Project DRAC: Creating an applications-aware networkTal Lavian Ph.D.
Intelligent networking and the ability for applications to more effectively use all of the network’s capability, rather than just the transport “pipe,” have been elusive. Until now. Nortel has developed a proof-of-concept software capability — service-mediation “middleware” called the Dynamic Resource Allocation Controller (DRAC) — that runs on any Java platform and opens up the network to applications with proper credentials,making available all of the properties of a converged network, including service topology, time-of-day reservations, and interdomain connectivity options. With a more open network, applications can directly provision and invoke services, with no need for operator involvement or point-and click sessions. In its first real-world demonstrations in large research networks, DRAC is showing it can improve user satisfaction while reducing network operations and investment costs.
A Platform for Large-Scale Grid Data Service on Dynamic High-Performance Netw...Tal Lavian Ph.D.
Data intensive Grid applications often deal with multiple terabytes and even petabytes of data. For them to be effectively deployed over distances, it is crucial that Grid infrastructures learn how to best exploit high-performance networks
(such as agile optical networks). The network footprint of these Grid applications show pronounced peaks and valleys in utilization, prompting for a radical overhaul of traditional network provisioning styles such as peak-provisioning, point-and-click or operator-assisted provisioning. A Grid stack must become capable to dynamically orchestrate a complex set of variables related to application requirements, data services, and network provisioning services, all within a rapidly and continually changing environment. Presented here is a platform that addresses some of these issues. This service platform closely integrates a set of large-scale data services with those for dynamic bandwidth allocation, through a network resource middleware service, using an OGSA-compliant interface allowing direct access by external applications. Recently, this platform has been implemented as an experimental research prototype on a unique wide area optical networking testbed incorporating state-of-the-art photonic
components. The paper, which presents initial results of research conducted on this prototype, indicates that these methods have the potential to address multiple major challenges related to data intensive applications. Given the complexities of this topic, especially where scheduling is required, only selected aspects of this platform are considered in this paper.

Lambda data grid: communications architecture in support of grid computingTal Lavian Ph.D.
The practice of science experienced a number of paradigm shifts in the 20th century, including the growth of large geographically dispersed teams and the use of simulations and computational science as a third branch, complementing theory and laboratory experiments. The recent exponential growth in network capacity, brought about by the rapid development of agile optical transport, is resulting in another such shift as the 21st century progresses. Essential to this new branch of e-Science applications is the capability of transferring immense amounts of data: dozens and hundreds of TeraBytes and even PetaBytes.

An extensible, programmable, commercial-grade platform for internet service a...Tal Lavian Ph.D.
With their increasingly sophisticated applications, users promote the notion that there is more to a network (be it an intranet, or the Internet) than mere L1-3 connectivity. In what shapes a next generation service contract between users and the network, users want the network to offer services that are as ubiquitous and dependable as dial tones. Typical services include application-aware firewalls, directories, nomadic support, virtualization, load balancing, alternate site failover, etc. To fulfill this vision, a service architecture is needed. That is, an architecture wherein end-to-end services compose, on-demand, across network domains, technologies, and administration boundaries. Such an architecture requires programmable mechanisms and programmable network devices for service enabling, service negotiation, and service management. The bedrock foundation of the architecture, and also the key focus of the paper, is an open-source programmable service platform that is explicitly designed to best exploit commercial-grade network devices. The platform predicates a full separation of concerns, in that control-intensive operations are executed in software, whereas, data-intensive operations are delegated to hardware. This way, the platform is capable of performing wire-speed content filtering, and activating network services according to the state of data and control flows. The paper describes the platform and some distinguishing services realized on the platform.

Next generation applications and architectures (for example, Grids) are driving radical changes in the nature of traffic, service models, technology, and cost, creating opportunities for an advanced communications infrastructure to tackle next generation data services. To take advantage of these trends and opportunities, research communities are creating new architectures, such as the Open Grid Service Architecture (OGSA), which are being implemented in new prototype advanced infrastructures.
The DWDM-RAM project, funded by DARPA, is actively addressing the challenges of next generation applications. DWDM-RAM is an architecture for data- intensive services enabled by next generation dynamic optical networks. It develops and demonstrates a novel architecture for new data communication services, within the OGSA context, that allows for managing extremely large sets of distributed data. Novel features move network services beyond notions of the network as a managed resource, for example, by including capabilities for dynamic on-demand provisioning and advance scheduling. DWDM-RAM encapsulates optical network resources (Lambdas, lightpaths) into a Grid Service and integrates their management within the Open Grid Service Architecture. Migration to emerging standards such as WS-Resource Framework (WS-RF) should be staright forward.

