An architecture for effort estimation of solutions donatien koulla moullaIWSM Mensura
This document proposes an architecture for estimating the effort required for software projects based on open source software. It acknowledges that existing effort estimation models do not account for the differences in open source projects, including volunteer development teams and lack of formal management.
The proposed architecture includes estimating the effort to integrate open source components, the effort related to the number of code changes, and the effort related to code complexity. It also accounts for functional and non-functional requirements, as well as characteristics specific to open source software development like the voluntary nature of contributions. The total effort is estimated as the sum of efforts across each project activity.
Software Architecture and Agile: Is it Unrequited Love?Michael Keeling
Nobody would argue that Agile software development and software architecture don't go hand in hand together, and yet it seems that the software architecture community is much more interested in agile topics than the agile community is in software architecture topics. Is this a case of unrequited love?
This presentation explores this question and explores a few possible reasons why this perception of unrequited love between software architecture and agile might exist.

Microservices: Architecture to Support AgileEberhard Wolff
1. Microservices architecture divides applications into small, independent components called microservices that can be developed, deployed and scaled independently.
2. This architecture aligns well with agile principles by allowing individual teams to focus on and deploy their microservice without coordination, enabling faster feedback and continuous delivery of working software.
3. By structuring the organization around business domains rather than technical components, microservices help drive organizational communication patterns that mirror the architecture, avoiding misalignment over time.

Why We Need Architects (and Architecture) on Agile ProjectsRebecca Wirfs-Brock
This is an updated version of this talk which I will present at Agile 2013.
The rhythm of agile software development is to always be working on the next known, small batch of work. Is there a place for software architecture in this style of development? Some people think that software architecture should simply emerge and doesn’t require ongoing attention. But it isn’t always prudent to let the software architecture emerge at the speed of the next iteration. Complex software systems have lots of moving parts, dependencies, challenges, and unknowns. Counting on the software architecture to spontaneously emerge without any planning or architectural investigation is at best risky.
So how should architecting be done on agile projects? It varies from project to project. But there are effective techniques for incorporating architectural activities into agile projects. This talk explains how architecture can be done on agile projects and what an agile architect does.
Software Architecture and Project Management Module II archetype patternsreeja_rajesh
The document discusses various archetype patterns including the Party archetype, Customer Relationship Management (CRM) archetype, and Product archetype.
The Party archetype represents people and organizations and captures essential information about them. The CRM archetype aims to manage relationships between businesses and customers to understand and increase customer value. It focuses on having a unified customer view.
The Product archetype models goods and services that businesses sell. There are three broad categories of products: unique things, identical things, and identifiable things. The archetype can be specialized into pleomorphs like UniqueProduct and IdenticalProduct depending on business needs.
The document discusses architecture-centric software development processes. It describes traditional waterfall and iterative development models, and notes that iterative models allow for more flexibility to changing requirements. Agile development methods like eXtreme Programming (XP) are discussed, which emphasize iterative development, collaboration, and rapid delivery of working software. Key practices of XP are outlined, including user stories, testing, pair programming, refactoring, and continuous integration. The role of architecture in agile processes is also addressed.

