Academic literature on the topic 'Other information and computing sciences not elsewhere classified'

Purpose – The purpose of this paper is to analyze the use of electronic journals (e-journals) by the scientists of Council of Scientific and Industrial Research-Institute of Genomics and Integrative Biology (CSIR-IGIB) – a center of excellence in the field of genomics and integrative biology situated in Delhi, India. Design/methodology/approach – The paper is based on the results of a well-structured questionnaire administered to all the scientists of the institute for the purpose of data collection. Findings – The main findings are that the scientists are more attracted toward e-journals specially on those provided by CSIR-NISCAIR Consortia, NKRC than those available via direct subscription. From this survey, the investigator has been able to find out that almost all the scientists are consulting e-journals from their campus cabin, not only for research purposes but also to update their own knowledge. The infrastructure to use e-journals are superb and there is no technological problem specially hardware and software support with high bandwidth of Internet speed exists here, as CSIR-IGIB uses largest computing facility (four Tflop/s) in Asia outside Japan (ranked 158th among the World’s Top 500 Super Computers). Respondents also identified that there is dire need for training in using e-resources and retrieving pinpointed information from the databases. Research limitations/implications – The present paper consists only of scientists and the geographical area is restricted to CSIR-IGIB, Delhi. The scope of the paper can be extended to additional CSIR libraries. A comparative study can also be made among some biological research libraries of CSIR Institutes. Originality/value – There are a number of studies on the use of e-journals by CSIR scientists, but this is the first of its kind which covers scientists of IGIB that has the largest computing facility (four Tflop/s) in Asia outside Japan. As such, it should pave the way for research and lead a model role for other CSIR Institutes as well as elsewhere.

Although well over 1000 journal articles, conference papers, books, technical notes and theses have been written on the subject of information technology (IT) evaluation, only a relatively small subset of this literature has been concerned with the core issues of what precisely is meant by the term ‘value’ and with the process of making (specifically) IT investment decisions. All too often, the problem and highly complex issue of value is either simplified, ignored or assumed away. Instead the focus of much of the research to date has been on evaluation methodologies and, within this literature, there are different strands of thought which can be classified as partisan, composite and meta approaches to evaluation. Research shows that a small number of partisan techniques are used by most decision makers with a minority using a single technique and a majority using a mixture of such techniques of whom a substantial minority use a formal composite approach. It is argued that, in mapping the set of evaluation methodologies on to what is termed the investment opportunity space, that there is a limit to what can be achieved by formal rational evaluation methods. This limit becomes evident when decision makers fall back on ‘gut feel’ and other non-formal/rigorous ways of making decisions. It is suggested that an understanding of these more complex processes and decision making, in IT as elsewhere, needs tools drawn from philosophy and psychology.

Mapping surface water over time provides the spatially explicit information essential for hydroclimatic research focused on droughts and flooding. Hazard risk assessments and water management planning also rely on accurate, long-term measurements describing hydrologic fluctuations. Stream gages are a common measurement tool used to better understand flow and inundation dynamics, but gage networks are incomplete or non-existent in many parts of the world. In such instances, satellite imagery may provide the only data available to monitor surface water changes over time. Here, we describe an effort to extend the applicability of the USGS Dynamic Surface Water Extent (DSWE) model to non-US regions. We leverage the multi-decadal archive of the Landsat satellite in the Google Earth Engine (GEE) cloud-based computing platform to produce and analyze 372 monthly composite maps and 31 annual maps (January 1988–December 2018) in Cambodia, a flood-prone country in Southeast Asia that lacks a comprehensive stream gage network. DSWE relies on a series of spectral water indices and elevation data to classify water into four categories of water inundation. We compared model outputs to existing surface water maps and independently assessed DSWE accuracy at discrete dates across the time series. Despite considerable cloud obstruction and missing imagery across the monthly time series, the overall accuracy exceeded 85% for all annual tests. The DSWE model consistently mapped open water with high accuracy, and areas classified as “high confidence” water correlate well to other available maps at the country scale. Results in Cambodia suggest that extending DSWE globally using a cloud computing framework may benefit scientists, managers, and planners in a wide array of applications across the globe.

A Review of: Orme, Verity. “You will be…: A Study of Job Advertisements to Determine Employers’ Requirements for LIS Professionals in the UK in 2007.” Library Review 57.8 (2008): 619-33. Objective –To determine what skills employers in the United Kingdom (U.K.) want from information professionals as revealed through their job advertisements. Design – Content analysis, combining elements of both quantitative and qualitative content analysis. Orme describes it as “a descriptive non-experimental approach of content analysis” (62). Setting – Data for this study were obtained from job advertisements in the Chartered Institute of Library and Information Professional’s (CILIP) Library and Information Gazette published from June 2006 through May 2007. Subjects – A total of 180 job advertisements. Methods – Job advertisements were selected using a random number generator, purposely selecting only 15 advertisements per first issue of each month of the Library and Information Gazette (published every two weeks). The author used several sources to create an initial list of skills required by information professionals, using such sources as prior studies that examined this topic, the Library and Information Science Abstracts (LISA) database thesaurus, and personal knowledge. Synonyms for the skills were then added to the framework for coding. Skills that were coded had to be noted in such a way that the employer plainly stated the employee would be a certain skill or attribute or they were seeking a skill or a particular skill was essential or desirable. Skills that were stated in synonymous ways within the same advertisement were counted as two incidences of that skill. Duties for the position were not counted unless they were listed as a specific skill. Data were all coded by hand and then tallied. The author claims to have triangulated the results of this study with the literature review, the synonym ring used to prepare the coding framework, and a few notable studies. Main Results – A wide variety of job titles was observed, including “Copyright Clearance Officer,” “Electronic Resources and Training Librarian,” and “Assistant Information Advisor.” Employers represented private, school, and university libraries, as well as legal firms and prisons. Fifty-nine skills were found a total of 1,021 times across all of the advertisements. Each advertisement averaged 5.67 requirements. These skills were classified in four categories: professional, generic, personal, and experience. The most highly noted requirement was professional experience, noted 129 times, followed by interpersonal/communication skills (94), general computing skills (63), enthusiasm (48), and team-working skills (39). Professional skills were noted just slightly more than generic and personal skills in the top twenty skills found. Other professional skills that were highly noted were customer service skills (34), chartership (30), cataloguing/classification/metadata skills (25), and information retrieval skills (20). Some notable skills that occurred rarely included Web design and development skills (6), application of information technology in the library (5), and knowledge management skills (3). Conclusion – Professional, generic, and personal qualities were all important to employers in the U.K.; however, without experience, possessing these qualities may not be enough for new professionals in the field.

