A Hybrid Approach Based on Qualitative and Quantitative Techniques for Analyzing Last-Mile Parcel Delivery
(Springer India, 2025) Kanik, Zehra B.; Eriskan, Sibel; Soysal, Mehmet; Omurgonulsen, Mine
Operational excellence in last-mile delivery is becoming increasingly challenging, highlighting the need for a strategic assessment framework to improve decision-making processes. This study aims to provide a strategic assessment tool for last-mile parcel delivery processes, which are critical in terms of service levels, cost management and sustainability. The study presents a comprehensive approach to identify and prioritise feasible strategies by combining qualitative data obtained from expert opinions with Strengths, Weaknesses, Opportunities, and Threats analysis (SWOT) and Multi-Criteria Decision-Making (MCDM) methods. As a result of semi-structured interviews conducted with nine experts, 27 strategic criteria were identified and classified under SWOT dimensions. The 10 strategies developed during the interviews were evaluated by using the Intuitionistic Fuzzy Set (IFS) approach, which considers expert reliability, the Full Consistency Method (FUCOM) for weighting, and the Complex Proportional Assessment (COPRAS) technique for final ranking. There is a clear gap in the literature regarding critical criteria and strategies for last-mile delivery in developing economies. Since it is not possible to implement all strategies simultaneously due to limited resources, the strategies proposed in this study have been prioritised according to their relative importance. While expert-based evaluations in the literature typically assume that experts have equal influence, this study differs from the literature by weighting experts based on their level of experience. This approach not only addresses the gap in strategy and criterion development in the literature but also offers a more realistic and feasible approach from an implementation perspective. The findings show that all strategies are meaningful in improving last-mile performance, but their impact levels vary. "Developing public and corporate strategies for environmental sustainability" stands out as the highest priority strategy with a performance index of 100 points, while "Incorporating parcel transportation-related topics into logistics management education" is considered as the lowest priority strategy with 91.94 points. Limitations of this study arise from the niche nature of the sector and the small sample size.

About Fractional Calculus of Singular Lagrangians
(Fuji Technology Press Ltd, 2005) Baleanu, Dumitru
In this paper the solutions of the fractional Euler-Lagrange equations corresponding to singular fractional Lagrangians were examined. We observed that if a Lagrangian is singular in the classical sense, it remains singular after being fractionally generalized. The fractional Lagrangian is non-local but its gauge symmetry was preserved despite complexity of equations in fractional cases. We generalized four examples of singular Lagrangians admitting gauge symmetry in fractional case and found solutions to corresponding Euler-Lagrange equations.

About Lagrangian Formulation of Classical Fields Within Riemann-Liouville Fractional Derivatives
(American Society of Mechanical Engineers, 2005) Baleanu, D.; Muslih, S.I.
Recently, an extension of the simplest fractional problem and the fractional variational problem of Lagrange was obtained by Agrawal. The first part of this study presents the fractional Lagrangian formulation of mechanical systems and introduce the Levy path integral. The second part is an extension to Agrawal's approach to classical fields with fractional derivatives. The classical fields with fractional derivatives are investigated by using the Lagrangian formulation. The case of the fractional Schrödinger equation is presented. Copyright © 2005 by ASME.
About Nanometer Sized Analogues of Basic Electronic and Optical Components
(Ieee, 2008) Quandt, A.; Özdoǧan, C.; Ferrari, M.; Speranza, G.
We discuss a downsizing of optical components into the nanometer range. It presupposes the substitution of photons by ballistic electrons, but it also requires a simple and robust concept to assemble the analogues of basic electronic and optical components on such a tiny length scale. Here, one of the most promising candidate schemes employs graphene as a basic nanosubstrate. We elucidate the suggested behaviour of graphene as an electronic metamaterial [1], and show that other desired electronic or optical functionalities may be obtained through a patterning with sub-nanometer sized boron clusters [2]. © 2008 IEEE.

In given applications we need to know where neutrons are in an apparatus, what direction they are moving, and how fast they are going. In this manuscript the Legendre polynomial approximation method F N was applied to the one dimensional slab geometry neutron transport equation. © 2011 by ASME.
The Adaptation of Modern Housing Heritage: Authenticity and Integrity in the Case of Cité Modèle
(Univ Politecnica Valencia, Editorial Upv, 2024) Ozmen, Ayca
The post-war social housing estate, Cit & eacute; Mod & egrave;le (Model City) in Laeken-Brussel (BE) was designed with CIAM principles in 1950s as a high-rise modern residential district where different types of dwellings integrated with car-free zones, wide green areas and various social facilities. Today it is an exceptional urban site in the history of modern architecture in Belgium. However, physical deterioration and socio-economic vulnerability necessitated the adaptation of the settlement in 2005, leading to the preparation of a masterplan which included a twelve-year of rehabilitation programme. Different types of interventions, both prior to this masterplan and in accordance with it, have led to changes in different attributes of this living heritage site. This paper aims to discuss the impacts of various conservation and adaptation strategies on the authenticity and integrity of the modern housing heritage, while considering expanding and questioning their definitions. The methodology includes literature review, field surveys, case study analyses, and comparative tabular evaluations to explore the dimensions of authenticity and integrity in modern housing heritage. The research on this case study has the potential to address a notable question in the literature on both architectural conservation and design based on the dialogue between continuity and change, and the re-interpretation of authenticity and integrity regarding a living modern heritage site.

