Device-to-device (D2D) communication-enabled cellular networks allow cellular devices to directly communicate with each other without any evolved NodeB (eNB). D2D communication aims to improve the spectral efficiency and increases the overall system capacity. For future mobile networks, intelligent radio resource allocation and power control schemes are required to accommodate the increasing number of cellular devices and their growing demand of data traffic. In this paper, a combined resource allocation and power control scheme for D2D communication is proposed. In the proposed scheme, D2D communication reuses the uplink (UL) resources of conventional cellular user equipments (CUEs); therefore, we have adopted single-carrier frequency division multiple access (SC-FDMA) as UL transmission scheme. The proposed scheme uses fractional frequency reuse (FFR)-based architecture to efficiently allocate the resources and mitigate the interference between CUEs and D2D user equipments (DUEs)....

Abstract—Roadside-to-vehicle communications has recently gained significant research attention. The idea is to exploit opportunistically encountered public WLAN APs from vehicles moving on their normal routes. Different aspects of this chal-lenging communication ...

The recent research efforts are focusing on exploring the 802.11 wireless LAN-(WLAN-) based roadside-to-vehicle (R2V) communications. The main concept of the 802.11-based vehicular communications involves encountering the already deployed WLAN access points from the vehicles and using the same for communication purposes. Different works in literature have evaluated the performance of such a challenging scenario from different perspectives, however, very little has been done in modelling this unique kind of communication. In this paper, we show that the previously used models are not applicable in 802.11-based R2V scenario and give a hidden Markov model representation of the same. We evaluate the model parameters based on the data collected from the drive tests. This is a relatively new research direction that has not been rigorously explored before.

In modern parallel adaptive mesh computations the problem size varies during simulation. In this study we investigate the comparative behavior of four load balancing algorithms when the number of processors is dynamically changed during the lifetime of a multistage parallel computation. The focus is on communication and data movement overheads, total parallel runtime and total resource consumption. We demonstrate the main ideas for the case of six adaptive mesh refinement (AMR) applications with different kinds of growth patterns. The results presented are for a 32 processor Intel cluster connected by Ethernet.

According to the report of world health organization (WHO), about 1.27 million people lost their lives in 2009 due to the road accidents and it was the ninth major reason of deaths. The vehicle-to-vehicle communication system (V2V) is one of the solutions to decrease the accident ratios. The existing V2Vs are fixed based on single radio and are inefficient and unreliable especially in the hilly areas due to low SNR and partial coverage. Their performance is degraded in the metropolitans due to dense population and over-burdened traffic routes. Keeping above disadvantages in mind, multiradio access technologies (GSM/GPRS, CDMA, Wi-Fi) based V2V using cognitive radio framework is proposed in this paper. The method introduces an in-vehicle cognitive radio site with the capabilities of spectrum sensing, spectrum decision and spectrum mobility. Experimental results demonstrate that the proposed solution does not overburden the existing networks in affected area and vehicles remain aware of other vehicles even in low SNR by single radio technology and partial coverage areas.

For many decades researchers in the domain of NLP (Natural Language Processing) and its applications like Machine Translation, Text Mining, Question Answering, Information Extraction and Information retrieval etc. have been posed with a challenging area of research i.e. WSD (Word Sense Disambiguation) WSD can be defined as the ability to correctly ascertain the meaning of a word, with reference to the context in which the word was used. Linguistics, has defined context as the passage, sentence or text in which the word appears that is used for ascertaining its meaning. Thus, context is dependent on the POS (Part Of Speech) where the word is used e.g. Adverb, Adjective, Pronoun, Verb and Noun. In the following study we recommend a unique way of WSD based on Context through WordNet, multimodal algorithm that is knowledge based, map-reduce and soft sense WSD.

Femtocells use common cellular air access technologies, but claim to improve system capacity according to Shannon's law by reducing distance between transmitter and receiver and thus improving the signal-to-noise ratio (SNR). Femtocells, however, use the IP network as backhaul architecture instead of the conventional cellular network infrastructure. Thus, femtocell and WiFi infrastructure networks have a lot in common. This raises

We present the results from numerical simulations of turbulent Rayleigh–Bénard convection for an aspect ratio (diameter/height) of 1.0, Prandtl numbers of 0.4 and 0.7, and Rayleigh numbers from $1\ensuremath{\times} 1{0}^{5} $ to $1\ensuremath{\times} 1{0}^{9} $. Detailed measurements of the thermal and viscous boundary layer profiles are made and compared to experimental and theoretical (Prandtl–Blasius) results. We find that the thermal boundary layer profiles disagree by more than 10 % when scaled with the similarity variable (boundary layer thickness) and likewise disagree with the Prandtl–Blasius results. In contrast, the viscous boundary profiles collapse well and do agree (within 10 %) with the Prandtl–Blasius profile, but with worsening agreement as the Rayleigh number increases. We have also investigated the scaling of the boundary layer thicknesses with Rayleigh number, and again compare to experiments and theory. We find that the scaling laws are very robust with respect ...

