RFID-teknik i cross-dockinglager - En studie av Speed Logistics lagerverksamhet

Logistik är mer än transporter mellan olika platser. Stor del av ett företag och dess logistik kretsar kring de interna logistikfunktioner och hur de som företag ständigt jobbar för att förebygga flaskhalsar. En lagervariant som används för att skapa ett högre värde i en kedja är ett så kallat cross-dockinglager. I ett sådant förs ständigt ett arbete med att effektivisera processer med hjälp av olika tekniker och strategier. En teknik för att öka omsättningshastigheten i ett lager genom snabbare identifiering och spårning av gods som hanteras är Radio Frequency Identification (RFID).Syftet med studien är att belysa de ständigt återkommande problemområden som uppstår i ett cross-dockinglager samt hur en RFID-lösning skulle kunna stödja dess verksamhet.

Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable Speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variableSpeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Ridhästens samling : en jämförelse av subjektiva bedömningar och objektiv kinematisk analys

The modern veterinarian in horse practice is often consulted by horse owners concerning riding problems. These problems are more complex and show other characteristics than traditional lameness. For the diagnostic process and to give adequate advice the veterinarians need an understanding of riding terminology and problems related to riding. It is also of high importance that riders, trainers and veterinarians increase the knowledge of equine biomechanics and how these are influenced by the rider. Collection is an important concept in the riding terminology.

Matarverk för Camcoil

By our employer Camatec Industriteknik AB have we been given the assignment to continue with the previous work ?Design of strip feeder?. Our goal with this work is to come up with a design basis for a strip feeder.Functionally a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ? 600 mm in strip width and 0,1-1 mm in strip thickness.? Minimum 30m/min in production Speed.? A maximum strip force on 30-40 kN.? The cost of the strip feeder?s components is to be considered of economy and quality.The need of a strip feeder occurs when the coil doesn?t manage to feed or pull the strip before or after a working process. The strip can otherwise be exposed by a permanent yield deformation or a change in the strip material if it?s pulled trough the working process only by the on ? and of-coils.

Utökning av mätområdet för turbinverkningsgraden på avgasturbo

The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.

Ombyggnad av flerbostadshus : Hur påverkas hyresgästerna av  en ombyggnad

During the years 1950-75 was the construction of building apartments in high Speed. A rapidly growing reconstruction requirement is the consequence of the rapid construction Speed in these years. The technical lifetime of the different parts of the buildings is about to end and the needs for reconstruction is huge. One of Sweden's national environmental objectives is to reduce the urge of energy in buildings. This calls for radical measures to implement energy efficiency of existing assistance particularly in the assistance that is now facing reconstruction.

Ökad kapacitet i Stockholms kollektivtrafik - Kan T-Centralen med enkla finansiella medel öka sin kapacitet

By conducting interviews, studies as well as scanning the current scientific landscape, this paper examines the opportunities of increasing current capacity within the public transportation system in Stockholm with simple financial means for the benefit of the travelers. The paper focuses on the central station of the subway system and how adjustments of processes carried out in relation to the turnstiles could increase performance within areas of interest, given the preferences of the travelers. The theoretical framework of the paper includes models from the field of capacity management as well as theories related to the pedestrian behavior. Applying these theories and models to the collected data, the paper derives some main conclusions. First of, people using the public transportations system, and especially the subway, consider Speed and dependability as the most important performance objectives for the caretakers of the public transportation system, SL and MTR to master.

Läsförmågans faktorer och deras bidrag till läsning : En jämförelse mellan barn med olika nivå av läsförmåga, utifrån The Simple View of Reading

The simple view of reading is a theory in which reading is divided into decoding and linguistic comprehension. The theory has been used to explain and to subgroup reading disabilities. Research has also investigated if additional factors are of relevance to reading. In the present study, decoding was divided into the factors orthographic decoding and phonological decoding, while comprehension was divided into word comprehension and grammatical comprehension. The purpose was to analyze these factors and their contribution to reading ability in children in fourth grade: one group with reading difficulties (n=36) and one group with typical reading ability (n=36).

Fröplacering vid hög såhastighet - Väderstad Rapid jämfört med Amazone Cirrus

In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work Speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different Speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different Speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.

Utvärdering av Capcals förmåga att beräkna framkomlighet

Performance of an intersection affects the total travel time in a traffic network. An intersection with good performance can easily be described by its contribution to lower travel time than in a comparable intersection. The travel time is of importance in the cost calculations when a specific intersection is to be chosen and designed. It is important to be able to make correct and precise performance calculations so that the cost calculations will not be incorrect. For that purpose the software Capcal, which is a traffic model for intersection analysis on performance, is used in Sweden.

Korrelationen mellan fotgängares skador i verkliga olyckor och Euro NCAPs testresultat för fotgängarskydd

The aim of the present study was to estimate the correlation between Euro NCAP pedestrian rating scores and injury outcome in real-life car to pedestrian crashes, with special focus on long-term disability. The study also surveyed most frequently injured body regions and risk differences for specific elements of pedestrians hit by cars. Another aim was to determine whether Brake Assist systems affect the injury outcome in real-life car to pedestrian crashes and to estimate the effect in injury reduction of a high Euro NCAP ranking score combined with Brake Assist.In the current study, the Euro NCAP pedestrian scoring was compared with the real-life outcome in pedestrian crashes that occurred in Sweden 2003-2010. The real-life crash data was obtained from the data acquisition system STRADA, which combines police records and hospital admission data. The medical data consisted of International Statistical Classification of Diseases and Related Health Problems (ICD) diagnoses and Abbreviated Injury Scale (AIS) scoring.

Jaktprov hos brittiska stående fågelhundar

In 1996 a hunting test for British gun dogs was started in Sweden, based on a similar one al-ready in place in Norway. The aim of the new test was to describe the hunting ability of the dog and to use the results as a basis for selection. However, up to now, no genetic study of these data has been done. Therefore the aim of this study was to estimate genetic parameters for the traits measured in the hunting test and to investigate whether the traits can summarized into fewer overall measures. Data from trails of British gundogs between 1996 and 2005 in Sweden were used to estimate genetic parameters and environmental effects in hunting performance. British gundogs consist of five different breeds: Pointer, English setter (ES), Gordon setter (GS), Irish red setter (Irl S) and Irish red and white setter.
