Background: Total hip arthroplasty (THA) stands as the definitive gold standard treatment for degenerative disorders. Various approaches have been proposed THA, each with its own set of advantages and disadvantages. This study aimed to compare initial functional outcomes lateral posterolateral determine approach superior outcomes. Materials Methods: Through a retrospective cohort study, THA candidates over 1-year period were analyzed. Patients who underwent surgery via or included....

Background: Proximal humeral fractures (PHF) are common orthopedic injuries often associated with osteoporosis. Surgical approaches for PHF fixation, such as the deltopectoral and deltoid-splitting methods, have been a subject of debate. Additionally, patient satisfaction these has not extensively studied among Iranian patients. Materials Methods: A cross-sectional study was conducted on patients treated at referral center in Tehran, Iran, from 2019 to 2021. Two surgical techniques,...

Abstract This paper presents a new approach to determine the optimal location of an Optimal Unified Power Flow Controller (OUPFC) as energy flow controller, under single line contingency (N−1 contingency), satisfy operational decisions. A analysis is performed detect and rank faulted contingencies on basis their severity in electrical transmission systems. Minimization average loadability all lines considered optimization objective function, while network settings are set minimize active...

The main goal of Economic Dispatch (ED) is to determine the output generating unit with least cost while satisfying equality and inequality constraints. Valve-point effect, ramp rate limits, prohibited operation zones (POZs), Multiple-fuel transmission losses make ED a complicated, non-linear constrained problem. Hence, in this paper, new hybrid method based on modified particle swarm optimization genetic algorithm (MPSO-GA) proposed solve such complicated feasibility validated six, ten...

Slip energy recovery induction motor drives are used in high power applications, which by controlling the slip a variable speed drive system is provided. However, poor factor disadvantage of system. Presence sub-harmonics line frequency on stator side one special features these drives. A phase-controlled inverter can absorb reactive from supply and inject low-order current harmonics with relatively amplitudes to supply. This paper simulates harmonic content waveforms various points at...

Abstract Considering the importance of renewable energy sector in distribution systems, operation, and management which are connected to network (DN) form multiple microgrids (MMGs) is crucial reducing cost pollution. Hence, this paper aims propose optimal for MMGs DN. Different objective functions have been taken into account optimization, including cost, pollution reduction, power losses. To design multi‐objective optimization problem, a fuzzy method has adopted simultaneous calculations....

Abstract Introduction Scapular anatomical neck fractures are among the most infrequent shoulder girdle fractures. Only seven radiologically confirmed cases of scapular have been documented in literature to date, which only one case underwent delayed surgery. Case presentation A 34-year-old male Persian patient with morbid obesity was diagnosed a scapula fracture after motor vehicle collision. The radiographic assessment indicated an increase glenopolar angle (73.9°). Due concurrent chest and...

In recent years, because of structure renewal, development, and progressive distribution, many the economical technical characteristics power systems in various parts production, transmission, consumption have been changing. Especially, transmission affected to a great degree increase demand limitation new lines formation. One shortcomings this affair is risk losing stability after turbulence occurrence. The controllability can be increased by FACTS devices. devices Interline Power-Flow...

The application of distributed generation resources and capacitor banks is increasing due to the distribution networks extension also power demand growth. Determining installation location capacity are two important effective factors on network loss performance improvement. If connected in right place network, plants capacitors have different effects such as reduction, voltage profile improvement, reliability augmentation. In this paper, order reduce system loss, simultaneous optimal...

This study aims to investigate the hydrogen production process using an integrated system based on solar energy. includes evacuated tube collector absorb energy as input of system. A parametric analysis was conducted determine most important design parameters and evaluate these parameters' impact system's objective functions. For identifying optimum conditions, multi-objective optimization performed particle swarm (PSO) algorithm. The results obtained from show that increment in mass flow...

Choosing the appropriate treatment approach for a multifocal comminuted open fracture of humerus with severe soft tissue defect is challenging issue, which could be interesting every orthopedic surgeon especially those working in trauma centers.This study described an innovative using titanium elastic nailing to treat defect. In this study, we report 40-year-old Persian female patient whom achieved complete union and skin graft healing by medullary nailing, vacuum dressing, grafting.Elastic...

In this paper, AC optimal power flow combined with UPFC has been used to manage the congestion of transmission lines in a restructured system pool market model. The modeling unified controller (UPFC) adopted based on bipolar model and injection method. To determine an appropriate location for as well set its parameters, approach genetic algorithm suggested. modified IEEE 14-bus is effectiveness applicability proposed method results are discussed.
