Trajectory Analysis of 6-DOF Industrial Robot Manipulators by Using Artificial Neural Networks.

Robot manipulators are robotic systems that are frequently used in automation systems and able to provide increased speed, precision, and efficiency in the industrial applications. Due to their nonlinear and complex nature, it is crucial to optimize the robot manipulator systems in terms of trajectory control. In this study, positioning analyses based on artificial neural networks (ANNs) were performed for robot manipulator systems used in the textile industry, and the optimal ANN model for the high-accuracy positioning was improved.

Analysis of the Vibration Characteristics of a Leaf Spring System Using Artificial Neural Networks.

The real-time vibrations occurring in a leaf spring system may cause undesirable effects, such as stresses, strains, deflections, and surface deformations over the system. In order to detect the most appropriate working conditions in which the leaf spring system will work more stably and also to design optimized leaf spring systems, these external effects have to be detected with high accuracy. In this work, artificial neural network-based estimators have been proposed to analyze the vibration effects on leaf spring systems.

Analysing the effect of robotic gait on lower extremity muscles and classification by using deep learning.

Robotic gait training helps the nervous system recover and strengthen weak muscle groups. Many studies in the literature show that applying robotic gait rehabilitation to patients with neurological disorders such as Multiple Sclerosis (MS), Stroke and Spinal Cord Injection (SCI) effectively restores gait ability. In contrast to the studies in the literature that included only healthy individuals, both the control and patient groups were formed and detailed analyses were carried out for both groups.

A detailed and comparative work for retinal vessel segmentation based on the most effective heuristic approaches.

Computer based imaging and analysis techniques are frequently used for the diagnosis and treatment of retinal diseases. Although retinal images are of high resolution, the contrast of the retinal blood vessels is usually very close to the background of the retinal image. The detection of the retinal blood vessels with low contrast or with contrast close to the background of the retinal image is too difficult.

Design: Retrospective study.

Setting: University hospital.

Intravesical migration of an intrauterine device detected in a pregnant woman.

The intrauterine device (IUD) is common method of contraception among women because of its low cost and high efficacy. Perforations are possible; most perforations occur at the time of insertion, yet the complication can occur with a previously inserted IUD. Perforation of the bladder by an IUD is extremely rare.

Pure gonadal dysgenesis and spontaneous pregnancy: a case report.

We report a case of pure gonadal dysgenesis with streak gonads in which spontaneous conception occurred 10 years after the diagnosis. Her pregnancy proceeded as normal, and she gave birth to a live baby at term by cesarean section. A lactation period lasting for 1 year and afterwards proceeded as amenorrheic.

Markedly elevated serum alkaline phosphatase level in an uncomplicated pregnancy.

In normal pregnancy, although maternal serum alkaline phosphatase increases and reaches the two-fold of non-pregnant serum level, above this level, hepatic, renal, osteal diseases and malignancies should be kept in mind. We report a case of 28-year-old pregnant woman with increased maternal serum level of alkaline phosphatase activity (17-fold) due to an increased level of placental isozyme. She delivered vaginally a healthy female baby.

Pretreatments before the induction of ovulation in assisted reproduction technologies: evidence-based medicine in 2007.

Many pretreatment modalities used prior to ovulation induction have been proposed to increase the success rate in women undergoing assisted reproductive technologies. However, no clear evidence from well-designed clinical trials has shown a benefit of these treatments. We conducted a systematic review to explore the effect of different pretreatment therapies on outcomes of in vitro fertilization (IVF) cycles.