Interference Revelation in Mobile Ad-hoc Networks and Confrontationirjes
In this paper, we utilize the Several interference revelation techniques proposed for mobile ad hoc
networks rely on each node passively monitoring the data forwarding by its next hop. This paper presents
quantitative evaluations of false positives and their impact on monitoring based interference revelation for ad
hoc networks. Experimental results show that, even for a simple three-node configuration, an actual ad-hoc
network suffers from high false positives; these results are validated by Markov and probabilistic models.
However, this false positive problem cannot be observed by simulating the same network using popular ad hoc
network simulators, such as ns-2, OPNET or Glomosim. To remedy this, a probabilistic noise generator model
is implemented in the Glomosim simulator. With this revised noise model, the simulated network exhibits the
aggregate false positive behavior similar to that of the experimental tested. Simulations of larger (50-node) ad
hoc networks indicate that monitoring-based interference revelation has very high false positives. These false
positives can reduce the network performance or increase the overhead. In a simple monitoring-based system
where no secondary and more accurate methods are used, the false positives impact the network performance in
two ways: reduced throughput in normal networks without attackers and inability to mitigate the effect of
attacks in networks with attackers.

Call Admission Control (CAC) with Load Balancing Approach for the WLAN NetworksIJARIIT
The cell migrations take place between the different network operators, and require the significant information exchange between the operators to handle the migratory users. The new user registration requires the pre-shared information from the user’s equipment, which signifies the user recognition before registering the new user over the network. In this thesis, the proposed model has been aimed at the development of the new call admission control mechanism with the sub-channel assignment. The very basic utilization of the proposed model is to increase the number of the users over the given cell units, which is realized by using the sub-channel assignment to the users of the network. The proposed model is aimed at solving the issue by assigning the dual sub channels over the single communication channel. Also the proposed model is aimed at handling the minimum resource users by incorporating the load balancing approach over the given network segment. The load balancing approach shares the load of the overloaded cell with the cell with lowest resource utilization. The proposed model performance has been evaluated in the various scenarios and over all of the BTS nodes. The proposed model results have been obtained in the form of the resource utilization, network load, transmission delay, consumed bandwidth and data loss. The proposed model has shown the efficiency obtained by using the proposed call admission control (CAC) along with the new load balancing mechanism. The proposed model has shown the robustness of the proposed model in handling the cell overloading factors.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

• The
technology
can
be
extended
to
offer
inter-‐metro
connecHvity.

5. Aligns with the
US Ignite Initiative
• US
Ignite,
a
501(c)3
nonprofit
organizaHon
recently
launched
by
the
White
House
Office
of
Science
and
Technology
Policy
(OSTP)
and
the
NaHonal
Science
FoundaHon
(NSF),
seeks
to
foster
the
design
and
development
of
shareable
innovaHve
applicaHons
and
digital
experiences
enabled
by
high-‐
speed
low-‐latency
networks.
These
applicaHons
will
have
the
potenHal
to
transform
how
we
access
and
experience
everything
from
weather
reports,
personalized
healthcare,
library
resources
and
transportaHon
services
while
at
home,
at
work,
or
while
mobile.
• US
Ignite
helps
maintain
US
global
leadership
in
innovaHon
by
leveraging
the
collaboraHve
capabiliHes
of
industry,
government,
and
academia.
• To
bring
these
applicaHons
to
life,
developers
leverage
the
unique
capabiliHes
of
next-‐generaHon
networks,
including
• 100
Mbps+
and
low
latency,
permidng,
for
example,
mulHple
bi-‐direcHonal
streams
of
uncompressed
video.
• Soware-‐defined
networks
(e.g.,
OpenFlow),
promising
dramaHcally-‐improved
control
over
network
rouHng
and
opHmizaHon.
• Networks
with
capabiliHes
such
as
virtual
network
“slices”
matched
to
applicaHon
requirements
and
distributed
programmable
resources
throughout
the
network.
• Integrated
wireless
networks
to
facilitate,
for
example,
sensor
networks
and
conHnuous
remote
monitoring.
• ApplicaHons
built
to
be
open,
shared,
and
extendable.
