Random Access Protocols with Collision Resolution in a Noncoherent Setting

Wireless systems are increasingly used for Machine-Type Communication (MTC), where the users sporadically send very short messages. In such a setting, the overhead imposed by channel estimation is substantial, thereby demanding noncoherent communication. In this paper we consider a noncoherent setup in which users randomly access the medium to send short messages to a common receiver. We propose a transmission scheme based on Gabor frames, where each user has a dedicated codebook of M possible codewords, while the codebook simultaneously serves as an ID for the user. The scheme is used as a basis for a simple protocol for collision resolution.Comment: 5 pages, 3 figures; EDIT: A version of this work has been submitted for publication in the IEEE Wireless Communication Letters Journa

Lifting from the Deep: Convolutional 3D Pose Estimation from a Single Image

We propose a unified formulation for the problem of 3D human pose estimation from a single raw RGB image that reasons jointly about 2D joint estimation and 3D pose reconstruction to improve both tasks. We take an integrated approach that fuses probabilistic knowledge of 3D human pose with a multi-stage CNN architecture and uses the knowledge of plausible 3D landmark locations to refine the search for better 2D locations. The entire process is trained end-to-end, is extremely efficient and obtains state- of-the-art results on Human3.6M outperforming previous approaches both on 2D and 3D errors.Comment: Paper presented at CVPR 1

The impact on the banking system from the accession of Macedonia in the EU

The aim of this paper is to examine the impact on the banking system from the accession of Macedonia in the EU. EU enlargement is a complex process with enormous impact on the economy of the new member countries. The financial system of the new member country, and the banking system as a part of it, faces with the challenge of integration in the EU financial system. The best evidence of the EU accession impact on the banking system is the analysis of the basic characteristics of banking systems on the countries that became members in the last 20 years. The future banking development in new EU member countries will very likely follow some main patterns known from the old EU members. In a way banks from candidate countries can see their own future by observing the current developments in Western European banking. The process of restructuring in the banking system through consolidation which lead to increased concentration was one of the main drivers of changes. The existence of this process in new EU countries will be examined together with the structure of Macedonian banking system. It is important to examine whether significant efficiency improvements were achieved in the banking systems of the new EU countries and are they result from the bigger market power or some other factor. Also, there were changes in the funding sources of the banks from the new EU countries with a lot of potentials for alternative funding possibilities. The financial crises made these potentials to evaporate, but on long term horizon, those opportunities will appear again. The low level of financial intermediation in new EU countries leaves space for increasing the range of financial services and their scope. Associated with the previous, a further enlarge of the market share on non-bank financial intermediaries in new EU members can be expected

UPAYA TUTOR DALAM MENINGKATKAN KECERDASAN KOGNITIF ANAK USIA DINI MELALUI SENTRA BALOK DENGAN PENDEKATAN BEYOND CENTRE AND CIRCLE TIME (BCCT

