Operating Model of Knowledge Quantum Engineering for Decision-Making in Conditions of Indeterminacy

The operating model of knowledge quantum engineering for identification and prognostic decision- making in conditions of α-indeterminacy is suggested in the article. The synthesized operating model solves three basic tasks: Аt-task to formalize tk-knowledge; Вt-task to recognize (identify) objects according to observed results; Сt-task to extrapolate (prognosticate) the observed results. Operating derivation of identification and prognostic decisions using authentic different-level algorithmic knowledge quantum (using tRAKZ-method) assumes synthesis of authentic knowledge quantum database (BtkZ) using induction operator as a system of implicative laws, and then using deduction operator according to the observed tk-knowledge and BtkZ a derivation of identification or prognostic decisions in a form of new tk-knowledge.

A simulation analysis of spoke-terminals operating in LTL Hub-and-Spoke freight distribution systems

DUE TO COPYRIGHT RESTRICTIONS ONLY AVAILABLE FOR CONSULTATION AT ASTON UNIVERSITY LIBRARY AND INFORMATION SERVICES WITH PRIOR ARRANGEMENT The research presented in this thesis is concerned with Discrete-Event Simulation (DES) modelling as a method to facilitate logistical policy development within the UK Less-than-Truckload (LTL) freight distribution sector which has been typified by “Pallet Networks” operating on a hub-and-spoke philosophy. Current literature relating to LTL hub-and-spoke and cross-dock freight distribution systems traditionally examines a variety of network and hub design configurations. Each is consistent with classical notions of creating process efficiency, improving productivity, reducing costs and generally creating economies of scale through notions of bulk optimisation. Whilst there is a growing abundance of papers discussing both the network design and hub operational components mentioned above, there is a shortcoming in the overall analysis when it comes to discussing the “spoke-terminal” of hub-and-spoke freight distribution systems and their capabilities for handling the diverse and discrete customer profiles of freight that multi-user LTL hub-and-spoke networks typically handle over the “last-mile” of the delivery, in particular, a mix of retail and non-retail customers. A simulation study is undertaken to investigate the impact on operational performance when the current combined spoke-terminal delivery tours are separated by ‘profile-type’ (i.e. retail or nonretail). The results indicate that a potential improvement in delivery performance can be made by separating retail and non-retail delivery runs at the spoke-terminal and that dedicated retail and non-retail delivery tours could be adopted in order to improve customer delivery requirements and adapt hub-deployed policies. The study also leverages key operator experiences to highlight the main practical implementation challenges when integrating the observed simulation results into the real-world. The study concludes that DES be harnessed as an enabling device to develop a ‘guide policy’. This policy needs to be flexible and should be applied in stages, taking into account the growing retail-exposure.

Investigating the role of capacitive coupling between the operating table and the return electrode of an electrosurgery unit in the modification of the current density distribution within the patients’ body

Background: Electrosurgery units are widely employed in modern surgery. Advances in technology have enhanced the safety of these devices, nevertheless, accidental burns are still regularly reported. This study focuses on possible causes of sacral burns as complication of the use of electrosurgery. Burns are caused by local densifications of the current, but the actual pathway of current within patient's body is unknown. Numerical electromagnetic analysis can help in understanding the issue. Methods: To this aim, an accurate heterogeneous model of human body (including seventy-seven different tissues), electrosurgery electrodes, operating table and mattress was build to resemble a typical surgery condition. The patient lays supine on the mattress with the active electrode placed onto the thorax and the return electrode on his back. Common operating frequencies of electrosurgery units were considered. Finite Difference Time Domain electromagnetic analysis was carried out to compute the spatial distribution of current density within the patient's body. A differential analysis by changing the electrical properties of the operating table from a conductor to an insulator was also performed. Results: Results revealed that distributed capacitive coupling between patient body and the conductive operating table offers an alternative path to the electrosurgery current. The patient's anatomy, the positioning and the different electromagnetic properties of tissues promote a densification of the current at the head and sacral region. In particular, high values of current density were located behind the sacral bone and beneath the skin. This did not occur in the case of non-conductive operating table. Conclusion: Results of the simulation highlight the role played from capacitive couplings between the return electrode and the conductive operating table. The concentration of current density may result in an undesired rise in temperature, originating burns in body region far from the electrodes. This outcome is concordant with the type of surgery-related sacral burns reported in literature. Such burns cannot be immediately detected after surgery, but appear later and can be confused with bedsores. In addition, the dosimetric analysis suggests that reducing the capacity coupling between the return electrode and the operating table can decrease or avoid this problem. © 2013 Bifulco et al.; licensee BioMed Central Ltd.