Microservices: Architecture for Agile Software DevelopmentEberhard Wolff
This document discusses microservices architecture and how it enables agility. It defines microservices as small, independent units that can be developed and deployed autonomously. The document argues that microservices align with the principles of the Agile Manifesto by allowing teams to work independently, facilitating continuous delivery, and making the architecture adaptable to change. Some benefits outlined are improved scalability, maintainability, and ability to replace services easily. The conclusion is that by structuring an organization and software architecture around microservices, greater agility can be achieved compared to a monolithic architecture.
This document discusses the relationship between enterprise architecture (EA) and project and portfolio management (PPM). It argues that EA and PPM have different but complementary perspectives in helping an organization translate strategy into realized value through portfolios and projects. The document provides examples of how EA and PPM can collaborate more effectively by having EA guide the enterprise towards its target state while PPM drives the enterprise strategically forward. It also provides a sample collaboration model where EA and the project manager work together on project architecture.
Transforming Software Architecture for the 21st Century (September 2009)Dion Hinchcliffe
Evolving an important theme I've been working on and presenting all year, this new deck summarizes how enterprise architecture and large scale technology-based business solutions must transform to be more effective in the 21st century.
Contains material on a hypothesis for what's wrong with today's EA as well as potential solutions of merit such as emergent architecture, WOA, enterprise REST, open supply chains (APIs), mashups, and other models.
Presented this week in Oslo Norway to Bouvet's enterprise architecture council.
Management is so important on agile delivery teams that we do it every single day, but that doesn't imply that we
need team managers. Having said that, there are still some manager roles needed, albeit far fewer than in the past, when we scale agile both tactically and strategically within our IT organizations. So where do the rest of the
managers go?
This presentation examines what happens to traditional managers when their organization adopts agile and lean strategies. We work through the implications of several critical forces that enable us to thin out the ranks of middle management. First, agile methods push many technical management tasks into the hands of the team, thereby taking that work away from managers. Second, leadership tasks are assigned to new team roles such as the Product Owner, the Team Lead/Scrum Master, and the Architecture Owner. Third, the move away from a project-based mindset to a product-based one results in stable teams that require far less functional/resource management. Fourth, application of business intelligence technologies to implement automated team and portfolio dashboards reduces the need for manual status reporting.
Some management-oriented work remains. Teams that haven't yet automated reporting will find that someone needs to track and report progress. Large teams, also known as program teams, will likely need a Program Manager or more accurately a Program Coordinator. To support IT-level functions you are likely to need people in roles such as Portfolio Manager, Operations Manager, Help Desk Manager, and Community of Practice (CoP) Lead. Managers are still clearly needed, but in practice there tends to be far fewer management positions within agile organizations than what we find in traditional ones. This implies that many existing managers will need to reskill and transition into one of the new agile roles. The good news is that there is room for everyone within agile if they're willing to learn new skills and change with the times.
Computer Information Systems and the Electronic Health RecordRebotto89
Paper-based health records are being replaced by electronic health records (EHRs) to improve patient care. A clinical information system (CIS) is a collection of applications that provides centralized access to patient information across locations. Choosing a CIS requires input from all users and consideration of costs, which can range from $1-2 million for small hospitals to over $1 billion for large hospitals. Ensuring security of patient data and regular system updates are also important factors in selecting and implementing a CIS/EHR.
This document proposes a two-step conceptual model for an anonymous patient-researcher matching system. It describes a three-user class account structure that allows patients to remain anonymous while still managing their data and preferences. The classes include anonymous users, confidential users who provide encrypted identity information, and physician/researcher users who are verified. It also outlines a four-step engagement method for anonymous communication between matched patients and researchers. The goal is to increase data quantity and quality for research by addressing privacy concerns and promoting trust in the system.
The document discusses computer-based patient records for anesthesia. It notes that Cushing-Codman made the first ether chart for keeping anesthesia records. Computerization allows for easy retrieval of data which is an important advantage. Hospital information systems can have a monolithic or "best-in-breed" model. The monolithic system has smooth interoperability but some components may be inferior. Electronic health records provide tools for provider communication and access to population data for research. Specialty electronic health records have been developed including for anesthesia, emergency departments, and intensive care units.
The document discusses various aspects of electronic health records (EHRs), including their components, cost, structure, safety considerations, and education. It describes the eight main components that make up an EHR: health information and data; results management; order entry management; decision support; electronic communication and connectivity; patient support; administrative processes; and reporting and population health management. It also addresses how to structure an EHR for ease of use, the costs associated with EHR software, implementation, hardware, and ongoing support, and the importance of safety measures to protect patient information. Finally, it outlines strategies for training all staff on a new EHR system in a short period of time.
This document outlines training that could be provided to hospital staff to avoid improper access of celebrity health records. It proposes the following training:
