Analysing the Current State of a Warehouse -A Framework Based on VSM, Activity Profiling and Benchmarking

The 21st century has brought significant changes to the market. The ability to deliver the right product at the right time with the right price is no longer just crucial for a company’s competitive success, in the long-term perspective it will decide if the company will survive on the market at all. A warehouse has a major impact on a firm’s service levels, response times and overall cost. To meet customer requirements and to keep up with the ever-changing market there is a need of improving warehouse operations. For this study, a framework with Value Stream Mapping (VSM) in combination with Activity Profiling and Benchmarking is developed. VSM visualises the flow of material and information in a process and it is a concept commonly used for industrial improvements. The use of VSM in warehouses is however lagging behind. Activity Profiling is used to understand the activities and operations connected to a warehouse and Benchmarking is the process of gathering and sharing assessments of performance. It is believed that the combination will give a more comprehensive result compared to applying only one of the concepts. To meet the purpose of the thesis a case company is used, Alfa Laval in Lund. Alfa Laval has two warehouses at the site that will be used to examine and evaluate the framework. The purpose of the study is to investigate how the framework is applicable to present a current situation analysis of a warehouse. The aim of combining the three different concepts is to create a framework that takes several aspects into account in order to establish a fair picture of the warehouse state. For this study “the research process onion” serves as an outline for the methodology. Data collection is in the centre of the model and the core of this method. Interviews, observation and secondary data have been used for the data collection to receive a fair picture of the current state in the two warehouses at Alfa Laval. With the framework data are analysed and improvement areas are identified. A proposal is given of where Alfa Laval could build a new warehouse at the site. It is then analysed how the three concepts contributed to given recommendations and identified improvements. The three concepts complement each other in many ways and it is recommended to use them together when evaluating the current warehouse state and to find areas of improvement.
Discovering Clusters of Plagiarism in Students’ Source Codes

Plagiarism in students’ source codes constitutes an important drawback for the educational process. In addition, plagiarism detection in source codes is time consuming and tiresome task. Therefore, many approaches for plagiarism detection have been proposed. Most of the aforementioned approaches receive as input a set of source files and calculate a similarity between each pair of the input set. However, the tutor often needs to detect the clusters of plagiarism, i.e. clusters of students’ assignments such as all assignments in a cluster derive from a common original. In this paper, we propose a novel plagiarism detection algorithm that receives as input a set of source codes and calculates the clusters of plagiarism. Experimental results show the efficiency of our approach and encourage us to further research.

Platelet parameters as an inflammatory marker in children

Introduction: Platelets which are known to play a role in inflammation change their number and shape when they are activated and this change is reflected in values of platelet indices . Testing for platelet parameters by reliable automated blood cell counters is inexpensive, easily accessible and routinely performed that had been recognized as a hallmark in the diagnosis of platelet activation during infection and inflammatory disorders. The aim of this study was to investigate the relationship between white blood cell count(WBC), which is known inflammatory marker and platelet count (PLT) and its parameters including mean platelet volume(MPV), platelet distribution width(PDW), plateletcrit (PCT) and platelet- large cell ratio (P-LCR) in all clinical setting of leukocytosis in children. Methods: White blood cell counts and all platelet parameters were evaluated in 156 children with elevated white blood cell counts (group 1) and 191children with normal white blood count (group 2) and the results of two groups were compared and statistically analysed. Results: There is a association between WBC and platelet count but there is very low correlation exist and correlation is significant. There was a significant difference between the two groups in WBC counts, PLT counts, PCT and PDW values ( p <0.01), being higher in Group 1. However, there was no statistically significant difference between two groups in MPV and P-LCR values ( p >0.05). Conclusion: Platelet count and PDW values are significant in infectious conditions. And no significant role of PCT, MPV and P-LCR values found in such conditions.
Evolution of spin direction of accreting magnetic protostars and spin-orbit misalignment in exoplanetary systems

Abstract Recent observations have shown that in many exoplanetary systems the spin axis of the parent star is misaligned with the planet's orbital axis. These have been used to argue against the scenario that short-period planets migrated to their present-day locations due to tidal interactions with their natal discs. However, this interpretation is based on the assumption that the spins of young stars are parallel to the rotation axes of protostellar discs around them. We show that the interaction between a magnetic star and its circumstellar disc can (although not always) have the effect of pushing the stellar spin axis away from the disc angular momentum axis toward the perpendicular state and even the retrograde state. Planets formed in the disc may therefore have their orbital axes misaligned with the stellar spin axis, even before any additional planet-planet scatterings or Kozai interactions take place. In general, magnetosphere–disc interactions lead to a broad distribution of the spin–orbit angles, with some systems aligned and other systems misaligned.
Anthropogenic food patches and association patterns of Tursiops truncatus at Lampedusa island, Italy

