In Sri Lankan Context, it is hardly possible to find an empirical study relating to time management and academic success. Globally many organizations, individuals practice time management to be effective. Hence it is very important to examine the nature of time management practice. Thus this study will fill the existing gap relating to achieving academic success through proper time management practices. The research problem of this study is what is the relationship exist among time management skills and academic success of university lecturers in state universities. The objective of this paper is to identify the impact of time management skills for academic success of university lecturers. This is a conceptual study, and it was done through a literature survey by following purposive sampling technique for the selection of literature. Most of the studies have found that time management is highly related to academic performance. However, most of them have done on the academic performance of the students, and there were very few studies relating to academic performance of the university lecturers. Hence it can be further suggested to conduct a study relating to identifying the relationship between academic performance and time management skills of university lecturers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20success" title="academic success">academic success</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20management%20skills" title=" time management skills"> time management skills</a>, <a href="https://publications.waset.org/abstracts/search?q=university%20lecturers" title=" university lecturers"> university lecturers</a> </p> <a href="https://publications.waset.org/abstracts/65744/the-role-of-time-management-skills-in-academic-performance-of-the-university-lecturers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65744.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59110</span> Analysis of Lead Time Delays in Supply Chain: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdel-Aziz%20M.%20Mohamed">Abdel-Aziz M.

It impacts both customer satisfactions as well as the total cost of inventory. This paper presents the result of a study on the analysis of the customer order lead-time for a multinational company. In the study, the lead time was divided into three stages: order entry, order fulfillment, and order delivery. A sample of size 2,425 order lines from the company records were considered for this study. The sample data includes information regarding customer orders from the time of order entry until order delivery. Data regarding the lead time of each sage for different orders were also provided. Summary statistics on lead time data reveals that about 30% of the orders were delivered after the scheduled due date. The result of the multiple linear regression analysis technique revealed that component type, logistics parameter, order size and the customer type have significant impact on lead time. Data analysis on the stages of lead time indicates that stage 2 consumes over 50% of the lead time. Pareto analysis was made to study the reasons for the customer order delay in each of the 3 stages. Recommendation was given to resolve the problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lead%20time%20reduction" title="lead time reduction">lead time reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20satisfaction" title=" customer satisfaction"> customer satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20quality" title=" service quality"> service quality</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a> </p> <a href="https://publications.waset.org/abstracts/31696/analysis-of-lead-time-delays-in-supply-chain-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31696.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">740</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59109</span> Execution Time Optimization of Workflow Network with Activity Lead-Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaoping%20Qiu">Xiaoping Qiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Binci%20You"> Binci You</a>, <a href="https://publications.waset.org/abstracts/search?q=Yue%20Hu"> Yue Hu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The executive time of the workflow network has an important effect on the efficiency of the business process. In this paper, the activity executive time is divided into the service time and the waiting time, then the lead time can be extracted from the waiting time. The executive time formulas of the three basic structures in the workflow network are deduced based on the activity lead time. Taken the process of e-commerce logistics as an example, insert appropriate lead time for key activities by using Petri net, and the executive time optimization model is built to minimize the waiting time with the time-cost constraints. Then the solution program-using VC++6.0 is compiled to get the optimal solution, which reduces the waiting time of key activities in the workflow, and verifies the role of lead time in the timeliness of e-commerce logistics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electronic%20business" title="electronic business">electronic business</a>, <a href="https://publications.waset.org/abstracts/search?q=execution%20time" title=" execution time"> execution time</a>, <a href="https://publications.waset.org/abstracts/search?q=lead%20time" title=" lead time"> lead time</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20model" title=" optimization model"> optimization model</a>, <a href="https://publications.waset.org/abstracts/search?q=petri%20net" title=" petri net"> petri net</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20workflow%20network" title=" time workflow network"> time workflow network</a> </p> <a href="https://publications.waset.org/abstracts/137019/execution-time-optimization-of-workflow-network-with-activity-lead-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137019.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59108</span> Circadian Clock and Subjective Time Perception: A Simple Open Source Application for the Analysis of Induced Time Perception in Humans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agata%20M.%20Ko%C5%82odziejczyk">Agata M.

