It causes substantial cost to carriers, which inadvertently adds to the prices of consumer goods. The virtual container yard is rooted in the fundamentals of container interchange between carriers. If carriers opt to interchange their excess containers with those who are deficit, a substantial part of the empty reposition cost could be eliminated. Unlike in other types of ships, cargo cannot be directly loaded to a container ship. Slots and containers are supplementary components; thus, without containers, a carrier cannot ship cargo if the containers are not available and vice versa. Few decades ago, carriers recognized slot (the unit of space in a container ship) interchange as a viable solution for the imbalance of shipping space. Carriers interchange slots among them and it also increases the advantage of scale of economies in container shipping. Some of these service agreements between mega carriers have provisions to interchange containers too. However, the interchange mechanism is still not popular among carriers for containers. This is the paradox that prevails in the liner shipping industry. At present, carriers reposition their excess empty containers to areas where they are in demand. This research applied factor analysis statistical method. The paper reveals that five major components may influence the virtual container yard namely organisation, practice and culture, legal and environment, international nature, and marketing. There are 12 variables that may impact the virtual container yard, and these are explained in the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20container%20yard" title="virtual container yard">virtual container yard</a>, <a href="https://publications.waset.org/abstracts/search?q=shipping" title=" shipping"> shipping</a>, <a href="https://publications.waset.org/abstracts/search?q=imbalance" title=" imbalance"> imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=inventory" title=" inventory"> inventory</a> </p> <a href="https://publications.waset.org/abstracts/97126/the-virtual-container-yard-identifying-the-persuasive-factors-in-container-interchange" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97126.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">196</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">1152</span> An Empirical Analysis of the Freight Forwarders’ Buying Behaviour: Implications for the Ocean Container Carriers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peter%20Dzakah%20Fanam">Peter Dzakah Fanam</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20O.%20Nguyen"> Hong O.

This study analysed the buying decisions of the freight forwarders and validated the process of stages that the freight forwarders’ pass through before choosing an ocean container carrier. Factor analysis was applied to data collected from 105 freight forwarding companies to unveil the influential factors the freight forwarders’ consider important when selecting an ocean container carrier. This study did not only analysed the buying behaviour of the freight forwarders but also unveiled the influential factors affecting the competitiveness of the ocean container carriers in their market share maximisation. Furthermore, the study have made a methodological contribution that helps in better understanding of the critical factors influencing the selection of the ocean container carriers from the freight forwarders’ perspective. The implications of the freight forwarders’ buying behaviour is important to the ocean container carriers because it have severe effect on the market share of the ocean container carriers and the percentage of customers they control within the liner shipping sector. The findings of this study will help the ocean container carriers to formulate relevant marketing strategies in attracting the freight forwarders in purchasing the liner shipping service. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ocean%20carrier" title="ocean carrier">ocean carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=freight%20forwarder" title=" freight forwarder"> freight forwarder</a>, <a href="https://publications.waset.org/abstracts/search?q=buying%20behaviour" title=" buying behaviour"> buying behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=influential%20factors" title=" influential factors"> influential factors</a> </p> <a href="https://publications.waset.org/abstracts/53684/an-empirical-analysis-of-the-freight-forwarders-buying-behaviour-implications-for-the-ocean-container-carriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53684.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">251</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">1151</span> Mitigating the Cost of Empty Container Repositioning through the Virtual Container Yard: An Appraisal of Carriers’ Perceptions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Edirisinghe">L.

The virtual container yard is a novel strategy underpinning the container interchange between carriers that could substantially reduce this ever-increasing shipping cost. This paper evaluates the shipping industry perception of the virtual container yard using chi-square tests. It examines if the carriers perceive that the selected independent variables, namely culture, organization, decision, marketing, attitudes, legal, independent, complexity, and stakeholders of carriers, impact the efficiency and benefits of the virtual container yard. There are two major findings of the research. Firstly, carriers view that complexity, attitudes, and stakeholders may impact the effectiveness of container interchange and may influence the perceived benefits of the virtual container yard. Secondly, the three factors of legal, organization, and decision influence only the perceived benefits of the virtual container yard. Accordingly, the implementation of the virtual container yard will be influenced by six key factors, namely complexity, attitudes, stakeholders, legal, organization and decision. Since the virtual container yard could reduce overall shipping costs, it is vital to examine the carriers’ perception of this concept. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20container%20yard" title="virtual container yard">virtual container yard</a>, <a href="https://publications.waset.org/abstracts/search?q=imbalance" title=" imbalance"> imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=inventory" title=" inventory"> inventory</a> </p> <a href="https://publications.waset.org/abstracts/95757/mitigating-the-cost-of-empty-container-repositioning-through-the-virtual-container-yard-an-appraisal-of-carriers-perceptions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95757.