IN THE MODERN WORLD OF INFORMATION TECHNOLOGY, THE IOT IS OF PARTICULAR IMPORTANCE. THIS TECHNOLOGY HAS MANY BENEFITS SUCH AS REDUCING COSTS AND SAVING TIME AND OBJECTS INTELLIGENCE. IT CAN ALSO BE USED IN VARIOUS FIELDS SUCH AS MEDICINE AND FARMING. HOWEVER, THE DISADVANTAGES OF THIS TECHNOLOGY CANNOT BE IGNORED. THE BIGGEST DISADVANTAGES AND CHALLENGES OF THIS TECHNOLOGY ARE SECURITY AND BIG DATA PROBLEMS. IN IOT, ANY CONNECTED DEVICE CAN BE A POTENTIAL GATEWAY TO THE IOT INFRASTRUCTURE OR PERSONAL DATA. SECURITY AND PRIVACY CONCERNS ARE CRITICAL, BUT WITH THE INTRODUCTION OF THE ISSUE OF COMPLEXITY, THE POTENTIAL RISKS OF THE INTERNET OF OBJECTS, SECURITY VULNERABILITIES AND POTENTIAL VULNERABILITIES HAVE TAKEN ON A NEW FORM OF POSSIBLE RISKS. THESE RISKS APPEAR IN MANY CASES SUCH AS INTEROPERABILITY, COMBINATIONS AND AUTONOMOUS DECISIONS. THIS PAPER DESCRIBES IOT, ITS ADVANTAGES AND CHALLENGES AND INTRODUCES SOME SOLUTIONS TO THESE CHALLENGES. ALSO, ACCORDING TO THE KEY CHALLENGES LIKE THE SECURITY AND BIG DATA ISSUES, IN THIS PAPER, A GENERAL SOLUTION IS PROPOSED FOR THESE ISSUES.

IN THIS PAPER, WE OBTAIN A SIMPLE PROOF OF THE JORDAN-BROUWER SEPARATION THEOREM. THIS PROPOSITION STATES THAT FOR MÌRM A CONNECTED, COMPACT, ORIENTABLE SMOOTH HYPERSURFACE. ITS COMPLEMENT RM-M HAS TWO CONNECTED COMPONENTS, EACH OF WHICH HAS M AS ITS POINT SET BOUNDARY.

A STRUCTURE OF A DIRECT AND RING WAVEGUIDE IS IMPLEMENTED. THIS STRUCTURE HAS A CORE AND A CLADDING. A MICRORING FILTER WAS SIMULATED. BY CHANGING THE CORE WIDTH, THE FREQUENCY OF THE FILTER WAS CONTROLLED. MATERIALS ARE QUARTZ FOR CLADDING AND AGGAS2 FOR CORE. COMSOL 5.2 IS USED FOR SIMULATION.

AGRICULTURE SECTOR IS VITAL SECTOR IN EACH COUNTRY'S ECONOMY AND HAS A CONSIDERABLE RATE OF ENERGY CONSUMPTION. THIS SHOWS THE IMPORTANCE OF ANALYSIS OF ENERGY BESIDE ECONOMICAL CONSIDERATIONS IN THIS SECTOR. IN THIS STUDY CONSUMED AND PRODUCED ENERGY AND PRODUCTIONS COST FOR MAIN CROPS OF BARDSIR CITY (WHEAT, POTATO AND SUGAR BEAT) AND BAFT CITY (WHEAT AND POTATO) IN KERMAN PROVINCE WERE DETERMINED BY USING OF COMPLETELY RANDOM SAMPLING AND INTERVIEWS WITH FARMERS AND THEN INDICES OF NET ENERGY GAIN, ENERGY RATION, ENERGY PRODUCTIVITY AND NET INCOME WERE EVALUATED. RESULT INDICATED THAT THE LOWEST ENERGY RATION WAS RELATED TO POTATO IN BAFT REGION (0.55). IN TWO REGIONS POTATO AND WHEAT HAD NEGATIVE NET ENERGY GAIN AND THIS INDEX WAS POSITIVE ONLY FOR SUGAR BEET (223793.15 MJ/HA). STUDY THE SHARE OF INPUTS FACTORS OF TOTAL INPUT ENERGY INDICATED THAT FERTILIZER AND IRRIGATION HAD THE MOST SHARE OF ENERGY. IN TWO REGIONS, POTATO IN BARDSIR HAD THE MAXIMUM AND WHEAT IN BARDSIR HAD THE MINIMUM NET INCOME. IMPROVING OF FERTILIZER CONSUMPTION AND IRRIGATION METHODS AND TO MECHANIZE THE SUGAR BEET PRODUCTION CAN ARISE ENERGY EFFICIENCY AND FARMER'S INCOME EFFECTIVELY IN THIS PROVINCE.