Many studies have explored the relativity of time dilation using various approaches. However, the scientific and mathematical explanation of time dilation of moving things and light pulse clocks still has limited research. Therefore, this article examines relativity by utilizing scientific and mathematical approaches; the experience of moving things and light pulse clock ticks have been examined. The study revealed that the time elapsed for the same process is different for the different observers. Here, it showed that the time can be expressed in the form of a wave. In addition, the relative distance changes between the observers, and the observing subject time flows differently for the observer relative to the observing subject. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Einstein%27s%20special%20theory%20of%20relativity" title="Einstein's special theory of relativity">Einstein's special theory of relativity</a>, <a href="https://publications.waset.org/abstracts/search?q=reference%20frame" title=" reference frame"> reference frame</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20dilation" title=" time dilation"> time dilation</a>, <a href="https://publications.waset.org/abstracts/search?q=length%20contraction" title=" length contraction"> length contraction</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorentz%20transformation." title=" Lorentz transformation."> Lorentz transformation.</a> </p> <a href="https://publications.waset.org/abstracts/187451/a-distinct-approach-towards-relativity-and-time-dilation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187451.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">42</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59103</span> Simulation of Pedestrian Service Time at Different Delay Times</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imran%20Badshah">Imran Badshah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pedestrian service time reflects the performance of the facility, and it’s a key parameter to analyze the capability of facilities provided to serve pedestrians. The level of service of pedestrians (LOS) mainly depends on pedestrian time and safety. The pedestrian time utilized by taking a service is mainly influenced by the number of available services and the time utilized by each pedestrian in receiving a service; that is called a delay time. In this paper, we analyzed the simulated pedestrian service time with different delay times. A simulation is performed in AnyLogic by developing a model that reflects the real scenario of pedestrian services such as ticket machine gates at rail stations, airports, shopping malls, and cinema halls. The simulated pedestrian time is determined for various delay values. The simulated result shows how pedestrian time changes with the delay pattern. The histogram and time plot graph of a model gives the mean, maximum and minimum values of the pedestrian time. This study helps us to check the behavior of pedestrian time at various services such as subway stations, airports, shopping malls, and cinema halls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agent-based%20simulation" title="agent-based simulation">agent-based simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=anylogic%20model" title=" anylogic model"> anylogic model</a>, <a href="https://publications.waset.org/abstracts/search?q=pedestrian%20behavior" title=" pedestrian behavior"> pedestrian behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20delay" title=" time delay"> time delay</a> </p> <a href="https://publications.waset.org/abstracts/158989/simulation-of-pedestrian-service-time-at-different-delay-times" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158989.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">217</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59102</span> Project Time Prediction Model: A Case Study of Construction Projects in Sindh, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tauha%20Hussain%20Ali">Tauha Hussain Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Shabir%20Hussain%20Khahro"> Shabir Hussain Khahro</a>, <a href="https://publications.waset.org/abstracts/search?q=Nafees%20Ahmed%20Memon"> Nafees Ahmed Memon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accurate prediction of project time for planning and bid preparation stage should contain realistic dates. Constructors use their experience to estimate the project duration for the new projects, which is based on intuitions. It has been a constant concern to both researchers and constructors to analyze the accurate prediction of project duration for bid preparation stage. In Pakistan, such study for time cost relationship has been lacked to predict duration performance for the construction projects. This study is an attempt to explore the time cost relationship that would conclude with a mathematical model to predict the time for the drainage rehabilitation projects in the province of Sindh, Pakistan. The data has been collected from National Engineering Services (NESPAK), Pakistan