...Messages of all kinds are conveyed on a day to day basis. Graffiti for example, is one form of conveying a public message. As described by the Cambridge Dictionary, graffiti are "writings or drawings made on surfaces in public places", this kind of artwork first began to display some sort of self-expression or story. Banksy, a British street artist, conveys his messages through the same manner of powerful artwork like graffiti. Whenever a message is purposely trying to be conveyed, there must be elements included like the rhetorical triangles of ethos, pathos, logos as well as the audience, purpose, and context. Furthermore, the author of the message will also have to convey the aspect of Master Class. In respect to this particular artwork by Banksy, the message...

...AVR312: Using the USI module as a I2C slave Features • • • • C-code driver for TWI slave, with transmit and receive buffers Compatible with Philips' I2C protocol Interrupt driven, detection and transmission/reception Wake up from all sleep mode, including Power Down 8-bit Microcontrollers Application Note 1 Introduction The Two Wire serial Interface (TWI) is compatible with Philips' I2C protocol. The bus was developed to allow simple, robust and cost effective communication between integrated circuits in electronics. The strengths of the TWI bus includes the capability of addressing up to 128 devices on the same bus, arbitration, and the possibility to have multiple masters on the bus. The Universal Serial Interface (USI) module on devices such as ATmega169, ATtiny26 and ATtiny2313, has a dedicated Two-wire mode. The USI provides the basic hardware resources needed for synchronous serial communication. Combined with a minimum of control software, the USI allows higher transfer rates and uses less code space than solutions based on software only. Interrupts are included to minimize the processor load. This document describes how to use the USI for TWI slave communication. Source code for communication drivers for transmission and reception is provided. The code is complete with both data buffer handling and combined transmitter and receiver. Rev. 2560C-AVR-09/05 2 Theory This section gives a short description of the TWI and USI interfaces...

...over SSL. The server sends its own certificate, and if the server requires client authentication then the server also requests for the client's certificate. 3. The client uses the information sent by the server to authenticate the server. If the server cannot be authenticated, then the user is warned of the problem that an encrypted and authenticated connection cannot be established with the server. If authentication is successful, the client proceeds to step 4. 4. Client, using all data generated in the handshake thus far (with the cooperation of the server, depending on the cipher being used and SSL version number and cipher settings) creates the pre-master secret for the session, with the help of server's public key it encrypt it (obtained from the server's certificate received in step 2), and then it sends the encrypted pre-master secret to the...

...at Sun Microsystems Lab on wireless security. 1.Introduction With the rapid growth in the wireless mobile communication technology, small devices like PDAs, laptops are able to communicate with the fixed wired network while in motion. Because of its flexibility and provision of providing ubiquitous infrastructure, the need to provide security increases to a great degree. As wireless communication takes place mainly through the radio signals rather than wires, it is easier to intercept or eavesdrop on the communication channels. Therefore, it is important to provide security from all these threats. There are different kinds of issues within security like confidentiality, integrity, availability, legitimacy, and accountability that needs to be individually taken care off. One of the key issues of these being, confidentiality and authentication, where the user must be protected from unauthorized eavesdropping. The goal of authentication protocol is to check the identity of other users or network centers before providing access to the confidential information on the users side. When designing any security protocol, there are...

...into Hornsby’s land and was shot. Burden did not want Hornsby to get away with the murder of Old Drum, therefore Burden sued Hornsby, in the court case of Burden v. Hornsby. However, throughout the trial, Hornsby was seen as not guilty and in favor of the jury. Until Vest (Burden’s attorney) addressed his closing remarks of “Eulogy of the Dog,” moved the jury to be complimentary with Burden, and earned him well-deserved justice for Old Drum. Through the tragic death of Old Drum, provoked Vest to addresses to his audience of the jury and dog-lovers, whose pathos, tone and imagery underscore the theme of insufficient loyalty of dogs in a world of selfish men, in order to demonstrate the significance of the relationship between dogs and their masters. George Graham Vest was a leading orator and debater at his time. He was a part of the Confederate Congress; after the Civil War ended, he practiced law and was elected to the Senate as a Democrat, where he served for 24 years. His shift of political parties indicated his change of beliefs in political policies, implementing the leniency of his actions to represent Burden in the occurrence of his dog. He developed liberal views on animal rights, exemplifying that he believed the compensation of fees was necessary due to a murder of an animal. Just like, in the case of the shooting of Old Drum, it made him concerned on the immorality of the event. Vest felt obligated to win justice for the death of Old Drum. About four years after the Civil...

...Spiritual Laws is an intellectual method of evangelism, which, as it’s title suggests, identifies four spiritual laws that direct an individual’s relationship with God. It was created by Dr. Bill Bright, founder of Campus Crusade for Christ, in 1952. The four laws, as sited on CampusCrusade.com, are: (1) God loves you and offers a wonderful plan for your life. (2) Man is sinful and separated from God. Therefore, he cannot know and experience God’s love and plan for his life. (3) Jesus Christ is God’s only provision for man’s sin. Through Him you can know and experience God’s love and plan for your life. (4) We must individually receive Jesus Christ as Savior and Lord; then we can know and experience God’s love and plan for our lives. An advantage of this method is that it begins with positive note, “God loves you and offers a wonderful plan for your life,” which may cause non-Christians to be more receptive to the message. Due to the fall and sin, mankind is at variance with God (Ephesians 2:13-16) and there may be a tendency to reject a message concerning God without ever hearing the message. However, starting with such a positive introduction may cause an individual to “lower his guards” so he can hear the Gospel. Another advantage of this approach is that it can be easily communicated in print form and makes for a useful tract, especially considering the positive opening law. One disadvantage of this method is an increased likelihood that individuals who come to Christ as...

...Ibrahim Sec.: 4 BN: 11 Table of Content Introduction 2 What is Bluetooth technology? 3 Bluetooth technology differs from other radio technologies: 3 Bluetooth Architecture: 4 1. Piconet 4 2. Scatternet 5 Bluetooth Frame Format: 6 Bluetooth Security 7 List of applications 8 Introduction The aim of this report is to explain the Bluetooth technology. Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994[1] .it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 25,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must make a device meet Bluetooth SIG standards to market it as a Bluetooth device. Network of patents apply to the technology, which are licensed to individual qualifying devices. The name "Bluetooth" comes from the 10th century Danish King Harald Blåtand or Harold Bluetooth in English. King Blåtand helped unite warring factions in parts...

...ENSEMBLE Case Study: Partners HealthCare System Partners HealthCare uses InterSystems Ensemble to integrate internal and external EMRs Partners HealthCare System Inc., based in Boston, Massachusetts, is an innovative integrated healthcare network that includes multiple major hospitals with more than 7,000 physicians attending to four million outpatient visits and 160,000 admissions per year. Partners’ institutions, including Massachusetts General Hospital and Brigham and Women’s Hospital, consistently rank among the best hospitals in the United States, according to U.S. News and World Report. To maintain its leadership status, Partners establishes enterprise-wide, CEO-supported corporate initiatives under the banner of “HighPerformance Medicine.” “Ensemble has given us tremendous flexibility with data transformations, and made us much more agile in delivering on this type of integration.” Steve Flammini, CTO One of these initiatives includes electronic medical record (EMR) adoption by all community physician practices in the Partners system. To achieve this goal, Partners offers these physicians full, Webbased access to its internal EMR. But first, Partners must rapidly create interfaces (programs that handle data translation and transmission between systems) to the community physicians’ practice management and scheduling systems, and integrate that data into its EMR. The initiative also gives participating physicians access to more than three...
