Abstract:
The tongue is a muscular hydrostat which is a part of oral cavity. The interaction of tongue with palate is essential for articulation of speech and swallowing of food. Patients with neurological disorders have impaired speech and swallowing problem. In this work, a device is envisioned to provide a non-invasive rehabilitation aid for speech and swallowing disorders. The proposed device serves as both diagnostic and therapeutic tool. The parameters of the proposed device are tongue pressure measurement and tongue color detection along with neuromodulation stimulator (tongue stimulator – therapeutic aid). The output, which is a waveform (tongue pressure) and an image (tongue color) are transmitted wirelessly outside the oral cavity to the computer. This device is used to investigate and quantify the degree of tongue disorder. Periodic rehabilitation therapies along with the proposed device, increases the chances of recovery of functional tongue disorders by 50% within a short interval of time.

ABSTRACT This case report describes the interdisciplinary management of a 58-year-old woman who was missing lower first molars and supraerupted maxillary first molars. The treatment plan included intrusion of the upper first molars and corticotomy-assisted mandibular second molar protraction with the aid of temporary anchorage devices. Miniscrews were effective in intrusion of the maxillary first molars and protraction of the lower second molars. Although good functional outcome was achieved in 41 months, the corticotomy-assisted procedure did not significantly reduce the treatment time.

Abstract:
AbstractTwo large-breed dogs underwent delayed surgical repair of pelvic fractures with the aid of a skeletal traction device. Distraction and reduction in the fractures using the skeletal traction device were monitored by direct visualization and intraoperative fluoroscopy. Postoperative radiographs revealed good to near-anatomical bone reduction and fracture alignment without narrowing of the pelvic canal. Both dogs had complete functional recovery with no evidence of neurological deficits. The use of a skeletal traction device should be considered for reduction and fixation of delayed pelvic fractures.

Abstract:
Microencapsulation is a widely studied cell therapy and tissue bioengineering technique, since it is capable of creating an immune-privileged site, protecting encapsulated cells from the host immune system. Several polymers have been tested, but sodium alginate is in widespread use for cell encapsulation applications, due to its low toxicity and easy manipulation. Different cell encapsulation methods have been described in the literature using pressure differences or electrostatic changes with high cost commercial devices (about 30,000 US dollars). Herein, a low-cost device (about 100 US dollars) that can be created by commercial syringes or 3D printer devices has been developed. The capsules, whose diameter is around 500 µm and can decrease or increase according to the pressure applied to the system, is able to maintain cells viable and functional. The hydrogel porosity of the capsule indicates that the immune system is not capable of destroying host cells, demonstrating that new studies can be developed for cell therapy at low cost with microencapsulation production. This device may aid pre-clinical and clinical projects in low- and middle-income countries and is lined up with open source equipment devices.

Abstract:
Introduction: Lateral compression type 1 (LC1) pelvic ring fractures make up 63% of all pelvic ring injuries. This fracture pattern is typically seen in older patients. The purpose of this study is to assess the ambulatory status of individuals sustaining LC1 fractures at long-term follow-up and what specific characteristics, if any, effect this status or functional outcomes. Methods: Over a 2-year period, all pelvic ring injury at 2 hospitals within one academic institution was queried. One hundred sixty-one low-energy LC1 pelvic fractures were identified. Results: Fifty patients were available for long-term outcomes (mean: 36 months). Long-term functional outcomes (mean follow-up: 36 months) as measured by SMFA subgroup scores were demonstrated to be 3 times higher in patients currently using assistive devices for walking ( P = .012). Increased age ( P = .050) was associated with the continued use of assistive walking devices. Of the patients who did not use an ambulatory device prior to LC1 injury, 5 (11.6%) sustained a fall or medical complication within 30 days of the index pelvic fracture; this was associated with the current use of an assistive ambulatory device ( P = .010). Forty-three (86%) patients didn’t use an assistive ambulatory device prior to sustaining the LC1 fracture. Seven (14%) patients utilized assistive devices both before and after the LC1 injury. Thirteen (26%) patients, who did not utilize assistive ambulatory devices prior to their injury, necessitated them at long-term follow-up. Discussion: Surgeons should be aware of these associations, as they can implement early interventions aimed at patients at risk, for assistive device use, following LC1 pelvic fractures. Conclusion: More than a quarter of the patients sustaining an LC1 pelvic fracture continue to use an aid for ambulation at long-term follow-up. Older age, complications, and falls within 30 days of this injury are associated with the utilization of an assistive ambulatory device.