and regression analysis has been carried out for the analysis of results. Significant relationship has been found between time and cost of the construction projects in Sindh and the generated mathematical model can be used by the constructors to predict the project duration for the upcoming projects of same nature. This study also provides the professionals with a requisite knowledge to make decisions regarding project duration, which is significantly important to win the projects at the bid stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BTC%20Model" title="BTC Model">BTC Model</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20time" title=" project time"> project time</a>, <a href="https://publications.waset.org/abstracts/search?q=relationship%20of%20time%20cost" title=" relationship of time cost"> relationship of time cost</a>, <a href="https://publications.waset.org/abstracts/search?q=regression" title=" regression"> regression</a> </p> <a href="https://publications.waset.org/abstracts/50762/project-time-prediction-model-a-case-study-of-construction-projects-in-sindh-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50762.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">388</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59101</span> Memory, Self, and Time: A Bachelardian Perspective </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Granado">Michael Granado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The French philosopher Gaston Bachelard’s philosophy of time is articulated in his two works on the subject, the Intuition of the Instant (1932) and his The Dialectic of Duration (1936). Both works present a systematic methodology predicated upon the assumption that our understanding of time has radically changed as a result of Einstein and subsequently needs to be reimagined. Bachelard makes a major distinction in his discussion of time: 1. Time as it is (physical time), 2. Time as we experience it (phenomenological time). This paper will focus on the second distinction, phenomenological time, and explore the connections between Bachelard’s work and contemporary psychology. Several aspects of Bachelard’s philosophy of time nicely complement our current understanding of memory and self and clarify how the self relates to experienced time. Two points, in particular, stand out; the first is the relative nature of subjective time, and the second is the implications of subjective time in the formation of the narrative self. Bachelard introduces two philosophical concepts to explain these points: rhythmanalysis and reverie. By exploring these concepts, it will become apparent that there is an undeniable link between memory, self, and time. Through the use of narrative self, the individual connects and links memories and time together to form a sense of personal identity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaston%20Bachelard" title="Gaston Bachelard">Gaston Bachelard</a>, <a href="https://publications.waset.org/abstracts/search?q=memory" title=" memory"> memory</a>, <a href="https://publications.waset.org/abstracts/search?q=self" title=" self"> self</a>, <a href="https://publications.waset.org/abstracts/search?q=time" title=" time "> time </a> </p> <a href="https://publications.waset.org/abstracts/127752/memory-self-and-time-a-bachelardian-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127752.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59100</span> Investigating the Effect of VR, Time Study and Ergonomics on the Design of Industrial Workstations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aydin%20Azizi">Aydin Azizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Poorya%20Ghafoorpoor%20Yazdi"> Poorya Ghafoorpoor Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the review of the studies on the ergonomics, virtual reality, and work measurement (time study) at the industrial workstations because each of these three individual techniques can be used to improve the design of workstations and task position.

In particular, it examines the impact of social-demographic features, household, job characteristics and trip qualities on individuals’ departure time choice. Departure time alternatives are presented as adjacent discrete time periods. The choice between these alternatives is done using a discrete choice model. Since a great deal of early morning trips and traffic congestion at that time of the day comprise work trips, the focus of this study is on the work trip over the entire day. Therefore, this study by using questionnaire of stated preference models users’ departure time choice affected by congestion pricing plan in downtown Tehran. Experimental results demonstrate efficient social-demographic impact on work trips’ departure time. These findings have substantial outcomes for the analysis of transportation planning. Particularly, the analysis shows that ignoring the effects of these variables could result in erroneous information and consequently decisions in the field of transportation planning and air quality would fail