Telecommunication customer satisfaction using self‐organized network‐based heuristic algorithm

The emerging network including long‐term evolution‐advanced (LTE‐A) aims at enhancing the telecommunication customer satisfaction in numerous aspects including system capacity, network coverage, handover management, and quality of service (QoS). Effective handover (HO) management reduces HO failure and hence enhances the data rate and supports user mobility. There are numerous challenges that increase the call drop rate. Among the main challenges that increase the call drop rate, the variable user speeds and variable traffic loads are the major ones. Hence, the time to trigger (TTT), HO margin (HOM), and HO offset (HOO) are used to evaluate the HO management using self‐organized network‐based heuristic algorithm under variable user speeds and variable traffic loads. In recent researches, different HO management techniques were applied to manage the HO decision including fuzzy‐logic tactics and Q‐learning. However, they did not apply intelligent optimization techniques that adapt the variable user speeds and dynamic traffic loads. This paper aims at increasing the telecom customer satisfaction by decreasing the call drop rate using particle swarm optimization (PSO), which adaptively manages the handover control parameters according to the user speed and traffic loads. The simulation results have shown that the proposed optimization tool results in significant call drop rate reduction compared to the ordinary HO management.
Variation of 2-Acetyl-1-Pyrroline Concentration in Aromatic Rice Grains Collected in the Same Region in Japan and Factors Affecting Its Concentration

Abstract Aroma strength of aromatic rice varies with the genetic and environmental conditions. We determined the concentration of 2-acetyl-1-pyrroline (2AP), a key compound of the aroma of aromatic rice, in 62 samples of rice grains (brown rice) from‘Hieri’ produced by 17˜24 farmers in 3 years in the Kubokawa area of Kochi Prefecture, Japan. Many ofthem showed similar values and the standard deviations were 27˜31%. However, a few samples showed extremely high (200%) or low (60%) 2AP concentrations compared to the individual year averages (100%). The influence of harvest time and temperature during ripening on the 2AP concentration in the brown rice was also examined using two cultivars. During grain development in an early-heading cultivar ‘Miyakaori’ , the 2AP concentration in the brown rice reached a peakat 4 or 5 weeks after heading (WAH) and then decreased rapidly to 20% of the maximum at 7 or 8 WAH. In a late-heading cultivar ‘Hieri’, the 2AP concentration peaked at 4 WAH then gradually decreased to 40% of the maximum at 8 WAH.The 2AP concentration was higher in brown rice ripened at a low temperature (day : 25°C/night : 20°C) than that ripened at a high temperature (day: 35°C/night: 30°C) in both a short-grain cultivar ‘Hieri’ and a long-grain cultivar ‘Sari Queen’.
On the Slavic Immigration in the Byzantine Balkans

The Balkans have a complex ethnic and linguistic structure owing to migrations from the North which took place in waves of varying intensity and changed the regions demographic character from the antiquity onwards, when it was inhabitated by Illyrian and Greek tribes.1 The Slavic immigration from the late 6th century onwards was the most important for the present ethnic composition of the populations in southeastern Europe. It has been a matter of great debate since Jacob Philipp Fallmerayer (1790–1861) published his notorious thesis, stating that “not the slightest drop of undiluted Hellenic blood flows in the veins of the Christian population of present-day Greece”. 2 Already since the 12th century Byzantine historians like Nikephoros Bryennios (12th century), George Pachymeres (13th century), Nikephoros Gregoras (14th century), Michael Kritoboulos and especially Laonikos Chalkokondyles (15th century) discussed the ethnic identities of the medieval Balkan populations and their alledged Illyrian origin. They used the ethnonyms Albanoi, Akarnanoi, Bosnoi, Bulgaroi, Dalmatai, Illyrioi, Makedones, Mysoi, Sarmatai, Skythai, Thrakes, Thessaloi and Triballoi.3 The collective names of the Slavs,
Hybrid drone powered by combined gasoline and electric motors

This work investigates design of a drone for transporting valuable objects. All the required components for building the drone and discussed. The drone can carry a maximum payload of 10 kg for a long duration over reasonable distance. This is achieved by using a hybrid mechanism that combines two 25cc fuel engines with four electrical motors operating by two 6S lithium polymer (LiPo) batteries. The hybrid mechanism is chosen as it tackles the electric drone main problems which are: short flight duration and low payload-carrying ability.
Comparative Pattern of Emergence of Heliothis zea and H. virescens (Lepidoptera: Noctuidae) from Overwintering Pupae