Objective To systematically review the publications on ecological momentary assessment (EMA) relating to physical activity (PA) behavior in order to classify the methodologies, and to identify the main mHealth technology-based tools and procedures that have been applied during the first 10 years since the emergence of smartphones. As a result of this review, we want to ask if there is enough evidence to propose the use of the term “mEMA” (mobile-based EMA). Design A systematic review according to PRISMA Statement (PROSPERO registration: CRD42018088136). Method Four databases (PsycINFO, CINALH, Medline and Web of Science Core Collection) were searched electronically from 2008 to February 2018. Results A total of 76 studies from 297 potential articles on the use of EMA and PA were included in this review. It was found that 71% of studies specifically used “EMA” for assessing PA behaviors but the rest used other terminology that also adjusted to the inclusion criteria. Just over half (51.3%) of studies (39) used mHealth technology, mainly smartphones, for collecting EMA data. The majority (79.5%) of these studies (31 out of 39) were published during the last 4 years. On the other hand, 58.8% of studies that only used paper-and-pencil were published during the first 3 years of the 10-year period analyzed. An accelerometer was the main built-in sensor used for collecting PA behavior by means of mHealth (69%). Most of the studies were carried out on young-adult samples, with only three studies in older adults. Women were included in 60% of studies, and healthy people in 82%. The studies lasted between 1 and 7 days in 57.9%, and between three and seven assessments per day were carried out in 37%. The most popular topics evaluated together with PA were psychological state and social and environmental context. Conclusions We have classified the EMA methodologies used for assessing PA behaviors. A total of 71% of studies used the term “EMA” and 51.3% used mHealth technology. Accelerometers have been the main built-in sensor used for collecting PA. The change of trend in the use of tools for EMA in PA coincides with the technological advances of the last decade due to the emergence of smartphones and mHealth technology. There is enough evidence to use the term mEMA when mHealth technology is being used for monitoring real-time lifestyle behaviors in natural situations. We define mEMA as the use of mobile computing and communication technologies for the EMA of health and lifestyle behaviors. It is clear that the use of mHealth is increasing, but there is still a lot to be gained from taking advantage of all the capabilities of this technology in order to apply EMA to PA behavior. Thus, mEMA methodology can help in the monitoring of healthy lifestyles under both subjective and objective perspectives. The tendency for future research should be the automatic recognition of the PA of the user without interrupting their behavior. The ecological information could be completed with voice messages, image captures or brief text selections on the touch screen made in real time, all managed through smartphone apps. This methodology could be extended when EMA combined with mHealth are used to evaluate other lifestyle behaviors.

Purpose The purpose of this paper is to conduct a comprehensive review of the noteworthy contributions made in the area of the Feedforward neural network (FNN) to improve its generalization performance and convergence rate (learning speed); to identify new research directions that will help researchers to design new, simple and efficient algorithms and users to implement optimal designed FNNs for solving complex problems; and to explore the wide applications of the reviewed FNN algorithms in solving real-world management, engineering and health sciences problems and demonstrate the advantages of these algorithms in enhancing decision making for practical operations. Design/methodology/approach The FNN has gained much popularity during the last three decades. Therefore, the authors have focused on algorithms proposed during the last three decades. The selected databases were searched with popular keywords: “generalization performance,” “learning rate,” “overfitting” and “fixed and cascade architecture.” Combinations of the keywords were also used to get more relevant results. Duplicated articles in the databases, non-English language, and matched keywords but out of scope, were discarded. Findings The authors studied a total of 80 articles and classified them into six categories according to the nature of the algorithms proposed in these articles which aimed at improving the generalization performance and convergence rate of FNNs. To review and discuss all the six categories would result in the paper being too long. Therefore, the authors further divided the six categories into two parts (i.e. Part I and Part II). The current paper, Part I, investigates two categories that focus on learning algorithms (i.e. gradient learning algorithms for network training and gradient-free learning algorithms). Furthermore, the remaining four categories which mainly explore optimization techniques are reviewed in Part II (i.e. optimization algorithms for learning rate, bias and variance (underfitting and overfitting) minimization algorithms, constructive topology neural networks and metaheuristic search algorithms). For the sake of simplicity, the paper entitled “Machine learning facilitated business intelligence (Part II): Neural networks optimization techniques and applications” is referred to as Part II. This results in a division of 80 articles into 38 and 42 for Part I and Part II, respectively. After discussing the FNN algorithms with their technical merits and limitations, along with real-world management, engineering and health sciences applications for each individual category, the authors suggest seven (three in Part I and other four in Part II) new future directions which can contribute to strengthening the literature. Research limitations/implications The FNN contributions are numerous and cannot be covered in a single study. The authors remain focused on learning algorithms and optimization techniques, along with their application to real-world problems, proposing to improve the generalization performance and convergence rate of FNNs with the characteristics of computing optimal hyperparameters, connection weights, hidden units, selecting an appropriate network architecture rather than trial and error approaches and avoiding overfitting. Practical implications This study will help researchers and practitioners to deeply understand the existing algorithms merits of FNNs with limitations, research gaps, application areas and changes in research studies in the last three decades. Moreover, the user, after having in-depth knowledge by understanding the applications of algorithms in the real world, may apply appropriate FNN algorithms to get optimal results in the shortest possible time, with less effort, for their specific application area problems. Originality/value The existing literature surveys are limited in scope due to comparative study of the algorithms, studying algorithms application areas and focusing on specific techniques. This implies that the existing surveys are focused on studying some specific algorithms or their applications (e.g. pruning algorithms, constructive algorithms, etc.). In this work, the authors propose a comprehensive review of different categories, along with their real-world applications, that may affect FNN generalization performance and convergence rate. This makes the classification scheme novel and significant.

For active volcanoes, knowledge about probabilities of eruption and impacted areas becomes valuable information for decision-makers to develop short- and long-term emergency plans, for which probabilistic volcanic hazard assessment (PVHA) is needed. High-resolution or spatially extended PVHA requires extreme-scale high-performance computing systems. Within the framework of ChEESE (Center of Excellence for Exascale in Solid Earth; www.cheese-coe.eu), an effort was made to generate exascale-suitable codes and workflows to collect and process in some hours the large amount of data that a quality PVHA requires. To this end, we created an optimized HPC-based workflow coined PVHA_HPC-WF to develop PVHA for a volcano. This tool uses the Bayesian event tree methodology to calculate eruption probabilities, vent-opening location(s), and eruptive source parameters (ESPs) based on volcano history, monitoring system data, and meteorological conditions. Then, the tool interacts with the chosen hazard model, performing a simulation for each ESP set or volcanic scenario (VS). Finally, the resulting information is processed by proof-of-concept-subjected high-performance data analytics (HPDA) scripts, producing the hazard maps which describe the probability over time of exceeding critical thresholds at each location in the investigated geographical domain. Although PVHA_HPC-WF can be adapted to other hazards, we focus here on tephra (i.e., lapilli and ash) transport and deposition. As an application, we performed PVHA for Campi Flegrei (CF), Italy, an active volcano located in one of the most densely inhabited areas in Europe and under busy air traffic routes. CF is currently in unrest, classified as being in an attention level by the Italian Civil Protection. We consider an approximate 2,000 × 2,000 × 40 km computational domain with 2 km grid resolution in the horizontal and 40 vertical levels, centered in CF. To explore the natural variability and uncertainty of the eruptive conditions, we consider a large number of VSs allowing us to include those of low probability but high impact, and simulations of tephra dispersal are performed for each of them using the FALL3D model. Results show the potential of HPC to timely execute a vast range of simulations of complex numerical models in large high-resolution computational domains and analyze great volumes of data to obtain quality hazard maps.