IN MOST NONLINEAR OPTIC PROCESSES, DUE TO THE INABILITY OF COMPLETE PHASE MATCHING TECHNIQUES, A SIGNIFICANT REDUCTION IN THEIR CONVERSION EFFICIENCY RATES OCCURS. A QUASI-PHASE MATCHING IS A METHOD TO COMPENSATE FOR THE COMPLETE PHASE FAILURE OF THE PHASE WHEN COMPLETE PHASE MATCHING IS INEFFICIENT. THEREFORE, USING A QUASI-PHASE MATCHING, A STATE OCCURS FOR THE SYSTEM IN WHICH THE PHASE MATCHING IS COMPLETE. IN THIS JOB, USING THE OPTIMAL NUMERICAL CALCULATIONS OF THE FLUX STATE, THE PRODUCTION OF THE SECOND HARMONIC OF THE QUASI-PHASE MATCHING WILL BE INVESTIGATED.

AFTER THE INITIAL DESIGN OF EACH AIR STRUCTURE, IN ORDER TO ASSURE THE CORRECT DESIGN PROCESS, THE COMPONENTS OF THE STRUCTURE ARE REQUIRED UNDER THE LOADING TESTS. ONE OF THE MOST IMPORTANT COMPONENTS OF THE STRUCTURE IS THE WING, WHICH ITS DYNAMIC LOADING TEST IS OF PARAMOUNT IMPORTANCE. IN THE STATIC LOADING TEST, THE AERODYNAMIC LOADING, WHICH IS APPLY INTO THE WING BY FORCE DISTRIBUTION, IS CONVERTED TO POINT LOADS AND ENTERS THE WINGS BY THE TEST SYSTEM. ONE OF THE MOST COMMONLY USED SYSTEMS IS THE WHIFFLE TREE SYSTEM. THE THEORY RELATIONS ARE ALSO DISCUSSED IN RELATION TO A LIGHT CRUISE AIRPLANE FOR WHICH A LOADING SYSTEM HAS BEEN CONSTRUCTED FOR THE WING. THE RESULTS OF THE TEST AND THE THEORY ARE COMPARED AND THE RELATIONSHIPS ARE SHOWN.

