In this paper a Threshold based Directional Weighted Median (TDWM) Filter for Removal of Random valued Impulse Noises (RVIN) from digital and Infrared Images, has been proposed. This filter works in two phases; at first it detects the impulses, and then replaces the pixels affected with impulses by an estimated value. This filter works efficiently in suppressing impulses from both digital images and infrared images highly corrupted with random valued impulses. Extensive simulations show that proposed filter provides better results than existing filters in suppressing impulses.
本文提出了一种基于阈值的方向加权中值滤波方法,用于去除数字图像和红外图像中的随机脉冲噪声(RVIN)。这个过滤器分为两个阶段;它首先检测脉冲,然后用一个估计值替换受脉冲影响的像素。该滤波器能有效地抑制来自数字图像和红外图像的脉冲,这些图像被随机值脉冲严重损坏。大量的仿真结果表明,该滤波器在抑制脉冲方面比现有滤波器具有更好的效果。

Rough set theory is a well established tool for dealing with inconsistent data. The dependencies among the attributes, their significance, and evaluation can easily be performed using intelligent data analysis tool viz., rough set theory. The objective of this article is to modify the existing stock market predictive model based on rough set approach by A.E Hassanien et al. and to construct a data model that would generate fewer number of decision rules. Moreover the results obtained from the proposed data model are compared with well-known software tool Rough set Exploration system 2.2 popularly known as RSES 2.2. It is shown that the proposed model has a higher overall accuracy rate and generates more compact and fewer rules than RSES 2.2. Rough confusion matrix is used to evaluate the predicted classification performances. The effectiveness of this data model is demonstrated on data set consisting of daily movements of a stock traded in Kuwait Stock Exchange spanning over a period of five years.
粗糙集理论是一种成熟的处理不一致数据的工具。使用智能数据分析工具即粗糙集理论,可以很容易地进行属性之间的依赖关系、它们的重要性和评估。本文的目的是修改A.E Hassanien等人基于粗糙集方法的现有股票市场预测模型,构建一个生成较少决策规则的数据模型。并将所提出的数据模型得到的结果与知名软件工具Rough set Exploration system 2.2(简称RSES 2.2)进行了比较。结果表明,与RSES 2.2相比,该模型具有更高的整体准确率,生成的规则更紧凑、更少。使用粗糙混淆矩阵来评价预测的分类性能。该数据模型的有效性在由科威特证券交易所交易的股票的日常运动组成的数据集上得到了证明,该数据集跨越了五年的时间。

Handwritten signature is being used in various applications on daily basis. The problem arises when someone decides to imitate our signature and steal our identity. In different area these signature are verified by human being. But the outcomes depend on the ability of the person who performs this verification. Thus, there is a need for an automated system that can, with a great degree of certainty, identify the authorized person. This paper proposes a novel approach of signature verification. Firstly, the given signature is represented by a means of a graph, whose nodes and edges describe certain properties at sample points and relationship between points respectively. Then, graph matching techniques are introduced to compute the similarity of graph for the given signature with the graph information store in the database. This principle can be implemented off-line handwritten signature recognition systems. The system is compared with Global feature approach and gives satisfactory result.
手写签名在日常生活中被广泛应用。当有人决定模仿我们的签名并窃取我们的身份时,问题就出现了。在不同的地区,这些签名是由人类验证的。但结果取决于进行验证的人的能力。因此,需要一种自动化系统,它能够在很大程度上确定被授权的人。提出了一种新的签名验证方法。首先,用图的方式表示给定的签名,图中的节点和边分别描述了样本点上的某些属性和点与点之间的关系。然后,引入图匹配技术,利用数据库中存储的图信息计算给定签名的图的相似度。这个原理可以实现离线手写签名识别系统。将该方法与全局特征方法进行了比较,得到了满意的结果。