Random distributed feedback Raman fiber laser operating in a 1.2 μm wavelength range

The random distributed feedback fiber laser operating via the stimulated Raman scattering and random distributed feedback based on the Rayleigh scattering is demonstrated in the 1.2 μm frequency band. The RDFB fiber laser generates at 1174 nm up to 2.4 W of output power with corresponding slope efficiency more than 30%. The output radiation has the spectral shape similar to the conventional Raman fiber lasers and spectral width less than 1.7 nm. © 2011 Pleiades Publishing, Ltd.

Cascaded random distributed feedback Raman fiber laser operating at 1.2 μm

We demonstrate a CW random distributed feedback Raman fiber laser operating in a 1.2 μm spectral band. The laser generates up to 3.8 W of the quasi-CW radiation at 1175 nm with the narrow spectrum of 1 nm. Conversion efficiency reaches 60%. Up to 1 W is generated at the second Stokes wavelength of 1242 nm. It is shown that the generation spectrum of RDFB Raman fiber laser is much narrower than the spectrum in the system without a weak random feedback. © 2011 Optical Society of America.

Let's stick together? Explaining boundaries to territorial policy variation:the case of Germany's prisons legislation

This article offers an initial impact assessment regarding the introduction of new legislative responsibilities at the Land level in a case study of prisons policy (Strafvollzug). Combining an analysis of new legislation produced across the 16 Länder since the responsibility for prisons policy was transferred to the Land level, and insights into the mechanics of policy development obtained through a series of interviews with senior politicians and officials, this article finds that the desire among Länder to legislative independently has varied, with substantial backing for co-ordination in the development of new legislation. This has helped to confound expectations of a ‘competition of harshness’ which many expected to result from decentralisation. However, even before the 2006 reforms, there were substantial variations between the Länder when it came to implementing prisons policy, so consideration of the sub-national level in this area remains essential.

Pyrolysis of Napier grass in a fixed bed reactor:effect of operating conditions on product yields and characteristic

This study presents a report on pyrolysis of Napier grass stem in a fixed bed reactor. The effects of nitrogen flow (20 to 60 mL/min), and reaction temperature (450 to 650 degrees C) were investigated. Increasing the nitrogen flow from 20 to 30 mL/min increased the bio-oil yield and decreased both bio-char and non-condensable gas. 30 mL/min nitrogen flow resulted in optimum bio-oil yield and was used in the subsequent experiments. Reaction temperatures between 450 and 600 degrees C increased the bio-oil yield, with maximum yield of 32.26 wt% at 600 degrees C and a decrease in the corresponding bio-char and non-condensable gas. At 650 degrees C, reductions in the bio-oil and bio-char yields were recorded while the non-condensable gas increased. Water content of the bio-oil decreased with increasing reaction temperature, while density and viscosity increased. The observed pH and higher heating values were between 2.43 to 2.97, and 25.25 to 28.88 MJ/kg, respectively. GC-MS analysis revealed that the oil was made up of highly oxygenated compounds and requires upgrading. The bio-char and non-condensable gas were characterized, and the effect of reaction temperature on the properties was evaluated. Napier grass represents a good source of renewable energy when all pyrolysis products are efficiently utilized.

Pénzgazdálkodási szokások hatása a működőtőkére (The effect of financial management habits on operating capital. The example of the Hungarian Post Office)

A hálózatos iparágakban, ahogy a postai szolgáltatásoknál is, a forgalomban lévő készpénz nagyméretű működőtőkét jelenthet. A Magyar Posta a levél- és csomagkézbesítésen kívül jelentős készpénzforgalmat bonyolít le: nyugdíjakat, segélyeket és készpénz-átutalási megbízásokat továbbít. A forgalom napi ingadozása a vállalat likvideszköz-igényét jelentősen meghatározza. A posta esetében a postahivatalok készpénzgazdálkodása jól működő hüvelykujjszabályokon keresztül történik, ezek a szabályok döntési teret hagynak a hálózat heterogén egyedi szereplőinek. Az egyedi készletezési viselkedést a vállalati működőtőke meghatározásakor figyelembe kell venni. A tanulmány az egyedi készletezési szokások modellezésére új módszertant ajánl, majd a viselkedésmintákat csoportosítva a pénzkészletezésnek, a vállalati működőtőke szintjének és a vállalati likviditási pozíciónak a kapcsolatát elemzi. / === / The cash in circulation within network industries such as post-office services can repre-sent a sizeable quantity of operating capital. The Hungarian Post Office, besides han-dling mail, handles a significant amount of cash turnover, forwarding pensions, welfare benefits, and cash orders. Fluctuation in the daily volume of these is a strong factor in determining the company's liquidity requirements. The management of cash in post of-fices is governed by rules of thumb that operate well; the regulations leave decision-making scope for the diverse individual actors in the network. Attention has to be paid to individual cash holding when determining the corporate operating capital. The study suggests a new methodology for modelling the individual cash-holding habits, and goes on to group the behaviour patterns by analysing the connection between cash holding, level of corporate operating capital, and corporate liquidity position.

