Pełny tekst źródłaDevice-to-Device (D2D) communication is a key technology for future wireless networks, allowingdevices to communicate directly without relying on a cellular infrastructure. Millimeter wave (mm-Wave) communication utilizes high-frequency radio, providing very large bandwidths for fast and reliable D2D transmissions. However, mmWave frequencies have high attenuation, requiring devices to have multiple antennas and perform beamforming. The success of beamforming requires beam training. The beam misalignment can impact the performance of the network. To address these challenges, our study focuses on the theoretical analysis of the performance of mmWave D2D communications within the context of Ultra-Reliable Low Latency Communications(URLLC). We use stochastic geometry and queuing theory to evaluate both spatial and temporalvariations in performance from two different perspectives: the instantaneous average properties of the random network and the global stability properties of a dynamic network with random service requests. For the dynamic properties, we focus on the stability condition of D2D network by introducing directional antennas arrays for the D2D users. The network is modeled based on a spatial birth-death process. For the instantaneous properties, we mainly care about the meta-distribution of the network, which is a metric that accounts for the spatial distribution of coverageprobability. We derive the meta-distribution of the effective rate as a statistical latency guarantee for URLLC communications, by considering both the training overhead and misalignment for a D2D network with beamforming. At last, we propose methods to choose the optimal number of antennas and to allocate resource for beam training

Pełny tekst źródłaNext-generation wireless networks are expected to support sensing techniques. Important examples are intelligent transport systems, where vehicles continuously sense environmental changes and exchange information with vehicles or central servers. There are some naive solutions to do both tasks which propose to share the resources between the two. But, the high spectrum and hardware costs of these approaches encourage to integrate the sensing and communication (ISAC) tasks via a single waveform and a single hardware platform. This thesis focuses on information-theoretic ISAC. We review the first information-theoretic model for ISAC in [1] where a statedependent memoryless channel (SDMC) with generalized feedback signals observed at the transmitter (Tx). Our first contribution is to characterize the fundamental tradeoff between communication rates and sensing distortion of statedependent single-Tx two-Rx broadcast channels (BC) that are physically degraded. We also provide inner and outer bounds on the achievable rate-distortion tradeoffs for general BCs. The single-Txs’ optimal sensing strategy is a simple symbol-by-symbol estimator and the optimality of this estimator stems from the fact that the generalized feedback channels and the state-sequence both are memoryless. This is not necessarily the case in setups with more than one Tx. Specifically, for the MAC, we propose collaborative sensing where each Tx first compresses the obtained outputs and inputs to extract state information, then transmits the compression index using a pure channel code to the other Tx. Also, we describe two collaborative ISAC schemes for D2D, based on source-channel separation/Han’s two-way channel scheme and based on joint source-channel coding (JSCC). In both the MAC and the D2D scenario, our ISAC schemes are strictly concave in the rate-distortion pairs and thus also improve over classical time- or resource-sharing strategies

Pełny tekst źródłaAn optical link based on a multiplex of wavelengths at 1.55µm is foreseen to be a valuable alternative to the conventional radio-frequencies for the feeder link of the next-generation of high throughput geostationary satellite. Considering the limited power of lasers envisioned for feeder links, the beam divergence has to be dramatically reduced. Consequently, the beam pointing becomes a key issue. During its propagation between the ground station and a geostationary satellite, the optical beam is deflected and possibly distorted by atmospheric turbulence. It induces strong fluctuations of the detected telecom signal, thus reducing the capacity. A steering mirror using a measurement from a beam coming from the satellite is used to pre-compensate the deflection. Because of the point-ahead angle between the downlink and the uplink, the turbulence effects experienced by both beams are slightly different, inducing an error in the correction. The performance criteria is the minimum detectable irradiance 95% of the time. A fast model, named WPLOT, taking into account pointing errors and their temporal evolution, is proposed to evaluate the minimum irradiance as a function of the ground station parameters and quality of the correction. The model’s results are compared to those obtained with a more physical but requiring more computation power: TURANDOT. A sensitivity study has been realized and led to a sizing of a ground station. The model also enables the generation of time series in order to optimize the forward error correction codes in order to be compliant with the targeted capacity (1Terabit/s by 2025)