Smriti Ranjan Bhattacharya, Anupam De
Indian Urban Local Self Governments (ULSGs) are in the dire need to find out a mechanism for allocation of scare resources to fund different expenditures in the absence of proper budgetary and financial control. Grant from upper tiers should be expended as per direction of state or central governments and therefore it is required to find out how own income will be allocated. This study is an effort towards this direction along with a meaningful conclusion through a case study.
在缺乏适当的预算和财务控制的情况下,印度城市地方自治政府(ULSGs)迫切需要找到一种分配稀缺资源的机制来资助不同的支出。上级政府的拨款应该按照邦或中央政府的指示使用,因此需要弄清楚自己的收入将如何分配。本研究是朝着这个方向的努力,并通过案例研究得出有意义的结论。

This paper examines the impact of eight firm - specific determinants of corporate capital structure or financial leverage - firm size, tangibility, growth opportunities, profitability, non - debt tax shields, operating risk, liquidity and firm age - over the entire conditional distribution of leverage through the application of quantile regression methodology on a balanced panel data related to a selected sample of 76 Indian pharmaceutical companies listed on the Bombay Stock Exchange over a period of 10 years from 2002-03 to 2011-12. The coefficients of the explanatory variables are estimated at five quantiles, namely, 5th, 25th, 50th, 75th and 95th. The empirical results indicate marked non-linearities in the relationships between leverage and its firm-specific determinants with the estimated regression coefficients of the explanatory variables changing magnitudes and statistical significance accompanied by change of signs (in some cases) at different quantiles. This study, though limited to a particular industry, is primarily an attempt to affirm the existence of non-linearities in capital structure determinants of corporate firms in the Indian scenario.
本文考察了公司资本结构或财务杠杆的八个企业特定决定因素——公司规模、有形资产、增长机会、盈利能力、非债务税盾、经营风险、流动性和公司年龄-通过应用分位数回归方法,对从2002-03年至2011-12年10年间在孟买证券交易所上市的76家印度制药公司的选定样本相关的平衡面板数据进行了平衡面板数据。解释变量的系数估计在5分位数,即第5、第25、第50、第75和第95分位数。实证结果表明,杠杆与其企业特定决定因素之间存在明显的非线性关系,解释变量的估计回归系数在不同分位数上的变化幅度和统计显著性伴随着符号的变化(在某些情况下)。虽然这项研究仅限于一个特定的行业,但主要是试图确认印度情景中公司公司资本结构决定因素的非线性存在。

Decision making with geometric aggregation operators based on intuitionistic fuzzy sets 基于直觉模糊集的几何聚集算子决策
Pub Date : 2014-12-04 DOI: 10.1109/ICBIM.2014.6970940

Xu and Yager (2006) proposed some geometric aggregation operators based on intuitionistic fuzzy sets (IFS) and introduced the concept of sub-interval of membership values to define IFS. Based on the sub-interval, they defined various geometric aggregation operators such as intuitionistic fuzzy weighted geometric (IFWG) operator, intuitionistic fuzzy ordered weighted geometric (IFOWG) operator, and intuitionistic fuzzy hybrid geometric (IFHG) operator. In this paper, we propose these geometric aggregation operators (IFWG, IFOWG, and IFHG) based on IFS using the sub-interval of non-membership values. These operators can be used in an environment where the arguments are presented as intuitionistic fuzzy sets. Numerical examples are given to illustrate the operators. We also present an algorithm to show the application of the IFHG operator to multiple attribute decision making (MADM) problems based on intuitionistic fuzzy sets. Finally the algorithm has also been illustrated through a numerical example.
Xu和Yager(2006)提出了一些基于直觉模糊集(IFS)的几何聚合算子,并引入隶属度子区间的概念来定义IFS。在子区间的基础上,定义了直觉模糊加权几何算子、直觉模糊有序加权几何算子和直觉模糊混合几何算子等几何聚合算子。在本文中,我们利用非隶属值的子区间,在IFS的基础上提出了IFWG、IFOWG和IFHG这些几何聚合算子。这些运算符可用于参数以直觉模糊集的形式呈现的环境中。给出了数值算例来说明这些算子。我们还提出了一种算法来展示IFHG算子在基于直觉模糊集的多属性决策问题中的应用。最后通过一个数值算例对该算法进行了说明。

