The Engineering discipline has relied on computers to perform numerical calculations in many of its sub-disciplines over the last decades. The advent of graphical processing units (GPUs), parallel stream processors, has the potential to speed up generic simulations that facilitate engineering applications aside from traditional computer graphics applications, using GPGPU (general purpose programming on the GPU). The potential benefits of exploiting the GPU for general purpose computation require the program to be highly arithmetic intensive and also data independent. This paper looks at the specific application of the Conjugate Gradient method used in hydraulic network solvers on the GPU and compares the results to conventional central processing unit (CPU) implementations. The results indicate that the GPU becomes more efficient as the data set size increases. However, with the current hardware and the implementation of the Conjugate Gradient algorithm, the application of stream processing to hydraulic network solvers is only faster and more efficient for exceptionally large water distribution models, which are seldom found in practice.

Church, Dan M. "On the Use of Carrots and Sticks in CALL". CALICO Journal 6, n. 1 (14 gennaio 2013): 37–45. http://dx.doi.org/10.1558/cj.v6i1.37-45.

Desire to learn a second language or excitement designed into the program is seldom sufficient for long-term motivation for students to use CALL programs as much as needed. Programs need to be not only closely correlated to the goals and methods of the course but also required and graded in order for students to use them conscientiously and beneficially. Development and modification of CALL use in an elementary course over a period of years allows us to draw some conclusions about how requirements and grades can serve as carrots and sticks to motivate students to use the CALL programs. We can also see some ways in which such requirements and grades can be made to seem more like carrots and less like sticks.

The field of African language CALL is expanding rapidly as part of the general trend toward foreign language CALL. Yet the assumptions and needs of the learner in such instruction are quite different from that of the more commonly taught languages. African language instruction may not always be classroom-oriented: texts are seldom available for most of the uncommonly taught languages, and a native speaker as consultant may or may not have training in foreign language instruction. These factors have led to the need for self-standing, computer-driven instruction for these languages. This paper will discuss some assumptions regarding generative-based African language CALL, with references to Bantu languages and to one particular language (the OluTsootso dialect of Luyai, a language of Kenya), and describe elements of a computer program that produces superficial forms from underlying forms of that language. The paper will close with a discussion of some of the differences between computer characterizations of certain phonological phenomena and the generative linguist's description of such phenomena.

Image recognition and classification were put in used in many places in recent years thanks to the great progress in machine learning and neural networks. However, seldom evidence indicate applications of image recognition in computer games. Since games are gradually becoming part of peoples life, it is the time to put the focus on those who are unable to enjoy this entertainment. Nowadays computer games often include the element of collecting e.g. (materials or treasure). A program that could automatically mark those collectable objects would significantly improve the gaming experience for those who have disability in their eyes. In this work the game Destiny 2 was used for training and testing and training model chose was Yolov5. 1,500 of images were put into the data set and trained with 350 epochs. The model eventually achieved 0.82 in precision, 0.96 in recall and 0.91 in F1. It also gets the average mAP value of 0.93. These results can strongly prove that this model has the potential to be used in real scenarios.

This study assessed the office competencies and challenges among the newly appointed Barangay Secretaries of Local Government Unit (LGU) of Nabua in Camarines Sur, Bicol Region in the Philippines. This descriptive method of research used questionnaire and interview using the percentage method and mean as its statistical tools using the four-scale rating to interpret the gathered data. The actual respondents of the study were the 35 of the 45 Barangay Secretaries of LGU-Nabua. Findings reveal that the office competencies of barangay secretaries along stenography, office management, records management, and human relations were all assessed as satisfactory except for computer operation which was assessed as fair. The study further revealed that challenges were seldom encountered by the respondents along their work performance. Majority of the respondents preferred training program on records management and office management but computer operation in varied software with ease may also be given emphasis. Recommendations to enhance the office competencies and address the challenges encountered by barangay secretaries in their present job were also proposed in this study.

