This is a summary of the book titled “Building Ontologies with Basic Formal Ontology” written by Robert Arp, Andrew Spear and Barry Smith and published by MIT Press, 2015. Modern scientific research is producing data at a pace and scale that far exceed the capacities of traditional analytical methods. This transformation is especially visible in the life sciences, where advances such as high‑throughput gene sequencing and multidimensional imaging generate vast amounts of information every day. As researchers confront this deluge of data, the question of how to store, integrate, interpret, and share it efficiently has become increasingly urgent. Robert Arp, Andrew Spear, and Barry Smith address this challenge, presenting ontology as a powerful solution for achieving interoperability, accessibility, and coherence across scientific domains.
Ontologies, as the authors explain, emerge from philosophy’s long tradition of studying what exists and how different entities relate to one another. In contemporary scientific and computational contexts, an ontology functions as a representational structure—essentially, a taxonomy—designed to categorize and relate types of entities according to their defining characteristics. A classic example is the familiar biological hierarchy that starts with broad categories such as “vertebrate animals” and branches into more specific groups such as mammals, reptiles, primates, and snakes. Such structured classification enables scientists to clarify how individual items fit within broader categories, enhancing clarity and communication.
This philosophical grounding underlies the ontology’s central purpose: representing reality as faithfully as possible. Ontological realism—the idea that the categories and relations described in an ontology correspond to entities in the real world—plays an important role here. For instance, the classification “mammal” is not a linguistic convenience but a label for a genuine biological class of organisms. Ontologies used in applied fields such as biomedical informatics depend on this realism, enabling researchers to use consistent terminology and shared conceptual frameworks across diverse technological platforms.
The authors distinguish among different kinds of ontologies, showing how they operate at varying levels of specificity. A general ontology might describe broad types of organisms, while a domain ontology focuses on particular systems or phenomena—such as the human heart, with its chambers, valves, and functions. Domain ontologies are indispensable for specialized research areas, but they also risk creating isolated conceptual systems that do not integrate well with each other. To avoid this fragmentation, the authors emphasize the importance of beginning every ontology with universal, top‑level categories that provide a common foundation for more specific structures. This top‑down approach improves interoperability and supports scientific collaboration across disciplines.
Designing an effective ontology also requires adherence to several foundational principles. Ontologists must assume the existence of real-world entities, acknowledge the complexity of systems, recognize the limitations of scientific theories, and strive to represent reality as accurately as possible given current knowledge. They must also design ontologies so that entities at various levels of granularity—from broad categories to fine distinctions—can be represented. Because science evolves, ontologies must remain flexible, open to revision as new discoveries emerge.
Basic Formal Ontology (BFO) framework distinguishes between continuants and occurrents. Continuants are entities that persist over time while retaining their identity—like a human being or a piece of fruit—even though their parts may change. Occurrents, by contrast, are processes or events unfolding in time, such as infections or biological functions. These two types of entities require different representational strategies, and BFO provides the conceptual tools to integrate both within a single coherent ontology.
The relationships among entities are equally crucial. Ontologies go beyond hierarchical classification, incorporating relationships among universals, between universals and particulars, and among individual entities. These relational structures reflect the complexity of scientific reality—for example, the shared atomic composition of different organisms or the dependence of certain qualities on larger structures.
An ontology must become a practical tool—not just a conceptual model but a computer‑implementable artifact. Using tools such as the Protégé ontology editor and the Web Ontology Language (OWL), ontologists translate conceptual structures into software systems capable of supporting large‑scale data analysis and knowledge integration. These digital ontologies already underpin major scientific efforts in fields ranging from cell biology to mental health research.
Through their systematic exposition, Arp, Spear, and Smith demonstrate that ontologies, when properly constructed, serve as vital infrastructure for modern science. They provide the shared language and structure necessary to manage overwhelming volumes of data, bridge disciplinary divides, and ensure that scientific knowledge remains coherent, accessible, and continually adaptable.