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">194</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">1150</span> Refactoring Object Oriented Software through Community Detection Using Evolutionary Computation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Nagarani">R. Nagarani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An intrinsic property of software in a real-world environment is its need to evolve, which is usually accompanied by the increase of software complexity and deterioration of software quality, making software maintenance a tough problem. Refactoring is regarded as an effective way to address this problem. Many refactoring approaches at the method and class level have been proposed. But the extent of research on software refactoring at the package level is less. This work presents a novel approach to refactor the package structures of object oriented software using genetic algorithm based community detection. It uses software networks to represent classes and their dependencies. It uses a constrained community detection algorithm to obtain the optimized community structures in software networks, which also correspond to the optimized package structures. It finally provides a list of classes as refactoring candidates by comparing the optimized package structures with the real package structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20detection" title="community detection">community detection</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20network" title=" complex network"> complex network</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=package" title=" package"> package</a>, <a href="https://publications.waset.org/abstracts/search?q=refactoring" title=" refactoring"> refactoring</a> </p> <a href="https://publications.waset.org/abstracts/31191/refactoring-object-oriented-software-through-community-detection-using-evolutionary-computation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31191.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">418</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">1149</span> Development of a Distance Training Package on Production of Handbook and Report Writing for Innovative Learning and Teaching for Vocational Teachers of Office of the Vocational Education Commission</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Petchpong%20Mayukhachot">Petchpong Mayukhachot</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purposes of this research were (1) to develop a distance training package on topic of Production of Handbook and Report writing for innovative learning and teaching for Vocational Teachers of Office of The Vocational Education Commission; (2) to study the effects of using the distance training package on topic Production of Handbook and Report writing for innovative learning and teaching for Vocational Teachers of Office of The Vocational Education Commission. and (3) to study the samples’ opinion on the distance training package on topic Production of Handbook and Report writing for innovative learning and teaching for Vocational Teachers of Office of The Vocational Education Commission Research and Development was used in this research.

Because chip package is placed in isolated devices based on IP67 waterproof standard, there is no air circulation and the heat dissipation is a challenge. In this paper, the author successfully modeled a chip package which various interposer materials such as silicon, glass and organics. Computational fluid dynamics (CFD) was utilized to analyze the thermal performance of chip package in the case of considering comprehensive heat transfer modes: conduction, convection and radiation, which proposes equivalent heat dissipation.

It is widely used by the package carrier companies’ distribution centers. The main goal of applying the TSP in courier organizations is to minimize the time that it takes for the courier in each trip to deliver or pick up the shipments during a day. In this article, an optimization model is constructed to create a new TSP variant to optimize the routing in a courier organization with a consideration of congestion in Amman, the capital of Jordan. Real data were collected by different methods and analyzed. Then, concert technology - CPLEX was used to solve the proposed model for some random generated data instances and for the real collected data. At the end, results have shown a great improvement in time compared with the current trip times, and an economic study was conducted afterwards to figure out the impact of using such models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=travel%20salesman%20problem" title="travel salesman problem">travel salesman problem</a>, <a href="https://publications.waset.org/abstracts/search?q=congestions" title=" congestions"> congestions</a>, <a href="https://publications.waset.org/abstracts/search?q=pick-up" title=" pick-up"> pick-up</a>, <a href="https://publications.waset.org/abstracts/search?q=integer%20programming" title=" integer programming"> integer programming</a>, <a href="https://publications.waset.org/abstracts/search?q=package%20carriers" title=" package carriers"> package carriers</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20engineering" title=" service engineering"> service engineering</a> </p> <a href="https://publications.waset.org/abstracts/73379/optimizing-logistics-for-courier-organizations-with-considerations-of-congestions-and-pickups-a-courier-delivery-system-in-amman-as-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73379.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">429</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">1144</span> Relationship Salt Sensitivity and с825т Polymorphism of gnb3 Gene in Patients with Essential Hypertension </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aleksandr%20Nagay">Aleksandr Nagay</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulnoz%20Khamidullayeva"> Gulnoz Khamidullayeva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is known that an unbalanced intake of salt (NaCI), lifestyle and genetic predisposition to pathology is a key component of the risk and the development of essential hypertension (EH). Purpose: To study the relationship between salt-sensitivity and blood pressure (BP) on systolic (SBP) and diastolic (DBP) blood pressure, depending on the C825T polymorphism of GNB3 in individuals of Uzbek nationality with EH. Method: studied 148 healthy and 148 patients with EH with I-II degree (WHO/ISH, 2003) with disease duration 6,5±1,3 years. Investigation of the gene GNB3 was produced by PCR-RFLP method. Determination of salt-sensitivity was performed by the method of R. Henkin. Results: For a comparative