ABSTRACT
Microscopes are capable of producing vast amounts of data, and when used in automated laboratories both the number and size of images present many challenges for storing, categorizing, analyzing, annotating, and transforming the data into actionable information that can used for decision making; either by humans or machines. In this presentation I will describe the informatics system we have established at the Department of Pharmaceutical Biosciences at Uppsala University, which consists of computational hardware (CPUs, GPUs, storage), middleware (Kubernetes), imaging database (OMERO), and workflow system (Pachyderm) to perform online prioritization of new data, as well as the continuous analytics system to automate the process from captured images to continuously updated and deployed AI models. The AI methodologies include Deep Learning models trained on image data, and conventional machine learning models trained on features extracted from images or chemical structures. Due to the microservice architecture the system is scalable and can be expanded using hybrid-architectures with cloud computing resources. The informatics system serves a robotized cell profiling setup with incubators, liquid handling and high-content microscopy. The lab is quite young and is targeting applications primarily in drug screening and toxicity assessment, with the aim to improve research using AI and intelligent design of experiments.

The seminar discussed research into the function of LPIN1 in the adrenal cortex. The presenter aimed to characterize LPIN1's function and how protein kinase A (PKA) regulates the enzyme diacylglycerol kinase (DGK). ACTH stimulates cortisol secretion through a signaling pathway involving cAMP, PKA, DGK, and other factors. LPIN1 is believed to convert phosphatidic acid (PA) into diacylglycerol (DAG) to reduce the activity of steroidogenic factor 1 (SF1) and thus influence cortisol production. The research sought to better understand LPIN1's role in this process.

New Realm of Adult Learning Comprised by B. Mosby bdmosby08
The document discusses three approaches to adult learning: embodied or somatic learning, spiritual learning, and narrative learning. Somatic learning involves using the senses and relating information through the body. Spiritual learning focuses on discipline, commitment, and reflecting on thoughts and ideals. Narrative learning uses storytelling and self-reflection to make connections and build relationships that reinforce learning. Together, these three approaches - somatic, spiritual, and narrative - provide multi-faceted experiences that engage the body, spirit, and imagination, creating a solid foundation for continual adult learning.

This seminar discussed Alan Turing and his work to help solve David Hilbert's Entscheidungsproblem. Turing proposed using machines to incorporate basic math in an attempt to settle Hilbert's problem of finding an algorithm that determines if mathematical statements are true or false. Turing invented the Turing machine, a finite program that uses symbols on tape according to rules. He concluded that Hilbert's problem was impossible to solve since the halting problem of determining if a program finishes or runs forever cannot be decided.

DEH-DoSv6: A defendable security model against IPv6 extension headers denial ...journalBEEI
With the rapid depletion of IPv4 protocol in these recent years, the IETF introduced IPv6 as a solution to address the exhaustion, however, as a new protocol exists, new characteristics have been introduced and new threats have been discovered. Extension Headers are the new characteristics of IPv6 that have an emerging and re-emerging security threats that is needed to be taken into consideration during the full migration to the IPv6 network. This study revealed that up to this moment, the popular vendors are still vulnerable and doesn’t have any default protection to deal with extension headers’ Denial of Service Attack (DoS). Also, this study leads to the development of new security model which creates a new solution to address the emerging threats of IPv6 extension headers’ Denial of Service Attack. Moreover, the results of this study show that our proposed security model is more effective in terms of neutralizing the unwanted traffic causing evasion attack by filtering, rate-limiting and discarding the malformed packets of prohibited extension headers’ payload versus the traditional router protection.
Imperative Induced Innovation - Patrick W. Dowd, Ph. Dscoopnewsgroup
This document discusses the need for the NSA to improve its security posture and operational effectiveness through induced innovation. It argues that legacy technologies are no longer sufficient given the NSA's responsibilities. The document proposes moving to a new model consisting of an OpenStack-based utility cloud, a Hadoop-based data cloud, and a distributed storage cloud. This new model would reduce complexity, improve security, increase operational agility and efficiency, and lower costs compared to the traditional "enclave" model. The document outlines NSA's experience developing and deploying this new cloud environment since 2007 to address its growing technical needs.
This document discusses network softwarization and the role of open source. It begins by defining network softwarization as the trend toward more programmable, software-defined networks achieved through SDN and NFV. It then discusses how open source has played a role in networking, particularly through projects that enable network softwarization like OpenDaylight, OpenStack, and OPNFV. The document concludes by discussing some experiences with open source networking projects at UNICAMP like RouteFlow, libfluid, and Mininet-WiFi, which aim to advance the state of SDN and network programmability through open collaboration.