Anthropogenic food patches in the marine environment, such as aquaculture farms and active trawlers, may impact on the behavior of marine mammals through modification of habitats, changes in predation pressure, or alterations in food distribution, availability, and predictability, affecting related social interactions and population demographics. This study examined patterns of association of a population of common bottlenose dolphins (Tursiops truncatus) around Lampedusa Island (Italy) during 1996–2006 and tested the hypothesis that the trawl fishery and the presence of an aquaculture farm could affect such patterns. Here, we used measures of association between pairs of individuals to assess this impact on social unit composition/cohesion and some analytical techniques to describe the structure of dolphin social networks and temporal stability of associations. Association information for 71 regularly sighted individuals was obtained from photo-identification surveys within groups observed or not at "feeding stations. " We found association patterns between dolphins were nonrandom. The Lampedusa population seems to be arranged into 6 clusters and organized in communities composed of animals that were either never seen in association with feeding stations (N individuals) or those that are (Y individuals), although mixed assemblages were also recorded. Both communities showed long-term preferred companions, with different degrees of social cohesion—as resulted by network measures and temporal analysis. Delineating community structure at Lampedusa Island has offered basic information for further investigations in the area, also providing novel evidences on how disparities in association patterns between bottlenose dolphin individuals may have resulted from a combination of ecological and anthropogenic factors.
The chemical gradient of oxygen in the Galaxy from planetary nebulae

The chemical gradient of oxygen in the Galaxy from planetary nebulae (PNe) has been closely investigated using a recent extensive fully homogenous set of chemical determinations (up to end of 2001) and various distant scales. The found gradient is quite flatter than believed so far, amounting to about −0.016 ± 0.008 log(O/H) kpc−1 insensitive to the distance scales, when all PNe of types I, II, III of Peimbert are used. The value is −0.02 ± 0.01 if only type II PNe are considered, thus reducing the ambiguity introduced by the mixing up of progenitors coming from a large spread in mass. A second control set made by the chemical oxygen abundances determined by all studies between 2002 and 2005, with a data base of some 200 objects, provides a similar result. Since previous determinations do have a spread in the slope of the galactocentric oxygen gradient from PNe between −0.07 and −0.01, further work is required to assess the matter. If our low value will be confirmed, the suggestion arises that type II PNe, due to mixing processes, might have lost their ability to be good tracers of oxygen abundance in the interstellar medium at the time of formation of the progenitors.
An Internet-Wide View of Self-Revealing Honeypots

Open-source honeypots are a vital component in the protection of networks and the observation of trends in the threat landscape. Their open nature also enables adversaries to identify the characteristics of these honeypots in order to detect and avoid them. In this study, we investigate the prevalence of 14 open-source honeypots running more or less default conﬁgurations, making them easily detectable by attackers. We deploy 20 simple signatures and test them for false positives against servers for domains in the Alexa top 10,000, ofﬁcial FTP mirrors, mail servers in real operation, and real IoT devices running telnet. We ﬁnd no matches, suggesting good accuracy. We then measure the Internet-wide prevalence of default open-source honeypots by matching the signatures with Censys scan data and our own scans. We discovered 19,208 honeypots across 637 Autonomous Systems that are trivially easy to identify. Concentrations are found in research networks, but also in enterprise, cloud and hosting networks. While some of these honeypots probably have no operational relevance, e.g., they are student projects, this explanation does not ﬁt the wider population. One cluster of honeypots was conﬁrmed to belong to a well-known security center and was in use for ongoing attack monitoring. Concentrations in an another cluster appear to be the result of government incentives. We contacted 11 honeypot operators and received response from 4 operators, suggesting the problem of lack of network hygiene. Finally, we ﬁnd that some honeypots are actively abused by attackers for hosting malicious binaries. We noti-ﬁed the owners of the detected honeypots via their network operators and provided recommendations for customization to avoid simple signature-based detection. We also
Reproductive maturity and cone abundance vary with tree size and stand basal area for two widely distributed conifers