Abstract:
People’s daily life activities, such as eating, washing and dressing, are very important to the quality of life. However, for many people with disabilities, including those with upper limbs, these tasks prove to be challenging without the help of human caregivers. However, the shortage of medical workers and rising medical costs have created an urgent need for innovation, making aid more affordable and effective. A typical auxiliary task is dietary assistance, which is the basic daily necessities for maintaining health. People with upper limbs and limbs often have difficulty supporting themselves. Technical intervention can solve the problem by bridging the gap between physical ability and necessary functional ability. This design is based on a single-chip microcomputer control system-assisted feeding manipulator design, which can assist in completing the feeding function, and can also add voice or facial recognition modules to enhance the human-computer interaction experience. The design is mainly composed of editing controller-control and detection-power element. That is, the food is fed through a control program, transmitted to a target position through a power element, and whether feeding is completed is judged through a control and detection device. And we will try to add some functional modules to enhance the human-computer interaction experience.

Abstract:
A new, nonelectronic hearing aid was studied in 112 patients with mild sloping sensorineural hearing loss. The device, worn all in the ear and made of clear plastic, produced a mean functional gain of 9.6 dB at 1500 Hz, 12.4 dB at 1750 Hz, and 9.1 dB at 2000 Hz, with lesser gains at adjacent frequencies between 1000 and 2500 Hz. Speech discrimination in quiet and in noise was improved. Patient acceptance of the device (in a group of 884 patients) was 76%. The device appears to be useful in the treatment of mild hearing loss.

Abstract:
Abstract The research objective is design of the information technology for automated control system model synthesis for reducing the labour intensity of the digital machine model design by improving the control system information conversion tools. The structural-functional digital machine models are proposed for project development of robotic manipulator control devices. Application of the structural-functional digital machine models allows reducing labour intensity and project timing of robotic center control system design due to the cycle scheme conversion to intermediate representation, which is convenient for digital machine synthesis using the modern development tools. When applying the proposed structural-functional model a process engineer can rely on keeping all important technological process details and a programmer can avoid a large amount of errors when developing the device algorithms. The developed algorithm can be represented as state diagrams, which can be adapted for integrated scheme crystal as a digital machine using the specific tools of computer-aid design.

Abstract:
Abstract Bi-functional metamaterial resonance device operated at terahertz frequency is designed in this paper. It is composed of three metallic strips, in which two parallel metallic strips having the identical dimensions are arranged in the longitudinal direction, and a single metallic strip deviated from the center position is arranged in the horizontal direction. Bi-functional resonance effects of plasmon-induced transparency (PIT) and Fano-like response are simultaneously obtained in this simple metamaterial structure. The formation mechanisms of the two resonance effects are analyzed with the aid of the near-field distributions and the dependence of structure parameters on the whole resonance performance. Results further show that the metallic strip placed horizontally plays an important role in adjusting the resonance response of the metamaterial resonator. More importantly, when the deviation value of the metallic strip in the horizontal direction exceeds a certain amount, for example 10 μm, the metamaterial resonator can realize the effective regulation from bi-functional resonance to single-functional PIT effect. Our proposed structure can be used as valuable platform for ideas to inspire the design of novel electro-optic devices.

Abstract:
Context: Although the mass-transport system Transmilenio provides audio information for travelers’ guidance, this is not helpful enough to blind users who are not able to transit easily within the system. For these reason, portable guidance devices are needed to improve the level of autonomy of the visually impaired people while using the transport system.Method: A review of aid devices to improve the level of autonomy of people with visual impairment was conducted so as to define the most practical technology for building an affordable device usable in the city of Bogotá. Subsequently, the functional modules of the device were defined, including file storage, sound reproduction, user interface and satellite geolocalization and location. Once built, the operation of the device was tested with 10 volunteers in condition of visual impairment who were oriented with the device between two main stations of one Transmilenio line; a final statistical study was conducted on the operation and usability perception of the device by the users.Results: 100% of the users were able to reach their destination successfully in the pilot test. In regards to the usability perception, users highlighted features such as sound indications for setting the device and orientation guidance throughout the journey. On the other hand, one of the main difficulties found was to correctly identify the bus approaching the stop and similarly locating the corresponding boarding door, as multiple bus routes may alight in the same door.Conclusions: The device was built incorporating low-cost technologies intended to make it affordable in an eventual mass—scale production. Likewise, a discreet design was chosen so as to lessen the risk of robbery, which unfortunately is a frequent issue in the Transmilenio system due to overcrowding of buses and stations. Additionally, we remark that the prototype can be made smaller by using special—purpose circuit boards. Policy-makers may take into account these considerations for an eventual wide implementation as part of governments’ plans for mobility inclusion in mass-transport systems for disabled people, in comparison with other alternatives such as smart cell phonesLanguage: Spanish.