Introduction: Linear boundary value problems for Fredholm ordinary integro-differential equations are seldom consideredwith integral boundary conditions in the literature. In our case, integro-differential equations are subject to multipoint or nonlocalintegral boundary conditions. It should be noted that finding exact solutions even for multipoint problems or problems with nonlocalintegral boundary conditions with a differential equation is a difficult task. Purpose: Finding the uniqueness and existencecriterion of solutions for Fredholm ordinary integro-differential equations with multipoint or nonlocal integral boundary conditionsand obtaining exact solutions in closed form of such problems. Results: Within the class of abstract operator equations, for thespecial case of Fredholm integro-differential equations with multipoint or nonlocal integral boundary conditions, a criterion for theexistence and uniqueness of an exact solution is proved and the analytical representation of the solution is given. A direct methodanalytically solving such problems is proposed, in which all calculations are reproducible in any program of symbolic calculations.If the user sets the input parameters and the initial conditions of the problem, the computer codes check the conditions of existenceand uniqueness and of solution generate the analytical solution. The stages of the solution method are illustrated by twoexamples. The article uses computer algebra system Mathematica to demonstrate the results.

Abstract Primary and secondary clarifiers seldom operate with constant hydraulic and solids loading; in many plants there are significant diurnal variations in flows and solids loads. Secondary clarifiers are subject to density currents due to the relatively high concentrations of suspended solids in the influent. In this study a computer program for unsteady flow in a centre-fed circular clarifier was used to predict the effects of unsteady flow on the clarifier performance. Two cases were considered, namely: diurnal variation in flow at a constant MLSS concentration and a sudden increase in the MLSS. In both cases, the results of the model simulations indicated that clarifier performance is significantly affected by the unsteadiness of the flow; a steady state analysis at the peak flow gave lower effluent concentrations than either the diurnal flow or the step increase in the MLSS. The model simulations suggested that this effect was greater for peripheral weirs than in-board launders.

This research paper conducts a Critical Discourse Analysis of the Instagram campaign run by WeAreHERe, a peer-to-peer mentorship program designed for women high school students and first-year university students at Politecnico di Torino. The study scrutinizes 92 posts shared on the WeAreHERe Instagram page during the academic year 2021-2022. The primary goal of the research is, first, to bridge an existing gap in the literature by connecting studies on stereotypes, biases, and mentorship as a constructive means to promote women’s role models with research on gender-based structural oppression. Secondly, this study aims to enhance the WeAreHERe campaign through a comprehensive analysis, ultimately providing insights for shaping future policies about mentorship programs for female students in STEM fields. The analysis showed that most of the posts focus on the individual level rather than on structural oppression and the role models they depict are presented as relatable rather than unique humans. Even when the motivational posts acknowledge the existence of a gender-oppressive structure they seldom mention it clearly, failing to uncover the generative link between this structure of oppression and gender biases and stereotypes. The results show that the literature on stereotypes and biases could be enriched by an approach focused on structural oppression. From these results we developed some guidelines that could help the WeAreHERe campaign – and other similar campaigns that aims at fighting stereotypes about women in the STEM field – to tackle issues of systematic oppression. The use of role models is more effective when it highlights systematic oppression and favours the creation of communities that would help bringing systematic change.

The article concerns the current problem of organizing students’ independent work in foreign languages by applying different innovative approaches. The article aims to study and try different pedagogical technologies and teaching methods widely used in the classroom but seldom applicable within independent students’ learning and cognitive activity. The authors give reasons for integrating new pedagogical methods and technologies in learning experiences and their advantages over the traditional approaches. Practical experience in the field of using different modern pedagogical methods and technologies while organizing students’ independent work is presented. The authors describe educational potential of Internet network resources, computer programs and mobile applications, using them in students’ independent work helps solve multiple tasks such as to expand vocabulary, to overcome difficulties in grammar, to reinforce pronunciation, auditive and grammatical skills. Moreover, tests accessible in the Internet can be used as assessment materials. The capabilities of gamification include such instruments as network services, computer games or interactive presentations working on-line as well as off-line. The article presents the results of using web-quest technology, its advantages over traditional forms of work in developing different language activities. Project method is also successfully used in practice for organizing independent students’ learning activity. The article stresses that innovative approaches make possible to prepare tasks that have true interdisciplinary nature and promote professional and scientific personal enrichment of students. Presented in the article experience of organizing students’ independent work can be used in non-linguistic educational establishments for the purpose of enhancing students’ independent learning of foreign languages.

