Solving Complex Low Earth Orbit-to-Geostationary Earth Orbit Transfer Problems Using Uniform Trigonometrization Method

open access: yesAerospace
Low-thrust orbit transfer problems are central to reducing mission costs and enabling cleaner, more efficient space travel. However, they remain difficult to solve using mathematically superior indirect methods of optimization.

Neuromarketing research in the last five years: a bibliometric analysis

open access: yesCogent Business & Management, 2021
Neuromarketing (NM) is an application of neuroimaging and physiological tools to record the neural correlates of consumers’ behaviour (e.g., decision-making, emotion, attention, and memory) toward marketing stimuli such as brands and advertisements. This

Programmable Multi‐Axially Aligned Aerogels via Sequential Freeze‐Casting for Tailored Anisotropy and Tunable Mechanics

open access: yesAdvanced Science, EarlyView.
Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.

URANIUM-TITANIUM-METAGEL MINERALIZATION OF AU-U DEPOSITS OF THE ELKON ORE DISTRICT (ALDAN, RUSSIA) AND FEATURES OF ITS PROCESSING

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2016
Large-scale reserves of uranium in Au-U deposits of the Elkon ore district are composed of newly discovered polyphase uranium-titanium metagel (UTM). Before, it was assumed that brannerite is the major mineral of these ores. However, it has been revealed

Study of Compressive Strength by UTM

open access: yes, 2020
Waste reduction techniques are focussed on utilising industrial and agricultural waste. This waste utilisation should not only be economical but also helps in sustainable development. There has been a lot of emphasis on sustainable development over the years with much focus on reduction of environmental impacts and utilization of wastes.

Surface Energy Modulated Self‐Assembly of Percolative Gallium Nanodroplet Films for Stretchable Electronics

open access: yesAdvanced Electronic Materials, EarlyView.
Surface‐energy guided self‐assembly of liquid metals enables the transformation of liquid metal micro/nanodroplets into continuous perocolative films on elastomeric substrates. By tailoring interfacial energetics and wetting behavior, uniform, conductive, and stretchable films are achieved, offering scalable pathways for high‐performance soft ...

Bio‐Inspired Mechanical Amplification Block on Implantable Tactile Sensors

open access: yesAdvanced Electronic Materials, EarlyView.
 . ABSTRACT Implantable strain sensors offer opportunities for continuous biomechanical monitoring, but their performance deteriorates severely once embedded in soft tissue due to mechanical shielding that suppresses strain transmission to the sensing layer.

Lidar‐Based Object Tracking of Traffic Participants with Sensor Nodes in Existing Urban Infrastructure

open access: yesAdvanced Intelligent Systems, EarlyView.
This paper presents a lidar‐based sensor node design and a rule‐based state observer for edge‐based traffic participant tracking. Unlike other state‐of‐the‐art methods, this state observer enables real‐time, CPU‐only edge processing without relying on machine learning approaches.

Design Optimization of Soft Fabric Pneumatic Actuators

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a systematic optimization framework for elongating and bending fabric‐based soft pneumatic actuators. After a preliminary design‐space reduction, the framework minimizes energy consumption under mechanical performance constraints by integrating validated finite element modeling with statistical surrogate models. Optimal designs were