Abstract:
With improvements in actuation technology and sensory systems, it is becoming increasingly feasible to create powered exoskeletal garments that can assist with the movement of human limbs. This class of robotics referred to as human-machine interfaces will one day be used for the rehabilitation of paralysed, damaged or weak upper and lower extremities. The focus of this project was the development of an exoskeletal interface for the rehabilitation of the hands. A novel sensor was designed for use in such a device. The sensor uses simple optical mechanisms centred on a spring to measure force and position simultaneously. In addition, the sensor introduces an elastic element between the actuator and its corresponding hand joint. This will allow series elastic actuation (SEA) to improve control and safely of the system. The Hand Rehabilitation Device requires multiple actuators. To stay within volume and weight constraints, it is therefore imperative to reduce the size, mass and efficiency of each actuator without losing power. A method was devised that allows small efficient actuating subunits to work together and produce a combined collective output. This work summation method was successfully implemented with Shape Memory Alloy (SMA) based actuators. The actuation, sensory, control system and human-machine interface concepts proposed were evaluated together using a single-joint electromechanical harness. This experimental setup was used with volunteer subjects to assess the potentials of a full-hand device to be used for therapy, assessment and function of the hand. The Rehabilitation Glove aims to bring significant new benefits for improving hand function, an important aspect of human independence. Furthermore, the developments in this project may one day be used for other parts of the body helping bring human-machine interface technology into the fields of rehabilitation and therapy.

Este trabalho apresenta uma proposta de metodologia do objeto matemático Função Exponencial, que possibilite o desenvolvimento de habilidades interpretativas e criativas de potencial significado para os alunos, a partir de uma sequência didática estruturada à luz da Teoria das Situações Didáticas de Guy Brousseau e, dos Registros de Representações Semiótica de Duval, proporcionando interações entre o aluno, o professor e o meio em um ambiente de aprendizagem cooperativo, onde os alunos se sintam livres para expressar as suas ideias e para sugerir as suas próprias abordagens. A metodologia proposta foi desenvolvida de acordo com o conhecimento a priori do aluno, valorizando as suas diferentes formas de registros, os quais são de extrema importância durante os processos de ensino e de aprendizagem. A proposta foi aplicada a alunos do primeiro ano do ensino médio do Colégio Estadual José de Anchieta Ensino Fundamental e Médio, localizado na Cidade de Dois Vizinhos – Paraná. Para o desenvolvimento da pesquisa utilizou-se a ferramenta metodológica Engenharia Didática de Artigue, uma metodologia originada especificamente para a pesquisa com situações didáticas. A princípio o objetivo proposto foi atingido, o qual consistia de trabalhar a parte conceitual, do significado da Função Exponencial, da relação de dependência e sua principal característica, ou seja, que a parte variável se encontra no expoente. E, sem imposição, mas a partir de situações didáticas apropriadas, segundo a teoria das situações didáticas, os alunos foram capazes de perceber essa característica, de resolverem problemas que envolviam a função exponencial e, além disso, de inventarem problemas (de acordo com o seu universo) modelados por este tipo de função. Acredita-se que a metodologia à luz da teoria das situações didáticas, análises dos registros dos alunos, observações sobre os erros e obstáculos e reflexões sobre aspectos do contrato didático são de fundamental importância para a prática docente e, determinantes durante o processo de ensino aprendizagem.
This essay presents a proposal on methodology over the mathematical object Exponential Function which enables the development of interpretative and creative skills with potential meaning to the students starting from a didactic sequence structured on the light of The Theory of Didactic Situations from Guy Brousseau and, from the Records of Semiotic Representation of Duval, providing interactions among the students, the teacher and the environment of cooperative learning where the students feel free to express their own ideas as well as to suggest their own approaches. The methodology presented has been developed according to the students first knowledge, valuing their different ways of registering, which have such an important role during the teaching and learning processes. The proposal has been applied to the students from the first year of high school of Colégio Estadual José de Anchieta Ensino Fundamental e Médio, located in a town called Dois Vizinhos –Paraná. In order to the development of the research the methodological tool Didactic Engineering Artigue which consists in a methodology developed only to the research with didactic situations. The main goal has been reached at first, which was to work on the conceptual part of the Exponential Function, the relation of dependence and its main characteristic so that the variable part is in the exponent. Moreover with no imposition but starting from suitable didactic situations, the students were able to realize that they could solve the problems which involve the exponential function and furthermore create new problems (according to their universe) modeled by this kind of function. Its believed that the methodology based on the theory of didactic situations, analysis of students registers, observation on mistakes and obstacles as well as reflections over the aspects of the didactic contract are of fundamental importance to the teaching practice and determinant during the teaching-learning process.

