CHOOSING THE OPTIMUM TECHNOLOGICAL ALTERNATIVE FOR 3D PRINTING

The period between the design of a product and the moment from which the product is no longer profitable on the market represents its life cycle. Decreasing the profitability of the product on the market means that the company must find solutions to launch a new product. The new products can be assimilated in the manufacture by own conception at the level of the enterprise, on the basis of the purchased manufacturing licenses and on the basis of the reference models of a similar product existing on the market. The paper presents the methodology for choosing the optimal technological variant for a part manufactured by 3D printing using two technological variants, through the criterion of unit technological cost and the criterion of total technological cost. Depending on the relationship between the size of the manufacturing batch and the calculated critical size of the manufacturing batch, respectively between the unit technological cost and the total technological cost for the two technological variants, the optimal technological variant of manufacturing can be established.

DEVELOPMENT OF A SMART OCEAN RADIATION MONITORING SYSTEM

Ocean radiation monitoring systems (ORMSs) are an essential component in the radiation early warning network that monitors radiation exposure and estimates radioactive propagation induced by nuclear activities or nuclear accidents in the sea. Numerous systems have been developed and installed in the radiation warning network in different countries. However, there is not any similar product that has been studied and developed in Vietnam. This paper presents a complete process in designing and manufacturing a marine buoy integrated with a radiation sensor. The radiation detector can measure both dose rate and radiological spectrum. The ORMS also combines multimodal data transmission and various programmed software for data processing, signal transmission, and system control. Therefore, the proposed configuration system has potential application in terms of performance and maintenance.

Market Segmentation Analysis in Tourism: A Perspective Paper

No two tourists are the same. This insight stands at the core of market segmentation. Pursuing a segmentation strategy as a tourist destination or a tourism business means catering to the specific needs of certain types of tourists (market segments), rather than attempting to satisfy the needs of the entire tourist market by effectively targeting the average tourist. But which market segments should a tourist destination or business target? Market segmentation analysis helps answer this question. Market segmentation analysis is “the process of grouping consumers into naturally existing or artificially created segments of consumers who share similar product preferences or characteristics” (Dolnicar, Grün & Leisch, 2018, p. 11).

Online Product Hiring System

Nowadays, it is difficult to find a lessor who is willing to rent a product at an appropriate price for a few days. At times, even if he is willing to rent it becomes difficult for him to find people willing to buy/ hire his products. This project aims to solve this problem faced by the lessor and the customer. The Online Product Hiring System is an an online platform where in the user can hire goods of his/her choice. The user must create an account on the platform if he wants to hire. The system will have different categories. The software system will have multiple vendors wanting to rent their products. The consumer can view the ratings of the product as well as review and rate the product after use. The product can be tracked at what stage it is in the purchase cycle. There will be recommendations also for the user about a similar product. The buyer can view his/hers past orders. The system will be supported on mobile version with notifications.

e-SimNet: a visual similar product recommender system for E-commerce

<span>Visual similarity recommendations have an immense role in E-commerce portals. Fetching the appropriate similar products and suggesting to the buyers based on the product image's visual features is complex. Here in our research, we presented an efficient E-commerce similar product network model (e-SimNet) for visually similar recommendations. To achieve our objective, we have performed image feature extraction and generating embeddings using deep learning techniques and built an Index tree using the approximate nearest neighbor oh yeah (ANNOY) algorithm. Further, we have fetches top-N the near similar items using distance measure. We have benchmarked our model in terms of accuracy, error rate, and results show that better than other state-of-the-art approaches with 96.22% of accuracy.</span>

Microalgae as Future Superfoods: Fostering Adoption through Practice-Based Design Research

Consumers’ eating habits are gradually changing. In the next few decades, this shift will not be solely dictated by individuals’ decisions but by the need to feed an ever-increasing population in the face of global resources’ impoverishment. Novel superfoods rich in nutrients and produced with sustainable methods, including microalgae, maybe a solution. However, their unusual aspect, the palatability, and the lack of knowledge by most people could be obstacles to adoption. This study aims at encouraging the use of microalgae as food, highlighting the importance that design plays in the transition towards more sustainable production and consumption patterns. Through practice-based design research, characterized by empirical experiments, a survey, an engaging workshop, and the development of a fully-functional open-source product, the authors conceptualize a theoretical framework within which similar product-service systems could thrive. This real-world experimentation is of interest for academics, professionals, makers in the field of design, etc. It suggests that multidisciplinarity, education, and replicability are the keys to addressing this topic and paves the way for further technical and humanistic research.

