Abstract:

Laminar flow correlations for f and Num are developed based on experimental data for water and ethylene glycol, with tape inserts of three different twist ratios. The uniform wall temperature condition is considered, which typifies practical heat exchangers in the chemical and process industry. These and other available data are analyzed to devise flow regime maps that characterize twisted-tape effects in terms of the dominant enhancement mechanisms. Depending upon flow rates and tape geometry, the enhancement in heat transfer is due to the tube partitioning and flow blockage, longer flow path, and secondary fluid circulation; fin effects are found to be negligible in snug- to loose-fitting tapes. The onset of swirl flow and its intensity is determined by a swirl parameter, Sw=Resw/y, that defines the interaction between viscous, convective inertia, and centrifugal forces. Buoyancy-driven free convection that comes into play at low flow rates with large y and ΔTw is shown to scale as Gr/Sw2≫ 1. These parameters, along with numerical baseline solutions for laminar flows with y = ∞, are incorporated into correlations for f and Num by matching the appropriate asymptotic behavior. The correlations describe the experimental data within ±10 to 15 percent, and their generalized applicability is verified by the comparison of predictions with previously published data.

Abstract:

Firms need to assess the competitive advantage by determining the strategic advantages. TDABC is an instrument to achieve operational improvements in practice, reducing non value added activities and merge similar activities into one place. The objectives of this research is to calculate using the time driven activity based costing ( TDABC ) method on Tape Handayani 82 Small and Medium Enterprises ( SMEs ) in Bondowoso Regency. This study is a qualitative research. Design of qualitative methods is general, flexible, and thrives in the process of research. Researchers involve directly in order obtaining as much information. One focus of qualitative research is a phenomenon that can only be explained and cannot be measured, and the phenomenon observed by researchers in the field. Object of study is the Tape Handayani 82 SME that engaged in tape industry. Selections of the research object because tape is typical of the Bondowoso. Tape has relatively high market share, but in efficiency of time management, activities undertaken, not in accordance with time -driven activity-based costing concepts. Data collection methods used in this qualitative approach. This step is done by directly observe and conduct interviews with employer and owner who do day-to- day business activities especially financial. Recognition of cost of tape products show too low. As for the fuel smoked tape, tape, dodol and suwar suwir show the company recognize higher. Calculations with TDABC provide more accurate information related to the consumption cost. The result can be used to revise cost product. Added analysis of the activities does by identifying, preparing and evaluating activities description. The analysis identifies what activities are done, how many people who carry out these activities, the time and resources necessary to do the activity. TDABC analysis indicates that Tape 82 Handayani is not efficient yet. 70 % is still idle capacity so it is necessary to create added value activity. Idle capacity led to increased costs or consumes resources costs that are not necessary. Keywords: TDABC, activity, poduct cost, tape

Abstract:

Metallic alloy thin film media and ever decreasing head-to-media spacing make severe demands on storage devices. Decreasing head-to-media separation is critical for high storage densities but it also leads to increased slider-disk interactions, which can cause slider and disk wear or even head crashes. Wear can also occur when drives start and stop when the slider contacts the disk at relatively high speeds. The reliability and durability of thin film disks, which provide much higher areal density than conventional oxide disks with particulate media, are achieved by the use of very thin overcoat materials and surface lubricants. This article summarizes the approaches taken in the industry to enhance the tribological performance of magnetic media, with special emphasis on the basic understanding of the processes occurring at the slider-disk interface.The continuous rise in the demand for storage capacity at a competitive price is the prime motivator of the changes we have seen in the data storage industry. It is clearly stimulating the present move away from particulate media, which has long dominated all fields of data storage, i.e., tape, rigid, and flexible disks, to the thin film storage media. Particulate storage devices use magnetic media formulated by dispersing magnetic particles, usually iron oxides, in an organic binder. In thin film storage devices, the storage medium is a continuous magnetic film, usually a cobalt alloy, made either by sputtering or by electroless plating.

