Abstract: 

INTRODUCTİ ON: genitourinary hemangiOMAs are rare entities that can affect any portion of the urinary system. The urethra is rarely involved, and most reported cases have occurred in the male urethra. (1) To our knowledge few cases of hemangiOMA occurring in the female urethra have been reported. (2, 3) We report a cavernous hemangiOMA of the urethra in a female patient. . . .

Abstract: 

Orbit Angular Momentum is a novel technology which has been used recently for increasing the channel capacity of communication systems. In the OAM system, the Uniform Circular Array (UCA) has been widely used due to its capability in easy implement of the OAM modes orthogonality. In most of the researches, it is assumed that the transmitter and receiver antenna arrays are aligned with each other in the channel without any reflection. The effect of channel reflection is investigated only on single antenna and Uniform Linear Array (ULA) cases, which according to many difference between the UCA and ULA based OAM systems, the obtained results cannot been used for UCA based OAM system. In this paper, the channel modeling of the UCA based OAM system in presence of the reflection in done. For this purpose, the reflection effect is modeled by a virtual transmitter UCA. Also, the channel matrix in extreme cases is approximated, and the channel capacity using the obtained model is computed. We show that, in the presence of channel reflection, the orthogonality of OAM modes are corrupted, which leads to decreasing the channel capacity. Consequently, a proper pre-coding is needed to prevent capacity loss. We evaluated the obtained results by the simulations.

Abstract: 

CORBA هسته مرکزی مدل مرجع OMA که معماری استانداردی برای سیستم های نرم افزاری مرتبط به هم تعریف می کند، را تشکیل می دهد. معماری OMA، جهت استاندارد کردن مدل ارتباطی نرم افزارهای گسترده که تبادل اطلاعات بین بسته های نرم افزاری از مسائل اصلی آن می باشد، توسط سازمان OMG مطرح شده است. مشخصات استاندارد CORBA بستری را فراهم می کند که این بسته ها بتوانند در یک محیط ناهمگون شامل سخت افزارها، سیستم عامل ها، و زبان های پیاده سازی مختلف از سرویس های یکدیگر بصورت ساختاریافته ای استفاده نمایند. در سیستم های نرم افزاری کنترل پروسه، بالاخص سیستم های کنترل شبکه قدرت، استاندارد شدن رویه تبادل اطلاعات بین بسته های نرم افزاری همیشه مورد بحث واقع شده است. در این سیستم ها معمولا اطلاعات کل سیستم به صورت متمرکز در ماشین های Server اسکادا جمع آوری شده و در اختیار بسته های نرم افزاری نمایش اطلاعات (HMI)، نرم افزارهای مدیریت و تحلیل ( (DMS/EMSو یا GIS گذاشته می شوند.ما در این مقاله با معرفی مدل OMA به بررسیCORBA  جهت استفاده بعنوان بستر پایه ارتباطی در این بسته های نرم افزاری می پردازیم. سپس آن را با فن آوری های مشابه (Java RMI, DCOM) مقایسه نموده و نتایج آزمایش کارآیی یکی از محصولاتی که CORBA را پیاده سازی نموده است را به عنوان نمونه برای ارسال اطلاعات دینامیک پروسه ارائه می کنیم. در آخر استفاده ازCORBA  را به عنوان زیرساختار ارتباطی بسته های نرم افزاری سیستم های کنترل شبکه های برقSCADA) ، HMI،  GISو (EMS/DMS بررسی می کنیم.

Abstract: 

COMMON OBJECT REQUEST BROKER ARCHITECTURE (CORBA), THE CORE OF OBJECT MODEL ARCHITECTURE (OMA), IS A WELL-ESTABLISHED STANDARD FOR COMMUNICATION OF COMPONENT-BASED DISTRIBUTED SOFTWARE SYSTEMS FROM OMG ORGANIZATION. CORBA SPECIFICATION ENABLES THE COMPONENTS TO TRANSPARENTLY ACTIVATE CONNECTION, TRANSMIT REQUESTS AND HANDLE ERRORS IN A HETEROGENEOUS ENVIRONMENT COMPOSED OF DIFFERENT HARDWARE, OPERATING SYSTEMS, AND IMPLEMENTATION LANGUAGES.INTEGRATION OF SOFTWARE COMPONENTS IN INDUSTRIAL PROCESS CONTROL SYSTEMS, ESPECIALLY POWER NETWORK SYSTEMS, HAS ALWAYS BEEN A PROBLEM FOR DIFFERENT VENDORS. IN THESE SYSTEMS, COLLECTED DATA IN SCADA SERVER, NEED TO BE SHARED WITH OTHER APPLICATION SUCH AS HMI, PAS (EMS/DMS) AND GIS IN A REAL-TIME MANNER.IN THIS PAPER, INTRODUCING OMA, WE INVESTIGATE THE USE OF CORBA AS THE BASE OF INFORMATION EXCHANGE BUS FOR PROCESS CONTROL SOFTWARE COMPONENTS. WE COMPARE CORBA WITH COM AND JAVARMI TECHNICALLY AND RELEASE THE REPORT OF THE PERFORMANCE RESULT OF AN IMPLEMENTATION OF CORBA (TAO) FOR TRANSMITTING DYNAMIC PROCESS DATA BETWEEN SERVER AND CLIENTS. AT THE END, WE SUMMARIZE THE APPLICATION OF CORBA FOR INTEGRATION OF POWER NETWORK CONTROL SOFTWARE COMPONENTS (SCADA, HMI, EMS, DMS AND GIS).