Pełny tekst źródłaThe objective of this study was to know the expectations of the patients who have no therapeutic possibilities and who are under palliative care regarding nursing assistance during the dying process, as well as to identify these patients needs related to communication with the nursing team. The data were collected during the first semester of 2005, through half-structured interviews with guided questions, among 39 oncologic patients without healing prognosis, having a limited capacity to perform activities and subjected to palliative chemotherapy in a hospital institution of the city of São Paulo, Brazil. After loyal transcription of the speeches, the data were analyzed according to the methodology of content analysis. From the interviewee speeches six categories emerged that proved the multidimensional suffering of cancer and its treatment, the fact that regardless of the suffering, life goes on; that spirituality and the family while acting as sources of support provide stimulation for confronting an advanced oncologic disease. The interviewees also revealed the nursing assistance which they desire and the role of note which represented the communication and interpersonal relationship for those who face the dying process. Therefore, it can be concluded that the interviewed patients redeemed the value of human relationships based on empathy and compassion as basis for the care they expect, desiring from the nursing professional a technical-scientific ability to perform actions necessary to relieve the suffering, especially an adequate control of pain, empathy and compassionate behavior, well informed and emotionally supportive. Interpersonal communication proved to be an important attribution to palliative care as long as its value has been prominent in the speeches, paying particular attention to the non-verbal signs of the professional for establishing a link of trust, the necessity of compassionate presence, the desire of not focusing the interaction and the relationship only on the disease and death and in its place concentrating on a cheerful verbal communication favoring optimism and good humor.

Pełny tekst źródłaThe growth of mobile telephony in Africa has surpassed the most optimistic forecasts of the operators. Nowadays the interest and the usefulness of the telephone are clearly demonstrated by the practices and this for all the users whatever the social or geographical level. It is highly adapted in several fields, such as trade, health, education, livestock and agriculture, and is not used in the same way in different environments such as rural, peri-urban or urban areas: emerging and developing countries. Some use applications, others just for calls, so the tool is not the same everywhere. Agriculture is one of the activities practiced by more than 80% of the working population in Burkina, with commercial producers in urban and peri-urban areas practicing market gardening and rural people who are more focused on seasonal and fruit production. In order to increase its agricultural production, mirroring the great powers, Burkina Faso is still on a roll of appropriation of mobile technologies in agricultural production. Despite the influence of technical factors (the digital divide), political, social (illiteracy, poverty) and cultural, the use of the mobile phone has developed so quickly, and this because it does not is more the prerogative of the only haves. Its appropriation by small artisans, traders in the economy sector and farmers has gained momentum because they have understood the value of the subscription system by prepaid or postpaid cards at very affordable costs, to the multiple facilities also that offers the mobile phone. The use of the mobile phone remains particular because it is more adopted by the low-income population to reduce their expenses, so save money. In the sense of always contributing to the expansion of the adoption of information and communication technologies (including the mobile phone) efforts are being made by private and public, national and international institutions to promote their access and their usage

