Coverage, capacity and energy efficiency analysis in the uplink of mmWave cellular networks
In this paper, using the concept of stochastic geometry, we present an analytical framework to evaluate the signal-to-interference-and-noise-ratio (SINR) coverage in the uplink of millimeter wave cellular networks. By using a distance-dependent line-of-sight (LOS) probability function, the location of LOS and non-LOS users are modeled as two independent non-homogeneous Poisson point processes, with each having a different pathloss exponent. The analysis takes account of per-user fractional power control (FPC), which couples the transmission of users based on location-dependent channel inversion. We consider the following scenarios in our analysis: 1) Pathloss-based FPC (PL-FPC) which is performed using the measured pathloss and 2) Distance-based FPC (D-FPC) which is performed using the measured distance. Using the developed framework, we derive expressions for the area spectral efficiency and energy efficiency. Results suggest that in terms of SINR coverage, D-FPC outperforms PL-FPC scheme at high SINR where the future networks are expected to operate. It achieves equal or better area spectral efficiency and energy efficiency compared with the PL-FPC scheme. Contrary to the conventional ultra-high frequency cellular networks, in both FPC schemes, the SINR coverage decreases as the cell density becomes greater than a threshold, while the area spectral efficiency experiences a slow growth region
Coverage Analysis in the Uplink of mmWave Cellular Network
In this paper, we present an analytical framework to evaluate the coverage in the uplink of millimeter wave (mmWave) cellular networks. By using a distance dependent line-of-sight (LOS) probability function, the location of LOS and non-LOS user equipment (UE) are modeled as two independent non-homogeneous Poisson point processes, with each having different pathloss exponent. The analysis takes account of per UE fractional power control (FPC), which couples the transmission of UE due to location-dependent channel inversion. We consider the following scenarios in our analysis: (1) Pathloss based FPC (PL-FPC) which is performed using the measured pathloss and (2) Distance based FPC (D-FPC) which is performed using the measured distance. Results suggest that D-FPC outperforms the PL-FPC at high SINR. Also, the SINR coverage probability decreases as the cell density becomes greater than a threshold
Participatory sensing as an enabler for self-organisation in future cellular networks
In this short review paper we summarise the emerging challenges in the field of participatory sensing for the self-organisation of the next generation of wireless cellular networks. We identify the potential of participatory sensing in enabling the self-organisation, deployment optimisation and radio resource management of wireless cellular networks. We also highlight how this approach can meet the future goals for the next generation of cellular system in terms of infrastructure sharing, management of multiple radio access techniques, flexible usage of spectrum and efficient management of very small data cells

Analysis of Symbol Dan Brown’s Novel “The Lost Symbol”
This thesis studied about Analysis of Symbol Dan Brown’s Novel “The Lost
Symbol.” The problem of this thesis are what symbols does Dan Brown use in the
novel of “The Lost Symbol” and what are the meanings of the symbols. The aim of
this thesis is to find out symbols used by Dan Brown in the novel “The Lost Symbol”
and to describe the meaning of symbol in “The Lost Symbol” novel by Dan Brown.
The researcher used descriptive qualitative method approach to found out and
analyzing the meaning of symbols. Instrument that used by the writer was note
taking. From this instrument, the writer was read the text of novel, and the next writer
was separate the symbol and write down the meaning in paper the location of the
page, the last writer was identify symbol and the meaning in the novel.
In this thesis, the writer found out some symbols according to Jerry’s theory
there are, Personal symbol, consist of: The Order Eight Franklin Square, Melencolia
I, SBB13, Masonic Ring, The Apotheosis of Washington, and The double-headed
phoenix; Cultural symbol, consist of: Statue of Freedom, Hand of the Mysteries,
Masonic Pyramid, Freemason’s Cipher, Great Seal of the United States, Kryptos,
Federal Triangle, Number 33 and Cross or Rose Cross; Universal symbol, the writer
found one symbols: Sacred Book. All symbols used in The Lost Symbol Novel by
Dan Brown is to show as Unite State of America is nation build from freemason
spirit. Masonry is a system of morality,veiled in allegory and illustrated by symbols.