Üzleti teljesítménymérés a sportban, - avagy miként segítheti a sportszervezetek vezetőit a Balanced Scorecard koncepció a stratégia szerinti működésben = Measuring Business Performance in Sports - How the Balanced Scorecard approach can help sports organisations in operating along strategic objectives

Napjainkban egyre nagyobb figyelem fordul a sporttevékenység társadalmi hasznosságára, ugyanakkor számos sportszervezet a túléléséért küzd. A legtöbb sportszervezetnél a sportteljesítmény mérése dominál, s viszonylag kevés figyelmet fordítanak az üzleti teljesítmény és az ezt befolyásoló tényezők mérésére, annak ellenére, hogy a vezetők tudatában vannak a sportteljesítmény és az üzleti teljesítmény kölcsönös összefüggésével. A sportteljesítményt a fogyasztói elégedettségen keresztül bevételre kell váltani, illetve biztosítani kell a finanszírozási forrásokat (gondolhatunk akár a játékosok fizetésére) a megfelelő sportteljesítmény eléréséhez. A sportszervezetek vezetőinek át kell látniuk a sportteljesítmény és az üzleti teljesítmény összefüggéseit, és azonosítaniuk kell a kritikus értékteremtő tényezőket. Ehhez adhat egy megfelelő gondolkodási keretet a Balanced Scorecard alkalmazása. Tanulmányunkban egy rövid áttekintést adunk a Balanced Scorecard alkalmazásának előnyeiről és kihívásairól a non-profit szervezetek esetében, majd egy magyarországi kézilabda klubnál készített esettanulmány segítségével megvizsgáljuk a BSC alkalmazási lehetőségét a sportkluboknál. _____ While performance measurement in the sport industry has a traditionally strong focus on sports results, commercial success of sports clubs needs to gain more ground. Sports results should generate market revenues, by satisfying customer needs, and allow continued investment in the further improvement of sports success (i.e. more funds for player transfers and wages). Club managers need to understand the complex relationship between on-field and off-the-field success, and identify critical success factors for achieving strategic objectives. The Balanced Scorecard approach provides a plausible framework for such analysis. Our paper explains the challenges of and opportunities for implementing a Balanced Scorecard system in non-profit organisations, and provides insights into its application in professional sport through an in-depth case study of a handball club in Hungary. We conclude by providing a model for managing sports organisations in line with strategic objectives, balancing out stakeholder expectations for both sports results and commercial success.

Az egyéni teljesítményértékelési rendszer működésének tapasztalatai a magyar közigazgatásban (Operating experiences of the individual performance appraisal system in the Hungarian public sector)

A tanulmány – egy 2005 végén lefolytatott, országosan reprezentatív kérdőíves felmérés empirikus bázisán – a magyar közigazgatási dolgozók körében 2002-től bevezetett egyéni teljesítményértékelési rendszert vizsgálja. A rendszer egészét tekintve a vizsgálat végkövetkeztetései nem túl rózsásak: az eredmények arra utalnak, hogy a rendszer mint egész nem képes kitűzött fő célját, a munkateljesítmények javítását elérni. Az egyes részrendszerek, szervezettípusok szintjén differenciáltabb eredményeket kapunk, míg a minisztériumokban a rendszer egésze a szándékolttól alapvetően különböző célokat látszik szolgálni, addig a többi szervezettípusnál inkább „csak” a rendszer tökéletlen működéséről beszélhetünk. ____ On the basis of a questionnaire survey of a nationally representative sample of Hungarian civil servants, the study attempts to give a preliminary evaluation of the individual performance assessment system introduced in 2002 throughout the Hungarian civil service. The general conclusion of the analysis is that the performance assessment system is unlikely to reach its goals: its central element, the performance related pay incentives are overly dispersed and, on the average, insignificant in size, meanwhile the objectivity of performance assessments is also questionable. Moreover, comparative analysis of responses from different administrative branches reveals an interesting idiosyncrasy characteristic for central government ministries. Here, the main function of the incentive system seems to be ensuring the labor market competitiveness of the ministries as employers by enabling them to pay higher-than-usual salaries for employees having certain types of expertise.

