Påverkad strukturerad produktion produktiviteten? : Analys av mätningar från byggbranschen

The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.

Interaktiva applikationers potential på internet - en kvalitativ studie av Saab Automobile AB

Saabs vision med de interaktiva applikationerna är att de ska tilltala både den nya besökaren och den lojale Saabkunden. Vi observerade tydliga attitydförändringar när applikationerna inte fungerade. Få kunde tänka sig att köpa en bil efter att enbart ha besökt Saabs hemsida då applikationerna i dagsläget inte kan ersätta känslan av att manövrera bilen själv. För att öka graden av ?stickiness? och ?flow? kan Saab integrera applikationerna i en värdekedja.

MEASUREMENT OF C-REACTIVE PROTEIN IN CANINE SERUM ON KONELABAUTOANALYZER 20

An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.

Feromoninnehållande substansers inverkan på hjärtfrekvensen hos tjur :

During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

Att genomföra projekt - Två teoretiska perspektiv på ett problemfyllt projekt i ett kunskapsföretag

This thesis examines a project that has been conducted at a software development company. The aim is to investigate which problems firms of this kind faces performing projects. We choose a theoretical frame consisting of a modern view on how to manage projects. The view argues that the management of each project has to be adapted to the situation at hand. This theory is divided into two separate streams of reasoning; one emphasize learning, delegation of responsibility and flexibility, while the other argues for control, time planning and the importance of keeping to the plans.When we compare the theories to the case we draw three main conclusions: A thorough phase of investigation is required to produce the necessary planning documents.

"Det är svårt att få dem att stanna längre än tre år" : måste rekryteringsprocessen förändras för att tillfredsställa unga medarbetares krav?

How does a corporation work during the recruitment phase to entice and motivate younger members to work for their organization?The aim is to examine in which grade corporations and organizations? recruitment needs to adapt to encounter Generation Y on the labour market.The base in our method is abduction and our research is based on a qualitative method. We have fulfilled interviews with corporations such as Scania, Skatteverket, Swedbank and Appelqvist & Ottoson HR AB.Corporations need in a sense change their recruitment and emphasis their resources to sell the whole corporation and its image to the young job applicant. The younger members demand a total impression of the corporation to implement an interest and to get motivated to work there. Together with our respondents we have realized that Generation Y has higher demands on their workplace than earlier generations..

Klinisk termografi som diagnostiskt hjälpmedel vid rörelsestörning hos häst :

Thermography is the assesment of the surface temperature of the horses body and it falls into the categori of physiological imaging. Thermography allows us to portray inflammation and changes in sympathetic tone in a graphical manner. The purpose of this study was to review thermography in equine medicine and to evaluate thermography as an aid in the diagnosis of lamness in horses. Thermography has been helpful to identyfy sprains, stress fractures, shin splints and soft tissue, tendon, ligamentous and nerv injuries and to monitor healing processes during rehabilitation. Routine thermography may reveal inflammatory responses prior to clinical signs. In present study thermograpy gave especially valuabel information in two cases. In one horse reduced blood flow in a. saphena due to a thrombosis were visualised and in the other horse bilateral thoracolumbal radiculopati was diagnosed.

Identifiering av parametrar för tillståndsbedömning av en vattenkraftstation

The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..

Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Den interna informationshanteringen inom äldre- och handikappomsorgen i kommundelen Viskafors

The purpose of this thesis is to explore how the internal information processing and management is carried out within a unit of Viskafors municipality. Furthermore, to explore and make recommendations of how the organisation can improve its internal information management. To get a full picture I have interviewed people at different levels of the organisation. The main findings showed that there was a dysfunction in the internal information processing and management. For example the study showed that the internal information did not reach out to the different parts of the organisation due to insufficient information processing.

Omloppstid för returenheter

Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.

Modellbygge och regulatordesign av tröghetsmomentsimulator tillreferenssystem för stridsvagn 122

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.