Pełny tekst źródłaWith the rapidly growing of the customers' data traffic demand, improving the system capacity and increasing the user throughput have become essential concerns for the future 5G wireless communication network. In this context, D2D communication and FD are proposed as potential solutions to increase the spatial spectrum utilization and the user rate in a cellular network. D2D allows two nearby devices to communicate without BS participation or with limited participation. On the other hand, FD communication enables simultaneous transmission and reception in the same frequency band. Due to the short distance property of D2D links, exploiting the FD technology in D2D communication is an excellent choice to further improve the cellular spectrum efficiency and the users’ throughput. However, practical FD transceivers add new challenges for D2D communication. For instance, the existing FD devices cannot perfectly eliminate the SI imposed on the receiver by the node’s own transmitter. Thus, the RSI which is tightly related to the transmitter power value highly affects the performance of FD transmission. Moreover, the FD technique creates additional interference in the network which may degrade its performance when compared with the half-duplex transmission. Thus, proper radio resource management is needed to exploit the benefits of FD and guarantee the QoS of the users. The works in this dissertation focus on the PA and CA of a FD-D2D network. In particular, this thesis first addresses the PA problem and proposes a simple yet efficient centralized optimal PA framework, and next, it derives the optimal joint PA and CA scheme for an FD-D2D network. A simple sub-optimal algorithm for resource allocation named CATPA, based on CA followed by PA, is also derived and proposed. This dissertation also develops, in the end, an efficient decentralized PA using game theory tools that will be an essential part of future works in the context of distributed radio resource management

Pełny tekst źródłaLn urban or indoor environment, communications are altered by multiple reflections leading to multipath fading on RF signal. Antenna diversity provides an efficient me ans to improve the radio link in these environments. We worked on different compact diversity antennas structures. To compare their performance, we have developed a theoretical methodology for diversity evaluation by introducing new concepts like the referenced diversity gain. This methodology allows choosing an optimized antenna system for a given application. Ln addition to our study on theoretical tools, we developed a test bench in order to quantify the radio link improvement bring by an antenn versity system in terms of BER. Our experimental method for diversity gain evaluation involves a testbench using realistic modulated RF signaIs. It differs from experimental methods proposed in recent previous works. Finally, experimental procedure and first measurement results are detailed in this document

Pełny tekst źródłaThe increasing use of mobile applications leads to a growing demand for higher data-rates and low-cost mobile telecommunication solutions. While 5G networks are still at their early stages, a central role can be played by the mobile satellite telecommunications (Sat-Com-On-The-Move). The frequency bandwidth available at Ku- (10.75-14.5 GHz) and Ka- (18-31 GHz) bands for these applications can be leveraged in order to provide worldwide, high-speed and low-cost internet connections. Companies like SpaceX are actually deploying large satellite constellations required to work at Low Earth Orbits and offer such services. Nevertheless, the price and the form factor of the traditional motorized reflector-based user terminals remain the main bottlenecks in order to make these technologies affordable to the mass-market consumers. The limited operational bandwidth of the radiating elements integrated in their low-profile alternatives (i.e. slotted waveguide antenna arrays) actually obliges to split transmission (Tx) and reception (Rx) in two different panels, keeping a relatively high cost for the end-users. The objective of this thesis is to develop innovative low-cost and wideband antenna solutions, notably microstrip aperture coupled patch and double ridged waveguide antennas, to be respectively realized by standard Printed Circuit Board (PCB) and metal 3-D printing. These antennas are meant to cover the whole Ku- and Ka- band in order to allow the creation low-profile Sat-Com-On-The-Move user terminals able to perform both Rx and Tx using a single antenna panel. A particular attention is given to the possibility to integrate these radiating element in small arrays to be used as unit cell for the realization of larger ones, envisaging the possibility to achieve the levels of gain required by this kind of telecommunications

Pełny tekst źródłaWith the growth of the aviation industry it is necessary to create new technologies that can increase the system capacity without loss in the safety levels. Because of this the CNS/ATM was created, a paradigm that integrates communication, navigation and surveillance technologies with a global air traffic management. For the communications between controllers and pilots, the current system of voice over analog radio is being replaced by a data link, called the Controller-Pilot Data Link Communication (CPDLC). This replacement raises debates between airmen and authorities, demanding a detailed study that proves its effectiveness. Thus, this research aims to evaluate the CPDLC safety when used in Terminal Airspace Areas. For this research, was created a methodology for security assessment using flight, air traffic, and CPDLC simulators combined with a Markov model analysis. The Congonhas airport arrival procedure, located in São Paulo Terminal, was used as reference for this methodology application. The results showed that the current system of voice communication is on the limit of fulfilling the international safety levels for the current demand. However, the data link communication addresses, and in some cases even improve, the safety level for this airspace region.