The population of aged persons is increasing. Due to the joints, muscles and physical fitness of human’s body will gradually degenerate as the age increases, the demand for walking-aid device, therefore, is gradually increasing. Even though the two-function wheeled walker with sitting device has been on the market, its main function is still for walking and not used as wheelchair. The attached sitting device is only for sitting to take a rest. On the other hand, most the wheelchairs are heavy and take up large space while folded, and therefore are not convenient to carry. In case of going outside and needs to bring both walker and wheelchair, it is obvious that requires spend more money to purchase, take up more space and inconvenient to carry. This study presents a novel mechanism design for a foldable walking-aid device with functions of walker and wheelchair. It uses a four-bar linkage to execute the transformation between walker and wheelchair, which results in a lower back height of walker than that of wheelchair. The foldable mechanism applies a Watt-II type six-bar linkage to design, which will take up less space and become a straight column standing on the floor after folded for conveniently carrying outside. This novel design has constructed via Solidworks software and performed the interference check and kinematic simulations via the functions provided by Solidworks to confirm its correctness of design. This study has completed a scaled model of this novel mechanism to perform its operation. The preliminary result has confirmed its feasibility.

The thesis is divided into three parts. The first part deals with the synthesis of CF3-terminated alkanephosphonic acid molecules with different chain lengths and the self-assembled monolayers(SAMs) formed by these molecules on Al substrate. SAMs of CH3-terminated alkanephosphonic acids with different chain lengths were also formed for comparison. Mixed monolayers formed from these two components were prepared. The surface structures and properties were characterized by using ellipsometry, reflection absorption IR (RAIR), contact angle and photoelectron spectrometer (AC-2). In the second part, similar monolayers as well as mixed monolayers were formed on ITO substrate. The surface properties were investigated by contact angle, photoelectron spectrometer, and X-ray photoelectron spectroscopy. A linear correlation between the ITO work function and the composition of the adsorbing solutions was observed. In the third part, organic light-emitting devices were fabricated with SAM-modified ITO as the anode substrate. The I-V curves, current density, and the luminous efficiency were analyzed to elucidate the charge balance situation in the devices. The performance of the devices with a configuration of ITO-SAM/HTL/Alq3/LiF/Al showed that, with molecules of same terminal functional group as modifier, the current density decreased with increasing chain length, whereas the luminous efficiency increased with increasing chain length. On the other hand, with mixed monolayer as modifier, the current density depends on the work function and thus the injection barriers. The luminous efficiency exhibits a maximum with ITO modified with 1:1 ratio of fluorinated and protiated hexanephosphonic acid as anode, suggesting a more balanced hole/electron carriers under the specific condition.

The focus of the research reported on in this dissertation is an evaluation of the Language in Learning and Teaching project (LILT), in terms of its ability to facilitate English language development in schools where both educators and learners are second language speakers and where the Language of Learning and Teaching (LoLT) is English. The research involved two main phases. During the first phase I established evaluation criteria from the literature review, from another project the English Language Education Trust, (ELET) and from my own experience and feedback from the end-users (Le. teachers) and the observation of workshops. In the second phase I evaluated the LILT materials against the criteria developed in the literature review, analysed the feedback from end-users in the form of a questionnaire and made recommendations. In this dissertation the following terms will be used interchangeably: teacher, educator, facilitator and tutor because in the quoted passages, the term teacher is largely used. However, in Outcomes-Based Education (OBE) the terms educator, facilitator and tutor are used.