What is a machine? As part of his answer to this, historian and philosopher of technology Lewis Mumford cites a classic definition: "a machine is a combination of resistant bodies so arranged that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinant motions" (Reuleaux [1876], qtd. in Mumford, Technics and Civilisation 9). Mumford's own definition is focussed on machines as part of a technological continuum between human body and automaton: Machines have developed out of a complex of non-organic agents for converting energy, for performing work, for enlarging the mechanical or sensory capacities of the human body, or for reducing to a mensurable order and regularity the processes of life. The automaton is the last step in a process that began with the use of one part or another of the human body as a tool. (9-10) The tool and the machine can be distinguished along this technological continuum, with the tool more dependent on "the skill and motive power of the operator", subject to "manipulation", and potentially more flexible in its uses, whereas the machine lends itself more to "automatic action" of a specialised kind. However, it is difficult to ultimately separate them, since the embodied skill of the tool-user becomes more mechanical and reflexive with practice (Technics and Civilisation 10), while the machine also evolves along increasingly organic lines (367), and there are common examples of hybrid machine-tools like the lathe or drill, which combine "the accuracy of the finest machine ... with the skilled attendance of the workman" (10). A powerfully attractive feature of the computer is that it is an effective hybrid of machine and tool: like a machine it performs many specialised functions at super-human speed and accuracy on command, but like a tool it is flexible and adaptable (through add-on software and plug-in peripherals) to a seemingly endless variety of users and uses. Fascinating Assemblages The automatic machine ... involves the notion of an external source of power, a more or less complicated inter-relation of parts, and a limited kind of activity. From the beginning the machine was a sort of minor organism, designed to perform a single set of functions. (Mumford, Technics and Civilisation 11) The autonomy of the machine is perhaps its most fascinating aspect. That the machine is an assemblage of parts and restricted functions -- a "minor organism" as Mumford puts it -- suggests to us a body. There is something ineluctably erotic about scenes of lubricated pistons moving in and out of cylinders, or greased gear wheels moving around each other, and a masturbatory energy seems to be involved in the machine that repetitively and by itself performs the same limited actions over and over and over. While there are parallels between masculine masturbation and machinic repetition, there are also associations with femininity. As Andreas Huyssen pointed out, the modern machine became associated with a dangerous female sexuality and took the place of the early moderns' untamed Mother Nature as the principal representative of non-human forces with autonomy and agency that could evade human control. But arguably, expressed fears of machinic autonomy are the flip side of a wish for it, arising from masculine reproductive fantasies that have been played out in technoscience by generations of fictional and real-life Frankensteins fanatically seeking to create artificial life in the form of technoscientific brainchildren (who are nevertheless often neglected and left to run wild at birth). At a conscious level, machines express what may be interpreted as anal-sadistic desires for order, regularity and control, but unconsciously there is an element of masochistic pleasure in being passive, in yielding up control to the machine, in letting it set the scene and determine the actions and roles for the humans as well as non-humans (Sofia, "Contested Zones", and "Mythic Machine" 44-8). Machinic Zeal What is the use of conquering nature if we fall a prey to nature in the form of unbridled men? What is the use of equipping mankind with mighty powers to move and build and communicate, if the final result of this secure food supply and this excellent organisation is to enthrone the morbid impulses of a thwarted humanity? (Mumford, Technics and Civilisation 366) With his emphasis on the social context and drives towards technology, Mumford (Technics and Civilisation 364-5) suggests that while some kinds of machines have existed for thousands of years, what we have come to think of as the mechanical age only arose with the widespread adoption of the machine as a way of securing order, regularity and calculability of physical and human resources, coupled with the ideological shift which made the machine into "a goal of desire" and an object of almost obsessive veneration from the mid-18th century to the early 20th century. Now, he said (writing first in the early 1930s) faith in the machine has been somewhat shaken, and it is no longer seen as "the paragon of progress" but as "merely a series of instruments" to be used when useful; yet despite this loss of faith the machine in capitalist contexts continues to be "over-worked, over-enlarged, over-exploited because of the possibility of making money out of it" (Technics and Civilisation 367). Almost seventy years after Mumford was writing, the obsessive zeal for the machine still has not completely disappeared, but has been displaced from giant smoke-puffing steel assemblages, whirling cogs and gearwheels, or the motors driving trains, cars and planes, and onto the silicon, plastic and light of computers (whose machineries of production and assembly are largely hidden off-shore to the bulk of users, thereby producing the illusion of "post-industrial" societies). The computer is now the paragon of progress and has become the "defining technology" of our age (Bolter), its place reinforced by an actively boosterist popular press (e.g. popular computing magazines; regular computer supplements in newspapers). Sociotechnical Not Posthuman Mumford continually makes the point that questions posed by/in technology are never answerable only technologically. It always comes down to human choices, and even when the results of these "are uncontrollable they are not external" to human culture: Choice manifests itself in society in small increments and moment-to-moment decisions as well as in loud dramatic struggles; and he who does not see choice in the development of the machine merely betrays his incapacity to observe cumulative effects until they are bunched together so closely that they seem completely external and impersonal. (Mumford, Technics and Civilisation 6) In a certain way Mumford's perspective anticipates actor-network theory, which looks at artefacts -- including machines -- as parts of sociotechnical networks that involve human decisions, including about the distribution of agency to non-humans. Even in the most automated machine, Mumford argues "there must intervene somewhere, at the beginning and end of the process ... the conscious participation of a human agent" (10). Actor-network studies of the development of scientific and technological artefacts aim in part to critique the sense of the external, impersonal or inevitable in scientific and technical 'progress' by insisting that "things might have been otherwise" (Bijker & Law 3), not just at the beginning and end, but all the way through the process of an artefact's development and use. The artefact is studied as a particular outcome of a set of decisions and performances made in the midst of contingencies affecting human and non-human actors with conflicting goals and contested powers within a dynamic sociotechnical network. Although actor-network theory is very interested in non-human agents, it does not, as do some recent participants in and theorists of cyberculture, celebrate the so-called post-human. There can be no agentic machines without there having been human competencies downloaded into them; there can be no technical order that is not also social and cultural. As Latour argues, the modernist work of purification has tried vainly to impose a separation between the social and technical, denying their mutual inextricability. From this Latourian perspective, the notion of the "post-human" is not, as it appears to be, post modern, but thoroughly modern. It carries through the quintessentially modernist project of denying after the fact the human agency and capacities that have been invested in producing hybrid artefacts which are then proclaimed as extra-human; it denies the cumulative effects of sociotechnical choices and instead represents the machinic imperative as somehow impersonal and external to human affairs. The notion of the posthuman can readily reinforce the pervasive popular cultural myths of technological inevitability and dominance, conveniently for those humans and corporations who actually do profit from decisions they make about developing and marketing machines of increasing autonomy, intelligence and subtlety. Machines and Provision The role of the machine has been overemphasised in histories of technology, according to Mumford. For aside from tools and machines which perform dynamic actions, there are technologies of containment and supply, which he categorizes as utensils (like baskets or pots), apparatus (such as dye vats, brick kilns), utilities (reservoirs, aqueducts, roads, buildings) and the modern power utility (railroad tracks, electric transmission lines). Some of the most effective adaptations of the environment came, not from the invention of machines, but from the equally admirable invention of utensils, apparatus, and utilities. ... But since people's attention is directed most easily to the noisier and more active parts of the environment, the role of the utility and the apparatus has been neglected ... both [tool and utensil] have played an enormous part in the development of the modern environment and at no stage in history can the two means of adaptation be split apart. Every technological complex includes both: not least our modern one. (Technics and Civilisation, 11-2). The development of various utensils and apparatus for storage (urns, granaries) and flow (irrigation, aqueducts) was essential for the emergence of settled agricultural communities in the neolithic period (Mumford, Technics and Human Development 140-1). As I explore in a related article (Sofia, "Container"), Mumford finds a prudish sexism in the relative neglect of technologies evocative of the female organs of storage, nutrition and transformation, compared with the overemphasis on technologies that are extensions of the muscular masculine body (Technics and Human Development, 140). However, the contrast between dynamic, noisy, active and autonomous machines, and passive, quiet, backgrounded containers cannot be sustained. For one the utensil even in its most basic form, has something machinic about it: a container can perform its function autonomously, without needing manipulation like a tool. Further, it is arguable that holding or containing is not simply a property of a shaped space, but a form of action in itself. Moreover in practice there are many hybrids of machine and utensil or utility, for example in domestic technologies like the food processor, a container with a machine-driven blade, or the washing machine, featuring a tub with mechanical agitation and rotary motion. Although Mumford is primarily interested in the machine, he observes that as modern "neotechnics" proceeds to develop ever more sophisticated machinery, so does it evolve more complex technologies of containment, as described in this passage which depicts both machines and utilities as active agents: Behind the façade [of the crisp lines of steel and glass that define the modern built environment] are rows and rows of machines, weaving cotton, transporting coal ... [etc.], machines with steel fingers and lean muscular arms, with perfect reflexes, sometimes even with electric eyes. Alongside them are the new utilities -- the coke oven, the transformer, the dye vats -- chemically cooperating with these mechanical processes, assembling new qualities in chemical compounds and materials. Every effective part in this whole environment represents an effort of the collective mind to widen the province of order and control and provision. (Technics and Civilisation, 356) Another way of getting the over-emphasised machine back into proportion is to look more closely at what it is used for, what purposes it serves. Mumford writes of the machine as part of the effort to produce "order and regularity" into the processes of life (10); to "widen the province of order and control and provision" (356) or to produce a "secure food supply and ... excellent organisation" (366). In other words, the machine is serving the goals typically associated with utensils, utilities and apparatus: smoothing out fluctuations in supply and distributing resources more evenly. Likewise Mumford suggests that in the back of developments of machine and tool is the effort to adapt by extending the body's powers and/or by altering the environment, so that, for example, instead of a physiological adaptation to cold through hair growth or hibernation, "there is an environmental adaptation, such as that made possible by the use of clothes and the erection of shelters" (10). These technologies are not machines, but container technologies, in the province of what philosopher of technology Don Ihde would call "background technics". We can think of the shift in emphasis here in relation to the example of road works. The large machines for bulldozing a path and laying down layers of road surface are very impressive in their size, power and technical capacity. But the road surface could not be laid down without there being technologies (including hybrids of machine and container, like the pick-up truck) for transporting, storing and mixing the materials used. And when it is done, the big machines lumber off elsewhere, and what we have before us is a road, a utility which facilitates orderly communication, transport and the supply of people and materials. In other words, these machines have served the goal of provisioning. The machine can enthral us with its autonomy, its alterity, its thingness, but as Heidegger has claimed, even such a powerful and seemingly stand-alone machine as a plane on a runway ready for take-off is ultimately just a "completely unautonomous" element when considered as part of a global system ordered "to ensure the possibility of transportation" (17). Like other modern machines, its own objectness and machinic resistance is dissolved as it becomes part of the "standing reserve", which can be understood as a macro-technology of provisioning through a matrix of mobilisable human and non-human resources. In the broader project of which this piece is a fragment, I want to investigate more closely the role and relative importance of machines compared to other kinds of equipment, especially for containment, supply or provisioning in contemporary technoculture, on the suspicion that it is apparatus and utilities rather than machines that define our contemporary lifeworld.