and cause financial resources loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modeling" title="modeling">modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=departure%20time" title=" departure time"> departure time</a>, <a href="https://publications.waset.org/abstracts/search?q=travel%20timing" title=" travel timing"> travel timing</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20of%20the%20day" title=" time of the day"> time of the day</a>, <a href="https://publications.waset.org/abstracts/search?q=congestion%20pricing" title=" congestion pricing"> congestion pricing</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation%20planning" title=" transportation planning"> transportation planning</a> </p> <a href="https://publications.waset.org/abstracts/19549/modeling-user-departure-time-choice-for-trips-in-urban-streets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">437</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59098</span> The Temporal Dimension of Narratives: A Construct of Qualitative Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ani%20Thomas">Ani Thomas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Every narrative is a temporal construct. Every narrative creates a qualitative experience of time for the viewer. The paper argues for the concept of a qualified time that emerges from the interaction between the narrative and the audience. The paper also challenges the conventional understanding of narrative time as either story time, real time or discourse time. Looking at narratives through the medium of Cinema, the study examines how narratives create and manipulate duration or durée, the qualitative experience of time as theorized by Henri Bergson. The paper further analyzes how Cinema and, by extension, narratives are nothing but Durée and the filmmaker, the artist of durée, who shape and manipulate the perception and emotions of the viewer through the manipulation and construction of durée. The paper draws on cinematic works to look at the techniques to demonstrate how filmmakers use, for example, editing, sound, compositional and production narratives etc., to create various modes of durée that challenge, amplify or unsettle the viewer’s sense of time. Bringing together the Viewer’s durée and exploring its interaction with the narrative construct, the paper explores the emergence of the new qualitative time, the narrative durée, that defines the audience experience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cinema" title="cinema">cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=time" title=" time"> time</a>, <a href="https://publications.waset.org/abstracts/search?q=bergson" title=" bergson"> bergson</a>, <a href="https://publications.waset.org/abstracts/search?q=duree" title=" duree"> duree</a> </p> <a href="https://publications.waset.org/abstracts/176250/the-temporal-dimension-of-narratives-a-construct-of-qualitative-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176250.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59097</span> Scenario Based Reaction Time Analysis for Seafarers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umut%20Tac">Umut Tac</a>, <a href="https://publications.waset.org/abstracts/search?q=Leyla%20Tavacioglu"> Leyla Tavacioglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Pelin%20Bolat"> Pelin Bolat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human factor has been one of the elements that cause vulnerabilities which can be resulted with accidents in maritime transportation. When the roots of human factor based accidents are analyzed, gaps in performing cognitive abilities (reaction time, attention, memory…) are faced as the main reasons for the vulnerabilities in complex environment of maritime systems. Thus cognitive processes in maritime systems have arisen important subject that should be investigated comprehensively. At this point, neurocognitive tests such as reaction time analysis tests have been used as coherent tools that enable us to make valid assessments for cognitive status. In this respect, the aim of this study is to evaluate the reaction time (response time or latency) of seafarers due to their occupational experience and age. For this study, reaction time for different maneuverers has been taken while the participants were performing a sea voyage through a simulator which was run up with a certain scenario.

The current traffic signalling system is a fixed-time system that is inefficient if one lane is more functional than the others. A structure for an intelligent traffic control system is being designed to address this issue. When traffic density is higher on one side of a junction, the signal's green time is extended in comparison to the regular time. This study suggests a technique in which the signal's time duration is assigned based on the amount of traffic present at the time.

We observe that the inclusion of log-volatility into the time-varying parameter estimation significantly improves forecasting which is facilitated via maximum likelihood estimation.

