Prediction of Autonomous Vehicle
Authors: Li Haonan , Wang Xiaolan , Su Xiao , Wang Yansong 
Published: December 2023

Background:
Pedestrian trajectory prediction plays a crucial role in ensuring the safe and
efficient operation of autonomous vehicles in urban environments. As autonomous driving technology
continues to advance, accurate anticipation of pedestrians' motion trajectories has become increasingly
important for informing subsequent decision-making processes. Pedestrians are dynamic and
unpredictable agents, and their movements can vary greatly depending on factors, such as their intentions,
interactions with other pedestrians or vehicles, and the surrounding environment. Therefore,
developing effective methods to predict pedestrian trajectories is essential to enable autonomous vehicles
to navigate and interact with pedestrians in a safe and socially acceptable manner. Various
methods, both patented and non-patented, have been proposed, including physics-based and probability-
based models, to capture the regularities in pedestrian motion and make accurate predictions.

Objective:
This paper proposes a pedestrian trajectory prediction method that combines a Gaussian
mixture model and an artificial potential field.

Methods:
The study begins with an analysis of pedestrian motion patterns, allowing for the identification
of distinct patterns and incorporating speed as an influential factor in pedestrian interactions.
Next, a Gaussian mixture model is utilized to model and train the trajectories of pedestrians within
each motion pattern cluster, effectively capturing their statistical characteristics. The trained model is
then used with a regression algorithm to predict future pedestrian trajectories based on their past positions.
To enhance the accuracy and safety of the predicted trajectories, an artificial potential field
analysis is employed, considering factors such as collision avoidance and interactions with other entities.
By combining the Gaussian mixture model and artificial potential field, this method provides an
innovative and patentable approach to pedestrian trajectory prediction.

Results:
Experimental results on the ETH and UCY datasets demonstrate that the proposed method
combining the Gaussian mixture model and artificial potential field outperforms traditional Linear
and social force models in terms of prediction accuracy. The method effectively improves accuracy
while ensuring collision avoidance.

Conclusion:
The proposed method combining a Gaussian mixture model and an artificial potential
field enhances pedestrian trajectory prediction. It successfully captures the differences between pedestrians
and incorporates speed, improving prediction accuracy.
Error Modeling and Accuracy Analysis of Parallel Robots for Spacecraft
Docking Motion Simulation System
Authors: Yu Dayong 
Published: December 2023

Background::
A large number of on-orbit docking dynamics experiments are conducted in
the spacecraft docking motion simulation system with the development of Chinese space science and
technology, and therefore, the requirement for high-precision parallel robots has increased. The pose
accuracy of parallel robots is one of the most important problems in this application.

Objective::
In order to evaluate the pose accuracy of parallel robots in advance, a comprehensive pose
accuracy analysis method considering major error sources is presented in this paper, and the influence
of major error sources on the pose accuracy is also investigated to summarize the statistics and propagation
characteristics of the pose error.

Methods::
The first-order error model for the parallel robot is established based on a generalized error
model for each hydraulic cylinder and a sensitivity analysis method. Using the error model, a statistical
approach to the parallel robot pose accuracy analysis is presented, and the influence of different parameter
errors and different poses on the pose accuracy of the parallel robot is investigated. Sensitivity analysis
is applied to evaluate the contribution of each parameter error to the position and orientation error of
the parallel robot. An automated pose accuracy analysis program that computes and graphically displays
the position and orientation error distributions and the sensitivity analysis results is developed.

Results:
The statistical analysis results of the influence of different parameter errors and different
poses on pose accuracy are obtained by using the automated pose accuracy analysis program. The
means of the position and orientation errors are close to zero. The standard deviations in the x and y directions are larger than those in the z direction, and these standard deviations are amplified with the
increase of the parameter errors. For the given elevation, sensitivity analysis to various parameter errors
is performed. It is found that the length error sensitivities of the hydraulic cylinders are less than one, and position error sensitivities of the hook joints A4, A5, and A6 are much greater than those of
hook joints A1, A2 and A3.

Conclusion::
The elemental error sources belong to one of two groups, i.e., those affecting the hydraulic
cylinder length and those affecting the hook joints. The distributions of the position and orientation
errors are consistent with statistics theories. The parallel robot is more sensitive to the errors affecting
the hook joints than those affecting the hydraulic cylinder length. These will help the designers and
users of the parallel robot understand the statistics and propagation characteristics of the pose error.
Some recent patents on error modeling and kinematic calibration of parallel robots are also discussed
in this article.

Published: December 2023

Introduction:
Skin is aging external organ protecting the entire body from a complicated process that affects all living things. Vegetable oils give the epidermis a barrier that shields it and halts water loss. Polyunsaturated fatty acids, phenolic and flavonoid content present in grape seed oil (GSO), papaya seed oil (PSO), and flaxseed oil (FSO) are reported for their antioxidant and moisturizing effect when applied as a topical formulation for skin care

Objective:
In the present work, the oils were screened for their antioxidant activity and skin-whitening properties and formulated as nanoemulgel.