Abstract:

Purpose The purpose of this paper is to examine the impact of institutional environment on the international performance of small- and medium-sized enterprises (SMEs) and how this relationship is influenced by network competence. Design/methodology/approach This study uses a quantitative approach. In total, 119 internationally operating Finnish SMEs from five industry sectors are sampled via a cross-sectional survey. Data are analysed through regression modelling. Findings The international performance of SMEs is influenced directly and indirectly by institutional drivers. The results show that network competence mediates the positive relationship between institutional drivers and international performance. Research limitations/implications Network capability development can help SMEs leverage more or less favourable institutional environments for successful internationalisation. Perceived institutional drivers directly result in higher performance, but the effect can be partially mediated by dynamic capabilities. The limitations of the study include its single-country context and the cross-sectional nature of the data. Practical implications SMEs should take their home countries’ institutional environments into account, but for long-term success, they should develop the ability to manage their business networks. A conducive institutional environment may help develop competence, which in turn can enable more successful internationalisation in terms of scale, scope and satisfaction. Social implications Decision-makers may benefit from knowing that, in addition to capabilities, an institutionally conducive environment that drives domestic SMEs towards international markets may be an antecedent of successful internationalisation in the SME sector. Originality/value This is one of the few studies to illustrate how network capabilities can mediate the influence of institutional factors on entrepreneurial internationalisation. It combines institutional theory and the dynamic capabilities view to explain successful SME internationalisation.

Abstract:

India announced its first National Telecom Policy in 1994 and since then its telecommunications Industry has witnessed tremendous growth. At a teledensity of 89.92% (TRAI 2019), it is the second largest telecom market in the world. The policy maker, Department of Telecommunication (DoT) and the regulator, Telecom Regulatory Authority of India (TRAI) have taken several initiatives to ensure affordable services to telecom users. TRAI also drives initiatives to increase the level of awareness about telecom industry among users. To analyse impact of these initiatives by TRAI and DoT, this study presents an objective assessment of user's awareness and their assessment of affordability of telecom services. A structured questionnaire is used to collect data by surveying a sample of 408 telecom users. It was found that half of the respondents were aware of DoT; more than half were aware of the regulator TRAI and Indian governments vision for telecommunications and 85% of survey respondents found telecom services affordable. The level of affordability varied across gender, age group and education levels. Through regression analysis, the study found that awareness about telecom industry influences users' assessment of service affordability. Hence, TRAI and DoT should take actions to increase the level of awareness, which will improve users' perception of affordability and may lead to increased adoption of telecom services. In addition, it is suggested that affordability of female users can be addressed through customized tariff plan and schemes.

Abstract:

