Conceptual design of single-stage launch vehicle with hybrid rocket engine using design informatics

Nihon Kikai Gakkai ronbunshu, 2014
A single-stage launch vehicle with hybrid rocket engine has been conceptually designed by using design informatics, which has three points of view, i.e., problem definition, optimization, and data mining.

The Mysterious Stranger and Modern Enchantment

The British Journal of Sociology, EarlyView.
ABSTRACT Sociological accounts of modernity have long emphasized rationalization, alienation, and the attenuation of affective intensity. While these diagnoses capture crucial dynamics of modern social order, they leave underexplored a persistent and generative dimension of social life: enchantment.

Collaborative Sounding Rocket launch in Alaska and Development of Hybrid Rockets

TRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, SPACE TECHNOLOGY JAPAN, 2009
Tokai University student rocket project (TSRP) was established in 1995 for a purpose of the space science and engineering hands-on education, consisting of two space programs; the one is sounding rocket experiment collaboration with University of Alaska Fairbanks and the other is development and launch of small hybrid rockets.

Region‐of‐interest geometry optimization for shooting‐distance estimation from flash‐pulse infrared thermography of gunshot residue on textile targets

Journal of Forensic Sciences, EarlyView.
Abstract Shooting‐distance estimation from gunshot‐residue (GSR) patterns on textiles is affected by substrate properties, residue distribution, and region‐of‐interest (ROI) definition. This study evaluated how ROI geometry influences muzzle‐to‐target distance regression from flash‐pulse infrared thermography of GSR‐related thermal patterns.

On the Conceptual Overstretch of Weaponized Interdependence in Lithium and Rare‐Earth Element Markets

Global Policy, EarlyView.
ABSTRACT This paper critically examines the conceptual overstretch of weaponized interdependence (WI) in analyses of China's dominance over lithium and rare‐earth element (REE) markets. Although WI has become a central framework for interpreting EU–China economic relations, its application to raw materials often extends beyond the theory's original ...

Re‐thinking peripheral dysfunctions in obesity: The emerging role of sulphaceutics and sulphanutraceutics

British Journal of Pharmacology, EarlyView.
Obesity is a chronic, relapsing, multisystem disease in which cardiometabolic risk arises from excess adiposity and progressive dysfunction of peripheral organs, ultimately disrupting endocrine and metabolic crosstalk among tissues. Within this network, sulphur‐based biology, centred on hydrogen sulphide and related reactive sulphur species, has ...