analysis of BP, the groups with carriage of CТ and TT genotypes were combined. The analysis showed that carriers of CC genotype and low salt-sensitivity were determined by higher levels of SBP compared with carriers of CT and TT genotypes, and low salt-sensitivity of SBP: 166,2±4,3 against 158,2±9,1 mm Hg (p=0,000). A similar analysis on the values of DBP also showed significantly higher values of blood pressure in carriers of CC genotype DBP: 105,8±10,6 vs. 100,5±7,2 mm Hg, respectively (p=0,001). The average values of SBP and DBP in groups with carriers of CC genotype at medium or high salt-sensitivity in comparison with carriers of CT or TT genotype did not differ statistically SBP: 165,0±0,1 vs. 160,0±8,6 mm Hg (p=0,275) and DBP: 100,1±0,1 vs. 101,6±7,6 mm Hg (p=0,687), respectively. Conclusion: It is revealed that in patients with EH CC genotype of the gene GNB3 given salt-sensitivity has a negative effect on blood pressure profile. Since patients with EH with the CC genotype of GNB3 gene with low-salt taste sensitivity is determined by a higher level of blood pressure, both on SBP and DBP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salt%20sensitivity" title="salt sensitivity">salt sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20hypertension%20EH" title=" essential hypertension EH"> essential hypertension EH</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20pressure%20BP" title=" blood pressure BP"> blood pressure BP</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20predisposition" title=" genetic predisposition"> genetic predisposition</a> </p> <a href="https://publications.waset.org/abstracts/59953/relationship-salt-sensitivity-and-s825t-polymorphism-of-gnb3-gene-in-patients-with-essential-hypertension" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59953.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">276</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">1143</span> Recent Advancements and Future Trends in the Development of Antimicrobial Edible Films for Food Preservation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raana%20Babadi%20Fathipour">Raana Babadi Fathipour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food packaging plays a crucial role in protecting food from unwanted external factors. Antibacterial edible films are a promising option for food packaging due to their biodegradability, environmental friendliness, and safety. This paper reviews recent research progress on antimicrobial edible films, focusing on those made from polysaccharides, proteins, and lipids. Polysaccharides and proteins are the primary components of antimicrobial edible films, while lipids primarily serve as plasticizers and carriers for active substances in composite films. For instance, second-generation liposomes have shown great potential as carriers for antimicrobial substances and other bioactive compounds due to their exceptional stability. Furthermore, this paper analyzes recent advancements and future trends in antimicrobial edible films. One promising direction is the integration of antimicrobial edible film materials with delivery systems, such as nanoemulsion and microencapsulation technologies, to ensure stable loading of bioactive substances. Another emerging area of interest is the development of smart and active packaging that allows consumers to assess the freshness of food products without opening the package. pH-sensitive films and smart fluorescent "on-off" sensors for humidity are currently being explored as materials for smart and active packaging to monitor food product freshness, with further exploration anticipated in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20edible%20film" title="antimicrobial edible film">antimicrobial edible film</a>, <a href="https://publications.waset.org/abstracts/search?q=biopolymer" title=" biopolymer"> biopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20agent" title=" antimicrobial agent"> antimicrobial agent</a>, <a href="https://publications.waset.org/abstracts/search?q=encapsulation" title=" encapsulation"> encapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20assay" title=" antimicrobial assay"> antimicrobial assay</a> </p> <a href="https://publications.waset.org/abstracts/176779/recent-advancements-and-future-trends-in-the-development-of-antimicrobial-edible-films-for-food-preservation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176779.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">58</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">1142</span> A Hybrid Algorithm for Collaborative Transportation Planning among Carriers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elham%20Jelodari%20Mamaghani">Elham Jelodari Mamaghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Prins"> Christian Prins</a>, <a href="https://publications.waset.org/abstracts/search?q=Haoxun%20Chen"> Haoxun Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, there is concentration on collaborative transportation planning (CTP) among multiple carriers with pickup and delivery requests and time windows. This problem is a vehicle routing problem with constraints from standard vehicle routing problems and new constraints from a real-world application. In the problem, each carrier has a finite number of vehicles, and each request is a pickup and delivery request with time window. Moreover, each carrier has reserved requests, which must be served by itself, whereas its exchangeable requests can be outsourced to and served by other carriers. This collaboration among carriers can help them to reduce total transportation costs. A mixed integer programming model is proposed to the problem. To solve the model, a hybrid algorithm that combines Genetic Algorithm and Simulated Annealing (GASA) is proposed. This algorithm takes advantages of GASA at the same time. After tuning the parameters of the algorithm with the Taguchi method, the experiments are conducted and experimental results are provided for the hybrid algorithm. The results are compared with those obtained by a commercial solver. The comparison indicates that the GASA significantly outperforms the commercial solver. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=centralized%20collaborative%20transportation" title="centralized collaborative transportation">centralized collaborative transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=collaborative%20transportation%20with%20pickup%20and%20delivery" title=" collaborative transportation with pickup and delivery"> collaborative transportation with pickup and delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=collaborative%20transportation%20with%20time%20windows" title=" collaborative transportation with time windows"> collaborative transportation with time windows</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20algorithm%20of%20GA%20and%20SA" title=" hybrid algorithm of GA and SA"> hybrid algorithm of GA and SA</a> </p> <a href="https://publications.waset.org/abstracts/81528/a-hybrid-algorithm-for-collaborative-transportation-planning-among-carriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81528.