This study aims to describe local specialties that have the potential to become halal food in order to boost the economy of local communities in three areas including Lakbok sub-district, Kedungreja sub-district, and Wangon sub-district. In the halal food sector or halal food in Indonesia, especially in the Era of the Industrial Revolution 4.0, as it is now, it has become a necessity. This is because 1) Indonesia is one of the largest Muslim population in the world. 2) traditional regional specialties also need to be developed in order to boost the economy of the local community. 3) Support from the government in an effort to make Indonesia the world's halal center. 4) If the potential of the halal industry is not developed, it will become a threat to the Indonesian economy. This research method uses field studies with data obtained from observations and interviews and documentation. The results showed that halal food in the three sub-districts was able to boost the economy of the people in the area, as evidenced by the sufficient daily needs needed by the people in the three sub-districts. Various foods that can be used as halal food in these three sub-districts are varied, including cassava based chips, Tape, Cimplung or Kulub and Ciu, from soybean ingredients including Sule and Tempe Mendoan, from legen ingredients (coconut juice) can be made into Javanese sugar / brown sugar and can also be used as a mixture for making apem / cake foods. However, from the potential of halal food, some are already labeled halal and some are not labeled halal. This is what makes halal food in these three sub-districts less attractive to consumers. Penelitian ini bertujuan untuk mendeskripsikan makanan khas lokal daerah yang berpotensi menjadi makanan halal (halal food) guna mendongkrak perekonomian masyarakat daerah yang berada di tiga wilayah meliputi kecamatan Lakbok, kecamatan Kedungreja, dan kecamatan Wangon. Dalam sektor makanan halal atau halal food di Indonesia khususnya di Era Revolusi Industri 4.0 seperti sekarang ini telah menjadi sebuah keniscayaan. Hal ini dikarenakan 1) Indonesia masuk pada penduduk muslim terbesar di Dunia. 2) makan tradisional khas daerah juga perlu dikembangkan dalam rangka mendongkrak perekonomian masyarakat setempat. 3) Dukungan dari pemerintah dalam usaha menjadikan Indonesia sebagai pusat halal dunia. 4) Jika potensi industri halal ini tidak dikembangkan maka justru menjadi ancaman bagi perekonomian Indonesia. Metode penelitian ini menggunakan studi lapangan dengan data yang diperoleh dari hasil observasi dan wawancara serta dokumentasi. Hasil penelitian menunjukan bahwa halal food di tiga kecamatan tersebut mampu mendogkrak perekonomian masyarakat di wilayah tersebut, dibuktikan dengan cukupnya kebutuhan sehari-hari yang diperlukan oleh masyarakat di tiga kecamatan tersebut. Aneka makanan yang dapat dijadikan sebagai halal food di tiga kecamatan ini beragam, diantaranya dari berbahan singkong adalah Kripik, Tape, Cimplung atau Kulub dan Ciu, dari bahan kedelai meliputi Sule dan Tempe Mendoan, dari bahan legen (air nira kelapa) dapat dijadikan buat menjadi gula jawa / gula merah dan dapat juga dijadikan sebagai campuran pembuatan makanan apem/kue. Namun dari potensi halal food tersebut ada yang sudah berlabel halal dan juga ada yang belum berlabel halal. Inilah yang menjadikan halal food ditiga kecamatan tersebut kurang diminati oleh konsumennya.

Abstract:

Tape is an excellent choice for archival storage because of the capacity, cost per GB and long retention intervals, but its main drawback is the slow access time due to the nature of sequential medium. Modern enterprise tape drives now support Recommended Access Ordering (RAO), which is designed to reduce data recall/retrieval times. BNL SDCC's mass storage system currently holds more than 100 PB of data on tapes, managed by HPSS. Starting with HPSS version 7.5.1, a new feature called “Tape Order Recall (TOR) has been introduced. It supports both RAO and non-RAO drives. The file access performance can be increased by 30% to 60% over the random file access. Prior to HPSS 7.5.1, we have been using an in-house developed scheduling software, aka ERADAT. ERADAT accesses files based on the file logical position order. It has demonstrated a great performance over the past decade long usage in BNL. In this paper we will present a series of test results, compare TOR and ERADAT's performance under different configurations to show how effective TOR (RAO) and ERADAT perform and what is the best solution in data recall from SDCC's tape storage

Abstract:

AbstractBy the end of 2006, the areal density of magnetic recording on tape will approach that seen in hard disk drives of the early to mid-1990s.These operating conditions are reviewed in relation to the operating conditions deemed necessary for the future of magnetic data storage on tape.What results is a clear set of tasks, encompassing both materials and systems architecture issues, to achieve very high-density data storage on magnetic tape, leading to 10 Tbyte tape cartridge capacities and higher.The key to achieving on tape the areal densities of tens to hundreds of Gbit in.2, common in hard disk drives (HDDs), lies primarily in the properties of the medium itself.As for volumetric density of the storage entity, HDDs and tape cartridges are roughly equivalent.The mechanical dimensional uncertainties that accompany the use of flexible, as opposed to rigid, media means that both the mechanical and magnetic properties of materials play a key role in the future of tape.The need for new architectures to overcome the track placement problem that results from increasing track density on flexible media are reviewed, as well as the “particles in a binder” concept that has served so well as the physical basis of tape media over the past 50 years.

Abstract:

Magnetic tape remains the medium of choice for long-term data storage at the lowest possible cost. Moreover, tape-cartridge capacities are expected to maintain a compound annual growth rate of about 40%, resulting in a 128 TByte tape-cartridge capacity by 2022, as forecast by the Information Storage Industry Consortium (INSIC) roadmap [1]. To achieve these capacities in future tape products, the data track width has to be aggressively reduced through ultra-precise tape head positioning.

