The evolved multimedia broadcast multicast service (eMBMS) system was developed to achieve higher spectrum efficiency on video traffic delivery over the long term evolution (LTE) networks. As an integrated component of LTE, eMBMS can be deployed with great flexibility using existing LTE infrastructure. However, current designed as a supplementary subsystem, and has limited capability deliver high-quality broadcast-type services in efficient manner. This paper first studies limitations when...
Air quality is an essential factor for human health and ecosystem balance, but in regions like Petroșani Mountain Depression, air pollution continues to be a significant challenge. This area, marked by decades of coal mining, confronted with high concentrations pollutants, influenced activities the specific geography climate. study aims compare instrumental measurements snow sample analysis, as sustainable alternative method. Specifically, it examines spatiotemporal distribution evolution...
This paper studies possible physical layer enhancements to the Long Term Evolution (LTE) evolved Multimedia Broadcast Multicast Service (eMBMS) system improve its spectrum efficiency and service quality using channel bonding of wide band Radio Frequency (RF) transmission, non-orthogonal multiplexing, e.g., Layered Division Multiplexing (LDM), larger Cyclic Prefix (CP) duration cell size. Single Network (SFN) operation, transmitter spacing co-existence broadcasting, multicasting unicasting...
In addition to the traditional TDM/FDM, advanced television systems committee (ATSC) 3.0 next generation digital TV standard has adopted state-of-the-art coding and modulation, as well new layered division multiplexing (LDM) technology. The ATSC system is able provide higher data throughput, more robust reception, better spectrum efficiency, flexible service combinations in one RF channel with different robustness reception conditions. Due adoption of a two-layer LDM, coverage for very from...
The restructuring of the mining sector in Jiu Valley basin context decarbonization has as its main goal reduction atmospheric pollution. Despite fact that previous studies suggest an overall improvement air quality a result this process, most ignore lack immediate alternative to use coal primary energy resource both locally and regionally. This alternatives been found have negative influence on through noxious gases Particulate Matter released into atmosphere following burning some fuels,...
Delivering local content in terrestrial digital TV (DTV) single-frequency-networks (SFNs) is of great interest to broadcasters, which can support business cases such as news, location-based applications and targeted advertisements. The recently adopted Layered-Division-Multiplexing (LDM) technology offers a new solution achieve high-throughput insertion from any transmitters, at anytime, with flexible coverage areas. To the services delivered using LDM, receivers need estimate specific...
Analyzing and reducing the possible effects of air pollution on human health became important issues for improving quality life in urban areas.Particulate matters (PM) are pollutants with a potential impact vulnerable people (e.g., children, elderly) non-vulnerable as well.The level PM is mainly influenced by concentration parameters such meteorological conditions synergic other pollutants.Different clime scenarios have been developed to model dispersion generated Caprisoara tailing pond,...
The ATSC 3.0 next generation digital TV standard adopts state-of-the-art coding and modulation, as well the new Layered Division Multiplexing (LDM) technology in addition to traditional TDM/FDM. It is a very flexible system capable of combining different services one RF channel with robustness reception conditions. coverage for from legacy one-tower-one-coverage 1.0 system. With enabling technologies, can greatly increase coverage/service areas, reduce distance between co-channel...
3GPP is currently studying the improvement on LTE eMBMS system to provide more capabilities and flexibilties delivering multicast/broadcast services using infrastructure. This paper investigates performance of an improved layered-division-multiplexing (LDM) technology longer cyclic prefix (CP). The link-layer two-layer LDM in first investigated with extensive computer simulations. Coverage analysis then conducted future different (CP) lengths, allow efficient deployment...
Humanity is a fossil-fueled civilization with large influence on the environment. The World Health Organization (WHO) has pointed out that air pollution now single biggest environmental threat to human health. quality in Petroșani, traditional mining region from Jiu Valley bituminous coal basin, Romania, rarely debated; however, it not often investigated. In this paper, main sources of Petroșani are identified and performed measurements emphasize area its transit road. monitoring program set...
The rapid development of science and technology, the restructuring mining extraction industry, bring about profound changes in structure complexity technological equipment used mining. In this paper, Reliability Centered Maintenance (RCM) method has been applied to analyze components KSW-460NE shearer machine, which fails quite frequently. cutter drums do not match from a constructive point view, concrete operation conditions, alongside picks (being direct contact with coal hard inclusions)...
Livezeni is one of the few active remaining collieries from Jiu Valley, in Meridional Carpathian Mountains. Mining waste facilities classification introduced according to Romanian technical prescription PT-C 39. Preliminary geotechnical studies on basement rocks and material are necessary define maximum height slope angle for ensuring stability dump. The first step supposes modeling morphology area based various information sources. decision shape geometry dump could be taken geotechnical,...
Ubiquitous electrocardiography (ECG) sensing with wireless connectivity will be a solid alternative to conventional in-hospital healthcare surveillance. This paper presents prototype for long-term ECG measurement equipment using an IoT environment over collaborative diagnosis network. We propose vision of working on two major paths designing device surveillance: the design path and decision path. The is made from sensors design, analog front-end gateway application, cloud application....
Abstract Geological models are built to serve various purposes (e.g. reserve evaluation, rock stability analysis, etc.). Several software packages dedicated geological modeling and analysis currently available. The paper presents the workflow for performed with Slide3 from Rocscience. An important step is build 3D model both perspective of geometry properties. Doing this in not an easy task reason, we turned GEOVIA Surpac. steps were exemplified northern area Ruschita marble deposit.
In this paper we present network-centric and user- centric routing mechanisms designed for the wireless world initiative new radio (WINNER) multi-hop cellular air interface. We study pros-and-cons of each mechanism describe interactions between main resource management (RRM) functionalities.
There are several situations in which it is necessary to clarify the types of coal that enter into composition mixtures: technical expertise and/or establishing nature some wastes, often from old stockpiles, order eliminate them. The proposed method based on identification and description those mineralogical-petrographic physico-chemical properties whose pursuit can lead a diagnosis differentiation types. Systematic analysis involves first stage different present sample by mineralogical...
