Estudo de um método automatizado para o cálculo da profundidade de visualização dos equipamentos de ultrassonografia

Ultrasound is the term that describes the sound waves with higher frequencies than human hearing. Ultrasound used in medical diagnosis is a modality based on the use of sound energy and the acoustic properties of the various parts of the body to produce images of stationary and moving tissues. However, despite the ease of use and security that this modality offers for not using ionizing radiation, one should ensure the accuracy and optimum performance of the equipment, which results in precise diagnoses. To accomplish that, periodic quality control tests must be performed, which include: physical and mechanical inspection of the equipment, image uniformity, depth of penetration/visualization, accuracy of distances, axial and lateral resolution, dead zone and doppler sensitivity. This work intends to study a computerized method for calculating the depth of penetration of ultrasound, comparing it to the observerdependent method currently used. The images were collected during the quality control tests of ultrasound equipment. The results of the comparison between the visual and computerized methods were not conclusive for selecting the safest methodology for obtaining the depth of visualization

Estudo clínico comparativo da manutenção do aprofundamento de sulco nas vestibuloplastias mandibulares, através das técnicas de tuneilização submucosa e epitelização secundária

For some time, oral surgeons have tried several surgical procedures to improve the alveolar ridge for prosthetic appliance construction. The techniques used for this purpose are divided into four groups: submucosal vestibuloplasty; secondary epithelization; soft tissue grafting and transpositional flaps. Twenty patients who had problems to wear dentures due to unsatisfactory retention and stability were selected at the Oral and MaxilloFacial Surgery and Traumatology Clinic of Dental School of São José dos Campos. They were divided in two groups and operated by submucosal vestibuloplasty using stents and secondary epithelization vestibuloplasty by Clark's technique and were evaluated twelve months after operations in relationship of the sulcus depth. The results were obtained by clinical and radiological examination before and after surgery, and they are similar to those found in the literature reaching satisfactory functional judgement

Mensuração da profundidade da porção lateral da fossa mandibular, em imagens radiográficas da ATM, obtidas pela técnica transcraniana, em pacientes com dentição decídua, mista e permanente

The author has verified the average depth of the mandibular fossa, in the X-ray image, using the oblique lateral transcranial technique from the right and left sides samples of each patient, which included a total of 176 patients, 87 male and 89 female. The patients were in following phases: deciduous dentítion (the patients had only deciduous teeth in the oral cavity or, if they had any permanent teeth, they could not be in occlusion), mixed dentition (the patients presented deciduous and permanent in the oral cavity) and permanent dentition (the patients had only permanent teeth in the oral cavity), until the eruption of the permanent third molars, in the region from São José dos Campos. São Paulo. Brazil. The patients were under treatment at the Dental School. UNESP (São Paulo State University). ln order to measure the depth of the mandibular fossa in millimeters an imaginary line was traced on the X-ray image, perpendicular to the other line that served as a reference, which was traced from the botton part of the articular eminence up to the tympanosquamous fissure. After the data were obtained and put in a data sheet, they underwent statistical analysis. The results showed that, in the average, the depth of the mandibular fossa in masculine sex is non-statistically signíficant larger than what was observed in feminíne sex, and the right side is larger than the left side, with significant statistical differences. However, only in permanent dentition, in masculine sex, the depth of the mandibular fossa on the right side is larger than on the left side with significant statistical differences

Avaliação de desenpenho do método 3DLBP utilizando mapas de profundidade gerados pelo Microsoft Kinect

Problemas com pose e iluminação são desafios complexos para o reconhecimento de faces 2D. Devido a estes problemas vários métodos para reconhecimento de faces 3D têm sido propostos, principalmente pelo fato que os dados em 3D são mais resistentes a iluminação e são úteis para correção de pose. O maior problema com a utilização de métodos 3D é o custo elevado dos scanners 3D tradicionais. Uma alternativa é a utilização do Microsoft Kinect que, além de ser consideravelmente mais barato, é capaz de capturar os dados de profundidade com precisão necessária para discriminar sujeitos. O principal objetivo do presente trabalho é avaliar a performance do método 3DLBP para o reconhecimento de faces quando utilizando os mapas de profundidade gerados pelo Kinect. Outro objetivo é investigar quais regiões da face que desempenham melhor no reconhecimento de face.

Desempenho de discos de corte de semeadora-adubadora em diferentes quantidades de cobertura vegetal

The quality and efficiency in straw cutting are determinants in the sowing process, according to the occurrence of "tamp" and stops, the magnitude of the straw removal or even the known effects of the seed "envelopment" where the cutting mechanism can not cut the remaining straw. Thus, the objective of this study was to evaluate the performance of different mechanisms for straw cutting of a seeder individualized in different amounts of crop coverage artificially added in a clay soil. The experiment was conducted at Unesp – Sao Paulo State University in the Experimental Farm Lageado, belonging to the College of Agricultural Sciences - Unesp, Botucatu. The experimental design was split plot with four replications, with main plots consisting of five quantities of black oat straw, in area with no-tillage system and subplots of three opening furrows mechanisms, which are: plane disk (PD), corrugated disk (CD) and wavy disk (WD). The wavy disk provided greater rolling resistance, reducing the speed of the set (tractor and equipment). The plane cutting disk showed the highest values of mobilized soil area, deeper penetration into the soil, requiring lower values of vertical force and higher values of lateral force. Regarding the type of waste and doses used, they offered no resistance to cutting and there was no change in the horizontal force on straw.