An Ad-hoc Smart Gateway Platform for the Web of Things (IEEE iThings 2013 Bes...Darren Carlson
The Web of Things (WoT) aims to extend the Web into the physical world by promoting the adoption of Web protocols by situated services and smart objects (ambient artifacts). However, real-world ambient artifacts often adopt proprietary and/or non-Web protocols, making them invisible to Web search engines and inaccessible to conventional Web agents. Smart Gateways have been proposed as a way to “Web-enable” proprietary ambient artifacts through intermediary proxy nodes; however, the requisite infrastructure is difficult to deploy at Web scale. To address such challenges, we are developing Ambient Dynamix (Dynamix): a plug-and-play context framework for mobile devices, which enables Web agents to interoperate with non-Web ambient artifacts – directly from the browser. In this paper, we describe how Dynamix can be used to transform the user’s device into an ad-hoc Smart Gateway in-situ, enabling Web applications (in the device’s browser) to seamlessly interact with non-Web ambient artifacts in the physical environment. We describe an operational prototype implementation, which enables Web apps to discover and control nearby UPnP and AirPlay media devices uniformly. We also present a performance evaluation that indicates the prototype imposes low processing and memory overhead, and is suitable for deployment on many commodity mobile devices.

Big Data, Beyond the Data Center
Increasingly the next scientific discoveries and the next industrial innovative breakthroughs will depend on the capacity to extract knowledge and sense from gigantic amount of information. Examples vary from processing data provided by scientific instruments such as the CERN’s LHC; collecting data from large-scale sensor networks; grabbing, indexing and nearly instantaneously mining and searching the Web; building and traversing the billion-edges social network graphs; anticipating market and customer trends through multiple channels of information. Collecting information from various sources, recognizing patterns and distilling insights constitutes what is called the Big Data challenge. However, As the volume of data grows exponentially, the management of these data becomes more complex in proportion. A key challenge is to handle the complexity of data management on Hybrid distributed infrastructures, i.e assemblage of Cloud, Grid or Desktop Grids. In this talk, I will overview our works in this research area; starting with BitDew, a middleware for large scale data management on Clouds and Desktop Grids. Then I will present our approach to enable MapReduce on Desktop Grids. Finally, I will present our latest results around Active Data, a programming model for managing data life cycle on heterogeneous systems and infrastructures.
The document proposes developing software to enable secure and authorized dynamic group resource management. It aims to implement attribute-based access control and dynamic delegation of access rights to address limitations in existing group-centric applications. The research plan involves three phases: literature review and requirements analysis; core implementation of access control and delegation features; and testing, performance analysis, and real-world deployment. The proposed software would facilitate secure collaboration and resource sharing for educational institutions and organizations.
Network flow monitoring tools provide essential network visibility functions beyond simple flow monitoring. They offer features like DDoS mitigation, SNMP integration, API access and reporting. Popular open source tools include Argus, NFDUMP/NFSEN, pmacct, and NTOP/NTOPNG. Commercial tools like Nimbus, NetVizura, Arbor Networks, and Fastnetmon provide additional capabilities like threat intelligence feeds, machine learning, and cloud-based solutions. Most tools collect NetFlow/IPFIX and can analyze traffic trends, top applications/protocols, and detect anomalies.
On SDN Research Topics - Christian Esteve RothenbergCPqD
This document summarizes Christian Esteve Rothenberg's research interests in software-defined networking topics. It outlines his background and experience in SDN and lists several areas of focus, including SDN in the WAN with a focus on software-defined IP routing. It also discusses high performance SDN stacks, building high availability into SDNs, and exploring the integration of optics and electronics with SDN programmable abstractions and datapaths. Rothenberg's research aims to advance these topics through ongoing work and collaborations.
The team interviewed 14 stakeholders to understand challenges with intelligence, surveillance, and reconnaissance for the 7th Fleet. They learned that sensors exist but are often too expensive, managing open source data is difficult, information sharing within the Navy is problematic, and continuous monitoring is not necessary. The team proposed an initial minimum viable product of diagramming the entire ISR infrastructure with a focus on aggregating data.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