1. During orientation, all employees who can access patient information must be trained on confidentiality, privacy and security rules.
2. Patients' information can only be accessed by staff directly involved in their treatment, and all access is logged.
3. Monthly audits of access records would detect any improper browsing of files. Violators would face discipline.
The training aims to educate staff and put accountability measures in place to ensure patients' confidential health information is appropriately protected.
This document describes a proposed blockchain-based hospital management system that incorporates machine learning and other technologies. The system would allow hospitals to securely store patient medical records and enable patients to access their records anywhere. It also includes features for online prescription management, medicine purchasing, and data analytics to help governments and organizations monitor health trends. The system is designed to address issues with conventional systems by providing centralized, transparent access to data while preserving patient privacy through blockchain and other security measures.
mMR is a mobile medical records application developed by Kloud Data that allows healthcare professionals to access patient records from mobile devices. The application provides access to a patient's full medical history, test results, prescriptions, notes and can be used to discharge patients. It has a user-friendly interface compatible with Android and iOS devices. The application ensures security by not storing patient data locally and requiring authentication. Implementing mMR provides doctors access to patient information anytime, improves hospital operations and supports high-quality patient care both inside and outside of hospitals.
Ehr by jessica austin, shaun baker, victoria blankenship and kayla borokayla_ann_30
This document provides an overview of electronic health records (EHR) including what they are, key components, considerations for implementation, and security and costs. It discusses that EHRs provide a centralized digital patient record accessible by healthcare providers. The eight essential components that must be included are things like health information, order entry, decision support, and administrative functions. Proper implementation requires input from various stakeholders like medical staff, IT, and leadership. Security and privacy are also important considerations, as are the financial costs of purchasing and maintaining an EHR system.
This document describes a patient management system project for a university. The system aims to automate a hospital's manual patient record keeping system. It will computerize patient, doctor, and hospital details to make record keeping more efficient. The system will allow scheduling appointments, tracking medical bills and patient rooms. It will generate reports on patient information and utilize databases to store records. Diagrams including data flow diagrams and entity-relationship diagrams are provided to illustrate the system's design and data structure.
The document proposes an architecture and process for nationwide patient-centric consent management. It discusses the need for improved electronic consent management given the limitations of paper-based consent. The proposed approach uses an internet-based consent service that stores a patient's consent preferences in one place and can provide the most current preferences to any record holder. This allows patients to manage consent in a centralized way without needing to interact directly with each individual record holder. The proposed architecture aims to balance the needs of patients, providers, and other stakeholders to enable greater data sharing while respecting patient privacy preferences.
1) The document discusses the implementation of electronic medical records (EMRs) on mobile devices and the security risks this poses. It proposes adding audit checks throughout the EMR access and usage process to monitor for abnormal behavior.
2) Role-based access control (RBAC) is introduced to limit employee permissions to only what is needed for their role. This prevents unauthorized access to patient information.
3) While privacy of medical records is important, the document argues that patients should have access to their own records upon request rather than going through lengthy processes. However, most patients currently lack the health literacy to manage their own records securely.
This document summarizes privacy, security, and professionalism considerations for digital communications among health care professionals and between professionals and patients. It discusses how HIPAA and state laws apply to electronic communications. Encryption is recommended but not required under HIPAA. Professionals must take care to send information to the right recipient and patient. Communications should maintain professional standards regardless of format. Guidance from medical societies can help set policies for using digital tools. The document also briefly discusses FDA regulation of mobile medical apps and acceptance of data from patients.
An AI-based Decision Platform built using unified data model, incorporating systems biology topics for unit analysis using semi-supervised learning models
This document provides an overview of key regulatory and legal issues related to health IT, including various acronyms. It summarizes regulations from HIPAA, HITECH, the FTC, FDA, ECPA, SCA, FCC, and CMIA. HIPAA and HITECH establish privacy and security rules for health information. The FTC protects consumer privacy and enforces data breach notification. The FDA regulates medical devices, including some software. ECPA/SCA limit sharing of electronic communications. The FCC regulates communications carriers. CMIA is California's health privacy law.
This document proposes a medical records management system called MedBlock that uses blockchain technology. The system aims to allow patients secure access to their medical information across different healthcare providers in an immutable and verifiable way. It also aims to help streamline the medical insurance claims process by allowing insurance agencies to securely access authenticated patient records and invoices on the system. The system would use blockchain properties like encryption, authentication, and smart contracts to record medical records and control access permissions. This could help reduce insurance fraud and improve the response time for claims. The proposed system aims to address current issues with medical record security, accessibility, and insurance claim processing.