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">392</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">1141</span> Excitation Density and Energy Dependent Relaxation Dynamics of Charge Carriers in Large Area 2D TMDCs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashish%20Soni">Ashish Soni</a>, <a href="https://publications.waset.org/abstracts/search?q=Suman%20Kalyan%20Pal"> Suman Kalyan Pal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transition metal dichalcogenides (TMDCs) are an emerging paradigm for the generation of advanced materials which are capable of utilizing in future device applications. In recent years TMDCs have attracted researchers for their unique band structure in monolayers. Large-area monolayers could become the most appropriate candidate for flexible and thin optoelectronic devices. For this purpose, it is crucial to understand the generation and transport of charge carriers in low dimensions. A deep understanding of photo-generated hot charges and trapped charges is essential to improve the performance of optoelectronic devices. Carrier trapping by the defect states that are introduced during the growth process of the monolayer could influence the dynamical behaviour of charge carriers. Herein, we investigated some aspects of the ultrafast evolution of the initially generated hot carriers and trapped charges in large-area monolayer WS₂ by measuring transient absorption at energies above and below the band gap energy. Our excitation density and energy-dependent measurements reveal the trapping of the initially generated charge carrier. Our results could be beneficial for the development of TMDC-based optoelectronic devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transient%20absorption" title="transient absorption">transient absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=optoelectronics" title=" optoelectronics"> optoelectronics</a>, <a href="https://publications.waset.org/abstracts/search?q=2D%20materials" title=" 2D materials"> 2D materials</a>, <a href="https://publications.waset.org/abstracts/search?q=TMDCs" title=" TMDCs"> TMDCs</a>, <a href="https://publications.waset.org/abstracts/search?q=exciton" title=" exciton"> exciton</a> </p> <a href="https://publications.waset.org/abstracts/146122/excitation-density-and-energy-dependent-relaxation-dynamics-of-charge-carriers-in-large-area-2d-tmdcs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146122.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">68</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">1140</span> Model for Introducing Products to New Customers through Decision Tree Using Algorithm C4.5 (J-48)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Komol%20Phaisarn">Komol Phaisarn</a>, <a href="https://publications.waset.org/abstracts/search?q=Anuphan%20Suttimarn"> Anuphan Suttimarn</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitchanan%20Keawtong"> Vitchanan Keawtong</a>, <a href="https://publications.waset.org/abstracts/search?q=Kittisak%20Thongyoun"> Kittisak Thongyoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaiyos%20Jamsawang"> Chaiyos Jamsawang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article is intended to analyze insurance information which contains information on the customer decision when purchasing life insurance pay package.

The concept of VCY is based on container interchange between shipping lines. Although this mechanism has been theoretically accepted by the shipping community as a feasible solution, it has not yet achieved the necessary momentum among container shipping lines (CSL). This paper investigates whether there is any legal influence on this industry myopia about the VCY. It is believed that this is the first publication that focuses on the legal aspects of container exchange between carriers. Not much literature on this subject is available. This study establishes with statistical evidence that there is a phobia prevailing in the shipping industry that exchanging containers with other carriers may lead to various legal implications. The complexity of exchange is two faceted. CSLs assume that offering a container to another carrier (obviously, a competitor in terms of commercial context) or using a container offered by another carrier may lead to undue legal implications. This research reveals that this fear is reflected through four types of perceived components, namely: shipping associate; warehouse associate; network associate; and trading associate. These components carry eighteen subcomponents that comprehensively cover the entire process of a container shipment. The statistical explanation has been supported through regression analysis; INCO terms were used to illustrate the shipping process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20container%20yard" title="virtual container yard">virtual container yard</a>, <a href="https://publications.waset.org/abstracts/search?q=legal" title=" legal"> legal</a>, <a href="https://publications.waset.org/abstracts/search?q=maritime%20law" title=" maritime law"> maritime law</a>, <a href="https://publications.waset.org/abstracts/search?q=inventory" title=" inventory"> inventory</a> </p> <a href="https://publications.waset.org/abstracts/111772/virtual-container-yard-assessing-the-perceived-impact-of-legal-implications-to-container-carriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111772.