People usually research modulation mode 3 of SVM for matrix converter discussed in this paper. Actually, other different modulation modes of SVM for matrix converter are worth studying. Two novel modulation modes are put forward for matrix converter for the first time in this paper, expanding its modulation modes of SVM. First, SVM for matrix converter is described. Then the 3 modulation modes ...

The matrix converter system is competitive solution to replace the conventional two stage ac to ac converter. In this paper, a matrix converter driving a speed-controlled induction machine is examined under open-switch fault. First, a-predictive direct torque method is proposed using only the motor torque and current. Second, a motor speed control is presented. The proposed techniques do not re...

INTRODUCTION Identifying newborns who weight 4000 g or more is important because birth of macrosomic fetuses is associated with adverse peripartum outcomes. Ultrasound is widely used for this purpose Our objective was to evaluate the diagnostic value of sonographic measurement of fetal abdominal circumference (AC) over 350 mm for the prediction of fetal macrosomia and shoulder dystocia, to spec...

INTRODUCTION Surgical treatment of chronic complete acromioclavicular (AC) joint dislocation is still debated and no gold standard surgical procedure has been identified. MATERIALS AND METHODS A retrospective series of 90 patients treated for AC dislocations is reported here. Patients were divided into three groups: group 1 receiving AC reconstruction with a Dacron vascular prosthesis; group ...

background patients who have shoulder pain usually have compensatory or contributory deviation of shoulder motion during arm elevation. in the traditional scapulohumeral rhythm, the share of the acromioclavicular (ac) and the sternoclavicular (sc) joint movements and also the role of ac internal rotation angle are unknown. objectives the main purpose of this study was to measure and compare the...

PURPOSE To compare the long-term efficacy of a secondarily implanted flexible angle supported anterior chamber (AC) intraocular lens (IOL) with sclerally fixated IOL as a secondary procedure in patients with aphakia. METHODS Sixty patients with aphakia were recruited for this study. The patients were randomly divided into two groups: Group I patients underwent secondary implantation with AC I...

OBJECTIVE To determine whether changes in serum cortisol (CORT) and PRL are affected by acupuncture (Ac) in Ac-treated IVF patients. DESIGN Prospective cohort clinical study. SETTING Private practice reproductive endocrinology and infertility clinic and private practice acupuncture consortium. PATIENT(S) Sixty-seven reproductive-age infertile women undergoing IVF. INTERVENTION(S) Blood ...

OBJECTIVES To assess the ability of a 12-week primary care-based intensive lifestyle intervention (ILI), to facilitate a 5% reduction in baseline weight compared with an education-only active comparator (AC).  Methods: A randomized clinical trial was conducted in a primary health care setting in Jeddah, Saudi Arabia between December 2014 and June 2015. Arab participants with obesity, but who we...

AIMS To assess the integrity of the ocular surface epithelium in patients with atopic dermatitis from the viewpoint of its barrier function. METHODS 49 patients with atopic dermatitis with blepharoconjunctivitis (ABC group), 27 age matched patients with seasonal or perennial allergic conjunctivitis (AC group), and 20 volunteers with normal healthy eyes (NH group) were assigned to this study. ...

OBJECTIVE To compare the anaesthetic properties of conventional intradermal 1% plain lignocaine with a topical gel preparation of adrenaline (1:2000) and cocaine (4.7%) for use in treatment of children's lacerations. METHODS Children aged 3-16 years with lacerations (not of the digits or mucous membranes) were consecutively assigned to receive either adrenaline and cocaine (AC) or lignocaine....
