Client-server-based LBS architecture: A novel positioning module for improved positioning performance

Permission to distribute obtained from publisher.This work presents a new efficient positioning module that operates over client-server LBS architectures. The aim of the proposed module is to fulfil the position information requirements for LBS pedestrian applications by ensuring the availability of reliable, highly accurate and precise position solutions based on GPS single frequency (L1) positioning service. The positioning module operates at both LBS architecture sides; the client (mobile device), and the server (positioning server). At the server side, the positioning module is responsible for correcting user’s location information based on WADGPS corrections. In addition, at the mobile side, the positioning module is continually in charge for monitoring the integrity and available of the position solutions as well as managing the communication with the server. The integrity monitoring was based on EGNOS integrity methods. A prototype of the proposed module was developed and used in experimental trials to evaluate the efficiency of the module in terms of the achieved positioning performance. The positioning module was capable of achieving a horizontal accuracy of less than 2 meters with a 95% confidence level with integrity improvement of more than 30% from existing GPS/EGNOS services

An Approach to Conserve Gaza Architectural Heritage Through Digital Technology

Heritage is considered as one of the constituents that preserve culture and national identity of any community. This is because heritage is a witness of accumulating experiences of that community. During recent years, architectural styles have changed dramatically in our country. Modern and western styles of housing prevailed so much that the Palestinian heritage touches nearly disappeared. In addition, many of the historic buildings in Gaza City have been destroyed due to the lack of public awareness about the importance of this heritage. This situation created the need for restoring the inveterate Palestinian culture and heritage through 3D Visualizing of Architectural Heritage. Awareness of cultural heritage through publicizing the digitized simulation of this heritage by using virtual reality and 3D modelling and animation techni-ques would help in preserving it and achieving balanced environment which reflects both originality of past and modernity of contemporaneity

First record of Aequorea globosa Eschscholtz, 1829 (Cnidaria: Hydrozoa) in the coast of Syria

The Indo-Pacific jellyfish Aequorea globosa Eschscholtz, 1829 was reported last year for the first time in the Mediterranean Sea from Iskenderun Bay (S. Turkey). This jellyfish was observed in the coast of Syria, on 8 January 2012, during a regular monthly sampling program

THE ACOUSTIC AND PERCEPTUAL CORRELATES OF EMPHASIS IN URBAN JORDANIAN ARABIC

Abstract Acoustic and perceptual correlates of emphasis, a secondary articulation in the posterior vocal tract, in Urban Jordanian Arabic were studied. CVC monosyllables and CV.CVC bisyllables with emphatic and plain target consonants in word-initial, word-medial and word-final positions were examined. Spectral measurements on the target vowels at vowel onset, midpoint and offset revealed a significant increase in F1 and F3 and a decrease in F2 in emphatic compared to plain environments. Emphasis was observed more in the environment of high and low front vowels than high back vowels, anticipatory emphasis spread was more salient than perseveratory emphasis spread, and males showed more emphasis than females. Spectral moment measures of the target consonants themselves revealed inconsistent or no effects of emphasis. Results from a perception experiment with cross-spliced monosyllables showed that perception of emphasis follows the vowel, not the consonant, in the emphatic syllable, thus confirming the results of the acoustic experiments

Heart ventricular histology and microvasculature together with aortic histology and elastic lamellar structure: A comparison of a novel dual-purpose to a broiler chicken line

The use of dual-purpose chickens is a strategy to avoid killing one-day-old male chicks of egg laying lines. Lohmann Dual (LD) is a novel dual-purpose chicken line created by the crossbreeding of layer and broiler lines. However, many of the cardiovascular diseases of broilers are likely to be associated with intensive genetic selection for growth and feed conversion efficiency. This study aimed to compare the macroscopic and microscopic structure of the heart and the aorta of the LD chicken line with that of the broiler chicken line, Ross 308 (Ross) under typical husbandry conditions for meat production. Eighty, one-day-old male chicks of each line were housed for 5 weeks (Ross) and 9 weeks (LD). Six birds of each line were sampled weekly. Heart mass, thickness of ventricular walls, cardiomyocyte size and blood capillary density as well as aortic diameter and thickness, number of elastic lamellae and elastic fiber percentage in the aortic wall were determined. The growth patterns of the heart were the same in the two lines. Although LD chickens had a lower absolute heart mass than that of Ross chickens, the relative heart mass in both lines was similar. The cardiomyocytes of LD chickens were larger than those of Ross’s of the same body weight (BW), nevertheless both lines had similar thicknesses of their ventricular walls. The blood capillary density was greater in the LD heart than in that of the Ross heart. The aorta of LD chickens had proportionally; a greater aortic lumen radius, larger numbers of elastic lamellae and more elastic fibers than in Ross chickens. Our results suggest that the heart and aorta of the LD chickens have not been disadvantaged by their intensive genetic selection; furthermore, LD chickens have a better myocardial capillary supply and better aortic mechanical properties than those of Ross chickens

