Live Migration of Virtual Machines

Before we describe the investigation process, we need to define the basic and fundamental concepts. There are few agreed upon definitions in the area of digital forensic research, so we will clearly state the definitions we are using, even the most basic ones. Digital data are data represented in a numerical form. With modern computers, it is common for the data to be internally represented in a binary encoding, but this is not a requirement. A digital object is a discrete collection of digital data, such as a file, a hard disk sector, a network packet, a memory page, or a process....

Why (Special Agent) Johnny (Still) Can’t Encrypt: A Security Analysis of the APCO Project 25 Two-Way Radio System

In addition to its numerical representation, digital data has a physical representation. For example, the bits in a hard disk are magnetic impulses on platters that can be read with analog sensors. Network wires contain electric signals that represent network packets and keyboard cables contain electric signals that represent which keys were pressed. A computer converts the electric signals to a digital representation. Digital photography and video are a digital representation of the light associated with physical objects. Digital data can be stored on many mediums and each has different properties that determine how long the data will reside. For example, data will reside on a keyboard...

City of Houston Parade and Street Functions

Digital objects have characteristics, or unique features, based on their creator and function. For example, the characteristics of a hard disk sector will be different when it is used to store the contents of an ASCII text document versus a JPEG image. We can use the characteristics to identify the data. The state of an object is the value of its characteristics. If a letter were changed in an ASCII text document, then the object corresponding to the file would have a new state. Similarly, the state of a running computer process changes every time data is written to its memory....

Rare-event Simulation Techniques: An Introduction and Recent Advances

The web in recent years has experienced an explosion in the number of devices users employ to access services. A single user may access a certain service using multiple devices. Most services allow clients to access the service through a broker. The client is then forced to interact with the service via this broker throughout the duration that it is using the service. If the broker fails, the client is denied servicing till such time that the failed broker recovers. In the event that this service is running on a fixed set of brokers the client, since it knows about this set of brokers, could then...

An Analysis of In-flight Passenger Injuries and Medical Conditions

A truly distributed service would allow a client to use services by connecting to a broker nearest to the client’s geographical location. By having such local broker, a client does not have to re-connect all the way back to the broker that it was last attached to. If the client is not satisfied with the response times that it experiences or if the broker that it has connected to fails, the client could very well choose to connect to some other local broker. Concentration of clients from a specific location accessing a remote broker, leads to very poor bandwidth utilization and affects latencies associated with other...

EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH (CERN)

Clients just specify the type of events that they are interested in, and the content that the event should at least contain. Clients do not need to maintain an active presence during the time these interesting events are taking place. Once it registers an interest it should be able to recover the missed event from any of the broker nodes in the system. Removing the restriction of clients reconnecting back to the same broker that it was last attached to and the departure from the time-bound failure recovery model, leads to a situation where brokers could be dynamically instantiated based on the concentration of clients...

FIS ALPINE WORLD SKI CHAMPIONSHIPS 2013 Schladming (AUT)

The system we are considering needs to support communications for 109 devices. The users using these devices would be interested in peer-to-peer (P2P) style of communication, business- to-business (B2B) interactions or a be part of a system comprising of agents where discoveries are initiated for services from any of these devices. Finally, some of these devices could also be used as part of a computation. The devices are thus part of a complex distributed system. Communication in the system is through events, which are encapsulated within messages. Events form the basis of our design and are the most fundamental units that entities need to communicate with each...

Solar Decathlon 2002: The Event in Review

We believe that it is interesting to study the system and software architecture of environments which integrate the evolving ideas of computational grids, distributed objects, web services, peer-to-peer networks and message oriented middleware. Such peer-to-peer (P2P) Grids should seamlessly integrate users to themselves and to resources which are also linked to each other. We can abstract such environments as a distributed system of “clients” which consist either of “users” or “resources” or proxies thereto. These clients must be linked together in a flexible fault tolerant efficient high performance fashion. In this paper, we study the messaging or event system – termed GES or the Grid Event Service...

A synthesis of atmospheric mercury depletion event chemistry linking atmosphere, snow and water

Messaging systems based on queuing include products such as Microsoft’s MSMQ [28]and IBM’s MQSeries [29]. The queuing model with their store-and-forward mechanisms come into play where the sender of the message expects someone to handle the message while imposing asynchronous communication and guaranteed delivery constraints. A widely used standard in messaging is the Message Passing Interface Standard (MPI) [21]. MPI is designed for high performance on both massively parallel machines and workstation clusters. Messaging systems based on the classical remote procedure calls include CORBA [35], Java RMI [32] and DCOM [19]. In publish/subscribe systems the routing of messages from the publisher to the subscriber is within the purview...

