Adding UX in the Service Design Loop: The Case of Crisis Management Services
Authors: Touloum Karim , Idoughi Djilali , Seffah Ahmed
Published: March 2022

Focus on user experience (UX) has been a growing trend in service design (SD), as it has various benefits. As it will be demonstrated in this paper, developing an efficient, yet usable crisis management service requires a deep understanding of the experience of all stakeholders involved in the crisis. While many SD studies have proposed different principles, practices and tools, there is a lack of a practical comprehensive design framework that empowers designers to integrate effectively UX in the SD lifecycle. In this paper we propose a methodological framework called UXD-IS (User eXperience Design of Interactions and Services) that combines UX characterization and touchpoints analysis. The framework has been validated through a case study related to flooding crisis management. The investigations reveal that the framework is a powerful support tool during the first phases of the development of a new service or the improvement of an existing one.

This paper illustrates the research and development work done in the last 4 years in the frame of rescue operations of migrants who attempt to reach Italian coasts via sea journeys on Mediterranean routes. The context, characterized by humanitarian, social, and organizational issues, presents complex challenges that can only be tackled with a multidisciplinary, participatory, and internationalized approach. The ITHEALTH system and the results of its usability and user experience evaluations are presented. It takes inspiration from other projects developed for different purposes but acting in similar context and according to similar socio-technical dimensions.
Digitalisation and the UN Sustainable development Goals: What role for design
Authors: van der Velden Maja
Published: March 2022

This paper investigates the relation between digitalisation and the Sustainable Development Goals (SDGs). Digitalisation is often presented as a transformative power, changing the way we live and work. The SDGs describe digitalisation technologies such as ICTs as enablers of sustainable development. The unsustainability of these technologies themselves may actually undermine the gains made in digitalisation. This becomes clear when we locate the discussion of digitalisation and the SDGs in a discussion of the Planetary Boundaries framework. The example of one of the most emblematic digital technologies of our time, the smartphone, shows the negative impact of its production and consumption on the biosphere, the basis for all life on our planet, and on many of the social aspects of the SDGs, such as poverty, child labour, decent work, and peace. But rather than promoting sustainable digitalisation, this paper proposes the notion of sustainment as a foundational principle for the sustainability of digitalisation. While sustainability has become a mean to an end, sustainment is about sustaining life itself. With sustainment, digitalisation and its design can strengthen our ability to respond to the challenges of living on a finite planet.

Published: March 2022

This study explored the effects of adding visual continuous feedback in the form of feedback bars to a teachable-agent based learning game in mathematics. 45 8-12-years-old from three Swedish school classes used the game during four math lessons. The focus was on how feedback to the students regarding their teachable agents learning progression – and different detailedness of such feedback – affects how the students (in a teacher role) experience the learning game. The results suggest that students were positive towards receiving immediate and continuous feedback, but their preferences with respect to the detailedness of the feedback differed according to their age. We found a divergence as to the preferred number of bars, where the 3rdand 5thgraders preferred 1 or 3 bars but where the 2ndgraders preferred the more detailed version (6 bars) despite their lack of understanding of what the different bars represented.

Waiting to get a service is something that we often see or experience in everyday life. The phenomenon is referred to as a queue, where the stage of the series of queuing phenomena starts from the arrival of customers, waiting to be served (the server is busy) and leaving the queue when when they have received service. This queue occurs because the arrival rate is faster than the available service rate. This causes less than the maximum service provided to customers. The place of research in this study is at the Cigudeg Public Health Center, Bogor, West Java, with the time of the study being carried out on March 25, 2021 – April 23, 2021. The object in this study is the prescription queue that occurs at the medicine collection counter. As for the purpose of this study is to find alternative solution is by using the queuing theory analysis method. As for the result of this study, it can be concluded that the queuing system used by the Cigudeg Public Health Center is a single channel single phase with a queuing model ( M/M/1 ) : (GD//), which means that there is only 1 server at the counter. Therefore, there are still frequent queues of prescriptions at the counter. After analysis and calculation using the queuing method, a queuing model ( M/M/2 ) : (GD//) is obtained where the optimum number of servers obtained is 2 servers.

