AbstractFor aircraft noise calculations, lateral flight dispersion is commonly represented by means of subtracks – a backbone track and side-tracks to each side of the backbone track – where each subtrack is assigned a movement percentage. Aircraft noise calculations impose quality demands on these subtracks, while the latter are often created based on limited information.This paper presents a method to increase flexibility when designing subtracks. The method allows to redistribute subtracks geometrically, allowing for the design of simplified track representations, for instance through a lower number of subtracks and very basic indications of movement allocations. The method is based on the geometric matching of the initial subtracks and on the estimation of the lateral movement distributions for both input and final output subtracks. No restrictions on the number of sub-tracks or on the shape of the distributions are needed, neither for the input nor for the output. A number of examples of the redistribution and its effect on aircraft noise calculations are discussed.

The biomechanics of arytenoid adduction surgery are not well understood. An excised canine larynx model was used to study the effects of variable suture tension on glottal configuration and on vocal fold tension (at the midfold and the vocal process). Arytenoid adduction both medializes the vocal fold and closes a posterior glottal chink. Vocal fold tension at the midfold did not vary significantly with suture tension. As suture tension increased to approximately 100 g, vocal fold tension at the vocal process also increased. Beyond 100 g of suture tension, vocal fold tension at the vocal process did not increase. We conclude that the effects of suture tension on the resistance to lateral movement are different at the midfold compared to the vocal process. Procedures for surgical rehabilitation of vocal fold paralysis should address the biomechanical subunits of the larynx individually in order to achieve optimum results.

This research aimed to evaluate mandibular movements in children with and without signs and symptoms of temporomandibular dysfunction. The sample taken consisted of 99 children aged 3 to 5 years distributed in two groups: I - Absence of signs and/or symptoms of TMD (25 girls/40 boys); II - Presence of signs and symptoms of TMD (16 girls/18 boys). The symptoms were evaluated through an anamnesis questionnaire answered by the child's parents/caretakers. The clinical signs were evaluated through intra- and extraoral examination. Maximum mouth opening and left/right lateral movements were measured using a digital caliper. The maximum protrusive movement was measured using a millimeter ruler. The means and standard deviations for maximum mouth opening in Group I and Group II were 40.82mm±4.18 and 40.46mm±6.66, respectively. The values found for the left lateral movement were 6.96mm±1.66 for Group I and 6.74mm±1.55 for Group II, while for the right lateral movement they were 6.46mm±1.53 and 6.74mm±1.77. The maximum protrusion movements were 5.67mm±1.76 and 6.12mm±1.92, in Groups I and II, respectively. The mandibular movement ranges neither differed statistically between groups nor between genders. FAPESP Process 96/0714-6.

Abstract Conventional bone surgery leads to unwanted damage to the surrounding tissues and a slow healing process for the patients. Additionally, physicians are not able to perform free cutting shapes due to the limitations of available systems. These issues can be overcome by robot-assisted contactless laser surgery since it provides less mechanical stress, allows precise functional cuts, and leads to faster healing. The remaining drawback of laser surgery is the low ablation rate that is not yet competitive with conventional mechanical piezo-osteotomes. Therefore, we aim at maximizing the efficiency in hard tissue laser ablation by optimizing the lateral movement speed for different irrigation conditions. The results of this study show a non-linear relationship between cutting rates, speeds, and depths that should be critically considered for integration in robotic laser surgery.