Introduction: Technology EnthusiasmEnthusiasts are people who have a passion, keenness, dedication or zeal for a particular activity or hobby. Today, there are enthusiasts for almost everything, from genealogy, costume dramas, and country houses, to metal detectors, coin collecting, and archaeology. But to be described as an enthusiast is not necessarily a compliment. Historically, the term “enthusiasm” was first used in England in the early seventeenth century to describe “religious or prophetic frenzy among the ancient Greeks” (Hanks, n.p.). This frenzy was ascribed to being possessed by spirits sent not only by God but also the devil. During this period, those who disobeyed the powers that be or claimed to have a message from God were considered to be enthusiasts (McLoughlin).Enthusiasm retained its religious connotations throughout the eighteenth century and was also used at this time to describe “the tendency within the population to be swept by crazes” (Mee 31). However, as part of the “rehabilitation of enthusiasm,” the emerging middle-classes adopted the word to characterise the intensity of Romantic poetry. The language of enthusiasm was then used to describe the “literary ideas of affect” and “a private feeling of religious warmth” (Mee 2 and 34). While the notion of enthusiasm was embraced here in a more optimistic sense, attempts to disassociate enthusiasm from crowd-inciting fanaticism were largely unsuccessful. As such enthusiasm has never quite managed to shake off its pejorative connotations.The 'enthusiasm' discussed in this paper is essentially a personal passion for technology. It forms part of a longer tradition of historical preservation in the United Kingdom and elsewhere in the world. From preserved railways to Victorian pumping stations, people have long been fascinated by the history of technology and engineering; manifesting their enthusiasm through their nostalgic longings and emotional attachment to its enduring material culture. Moreover, enthusiasts have been central to the collection, conservation, and preservation of this particular material record. Technology enthusiasm in this instance is about having a passion for the history and material record of technological development, specifically here industrial archaeology. Despite being a pastime much participated in, technology enthusiasm is relatively under-explored within the academic literature. For the most part, scholarship has tended to focus on the intended users, formal spaces, and official narratives of science and technology (Adas, Latour, Mellström, Oldenziel). In recent years attempts have been made to remedy this imbalance, with researchers from across the social sciences examining the position of hobbyists, tinkerers and amateurs in scientific and technical culture (Ellis and Waterton, Haring, Saarikoski, Takahashi). Work from historians of technology has focussed on the computer enthusiast; for example, Saarikoski’s work on the Finnish personal computer hobby:The definition of the computer enthusiast varies historically. Personal interest, pleasure and entertainment are the most significant factors defining computing as a hobby. Despite this, the hobby may also lead to acquiring useful knowledge, skills or experience of information technology. Most often the activity takes place outside working hours but can still have links to the development of professional expertise or the pursuit of studies. In many cases it takes place in the home environment. On the other hand, it is characteristically social, and the importance of friends, clubs and other communities is greatly emphasised.In common with a number of other studies relating to technical hobbies, for example Takahashi who argues tinkerers were behind the advent of the radio and television receiver, Saarikoski’s work focuses on the role these users played in shaping the technology in question. The enthusiasts encountered in this paper are important here not for their role in shaping the technology, but keeping technological heritage alive. As historian of technology Haring reminds us, “there exist alternative ways of using and relating to technology” (18). Furthermore, the sociological literature on audiences (Abercrombie and Longhurst, Ang), fans (Hills, Jenkins, Lewis, Sandvoss) and subcultures (Hall, Hebdige, Schouten and McAlexander) has also been extended in order to account for the enthusiast. In Abercrombie and Longhurst’s Audiences, the authors locate ‘the enthusiast’ and ‘the fan’ at opposing ends of a continuum of consumption defined by questions of specialisation of interest, social organisation of interest and material productivity. Fans are described as:skilled or competent in different modes of production and consumption; active in their interactions with texts and in their production of new texts; and communal in that they construct different communities based on their links to the programmes they like. (127 emphasis in original) Based on this definition, Abercrombie and Longhurst argue that fans and enthusiasts differ in three ways: (1) enthusiasts’ activities are not based around media images and stars in the way that fans’ activities are; (2) enthusiasts can be hypothesized to be relatively light media users, particularly perhaps broadcast media, though they may be heavy users of the specialist publications which are directed towards the enthusiasm itself; (3) the enthusiasm would appear to be rather more organised than the fan activity. (132) What is striking about this attempt to differentiate between the fan and the enthusiast is that it is based on supposition rather than the actual experience and observation of enthusiasm. It is here that the ethnographic account of enthusiasm presented in this paper and elsewhere, for example works by Dannefer on vintage car culture, Moorhouse on American hot-rodding and Fuller on modified-car culture in Australia, can shed light on the subject. My own ethnographic study of groups with a passion for telecommunications heritage, early British computers and industrial archaeology takes the discussion of “technology enthusiasm” further still. Through in-depth interviews, observation and textual analysis, I have examined in detail the formation of enthusiast societies and their membership, the importance of the material record to enthusiasts (particularly at home) and the enthusiastic practices of collecting and hoarding, as well as the figure of the technology enthusiast in the public space of the museum, namely the Science Museum in London (Geoghegan). In this paper, I explore the culture of enthusiasm for the industrial past through the example of the Greater London Industrial Archaeology Society (GLIAS). Focusing on industrial sites around London, GLIAS meet five or six times a year for field visits, walks and a treasure hunt. The committee maintain a website and produce a quarterly newsletter. The title of my paper, “If you can walk down the street and recognise the difference between cast iron and wrought iron, the world is altogether a better place,” comes from an interview I conducted with the co-founder and present chairman of GLIAS. He was telling me about his fascination with the materials of industrialisation. In fact, he said even concrete is sexy. Some call it a hobby; others call it a disease. But enthusiasm for industrial archaeology is, as several respondents have themselves identified, “as insidious in its side effects as any debilitating germ. It dictates your lifestyle, organises your activity and decides who your friends are” (Frow and Frow 177, Gillespie et al.). Through the figure of the industrial archaeology enthusiast, I discuss in this paper what it means to be enthusiastic. I begin by reflecting on the development of this specialist subject area. I go on to detail the formation of the Society in the late 1960s, before exploring the Society’s fieldwork methods and some of the other activities they now engage in. I raise questions of enthusiast and professional knowledge and practice, as well as consider the future of this particular enthusiasm.Defining Industrial ArchaeologyThe practice of 'industrial archaeology' is much contested. For a long time, enthusiasts and professional archaeologists have debated the meaning and use of the term (Palmer). On the one hand, there are those interested in the history, preservation, and recording of industrial sites. For example the grandfather figures of the subject, namely Kenneth Hudson and Angus Buchanan, who both published widely in the 1960s and 1970s in order to encourage publics to get involved in recording. Many members of GLIAS refer to the books of Hudson Industrial Archaeology: an Introduction and Buchanan Industrial Archaeology in Britain with their fine descriptions and photographs as integral to their early interest in the subject. On the other hand, there are those within the academic discipline of archaeology who consider the study of remains produced by the Industrial Revolution as too modern. Moreover, they find the activities of those calling themselves industrial archaeologists as lacking sufficient attention to the understanding of past human activity to justify the name. As a result, the definition of 'industrial archaeology' is problematic for both enthusiasts and professionals. Even the early advocates of professional industrial archaeology felt uneasy about the subject’s methods and practices. In 1973, Philip Riden (described by one GLIAS member as the angry young man of industrial archaeology), the then president of the Oxford University Archaeology Society, wrote a damning article in Antiquity, calling for the subject to “shed the amateur train drivers and others who are not part of archaeology” (215-216). He decried the “appallingly low standard of some of the work done under the name of ‘industrial archaeology’” (211). He felt that if enthusiasts did not attempt to maintain high technical standards, publish their work in journals or back up their fieldwork with documentary investigation or join their county archaeological societies then there was no value in the efforts of these amateurs. During this period, enthusiasts, academics, and professionals were divided. What was wrong with doing something for the pleasure it provides the participant?Although relations today between the so-called amateur (enthusiast) and professional archaeologies are less potent, some prejudice remains. Describing them as “barrow boys”, some enthusiasts suggest that what was once their much-loved pastime has been “hijacked” by professional archaeologists who, according to one respondent,are desperate to find subjects to get degrees in. So the whole thing has been hijacked by academia as it were. Traditional professional archaeologists in London at least are running head on into things that we have been doing for decades and they still don’t appreciate that this is what we do. A lot of assessments are handed out to professional archaeology teams who don’t necessarily have any knowledge of industrial archaeology. (James, GLIAS committee member)James went on to reveal that GLIAS receives numerous enquiries from professional archaeologists, developers and town planners asking what they know about particular sites across the city. Although the Society has compiled a detailed database covering some areas of London, it is by no means comprehensive. In addition, many active members often record and monitor sites in London for their own personal enjoyment. This leaves many questioning the need to publish their results for the gain of third parties. Canadian sociologist Stebbins discusses this situation in his research on “serious leisure”. He has worked extensively with amateur archaeologists in order to understand their approach to their leisure activity. He argues that amateurs are “neither dabblers who approach the activity with little commitment or seriousness, nor professionals who make a living from that activity” (55). Rather they pursue their chosen leisure activity to professional standards. A point echoed by Fine in his study of the cultures of mushrooming. But this is to get ahead of myself. How did GLIAS begin?GLIAS: The GroupThe 1960s have been described by respondents as a frantic period of “running around like headless chickens.” Enthusiasts of