The value "social responsibility" as a motivating factor for adolescents' readiness to participate in different types of political actions, and its socialization in parent and peer contexts.
Venue: Journal of adolescence
Year: 2012

Based on a sample of tetrads (N 839) including 16 year old adolescents, their mothers, fathers, and same sex friends, it was analyzed in which way the value social responsibility is related to adolescents' readiness for different types of political participation. Results showed that social responsibility was positively linked to readiness for participation in legal protest actions. No relationships with readiness for participation in federal elections or with readiness for participation in illegal protest actions occurred, and a negative relationship with readiness for participation in political violent actions was found. In a second step, the socialization of the value social responsibility in the parents and peer context was the focus. Value similarities between adolescents, their parents and friends, as well as other contextual factors were considered. Multiple regression analyses revealed differential effects for male and female adolescents. In male adolescents, authoritative parenting and political discussions with parents were positively linked to social responsibility. Furthermore, peer group membership had a negative impact. For female adolescents, significant value similarities with their parents, especially with their mothers, occurred. Value similarities with their friend were found in both gender groups, but appeared to be higher in the female group. Also, in both gender groups, a positive parent child relationship quality was linked to higher social responsibility. In sum, findings show that parents as well as peer contextual factors were contributing to the adolescents' value acquisition.
A Bidirectional Wireless Power Transfer for Electric Vehicle Charging in V2G System
Venue: 2019 International Conference on Electrical, Communication, and Computer Engineering (ICECCE)
Year: 2019

Wireless Power Transfer is a innovative technology in which power is transferred without physical contact. As technical knowledge is proceeding, the most of wired technology is also converting into wireless technology through different techniques.  Vehicles and plug in hybrids may be fresh and feasible but it does not enough if it is forgetting to plug in power source the night before.  Vehicle will automatically charge when it will park in the special parking space where transmitter circuit has already been developed, when an electric vehicle park on that place, charging will start automatically. A preceding review of few methods for wireless charging discover that Inductively Coupled Power Transfer System (ICPT) is a advantageous method for wireless charging of EVs(Electric Vehicles) This paper presents a Bidirectional IPT(Inductively Coupled Power Transfer) system which is appropriate for Vehicle to Grid (V2G) systems. For EV charging A bidirectional WPT is a stable dynamic and effective system. Wireless power techniques falls into two categories, non radiative and radiative. This research follows the non radiative field using magnetic inductive coupling between coils of wire. In this project mutual inductance technique is used for wireless charging for transferring voltage (12 V) for charging of that battery at a considerable distance of 30 cm between two coils. This paper will also enhance the feasibility, reliability and efficiency of the system.
Mapping of Chlorophyll and SPAD Distribution in Pepper Leaves During Leaf Senescence Using Visible and Near Infrared Hyperspectral Imaging
Year: 2016

Hyperspectral imaging covering the visible and near infrared region (420 1000 nm) was used to determine the spatial distribution of chlorophyll and SPAD (soil and plant analyzer development) in pepper leaves during leaf senescence. Hyperspectral images of pepper leaves from three positions (upper, middle, and lower) of the plant were acquired, and their corresponding chlorophyll a, b, (a+b) and SPAD values were measured using chemical analysis and a SPAD meter, respectively. Spectral reflectance values of the samples were then extracted from the hyperspectral images based on a leaf mask using image segmentation. Chlorophyll a, b, (a+b) and SPAD in leaves from the upper, middle, and lower positions were analyzed by one way analysis of variance (ANOVA) Microstructure images of pepper leaves from the upper and lower positions are shown to illustrate the chlorophyll changes in mesophyll cells. Effective wavelengths (EWs) carrying masses of valuable information were then selected by the regression coefficients (RCs) of partial least square regression (PLSR) models. As a result, five wavelengths (503, 551, 690, 717, and 770 nm) were selected as EWs for chlorophyll a, b, and (a+b) prediction, and ten wavelengths (517, 536, 545, 555, 584, 603, 610, 648, 699, and 728 nm) were selected for SPAD prediction. After that, PLSR predictive models were established using full spectra and the selected EWs. PLSR models established by EWs with coefficients of correlation for prediction (R p of 0.779, 0.743, 0.770, and 0.907 were considered optimal models for predicting chlorophyll a, b, (a+b) and SPAD, respectively. Finally, these optimal models were used to estimate the chlorophyll a, b, (a+b) and SPAD of each pixel within pepper leaf images for generating spatial distribution maps. The results indicated that hyperspectral imaging combined with chemometric analysis could determine chlorophyll and SPAD values in pepper leaves during leaf senescence, which provides a reference for monitoring plant growth.
Tibetan primary curriculum and its role in nation building
Year: 2008

