsensorer för att undersöka detta Närmare, men det går också att utöka antalet sensorer ytterligare. Sammanlänkningen av sensorer är mycket känslig och kräver därför exakta koordinater, vilket inte alltid kan garanteras. Därför utreds istället om en sensor baserad på Dempster Shaferteorin kan användas för att hantera fel och osäkerheter. Denna används dock inte i testfordonet. Baserat på en sammanvägd kartbild över upptagna och fria områden (occupancy grid mapping) kan objekt och hinder i rörelse följas för att uppskatta fordonets hastighet utan att metoder för objekt- eller banidentifiering behöver användas. Experiment har utförts på verklig data. Dessutom används simulerade mätningar där en sann grundreferens används. Algoritmen som används för occupancy-kartan använder sig av central- och grafik-processorenheter, vilket ger oss möjlighet att jämföra två metoder och finna den bäst fungerande metoden för olika applikationer.

Повний текст джерелаAdvanced driver assistance systems (ADAS) help drivers to perform complex driving tasks and to avoid or mitigate dangerous situations. The vehicle senses the external world using sensors and then builds and updates an internal model of the environment configuration. Vehicle perception consists of establishing the spatial and temporal relationships between the vehicle and the static and moving obstacles in the environment. Vehicle perception is composed of two main tasks: simultaneous localization and mapping (SLAM) deals with modelling static parts; and detection and tracking moving objects (DATMO) is responsible for modelling moving parts in the environment. In order to perform a good reasoning and control, the system has to correctly model the surrounding environment. The accurate detection and classification of moving objects is a critical aspect of a moving object tracking system. Therefore, many sensors are part of a common intelligent vehicle system. Classification of moving objects is needed to determine the possible behaviour of the objects surrounding the vehicle, and it is usually performed at tracking level. Knowledge about the class of moving objects at detection level can help improve their tracking. Most of the current perception solutions consider classification information only as aggregate information for the final perception output. Also, management of incomplete information is an important requirement for perception systems. Incomplete information can be originated from sensor-related reasons, such as calibration issues and hardware malfunctions; or from scene perturbations, like occlusions, weather issues and object shifting. It is important to manage these situations by taking them into account in the perception process. The main contributions in this dissertation focus on the DATMO stage of the perception problem. Precisely, we believe that including the object's class as a key element of the object's representation and managing the uncertainty from multiple sensors detections, we can improve the results of the perception task, i.e., a more reliable list of moving objects of interest represented by their dynamic state and appearance information. Therefore, we address the problems of sensor data association, and sensor fusion for object detection, classification, and tracking at different levels within the DATMO stage. Although we focus on a set of three main sensors: radar, lidar, and camera, we propose a modifiable architecture to include other type or number of sensors. First, we define a composite object representation to include class information as a part of the object state from early stages to the final output of the perception task. Second, we propose, implement, and compare two different perception architectures to solve the DATMO problem according to the level where object association, fusion, and classification information is included and performed. Our data fusion approaches are based on the evidential framework, which is used to manage and include the uncertainty from sensor detections and object classifications. Third, we propose an evidential data association approach to establish a relationship between two sources of evidence from object detections. We observe how the class information improves the final result of the DATMO component. Fourth, we integrate the proposed fusion approaches as a part of a real-time vehicle application. This integration has been performed in a real vehicle demonstrator from the interactIVe European project. Finally, we analysed and experimentally evaluated the performance of the proposed methods. We compared our evidential fusion approaches against each other and against a state-of-the-art method using real data from different driving scenarios. These comparisons focused on the detection, classification and tracking of different moving objects: pedestrian, bike, car and truck

Повний текст джерелаThe tracking system is part of a telemetry ground station being developed for the UK Ministry of Defence. The design objective is a self-contained transportable system for field use in a vehicle or workshop environment, so that the system components are required to be man portable. Comprehensive facilities are required for the reception, display and analysis of telemetry data from a remote 1430-1450MHz airborne source at ranges of up to 205km. Since tracking over water is a prime requirement the system must accommodate severe multipath fading. A detailed analysis of the link budget indicates that there is a major conflict between cost, portability, antenna size and the receiver complexity required to achieve a satisfactory performance margin. A baseline system is analysed using a four foot antenna. Methods for improving the performance are then considered including polarisation, frequency and space diversity coupled with alternative antenna types and configurations. The optimum solution utilises two six foot diameter shaped beam single axis antennas of unique design in conjunction with a receiving system which economically combines the elements of polarisation, frequency and space diversity.