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">165</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">1137</span> Separation of Copper(II) and Iron(III) by Solvent Extraction and Membrane Processes with Ionic Liquids as Carriers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beata%20Pospiech">Beata Pospiech</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Separation of metal ions from aqueous solutions is important as well as difficult process in hydrometallurgical technology. This process is necessary for obtaining of clean metals. Solvent extraction and membrane processes are well known as separation methods. Recently, ionic liquids (ILs) are very often applied and studied as extractants and carriers of metal ions from aqueous solutions due to their good extractability properties for various metals. This work discusses a method to separate copper(II) and iron(III) from hydrochloric acid solutions by solvent extraction and transport across polymer inclusion membranes (PIM) with the selected ionic liquids as extractants/ion carriers. Cyphos IL 101 (trihexyl(tetradecyl)phosphonium chloride), Cyphos IL 104 (trihexyl(tetradecyl)phosphonium bis(2,4,4 trimethylpentyl)phosphi-nate), trioctylmethylammonium thiosalicylate [A336][TS] and trihexyl(tetradecyl)phosphonium thiosalicylate [PR4][TS] were used for the investigations. Effect of different parameters such as hydrochloric acid concentration in aqueous phase on iron(III) and copper(II) extraction has been investigated. Cellulose triacetate membranes with the selected ionic liquids as carriers have been prepared and applied for transport of iron(IIII) and copper(II) from hydrochloric acid solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=copper" title="copper">copper</a>, <a href="https://publications.waset.org/abstracts/search?q=iron" title=" iron"> iron</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquids" title=" ionic liquids"> ionic liquids</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction" title=" solvent extraction"> solvent extraction</a> </p> <a href="https://publications.waset.org/abstracts/58770/separation-of-copperii-and-ironiii-by-solvent-extraction-and-membrane-processes-with-ionic-liquids-as-carriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58770.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">279</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">1136</span> Food Package Design To Preserve The Food Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sugiono">Sugiono</a>, <a href="https://publications.waset.org/abstracts/search?q=Wuwus%20Ardiatna">Wuwus Ardiatna</a>, <a href="https://publications.waset.org/abstracts/search?q=Himma%20Firdaus">Himma Firdaus</a>, <a href="https://publications.waset.org/abstracts/search?q=Nanang%20Kusnandar">Nanang Kusnandar</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayu%20Utomo">Bayu Utomo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimmy%20Abdel%20Kadar">Jimmy Abdel Kadar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was aimed to explore the best design of single-used hot food packaging through various package designs.

This study revealed a significant finding that the transparent plastic box with thin film aluminum foil is the best package. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot%20food" title="hot food">hot food</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20food" title="local food">local food</a>, <a href="https://publications.waset.org/abstracts/search?q=one%20used" title="one used">one used</a>, <a href="https://publications.waset.org/abstracts/search?q=packaging" title="packaging">packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum%20foil" title="aluminum foil">aluminum foil</a> </p> <a href="https://publications.waset.org/abstracts/144647/food-package-design-to-preserve-the-food-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144647.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">149</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">1135</span> Risk Assessment for Aerial Package Delivery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haluk%20Eren">Haluk Eren</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%9Cmit%20%C3%87elik"> Ümit Çelik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent developments in unmanned aerial vehicles (UAVs) have begun to attract intense interest. UAVs started to use for many different applications from military to civilian use. Some online retailer and logistics companies are testing the UAV delivery. UAVs have great potentials to reduce cost and time of deliveries and responding to emergencies in a short time. Despite these great positive sides, just a few works have been done for routing of UAVs for package deliveries. As known, transportation of goods from one place to another may have many hazards on delivery route due to falling hazards that can be exemplified as ground objects or air obstacles. This situation refers to wide-range insurance concept. For this reason, deliveries that are made with drones get into the scope of shipping insurance. On the other hand, air traffic was taken into account in the absence of unmanned aerial vehicle. But now, it has been a reality for aerial fields. In this study, the main goal is to conduct risk analysis of package delivery services using drone, based on delivery routes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerial%20package%20delivery" title="aerial package delivery">aerial package delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=insurance%20estimation" title=" insurance estimation"> insurance estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=territory%20risk%20map" title=" territory risk map"> territory risk map</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicle" title=" unmanned aerial vehicle"> unmanned aerial vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=route%20risk%20estimation" title=" route risk estimation"> route risk estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=drone%20risk%20assessment" title=" drone risk assessment"> drone risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=drone%20package%20delivery" title=" drone package delivery"> drone package delivery</a> </p> <a href="https://publications.waset.org/abstracts/75960/risk-assessment-for-aerial-package-delivery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75960.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">341</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">1134</span> The Investigation of the Impact of Process and Location Parameters in Warpage Study of Semiconductor Packages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wheyming%20Song">Wheyming Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Ssu-Ping%20Lin"> Ssu-Ping Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The primary advantage of package-on-package (PoP) packaging is that since it has less volume, it weighs less. But this is also related to its principal drawback, which is warpage. This research investigates how PoP package warpage patterns are affected by assembling process parameters, including substrate temperature, injection speed, injection temperature, and compound forces. We also investigate how warpage patterns are affected by the location of the silicon chip. The methodologies used in this research are design of experiment and warpage simulation via ANSYS. We propose a regression model to predict the warpage value as a function of substrate temperature, injection speed, injection temperature, and