Нещодавні досягнення в галузі біблійної медіакритики (дослідження функціонування і динамік різноманітних засобів комунікації) пропонують потенціал, що поліпшить наше розуміння референта виразу "гріх на смерть" в 1 Івана 5:16-17. Вчені як давнини, так і сучасності, певно відчули свою ефемерну владу над точною інтерпретацією. Про яку смерть мовиться? Який саме гріх автор має на увазі? Чи може істинний віруючий вчинити "гріх на смерть"? На ці запитання, наразі, неможливо знайти єдиної наукової відповіді. На правду сказати, нещодавно виданий коментар розглядає щонайменше 20 (!) можливих значень. Попри таку безвихідь, ця стаття пропонуватиме шлях, що зважатиме на усні динаміки Iлля Манзюк Богословские размышления № 20, 2018 Вступ Вчені як давніх днів, так і сучасності переконалися у безуспішності своїх намагань остаточно визначити референт "гріха на смерть" в 1 Івана 5:16. Текст говорить: Коли хто бачить брата свого, що грішить гріхом не на смерть, нехай молиться за нього, і Він життя йому дасть, тим, хто грішить не на смерть. Є й гріх на смерть, не про нього кажу, щоб молився. (переклад І. Огієнка). Постають питання: Про який вид смерті мовиться? Про який гріх думається? Чи може істинний віруючий скоїти "гріх на смерть"? На ці запитання, наразі, неможливо знайти єдиної наукової відповіді. 1 Нещодавно виданий коментар розглядає щонайменше 20 (!) можливих рішень. 2 Разом з тим, недавні досягнення в галузі біблійної медіакритики (вивчення функцій і динамік різних засобів комунікації, а головне, усної форми), відкрили нові горизонти дослідження НЗ, що має потенціал рухати дискусію далі вперед. 3 З появою новаторської праці Альберта Лорда і Вільяма Перрі про усну поезію і усну теорію в першій половині 20 століття 4 , науковці закликають до більш широкого визнання усної природи Нового Завіту. 5 Трохи згодом, увага змістилася на вузькість суто "писемних" підходів, на те, що стверджує дослідник усної традиції Джон Майлз Фолі, є уснопохідними текстами. Власне, це написані тексти "які прямо походять чи сягають корінням в усну традицію." 6 Інакше кажучи, застосовувати літературний підхід до текстів, утворених з усної традиції, це те саме, що йти на сильного звіра з голими руками. Все ж, складність правильного самоозброєння полягає у нашій нездібності цілком і повністю охопити широкий спектр застосувань первинної усної форми у суспільстві. Джеймс Данн, у своєму впливовому президентському зверненні 2002 року до Studiorum Novi Testamenti Societas, визначив проблему так: Ми від природи, за звичкою і інстинктивно працюємо у писемній парадигмі. Відповідно, ми не в стані оцінити те, як функціонує неписемна, усна культура. І якщо нам потрібно емфатично увійти в цю культуру, то природно, що ми усвідомлюємо свою писемну парадигму і намагаємося докласти свідомих зусиль, щоб залишити її і вивільнитися з її успадкованої схильності.

Smart grid is a new vision of the conventional power grid to integrate green and renewable technologies. Smart grid (SG) has become a hot research topic with the development of new technologies, such as IoT, edge computing, artificial intelligence, big data, 5G, and so on. The efficiency of SG will be increased by smart embedded devices that have intelligent decision-making ability. Various types of sensors and data sources will collect data of high resolution. One of the vital challenges for IoT is to manage a large amount of data produced by sensors. Sending this massive amount of data directly to the cloud will create problems of latency, security, privacy, and high bandwidth utilization. This issue is addressed by edge computing (EC). In EC, the data are processed at the edge of the network that is near the embedded gadgets. This paper provides a comprehensive review of the smart grid systems, based on IoT and EC. The development in the rising technologies, the framework for EC-...

Lithium–sulfur (Li–S) batteries have a high specific capacity, but lithium polysulfide (LPS) diffusion and lithium dendrite growth drastically reduce their cycle life. High discharge rates also necessitate their resilience to high temperature. Here we show that biomimetic self-assembled membranes from aramid nanofibers (ANFs) address these challenges. Replicating the fibrous structure of cartilage, multifactorial engineering of ion-selective mechanical, and thermal properties becomes possible. LPS adsorption on ANF surface creates a layer of negative charge on nanoscale pores blocking LPS transport. The batteries using cartilage-like bioinspired ANF membranes exhibited a close-to-theoretical-maximum capacity of 1268 mAh g−1, up to 3500+ cycle life, and up to 3C discharge rates. Essential for safety, the high thermal resilience of ANFs enables operation at temperatures up to 80 °C. The simplicity of synthesis and recyclability of ANFs open the door for engineering high-performance ma...