How humans make decisions in dangerous driving situations like moral dilemmas can contribute to developing acceptable ethical principles for autonomous vehicles (AVs). This study uses a driving simulator to investigate whether drivers make utilitarian choices (choices that maximize lives saved and minimize harm) in unavoidable automobile accidents (moral dilemmas) with time pressure manipulated. This study also investigates how impulsiveness influences drivers’ behavior in moral dilemmas. Manipulating time pressure results in collisions that occur at varying time intervals (4 s, 5 s, 7s). Manipulating time pressure helps investigate how time pressure may influence drivers’ response behavior. Thirty-one undergraduates participated in this study using a STISM driving simulator to respond to driving moral dilemmas. The results indicated that the percentage of utilitarian choices generally increased when given more time to respond (from 4 s to 7 s). Additionally, participants in vehicle scenarios preferred responding right over responding left. Impulsiveness did not influence utilitarian choices. However, as time pressure decreased, response time increased. Findings have potential implications and applications on the regulation of driver assistance technologies and AVs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=time%20pressure" title="time pressure">time pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=automobile%20moral%20dilemmas" title=" automobile moral dilemmas"> automobile moral dilemmas</a>, <a href="https://publications.waset.org/abstracts/search?q=impulsiveness" title=" impulsiveness"> impulsiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=reaction%20time" title=" reaction time"> reaction time</a> </p> <a href="https://publications.waset.org/abstracts/177790/investigation-of-time-pressure-and-instinctive-reaction-in-moral-dilemmas-while-driving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177790.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">60</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59092</span> Reactivity Study on South African Calcium Based Material Using a pH-Stat and Citric Acid: A Statistical Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hilary%20Rutto">Hilary Rutto</a>, <a href="https://publications.waset.org/abstracts/search?q=Mbali%20Chiliza"> Mbali Chiliza</a>, <a href="https://publications.waset.org/abstracts/search?q=Tumisang%20Seodigeng"> Tumisang Seodigeng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study on reactivity of calcined calcium-based material is very important in dry flue gas desulphurisation (FGD) process, so as to produce absorbent with high sulphur dioxide capture capacity during the hydration process.

In this study, the reactivity was measured using a pH stat apparatus and also confirming the result by performing citric acid reactivity test. The reactivity was calculated using the shrinking core model. Based on the experiments, a mathematical model is developed to correlate the effect of time and temperature to the reactivity of absorbent. The calcination process variables were temperature (700 -1000°C) and time (1-6 hrs). It was found that reactivity increases with an increase in time and temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reactivity" title="reactivity">reactivity</a>, <a href="https://publications.waset.org/abstracts/search?q=citric%20acid" title=" citric acid"> citric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=calcination" title=" calcination"> calcination</a>, <a href="https://publications.waset.org/abstracts/search?q=time" title=" time"> time</a> </p> <a href="https://publications.waset.org/abstracts/57923/reactivity-study-on-south-african-calcium-based-material-using-a-ph-stat-and-citric-acid-a-statistical-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57923.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59091</span> Barriers towards Effective Participation in Physically Oriented Leisure Time Activities: A Case Study of Federal College of Education, Pankshin Plateau State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mulak%20Moses%20Yokdi">Mulak Moses Yokdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Correct use of leisure time has suffered neglect in our society and the people ignorantly think that the trend does not matter. The researcher felt concerned about the issue and went on to find out why using FCE, Pankshin workers as a case study. Four hypotheses were used, considering such variables as leadership, traditional activities, stress due to work pressure and time constraint. The participants selected for the study were one hundred and ten members of FCE, Pankshin staff. A self-developed questionnaire was the instrument used. Chi-square (x2) was employed to test the hypotheses at P = 0.005; df = 3. The statistics of percentages was also used to describe the situation as implicated by the data. The results showed that all hypotheses were significant (P = 0.05). It was concluded that the four variables were impediments to effective participation in