Methodology:
The oils studied for their phenolic and flavonoid content and formulated as a nano emulgel using Tween 80 and Transcutol. Further, the formulation was evaluated for its physico-chemical properties and stability.

Results:
The oils' total phenolic and flavonoid content was determined using gallic acid and rutin trihydrate, respectively as standards. The % oleic acid content was determined by using HPTLC where PSO had the highest oleic acid content (54.04%) as compared to GSO and FSO.

Conclusion:
All oils exhibited significant antioxidant activity and tyrosinase enzyme inhibition due to the phenolic components, flavonoids, and tocopherols. Based on the phytoactive present, nanoemulsion in different proportions (3% oil mix and 5% oil mix in a ratio of 1:1:1 and 1.5:1.5:2 for GSO: PSO: FSO) was formulated. Globule size and PDI of the optimized nanoemulsion batch were obtained as 181 nm and 0.292, respectively. Further optimization of formulation and its efficacy and dermatokinetics can be studied.

The Effect of Water Coolant and Bur Type on Pulp Temperature When Removing Tooth Structure and Restorative Dental Materials
Authors: Mafrici C , Kingston M , Grice R , Abbott PV 
Published: December 2023

SUMMARY

Objective
The aim was to compare intrapulp temperature (IPT) changes when flat-fissure diamond burs and pear-shaped tungsten carbide burs were used to cut tooth structure, amalgam, and composite resin with and without water coolant.

Methods
Thermocouples were inserted into the pulp chamber of extracted intact mandibular molars. The thermocouples were connected to an electronic thermometer that detects temperature every second to an accuracy of 0.1°C. IPT changes were recorded while using a high-speed handpiece during MOD cavity preparations (n=40), composite resin removal (n=40), and amalgam removal (n=40). A two-way ANOVA was used for each procedure to test for the effect of bur (pear-shaped tungsten carbide vs flat-fissured diamond) and water coolant (on vs off), with significant main effects (α=0.05) further analyzed using Tukey's multiple comparison test.

Results
During MOD cavity preparation, water coolant reduced changes in IPT (0.03±0.27°C) compared to no water coolant (1.27±0.29°C) when tungsten carbide burs were used (p&lt;0.05) but not when diamond burs were used. During composite resin removal, tungsten carbide burs had less changes in IPT (0.55±0.18°C) compared to diamond burs (1.66±0.50°C) with no water coolant (p&lt;0.05). Water coolant also reduced changes in IPT (0.09±0.14°C) compared to no water coolant (1.66±0.50°C) when diamond burs were used (p&lt;0.01). Water coolant did not significantly affect IPT when tungsten carbide burs were used. During amalgam removal, tungsten carbide burs had lower changes in IPT (0.56±0.15°C) compared to diamond burs (1.88±0.43°C) with no water coolant (p&lt;0.05). Water coolant also significantly reduced changes in IPT (0.71±0.2°C) compared to no water coolant (1.88±0.43°C) when diamond burs were used (p&lt;0.05) but not when tungsten carbide burs were used.

Conclusions
Water coolant reduced IPT changes when drilling tooth structure with tungsten carbide burs, but not when removing amalgam or composite. Conversely, water coolant reduced IPT changes when drilling with flat fissure diamond burs to remove amalgam and composite, but not when removing tooth structure. When amalgam and composite were removed without water coolant, the tungsten carbide burs resulted in lower IPT changes than when flat fissure diamond burs were used in the same way.

Published: December 2023

SUMMARY

Objective
The aim of this investigation was to compare the fracture resistance of chairside computer-aided design and computer-aided manufacturing (CAD/CAM) lithium disilicate–reinforced ceramic occlusal veneers with and without margin and traditional full coverage premolar crowns.

Methods and Materials
A total of 60 chairside CAD/CAM lithium disilicate–reinforced ceramic (Amber Mill, Hass Bio) restorations were designed and fabricated with a chairside CAD/CAM system (CEREC Dentsply Sirona). The restorations were divided into three groups (n=20): 1) occlusal veneer with 1.0-mm uniform occlusal thickness and with chamfer margin; 2) occlusal veneer with 1.0-mm uniform occlusal thickness and without margin; and 3) full coverage crown with uniform occlusal thickness and gingival margin. Occlusal veneers and crowns were cemented with dual cured resin luting cement (Multilink, Ivoclar Vivadent) to printed resin dies, load cycled (5 million load cycles at 1 Hz with 275 N force), and then loaded until fracture. Load at break (LB) and peak load (PL) until fracture were recorded. Scanning electron microscope images of the tested restorations on the abutments were obtained.

Results
Fracture strengths were different depending on the design of the restoration. There was no significant difference in fracture strength between the two types of occlusal veneer (LB: 1132.45 N; PL: 1143.30 N for veneers with margin; LB: 1149.25 N; PL: 1219.05 N for veneers without margin). Full coverage crowns showed the lowest fracture resistance (LB: 936.26 N, PL: 976.42 N), which was significantly lower than both designs of occlusal veneer.

Conclusions
The fracture resistance of the CAD/CAM lithium disilicate–reinforced ceramic restorations was influenced by the design. Occlusal veneers with and without margin displayed higher fracture resistance than traditional crowns.
