Design considerations of MIMO antennas for mobile phones

YesThe paper presents a new modeling and design concept of antennas using polar- ization diversity of 2 £ 2 and 3 £ 3 Multiple Input Multiple Outputs (MIMO) system that is proposed for future mobile handsets. The channel capacity is investigated and discussed over Raleigh fading channel and compared to a linear/planner antenna array MIMO channel. The capacity is also discussed over three types of power azimuth spectrums. The results are compared to the constraints capacity limits in which the maximum capacity observed

Analysis Composition Weight And Type Of Catches Of Beach Seine Which Operated At Morning And Afternoon In Bungus Selatan Village Bungus Teluk Kabung District Padang City Province Of West Sumatera

The research was conducted on 14 - 21 April 2015 in Bungus Selatan village Bungus Teluk Kabung district Padang city Province of West Sumatera. The purpose of this research was conducted to determine differences in the weight composition and species catch of beach seine operated in the morning and afternoon and looking appropriate operating time to perform better operation beach seine. The method used in this research is the survey method. Catches obtained during the afternoon compared to the catch in the morning, there is no difference in species and weight composition of beach seine catches in the morning and afternoon

An overview on the application of Polymerase Chain Reaction (PCR) in the diagnosis of bacterial infections

This overview describes the principle of polymerase chain reaction as one of the most important techniques used in the diagnosis of bacterial infections due to its reliability, sensitivity and rapidness. It also identifies some of the limitations of the technique as well as some of the bacterial infections that can be diagnosed using the technique which include among others; Tuberculosis (TB), whooping cough, brain abscesses and spinal infection, otitis media with effusion, Mycoplasmal pneumonia, endophthalmitis and bacterial meningitis. Keywords: Polymerase chain reaction, Diagnosis, Bacteria, Infection

Pengembangan Cd Interaktif dengan Model Pembelajaran IPS Terpadu Berbasis Masalah pada Kelas VIII SMP

Interactive CD Media Development in The Social Studies (Ilmu Pengetahuan Sosial) Lessons by Problem-Based Integrated Social Studies Learning Model in Eighth Grade Junior High School. The aim of this research is developing Interactive CD Media in The Social Studies (Ilmu Pengetahuan Sosial) Lessons by Problem-Based Integrated Social Studies Learning Model in class VIII SMPN 9 Pontianak. The methods of this research that is used is descriptive qualitative methods. The data is collected from the result of questionnaires and tests. Those were analized qualitatively. The results of this research showed that: 1) The results of the Interactive CD Media Development in The Social Studies (Ilmu Pengetahuan Sosial) Lessons by Problem-Based Integrated Social Studies Learning Model with criteria very good with mean score of 4.37; 2) the data on students' motivation after learning conducted showed excellent criterion with a mean score of 3.37. 3) students motivation after learning conducted result in criteria very good with the mean score 3.37; 5) learning acquisition showed an increase in the mean pre-test score of 37.00, while the post-test mean score of 69.67 leading to increase in the mean score of 32.67 students. Thus, it can be concluded that the interactive CD media products developed valid and fit use in learning in Integrated Social Studies Lessons in SMP class VIII

Potential Fishing Ground for Tuna (Thunnus SP) Based on Mapping of Sea Surface Temperature Distribution and Catches Data by Using Satellite Imagery of Aquarius in Sumatra Waters

The purpose of this study was to know the potential fishing ground of tuna(Thunnus sp) by mapping distribution of sea surface temperature satellite imageryof Aquarius and catched in waters of West Sumatra and then plotted estimated offishing ground in form of map. The analysis data was conducted in FishingGround Laboratory Faculty of Fisheries and Marine Sciences University of Riau,Pekanbaru. This study using Aquarius satelite imagery data level 3, with a 4 kmspatial resolution. In this study sea surface temperature ranging from 27,040C–30,170C. Tuna was catched dominantly temperature in west season is in range27,090C–29,280C, transition season I 27,040C–30,170C, east season 28,690C–29,820C and transition season II 27,320C–29,540C. The catched with CPUEhighest value 7.5963 kg/day in August. The catches of all tuna is category viablecatch. The potential fishing ground were found ground of Siberut and Siporaisland waters

Proses Belajar Konsep Hereditas melalui Multimedia dalam Pembelajaran Biologi Kelas IX Sekolah Menengah Pertama

: This research is a developmental research that head for, (1) determine what kind of biology multimedia learning in Heredity concept IX Grade at Junior High School, (2) compile learning task in learning Heredity concept, (3) compile biology learning strategy for learning process concept Heredity. Developmental model that used is Borg and Gall developmental model that consist of 10 steps. The developmental steps are research and information collecting, planning, development preliminary form of product, preliminary field testing, main product revision, main field testing, operational product revision, operational field testing, final product revision and dissemination. The material expert validation result gives score for the quality of media learning that developed is quite good). Likewise the media expert valuation the quality of media learning that developed is good, both of them agree that this product can be used in IX grade biology learning process. Trial result support the media and material expert valuation. Likewise the one by one trial, the trial of small group, and field trial gives quite good score