London’s industrial archaeology were witnessing incredible changes to the city’s industrial landscape. Individuals and groups like the Thames Basin Archaeology Observers Group were recording what they could. Dashing around London taking photos to capture London’s industrial legacy before it was lost forever. However the final straw for many, in London at least, was the proposed and subsequent demolition of the “Euston Arch”. The Doric portico at Euston Station was completed in 1838 and stood as a symbol to the glory of railway travel. Despite strong protests from amenity societies, this Victorian symbol of progress was finally pulled down by British Railways in 1962 in order to make way for what enthusiasts have called a “monstrous concrete box”.In response to these changes, GLIAS was founded in 1968 by two engineers and a locomotive driver over afternoon tea in a suburban living room in Woodford, North-East London. They held their first meeting one Sunday afternoon in December at the Science Museum in London and attracted over 130 people. Firing the imagination of potential members with an exhibition of photographs of the industrial landscape taken by Eric de Maré, GLIAS’s first meeting was a success. Bringing together like-minded people who are motivated and enthusiastic about the subject, GLIAS currently has over 600 members in the London area and beyond. This makes it the largest industrial archaeology society in the UK and perhaps Europe. Drawing some of its membership from a series of evening classes hosted by various members of the Society’s committee, GLIAS initially had a quasi-academic approach. Although some preferred the hands-on practical element and were more, as has been described by one respondent, “your free-range enthusiast”. The society has an active committee, produces a newsletter and journal, as well as runs regular events for members. However the Society is not simply about the study of London’s industrial heritage, over time the interest in industrial archaeology has developed for some members into long-term friendships. Sociability is central to organised leisure activities. It underpins and supports the performance of enthusiasm in groups and societies. For Fine, sociability does not always equal friendship, but it is the state from which people might become friends. Some GLIAS members have taken this one step further: there have even been a couple of marriages. Although not the subject of my paper, technical culture is heavily gendered. Industrial archaeology is a rare exception attracting a mixture of male and female participants, usually retired husband and wife teams.Doing Industrial Archaeology: GLIAS’s Method and PracticeIn what has been described as GLIAS’s heyday, namely the 1970s to early 1980s, fieldwork was fundamental to the Society’s activities. The Society’s approach to fieldwork during this period was much the same as the one described by champion of industrial archaeology Arthur Raistrick in 1973:photographing, measuring, describing, and so far as possible documenting buildings, engines, machinery, lines of communication, still or recently in use, providing a satisfactory record for the future before the object may become obsolete or be demolished. (13)In the early years of GLIAS and thanks to the committed efforts of two active Society members, recording parties were organised for extended lunch hours and weekends. The majority of this early fieldwork took place at the St Katherine Docks. The Docks were constructed in the 1820s by Thomas Telford. They became home to the world’s greatest concentration of portable wealth. Here GLIAS members learnt and employed practical (also professional) skills, such as measuring, triangulations and use of a “dumpy level”. For many members this was an incredibly exciting time. It was a chance to gain hands-on experience of industrial archaeology. Having been left derelict for many years, the Docks have since been redeveloped as part of the Docklands regeneration project.At this time the Society was also compiling data for what has become known to members as “The GLIAS Book”. The book was to have separate chapters on the various industrial histories of London with contributions from Society members about specific sites. Sadly the book’s editor died and the project lost impetus. Several years ago, the committee managed to digitise the data collected for the book and began to compile a database. However, the GLIAS database has been beset by problems. Firstly, there are often questions of consistency and coherence. There is a standard datasheet for recording industrial buildings – the Index Record for Industrial Sites. However, the quality of each record is different because of the experience level of the different authors. Some authors are automatically identified as good or expert record keepers. Secondly, getting access to the database in order to upload the information has proved difficult. As one of the respondents put it: “like all computer babies [the creator of the database], is finding it hard to give birth” (Sally, GLIAS member). As we have learnt enthusiasm is integral to movements such as industrial archaeology – public historian Raphael Samuel described them as the “invisible hands” of historical enquiry. Yet, it is this very enthusiasm that has the potential to jeopardise projects such as the GLIAS book. Although active in their recording practices, the GLIAS book saga reflects one of the challenges encountered by enthusiast groups and societies. In common with other researchers studying amenity societies, such as Ellis and Waterton’s work with amateur naturalists, unlike the world of work where people are paid to complete a task and are therefore meant to have a singular sense of purpose, the activities of an enthusiast group like GLIAS rely on the goodwill of their members to volunteer their time, energy and expertise. When this is lost for whatever reason, there is no requirement for any other member to take up that position. As such, levels of commitment vary between enthusiasts and can lead to the aforementioned difficulties, such as disputes between group members, the occasional miscommunication of ideas and an over-enthusiasm for some parts of the task in hand. On top of this, GLIAS and societies like it are confronted with changing health and safety policies and tightened security surrounding industrial sites. This has made the practical side of industrial archaeology increasingly difficult. As GLIAS member Bob explains:For me to go on site now I have to wear site boots and borrow a hard hat and a high visibility jacket. Now we used to do incredibly dangerous things in the seventies and nobody batted an eyelid. You know we were exploring derelict buildings, which you are virtually not allowed in now because the floor might give way. Again the world has changed a lot there. GLIAS: TodayGLIAS members continue to record sites across London. Some members are currently surveying the site chosen as the location of the Olympic Games in London in 2012 – the Lower Lea Valley. They describe their activities at this site as “rescue archaeology”. GLIAS members are working against the clock and some important structures have already been demolished. They only have time to complete a quick flash survey. Armed with the information they collated in previous years, GLIAS is currently in discussions with the developer to orchestrate a detailed recording of the site. It is important to note here that GLIAS members are less interested in campaigning for the preservation of a site or building, they appreciate that sites must change. Instead they want to ensure that large swathes of industrial London are not lost without a trace. Some members regard this as their public duty.Restricted by health and safety mandates and access disputes, GLIAS has had to adapt. The majority of practical recording sessions have given way to guided walks in the summer and public lectures in the winter. Some respondents have identified a difference between those members who call themselves “industrial archaeologists” and those who are just “ordinary members” of GLIAS. The walks are for those with a general interest, not serious members, and the talks are public lectures. Some audience researchers have used Bourdieu’s metaphor of “capital” to describe the experience, knowledge and skill required to be a fan, clubber or enthusiast. For Hills, fan status is built up through the demonstration of cultural capital: “where fans share a common interest while also competing over fan knowledge, access to the object of fandom, and status” (46). A clear membership hierarchy can be seen within GLIAS based on levels of experience, knowledge and practical skill.With a membership of over 600 and rising annually, the Society’s future is secure at present. However some of the more serious members, although retaining their membership, are pursuing their enthusiasm elsewhere: through break-away recording groups in London; active membership of other groups and societies, for example the national Association for Industrial Archaeology; as well as heading off to North Wales in the summer for practical, hands-on industrial archaeology in Snowdonia’s slate quarries – described in the Ffestiniog Railway Journal as the “annual convention of slate nutters.” ConclusionsGLIAS has changed since its foundation in the late 1960s. Its operation has been complicated by questions of health and safety, site access, an ageing membership, and the constant changes to London’s industrial archaeology. Previously rejected by professional industrial archaeology as “limited in skill and resources” (Riden), enthusiasts are now approached by professional archaeologists, developers, planners and even museums that are interested in engaging in knowledge exchange programmes. As a recent report from the British think-tank Demos has argued, enthusiasts or pro-ams – “amateurs who work to professional standards” (Leadbeater and Miller 12) – are integral to future innovation and creativity; for example computer pro-ams developed an operating system to rival Microsoft Windows. As such the specialist knowledge, skill and practice of these communities is of increasing interest to policymakers, practitioners, and business. So, the subject once described as “the ugly offspring of two parents that shouldn’t have been allowed to breed” (Hudson), the so-called “amateur” industrial archaeology offers enthusiasts and professionals alike alternative ways of knowing, seeing and being in the recent and contemporary past.Through the case study of GLIAS, I have described what it means to be enthusiastic about industrial archaeology. I have introduced a culture of collective and individual participation and friendship based on a mutual interest in and emotional attachment to industrial sites. As we have learnt in this paper, enthusiasm is about fun, pleasure and joy. The enthusiastic culture presented here advances themes such as passion in relation to less obvious communities of knowing, skilled practices, material artefacts and spaces of knowledge. Moreover, this paper has been about the affective narratives that are sometimes missing from academic accounts; overlooked for fear of sniggers at the back of a conference hall. Laughter and humour are a large part of what enthusiasm is. Enthusiastic cultures then are about the pleasure and joy experienced in doing things. Enthusiasm is clearly a potent force for active participation. I will leave the last word to GLIAS member John:One meaning of enthusiasm is as a form of possession, madness. Obsession perhaps rather than possession, which I think is entirely true. It is a pejorative term probably. The railway enthusiast. But an awful lot of energy goes into what they do and achieve. Enthusiasm to my mind is an essential ingredient. If you are not a person who can muster enthusiasm, it is very difficult, I think, to get anything out of it. On the basis of the more you put in the more you get out. In terms of what has happened with industrial archaeology in this country, I think, enthusiasm is a very important aspect of it. The movement needs people who can transmit that enthusiasm. ReferencesAbercrombie, N., and B. Longhurst. Audiences: A Sociological Theory of Performance and Imagination.

