title: Dynamic Integrated National Security Ecosystem (DINSE): A Global Multidisciplinary Framework Integrating AI, Blockchain, IoT, and Robotics for Future-Ready Defense and Security Policy

description: This thesis introduces the Dynamic Integrated National Security Ecosystem (DINSE)—a first-of-its-kind, multidisciplinary framework that reimagines the future of national security in the 21st century.

 

DINSE uniquely integrates Artificial Intelligence, Blockchain, Internet of Things, and Robotics with ethical consciousness, governance philosophy, and civil–military collaboration, creating a rare and holistic ecosystem for defence and strategic innovation.

 

Unlike conventional studies limited to either technology or policy, this research advances a unified security architecture that balances three eternal foundations: Strength (Indra – Power), Dharma (Bharata – Ethical Governance), and Knowledge (Brahma – Wisdom & Creation).

 

As an independent, pioneering contribution, this work aspires to set a new benchmark in international scholarship, offering both theoretical depth and practical pathways for global security, defence policy, and strategic studies. It is envisioned as a reference point for:

 

Policymakers shaping national security doctrines,

 

Military and defence institutions worldwide,

 

International think tanks and academic researchers, and

 

Future curricula in strategic and defence studies.

 

 

DINSE is not just a framework—it is a visionary blueprint for resilience, innovation, and peace in an increasingly complex global order.

title: Opgraving, variant Archeologische Begeleiding, Riolering Sportlaan te Rosmalen, Gemeente ‘s-Hertogenbosch

description: De Sportlaan te Rosmalen (gemeente ’s-Hertogenbosch) ondergaat een reconstructie, waarbij ook het riool gescheiden wordt in een hemelwater- en vuilwaterafvoer. Dit werk is uitgevoerd door Roy Verstegen B.V. Aangezien mogelijk resten van een 19e-eeuws erf aanwezig waren binnen het plangebied, dienden de werkzaamheden voor een gedeelte archeologisch te worden begeleid.
Tijdens de archeologische begeleiding uitgevoerd door Bodac B.V., zijn op 30 september, 1 en 2 oktober 2020 verschillende archeologische resten aangetroffen. Alle sporen en vondsten zijn aangetroffen in het noordprofiel, aangezien de andere profielen en het vlak verstoord waren door de aanleg van het oorspronkelijke riool. De aangetroffen sporen betreffen (afval)kuilen, een vlijlaag met bijbehorende insteek en een uitbraaksleuf. Tijdens de aanleg, maar hoofdzakelijk in de sporen zijn vondsten aangetroffen, welke dateren uit de periode 1700-1900, met de nadruk op de periode 1800-1900. Het betreft aardewerkscherven (van kannen, een bord en een mogelijke komfoor), bouwkeramiek (bakstenen, waaronder IJsselsteentjes, en plavuizen), enkele metalen voorwerpen (knoopjes en recente vondsten), munten (een duit uit 1684 en een 10 cent munt uit 1906) en een vondst van natuurstenen (een slijpsteen).
De aangetroffen vondsten kunnen gekoppeld worden aan twee boerenerven die zichtbaar zijn op de kadastrale minuutplannen van 1811-1832. Uit nader archiefonderzoek blijkt dat op de scheiding van de twee erven, ter plaatse van de gevonden funderingsresten in 1886 een bakhuis is gebouwd, dat waarschijnlijk dienst deed voor de twee boerderijen. Deze bakhuizen kwamen na 1880 meer in zwang, toen de Brabantse boer meer te besteden had en duurzame bouwmaterialen makkelijker voor handen waren.
De fysieke kwaliteit van de archeologische resten binnen het onderzoeksgebied is laag. De gaafheid van de sporen scoort laag aangezien de resten sterk aangetast zijn. De score voor conservering is middelhoog, er zijn verschillende vondstcategorieën aanwezig. De inhoudelijke kwaliteit van de vindplaats scoort gemiddeld aangezien er vele (ook nog bestaande) contemporaine boerenerven aanwezig zijn.
Het is mogelijk dat er meer resten van de boerenerven (of oudere voorgangers) van de 19e-eeuwse bewoning aanwezig zijn in de directe omgeving van het plangebied. Dit betekent dat de in dit onderzoek aangetroffen sporen onderdeel uit kunnen maken van een groter geheel. Hier dient bij eventuele ontwikkelingen in de omgeving rekening mee gehouden te worden.
