Improving Turn Movement Count Using Cooperative Feedback.

In this paper, we propose a new cooperative method that improves the accuracy of Turn Movement Count (TMC) under challenging conditions by introducing contextual observations from the surrounding areas. The proposed method focuses on the correct identification of the movements in conditions where current methods have difficulties. Existing vision-based TMC systems are limited under heavy traffic conditions. The main problems for most existing methods are occlusions between vehicles that prevent the correct detection and tracking of the vehicles through the entire intersection and the assessment of the vehicle's entry and exit points, incorrectly assigning the movement. The proposed method intends to overcome this incapability by sharing information with other observation systems located at neighboring intersections. Shared information is used in a cooperative scheme to infer the missing data, thereby improving the assessment that would otherwise not be counted or miscounted. Experimental evaluation of the system shows a clear improvement over related reference methods.

IMPLEMENTASI PENGGUNAAN METODE SHARED STORAGE DALAM PERBAIKAN TATA LETAK PENYIMPANAN MOLD DI PT DYNAPLAST CIBITUNG

In the development of industry and technology, warehouse layout issues have become crucial in manufacturing industries, including PT Dynaplast Cibitung, which specializes in plastic injection production using molds. The current placement of molds in the storage warehouse is suboptimal and hinders identification during the transfer to the machines. This research aims to improve the mold storage layout for better organization and easier identification during machine transfers. It adopts the shared storage method, prioritizing the storage of fast-moving items closest to the entry and exit points. Molds are classified into fast-moving, medium-moving, and slow-moving categories, with fast-moving molds placed nearest to the entry and exit points. Furthermore, mold placement also considers the distance to the machines to minimize transfer distances.

A dynamic price jump exit and re-entry strategy for intraday trading algorithms based on market volatility

Trading algorithms adopt automated risk management systems in order to mitigate against market risk and extreme market events. These systems are aimed at reducing potential losses due to unforeseen market events caused by a plethora of extraneous factors. One such unforeseen event is a price jump, a somewhat vaguely defined but abrupt change in asset price. In this paper, we propose a novel exit and re-entry strategy (suitable for intraday trading algorithms) capable of identifying market exit points, triggered by price jumps, and thereafter monitoring market stability conditions until an appropriate point of market re-entry has been identified. Validation results indicate that the proposed exit and re-entry strategy provides a new perspective on identifying points/intervals of price jump when compared with existing price jump identification methods and the opinion of a subject matter expert.

TRAUMATISME CERVICO-FACIAL PAR BARRE DE FER : A PROPOS DE DEUX CAS PEDIATRIQUES

objective: Head and neck trauma is common in ENT emergencies. The severity depends on the area of impact, the causal object and the injuries caused. We report two cases of head and neck trauma secondary to an iron bar caused by a playful accident.observation 1: 12-year-old boy received for penetrating neck wound with an iron bar, affecting sectors 2 and 3 with entry point at the left subdigastric region and exit point at the ipsilateral mastoid region. The exploratory cervicotomy did not find any major vascular lesions and allowed the extraction of the blunt object. The postoperative course was simple.observation 2: 8-year-old girl received for trauma to the mandible by a transfixing iron bar. The exploration revealed an iron bar which crossed the submental region with an exit point at the level of the floor of the mouth. The extraction was carried out without major vasculo-nervous lesions. The postoperative course was simple.Conclusion: Head and neck trauma remains a concern due to its potential seriousness and remains a medical-surgical emergency. The management of such a case must be preceded by a lesion diagnosis in order to prevent surgical surprises. Exploratory cervicotomy allows good exposure of the vascular-nervous structures. Prevention through parent education and child monitoring is essential to reduce the incidence of these injuries.