Abstract: 

IN THIS STUDY ORDERED MESOPOROUS ALUMINA (OMA) WITH PORE SIZE OF ABOUT 5 NM HAS BEEN USED FOR REMOVAL OF DYES POLLUTANTS FROM BINARY SYSTEMS. DERIVATIVE SPECTROPHOTOMETRY WAS USED FOR SIMULTANEOUS DETERMINATION OF THE DYES CONCENTRATION. THE RESULTS SHOW THAT OMA IS A GOOD ADSORBENT FOR RAPID REMOVAL OF DYES (ESPECIALLY ANIONIC ONES) FROM AQUEOUS SOLUTION.NOWADAYS DISPOSAL OF DYE POLLUTANTS FROM TEXTILE WASTE WATER AND RELATING INDUSTRIES CAUSED SERIOUS ENVIRONMENTAL PROBLEMS. WITHIN VARIOUS METHODS FOR REMOVAL OF POLLUTANTS FROM AQUEOUS SOLUTIONS, SUCH AS ION EXCHANGE, MEMBRANE FILTRATION AND ETC., ADSORPTION IS THE MOST COMMON METHOD. THE SPECIFIC STRUCTURE OF ORDERED MESOPOROUS ALUMINA WHICH MAKES IT BETTER ADSORBENT THAN ALUMINA HAS BEEN CONSIDERED BY MANY RESEARCHERS [1, 2]. IN THE PRESENT STUDY THE SYNTHESIZED OMA WERE USED FOR REMOVAL OF DYES POLLUTANTS FROM BINARY SYSTEMS INCLUDING METHYL ORANGE (MO) WITH BROMOTHYMOL BLUE (BTB), REACTIVE YELLOW (RY) AND METHYL VIOLET (MV). THE ADSORPTION PROCESS WAS FOLLOWED BY UV-VIS SPECTROSCOPY AND THE PROPER WAVELENGTHS WHICH WERE DETERMINED FROM SECOND DERIVATIVE SPECTRA.OMA WAS SYNTHESIZED BY CHEMICAL METHOD USING ALUMINUM ISO-PROPOXIDE AS ALUMINUM SOURCE, F127 TRIBLOCK COPOLYMER AS A PORE DIRECTING AGENT AND ETHANOL AS A SOLVENT. CHARACTERIZATION OF OMA HAS BEEN PERFORMED BY TEM AND XRD TECHNIQUES.OMA IS AN INTERESTING ADSORBENT THAT CAN REMOVE DYE POLLUTANTS FROM BINARY MIXTURE AS WELL AS SINGLE SYSTEMS. IN THE MO-RY BINARY SOLUTION THE COMPETITION BETWEEN MO AND RY MOLECULES FOR ADSORPTION SITES OF OMA CAUSES THAT THE AMOUNT OF ADSORBED DYES FROM THE BINARY SOLUTION BE LESS THAN THE AMOUNT REMOVED FROM THE SOLUTION OF EACH DYES AT THE SAME TIME. THE STRONG INTERACTION BETWEEN THE POSITIVE SURFACE CHARGE OF OMA AND ANIONIC MO CAUSES THAT OMA REMOVES MO FASTER THAN BTB FROM MO-BTB BINARY SOLUTION. ALTHOUGH OMA CANNOT REMOVE MV FROM THE AQUEOUS SOLUTION, THE ATTRACTIVE INTERACTION BETWEEN THE ANIONIC MO AND CATIONIC MV MAY CAUSE THE REMOVAL OF MV BY OMA IN THE BINARY SOLUTION. THE ADSORPTION KINETIC DATA WERE MODELED BY COMPETITIVE SRT MODEL.
