Self-adjoint (a,b)-modules and hermitian forms

In this thesis we analyse the behaviour of (a,b)-modules under the action of the duality functors. We are mostly interested in the existence of self-adjoint (a,b)-modules admitting an hermitian form, which we show is not a trivial condition: every self-adjoint regular (a,b)-module can be split into the direct sum of hermitian (a,b)-modules and (a,b)-modules admitting only an anti-hermitian form. This result leads us to the proof of existence of self-dual Jordan-Holder composition series for regular self-adjoint (a,b)-modules and we provide, following Ridha Belgrade, an alternative proof of the existence of Kyoji Saito's “higher residue pairings”.

Homological Functors of Local Cohomology Modules

Let 'a' be an ideal of a commutative Noetherian ring R and let 'X' be an arbitrary R-module. In this book, we discuss the properties of extension module Ext^s_R(N, H^t_a(X)) and torsion module Tor_R^s(N, H^t_a(X)) which present some results about cofiniteness, Bass numbers, Betti numbers and projective dimensions of local cohomology modules. Also, we study section functors of local cohomology modules which has some results about Artinian and non-Artinian local cohomology modules.

Generalization of Flat Module over Non-Commutative Ring Generalization of Flat Module over Non-Commutative Ring Новинка

Generalization of Flat Module over Non-Commutative Ring

This study enhances the study of module approximation over commutative rings to module approximation over general rings. Free, torsion free, projective, flat approximations and approximations by modules embeddable in a flat module appear in literature. In this study a slightly different concept of I-flat modules is utilized to study approximations. Covers by I-flat modules and modules embeddable in I-flat modules are thus studied in the newer set up. Also, the links between flat and I-flat covers are explored. In modern literature the terminology of approximation is some times replaced by the terminology of cover. Throughout this study it is preferred to adopt the same.
On some classes of modules and their endomorphism ring On some classes of modules and their endomorphism ring Новинка

On some classes of modules and their endomorphism ring

The first aim of this book is to generalize this result from indecomposable modules to square-free ones by showing that an injective module is square-free if and only if its endomorphism ring is quasi-duo. The second aim is to describe all maximal right (left, two-sided) ideals of the endomorphism ring of an arbitrary injective module. And the third aim is to study two classes of modules: Loewy modules with finite Loewy invariants over an arbitrary ring and max modules with finite radical invariants over a semilocal ring.

An Essay on Modular Biology

The book supports the idea that life, from its simplest forms to humans, is based in four inheritance systems: the system of genetic inheritance, the system of epigenetic inheritance, the system of behavioral inheritance and the system of symbolic inheritance. To every inheritance system mentioned above a particular memory structure corresponds. These memory structures are respectively nucleic acids, proteins, neuro-endocrine substances and neurons. The biological information is deposited in each of them and according to which a function is performed and thus, functional units or modules are formed. Inheritance systems mentioned above correspond to genetic modules, epigenetic modules, neuro-endocrine modules and cultural modules.

Maximum Power Point tracker solar charge controller ( MPPT ) Maximum Power Point tracker solar charge controller ( MPPT ) Новинка

Maximum Power Point tracker solar charge controller ( MPPT )

Maximum power point tracker frequently referred to as MPPT, is an electronic system that operates the Photovoltaic (PV) modules in a manner that allows the modules to produce all the power they are capable of. MPPT is not a mechanical tracking system that “physically moves” the modules to make them point more directly at the sun. MPPT is a fully electronic system that varies the electrical operating point of the modules so that the modules are able to deliver maximum available power which varies with environmental parameters like solar radiation, temperature and wind speed. So extracting the maximum power from the panel is very important from the system efficiency point of view. Additional power harvested from the modules is then made available as increased battery charge current . It is a h/w interface b/w the solar panel & Battery . It increases efficiency of the solar panel.
Theoretical Investigation of PV/T Using Various Backpipe Structures Theoretical Investigation of PV/T Using Various Backpipe Structures Новинка

Theoretical Investigation of PV/T Using Various Backpipe Structures

One of the most challenges in using photo voltaic (PV) systems is the low energy conversion efficiency of PV cells and, furthermore, this efficiency decreases during the operational period due to the increase of the cells temperature above a certain limit. To increase the efficiency of PV systems one way is cooling them during the operation period and these temperature losses from the PV modules can be tapped in other applications. This work investigates the efficiency of PV modules by Finite Element Methods (FEM). Comsol Multiphysics program used to simulate a PV/T system with an active cooling system conducted to cool a fixed PV modules at which an absorbed system consists of different Materials, Shapes, and Diameters of pipes welded with aluminum plate is attached underneath the PV modules to allow water flow in the backside of it.

