Abstract:

An aggregate model to estimate intersection fuel consumption is developed, and the effects of signal timing on fuel consumption are investigated. A conceptual framework is proposed to identify interrelationships among traffic characteristics, signal control strategies, and roadway geometric conditions. On the basis of the framework, an Analytical Fuel Consumption Model (AFCM) is developed to estimate fuel consumption at signalized intersections. The AFCM, based on considerations of vehicle operating conditions, describes how fuel is consumed on three street segments (inbound approach, intersec

Abstract:

In this paper, Adaptive fuzzy c-means (AFCM) was used to generate an initial contour curve which overcomes leaking at the boundary during the curve propagation. Firstly, AFCM algorithm computes the fuzzy membership values for each pixel. On the basis of AFCM the edge indicator function was redefined. Using the edge indicator function the segmentation of medical images which are added with salt and pepper noise was performed to extract the regions of interest for further processing. The results of the above process of segmentation showed a considerable improvement in the evolution of the level

Abstract:

Mobile agent (MA) technology exhibits remarkable efficiency when integrated into Wireless Sensor Networks (WSNs) for information processing tasks. MAs reduce network overhead by executing processing code locally on nodes and selectively transmitting significant data to designated remote sensor nodes, thereby enhancing data fusion and acquisition while minimizing energy depletion. However, in large-scale networks, relying on a single MA leads to significant delays, necessitating the use of multiple MAs to operate asynchronously and minimize latency. The challenge lies in effectively grouping no

Abstract:

In tomato production, one of the most significant problems is the identification of Tomato Leaf Disease (TLD). Plant leaf disease is the primary factor that influences both the quality and quantity of crop production. India holds the second position in tomato making. However, multiple diseases contribute to the decline in the quality of tomatoes and the decrease in crop yield. Hence, it is important to accurately categorize and diagnose the tomato plant leaf infection. The productions of tomatoes are impacted by many leaf diseases. Early recognition of the diseases helps to reduce the disease

Of late, frequent itemset mining from the data bases has emerged as a highly challenging task.

In the erstwhile frequent itemset mining technique, the frequent itemset are extracted from the time series data by means of Adaptive Fuzzy C-Means (AFCM) clustering, though it is saddled with several setbacks in the clustering procedure. This arises on account of the fact that in clustering, the number of itemset is mammoth, and hence the method consumes a lot of time in addition to s

The aim of this study is to characterize the different farming practices observed in the Red Maradi goat farms located in the North East of Benin. Data collection took place between August and December 2019, in 90 goat farms with at least one breeding nucleus of the Red Maradi breed. Using the Multiple Correspondence Factor Analysis (AFCM) and Ascending Hierarchical Classification (CAH) methods, a typology of Red Maradi goat farms in the region was d

Dans un contexte qui réclame la maîtrise de la fécondité pour atteindre les objectifs nationaux et mondiaux du développement, la prévalence contraceptive au Burundi reste faible. De surcroît, la proportion des femmes en union sans intention de recourir à la contraception moderne a récemment augmenté. Cette proportion est passée de 53% en 2010 à 66% en 2016-2017. En se basant sur les données des Enquêtes Démographiques et de Santé du Burundi (EDSB) réalisées en 2010 et 2016-2017, cette étude a pour objectif de déterminer le profil socio-démographique des femmes sans intention de contraception m

Background: Atrial fibrillation (AF) is independently associated with the onset of cognitive decline/dementia. AF catheter ablation (AFCA) is the most effective treatment strategy in terms of sinus rhythm maintenance, but its effects on dementia prevention remain under investigation.

Abstract:

Petrophysical properties were evaluated in five wells in eastern Central Swamp Depobelt, Niger Delta using well logs. Analyses by Kingdom Suite software reveal that reservoirs’ thicknesses ranged between 24.5ft in SNG in Afam 16 to 200.5ft in SNB in Obeakpu 005. Volume of shale varies within and across all the wells with values <30% of the total thicknesses. Relative permeability to water (Krw) ranges from 0.00 to >1.00 across the wells. Reservoirs SNE and SNF in Afam 16 have average Krw of 0.00 implying 100% water-free hydrocarbon production. SNC reservoir in Afam 15 and Afam 16 has ave

It is well known that about 80% of electric fire occurs by arc fault. The arc fault can be generated in loose wire connection or damaged wire, outlets, appliances, extension cords, etc. To mitigate the electric fire, US mandated to use Arc Fault Circuit Interrupters (AFCI) since 2002. Before AFCI has been developed, Ground Fault Circuit Interrupters (GFCI) were used for prevention of electric shock accident but GFCIs are not able to detect arc fault that is main cause of electric fire. After AFCI requirement of US established, Canada, Europe, New Zealand also adopted the AFCI as mandatory. It

Abstract:

To examine the role of germinal centers (GCs) in the generation and selection of high affinity antibody-forming cells (AFCs), we have analyzed the average affinity of (4-hydroxy-3-nitrophenyl)acetyl (NP)-specific AFCs and serum antibodies both during and after the GC phase of the immune response. In addition, the genetics of NP-binding AFCs were followed to monitor the generation and selection of high affinity AFCs at the clonal level. NP-binding AFCs gradually accumulate in bone marrow (BM) after immunization and BM becomes the predominant locale of specific AFCs in the late primary response.

Abstract:

In this paper, an improved conforming AFEM (C-AFEM) for efficient modeling of arbitrary crack propagation and branching is proposed and validated. An explicit formulation for branching cracks has been derived within the C-AFEM framework. The conjugate gradient method is integrated into the C-AFEM formulation to solve the local problem that consists of all elements traversed by single or multiple cracks. Multiple numerical evidences show that this new approach can substantially improve the modeling efficiency. The solution accuracy and numerical robustness are also significantly improved.

We evaluated sex-related differences in AF and in AFCs to extend personalized medicine to prenatal life. AFCs and AF were obtained from healthy Caucasian pregnant women who underwent amniocentesis at the 16th–18th week of gestation for advanced maternal age.

Fluorescent labelling of monoclonal antibodies (mAbs) is classically performed by chemical bioconjugation methods. The most frequent labelling technique to generate antibody–fluorophore conjugates (AFCs) involves the bioconjugation onto the mAb lysines of a dye bearing an N-hydroxysuccinimide ester or an isothiocyanate group. However, discrepancies between labelling experiments or kits can be observed, related to reproducibility issues, alteration of antigen binding, or mAb properties.

Abstract:

River silt deposited by water in coastal areas is unsuitable for engineering construction. Thus, the in situ stabilization treatment of river silt as the bearing layer has been an important research area in geotechnical engineering. The strength degradation behavior and mechanism of stabilized river silt reinforced with cement and alginate fibers (AFCS) in different engineering environments are crucial for engineering applications. Therefore, freeze–thaw (F–T) cycle tests, wetting-drying (W–D) cycle tests, water immersion tests and seawater erosion tests were conducted to explore the strength