ADVANCES IN LED TECHNOLOGY HAVE MADE IT AN EXCELLENT SOURCE FOR RESEARCH PURPOSES. SMALL SIZE, LONG DURABILITY AND LONG LIFE, AS WELL AS THE COOLNESS OF THE LAMPS, ARE OPTIONS THAT CAN BE USED AS A GOOD SOURCE OF LIGHT FOR PLANTS. ACCORDINGLY, A POT EXPERIMENT UNDER NON-SOIL CROPPING CONDITIONS IN A GREENHOUSE WAS USED AS A SPLIT PLOT EXPERIMENT BASED ON A COMPLETELY RANDOMIZED DESIGN WITH THREE LIGHT TREATMENTS INCLUDING: NATURAL LIGHT (CONTROL), 60% RED LIGHT+40% LIGHT BLUE AND 90% RED LIGHT+10% LIGHT BLUE AND 2 NUTRITIONAL TREATMENTS INCLUDING: LACK OF SPRAYING WITH CALFOMITE COMMERCIAL FERTILIZER (A MIXTURE OF CALCIUM AND PHOSPHORUS WITH OTHER MICRO-NUTRIENTS) AND SPRAYING WITH A CONCENTRATION OF 2, 000 PER 3 REPLICATES AT THE SITE OF THE RESEARCH GREENHOUSE OF THE FACULTY AGRICULTURE OF FERDOWSI UNIVERSITY OF MASHHAD WAS ESTABLISHED AND IMPLEMENTED. ACCORDING TO THE RESULTS, SUPPLEMENTAL LIGHT AND NUTRITIONAL TREATMENTS (FOLIAR APPLICATION WITH CALFUMITE) HAD NO SIGNIFICANT EFFECT ON FRESH WEIGHT AND FRUIT DRY MATTER. THE DRY WEIGHT OF FRUIT AT 5% PROBABILITY LEVEL WAS INFLUENCED BY SUPPLEMENTARY LIGHT AND COMPLEMENTARY LIGHT AND NUTRITIONAL INTERACTIONS AND INCREASED TREND TOWARD CONTROL TREATMENT. ALSO, THE SUPPLEMENTARY LIGHT HAD A SIGNIFICANT EFFECT ON THE RATIO OF MEAT TO SEED IN THE 5% PROBABILITY LEVEL. THEREFORE, IT CAN BE CONCLUDED THAT THE USE OF SUPPLEMENTARY LIGHT AND NUTRITION CAN IMPROVE THE YIELD OF TOMATO PLANTS AND INCREASE THE AMOUNT OF MEAT THAT CAN BE USEFUL IN BOTH FRESH AND IN VITRO FERTILIZATION.

POLYVINYL ACETATE (PVAC) IS USED AS PAINT IN INDUSTRY, ITS EMULSION AND SOLUTION RADICAL POLYMERIZATION INDICATES A HIGH MOLECULAR WEIGHT DISTRIBUTION, WHILE IT HAS GREATLY LIMITED THE USE OF THIS POLYMER. THE DISTRIBUTION IS REDUCED BY CU/CO CATALYST. THE USE OF POLYMERIC FIBROUS MEMBRANES AND REPLACEMENT OF COBALT ACETYLACETONATE CATALYST WITH DIBUTYLTIN DILAURATE IN MEMBRANE COLUMN, MADE A UNIFIED SYSTEM OUT OF THESE INNOVATIVE ASPECT OF THE CONTROLLED POLYMERIZATION THAT MAKE THE PROCESS VERY ATTRACTIVE IN COST, SAFETY AND NEW IN THE POLYMERIZATION OF VINYLACETATE.

