Abstract The MATLAB is a technical computing language used in a variety of fields, such as control systems, image and signal processing, visualization, financial process simulations in an easy-to-use environment. MATLAB offers "toolboxes" which are specialized libraries for variety scientific domains, and a simplified interface to high-performance libraries (LAPACK, BLAS, FFTW too). Now MATLAB is enriched by the possibility of parallel computing with the Parallel Computing ToolboxTM and MATLAB Distributed Computing ServerTM. In this article we present some of the key features of MATLAB parallel applications focused on using GPU processors for image processing.

Introduction. This article is devoted to legal regulation of digital assets turnover, utilization possibilities of distributed computing and distributed data storage systems in activities of public authorities and entities of public control. The author notes that some national and foreign scientists who study a “blockchain” technology (distributed computing and distributed data storage systems) emphasize its usefulness in different activities. Data validation procedure of digital transactions, legal regulation of creation, issuance and turnover of digital assets need further attention.Materials and methods. The research is based on common scientific (analysis, analogy, comparing) and particular methods of cognition of legal phenomena and processes (a method of interpretation of legal rules, a technical legal method, a formal legal method and a formal logical one).Results of the study. The author conducted an analysis which resulted in finding some advantages of the use of the “blockchain” technology in the sphere of public control which are as follows: a particular validation system; data that once were entered in the system of distributed data storage cannot be erased or forged; absolute transparency of succession of actions while exercising governing powers; automatic repeat of recurring actions. The need of fivefold validation of exercising governing powers is substantiated. The author stresses that the fivefold validation shall ensure complex control over exercising of powers by the civil society, the entities of public control and the Russian Federation as a federal state holding sovereignty over its territory. The author has also conducted a brief analysis of judicial decisions concerning digital transactions.Discussion and conclusion. The use of the distributed data storage system makes it easier to exercise control due to the decrease of risks of forge, replacement or termination of data. The author suggests defining digital transaction not only as some actions with digital assets, but also as actions toward modification and addition of information about legal facts with a purpose of its establishment in the systems of distributed data storage. The author suggests using the systems of distributed data storage for independent validation of information about activities of the bodies of state authority. In the author’s opinion, application of the “blockchain” technology may result not only in the increase of efficiency of public control, but also in the creation of a new form of public control – automatic control. It is concluded there is no legislation basis for regulation of legal relations concerning distributed data storage today.

ANALISIS PENGARUH TINGKAT VOLUME DAN JENIS KENDARAAN TERHADAP KONSENTRASI PARTICULATE MATTER (PM10) (STUDI KASUS: JL. SUTAN SYAHRIR, JL. AHMAD YANI DAN JL. KOM. YOS. SUDARSO KOTA PONTIANAK)

ABSTRAK Perkembangan Kota Pontianak yang semakin pesat, ditambah dengan perkembangan penduduk yang semakin meningkat, telah membuat sistem transportasi jalan raya mengalami tingkat kompleksitas yang tinggi , salah satu dampak yang ditimbulkan adalah pencemaran udara perkotaan. Particulate Matter (PM10) merupakan salah satu bentuk zat pencemar yang disebabkan oleh sektor transportasi tersebutserta dapat menyebabkan gangguan kesehatan khususnya pada sistem pernapasan. Oleh sebab itu penelitian ini dilakukan untuk mengetahui tingkat konsentrasi partikulat udara (Particulate Matter (PM10)) khususnya di Jalan Sutan Syahrir, Jalan Ahmad Yani dan Jalan Kom. Yos. Sudarso Jeruju Kota Pontianak. Ketiga lokasi penelitian tersebut dipilih untuk mewakili peruntukkan tata guna lahan yang berbeda yaitu Jalan Sutan Syahrir berlokasi di pinggiran kota, Jalan Jend. Ahmad Yani berlokasi di tengah kota, dan Jalan Kom. Yos. Sudarso Jeruju yang berlokasi di kawasan industri. Data yang digunakan merupakan data sekunder yang didapat dari BLHD Provinsi Kalbar yaitu data volume kendaraan yang melintas pada ketiga jalan tersebut. Jenis-jenis kendaraan dibagi menjadi 4 golongan yaitu golongan 1 (sepeda motor), golongan 2 (sedan, angkot, pickup), golongan 3 (bis mikro, bis), golongan 4 (truck 2 as 4 roda, truck 2 as 6 roda, truck 3 as, truk 4 as, trailer).Metode penelitian yang digunakan terbagi menjadi 2 bagian, yaitu perhitungan (perhitungan beban laju emisi transportasi dan konsentrasi Particulate Matter (PM10) dengan rumus dispersi Gaussian untuk Line Source serta analisis korelasi data untuk memperoleh hubungan antara jumlah kendaraan dengan konsentrasi Particulate Matter (PM10) menggunakan aplikasi SPSS 16. Dari hasil analisis, bahwa jenis kendaraan golongan 1 memiliki kontribusi yang paling besar terhadap konsentrasi Particulate Matter (PM10) yaitu dengan konsentrasi terbesar yaitu 901425,466 dimana nilai konsentrasi tersebut melebihi Ambang Batas Baku Mutu Udara Ambien Nasional yaitu 150 , hal ini dikarenakan sepeda motor memiliki jumlah yang paling banyak apabila dibandingkan dengan kendaraan lain di ketiga jalan tersebut. Kendaraan golongan 2 memiliki jumlah terbanyak kedua diikuti dengan golongan 4 dan 3. Maka dapat disimpulkan bahwa jumlah kendaraan total memang mempengaruhi konsentrasi Particulate Matter (PM10) pada Jalan Sutan Syahrir, Jalan Jend. Ahmad Yani dan Jalan Kom. Yos Sudarso dilihat dari hasil korelasinya yang mendekati nilai 1 (positif kuat) yaitu 0,963 dengan menggunakan aplikasi SPSS 16. Kata Kunci :Particulate Matter (PM10), Golongan Kendaraan, Korelasi.