This study looks at how primary education plays a central role in cultural reproduction in the Tibet Autonomous Region (TAR) The paper compares primary level Tibetan language textbooks from different periods to explore the process by which shifting political trends are reflected in the curriculum. It looks at how Tibetan identity is recreated, at different historical moments, through selective rendering of elements of Tibetan culture to reposition it within the Chinese national context. It argues that, in contrast to Central China where the curriculum has seen explicit depoliticization in recent years, and a move towards teaching personal morality and global awareness, the Tibetan primary curriculum has seen renewed emphasis on narrow political ideology.
A Multi purpose Group Signature for Vehicular Network Security
Venue: 2014 17th International Conference on Network Based Information Systems
Year: 2014

This paper adapts a new group signature (GS) scheme to the specific needs of a vehicular ad hoc network (VANET) We modify the Groth GS in order to meet a restricted, but arguably sufficient set of privacy properties. Note that Groth GS is secure in the dynamic group signature model of Bellare, Shi, and Zhang (BSZ) without relying on random oracle Model (ROM) Although some authentication schemes using GS are proposed for VANET, none of them satisfy all the desirable security and privacy properties. Either they follow GSs that rely on ROM, or unable to satisfy potential VANET application requirements. In particular, link management which allows any designated entities (e.g. RSUs in VANET) to link messages, whether they are coming from the same vehicle or a certain group of vehicles, without evealing their identities. Besides that opening soundness property prevents malicious accusations by the opener against some honest member of the group. By using this property, we propose a new secure application framework for value added service providers (VSPs) in VANET. Meanwhile, a real world VANET deployment must provide a mean to revoke system privileges from fraudulent vehicles like the traditional Public Key infrastructure (PKI) However, in order to achieve the aforementioned security properties together in VANET, we propose a new GS model where link ability, sound opening and revocability properties are assembled in a single scheme. The novelty of our proposal stems from extending the Groth GS by relaxing strong privacy properties to a scheme with a lightly lesser privacy in order to fit an existing VANET application requirements. In addition, we partially minimize the Groth GS scheme to expedite efficiency.
Herd Behaviour and Gold Investment: A Perceptual Study of Retail Investors
Year: 2013

Needs, Benefits, Fund Allocation Patterns and Resources may vary among investors but the motive is to earn beneficial level of return. The level of return may vary but an investor expects some added advantage over the blocked money. Specifically in Asia and the Middle East, gold investments and gold jewelry are regarded as financial or semi financial assets. Consumers have become aware of price movements and very sensitive to them. Unlike paper currency, coins or other assets, gold has maintained its value throughout the ages. People see gold as a way to pass on and preserve their wealth from one generation to the next. The perceptions of an investor differ with respect to alternative investment avenues, assets and segments present in the market. This study includes 183 respondents from different cities of Punjab. This paper is an attempt to study the factors influencing purchase behavior of retail investors towards gold with the help of Factor Analysis.
Global exponential stability of primal dual gradient flow dynamics based on the proximal augmented Lagrangian: A Lyapunov based approach
Venue: 2020 59th IEEE Conference on Decision and Control (CDC)
Year: 2020

For a class of nonsmooth composite optimization problems with linear equality constraints, we utilize a Lyapunov based approach to establish the global exponential stability of the primal dual gradient flow dynamics based on the proximal augmented Lagrangian. The result holds when the differentiable part of the objective function is strongly convex with a Lipschitz continuous gradient; the non differentiable part is proper, lower semi continuous, and convex; and the matrix in the linear constraint is full row rank. Our quadratic Lyapunov function generalizes recent result from strongly convex problems with either affine equality or inequality constraints to a broader class of composite optimization problems with nonsmooth regularizers and it provides a worst case lower bound of the exponential decay rate. Finally, we use computational experiments to demonstrate that our convergence rate estimate is less conservative than the existing alternatives.

Towards More Possibilities: Motion Planning and Control for Hybrid Locomotion of Wheeled Legged Robots
Venue: IEEE Robotics and Automation Letters
Year: 2020

This letter proposed a control framework to tackle the hybrid locomotion problem of wheeled legged robots. It comes as a hierarchical structure with three layers: hybrid foot placement planning, Centre of Mass (CoM) trajectory optimization and whole body control. General mathematical representation of foot movement is developed to analyze different motion modes and decide hybrid foot placements. Gait graph widely used in legged locomotion is extended to better describe the hybrid movement by adding extra foot velocity information. Thereafter, model predictive control is introduced to optimize the CoM trajectory based on the planned foot placements considering terrain height changing. The desired trajectories together with other kinematic and dynamic constraints are fed into a whole body controller to produce joint commands. In the end, the feasibility of the proposed approach is demonstrated by the simulation and experiments of hybrid locomotion running on our wheeled quadrupedal robot Pholus.
Examining the use of instructional video clips for teaching macroeconomics
Venue: Comput. Educ.
Year: 2020

