This interdisciplinary research integrates theoretical principles like Betz's law, Bernoulli's principle, and Navier-Stokes equations that helps in CFD (Computational Fluid Dynamics) simulations to design an efficient pinwheel type wind turbine. Through the use of CFD analysis, 7 different types of pinwheel blade designs are evaluated, and among them the most efficient one is chosen with an efficiency improvement of 51.4% over the previous one which performance coefficient was 49% for the given wind speed at 5ms-1 • The key engineering complexity involved designing a control system using an array of 8 hall-effect sensors at 45° intervals for 360° wind direction detection and blade orientation adjustment. Recognizing real-world challenges, a prototype is developed incorporating hall-effect sensors together with a magnetic pointer for dynamic blade positioning based on wind direction within the angle intervals that results in the maximum voltage and power outputs of approximately 4V and 2.66W respectively after testing. Despite having the lack of market constraints limits for the applicability of this research, this paper is aimed at surpassing the current power efficiency benchmarks and, therefore, becoming a prototype that remains valuable from the point of view of discovering new knowledge and innovations in methodology. © 2024 IEEE.

Patient monitoring and continuous updation of their health status is very serious concern especially during the times of pandemic like situations. Since, it is a costly affair with heavy instruments and hosptialization of every patient in India is very expensive for moderate earning citizens and ever increasing population of India also leads to lack of hopspital bed availability. Also, in remote areas the hospitals are at very distant locations from their stay. In order to overcome these challenges, we have proposed an economic and efficient utilization of IOT based sensors and a mobile application to continuously monitor affected patient’s data from their locations and with the usage of mobile app, continuous health reports can be provided to doctors. So, three IOT sensors namely ECG, which monitors heart rate, DHT-11 to measure temperature and humidity of patient surroundings and MQ-2 to monitor gas levels of patient’s surroundings. The patient will attach these sensors on their arm which will enable to provide the readings of patient’s health. Now, the readings fetched using these IOT sensors are stored and converted in the form of medical report using wireless Blynk mobile application. This wireless Blynk mobile application database is synced with a cloud platform through which the patient’s report will be sent to doctor’s Blynk mobile application. In this manner, the continuous monitoring of patient’s health will be ensured and this application makes it easier and more convenient to share health reports by users. Through fair analysis and justification from our results, the proposed work will showcase our usage of IOT based sensors which will effectively help to continuously monitor the patient’s health. © 2024 IEEE.

Label assignment refers to determining positive/negative labels foreach sample to supervise the training process. Existing Siamese-based trackersprimarily use fixed label assignment strategies according to human priorknowledge;thus, they can be sensitive to predefined hyperparameters and failto fit the spatial and scale variations of samples. In this study, we first developa novel dynamic label assignment (DLA) module to handle the diverse datadistributions and adaptively distinguish the foreground from the backgroundbased on the statistical characteristics of the target in visual object *** core of DLA module is a two-step selection mechanism. The first stepselects candidate samples according to the Euclidean distance between trainingsamples and ground truth, and the second step selects positive/negativesamples based on the mean and standard deviation of candidate *** proposed approach is general-purpose and can be easily integrated intoanchor-based and anchor-free trackers for optimal sample-label *** to extensive experimental findings, Siamese-based trackers withDLA modules can refine target locations and outperformbaseline trackers onOTB100, VOT2019, UAV123 and LaSOT. Particularly, DLA-SiamRPN++improves SiamRPN++ by 1% AUC and DLA-SiamCAR improves Siam-CAR by 2.5% AUC on OTB100. Furthermore, hyper-parameters analysisexperiments show that DLA module hardly increases spatio-temporal complexity,the proposed approach maintains the same speed as the originaltracker without additional overhead.