Indigenous cattle in Indonesia seldom to reach their genetic potentials due to an interaction impact of harsh tropical climate and low-quality feed. Some indigenous breeds of cattle in Indonesia, such as Bali, Madura and Crossbred Ongole have demonstrated their successful adaptation to survive in the harsh environment, but their ultimate performances are still considered less than their genetic potentials when reared under comfortable environment like in the sub-tropical climate. This is primarily due to inefficient fermentation of feed originating from inadequate supply of essential nutrients required for optimum growth of microbes in the forestomach. A rapid advancement of omics technology has been the driver for ruminant nutritionists to use such a technology to study the interrelationship between nutrients and particular genes associated with the biochemical pathways of nutrients at molecular levels. This review highlights the current issues and challenges on the use of omics technologies to improve the efficiency of feed utilization by cattle consuming low-quality diets and its potential to be used in the genetic selection program.

Testo completoAbstract (sommario):
Computing systems are everywhere today. Even the brain is thought to be a sort of computing system. But what does it mean to say that a given organ or system computes? What is it about laptops, smartphones, and nervous systems that they are deemed to compute, and why does it seldom occur to us to describe stomachs, hurricanes, rocks, or chairs that way? The book provides an extended argument for the semantic view of computation, which states that semantic properties are involved in the nature of computing systems. Laptops, smartphones, and nervous systems compute because they are accompanied by representations. Stomachs, hurricanes, and rocks, for instance, which do not have semantic properties, do not compute. The first part of the book argues that the linkage between the mathematical theory of computability and the notion of physical computation is weak. Theoretical notions such as algorithms, effective procedure, program, and automaton play only a minor role in identifying physical computation. The second part of the book reviews three influential accounts of physical computation and argues that while none of these accounts is satisfactory, each of them highlights certain key features of physical computation. The final part of the book develops and argues for a semantic account of physical computation and offers a characterization of computational explanations.

Testo completoAbstract (sommario):
Millions of people have listened to John H. Lienhard's radio program "The Engines of Our Ingenuity." In this fascinating book, Lienhard gathers his reflections on the nature of technology, culture, and human inventiveness. The book brims with insightful observations. Lienhard writes that the history of technology is a history of us--we are the machines we create. Thus farming dramatically changed the rhythms of human life and redirected history. War seldom fuels invention--radar, jets, and the digital computer all emerged before World War II began. And the medieval Church was a driving force behind the growth of Western technology--Cistercian monasteries were virtual factories, whose water wheels cut wood, forged iron, and crushed olives. Lienhard illustrates his themes through inventors, mathematicians, and engineers--with stories of the canoe, the DC-3, the Hoover Dam, the diode, and the sewing machine. We gain new insight as to who we are, through the familiar machines and technologies that are central to our lives.

At the Massachusetts Institute of Technology in the 1950s, some of the brightest students seldom attended classes. Instead they loitered around the Tech Model Railroad Club. The most brilliant were tapped to join the Signals and Power Committee, which rigged ever more elaborate systems of programmable track switches using nothing more sophisticated than telephone relays. Taking pride in their ad hoc wiring, which ignored all conventions of electrical engineering, they referred to themselves as hackers. Nothing was impossible for them; nothing was off limits. When MIT acquired its first computer in 1956, they infiltrated the control room, where they coerced the electronics to do tricks unintended by the manufacturer, using sine and cosine routines to code the first digital computer game. As computers became more common, so did hacking. To program home computers in the 1970s no longer required the imaginative genius of the MIT Signals and Power Committee, and by the 1980s self-professed hackers ranged from professional software developers to adolescent cyberpunks. The latter proved considerably more interesting to the public, riveted by their ability to torment corporations and governments from their bedrooms. “A hacker—computer jargon for an electronic eavesdropper who by-passes computer security systems—yesterday penetrated a confidential British Telecom message system being demonstrated live on BBC-TV,” reported the Daily Telegraph in a typical news story of 1983, the year that War Games hit the big screen. Old-school Signals and Power hackers fought valiantly against this linguistic turn, insisting that the young punks were crackers rather than hackers, but the media ignored the distinction, leading most new-school professionals to head off confusion by blandly presenting themselves as computer scientists or software engineers or information technology specialists. Aside from the occasional insider reference—ITs who troubleshoot security systems were sometimes known as “white-hat” hackers— the criminal connotation seemed permanent. Then in 2004 a Silicon Valley technology writer named Danny O’Brien gave a forty-five-minute lecture at the O’Reilly Emerging Technology Conference titled “Life Hacks: Tech Secrets of Overprolific Alpha Geeks.” Within a year technophiles worldwide, from computer scientists to iPhone addicts, were striving to become hackers again.