The is a general consensus that the Quality of Service (QoS) of Voice over Internet Protocol (VOIP) is of growing importance for research and study. In this dissertation we investigate the performance of VOIP and the impact of resource limitations in the performance of Access Networks. The impact of VOIP performance in access networks is particularly important in regions where Internet resources are limited and the cost of improving these resources is prohibitive. It is clear that perceived VOIP performance, as measured by mean opinion score in experiments where subjects are asked to rate communication quality, is determined by end to end delay on the communication path, delay variation, packet loss, echo, the coding algorithm in use and noise. These performance indicators can be measured and the contribution in the access network can be estimated. The relation between MOS and technical measurement is less well understood. We investigate the contribution of the access network to the overall performance of VOIP services and the ways in which access networks can be designed to improve VOIP performance. Issues of interest include the choice of coding rate, dynamic variation of coding rate, packet length, methods of controlling echo, and the use of Active Queue Management (AQM) in Access Network routers. Methods for analyzing the impact of the access network on VOIP performance will be surveyed and reviewed. Also, we consider some approaches for improving performance of VOIP by doing some experiment using NS2 simulation software with a view to gaining a better understanding of the design of access networks.

Of all of the desktop software available, that for the implementation of a database is some of the most complex. With the increasing number of computer users having access to this sophisticated software, but with no obvious way to learn the rudiments of data modelling for the implementation of a database, there is a need for a simple, convenient method to improve their understanding. The research described in this thesis represents the first steps in the development of a tool to accomplish this improvement. In a preliminary study using empirical research a conceptual model was used to improve novice end users’ understanding of the relational concepts of data organisation and the use of a database software package. The results showed that no conclusions could be drawn about either the artefact used or the method of evaluation. Following the lead of researchers in the fields of both education and information systems, a design research process was developed, consisting of the construction and evaluation of a training artefact. A combination of design research and a design experiment was used in the main study described in this thesis. New to research in information systems, design research is a methodology or set of analytical techniques and perspectives, and this was used to develop a process (development of an artefact) and a product (the artefact itself). The artefact, once developed, needed to be evaluated for its effectiveness, and this was done using a design experiment. The experiment involved exposing the artefact to a small group of end users in a realistic setting and defining a process for the evaluation of the artefact. The artefact was the tool that would facilitate the improvement of the understanding of data modelling, the vital precursor to the development of a database. The research was conducted among a group of novice end users who were exposed to the artefact, facilitated by an independent person. In order to assess whether there was any improvement in the novices’ understanding of relational data modelling and database concepts, they then completed a post-test. Results confirmed that the artefact, trialled through one iteration, was successful in improving the understanding of these novice end users in the area of data modelling. The combination of design research and design experiment as described above gave rise to a new methodology, called experimental design research at this early juncture. The successful outcome of this research will lead to further iterations of the design research methodology, leading in turn to the further development of the artefact which will be both useful and accessible to novice users of personal computers and database software. This research has made the following original contributions. Firstly, the use of the design research methodology for the development of the artefact, which proved successful in improving novice users’ understanding of relational data structures. Secondly, the novel use of a design experiment in an information systems project, which was used to evaluate the success of the artefact. And finally, the combination of the developed artefact followed by its successful evaluation using a design experiment resulted in the hybrid experimental design research methodology. The success of the implementation of the experimental design research methodology in this information systems project shows much promise for its successful application to similar projects.