Semipotent rings and modules Semipotent rings and modules Новинка

Semipotent rings and modules

This book is an introductory text to the theory of semipotentness of rings and modules which is introduced as a natural generalization of Von Neumann regular rings. In the study of the regular rings, one of the interesting questions is the following: In a regular ring, is every one sided ideal be regular ring?. The answer of this question is negative in general. It was proved that every one sided ideal of a regular (semipotent) ring is semipotent. R. Ware proved that, there are projective regular modules which do not have a regular endomorphism ring. It was proved that, the endomorphism ring of every regular module (in the sense of Zelmanowitz) is semipotent with zero radical Jacobson. The second part of this book is specialize to study of the total, which is first introduced by F. Kasch, and the connection between semipotentness and the total. In addition to that it studies the semipotentness of (M,N) which is introduced as a generalization of the semipotent (endomorphism) ring and the semipotent (endomorphism) ring related to (co)singular ideal. The third part specialize to study of modules which are introduced as a generalization of the regular and locally projective modules.
Exceptional representations of simple algebraic groups Exceptional representations of simple algebraic groups Новинка

Exceptional representations of simple algebraic groups

Let G be a simply connected simple algebraic group over an algebraically closed field K of positive characteristic p, with root system R and g=L(G) be its restricted Lie algebra. Let V be a finite dimensional g-module over K. For any point v in V, the isotropy subgroup of v in G and the isotropy subalgebra of v in g are defined. A restricted g-module V is called exceptional if for each v in V, its isotropy subalgebra contains a non-central element. This book presents a classification of irreducible exceptional g-modules. A necessary condition for a g-module to be exceptional is found and a complete classification of modules over groups of simple algebraic groups of exceptional type and of classical type A is obtained. For modules over groups of classical types B, C and D, the general problem is reduced to a short list of unclassified modules. The classification of exceptional modules is expected to have applications in modular invariant theory and in the classification of modular simple Lie superalgebras.
Cyclic Pure Submodules Cyclic Pure Submodules Новинка

Cyclic Pure Submodules

In abstract algebra, the concept of a module over a ring is a generalization of the notion of vector space, where instead of requiring the scalars to lie in a field, the scalars lie in arbitrary ring.The notion of purity was first introduced in abelian groups. This notion was extended to modules over principal ideal domains (PID). In 1952, Kaplansky introduced the notion of purity for modules over Dedekind domains. He has generalized most of the results in abelian groups to modules over a Dedekind domain. P.M.Cohn was first to define the purity in terms of tensor product for modules over an arbitrary ring and has shown that this notion is equivalent to one introduced for modules over a PID. Later Stenstrom has studied various notions of purity. Warfield Jr.has given projective characterization for purity and has introduced the notion of RD-purity which is same as purity in abelian groups. Hiremath has dualized the notion of purity as copurity and has made detailed investigation of copurity. In this thesis, we have made detailed study of cyclic purity and its dual cocyclic copurity.

This book describes a tool suite, VEasy, which was developed specifically for aiding the process of teaching Functional Verification. VEasy contains four main modules that perform linting, simulation, coverage collection/analysis and testcase generation, which are considered key challenges to achieve verification success. Each of those modules is commented in details throughout the chapters. All the modules are integrated and built on top of a Graphical User Interface. This framework enables the testcase automation methodology which is based on layers, where one is capable of creating complex test scenarios using drag-and-drop operations. Whenever possible examples are given using simple Verilog designs. The capabilities of the tool and its performance are also compared with some commercial and academic functional verification tools.

Teaching Moral Concepts through Teaching Modules: Teaching Moral Concepts through Teaching Modules: Новинка

Teaching Moral Concepts through Teaching Modules:

The book "Teaching Moral Concepts through Teaching Modules: A Modular Approach" has been written for the purpose how to teach moral concept. teaching moral concept is not an easy job. As students do not start acting upon moral principles just hearing the moral sermon of the teacher. They should be involved in practical activities based on moral principles. In the era of information communication technologies, we need to provide practical training to our students in moral concpets. In moral development the fbasic step is that first we think about moral situation and take decision about what is right and what is wrong. The moral behaviour comes next. There is need to train our teachers to teach through modules. It is possible only if they are provided training in how to develop module. The present book fulfills this need of teachers.
Lectures on Differential Geometry of Modules and Rings Lectures on Differential Geometry of Modules and Rings Новинка

Lectures on Differential Geometry of Modules and Rings

Differential geometry of smooth vector bundles can be formulated in algebraic terms of modules over rings of smooth functions. Generalizing this construction, one can define the differential calculus, differential operators and connections on modules over arbitrary commutative, graded commutative and non-commutative rings. For instance, this is the case of quantum theory, supergeometry and non-commutative geometry, respectively. The book aims to summarize the relevant material on this subject. Some basic applications to quantum theory are considered. The book is based on the graduate and post graduate courses of lectures given at the Department of Theoretical Physics of Moscow State University (Russia) and the Department of Mathematics and Physics of University of Camerino (Italy). It addresses to a wide audience of mathematicians, mathematical physicists and theoreticians.
Climatic Impact on the PV Modules Performance in Nigeria Climatic Impact on the PV Modules Performance in Nigeria Новинка

Climatic Impact on the PV Modules Performance in Nigeria

PV modules are tested by their manufacturers at STCs of 1000W/m2 solar irradiance and 25oC module temperature. However, the actual operating conditions of theses modules, usually vary from the STCs. In this work, climate data recorded for 8 cities of Nigeria have been used to stimulate the module temperatures and electrical outputs of 3 module types of 100W each. The results gotten were analyzed and the cities with high ambient temperature and low wind speed had high module temperature, lower Voc and efficiency, than the cities with lower ambient temperature and higher wind speed. High solar irradiation cities recorded high Isc and max power. The stimulated results were used to estimate the pv array size for a typical Nigerian home and values compared with RETScreen results.