Understanding potential limitations to tree regeneration is essential as rates of tree mortality increase in response to direct (extreme drought) and indirect (bark beetle outbreaks, wild ﬁ re) effects of a warming climate. Seed availability is increasingly recognized as an important limitation for tree regeneration. High variability in seed cone production is a trait common among many northern temperate conifers, but few studies examine the determinants of individual tree cone production and how they vary with stand structure. In subalpine forests in the southern Rocky Mountains, USA, we monitored >1600 Picea engelmannii (Engelmann spruce) and Abies lasiocarpa (subalpine ﬁ r) trees for cone presence (an indicator of reproductive maturity) and a subset of those trees for cone abundance (an indicator of seed production) from 2016 to 2018. We constructed mixed models to test how individual tree cone presence and cone abundance were affected by tree size and age as well as forest attributes at the neighborhood- and stand-scales. The probability of cone presence and cone abundance increased with tree size and age for A. lasiocarpa and P. engelmannii . The youngest ages of trees with cones present were more than 100 yr later for individuals in high basal area (BA) stands (>65 m 2 /ha) relative to low BA stands (<25 m 2 /ha). P. engelmannii produced many more cones than A. lasiocarpa at similar sizes, especially in young, low BA stands. Our ﬁ ndings reveal how differences in tree sizes and stand structures typically associated with time since last disturbance can affect seed production patterns for decades to well over a century. The consistent regional pattern of earlier and more abundant post ﬁ re establishment of P. engelmannnii vs. the delayed post ﬁ re establishment by A. lasiocarpa may be partially explained by species ’ differences in cone abundance by stand structure. The increasing loss of large, dominant cone-producing trees will signi ﬁ cantly reduce seed production to support future tree regeneration and maintain forest cover. However, seed availability and resilience following disturbances may be less limiting than expected for species like P. engelmannii that have the capacity to produce more cones in open-canopy forests, such as recently disturbed areas.
Title Differential maturation and subcellular localization of severe acute respiratory syndrome coronavirus surface proteins

Received 7 October 2004 Accepted 10 January 2005 Post-translational modifications and correct subcellular localization of viral structural proteins are prerequisites for assembly and budding of enveloped viruses. Coronaviruses, like the severe acute respiratory syndrome-associated virus (SARS-CoV), bud from the endoplasmic reticulum-Golgi intermediate compartment. In this study, the subcellular distribution and maturation of SARS-CoV surface proteins S, M and E were analysed by using C-terminally tagged proteins. As early as 30 min post-entry into the endoplasmic reticulum, high-mannosylated S assembles into trimers prior to acquisition of complex N-glycans in the Golgi. Like S, M acquires high-mannose N-glycans that are subsequently modified into complex N-glycans in the Golgi. The N-glycosylation profile and the absence of O-glycosylation on M protein relate SARS-CoV to the previously described group 1 and 3 coronaviruses. Immunofluorescence analysis shows that S is detected in several compartments along the secretory pathway from the endoplasmic reticulum to the plasma membrane while M predominantly localizes in the Golgi, where it accumulates, and in trafficking vesicles. The E protein is not glycosylated. Pulse-chase labelling and confocal microscopy in the presence of protein translation inhibitor cycloheximide revealed that the E protein has a short half-life of 30 min. E protein is found in bright perinuclear patches colocalizing with endoplasmic reticulum markers. In conclusion, SARS-CoV surface proteins S, M and E show differential subcellular localizations when expressed alone suggesting that additional cellular or viral factors might be required for coordinated trafficking to the virus assembly site in the endoplasmic reticulum-Golgi intermediate compartment.
NATURAL INTEREST RATE

We document a rise and fall of the natural interest rate (r∗) for several advanced economies, which starts increasing in the 1960’s and peaks around the end of the 1980’s. We reach this conclusion after showing that the Laubach and Williams (2003) model cannot estimate r∗ accurately when either the IS curve or the Phillips curve is flat. In those empirically relevant situations, a local level specification for the observed interest rate can precisely estimate r∗. An estimated Panel ECM suggests that the temporary demographic effect of the young baby-boomers mostly accounts for the rise and fall. JEL Codes: E43, E52, C32
Achieving involvement : process outcomes from a cluster randomized trial of shared decision making skill development and use of risk communication aids in general practice