On the Creation, Depletion, and End of Life of Polar Cap Patches

AbstractIonospheric convection patterns from the Super Dual Auroral Radar Network are used to determine the trajectories, transit times, and decay rates of three polar cap patches from their creation in the dayside polar cap ionosphere to their end of life on the nightside. The first two polar cap patches were created within 12 min of each other and traveled through the dayside convection throat, before entering the nightside auroral oval after 104 and 92 min, respectively. When the patches approached the nightside auroral oval, an intensification in the poleward auroral boundary occurred close to their exit point, followed by a decrease in the transit velocity. The last patch (patch 3) decayed completely within the polar cap and had a lifetime of only 78 min. After a change in drift direction, patch 3 had a radar backscatter power half‐life of 4.23 min, which reduced to 1.80 min after a stagnation, indicating a variable decay rate. 28 minutes after the change in direction, and 16 min after coming to a halt within the Clyde River radar field‐of‐view, patch 3 appeared to reach its end of life. We relate this rapid decay to increased frictional heating, which speeds up the recombination rate. Therefore, we suggest that the slowed patch motion within the polar cap convection pattern is a major factor in determining whether the patch survives as a recognizable density enhancement by the time the flux tubes comprising the initial patch cross into the nightside auroral oval.

Forex market directional trends forecasting with Bidirectional-LSTM and enhanced DeepSense network using all member-based optimizer

This study focuses on successful Forex trading by emphasizing the importance of identifying market trends and utilizing trend analysis for informed decision-making. The authors collected low-correlated currency pair datasets to mitigate multicollinearity risk. Authors developed a two-stage predictive model that combines regression and classification tasks, using the predicted closing price to determine entry and exit points. The model incorporates Bi-directional long short-term memory (Bi-LSTM) for improved price forecasting and higher highs and lower lows (HHs-HLs and LHs-LLs) to identify trend changes. They proposed an enhanced DeepSense network (DSN) with all member-based optimization (AMBO-DSN) to optimize decision variables of DSN. The performance of the models was compared to various machine learning, deep learning, and statistical approaches including support vector regressor (SVR), artificial neural network (ANN), auto-regressive integrated moving average (ARIMA), vanilla-LSTM (V-LSTM), and recurrent neural network (RNN). The optimized form of DSN using genetic algorithm (GA), particle swarm optimization (PSO), and differential evolution (DE) was compared with AMBO-DSN, yielding satisfactory results that demonstrated comparable quality to the observed trends on the original currency pairs. The effectiveness and reliability of the AMBO-DSN approach in forecasting trends for USD/EUR, AUD/JPY, and CHF/INR currency pairs were validated through statistical analysis while considering computational cost.

Optimisation of the blood supply at the flap donor site through the application of cutaneous negative pressure

At present, perforator flaps are a very popular technique in reconstructive surgery. However, in spite of the fact that perforator flaps provide favourable aesthetic results, their use is often related to complications in the form of transplanted tissue perfusion disorders.
 Objective — to investigate the possibility of optimising the blood supply at the flap donor site through the application of cutaneous negative pressure (NP).
 Materials and methods. The study was carried out from 2019 to 2021. A single‑arm clinical trial consisted of 20 individuals who presented with deep wound defects requiring flap coverage. A dynamic thermography study was conducted to examine the chosen donor site before and after dressing with NP.
 Results. The temperature measurements obtained from the two selected warm perforator points and the point in the cool area between perforators prior to the application of NP showed a steady downward trend in temperature. Specifically, the temperature in the cool area was observed to be lower by an average of –1.89 °С and –2.12 °С as compared to warm points. The application of local NP had an impact on trend analysis of skin temperature, which demonstrated a significant decrease in the differences between values seen in the cool and warm areas. This effect was already noted after the first day of the NP system application, as evidenced by the everyday data collection. The «levelling» of temperature curves was associated with temperature rises both in the cool area and at the perforator exit points.
 Conclusions. The findings obtained from thermography analysis suggest that the application of NP has the potential to enhance blood circulation in the intended donor area. Therefore, it is plausible to discuss the possibility of improved microcirculation in the skin and the beneficial effect of local cutaneous NP application on the state of anastomoses between perforators.

