...Math 202 - Assignment 6 Authors: Yusuf Goren, Miguel-Angel Manrique and Rory Laster Exercise 14.8.1. Proof. The discriminant of x4 + 1 is D = 256 = 28 . We have x4 + 1 ≡ (x + 1)4 (mod 2). Let p be an odd prime (so p D), and suppose the irreducible factors of x4 + 1 have degrees n1 , n2 , . . . , nk . By Corollary 41, the Galois group of x4 + 1 contains an element with cycle structure (n1 , n2 , . . . , nk ). Since the Galois group of x4 + 1 over Q is the Klein 4-group, in which every element has order dividing 2, it follows that each ni = 1 or 2. This gives the possibilities (1, 1, 1, 1), (1, 1, 2), (2, 2). However, D is a square and so the Galois group in contained in A4 ; in particular it contains no transpositions, so (1, 1, 2) is ruled out. This leaves the possibilities (1, 1, 1, 1), and (2, 2), which correspond to the factorization into 4 linear factors or 2 quadratic factors, respectively. Exercise 14.8.3. Proof. The polynomial f (x) = x5 + 20x + 16 is irreducible mod 3 and hence must be irreducible. The Galois group is therefore a transitive subgroup of S5 . The discriminant of f (x) is 216 56 and hence a square; therefore the Galois group is a subgroup of A5 . Modulo 7, we have factorization into irreducibles as f (x) ≡ (x + 2)(x + 3)(x3 + 2x2 + 5x + 5) (mod 7). Therefore the Galois group contains a 3 cycle. From the table on page 643, we see that the Galois group must be isomorphic to A5 . Exercise 14.8.6. Proof. By Eisenstein at 3, we see that f (x) is irreducible,...

...Chapter 1 The Accounting Information System After reading this Chapter you should understand the reasons for studying Accounting Information Systems. [pic] Video: http://www.youtube.com/watch?v=HNC1pvXwfzQ Question: Describe 5 ways these accounting systems can benefit a business. The recurring theme of this class and book is the changing role of the accountant and auditor as the trusted business advisor in the organization. The accountant no longer just prepares financial statements but is involved in decisions such as new hardware and software to purchase, strategic decisions such as mergers and new product lines, and controls to protect the information systems. Accountants and auditors need an extensive knowledge base in technology and business in order to assist in these tasks. Accounting information systems use application software that records and processes accounting transactions within functional modules such as accounts payable, accounts receivable, payroll, and trial balance. It functions as an accounting information system. It may be developed in-house by the company or organization using it, may be purchased from a third party, or may be a combination of a third-party application software package with local modifications. It varies greatly in its complexity and cost. Accounting software is typically composed of various modules, different sections dealing with particular areas of accounting. Among the most common are: Core Modules • Accounts...

...creates a general framework for implementing user requirements and solving problems identified in the analysis phase. As shown in Figure 20-1 on page 747 HC (page 637 SC), there are three main steps in conceptual design: 1. evaluating design alternatives, 2. preparing design specifications, and 3. preparing the conceptual systems design report. [pic] Evaluate Design Alternatives There are many ways to design an AIS, so accountants and others involved in systems design must continually make design decisions. [pic] The design team should identify a variety of design alternatives and evaluate each with respect to the following standards: 1) how well it meets organizational and system objectives, 2) how well it meets user needs, 3) whether it is economically feasible, and 4) what its advantages and disadvantages are. The steering committee evaluates the alternatives. Table 20-1 on page 748 HC (page 638 SC) presents examples of conceptual and physical design considerations and their corresponding design alternatives. Answers to these questions significantly designs the system in selecting from the alternatives. Prepare Design Specifications Once a design alternative has been selected, the project team develops the conceptual design specifications for the following elements: 1. Output. Because the system is designed to meet users’ information needs, output specifications must be...

...be ranged in a hierarchical order, derived from a CIM architecture (from the strategic decisions to the production constraints). Then, we present an Operational Research tool for solving each of these problems. 1 Introduction Flexible Manufacturing Systems (FMS) are nowadays installed in the mechanical industry, especially in car factories. However, the market constraints impose to always improve the production system and the whole production organization. The concepts developed by Taylor and applied at the beginning by Ford are progressively abandoned and replaced by the Just-In-Time concept and the Computer Integrated Manufacturing philosophy (CIM). One of the aims of the CIM philosophy is to provide an integrated information system which avoids the rigid separations between the different functionalities of a complete production system. With such integrated information systems, the loss of time on one hand between the customer order and the part delivery, on the other hand between the product design and its manufacture will be drastically reduced. To understand the complete production system, it is relatively easy to find in the scientific literature excellent general books explaining the different aspects of the Production and Operations Management (POM) ([1], [2], [3], [4], [5]). It is more difficult to discover a writing dedicated to use of Operational Research (OR) models and methods in the industrial context [6]. And it is quite impossible to find a book which offers...

...Chapter 1 - Accounting Information Systems: An Overview A system is a set of two or more interrelated components that interact to achieve a goal. Most systems are composed of smaller subsystems that support the larger system. For example, a college of business is a system composed of various departments, each of which is a subsystem. Moreover, the college itself is a subsystem of the university. Each subsystem is designed to achieve one or more organizational goals. Changes in subsystems cannot be made without considering the effect on other subsystems and on the system as a whole. Goal conflict occurs when a subsystem is inconsistent with the goals of another subsystem or with the system as a whole. Goal congruence occurs when a subsystem achieves its goals while contributing to the organization’s overall goal. Data are facts that are collected, recorded, stored, and processed by an information system. For example, the business needs to collect data about a sale (date, total amount), the resource sold (good or service, quantity sold, unit price), and the people who participated (customer, salesperson). Information is data that have been organized and processed to provide meaning and improve the decision-making process. However, there are limits to the amount of information the human mind can absorb and process. Information overload occurs when those limits are passed, resulting in a decline in decision-making quality and an increase in the cost of providing that information...

...GUIDE ALL'UNIVERSITA' BOCCONI A.A. 2011-2012 CORSI DI LAUREA TRIENNALI 1. Studenti immatricolati a partire dall'anno accademico 2010-2011 Il processo di riforma del sistema di istruzione universitario, avviato nel 1999 con la Dichiarazione congiunta dei Ministri europei dell'istruzione superiore intervenuti al Convegno di Bologna, ha trasformato l'organizzazione dell'Università italiana prevedendo una modifica nell'articolazione degli studi dell'area economico - aziendale dal ciclo quadriennale unico al cosiddetto sistema del 3 e 2 impostato su due cicli (undergraduate e graduate). La logica di omogeneizzazione dei percorsi di studio a livello europeo è stata quella di favorire la libera circolazione degli studenti fra le università durante il periodo della formazione e, successivamente, dei laureati nel mondo del lavoro. I due cicli di studio devono intendersi come completamente separati: al termine di ognuno è infatti prevista una prova finale, l'emissione di un diploma e la certificazione del titolo ottenuto. Completato il ciclo triennale lo studente può decidere se accedere direttamente al mondo del lavoro o se proseguire gli studi universitari con un corso di studi graduate (laurea specialistica o master universitario). Fin dalla prima attivazione dei corsi graduate dell'Università Bocconi, per l'ammissione è previsto un processo di selezione distinto da quello dei corsi undergraduate e pertanto l'ammissione ad un corso di laurea triennale non implica automaticamente...