A biológiai sokféleség megőrzése. Az élet sokszínűsége

A Magyar Természetvédők Szövetsége a svájci Pro Natura Természetvédelmi Szervezettel közösen 15 hónapos programot dolgozott ki a biológiai sokféleség magyarországi megőrzését elősegítendően, amelyre a svájci kormánytól kaptunk támogatást. A programon belül képzéseket, konferenciát, svájci tanulmányutat szerveztünk, majd a befejező szakaszban helyi társadalmi kampányokkal igyekszünk a lakosság figyelmét felhívni a probléma súlyosságára, és e program keretében határoztuk el e kiadvány megjelentetését is. A kiadvány célja, hogy felhívja a figyelmet a biológiai sokféleség hanyatlására, annak létünket veszélyeztető következményeire. Tudatosítani szeretnénk a biológiai sokféleség megőrzésének fontosságát és azt, hogy minden egyes ember tehet ezért. Röviden bemutatjuk a hanyatlás megállításával összefüggő nemzetközi és hazai erőfeszítéseket, de a kudarcokat is. Megfogalmazzuk legfontosabb üzeneteinket a követendő irányra vonatkozóan. A hazai és svájci példákon, jó gyakorlatokon keresztül azt is bemutatjuk, hogy a civil szervezetek munkájuk során mit tesznek a természeti értékek megóvásáért, bízva abban, hogy példájuk követésre talál.

Van-e élet az EU-n túl? (Az Egyesült Királyság EU-tagságának alternatívái)

A tanulmány azt vizsgálja, hogy az Egyesült Királyság milyen lehetőségek közül választhat, ha kilépne az Európai Unióból. David Cameron 2013. elején kilátásba helyezte, hogy újraválasztása esetén 2017-ben népszavazást ír ki országa EU-tagságáról. A téma igen aktuális, mégis az tapasztalható, hogy legtöbbször csak az EU-tagság hátrányáról esik szó, nem pedig a kilépés utáni konkrét következményekről. Az EU-tagság alternatíváinak elemzése ezt a hiányosságot próbálja meg pótolni. Két nagy csoportra lehet bontani ezeket:egyrészt a létező (norvég, svájci, török modell), másrészt a nem létező, csak elképzelt alternatívákra (AEA, NAFTA, EU+1, Commonwealth, WTO). A tanulmány végére kiderül, hogy a lehetőségek számos olyan problémával rendelkeznek, amelyeket EU-tagként nem lehet érzékelni. Így az is előfordulhat, hogy a kevésbé népszerű EU-tagság is előnyösebb lehet, mint a kilépés utáni alternatívák. Az elemzés mindenki számára hasznos lehet, akik az EU-n kívüli élet dilemmáit szeretnék jobban megérteni.

What makes online grocers work? A case study analysis of factors contributing to online grocery store profitability

This research examined the factors contributing to the performance of online grocers prior to, and following, the 2000 dot.com collapse. The primary goals were to assess the relationship between a company’s business model(s) and its performance in the online grocery channel and to determine if there were other company and/or market related factors that could account for company performance. ^ To assess the primary goals, a case based theory building process was utilized. A three-way cross-case analysis comprising Peapod, GroceryWorks, and Tesco examined the common profit components, the structural category (e.g., pure-play, partnership, and hybrid) profit components, and the idiosyncratic profit components related to each specific company. ^ Based on the analysis, it was determined that online grocery store business models could be represented at three distinct, but hierarchically, related levels. The first level was termed the core model and represented the basic profit structure that all online grocers needed in order to conduct operations. The next model level was termed the structural model and represented the profit structure associated with the specific business model configuration (i.e., pure-play, partnership, hybrid). The last model level was termed the augmented model and represented the company’s business model when idiosyncratic profit components were included. In relation to the five company related factors, scalability, rate of expansion, and the automation level were potential candidates for helping to explain online grocer performance. In addition, all the market structure related factors were deemed possible candidates for helping to explain online grocer performance. ^ The study concluded by positing an alternative hypothesis concerning the performance of online grocers. Prior to this study, the prevailing wisdom was that the business models were the primary cause of online grocer performance. However, based on the core model analysis, it was hypothesized that the customer relationship activities (i.e., advertising, promotions, and loyalty program tie-ins) were the real drivers of online grocer performance. ^