The paper presents an application of a new method - Modified Fuzzy Programming Technique(MFTP) for the Fuzzy optimal solution to the Single Objective FuzzyTransportation Problem(SOFTP) with Fuzzy parameters in terms of Triangular Fuzzy Numbers without defuzzifying the problem. Numerical illustrations are solved to show the better results and comparisons are also provided to show the same. The problem is formulated where parameters of cost objective functions, supply and demand are taken as Triangular Fuzzy Numbers. The proposed method is applied for the first time to solve the SOFTP. First, the SOFTP is converted into a Multi-Objective Transportation Problem and then solved by the MFTP.

Most of the developed countries universities have understood the advantages and usage of mobile based learning (m-learning) and have put mobile based learning into practice not only in distance education, but also in regular class room learning process. Developing countries like India, having a huge students presence and a large number of universities, institutions, though gradually shifting towards Information Communication and Technology (ICT) enabled education system, practically has no mobile based learning. Recently Government of India has understood the need and as a part of the agenda has started thinking and encouraging m-learning as tool, an addendum to ICT enabled education system. Keeping in focus on the Government of India initiatives and the need of m-learning in higher education, the paper makes feasibility analysis by making market, technical and economical analysis of m-learning in universities, institutions in India running higher education like engineering and scientific research. The feasibility analysis is added with a survey on 301 students from an Engineering institute, for their acceptance, technical and usability issues of mobile based learning. The survey results shows a positive indication, but, with many issues, to be taken care of.
大多数发达国家的大学已经认识到移动学习(m-learning)的优势和用途,不仅在远程教育中,而且在常规的课堂学习过程中都将移动学习付诸实践。像印度这样的发展中国家,拥有大量的学生和大量的大学,虽然逐渐转向信息通信和技术(ICT)支持的教育系统,但实际上没有基于移动的学习。最近,印度政府已经认识到这一需求,并作为议程的一部分,开始考虑并鼓励将移动学习作为一种工具,作为利用信息通信技术的教育系统的增编。本文关注印度政府的举措和移动学习在高等教育中的需求,通过对印度大学、工程和科研等高等教育机构的移动学习进行市场、技术和经济分析,进行可行性分析。通过对某工程学院301名学生的调查,对移动学习的接受度、技术和可用性等问题进行了可行性分析。调查结果显示出积极的迹象,但仍有许多问题需要注意。

Employees are the most important factor in the success and failure of any organization. The catering industry is a service industry that sells foods and other things to its guest therefore employees' performance plays a very important role. The hospitality industry in India is running short of good employees and facing a serious threat from other sectors also. The reasons behind this are some of the motivational factors like good remuneration, a work-life balance, better working environment and faster professional growth are providing by other service sectors. Correlation and regression analysis are used for this analysis. This study investigated the role of motivation and its components e.g. compensation, performance evaluation, appraisal, training and development and promotion practices on employee performance in the catering industry under Hospitality organization in Kolkata.
员工是任何组织成败的最重要因素。餐饮业是一个向客人出售食物和其他东西的服务行业,因此员工的绩效起着非常重要的作用。印度的酒店业缺乏优秀的员工,也面临着来自其他行业的严重威胁。这背后的原因是其他服务部门提供的一些激励因素,如良好的薪酬、工作与生活的平衡、更好的工作环境和更快的职业发展。本分析采用了相关分析和回归分析。本研究调查了动机及其组成部分,如薪酬、绩效评估、考核、培训和发展以及晋升实践对加尔各答酒店组织餐饮行业员工绩效的作用。