Pełny tekst źródłaEste trabalho lida com o problema de radiolocalização de terminais em um ambiente de comunicações móveis celulares. Desenvolve-se novas alternativas para a estimação da posição, admitindo-se que as medidas de tempo de chegada (ToA) obtidas no enlace-rádio estão corrompidas por ruído aditivo e apresentam erro médio positivo durante períodos aleatórios, devido à ausência de linha de visada (NLOS) entre terminal e estações radio-bases. Em uma das alternativas desenvolve-se um estimador assintoticamente eficiente do erro de NLOS, sob o critério de mínimos quadrados ponderados (WLS). Para esta estimativa, admite- se o conhecimento a priori do espalhamento temporal do canal, e que o perfil de potência do sinal pode ser calculado por uma média temporal de medidas independentes em um receptor RAKE. O esquema de localização apresentado incorpora também um teste de hipóteses desenvolvido sob o critério de Neyman-Pearson, para detectar, a cada instante de tempo, a ocorrência de transições entre os estados LOS/NLOS do canal. Em outra contribuição do trabalho, as coordenadas do terminal são estimadas recursivamente utilizando-se algoritmos bayesianos, com a dimensão do espaço de estados aumentada para incluir o efeito do erro de NLOS sobre as medidas de ToA. Resultados de simulação obtidos sob diferentes cenários comprovam a eficiência dos esquemas de estimação aqui desenvolvidos, quando comparados à única solução de que se tem conhecimento na literatura. Apresenta-se ainda nesta tese uma análise para o problema de ambigüidade em métodos hiperbólicos de localização, cujo objetivo é identificar a região do plano em que este método fornece duas soluções fisicamente admissíveis. A área desta região é comparada com a área total de triangulação.
This work addresses the radiolocation problem of a moving terminal in a cellular mobile communications environment. New alternatives are developed for position estimation, assuming that the Time of Arrival (ToA) measurements obtained from radio link are corrupted by additive noise and have positive mean error during random periods of time due to the non-line of sight (NLOS) propagation condition between the terminal and base stations. In one of the proposals, an asymptotically efficient WLS estimator of the NLOS error is developed under the Weighted Least Squares criterion. It is assumed that the channel temporal scattering model is known and the mean power delay profile can be evaluated by time averaging independent measurements from a RAKE receiver. The location estimation scheme also includes a hypothesis testing based on Neyman- Pearson approach to detect at each instant of time the LOS/NLOS states transitions. In another contribution, the terminal coordinates are recursively estimated using bayesian algorithms, with the state-space dimension augmented to include the NLOS error effect over ToA measurements. Simulation results obtained under different scenarios show the effectiveness of the estimation schemes developed here when compared to the only alternative known from the literature. An analysis concerning the ambiguity problem in hyperbolic location methods is also presented, aiming to determine the regions where this method gives two physically admissible solutions, and compare them to the total trilateration area.

Pełny tekst źródłaThis thesis will make a comparative analysis of the operation safety of the wire connection to Remote Terminal Unit (RTU) and Programmable Logic Controller (PLC) with bus-controller. The report describes the basic description of the difference between these two systems and will explore which is safer and more economic with consideration to qualification according to Swedish energy companies' guidelines for dam safety (Ridas).Through course literature, ABB Bok, internet web sits and interviews with Skellefteå Kraft AB staff the result of this report have been created.The report results prove that PLC with bus-controller will operate operationally safe and profitable compared to wire connection to RTU. Results also showed that there is nothing which prevents to install bus-controller according to RIDAS but certain features should be installed.

