This paper presents experiments with a new algorithm for the unseady (tranient) thrust control bladed-propeller marine thrusters. Comparative experiments over a wide range of unsteady operating conditions with three different thrust control algorithms demonstrate the model-based control algorithm to offer transient thrust-control performance superior to that of its non-model-based counterpart. ...

Understanding the folding style of a fold-thrust belt is crucial to understand the nature and structural history of structures that may trap natural resources within the belt. In this research, the geometry and mechanism of a number of fault-related folds has been investigated based on field data and satellite image interpretations. The main study areas are: the Sohrevard and Ushtaniyan anticli...

Linear flux-switching permanent magnetic (LFSPM) machines are good choices for long stroke applications. These machines deliver high thrust force density in addition to the machine structure where permanent magnetics (PMs) and windings are all on the short mover. For LFSPM machines, their performance is always affected by big thrust force ripple. In this paper, for two C-core LFSPM machines of ...

background and objectives: squamous cell carcinoma of the tongue (sccot) is the most common malignant neoplasm in oral cavity. at the time of the diagnosis of sccot regional metastases with a high mortality rate are common, which is due to the extensive lymphatic system drainage of the tongue. although the level of healthcare has significantly improved, the survival rate is still low with an un...

granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. occurrence in limbs is even rarer. these tumors account for approximately 0.5% of all soft tissue tumors. granular cell tumor can also affect other organs including skin, breast, and lungs. local recurrence and metastasis is potentially higher in m...

Maintenance of a patent airway is the most important aspect of the safe administration of anesthesia in children. However, in spontaneously breathing, anesthetized children, upper airway obstruction is a frequent problem (1) and failure to maintain a patent airway can rapidly result in hypoxemia, bradycardia or even cardiac arrest. Upper airway narrowing is most likely to appear in pharyngeal s...

CO2 refrigerant with a high operating pressure has a large difference between the suction and discharge pressures in compressors. Because of a load increase, the high performance and high reliability of compressors are required. Compared to the scroll compressor employing the conventional refrigerant, the thrust load increases in the CO2 scroll compressor. Therefore the design of thrust bearing...

The influence of deformation on aerodynamic characteristics is studied in this paper. To study the influences of deformation magnitude and range separately, a kind of twopart flapping wing model is designed, which separates the deformation magnitude and range, and makes the measurement of deformation easier. A series of wind-tunnel experiments are carried out to explore the influence. The exper...

Background and Aim: Benign migratory glossitis, or geographic tongue, is usually an asymptomatic inflammatory disorder of unknown etiology that affects the epithelium of the tongue. Among the etiologic factors proposed, emotional causes were suspected by several investigators. The objective of this study was to evaluate the anxiety and cortisol level in patients with geographic tongue compared ...
