BASIC TYPES OF GAS IN THE DRILLING FLUID, OIL-BASED AND WATER-BASED THERE. IN THIS STUDY, THE EFFECTS OF NANOPARTICLES TO IMPROVE THE RHEOLOGICAL PROPERTIES AND CONTROL THE SAFAB IN THE BASE FLUID AQUEOUS MIXTURE OF BIOPOLYMER AND SURFACTANTS, BY PERFORMING VARIOUS TESTS BY DEVICES VISCOMETER, FILTER PRESS AND STANDARD FILTER PRESS AT HIGH TEMPERATURES AND PRESSURES VIEW HAS BEEN CHECKED. AS WELL AS TO COMPARE THE RESULTS OBTAINED FROM THE USE OF NANOPARTICLES AND UNDERSTAND THE IMPACT OF THEIR PRESENCE, THE TESTING OF A STANDARD PLUG SAFAB CONTROLLER WAS USED AS A CONTROL. AFTER REVIEWING THE DATA FROM THE EXPERIMENTS, IT WAS FOUND THAT THE MIXTURE OF BIOPOLYMER AND SURFACTANTS, THE RHEOLOGICAL PROPERTIES AND CONTROL PROPERTIES OF LOSS AND SAFAB OF FLUID JUST BASED ON POLYMER OR ONLY ON THE BASIS OF A SURFACTANT, AND BETTER PERFORMANCE. IT WAS ALSO OBSERVED THAT NANOPARTICLES PLAY AN IMPORTANT ROLE IN REDUCING THE AMOUNT OF FLUID LOSS CONTROL PLAY SAFAB.

CHECK THE MAIN CAUSE OF TOOTH DECAY CONCRETE BASE (CONCRETE POWER POLES) AND PROVIDING SOUND SOLUTIONS TO REDUCE DEGRADATION OF THE CONCRETE BASE. BECAUSE IN ORDER TO ENHANCE THE SHELF LIFE OF THE CONCRETE BASE OF A LOT OF WORK TO DO AND A LOT OF SOLUTIONS OFFERED. IN THIS PAPER A RELEVANT SOLUTION IS PRESENTED AND DISCUSSED, IN THIS PAPER, WE INVESTIGATE THE CAUSE OF THE DESTRUCTION OF THE CONCRETE BASE AND COLUMN REINFORCEMENT DUE TO GREATER LONGEVITY OF THE BUILDING AND THE TWO ARE COMPARED. BOTH (COLUMN REINFORCEMENT AND CONCRETE PIERS) IN ONE PLACE, A TIME AND ENVIRONMENTAL CONDITIONS ARE COMPARED AND ANALYZED. AND CHECK OUT THE END RESULT OF THIS IS THAT THE MAIN CAUSE OF DEGRADATION OF ELECTRICAL CURRENT THROUGH THE CONCRETE BASE THE CONCRETE BASE AND LOW BASE DIAMETER OF THE CONCRETE BUILDING.

AS IN PREVIOUS STUDIES, MANY STUDIES HAVE INVESTIGATED THE COMPETENCE OF PROJECT MANAGERS, BUT ONLY A FEW LIMITED STUDIES HAVE BEEN CONDUCTED IN THE FIELD OF SUSTAINABLE CONSTRUCTION.THEREFORE, THIS STUDY AIMED TO IDENTIFY THE KNOWLEDGE AND SKILLS REQUIRED BY PROJECT MANAGERS WHO ARE DOING SUSTAINABLE CONSTRUCTION PROJECTS HAVE BEEN CARRIED OUT. IN THIS STUDY, A REVIEW OF PAST RESEARCH, SURVEYS AND INTERVIEWS WITH PROJECT MANAGERS, A BASE OF KNOWLEDGE FOR PROJECT MANAGERS TO COMPETE AND EFFECTIVE IMPLEMENTATION OF SUSTAINABLE PROJECTS CREATED AND THE SKILLS NEEDED BY MANAGERS IN RESPONSE TO THE CHALLENGES OF THE KNOWLEDGE POINT HAS BEEN MADE. THE MOST IMPORTANT AREAS OF KNOWLEDGE MANAGEMENT, SCHEDULING AND PLANNING, STAKEHOLDER MANAGEMENT, COMMUNICATION MANAGEMENT, COST MANAGEMENT AND HUMAN RESOURCE MANAGEMENT, RESPECTIVELY. MOREOVER, THE ANALYTICAL SKILLS NEEDED TO REDUCE CHALLENGES, DECISION MAKING, TEAMWORK, AGENCIES, AND THEIR PROBLEM-SOLVING SKILLS.

چکیده: 

IN THIS PAPER, A NEW EXPERT SYSTEM TO RECOGNIZE NORMAL HUMAN BRAIN, BLEEDING, OR BRAIN TUMOR IS PROVIDED. THE INCIDENCE OF BRAIN TUMORS INCREASED OVER TIME AND IN TERMS OF INCIDENCE AND TREATMENT OF THE DISEASE FACTORS SUCH AS AGE, GENDER, RACE, GEOGRAPHY AND GENETICS WERE CONSIDERED. SOME BRAIN TUMORS SUCH AS GLIOBLASTOMA MAY SUDDENLY OR THROUGH THE DEVELOPMENT OF MALIGNANT PROGRESSION ARISE FROM THE LOWER CLASSES. THEREFORE, THE DIAGNOSIS OF A BRAIN TUMOR AT THE RIGHT TIME PLAYS A VERY IMPORTANT ROLE. THIS EXPERT SYSTEM USING FUZZY LOGIC, WHICH INCLUDES THE SUBDIVISION OF THE CONSTRUCTION PHASE, THE INFERENCE ENGINE, AND DEFUZZIFICATION ARE RULES. INPUT SYSTEM PROTEIN, RED BLOOD CELLS, LYMPHOCYTES, NEUTROPHILS AND EOSINOPHILS AND OUTPUT A DIAGNOSIS OF THE PATIENT'S CONDITION IN ONE OF THREE MODES: NORMAL, BLEEDING AND BRAIN TUMORS.

A NEW BIVARIATE BETA DISTRIBUTION CAPABLE OF PROVIDING BETTER THAN ALL ITS COMPETITIORS IS INTRODUCED. VARIUS REPRESEN TATIONS ARE DERIVED FOR ITS PROUCT MOMENTS, MARGINAL DENSITIES, MARGINAL MOMENTS, CONDITIONAL DENSITIES AND CONDITIONAL MOMENTS. THE METHOD OF MAXIMUM LIKELIHOOD IS USED TO DERIVE THE ASSOCIATED ESTIMATION PROCEDURE. APPLICATIONS TO SIX BIVARIATE DATA SETS ARE ILLUSTRATED.

WITH THE INCREASED USE OF WIND TURBINES IN THE POWER GRIDS, POWER QUALITY STUDY THESE NETWORKS IS CONSIDERED A SERIOUS THING. FLICKR DISTRIBUTION NETWORKS INCLUDE MANY FACTORS THAT ARE WIND TURBINES, INCLUDING WIND PROFILE (WIND SPEED AND WIND DIRECTION). IN THIS STUDY, WE SHOW THAT USING NON-LINEAR CONTROLLER IN THE WIND TURBINE GENERATOR STATOR VOLTAGE FLICKER ON THE NETWORK WILL BE REDUCED. IT ALSO CARRIED OUT A COMPARISON BETWEEN THE CONTROLLERS, LINEAR AND NON-LINEAR CONTROLLER IS DETERMINED NON-LINEAR CONTROLLER NETWORK WILL BE MORE EFFECTIVE IN REDUCING THE VOLTAGE FLICKER.