Testo completoAbstract (sommario):
The nuclear waste programs of the United States and other countries have forced geologists to think specifically about probabilities of natural events, because the legal requirements to license repositories mandate a probabilistic standard (US EPA, 1985). In addition, uncertainties associated with these probabilities and the predicted performance of a geologic repository must be stated clearly in quantitative terms, as far as possible. Geoscientists rarely have thought in terms of stochasticity or clearly stated uncertainties for their results. All scientists are taught to acknowledge uncertainty and to specify the quantitative uncertainty in each derived or measured value, but this has seldom been done in geology. Thus, the nuclear waste disposal program is forcing us to do now what we should have been doing all along: acknowledge in quantitative terms what uncertainty is associated with each quantity that is employed, whether deterministically or probabilistically. Uncertainty is a simple concept ostensibly understood to mean that which is indeterminate, not certain, containing doubt, indefinite, problematical, not reliable, or dubious. However, uncertainty in a scientific sense demonstrates a complexity which often is unappreciated. Some types of uncertainty are difficult to handle, if they must be quantified, and a completely satisfactory treatment may be impossible. Initially, only uncertainty associated with measurement, was quantified. The Gaussian, or normal, probability density function (pdf) was recognized by Carl Friedrich Gauss as he studied errors in his measurements two centuries ago and developed a theory of errors still being used today. This was the only type of uncertainty that scientists acknowledged until Heisenberg stated his famous uncertainty principle in 1928. As information theory evolved during and after World War II, major advances were made in semantic uncertainty. Today, two major types of uncertainty are generally recognized (Klir and Folger, 1988): ambiguity or nonspecificity and vagueness or fuzziness. These can be subdivided further into seven types having various measures of uncertainty based on probability theory, set theory, fuzzy-set theory, and possibility theory.

Testo completoAbstract (sommario):
Hepatocellular carcinoma arises commonly on the background of liver cirrhosis. Patients presenting with clinical symptoms have advanced stage and often are unsuitable for curative therapies. Diagnosis of hepatocellular carcinoma is commonly performed by multiphase computed tomography (CT) and / or magnetic resonance imag¬ing scans (MRI). Contrast enhanced ultrasound and MRI with hepatobiliary contrast agents are better in characterizing small lesions. Tumor markers play an adjunct role in diagnosis. For HCC in cirrhotic liver biopsy is seldom required and diagnosis is based on typical imaging features of non-rim arterial phase hyperenhancement and washout on delayed phase and pseudocapsule appearance. This is due to differential blood supply of liver parenchyma, regenerative nodules and tumor. Biopsy is only required in noncirrhotic liver, vascular liver diseases, atypical imaging features. Surveillance programs involving high risk groups can help in early detection of lesions which are amenable for curative therapies. Biannual ultrasound with or without alfa fetoprotein are commonly used surveillance tests. Multidisciplinary teams provide platform for care coordination, reassessments of clinical course, and fine changes in treatment plans required for management of this complex group of patients.

Mountain, Jeffrey R. "The Decline of Design Across the Curriculum". In ASME 2008 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference. ASMEDC, 2008. http://dx.doi.org/10.1115/detc2008-49806.
Testo completoAbstract (sommario):
Design across the curriculum has been a cornerstone of mechanical engineering education for well over a decade. The movement was an attempt to balance the tendency of most programs to over-emphasize engineering science. Over the course of that decade, many public universities have undergone a 7%–10% reduction in the number of credits required for graduation; usually in response to legislative pressure or competitive market conditions. In some instances, these reductions were not reflected in the general education content. Although the number of technical electives within the curriculum may have been reduced, seldom have they been completely omitted. Engineering science is considered the analytical foundation upon which new knowledge and engineering design are based. In addition, new frontiers in mechatronics, nanotechnology and alternative energy sources are becoming “must teach” subjects so that the discipline can evolve. The indication is that the “Design Across the Curriculum” concept either is, or will soon be in decline. This paper will present some historical perspective, a small sample of both common “solutions,” and a few unique approaches for maintaining design across the curriculum. The primary objective, however, is to initiate a dialog among engineering educators to begin to address the balance between engineering science and engineering design.
