Working Correspondence with Clark Boardman Callaghan (CBC) and, Subsequently, with West Group (1995 – 1998)

Correspondence with Clark Boardman Callaghan technical and editorial people following the release and success of the CD-ROM. The subjects include updating issues and whether the scope of the work should be expanded. Following the acquisition of West Publishing by Thomson the issues of switching to a different data source (Westlaw) and combination with West commentary works take center stage

`Electronic Publishing' -- Practice and Experience

Electronic Publishing -- Origination, Dissemination and Design (EP-odd) is an academic journal which publishes refereed papers in the subject area of electronic publishing. The authors of the present paper are, respectively, editor-in-chief, system software consultant and senior production manager for the journal. EP-odd's policy is that editors, authors, referees and production staff will work closely together using electronic mail. Authors are also encouraged to originate their papers using one of the approved text-processing packages together with the appropriate set of macros which enforce the layout style for the journal. This same software will then be used by the publisher in the production phase. Our experiences with these strategies are presented, and two recently developed suites of software are described: one of these makes the macro sets available over electronic mail and the other automates the flow of papers through the refereeing process. The decision to produce EP-odd in this way means that the publisher has to adopt production procedures which differ markedly from those employed for a conventional journal

A Practical Study of E-mail Communication through SMTP

Simple Mail Transfer Protocol (SMTP) is an application layer protocol for e-mail communication. It has been adopted as a standard by Internet Engineering Task Force (IETF). SMTP has set conversational and grammatical rules for exchanging messages between connected computers. It has evolved through several revisions and extensions since its formation by Jon Postel in 1981. In SMTP, the sender establishes a full-duplex transmission channel with a receiver. The receiver may be either the ultimate destination or an intermediate forwarding agent. SMTP commands are issued by the sender and are sent to the receiver, which responds to these commands through codes. Each SMTP session between the sender and the receiver consists of three phases namely: connection establishment, mail transactions and connection termination. This paper describes and illustrates the process of e-mail communication through SMTP by issuing the individual SMTP commands directly to transmit e-mail messages. It also describes individual SMTP commands and extensions with practical implementation using a Telnet client

Analyse the risks of ad hoc programming in web development and develop a metrics of appropriate tools

Today the World Wide Web has become one of the most powerful tools for business promotion and social networking. As the use of websites and web applications to promote the businesses has increased drastically over the past few years, the complexity of managing them and protecting them from security threats has become a complicated task for the organizations. On the other hand, most of the web projects are at risk and less secure due to lack of quality programming. Although there are plenty of frameworks available for free in the market to improve the quality of programming, most of the programmers use ad hoc programming rather than using frameworks which could save their time and repeated work. The research identifies the different frameworks in PHP and .NET programming, and evaluates their benefits and drawbacks in the web application development. The research aims to help web development companies to minimize the risks involved in developing large web projects and develop a metrics of appropriate frameworks to be used for the specific projects. The study examined the way web applications were developed in different software companies and the advantages of using frameworks while developing them. The findings of the results show that it was not only the experience of developers that motivated them to use frameworks. The major conclusions and recommendations drawn from this research were that the main reasons behind web developers avoiding frameworks are that they are difficult to learn and implement. Also, the motivations factors for programmers towards using frameworks were self-efficiency, habit of learning new things and awareness about the benefits of frameworks. The research recommended companies to use appropriate frameworks to protect their projects against security threats like SQL injection and RSS injectio

A VHDL-AMS Simulation Environment for an UWB Impulse Radio Transceiver

Ultra-Wide-Band (UWB) communication based on the impulse radio paradigm is becoming increasingly popular. According to the IEEE 802.15 WPAN Low Rate Alternative PHY Task Group 4a, UWB will play a major role in localization applications, due to the high time resolution of UWB signals which allow accurate indirect measurements of distance between transceivers. Key for the successful implementation of UWB transceivers is the level of integration that will be reached, for which a simulation environment that helps take appropriate design decisions is crucial. Owing to this motivation, in this paper we propose a multiresolution UWB simulation environment based on the VHDL-AMS hardware description language, along with a proper methodology which helps tackle the complexity of designing a mixed-signal UWB System-on-Chip. We applied the methodology and used the simulation environment for the specification and design of an UWB transceiver based on the energy detection principle. As a by-product, simulation results show the effectiveness of UWB in the so-called ranging application, that is the accurate evaluation of the distance between a couple of transceivers using the two-way-ranging metho

IAPSA 2 small-scale system specification

The details of a hardware implementation of a representative small scale flight critical system is described using Advanced Information Processing System (AIPS) building block components and simulated sensor/actuator interfaces. The system was used to study application performance and reliability issues during both normal and faulted operation

Interactive-engagement vs traditional methods: A six-thousand-student survey of mechanics test data for introductory physics courses

The complete report from Richard Hake's long-term study of interactive engagement (IE) techniques and their effect on the understanding of physics by non-physics majors. The study analyzed diverse student populations in high schools, colleges, and universities and used pre- and post-instruction testing to determine the gains in each group. IE techniques were shown to improve student's understanding at a significantly higher rate than traditional instruction. Additionally, these IE techniques are applicable to teaching a wide range of topics. Educational levels: Graduate or professional

New Pleading, New Discovery

Pleading in federal court has a new narrative. The old narrative was one of notice, with the goal of broad access to the civil justice system. New Pleading, after the landmark Supreme Court cases of Twombly and Iqbal, is focused on factual sufficiency, with the purpose of screening out meritless cases that otherwise might impose discovery costs on defendants. The problem with New Pleading is that factual insufficiency often is a poor proxy for meritlessness. Some plaintiffs lack sufficient factual knowledge of the elements of their claims not because the claims lack merit but because the information they need is in the hands of defendants. New Pleading thus screens out these claims even though they may have merit. This Article offers a solution to New Pleading\u27s problems of information asymmetry: New Discovery. New Discovery recognizes the need for a carefully limited presuit or predismissal discovery paradigm to provide plaintiffs the opportunity to gather the facts necessary to comply with New Pleading\u27s strictures. Drawing heavily on the experience of state procedural systems, the Article presents a normative defense of New Discovery, offers some guiding principles and tools for controlling its scope and cost, and explores how New Discovery might work both under the current discovery scheme and in the context of needed discovery reforms