physically oriented leisure time activities among the FCE, Staff. Based on the findings, it was recommended that the FCE should get good leadership, create good awareness for people to understand why they should be effectively involved in physically oriented leisure time activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=barriers" title="barriers">barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20participation" title=" effective participation"> effective participation</a>, <a href="https://publications.waset.org/abstracts/search?q=leisure%20time" title=" leisure time"> leisure time</a>, <a href="https://publications.waset.org/abstracts/search?q=physically%20oriented" title=" physically oriented"> physically oriented</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20pressure" title=" work pressure"> work pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20constraint" title=" time constraint"> time constraint</a> </p> <a href="https://publications.waset.org/abstracts/36747/barriers-towards-effective-participation-in-physically-oriented-leisure-time-activities-a-case-study-of-federal-college-of-education-pankshin-plateau-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59090</span> The Study on Corpse Floating Time in Shanghai Region of China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hang%20Meng">Hang Meng</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Bin%20Liu"> Wen-Bin Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bi%20Xiao"> Bi Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Kai-Jun%20Ma"> Kai-Jun Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian-Hui%20Xie"> Jian-Hui Xie</a>, <a href="https://publications.waset.org/abstracts/search?q=Geng%20Fei"> Geng Fei</a>, <a href="https://publications.waset.org/abstracts/search?q=Tian-Ye%20Zhang"> Tian-Ye Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu-Yi%20Xu"> Lu-Yi Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Chuan%20Zhang"> Dong-Chuan Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The victims in water are often found in the coastal region, along river region or the region with lakes. In China, the examination for the bodies of victims in the water is conducted by forensic doctors working in the public security bureau. Because the enter water time for most of the victims are not clear, and often lack of monitor images and other information, so to find out the corpse enter water time for victims is very difficult. After the corpse of the victim enters the water, it sinks first, then corruption gas produces, which can make the density of the corpse to be less than water, and thus rise again. So the factor that determines the corpse floating time is temperature. On the basis of the temperature data obtained in Shanghai region of China (Shanghai is a north subtropical marine monsoon climate, with an average annual temperature of about 17.1℃. The hottest month is July, the average monthly temperature is 28.6℃, and the coldest month is January, the average monthly temperature is 4.8℃). This study selected about 100 cases with definite corpse enter water time and corpse floating time, analyzed the cases and obtained the empirical law of the corpse floating time. For example, in the Shanghai region, on June 15th and October 15th, the corpse floating time is about 1.5 days. In early December, the bodies who entered the water will go up around January 1st of the following year, and the bodies who enter water in late December will float in March of next year. The results of this study can be used to roughly estimate the water enter time of the victims in Shanghai. Forensic doctors around the world can also draw on the results of this study to infer the time when the corpses of the victims in the water go up. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corpse%20enter%20water%20time" title="corpse enter water time">corpse enter water time</a>, <a href="https://publications.waset.org/abstracts/search?q=corpse%20floating%20time" title=" corpse floating time"> corpse floating time</a>, <a href="https://publications.waset.org/abstracts/search?q=drowning" title=" drowning"> drowning</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic%20pathology" title=" forensic pathology"> forensic pathology</a>, <a href="https://publications.waset.org/abstracts/search?q=victims%20in%20the%20water" title=" victims in the water"> victims in the water</a> </p> <a href="https://publications.waset.org/abstracts/81023/the-study-on-corpse-floating-time-in-shanghai-region-of-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81023.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59089</span> Nonstationarity Modeling of Economic and Financial Time Series</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Slim">C.

We formalize the problem of nonstationary processes with numerical simulations and take stock of their statistical characteristics. The theoretical aspects of some of the most common unit root tests will be discussed. We detail the specification of the tests, showing the advantages and disadvantages of each.

