Ph.D. Aalto University School of Science ABSTRACT OF THE Degree programme in Computer Science and MASTER’S THESIS Engineering Author: Péter Somogyi Title: Analysis of server-smartphone application communication patterns Number of pages: 83 Date: June 15, 2014 Language: English Professorship: Data Communication Code: T-110 Software Supervisor: Professor Jukka Nurminen, Aalto University Professor Tamás Kozsik, Eötvös Loránd University Instructor: Máté Szalay-Bekő, M.Sc. Ph.D. Abstract: The spread of smartphone devices, Internet of Things technologies and the popularity of web-services require real-time and always on applications. The aim of this thesis is to identify a suitable communication technology for server and smartphone communication which fulfills the main requirements for transferring real- time data to the handheld devices. For the analysis I selected 3 popular communication technologies that can be used on mobile devices as well as from commonly used browsers. These are client polling, long polling and HTML5 WebSocket. For the assessment I developed an Android application that receives real-time sensor data from a WildFly application server using the aforementioned technologies. Industry specific requirements were selected in order to verify the usability of this communication forms. The first one covers the message size which is relevant because most smartphone users have limited data plan. -

Order #231369) • Manipulation Instructions for Rapid Switching of the Program Environment • The Intel 8080A is a complete 8-bit parallel central processing unit (CPU). It is fabricated on a single LSI chip using Intel's n-channel silicon gate MOS process. This offers the user a high performance solution to control and processing applications. The 8080A contains 6 8-bit general purpose working registers and an accumulator. The 6 general purpose registers may be addressed individually or in pairs providing both single and double precision operators. Arithmetic and logical instructions set or reset 4 testable flags. A fifth flag provides decimal arithmetic opera tion. The 8080A has an external stack feature wherein any portion of memory may be used as a last in/first out stack to store/retrieve the contents of the accumulator, flags, program counter, and all of the 6 general purpose registers. The 16-bit stack pointer controls the addressing of this external stack. This stack gives the 8080A the ability to easily handle multiple level priority interrupts by rapidly storing and restoring processor status. -

The Early Years of Academic Computing: L a Memoir by Douglas S
03 G A The Early Years of Academic Computing: L A Memoir by Douglas S. Gale E This is from a collection of reflections/memoirs concerning the early years of academic comput- ing, emphasizing the period when Cornell developed its own decentralized computing environ- ments and networking became a national strategic goal. ©2016 Henrietta Gale Initial Release: April 2016 (Increment 01) Second Release: April 2017 (Increments 02-04) Published by The Internet-First University Press Copy editor and proofreader: Dianne Ferriss The entire incremental book is openly available at http://hdl.handle.net/1813/36810 Books and Articles Collection – http://ecommons.library.cornell.edu/handle/1813/63 The Internet-First University Press – http://ecommons.library.cornell.edu/handle/1813/62 C. Memoir by Douglas S. Gale Preface and Introduction Bill Arms and Ken King have chronicled much of the early history of academic computing. Accordingly, I have tried to focus my contribution to The Early Years of Academic Computing on topics less covered by King and Arms. My contribution is organized into four chronological periods, roughly spanning the last 50 years of the 20th century, and each has an organizational theme: career transitions, the microcomputer revolution, the networking revolution, and the changing role of academic computing and networking. The theme of the first period -- career transitions -- will consider where the early practitioners of academic computing came from. Computer Science was first recognized as an academic discipline in 1962, and the early years of academic computing were led by people who had received their academic training in other disciplines. Many, if not most, came from the community of computer users and early adopters. -

Classification of Computers
Chapter-2 Classification of Computers Computers can be classified many different ways -- by size, by function, or by processing capacity. Functionality wise 4 types a) Micro computer b) Mini Computer c) Mainframe Computer d) Super Computer Microcomputers Microcomputers are connected to networks of other computers. The price of a microcomputer varies from each other depending on the capacity and features of the computer. Microcomputers make up the vast majority of computers. Single user can interact with this computer at a time. It is a small and general purpose computer. Mini Computer Mini Computer is a small and general purpose computer. It is more expensive than a micro computer. It has more storage capacity and speed. It designed to simultaneously handle the needs of multiple users. Mainframe Computer Large computers are called Mainframes. Mainframe computers process data at very high rates of speed, measured in the millions of instructions per second. They are very expensive than micro computer and mini computer. Mainframes are designed for multiple users and process vast amounts of data quickly. Examples: - Banks, insurance companies, manufacturers, mail-order companies, and airlines are typical users. Super Computers The largest computers are Super Computers. They are the most powerful, the most expensive, and the fastest. They are capable of processing trillions of instructions per second. It uses governmental agencies, such as:- Chemical analysis in laboratory Space exploration National Defense Agency National Weather Service Bio-Medical research Design of many other machines Limitations of Computer Computer cannot take over all activities simply because they are less flexible than humans. It does not hold intelligence of its own. -
From Social Welfare to Social Control: Federal War in American Cities, 1968-1988
From Social Welfare to Social Control: Federal War in American Cities, 1968-1988 Elizabeth Kai Hinton Submitted in partial fulfillment of requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2013 © 2012 Elizabeth Kai Hinton All rights reserved ABSTRACT From Social Welfare to Social Control: Federal War in American Cities, 1968-1988 Elizabeth Hinton The first historical account of federal crime control policy, “From Social Welfare to Social Control” contextualizes the mass incarceration of marginalized Americans by illuminating the process that gave rise to the modern carceral state in the decades after the Civil Rights Movement. The dissertation examines the development of the national law enforcement program during its initial two decades, from the Omnibus Crime Control and Safe Streets Act of 1968, which established the block grant system and a massive federal investment into penal and juridical agencies, to the Omnibus Anti-Drug Abuse Act of 1988, which set sentencing guidelines that ensured historic incarceration rates. During this critical period, Presidential Administrations, State Departments, and Congress refocused the domestic agenda from social programs to crime and punishment. To challenge our understanding of the liberal welfare state and the rise of modern conservatism, “From Social Welfare to Social Control” emphasizes the bipartisan dimensions of punitive policy and situates crime control as the dominant federal response to the social and demographic transformations brought about by mass protest and the decline of domestic manufacturing. The federal government’s decision to manage the material consequences of rising unemployment, subpar school systems, and poverty in American cities as they manifested through crime reinforced violence within the communities national law enforcement legislation targeted with billions of dollars in grant funds from 1968 onwards.