Dynamic responses of kerosene-filled riveted tanks subjected to hydrodynamic ram caused by ballistic impacts

The hydrodynamic ram (HRAM) is a hydrodynamic pressure phenomenon that occurs when high-speed projectiles impact a liquid-filled tank. During combat missions, aircraft are prone to HRAMs caused by projectile impacts, which can damage the structural integrity of riveted tanks, posing a threat to flight safety. In this study, kerosene-filled riveted tanks were chosen as the research object. The dynamic response histories of the rear panel were observed using the three-dimensional digital image correlation (3D-DIC) technique. Additionally, numerical simulations of the projectile's impact on the tank were performed using the fluid–structure interaction finite element method. The simulation results had a good fit with the experimental results. The spatial and temporal distribution of the HRAM and the effect of the projectile impact velocity on the deformation of the tank structure were further analyzed. The impulse exerted by the drag wave on the rear panel was greater than that of the pioneer wave. However, the drag wave's region was limited to a radius of 6 cm around the exit point with the impact velocity range of the projectile of 955 m·s−1–1607 m·s−1 in both the experiments and simulations. When the impact velocity of the projectile reached 955 m·s−1, radial plastic hinge lines appeared on the rear panel along the diagonal direction. When the impact velocity increased to 1607 m·s−1, radial plastic hinge lines along the diagonal direction, and traveling plastic hinges at the root of the central cross-shaped cracks appeared on the rear panel, accompanied by a petal-shaped hole. Based on the spatial distribution of the impulse on the rear panel, a dimensional relationship was established between the hole size and the impulse on the rear panel. The petal model for describing petal-shaped cracks was proposed based on the law of conservation of energy, which could predict the hole size in the case of projectile impact at high velocity. The research results are of great significance for the study of the damage of riveted tanks with HRAMs and provide support for the vulnerability analysis of aircraft tanks.

TRANSCORACOID DRILLING FOR CORACOCLAVICULAR LIGAMENT RECONSTRUCTIONS IN PATIENTS WITH ACROMIOCLAVICULAR JOINT DISLOCATIONS RESULT IN ECCENTRIC TUNNELS

This study aimed to describe the morphology of the coracoid process and determine the frequency of commonly observed patterns. The second purpose was to determine the location of inferior tunnel exit with superior based tunnel drilling and the superior tunnel exit with inferior based tunnel drilling.A sample of 100 dry scapulae for the morphology aspect and 52 cadaveric embalmed shoulders for tunnel drilling were used. The coracoid process was described qualitatively and categorized into 6 different shapes. A transcoracoid tunnel was drilled at the centre of the base. Twenty-six shoulders were used for the superior-inferior tunnel drilling approach and 26 for the inferior-superior tunnel drilling approach. The distances to the margins of the coracoid process, from both the entry and exit points of the tunnel, were measured.Eight coracoid processes were of convex shape, 31 of hooked shape, 18 of irregular shape, 18 of narrow shape, 25 of straight shape, and 13 of wide shape. The mean difference for the distances between superior entry and inferior exit from the apex was Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation 3.65+3.51mm (p=0.002); 1.57+2.27mm for the lateral border (p=0.40) and 5.53+3.45mm for the medial border (p=0.001). The mean difference for the distances between inferior entry and superior exit from the apex was 16.95+3.11mm (p=0.0001); 6.51+3.2mm for the lateral border (p=0.40) and 1.03+2.32 mm for the medial border (p=0.045).The most common coracoid process shape observed was a hooked pattern. Both superior to inferior and inferior to superior tunnel drilling directed the tunnel from a more anterior and medial entry to a posterior-lateral exit. Superior to inferior drilling resulted in a more posteriorly angled tunnel. With inferior to superior tunnel drilling cortical breaks were observed at the inferior and medial margin of the tunnel.