to block malicious behaviors
• (if you can afford to buy analyzers)
3/11
4. Speeding up data analysis
• As special-purpose devices are
expensive, research focused on speeding up
analysis by efficiently using general purpose
devices:
– Speeding up iNFAnt (tool for the analysis
through regex-based string matching in GPUs)
– Proposing a distributed analysis approach
4/11
5. Improving NFA speed: problems
• iNFAnt uses NFAs to represent rule sets.
• A technique called Multistride can transform
NFAs to make them n times faster to process
– The transformation is a slow process, with
current tools
– Obtaining 4x NFAs might require months of
processing. If the NFA is too complex, it might
not even be feasible
5/11
6. Improving NFA speed: solutions
• Faster algorithms have been developed, to “push
forward” Multistride limits.
• An alternative technique, called Multi-Map
Multistride has been developed
– It further pushes forward Multistride limits
– It enables iNFAnt to make a better use of the GPU
Results:
up to 4x higher throughput on medium-sized NFAs
up to 3x improvement on big rule sets that could not
be speeded up at all by previous tools
6/11
7. Distributed analysis approach
• Using several devices can increase maximum
analysis throughput
• Why not re-using already available
devices, like devices under analysis, to process
data?
– Smart re-use of existing resources
– More information can be extracted from data
– Network traffic overhead due to analysis is
contained
– BUT: devices must not be overloaded 7/11
8. Distributed analysis approach
• Results: the DELTA Framework
– It allows to re-write data analysis algorithms as