compound forces. Our results show that interaction effects exist between substrate temperature and compound forces and between injection speed and injection temperature. Therefore, determining the optimal values for substrate temperature, compound forces, injection speed, and injection temperature cannot be done individually. Also, our results show that the warpage patterns based on the location of silicon chips can be classified into 11 groups, with the largest warpage occurring at the left-most and right-most sides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=package-on-package" title="package-on-package">package-on-package</a>, <a href="https://publications.waset.org/abstracts/search?q=warpage" title=" warpage"> warpage</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment" title=" design of experiment"> design of experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/70571/the-investigation-of-the-impact-of-process-and-location-parameters-in-warpage-study-of-semiconductor-packages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70571.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">306</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">1133</span> Influence of Recombination of Free and Trapped Charge Carriers on the Efficiency of Conventional and Inverted Organic Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hooman%20Mehdizadeh%20Rad">Hooman Mehdizadeh Rad</a>, <a href="https://publications.waset.org/abstracts/search?q=Jai%20Singh"> Jai Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organic solar cells (OSCs) have been actively investigated in the last two decades due to their several merits such as simple fabrication process, low-cost manufacturing, and lightweight. In this paper, using the optical transfer matrix method (OTMM) and solving the drift-diffusion equations processes of recombination are studied in inverted and conventional bulk heterojunction (BHJ) OSCs. Two types of recombination processes are investigated: 1) recombination of free charge carriers using the Langevin theory and 2) of trapped charge carriers in the tail states with exponential energy distribution. These recombination processes are incorporated in simulating the current- voltage characteristics of both conventional and inverted BHJ OSCs. The results of this simulation produces a higher power conversion efficiency in the inverted structure in comparison with conventional structure, which agrees well with the experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conventional%20organic%20solar%20cells" title="conventional organic solar cells">conventional organic solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=exponential%20tail%20state%20recombination" title=" exponential tail state recombination"> exponential tail state recombination</a>, <a href="https://publications.waset.org/abstracts/search?q=inverted%20organic%20solar%20cells" title=" inverted organic solar cells"> inverted organic solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=Langevin%20recombination" title=" Langevin recombination"> Langevin recombination</a> </p> <a href="https://publications.waset.org/abstracts/79569/influence-of-recombination-of-free-and-trapped-charge-carriers-on-the-efficiency-of-conventional-and-inverted-organic-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79569.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">185</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">1132</span> Static Analysis of Security Issues of the Python Packages Ecosystem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Gorine">Adam Gorine</a>, <a href="https://publications.waset.org/abstracts/search?q=Faten%20Spondon"> Faten Spondon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Python is considered the most popular programming language and offers its own ecosystem for archiving and maintaining open-source software packages. This system is called the python package index (PyPI), the repository of this programming language. Unfortunately, one-third of these software packages have vulnerabilities that allow attackers to execute code automatically when a vulnerable or malicious package is installed. This paper contributes to large-scale empirical studies investigating security issues in the python ecosystem by evaluating package vulnerabilities. These provide a series of implications that can help the security of software ecosystems by improving the process of discovering, fixing, and managing package vulnerabilities. The vulnerable dataset is generated using the NVD, the national vulnerability database, and the Snyk vulnerability dataset. In addition, we evaluated 807 vulnerability reports in the NVD and 3900 publicly known security vulnerabilities in Python Package Manager (pip) from the Snyk database from 2002 to 2022. As a result, many Python vulnerabilities appear in high severity, followed by medium severity. The most problematic areas have been improper input validation and denial of service attacks. A hybrid scanning tool that combines the three scanners bandit, snyk and dlint, which provide a clear report of the code vulnerability, is also described. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Python%20vulnerabilities" title="Python vulnerabilities">Python vulnerabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=bandit" title=" bandit"> bandit</a>, <a href="https://publications.waset.org/abstracts/search?q=Snyk" title=" Snyk"> Snyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Dlint" title=" Dlint"> Dlint</a>, <a href="https://publications.waset.org/abstracts/search?q=Python%20package%20index" title=" Python package index"> Python package index</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem" title=" ecosystem"> ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20analysis" title=" static analysis"> static analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=malicious%20attacks" title=" malicious attacks"> malicious attacks</a> </p> <a href="https://publications.waset.org/abstracts/161094/static-analysis-of-security-issues-of-the-python-packages-ecosystem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161094.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">139</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">1131</span> The Advertising Channels Affecting to Consumer Purchasing Decisions: Case Study of Hair-Care Market in Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narong%20Anurak">Narong Anurak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to find out the hair-care purchasing behavior at hypermarkets and to investigate two factors, package design and advertising channels, that influenced hair-care purchasing behavior.