Some hardware and software aspects of the transputer have been investigated. This involved two major areas of study. One was the development of inexpensive analog interfaces and the other was the development of an image processing system to identify carbon anode blocks used in the aluminum smelting process. The first part of this study looked at interfacing analog signals to the transputer via the transputer links. In particular, analog to digital and digital to analog converter boards, which were compatible to the industrial standard TRAM configuration, were designed and tested. The 8 bit single channel AID converter board developed was capable of handling a data rate of almost 200 thousand samples per second with a link speed of 20 Mbits/s. The multi-channel AID converter board was capable of sampling at 19.69 thousand samples per second per channel on eight channels, and the D/ A converter board was capable of handling a data throughput of 198.01 thousand conversions per second. The study illustrates that these maximum conversion rates are determined by the OCCAM software and not by the link speed. The second part of the study involved the development of a prototype image processing system to remotely identify carbon anodes. The software development for this was implemented in Turbo Pascal and OCCAM allowing a comparison to be made of the speed of these two implementations. The study details how the image processing techniques of connectivity analysis was applied to the pattern identification process. The use of sequential, concurrent and parallel processes in the implementation is discussed. The study showed that by using a fairly simple two dimensional pattern and a transputer for the processing, it would be possible to identify carbon anodes at several locations in a production plant within the time constraints of the production process.

Project investigates an intelligent decision support system on stock portfolio investment - the Portfolio Investment Decision Support System (PIDSS). There are a number of knowledge-based systems and decision support systems in the finance domain. Knowledge-based systems and decision support systems can also be combined in intelligent decision support systems, which result in more desirable features. In this research project, an intelligent decision support system on stock portfolio investment, the Portfolio Investment Decision Support System (PIDSS), was developed and evaluated. The main themes of investigation were: (i) the system architecture of an intelligent decision support system, (ii) the use of PIDSS as a learning tool, and (iii) comparison of PIDSS with other financial advising systems. PIDSS was developed under a Personal Computer Windows platform with Visual Basic and PROLOG. The domain expertise was stock portfolio investment, based on Modem Portfolio Theory and the Capital Asset Pricing Model. PIDSS was trialed with Finance students at Central Queensland University. Data was gathered using questionnaires and interviews. With its graphical representation and explanation facility, PIDSS was found to be helpful for students' learning. This was consistent with previous research in educational software. PIDSS also appeared to have potential to be further developed as a professional tool. A number of areas relating to functionality and system architecture efficiency were identified, however, as additional improvement.

Warehouse management is a significant element of a supply chain. The warehouse's data accuracy is the foundation of the whole supply chain material flow, information flow, and capital flow. It requires the warehouse receiving management to have an accurate system that operates in real-time to collect receiving data. However, conventional solutions for data management at the receiving stage are managed manually. Human involvement in the current receiving stage means that data accuracy and real-time entry cannot be assured. This research aims to improve data accuracy and reduce human error in the warehouse receiving management. The purpose of this research is to develop a suitable Artificial Neural Network (ANN) model by using machine learning technologies, which can be applied to warehouse receiving management to improve data accuracy and reduce human errors. Based on comprehensive literature review and analysis of current algorithms, a conceptual ANN model, identified as the Artificial Neural Network for Components Identification and Counting (ANN-CIC) model, is proposed to perform components classification and counting. This study has evaluated three classic image identification algorithms by using sixteen groups of industrial components to compare classification performance. A modified white histogram correlation coefficient approach is chosen as the design model's classification algorithm after experiments. Besides, the counting model is tested. The model is verified with an enlarged dataset obtained from a local Australian Company. The simulation results demonstrated that the proposed model achieved a 91.37% accuracy rate in object classification and a 94.29% in object counting, which has outperformed the existing classical model accuracy rate, such as for VGG-16. The main contributions of this research can be highlighted as below: Firstly, a conceptual ANN-CIC model is proposed to perform the identification and counting of industrial components. Four basic geometric shapes as the attributes of images for shape analysis and pre-defined features are introduced. These introduced shapes assisted in verifying the feasibility of the preliminary experiments. Secondly, the white histogram correlation coefficient algorithm is improved by adjusting the colour ratio to achieve outstanding performance in the classification of various industrial components. Lastly, the model is simulated with industrial data that demonstrates its applicability and stability. Moreover, higher classification and counting accuracy rate are achieved, and the design goal is also achieved.