Method of Compact Ground Launching Devices Shape Formation for Unmanned Aerial Vehicles
Authors: SEREDA Vladyslav A. , AMBROZHEVICH Maya V. , KORNEV Aleksey V.
Published: March 2022

The purpose of this paper is to develop a method for forming the shape of compact ground launching devices (GLDs) unmanned aerial vehicles (UAVs), which includes three stages. Firstly, the choice on the basis of the theory of dimension and similarity of the closest analogue of the design object based on world experience gained in this field. Secondly, the creation of a comprehensive model of the working process of GLD and a universal method for its numerical implementation. Thirdly, the solution to the problem of optimizing the dynamic characteristics of GLD. At the described stages of the formation of the shape of an GLD UAV, a statistical analysis of the technical perfection of known analogues of UAV launch systems, methods of the theory of similarity and dimension in mechanics, methods of numerical simulation of the working process, and also methods of conditional parametric optimization are used. The undoubted importance of the problem of the equivalent development of the components of the UAS, consisting of an aircraft and a launch system (catapult). The traditionally non-priority status of GLD in the general cycle of the complex design program is also known. A systematic solution to this problem lies in the mainstream of creating common approaches, one of which is contained in this article. The proposed method of forming the appearance of compact GLDs UAV can be extended to a wide class of starting systems containing a thermal expansion machine and a mechanical component. In the presented form, the method is not applicable to systems of air, aerodrome and manual launch of UAVs. A method has been developed for the formation of the shape of GLD based on the energy relations of the criterion type between useful functions and the corresponding costs, with subsequent verification numerical studies of the launch processes based on specially created technology of a computational experiment, as well as optimization of the dynamic characteristics of GLD. The method of forming the shape of compact GLD is universally applicable to any type of catapults, regardless of the type of transmission and drive, since many particular forms of organization of the working process are generalized using the criteria of energy perfection, a comprehensive physical and mathematical model and normalization of the starting overload.

Authors: FRANT Michał , WRZESIEŃ Stanisław , MAJCHER Maciej
Published: March 2022

This study provides the results of experimental tests of the effect of floats on the aerodynamic characteristics of the “OSA” plane in an asymmetric flow. The tests were carried out in a low-speed wind tunnel owned by Institute of Aviation Technology, Faculty of Mechatronics, Armament and Aerospace (FMAA), Military University of Technology (MUT, Warsaw, Poland).. The model of “OSA” was tested at dynamic pressure q = 500 Pa within the range of slip angles β = -2828. The tests were carried out for the plane model in the so-called “plain” configuration, i.e. at non-deflected control surfaces and wing mechanisation elements. The model was tested in two variants – with floats and without floats. The effect of deflection of the flaps, ailerons and rudder on the aerodynamic characteristics of the test model was also examined. The obtained values of drag coefficient, lateral force coefficient and yawing moment coefficient are presented in the form of tables and graphs. The tests showed that the floats had a significant impact on the curves of the characteristics. They result in a considerable increase of the value of the drag coefficient and in a deterioration of weathercock stability.

A Two-Step Unsupervised Learning Approach to Diagnose Machine Fault Using Big Data
Authors: Sharmila V. J. , Florinabel D. Jemi
Published: March 2022

The modern industrial sector requires an intelligent fault diagnosis system to ensure reliable and safe processingsince traditional methods require expert diagnosis, which consumes time and requires labor. Furthermore, diagnosticresults are influenced by the expert’s expertise and in-depth knowledge of the machine. The objective of this paper isto solve the manual intervention problem and improve the fault diagnosis. We propose a novel two-stage unsupervisedlearning algorithm based on artificial intelligence (AI) that learns fault features efficiently from raw vibration signals.To accomplish the aforementioned goal, we encapsulate the two-stage learning technique such as sparse filtering andRectified Linear Unit (ReLU) regression function. As a first step, we used a two-layer neural network sparse filteringprocedure to extract vibration signals’ features. Based on vibration signals, ReLU regression determines the healthcondition of the machine in the second phase. ReLU is a linear function that improves the performance of neural network training. Here we utilized a sigmoid and softmax regression function to compare the performance of ReLU. Thesigmoid function works well for binary classification, whereas softmax works well for multiclass classification. A database of motor-bearing vibration signals containing signals about four different health conditions of machines, suchas Inner race faults (IF), Outer race faults (OF), and rolling faults (RF). The sparse filter is evaluated on different inputand output dimensions, which significantly increases the learning accuracy. We classified the health condition usingReLU and achieved 93.8% accuracy, which is higher than sigmoid and softmax. Through the two-step learning process, machine fault diagnosis is enhanced, as well as big data is effectively handled.