The most effective way of achieving this goal is to be able to penetrate strategic targets. Strategic targets are generally located deep inside of the countries and are defended by modern and efficient surface to air missiles (SAM) platforms which are operated as integrated with Intelligence, Surveillance and Reconnaissance (ISR) systems. On the other hand, these high valued targets are buried deep underground and hardened with strong materials against attacks. Therefore, to penetrate these targets requires very detailed intelligence. This intelligence process should include a wide range that is from weaponry to threat assessment. Accordingly, the framework of the attack package will be determined. This mission package has to execute missions in a high threat environment. The way to minimize the risk which depends on loss of life is to use packages which are formed by UAVs. However, some limitations arising from the characteristics of UAVs restricts the performance of the mission package consisted of UAVs. So, the mission package should be formed with UAVs under the leadership of a fifth generation manned aircraft. Thus, we can minimize the limitations, easily penetrate in the deep inside of the enemy territory with minimum risk, make a decision according to ever-changing conditions and finally destroy the strategic targets. In this article, the strengthens and weakness aspects of UAVs are examined by SWOT analysis. And also, it revealed features of a mission package and presented as an example what kind of a mission package we should form in order to get marginal benefit and penetrate into strategic targets with the development of autonomous mission execution capability in the near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UAV" title="UAV">UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomy" title=" autonomy"> autonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=mission%20package" title=" mission package"> mission package</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20attack" title=" strategic attack"> strategic attack</a>, <a href="https://publications.waset.org/abstracts/search?q=mission%20planning" title=" mission planning"> mission planning</a> </p> <a href="https://publications.waset.org/abstracts/10355/evaluating-the-use-of-manned-and-unmanned-aerial-vehicles-in-strategic-offensive-tasks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10355.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">550</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">1129</span> Hot Carrier Photocurrent as a Candidate for an Intrinsic Loss in a Single Junction Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Gradauskas">Jonas Gradauskas</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleksandr%20Masalskyi"> Oleksandr Masalskyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ihor%20Zharchenko"> Ihor Zharchenko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The advancement in improving the efficiency of conventional solar cells toward the Shockley-Queisser limit seems to be slowing down or reaching a point of saturation. The challenges hindering the reduction of this efficiency gap can be categorized into extrinsic and intrinsic losses, with the former being theoretically avoidable. Among the five intrinsic losses, two — the below-Eg loss (resulting from non-absorption of photons with energy below the semiconductor bandgap) and thermalization loss —contribute to approximately 55% of the overall lost fraction of solar radiation at energy bandgap values corresponding to silicon and gallium arsenide. Efforts to minimize the disparity between theoretically predicted and experimentally achieved efficiencies in solar cells necessitate the integration of innovative physical concepts. Hot carriers (HC) present a contemporary approach to addressing this challenge. The significance of hot carriers in photovoltaics is not fully understood. Although their excessive energy is thought to indirectly impact a cell's performance through thermalization loss — where the excess energy heats the lattice, leading to efficiency loss — evidence suggests the presence of hot carriers in solar cells. Despite their exceptionally brief lifespan, tangible benefits arise from their existence. The study highlights direct experimental evidence of hot carrier effect induced by both below- and above-bandgap radiation in a singlejunction solar cell. Photocurrent flowing across silicon and GaAs p-n junctions is analyzed. The photoresponse consists, on the whole, of three components caused by electron-hole pair generation, hot carriers, and lattice heating. The last two components counteract the conventional electron-hole generation-caused current required for successful solar cell operation. Also, a model of the temperature coefficient of the voltage change of the current–voltage characteristic is used to obtain the hot carrier temperature. The distribution of cold and hot carriers is analyzed with regard to the potential barrier height of the p-n junction. These discoveries contribute to a better understanding of hot carrier phenomena in photovoltaic devices and are likely to prompt a reevaluation of intrinsic losses in solar cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20cell" title="solar cell">solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20carriers" title=" hot carriers"> hot carriers</a>, <a href="https://publications.waset.org/abstracts/search?q=intrinsic%20losses" title=" intrinsic losses"> intrinsic losses</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=photocurrent" title=" photocurrent"> photocurrent</a> </p> <a href="https://publications.waset.org/abstracts/182014/hot-carrier-photocurrent-as-a-candidate-for-an-intrinsic-loss-in-a-single-junction-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182014.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">65</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">1128</span> TDApplied: An R Package for Machine Learning and Inference with Persistence Diagrams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shael%20Brown">Shael Brown</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Farivar"> Reza Farivar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Persistence diagrams capture valuable topological features of datasets that other methods cannot uncover.

