Methods Of Scanning Email Viruses - Applying Triz To Improve Anti-Virus Programs, Umakant Mishra

Umakant Mishra

An email virus makes use of the email technology and attaches itself to an email to transfer itself from one computer to another. Some email viruses create and send new emails using the address book of the victim computer. The email viruses are a matter of concern as they can spread very fast via emails to different geographical locations.

The conventional scanners are file based and not good for scanning emails as the emails can contain different types of files as attachments. Besides they cannot detect viruses until the emails are downloaded and opened by the recipient in order to …

Implementing Virus Scanning In Computer Networks, Umakant Mishra

Umakant Mishra

Some viruses exploit the features and capabilities of computer networks to spread, operate and damage network environments. For example, the virus may copy itself to other computers in the network or may increase network activities congesting the network traffic. The conventional anti-viruses are not efficient enough to detect and control viruses in a network environment. As they are file based they cannot scan the data while being downloaded from the server.

Most of the drawbacks of conventional scanning are taken care by a firewall-based virus scanning. But this method requires high-end machines to withstand the load of centralized scanning. There …

An End To End-To-End? A Review Essay Of Barbara Van Schewick’S Internet Architecture And Innovation, Adam Candeub

Federal Communications Law Journal

Amidst much controversy, the FCC released its landmark "network neutrality" order in December 2010. This regulation prohibits Internet service providers, such as Verizon or Comcast, from discriminating in favor of traffic or content that they own or with which they are affiliated. Professor Barbara van Schewick's recently published book, Internet Architecture and Innovation, could not be timelier. Employing a variety of economic and technical arguments, van Schewick defends the type of regulation the FCC passed as necessary to preserve the Internet's potential for innovation. My central critique of Internet Architecture is its deployment of economic theories on one side of …

Dsm64: A Distributed Shared Memory System In User-Space, Stephen Alan Holsapple

Master's Theses

This paper presents DSM64: a lazy release consistent software distributed shared memory (SDSM) system built entirely in user-space. The DSM64 system is capable of executing threaded applications implemented with pthreads on a cluster of networked machines without any modifications to the target application. The DSM64 system features a centralized memory manager [1] built atop Hoard [2, 3]: a fast, scalable, and memory-efficient allocator for shared-memory multiprocessors.

In my presentation, I present a SDSM system written in C++ for Linux operating systems. I discuss a straight-forward approach to implement SDSM systems in a Linux environment using system-provided tools and concepts avail- …

Decimal Alu, Ming Zhu

College of Engineering: Graduate Celebration Programs

The decimal number system is used in many commercial applications, such as financial analysis, banking, tax calculation, currency conversion, insurance and accounting. With the explosively increasing amount the data to be proposed, computers are introduced to help deal with it. However, in digital Arithmetic Logic Unit (ALU) circuit systems, the binary number system is widely used for its simplicity and easy realization in physical layout. This project aims at constructing an ALU that contains decimal additions, subtractions and multiplications using binary coded decimal (BCD) on a binary system platform.

Dr Deogratias Harorimana

The principal objective of this paper is to review the current Tuna Fisheries Policies in the Solomon Islands with a view to proposing strategies that will maximize Job creation while at the same time address the issues that currently exist in this sector. Although the Tuna Industry’s contribution to GDP is quite significant, the Solomon Island Government (SIG) gets little or close to nothing out of it in the form of revenue and Job creation with the majority of vessels being foreign owned and fishing license fees amongst the lowest in the Pacific. SOLTAI which is partly owned by the …

Modeling Product Development As A System Design Game, C. Jason Woodard

C. Jason Woodard

A system design game is a model of a situation in which agents’ actions determine the structure of a system, which in turn affects the system’s value and the share of value that each agent may capture through bargaining or market competition. This paper describes a class of games in which agents design interdependent products, for example software programs, which may be complements or substitutes for each other. These relationships are epresented by an object called a design structure network (DSN). Depending on the modeler’s choice of allocation rules, agents may benefit from owning critical nodes in the DSN, corresponding …

Modeling Architectural Strategy Using Design Structure Networks, C. Jason Woodard

C. Jason Woodard

System architects face the formidable task of purposefully shaping an evolving space of complex designs. Their task s further complicated when they lack full control of the design process, and therefore must anticipate the behavior of other stakeholders, including the designers of component products and competing systems. This paper presents a conceptual tool called a design structure network (DSN) to help architects and design scientists reason effectively about these situations. A DSN is a graphical representation of a system’s design space. DSNs improve on existing representation schemes by providing a compact and intuitive way to express design options—the ability to …

Scheduling Medical Application Workloads On Virtualized Computing Systems, Javier Delgado

FIU Electronic Theses and Dissertations

This dissertation presents and evaluates a methodology for scheduling medical application workloads in virtualized computing environments. Such environments are being widely adopted by providers of “cloud computing” services. In the context of provisioning resources for medical applications, such environments allow users to deploy applications on distributed computing resources while keeping their data secure. Furthermore, higher level services that further abstract the infrastructure-related issues can be built on top of such infrastructures. For example, a medical imaging service can allow medical professionals to process their data in the cloud, easing them from the burden of having to deploy and manage these …