Computed tomography study of the fetal development of the dairy cow stomach complex

In the fetal development of animals, critical physiological and anatomical events influence the long-term health and performance of the offspring. To identify the critical growth phases of the fetal bovine stomach, we used computed tomography imaging on 30 German Holstein fetuses to examine the fetal bovine stomach in situ. Computed tomography allows the study of diverse parameters such as the volume of the stomach chambers in situ without the need for sophisticated filling preparation techniques. The absolute volume, relative volume, and monthly volume increase of each stomach chamber were determined. Computed tomography was a reliable method for in situ examination of the fetal bovine stomach complex from the third month of gestation onward. It was able to detect an abnormal position of the abomasum in 2 fetuses. The crown-rump length of the fetuses studied ranged from 9.5 to 89 cm (from 2.2 to 8.3 mo of gestation). Over this timeline, the changes in the relative volumes of the ruminoreticulum and abomasum were inversely related. Until mo 5 of gestation, the relative volume of the ruminoreticulum increased steadily, whereas that of the abomasum decreased. Thereafter, the relative volume of the ruminoreticulum became gradually smaller, and that of the abomasum became larger; by mo 8, the abomasum was larger than the ruminoreticulum. All stomach chambers had large increases in volume over the gestation period and we observed differences in development patterns and volume changes of the individual stomach chambers over this period. The largest monthly volume increase of the stomach complex was between mo 4 and 5 of gestation. In this period, the volume of the ruminoreticulum increased 43.8 times, that of the omasum 38.9 times, and that of the abomasum 30.03 times. Between mo 5 and 6 of gestation, the abomasum had another growth spurt, with a monthly volume increase of 10.4 times. These 2 time points in the gestation period may be critical phases of fetal development that should be considered in the management of pregnant cattle

Structure and age-dependent growth of the chicken liver together with liver fat quantification: A comparison between a dual-purpose and a broiler chicken line

Rearing dual-purpose chickens is a practicable approach to avoid culling one-day-old male layer chicks. The present study examined the impact of a conventional fattening diet on the liver of a novel dual-purpose chicken line (Lohmann Dual, LD) in comparison to a broiler (Ross 308) chicken line. Age-related changes of structure and lipid content of the liver were assessed. One hundred twenty and newly hatched chicks (LD = 66, Ross = 54) were kept under the same husbandry conditions and fed a commercial diet for 5 weeks for Ross and 9 weeks for LD. Six birds of each line were examined weekly. Their body weight (BW) and liver mass were recorded. Microscopic structure and ultrastructure of the liver were investigated and the liver lipid content was measured using a pre-validated method. During the study period, liver mass increased with age, while normalized liver mass decreased. Furthermore, liver mass of Ross birds was greater than that of LD birds of the same BW. Overall, no significant differences were observed in the hepatic structure or ultrastructure between the two chicken lines. The hepatic lymphatic aggregations were without fibrous capsules and their number and area increased throughout the first week, then the values began to fluctuate with age in both chicken lines. The changes in the liver lipid content of the two chicken lines were within the normal physiological range over the term of the study. The liver lipid content correlated negatively with age and body weight in both lines. It was the highest on the first day then decreased until day 7 and thereafter did not change in both chicken lines. However, given the same body weight, the Ross chickens had a 9% greater liver lipid content than LD chickens. It is concluded that there is no apparent adverse effect of a high-energy diet on the liver of LD chickens

The social and economic impacts of e-hailing application in Malaysia: A review

E-hailing is a service that allows users to book a journey online and provides a platform for users to interact with E-hailing companies. E-hailing service in Malaysia was launched in January 2018. Growing population and rising migration from rural to urban areas have put a strain on quality of life for Malaysia's population. The service is available in Malaysia. It has so far had success. E-hailing services have become more popular than traditional taxis for a variety of reasons. Customers are likely to seek out these providers' services as long as they pay close attention to their needs, solicit feedback often, and improve the quality of the services they give. Mobile applications developed by e-hailing businesses have had a significant influence on the taxi industry and public transportation in the last few years. Experts examined the impact of e-Hailing services on consumers, drivers and the public economy. Economics service created a lot of work prospects for drivers. Taxi industry struggling to keep up with E-Hailing system which put it under threat, as it cuts in taxi industry's profits. All e-hailing drivers must now obtain Public Service Vehicle (PSV) permits, but they complained that the regulations were too strict. Many of these driver-partners used E-hailing as a method to earn supplemental money in addition to driving. In the next several years, the way people move around in cities is anticipated to alter drastically. The conventional marketplace is being replaced by the online transaction as a method of conducting business. E-hailing in Malaysia today, as an alternative to private and public transportation, may be summed up by pointing out its increasing use