Mean Julian day for emergence from overwintering of tobacco budworms (TBW), Heliothis virescens (F.), was ca. 9 days earlier than that for bollworms (BW), H. zea (Boddie), in a plot of pigeon peas, Cajanus cajan L. , in central Texas in 1980–1981. Females of both species emerged 4 or 5 days earlier than males. In areas where pigeon pea stalks were left in the field at the end of the growing season, a significant delay of 4 days occurred in the subsequent spring emergence of TBW when compared to areas where stalks were removed at the end of the growing season. This effect was less obvious with BW. Numbers of moths of either species that emerged from plots from which birds were excluded were not significantly different from those emerging from plots from which birds were not excluded; however, bird foraging activity in the plots during the overwintering period was low and the bird netting used was not effective in excluding birds. Synchrony between the spring emergence of male TBW and their capture in pheromone traps demonstrated the feasibility of using pheromone traps to monitor overwintering emergence. On the other hand, asynchrony between the capture and emergence of BW males indicated that movement of the species into the area may occur before emergence from overwintering.
Melt-rock interaction in the subarc mantle: records from the plagioclase peridotites of the southern Palawan Ophiolite, Philippines

ABSTRACT The interaction between migrating melts and the upper mantle largely affects the composition of the ascending melt and residual peridotites. In island arcs, melt-rock interactions and products which involved highly depleted mantle peridotites are still largely undocumented despite their petrological importance. In this contribution, the petrographic and geochemical signatures of refractory and refertilized peridotites comprising the mantle section of the southern Palawan Ophiolite, Philippines are investigated. The peridotites are dominantly comprised of residual spinel harzburgites with minor dunite and plagioclase peridotites. Spinel harzburgites are similar to other highly depleted residual mantle materials of other suprasubduction zone ophiolites. Plagioclase peridotites, which are cut by gabbroic intrusions, preserve distinct petrological characteristics indicating melt-rock interaction. The melts preserved as gabbroic dikes have signatures transitional between mid-ocean ridge and island arc, and are comparable to back-arc basin lavas. We therefore propose that the plagioclase peridotites were formed due to the reaction between highly depleted mantle peridotites beneath an intraoceanic arc and migrating BABB-like magmas possibly during the incipient stages of back-arc rifting.
Equatorial Deep Jets and Their Influence on the Mean Equatorial Circulation in an Idealized Ocean Model Forced by Intraseasonal Momentum Flux Convergence

Equatorial deep jets (EDJ) are vertically stacked, downward propagating zonal currents that alternate in direction with depth. In the tropical Atlantic, they have been shown to influence both surface conditions and tracer variability. Despite their importance, the EDJ are absent in most ocean models. Here we show that EDJ can be generated in an idealized ocean model when the model is driven only by the convergence of the meridional flux of intraseasonal zonal momentum diagnosed from a companion model run driven by steady wind forcing, corroborating the recent theory that intraseasonal momentum flux convergence maintains the EDJ. Additionally, the EDJ in our model nonlinearly generate mean zonal currents at intermediate depths that show similarities in structure to the observed circulation in the deep equatorial Atlantic, indicating their importance for simulating the tropical ocean mean state.
Ecocardiografia modo M em cães normais da raça Pastor Alemão (origem americana) do canil da polícia militar do estado de Minas Gerais, Brasil

The normal M-mode echocardiographic parameters were determined in German Shepherd dogs from Minas Gerais State Police kennel. Sixty clinically normal dogs were submitted to the echocardiographic examination. The right ventricular internal dimension at end-diastole, the left ventricular internal dimension at end-diastole and end-systole, the left ventricular mass, the aortic root dimension, left atrial systolic dimension, end-diastolic interventricular septal thickness and end-diastolic and end-systolic left ventricular posterior wall thickness had significant correlation with body weight. The ratio of septal to left ventricular posterior wall thickness at end-distole, the left atrial to aortic root ratio, the thickening fraction of the interventricular septum, the thickening fraction of the left ventricular posterior wall, and left ventricular shortening fraction showed no linear correlations with body weight, sex or age.
Effect of sintering parameters on the microstructure and compressive mechanical properties of porous Fe scaffold fabricated using 3D printing and pressure less microwave sintering

The demand for the porous scaffold has been increasing globally in the biomedical field due to numerous advantages over dense structures like high damping capacity, high specific strength, and improved cell integration growth. In the present study, porous iron scaffolds were fabricated using micro-extrusion-based three-dimensional printing and pressureless microwave sintering. For the preparation of samples, metal-based polymeric ink was developed. Thereafter, cylindrical samples were printed and then sintered in a microwave sintering furnace. The experimental investigations were performed to estimate the effect of sintering parameters such as sintering temperature, heating rate and soaking time on the compressive and microstructural property of the fabricated samples. Microstructural characterization was done using the electron backscatter diffraction technique. The experimental observations deduced that the compressive yield strength and apparent density of the sintered sample increased with the increase in sintering temperature and decreased with a further rise in temperature. Moreover, the electron backscatter diffraction analysis unveiled that the high heating rate resulted in the reduction of compressive yield strength due to rapid grain growth. Additionally, the significant effect of soaking time on the compressive mechanical properties was also noticed due to the increase in the grain size diameter. From the X-ray diffraction plot, it was found that there was no contamination present in the fabricated scaffold. In order to evaluate the process capability, a case study was performed wherein the topologically ordered porous structure of iron was fabricated at optimum sintering parameters.
Temperature‐dependent development of diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae) on two brassicaceous host plants

