Application of multi sensor data fusion based on Principal Component Analysis and Artificial Neural Network for machine tool thermal monitoring

Due to the various heat sources on a machine tool, there exists a complex temperature distribution across its structure. This causes an inherent thermal hysteresis which is undesirable as it affects the systematic tool –to-workpiece positioning capability. To monitor this, two physical quantities (temperature and strain) are measured at multiple locations. This article is concerned with the use of Principal Component Analysis (PCA) and Artificial Neural Networks (ANN) to fuse this potentially large amount of data from multiple sources. PCA reduces the dimensionality of the data and thus reduces training time for the ANN which is being used for thermal modelling. This paper shows the effect of different levels of data compression and the application of rate of change of sensor values to reduce the effect of system hysteresis. This methodology has been successfully applied to the ram of a 5-axis gantry machine with 90 % correlation to the measured displacement

Applications for RFID in pharmaceutical industry

Security and safety are two important features desired in pharmaceutical supply chain and achieving the same is a challenging task. The need to secure and authenticate pharmaceutical products has increased tremendously with the emerging counterfeit product market. The motivation to introduce counterfeit pharmaceutical products in the supply chain could be to gain rapid economic benefits or affecting the reputation of strong brand in the pharmaceutical industry. RFID technology can be used to deter counterfeiting attempts. It can also be used in various other domains in the pharmaceutical industry. The main aim of this paper is to outline all the applications of RFID in the pharmaceutical industry. After explaining the main applications, we discuss how information hiding techniques could be used with RFID to offer efficient expiry date management, pharmaceutical tamper detection, and fraud detection and prevention

Comparison of media selection in the U.S. and Indian advertising industries

Advertising is necessary to establish a brand and to increase the sale of the products. Media planning is an important phase of any advertising campaign. The purpose of this study was to determine the media types used in the advertising industries in India and in the U.S. Media professionals from five Indian advertising agencies and five U.S advertising agencies were interviewed to find out the media selection in both countries. The identification of media was then followed by the comparison of media selection in India and the U.S. The secondary research was carried out to find out media environment in both countries, which included information about the number of newspaper titles published, TV channels, and radio stations in both countries. The media selection depends upon different factors such as cost, geography and demographics. The secondary research was carried out to find out the differences in geography, demographics and culture between India and the U.S. The TV medium is the most important medium for advertising in both countries. Radio advertising is used in both countries but has become stagnant in India. The Internet is in its initial growing stage in India; however, in the U.S., the Internet has become the second most important medium. The major difference was found in the state of print media in India and in the U.S. In U.S., the use of print media is declining, but, in India, it is widely used for advertising. Other media types such as mobile, out-of-home, and social media are used in both countries, but the degree of the usage is different. The secondary research showed that the media environment in both countries is different. The number of newspaper titles is more in India than in the U.S. The number of TV stations is more in the U.S. than in India. The geographical area of the U.S is more than that of India, but the population in India is more than the population of the U.S. There are different ethnic groups in both countries. The literacy rate in the U.S. is more than India. There are differences in the cultures and etiquette. These factors affect the media selection and, thus, there are differences in media selection between both countries

Jaffa Port, Israel: From a thriving port town to a socio-ethnic enclave

The material extant of the fortifications of Jaffa, the physical markers of memory, narrates the contrasting status and evolution of one of the oldest port towns in Israel: from grandiose to decline, from thriving multicultural neighbourhoods to immigrant communities over time, from town centre to marginalised significance and shifting centralities in the wake of political and economic events. Its town centre, propagating social interaction, existed through complex and evolving agricultural, industrial, and residential land uses. This port town bears a testimony to the dynamic and enormous shifts in land use, communities, and collective social memory. The alternate port of Tel Aviv came into existence during the revolt in 1936-39 by Arabs of Mandatory Palestine. The drastic decline of the Arab population in Jaffa and its environs and the rise in the Jewish population in the new modern city of Tel Aviv was an antagonistic process of negation and exclusion. The asymmetric planning of Tel Aviv that emerged in the early 1900s identified it as uncivilised geography, turning into a dilapidated district. Communal and national identities were built on the premise of antithesis giving rise to significant demographic transformations. This socio-spatial metamorphosis of Tel Aviv-Jaffa became a representational space leading to physical and cognitive boundaries evident in the planning policies. Since the mid-1980s, the spatial overturns have led to the radical restructuring of the urban space through gentrification with political and socio-economic implications such as population displacement and the production of urban alterities. This oxymoron of creative destruction suggests the tensions at the heart of urban life that embodies the erasure and re-inscription of culture and economics. This article will explore the historical evolution of the old port town, cultural geography, and the current state of exclusion and gentrification in Jaffa, and underlines the need for discourse on socio-spatial analysis and assessment for decision-making processes for urban heritage design.&nbsp

SITUATIONAL AWARENESS WHILE FLYING A UAV: A COMPARISON OF VIDEO GAMER AND NON-VIDEO GAMER PILOTS

Unmanned aerial vehicles, also known as drones, are an important part of today’s society due to their vast use in various industries. However, there is a growing concern about the lack of situational awareness of drone operators due to the increase in the number of drone mishaps. This has led researchers to investigate if pilots or video game players would be better unmanned aerial vehicle operators due to the similarity of flying an aircraft and playing video games to flying a drone. Hence, the purpose of this study is to investigate whether the video game playing habits of pilots can affect their situational awareness while flying an unmanned aerial vehicle. This will be done by comparing the situational awareness of non-video game playing pilots and video game playing pilots while they operate a drone in a drone simulator. The study expects to find that pilots who play video games would have better situational awareness while flying a drone when compared to pilots who do not play video games. This study may help organizations that use unmanned aerial vehicles better select their operators. It can also be used to improve drone training methods by implementing the use of drones. Keywords: Situational Awareness, Unmanned Aerial Vehicles, Aviation Safety, Pilot, Video Game Player, Personnel Selectio

Future-mapping technique for a non-profit organization

Organizations often find themselves in a difficult situation when strategizing for the future. This report aims to map the future of a non-profit organization. According to the author, future mapping means assessing the future possibilities, assessing the available options, and using these analyses to direct the organization. The work covers the gap between future studies and strategies for non-profit organizations as a by-product. The technique is applied in the case of a non-profit organization, Modus ry, which supports the handcrafting entrepreneurs and businesses in Finland. The work has two resulting outputs. One is the recommendations for the association, and the second is a technique for future mapping. When developing the technique, the work may also be described as a recombination of individual already existing concepts to get the most out of them. These concepts include scenario-based strategy, future wheels, and analysis tools like context diagram, why-why diagram, stakeholder map, analysis tables, etc. The technique is replicable and valid. Strategizing for long-term possibilities while at the same time integrating short-lasting trends and changes is the highlight of the technique
