The Moment

The construction of railway line between Rantau Prapat and Kotapinang is expected to ease transportation process from Medan to Kotapinang, which could improve economic activities and become the alternative solution to make a trip. At the moment, existing public transport that covers this route is strictly limited to only medium or big buses. This research aims to identify the characteristic of trip maker and also to analyze the probability of mode shifting from bus to train for the mentioned trip. We use stated preference survey questionnaire, and it was distributed to random minimul sample needed. In order to obtain the utility function of the trip maker, the obtained data was then modeled in binomial logit method using SPSS statistical software. Tthe analyzed attributes difference (Δ) are trip cost difference (ΔX1), waiting time difference (ΔX2), travel time difference (ΔX3). The generated model has 0.114 of R2, and the probability of shifting from bus to train is 31.93% if the trip cost difference was Rp. 30.000. Meanwhile, the probability of shifting is 50.15% if the waiting time difference was less then 30 minutes. Lastly, the probability of shifting is 57.96% if the travel time difference was 1 hour.

Cheboksary reservoir impact to the coast is manifested in the geophysical impact associated with abrasion activities. Geomorphological area of influence at the moment reaches a width of about 40 m, where are the coasts reformation (erosion, collapse, slumping, sliding, transfer or accumulation of sediments, waterlogged processes). Hydrogeological impact is effect on the level of groundwater. We have proposed the conceptual foundations of functional zoning of the reservoir banks that will help to optimize its operation. Selection zones came in accordance with the principles of landscape planning: 1. The zone of strict water protection: the main purpose – preservation of needing special protection areas. 2. The zone of moderate restrictions: preservation extensively used landscapes. 3. The zone of partial restrictions: improving the pre-emptive particularly vulnerable areas and changing intensity or type of use. 4. The zone of conservation of natural components in agricultural landscapes: ensuring health of the natural environment in the habitats used in agricultural economy. 5. The zone of preservation of vacant space and the natural environment in the settlements: to maintain the required quantity and quality of available green space in the large towns. 6. The zone of improving heavily used areas: elimination of harmful stress and environmental sanitation in the countryside where economic activities and the lack of measures to reduce their risks lead to degradation natural system.

When the French government introduced military conscription into the A.O.F. in 1912, the Guinean colonial authorities saw the measure as a means of training a local administrative corps to replace the traditional chieftaincy, through whose military defeat the conquest of Guinea had very largely been effected. However, the chiefs had by no means disappeared by 1914, and wartime demands for recruits were too massive to be supplied without their assistance. Their help was bought with promises to consolidate their authority in peacetime. Although able to marshal recruits, the chiefs seem to have been unable to prevent large-scale desertions before the moment of embarkation for France; village populations could also avoid conscription by overland migration out of the A.O.F. The colonial authorities therefore felt constrained to offer substantial inducements, mainly concerning improved social status vis-à-vis the chiefs, to the individual recruits. These contradictory policies were compounded by the recruitment drive of Blaise Diagne in 1918, which involved a further promise to recruits of improved status vis-à-vis the French authorities. The return of ancien combattants to Guinea was marked by outbreaks of strike action among workers in Conakry and along the railway line; by riots in demobilization camps; and by rejection of or agitation against chiefly power in the home cantons to which they dispersed. The anciens combattants did not form a coherent or organized political movement, but remained a conspicuous social grouping between the wars. Although they appear to have been strongly influenced by their experience of war and by contact with French socialists, their conflict with the chiefs seems to have counted for more with them than any confrontation with the French.

Urban Rail Transit Network

This paper proposes a novel model to optimize the first train timetables for urban rail transit networks, with the goal of maximizing passengers’ transfer waiting time satisfaction. To build up the relationship of transfer waiting time and passenger satisfaction, a reference-based piecewise function is formulated with the consideration of passengers’ expectations, tolerances and dissatisfaction on “just miss”. In order to determine the parameters of zero waiting satisfaction rating, the most comfortable waiting time, and the maximum tolerable waiting time in time satisfaction function, a stated preference survey is conducted in rail transit transfer stations in Shanghai. An artificial bee colony algorithm is developed to solve the timetabling model. Through a real-world case study on Shanghai’s urban rail transit network and comparison with the results of minimizing the total transfer time, we demonstrate that our approach performs better in decreasing extremely long wait and “just miss” events and increasing the number of passengers with a relatively comfortable waiting time in [31s, 5min). Finally, four practical suggestions are proposed for urban rail transit network operations.

