ABSTRACT

Increasing the private vehicles namely own car, taxi, microbuses and coaches as

a mode of transport is due to its inherent advantages associated with its usage. In

Tripoli due to rapid increase in private vehicles usage associated with no public

transport system namely public buses and train has resulted in increase of traffic

congestion problem, accidents and inadequate of parking spaces. The objective of

this study which identify the factors encourage users of own car and private

vehicles to shifting to public transport system. Re-establish of public transport

system and decreasing own car users simultaneously has become necessary for

solving traffic congestion problems and reduces road accidents and travel time

for all trips. A questionnaire survey was carried out on users of private vehicles

transport in the Tripoli such as car owners, passengers, taxis and microbuses

drivers (n = 900). The probability of car drivers shifting to public transport was

examined based on scenario several options such as reduction and improve in

public transport travel time. Improve travel time by70% will be encourage

switching about 82.3% to switch from use own car to use public transport system

services. Logistic regression technique has been used to analyses the factor that

impact users to switch their trips to public transportation system alternatives.

Statistical Package for Social Science (SPSS) version 19 and Excel 2007

software were used to analysis the questionnaire in this study.

Abstract: Currently, Tripoli the capital city of Libya experiences a steady increase in traffic

volumes on its road network especially in the city centre. The increase has caused traffic

problems. Tripoli has registered an increase private cars ownership approaching 743,796

vehicles of the total registered vehicles in the city, which reach more than one million at the

end of 2009. A study has been carried out in Tripoli city authority areas among own car users

who live in the areas with lack of private transport and no public transport (PT) services. A

questionnaire survey in Tripoli area was carried out to study the potential reduction of private

cars on road through optimal use of suitable public transportation system in order to reduce

traffic problems and travel time. Logistic regression model has been used to analyse the factor

that impacts users to switch their trips to public transportation alternatives.

We are concerned here with the existence of at least one positive

continuous solution of the quadratic integral equation of fractional orders

x(t) = a(t) + Iαf(t; x(t)) · Iβg(t; x(t)); α; β 2 (0; 1]:

The maximal and minimal solutions are also proved. Some applications are

given.

Abstract:

Interpersonal behavior depends mainly on cultural concepts in which

values, beliefs and norms certainly regulate actions, reactions and behavior

so, in a way, the interactions of the individuals in societies are always

under the influence of the cultural standards of the society. Consequently

the men and women in a society focus their attention on satisfying their

personal and social needs related to their behavior in which self-

consciousness and social emotions are kept in a balanced system without

being violated by the cultural norms.

Surprise, anger, disgust, fear and happiness are self conscious inherited

emotions where it can be noticeable through body language and in all

psychological development categories; on the other hand, the complicated

self emotions such as shame and stigma correlate with fear of negative

evaluation and differ from culture to another.

AYEB concept one of the main Arab cultural concepts related to both

inherited and complicated emotions and the concept lack conceptualization

and empirical studies.

Abstract: Increasing dominance of private car as a mode of transport is due to its inherent advantages

associated with its usage. In Tripoli, Libya due to rapid increase in car usage associated with poor

public transport system, has resulted in increase of traffic congestion, road accidents and street parking

spaces. This study aims to identify the factors encourage users of own car to switching to public

transport. Introducing the public transport (PT) system and reduce own car users simultaneously has

become necessary for solving congestion problems and reduces road accidents and improve travel time

for all trips. A questionnaire survey was carried out on users of transport in the city such as car

owners, passengers, taxis and micro buses drivers (n = 600). The probability of car drivers switching

to public transport was examined based on scenario several options such as reduce and improve in

public transport travel time. Logistic regression technique has been used to analyses the factor that

impact users to switch their trips to public transportation alternatives. Statistical Package for Social

Science (SPSS) and Excel 2007 software were used to analysis the questionnaire in this study.

Abstract— Transport modes are very important to Libyan’s Tripoli residents for their daily trips. However, the total number of own car and private transport namely taxi and micro buses on the road increases and causes many problems such as traffic congestion, accidents, air and noise pollution. These problems then causes other related phenomena to the travel activities such as delay in trips, stress and frustration to motorists which may affect their productivity and efficiency to both workers and students. Delay may also increase travel cost as well inefficiency in trips making if compare to other public transport users in some Arabs cities. Switching to public transport (PT) modes alternatives such as buses, light rail transit and underground train could improve travel time and travel costs. A transport study has been carried out at Tripoli City Authority areas among own car users who live in areas with inadequate of private transport and poor public transportation services. Analyses about relation between factors such as travel time, travel cost, trip purpose and parking cost have been made to answer research questions. Logistic regression technique has been used to analyse these factors that influence users to switch their trips mode to public transport alternatives.

Digital video steganography has attracted a great deal of research interest in the recent few years in applications. In this paper, we propose a method to embed and encrypt messages into video sequences by using steganography technique Based on the H.264 video coding standard. The system implemented in this work provides robust H.264 video compression constant, without significantly affecting the overall bit rate and quality of the video stream. The results indicate that the algorithm can be implemented steganography fast and efficiently and effect vision and peak signal to noise ratio (PSNR) of video sequences are almost unaffected after decoding.