Upaya Tutor dalam meningkatkan kecerdasan kognitif Anak Usia Dini melalui sentra balok dengan pendekatan Beyond Centre and Cirle Time (BCCT), di Kelompok Bermain Wajar Binaan SKB Kota Gorontalo adalah program untuk Pendidikan Anak Usia Dini untuk membangun pengetahuannya dari pengalamannya sendiri dengan lingkungan, karena pengetahuan datang dari tindakan. Perkembangan kognitif sebagian besar bergantung kepada seberapa jauh anak aktif memanipulasi dan aktif berinteraksi dengan lingkungannya. Tujuan penelitian ini yaitu (1) Untuk mengetahui pengelolaan PAUD binaan SKB Kota Gorontalo, (2) Untuk mengetahui upaya tutor PAUD dalam meningkatkan kecerdasan kognitif Anak Usia Dini melalui sentra balok dalam pendekatan BCCT di SKB Kota Gorontalo, (3) Untuk mengetahui kecerdasan kognitif Anak Usia Dini yang berkembang melalui sentra balok dengan pendekatan BCCT di SKB Kota Gorontalo. Kajian Teori dalam penelitian ini di antaranya mengenai Pendidikan Anak Usia Dini (PAUD), dan Konsep Pendidikan Anak Usia Dini. Metode penelitian yang digunakan yaitu metode deskriptif dengan pendekatan kualitatif, adapun teknik pengumpulan data adalah wawancara, observasi, studi literatur dan dokumentasi. Subjek penelitian adalah pengelola, staf dan tutor PAUD Wajar I Binaan SKB Kota Gorontalo. Hasil penelitian: 1) Pengelolaan program PAUD binaan SKB kota Gorontalo adalah merintis program PAUD dengan kegiatan: mengembangkan model program PAUD dan melaksanakan pendidikan, dan pelatihan, serta meningkatkan keterampilan pendidik dan tenaga PAUD. 2) Upaya tutor dalam meningkatkan kecerdasan kognitif adalah: mengembangkan pengalaman belajar dengan menggunakan sentra balok dan menggali kebermaknaan dari penggunaan balok, lebih dikembangkan untuk pengetahuan. 3) Untuk peningkatan kemampuan kognitif anak usia dini adalah agar anak usia dini memiliki kesempatan lebih luas untuk bereksplorasi dan menggali kemampuan kognitifnya dalam pemahaman proses dan keterampilan untuk membedakan satu balok dengan lainnya, dan balok dapat dimanfaatkan sebagai alat berkomunikasi dan berinteraksi secara wajar. Adapun dilihat dari permasalahan, simpulannya adalah Pertama, Proses pengelolaan PAUD binaan SKB Kota Gorontalo, yaitu dapat meningkatkan perluasan, dan pemerataan akses layanan PAUD melalui penyelenggaraan PAUD yang mudah dan murah tetapi bermutu, meningkatkan kesadaran, kemampuan dan partisipasi kepada masyarakat di bidang PAUD, agar lebih memahami arti pembelajaran dan permainan sebagai kegiatan yang akan berpengaruh dan bermakna untuk kehidupannya. Mengembangkan model pengembangan program PAUD, melaksanakan pendidikan dan pelatihan serta meningkatkan keterampilan pendidik dan tenaga kependidikan. Kedua untuk mengetahui upaya tutor PAUD dalam meningkatkan kecerdasan kognitif anak usia dini melalui sentra balok dengan pendekatan BCCT di SKB Kota Gorontalo semua tutor sudah memahami perkembangan anak usia dini dan kebutuhan belajarnya, hal ini ditandai dengan pemahaman tentang perkembangan kecerdasan kognitif anak. Ketiga untuk mengetahui kecerdasan kognitif anak usia dini yang berkembang melalui sentra balok dengan pendekatan BCCT di SKB Kota Gorontalo, anak usia dini di PAUD Wajar I telah mengenali ciri-ciri balok dari warnanya, bentuknya, ukurannya dan berat/volumenya karena anak sudah dapat mengenali dan menghafal ciri-ciri balok tersebut

Causes and Effects of The Informal Economy – The Case of Macedonia

Republic of Macedonia (RM) has high level of informal economy activity. It accounts for about 35- 40% of GDP. It has a direct influence to the main indicators, categories and instruments for macroeconomic planning and regulation. By using qualitative, descriptive, statistic and comparative methodologies, this research attempts to locate causes and consequences of informal economy in RM. It also presents different ways for measurement of the size of informal economy and understands the basic characteristics of the Macedonian case in order to present well‐grounded policy recommendations. The main finding of the paper is that the informal economy in The RM is a multifaceted phenomenon and the most efficient manner to remove the causes for the occurrence and presence of the informal economy is the improvement of the institutional frame in the country. There is a need for directly focused Government measures that would precipitate the integration of the informal economy in the formal sector, once the right conditions are put in place. The main recommendation that this paper promotes is directed towards activi ties and measures of the authorities for removing the reasons of informal economy appearance. Another recommendation is for the Government to increase the speed for redefining its role on the market. There is a need for widening the awareness of all busine ss players for the necessity of playing by the rules as well as for enforcing the institutional framework, legal order, moral values and the motivators of the countr y‘s functional economy