Published: March 2022

O Programa de Pesquisas Ecológicas de Longa Duração (PELD) realizou estudos junto às comunidades vizinhas do Parque Estadual do Rio Doce (PERD), no Vale do Aço em Minas Gerais, que resultaram em diversos cenários locais participativos. Entre esses resultados, foi elaborado um modelo espacialmente explícito que apresenta as aptidões das áreas pertencentes ao entorno do parque, para implementação de sistemas agroflorestais (SAF). O modelo foi construído com base no método de análise multicritério AHP (Analytic Hierarchy Process), com apoio de ferramentas de informação geográfica. O resultado apresentou as localizações e os tamanhos das áreas aptas para agroflorestas voltadas para a preservação ambiental e para geração de renda. As variáveis aplicadas foram: a) Índice de Vegetação de Diferença Normalizada (NDVI); b) Áreas de Preservação Permanente (APP); c) Classificação de Uso e Cobertura da Terra; d) proximidade de vias de acesso. As áreas de aptidão mais elevada para os SAF somam 5.580 hectares. Estas apresentam todas as características propícias, de acordo com as variáveis analisadas: fazem parte de áreas rurais antropizadas aquelas próximas às rodovias, dentro de APPs e com baixo índice de vegetação. Entre estas, grande parte são adjacentes ao PERD, principalmente nas zonas rurais de Coronel Fabriciano-MG e Timóteo-MG. As porções mais extensas são localizadas às margens dos rios maiores. Além disso, a partir de uma análise complementar, também foram identificados os perímetros mais aptos para os SAF que não fazem parte de APP. Por sua vez, estas áreas foram encontradas, em sua maioria, dentro das áreas rurais dos municípios de Coronel Fabriciano-MG, Ipatinga-MG e Caratinga-MG. Diante de todos os aspectos analisados, concluiu-se que os modelos gerados podem auxiliar trabalhos de implementação de SAF naquela região, dando suporte inicial para identificação das áreas mais propícias ao plantio.

Published: March 2022

Objetivou-se quantificar os teores de C nos reservatórios da biomassa vegetal de diferentes espécies da Caatinga, floresta tropical seca do Nordeste do Brasil. Foi realizado um estudo florístico e fitossociológico prévio e selecionadas nove espécies de maior densidade absoluta, que representou 87% do fragmento. Foram amostradas biomassa dos compartimentos folhas e lenho de cada uma das espécies para determinação do teor de C. Como resultado, houve diferença nos teores foliares de C entre as espécies. O teor de C foliar das espécies variou entre 448,0 e 454,3 g C por kg de biomassa seca e o teor de C do lenho das espécies variou entre 451,4 e 453,1 g C por kg de biomassa seca. Esses resultados sugerem a utilização de fator de conversão de biomassa para carbono específico por espécie em Caatinga, como alternativa ao fator genérico de 50% recomendado pelo IPCC. Esta pesquisa revela que o uso do fator recomendado pelo IPCC superestima estoques de C em Caatinga. Mais estudos são encorajados para confirmar esse resultado.

Published: March 2022

The number of chromosomes and the meiotic characterization are important to studies involving genetic variability, germplasm and biodiversity. However, native forest species have not been sufficiently analyzed from a cytotaxonomic point of view. Therefore, the number of chromosomes, the meiotic behavior and the pollen viability of the Diatenopteryx sorbifolia Radlk were determined from five different accessions located in the southern region of Brazil. The species was considered diploid, 2n = 30 (x = 15), with regular meiotic behavior in phase I and absent in phase II, suggesting the presence of a genetic abnormality. Pollen grains infertility was between 57 and 67%. which may be associated to the formation of a low number of seeds in Diatenopteryx sorbifolia, probably due to the irregular behavior of the microsporogenesis.