After that the free-mason spirit we can see from rebirth ancient building like, Capitol
building, White House, and Washington Monument.
The result of this research was expected to be useful information to the
students and lecturer, especially people whose concern with symbols. The writer
hopes this thesis can contribute about literature in English and Literature Department
ANALISIS PENERAPAN TEKNOLOGI MEDIA PEMBELAJARAN OLEH GURU DI SMAN 1 SUNGAI RAYA KABUPATEN KUBU RAYA ANALYSIS OF LEARNING MEDIA TECHNOLOGY APPLICATION BY TEACHER IN SMAN 1 KUBU DISTRICT RIVER RAYA
Penelitian ini bertujuan untuk menganalisis proses Penerapan Teknologi Media Pendidikan Oleh Guru Pada Proses Pembelajaran di SMAN 1 Sungai Raya Kabupaten Kubu Raya”. Penelitian ini menggunakan metode deskriptif verifikatif dengan bentuk penelitian studi kasus, dengan jumlah responden sebanyak 84 orang. Hasil penelitian ini menunjukkan bahwa. 1) Model pembelajaran sebagian telah para guru kuasai dan dapat diterapkan dan sebagian lagi belum dapat diterapkan dan dipahami secara utuh, mengingat kurangnya literatur yang tersedia untuk mempelajari model-model pembelajaran tersebut. 2) Strategi pembelajaran sebagian besar sangat diperhatikan dan telah dikuasai dan dapat diterapkan oleh guru dan sebagian lagi belum dapat diterapkan dan dipahami secara utuh mengingat kurangnya pemahaman dalam hal strategi pembelajaran tersebut, mengingat masih ada guru yang kesulitan membedakan antara konsep strategi pembelajaran dengan model, metode dan teknik pembelajaran. 3) Metode pembelajaran sebagian besar sangat diperhatikan, dikembangkan dan dimanfaatkan serta terus dikuasai dan dapat diterapkan oleh guru, dan sebagian lagi belum dapat diterapkan dan dipahami secara utuh, mengingat kurangnya percobaan-percobaan yang mereka lakukan. 4) Media pembelajaran sebagian besar sangat diperhatikan dan telah dikuasai dan dapat diterapkan oleh guru dan sebagian lagi belum dapat diterapkan dan dipahami secara utuh, hanya saja banyak guru yang malas untuk membuat media tersebut, karena kesibukan dan kurangnya bahan atau fasilitas yang tersedia di sekolah atau tempat tinggal para guru yang jauh dari kota. 5) Sumber belajar dan hasil belajar dalam proses pembelajaran sebagian besar sangat diperhatikan dan cukup tersedia dan hasil belajar yang diperoleh siswa sebagian besar sangat memuaskan, walaupun ada beberapa mata pelajaran yang hanya cukup memuaskan.Kata Kunci: Penerapan Teknologi, Media Pembelajaran, Guru
Design of a curry puff making machine
Most of the processes of curry puff making in small scale industry are well known as handmade product where curry puffs are made by using human manpower completely. This certainly needs many human power and skilled operators to increase their production rate at high competitive level. In another side, experienced curry puff maker use the machine that imported from out of our country. This can be a burden for small scale industry player that want to start and continue their small business. This project is to design a curry puff making machine that will help industry player to start their business at low cost. To realize the model of the machine, a systematic approach called product design and development is implemented to ensure the proper design is completed. It is covers the concept development, concept scoring, selection and preliminary final design. Consequently a conceptual model of curry puff machine complete is created. For further step, this conceptual model will be designed in detail and model analysis will be performed to distinguish any design related issues. Curry puff making model is function semi-automatically where it is used to form and crimp the curry puff according to its mould shape. This machine consisting 8 units of plastic mould that capable of producing 8 pieces of curry puff in each operation and would be increased if required. It is use controlled mechanical power to ensure systematic operation is performed. At the same time, the material that used for machine structures are selected based on safety concern for food processing equipment