The effect of temperature on the development of the Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae), was evaluated at eight constant temperatures (10, 15, 20, 25, 28, 30, 32.5 and 35°C), with relative humidity of 65% and a photoperiod of 14:10 (L:D) hours on two host plants, cauliflower, Brassica oleracea var. botrytis and cabbage, Brassica oleracea var. capitata. The low temperature threshold was estimated to be 7.06°C and 7.84°C and the thermal constant was 263.74 and 261.58 degree‐days for P. xylostella on cauliflower and cabbage, respectively, using the linear model. Data were fitted to various nonlinear temperature‐dependent models, and the low and high temperature thresholds, as well as the optimum temperature for development, has been estimated. Criteria of choice from the literature were used to evaluate models and to select the most suitable equation for P. xylostella development on each host plant. Conclusively, linear and Briere‐2 models are recommended for the description of temperature‐dependent development of P. xylostella on two host plants.
Scaling-up Field Testing of Modified MicroorganismsProblems with applying small-scale field data to large-scale tests of genetically engineered microorganisms

through small-scale field tests (defined by the US Environmental Protection Agency [EPA] as less than ten acres). EPA regulations on small-scale release of genetically engineered microorganisms into the environment are clearly defined (Federal Register 1986a), but regulations for largescale releases (none of which have yet been undertaken) are vague (Federal Register 1986b). For example, even the maximal size for such releases has not been set.
Variation in antioxidant components of tomato during vine and post-harvest ripening

The variation in the antioxidant content (lycopene, β-carotene, ascorbic acid and total phenolics) was evaluated on two tomato genotypes during vine and post-harvest ripening. Tomatoes were sampled and analysed at seven ripening stages according to the colour value. The data indicate that ripening conditions affected both the antioxidant accumulation kinetics and the final content, which was higher in post-harvest-ripened fruits. In particular, lycopene mainly accumulated in the very last period of ripening and its content was not linearly related to colour changes. Antioxidant accumulation and other ripening indexes were not significantly different in the two tomato genotypes. © 1999 Society of Chemical Industry
AQT—A Query Template for AutomationML

This article proposes the AutomationML query template (AQT) for accessing engineering data stored in the XML-based data format AutomationML (IEC 62714). The motivation of AQT is to facilitate query construction for domain experts who are familiar with AutomationML but unskilled in programming. The contribution of the article is threefold. First, AQT has an AutomationML-based syntax, which allows constructing queries using conventional AutomationML tools, e.g., the AutomationML Editor. Second, the formal semantics of AQT is defined based on the notion of tree pattern queries, which are a fundamental concept for querying tree-structured data, including XML. Finally, algorithms are presented for the automated translation from AQTs to XPath and XQuery programs, which can be executed on any standard-conform XQuery processors. We show that AQT covers the essential query requirements for AutomationML and provide a prototype implementation in Java.
Cord lipid profile comparison of newborns of hypertensive mothers

Given the understanding that fetal lipid profile will show deranged results either due to genetic programming or due to prepartum and/or intrapartum stress, and that this deranged lipid profile can continue into adult life, it is wise to recognize such children at risk in the antenatal and postnatal period itself and give special attention to them in terms of life style modification to prevent development of future complications; particularly cardiovascular complications.
Effect of Isocarbon-4 and Isocarbon-5 Volatile Fatty Acids on Microbial Protein Synthesis and Dry Matter Digestibility In Vitro

Abstract We evaluated the effect of a mixture of ammonium salts of isocarbon-4 (31.5%) and isocarbon-5 on microbial nitrogen incorporation and in vitro dry matter digestibility of addition acids (68.5%) on a dry matter basis to batch-culture fermentation systems receiving corn silagebased diets, Isocarbon-4 and isocarbon-5 salts at 1% of dry matter in the diet of 13 to 16% crude protein supplemented with cottonseed or corn gluten meal and urea incubated for 18, 24, or 48h increased microbial nitrogen incorporation and dry matter digestion at 24-h incubation time. Addition of isocarbon-4 and isocarbon-5 salts at . 5, . 75, 1.0, and 1.25% of dry matter increased microbial nitrogen incorporation with the corn gluten meal diet and increased dry matter digestion with the corn gluten and cottonseed meal diets, Isocarbon-4 and isocarbon-5 salts at 1% of dry matter in 16% crude protein cottonseed meal, corn gluten meal and urea, soybean meal, or alfalfa haylage and soybean meal diets increased microbial nitrogen incorporation for the alfalfa haylage and corn gluten meal diets. Interaction of crude protein and treatment was not consistent. Addition of isocarbon-4 and isocarbon-5 salts increased dry matter digestion and microbial growth in vitro.