Aireon’s space‑based ADS‑B network creates a continuous, global fabric of aircraft position, intent, and navigation integrity, and when this fabric is woven together with the ground‑truth richness of our drone video analysis framework, an unusually powerful form of situational intelligence emerges. Aireon’s constellation delivers real‑time surveillance data from pole to pole, capturing every ADS‑B equipped aircraft even in regions where ground infrastructure is sparse or nonexistent. This uninterrupted visibility provides the aviation ecosystem with a reliable, safety‑grade stream of positional information, enriched with contextual layers such as weather, airspace structure, avionics details, and schedule data through products like AireonSTREAM and AireonFLOW Aireon. Our framework, by contrast, excels at interpreting the world from below—extracting semantic meaning, behavioral patterns, and environmental cues from drone video feeds. When these two vantage points meet, the result is a multi‑layered operational picture that neither system could achieve alone.
The synergy begins with Aireon’s ability to establish a trusted “truth position” for aircraft, even in the presence of GPS interference or spoofing, using multilateration and time‑difference‑of‑arrival techniques enabled by the Iridium satellite constellation International Civil Aviation Organization (ICAO). This resilience becomes a foundation upon which our drone analytics can anchor their own observations. For example, when drones are deployed near airports, critical infrastructure, or remote air corridors, our system’s object detection, tracking, and semantic labeling can be fused with Aireon’s verified aircraft tracks to create a unified air‑ground awareness layer. This fusion allows operators to distinguish between legitimate aircraft behavior and anomalies, correlate drone‑observed events with aircraft trajectories, and validate or challenge sensor‑level interpretations with Aireon’s independent positional truth.
Aireon’s global reach also expands the operational envelope of our framework. Because Aireon’s surveillance is not constrained by geography, our drone analytics can be deployed in remote or oceanic environments with the confidence that aircraft movements above the operational area are fully known. This is particularly valuable for missions involving search and rescue, environmental monitoring, or maritime operations. AireonINSIGHTS and Aireon Locate already support first responders by helping them pinpoint aircraft in distress Aireon, and our drone video analytics can extend that capability by providing visual confirmation, terrain interpretation, and fine‑grained scene understanding once drones arrive on‑site. The combination transforms what would otherwise be a purely positional alert into a multi‑modal, context‑rich response workflow.
There is also a natural complementarity in how both systems handle prediction and flow management. AireonFLOW enhances the forecasting of air traffic demand by combining surveillance data with contextual information Aireon. Our framework, with its ability to detect ground‑level activity patterns, infrastructure conditions, and environmental changes from drone video, can feed additional signals into these predictive models. For instance, drone‑observed congestion on airport surfaces, construction activity near runways, or unexpected weather‑driven ground effects can be integrated with Aireon’s airspace‑level predictions to create a more holistic operational forecast. This synergy supports more efficient airspace management, reduces delays, and strengthens safety margins.
Security and integrity monitoring represent another powerful intersection. AireonVECTOR provides real‑time detection of GPS interference and spoofing by comparing aircraft‑reported positions with satellite‑derived truth positions Aireon. Our drone analytics can complement this by visually confirming anomalies, identifying potential sources of interference on the ground, and mapping environmental factors that may correlate with navigation disruptions. Together, the systems create a closed‑loop integrity assurance mechanism: Aireon detects the anomaly, our drones investigate and contextualize it, and operators receive a complete, multi‑sensor explanation rather than a single‑source alert.
The synergy between Aireon and our drone video analysis framework lies in the fusion of global certainty with local intelligence. Aireon provides the authoritative, continuous, and resilient picture of the skies; our framework provides the interpretive, high‑resolution understanding of the world below. When combined, they form a vertically integrated sensing ecosystem capable of supporting safer airspace operations, richer situational awareness, and more responsive decision‑making across aviation, emergency response, infrastructure monitoring, and environmental stewardship.

This is a summary of the book titled “The Eight Paradoxes of Great Leadership: Embracing the Conflicting Demands of Today’s Workplace” written by Tim Elmore and published by HarperCollins Leadership, 2021. Tim Elmore asserts that leadership today is more complicated, more demanding and more paradoxical than ever before. As rapid technological advancement, global connectivity and shifting societal expectations reshape the workplace, the qualities that once defined effective leaders are no longer sufficient. Elmore argues that today’s most impactful leaders are those who can embrace contradictions—who can be both confident and humble, both firm and flexible, both teachers and lifelong learners. Through vivid stories drawn from history and contemporary life, he illustrates how these opposing traits converge to create the “uncommon leaders” needed in an era of volatility.