Повний текст джерелаNas últimas décadas tem-se investigado a existência (ou não) de uma superioridade do desempenho de fundos geridos ativamente face aos passivos, i.e., avalia-se quão valiosa é a gestão ativa. Dadas as divergentes conclusões encontradas na literatura financeira, não se encontra um consenso do valor da gestão ativa, continuando esta temática a se apresentar como atual e pertinente em Finanças. Porém, na maioria dos estudos avalia-se o desempenho dos fundos independentemente de serem verdadeiramente ativos, o que pode estar a ?camuflar? o real desempenho dos fundos ativos. O presente estudo ultrapassa essa situação, uma vez que efetua a avaliação do desempenho dos fundos em função dos diferentes estilos de gestão ativa. Para tal, segue-se a metodologia de Cremers & Petajisto (2009) e utiliza-se três modelos de avaliação de desempenho (CAPM, Fama-French, 1992, 1993 e Carhart, 1997). O estudo incide numa amostra de fundos de ações portugueses, centrado nas categorias Nacionais, União Europeia e Internacionais, entre Janeiro de 2005 a Dezembro de 2011, analisando o período como um todo e dois subperíodos (2005-2007 e 2008-2011). Conclui-se que a gestão ativa, em média, não adiciona valor de forma significativa, independentemente dos estilos ativos utilizados pelos gestores portugueses - pelo contrário, em períodos de instabilidade financeira, em média, destruiu valor e de forma significativa.
In the last decades it has investigated the existence (or not) of a superior performance of actively managed funds compared to passive funds, i.e., evaluates how valuable is the active management. Given the divergent conclusions in the financial literature, is not found a consensus about the value of active management, continuing this thematic to present itself as current and pertinent in Finance. However, in most studies evaluate the performance of the funds regardless of whether they are truly active, which can "mask" the real performance of the active funds. The present study overcomes this situation, since it makes the evaluation of the performance of funds according to the different styles of active management. To do so, it follows the methodology of Cremers & Petajisto (2009) and uses three models of performance evaluation (CAPM, Fama-French, 1992, 1993 and Carhart, 1997). This study uses a sample of Portuguese equity fund, focused on National, European Union and International categories, from January 2005 to December 2011, looking at the period as a whole and two sub-periods (2005-2007 and 2008-2011). We conclude that active management, on average, not significantly add value, regardless of the active styles used by Portuguese managers - moreover, during periods of financial instability, on average, destroyed value in a significant way.

The few-cycle femtosecond laser pulse has proved itself to be a powerful tool for controlling the electron dynamics inside atoms and molecules. By applying such few-cycle pulses as a driving field, single isolated attosecond pulses can be produced through the high-order harmonic generation process, which provide a novel tool for capturing the real time electron motion. The first part of the thesis is devoted to the state of the art few-cycle near infrared (NIR) laser pulse development, which includes absolute phase control (carrier-envelope phase stabilization), amplitude control (power stabilization), and relative phase control (pulse compression and shaping). Then the double optical gating (DOG) method for generating single attosecond pulses and the attosecond streaking experiment for characterizing such pulses are presented. Various experimental limitations in the attosecond streaking measurement are illustrated through simulation. Finally by using the single attosecond pulses generated by DOG, an attosecond transient absorption experiment is performed to study the autoionization process of argon. When the delay between a few-cycle NIR pulse and a single attosecond XUV pulse is scanned, the Fano resonance shapes of the argon autoionizing states are modified by the NIR pulse, which shows the direct observation and control of electron-electron correlation in the temporal domain.