Safe driving can be achieved by prevention of risky situations which requires the knowledge of the vehicle dynamics and road geometry. The Indian traffic condition is heterogeneous in nature and has weak lane discipline. Hence, vehicles interactions takes place laterally also along with their longitudinal interaction. Vehicles lateral movements (interactions) are quite high due to absence of lane discipline. Therefore, the lateral acceleration of vehicles are an important variable which characterizes the corresponding vehicle dynamics. Several studies have been done by various authors on lateral acceleration in curves, however, lateral movement study of vehicles on straight road section is also important to analyze vehicles’ maneuver in such traffic (i.e. traffic stream with weak lane discipline). Therefore, the present study is about the observation of lateral movements of vehicles over different types of roads in three metropolitan cities of India (Kolkata, Mumbai and Pune) under moderate traffic conditions. Lateral acceleration variation of five different types of vehicles (SUV cars, Sedan cars, Hutch Back cars, motorized three wheeler and two wheeler) have been recorded to investigate its relationship with vehicles longitudinal characteristics (i.e. longitudinal speed) in Indian heterogeneous and weak lane disciplined traffic. Lateral acceleration values quickly rises with initial increase in speed afterward lateral acceleration values reduces with further increase in vehicles longitudinal speed.  Impact of vehicle type and locations on the lateral maneuvering of vehicles have also been studied

This paper presents novel algorithms and architecture for a Robot based agricultural implement. The application is for tilling the agricultural field. The hardware consists of a platform with four wheels and a mechanism to facilitate the forward, reverse and lateral movement of the wheels. The platform also houses a turn table, a lift and a plough. Various user defined inputs may be programmed such as length and breadth of the field, spacing between two till lines and depth of tilling. Thereafter, the entire tilling operation of the field is automated. The Robot based vehicle begins the operation from the top left corner and moves towards right tilling the field as it moves forward. Once the required length of field is reached, the vehicle halts and moves to the next row for a specified spacing between tilled rows. The movement from one row to another is in a lateral fashion by rotating the Robotic vehicle wheels by 90 degrees. No tilling is carried out till the next row is reached. The tilling operation is resumed by rotating the plough by 180 degrees and moving the vehicle in the reverse direction. This process continues till the end of the field, covering the entire breadth and maintaining the desired spacing and depth. This automated tilling requires the development of novel algorithms and an optimized architecture, which is presented in this paper. The system is user friendly and upgradable. The entire system has been realized using Verilog and is RTL compliant. The design is both platform and technology independent. The design has been simulated using ModelSim.

Foundation is one of the most important thing in a construction. The frequently used foundation in construction is pile foundation. In Indonesia  the used of pile is adapt by the condition and quality of the soil. Indonesia had many types of soil, and one of them is expansive soil. Expansive soil is a type of clay that had a swelling and shrinkage potential where the swelling happen when the water content is increase and shrink when the water content decreased. One of the mineral that can cause swelling is montmorillonite mineral in expansive soil. The chemical chain between particles that influenced by the increase of water content is causing montmorillonite mineral to swell. The focus of this research is lateral movement that happened to pile as an effect of the swelling properties in expansive soil. This analysis will also inform the effectiveness on using different size and number of pile in expansive soil. Fondasi merupakan salah satu bagian terpenting dalam suatu konstruksi. Salah satunya yang sering digunakan pada proses pelaksanaan konstruksi adalah fondasi tiang pancang. Di Indonesia sendiri penggunaan fondasi tiang pancang disesuaikan dengan kondisi dan kualitas dari tanah yang ada. Indonesia memiliki berbagai macam tipe dan jenis tanah yang berbeda, salah satunya adalah tanah ekspansif. Tanah ekspansif merupakan jenis lempung yang memiliki daya pengembangan dan penyusutan dimana pengembangan tersebut terjadi jika adanya penambahan kadar air dan menyusut ketika terjadi pengurangan kadar air. Salah satu yang dapat menjadi penyebab terjadinya pengembangan adalah kandungan mineral montmorillonite yang terdapat pada tanah ekspansif. Ikatan kimia antar partikel yang dipengaruhi oleh adanya peningkatan kadar air tanah menyebabkan mineral montmorillonite pada tanah ekspansif tersebut akan mengembang. Analisis yang dilakukan akan berfokus pada pergeseran lateral yang terjadi pada  tiang pancang sebagai akibat dari dampak pengembangan yang terjadi pada tanah ekspansif. Analisis ini juga menghasilkan efektivitas pada penggunaan ukuran dan jumlah tiang pancang ditanah ekspansif.