No Brasil, a seringueira Hevea brasiliensis (Willd. ex A.Juss.) é plantada em áreas de escape para evitar a doença do mal-das-folhas. Embora haja relatos de danos ocasionados por insetos e ácaros na literatura, estes são esparsos. O objetivo deste estudo foi realizar um levantamento populacional da comunidade de Scolytinae, Platypodinae (Curculionidae) e Bostrichidae em um plantio de seringueira em Goianésia, estado de Goiás, com armadilhas de impacto de voo iscadas com etanol, de março de 2013 a março de 2014. Scolytinae (13 gêneros, 29 espécies) foi o grupo mais abundante, representando mais de 99% dos espécimes capturados, enquanto que seis espécies de Bostrichidae, sete de Cerambycidae e duas de Platypodinae foram também capturadas. Hypothenemus obscurus (Scolytinae) representou cerca de 89% de todos os exemplares capturados. Embora nenhum ataque a árvores vivas tenha sido observado durante a pesquisa, espécies com capacidade conhecida de atacar e colonizar com sucesso árvores vivas foram capturadas neste estudo. Talvez isso seja uma indicação de que a plantação é bem gerenciada, não fornecendo condições para que isso ocorra.

Recruitment exceeds mortality in subtropical secondary forest after conventional selective logging
Authors: Likoski Janine Kervald , Vibrans Alexander Christian , Silva Daniel Augusto da
Published: March 2022

Studies on the dynamics of managed forests are essential for planning and executing management strategies. Timber harvesting can modify recruitment rates, mortality, gain and loss of basal area of the remaining stand. In secondary forests, especially in the Atlantic Forest, these studies are still scarce. Our study hypothesis is that the management intervention stimulates the growth of the remaining trees, overcoming the reduction of the growth of the damaged trees and the harvest mortality. We investigated the dynamics of the remaining trees and recruits (in number of individuals and basal area), with DBH ≥ 5 cm, by ecological group of the species, and the damage to the remaining adult individuals. We measured eleven permanent plots with 1.600m² each, before and four years after being harvested in a secondary forest in southern Brazil. We found that the different harvesting intensities significantly influence the forest dynamics, special the annual recruitment rates, while basal area gain/loss showed a weaker relationship to logging intensity. However, the mortality rates are similar in control plots and managed plots. We also observed that in the managed plots, the recruitment rate (5.3 ± 1.9% year-¹) exceeded mortality (2.3 ± 1.2% year-¹). Among ecological groups, we found less recruitment of climax species than of secondary species. In general, the proportion of damage of remaining trees decreased over time. We conclude that the management has modified the forest dynamics, indicating that planning, including adequate cutting limits and low impact harvesting methods are essential for achieving the sustainability of forest management.

Sunlight directly influences on the development of forest species by affecting the attributes of plant growth and physiology. Among these species, Erythroxylum pauferrense Plowman is considered a rare species, as its distribution is restricted only to the state of Paraíba. Therefore, studies are needed that seek to evaluate the adaptation, development and propagation of the species under different environmental conditions. This study aimed to evaluate morphophysiological aspects of Erythroxylum pauferrense seedlings submitted to different levels of shading. The experiment was carried out under greenhouse condition in a completely randomized design with five treatments (0, 30, 50, 70, and 90% shading) and eight replicates. Growth characteristics, morphofunctional attributes, gas exchange, chlorophyll (Chl) a fluorescence, and Chl content were evaluated. Data were submitted to analysis of variance followed by polynomial regression analysis. Results showed that plants grown under 30 to 50% shading showed higher plant height, stem diameter, absolute growth rate for plant height, leaf dry mass, stem dry mass, total dry mass, Dickson’s quality index, leaf area, and leaf area index, as well as net assimilation rate of CO2, stomatal conductance, transpiration, instantaneous water use efficiency, and Chl a, b, and a+b contents. Therefore, levels from 30 to 50% shading are the most recommended for the production of Erythroxylum pauferrense seedlings. We recommend using Erythroxylum pauferrense to reforest the understory in disturbed areas in Brejos de Altitude and large-scale production of seedlings under intermediate levels of shading.