This paper focuses on the current environmental issues, more specifically the amount of greenhouse gases humanity is being confronted with at the moment. The research was carried out on a niche of the topic, namely on the carbon footprint of public buildings. The concept of a sustainable university is new and insufficiently explored, and as part of the environmental metabolism, it influences anthropic sustainability in a directly proportional manner. This indicator’s monitoring systems reveal how vulnerable humanity is in front of the latency of an unprecedented and inevitable environmental catastrophe. The ecological effects may be mitigated by the academic community through green urban design. The ecological performance can be expressed in an economically efficient manner, which can, at the same time, create a precious channel of communication within the entire academic community though volunteering for sustainability. Moreover, this research has identified several solutions for optimizing the carbon footprint, which do not hinder the necessary economic development. Within the current context, when most economic activities are leading to ecological collapse, sustainability should be reprioritized with the help of the academic society, through the examples offered by applied research. The premises of this research were represented by bibliometric analyses and the results obtained have proven its importance, as well as the importance of certain scenarios involving solutions for improving the metabolism of nature.

In this paper, a moment-iteration method is introduced. The method is used to solve Lindley's integral equation for the GI/G/l queue. From several forms of this integral equation, we derive the first two moments of the waiting-time distribution, the waiting probability, and the percentiles of the conditional waiting time. Numerical evidence is given that the method yields excellent results. The flexibility of the method provides the opportunity to solve the GI/G/l queue for all interarrival time distributions of practical interest. To show that the moment-iteration method is generally applicable, we give some results for an (s, S)-model with order-size-dependent lead times and finite production capacity of the supplier.

The G/M/m queue with only s waiting places is studied. We start by studying the joint distribution of the number of customers present at time t and the time elapsing until the next arrival after t. This gives the asymptotic distribution of the number of customers at the moment of an arrival and at an arbitrary moment. Then waiting time and virtual waiting time distributions are easily obtained. For the G/M/1 queue also the transient solution is given. Finally the case s = ∞ is considered.

Density and population of bogor that keeps increasing will add the duty of government to provide more public means of mass. Transportation is a vital public facility. Public transport available in Bogor is a city transportation (public transportation) and buses. The existence of a number of public transportation totaling 3,412 units and 30 units of bus has been able to serve the needs of the community in transportation, but in terms of efficiency and comfort are still far from expected. Based on the results of Stated Preference regression models, we concluded that the most efficient mass transportation is city buses, and the most variable priority attribute passengers on a city bus is the bus occupancy, the bus waiting time efficiency, got a seat, bus convenience and cost/ bus rates. So the recommendation that we can give, the problem due to public transport in bogor can be solved by the means of mass transportation such as city buses.

Teaching metaphor is an important phenomenon which can be used to determine teachers’ perceptions regarding their job and their workplace (Turunen, 2003). This study was aimed to explore the metaphors of junior and senior teacher educators to get insights of what teaching was for them. A comparative analysis between the junior and senior teacher educators helped to understand how these metaphors changed over time. Data for the qualitative study were collected from the districts of Sargodha, Khushab and Mianwali situated in the province of Punjab, Pakistan. Fifty teacher educators teaching at postgraduate level participated in the study and filled in the survey questionnaire. The data were coded and analysed qualitatively. Six themes emerged from the data: religious obligations, economic activities, nature compatibility, life processes, emotional affiliations, and thought provoking activities.These themes were compatible with Chen’s (2013) classification of teachers’ personal metaphors. The implications of metaphors could be used to enhance critical thinking of teacher educators to improve the quality of education.