Juridical analysis of entry and exit points for animal and plant quarantine carrier media

Purpose: The purpose of this study was to determine the legal arrangements for the place of entry and release of animal and plant quarantine carrier media, and the factors, constraints, solutions, and implementation of the place of entry and release of animal and plant quarantine carrier media.
 Methodology: The research method of this thesis is normative juridical (legal research) through a literature study with an empirical juridical approach (sociological juridical) through field studies aimed at empirically obtaining legal knowledge.
 Results: The results showed that the legal regulation of the place of entry and release of animal and plant quarantine carrier media is Article 86 and Article 87 of Law Number 21 of 2019 concerning Animal, Fish and Plant Quarantine, which regulates the prohibition of entering or removing animal and plant quarantine carrier media other than the place of entry and release determined by the Central Government. The implementation of animal and plant quarantine entry and exit points at the Batam Class I Agricultural Quarantine Center reflects serious efforts to maintain the integrity of the national biological security. However, there are obstacles, such as limited human resources, inadequate facilities, and challenges in inter-stakeholder coordination. However, by applying the latest technology, increasing the capacity of human resources through training, and improving coordination and communication with related parties, the Batam Quarantine Center found a strategic solution to improve the efficiency and effectiveness of its services in carrying out quarantine duties.

How intramyocardial fat can alter the electric field distribution during Pulsed Field Ablation (PFA): Qualitative findings from computer modeling.

Even though the preliminary experimental data suggests that cardiac Pulsed Field Ablation (PFA) could be superior to radiofrequency ablation (RFA) in terms of being able to ablate the viable myocardium separated from the catheter by collagen and fat, as yet there is no formal physical-based analysis that describes the process by which fat can affect the electric field distribution. Our objective was thus to determine the electrical impact of intramyocardial fat during PFA by means of computer modeling. Computer models were built considering a PFA 3.5-mm blunt-tip catheter in contact with a 7-mm ventricular wall (with and without a scar) and a 2-mm epicardial fat layer. High voltage was set to obtain delivered currents of 19, 22 and 25 A. An electric field value of 1000 V/cm was considered as the lethal threshold. We found that the presence of fibrotic tissue in the scar seems to have a similar impact on the electric field distribution and lesion size to that of healthy myocardium only. However, intramyocardial fat considerably alters the electrical field distribution and the resulting lesion shape. The electric field tends to peak in zones with fat, even away from the ablation electrode, so that 'cold points' (i.e. low electric fields) appear around the fat at the current entry and exit points, while 'hot points' (high electric fields) occur in the lateral areas of the fat zones. The results show that intramyocardial fat can alter the electric field distribution and lesion size during PFA due to its much lower electrical conductivity than that of myocardium and fibrotic tissue.

Hybrid Transcranial Magnetic Stimulation and Deep Brain Stimulation in the Presence of an Implantable Pulse Generator

Transcranial Magnetic Stimulation (TMS) has been shown to improve speech impairment in Parkinson’s Disease (PD) patients. Most PD patients undergo Deep Brain Stimulation (DBS) implantation to improve their motor function prior to the development of speech impairment. Therefore the potential for TMS treatment must take into account the DBS probes’ high conductivity, potentially causing excess stimulation. Prior research regarding this phenomenon is highly conflicting and needs investigation. This study reports electromagnetic interference using a highly accurate finite element analysis approach to determine the electric field distribution in patients with DBS probes undergoing TMS therapy. Additionally, we tested various coil orientations and coil models to fully examine the extent that TMS affects DBS. We considered accurate DBS geometry by creating high-resolution models of Medtronic 3389 DBS, including an Implantable Pulse Generator (IPG) and multiple loops at the exit point of the cranium, which previous studies lack. By studying the induced current in the DBS leads, we determined that the combination of TMS and DBS varies in safety relative to its coil orientation and coil type. Specifically, the quadruple butterfly coil (QBC) targeted at the lateral motor cortex did not induce unsafe levels of currents in the DBS leads even at 100% of the maximum stimulator output.