Повний текст джерелаIntelligent systems are more and more present in our society, like the systems of surveillance and civilian or military sites protection. Their purpose is to detect intruders and present the alarms or threats to a distant operator. In our work, we are interested in such systems with the aim to better handle the quality of information presented to the operator in terms of reliability and precision. We focus on the image modality and we have to handle detections that are both uncertain and imprecise in order to present reliable objects to the operator.To specify our problem, we consider the following constraints. The first one is that the system is modular; one subpart of the system is the detection of fragments corresponding potentially to objects. Our second constraint is then to use only information derived from the geometry of these fragmentary detections: spatial location in the image and size of the detections. Then, a threat is supposed all the more important as the detections have an important size and are temporally persistent.The chosen formal framework is the belief functions theory that allows modeling imprecise and uncertain data. The contributions of this thesis deal with the objects representation in terms of imprecise and uncertain location of the objects and object filtering.The pertinent representation of information is a key point for estimation problems and decision making. A representation is good when simple and efficient criteria for the resolution of sub problems can be derived. The representation proposed has allowed us to derive, in a simple and rigorous way, an association criterion between new detections (fragments) and objects under construction. We remind that this association is a key step for several problems with unlabelled data that extends our contribution beyond of the considered application.Data filtering is used in many methods and algorithms to robustify the results using the expected data redundancy versus the noise inconsistency. Then, we formulated our problem in terms of dynamic estimation of a discernment frame including the 'true hypotheses'. This frame is dynamically estimated taking into account the new data (or observations) that allow us to detect two main types of errors, namely the duplication of some hypotheses (objects in our application) and the presence of false alarms (due to noise or false detections in our case).Finally, we show the possibility of coupling our sub-functions dealing with object construction and their filtering with a tracking process using higher level information such as classical tracking algorithm in image processing.Keywords: belief functions theory, data association, filtering

Повний текст джерелаThis thesis deals with multi-objet tracking and classification problem. It was shown that belieffunctions allow the results of classical Bayesian methods to be improved. In particular, a recentapproach dedicated to a single object classification which is extended to multi-object framework. Itwas shown that detected observations to known objects assignment is a fundamental issue in multiobjecttracking and classification solutions. New assignment solutions based on belief functionsare proposed in this thesis, they are shown to be more robust than the other credal solutions fromrecent literature. Finally, the issue of multi-sensor classification that requires a second phase ofassignment is addressed. In the latter case, two different multi-sensor architectures are proposed, aso-called centralized one and another said distributed. Many comparisons illustrate the importanceof this work, in both situations of constant and changing objects classes

Повний текст джерелаThis thesis presents the joint use of the theory of evidence and multiple hypothesis tracking for modeling and managing a system for monitoring multiple cameras in a motorway. The tracking is based on the re-identification of objects (vehicles) on the basis of visuals and times informations. A realization of these concepts results in the design and implementation of a software architecture for multiple agents management of multiple camera tracking system. After presenting the state of the art on the frameworks of uncertainty management and that on information fusion for the matching, and the multi-agent systems, our contribution in this work is on two or three levels. The first was an adaptation of the decision phase of the transferable belief model to incorporate the use of multi-hypotheses tracking as a tool of ambiguity survey in case of indecision in matching situation. The second contribution was a proposition of agent-based software architecture for management of a multiple cameras tracking system. We have proposed the global system modeling as well as agents and their interactions modeling using a personal analysis method but nevertheless inspired by modelisation languages and tolls such as Agent UML, MaSE and others, because there is not yet a standard and normalized tool on the subject. Our third contribution was to begin an implementation of our agent-based software architecture using JADE (Java Agent Development Framework). Some experiment and discussions are presented at the end to lead to our conclusions and perspectives

Повний текст джерелаJoint attention is critical for social learning activities such as parent-child shared book reading. However, there is a potential disassociation of attention when the adult reads texts while the child looks at pictures. I hypothesize that the lack of joint attention limits children's opportunity to learn print-related skills. The current study tests the hypothesis with interventions that enhance real-time joint attention. Eye movements of parents and children were simultaneously tracked when they read books together on computer screens. I also provided real-time feedback to the parent regarding where the child was looking, and vice versa. Changes of dyads' reading behaviors before and after the joint attention intervention were measured from both eye movements and video records. Baseline data showed little joint attention in parent-child shared book reading. The real-time attention feedback significantly increased the joint attention and children's print-related learning. These findings supported my hypothesis that engaging in effective joint attention is critical for children to acquire knowledge and skills during shared reading and other collaborative learning activities.

The proportion of ETF investment in the domestic investment has been increasing year by year and A-Shares ETF has become one of the best ways for people to invest in China.ETF is generally evaluated based on the extent of tracking error. In this context, this study takes the daily data (from 2013 to 2015) of A-Shares ETF issued for a full year in Taiwan Stock Exchange Market as study object and explores its extent of tracking error and related influencing factors via the Vertical and Horizontal Regression Model. The study aims to help the investors to have an understanding of the tracking error of A-Shares ETF which can be used as future references for the selection of ETFinvestment. The empirical study findings can be concluded as follows: 1) the tracking error of the index return of the study object and the replication object is very small and close to 0 under the Significance Level of 1% which shows an excellent tracking performance; 2) there is a significant negative correlation between the market value size and tracking error, and a significant positive correlation between the market volatility and tracking error, while the impact of trading volume on the tracking error is not significant; 3) the Crash of A-Shares in 2014 indeed has a significant impact on the tracking error.