Elmore begins with the forces that have transformed leadership itself. The traditional command‑and‑control style that once dominated industrial organizations has given way to models built on collaboration, emotional intelligence and adaptability. Employees and consumers are more informed and less loyal to established institutions. The COVID‑19 pandemic accelerated trends toward remote work, autonomy and a values‑driven workforce. In this fast‑moving environment, leaders must possess a rare blend of attributes that often seem to contradict each other.
This dynamic is visible in the lives of iconic figures. Isaac Newton, for example, used the enforced isolation of the Great Plague to rethink long‑established assumptions, leading to transformative breakthroughs in mathematics and physics. His story reveals how disruption can fuel creativity for leaders willing to step back, question norms and imagine new possibilities.
The paradox of confidence and humility shows up in the career of Bob Iger. When he became CEO of the Walt Disney Company, he lacked the bold charisma of his predecessors. Yet his quiet confidence—and willingness to rely on others’ expertise—enabled him to rebuild trust, empower teams and guide Disney into a new era of innovation. Elmore uses Iger to demonstrate that humility is not weakness but a strategic strength that allows leaders to inspire loyalty and make better decisions.
The need for vision balanced by awareness of blind spots is embodied in entrepreneur Sara Blakely, whose lack of industry experience led her to create Spanx and pioneer the shapewear category. Blakely’s fresh perspective—combined with relentless experimentation—illustrates how inexperience can spark innovation when paired with curiosity and resilience.
Other paradoxes highlight the moral dimension of leadership. Martin Luther King Jr. exemplifies a leader who publicly championed transformative goals while quietly building a movement sustained by countless organizers and supporters. Samuel Truett Cathy, founder of Chick‑fil‑A, demonstrates how steadfast convictions can coexist with openness to new ideas—so long as those ideas align with core values. Mother Teresa shows how leaders can be both deeply personal and broadly influential, offering individual compassion while inspiring large‑scale change.
Elmore also emphasizes the importance of learning and teaching, citing figures like Michelangelo, Pablo Casals and Steve Jobs—individuals who remained students of their craft even at the height of mastery. The paradox of excellence and forgiveness appears in stories of Harriet Tubman and Golden Gate Bridge engineer Joseph Strauss, who demanded the highest standards while understanding that mistakes are inevitable on the path to achievement.
Finally, Elmore reminds readers that the most enduring leaders ground themselves in timeless values. Walt Disney’s commitment to excellence, imagination and human storytelling allowed him to create works that resonated across generations.
Through these narratives, Elmore paints a compelling picture of leadership built not on rigid formulas but on embracing complexity. In a world rife with uncertainty, the leaders who will shape the future are those who can live comfortably within paradox—balancing strength with vulnerability, conviction with curiosity, and ambition with empathy.

Public Cloud Basis:
Public cloud known for its ubiquity, cost-effectiveness and pay-as-you-go model is appealing to host an analytical framework that can collect traffic from anywhere in the world. We chose Azure in our case study but the use of an public cloud is not only feasible but also recommended for replicating the study and most public clouds offer parity in the features used with our analytical framework. Our choice of Azure was based on the <10 ms latency for resources with connections over the Azure high-speed backbone.
The resource types and the cost-calculations are presented here as basis for our studies for cost-effectiveness of drone video sensing analytics that follows next.
Our Pipeline Cost Estimates:

LLM Tokens 1 token 100 Million tokens $0.40 to $30+ per million output tokens
Training+Tuning+Deployment $200 per month
The above costs are inclusive of both CapEx (initial) and OpEx (recurring) costs for realizing a fully functional drone video sensing analytics framework. However, which most of these costs are similar between operational and analytical frameworks stemming from the use of the same resource-types, it must be noted that Operational frameworks lean more on computation power and consumption versus analytical frameworks. With importance-based sampling, the total cost of ownership reduces compute time by a factor of 2 at least as compared to operation-only workloads. Furthermore, analytics frameworks leverage commodity models, commodity compute and fine-grained task-library to leverage only those necessary for a query. Analytical frameworks are also easier to build focusing on narrow tasks and leverage multiple and cheaper compute as opposed to doubling down on expensive compute for everything from training, testing, deploying and predictions.

