This document discusses methods for estimating costs for new product development. It describes developing cost estimates to build a business plan. There are two elements of a costing system - a cost accumulation system to track actual costs, and cost objectives like products that costs are attributed to. Direct costs like materials can be directly attributed to products, while indirect costs like overhead must be attributed to products through "cost drivers" like number of components or production time required. Accounting for all costs is important to determine a product's profitability.
This document discusses pulse modulation techniques in communications. It begins by reviewing continuous-wave modulation techniques studied previously, such as amplitude modulation and angle modulation. It then previews that pulse modulation will be studied next, including analog pulse modulation where a pulse feature varies continuously with the message, and digital pulse modulation using a sequence of coded pulses. The document provides explanations and equations regarding sampling of continuous-time signals, the sampling theorem, and recovery of the original analog signal from its samples. It also introduces pulse amplitude modulation (PAM) using natural and flat-top sampling, as well as pulse duration modulation (PDM) and pulse position modulation (PPM).
This document provides a high-level overview of operating systems and computer hardware concepts. It defines an operating system as software that manages computer hardware resources and provides common services for computer programs. It describes the role of the operating system, its structure, and the services it provides such as process management, memory management, security, and I/O management. It also provides a brief overview of basic computer hardware components like the CPU, memory, I/O devices, buses, and disks, and concepts like memory hierarchy, caching, interrupts, and virtual memory.
El resumen analiza los ingresos de ventas por regiones en el primer trimestre de 2011, mostrando los ingresos de enero, febrero y marzo, así como el promedio para cada región. La región Este obtuvo el promedio más bajo de S/ 3,016 mientras que la región Oeste obtuvo el promedio más alto de S/ 7,321. El total de ingresos para el primer trimestre fue de S/ 21,009.67.
The document provides an overview of probability theory and random variables including:
1) It defines probability as a measure of the chance of obtaining a particular outcome from an event. Common properties of probability such as mutually exclusive events and conditional probability are also covered.
2) Random variables are introduced as rules that assign real numbers to possible outcomes of an experiment. Both discrete and continuous random variables are defined.
3) Key concepts related to random variables are summarized including the cumulative distribution function, probability density function, expected value, variance, and common distributions like the uniform, binomial, and Gaussian distributions.
4) Finally, random processes are defined as sets of random variables indexed by time, with properties like the mean
This document provides an overview of marketing tools that can be used during the electrical engineering design process. It discusses primary tools like surveys, focus groups, and interviews to understand customer needs and requirements. It also covers secondary market research tools to analyze industry trends, competitors, and potential customer demographics. The document emphasizes organizing customer feedback and prioritizing requirements to guide the design process. It also addresses estimating product price and sales volume.
1. The document discusses system calls from the user's perspective, providing a high-level overview of common system call categories like process management, file I/O, and directory management.
2. It explains that system calls provide a controlled entry point for applications to make requests to the operating system kernel to perform privileged operations.
3. Examples of system calls on different platforms like Linux, Windows, and MIPS are provided to illustrate the concept.
Standards are important for both designers and customers. Designers must be aware of all relevant standards for the product and locations it will be used. Standards cover safety, quality, interchangeability and can be mandatory by law or contract. They provide guidelines for areas like performance, dimensions and best practices to facilitate design. Identifying applicable standards is an essential early task for designers.