Created in 2014, the Serra da Gandarela National Park (SGNP), is repeatedly affected by wildfires. This Conservation Unit is located in the Iron Quadrangle (MG), in a transition zone between the Cerrado and the Atlantic Forest biomes, and is characterized by a complex mosaic of phytophysiognomies. The aim of this investigation was to compare the performance of two risk mapping models for forest fire in the SGNP and its surroundings, based on two different approaches, being one by multicriteria analysis, AHP method and the other a simple probability method, called Hot Spot History, which provided information on the areas of highest and lowest risk and their environmental and human characteristics. Spatial data from remote sensing and GIS were used to simulate, in sequence, the fire ignition, the fire spread and, finally, the risk of wildfire. The validation of the risk models was performed by the Kappa coefficient (K). The results showed that the model based on the History of Hot Points obtained greater accuracy (0.61) than the model generated by the AHP method (0.54). The Brazilian Savanna, Rupestrian Fields and Field coverings were the most susceptible to wildfire, as they are formed by herbaceous vegetations and are located very close to urban agglomerations and roads. The slopes oriented to the North and West were important for the prediction of wildfires slope and, on the other hand, the slope of the terrain was not important to discretize the areas of greater and lesser fragility to the referred ecological disturbance.
“Paul and Mary Would Like You to Bake”
Authors: Kjærulff Caroline
Published: March 2022

In a time of devolution and fragmentation in the UK, The Great British Bake Off plays into the elements of heritage film and imperial nostalgia and especially all things considered ‘English’. However, the show also attempts to include a more diverse representation of the British people and recreate a national identity that leaves more space for ethnic minorities. Linking theories on national identity and theories on heritage film, this article examines how the GBBO format acts as heritage television which idealizes certain aspects of English history, as well as how the inclusion and celebration of contestants with an ethnic minority background adds to a portrayal of an idealized form of British multiculturalism. These findings lay the basis for a discussion on the connection between food culture and multiculturalism, and how GBBO tries to combine the past ‘glory’ of England with the present (multicultural) reality of Britain.

This article examines the moral duality presented in Robert Louis Stevenson’s novella The Strange Case of Dr. Jekyll and Mr. Hyde and its connection to the Christian morals guiding Victorian society. It suggests that the novella undermines a dualistic Christian perception of human nature through changes in point of view and by replacing a clear duality with an abject ambiguity. It argues that in the novella abjection of part of the self is portrayed as destructive and that the novella is essentially a critique of repressive Christian morals.

Subtractive bilingualism is a phenomenon that is common among children of immigrants, and refers to a process in which the acquisition of a second language results in the deterioration of the heritage language. This article is a critical overview of some of the literature surrounding this phenomenon in immigrant families residing in English speaking countries, as well as how it can affect family relationships. It is concluded that heritage language proficiency, as well as the simultaneous mastery of the heritage language and the dominant language, typically leads to improved relationships, while subtractive bilingualism often is associated with intergenerational conflict. However, many immigrant families navigate issues of communication brought about by subtractive bilingualism in a multitude of different ways, thus illustrating that the families do not necessarily become dysfunctional due to linguistic barriers, rather they employ strategies to minimize miscommunication.

This article investigates whether Arctic Monkeys frontman Alex Turner’s use of northern English linguistic features decreased from the band’s first album Whatever People Say I am, That's What I'm Not (WPS) (2006) to their fifth album AM (2013); whether this was because Turner began to accommodate to American audiences instead of British audiences. An auditory analysis of two songs from each album was conducted to see if Turner’s use of glottalisation and th-fronting, typical northern English variants, changed. The results showed a clear decline in Turner’s use of northern English linguistic features between the two albums. The article concludes that British youth was the intended audience in WPS, but it is unclear who the intended audience is in AM as Turner continued to use other non-standard features that index Turner’s British roots.

In urban sustainability researches, benchmarking methods have become the most needed ways to measure urban energy efficiency. Benchmarking the efficiency of urban energy with parametric and non-parametric methods are important cases within the energy field. Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) are ideal approaches to measure performance of various industries with multiple indicators. Stochastic method considers the noise in data and evaluates the critical success parameters of energy efficiency by separating noise from efficiency scores. This study evaluates urban energy efficiency by deterministic and stochastic ways with deploying DEA and SFA methodologies. The aim of the study is to show the effects and results of deterministic and stochastic approaches in urban energy efficiency measurement and to evaluate how Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) can be used to derive measures of efficiency and productivity change over time in complex multi‐output multi‐input contexts in the production and consumption of energy services. Using data gathered from Turkish Statistical Institute (TURKSTAT) and Energy Market Regulatory Authority (EMRA) Development Reports. In the study, 30 cities, which are accepted as metropolitans of Turkey by government, are selected as Decision Making Units (DMUs) of both methods. As a result, different efficiency estimates are presented and evaluated within the scope of statistical noise, multiple inputs and outputs by DEA and SFA methods.