Hello to everybody, I’m MatteoAvalle and I’m here to perform my last annual Oral Presentation for Ph.D Evaluation.
This presentation can be divided in three main sections: at first I will give you some insights about the motivations that led me to follow the research path I am going to describe, then I will delve more in detail about the two research directions I followed in these years; first I will discuss about my main research topic, regarding how to speed up data analysis and making its adoption cheaper than before, then I will talk about my secondary research topic, regarding how to make actual protocol design techniques, based on formal methods, more simple to perform and less error prone.
The main reason that led me to choose these two research paths is that, quite curiously, even if it is not possible to give absolute guarantees abut the robustness of a network to a certain type of attacks, there already are several tools that can be of great help: for instance, thanks to the usage of formal methods, it is already possible to reassure customers about the security properties of a communication protocol with a very high level of confidence. On the other hand, after that communication protocols have been implemented, it is even possible to further increase the robustness of a network by using traffic analysis techniques to identify malicious behaviors.However, as you can read in this slide, both these solutions are often inapplicable, either because formal methods are a research branch that is still restricted to an extremely reduced amount of experts and because traffic analysis could be extremely expensive, especially when special purpose analyzers have to be used.Finding a solution to these two issues represented my main research focus, during the past three years.
A much cheaper alternative to hardware analyzers is the use of software solutions on general purpose hardware. However, with the current techniques, using general purpose hardware creates several potential processing bandwidth issues: my main research topic regarded pushing forward these processing bandwidth limits by increasing the performance of iNFAnt, a regex-based packet processor that exploit the parallelism of GPUs. Then, in the last months, I focused more on taking advantage of another type of parallelism by distributing the data analysis workload to several devices. As it will be shown in few slides, this change of approach does not just improves performance but it also has a series of additional benefits.
But let’s focus on iNFAnt, first: this tool uses NFAs, nondeterministic finite state automata, to represent rule sets. Thanks to this representation the packet processor can be implemented as a simple finite state machine, with the peculiarity that its processing speed can be increased by taking advantage of the high level of parallelism of modern GPUs. In order to further increase performance, a technique called Multistride can be used to transform NFAs and make them several times faster, at the cost of an higher automaton complexity. However, existing techniques were extremely slow and only applicable to very small and poor NFAs.
For this reason, at the beginning of my Ph.D. course I focused on creating alternative, faster algorithms to push forward the maximum speedup achievable in reasonable times by Multistride optimization and, at the same time, to enable it to work on bigger automata (representing more complex rule sets).Then research focused on creating a different flavor of Multistride, called Multi-Map multistride, that not only pushes forward intrinsic limits of regular Multistride, by generating simpler automata after each iteration, but it also increases the degree of parallelism of the packet processing problem, thus allowing to use GPUs in a more efficient way.Using these techniques of reference rule sets allowed to experience the throughput increase you see at the bottom of this slide: medium-sized NFAs could be sped up up to 4 times more than by using previous techniques, while bigger rule sets that could not be used with previous multistride techniques can now be sped up up to 3 times.
An alternative approach to the processing throughput limits is to simply increase the amount of devices involved. However, buying new devices can be expensive, while relying on data centers might generate additional issues. For instance, how much does it cost to send all the data that have to be analyzed to a remote data center?Aware of these issues we posed ourselves this question: why can’t we re-use resources we already have at our disposal, before considering using additional hardware? We decided, then to study what could happen if part of the data analysis tasks could be performed on the same devices producing the network traffic.This simple change of approach provided several benefits, many more than a mere workload reduction: the first one regards the fact that thanks to the advantageous position in which data is analyzed, it is possible to extract more information about it. Moreover, as data is pre-processed before leaving devices, the network overhead necessary to send data to the analyzer is minimized. However, these advantages comes with a cost: since we are re-using existing devices, we must not overload them, otherwise we would be degrading the performance of services that were already running on these devices.
As solving this problem might make algorithm development extremely complex we implemented a specific framework, called DELTA (Dynamically Evolving Lightweight Task Allocator): with this framework developers only have to define data analysis algorithms as an oriented graph of processing blocks, and the framework will automatically take care to duplicate, merge and move these blocks across all the devices in a network in order to balance workloads and maximize the amount of processing performed before sending data to the “central” processing unit that merges together all the processing results.
As result of the described research projects a conference paper has been published, a journal paper has been submitted and it is under evaluation from IEEE/ACM Transactions of Networking, while a conference paper regarding the DELTA framework is under preparation and it is expected to be submitted by the end of November.
Now let’s take a step back and let’s focus on my secondary research topic, regarding formal methods: as anticipated, with formal methods it is possible to mathematically prove robustness of a protocol from a certain type of attacks, thus making it a potentially invaluable tool in the hand of developers. However, its main flaw is that using formal methods is very complex: they usually need to define protocol models by using exotic modeling languages, and even running the tools to automatically produce security robustness proofs is not easy as it is necessary to perform the right questions to these tools: otherwise, their output is worse than useless.For this reason we decided to develop the JavaSPI framework: as you can see in this slide, its main purpose is to allow developers to define abstract protocol models by using a very known programming language, Java. After the model has been defined (and eventually compiled and debugged, as we are dealing with java code we have lots of possibilities to validate its proper functioning), the JavaSPI framework takes care to automate two of the most error-prone tasks: the generation of formal proofs and the generation of concrete, interoperable, implementation code of the defined protocol. Both these operations are performed semi-automatically, so that developers still have control over them, but the level of expertise required to perform these operation is way lowered if compared to equivalent existing formal methods tools.
As a result of this three-year period of research in this field, the JavaSPI framework has been developed along with a case study regarding a particular configuration of the SSL 3.0 handshake protocol. This led to publish a conference paper to the ARES conference in Vienna and a further extended version of the same paper has been accepted by the IJSSE journal.Then, another paper has been prepared regarding mathematically proving the soundness of the JavaSPI framework. This means mathematically proving that security properties proven for the abstract protocol model are also applicable to the implementation code. We plan to submit this paper in the next months.Finally, a survey paper discussing about state of the art of formal methods has been accepted from the FAoC journal, this year.
As expected future works, it is possible to say that all the three tools presented today have room for improvement: their functionality can be expanded, part of their algorithms could be revised and new solutions can be studied to further improve actual results.Moreover, for the DELTA Framework in particular, there are even more possible future works: its working principle, regarding a “smart” way to distribute workloads among devices, has several additional application fields, especially when combined with other research projects. For instance, this framework could be combined with the iNFAnt tool or even with some other research projects that are currently active at the polytecnic, like the FROG programmable router developed by I.Cerato and F.Risso