Wireless Sensor Networks are being recently studied to monitor real-time traffic conditions on roads and highways. Idea of using vehicles to convey information from sensors placed alongside roads to the dedicated base stations has also been under scrutiny for some time. In this paper, we argue that a sensor placed on a vehicle instead of a fixed location can effectively sense traffic congestion on the road and report it to the already available WLAN Access Points (APs) instead of the dedicated base stations. This way, instead of deploying series of base stations to collect traffic information, congestion information can be sent over the ISM links between the vehicular sensor nodes and the WLAN APs. This paper investigates, as we call it, the Extended MULE concept by using actual experimental data obtained from the test drives across the city. Our results show that adopting this idea is effective in reporting traffic congestion on the roads.

Vital detection on the basis of Doppler radars has drawn a great deal of attention from researchers because of its high potential for applications in biomedicine, surveillance, and finding people alive under debris during natural hazards. In this research, the signal-to-noise ratio (SNR) of the remote vital-sign detection system is investigated. On the basis of different types of noise, such as phase noise, Gaussian noise, leakage noise between the transmitting and receiving antennae, and so on, the SNR of the system has first been examined. Then the research has focused on the investigation of the detection and false alarm probabilities of the system when the transmission link between the human and the radar sensor system took the Nakagami-channel model. The analytical model for the false alarm and the detection probabilities of the system have been derived. The proposed theoretical models for the SNR and detection probability match with the simulation and measurement results. Thes...

Colorectal cancer is the third most prevalent cancer in terms of incidences and cancer-related deaths. Surgery, chemotherapy, and radiation are the standard therapeutic options for several cancers including colorectal cancer. Phytochemicals or derivatives such as taxol and vincristine have shown efficacy and are widely used for the treatment of multiple cancers. Since the toxicity associated with the standard chemotherapeutic agents still is a major concern for treating colorectal cancer, alternative strategies using herbal products are extensively tested. Curcumin (cur) is a product of the plant, Curcuma longa, which exhibits anti-inflammatory, antiinfectious, and anticancer activities. A wide variety of evidences from numerous studies demonstrated that Cur prevents carcinogenesis, modulates signaling, inhibits angiogenesis and other critical aspects linked to cancer cell survival and proliferation, and induces chemopreventive and anticancer activity against colorectal cancer. Cur also showed improved efficacy of chemotherapeutic agents in combination studies. Bioavailability and distribution, and clearance in tissues, pose some limitations for the therapeutic application of this herbal component. To address such limitations, strategies such as combination with other compounds, synthesis of derivatives, and nanoparticles were tested with some success. Overall, Cur could play a vital role in the prevention and therapy of colorectal cancer.

Soil depth is a major soil characteristic, which is commonly used in distributed hydrological modelling in order to present watershed subsurface attributes. This study aims at developing a statistical model for predicting the spatial pattern of soil depth over the mountainous watershed from environmental variables derived from a digital elevation model (DEM) and remote sensing data. Among the explanatory variables used in the models, seven are derived from a 10 m resolution DEM, namely specific catchment area, wetness index, aspect, slope, plan curvature, elevation and sediment transport index. Three variables landuse, NDVI and pca1 are derived from Landsat8 imagery, and are used for predicting soil depth by the models. Soil attributes, soil moisture, topographic curvature, training samples for each landuse and major vegetation types are considered at 429 profiles within four subwatersheds. Random forests (RF), support vector machine (SVM) and artificial neural network (ANN) are use...

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n1p72 In soccer, an attack begins with ball recovery. Therefore, the consistency of this performance indicator during a match and its balanced distribution in the field zones can be one of the distinct characteristics of successful soccer teams. This study aims to investigate the performance consistency of ball recovery during a match within several time periods (6 periods of 15 min) and zones (four zones). To this end, observational methodology and software Focus X2 were adopted to evaluate 28 matches of semi-final teams at FIFA 2014 including Germany, Argentina, Netherlands, and Brazil in terms of ball recovery frequency. In total, 3222 performances were recorded. All teams in each match and in whole competition had homogeneity of distribution of ball recovery during the time periods (χ23=1.597, p=0.66). The results of time-zone evaluation indicated that Netherlands and Brazil teams did not have performance consistency on all field z...
