In this paper, we study a dynamic pricing and energy consumption scheduling problem in the microgrid where service provider acts as broker between utility company customers by purchasing electric from selling it to customers. For provider, even though is an efficient tool manage microgrid, implementation of highly challenging due lack customer-side information various types uncertainties microgrid. Similarly, also face challenges their uncertainty retail electricity price. order overcome...
Prior studies have demonstrated that the pineal hormone, melatonin, can stimulate chloramphenicol acetyltransferase activity in <i>Drosophila</i> SL-3 cells transfected with a reporter construct containing response element of rat bone sialoprotein (BSP). Based on these findings, were performed to determine whether melatonin could similarly modulate expression BSP two cell lines, MC3T3-E1(MC3T3) pre-osteoblast and osteoblast-like osteosarcoma 17/2.8 cell. Initial MC3T3 grown presence 50 nm...
Abstract Aims: The objective of this study was to characterize the inhibitory effects Weissella cibaria isolates on volatile sulphur compounds (VSC) production both in vitro and vivo. Material Methods: We isolated identified three hydrogen peroxide‐generating lactobacilli from children's saliva, assessed their VSC Fusobacterium nucleatum proliferation. Clinical studies were conducted with 46 subjects order measure mouth air. Results: These as W. . inhibited by F. ( p <0.05). concentration...
Electric vehicles (EVs) will play an important role in the future smart grid because of their capabilities storing electrical energy batteries during off-peak hours and supplying stored to power peak hours. In this paper, we consider a system with aggregator multiple customers EVs propose novel electricity load scheduling algorithms which, unlike previous works, jointly for appliances trading using EVs. Specifically, allow determine how much purchase from or sell while taking into...
We study an opportunistic subchannel scheduling and transmission mode selection problem for the OFDMA system with device-to-device (D2D) communication. allow D2D users to opportunistically select its between two modes: direct (direct one- hop transmission) indirect through BS (indirect two-hop transmission). develop a framework which can be modeled as scheduling, enables our reduced problem. formulate stochastic optimization that aims maximize average sum-rate of system, while satisfying...
This study examined the contribution of leisure participation and satisfaction on experience stress-related growth (SRG). Some types activity may be beneficial for SRG under certain circumstances. In addition, positively related to experience. The participants this were 318 undergraduate students at an eastern Canadian university. results indicated that frequent in civic activities statistically significant predictors SRG. findings provided further evidence positive experiences specific not...
Purpose – The purpose of this paper is to be limited provide an overall economic structure linked with a particular hospitality industry by identifying the relations between two hotel industries and other within state in USA. Design/methodology/approach analyses output, labor income employment multipliers from input–output system were performed using IMPLAN 3.0 software. study attempted compare hotel/motel (industry code 411) accommodations 412) top ten averages each set estimate relative...
Improvements in resolution of exposure systems have not kept pace with increasing density semiconductor products. In order to keep shrinking circuits using equipment the same basic resolution, lithographers turned options such as double-patterning, and moved beyond model-based OPC search for optimal mask patterns. Inverse Lithography Technology (ILT) is becoming one strong candidates 32nm below single patterning, low-k1 lithography regime. It enables computation optimum patterns minimize...
In this paper, we analyze the throughput of IEEE 802.15.4 medium access control (MAC) protocol with considering both contention period (CAP) and free (CFP). We first CSMA/CA algorithm in CAP using a Markov chain guaranteed time slot (GTS) request packets for CFP. And provide an analytical model GTS allocation CFP results CAP. Numerical show that ratio length to affects system.
In this paper, we study a joint opportunistic subchannel and power-scheduling problem in relay-based orthogonal frequency-division multiple-access (OFDMA) networks. most previous works on networks, immediate relaying at relay stations (RSs) without allowing scheduling RSs was considered. Under strategy, each RS should transmit the received data from base station (BS) to corresponding mobile (MSs) immediately within single time slot, thus, effective rate of two-hop transmission (BS-RS RS-MS...
In this paper, we study an opportunistic resource scheduling problem for the relay-based OFDMA cellular network where relay stations (RSs) perform coding with downlink and uplink sessions of a mobile station (MS). To end, consider time-division duplexing (TDD) each time-slot is divided into three phases according to type transmitter nodes, i.e., base (BS), MSs, RSs. Moreover, improve flexibility allocation, allow dynamic TDD, in which time duration phase can be adjusted. For coding,...
The purpose of this study was to examine the contribution leisure activities optimism and personal growth among older adults. We used data from Alameda County Health Ways Living Study. sample consisted 1600 individuals who were 60 years age older. While literature shows that participating in is relevant improving well-being adults, impact such participation across various groups yet be determined. employed a one-way multivariate analysis variance determine group differences with regard...
Abstract The purpose of this study was to develop a scale measure leisure facilitators and report its initial psychometric evidence. Moderate correlations were observed for the association motivation with facilitators. Leisure also significantly correlated constraints. t-tests investigating standardized path coefficients significant, suggesting that all paths assisting in prediction their assigned factors. These results provide supporting evidence convergent validity indicators. Model-fit...

The value of the temporomandibular joint (TMJ) projections panoramic radiography for diagnosing TMJ osteoarthritis is not completely elucidated. This study aimed to assess diagnostic accuracy and reliability detect bony lesions in patients with osteoarthritis. included 55 TMJs 44 subjects who were diagnosed They underwent (PanRad), lateral (LatTMJ) frontal (FrnTMJ) projection radiography, cone-beam computed tomography (CBCT). All images examined by two observers flattening, erosion,...
The purpose of this study was to examine the effectiveness festival attributes and tourism facilitators on tourist satisfaction. results show that has a positive significant effect tourists' Data analysis also revealed intrapersonal structural However, interpersonal do not allow impact satisfaction in context. One most important findings is commercialization strongest predictor Structural are regarded as primary importance determining tourists. Future research needed investigate other...
As the peak-end rule suggests that peak and end moments are a better predictor of overall evaluations experiences than an average total experiences, purpose this study was to examine role in predicting satisfaction with visitors' experiences. The data collected from 187 visitors who participated alleyway historical tour areas. results support for visitor associated travel tourism behavior. also distinct roles positive enjoyment, happiness, pleasure demographic variables explain satisfaction....

The spatial dose distribution across a feature, derived by conventional 2-D proximity effect correction scheme, is “V-shape,” i.e., higher closer to edges. With such distribution, it extremely difficult realize vertical sidewall in the resist profile for nanoscale features while reducing critical dimension (CD) error. In this paper, shown that, order achieve of feature with minimum total dose, shape other than V-shape must be used. This due fact that lateral development becomes comparable...