This thesis explores the drivers that encourage small and medium enterprises (SMEs) in the hospitality industry in the Philippines to adopt information and communications technologies (ICTs) for their business operations during the 2020-21 COVID-19 pandemic. Despite having the distinction of being strategically located within the Asia-Pacific region, a bustling centre for world trade and commerce, an expansive melting pot of human resources and a prominent hub for agile technologies and innovations, Philippine SMEs are functioning below expectations in terms of their contribution to the country’s macroeconomy compared to other SMEs in the Asia-Pacific region. Literature highlights ICT adoption in SMEs can lead to improved business performance. Consequently, an examination of drivers or factors influencing ICT adoption in Philippine SMEs is now crucial. A systematic review of the literature on technology adoption in SMEs reveals only two studies from the Philippines out of a total of 185 studies done on the Asia-Pacific region. This clearly highlights the gap in research on SMEs in the Philippines. Further, SMEs throughout the world have been the hardest hit during the COVID-19 pandemic with huge losses and business closures. The hardest hit were the tourism and tourism-allied industries such as hospitality businesses, as governments around the world imposed lockdowns limiting travel and mobility to curtail the rapid spread of the disease. COVID-19 restrictions are likely to impact ICT adoption, and currently the published literature on ICT adoption during the pandemic in the hospitality sector SMEs is scarce. This thesis aims to address these identified research gaps in literature and develop an ICT adoption model for hospitality sector SMEs in the Philippines. Employing an exploratory sequential mixed-methods approach, this research commenced with 10 in-depth qualitative interviews with ICT implementation experts and experienced professionals working in the government and industry sectors. The findings of the qualitative study informed the design of the subsequent quantitative phase involving a survey of 154 SMEs in the hospitality industry in the Philippines. Results of the qualitative and quantitative phases were integrated to develop an ICT adoption model for Philippine SMEs. Findings of the mixed-method study revealed novel factors specific to the Philippines (e.g., Filipino culture, Philippine infrastructure and development, and local external change agents), and preparedness-related factors (i.e., perceived utility of ICTs for adapting to COVID-19, and perceived utility of ICTs for disaster preparedness) influencing ICT adoption in that country’s SMEs. These new insights were in addition to factors already identified in the literature on the technology, organisation and environment or the TOE model devised by Tornatzky, Fleischer and Chakrabarti (1990). This thesis reports 16 significant drivers for ICT adoption in Philippine SMEs, namely: technological (relative advantage, perceived ease of use, and cost of the technology), organisational (top management support, resources, awareness, attitude and end user skill ), environmental (market forces, service providers’ competence and support, government intervention, and social or external pressure), Philippine-specific (Philippine infrastructure and development, and local external change agents) and preparedness-related (perceived utility of ICTs for adapting to COVID-19, and perceived utility of ICTs for disaster preparedness). The findings suggest it is necessary and urgent for ICT developers to produce solutions that not only benefit SMEs but also not costly to the extent that they will not be able to maximise their benefits such as adapting to COVID-19 and natural calamities. Further, the government and other change agents have important roles to play in terms of improving the infrastructure needed for interconnectivity, increasing awareness of the relative advantage of ICTs in business and developing end-user skills through training and education.

This dissertation contextualises the forensic computing domain in terms of validation of tools and processes. It explores the current state of forensic computing comparing it to the traditional forensic sciences. The research then develops a classification system for the disciplines functions to establish the extensible base for which a validation system is developed.

Digital forensic investigators have a duty to understand the relevant components of the cases that they work. However, with the constant evolution of technologies, and the release of new platforms and programs, it is impossible for an investigator to be familiar with every application they encounter. It can also be difficult to know how forensic tools handle certain applications. This is why forensic researchers study and document new and emerging technologies, platforms, and applications, so that investigators have resources to utilize whenever they encounter an unfamiliar element in a case.

This research includes an examination and analysis of the phenomenon of database slack.
Database forensics is an underexplored subfield of Digital Forensics, and the lack of research is
becoming more important with every breach and theft of data. A small amount of research exists
in the literature regarding database slack. This exploratory work examined what partial records of
forensic significance can be found in database slack. A series of experiments performed update
and delete transactions upon data in a PostgreSQL database, which created database slack.
Patterns of hexadecimal indicators for database slack in the file system were found and analyzed.
Despite limitations in the experiments, the results indicated that partial records of forensic
significance are found in database slack. Significantly, partial records found in database slack
may aid a forensic investigation of a database breach. The details of the hexadecimal patterns of
the database slack fill in gaps in the literature, the impact of log findings on an investigation was
shown, and complexity aspects back up existing parts of database forensics research. This
research helped to lessen the dearth of work in the area of database forensics as well as database slack.

In the late 1960s, a new type of information system came about: model-oriented DSS or management decision systems. By the late 1970s, a number of researchers and companies had developed interactive information systems that used data and models to help managers analyze semistructured problems. These diverse systems were all called decision support systems (DSS). From those early days, it was recognized that DSS could be designed to support decision-makers at any level in an organization. DSS could support operations, financial management, and strategic decision making. Group decision support systems (GDSS) which aim at increasing some of the benefits of collaboration and reducing the inherent losses are interactive information technology-based environments that support concerted and coordinated group efforts toward completion of joint tasks (Dennis, George, Jessup, Nunamaker, & Vogel, 1998). The term group support systems (GSS) was coined at the start of the 1990s to replace the term GDSS. The reason for this is that the role of collaborative computing was expanded to more than just supporting decision making (Patrick & Garrick, 2006). For the avoidance of any ambiguities, the latter term shall be used in the discussion throughout this article. Human resources (HR) are rarely expected like other business functional areas to use synthesized data because HR groups have been primarily connected with transactional processing of getting data into the system and on record for reporting and historical purposes (Dudley, 2007). For them soft data do not win at the table; hard data do. Recently, many quantitative or qualitative techniques have been developed to support human resource management (HRM) activities, classified as management sciences/operations research, multiattribute utility theory, multicriteria decision making, ad hoc approaches, and human resource information systems (HRIS) (Byun, 2003). More importantly, HRIS can include the three systems of expert systems (ES), decision support systems (DSS), and executive information systems (EIS) in addition to transaction processing systems (TPS) and management information systems (MIS) which are conventionally accepted as an HRIS. As decision support systems, GSS are able to facilitate HR groups to gauge users’ opinions, readiness, satisfaction, and so forth, increase their HRM activity quality, and generate better group collaborations and decision makings with current or planned HRIS services. Consequently, GSS can help HR professionals exploit and make intelligent use of soft data and act tough in their decision-making process.