In this paper, we study how to answer the General Time-Dependent Sequenced Route queries. Given the origin and destination of a user over a time-dependent road network graph, an ordered list of categories of interests and a departure time interval, our goal is to find the minimum travel time path along with the best departure time that minimizes the total travel time from the source location to the given destination passing through a sequence of points of interests belonging to each of the specified categories of interest. The challenge of this problem is the added complexity to the optimal sequenced route queries, where we assume that first the road network is time dependent, and secondly the user defines a departure time interval instead of one single departure time instance. For processing general time-dependent sequenced route queries, we propose two solutions as Discrete-Time and Continuous-Time Sequenced Route approaches, finding approximate and exact solutions, respectively. Our proposed approaches traverse the road network based on A*-search paradigm equipped with an efficient heuristic function, for shrinking the search space. Extensive experiments are conducted to verify the efficiency of our proposed approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trip%20planning" title="trip planning">trip planning</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20dependent" title=" time dependent"> time dependent</a>, <a href="https://publications.waset.org/abstracts/search?q=sequenced%20route%20query" title=" sequenced route query"> sequenced route query</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20networks" title=" road networks"> road networks</a> </p> <a href="https://publications.waset.org/abstracts/72792/general-time-dependent-sequenced-route-queries-in-road-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72792.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">327</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59087</span> Modeling User Departure Time Choice for Work Trips in High Traffic Suburban Roads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Sayyad%20Hagh%20Shomar">Saeed Sayyad Hagh Shomar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modeling users’ decisions on departure time choice is the main motivation for this research. In particular, it examines the impact of social-demographic features, household, job characteristics and trip qualities on individuals’ departure time choice. Departure time alternatives are presented as adjacent discrete time periods. The choice between these alternatives is done using a discrete choice model. Since a great deal of early morning trips and traffic congestion at that time of the day comprise work trips, the focus of this study is on the work trip over the entire day. Therefore, this study by using the users’ stated preference in questionnaire models users’ departure time choice affected by congestion pricing schemes in high traffic suburban entrance roads of Tehran. The results demonstrate efficient social-demographic impact on work trips’ departure time. These findings have substantial outcomes for the analysis of transportation planning. Particularly, the analysis shows that ignoring the effects of these variables could result in erroneous information and consequently decisions in the field of transportation planning and air quality would fail and cause financial resources loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=congestion%20pricing" title="congestion pricing">congestion pricing</a>, <a href="https://publications.waset.org/abstracts/search?q=departure%20time" title=" departure time"> departure time</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=travel%20timing" title=" travel timing"> travel timing</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20of%20the%20day" title=" time of the day"> time of the day</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation%20planning" title=" transportation planning"> transportation planning</a> </p> <a href="https://publications.waset.org/abstracts/93381/modeling-user-departure-time-choice-for-work-trips-in-high-traffic-suburban-roads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93381.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">300</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59086</span> Controlling the Process of a Chicken Dressing Plant through Statistical Process Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jasper%20Kevin%20C.%20Dionisio">Jasper Kevin C.

Unsay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a manufacturing firm, controlling the process ensures that optimum efficiency, productivity, and quality in an organization are achieved. An operation with no standardized procedure yields a poor productivity, inefficiency, and an out of control process. This study focuses on controlling the small intestine processing of a chicken dressing plant through the use of Statistical Process Control (SPC). Since the operation does not employ a standard procedure and does not have an established standard time, the process through the assessment of the observed time of the overall operation of small intestine processing, through the use of X-Bar R Control Chart, is found to be out of control. In the solution of this problem, the researchers conduct a motion and time study aiming to establish a standard procedure for the operation. The normal operator was picked through the use of Westinghouse Rating System. Instead of utilizing the traditional motion and time study, the researchers used the X-Bar R Control Chart in determining the process average of the process that is used for establishing the standard time. The observed time of the normal operator was noted and plotted to the X-Bar R Control Chart. Out of control points that are due to assignable cause were removed and the process average, or the average time the normal operator conducted the process, which was already in control and free form any outliers, was obtained. The process average was then used in determining the standard time of small intestine processing. As a recommendation, the researchers suggest the implementation of the standard time established which is with consonance to the standard procedure which was adopted from the normal operator. With that recommendation, the whole operation will induce a 45.54 % increase in their productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=motion%20and%20time%20study" title="motion and time study">motion and time study</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20controlling" title=" process controlling"> process controlling</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20process%20control" title=" statistical process control"> statistical process control</a>, <a href="https://publications.waset.org/abstracts/search?q=X-Bar%20R%20Control%20chart" title=" X-Bar R Control chart"> X-Bar R Control chart</a> </p> <a href="https://publications.waset.org/abstracts/78980/controlling-the-process-of-a-chicken-dressing-plant-through-statistical-process-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78980.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59085</span> A Hyperexponential Approximation to Finite-Time and Infinite-Time Ruin Probabilities of Compound Poisson Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20T.%20Payandeh%20Najafabadi">Amir T.