Environmental Control on Transpiration: A Case Study of a Desert Ecosystem in Northwest China

Arid and semi-arid ecosystems represent a crucial but poorly understood component of the global water cycle. Taking a desert ecosystem as a case study, we measured sap flow in three dominant shrub species and concurrent environmental variables over two mean growing seasons. Commercially available gauges (Flow32 meters) based on the constant power stem heat balance (SHB) method were used. Stem-level sap flow rates were scaled up to stand level to estimate stand transpiration using the species-specific frequency distribution of stem diameter. We found that variations in stand transpiration were closely related to changes in solar radiation (Rs), air temperature (T), and vapor pressure deficit (VPD) at the hourly scale. Three factors together explained 84% and 77% variations in hourly stand transpiration in 2014 and 2015, respectively, with Rs being the primary driving force. We observed a threshold control of VPD (~2 kPa) on stand transpiration in two-year study periods, suggesting a strong stomatal regulation of transpiration under high evaporative demand conditions. Clockwise hysteresis loops between diurnal transpiration and T and VPD were observed and exhibited seasonal variations. Both the time lags and refill and release of stem water storage from nocturnal sap flow were possible causes for the hysteresis. These findings improve the understanding of environmental control on water flux of the arid and semi-arid ecosystems and have important implications for diurnal hydrology modelling.
THE LIFE CYCLE OF THE MARINE AMPHIPOD STEGOCEPHALUS INFLATUS KRØYER IN THE NORTHWEST ATLANTIC

Collections from the arctic and the Gulf of St. Lawrence were analyzed in order to study the life cycle. Evidence is presented to show that Stegocephalus inflatus is protandrous, produces broods throughout the year, and that each female has more than one brood. The relationship between length and brood size is calculated to be N =. 000036 L4.03.
Competitive Networks: Nontransitive Competitive Relationships in Cryptic Coral Reef Environments

Nonhierarchial sequences of interference competitive abilities, competitive networks, have been observed in Jamaican cryptic coral reef environments and also appear to exist in Jamaican open reef surface environments. These competitive networks are both numerous and complex; they appear more likely to be formed by interactions between than within major taxonomic groups. The exact spatial position an organism occupies and the rate at which organisms overgrow one another will be important determinants of patterns of species distribution on substrata supporting competitive networks. This will not be the case if a competitive hierarchy exists. The existence of a competitive network on a particular substratum will serve to increase the length of time required for single species resource monopolization relative to the time which would be required if a competitive hierarchy exists, assuming equivalent rates of overgrowth in both cases. The competitive networks situation provides a mechanism for the development of specific types of coevolutionary relationships.
Resource partitioning within a browsing guild in a key habitat, the Chobe Riverfront, Botswana

Resource partitioning between elephant, giraffe, kudu and impala was assessed. This was to address concerns that elephant population increase adversely affects other species through depleting their food in key areas close to permanent water. Resources considered were woody species browsed, height browsed and plant parts browsed. Animals were observed as they browsed and the plant species, browsing heights and plant parts browsed were recorded. Observations were made over 1 y and the data were divided between wet and dry season. Schoener's index of resource use overlap was calculated for plant species, browsing heights and plant parts eaten and differences in overlap between wet and dry season were tested. Levin's measure of niche breadth in plant species utilized by the different browsers was calculated. Woody species identity was the main separator between food resources that elephant used and those giraffe, impala and kudu used. Giraffe, kudu and impala mainly browsed the same species and plant parts but browsed at different heights. There was no difference in resource use overlap between seasons with different resource availability. Since elephant browsed different woody species from those browsed by the others, it is unlikely that the increasing elephant population will deplete food resources for the other browsers.
XPS guide: Charge neutralization and binding energy referencing for insulating samples

This guide deals with methods to control surface charging during XPS analysis of insulating samples and approaches to extracting useful binding energy information. The guide summarizes the causes of surface charging, how to recognize when it occurs, approaches to minimize charge buildup, and methods used to adjust or correct XPS photoelectron binding energies when charge control systems are used. There are multiple ways to control surface charge buildup during XPS measurements, and examples of systems on advanced XPS instruments are described. There is no single, simple, and foolproof way to extract binding energies on insulating material, but advantages and limitations of several approaches are described. Because of the variety of approaches and limitations of each, it is critical for researchers to accurately describe the procedures that have been applied in research reports and publications.