Abstract:

Marine waves have the potential of playing a significant role in future energy production. Most converter prototypes utilise a hydrostatic transmission or Power-Take Off (PTO) to convert the mechanical motion of an oscillating body to generate electrical power. A test rig has been installed at the Institute for Fluid Power Drives and Controls (IFAS) together with Aquamarine Power and Bosch Rexroth. Currently a new PTO is tested with this test rig. This new PTO is called WavePOD and is intended to become an industry wide standard by providing flexibility to suit a range of different wave energy converters. Accordingly, it is planned that, different to former PTOs proposed, WavePOD is not designed for only one wave energy converter, but can be used with minor adaptions for various types. Thus, it is aimed to achieve economies of scale, decreasing WavePOD’s costs in comparison to other PTOs. Within this paper important components of the hydraulic transmission such as cylinders, check valves, accumulators and pressure relief valves are investigated in terms of their characteristic behaviour during operation. For the various components the simulation model is presented and validated with test results. Thereby the focus is on dynamic behaviour and power losses. The results will enable to monitor the components behaviour during operation without requiring a surplus of sensor data.

Abstract:

The potential for significant capacity and performance improvements in tape storage systems appears to be substantial [1],[2]. Advances in several areas, however, are necessary to foster increases in linear and track densities and consequently achieve higher cartridge capacities and improved performance [3],[4]. Reliable and precise tape transport and track-following servomechanisms are of fundamental importance to guarantee best read-channel performance on all parallel data channels during tape operation. In particular, tight control of tension and potentially of tape-dimensional stability (TDS) variations will be necessary for moving to thinner tape material, which in turn will enable an increase in volumetric density. Figure 1 shows the block diagram of conventional tape transport and track-following servomechanisms in a tape drive [5]. A digital dual servo channel provides estimates of the tape velocity, tape longitudinal position, and head lateral position, which are derived from signals read from dedicated servo bands [6]. Hall sensors provide tape velocity information from the individual reels, which typically is used in the absence of a valid velocity estimate from the servo channel. One of the main impairments affecting the performance of tape drives is the variation of tape tension [7],[8], which may be induced by, e.g., reel eccentricities.

Abstract:

Abstract Dedicated to the memory of John Furlan. Wear prediction is important in designing reliable machinery for slurry industry. It usually relies on multi-phase computational fluid dynamics, which is accurate but computationally expensive. Each run of the simulations can take hours or days even on a high-performance computing platform. The high computational cost prohibits a large number of simulations in the process of design optimization. In contrast to physics-based simulations, data-driven approaches such as machine learning are capable of providing accurate wear predictions at a small fraction of computational costs, if the models are trained properly. In this paper, a recently developed WearGP framework [1] is extended to predict the global wear quantities of interest by constructing Gaussian process surrogates. The effects of different operating conditions are investigated. The advantages of the WearGP framework are demonstrated by its high accuracy and low computational cost in predicting wear rates.

Abstract:

Some of the important petroleum reservoirs accumulate beneath the seas and oceans. Marine seismic reflection method is the most efficient method and is widely used in the petroleum industry to map and interpret the potential of petroleum reservoirs. Multiple reflections are a particular problem in marine seismic reflection investigation, as they often obscure the target reflectors in seismic profiles. Multiple reflections can be categorized by considering the shallowest interface on which the bounces take place into two types: internal multiples and surface-related multiples. Besides, the multiples can be categorized on the interfaces where the bounces take place, a difference between long-period and short-period multiples can be considered. The long-period surface-related multiples on 2D marine seismic data of the East Coast of the United States-Southern Atlantic Margin were focused on this research. The seismic profile demonstrates the effectiveness of the results from predictive deconvolution and the combination of surface-related multiple eliminations (SRME) and parabolic Radon filtering. First, predictive deconvolution applied on conventional processing is the method of multiple suppression. The other, SRME is a model-based and data-driven surface-related multiple elimination method which does not need any assumptions. And the last, parabolic Radon filtering is a moveout-based method for residual multiple reflections based on velocity discrimination between primary and multiple reflections, thus velocity model and normal-moveout correction are required for this method. The predictive deconvolution is ineffective for long-period surface-related multiple removals. However, the combination of SRME and parabolic Radon filtering can attenuate almost long-period surface-related multiple reflections and provide a high-quality seismic images of marine seismic data.