ADVERTISING, USING ICT, SUCH AS SMS, CAN BE EXPANDED CONSIDERABLY IN QUANTITATIVE TERMS AS WELL AS QUALITATIVELY ENHANCED WITH INTERACTIVE INFORMATION SYSTEMS. THE PURPOSE OF THE PRESENT RESEARCH IS TO INVESTIGATE THE EFFECTS OF TECHNOLOGY, ORGANIZATION AND ENVIRONMENT ON THE WILLINGNESS OF COMPANIES TO ACCEPT MOBILE PHONE MARKETING IN FAST FOODS LOCATED IN ISFAHAN. THE PURPOSE OF THIS STUDY IS TO USE A RESEARCH METHOD AND THE METHOD USED IS A DESCRIPTIVE ANALYTICAL METHOD. THE STATISTICAL POPULATION OF THE STUDY CONSISTED OF ALL FAST FOOD COMPANIES LICENSED IN ISFAHAN WITH 500 PEOPLE. THE SAMPLE SIZE, ACCORDING TO THE MORGAN TABLE, IS 217 PEOPLE. A QUESTIONNAIRE OF 45 QUESTIONS IN SECTORS (TECHNOLOGY, ORGANIZATION, ENVIRONMENT AND MOBILE) BASED ON THE LIKERT SPECTRUM WAS USED TO COLLECT DATA. THE VALIDITY OF THE QUESTIONNAIRE WAS FORMAL, WHICH WAS CONFIRMED BY THE PROFESSORS OF UNIVERSITY MANAGEMENT, AND RELIABILITY WAS ALSO CONFIRMED ON THE BASIS OF CRONBACH'S ALPHA IN GENERAL OF 0.84. THE DATA WERE ANALYZED USING AMOS SOFTWARE AND STRUCTURAL EQUATIONS. THE RESULTS INDICATE THAT ALL THE RESEARCH HYPOTHESES WERE APPROVED IN SUCH A WAY THAT THE RELATIVE ADVANTAGE OF THE TENDENCY TO ACCEPT MARKETING, THE COMPLEXITY OF THE TENDENCY TO ACCEPT MARKETING, THE COST OF WILLINGNESS TO ACCEPT MARKETING, SENIOR MANAGEMENT ON THE TENDENCY TO ACCEPT MARKETING, FINANCIAL RESOURCES THE TENDENCY TO ACCEPT MARKETING, THE ABILITY OF THE EMPLOYEE TO ACCEPT THE MARKETING, THE COMPETITIVE PRESSURE OF THE ENVIRONMENT ON THE WILLINGNESS TO ACCEPT MARKETING, THE CUSTOMER'S PRESSURE ON THE DESIRE TO ACCEPT MARKETING AND THE SELLER'S SUPPORT AFFECT THE WILLINGNESS TO ACCEPT MARKETING. BASED ON THIS, IT IS SUGGESTED THAT, GIVEN THAT CUSTOMERS' EXPECTATIONS AND PERCEPTIONS ARE CHANGING OVER TIME, IT IS SUGGESTED THAT THIS SHOULD ALWAYS BE MEASURED AND IMPROVED CONTINUOUS PERCEPTIONS OF CUSTOMERS' PERCEPTIONS AND PERCEPTIONS OF OFFICE SERVICES DELIVERING SERVICE DILIGENTLY, AND AS A RESULT OF SATISFACTION AND SATISFACTION OF VISITORS.

THE GROWTH OF THE INTERNET OF OBJECTS ACROSS THE COUNTRY AND ITS IMPACT ON THE LIFESTYLE OF PEOPLE HAS MULTIPLIED THE NEED FOR PRIVACY AND SECURITY, MAKING IT A MAJOR CHALLENGE. THE PURPOSE OF THIS RESEARCH IS TO MODEL AND EVALUATE THE INTERNET SECURITY OF OBJECTS IN THE COUNTRY; BY DEVELOPING A FLEXIBLE INFRASTRUCTURE, IT CAN DEAL WITH SECURITY THREATS IN A DYNAMIC ENVIRONMENT USING A SUITABLE FRAMEWORK AND DISCOVER THE SCENARIO OF POTENTIAL ATTACKS ON THE INTERNET OF OBJECTS. IN THE PRESENT RESEARCH, BASED ON RESEARCH DONE AND RELIANCE ON INTERNAL CAPABILITIES, A FRAMEWORK FOR PRIVACY AND SECURITY WILL BE PRESENTED TO IDENTIFY POTENTIAL ATTACK PATHS AND REDUCE THE IMPACT OF ATTACKS ON CONSUMERS.