The P-V curve of the photovoltaic array has several local peaks when the module receives different solar irradiation, thus maximum power point tracking (MPPT) becomes difficult and complex. Several traditional methods often used in PV systems, such as perturb and observe (P&O) and hill climbing (HC), have advantages of effectivity and easy implementation. However, they cannot ensure the PV system work at the global maximum power points (GMPP’s) under partial shaded conditions (PSC). Some global maximum power point tracking (GMPPT) algorithms have been proposed, including particle swarm optimization (PSO), genetic algorithm (GA), and simulated annealing (SA), etc. They can differentiate the global maximum power point (GMPP) from the local maximum power points (LMPP’s) and, thereby operating at GMPP’s for the PV system even under PSC. However, it takes time to complete the tracking and the oscillations causes great power loss. A novel GMPPT algorithm for PV systems under PSC is proposed to determine the location of GMPP by calculating the predictive power values of all LMPP’s. Then, an improved P&O is used in the neighborhood area of the GMPP to approach the real GMPP of the PV modules. Finally, simulation and experimental results are provided to confirm the effectiveness of the proposed algorithm.

In the past, the research found that the investment targets in the defined contribution plan had the characteristic of low tracking error. In recent years, the investment market start following the factor investing strategy. And some investors start using the factor investing strategy in the practical. Funds can be used tracking error and active share to sort to four categories of funds. In these four categories, the factor bets and concentrated stock picks kinds of funds have the characteristic of factor investing. As a result, this research use these two kinds of funds to be the research object. And the purpose is to analyze weather the factor bets and concentrated stock picks kinds of funds have the high probability to be put in the 401(K) menu. This research collect the investment targets in the 401(K) menu and the CRSP fund data from 2013 to 2015. The result show that the factor bets and concentrated stock picks kinds of funds have the high probability to be put in the 401(K) menu.

This thesis studies the maximum power point tracking (MPPT) methods under partially shaded conditions for a stand-alone PV array system. The I-V and P-V curves of a PV array are first addressed. Then the rules for judging partially shaded conditions are presented and integrated into three MPPT methods. These methods are tested in off-line and real-time simulation environments as well as in an experimental platform, and their advantages and disadvantages are further analyzed. Matlab/Simulink/SimPowerSystems and RT-LAB real-time simulator are respectively used to build the off-line and real-time simulation models and the MPPT controller for partially shaded conditions. The experimental platform, SPT-2C produced by Jubilee Technology Co., Ltd., is used to conduct experimental tests on MPPT methods presented in this thesis. Based on the simulation results and experimental tests, MPPT methods integrated with judging rules for partially shaded conditions can track the maximum power point better than those with no judging rules, elevating the usage efficiency of PV arrays.

The sample of this paper includes the equity mutual funds in Taiwan from 2011 to 2015. It is very interesting to observe how the active share, tracking error, industry concentration index and other characteristics, such as fund age, turnover rate and size, affect the performance of funds in Taiwan. We implement the three methods of benchmark-adjusted returns, Jensen’s alpha or Carhart’s four factors adjusted alpha as measurement of fund performance. Empirical results indicate that active share is positively correlated with the benchmark-adjusted return. Industry concentration index and tracking error are both negatively correlated with the benchmark-adjusted return and these are all economically significant. We demonstrate that funds with lower tracking error and higher active share significantly outperform the benchmark. From an investor’s point of view, funds in Taiwan with higher active share and lower tracking error can outperform their benchmark 2.13% per year, net of fees and expenses.

In recent years, because environmental pollution and fossil energy will be run out soon, renewable energies are becoming the focus of the development worldwide. Among them, solar energy is the most attractive. The advantages of the solar energy are quiet, clean and inexhaustible. This thesis aims to study and implement a photovoltaic power supply system with three-stage energy management and maximum power point tracking (MPPT) capability under partially shaded conditions. The three-stage energy management can increase the utilization of solar panels, and raise system stability. A modified P&O MPPT method is also realized to overcome the problems due to solar shading effect. The operating principles and design considerations of the studied photovoltaic system are analyzed and discussed in details. A 2-kW laboratory prototype was implemented and tested. The experimental results are shown to verify the feasibility of the proposed scheme.