Abstract:

Liquified natural gas (LNG) as a fuel source for shipping is a ready-made solution for the maritime industry. LNG is a clean fuel that meets the current environmental regulations set by the International Maritime Organization (IMO) to lower the sulfur content of marine fuel from 3.5% to 0.5% by January 2020. LNG is also competitive in terms of price and the increasing availability of fueling terminals. This technological readiness promotes the adoption of LNG powered ships, and the demand for such ships is increasing and is projected to increase in the future. LNG fuelled ships (LFS) comply with the tightened emission regulations, and major industry players have predicted that more than 10% of the world fleet will be using gas as a fuel by 2035. The rapid increase in the design and use of LFS has to be carefully monitored to ensure a successful transition. The design of ship and containment systems for LFS is usually carried out using risk-based design processes. Monitoring and advisory solutions are critical to ensure that changes take place in a safe manner. The experience and lessons learned from designing a suitable database framework and data analytics for traditional ship design are presented, and the knowledge transfer and applications for LFS are discussed. Additional critical parameters that are specific to LFS are discussed, and procedures required to ensure quality data collection to provide necessary solutions for the future fleet are presented. The importance of monitoring quality and quantity of the bunkering process with traditional fuel is outlined along with strategies to adopt and promote infrastructure readiness for the increase in LFS use. Data management and big data analysis for decision making is becoming increasingly apparent in many industries, including the shipping industry. Therefore, the inclusion of the systematic design of data acquisition and analytics systems for newly designed LFS is needed. This will accelerate data-driven knowledge generation and design improvements, promote safe and efficient ship operations, and provide a solid foundation for automation. The synergistic blending of solutions from fuel suppliers, engine makers, containment providers, sensor makers, logistics and government will be needed to ensure the global growth and sustainability of LNG fuelled shipping.

Abstract:

The magnetic data storage industry has followed a similar density (and data rate) improvement curve as the semiconductor technology (Moore’s Law) for the past decade. However, whether the storage densities will continue to increase at this rate and be able to keep up with the improvements in processor technology is under a near term threat resulting from the fundamental physics up on which the hard disk drives are based. It is expected that novel, more unconventional technological solutions become necessary to overcome limitations, however, many of these technologies rely heavily on heating and energy transport at extremely short time and length scales. It is widely believed that further advances in high-technology data storage systems will be difficult, if not impossible, without rigorous treatment of the nano-scale energy transport. The nano-scale heat transfer research effort at Data Storage System Center (DSSC) has been focused on three interwoven areas of thermal design, failure analysis, and metrology of micro/nano-devices and structures relevant to data storage technologies. In this presentation, underlying physics and fundamentals of heat transport at nanoscale will be discussed. In addition, applications of the nanoscale heat transfer to the thermal analyses of the magnetic and phase change optical data storage technologies will be presented.

Abstract:

In the aerospace industry, competition is high and the need to ensure safety and security while managing costs is paramount. Furthermore, stakeholders—who gain the most by working together—do not necessarily trust each other. Now, mix that with changing enterprise technologies, management of historical records, and customized legacy systems. This issue touches all aspects of the aerospace industry, from frequent flyer miles to aircraft maintenance and drives tremendous inefficiency and cost. Technology that augments, rather than replaces, is needed to transform these complex systems into efficient, digital processes. Blockchain technology offers collaborative opportunities for solving some of the data problems that have long challenged the industry. This SAE EDGE™ Research Report by Rhonda D. Walthall examines how blockchain technology could impact the aerospace industry and addresses some of the unsettled concerns surrounding its implementation.