Elwyn G, Edwards A, Hood K, Robling M, Atwell C, Russell I, Wensing M, Grol R and the Study Steering Group. Achieving involvement: process outcomes from a cluster randomized trial of shared decision making skill development and use of risk communication aids in general practice. Family Practice 2004; 21: 337–346. Background. A consulting method known as ‘shared decision making’ (SDM) has been described and operationalized in terms of several ‘competences’. One of these competences concerns the discussion of the risks and benefits of treatment or care options—’risk communication’. Few data exist on clinicians’ ability to acquire skills and implement the competences of SDM or risk communication in consultations with patients. Objective. The aims of this study were to evaluate the effects of skill development workshops for SDM and the use of risk communication aids on the process of consultations. Methods. A cluster randomized trial with crossover was carried out with the participation of 20 recently qualified GPs in urban and rural general practices in Gwent, South Wales. A total of 747 patients with known atrial fibrillation, prostatism, menorrhagia or menopausal symptoms were invited to a consultation to review their condition or treatments. Half the consultations were randomly selected for audio-taping, of which 352 patients attended and were audio-taped successfully. After baseline, participating doctors were randomized to receive training in (i) SDM skills or (ii) the use of simple risk communication aids, using simulated patients. The alternative training was then provided for the final study phase. Patients were allocated randomly to a consultation during baseline or intervention 1 (SDM or risk communication aids) or intervention 2 phases. A randomly selected half of the consultations were audio-taped from each phase. Raters (independent, trained and blinded to study phase) assessed the audio-tapes using a validated scale to assess levels of patient involvement (OPTION: observing patient involvement), and to analyse the nature of risk information discussed. Clinicians completed questionnaires after each consultation, assessing perceived clinician–patient agreement and level of patient involvement in decisions. Multilevel modelling was carried out with the OPTION score as the dependent variable, and rater, consultation and clinician levels of data, standardized by rater within clinician. Results. Following each of the interventions, the clinicians significantly increased their involvement of patients in decision making (OPTION score increased by 10.6 following risk communication training [95% confidence interval (CI) 7.9 –13.3; P 0.001] and by 12.9 after SDM skill development (95% CI 10 –15.8, P 0.001), a moderate effect size. The level of involvement achieved by the risk communication aids was significantly increased by the
Unsteady Stokes Flow through a Porous Pipe with Periodic Suction and Injection with Slip Conditions

The problem of unsteady Stokes flow of certain Newtonian fluids in a circular pipe of uniform cross section is discussed. The pipe is uniformly porous. The unsteady Navier-Stokes equations for the system in cylindrical polar coordinates have been solved analytically to obtain a complete description of the flow. The solution of the flow equations subject to the slip boundary conditions leads to the detailed expressions for axial and radial components of velocity and the pressure distribution depending on position coordinates and time. As a special case we have presented the situation when no-slip boundary conditions are implemented. The velocity profile is analyzed for different values of the flow parameters like Womersley number, slip length and time.
Is Mononykus a bird

The avian status of Mononykus is refuted in this paper through a detailed analysis of its supposed avian characters. An extensive comparison between it and fossorial mammals (especially moles), as well as various bipedal archosaurs, indicates that some of its resemblances to extant birds are digging adaptations. Most of the others can be explained either by its digging adaptation or by its obligatory bipedalism, in addition, many of its features, as compared with birds (including Archaeopteryx), seem to be too primitive for avian night, and there is no evidence indicating that the absence of night in Mononykus was secondarily lost.

A credit mechanism in coordinating quality level, pricing and replenishment decisions with deteriorating items

In this paper, we present a two-level supply chain (SC) consisting of a single manufacturer that suppling one type of deteriorating product to a single retailer that the market demand rate for the product is time-varying and depends on two endogenous variables that include the retail price and product quality. The objective of this paper is to determine simultaneously pricing policy and ordering for the retailer, as well as product quality optimizing strategy for the manufacturer. Firstly, the problem is formulated under a decentralized structure with a manufacturer-Stackelberg game where each member optimizes his/her decisions regardless of the others’ profitability. Next, a centralized structure was presented and optimized based upon the whole SC profitability. Although the centralized model improves the quality level of the product and profitability of the entire SC, it may reduce the profitability of each SC members. Then, this paper is developed with an incentive scheme based on credit policy to coordinate this system. Moreover, Numerical examples and sensitivity analysis are presented to indicate the effectiveness of the contract. The results show that the credit contract can lead to perfect coordination, while the coordinated system is more robust than the centralized system. This paper extends the understanding of supply chain coordination in the context of deteriorating items that indisputably have a reciprocal relationship with market time-varying demand in many real-life cases.
