This paper addresses about an approach that suggests for stock portfolio optimization using the combination of Adaptive Neuro-Fuzzy Inference System (ANFIS) and Capital Asset Pricing Model (CAPM). Stock portfolio optimization aims to determine which of the stocks to be added to a portfolio based on the investor’s needs, changing economic and market(More)
INTRODUCTION We studied the feasibility of ex-vivo nephron-sparing surgery and autotransplantation for complex renal tumours. We also studied the role of laparoscopy in these situations. METHODS All patients who underwent renal autotransplantation for renal tumour at our centre were included in this retrospective study. Patient profiles were recorded in(More)
A retrocaval ureter is a rare congenital cause of upper ureteric obstruction that results from entrapment of the upper ureter by the inferior vena cava (IVC) as it courses posterior to the cava. We report an interesting scenario of upper ureteric obstruction secondary to entrapment between twin segments of IVC.
CONTEXT Influence of timing of repair on outcome following laparoscopic reconstruction of lower ureteric strictures AIMS To assess the influence of timing of repair on outcome following laparoscopic reconstruction of lower ureteric strictures in our adult patient population. SETTINGS AND DESIGN Single surgeon operative experience in two institutes.(More)
PURPOSE To narrate our experience with laparoscopic reconstruction of obstructive megaureter (MGU) and assess the intermediate-term outcome achieved. PATIENTS AND METHODS Patients were evaluated in detail including presenting complaints, biochemical profile, and imaging (ultrasonography [USG], diuretic renography [DR], magnetic resonance urography [MRU],(More)
OBJECTIVE The aim was to analyze the operative, postoperative and functional outcome of laparoscopic management of previously failed pyeloplasty and to compare operative and postoperative outcome with laparoscopic pyeloplasty for primary ureteropelvic junction obstruction (UPJO). MATERIALS AND METHODS All patients who underwent laparoscopic management for(More)
OBJECTIVE To compare the operative outcome, morbidity profile, and functional outcome after transperitoneal laparoscopic dismembered pyeloplasty for ureteropelvic junction obstruction in unusual circumstances (intrinsic pathology in anomalous kidneys or unusual extrinsic pathologies; group 1) to the outcome after this procedure in familiar pathologies(More)
CONTEXT Long-term outcome following a laparoscopic reconstruction of ureteral strictures (US) involving solitary renal units (SRU) are scarcely reported. AIMS The aim was to report short-term (1 year) and long-term (5 years) outcomes following a laparoscopic reconstruction of US in a solitary kidney. SETTINGS AND DESIGN Retrospective. MATERIALS AND(More)
A novel hybrid approach, integrating stepwise regression analysis (SRA), adaptive neuro-fuzzy inference system (ANFIS) and capital asset pricing model (CAPM), is addressed in this paper for stock portfolio optimization. The SRA is applied to select some of the features from technical indicators that these selected important features improve the performance(More)