AN BILLE FÁ CHORPARÁID NA HÉIREANNACH UM RÉITEACH BAINC, 2013 IRISH BANK RESOLUTION CORPORATION BILL 2013

We have built a “production” system and an advanced research prototype. The production system uses the commercial Java Message Service (SonicMQ) and has been used very successfully to build a synchronous collaboration environment applied to distance education. The publish/subscribe mechanism is powerful but this comes at some performance cost and so it is important that it satisfies the reasonably stringent constraints of synchronous collaboration. We are not advocating replacing all messaging with such a mechanism – this would be quite inappropriate for linking high performance devices such as nodes of a parallel machine linked today by messaging systems like MPI or PVM. Rather we have recommended using a...

Synchronization and Linearity An Algebra for Discrete Event Systems

Here we study the architecture and characteristics of the broker network. We are using a particular internal structure for the events (defined in XML but currently implemented as a Java object). We assume a sophisticated matching of publishers and subscribers defined as general topic objects (defined by an XML Schema that we have designed). However these are not the central issues to be discussed here. Our study should be useful whether events are defined and transported in Java/RMI or XML/SOAP or other mechanisms; it does not depend on the details of matching publishers and subscribers. Rather, we are interested in the capabilities needed in any implementation a...

Probabilistic Event Structures and Domains

Clients in the system specify an interest in the type of events that they are interested in. Some examples of interests specified by clients could be sports events or events sent to a certain discussion group. It is the system, which computes the clients that should receive a certain event. A particular event may thus be consumed by zero or more clients registered with the system. Events have explicit or implicit information pertaining to the clients which are interested in the event. In the former case we say that the destination list is internal to the event, while in the latter case the destination list is...

Regular Trace Event Structures

Events are continuously generated and consumed by clients within the system. Clients have intermittent connection semantics. Clients can be present in the system for a certain duration and be disconnected later on. Clients reconnect at a later time and receive events, which they were supposed to receive in their past incarnations as well as events that they are supposed to receive during their present incarnation. Clients issue/create events while in disconnected mode, these events would be held in a local queue to be released to the system during a reconnect. Associated with every client is its profile, which keeps track of information pertinent to the client. This includes...

Safety Assessment of Roundup ReadyCorn Event NK603

Models are an initial useful starting point and can assist in a more structured and ordered approach to the planning of events. There is no one model which fits all. It is for the event organizer to perhaps select and engage with a model he / she finds useful, and one which they can understand, share with their colleagues / stakeholders and add to or detract from. These models are not set in stone, they need to be reviewed, but they may well assist as a reference point. As a visual representation of the key areas of the event planning...

Common Terminology Criteria for Adverse Events v3.0 (CTCAE)

Planning is the most important part of running a successful event, and this means starting well in advance. The best way to approach planning is to develop a detailed management plan, which includes a timetable of what needs to be done and when. Crucial elements of the planning for the event, such as fundraising, booking performers and advertising need to happen well in advance of the date of your event so a timeline schedule is essential. Developing an Event Plan is critical to ensure your events success. The information provided in this document is designed to...

Introduction to Discrete-Event Simulation and the SimPy Language

In this section you should provide a general overview of your event and be as specific as possible about the activities you are proposing to conduct at the event. When selecting the dates for your event it is a good idea to check whether there are any other events already planned to avoid clashes in events. The timing of your event is also important to consider. Try not to plan your event during known quite periods when many people are out of town. Consider planning your event during the peak season to increase your...

Building Brands through Event Sponsorships: Providing On-Site Audiences with a Vivid Brand Experience

However keen you are, it is highly unlikely that you can organise an event on your own - you need a group. Groups often form around the desire to run a festival or event with the celebration of a theme, art form or sport in mind. This usually starts off being an informal grouping but as soon as the group starts to handle money then a formal statement of roles and responsibilities and decision-making becomes necessary. People volunteer for committee work for a wide variety of reasons but primarily they become involved with an organisation or an event and...

If so, the development of a traffic management plan, application to your local government authority, local Police and/or Main Roads Department, approval and advertising may be essential well in advance of your event - at least three months prior to the event. Check with your local government authority for the requirements in your town. On lodgment of the information, Council officers will inspect the area for the proposed temporary street closure and advise the applicant if it is practical and safe to do so for the purpose of conducting the event. All costs...

Event Management Best Practice Manual

Many special events are held on private property, with leadership shared among the venue owner/ private security and the local police and ire departments. Even when one law enforcement agency clearly has the lead and provides most of the resources—a July 4th celebration in a city park, for example—assistance from other law enforcement agencies may be needed (e.g., sherif’s oice for prisoner transport, county police for standby tactical support). Inter-agency Agreement. In multiple agency situations, a simple, straightforward memorandum of understanding (MOU) or agreement (MOA) should be signed.
