This item is printed on demand - it takes 3-4 days longer - Neuware -In an environment of fluctuating yields due to weather uncertainties and varying market responses of farmers as a whole the importance of having correct estimates of production is of utmost importance from a public policy point of view. For making right decisions about the most sensitive area of food security and for long term planning it is desirable to estimate the key variables in advance for a reasonable planning horizon. Also the study of supply response at disaggregated level is imperative as responses may be different for different zones. Therefore, the concern of this thesis is to examine the impact different factors on the supply of agricultural commodities in different agro-ecological zones in Punjab in order to make necessary adjustments in the policy reforms. The knowledge of supply greatly helps in farm decisions in allocation of resources in right direction. It can help planners and policy makers to allocate and achieve production targets and in long term planning.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I discuss the estimation of a process capability index for three-dimensional data. Initially, I focus on the case in which the engineering tolerance associated with the measurements is a sphere. Then, I extend the discussion to the more general case in which the engineering tolerance is ellipsoidal. In both cases, I develop summary measures for repeatability and reproducibility, to be used in the context of a process capability index. In the spherical tolerance case I define summary measures, where each measure is based on the diameter of a sphere that leads to a pre-specified capture rate. As a process capability index, I propose ratios, where each ratio is the diameter of such a sphere divided by the diameter of the tolerance sphere. In the ellipsoidal tolerance case, such summary measure is based on the length of the major axes of the ellipsoid of identical shape and orientation to the tolerance ellipsoid providing a pre-specified capture rate. As a process capability index, I propose ratios, where each ratio is the major axis of such ellipsoid divided by the major axis of the tolerance ellipsoid. 92 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Facial expressions convey non verbal cues, which play an important role in interpersonal relations. Automatic recognition of human face based on facial expression can be important component of natural human-machine interface. It may also be used in behavioral science. Although human can recognize the face practically without any effort, but reliable face recognition by machine is a challenge. This book presents a new approach for recognizing the face of a person considering the expression of the same human face at different instant of time. This methodology is developed combining Eigenface method for feature extraction and k-Means clustering for identification of the human face. In experimental purpose, AT&T face database is used which contains a set of 40 people with 10 images with different facial expressions at the different illumination. Experimental results demonstrate the efficacy of the approach. This book is written such a manner that it will help researchers to work on the area of image processing and pattern recognition. It also helps graduate students to know the background and basic theories of different face recognition methods. 72 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The three topics discussed in the three chapters of this thesis are only loosely related. Strictly speaking, only Chapter 1 is about invariant theory. Namely, it is shown that the invariant theory of the orthogonal group acting on the direct sum of several copies of the standard vector representation differs drastically over fields of characteristic 2 from the well-known theory in all other characteristics. As a result, we encounter non-classical behaviour also over the ring of integers. In Chapter 2, we work over the field of complex numbers. We obtain new formulae for the irreducible characters of the classical matrix groups, more specifically, we express them as fractions of polynomials in the entries of matrix powers. Our formulae can be viewed as unexpected constructions of conjugation invariant functions of matrices. In Chapter 3, we work over the real field, and we prove inequalities for positive semi-definite matrices. Chapter 3 is the most down-to-earth part of this thesis, it ends with an application to the problem of bounding from below the norm of a product of linear functionals. 68 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book analyzes the concept of using oil tankers' free cargo space and/or segregated ballast tanks to transport freshwater on the return leg, i.e. from oil unloading port back to oil loading port - also called freshwater backhauling (FWBH). The hypothesis considered is that by shipping freshwater this way to arid, oil exporting regions one can achieve a low cost and low GHG emission water supply system.The book analyzes the concept in a holistic manner,considering technical issues, transport and infrastructure costs,environmental impacts and contractual and legal issues.Costs are estimated both on a general and scenario specific level. It is found that freshwater could be shipped by way of backhauling by oil tankers to Saudi Arabia from Japan at a cost of between 0.83 and 1.16 USD/ton, including all infrastructure except distribution systems and excluding modifications to the tankers themselves.This cost level makes FWBH to a certain degree competitive with the chief water supply technology in the Middle East, desalination.It is clear,that in many cases FWBH is the superior option compared to desalination, especially when including environmental aspects. 116 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book, synthesis of metal and metal oxide nanostructures through the novel, simple and inexpensive electrical arc discharge in liquids presented. Important functional metal and semiconductor nanostructures such as ZnO, WO3, ZrO2, TiO2, Ag and Au were successfully produced. Also Ag-codoped TiO2 nanoparticles using a combination of top down arc discharge and bottom up sol-gel methods have synthesized. XRD and XPS results indicated formation of ZnO, WO3 and ZrO2 phase. TEM images revealed cubic WO3 and rod-like as well as semi spherical ZnO nanostructures. The particle size was found to increase with an increase in the arc current. Photocatalytic activity of produced nanostructures demonstrated that by increasing UV illumination time, the maximum absorption peak and concentration of Rh. B decreases in the presence of metal oxide nanostructures. In fact, decrease of concentration for ZrO2 was found to be more pronounced than the ZnO and WO3 which was due to increased surface to volume ratio. The present method can be used for the synthesis of various kinds of nanostructures from metal to metal oxide and compound nanomaterials. 76 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is now beyond any doubt that USER AUTHENTICATION is the most critical element in the field of Information Security. To date, Text Based Password Authentication (TBPA) has shown some difficulties that users have tended to write passwords down manually or save them on hard disc. This tendency is caused by the passwords being strong and thus difficult to memorize in most cases. This has inadvertently given rise to security issues pertaining to attack. Graphical User Authentication (GUA) has two symbiotic pillars as its foundation: USABILITY & SECURITY. The macro-concept of GUA is based on the human psychological factor that is images are more readily committed to memory than would TBPA's. All GUA algorithms are made up of both usability and security aspects. This book tries to find and explain GUA algorithms from 1996 till 2010 and define the evaluation features of GUA algorithms based on standards. Finally the GUA algorithms will be evaluated by these evaluation methods. 88 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Arabic language is a difficult language to study due to the existence of two varieties within the same language; that is, its diglossic nature. Consequently, vocabulary acquisition in Arabic seems to suffer because both varieties known as standard Arabic and colloquial Arabic are acquired in different ways and are linguistically distant. Hence, the distance between the two varieties of Arabic affects vocabulary acquisition of the language. This book is based on a research study which explains the relationship between diglossia and vocabulary acquisition. This study includes two objectives. The first objective is to investigate the effect of diglossia on vocabulary acquisition of bilingual Lebanese students in Arabic. The second objective is to determine which vocabulary (Arabic vs. English) students have a preference for. The results showed a significant negative effect between diglossia and vocabulary acquisition. The students showed more confidence in using the English language over Arabic. This book would be useful to professionals in the education field, researchers, and anyone that is interested in the Arabic language. 92 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The purpose of this study is to examine Chinua Achebe's critique of both African and European cultures in his four novels: Things Fall Apart, Arrow of God, No Longer at Ease, and A Man of the People. This study utilizes strategies of close textual analysis in the context of postcolonial and cultural studies. It explores the native culture before the arrival of the white man and its contact with the alien culture. Moreover, it deals with the impact of colonial education upon the native community and upon the colonized person's identity. Colonial education creates ambivalent persons, who suffer from hybrid identity. Finally, this study explores Achebe's critique of the native culture after colonialism. The native customs and values have been turned upside down and replaced by Western material values. The loss of spiritual control over the materialistic elements leads to the spread of corruption and chaos. The study concludes that the pre-colonial Africa is more organized than the post-independence Africa, which experiences a new form of colonialism known as neo-colonialism. 88 pp. Englisch. …