IRJET- MedBlock System for Securing Medical RecordsIRJET Journal
This document proposes a blockchain-based system called MedBlock to securely store and share medical records. The system aims to address limitations in current healthcare record systems related to privacy, security and data sharing. MedBlock uses blockchain technology and encryption to securely record medical transactions in an immutable ledger. It allows doctors to upload encrypted medical records and patients to access and share records through decryption keys. The system architecture includes modules for doctors and patients. If implemented, MedBlock could provide more secure, private and tamper-proof management of healthcare data compared to traditional electronic medical record systems.

Kick starter project secure computing infrastructure for real-time embedded ...W Fred Seigneur
This document describes different pledge levels for supporting a project to develop a secure computing infrastructure for real-time embedded applications. Higher pledge levels provide increased benefits like acknowledgement in reports, project updates, merchandise, access to the development team, and at the highest levels, participation in project meetings and testing. The highest pledge level of $15,000 provides the opportunity for a computer vendor to supply development systems and participate in all platform development phases.
This document discusses computer security innovation and proposes a Secure Computing Infrastructure (SCIF) as a foundational solution. Some key points:
- Current computer security approaches are unsustainable and non-scalable as they do not build security in from the beginning.
- Operating systems and applications lack basic immune systems and are not written robustly, leading to vulnerabilities.
- The document proposes a SCIF that uses components like the Parallella board running seL4 microkernel with Erlang virtual machine to securely run applications and provide fault tolerance.
- A phased approach is outlined to prototype and field trial the SCIF as a more secure computing foundation.
This document summarizes Fred Seigneur's presentation on computer security innovation at the 2014 Cybersecurity Innovation Forum. The presentation discussed foundational weaknesses in current operating systems and applications due to a lack of built-in security. It proposed that developing a Secure Computing Infrastructure (SCI) using a separation kernel, Erlang virtual machine, and hardware security could help address these weaknesses by building security in from the beginning. A phased approach was outlined to develop an SCI prototype using the Parallella board.
This document discusses weaknesses in current computer security approaches and proposes a new "Secure Computing Infrastructure" (SCI) approach. It notes that operating systems and applications currently lack basic immune systems to defend against attacks. The SCI would integrate existing components like a separation kernel and Erlang virtual machine to create a more secure fault-tolerant environment. A phased approach is proposed beginning with a feasibility study and moving to proof of concept, field trials, and eventual full implementation. The goal is to develop a foundational security solution that is taught more widely in education.
The document discusses meditations on the Kingdom of God presented by Fred Seigneur to the Tuesday Home Group. It defines the Kingdom of God as the dominion or domain of God, which includes the spiritual realm over which God reigns as sovereign. It explores how one can see and enter the Kingdom by being born again of water and spirit. The Kingdom of God is likened to many believers linking up through yielding control of their lives to God, represented by cell phone towers or satellite beams providing coverage. This state of being in the Kingdom places one under the protection of God's wings.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

Only two Medical Groups, each with at least two doctors and 3 patients will be included
in the Prototype. No Hospital or Independent Laboratory will be modeled in the
Prototype.
All data will be pre-loaded into the Prototype database. The Prototype will include no
on-line input of data. The intent of the prototype is to demonstrate that sensitive patient
data is only allowed to be accessed by authorized doctors over secure connections.