Suffering is considered a problem area for the palliative patient. Existential suffering manifests itself individually and is common in palliative care. The nurse has four responsibilities under the ICN Code of Ethics, which includes promoting health, alleviating suffering, preventing illness and restoring health. Communication is an important tool for adapting nursing based on the unique patient’s needs. Purpose: To investigate the nurse's ability to communicate with patients at the end of life and whether this could help alleviate existential suffering. Method: A general literature study that was created based on a systematic approach with an inductive focus. Results: Communication proved a major significant role in alleviating the suffering of the existentially suffering patient. Important characteristics that were identified were the nurse's communication through relationship and the communication tools: empathic communication, time and moment, a relationship based on trust and the nurse's ability to initiate conversations. Conclusion: The literature study identified several communication tools that could be helpful in communicating with the existentially suffering patient. As a nurse, being able to identify the patient's need to talk, read out the appropriate time and to be able to interpret when there is a need to take a step back was considered important.

The connection of different modules from different manufacturers into a single bus for the exchange of data and control is a challenge for the agricultural machinery Brazilian industry, although this technology is consolidated in automobiles, aircraft and the factory floor. The benefits obtained with digital networks are obvious, but they need implementation of protocols networks. In the agricultural area, the international standard ISO 11783 shows strong potential to become the reference standard for the exchange of data between modules on tractors and agricultural implements. This standard, also known as ISOBUS, is in the advanced stage of development. It contains fourteen documents and its development is supported by groups called \"Task Force\" in Europe, USA, and recently in Brazil. Implementations of this standard are now being presented in the international market, in fairs and demonstrations of application of this technology. Brazil should invest and dominate the technology, to inquire after international compatibility in both the technological point of view as commercial. In this context, this work encourages the national development in applications with ISOBUS standard, presenting two studies of cases, whose modules communicate with equipment market compatible with the standard. These practical experiences complement academic works on this subject, which emerged in recent years in Brazil.

There are many cities like Cleveland which were built to serve a far greater population
than currently inhabits the city. Infrastructure built for 800,000 now services
400,000 leaving creating surplus capacity and derelict spaces; urban voids which
have fallen into disuse. Manufacturing and shipping industries occupy valuable
waterfront space, highways create rifts and large civic public spaces designed
with the best of intentions create vacuums.
Cleveland is not dealing with the issue of growth but with transformation; in its
remaking as a place of mixed communities and neighborhoods. Understanding
the city spatially is the first part of an exploration into devising interventions that
can utilize existing infrastructure, reclaim and re-purpose spaces to generate new
uses and new vitality. This thesis is concerned with identifying an opportunity and
proposing a programmatic and spatial transformation.

Pełny tekst źródłaBakgrund: Palliativ vård har i syfte att lindra lidandet och förbättra livskvalitén hos patienter som har en obotlig sjukdomsdiagnos. Patienter som är i behov av palliativ vård kan oftast uppleva olika dimensioner av smärta. Lidande i form av existentiell smärta kan leda till starka känslor som dödsångest och hopplöshet. Flera studier har påvisat att den existentiella smärtan inte är lika uppmärksammad som övriga dimensioner av smärta och därmed behövs utökad kunskap kring denna form av smärta. Syfte: Syftet med studien var att beskriva sjuksköterskans upplevelse av omvårdnad för patienter med existentiell smärta vid vård i livets slutskede. Metod: En litteraturöversikt genomförd med kvalitativ ansats. Tio artiklar identifierades och analyserades med en tematisk analys. Resultat: Två teman och fyra subteman identifierades. Existentiell omvårdnad med subteman kommunikation mellan sjuksköterska och patient samt personcentrerad vård. Det andra temat var emotionell utmaning med subteman förmedla hopp och bemötande gentemot patienter. Slutsats: Förmedling av existentiell omvårdnad vid existentiell smärta kan anses vara utmanande för sjuksköterskan där fler aspekter och dimensioner bör beaktas, som exempelvis känslor av utmattning och maktlöshet hos sjuksköterskan.