Abstract:
Abstract Human hands are made to do everything: grasp objects, communicate, perform daily tasks, and learn. Certain people with difficulties using their hands are affected greatly by spasticity, uncontrolled tightness in hand muscles, and impaired motor function in their hands. Hand spasticity specifically can be caused by several medical conditions including cerebral palsy, stroke, arthritis, and carpal tunnel. Often an individual's hand remains in a clenched fist position causing pain and limited mobility within the fingers. Many products exist on the market that specifically help meet the clinical needs of opening and extending a hand for long periods of time. Individuals can purchase products, but they are usually only used during occupational therapy sessions due to their high cost. The Hand Extender is a wearable designed for participants who struggle with functional use of their hands, and over time the Hand Extender is designed to support and aid their hand in everyday functions. Similar products only come in a few standard sizes, resulting in potentially poorer fit, e.g., commercially available products are not currently sized for the pediatric population or participants with an abnormal hand size. The custom fit glove of the Hand Extender made possible via 3D printed parts accommodates all participant populations with a variety of different hand sizes. The tailored glove also provides more accurate extension due to the better fit. A custom fit 3D Hand Extender was able to accurately fit two adult participants with different sized hands and normal hand function.

Abstract:
Abstract A novel device-level micropackaging that may encapsulate functional devices in post packaging has been developed. The encapsulation is formed with a metallic microcap like a dome shape to shield necessary micro devices from external impact or contamination. The metal cap is initially fabricated on a carrier glass and then transferred onto a host substrate. In this micropackaging, the micro assembly transfer and cap leg-snapped techniques are utilized in successfully demonstrating the transferred cap on the selected area of the host substrate that is aligned through the transparent glass. The low temperature solder bonding also allows this technique to be compatible with existing integrated circuit and micromachined devices. Furthermore, the robustness of the electroplated micro cap is even superior to the reported surface micromachining technique due to the high stiffness of a thicker structure by controllable electroplating. With the effective aid of the numerical analysis of the cap leg, the fracture can be expected at a desirable spot in which the stress concentration occurs under pulling forces for separation of the carrier glass and the cap. As a result, the micro encapsulation presents a successful, new packaging technique with advantages of selective 3D micro packaging, sealing, robustness, back-end process compatibility and potentially low cost.

Abstract:
Abstract The paper describes the design and structural optimisation of a mechanical system from the functional, safety, reliability and cost viewpoints, using a flexible, rapid approach which was developed from the integration of two methodologies: Axiomatic Design and FMEA. In particular, thanks to the information obtained from Axiomatic Design, FMEA is not carried out on the entire system but only on the components and subsystems which are more critical. This makes it possible to establish an order of priority for intervening on components or Design Parameters of a system which can be applied both prior to designing the system or in the diagnostic and validation phase of an already existing product. This approach has been validated by its application to the electro-hydraulic command of the working device of an Orenstein & Koppel (O&K) earth-moving machine.

Abstract:
Essential Tremor (ET) is the most common movement disorder among adults. This paper presents a device to induce the effects of ET in the wrists and hands of otherwise healthy research participants for use in inclusive design studies. The device, called “The HandShake,” reproduces the functional impairment of ET sufferers on design study participants. Existing solutions can require complex or expensive equipment. The HandShake uses a novel low-cost system based around a single RC servo. Users of the device in validation testing were found to be impaired in a manner similar to ET sufferers. This tool is intended to aid future inclusive design research regarding upper extremity disabilities. We present results regarding the validity of the simulated tremors versus data from those suffering with ET.

The partial goals are the creation of a teaching aid, the construction of a unique facility and the creation of opportunities for research and development in this area by other students. Using a measuring device, it was possible to record the various operating characteristics of the internal combustion engine. Based on this, the usability of individual propellers for the measured internal combustion engine can be determined.

American Society of Mechanical Engineers, 2017. http://dx.doi.org/10.1115/dmd2017-3491.

Full text
Abstract:
Developing a successful cardiac device requires detailed knowledge of cardiac mechanical properties. For example, tissue failure characteristics and compliance feed into design criteria for many pacemaker leads (Zhao et al., 2011). In the right atrium, tensile forces are exerted on the right atrial appendage in multiple clinical procedures. In a traditional lead implant, mechanical manipulations with a stylet aid a clinician in assessing lead fixation, with a seldom used “tug” test providing additional input. Atrial lead dislodgement remains one of the top complications for bradycardia pacing leads (Chahuan et al., 1994), in part because there is no standard mechanical assessment at implant to verify fixation. Thus, a deeper understanding of forces exerted on the atrium during implant, is fundamental to understanding the problem. Further characterization of the biomechanics relevant to atrial device implants will provide valuable design input for fixation tests and help drive research toward new atrial fixation mechanisms. This study aims to better define the relationships between right atrial stiffness and the chamber pressures within the right atrium, so to characterize the link between tensile displacement within the right atrium, and the force exerted on an implanted device in a functional heart. These experiments quantitatively define the fixation force of a fixed cardiac device with a given pulled displacement; i.e. displacing the device a given distance will effectively ensure the experimentally derived fixation force.