Data will be stored on disk on the Linux host. Doctors will authenticate themselves using
userid and password. Data will only be provided to Doctors who are authorized to access
it, based on their login. SSL or other encryption will protect all data transfers from being
observed while it traverses the Internet or the wireless Access Point.
Furthermore sensitive patient data will only be transmitted using PGP encryption using
the public key of the Doctor who is logged in. Thus, even if an authorized Doctor’s
userid and password are compromised, the data will be useless unless the perpetrator alsh
has the Doctor’s private key and pass phrase. Appropriate PGP keys will be installed on
devices for each doctor. If an unauthorized user acquires the laptop the thief will still
need the doctor’s userid, password and pass-phrase.
4. Exhibit A
Privacy Policy
In the case of medical information, the issue is potential violation of the Doctor-Patient
confidence, which is a privilege protected by law. The violation of this privilege can
result in loss of a doctor’s or group of doctor’s right to practice medicine as well as
damage suits from patients, and possible criminal charges.
Therefore, we make the following assumptions:
· Doctors, Hospitals, Labs and their professional and support personnel are aware of
the risks of violating patient privacy. The requirement on Medsoft/Mammoth is to
ensure that automated systems developed and marketed by the Medsoft/Mammoth
team do not compromise Doctor-Patient Privilege.
· Individual client organizations (Doctors’ Offices) may exercise their own Privacy
Policy. Individual users, who are certified by the procedures and mechanisms
described in the Concept of Operations and elsewhere in this document, are at liberty
to reveal or protect information obtained from automated systems just as they are
with existing paper and automated records.
Description of Subjects and Objects
In order to define a Privacy Policy, we first defined Subjects, Objects and Relationships,
which were then used to create rules defining cases where it is acceptable for information
relating to a specific patient to be revealed to a particular Medical Group/Doctor.
The diagram below is an initial model of the entities involved in transactions involving
Medsoft. The principal actors (subjects) are the Doctor and the Patient. The objects to be
protected are medical records relating to individual patients. Other entities in the model
are Medical Groups, Hospitals and Independent Laboratories. Sensitive patient
information is maintained by each of these entities, with all rights to such information
being authorized by the Patient and protected by Doctor-Patient Privilege.

Each Patient has at least (and most often only) one Primary Care Physician. Normally
insurance companies require that there be a single Primary Care Physician, although the
Patient has the right to create this relationship with more than one Doctor. This model
accommodates such a situation, however, in this case the Privacy Policy permits Patient
information to be shared only by written consent of the Patient.
Within this model, all doctors are considered to belong to one and only one Medical
Group. Doctors who provide service independently from such a group are considered to
belong to a group of one, that particular Doctor’s practice.
Other Medical Groups/Doctors may provide specialist care to the patient after a referral
from the patient’s Doctor. While a Patient has the right to consul a specialist
independently (without being referred by a Primary Care Physician), this case is modeled
identically to the case where a Patient independently consults more than one Medical

Hospitals provide inpatient and outpatient care to Patients. The inpatient or outpatient
relationship between Patient and Hospital is established by the Doctor’s act of admitting
the Patient to the Hospital (as an inpatient), or referring the Patient to the Hospital for
outpatient services. The authority to admit Patients to a Hospital is based on the fact that
one or more Doctors in a Medical Group Practices at a particular Hospital.
Similarly, a Doctor who is a Member of a Medical Group may (through the Medical
Group) Outsource Tests to an Independent Laboratory. The term Independent Laboratory
is a generic term for all such organizations that do blood work, x-rays, etc. Such
organizations may also provide interpretative services (such as a radiologist’s reading of
an X-ray or Cat Scan).

CDI to a valid final state, given that it is in a valid state to begin
with. For each TP, and each set of CDI’s that it may manipulate,
the Security Officer must specify a “relation”, defines that
execution. A relation is thus of the form: (TPi, (CDIa, CDIb,
CDIc...)), where the list of CDI’s defines a particular set of
arguments for which the TP has been certified.
C3 The list of relations in E2 must be certified to meet the separation

C4 All TP’s must be certified to write to an append-only CDI (the log)
all information necessary to permit the nature of the operation to
be reconstructed.
C5 Any TP that takes a UDI as an input value must be certified to
perform only valid transformation, or else no transformations, for
any possible value of the UDI. The transformation should take the
input from a UDI to a CDI, or the UDI commercial is rejected.