In comparison to other non-destructive techniques such as x-ray inspection method, scanning acoustic tomograph (SAT) and microwave inspection method, THz-TDS imaging method has many advantages: First, it can measure the exact thickness and location of defects. Second, it doesn’t require the liquid couplant while it is very crucial to deliver that power of ultrasonic wave in SAT method. Third, it didn’t damage to materials and be harmful to human bodies while x-ray inspection method does. Finally, it exhibits better spatial resolution than microwave inspection method. However, this technology couldn’t be applied to IC package because THz radiation can penetrate through a wide variety of materials including polymers and ceramics except of metals. Therefore, it is difficult to detect the defects in IC package which are composed of not only epoxy and semiconductor materials but also various metals such as copper, aluminum and gold. In this work, we proposed a special method for detecting the void in the IC package using THz-TDS imaging system. The IC package specimens for this study are prepared by Packaging Engineering Team in Samsung Electronics. Our THz-TDS imaging system has a special reflection mode called pitch-catch mode which can change the incidence angle in the reflection mode from 10 o to 70 o while the others have transmission and the normal reflection mode or the reflection mode fixed at certain angle. Therefore, to find the voids in the IC package, we investigated the appropriate angle as changing the incidence angle of THz wave emitter and detector. As the results, the voids in the IC packages were successfully detected using our THz-TDS imaging system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=terahertz" title="terahertz">terahertz</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20technique" title=" non-destructive technique"> non-destructive technique</a>, <a href="https://publications.waset.org/abstracts/search?q=void" title=" void"> void</a>, <a href="https://publications.waset.org/abstracts/search?q=IC%20package" title=" IC package"> IC package</a> </p> <a href="https://publications.waset.org/abstracts/20518/non-destructive-technique-for-detection-of-voids-in-the-ic-package-using-terahertz-time-domain-spectrometer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20518.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">473</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">1126</span> Improving Physicochemical Properties of Milk Powder and Lactose-Free Milk Powder with the Prebiotic Carrier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chanunya%20Fahwan">Chanunya Fahwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Supat%20Chaiyakul"> Supat Chaiyakul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A lactose-free diet is imperative for those with lactose intolerance and experiencing milk intolerance.

CB, RMD, and PDX are three possible carriers, which are applied to both regular cow's milk formula and lactose-free cow milk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lactose-free%20milk%20powder" title="lactose-free milk powder">lactose-free milk powder</a>, <a href="https://publications.waset.org/abstracts/search?q=prebiotic%20carrier" title=" prebiotic carrier"> prebiotic carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=co-particle" title=" co-particle"> co-particle</a>, <a href="https://publications.waset.org/abstracts/search?q=glycemic%20index" title=" glycemic index"> glycemic index</a> </p> <a href="https://publications.waset.org/abstracts/181574/improving-physicochemical-properties-of-milk-powder-and-lactose-free-milk-powder-with-the-prebiotic-carrier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181574.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">81</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">1125</span> Learning Based on Computer Science Unplugged in Computer Science Education: Design, Development, and Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eiko%20Takaoka">Eiko Takaoka</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshiyuki%20Fukushima"> Yoshiyuki Fukushima</a>, <a href="https://publications.waset.org/abstracts/search?q=Koichiro%20Hirose"> Koichiro Hirose</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadashi%20Hasegawa"> Tadashi Hasegawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although all high school students in Japan are required to learn informatics, many of them do not learn this topic sufficiently. In response to this situation, we propose a support package for high school informatics classes. To examine what students learned and if they sufficiently understood the context of the lessons, a questionnaire survey was distributed to 186 students. We analyzed the results of the questionnaire and determined the weakest units, which were “basic computer configuration” and “memory and secondary storage”. We then developed a package for teaching these units. We propose that our package be applied in high school classrooms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20science%20unplugged" title="computer science unplugged">computer science unplugged</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20science%20outreach" title=" computer science outreach"> computer science outreach</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20school%20curriculum" title=" high school curriculum"> high school curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20evaluation" title=" experimental evaluation"> experimental evaluation</a> </p> <a href="https://publications.waset.org/abstracts/6381/learning-based-on-computer-science-unplugged-in-computer-science-education-design-development-and-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6381.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">387</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">1124</span> Effects of Computer Aided Instructional Package on Performance and Retention of Genetic Concepts amongst Secondary School Students in Niger State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20R.%20Bello">Muhammad R.

Quasi-experimental research design i.e. pre-test-post-test experimental and control groups were adopted for the study. The population of the study was all senior secondary school three (SS3) students’ offering biology. A sample of 223 students was randomly drawn from six purposively selected secondary schools. The researchers’ developed computer aided instructional package (CAIP) on genetic concepts was used as treatment instrument for the experimental group while the control group was exposed to the conventional lecture method (CLM). The instrument for data collection was a Genetic Performance Test (GEPET) that had 50 multiple-choice questions which were validated by science educators. A Reliability coefficient of 0.92 was obtained for GEPET using Pearson Product Moment Correlation (PPMC). The data collected were analyzed using IBM SPSS Version 20 package for computation of Means, Standard deviation, t-test, and analysis of covariance (ANCOVA). The ANOVA analysis (Fcal (220) = 27.147, P < 0.05) shows that students who received instruction with CAIP outperformed the students who received instruction with CLM and also had higher retention. The findings also revealed no significant difference in performance and retention between male and female students (tcal (103) = -1.429, P > 0.05). It was recommended amongst others that teachers should use computer-aided instructional package in teaching genetic concepts in order to improve students’ performance and retention in biology subject.