Information and communication technologies (ICTs) have been integrated in teaching activities to develop new learning environments. Within ICTs, the use of multimedia, such as instructional videos, has attracted significant academic attention. Nevertheless, the use of these technologies in teaching economics has generally lagged behind other disciplines. This paper adds empirical evidence to show the effectiveness of the use of instructional videos in the field of economics. Firstly, videos illustrating dynamic graphical representations of macroeconomic processes have been developed and used in the class of one student group at the University of Seville (Spain) as complementary teaching materials in the macroeconomics curriculum. Secondly, the effectiveness of these videos has been tested by carrying out an inferential analysis on experimental and control groups. Potentially significant variables such as gender, prior knowledge and ability levels of students have been considered in the analysis. Additionally, probit and multinomial probabilistic regressions have been estimated in order to assess the impact of these materials on the probability of achieving higher test scores. The findings confirm the superiority of using instructional video clips to achieve higher test scores.
Comparative metabolic and transcriptional analysis of a doubled diploid and its diploid citrus rootstock (C. junos cv. Ziyang xiangcheng) suggests its potential value for stress resistance improvement
Venue: BMC Plant Biology
Year: 2015

BackgroundPolyploidy has often been considered to confer plants a better adaptation to environmental stresses. Tetraploid citrus rootstocks are expected to have stronger stress tolerance than diploid. Plenty of doubled diploid citrus plants were exploited from diploid species for citrus rootstock improvement. However, limited metabolic and molecular information related to tetraploidization is currently available at a systemic biological level. This study aimed to evaluate the occurrence and extent of metabolic and transcriptional changes induced by tetraploidization in Ziyang xiangcheng (Citrus junos Sieb. ex Tanaka) which is a special citrus germplasm native to China and widely used as an iron deficiency tolerant citrus rootstock.ResultsDoubled diploid Ziyang xiangcheng has typical morphological and anatomical features such as shorter plant height, larger and thicker leaves, bigger stomata and lower stomatal density, compared to its diploid parent. GC MS (Gas chromatography coupled to mass spectrometry) analysis revealed that tetraploidization has an activation effect on the accumulation of primary metabolites in leaves; many stress related metabolites such as sucrose, proline and g aminobutyric acid (GABA) was remarkably up regulated in doubled diploid. However, LC QTOF MS (Liquid chromatography quadrupole time of flight mass spectrometry) analysis demonstrated that tetraploidization has an inhibition effect on the accumulation of secondary metabolites in leaves; all the 33 flavones were down regulated while all the 6 flavanones were up regulated in 4x. By RNA seq analysis, only 212 genes (0.8% of detected genes) are found significantly differentially expressed between 2x and 4x leaves. Notably, those genes were highly related to stress response functions, including responses to salt stress, water and abscisic acid. Interestingly, the transcriptional divergence could not explain the metabolic changes, probably due to post transcriptional regulation.ConclusionTaken together, tetraploidization induced considerable changes in leaf primary and secondary metabolite accumulation in Ziyang xiangcheng. However, the effect of tetraploidization on transcriptome is limited. Compared to diploid, higher expression level of stress related genes and higher content of stress related metabolites in doubled diploid could be beneficial for its stress tolerance.

Comparative study between PI and FUZZY logic controller in vector controlled five phase PMSG based variable speed wind turbine
Venue: 2018 IEEE 12th International Conference on Compatibility, Power Electronics and Power Engineering (CPE POWERENG 2018)
Year: 2018

This paper presents a fuzzy logic controller (FLC) to control a five phase permanent magnet synchronous generator based wind turbine during wind speed variations. With the advent of the field oriented control, it is possible to make the five phase PMSG operate like a DC machine in high performance applications. The PI Controller is preferred in many cases as a speed controller, since it offers a fixed gain and integral time constant, but the performance can be affected by parameters variation, such as wind speed changing. Also, the conventional controller makes more torque ripple. To avoid this trouble, FUZZY logic controller can be used to improve the studied control. In this simulation, there is two loops of control, the first is the outer loop named speed control loop, the second is an inner loop which is known as the current loop. The efficiency of the proposed FLC is simulated and compared to a conventional PI by using MATLAB/Simulink environment, to confirm the superiority of the Fuzzy logic, and its possibility to enhance the control performance, under parameters variation.
Urdu compound Character Recognition using feed forward neural networks
Venue: 2009 2nd IEEE International Conference on Computer Science and Information Technology
Year: 2009

Urdu compound Character Recognition is a scarcely developed area and requires robust techniques to develop as Urdu being a family of Arabic script is cursive, right to left in nature and characters change their shapes and sizes when they are placed at initial, middle or at the end of a word. The developed system consists of two main modules segmentation and classification. In the segmentation phase pixels strength is measured to detect words in a sentence and joints of characters in a compound/connected word for segmentation. In the next phase these segmented characters are feeded to a trained Neural Network for classification and recognition, where Feed Forward Neural Network is trained on 56 different classes of characters each having 100 samples. The main purpose of the system is to test the algorithm developed for segmentation of compound characters. The prototype of the system has been developed in Matlab, currently achieves 70% accuracy on the average