This is a summary of the book titled “Future-Fit Innovation: Empowering individuals, teams and organizations for sustainable growth” written by Barbara Salopek and published by Practical Inspiration Publishing in 2025. Barbara says innovation is far more than a spark of creativity or a brilliant invention—it is a holistic, human-centered endeavor shaped as much by psychology and culture as by technology. In this insightful guide, she weaves together research, practical frameworks, and compelling examples to illustrate why many innovation efforts stall and what leaders can do to build organizations that continuously evolve, adapt, and thrive.
She opens by dismantling a common misconception: the belief that innovation is synonymous with creativity or invention. A company may generate thousands of clever ideas or file numerous patents, yet genuine innovation only occurs when an idea creates real value and is adopted by people. Salopek highlights this through a familiar example—the mousetrap. Despite more than 4,400 designs approved by the U.S. Patent Office, only a small fraction gained traction, and the Victor Mousetrap succeeded not because it was the most inventive, but because it was the one people actually used. This underscores the distinction between an organization’s capacity to innovate—its processes, tools, and structures—versus its innovativeness—the cultural openness that fuels experimentation, curiosity, and iteration.
Innovation, she emphasizes, is not static. It evolves across waves and cycles, much like the history of the telephone. Landlines rose, mobile phones surged, and both eventually plateaued. Companies that recognized the shift early pivoted toward digital services, layering new value on top of established technologies. This adaptive mindset requires organizations to stay close to customers, respond swiftly to market signals, and empower employees to explore unconventional solutions.
Creativity sits at the front door of this process, yet it is frequently blocked by internal and external barriers. Individuals grapple with fear of failure, perfectionism, and self-doubt, while organizations wrestle with risk-averse cultures, groupthink, and rigid routines. Leaders may not be able to eliminate internal fears, but they can shape environments that expand creative potential. Salopek offers a range of actionable strategies: grounding creative requests in specific challenges, celebrating diverse forms of creativity, mixing solo and group ideation to reduce social pressure, and framing failed experiments as learning opportunities. She encourages leaders to model curiosity themselves—asking questions, sharing unfinished ideas, and embracing ambiguity.
One of the most pervasive obstacles Salopek identifies is functional fixedness: the tendency to view objects, processes, or problems through overly familiar lenses. Whether in a playful hide-and-seek game or in the strategic failures of companies like Nokia and Kodak, fixed thinking narrows the range of possible solutions. To counter this, she recommends the Generic-Parts Technique, which asks individuals to break objects down into their physical attributes and reimagine alternate uses. By shifting focus away from predefined functions, teams can uncover innovative pathways that would otherwise remain invisible.
Diversity, too, is presented as a powerful engine of innovation. A broader array of perspectives—demographic, cognitive, and experiential—helps teams identify blind spots, challenge unexamined assumptions, and adapt more effectively to change. Salopek illustrates how the lack of diversity has historically skewed data and decision-making, such as in clinical trials dominated by white male participants. To truly unlock the potential of diverse teams, leaders must actively dismantle barriers, expand access to opportunities, and cultivate norms that normalize debate and elevate underrepresented voices.
Psychological safety emerges as another foundational pillar. Without it, even the most promising ideas remain unspoken. Drawing on findings from Google’s Project Aristotle, Salopek shows that high-performing teams are those where individuals feel safe to question, disagree, and admit mistakes. Leaders who demonstrate vulnerability, listen actively, set clear expectations, and act with integrity help build the trust necessary for innovation to flourish.
Salopek also explores how technology and sustainability intersect with innovation. Digital tools—from AI to cloud computing—can accelerate growth, but only when aligned with strategic goals and modeled authentically by leaders. Resistance, fear, and habit often slow adoption, making it essential for organizations to invest in learning, experimentation, and long-term value creation.
She argues that sustainability is no longer optional; it is a strategic imperative. Organizations that embrace sustainable thinking gain resilience, reduce costs, and stay ahead of regulatory demands. Integrating circular design, listening closely to shifting customer expectations, and building internal coalitions around sustainability are all critical steps toward future-fit growth.