Augmented Reality Based Indoor Navigation System

Abstract: Every people, at some point in their life, may get lost inside a large auditorium, struggled to find their exit point at the airport, or may get late to a lecture because they could not find the right lecture hall at the university. This paper addresses the development of an Augmented Reality Based Indoor Navigation Application. It is based on four main modules, 3D model building, shortest path calculation, QR code scanning and path visualization. The application is developed in Unity using AR Core XR plugin management and AR Foundation plugin. ZXing library is used for scanning and decoding the QR codes. We aim at developing the front end in the simplest way possible so that the users can easily reach their destination by just opening the camera where the directions are shown as animations in their surroundings.

Achieving Sustainable Coastal Environment by Examining Destination Image and Tourists’ Environment Responsible Behavior

The irresponsible actions of tourists harm the coastal environment. Throwing garbage in the water, damaging green belts and lawns, and throwing disposable material and shopping bags harm the environment and beautification of coastal destinations. Previous researchers have identified the worse effect of tourists’ irresponsible behaviors on the environment and the aquatic ecosystem of coastal destinations. Concern for the coastal destination environment has pushed researchers and destination management officers to identify the underlying behavioral patterns of tourists and proposed strategies for influencing tourists’ environment responsible behavior (ERB). Current research has discussed the significance of destination image in shaping tourists’ ERB with the help of the cognitive???affective???conative destination image (DI) model. Further study has discussed the mediating effect of perceived destination trust (PDT) and the moderating role of perceived destination reputation (PDR) in shaping tourists’ ERB with the theoretical lens of signaling theory. A self-administrative survey research design was employed, and 954 completed questionnaires were used for data analysis. Data were gathered from the tourists attending coastal destinations located in Karachi, a city in Pakistan. Sitting arrangements for the data collection were made at the exit points of each beach. The study used three categories of hypothesized relationships: direct, mediation, and moderation. The findings of the study indicated that cognitive image has an insignificant effect on the tourists’ ERB while having a significant effect on the affective image and conative image. Results for affective DI show significant effect on conative DI and tourists’ ERB. Further results for conative image showed a significant effect on ERB. Results for mediation showed significant meditation of PDT among the DI and ERB. Finally, the results for PDR showed significant moderation and further indicated that a high level of PDR raises the level of tourists’ ERB. In contrast, tourists showed a low level of ERB when they had a low perception of the destination's reputation. The study has made unique efforts to understand the complex tourists’ ERB with the help of the cognitive???affective???conative image model and signaling theory.

Experimental Study of the Surface Quality of Form-Cutting Tools Manufactured via Wire Electrical Discharge Machining Using Different Process Parameters.

Form-cutting tools are an economical choice for turning parts with defined profiles in mass production. The effects of the form contour of these tools-produced by the wire electrical discharge machining (WEDM) process-on tool quality were investigated in this research. This study focuses on reducing the adverse effects of the recast layer induced by WEDM on form-cutting tools. The basic component types of profile forms in form-cutting tools can be summarized by a combination of four modes, i.e., concave and convex arcs and flat and oblique surfaces. Hence, sample cutting tools with three different radii of convex and concave arcs and a flat surface were produced. During the WEDM operation, one-pass mode was used for roughing, two passes for semi-finishing, and three passes for finishing. Furthermore, the difference between the percentage of oxygen and carbon elements on the recast layer in the two areas above the workpiece or wire entry point and the bottom area of the workpiece or wire exit point was investigated. Finally, the influences of the direction, size of the curvature, and the number of passes in the wire electric discharge process on the recast layer were analyzed. It was observed that the recast layer thickness could be reduced by increasing the number of WEDM process. Additionally, the uniformity of the cutting contour was superior in the entry region of the wire going into the workpiece compared with the exit region of the wire.