Fused deposition modeling (FDM) is the first 3D printing technique that most people and consumers are getting introduced. Globally, 3D printing with the FDM method is most often used with 3D printers. Among the seven primary various additive manufacturing techniques, usually preferred material extrusion technology is FDM or Fused Filament Fabrication (FFF). In the FDM technique, a continuous thermoplastic or composite material thread is employed to make 3D components. Plastic filament is fed through an extruder, melted at the extruding nozzle, and then deposited layer by layer onto the build platform automatically according to the part structure. In the investigation of process parameters, the specimens are made of PLA (polylactic acid) material. With Taguchi method, the design of the experiments is prepared, and the specimens are created. There are nine specimens made with different parameters, namely the nozzle temperature, infill pattern, and layer thickness. ANOVA analysis is employed to identify the optimum process parameters in FDM process. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Stability, desired locomotion position, and orientation are crucial in the control of bipedal robots. This paper focuses on the design and analysis of a bipedal robot with a curved knee link versus a linear knee link robot. It also focuses on its own weight balance while moving from one position to another and changing joint angles without falling. This modified design is also compared with the NAO humanoid robot in real-time. The final bipedal robot model mentioned in this paper is a biped robot with 12 degrees of freedom, with two legs coaxially connected to the hip region. The robot stands about 26 cm tall and weighs about 580 g. The design is symmetric to keep the robot’s center of mass under the lower limb region. Each leg has six degrees of freedom (DOF), which are controlled by an open-loop system. Robots have undergone various design iterations for analysis. The main aim of this analysis work is to examine and compare a suitable link design that provides a stable walk for a bipedal robot. The experimental results show that the curvy link with a biomimetic design is more stable. Compared to a linear-linked robot, the biomimetic bipedal design moves and balances its weight effectively during mobility. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

In modern digital design, energy efficiency is a major concern, especially for low-power applications. This paper investigates ways to reduce the power consumption of Level Triggered D-Flip-Flops (LT-DFFs) generated by the application of clock and power-gating techniques. Clock gates selectively disable clock signals in registers when their operation is not necessary, thereby reducing dynamic power consumption. On the other hand, the power strip completely isolates the circuit sections by disconnecting the power supply during the inactive period, minimizing leakage currents. This study explores the simulation and implementation of these technologies with industry standard design tools, evaluates their power reduction effectiveness, and maintains time and functional requirements. The experimental results show significant energy savings in the LT-DFF without compromising performance, highlighting the potential of time-saving and energy-saving strategies to improve energy efficiency of digital circuits. The Proposed Design - I and II demonstrate significant reduction in switching power, achieving a 40 % improvement when the input switches every 4 clock cycles or longer. All designs are operated at an operating frequency of 1 G Hz and input switches with a switching factor (α) of 0.33. © 2024 IEEE.

Poroelastic modelling of brain tissue swelling and decompressive craniectomy treatment in ischaemic stroke

引用

Computer Methods in Biomechanics and Biomedical engineering 2024年 1-11页

作者： Nadzri, Aina Najwa Nik Mohamed, Nik Abdullah Payne, Stephen J.

Brain oedema or tissue swelling that develops after ischaemic stroke can cause detrimental effects, including brain herniation and increased intracranial pressure (ICP). These effects can be reduced by performing a decompressive craniectomy (DC) operation, in which a portion of the skull is removed to allow swollen brain tissue to expand outside the skull. In this study, a poroelastic model is used to investigate the effect of brain ischaemic infarct size and location on the severity of brain tissue swelling. Furthermore, the model will also be used to evaluate the effectiveness of DC surgery as a treatment for brain tissue swelling after ischaemia. The poroelastic model consists of two equations: one describing the elasticity of the brain tissue and the other describing the changes in the interstitial tissue pressure. The model is applied on an idealized brain geometry, and it is found that infarcts with radius larger than approximately 14 mm and located near the lateral ventricle produce worse brain midline shift, measured through lateral ventricle compression. Furthermore, the model is also able to show the positive effect of DC treatment in reducing the brain midline shift by allowing part of the brain tissue to expand through the skull opening. However, the model does not show a decrease in the interstitial pressure during DC treatment. Further improvement and validation could enhance the capability of the proposed poroelastic model in predicting the occurrence of brain tissue swelling and DC treatment post ischaemia. © 2024 Informa UK Limited, trading as Taylor & Francis Group.