Through these interconnected themes, Salopek paints a compelling picture: innovation is a collective mindset, nurtured intentionally, grounded in human behavior, and essential for enduring success.

This is a summary of the book titled “Rock the boat: Embrace change, encourage innovation, and be a successful leader” written by Danelle Barrett and published by Greenleaf Book Group Press in 2021. Her book presents the insights of a seasoned Navy admiral who combines the discipline of military leadership with a surprisingly warm, human‑centered approach. Throughout her career, Barrett discovered that there is no singular formula for being an effective leader. Instead, leadership is a dynamic blend of personal authenticity, learned experience, thoughtful decision‑making and the willingness to grow alongside the people you guide. As she reflects on decades of leading high‑stakes teams, she emphasizes that even the most complex challenges can be simplified when approached through genuine human connection.
Barrett stresses that successful leadership requires applying mindful thought to every action. Leaders must model the behavior they expect from their teams, demonstrating integrity, consistency and respect in all interactions. They must help people connect to a sense of purpose, offering clarity, direction and encouragement. In a world marked by constant and rapid change, leaders must not only adapt but also actively drive innovation so their organizations do not fall into the stagnation that once brought down giants like Sears or Blockbuster. Tenacity, courage and the ability to stay undeterred in the face of cynicism are traits Barrett believes inspire others to follow.
Innovation, she argues, is not something to fear but to welcome—carefully. Leaders should be among the first to explore promising new technologies, yet they should do so only after ensuring their organizations’ systems are sound. Adopting technology prematurely simply automates flawed processes. Visionary thinking—considering future disruptions such as autonomous transportation or other emerging forces—equips leaders to anticipate opportunities and steer their teams strategically.
When championing change, communication and transparency become essential. Leaders must articulate the reasons for change clearly, making sure people understand not only what is happening but why it matters and how it benefits them. Some team members will embrace change quickly, while others may resist or hesitate. Barrett encourages leaders to listen to all perspectives but devote most of their energy to those ready to move forward and to the majority who simply need persuasion. Ultimately, leaders must decide and then unify the team behind the chosen path.
Mentorship emerges as one of the most important responsibilities in Barrett’s philosophy. Everyone needs guidance, and strong leaders both seek mentors and become mentors themselves. A good mentor listens deeply, offers honest feedback, challenges assumptions and pushes people to grow beyond their comfort zones. The best mentors never try to create versions of themselves; rather, they help others define their own strengths, passions and goals. Mentoring demands time, humility and patience, but Barrett argues it is among the most meaningful contributions any leader can make.
Equally vital is protecting one’s personal well‑being and life goals. Barrett warns leaders not to sacrifice their families or personal identities in pursuit of career success. By modeling healthy boundaries—taking vacations, respecting weekends and noticing signs of distress among team members—leaders foster environments where people can thrive. An organization that truly values balance avoids the silent cultures where rest is discouraged despite lip service to well‑being.
Holding people accountable is another cornerstone of effective leadership. Leaders must clearly communicate their expectations, uphold standards of ethics and performance, trust their teams with autonomy and avoid the trap of micromanagement. While creativity flourishes in freedom, leaders must reinforce excellence by recognizing achievements and providing direct, unambiguous feedback. Communication, both internal and external, requires careful planning and repetition; messages must be delivered thoughtfully and consistently to ensure understanding.
Barrett also describes the importance of setting priorities and remaining adaptable. During crises—like the COVID‑19 pandemic—leaders must act decisively, communicate openly and maintain a calm, optimistic presence. Crises often create opportunities for transformation, such as the shift toward remote work, and leaders must be prepared to identify and leverage these moments.
Finally, she urges leaders to protect their reputations with the same discipline they apply to their operational decisions. Visibility increases with responsibility, making every action subject to scrutiny. Ethical behavior, humility and emotional intelligence become essential safeguards. Even difficult colleagues offer lessons in what pitfalls to avoid.
Through the lens of her naval career, Barrett shows that leadership is neither rigid nor mysterious: it is the daily practice of engaging authentically with others, inspiring growth, embracing innovation and navigating change with clarity and courage.