Design of PLC Based Automated Food Processing Machine

Ever-changing work expects technological advancement in all the tasks carried out by humans. Cooking is one such process, which is presently majorly carried out by human beings. Though a lot of automation has been happening in the area of food processing, involving a larger quantity of food production in a commercial or institutional setup. But very less automation is adapted in domestic or household cooking. In the proposed work, we propose to manufacture a system involving computers and electro-mechanical components for cooking two of the most widely consumed Indian delicacies Dosa (Pancake) and Idli (Rice cake). Reported work discusses the detailed mechanical fabrication of the device, including the process of automation implemented on Programmable Logic Controller (PLC). A detailed comparison is tabulated comparing the similar product to highlight the working of the proposed system

Optimal product release time for a new high-tech startup firm under technical uncertainty

<p style='text-indent:20px;'>Decision makers of new high-tech startup firms always want to choose an optimal time to launch their products which are under research and development (R&amp;D) to obtain the maximum net income of these firms. However, existing models fail to consider the optimal release time of products for these new high-tech startup firms. In this paper, the optimal time to launch the product of the R&amp;D project is assumed to be the first time when the product of the R&amp;D project is released to the market. Based on this assumption, we develop a continuous-time model to find the optimal time at which the startup firm launches its product of the R&amp;D project by considering the price of the similar product. Employing the methods of dynamic programming and variational inequalities, we also provide a closed form solution to our model. We also find that these high-tech startup firms prefer to delay their product release time when the price of the similar product is at a phase of rapid growth or the price has considerable uncertainty. Moreover, some numerical examples are provided to investigate the properties of our model.</p>

Amino acid sulfonamides based on 4-(1-oxo-1H-isochromen-3-yl)benzenesulfonyl chloride

The creation of new amino acid derivatives of 4-(1-oxo-1H-isochromen-3-yl)benzenesulfonyl chloride 1 was investigated. The interaction of the sulfonyl chloride 1 with amino acid methyl esters (hydrochlorides) in 1,4-dioxane in the presence of triethylamine led to the corresponding amino acid sulfonamide derivatives of isocoumarin. The reaction of the sulfonyl chloride 1 with phenylalanine in the basic aqueous solution was complicated by the lactone system disclosure and led to 2'-carboxydeoxybenzoin ultimately (namely, 2-(2-(4-(N-(1-carboxy-2-phenylethyl)sulfamoyl)phenyl)-2-oxoethyl)benzoic acid). Similar product was obtained by the alkali hydrolysis of methyl ((4-(1-oxo-1H-isochromen-3-yl)phenyl)sulfonyl)leucinate.

PENGARUH PERSEPSI KEMIRIPAN, KONSEP MEREK DAN PESAN IKLAN TERHADAP RESPON KONSUMEN DALAM MENGEVALUASI PERLUASAN MEREK

Introduction: This study aims to determine the effect of product category similarity when associated with brand concepts and advertising messages on consumer responses in evaluating brand expansion. To get the research objective, two studies were conducted sequentially.Methods: The first study used experiments conducted on the similarity category of the product and the brand concept. The second study uses experiments conducted on product similarity categories and advertising messages. Experiments in both studies were carried out using the between-subject method with 240 undergraduate students at the Faculty of Economics and Business, Airlangga University (120 students for each study) as participants.Results: The experimental results from the first study show that the prestigious brand concept has a better ability (compared to the functional brand concept) to carry out brand expansion both in product categories that are similar or not similar to the original brand. The experimental results from the second stage study show that a prestigious brand will be able to increase its ability to expand the brand if the product is advertised with a social-adjustive message for similar product categories, and for dissimilar product categories it will be more effective if advertised with a value-expressive message.Conclusion and suggestion: Companies that do brand extensions to different product categories are advised to use ads with value-expressive messages to make them more effective.