THE INFLUENCE OF MUSIC ON LANGUAGE LEARNING AND PERFORMANCE HAS BEEN THE SUBJECT OF STUDY FOR MANY YEARS. THE PURPOSE OF THE PRESENT STUDY WAS TO INVESTIGATE THE EFFECT OF BEETHOVEN MUSIC ON THE READING COMPREHENSION PERFORMANCE OF TWO GROUPS OF IRANIAN STUDENTS IN AN ENGLISH INSTITUTE IN IRAN. TO THIS END, THE STUDY COMPARED TWO GROUPS OF IRANIAN ENGLISH STUDENTS (N=40) OVER A PERIOD OF A MONTH: ONE WAS TAUGHT READING COMPREHENSION WITH BEETHOVEN MUSIC AND THE OTHER WITH NO MUSIC BACKGROUND WHATSOEVER. THE RESULTS OF THE STUDY SHOWED A SIGNIFICANT DIFFERENCE BETWEEN THE PERFORMANCE OF THE GROUP EXPOSED TO MUSIC AND THE PERFORMANCE OF THE OTHER GROUP NOT EXPOSED TO MUSIC. THE GROUP TAUGHT READING COMPREHENSION WITH BEETHOVEN MUSIC OUTPERFORMED THE OTHER TAUGHT IT WITH NO MUSIC BACKGROUND.

THE PURPOSE OF THIS STUDY WAS TO INVESTIGATE THE RELATIONSHIP BETWEEN CREATIVITY AND WILLINGNESS TO APPLY ADAPTIVE TEACHING PATTERNS IN HIGH SCHOOL TEACHERS IN KERMAN PROVINCE. THE RESEARCH METHOD WAS CORRELATION AND USING A QUESTIONNAIRE. THE STATISTICAL POPULATION CONSISTED OF 140 PHYSICAL EDUCATION TEACHERS IN KERMAN PROVINCE. DUE TO THE LIMITED STATISTICAL POPULATION, THE STATISTICAL SAMPLE WAS SELECTED AS THE TOTAL NUMBER. THE RESEARCH INSTRUMENT CONSISTED OF A STANDARD QUESTIONNAIRE ADAPTIVE TEACHING STYLE OF STYZORG AND FINCH (2006) AND TABRIZ'S HERO CREATOR QUESTIONNAIRE (1393). IN THE PRESENT STUDY, THE RELIABILITY OF THE QUESTIONNAIRE WAS 0.894 AND 0.83, RESPECTIVELY, BY CRONBACH’S ALPHA TEST. PEARSON STATISTICAL TEST WAS USED TO ANALYZE THE DATA. THE FINDINGS SHOWED THAT THERE IS A POSITIVE AND SIGNIFICANT RELATIONSHIP BETWEEN CREATIVITY AND THE WILLINGNESS TO APPLY ADAPTIVE TEACHING PATTERNS IN PHYSICAL EDUCATION TEACHERS OF KERMAN PROVINCE AND ITS COMPONENTS.

CENTRIFUGAL SEPARATORS ACT A MAJOR ROLE IN SEPARATING SUSPENDED PARTICLES WITHIN LIQUIDS AND GASES. IN THIS RESEARCH THE NUMERICAL SIMULATION OF TURBULENT FLOW INSIDE DEHYDRATING CYCLONES USING COMPUTATIONAL FLUID DYNAMICS HAS BEEN DONE. THE AIM OF THIS SIMULATION IS TO COMPARE K-WSST AND LES TURBULENCE MODELS IN UNSTEADY STATES. THE CONTINUITY EQUATION HAS BEEN DISCRETIZED APPLYING FINITE VOLUME METHOD AND IN ORDER TO COUPLE THE CONTINUITY AND MOMENTUM EQUATIONS THE SIMPLE ALGORITHM INTRODUCED BY PATENKAR HAS BEEN APPLIED. IN THIS SIMULATION THE FLOW HAS BEEN ASSUMED AS A 3D SINGLE PHASE INCOMPRESSIBLE VISCOUS FLOW. THE RESULTS OBTAINED DEMONSTRATE THAT LES IS A SUITABLE APPROACH FOR MODELING THE EFFECT OF CYCLONE DIMENSIONS ON THE FLOW FIELD AND PERFORMANCE. THROUGH THIS RESEARCH SOLID WORKS HAS BEEN APPLIED TO CREATE THE 3D MODEL, FLUENT TO ANALYZE THE FLOW, CFD POST AND ALSO TEC PLOT FOR POST-PROCESSING.