In recent years, it has become more preferable for the products to be used in cosmetics to be of herbal origin. In particular, plants with high antioxidant properties are preferred to be the source for cosmetic products. Endemic plants, which are used only by the local people, will be more profitable economically if they are grown for use in different industries, especially in cosmetics. T.orientalis is an endemic species that grows only in the Black Sea region of Turkey. This study aims to show that these plant extracts have the potential for use in the cosmetic industry. For this purpose, firstly the stem, flower, and leaf parts of T.orientalis were extracted with acetone and their antioxidant activities were measured. According to the results, antioxidant activity was especially high in stem extracts (DPPH 57,12 mg L-ascorbic acid/g; total phenol 288,10 ± 8,55 mg/g dry weight). Then, the antibacterial activity of the extracts on S. aureus was investigated. As a result, no effective activity was found. In addition, SPF values and collagenase, tyrosinase, and elastase inhibiting activities were measured. The best results were observed in the stem (SPF 31,18 ± 0,18%; anti-collagenase 87,25%; anti-tyrosinase 11,47%; anti-elastase 57,64%) and leaf extracts (SPF 31,27 ± 0,24%; anti-collagenase 97,57%; anti-tyrosinase 15,03%; anti-elastase ND). As a result, it has been seen that especially the stem parts of T.orientalis can be used as an ingredient for photoprotective and antiaging purposes in cosmetics.

Çalışan kişiye uyacak şekilde iş, ekipman ve işyeri tasarlama bilimi "ergonomi" olarak adlandırılır. Ergonomi, endüstriyel şirketler tarafından işçilerin görevlerini ve çalışma alanlarını tasarlamak için yaygın olarak kullanılır. Ergonominin amacı, insan-makine etkileşimini geliştirerek sistemlerin performansını artırmaktır. Bu bağlamda kullanıcı arayüzü tasarlanarak, bunun yanısıra ilgili sistemler geliştirilerek görev ve kullanıcı ile daha uyumlu hale getirilebilir. Ergonomi; antropometri, biyomekanik, genel mühendislik, fizyoloji, psikoloji ve fizik gibi çeşitli disiplinleri içerir. Burada değinilmesi gereken önemli konulardan biri; başta boyun, sırt, bilek, kol, omuz ve bacaklar olmak üzere bazı vücut bölgelerinin riske maruz kalma düzeyini belirleyen risk değerlendirmesidir. Olumsuz etkilerini önlemek için risk düzeyini belirlemek önemlidir. Bu amaçla, risk seviyelerini belirlemek için Hızlı Tüm Vücut Değerlendirmesi (REBA), Hızlı Üst Ekstremite Değerlendirmesi (RULA) ve Hızlı Maruziyet Değerlendirme (HMD) gibi çeşitli yöntemler kullanılır. Ancak risk seviyesi sektörlere göre değişmektedir. İnşaat sektörü en riskli sektörlerden biridir ve önemine göre bu çalışmada ele alınmıştır. İnşaat endüstrisindeki bazı yaygın süreçler seçilmiştir ve üç ergonomi risk değerlendirme yöntemi; bir Türk inşaat firmasındaki riskleri ortaya çıkarmak için REBA, RULA ve HMD uygulanmıştır. İlgili sonuçlar karşılaştırmalı olarak sunulmuş ve yorumlanmıştır.

