Fuzzy Synergetic Control for Dynamic Car-Like Mobile Robot
Authors: Bouhamatou Zoulikha , Abedssemed Foudil
Published: February 2022

This paper aims to present the dynamic control of a Car-like Mobile Robot (CLMR) using Synergetic Control (SC). The SC control is used to make the linear velocity and steering velocity converge to references. Lyapunov synthesis is adopted to assure controlled system stability. To find the optimised parameters of the SC, the grey wolf optimiser (GWO) algorithm is used. These parameters depend on the best-selected fitness function. Four fitness functions are selected for this purpose, which is based on the integral of the error square (ISE), the integral of the square of the time-weighted error (ITSE), the integral of the error absolute (IAE) and the integral of the absolute of the time-weighted error (TIAE) criterion. To go further in the investigation, fuzzy logic type 2 is used to get at each iteration the appropriate controller parameters that give the best performances and robustness. Simulations results are conducted to show the feasibility and efficiency of the proposed control methods.

Perbedaan Persepsi Antara Mahasiswa Pre-Klinik Dan Klinik Terhadap Midline Shifting Pada Gigi Tiruan Lengkap
Authors: Makmur Herry , Adrian Nova
Published: February 2022

Background: Facial aesthetic is affected by components that can be observed from the face as a whole (macro-esthetics), and also from the dental components (micro-esthetics). Ideally, the dental midline of a complete denture should coincide with the facial midline of the wearer (i.e. no midline shifting). Among others, one of the main aims of using complete dentures for prosthodontics treatments is to improve facial aesthetic. Consequently, the ability and competency of a dentist to detect midline shifting is vital in order to attain a complete denture with optimal esthetics. In dentistry, the relationship between individual perception of midline shifting and the level of education is often studied. Apart from gender and age, other factors such as the level of education can influence individual’s perception towards midline shifting. The objective of this study is to find out the difference between the perception of pre-clinical and clinical students towards midline shifting in complete dentures. The type of study is cross-sectional observational analytic. Materials and Methods: This study involves 128 pre-clinical and clinical students in FKG Universitas Trisakti. The student’s perception towards midline shifting is measured using 9 photos and a questionnaire. Results: 128 dental students with equal distribution between pre-clinic and clinic students participated in this study. Data analysis showed difference of perception between the two groups (p-value 0.016). Conclusions: There is a significant difference between the perception of pre-clinical and clinical students  in FKG Universitas Trisakti towards midline shifting in complete dentures.

Perspektif Anatomi Dan Antropometri Pada Senyum
Authors: Anggraini Wita
Published: February 2022

The main muscle that forms a smile is the m.zygomaticus major, which pulls the corners of the mouth to the superior and lateral. The m.zygomaticus major area is related to one's appearance, both when active or inactive. Smiles are fundamentally divided into “spontaneous” or “true” smiles ("Duchenne" smiles) and “fake” smiles or “social” smiles ("non-Duchenne" smiles). In "Duchenne" smile there is an additional contraction of the orbicularis oculi muscle so that the cheeks are raised and form wrinkles around the eyes. The contraction of orbicularis oculi muscle is very difficult to do voluntarily. Clinical smile analysis can be in the form of facial palpation by observing anatomical superficial landmarks of the face. Anthropometric measurements in smile analysis are recommended using standardized photographs with 8 main components of assessment: lip line, smile arch, upper lip curvature, buccal corridors, smile symmetry, occlusal frontal plane, dental components and gingival components. The purpose of this paper is to examine smiles in an anatomical and anthropometric perspective.

In the green storytelling marketing activity, stories about composting activities at home are shown to eradicate the problem of organic waste and promoting product of composting. It is interesting because currently organic waste is the most common type of waste in Indonesia. This research uses a quantitative method for followers of the Instagram account @Sustaination (N=338). Participants are account followers who have purchased composter products and carried out composting activities. An interesting finding in this study is that green storytelling marketing activities can have a direct influence on purchasing decisions for composter products. In addition, the influence of green storytelling marketing can also affect on purchase decision through environmental consciousness. This is because green storytelling marketing can affect the affective, cognitive, and dispositional dimensions of environmental consciousness. In green storytelling marketing, there is information and knowledge conveyed through the stories displayed. This can then help influence the active dimension in which there is an element of purchasing green products. This is the reason green storytelling marketing through environmental consciousness can influence the purchase decision of composter products.

Highly regiospecific, copper salts-free and neat conditions have been demonstrated for the 1,3-dipolar Azide-Alkyne Cycloaddition (AAC) reactions under mechanochemical conditions. A group of structurally challenging alkynes and heterocyclic derivatives was efficiently implemented to achieve highly functionalized 1,4-disubstituted-1,2,3-triazoles in good to excellent yield by using the Cu beads without generation of unwanted byproducts. Furthermore, high-speed ball milling (HSBM) strategy has also been extended to the synthesis of commercially available pharmaceutical agent, Rufinamide, an antiepileptic drug (AED) and its analogues. The same strategy was also applied for the synthesis of Cl-derivative of Rufinamide. Analysis of the single crystal XRD data of the triazole was also performed for the final structural confirmation. The Cu beads can be easily recoverable from the reaction mixture and used for the further reactions without any special treatment.

Published: February 2022

A visible-light driven enantioselective radical addition to imines enabled by the direct excitation of a chiral phosphoric acid-imine complex was developed. By using benzothiazolines as the radical precursors, chiral amine products were obtained with high enantioselectivities (up to 98% ee). Mechanistic studies elucidated that the chiral phosphoric acid-imine complex has photoredox activities for oxidizing benzothiazolines.

We describe that the reduction-cleavable spacer (RCS) containing a nitrobenzene scaffold can be incorporated into a single-stranded DNA sequence to enable the construction of a reduction-responsive DNA architecture with spherical morphology at micrometer scale. The RCS could allow for the introduction of the reduction-responsiveness into various functional oligonucleotides as well as nucleic acid-based architectures.

Published: February 2022

Submerged Arc Welding (SAW) is a safe and efficient process for joining thick plates AISI 1020. A high-quality weld joint is a critical objective in a series of optimization studies. The current study focuses on maximizing the ultimate tensile strength and minimizing the peak temperature using Taguchi, Genetic Algorithm (GA), and Simulated Annealing (SA) algorithms. The input parameters in the three techniques were voltage (V), welding speed (S), and wire feed rate (F). At a 95% confidence level, the regression models were combined using the ANOVA to predict tensile strength and peak temperature. The maximum ultimate tensile strength was 599MPa achieved at a welding speed of 30 mm/s, an arc voltage of 30 V, and a wire feed rate of 120 mm/s, while the minimal peak temperature was 417C under the same conditions. With the increase of the welding parameters (welding speed, arc voltage, and feed rate), the ultimate tensile strength was increased. Furthermore, the average hardness achieved was 250 at welding metal and 292 at HAZ, while it was 275 at the base metal. The results were supported with an examination of microstructure. In the heat-affected zone (HAZ), the grain was finer while its grain size was larger in specimens with high tensile strength. It was noticed that the HAZ contains pearlite and some colonies of ferrite.