Adaptive Modeling of Landslide Susceptibility Using Analytical Hierarchy Process and Multi-Objective Decision Optimization
(Elsevier Sci Ltd, 2025) Mao, Yimin; Zhu, Licai; Chen, Junde; Nanehkaran, Yaser A.
This study develops a detailed landslide susceptibility map for Kermanshah province, Iran, by analyzing field surveys, historical data, and remote sensing. Fifteen key factors-such as geomorphology, geology, climate, seismicity, and human activities-were identified and ranked using Analytical Hierarchy Process (AHP) and Multi-Objective Decision Optimization (MODO) within a GIS framework. The analysis classifies landslide risk into five categories: very high (18.4%), high (33.98%), moderate (24.19%), low (14.36%), and very low (9.07%). Pixel rate assessment confirmed the map's accuracy, showing that eastern and northeastern regions are particularly prone to landslides, with a substantial portion of the province at moderate to high risk. The study recommends using this map to guide targeted risk mitigation and land-use planning efforts to reduce landslide impacts on vulnerable areas. (c) 2024 COSPAR. Published by Elsevier B.V.

Aggregation Operators for Interval-Valued Intuitionistic Fuzzy Hypersoft Set With Their Application in Material Selection
(Hindawi Ltd, 2022) Zulqarnain, Rana Muhammad; Siddique, Imran; Jarad, Fahd; Karamti, Hanen; Iampan, Aiyared
The intuitionistic fuzzy hypersoft set (IFHSS) is the most generalized form of the intuitionistic fuzzy soft set used to resolve uncertain and vague data in the decision-making process, considering the parameters' multi-sub-attributes. Aggregation operators execute a dynamic role in assessing the two prospect sequences and eliminating anxieties from this perception. This paper prolongs the IFHSS to interval-valued IFHSS (IVIFHSS), which proficiently contracts with hesitant and unclear data. It is the most potent technique for incorporating insecure data into decision-making (DM). The main objective of this research is to develop the algebraic operational laws for IVIFHSS. Furthermore, using the algebraic operational law, some aggregation operators (AOs) for IVIFHSS have been presented, such as interval-valued intuitionistic fuzzy hypersoft weighted average (IVIFHSWA) and interval-valued intuitionistic fuzzy hypersoft weighted geometric (IVIFHSWG) operators with their essential properties. Multi-criteria group decision-making (MCGDM) technique is vigorous for material selection. However, conventional methods of MCGDM regularly provide inconsistent results. Based on the expected AOs, industrial enterprises propose a robust MCGDM material selection method to meet this shortfall. The real-world application of the planned MCGDM method for cryogenic storing vessel material selection (MS) is presented. The implication is that the designed model is more efficient and consistent in handling information based on IVIFHSS.

An Alternative Mean Reversion Test for Interest Rates
(Central Bank Republic Turkey, 2018) Ozel, Ozgur; Ilalan, Deniz
A number of empirical studies assert that interest rates are governed by unit root processes rejecting any form of reversion to a long term mean by resorting to certain tests, among which the Augmented Dickey Fuller (ADF) is the most widely used one. In this study, we propose an alternative testing methodology that can be applied along with ADF test, in the sense that there are times where it can capture stationarity when the other fails to do so. Moreover, our test has more power than ADF test. As an application to real-data, we consider 10-year US and Turkish T-bond rates. (C) 2017 Central Bank of The Republic of Turkey.