Facilitation of visual adaptation to glare control for daytime fire evacuation from an office building in Malaysia

This paper proposes that the light intensities of adjacent interior spaces should be concurrently evaluated to reduce the risk of glare when evacuees transition between spaces to reach the final exit. The prevention of glare during daytime evacuation has the potential to smoothen the evacuation process from a building. As all legislative, regulatory, and assessment tool recommendations currently used in Malaysia measure illuminance (in lux), this paper similarly evaluates illuminance instead of luminance for ease of initial adoption in the country. Illuminance recommendations in MS1525:2019, LEED, DOSH Guidelines, UBBL, GBI, GreenRE, Melaka Green Seal, and MyCREST were compared to determine the contrast ratio. The illuminance contrast is greatest at the final exit points, such as from parking structures, lobbies, and staircases, which are benchmarked against the Malaysian sky illuminance that can reach 100,000 lux. A contrast ratio as high as 2000:1 may occur if Malaysian offices were designed to only achieve the minimum illuminance requirements. Of the three assessed final exit spaces, naturally-lit fire escape staircases were selected for modelled simulation of illuminance performance using VELUX Daylight Visualiser 2. The findings ascertained that most typical staircase layouts are able to exceed the minimum illuminance requirements at noon, when the sun is potentially the most intense, although the contrast ratio may still reach 1480:1. While the contrast between intermediate spaces are acceptable, those between the final exit transitions and the outdoors are high, suggesting a risk of glare. Further studies are required to determine strategies to facilitate visual adaptation for Malaysians, such as the identification of an ideal acceptable illuminance contrast ratio, temporal adaptation period, or distance-based parameters.

Glial plasticity at nervous system transition zones.

The central and peripheral nervous systems (CNS and PNS, respectively) are two separate yet connected domains characterized by molecularly distinct cellular components that communicate via specialized structures called transition zones to allow information to travel from the CNS to the periphery, and vice versa. Until recently, nervous system transition zones were thought to be selectively permeable only to axons, and the establishment of the territories occupied by glial cells at these complex regions remained poorly described and not well understood. Recent work now demonstrates that transition zones are occupied by dynamic glial cells and are precisely regulated over the course of nervous system development. This review highlights recent work on glial cell migration in and out of the spinal cord, at motor exit point (MEP) and dorsal root entry zone (DREZ) transition zones, in the physiological and diseased nervous systems. These cells include myelinating glia (oligodendrocyte lineage cells, Schwann cells and motor exit point glia), exit glia, perineurial cells that form the perineurium along spinal nerves, as well as professional and non-professional phagocytes (microglia and neural crest cells).

AN INTEGRATED GEOTECHNICAL INVESTIGATION FOR STRUCTURAL FOUNDATION SUITABILITY ACROSS NIGER RIVER, NORTH CENTRAL NIGERIA

- The need to assess the suitability of foundation soil for oil and gas installations, such as pipeline, stations, and all other ancillary facilities, necessitated this study across the Niger River of north central Nigeria. A total of 17 boreholes and cone penetration tests were conducted. Samples were recovered from the boreholes and tested in the laboratory to obtain soil parameters. The investigation revealed that the subsurface is essentially composed of FINE SAND/SAND and CLAY. The FINE SAND is largely the superficial soil except in BH1 where CLAY is the superficial soil. The FINE SAND is loose at the top becoming medium dense and clayey at the base as it grades into CLAY. It has a greyish colour, with moisture content between 6% and 29% and bulk unit weight between 15.17 kN/m3 and 21.76 kN/m3 . The CLAY underlies the FINE/SAND and SAND. It is generally greyish in colour, with moisture content between 12% and 29% and bulk unit weight between 15.17 kN/m3 and 21.30 kN/m3 and an average strength of 156 kN/m2 except where it is the surficial soil and soft (strength < 25 kN/m2 ). Oversize materials were not encountered during the investigation and as such shall not pose any risk to horizontal directional drilling operation. However, on the Island, within the FINE SAND, bed of gravel occurs in BH8 and BH9. In terms of plasticity, due to saturation, the soils are not expected to swell. Nevertheless, it is advisable to add polymers to the drilling mud to prevent transfer of water from the drilling fluid into the soil as a precaution for clayey soils at the entry and exit points and on the Island. Most of the soil contains fines less than 30% and therefore, specific measures may be employed to improve borehole stability during drilling and installation.
