We study the category $\mathcal{C}$ generated by extremal weight modules over $U_q(\mathfrak{gl}_{>0})$. show that is a tensor category, and give an explicit description of socle filtration product any two modules. This follows from Fock space $\mathcal{F}^\infty \otimes \mathcal{M}$ infinite level, which has commuting actions parabolic $q$-boson algebra $U_p(\mathfrak{gl}_{>0})$ with $p=-q^{-1}$. It contains (semisimple) limit fermionic $\mathcal{F}^n$ level $n$, $q$-analogue Howe duality...
A lower-limb exoskeleton robot identifies the wearer′s walking intention and assists movement through mechanical force; thus, it is important to be able identify in real-time. Measurement of angle knee ankle can difficult case patients who cannot move joint properly. Therefore, this study, as well angles talocrural subtalar joints were estimated during by applying neural network two inertial measurement unit (IMU) sensors attached thigh shank. First, for estimation, gyroscope accelerometer...
Solid free-form fabrication (SFF) technology is used to fabricate scaffolds with controllable characteristics including well-defined pore size and porosity. The multi-head deposition system (MHDS), one form of SFF technology, may be more advantageous than others for fabricating because a MHDS does not require the use cytotoxic solvent. This method, however, induce thermal degradation raw materials subsequent decrease in material's molecular weight, whereby hydrolytic degradation, resulting...
Sepsis is a life-threatening condition with high mortality rate. Early prediction and treatment are the most effective strategies for increasing survival rates. This paper proposes neural architecture search (NAS) model to predict onset of sepsis low computational cost performance by applying genetic algorithm (GA). The proposed shares weights all possible connection nodes internally within network. Externally, reduced through weight-sharing effect between genotypes GA. A predictive analysis...
Extended reality (XR) collaboration enables between physical and virtual spaces. Recent XR studies have focused on sharing understanding the overall situation of objects interest (OOIs) its surrounding ambient (AOs) rather than simply recognizing existence OOI. The is achieved using three-dimensional (3D) models that replicate existing in workspace. There are two approaches for creating models: pre-reconstruction real-time reconstruction. approach takes considerable time to create polygon...
In a project-based ETO (Engineering-To-Order) industry, design, purchasing, production and quality processes are closely integrated to meet delivery schedule, cost limitation specification. When an engineering change occurs in project execution stage, miscommunication of design may generate significant delay. This paper suggests model capture share activities for processing done by each stakeholder. The framework also captures ECR (Engineering Change Request), ECO Order) relationship among...
Crystalline silicon single quantum wells (QWs) with a minimum Si layer thickness of around 1nm were fabricated by high temperature thermal oxidation separation implantation oxygen (SIMOX) and epitaxial transfer (ELTRAN®) silicon-on-insulator (SOI) wafers. Not only but also defect-free SOI materials may be important factors for observation quantum-confined transition in the QWs. QWs from SIMOX wafers showed strong interface-mediated luminescence, which is independent thickness, at 1.63 1.49eV...
Solar cell is device that directly converts the energy of solar radiation to electrical energy. So it important for reduce surface reflection light in order improve efficiency device. Texturing and antireflection coating have been used light. technology has reduced 10% incident However, there are a few disadvantages random pyramid texturing results not always reproducible an industrial environment. And AR (MgF 2 , ZnS) difficult apply standard process because high vacuum needed expense very...
This study addresses the challenges that conventional network models face in detecting small foreign objects on industrial production lines, exemplified by scenarios where a single piece of iron filing occupies approximately 0.002% image area. To tackle this, we introduce an enhanced YOLOv8-MeY model for surface sugar bags. Firstly, introduction 160 × 160-scale object detection layer and integration Global Attention Mechanism (GAM) attention module into feature fusion (Neck) increased...
Virtual Reality (VR) and Augmented (AR) have become familiar technologies with related markets growing rapidly every year. Moreover, the idea of considering VR AR as one eXtended reality (XR) has broken border between virtual space real space. However, there is no formal way to create such XR content except through existing or development platforms. These platforms require author perform additional tasks duplicating for a specific user interaction environment (VR AR) associating them one....
In this paper, we derive the exact probability distribution of post-scheduling signal-to-interference-plus-noise ratio (SINR) considering both user feedback and scheduling. We also develop an optimized adaptive modulation scheme in orthogonal random beamforming systems with M transmit antennas K single-antenna users. The distributions each user's SINR postscheduling are derived rigorously by direct integration multinomial distribution. It is shown that cumulative function (CDF) happens to be...
Reduction of optical losses in crystalline silicon solar cells by surface modification is one the most important issues photovoltaics. Porous Si layers on front textured substrates have been investigated with aim improving cells, because an anti-reflection coating and a passivation can be obtained simultaneously process. We demonstrated feasibility very efficient porous AR layer, prepared simple, cost effective, electrochemical etching method. Silicon p-type CZ (100) oriented wafers were...