Abstract:
Abstract. Nucleic acid based electronic devices have attracted particular interest over the past two decades due to its ability of long-range charge transport and self-assembly. The π-π interactions of the stacked bases are believed to be responsible for the long-range charge transport. The insertion of intercalators could alter electronic structure of the host nucleic acids which may influence the charge transport through the nucleic acid. The influence of intercalators on charge transport through the host nucleic acids largely depends on ionization potentials of the intercalators. Therefore, in this work we intend to determine vertical and adiabatic ionization potentials of the nucleic acid intercalators by using density functional theory calculations using Gaussian 16 package. We also explore the role of solvent and discuss the significance of ionization potential values in comparison with the ionization potential values of nucleic acid bases. Ionization Potential values of these intercalators range from 7.67 eV to 11.12 eV and 4.5 eV to 6.46 eV in vacuum and aqueous medium, respectively. Daunomycin is found to have lowest ionization potential value in vacuum as well as in aqueous medium. On the other hand, Proflavine (Anthraquinone) has highest ionization potential value in vacuum (aqueous medium). Non-planar intercalators exhibit distinct vertical and adiabatic ionization potential values and decrease drastically upon solvation.

Abstract. Organo metallic halide perovskite solar cells (PSCs) have attracted much attention due to the enhanced photovoltaic performance and wide absorption in the visible region. In this work, a perovskite solar cell device with mixed halide perovskite CH3NH3PbI3-xClx as the active layer was fabricated in the normal device architecture and investigated. The effect of device performance was compared by introducing copper phthalocyanine (CuPc) as a hole transport layer (HTL). It is seen that device with a transport layer exhibits a better performance and power conversion efficiency (PCE) than the device without an HTL. The carrier mobility was determined using the space charge limited current (SCLC) method and found to be 0.0013cm2/Vs.

Abstract:
Abstract The preliminary design and analysis of a meso-scale refrigerator is presented here. The device is to be designed out of layers of silicon wafers bonded together and is to be fabricated through the techniques of microelectronics. The intended application of the device is an integrated heat removal system for electronics or photonic chips or modules. The paper presents a functional decomposition of the entire system, thermodynamic feasibility analysis, alternative configurations for two of the functions: actuation and compression, and parametric analysis for two alternative candidates for compressor actuation. A set of reasonable design requirements is first formulated. Overall function of the devices is decomposed into nine major sub-functions. Comparison of different alternatives for compression and actuation suggests that electrostatic actuation integrated with centrifugal compression is a viable option. Two different ways to implement electrostatic actuation are considered in details: variable capacitance motor and electrostatic induction motor. A set of design relations and criteria needed to obtain the optimal design of each motor is presented along with a discussion on relative effects of the main design parameters.

Full text
Abstract:
A research investigation was conducted on the erosion potential of stabilized subbases under concrete pavements and asphalt layers supporting concrete overlays. Through field surveys and testing in Illinois, this project evaluated if existing concrete pavements with stabilized subbases and concrete overlays were exhibiting potential erosion of the underlying support layer. The field evaluation testing included falling weight deflectometer testing, distress surveys, coring, and ultrasonic tomography scanning. A laboratory performance test was also established using the Hamburg wheel-tracking device to assess the erodibility of the various stabilized subbase layers for new construction and existing asphalt layers available for a concrete overlay. The analyzed field test results were coupled together with the laboratory performance testing to provide recommendations for updating the Illinois Department of Transportation’s “Bureau of Design and Environment Manual” guidance. No changes were recommended for hot-mix asphalt stabilized subbases, but testing using the Hamburg wheel-tracking device should be considered for Portland cement concrete stabilized support layers (e.g., CAM II) under concrete pavements. For testing of asphalt support layers for concrete pavement overlays, the Hamburg wheel-tracking device is recommended with performance criteria similar to flexible pavements for appropriate functional classes.