Published: March 2022

Günümüz pazar koşullarında işletmeler lojistik operasyonlarını maliyet ve rekabet avantajı sağlayacak etkin bir stratejiyle sürdürmek zorundadır. Müşterilerden gelen fiyat baskıları ve özellikle politik, ekonomik ve çevresel hassasiyetler gereği, ürün geri dönüşüm süreçleri -yani ürünün geri kazanılarak yeniden değerlendirilmesi- tersine lojistik (TL) uygulamalarını gerektirmektedir. İşletmeler için, TL yönetiminde genellikle özel bilgi sistemlerine sahip bir altyapı ve iadelerin işlenmesi için özel ekipmanlar gereklidir. Bu nedenle çoğu işletme sınırlı kaynakları ve teknik yeterlilikleri nedeniyle TL faaliyetlerini üçüncü parti TL sağlayıcılarına (3PTLS) devretmektedir. Uygun 3PTLS seçim süreci işletmelerin ekonomik karlılığına ve uzun vadeli gelişimine katkı sunması nedeniyle stratejik olarak önemli bir karardır. 3PTLS seçim kararı, çok sayıda belirsizlik içermesi ve karmaşık doğası gereği çok kriterli karar verme (ÇKKV) problemi olarak ele alınmaktadır. Bu çalışmada, en iyi 3PTLS seçimi için insan düşüncelerindeki belirsizlik ve karmaşıklığı daha iyi yansıtmak amacıyla Pisagor bulanık kümelere dayalı bir grup karar verme modeli olarak Pisagor bulanık TOPSIS yöntemi kullanılarak modellenmiştir. Modelin uygulanabilirliği, bir pil üretim şirketinden alınan verilere dayanan deneysel bir çalışma ile gösterilmiştir. Elde edilen sonuçlar diğer karar verme yöntemleriyle (bulanık TOPSIS, bulanık COPRAS ve klasik TOPSIS) karşılaştırılmış ve çözüm üstünlükleri sunulmuştur. Ayrıca önerilen modelin kararlılığını ve uygulanabilirliğini değerlendirmek için duyarlılık analizi yapılmıştır.

Kabinli jeneratör setleri hem dış mekânda kullanıldığı hem de jeneratör setine koruma sağladıkları için tercih sebebidir. Jeneratör setine uygun bir kabin tasarlarken kullanılan motorun soğutma performansı, tasarım kriteri olarak belirlenmelidir. Bu çalışmada, kabinli bir jeneratör setinin hesaplamalı akışkanlar dinamiği yöntemiyle sayısal analizleri ANSYS FLUENT 19.2 yazılımında gerçekleştirilmiş ve gerçekleştirilen sayısal analizler, deneysel analizlerle karşılaştırılmıştır. Jeneratör emiş bölgesi, atış bölgesi, emiş kesiti ve atış kesiti olarak dörde ayrılmış ve her bir bölgenin akış analizleri gerçekleştirilmiştir. Tüm sistemin basınç farkı 1104C-44TAG2 motorunun verisinde izin verilen basınç farkı değerinden 14,25 Pa yüksek çıkmıştır. Bu farkın jeneratörün çalışma şartlarını ne kadar etkilediğini anlamak için HIOKI test cihazıyla deneyler yapılmış ve jeneratör setinin çalışabileceği maksimum sıcaklığın 3,9 °C düştüğü gözlemlenmiştir. Böylece ileride yapılacak olan çalışmalara referans oluşturulmuştur.

Published: March 2022

In this study, the optimization of the medium components used for the production of lipase enzyme from Cryptococcus albidus D24 was performed using the Plackett-Burman statistical design method (PBD), and the most important nutrients affecting the production of lipase enzyme from D24 strain were determined as the first step. According to PBD, the highest lipase activity (19.34 U/ml/min) was obtained with medium including Tween 80 (X2) 2.5% (v/v), and (g/L) Peptone (X4) 8.0, Yeast Extract (X6) 7.5, Beef Extract (X7) 7.5, Malt Extract (X8) 7.5, NH4Cl (X9) 6.0, NaNO3 (X10) 1.5, (NH4)NO3 (X12) 6.0, (NH4)HCO3(X13) 6.0, MgSO4.7H2O (X15) 1.0, and KH2PO4 (X16) 2.0 at the end of 144 h cultivation. Regarding the concentration effect (CE) values obtained from PBD, NH4Cl (CE=7.1587), olive oil (CE=3.5544), (NH4)HCO3 (CE=3.0747), and tryptone (CE=2.1427) were evaluated as the more effective nutrients among the sixteen compounds studied. After that, the optimum concentrations of these effective compounds were experimented with Response Surface Methodology (RSM). Experimental results showed that the medium containing olive oil (X3) 1.5% (v/v), and (g/L) tryptone (X5) 3.0, NH4Cl (X9) 7.5, and (NH4)HCO3 (X13) yielded maximum lipase activity (12.03 U/ml/min) compared to other studied compounds. Although the maximum lipase activity obtained with RSM methodology was lower than that obtained by PBD, the cost of the nutrients used to produce one-unit enzyme is 0.104 Euro in the PBD, while only 0.0277 Euro is spent in RSM. In other words, the production of lipase using compounds coded X3, X5, X9, and X13 provides a cost-effective process.