An Integrated Framework on Soundscape Perception and Spatial Experience by Adapting Post-Occupancy Evaluation Methodology
(Sage Publications Inc, 2018) Aburawis, Ayad A. Mohamed; Yorukoglu, Papatya Nur Dokmeci
The effecting factors of soundscape perception and space experience have a very close relationship. This study aims to synthesize the diversity of soundscape classifications and schemes and unify such factorial variations in order to develop an integrated framework for soundscape perception and spatial experience within a systematic review of recent progress and by adapting post-occupancy evaluation methodology. First, factors under soundscape perception and space experience are reviewed in detail and merged to form conceptual classification models. Six soundscape perception factors are formed as (1) sonic, (2) spatial, (3) temporal, (4) psychological, (5) behavioural and (6) personal. Similarly, five space experience factors are formed as (1) user, (2) usage, (3) architectural design, (4) social context and (5) physical environment. All related items in the literature are presented and the sub-items under each factor are exemplified. Second, factors under the merged conceptual models are integrated by considering occupants' experience of space regarding their variance in perception of soundscapes through acoustical post-occupancy evaluation. An adapted study design is proposed under indicative, investigative and diagnostic stages of the post-occupancy evaluation by presenting the methods, data types and factorial correlations for each stage.
Analysis of Condensation Risk in a Wall Section in the Context of Climate Change Scenarios
(Horizon Research Publishing, 2024) Saricioglu, P.; Aycam, İ.; Harputlugil, G.U.
The effects of climate change can be seen in many areas. Although there are many causes of climate change (changes in solar radiation, differences in the Earth’s orbit, continental shifts and changes in the atmosphere), one of the most noticeable causes in the 21st century is anthropogenic effects. One area where these impacts can be seen is the construction sector in buildings and building façades. Climate change will change assumptions about façade design in the coming decades. For this reason, it is important to develop climate change projections for existing and new buildings. For this purpose, the literature has three basic climate models. Therefore, the aim of this study is to compare the condensation risk for a wall section in a city with a humid-temperate climate (Zonguldak, Turkey) using HadGEM, MPI and GFDL climate models according to RCP8.5 scenario data for the historical period 2015 and the future year 2081. Within the scope of the study, the average temperatures and relative humidity values were obtained from GDM (General Directorate of Meteorology) by choosing 2081 and 2015, which are frequently used in climate change studies based on the literature. In the method, the projection results for the historical and future periods were compared and became the basis for the next stage. In the next step, based on the literature, the condensation control in the wall section was compared for the past and future using the Glaser method, which is frequently used in condensation control in wall sections and included in the TS 825 standard created for Turkey, which corresponds to EN ISO 13788 and DIN 4108 standards. According to the results, the humidity and temperature fluctuations in the future period and increase in averages are important problems that need to be addressed in detail in façade design and the impact of condensation risk. Therefore, according to the condensation control calculations made in the wall section detail, condensation risk occurs in the future period. Consequently, assumptions in façade design will need to change for existing and future buildings to accommodate condensation risk. © 2024 by authors, all rights reserved.

Analysis of Delay Factors for Voice Over Wimax
(Ieee, 2008) Safak, A.; Preveze, B.
This paper presents the results of our computer simulation for delays experienced by voice packets over WiMAX 802.16e protocol running over an enterprise packet network connected to public internet. In the simulation we analyzed the effect of packet size, core network link speed, internet service provider link speed, wireless network link speed, wireless distance, base station range, and distance in internet parameters that effect the amount of delay in a WiMAX embedded IP network. In this study, all the delay parameters are fixed to their default values and current parameter values are changed so that the delay is varied between minimum and maximum values in uniformly distributed 100 steps and the delay is plotted in each step. Total fixed delays can be considered as minimum delay and variable delay corresponds to the maximum delay that can occur under the given conditions. All other fixed and variable delay parameters such as switching delays, packetization delays, contention delays and the delays caused by buffers etc. are also taken into account. The results indicate that among these delays WiMAX base station range and the number of base stations play the most decisive role. © 2008 IEEE.

(Univ Rijeka, Fac Maritime Studies, 2024) Gurses, Cemre; Temiz, Dilek; Yurtseven, Omer; Kanik, Zehra B.; Gokmen, Aytac
The main objective of this study is to investigate the effect of freight transportation on foreign trade in the Turkish maritime transportation sector. Data gathered from the Turkish Statistical Institute and the Ministry of Transport and Infrastructure's official websites, between the years 2013 and 2023, were utilized and time series analysis was conducted. The Industrial Production Index was used as a proxy for economic expansion. This research used five variables, all shown in logarithmic form (Export, Import, Volume, Handling, and Index). Unit root tests were done to examine the stationarity of the series. Regression analysis was conducted utilizing the Ordinary Least Squares (OLS) method to ascertain the short-term direction of the relationship between the variables. The findings from the Toda-Yamamoto causality test align with those derived from OLS and affirm that within the maritime sector, sea freight transportation exerts a positive impact on foreign trade, particularly in the short term.

(TUBITAK, 2025) Orman, R.; Cağıltay, N.E.; Cakır, H.
Participants’ performance is one of the critical factors for the success of the platforms. There is a lot of data in Massive Open Online Course platforms that are free and open to everyone, and due to this large amount of educational data, it is difficult to make accurate predictions and inferences. The primary purpose of this research is to conduct a literature review to discover the existing Educational Data Mining methods and techniques used to analyze Massive Open Online Course data. For this purpose, the focus is on the source from which the data is collected, which Educational Data Mining methods and techniques are used, and which tools are used in the analysis to compare different approaches. A total of 32 articles published between 2013-2024 were included in the scope of the study. According to the findings, there are many algorithms used for Educational Data Mining methods and techniques in the analysis of Massive Open Online Course data. The most preferred algorithm in the studies is “K-Means”, followed by “Support Vector Machines”, “Decision Trees” and “Random Forest”. Coursera and Edx are among the platforms used and preferred worldwide. It is anticipated that making the data available on these platforms public will contribute to further research and guide studies in the education field. Privacy and ethics also come to the fore within the scope of open data publication. In this context, developing some standards and new approaches to share data with researchers in a standard form that does not include privacy violations will significantly contribute to studies conducted in this field. © 2025, TUBITAK.