Abstract:
Review question / Objective: - Does the osseodensification drilling technique increase primary stability in low-density bone? - The aim of the present investigation was to evaluate primary stability in dental implants in people with low density bone using the osseodensification technique. Condition being studied: The replacement of missing teeth through dental implants is currently the most practiced in dental clinics. The main criterion for determining the success of an implant is osseointegration, which is a direct structural and functional connection between vital bone and the prosthetic load-bearing surface of an implant. In the same way, primary stability must be obtained for a good lasting clinical result of the implant and to achieve this purpose, the bone density must be evaluated where the dental implant is to be placed. Salah Huwais in 2013 introduced a new osteotomy procedure (Oseodensification) for site preparation without removal and bone preservation. The Osseodensification process produces an autograft layer around the implant with the osteotomy surface, the autologous bone comes into contact through an endosteal device that accelerates osseointegration due to the nucleation of osteoblasts in the instrumented bone adjacent to the implant and has a greater primary stability due to contact between the device and the bone.

Full text
Abstract:
Currently, to evaluate the dynamic characteristics of objects, quite a large number of devices are used in the form of chronographs, which consist of various optical, thermal and laser sensors. Among the problems of these devices, the following can be distinguished: the lack of recording of the received data; the inaccessibility of taking into account the trajectory of the object flying in the sensor area, as well as taking into consideration the trajectory of the object during the approach to the device frame. The signal received from the infrared sensors is recorded in a separate document in txt format, in the form of a table. When you turn to the document, data is read from the current position of the input data stream in the specified list by an argument in accordance with the given condition. As a result of reading the data, it forms an array that includes N number of columns. The array is constructed in a such way that the first column includes time values, and columns 2...N- the value of voltage . The algorithm uses cycles that perform the function of deleting array rows where there is a fact of exceeding the threshold value in more than two columns, as well as rows where the threshold level was not exceeded. The modified array is converted into two new arrays, each of which includes data from different sensor frames. An array with the coordinates of the centers of the sensor operation zones was created to apply the Pythagorean theorem in three-dimensional space, which is necessary for calculating the exact distance between the zones. The time is determined by the difference in the response of the first and second sensor frames. Knowing the path and time, we are able to calculate the exact speed of the object. For visualization, the oscillograms of each sensor channel were displayed, and a chronograph model was created. The chronograph model highlights in purple the area where the threshold has been exceeded.

Abstract:
The objectives of this study were to investigate soil-pneumatic tire interaction and develop traction-soil compaction prediction model. We have developed an inverse solution technique that employs a response surface methodology to determine engineering properties of soil in-situ. This technique is useful in obtaining actual properties of soil in-situ for use in traction and soil compaction studies rather than using the values obtained in the laboratory by employing remolded and/or disturbed soil samples. We have conducted extensive field tests i the U.S. to develop semi-empirical traction prediction equation for radial ply tires. A user friendly traction-soil compaction program was developed to predict tractive ability of radial ply tires using several different techniques and to estimate soil compaction induced by these tires. A traction prediction model that incorporates strain rate effects on the tractive ability of tires was developed in Israel. A mobile single wheel tester and an in-situ soil test device were developed i Israel to significantly enhance the ability of Israeli investigators to conduct traction-soil compaction research. This project has resulted in close cooperation between UCD, Technion, and ARO, which will be instrumental in future collaboration.

Abstract:
A model of the energy balance of a transpiring crop in a greenhouse was developed in a format suitable for use in climate control algorithms aimed at dissipating excess heat during the warm periods. The model's parameters use external climatic variables as input. It incorporates radiation and convective transfer functions related to the operation of control devices like shading screens, vents, fans and enhanced evaporative cooling devices. The model identified the leaf boundary-layer resistance and the leaf stomatal and cuticular resistance as critical parameters regulating the temperature of the foliage. Special experiments evaluated these variables and established their relation to environmental factors. The research established that for heat load conditions in Mediterranean and arid climates transpiring crops maintained their foliage temperature within the range allowing high productivity. Results specify that a water supply ensuring minimum leaf resistance to remain below 100 s m-1, and a ventilation rate of 30 air exchanges per hour, are the conditions needed to achieve self cooling. Two vegetable crops, tomato and sweet pepper fulfilled maintained their leaf resistance within the prescribed range at maturity, i.e., during the critical warm season. The research evaluates the effects of additional cooling obtained from wet pad systems and spray wetting of foliage.
